Description

Technical Field

[0001] The utility model belongs to the technical field of locks, and particularly relates to a self-resetting interlock with an unlocking holding function. Background Art

[0002] In the lock industry, with the progress of technology and the increasing demand for safety and convenience by people, the design and manufacture of locks have also experienced remarkable development. However, although existing locks have made great progress in anti-prying, anti-drilling and other safety performances, there are still certain technical bottlenecks in terms of user experience, especially regarding the issues of "automatic re-locking" or "false unlocking".

[0003] Traditional locks generally adopt a spring mechanism to drive the lock tongue to achieve the locking function. This design has advantages in simplifying the lock structure and reducing the manufacturing cost, but at the same time, it also brings significant problems - namely the "automatic re-locking" phenomenon. When a user tries to open a lock, if the reset force of the spring cannot be completely overcome, or if the external force suddenly disappears during the unlocking process, the lock tongue will quickly reset under the action of the spring, resulting in the lock seemingly being unlocked but actually still in the locked state, that is, the so-called "false unlocking".

[0004] The "false unlocking" phenomenon not only brings great inconvenience to users, who need to try repeatedly to confirm whether the lock is really opened. To solve the above problems, although some improved locks have appeared on the market, such as reducing the occurrence of "false unlocking" by adding an unlocking confirmation mechanism, optimizing the spring mechanics design, etc., these solutions often have disadvantages such as complex structure, high manufacturing cost, and easy damage, and are difficult to be popularized and applied comprehensively. Content of the Utility Model

[0005] Aiming at the problems in the background art, the purpose of the utility model is to provide a self-resetting interlock with an unlocking holding function, including:

[0055] The self-locking position is the position where the self-locking member 5 is close to the second locking body 2, and the standby position is the position where the self-locking member 5 is away from the second locking body 2.

[0056] When locking, the first locking body 1 moves towards the second locking body 2, the first locking body 1 abuts against the locking portion 6 and drives the lock catch 4 to rotate towards the unlocking holding position. When the locking groove 3 moves to be opposite to the locking portion 6, the lock catch 4 rotates to the locking position by elastic force, and the locking portion 6 rotates into the locking groove 3 to lock the first locking body 1; at the same time, the first locking body 1 drives the self-locking member 5 to slide to the self-locking position;

[0057] When unlocking, the lock catch 4 is driven by an external force to rotate to the unlocking holding position, the locking portion 6 leaves the locking groove 3 to unlock, and the self-locking portion 7 rotates to cooperate with the self-locking cooperation portion to lock the lock catch 4 in the unlocking holding position; after the first locking body 1 moves away from the second locking body 2, the self-locking member 5 slides to the standby position by elastic force, the self-locking cooperation portion moves away from the self-locking portion 7, and the lock catch 4 rotates to the locking position by elastic force.

[0058] Further, the self-locking cooperation portion is an elastic buckle 10. When the self-locking portion 7 rotates to cooperate with the elastic buckle 10, the self-locking portion 7 abuts against the first side of the elastic buckle 10 and drives its elastic deformation, so that the self-locking portion 7 rotates to the second side of the elastic buckle 10; then the self-locking portion 7 abuts against the second side of the elastic buckle 10 by the elastic force of the torsion spring 8, and the force applied by the self-locking portion 7 to the elastic buckle 10 is less than the elastic force of the elastic buckle 10.

[0059] When the self-locking member 5 slides towards the standby position by the elastic force of the spring 9, the self-locking member 5 transmits the elastic force of the spring 9 to the self-locking portion 7 through the elastic buckle 10 to overcome the elastic force of the torsion spring 8 to drive the lock catch 4 to rotate and / or make the elastic buckle 10 elastically deform, so that the elastic buckle 10 is misaligned with the self-locking portion 7.

[0060] Preferably, a guiding portion is provided on the locking portion 6. When the first locking body 1 moves towards the second locking body 2, the first locking body 1 abuts against the guiding portion and drives the lock catch 4 to rotate towards the unlocking holding position through the guidance of the guiding portion. In this embodiment, the guiding portion is a guiding inclined surface 11.

[0061] The working process of the present invention will be further described below:

[0062] Refer to successively Figures 6 to 8, when locked, the first lock body 1 moves towards the second lock body 2. The first lock body 1 abuts against the guiding inclined surface 11 on the locking portion 6 and drives the lock catch 4 to rotate towards the unlocking holding position by overcoming the elastic force of the torsion spring 8 under the guidance of the guiding inclined surface 11. When the lock groove 3 moves to be opposite to the locking portion 6, the lock catch 4 rotates to the locking position by elastic force, and the locking portion 6 rotates into the lock groove 3 to lock the first lock body 1. During this process, the guiding inclined surface 11 always abuts against the first lock body and the lock catch 4 does not rotate to the unlocking holding position. At the same time, the first lock body 1 drives the self-locking member 5 to slide to the self-locking position by overcoming the elastic force of the spring 9.

[0063] Refer successively to Figure 9 、 10 、6. When unlocking, the lock catch 4 is rotated to the unlocking holding position by an external force to overcome the elastic force of the torsion spring 8. The locking portion 6 leaves the lock groove 3 to unlock, and the self-locking portion 7 rotates to cooperate with the self-locking mating portion to lock the lock catch 4 in the unlocking holding position. Specifically, the self-locking portion 7 first abuts against the first side of the elastic buckle 10 and drives it to elastically deform, so that the self-locking portion 7 rotates to the second side of the elastic buckle 10; then the self-locking portion 7 abuts against the second side of the elastic buckle 10 by the elastic force of the torsion spring 8, and the elastic buckle 10 blocks the self-locking portion 7 to hold the lock catch 4 in the unlocking holding position. After the first lock body 1 moves away from the second lock body 2, the self-locking member 5 slides towards the standby position by the elastic force of the spring 9. The self-locking member 5 transmits the elastic force of the spring 9 to the self-locking portion 7 through the elastic buckle 10 to overcome the elastic force of the torsion spring 8 to drive the lock catch 4 to rotate and / or cause the elastic buckle 10 to elastically deform, so that the elastic buckle 10 is misaligned with the self-locking portion 7, so that the self-locking portion 7 does not hinder the sliding of the self-locking member 5. Then the self-locking member 5 slides to the standby position, the elastic buckle 10 moves away from the self-locking portion 7, and the lock catch 4 rotates back to the locking position by the elastic force of the torsion spring 8.

[0064] When the present utility model is locked, it can be automatically locked by the first lock body 1 pushing the locking portion 6 without additional operation. When unlocking, the self-locking portion 7 cooperates with the elastic buckle 10 to lock the lock catch 4 in the unlocking holding position, so that not only can the unlocking state be maintained after unlocking, but also no manual continuous pressure needs to be maintained after unlocking, and there will be no "false unlocking" phenomenon. The entire unlocking and relocking process only requires the lock catch 4 to be toggled once, without the need for the user to continuously intervene or perform multiple operations.

[0065] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings, but the present utility model is not limited to the above embodiments. Even if various changes are made to the present utility model, if these changes fall within the scope of the claims of the present utility model and its equivalent technologies, they still fall within the protection scope of the present utility model.
