[0003] After retrieval, the invention with the application number CN202010453094.3: a high-voltage and low-voltage electrical equipment with a ventilated and moisture-proof structure, when the user wants to overhaul the circuit board, the substrate can drive the circuit board to open at a certain angle, increasing the When the circuit board is pulled out, the space between the two circuit boards brings convenience to the user's operation... But there are also some shortcomings: for example, when the circuit board is overhauled, it is still necessary to enter the inside of the device body to repair the circuit board. After pulling out the maintenance, the maintenance process is more troublesome, and there are certain safety hazards; by using the moisture absorption board to absorb the moisture inside the equipment body, when the moisture absorption board absorbs moisture on the surface, it will slow down the moisture absorption board and the air. The moisture absorption rate and effect of the contact part, and the moisture-absorbing board cannot be reused well, which increases the cost of use

[0030] refer to Figure 1-Figure 3 , a ventilation and moisture-proof type high and low voltage electrical equipment, including a device body 1 and a plurality of circuit boards 16, and a quick inspection mechanism is arranged in the device body 1;

[0031] The quick inspection mechanism includes a convex hole 6 set on the side wall of the device body 1, a door panel 4 is connected to the convex hole 6, and a slider 5 is connected to the side wall of the door panel 4 for symmetrical rotation, and the slider 5 is slidably connected to the convex hole 6. The inner wall, the inner wall of the equipment body 1 is fixed with a semi-square tube 7, and the semi-square tube 7 is connected with a screw 11 for rotation, and the screw 11 is threaded with a nut 8, and the side wall of the nut 8 is connected with a first connecting rod 9 for rotation. The connecting rod 9 is rotatably connected to the door panel 4, the top of the convex hole 6 is rotatably connected to a second connecting ...

Embodiment 2

[0041] refer to Figure 4-Figure 6 , the difference between this embodiment and embodiment one is:

[0042] The top wall of the door panel 4 is provided with a vertical groove 27, the inner wall of the groove 27 is elastically connected with a push rod 28 by a conductive spring 30, the side wall of the push rod 28 is provided with a slot 29, and the inner wall of the door panel 4 is provided with a horizontal L-shaped Slot 26, the inner wall of the L-shaped groove 26 is elastically connected with an L-shaped plate 25 through the second spring 2, the inner wall of the L-shaped plate 25 is fixedly connected with a block, and the block is fixed in the slot 29, and the inner wall of the top of the device body 1 is fixedly connected with a The impact block 31, the L-shaped plate 25 is slidably connected in the L-shaped groove 26. In the later stage of the door panel 4 movement, the L-shaped plate 25 provided in the door panel 4 will be offset against the impact block 31, so that th...

Embodiment 3

[0046] refer to Figure 7-Figure 8 , the difference between this embodiment and embodiment two is:

[0047] The top wall of the screen box 23 is provided with a through hole connecting up and down, the inner wall of the through hole is fixedly connected with a toothed belt 32, and the bottom walls of the two vertical plates of the slab 13 are rotatably connected with a rotating rod 33, and the side walls of the rotating rod 33 are fixedly connected. There is a gear 34, the gear 34 is meshed with the toothed belt 32, and the bottom side wall of the rotating rod 33 is fixedly connected with a plurality of stirring plates 35. The silica gel particles 36 are accumulated in piles in the screen box 23, and the gear 34 drives the rotating rod 33 to rotate. Thus, the rotation of the rotating rod 33 drives the stirring plate 35 to stir the silica gel particles 36 .

[0048] In this embodiment, in the process of the movement of the shaped plate 13, it will drive the rotating rod 33 to ...
