The mounting plate 1 is bolted to the left side of the housing 2, and the limiting frame 101 is fixedly connected to the upper part of the mounting plate 1. Cover plates 3 are bolted to the front and rear sides of the housing 2, respectively, sealing the inner cavity of the housing 2. Two guide rods 8 are fixedly connected to the upper right corner of the inner cavity of the housing 2, arranged front to back. A sliding plate 401 is slidably positioned between the two guide rods 8 via a sliding groove. A return spring 9 is sleeved on the outside of each guide rod 8. The left and right ends of the return spring 9 are respectively connected to the right end of the sliding plate 401 and the inner wall of the housing 2. The return spring 9 is a high-strength spring, capable of quickly... The auxiliary sliding plate 401 is reset. The left end of the sliding plate 401 is horizontally inserted into the interior of the limiting frame 101 and is fixedly connected to the lock tongue 4. The lock tongue 4 is horizontally inserted into the mounting plate 1 and forms a sliding fit with the mounting plate 1. The inner cavity height of the limiting frame 101 matches the overall height of the lock tongue 4, ensuring that the lock tongue 4 can slide accurately into the limiting frame 101 and achieve stable storage of the lock tongue 4. The lower part of the housing 2 is connected to the lock cylinder 14 by bolts. The upper part of the lock cylinder 14 is provided with a lock hole 13 through a bearing. The front and rear sides of the lock cylinder 14 and the lock hole 13 are exposed through two front and rear cover plates 3. The upper part of the rear cover plate 3 is provided with a fixing handle 15 through a bearing. The upper and lower parts of the mounting plate 1 are provided with fixing grooves 16. The fixing grooves 16 can be matched with mounting screws, and the mounting plate 1 is stably fixed to the door body by the screws.

[0020] like Figures 1-5 As shown, a drive assembly is provided between the front cover plate 3 and the sliding plate 401. The drive assembly includes a locking rod 5, a crank handle 6, and a push frame 7. The locking rod 5 is fixedly connected to the right end of the sliding plate 401. The crank handle 6 is rotatably provided on the upper part of the front cover plate 3 through a bearing. The rear part of the crank handle 6 extends into the interior of the housing 2, and the push frame 7 is fixedly connected to the rear part of the crank handle 6. The sliding plate 401 is embedded in the pre-reserved slot on the upper part of the push frame 7 and maintains sliding contact with the push frame 7. The locking rod 5 is located on the right side of the push frame 7 and maintains close contact with the push frame 7.

[0021] like Figures 3-5 As shown, a second driving assembly is provided between the housing 2 and the sliding plate 401. The second driving assembly includes a connecting plate 10, a connecting frame 11, and a connecting rod 12. The part of the left end of the sliding plate 401 that does not penetrate the limiting frame 101 is fixedly connected to the connecting plate 10. The lower end of the connecting plate 10 is fixedly connected to the connecting frame 11. The connecting rod 12 is fixedly connected to the lock hole 13. The upper end of the connecting rod 12 extends into the interior of the connecting frame 11. Initially, the upper end of the connecting rod 12 is tightly fitted to the inner left side wall of the connecting frame 11.

[0022] When in use, the user installs the lock body on the door, with the crank handle 6 located on the inside of the door and the fixed handle 15 located on the outside of the door. The latch 4 is inserted into the lock hole on the door frame to lock the door.

[0023] When it is necessary to unlock from the inside of the door, the user rotates the crank handle 6 clockwise (viewed from the front of the housing 2). The pusher 7 then rotates clockwise to press the latch 5, causing the latch 5 to move the sliding plate 401 to the right along the guide rod 8, compressing the return spring 9. As the sliding plate 401 moves to the right, the latch 4 slides into the limiting frame 101. When the right side wall of the latch 4 is blocked by the right side wall inside the limiting frame 101, the user feels rotational resistance when rotating the crank handle 6, indicating that the latch 4 has slid into the limiting frame 101. At this time, the door can be pushed to open the door frame. After exiting, the door can be pushed up to close the door frame. The return spring 9 then returns to its original state, pushing the sliding plate 401 to move the latch 4 to the left to reset, allowing the latch 4 to re-insert into the lock hole on the door frame, thus achieving automatic locking.

[0024] When unlocking from the outside of the door is required, the user inserts the key into the keyhole 13 and then rotates the key counterclockwise (viewed from the rear side of the housing 2 as the front). The keyhole 13 then drives the connecting rod 12 to rotate counterclockwise, causing the connecting rod 12 to contact the inner right side wall of the connecting frame 11 (see reference). Figure 3 and Figure 4 The connecting frame 11 is pressed, causing the connecting plate 10 to move to the right. The sliding plate 401 then moves the latch 4 to the right and slides into the limiting frame 101, thus unlocking the door from the outside. Then, the fixed handle 15 is held to push the door to open the door frame. The key is pulled out, and the return spring 9 returns to its original state. The sliding plate 401 is pushed to move the latch 4 to the left to reset and complete the locking. At the same time, the connecting plate 10 moves the connecting frame 11 to the left to reset. When the connecting frame 11 resets, the connecting rod 12 is pushed to rotate clockwise by a certain angle. At this time, the connecting rod 12 is still in contact with the inner right side wall of the connecting frame 11, reducing the operating stroke of the key rotation next time.
