a compound lock

Abstract

The invention discloses a compound lock, which comprises a lock case, a buckle, a buckle and an electric control trigger device respectively installed on the lock case. The device drives the buckle to swing, the lock buckle includes a first rotating part and a first extension part extended from the first rotating part, the buckle includes a second rotating part and a first extension part extended from the second rotating part The second extension part of the composite lock, the composite lock also includes a connection block, one end of the connection block is connected to the electric control trigger device, and the other end is connected to the second extension part, and the middle part of the connection block is rotatably connected to the lock housing . The invention makes the installation of the electric control trigger device more convenient, the installation position is more flexible, the structure is more stable, and the volume of the composite lock is reduced.

Description

technical field [0001] The invention relates to a lock, in particular to a composite lock. Background technique [0002] At present, motorcycle seat locks, electric vehicle seat locks, car trunk locks and door locks often use mechanical and electronic composite locks. The existing mechanical and electronic composite locks are opened by pushing or pulling the lower part of the buckle through an electronically controlled trigger device. The position and structure of each component of the lock body and the composite lock are fixed, the volume is large, the push-pull acceleration is large, and the work is unstable. In view of the above problems, the Chinese utility model patent with the authorized announcement number CN202359907U discloses a composite lock, which is connected to the electric control trigger device through the top plate extending from the lower hem of the buckle, so that the electronic control trigger device can be installed on the back of the lock case. Reduce ...

Problems solved by technology

In view of the above problems, the Chinese utility model patent with the authorized announcement number CN202359907U discloses a composite lock, which is connected to the electric control trigger device through the top plate extending from the lower hem of the buckle, so that the electronic control trigger device can be installed on the back of the lock case. Reduce the height of the lock case, but the installation position of the electronic control trigger device can only be installed on one side of the hem of the buckle, and the trigger shaft of the electric control trigger device must be relatively close to the hem of the buckle to push or pull the card To open the lock body by buckle, because the installation position of the electronically controlled touch device is limited, the area of ​​the lock case cannot be rationally utilized, making the composite lock bulky, which is not conducive to the installation and use of the composite lock
