One of the common sense of locks

Lock, although a humble hardware commodity, has a very close relationship with people and society, which is related to the safety of every family, unit and public place. Lock is a special commodity, which has a very important relationship with safety. Therefore, whether at home or abroad, the lock industry has a set of extremely strict quality standards and safety requirements. At present, the market inspection situation of the technical supervision department has reflected that the quality of locks in the market is uneven, with both advantages and disadvantages. It can be seen that in order to covet market profits, some enterprises ignore the product quality with a very irresponsible attitude and push the products that do not meet the quality standards to the market, which has brought trouble and trouble to consumers and directly damaged the interests of consumers.

Unqualified products are mainly manifested in poor confidentiality, high mutual opening rate and low durability, which are far from meeting the requirements of quality standards. Backward production technology and poor coordination of parts and components. Poor technology and rough appearance.

The main reasons for this are: cutting corners and not hesitate to use inferior materials. Barely produce without basic production conditions and technology. Poor quality awareness and lack of strict management. Illegal operation and unscrupulous means to seek benefits. The management is chaotic, resulting in the decline of product quality. For the vital interests of the majority of consumers, in order to crack down on and prevent the sale of unqualified products in the market, in addition to the strict monitoring of relevant government departments, dealers should cooperate closely with the majority of consumers to resist inferior goods.

Therefore, our company has set up a special "lock common sense column" to introduce the basic common sense of locks to consumers, so that consumers can have a basic understanding of locks and increase their understanding and understanding of locks. Special attention should be paid to the selection, installation and use of locks, so as to educate and guide consumers and drive inferior products out of the market.

The following is the common sense of publishing locks, hoping to benefit readers.

Classification of locks

With the progress of the times, locks have developed rapidly. There has been a leap in shape, surface treatment, structure, function and material application. Various professional locks came into being. Styles and varieties emerge one after another, so that locks occupy an extremely important position in the hardware products and security products industry. Taking the commonly used mechanical lock with marble structure as an example, the locks are generally classified and explained only according to the application occasion.

A. Locks for buildings locks for buildings refer to the locks used on the doors of buildings, which can be basically divided into four categories.

1、 External door lock - a lock whose lock body is installed on the surface of the door lifter.

It is generally applicable to the outer door of the building, the outer door or hall door of each residence. Its varieties include single tongue lock, double tongue lock (or multi tongue lock) and double buckle lock (commonly known as tiger lock). Single tongue, double tongue or multi tongue are generally horizontal during movement; The double button (tiger) lock has a vertical lock tongue when moving.

The lock head structure of external lock is generally divided into single lock head and double lock head. The main differences between them are:

1. Single lock head: open the door with a key and the door with a handle (or knob). The utility model has the advantages of strong confidentiality outside the door, convenient operation inside the door and no key. It is especially suitable for fire prevention and other emergencies. But the drawback is that as long as someone is inside the door (including thieves), the door can be opened at any time.

2. Double lock head: both the door and the door are opened with a key. Its confidentiality is higher than that of a single lock head. Thieves can't open without a key. In addition, most of them also have defense function. As long as there is no key to retract the lock tongue, the lock can't be removed with general tools, such as screwdriver, pliers and hammer. Unfortunately, there is no single lock for emergency operation (for example, it is difficult to escape in case of fire), which is easy to make mistakes in busy time, resulting in delay of time; In the double button (tiger) lock, because the lock tongue moves in a vertical direction, the lock tongue is generally cylindrical, and the extension or retraction of the lock tongue is generally carried out by using the key or knob (or handle). Therefore, the lock tongue structure has self-collision and non self-collision functions, and the gap between them is:

a. Self touch function: there is an inclined plane on the cylindrical lock tongue. As long as the lock body touches the lock buckle plate, the lock tongue will hook, commonly known as self touch. At this time, the door outside must be opened with a key, and the door inside can be locked or opened with a knob (or handle) or key; The self touch function lock body is generally equipped with a safety button. When it is necessary to cover the door without locking, the safety button must be locked so that the inclined tongue of the lock surface does not extend, and the door can be opened and closed freely. There is no key outside the door. It is impossible to open the door.

b. Non self touching function: there is no inclined plane on the cylindrical lock tongue. When the lock tongue is retracted, the door can be closed, and then the knob (or handle) or key can be used to lock it. When the lock tongue is extended, the door cannot be closed. Generally, the lock does not have a safety button, and the key is required to switch outside the door, and the knob (or handle) or key is used to switch inside the door.

II Spherical door lock - the lock body is inserted and installed in the door lifter, and the lock head and safety mechanism are set in the ball handle (handle).

It is generally applicable to the door in the house. It can be divided into cylindrical ball and three-bar ball, cylindrical handle and three-bar handle. The cylinder is different from the three rods in the structure of the lock body, and its use function is also different. The function of cylinder lock is to open it directly with the key. The three lever lock opens or closes the switch with the key, and then opens it with the handle or handle. In China, it is customary to use cylindrical type, while in foreign countries, it is more common to use three-bar type. It includes room lock, bathroom lock, channel lock, storage room lock, courtyard lock / balcony lock, classroom lock, emergency exit lock, one-way communication lock, two-way communication lock, hotel lock, Hotel President lock, single head fixed lock, double head fixed lock, sleeve lock, etc.

III Mortise door lock - the lock body is inserted and installed in the door lifter, and its handle cover plate is assembled on the surface of the door lifter.

Because of its good anti-theft performance, it is suitable for use on the outer door of the house. (but it can also be installed on the inner door according to the actual situation) it is especially suitable for people with disabilities, including unilateral tongue, oblique tongue, double tongue, multi tongue, multi tongue linkage, etc. Definition of latch linkage: in addition to completing its own function, it uses connecting rod or other methods to move other parts. For example, the marble core-inserted door lock or external double tongue door lock, the lock head is the opening and closing square tongue, and the handle is the opening and closing oblique tongue. However, if there is a linkage mechanism, it can open and close the square tongue, and open and close the oblique tongue at the same time, while the handle remains separate to open and close the handle; In addition, up-down linkage or up, middle and down linkage (such as multi-point locking) belong to the category of linkage.

IV Sliding door lock - a lock whose latch is generally in the shape of a hook to fasten the door frame.

It is generally suitable for push-pull metal doors, gates and wooden doors, including pull lock, roll lock, roll shutter lock, aluminum door lock, etc.

A. Industrial lock is suitable for locks in industrial engineering, such as electrical switch program lock, machine tool lock, instrument lock, electrical cabinet, box lock, etc.

B. Furniture lock is suitable for locks used on furniture, such as drawer lock, window lock, luggage lock, mailbox lock, etc.

C. Locks for vehicles are suitable for locks used on all kinds of vehicles and ships, such as bicycle locks, motorcycle locks, car locks, train locks, ship locks, aircraft locks, etc.

D. Special purpose lock a lock used in a special environment, such as prison lock, torture tool lock, fire lock, etc.
