[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a through-wall sealing structure.

[0004] This utility model is achieved through the following technical solution:

[0005] A through-wall sealing structure includes a sealing pipe and a first equipment housing. A sealing body is provided on one side of the sealing pipe, and a second equipment housing is provided on one side of the sealing pipe. An M5 bolt is provided on one side of the second equipment housing. A first flange is provided at the bottom of the sealing body, and an O-ring is provided on one side of the first flange. An equipment body is provided on one side of the first equipment housing, and an M8 socket head cap screw is provided on one side of the sealing body. A stainless steel sealing block is provided on one side of the first equipment housing, and a second conical sealing ring is provided on one side of the stainless steel sealing block.

[0006] As can be seen, in the above technical solution, when adding a cable, the user can squeeze the first conical sealing ring to one side by rotating the tightening bolt to achieve the effect of fastening the device. At the same time, it can also improve the sealing performance during use. When sixteen cables need to be passed through, the cables can be placed in the second conical sealing ring and the stainless steel sealing block. In this way, when using the cable, after passing it through, rotating the tightening bolt can achieve a good sealing treatment for the cable.

[0007] Optionally, in one possible implementation, a clamping bolt is provided on one side of the sealing tube, and the sealing tube passes through the clamping bolt, the surface of the clamping bolt being threaded.

[0008] As can be seen, in the above technical solution, the tightening effect can be enhanced by the added clamping bolts when using the device, and it is also more convenient to disassemble. Simply rotate the clamping bolts in the opposite direction to open it.

[0009] Optionally, in one possible implementation, a first conical sealing ring is provided on one side of the sealing pipe, and the first conical sealing ring is fitted to the sealing pipe.

[0010] As can be seen, in the above technical solution, the device can be moved easily by the added first conical sealing ring, which makes it more convenient to use.

[0011] Optionally, in one possible implementation, the top of the device body is provided with sixteen cables, which run through both sides of the device body and are arranged in a matrix.

[0012] As can be seen, in the above technical solution, the cable can be installed through the main body of the device when using the device, which makes disassembly and installation more convenient.

[0013] Optionally, in one possible implementation, a second flange is provided on one side of the first device housing, and the second flange is fitted to one side of the device housing.

[0014] As can be seen, with the addition of a second flange, the above technical solution enables the equipment to be used in harsh environments, extending its service life and reducing operating costs.

[0015] Optionally, in one possible implementation, the second flange has an opening inside, and an O-ring is provided inside the opening of the second flange.

[0016] As can be seen, in the above technical solution, the second flange has an opening inside, and some material can be removed through the opening, which reduces the weight of the second flange, making it easier to install and handle. After adding an O-ring, it can provide additional sealing protection, effectively preventing a large amount of gas leakage. At the same time, even if there are minor unevenness or defects on the surface of the second flange, the O-ring can still provide a good sealing effect, increasing the reliability of the seal.

[0017] Optionally, in one possible implementation, sixteen fastening bolts are provided on one side of the main body of the device, and the fastening bolts are arranged in a matrix, with each fastening bolt having a different diameter.

[0018] As can be seen, the above technical solution can be effectively tightened using bolts, which will make it more secure during long-term use.

[0019] The beneficial effects of this utility model are:

[0020] When adding multiple cables, users can place the cables into the second conical sealing ring and the stainless steel sealing block. After inserting the cables, the tightening bolts can be rotated to clamp the cables securely, making the process more convenient. When adding a single cable, rotating the tightening bolts a certain number of turns can compress the first conical sealing ring to one side, thus securing the device and improving its sealing performance.

[0021] The design incorporates O-rings and O-ring seals on both sides of the first and second flanges. This design ensures that the O-rings provide excellent elasticity and sealing performance during use, offering additional sealing protection and effectively preventing large-scale gas leakage. Simultaneously, the O-rings can compensate for minor deformations and vibrations between the second flange and the connecting components, maintaining reliable sealing. Even with minor unevenness or defects on the surface of the second flange, the O-rings still provide a good sealing effect, increasing the reliability of the seal. Attached Figure Description

One side of the first equipment housing 16 is provided with an equipment body 14. One side of the sealing body 4 is provided with an M8 ring head hex bolt 11. One side of the first equipment housing 16 is provided with a second flange 13, and the second flange 13 fits with the first equipment housing 16 and the second equipment housing 17. The second flange 13 has an opening inside, and the opening of the second flange 13 has an O-ring 6. One side of the first equipment housing 16 is provided with a stainless steel sealing block 9, and one side of the stainless steel sealing block 9 is provided with a second conical sealing ring 8.

[0031] Usage process:

[0032] When adding a cable 10, the user can squeeze the first conical sealing ring 3 to one side by rotating the clamping bolt 2 a certain number of turns. This can achieve the effect of tightening the device and improve the sealing performance during use. When sixteen cables 10 need to be passed through, the cables can be placed in the second conical sealing ring 8 and the stainless steel sealing block 9. After the cables 10 are passed through, the clamping bolt 15 can be rotated to clamp the cables 10 well. A single sealing pipe 1 can be used to seal the perforated air duct between rooms. When multiple cables 10 are used, the device can be used to seal the cable perforation between compartments. The clamping bolt 2 is tightened to deform the first conical sealing ring 3 and the second conical sealing ring 8 along the conical hole of the sealing body 4, thus achieving the sealing performance of the sealing pipe 1.

[0033] Example 2: As shown in the figure, it includes a sealing pipe 1 and a first equipment housing 16. A sealing body 4 is provided on one side of the sealing pipe 1, and a clamping bolt 2 is provided on the same side, with the sealing pipe 1 passing through the clamping bolt 2. The surface of the clamping bolt 2 is threaded. A first conical sealing ring 3 is provided on one side of the sealing pipe 1, and the first conical sealing ring 3 fits against the sealing pipe 1. A second equipment housing 17 is provided on one side of the sealing pipe 1, and an M5 bolt 5 is provided on one side of the second equipment housing 17. Sixteen cables 10 are provided on the top of the sealing body 4, and the cables 10 pass through both sides of the sealing body 4. The cables 10 are arranged in a matrix. Sixteen fastening bolts 15 are provided on one side of the sealing body 4. The fastening bolts 15 are arranged in a matrix, each fastening bolt 15 having a different diameter. The bottom of the sealing body 4 is provided with a first flange 7, and one side of the second flange 13 is provided with an O-ring 12.

The second flange 13 has an opening inside, and some material can be removed through the opening to reduce the weight of the second flange 13, making it easier to install and transport. After adding the O-ring 12, it can provide additional sealing protection, effectively preventing a large amount of gas leakage. At the same time, even if there are minor unevenness or defects on the surface of the second flange 13, the O-ring 12 can still provide a good sealing effect, increasing the reliability of the seal.

[0035] Usage process:

[0036] The user tightens the M5 bolt 5, causing the O-ring 12 to deform and complete the seal between the sealing body 4 and the first flange 7. The stainless steel sealing block 9 presses down, causing the second conical sealing ring 8 to deform along the conical hole of the sealing body 4, thus achieving a seal between the sealing body 4 and the cable 10. Tightening the M8 bolt 5 causes the O-ring 12 to deform and complete the seal between the sealing body 4 and the first flange 7.

[0037] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
