[0002] Sliding doors are a common type of door and window, and the lock body is an important component of sliding doors. Most existing sliding doors use single-cylinder locks. Referring to the utility model patent with publication number CN218406979U and patent name "Anti-falling structure of a sliding lock", our company designed a single-cylinder lock to solve the problem of fork falling. However, with the development of the industry and practical application, it has been found that the existing single-cylinder locks are relatively large in size. At the same time, the existing single-cylinder locks all use a base and are installed on the sliding door using the base. However, after installation, the base is quite prominent and not aesthetically pleasing. Moreover, the current anti-falling structure is relatively simple. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] As shown in the attached figure, the present invention discloses a push-pull door lock drive structure, comprising an outer cover 1, a base 2, a sliding seat 3, a fork 4, and an anti-fall structure 5. The door lock is connected to and installed on the door leaf via the base 2. The outer cover 1 has an inner cavity, in which the base 2, the sliding seat 3, and the anti-fall structure 5 are all disposed. The outer cover 1 conceals other structures of the door lock. The outer cover 1 is fixedly connected to the sliding seat 3, the base 2 is slidably connected to the sliding seat 3, and the sliding seat 3 is connected to the anti-fall structure 5. The anti-fall structure 5 is disposed inside the base 2. The fork 4 is located at the lower part of the base 2 and connected to the anti-fall structure 5. The anti-fall structure 5 is mainly used to prevent the fork 4 from falling due to its own weight or external force. During installation, the base 2 is first installed on the door leaf, and then the outer cover 1 is placed on top. The outer cover 1 is screwed in from the outside using the set screws and pushes against the inner sliding seat 3 to achieve a fixed connection between the outer cover 1 and the sliding seat 3. Alternatively, the outer cover 1 and the sliding seat 3 can be connected directly using snap-fit ​​or other methods. The outer cover 1 is designed to conceal the sliding seat 3 and the base 2. After installation, the base 2 is not visible from the outside, achieving a more aesthetically pleasing effect without the base 2. The door lock is opened and closed by moving the outer cover 1, creating the illusion of the entire door lock "sliding" and improving the user experience. It also provides another structure to prevent the fork 4 from falling.

[0020] Specifically, the base 2 includes a bottom plate 21 and an outer plate 22 connected to each other. The sliding seat 3 is disposed on the bottom plate 21 and has a strip groove. The outer plate 22 is slidably disposed in the strip groove. The anti-fall structure 5 is disposed between the bottom plate 21 and the outer plate 22. The outer plate 22 is installed on the bottom plate 21. During installation, the sliding seat 3 is first placed on the bottom plate 21, and then the outer plate 22 is placed in the strip groove and fixedly connected to the outer plate 22 and the bottom plate 21. The outer plate 22 and the bottom plate 21 clamp the sliding seat 3. The length of the outer plate 22 is shorter than the length of the strip groove, so that the sliding seat 3 can slide in a limited way along the outer length direction. Then, the outer cover 1 is fixedly connected to the sliding seat 3 to form a door lock assembly.

[0021] Specifically, the anti-fall structure 5 includes an outer frame 51 and a connecting block 52. The outer frame 51 is connected to the sliding seat 3. The upper part of the connecting block 52 is slidably disposed within the outer frame 51, and the lower part protrudes from the outer frame 51 and is fixedly connected to the fork 4. A Y-shaped groove 520 is recessed on the upper side of the connecting block 52. A Y-shaped block 521 is movably disposed within the groove 520. A spring 522 is disposed between the Y-shaped block 521 and the groove 520. The spring 522 passes through the lower part of the Y-shaped block 521, and the lower part of the spring 522 abuts against the bottom of the groove 520, thereby keeping the Y-shaped block 521 in an upward-push-up state. A ball bearing 53 is disposed on the top of the Y-shaped block 521. The outer plate 22 is provided with a latch 220. The ball bearing 53 protrudes outside the outer frame 51 and abuts against the latch 220. Figure 5-6As shown, the cross-sectional shapes of the Y-shaped block 521 and the groove 520 correspond. The upper two sides of the groove 520 have flat surfaces, and the upper two sides of the Y-shaped block 521 also have flat surfaces. Since the fork 4 is fixed to the connecting block 52, when the fork 4 is subjected to external force, the fork 4 will be pushed to the right directly through the connecting block 52. Due to the cooperation between the ball 53 and the bayonet 220, the connecting block 52 is difficult to be pushed directly. The outer cover 1 is slid, and the sliding seat 3 drives the outer frame 51 to slide. While the outer frame 51 is sliding, it will push the connecting block 52 and the fork 4 to move. The synchronous push of the outer frame 51 will cause the ball 53 to disengage downward from the bayonet 220. Under the abutment of the outer plate 22, the ball 53 and the Y-shaped block 521 are placed in the groove 520. When the sliding seat 3 slides in the opposite direction, it drives the outer frame 51 to slide, thereby causing the connecting block 52 and the fork 4 to move to the left until the ball 53 cooperates with the bayonet 220 again. At this time, the fork 4 has returned to its original position. The outer frame 51 is provided with a connecting rod 511 connected to the sliding seat 3, and the outer plate 22 has clearance spaces on both sides for the connecting rod 511 to protrude.

[0022] Specifically, the sliding seat 3 is provided with a locking member 6, the locking member 6 is provided with a protruding rib 66, and the base plate 21 is provided with a movable groove 210 for the protruding rib 66 to slide. One end of the movable groove 210 is provided with a curved part. The locking member 6 can rotate on the sliding seat 3. It should be noted that the outer cover 1 is provided with a hole for the locking member 6 to be exposed. The movable groove 210 is in the shape of a "7", with one end being a curved part and the other end being a vertical part corresponding to the sliding direction of the sliding seat 3. When the protruding rib 66 abuts against one end of the curved part, the sliding seat 3 cannot slide. When the locking member 6 is turned so that the protruding rib 66 is placed in the vertical part, the sliding seat 3 is in a sliding state.

[0023] Specifically, the outer cover 1 has an opening 100, and the upper side of the base 2 has an identification block 222 corresponding to the opening 100. Preferably, two identification blocks 222 are provided, and the two identification blocks 222 can be distinguished by different colors or patterns, so as to facilitate people to distinguish the door lock status.

[0024] The above embodiments are preferred embodiments of this utility model. All structures similar to this utility model and equivalent changes thereof should fall within the protection scope of this utility model.
