[0002] Cable protection pipes are protective conduits with a certain mechanical strength, laid on the outer layer of cables to prevent damage. They are mainly installed at intersections where communication cables and power lines cross to protect cables, switches, circuit boards, and even the entire device from burning out. They also provide some isolation against magnetic field interference from power lines.
[0003] Chinese Patent CN220209874U discloses a high-strength power cable protection tube, comprising an upper protection tube and a lower protection tube disposed on the lower surface of the upper protection tube. Two fixing strips are symmetrically and horizontally arranged on the outer wall of the upper protection tube, and several fixing screws are equidistantly arranged on the upper surface of the two fixing strips. This invention uses a tool to tighten the fixing screws, connecting the front end of the fixing screw to the threaded hole on the mounting strip, thereby fixing the upper and lower protection tubes. This effectively reduces the possibility of the protection tube falling off. Furthermore, this protection tube eliminates the need for cable sleeve installation, and its assembly-fixed connection facilitates subsequent disassembly and maintenance.
[0004] However, the above-mentioned publicly available solutions have the following shortcomings: fixing the upper and lower protective tubes with screws requires workers to install multiple screws one by one in actual installation scenarios, which significantly increases installation time and labor costs, resulting in low operational efficiency. Furthermore, no interface sealing solution is provided at the connection ports on the left and right ends of the upper and lower protective tubes, which causes inconvenience to the connection of the protective tubes.

[0018] Example 1
[0019] like Figures 1 to 3 As shown, this utility model proposes a high-strength power cable protection pipe, including a pipe body 1, a first connecting seat 2, a second connecting seat, and a limiting seat 3. The inner wall of the pipe body 1 is provided with a reinforcing core, which is made of high-strength glass fiber reinforced plastic. Its tensile strength and bending strength are superior to ordinary plastics and metals, and its weight is lighter, which can improve the impact resistance and bending resistance of the protection pipe. The first connecting seat 2 is installed at one end of the pipe body 1 and is integrally formed with the pipe body 1. The second connecting seat is installed at the other end of the pipe body 1, corresponding to the first connecting seat 2, and is integrally formed with the pipe body 1. The limiting seat 3 is movably sleeved on the outer circumferential surface of the pipe body 1. The limiting seat 3 has a relief opening 301 corresponding to the pipe body 1, which contacts the outer circumferential surface of the pipe body 1. The inner wall of the limiting seat 3 is provided with a first threaded part, and the second connecting seat is provided with a second threaded part, with the first threaded part corresponding to the second threaded part.
[0020] Furthermore, a slot 201 is provided on the first connecting seat 2 at the end away from the tube body 1, and a second sealing gasket 6 is provided in the slot 201;
[0021] Furthermore, the second connecting seat consists of an abutment seat 4 installed at the end of the tube body 1 and a socket 401 installed on the abutment seat 4. The socket 401 is slidably inserted into the slot 201 and abuts against the second sealing gasket 6. The outer wall of the socket 401 is movably fitted with a first sealing gasket 5, which is pressed between the abutment seat 4 and the first connecting seat 2. The second threaded part is provided on the outer wall of the abutment seat 4, and the abutment seat 4 is threadedly connected to the inner wall of the limiting seat 3. Both the first sealing gasket 5 and the second sealing gasket 6 are made of aging-resistant rubber material to improve the sealing performance at the abutment. The outer diameter of the first connecting seat 2 is slightly smaller than the inner diameter of the limiting seat 3 to avoid interfering with the rotation adjustment of the limiting seat 3 and the threaded connection with the abutment seat 4.
[0022] Furthermore, the inner wall of the socket 401 is provided with guide strips 402, and multiple sets of guide strips 402 are provided. The slot 201 is provided with corresponding guide grooves 202. The guide strips 402 and guide grooves 202 are slidably inserted into each other to limit the socket 401 and the first connecting seat 2, so as to prevent relative rotation and improve the stability of the connection.
[0023] Furthermore, an adjustment seat 302 is provided on the outer wall of the limiting seat 3. The adjustment seat 302 has a recessed part. The adjustment seat 302 is integrally formed with the limiting seat 3. Multiple sets of adjustment seats 302 are provided. By inserting any suitable rod-shaped external tool into the recessed part, the limiting seat 3 can be rotated and adjusted along the outer wall of the tube body 1, saving the output of rotational force and facilitating adjustment.
[0024] In this embodiment, when it is necessary to connect two adjacent sets of protective tubes, the second sealing gasket 6 is first inserted into the slot 201, and then the first sealing gasket 5 is fitted onto the outer wall of the socket 401. Next, the socket 401 on the second connecting seat is inserted into the corresponding slot 201, and the guide strip 402 is inserted into the guide groove 202 until the socket 401 presses the second sealing gasket 6 against the slot 201. At the same time, the abutment seat 4 presses the first sealing gasket 5 against the first connecting seat 2. Then, the limiting seat 3 is rotated along the tube body 1, so that the first threaded part on the inner wall of the limiting seat 3 is threadedly connected to the second threaded part on the outer wall of the abutment seat 4. Finally, the limiting seat 3 stably limits the first connecting seat 2 and the abutment seat 4. The sealing performance of the connection is improved by the first sealing gasket 5 and the second sealing gasket 6, preventing external interference from entering the tube body 1 and interfering with the cable. The installation is convenient and quick. In addition, the first connecting seat 2 and the second connecting seat are respectively set at both ends of the tube body 1, which improves the overall integrity of the protective tube.
[0025] Example 2
[0026] like Figure 4 As shown, the high-strength power cable protection pipe proposed in this utility model, compared with Embodiment 1, the pipe body 1 includes an insulating and heat-insulating pipe 101, a reinforcing rib 103, and an outer protective layer 104; the reinforcing inner core is set on the inner wall of the insulating and heat-insulating pipe 101, which is the prior art, consisting of an insulating pipe body and a heat-insulating pipe body connected together, and will not be described in detail; the reinforcing rib 103 is evenly wound around the outer wall of the insulating and heat-insulating pipe 101, and the reinforcing rib 103 is set as a spiral wound steel strip, and the outer wall of the insulating and heat-insulating pipe 101 is also provided with a fireproof layer 102, which is set as a high-temperature resistant fireproof coating; the outer protective layer 104 is set outside the reinforcing rib 103, and the outer protective layer 104 is made of wear-resistant modified polypropylene material and is extruded to cover the reinforcing rib 103 and the insulating and heat-insulating pipe 101, and the outer wall of the outer protective layer 104 is also provided with an anti-corrosion layer 105, which is set as an anti-corrosion coating.
[0027] In this embodiment, by wrapping reinforcing ribs 103 around the outer wall of the insulating heat insulation pipe 101, the resistance to external extrusion and crushing can be enhanced, the service life can be extended, and the protective performance can be improved. The outer protective layer 104 can cover the reinforcing ribs 103 and the insulating heat insulation pipe 101 to achieve a sealing effect, improve the overall performance, and can also play a role in corrosion prevention and wear resistance for the reinforcing ribs 103. The fireproof layer 102 improves the fireproof performance. The anti-corrosion layer 105 improves the corrosion resistance and moisture resistance. The overall strength of the pipe body 1 is high, the fireproof and corrosion resistant effect is better, and the service life is extended. It should be noted that the materials of the first connecting seat 2, the limiting seat 3, and the second connecting seat are the same as those of the pipe body 1.
[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
