Guangdong Famous Door Lock Industry Obtained Patent
Guangdong Famous Door Lock Industry Obtained Patent for "Noise Reduction Lock Body and Noise Reduction Lock"
On August 13, it was reported that according to the information of the China National Intellectual Property Administration, Guangdong Mingmen Lock Industry Co., Ltd. had obtained a patent entitled "Noise Reduction Lock Body and Noise Reduction Lock", with the authorization announcement No. CN223215069U. However, there was information error in the application date, and the normal announcement was earlier than the application. It is speculated that the application date here should be September 2023.
This patent belongs to the field of lock technology, and its noise reducing lock body includes a housing, a pull rod, a lock tongue, and a first buffer component. There is a locking tongue hole on one side of the shell, and the sliding rod is set inside the shell with an installation part. The locking tongue can extend and retract along the locking tongue hole on the rod to achieve opening and locking. The first buffer component is located at the installation part, close to or away from the side of the lock tongue hole, which can counteract the collision force between the lock tongue and the housing and absorb noise. There is a limit block inside the shell, and when the lock tongue extends and retracts, the first buffer piece is pressed against it, ensuring that there will be no loud noise caused by operation collision when the pull rod is pulled to open the lock, bringing a quieter experience to the use of the lock.
