[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please refer to Figures 1 to 4. This utility model provides a technical solution: a lock with an anti-mislocking emergency unlocking function, including a shell assembly 1 and a lock body 2. A dust cover 3 is provided on one side of the lock body 2. A groove 4 is formed on the side of the lock body 2 away from the dust cover 3. Sliding grooves 5 are formed on the two inner walls of the groove 4. A locking tongue 6 is provided inside the groove 4. A first cavity 7 is formed on the inner side of the lock body 2 away from the groove 4. A sliding post 8 is provided at one end of the locking tongue 6. A positioning groove 9 is formed at the end of the sliding post 8 away from the locking tongue 6. A spring 10 is provided inside the positioning groove 9. Positioning plates 11 are provided on both sides of the sliding post 8. The interiors of the two positioning plates 11 are perforated with the sliding post 8. The two pull rods 12 are parallel to the column 8. One end of each pull rod 12 is provided with a stop plate 13, and the end of each pull rod 12 away from the stop plate 13 is provided with a pull plate 14. The two sides of the lock tongue 6 are provided with sliders 15. The bottom of the lock body 2 is provided with a fixed seat 16. The two ends of the fixed seat 16 are provided with second cavities 17. The two walls of the two second cavities 17 are provided with limit grooves 18. One end of the two second cavities 17 is connected to one end of the compression spring 19. The other end of the two compression springs 19 is provided with a pressure plate 20. The two ends of the two pressure plates 20 are provided with limit blocks 21. The side of the two pressure plates 20 away from the compression spring 19 is provided with a locking pin 22.

[0022] In this embodiment, as shown in FIG1, the outer shell assembly 1 includes a mounting base 101, a mounting groove 102 is provided at the top of the mounting base 101, and slots 103 are provided on the two inner walls of the mounting groove 102.

[0023] In this embodiment, as shown in Figure 4, the slot 103 and the pin 22 are designed with a snap-fit ​​structure to fix the position of the lock body 2 and prevent the lock body 2 from becoming loose or falling off during use.

[0024] In this embodiment, as shown in FIG1, the internal dimensions of the slide groove 5 are consistent with the external dimensions of the slider 15; this increases the stability of the locking tongue 6 during movement, thereby preventing the locking tongue 6 from shifting or tilting during movement.

[0025] In this embodiment, as shown in Figure 2, the sliding pin 8 and the lock body 2 are connected by a sliding connection; this enables the rapid unlocking of the bolt 6 after accidental locking, greatly improving the convenience of the lock during installation and solving the problem that the lock needs to be unlocked by professional personnel using unlocking equipment after accidental locking, thereby avoiding unnecessary unlocking costs.

[0026] In this embodiment, as shown in FIG4, the limiting groove 18 and the limiting block 21 are configured to slide; this increases the stability of the pressure plate 20 during movement, thereby preventing the pressure plate 20 from shifting during movement.

[0027] In this embodiment, as shown in Figure 3, the compression spring 19 and the pressure plate 20 are symmetrical about the vertical center line of the fixed seat 16 with respect to each other; this allows the lock body 2 to be quickly installed on the surface of the fixed seat 16, greatly improving the working efficiency of the lock body 2 during installation, thus meeting the requirements of locks with anti-mislocking and emergency unlocking functions.

[0028] The method of use and advantages of this utility model: When using this type of lock with anti-mislocking and emergency unlocking function, the working process is as follows:

[0029] As shown in Figures 1, 2, 3, and 4, the mounting base 101 is first fixed in the designated position. When the lock body 2 needs to be installed, the fixing base 16 is inserted into the mounting groove 102. At this time, the locking pin 22 is resisted by the inner wall of the mounting groove 102. The locking pin 22 drives the pressure plate 20 to move into the second cavity 17 under the cooperation of the limiting groove 18 and the limiting block 21. At the same time, the pressure plate 20 compresses the compression spring 19. When the locking pin 22 moves to the slot 103, the compression spring 19 uses its own elastic structure to drive the locking pin 22 to engage with the inside of the slot 103 under the cooperation of the limiting groove 18 and the limiting block 21 through the pressure plate 20. This creates a locking structure between the locking pin 22 and the slot 103, allowing the lock body 2 to be quickly installed on the surface of the fixing base 16, greatly improving the installation efficiency of the lock body 2. This improves the efficiency of the lock's operation, thus meeting the requirements of locks with anti-mislocking and emergency unlocking functions. When the lock is accidentally locked and needs to be opened, the dust cover 3 is opened, and then the pull plate 14 is pulled by the pull ring. At this time, the pull plate 14 drives the abutment plate 13 to move to one side of the first cavity 7 through the pull rod 12. At this time, the abutment plate 13 drives the sliding column 8 to move through the positioning plate 11, so that the sliding column 8 compresses the spring 10. At the same time, the sliding column 8 drives the bolt 6 to move to one side of the groove 4 with the cooperation of the sliding groove 5 and the slider 15, so that the bolt 6 disengages from the inside of the lock, realizing the rapid unlocking of the bolt 6 after mislocking. This greatly improves the convenience of the lock during installation, solves the problem that the lock needs to be unlocked by professional personnel using unlocking equipment after mislocking, and avoids unnecessary unlocking costs.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
