[0006] When the box door is closed, one end of the rotating shaft spirally slides along the spiral guide mechanism, and the swing plate moves upward and rotates into the inner side of the guide frame.

[0007] Preferably, the spiral guide mechanism includes a fixed seat fixedly connected to one side of the front surface of the housing, a fixed shaft fixedly connected to the front surface of the fixed seat, a spiral blade fixedly connected to the outer surface of the fixed shaft, an end plate extending rearward fixedly connected to the upper end of the spiral blade, and a guide portion in contact with the spiral blade at one end of the rotating shaft.

[0008] Preferably, the two ends of the rotating shaft are respectively fixedly connected to upper sliding columns, the guide part includes a connecting column fixedly connected to the end of one side of the upper sliding column, one end of the connecting column is rotatably connected to a connecting block, one side surface of the connecting block is fixedly connected to a guide block, the end face of the guide block slides against the outer surface of the spiral blade, and the rear surface of the connecting block slides against the front surface of the door.

[0009] Preferably, a sliding column is fixedly connected to the lower end of each of the two sides of the swing plate, and a sliding opening is provided through each of the two sides of the guide frame. The upper sliding column is slidably inserted into the inner side of the sliding opening, and an inclined guide surface is provided on the lower front side of the sliding opening.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. After the box door is opened, the guide block is restricted by the spiral plate at the end, which achieves the function of vertically restricting the guide block. The rotating shaft and the connecting column are respectively attached to the surface of the guide frame, which achieves the function of restricting the upper sliding column and preventing the upper sliding column from swaying in both directions. The swing plate is supported by the inclined surface, so it is in an inclined state, which makes it convenient for maintenance personnel to temporarily place the recording board on the surface of the swing plate.

The dust accumulated at the bottom can be discharged from the bottom vent.

[0018] 3. After the cabinet door is closed, the swing plate blocks the opening, and the inner frame is attached to the surface of the swing plate to prevent gaps between the outer perimeter of the opening and the swing plate. Then, during cabinet operation, heat is dissipated through the vent. Due to the presence of the dust baffle, it has a certain dustproof effect, preventing dust from directly entering the cabinet and providing ventilation and dustproof effects.

[0019] 4. In this invention, after the door is opened, the infrared detector head detects the infrared radiation emitted by the human body, sends an electrical signal to the lighting module, controls the battery to supply power to the lighting unit, achieves the lighting effect, and assists the staff in performing maintenance operations.

[0031] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0032] like Figures 1-10 The distribution box shown includes a box body 1. A lighting mechanism is fixedly installed on the upper part of the front surface of the box body 1. A door 2 is rotatably installed on one side of the front surface of the box body 1. An opening 3 is opened on the front surface of the door 2. An inner frame 4 is fixedly connected to the edge of the opening 3. A guide frame 5 is opened on the front surface of the door 2 near the outer periphery of the opening 3. A rotating shaft 9 is slidably connected to the inner side of the guide frame 5. A swing plate 8 is fixedly connected to the lower surface of the rotating shaft 9. A plurality of ventilation holes 12 are opened on the front surface of the swing plate 8. An elastic grid mechanism is provided on the front surface of the swing plate 8. A spiral guide mechanism is provided on one side of the front surface of the door 2. A guide block 28 is fixedly connected to the front surface of the door 2 near the lower part of the opening 3. An inclined surface 29 is opened on the front surface of the guide block 28. The swing plate 8 contacts the surface of the inclined surface 29.

[0033] When the door 2 is closed, one end of the rotating shaft 9 slides upward along the spiral guide mechanism, and the swing plate 8 moves upward and rotates into the inner side of the guide frame 5.

[0034] like Figure 3 As shown, the spiral guide mechanism includes a fixed base 25 fixedly connected to one side of the front surface of the housing 1. A fixed shaft 24 is fixedly connected to the front surface of the fixed base 25, and a spiral blade 26 is fixedly connected to the outer surface of the fixed shaft 24. An end plate 27 extending rearward is fixedly connected to the upper end of the spiral blade 26. One end of the rotating shaft 9 is provided with a guide portion that contacts the spiral blade 26. The upper surface of the end plate 27 is horizontal. When the guide portion slides to the upper end, it will move horizontally along the upper surface of the end plate 27 and will not continue to move upward.

[0035] like Figure 4 , Figure 5 As shown, upper sliding columns 10 are fixedly connected to both ends of the rotating shaft 9. The guide part includes a connecting column 18 fixedly connected to one end of the upper sliding column 10. A connecting block 19 is rotatably connected to one end of the connecting column 18. A guide block 20 is fixedly connected to one side surface of the connecting block 19. The end face of the guide block 20 slides in contact with the outer surface of the spiral blade 26, and the rear surface of the connecting block 19 slides in contact with the front surface of the door 2. When the upper sliding column 10 slides upward, it rotates relative to the connecting column 18, which will rotate relative to the connecting block 19, preventing jamming. Because the end face of the guide block 20 slides in contact with the outer surface of the spiral blade 26, it can be ensured that the spiral rises along the surface of the spiral blade 26 when the guide block 20 rotates.

[0036] like Figure 6 , Figure 7 , Figure 8 As shown, sliding columns 11 are fixedly connected to the lower ends of the two sides of the swing plate 8, and sliding openings 6 are opened through the two sides of the guide frame 5. The upper sliding column 10 is slidably inserted into the inner side of the sliding opening 6. An inclined guide surface 7 is opened on the lower front side of the sliding opening 6. After the swing plate 8 slides up, the sliding column 11 slides into the inner side of the sliding opening 6 through the inclined guide surface 7. The opening of the inclined guide surface 7 ensures that the sliding column 11 can slide smoothly to the inner side of the sliding opening 6.

[0037] like Figure 2 , Figure 3 , Figure 4 As shown, a side opening 21 is provided on one side edge of the door 2. A mating seat 22 is fixedly connected to the upper and lower inner sides of the side opening 21, respectively. A mating post 23 is fixedly connected to the adjacent sides of the two mating seats 22. The mating post 23 is rotatably fitted onto the end face of the fixed shaft 24. When the door 2 rotates, the mating post 23 will rotate relative to the fixed shaft 24. The side opening 21 provides space to prevent it from scraping against the spiral blade 26.

[0038] like Figure 8 , Figure 9 , Figure 10As shown, the elastic grid mechanism includes a dust baffle 13 disposed in front of each vent 12. A connecting plate 14 is fixedly connected to the front surface of several dust baffles 13. Several springs 15 are fixedly connected to the upper surface of the rear surface of the connecting plate 14. The rear end of the springs 15 is fixedly connected to the front surface of the swing plate 8. The springs 15 provide elasticity and tension to the dust baffles 13, increasing the number and duration of vibrations of the connecting plate 14 after contact, thereby promoting the shaking off of dust from the surface of the dust baffles 13.

[0039] A plurality of guide posts 17 are fixedly connected to the rear surface of the connecting plate 14. A guide cylinder 16 is slidably sleeved at the rear end of the guide post 17, and the rear end of the guide cylinder 16 is fixedly connected to the front surface of the swing plate 8. When the connecting plate 14 moves, the guide posts 17 can slide relative to the guide cylinder 16 to ensure the stability of the connecting plate 14 during movement.

[0040] like Figure 1 , Figure 2 As shown, the lighting mechanism includes a lighting module 32 fixedly mounted on the front surface of the housing 1. A battery 33, an infrared detector 34, and a lighting assembly 35 are fixedly mounted on the front surface of the lighting module 32. The infrared detector 34 contains a pyroelectric element that detects changes in infrared radiation. When a person enters the sensing range, the change in infrared radiation is converted into an electrical signal, which is transmitted to the lighting module 32. The lighting module 32 then controls the power supply from the battery 33 to provide illumination, facilitating maintenance.

[0041] like Figure 1 As shown, a door lock 30 is embedded in the front surface of the door 2, and a locking claw 31 is fixedly sleeved on the front end of the door lock 30. After the door 2 is closed, the door lock 30 is rotated, causing the locking claw 31 to engage with the inner edge of the box body 1, thereby locking the door 2.

[0042] After the user opens the door 2, the end of the guide block 20 is restricted by the spiral plate 26, which achieves the function of vertically restricting the guide block 20. The rotating shaft 9 and the connecting column 18 are respectively attached to the surface of the guide frame 5, which achieves the function of restricting the upper sliding column 10 and preventing the upper sliding column 10 from swaying in both directions. The swing plate 8 is supported by the inclined surface 29, so it is in an inclined state, which makes it convenient for maintenance personnel to temporarily place the recording board on the surface of the swing plate 8, eliminating the inconvenience of the user holding it with one arm and recording with the other hand, freeing up both hands to facilitate maintenance and recording operations.

[0043] When the user places the recording board, he presses the connecting plate 14 and the dust baffle 13 and squeezes the spring 15. When the recording board is removed, the elasticity and tension of the spring 15 help the dust baffle 13 to shake back and forth, which helps the dust on the surface of the dust baffle 13 to fall off. The dust accumulated at the bottom can be discharged from the bottom vent 12.

[0044] During the closing process of the cabinet door 2, the guide block 20 will contact the spiral plate 26. Under the guidance of the spiral plate 26, it will spiral upward until it reaches the upper surface of the end plate 27 and stops. At this time, the cabinet door 2 is in a completely closed state. During this process, the upper sliding column 10 slides upward along the sliding opening 6. The lower edge of the swing plate 8 will contact the inclined surface 29. The swing plate 8 is still in an inclined state until it slides to the lower edge of the swing plate 8 and reaches the guide block 28. Under the action of gravity, the swing plate 8 is in a drooping state. The lower sliding column 11 slides into the inner side of the sliding opening 6 through the inclined guide surface 7. At this time, the swing plate 8 blocks the opening 3. The inner frame 4 is attached to the surface of the swing plate 8 to prevent the outer perimeter of the opening 3 from leaving a gap between the swing plate 8 and the outer perimeter of the opening 3. Afterwards, during the operation of the cabinet 1, heat is dissipated through the vent 12. Due to the presence of the dust baffle 13, it plays a certain role in dust prevention, preventing dust from directly entering the interior of the cabinet 1, and has the effect of ventilation and dust prevention.

[0045] When the door 2 is opened, the infrared detector 34 detects the infrared radiation emitted by the human body and sends an electrical signal to the lighting module 32, which controls the battery 33 to supply power to the lighting group 35 to achieve the lighting effect and assist the staff in performing maintenance operations.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention. The scope of protection claimed by the appended claims and their equivalents is defined.
