Description

Technical Field

[0001] The utility model relates to the technical field of wall-passing wire pipes, in particular to a wall-passing wire pipe closed structure. Background Art

[0002] Wall conduit refers to a special pipe that passes through the walls, floor slabs and other physical parts of a building and is used to run wires, cables and other lines. Its main purpose is to protect internal lines from damage, prevent fire and facilitate later line maintenance.

[0003] When users choose through-wall wire conduits, they usually use through-wall sleeves with sealing properties. Both ends of the sleeves are equipped with sealing gaskets or self-expanding materials. When the sleeves are installed, they are expanded by squeezing or inflation to fit tightly against the wall and the wire conduit, forming a tight sealing layer. Although this method can perform a sealing operation on both ends of the wire conduit, the service life of the sealing gaskets or expansion materials is limited. They may age, harden, lose elasticity and have weakened sealing properties due to long-term influences such as temperature changes, wind, sun or chemical erosion. Therefore, the present invention aims to provide a through-wall wire conduit sealing structure that can seal the port of the wire conduit for a long time. Utility Model Content

[0004] (1) Technical problems solved

[0005] In view of the deficiencies of the prior art, the present invention provides a wall-through wire pipe sealing structure, which can seal the port of the wire pipe for a long time, thereby solving the problem in the prior art that it is difficult to seal the port of the wire pipe for a long time.

[0006] (2) Technical solution

[0007] In order to achieve the above-mentioned purpose, the utility model provides a sealed structure for a through-wall wire pipe, including a tube body and a wire body, and also including a rubber ring, which is arranged in the tube body and fixed to the inner wall of the tube body, and the rubber ring is provided with an opening suitable for the movable insertion of the wire body; a clamping part, which is arranged in the tube body and is movably penetrated by a shaft column, and the shaft column is fixed on the tube body, and the clamping part is provided with a clamping opening, and the end of the clamping part facing away from the shaft column is connected to the rubber ring; and a torsion spring, which is arranged in the clamping opening and is sleeved on the shaft column to elastically abut the clamping part against the center of the rubber ring, thereby squeezing the opening.

[0008] Optionally, a plurality of rubber rings are arranged at intervals in the opening on the rubber ring.

[0009] Optionally, the rubber ring has a hollow structure.

[0010] Optionally, a sealing tube is provided on the tube body, and the sealing tube has a sealing opening, and the sealing opening is suitable for inserting the wire body.

[0011] Optionally, the wire body is provided with a first threaded portion, the first threaded portion is threadedly connected to the sealing port, and the wire body is further provided with a sealing portion, the diameter of the sealing portion is larger than the diameter of the sealing port.

[0012] Optionally, a second threaded portion is provided on the tube body, and the second threaded portion is threadedly connected to the sealing tube.

[0013] (3) Beneficial effects

[0014] Compared with the prior art, the present invention provides a wall-through wire conduit sealing structure with the following features:

[0015] Beneficial effects:

[0016] 1. The present invention provides a clamping portion. When the wire is placed in the tube for a long time, the elasticity of the rubber ring will gradually weaken. At this time, the clamping portion will be continuously elastically abutted by the torsion spring, so that one end of the clamping portion can continuously squeeze the opening of the rubber ring, thereby further reducing the gap between the wire and the rubber ring. This prevents the rubber ring from no longer elastically abutting the wire after losing its elasticity, thereby extending the time the tube can seal the wire.

[0017] 2. This utility model uses rubber rings. When the rubber rings elastically clamp the wire, these rubber rings, through their independent elastic action, fill the gap between the wire and the rubber rings, providing multiple points of contact and sealing. This ensures that the wire remains tightly connected under stress or environmental changes, preventing the intrusion of moisture, dust, etc., thereby effectively improving the overall sealing effect and durability.

[0018] 3. The present invention provides a hollow rubber ring, which enables the rubber ring to better fit the contour of the wire when clamping it. The hollow rubber ring, due to its inherent softness and flexibility, can more tightly wrap the wire. No matter how slight the diameter or surface shape of the wire changes, the hollow rubber ring can adapt and fit closely through the deformation of the hollow rubber ring, thereby achieving more delicate and firm contact.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example: See Figures 1 to 7 According to an embodiment of the utility model, a technical solution is provided: a sealed structure for a through-wall wire pipe, comprising a pipe body 1 and a wire body 2, and also comprising a rubber ring 3, which is arranged in the pipe body 1 and fixed to the inner wall of the pipe body 1, and the rubber ring 3 is provided with an opening 4 suitable for the movable insertion of the wire body 2; a clamping part 5, which is arranged in the pipe body 1 and is movably penetrated by a shaft column 6, the shaft column 6 is fixed on the pipe body 1, and the clamping part 5 is provided with a clamping opening 7, and the end of the clamping part 5 facing away from the shaft column 6 is connected to the rubber ring 3; and a torsion spring 8, which is arranged in the clamping opening 7 and is sleeved on the shaft column 6 to elastically abut the clamping part 5 against the center of the rubber ring 3, thereby squeezing the opening 4.

[0029] With the above-mentioned wall-through wire tube sealing structure, when the user needs to put the wire body 2 into the tube body 1, he first inserts the wire body 2 into the tube body 1. The wire body 2 will pass through the rubber ring 3, and the rubber ring 3 will elastically squeeze the wire body 2 to reduce the gap between the wire body 2 and the rubber ring 3, and prevent moisture outside the tube body 1 from entering the tube body 1. When the wire body 2 is placed in the tube body 1 for a long time, the elasticity of the rubber ring 3 will gradually weaken. At this time, the clamping part 5 will be continuously elastically abutted by the torsion spring 8, so that one end of the clamping part can continuously squeeze the opening 4 on the rubber ring 3, thereby further reducing the gap between the wire body 2 and the rubber ring 3, and preventing the rubber ring 3 from no longer elastically abutting the wire body 2 after losing its elasticity, thereby extending the time for the tube body 1 to seal the wire body 2.

[0030] In this embodiment, a plurality of rubber rings 9 are provided at intervals in the opening 4 on the rubber ring 3. When the rubber ring 3 elastically clamps the wire body 2, these rubber rings 9 fill the gap between the wire body 2 and the rubber ring 3 through their independent elastic action, providing multi-point contact and sealing, ensuring that the wire body 2 remains tightly connected under stress or environmental changes, preventing the intrusion of moisture, dust, etc., thereby effectively improving the overall sealing effect and durability.

[0031] In this embodiment, the rubber ring 9 has a hollow structure. The hollow structure of the rubber ring 9 enables the rubber ring 9 to better fit the contour of the wire body 2 when clamping the wire body 2. The hollow rubber ring 9 can more tightly wrap the wire body 2 due to its inherent softness and flexibility. No matter how slight the diameter or surface shape of the wire body 2 changes, it can adapt to and fit tightly through the deformation of the hollow rubber ring 9, thereby achieving more delicate and firm contact.

[0032] In this embodiment, a sealing tube 10 is provided on the tube body 1, and the sealing tube 10 has a sealing opening 11, which is suitable for inserting the wire body 2; before inserting the wire body 2 into the tube body 1, the user first inserts the wire body 2 into the sealing opening 11 of the sealing tube 10, thereby further improving the sealing of the wire body 2.

[0033] In this embodiment, a first threaded portion 12 is provided on the wire body 2, and the first threaded portion 12 is threadedly connected to the sealing port 11. A sealing portion 13 is also provided on the wire body 2, and the diameter of the sealing portion 13 is larger than the diameter of the sealing port 11; after the user inserts the wire body 2 into the sealing tube 10, the user rotates the wire body 2 to threadably connect the first threaded portion 12 to the sealing port 11. At this time, the sealing portion 13 will cover the sealing port 11, further improving the sealing line of the tube body 1 to the wire body 2.

[0034] In this embodiment, a second threaded portion 14 is provided on the tube body 1, and the second threaded portion 14 is threadedly connected to the sealing tube 10; when the user needs to replace or maintain the sealing tube 10, the user can disengage the sealing tube 10 from the second threaded portion 14 on the tube body 1 by threading the sealing tube 10, so as to remove the sealing tube 10 from the tube body 1, thereby facilitating the user to replace or maintain the sealing tube 10.

[0035] Working principle: When the user needs to put the wire body 2 into the tube body 1, the wire body 2 is first inserted into the tube body 1. The wire body 2 will pass through the rubber ring 3, and the rubber ring 3 will elastically squeeze the wire body 2 to reduce the gap between the wire body 2 and the rubber ring 3 to prevent moisture from the outside of the tube body 1 from entering the tube body 1. When the wire body 2 is placed in the tube body 1 for a long time, the elasticity of the rubber ring 3 will gradually weaken. At this time, the clamping part 5 will be continuously elastically abutted by the torsion spring 8, so that one end of the clamping part can continuously squeeze the opening on the rubber ring 3. The opening 4 further reduces the gap between the wire body 2 and the rubber ring 3 to prevent the rubber ring 3 from no longer elastically contacting the wire body 2 after losing its elasticity, thereby extending the time for the tube body 1 to seal the wire body 2; when the rubber ring 3 elastically clamps the wire body 2, these rubber rings 9 fill the gap between the wire body 2 and the rubber ring 3 through their own independent elastic action, providing multi-point contact and sealing, ensuring that the wire body 2 remains tightly connected under stress or environmental changes, preventing the intrusion of moisture, dust, etc., thereby effectively improving the overall sealing effect and durability The hollow rubber ring 9 can better fit the contour of the wire body 2 when clamping it. The hollow rubber ring 9 can wrap the wire body 2 more tightly due to its inherent softness and flexibility. No matter how slight the diameter or surface shape of the wire body 2 changes, it can adapt to and fit closely through the deformation of the hollow rubber ring 9, achieving more delicate and firm contact. Before inserting the wire body 2 into the tube body 1, the user should first insert the wire body 2 into the sealing port 11 of the sealing tube 10 to further improve the sealing performance. The sealing performance of the wire body 2 is improved. After the user inserts the wire body 2 into the sealing tube 10, the user rotates the wire body 2 to threadably connect the first threaded portion 12 with the sealing port 11. At this time, the sealing portion 13 will cover the sealing port 11, further improving the sealing performance of the tube body 1 on the wire body 2; when the user needs to replace or maintain the sealing tube 10, the user can disengage the sealing tube 10 from the second threaded portion 14 on the tube body 1 by threading it away, so as to remove the sealing tube 10 from the tube body 1, making it easier for the user to replace or maintain the sealing tube 10.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
