Description

Lock body main tongue fixing mechanism

Technical Field

The utility model relates to the technical field of intelligent door locks, in particular to a main tongue fixing mechanism of a lock body.

Background

The intelligent door lock is an improved lockset based on the traditional mechanical lock, and is more intelligent and simplified in the aspects of user safety, identification and manageability. The intelligent door lock is an executive component for locking the door in an access control system. The intelligent door lock is different from the traditional mechanical lock, and has the advantages of higher safety, convenience and advanced technology. The existing intelligent door lock is unlocked mainly through fingerprints, passwords and induction cards, and after the internal chip is processed, the control motor drives the driven piece to unlock.

The main bolt limiting and fixing mechanism of the intelligent lock body in the current market is a variable spring, the spring has different resistances to the bolt mechanism when the bolt mechanism moves at different positions, and the spring is driven by a motor with higher horsepower to drive the bolt mechanism to normally move, so that the efficiency of a battery is low, and the key or the handle is used for opening and closing the lock. Meanwhile, the spring can rust after long-time use, so that the resistance becomes larger, and the spring can drop or the main tongue mechanism of the card machine can be worn. Meanwhile, when the spring is in a completely unlocking or locking state, the resistance to the main tongue mechanism becomes very small, the main tongue mechanism cannot be fixed, the condition that the main tongue is not unlocked in place is often caused, the outermost end of the main tongue cannot be retracted into the guide piece of the lock body, and the door cannot be opened under the condition that the gap between the door and the door frame is small, so that the room for improvement is still reserved.

The utility model provides a lock body main tongue fixing mechanism, as shown in fig. 1 and 2, comprising: the lock comprises a lock shell 1, a main tongue component 2, a first magnetic attraction block 3, a second magnetic attraction block 4 and a magnetic attraction plate 5; a yielding hole 6 correspondingly adapted to the main tongue component 2 is formed in the lock shell 1; the main tongue component 2 is arranged in the lock shell 1; the first magnetic attraction block 3 is arranged on one side of the main tongue component 2; the second magnetic attraction block 4 is arranged on the other side of the main tongue component 2; the magnetic attraction plate 5 is arranged in the lock shell 1 and is positioned on one side of the main tongue component 2. In practical application, the magnetic attraction plate 5 is a metal plate capable of being attracted by the magnetic attraction block; the main tongue component 2 is pushed by a motor or a manual mechanism and moves to a corresponding position for completely unlocking or locking, wherein, as the two sides of the main tongue component 2 are respectively provided with the first magnetic attraction block 3 and the second magnetic attraction block 4, the main tongue component 2 only needs to separate the first magnetic attraction block 3 or the second magnetic attraction block 4 from the corresponding lock shell 1 or the magnetic attraction plate 5 under the action of external force, at the moment, the attraction force between the first magnetic attraction block 3 or the second magnetic attraction block 4 and the corresponding lock shell 1 or the magnetic attraction plate 5 is smaller, so that the main tongue component 2 can be moved without great external force, and after the main tongue component 2 moves to a specified position, the first magnetic attraction block 3 or the second magnetic attraction block 4 is attracted with the corresponding lock shell 1 or the magnetic attraction plate 5, thereby fixing the main tongue component 2, and as the attraction position of the first magnetic attraction block 3 and the second magnetic attraction block 4 is constant, the main tongue component 2 cannot be changed, thus the main tongue component 2 has higher stability.

Further, a connecting shaft 7 is provided on the lock case 1; one end of the connecting shaft 7 is fixed with the lock shell 1, and the other end is fixed with the magnetic attraction plate 5; a linear bearing 8 is arranged on the main tongue assembly 2; the linear bearing 8 is sleeved on the connecting shaft 7. In practical application, the linear bearing 8 is matched with the connecting shaft 7, so that the stability of the main tongue assembly 2 when sliding in the lock shell 1 can be improved.

Optionally, the main tongue assembly 2 comprises: a connecting frame 21 and a lock tongue 22; the lock tongue 22 is arranged at one end of the connecting frame 21; the linear bearing 8 is arranged on the connecting frame 21; the lock tongue 22 is in sliding connection with the abdication hole 6; the first magnetic attraction block 3 is arranged on one side of the connecting frame 21; the second magnetic attraction block 4 is arranged on the other side of the connecting frame 21. In practical application, the connecting frame 21 is acted by external force and slides on the connecting shaft 7 through the linear bearing 8, so that the lock tongue 22 penetrates or withdraws from the yielding hole 6.

Optionally, the connection frame 21 includes: a first mounting side plate 211, a second mounting side plate 212, and a connecting plate 213; the first mounting side plate 211 is disposed at one end of the connection plate 213; the second mounting side plate 212 is disposed at the other end of the connection plate 213; one end of the connecting shaft 7 is fixed to the first mounting side plate 211, and the other end is fixed to the second mounting side plate 212; the first magnetic attraction block 3 is arranged on the first installation side plate 211; the second magnetic attraction block 4 is arranged on the second installation side plate 212; a guide groove 9 is formed in the connecting plate 213; the guide groove 9 is L-shaped. In practical application, the first mounting side plate 211 corresponds to the magnetic attraction plate 5, the second mounting side plate 212 corresponds to the inner wall of the lock case 1, so that the first magnetic attraction block 3 and the magnetic attraction plate 5 are attracted to each other, and the second magnetic attraction block 4 and the inner wall of the lock case 1 are attracted to each other, and slide in the guide groove 9 through the connecting rod under the external action, so as to drive the connecting plate 213 to move, thereby unlocking or locking.

In the specific implementation process, when the door lock is unlocked, the motor or the manual mechanism pushes the main tongue component 2 to move inwards, and after the main tongue component 2 moves to the unlocking position, the first magnetic block 3 on the inner side can generate magnetic attraction with the magnetic plate 5 on the inner side, so that the main tongue component 2 does not have a movable gap. When the door lock is locked, the motor or the manual mechanism pushes the main tongue component 2 to move outwards, and after the main tongue component 2 moves to the locking position, the second magnetic attraction block 4 on the outer side can generate magnetic attraction with the lock shell 1 on the outer side, so that the main tongue component 2 does not have a movable gap. The main tongue component 2 is not hard connected with the lock shell 1 and the magnetic attraction plate 5, the functions and performances are not affected after abrasion and rust, the sudden resistance of the spring is not increased during displacement, the condition that a great force is needed during switching of the lock is caused, and the noise generated by the spring during displacement and deformation is not generated. After the door lock is opened and closed in place, the magnet can generate the strongest adsorption force, and the lock tongue 22 does not have the condition of position change.

The main tongue fixing mechanism of the lock body can improve the unlocking or locking stability of the main tongue mechanism.

The above description is only a preferred embodiment of the present utility model, and the protection scope of the present utility model is not limited to the above examples, and all technical solutions belonging to the concept of the present utility model belong to the protection scope of the present utility model.
