Description

Technical Field

[0001] This application relates to the field of cable protection pipe technology, and in particular to a high-pressure-resistant cable protection pipe. Background Technology

[0002] Cable protection pipes, also known as cable conduits, power cable conduits, cement cable conduits, power ducts, and power cable protection pipes, are mainly installed at the intersections of communication cables and power lines to prevent short circuits caused by power line breaks. They protect cables, switches, circuit boards, and even the entire device from being burned out, and also provide some isolation against magnetic field interference from power lines.

[0003] Currently, in the cable protection pipes in use, the protection pipe only provides internal support and protection for the cable. When one end of the cable passes through the head and tail of the protection pipe, it will come into contact with the end face of the head and tail and be squeezed or compressed, causing scratches on the surface of the cable and affecting the service life of the cable. Therefore, a high-pressure resistant cable protection pipe has been designed to solve the above-mentioned problems. Utility Model Content

[0004] To address this problem, this application provides a high-pressure-resistant cable protection pipe.

[0005] The high-pressure-resistant cable protection pipe provided in this application adopts the following technical solution:

[0006] A high-pressure-resistant cable protection pipe includes a protection pipe body, with limiting rings fixedly connected to both ends inside the protection pipe body. A protection ring is snapped into one side of the limiting ring, and the protection ring fits against the end face of the protection pipe body. The connection between the protection ring and the limiting ring is also matched. The outer surface of the protection ring is an arc-shaped surface.

[0007] Preferably, the protective ring is fixedly connected to the side near the limiting ring, the insert ring is inserted into the limiting ring, and several insert rods are also inserted into the inner side of the limiting ring, with one end of each insert rod also inserted into the insert ring.

[0008] Preferably, a fixing ring is fixedly connected to one side of the limiting ring, and a guide ring is fixedly connected to the inner wall of the fixing ring near the limiting ring.

[0009] Preferably, the guide ring is annular, and a plurality of guide balls are interactively arranged within the guide ring.

[0010] Preferably, a connecting ring is fixedly connected to the side of the fixed ring near the guide ring, and the inner wall of the connecting ring is inclined.

[0011] Preferably, the protective tube body consists of an inner layer, a middle layer and an outer layer, wherein the inner layer is an insulating layer made of PVC material.

[0012] Preferably, the intermediate layer is a pressure-resistant layer made of HDPE material, and the outer layer is a wear-resistant and corrosion-resistant layer made of rubber material.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] In this invention, protective ring structures are installed at both ends of the protective tube. After the protective rings are installed on the protective tube, they cover the end face of the protective tube, preventing the cable from being vertically connected to the end wall of the protective tube body when the cable passes through the protective tube body, thus avoiding indentation or damage. Furthermore, guide rings and guide balls are used to limit and fix the cable, ensuring that the cable is stably supported inside the protective tube body, making it convenient to use the protective tube to protect the cable.

[0019] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0020] This application discloses a high-pressure-resistant cable protection pipe. (Refer to...) Figure 1-3 A high-pressure-resistant cable protection pipe includes a protection pipe body 1 with limiting rings 2 fixedly connected to both ends. A protection ring 3 is snapped onto one side of the limiting ring 2. The protection ring 3 fits against the end face of the protection pipe body 1, and the connection between the protection ring 3 and the limiting ring 2 is perfectly aligned. The outer surface of the protection ring 3 is arc-shaped. Figure 2 As shown, the protective ring 3 is fixedly connected to the insertion ring 31 on the side near the limiting ring 2. The insertion ring 31 is inserted into the limiting ring 2. Several insertion rods 4 are also inserted into the inner side of the limiting ring 2. One end of the insertion rod 4 is also inserted into the insertion ring 31. By using the insertion ring 31 to insert into the limiting ring 2, the protective ring 3 can be easily disassembled. If the protective ring 3 is damaged during continuous installation and use in the outside, it can be quickly replaced so as to facilitate the continuous use of the protective tube body 1.

[0021] The cable passes through one end of the protective tube body 1 and will come into contact with the side of the protective ring 3. The arc-shaped design of the protective ring 3 can reduce the pressure on the cable and prevent the cable from being vertically connected to the end wall of the protective tube body 1, resulting in indentations or damage.

[0022] By adopting the above technical solution, a fixed ring 5 is fixedly connected to one side of the limiting ring 2, and a guide ring 7 is fixedly connected to the inner wall of the fixed ring 5 near the limiting ring 2. The guide ring 7 is annular, and a number of guide balls 8 are interactively arranged inside the guide ring 7. The guide balls 8 can rotate inside the guide ring 7. When the cable passes through the guide ring 7, it will be guided and transported by the guide balls 8, so that the cable passes through the guide ring 7, and the guide ring 7 and the guide balls 8 are used to support and protect the cable.

[0023] A connecting ring 6 is fixedly connected to the inner side of the fixing ring 5 near the guide ring 7. The inner wall of the connecting ring 6 is inclined. Figure 2 As shown, it is used to guide the cable into the guide ring 7.

[0024] By adopting the above technical solution, the protective tube 1 is composed of an inner layer 11, a middle layer 12 and an outer layer 13. The inner layer 11 is an insulating layer made of PVC material, which can protect the cable from the influence of the external environment and maintain the insulation of the cable. The middle layer 12 is a pressure-resistant layer made of HDPE material, which provides pressure resistance and protects the cable from external pressure. The outer layer 13 is a wear-resistant and corrosion-resistant layer made of rubber material, which increases wear resistance and corrosion resistance to adapt to harsher environments.

[0025] The implementation principle of a high-pressure-resistant cable protection pipe according to an embodiment of this application is as follows: the insertion ring 31 of the protective ring 3 is inserted into one side of the limiting ring 2, so that the protective ring 3 fits against the side wall of the protective pipe body 1. Then, the insertion rod 4 is inserted into the limiting ring 2 and passes through the side wall of the limiting ring 2 to insert into the insertion ring 31, thereby fixing the protective ring 3. Then, the cable passes through one end of the protective pipe body 1. The cable will contact the side of the protective ring 3. The arc-shaped surface design of the protective ring 3 can reduce the pressure on the cable and prevent the cable from being vertically connected to the end wall of the protective pipe body 1, resulting in indentation or damage. If the cable continues to be transported, it will pass through the guide ring 7 and be continuously transported by the guide ball 8, and the cable will be limited and fixed to ensure that the cable is stably supported in the protective pipe body 1. Then, it is guided by the inclined surface of the connecting ring 6 at the other end of the protective pipe body 1 and re-enters the guide ring 7. After being guided by the guide ball 8, it is exposed from the other side of the protective pipe body 1.
