Description

Technical Field

[0001] This utility model relates to the field of locks, and in particular to a lock. Background Technology

[0002] Some existing cabinets or doors do not normally have locks and require additional locks to meet certain practical needs. However, mechanical locks that open with ordinary keys do not fully meet the actual needs of customers. Customers actually prefer door locks like combination locks, which can be unlocked without a key. However, existing combination locks, like traditional locks, use a lever and lever mechanism to unlock after the combination is deactivated. This unlocking method is not stable enough. Therefore, a lock with a simple structure, stable and efficient rotation, and greater durability is needed. Utility Model Content

[0003] The main purpose of this utility model is to provide a lock that is simple in structure, has stable and efficient rotation, and is more durable.

[0004] This utility model proposes a lock, including a first lock seat, a second lock seat and a connecting chain, one end of which is fixedly connected to the second lock seat;

[0005] The first lock base includes a first lock base housing, a password limiting component, a rotation unlocking component, a locking component, and a press unlocking component. A first lock base lock hole is provided on one side of the first lock base. The other end of the connecting chain can extend into the first lock base lock hole. The locking component is provided on the side of the first lock base lock hole inside the first lock base housing. One end of the locking component is provided with a locking pin that can pass through the first lock base lock hole to lock the connecting chain.

[0006] The locking member has a locking member connecting tooth on its top. The rotating unlocking member is rotatably connected to the first lock seat housing. The rotating unlocking member has an unlocking member connecting tooth on its top that matches the locking member connecting tooth. One end of the pressing unlocking member is located inside the first lock seat on one side of the rotating unlocking member, and the other end of the pressing unlocking member is located on the outside of the first lock seat. By pressing the pressing unlocking member, the locking member can be moved through the rotating unlocking member to achieve the functions of unlocking and locking.

[0007] The password limiting component is disposed on the other side of the rotating unlocking component, and the rotation of the rotating unlocking component is restricted by the password limiting component.

[0008] Preferably, the other end of the locking member is connected to the first return spring, which can drive the locking member to reset.

[0009] Preferably, the first lock seat housing includes a first lock seat base and a first lock seat top cover.
