Description

Technical Field

[0001] This utility model relates to the field of protective tube technology, specifically a low-temperature impact-resistant power cable protective tube. Background Technology

[0002] Power cable protection pipes are designed to prevent damage to cables installed inside them. They possess a certain degree of mechanical strength and are mostly made of metal, such as galvanized steel pipes and cast iron pipes, but other materials such as clay pipes and concrete pipes are also used. For example, the prior art, represented by the prior art document "A Low-Temperature Impact Resistant Power Cable Protection Pipe" (application number 202321836141.8), features a buffer protective sleeve inside the external support sleeve. The protection pipe splicing assembly includes a fastening waterproof tape wrapped around the surface of the external support sleeve, and a connecting shaft is installed on one side of the external support sleeve. This invention features an external support sleeve that can be rotated open via a connecting shaft and then secured to the outside of the internal cable body. This allows the entire protective tube to be fitted over the surface of the internal cable body, providing protection and support. The external support sleeve is also secured with waterproof tape to prevent it from coming undone. Furthermore, the positioning rod and positioning holes allow two sets of protective tubes to be joined together to completely enclose the internal cable body, effectively solving the problems of existing technologies. However, its structure still requires improvement, as detailed below:

[0003] In this solution, the installation of the protective tube plug-in structure requires precise installation of the positioning rod and matching hole, a meticulous and tedious process. It necessitates professional operation to ensure accuracy at every step, thereby guaranteeing the stability and safety of the protective tube plug-in structure. Therefore, a low-temperature impact-resistant power cable protective tube is needed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide a low-temperature impact-resistant power cable protection pipe to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A low-temperature impact-resistant power cable protection pipe includes an outer pipe, a gasket on the inner wall of the outer pipe, an mounting block on one end of the gasket, an inner pipe on the inner wall of the mounting block, a plug-in pipe on one end of the inner pipe, and a fixing pipe on one end of the outer pipe. The plug-in pipe and the fixing pipe are connected by a plug-in connection, and a sealing gasket is provided between the plug-in pipe and the fixing pipe and on the inner wall of the fixing pipe.

[0007] As a preferred embodiment of this utility model, the gaskets are provided in multiple sets and are respectively located on the inner wall of the outer tube.

[0008] As a preferred embodiment of this utility model, the gasket has a wave structure and an annular structure, and both the outer tube and the inner tube are made of thermal insulation material.

[0009] As a preferred embodiment of this utility model, the mounting blocks are provided in multiple sets and are respectively located on the outer wall of the inner tube.

[0010] As a preferred embodiment of this utility model, the mounting block has a ring structure, and the inner tube is located inside the outer tube.

[0011] As a preferred embodiment of this utility model, the insertion tube and the fixing tube are respectively located on the opposite outer walls of the outer tube.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, a plug-in tube is used in the low-temperature impact-resistant power cable protection pipe. The cable passes through the inner tube, and the inner tube of the device is sequentially passed through the outer wall of the cable. The plug-in tube is then inserted into the inner wall of the fixing pipe for fixation. When the plug-in tube is inserted into the fixing pipe, the plug-in tube squeezes the sealing gasket because the inner cavity of the fixing pipe is equipped with a sealing gasket, thereby fixing the plug-in tube to the inner wall of the fixing pipe. The installation of the device is simpler, which helps to solve the problem that the installation of the plug-in structure of the protection pipe requires precise installation of the positioning rod and matching hole, which is a meticulous and tedious process.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] For examples, please refer to Figure 1-3This utility model provides a technical solution:

[0020] A low-temperature impact-resistant power cable protection pipe includes an outer pipe 1, a gasket 2 is provided on the inner wall of the outer pipe 1, an installation block 3 is installed at one end of the gasket 2, an inner pipe 4 is installed on the inner wall of the installation block 3, a plug-in pipe 5 is installed at one end of the inner pipe 4, and a fixing pipe 6 is installed at one end of the outer pipe 1. The plug-in pipe 5 and the fixing pipe 6 are connected by a plug-in connection, and a sealing gasket 7 is provided between the plug-in pipe 5 and the fixing pipe 6 and on the inner wall of the fixing pipe 6.

[0021] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 3 Multiple sets of gaskets 2 are provided and are located on the inner wall of the outer tube 1 respectively. Gaskets 2 have a corrugated structure and are annular. The outer tube 1 and the inner tube 4 are both made of thermal insulation material. Multiple sets of mounting blocks 3 are provided and are located on the outer wall of the inner tube 4 respectively. Mounting blocks 3 are annular. The inner tube 4 is located in the inner cavity of the outer tube 1. Insertion tube 5 and fixing tube 6 are located on the opposite outer walls of the outer tube 1 respectively.

[0022] Furthermore, the inner cavities of the outer tube 1 and the inner tube 4 are provided with gaskets 2. When the outer tube 1 is impacted, the impact force will squeeze the gasket 2. When the gasket 2 is impacted, it will deform and displace. At the same time, when the impact force disappears, the gasket 2 will restore its shape, thereby allowing the outer tube 1 to return to its original position.

[0023] The working process of this utility model is as follows: When using the low-temperature impact-resistant power cable protection pipe designed in this scheme, a plug-in tube 5 is installed at one end of the inner tube 4, and a fixed tube 6 is installed at one end of the outer tube 1. The plug-in tube 5 and the fixed tube 6 are connected by a plug-in connection. With the sealing gasket 7 set between the plug-in tube 5 and the fixed tube 6 and located on the inner wall of the fixed tube 6, when it is necessary to extend the length of the protection pipe, simply pass the cable through the inner tube 4, pass the inner tube 4 of the device through the outer wall of the cable in sequence, and insert the plug-in tube 5 into the inner wall of the fixed tube 6 for fixation. At the same time, when the plug-in tube 5 is inserted into the fixed tube 6, because the inner cavity of the fixed tube 6 is provided with the sealing gasket 7, the plug-in tube 5 squeezes the sealing gasket 7, thereby fixing the plug-in tube 5 to the inner wall of the fixed tube 6 for fixation. The installation of the device is simpler, which helps to solve the problem that the installation of the plug-in structure of the protection pipe requires precise installation of the positioning rod and matching hole, which is a meticulous and tedious process.

[0024] 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
