A limit plate 9 is arranged above the bending plate 7. When the limit plate 9 limits the bending plate 7, the lower surface of the limit plate 9 and the upper surface of the bending plate 7 are in contact with each other, and an inclined block 10 is arranged on one side of the groove 24. The inclined surface of the inclined block 10 is inclined downward, and the inclined surface faces the side of the placement block 6. A push rod 25 is connected to one side of the inclined block 10, and a limiting mechanism for driving the limiting plate 9 to limit the baffle 8 is connected to one side of the fixed plate 4. A separating member for driving the inclined block 10 to move so that the baffle 8 and the limiting plate 9 are separated is connected on one side of the fixed plate 4.

Specifically, as shown in FIG. 2 , one side of the fixing frame 3 is connected to a decorative surface 2 by bolts, a circular hole is provided on the decorative surface 2 , and the lock body structure is packaged by the decorative surface 2 , wherein the circular hole is a key insertion hole.

Specifically, as shown in Figures 4 and 5, the separation member includes a slide bar 18, which is horizontally arranged and slidably connected to the fixed plate 4. One end of the slide bar 18 is connected to a connecting frame 24, and the connecting frame 24 is a U-shaped structure.

In summary, the combined anti-theft door provided by the present embodiment requires maintenance or overhaul of the anti-theft door lock cylinder 5 after long-term use to ensure smooth unlocking and use of the anti-theft door. When replacing the anti-theft door, only the lock cylinder 5 needs to be replaced, which improves the convenience of replacement and maintenance of the anti-theft door and reduces the replacement cost. Therefore, it is often favored by consumers. Since the anti-theft door lock cylinder 5 is connected to the lock body structure by bolts, the lock body structure of the anti-theft door needs to be dismantled to replace the anti-theft door lock cylinder 5, and then the lock body structure is dismantled, and then the lock cylinder 5 is removed for maintenance or replacement. The disassembly operation of the lock cylinder 5 is cumbersome and complicated. In addition, in order to achieve the anti-theft effect and the lock body structure has good connection stability, a variety of connection structures are usually set to realize the connection between the lock body and the anti-theft door. Therefore, the disassembly of the lock body is particularly difficult. Even under professional props, it is very easy to cause damage to the lock body structure, including scratches on the lock body surface and the anti-theft door surface.

By setting a special lock core 5 installation structure in the anti-theft door, the lock core 5 structure can be quickly disassembled and assembled. When the lock core 5 needs to be installed, it is only necessary to remove the decorative surface 2 structure and complete the assembly between the lock core 5 and the bending plate 7 to ensure that one end of the lock core 5 is placed in the docking groove 31, and ensure that one end of the connecting rod 26 connected to one end of the lock core 5 passes through the docking groove 31 and is threadedly connected to the inner stud 13 set on one side of the bending plate 7, and the nut 15 is threadedly connected at one end of the connecting rod 26 to strengthen the connection between the inner stud 13 and the connecting rod 26. At this time, the spring 14 is in a compressed state. At this time, one end of the lock core 5 is limited by the docking groove 31, and the middle part of the lock core 5 is limited by the groove 1 33, thereby ensuring the stability of the connection of the lock core 5, and then the lock core 5 and the bending plate 7 and other structures are sent into the lock body;

The lock body structure includes a structure connected between a fixed frame 3 and a fixed plate 4, a lock box structure is arranged outside the fixed frame 3 and the fixed plate 4, and a plurality of openings are opened outside the lock box;

When assembling the lock core 5, it is necessary to ensure that one end of the docking groove 31 of the bending plate 7 overlaps the placement block 6, and push the lock core 5 so that the bending plate 7 can push the push plate 17 to move, so that the spring 2 16 structure is compressed. At this time, the installer needs to control the telescopic cylinder 11 to retract;

In the initial stage, the telescopic end of the telescopic cylinder 11 pulls the slide tube 29 to slide in the vertical part of the L-shaped groove 12. At this time, the slide clamp 28 rises along the slide rail 36. Since the inclined block 10 structure is connected to one side of the slide bar 18, the inclined block 10 is driven to rise when the slide bar 18 rises. When the slide bar 18 rises to the maximum height, the inclined block 10 rises to the horizontal side of the groove 2 34, and then the slide tube 29 enters the horizontal part of the L-shaped groove 12. At this time, the slider 35 starts to slide along the slide bar 18. When the slide tube 29 moves, the slide rod 21 structure will slide on the L-shaped groove 12 synchronously;

When the slide tube 29 is in the vertical part of the L-shaped groove 12, the slide tube 29 and the slide rod 21 are on the same vertical plane, and the limit plate 9 is in a vertical state. When the slide rod 21 moves to the horizontal part of the L-shaped groove 12, the slide rod 21 and the slide tube 29 are on the same horizontal plane, and the limit plate 9 is in a horizontal state. One side of the limit plate 9 is a hook-shaped structure, which pushes the lock core 5 to make the baffle 8 move synchronously. When the limit plate 9 flips to the horizontal state, the lock core 5 is released. At this time, the spring 16 rebounds to make the baffle 8 and the limit plate 9 contact each other. At this time, the limit plate 9 can limit the baffle 8.

The limit plate 9 can be flipped to completely avoid the movement of structures such as the bending plate 7. When the baffle plate 8 structure is pushed, the inclined block 10 structure will rise in height through the control of the telescopic cylinder 11, so the inclined block 10 structure will not collide with the lower end of the baffle plate 8. When the limit plate 9 limits the baffle plate 8, the inclined block 10 is set on the horizontal side of the groove 2 34. The baffle plate 8 structure can be limited by relying on the limit plate 9, and the lock core 5 can be limited by the bending plate 7 connected to the baffle plate 8. Only the decorative surface 2 needs to be installed later.

When the lock core 5 needs to be replaced and repaired, the decorative surface 2 is removed, and the inclined block 10 is moved toward the second groove 34 by pushing the push rod 25. The inclined surface of the inclined block 10 is in contact with the inner side of the second groove 34, thereby driving the baffle 8 to drop in height. At this time, the limit plate 9 and the baffle 8 are separated from each other until the baffle 8 is free from the limit of the limit plate 9. At this time, the spring second 16 structure pushes the bending plate 7 to pop out, so that the lock core 5 is popped out together with the bending plate 7. At this time, the operator can easily remove the lock core 5 structure. When the lock core 5 is replaced or repaired, it is necessary to control the extension of the telescopic cylinder 11 to reset the limit structure of the lock core 5, which is convenient for subsequent assembly.

By using this lock core 5 installation method to replace the traditional bolt connection structure, the lock core 5 can ensure the stability of the connection while facilitating the replacement and maintenance of the lock core 5, greatly improving the convenience of installation of the lock core 5. When replacing or repairing, the lock core 5 structure can be ejected with one button. When installing, the lock core 5 structure is pressed, and the limit plate 9 is used to automatically limit the lock core 5 structure, which greatly improves the convenience of maintenance of the lock core 5 and solves the problem of difficulty in maintenance and disassembly of the lock body structure in the current anti-theft door.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
