[0015] Beneficial effects of the utility model:

[0016] 1. The sealing component can effectively seal the gap between the bottom box and the inspection cover, and at the same time, it can also enable the structure to be used for a long time, so that the structure can protect the inside of the electronic product from the invasion of water and moisture for a long time, and improve the waterproof performance of the electronic product.

At this time, by squeezing the gas delivery ball, the gas is inflated to the inside of the airbag. At this time, the airbag will squeeze the upper spring card and the lower spring card, and then use the elastic force of the spring sheet to make the two sides of the spring sheet close to the inside of the U-shaped groove and the lower card box, so that the joint is blocked, thereby avoiding the problem of external water entering the inside of the bottom box from the joint. At the same time, by fixing the upper spring card and the lower spring card to the outside of the airbag, when connecting, only the spring sheet will be contacted, avoiding the traditional use of silicone rings for blocking, thereby causing wear problems. At the same time, by setting the material of the spring sheet to a flexible steel plate material, it is convenient for the extrusion of the airbag and prolongs the service life of the sealing component.

[0017] 2. The waterproof component can be set up to stabilize and fix the bottom box and the inspection cover for connection, and at the same time prevent external water from entering the bottom box through the screws. When fixing, pass the bolt thread through the inside of the inspection cover and connect it with the inside of the top of the conical tube. At this time, the bottom of the bolt will be fixed to the top of the inside of the conical tube. After that, when water flows into the top of the bolt, the water will flow downward along the bolt. When the water flows to the hole inside the bolt, the water will flow from the hole at the bottom of the bolt to the inside of the conical tube. At this time, the water will flow out from the bottom of the bottom box along the outlet pipe, thereby avoiding the problem of water entering the inside of the bottom box, thereby promoting the screw to play a waterproof role.

The interior of the bottom box 1 and the inspection cover 2 is also provided with a waterproof component for waterproofing the screws. The waterproof component includes a bolt 19, a fixed cylinder 20, a straight cylinder 21 and a conical cylinder 24. The inside of the four corners of the top of the inspection cover 2 is provided with threaded holes, and the internal threads of the threaded holes are connected with bolts 19. The four corners of the upper spring card 6 are fixedly connected with the fixed cylinder 20, the interior of the top of the fixed cylinder 20 is fixedly connected with the straight cylinder 21, and the interior of the top of the straight cylinder 21 is slidably connected with the conical cylinder 24.

[0028] By setting up the sealing component, the gap between the bottom box 1 and the inspection cover 2 can be effectively sealed, and at the same time, the structure can be used for a long time, so that the structure can protect the interior of the electronic product from the invasion of water and moisture for a long time, and improve the waterproof performance of the electronic product. When in use, the U-shaped groove 11 is inserted into the top of the upper spring clip 6, so that the inspection cover 2 is connected to the bottom box 1. At this time, by squeezing the ball 8, the gas is prompted to inflate the interior of the airbag 5. At this time, the airbag 5 will squeeze the upper spring clip 6 and the lower spring clip 4, and then use the elastic force of the spring sheet to prompt the two sides of the spring sheet to be close to the U-shaped groove 11 and the interior of the lower card box 3, so that the joint is blocked, thereby avoiding the problem of external water entering the interior of the bottom box 1 from the joint. At the same time, by fixing the upper spring clip 6 and the lower spring clip 4 to the outside of the airbag 5, when connected, only the spring sheet will be contacted, avoiding the traditional use of silicone rings for clogging, thereby causing wear problems.

The shape of the upper spring clip 6 and the material of the upper spring clip 6 and the lower spring clip 4 are set as flexible steel plates, which not only facilitates the extrusion of the airbag 5, but also prolongs the service life of the sealing component. At the same time, the air delivery ball 8 and the knob 10 are set. The function of the air delivery ball 8 is to inflate the interior of the airbag 5, thereby facilitating the airbag 5 to punch the upper spring clip 6 and the lower spring clip 4. The function of the knob 10 is to prevent the gas inside the airbag 5 from escaping. When the interior of the airbag 5 is full of air, turn the knob 10 to prompt the threaded column to drive the blocking block to block the inside of the air inlet pipe 7, thereby avoiding the problem of gas backflow inside the airbag 5.

Alignment blocks 12 are fixedly connected to both sides of the bottom of the upper card box 26, and the specifications and sizes of the alignment blocks 12 are adapted to the specifications and sizes of the card slot 16. A support spring 17 is also fixedly connected to the inside of the airbag 5, and the support spring The top of the spring 17 is fixedly connected to the top of the inside of the airbag 5, and the bottom of the support spring 17 is fixedly connected to the bottom of the inside of the airbag 5. By setting the bottom of both sides of the upper spring clamp 6 to be L-shaped, the connection and fixation of the upper clamp 26 and the upper spring clamp 6 are facilitated. At the same time, the alignment groove 13 and the alignment block 12 are set, the upper clamp 26 can be stably fixed on the top of the lower clamp 3, thereby facilitating the subsequent filling of the airbag 5. At the same time, by setting a support spring 17 inside the upper spring clamp 6, it can support the upper spring clamp 6 while enabling the upper spring clamp 6 to move downward, thereby facilitating the connection between the upper clamp 26 and the lower clamp 3.

The outside of the top of the conical cylinder 24 is fixedly connected with a sponge pad 25, and the outside of the top of the straight cylinder 21 is fixedly connected with a fixing ring, and the position of the fixing ring corresponds to the position of the sponge pad 25.

[0032] The waterproof component is provided, which can not only stabilize and fix the bottom box 1 and the inspection cover 2 for connection, but also prevent external water from entering the interior of the bottom box 1 from the screws. When fixing, the bolt 19 is threaded through the interior of the inspection cover 2 and connected to the interior of the top of the conical cylinder 24. At this time, the bottom of the bolt 19 will be fixed to the top of the inside of the conical cylinder 24. After that, when water flows into the top of the bolt 19, the water will flow downward along the bolt 19. When the water flows to the hole inside the bolt 19, the water will flow from the hole at the bottom of the bolt 19 to the inside of the conical cylinder 24.
