[0016] The magnet rod is made of neodymium iron boron.

[0017] This utility model has the following beneficial effects:

[0018] 1. In this utility model, by pushing the handle, the cabinet door body is rotated and closed along the hinge. After the cabinet door body is closed, the electromagnet is energized, and the magnetic rod slides inside the through hole to the lower part of the electromagnet under the action of magnetic force. The magnetic rod is limited by the cooperation of the sliding block and the limiting groove, thereby realizing the self-locking structure of the low-voltage distribution cabinet door and improving the safety of the low-voltage distribution cabinet.

[0025] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-3 This utility model provides an embodiment of a self-locking low-voltage distribution cabinet door structure, including a door frame body 1. Hinges 2 are fixedly connected to the upper and lower left front sides of the door frame body 1. A cabinet door body 3 is rotatably connected to the door frame body 1 via the hinges 2. A handle 4 is fixedly connected to the right front side of the cabinet door body 3. An electromagnet 5 is fixedly connected to the upper middle part of the door frame body 1. A mounting groove 6 is provided on the upper part of the cabinet door body 3. A self-locking component is provided inside the mounting groove 6 for self-locking of the distribution cabinet door. The self-locking component includes a mounting block 9, which is slidably connected inside the mounting groove 6. Magnets 10 are fixedly connected to the upper left and right sides of the mounting block 9. Sliding blocks 8 are fixedly connected to the middle of the left and right sides of the mounting block 9. Limiting grooves 7 are provided on the left and right sides of the mounting groove 6. Sliding blocks 8 are slidably connected inside the limiting grooves 7. Through holes are provided on the upper middle left and right sides of both the door frame body 1 and the cabinet door body 3, and magnets 10 are slidably connected inside the through holes.

[0027] When the low-voltage distribution cabinet door needs to be self-locked, first push the handle 4 to make the cabinet door body 3 rotate along the hinge 2 and finally close the cabinet door body 3. Control the electromagnet 5 to be energized so that the magnetic force generated by the electromagnet 5 drives the magnet rod 10 to slide inside the through hole and move to the lower part of the electromagnet 5. The magnet rod 10 is limited by the cooperation of the sliding block 8 and the limiting groove 7, thereby effectively realizing the self-locking function of the cabinet door. This makes it easy for the cabinet door of the low-voltage distribution cabinet to be automatically locked, improves the safety of the cabinet door, and prevents the cabinet door from being accidentally opened due to improper human operation or external interference.

[0028] Reference Figures 1-3 The cabinet door body 3 is made of aluminum alloy, the sliding block 8 is made of polytetrafluoroethylene, the mounting block 9 is made of nylon, and the magnet rod 10 is made of neodymium iron boron.

[0029] The use of aluminum alloy ensures the strength of the cabinet door body 3, the use of polytetrafluoroethylene provides good sliding performance and wear resistance for the sliding block 8, the use of nylon provides good wear resistance and corrosion resistance for the mounting block 9, thereby improving the service life of the low-voltage distribution cabinet door structure, and the use of neodymium iron boron provides high magnetic force and strong corrosion resistance for the magnet rod 10.

[0030] Working principle: When it is necessary to self-lock the cabinet door of the low-voltage distribution cabinet, push the handle 4 to drive the cabinet door body 3 to rotate and close along the hinge 2. After the cabinet door body 3 is closed, control the electromagnet 5 to be energized so that the magnetic rod 10 slides inside the through hole to the lower part of the electromagnet 5 under the action of magnetic force. The sliding block 8 cooperates with the limiting groove 7 to limit the magnetic rod 10, thereby realizing the self-locking structure of the low-voltage distribution cabinet door and improving the safety of the low-voltage distribution cabinet.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
