[0015] Please see Figure 1-4This utility model provides a technical solution: a mobile cabinet door locking device, comprising: a cabinet body 1, wherein guide rails 2 are provided on both the upper and lower sides of the cabinet body 1, and a first door panel 3 and a second door panel 4 are provided on the surface of the guide rails 2, the first door panel 3 and the second door panel 4 are slidably connected to the guide rails 2 and are staggered, a locking tongue mechanism 5 is provided on the side of the first door panel 3 and the second door panel 4, and a locking buckle mechanism 6 is provided inside the cabinet body 1 at the corresponding position, the locking tongue mechanism 5 includes a mounting plate 8 and a fixing bolt 9 is provided inside the mounting plate 8, the mounting plate 8 is fixedly connected to the door panel by the fixing bolt 9, and an integrally formed locking mechanism is provided on the side of the mounting plate 8. The tongue body 10, the locking mechanism 6 includes a fixed plate 11 installed inside the cabinet 1, and a connecting shaft 12 is provided on the surface of the fixed plate 11. A movable frame 13 is provided on the surface of the connecting shaft 12, and a guide wheel 16 is provided on the inner side of the movable frame 13. Two sets of movable frames 13 are provided and arranged opposite to each other. A locking mechanism 7 is provided inside the first door panel, and the locking mechanism includes a groove 17 provided inside the first door panel. A rotating shaft 18 is provided inside the groove 17, and a movable plate 19 is provided on the surface of the rotating shaft 18. Guide rails 2 are provided on both the upper and lower sides inside the cabinet 1, and a first door panel 3 and a second door panel 4 are provided on the surface of the guide rails 2. The first door panel 3 and the second door panel 4 slide with the guide rails 2. The first door panel 3 and the second door panel 4 are staggered and connected. A latching mechanism 5 is provided on the side of both the first door panel 3 and the second door panel 4, and a locking mechanism 6 is provided inside the corresponding position of the cabinet body 1. The latching mechanism 5 includes a mounting plate 8, and a fixing bolt 9 is provided inside the mounting plate 8. The mounting plate 8 is fixedly connected to the door panel by the fixing bolt 9. An integrally formed tongue 10 is provided on the side of the mounting plate 8. The locking mechanism 6 includes a fixing plate 11 installed inside the cabinet body 1, and a connecting shaft 12 is provided on the surface of the fixing plate 11. A movable frame 13 is provided on the surface of the connecting shaft 12, and a guide wheel 16 is provided on the inner side of the movable frame 13. Two sets of movable frames 13 are provided and arranged opposite each other. Pulling the first door panel... The first door panel 3 and the second door panel 4 allow the tongue 10 to be inserted into the guide wheel 16 between the two sets of movable frames 13, which can achieve relative locking. Applying a certain force can open the cabinet door. When not in use, the cabinet door can also be closed securely. A locking mechanism 7 is provided inside the first door panel, and the locking mechanism includes a groove 17 provided inside the first door panel. A rotating shaft 18 is provided inside the groove 17, and a movable plate 19 is provided on the surface of the rotating shaft 18. After the first door panel and the second door panel are completely closed, the movable plate 19 is rotated to be located on the side of the second door panel 4, thereby locking the first door panel and the second door panel, ensuring stability during movement. Its structure is simple, the operation is convenient, and the stability and security of the cabinet door opening and closing are improved.

[0016] Further improvements, such as Figure 3As shown: Connecting columns 14 are fixedly installed between the movable frames 13, and spring columns 15 are fixedly connected between the connecting columns 14. The setting of spring columns 15 enhances the elastic connection between the movable frames 13, so that the movable frames 13 can return to their original position more smoothly during the opening and closing of the cabinet door, thereby improving the stability and durability of the locking mechanism.

[0017] Further improvements, such as Figure 3 As shown: The movable frame 13 is rotatably connected to the fixed plate 11 via the connecting shaft 12. The rotatable connection design allows the movable frame 13 to rotate flexibly, facilitating the insertion and removal of the tongue 10, thereby simplifying the opening and closing operation of the cabinet door.

[0018] Further improvements, such as Figure 3 As shown: The guide wheel 16 is rotatably connected to the movable frame 13. The rotatable connection between the guide wheel 16 and the movable frame 13 reduces the frictional resistance when the tongue 10 is inserted and pulled out, making the cabinet door open and close more smoothly.

[0019] Further improvements, such as Figure 4 As shown: The movable plate 19 is provided with an iron sheet 20 inside and a magnetic block 21 is provided at a corresponding position inside the groove 17. The arrangement of the magnetic block 21 and the iron sheet 20 can fix the movable plate 19 in the groove 17 when not in use.

[0020] Further improvements, such as Figure 1 As shown: The bottom of the cabinet 1 is provided with a moving mechanism, which includes a mounting bracket, moving wheels, a steering shaft and a self-locking mechanism. The moving mechanism enables the mobile cabinet to move easily between different areas, improving the flexibility of space utilization.

[0021] Working principle: During the sliding of the door panel, the locking tongue mechanism 5 moves together with the door panel. When the door panel is close to the fully closed position, the tongue 10 inserts into the corresponding locking mechanism 6 inside the cabinet 1. Because spring posts 15 are provided between the movable frames 13, the insertion of the tongue 10 compresses the spring posts 15 and slightly opens the movable frames 13. After the tongue 10 is fully inserted, the spring posts 15 return to their original shape, tightly clamping the tongue 10 into the movable frames 13, thus achieving initial locking of the cabinet door. At this time, applying a certain force will open the cabinet door, but when not in use, it ensures the cabinet door remains securely closed. After the first door panel 3 and the second door panel 4 are fully closed, the user rotates the movable plate 19 in the locking mechanism 7 inside the first door panel 3. The movable plate 19 rotates around the rotation axis 18, and when it rotates 90 degrees, it is firmly fixed to the side of the second door panel 4. In this way, the first and second door panels are tightly locked together by the movable plate 19 and cannot be opened independently. This dual locking mechanism ensures the stability and safety of the mobile cabinet during movement. Users can move the mobile cabinet between different areas by pushing or pulling the cabinet body 1 and using the moving mechanism set at the bottom of the cabinet body 1.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
