[0002] A latch is an object used to fasten two items. Generally, it refers to a buckle-type fastener installed on doors and windows for locking them. It generally consists of a movable part and a fixed part, and the closing and opening of the doors and windows are achieved through the combination and separation of the movable part and the fixed part.

[0003] During the use of the latch, the existing movable parts all move by means of rotation or hinge, but the movable parts cannot be fixed, which makes it easy to open the latch during use. At the same time, most latches are used on doors and windows and are easily opened by children, which is relatively dangerous and not conducive to the use of the latch. Summary of the Utility Model

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0022] Embodiment: Refer to Figure 1-6 , the present invention provides a technical solution, a quick locking mechanism, including a first mounting plate 1 and a second mounting plate 2. One side of the first mounting plate 1 is lapped with a first base 3. One side of the first base 3 is threadedly installed with two groups of first bolts 21 and is symmetrically arranged, which is convenient for fixing the first bolts 21. One side of the first base 3 is fixedly installed with a connecting plate 4. One side of the connecting plate 4 is fixedly installed with a connecting column 5. One side of the connecting column 5 is rotatably installed with a rotating column 6. The surface of the rotating column 6 is fixedly installed with a rotating plate 7. One side of the rotating plate 7 is penetrated and provided with a hole 8. One side of the second mounting plate 2 is lapped with a second base 9. One side of the second base 9 is threadedly installed with four groups of second bolts 22 and is arranged in an array, which is convenient for fixing the second base 9. One side of the second base 9 is rotatably installed with a rotating cylinder 10. The surface of the rotating cylinder 10 is fixedly installed with two groups of limiting plates 11 and is symmetrically arranged. The inner wall of the rotating cylinder 10 is fixedly installed with a third mounting plate 12. The top of the third mounting plate 12 is provided with a cross slot 13. One side of the second base 9 is fixedly installed with an L-shaped plate 14. The top of the L-shaped plate 14 is installed with a cross plate 18 through a moving mechanism. The moving mechanism includes a threaded rod 15 rotatably installed on the top of the L-shaped plate 14. The surface of the threaded rod 15 is threadedly sleeved with a moving plate 16. One side of the moving plate 16 is fixedly installed with a fourth mounting plate 17. The bottom of the fourth mounting plate 17 and the top of the cross plate 18 are fixedly installed, which is convenient for driving the cross plate 18 to move. The inner wall of the cross slot 13 and the surface of the cross plate 18 are matched, and the inner wall of the hole 8 and the surface of the rotating cylinder 10 are matched.

[0023] Specifically, a limiting mechanism is provided on the inner wall of the L-shaped plate 14. The limiting mechanism includes a limiting groove 19 opened on the inner wall of the L-shaped plate 14. A limiting block 20 is slidably installed on the inner wall of the limiting groove 19. One side of the limiting block 20 is fixedly installed with one side of the moving plate 16, which limits the moving plate 16 and makes the movement of the moving plate 16 more stable. By rotating the threaded rod 15, the cross-shaped plate 18 is driven to rise, so that the cross-shaped plate 18 leaves the inner wall of the cross-shaped groove 13. Then, the rotating cylinder 10 can be rotated to drive the limiting plate 11 to reach the inner wall of the hole 8, and then the rotating plate 7 can be rotated to quickly open the lock. When the lock is needed, by rotating the rotating plate 7 to the side of the second base 9 and rotating the rotating cylinder 10 to drive the limiting plate 11 to rotate, the limiting plate 11 leaves the inner wall of the hole 8, which limits the rotating plate 7 and enables locking. By rotating the threaded rod 15 to drive the cross-shaped plate 18 to descend, so that the cross-shaped plate 18 reaches the inner wall of the cross-shaped groove 13, the third mounting plate 12 can be limited and installed, so that the position of the rotating cylinder 10 cannot be rotated and cannot be easily opened, further increasing the security of the lock. The structure is simple and convenient to use.

[0024] All the electrical components appearing in this article are electrically connected to the external main controller and 220V mains electricity, and the main controller can be a conventional known device such as a computer for control.

[0025] During use: When using this quick lock mechanism, when the lock needs to be opened, rotate the threaded rod 15 to drive the moving plate 16 to rise. The moving plate 16 drives the fourth mounting plate 17 to rise, and the fourth mounting plate 17 drives the cross-shaped plate 18 to rise, so that the cross-shaped plate 18 leaves the inner wall of the cross-shaped groove 13. Then, the rotating cylinder 10 can be rotated. The rotating cylinder 10 drives the limiting plate 11 to reach the inner wall of the hole 8, and then the rotating plate 7 can be rotated to quickly open the lock. When the lock is needed, by rotating the rotating plate 7 to the side of the second base 9 and rotating the rotating cylinder 10 to drive the limiting plate 11 to rotate, the limiting plate 11 leaves the inner wall of the hole 8, which limits the rotating plate 7 and enables locking. By rotating the threaded rod 15 to drive the moving plate 16 to descend, the moving plate 16 drives the fourth mounting plate 17 to descend, and the fourth mounting plate 17 drives the cross-shaped plate 18 to descend, so that the cross-shaped plate 18 reaches the inner wall of the cross-shaped groove 13, the third mounting plate 12 can be limited and installed, so that the position of the rotating cylinder 10 cannot be rotated and cannot be easily opened, further increasing the security of the lock. The structure is simple and convenient to use.
