The front end of the cabinet body 2 is slidably connected to a plurality of closing plates 3, and these closing plates 3 can be opened or closed to provide access to the inside of the cabinet body 2, so as to facilitate the installation, maintenance and overhaul of the equipment. The front end of the closing plate 3 is slidably connected to a handle 4, and the handle 4 can conveniently open the closing plate 3. Limiting blocks 5 are fixedly connected to both sides of the rear end of the handle 4, and these limiting blocks 5 can limit the movement range of the handle 4.

[0034] Springs 6 are sleeved on the outside of both sides of the rear end of the handle 4, and the far sides of the two limiting blocks 5 are rotatably connected to the rotating rod 7. The handle 4 can drive the limiting block to move 5, so that the limiting block 5 drives the rotating rod 7 to rotate, and the end of the rotating rod 7 away from the limiting block 5 is rotatably connected to the sliding rod 8, so that the sliding rod 8 is driven by the rotating rod 7, and the outer side of the sliding rod 8 is slidably connected to the inner wall of the closing plate 3, so that the sliding rod 8 can slide stably, and the other end of the sliding rod 8 is fixedly connected to the card block 9, and the movement of the sliding rod 8 can drive the card block 9 to move.

[0035] Slide grooves 10 are provided on the inside of both sides of the closing plate 3, and the outside of the limiting block 5 is slidably connected to the inner wall of the slide groove 10, so that the limiting block 5 is restricted. One end of a spring 6 is fixedly connected to one side of the limiting block 5, and the other end of the spring 6 is fixedly connected to the inner wall of one side of the slide groove 10. This design enables the handle 4 to automatically return to its original position after being released, thereby improving the convenience of operation. A number of card grooves 11 are provided on the inner walls of both sides of the cabinet 2, and the outside of the card block 9 is engaged with the inner wall of the card groove 11, so that the card block 9 can extend into the inner wall of the card groove 11, thereby locking the closing plate 3. An extension plate 12 is fixedly connected to the bottom of the rear end of the closing plate 3, and a plurality of slots are arranged on the outside of the extension plate 12, and grooves are provided on the inside of both sides of the extension plate 12.

[0036] refer to Figure 1 , Figure 4 and Figure 5 A limiting component is provided inside the groove, which can help fix and limit the position of electrical equipment and lines to prevent them from sliding or moving inside the distribution cabinet. The limiting component includes a spring 13, which is provided inside the groove. A sliding block 14 is slidably connected to the inner wall of the groove. One end of the spring 13 is fixedly connected to one side of the groove, and the other end of the spring 13 is fixedly connected to one side of the sliding block 14. This design allows the sliding block 14 to automatically return to its original position under the action of the spring 13, thereby improving the convenience of operation. A sliding column 15 is fixedly connected to the outer wall of the sliding block 14, and the outer side of the sliding column 15 is slidably connected to the outside of the extension plate 12, so that the sliding column 15 can be telescopic. The other ends of the two sliding columns 15 are fixedly connected to a limiting frame 16, and the outer side wall of the limiting frame 16 is in contact with the inner side wall of the cabinet 2. The limiting frame 16 can limit the wires and can It can automatically adjust to the thickness of the wire. Fans 17 are fixedly connected to the inner walls of both sides of the ventilation box 1. The adjacent sides of the two fans 17 are fixedly connected to the air inlet duct 18. By starting the fan 17, the external air can be sucked into the air inlet duct 18. The external top of the air inlet duct 18 is fixedly connected to the bottom of the cabinet 2, so that the air can enter the cabinet 2 through the air inlet duct 18. Dust-proof nets 19 are fixedly connected to both sides of the ventilation box 1. The dust-proof net 19 prevents dust from entering the equipment. A ventilation duct 20 is fixedly connected to the top of the cabinet 2. The ventilation duct 20 can maintain air circulation, so that the inside of the equipment remains dry. A dust-proof net 21 is fixedly connected to the inner wall of the ventilation duct 20 to prevent dust from entering the equipment. The front bottom of the ventilation box 1 is rotatably connected to an inspection door 22, and the inspection door 22 is fixed to the front end of the ventilation box 1 by screws, which is convenient for disassembly to carry out inspection and maintenance.

[0037] Working principle: When the device is in normal use, the fan 17 is started, and the external air is drawn into the ventilation box 1 through the dustproof net 19. At this time, the air will enter the cabinet 2 along the air inlet pipe 18, and then pass through the slots of the extension plate 12, and finally go out through the ventilation pipe 20, which can dissipate the heat of the device while keeping the device dry to prevent moisture from affecting the device.

[0038] When the cabinet 2 needs to be opened, it is only necessary to pull the handle 4, and the limiting block 5 can be moved when the handle 4 is pulled. At this time, the movement of the limiting block 5 can drive the rotating rod 7 to rotate, and the rotation of the rotating rod 7 can drive the sliding rod 8 to move, and the movement of the sliding rod 8 can drive the block 9 to move, so that the closing plate 3 can be driven by pulling the handle 4 to make the extension plate 12 slide out of the inner wall of the cabinet 2. In the process of inserting the extension plate 12 back, the block 9 will resist the cabinet 2, causing the block 9 to push the sliding rod 8, so that The sliding rod 8 drives the rotating rod 7 to rotate. At this time, the rotating rod 7 pushes the limiting block 5 to move the handle 4 and squeeze the spring 6. When the extension plate 12 completely enters the interior of the cabinet 2, the block 9 will coincide with the slot 11. At this time, the spring 6 will rebound to reset the limiting block 5, thereby driving the rotating rod 7 to rotate under the reset of the limiting block 5, so that the rotating rod 7 pulls the sliding rod 8 to drive the block 9 to engage with the inner wall of the slot 11, thereby completing self-locking and avoiding falling out when not in use, thereby improving the safety of the equipment.

[0039] The wires of the equipment inside the cabinet 2 can be restricted between the limiting frame 16 and the inner wall of the cabinet 2, and the limiting frame 16 can change the distance between the extension plate 12 through the sliding column 15 and the sliding block 14, so that the distance between the limiting frame 16 and the cabinet 2 can be changed. During the process, the spring 13 will store elastic potential energy to ensure that the limiting frame 16 can resist the wires and restrict the wires.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
