Description

Technical Field

[0001] The utility model belongs to the technical field of lock bodies, and in particular relates to a lock body that can be locked automatically. Background Art

[0002] Door locks, as a mechanism for controlling the opening and closing of doors, are frequently used. Currently, commonly used door locks typically consist of a lock body and a handle. When the user presses down or lifts the handle, the lock tongue in the lock body extends or retracts. The handle is then reset by a return mechanism within the lock body. However, this approach has certain limitations when used on sliding doors, making it inconvenient to use.

[0024] Further as Figure 1 、 Figure 2 and Figure 3 As shown, it is worth mentioning that the locking mechanism 3 includes a locking hook 301, which is arranged on the left side of the shell 1. The bottom of the locking hook 301 is fixedly connected to a connecting block 302 near the right part. The connecting block 302 is rotatably connected to a connecting shaft 303 and is fixedly connected to the shell 1. A matching lock 304 is arranged in the shell 1 on the left side of the locking hook 301. The locking hook 301 is made of stainless steel metal material.

[0025] By using stainless steel metal material, it is avoided that there is a conflict with the automatic locking mechanism 4, thereby improving the stability of the device during the automatic locking operation.

[0026] Further as Figure 2 、 Figure 3 and Figure 4 As shown, it is worth mentioning that the automatic locking mechanism 4 includes a first magnet 401, the first magnet 401 is fixedly installed in the connecting frame 2 and is arranged at the lower part of the lock buckle 304, the first magnet 401 is correspondingly provided with a second magnet 402 in the shell 1, and a limiting rod 403 is fixedly installed on the left side of the second magnet 402 on the inner side of the shell 1 for limiting the second magnet 402, the front side of the second magnet 402 is fixedly connected to a pushing block 409 and is arranged through the front side of the shell 1, the rear side of the second magnet 402 is fixedly connected to a slider 4010, the slider 4010 is correspondingly provided with a matching slide groove 4011 on the inner side of the shell 1, and the second magnet 402 is fixedly connected to the front side of the second magnet 402.

Two connecting plates 405 are provided on the upper part of the second magnet 402 and are symmetrically arranged front to back. The limiting slot 406 is an oblique slot arrangement, and the left side is higher than the right side.

[0027] When in use, the second magnet 402 and the first magnet 401 approach each other and repel each other, so that the second magnet 402 slides in the shell 1 through the slider 4010 and the slide rod 404. At the same time, with the movement of the connecting plate 405, the adjusting rod 407 is slid on the connecting plate 405 through the limiting groove 406, thereby driving the adjusting rod 407 to move through the limiting groove 406, and since the limiting groove 406 is set as an oblique groove, the adjusting rod 407 is squeezed, so that the adjusting rod 407 drives the fixing block 408 to move, so that the lock hook 301 rotates in the shell 1 through the connecting shaft 303, and then the lock hook 301 cooperates with the lock buckle 304 to form a lock, so that the sliding door is self-locked, realizing the automatic locking operation and improving the convenience of its locking operation.

[0028] This solution has the following working process: when this device is used, the housing 1 and the connecting frame 2 are respectively installed on the sliding door panel and the door frame through the mounting plate 101 and the mounting hole 102, and the sliding door is slid so that the housing 1 is close to the connecting frame 2. When the lock hook 301 is inserted into the connecting frame 2, the second magnet 402 and the first magnet 401 are close to each other and repel each other, so that the second magnet 402 slides in the housing 1 through the slider 4010 and the slide rod 404. At the same time, under the movement of the connecting plate 405, the adjusting rod 407 slides on the connecting plate 405 through the limiting groove 406, thereby driving the adjusting rod 407 through the limiting groove 406. 7 moves, and since the limiting groove 406 is set as an oblique groove, the adjusting rod 407 is squeezed, so that the adjusting rod 407 drives the fixing block 408 to move, so that the lock hook 301 rotates in the shell body 1 through the connecting shaft 303, and then the lock hook 301 cooperates with the lock buckle 304 to form a lock, so that the sliding door is self-locked, and an automatic locking operation is achieved. When it needs to be unlocked, the pushing block 409 is pushed to push the second magnet 402 into the shell body 1, so that the connecting plate 405 moves in the opposite direction, and then the first magnet 401 rotates in the opposite direction, thereby achieving an unlocking operation, thereby improving the convenience of its locking operation.

[0029] In summary: through the coordinated setting of the locking mechanism 3 and the automatic locking mechanism 4, when the lock body is locked, the shell 1 will be automatically locked when it is close to the connecting frame 2, so that the shell 1 and the connecting frame 2 can be connected together, thereby forming a lock. At the same time, the unlocking operation can also be achieved conveniently and quickly, thereby improving the ease of use of the device, and its structure is simple and easy to implement.
