Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0021] like Figures 1 to 8 As shown, this utility model discloses a multi-cable through-wall sealing device. The technical solution includes a disc-shaped auxiliary seat 1, with a cable passage hole 104 in the middle of the disc-shaped auxiliary seat 1, a threaded hole 102 and a countersunk hole 103 on the disc-shaped auxiliary seat 1, a conical sealing surface 101 on the cable passage hole 104, an annular boss 105 at the bottom of the disc-shaped auxiliary seat 1, and a sealing plug 2 on the disc-shaped auxiliary seat 1. The sealing plug 2 is a corrosion-resistant sealing element, which can be either a rubber element or a silicone element. The sealing plug 2 has four cable placement holes 202, which are used to wrap the cables individually to prevent gaps between the cables from affecting the sealing effect. There is a cable passage gap 203 between the cable placement hole 202 and the edge of the sealing plug 2 to facilitate the rapid insertion of the cables. The sealing plug 2 is quickly inserted, and a fixing hole 204 is opened on it. The fixing hole 204 is concentric with the threaded hole 102. The bottom of the sealing plug 2 is provided with a conical sealing surface 201. The conical sealing surface 201 is interference-fitted with the threaded sealing surface 202. The top of the sealing plug 2 is provided with an upper pressure plate 3. The upper pressure plate 3 and the sealing plug 2 are fixed together by fastening screws 6, fixing hole 204 and threaded hole 102. The upper pressure plate 3 is used to squeeze the sealing plug 2, so that when the sealing plug 2 deforms, the gap between the wire and the thread seam 203 is tighter, achieving better sealing performance. The countersunk hole 103 contains a countersunk screw 5. The annular boss 105 below the disc-shaped auxiliary seat 1 has a sealing gasket 4. The sealing gasket 4 ensures a good sealing effect between the disc-shaped auxiliary seat 1 and the wall.

[0022] The working principle of this utility model is as follows: When cables need to pass through walls, holes are first drilled in the wall and the annular protrusion 105 is placed inside the holes. If the wall is made of a weldable material, the disc-shaped auxiliary seat 1 can be directly welded to the wall to achieve sealing and fixation. If the wall is not made of a weldable material, a sealing gasket 4 is placed between the disc-shaped auxiliary seat 1 and the wall, and the disc-shaped auxiliary seat 1 is threaded to the wall using countersunk screws 5 and countersunk holes 103 to achieve sealing between the disc-shaped auxiliary seat 1 and the wall. Afterward, the cable is passed through the thread seam 203. Insert the cable into the cable hole 202, place the sealing plug 2 into the cable passage hole 104, align the fixing hole 204 with the threaded hole 102, then place the upper pressure plate 3 above the sealing plug 2, and connect the fastening screw 6 through the upper pressure plate 3 and the fixing hole 204 to the threaded hole 102. At this time, the sealing plug 2 will deform by compression, and the gap between the cable, the cable passage 203, and the gap between the first conical sealing surface 101 and the second conical sealing surface 201 will be sealed by compression, thereby achieving the sealing effect of the cable passing through the wall.

[0023] The mechanical connection involved in this utility model is a common method used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. It is common knowledge.

[0024] Components not described in detail in this article are existing technologies.
