Description

Technical Field

[0001] This utility model relates to the field of cable protection technology, and in particular to a power cable protection pipe that is easy to install. Background Technology

[0002] Cable protection pipes are mainly laid on the outer layer of cables to prevent cable damage. During the cable laying process, cable protection pipes need to be installed on the outside to protect the cables.

[0003] Currently, during the installation of existing power cable protection pipes, because the pipes are integrally formed, the cable needs to pass through one end of the pipe. This process causes friction between the cable end and the inner wall of the pipe, resulting in time-consuming and labor-intensive installation. It prevents the cable protection pipe from being quickly and efficiently fitted onto the cable. Therefore, to improve the installation efficiency of power cable protection pipes and to promote technological advancement and enhance core technological competitiveness in the industry, this application proposes a new implementation scheme for power cable protection pipes that differs from existing technologies. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an easy-to-install power cable protection pipe to solve the problem that in the laying process of the existing power cable protection pipe, because the power cable protection pipe is integrally formed, the cable needs to pass through the protection pipe from one end, and the cable end rubs against the inner wall of the protection pipe when passing through, which makes the installation of the protection pipe time-consuming and laborious, and cannot quickly and efficiently put the cable protection pipe on the cable.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An easy-to-install power cable protection pipe includes a pipe body with multiple grooves on the inner circumference of the pipe body, a fixing ring inside the pipe body, and multiple connecting ears fixedly connected to the outer circumference of the fixing ring. A roller is rotatably connected between two connecting ears via a rotating shaft, and the roller rolls in the grooves. The circumference of the fixing ring is provided with multiple threaded holes, and a clamping bolt is threaded into the threaded holes.

[0006] Furthermore, a connecting pipe is provided between two adjacent pipe bodies.

[0007] Furthermore, both ends of the connecting pipe are provided with slots, and one end of the pipe body is engaged with the slot.

[0008] Furthermore, one end of the clamping bolt is provided with an anti-slip groove.

[0009] Furthermore, a gap is provided between the fixing ring and the tube body.

[0010] Compared with the prior art, the beneficial technical effects of this utility model are as follows: 1. By inserting one end of the cable into one end of the pipe and then pushing the cable to make the roller roll in the groove, the sliding friction is converted into rolling friction, thereby reducing the resistance of the cable passing through the pipe and allowing the cable to smoothly pass into the pipe, saving time and effort.

[0011] 2. By tightening the clamping bolt, one end of the clamping bolt comes into contact with the outer wall of the cable, thereby clamping the cable passing through the fixing ring to facilitate cable insertion. Loosening the clamping bolt leaves the fixing ring inside the cable protection tube, which can also be used to support the cable. Attached Figure Description

[0015] Reference Figures 1-3An easy-to-install power cable protection pipe includes a pipe body 1, a plurality of sliding grooves 2 are provided on the inner circumference of the pipe body 1, a fixing ring 3 is provided inside the pipe body 1, a plurality of connecting ears 4 are welded on the outer circumference of the fixing ring 3, and a roller 5 is rotatably connected between two connecting ears 4 through a rotating shaft, and the roller 5 rolls in the sliding groove 2. Insert the cable into the fixing ring 3, then pass one end of the cable through one end of the tube 1, and make the roller 5 located in the groove 2. Then push the cable to make the roller 5 roll in the groove 2, thereby converting the sliding friction into rolling friction, thereby reducing the resistance of the cable passing through the tube 1, and thus making the cable smoothly pass into the tube 1. The circumference of the fixing ring 3 is provided with multiple threaded holes 6, and the threaded holes 6 are connected to the clamping bolts 7. Tightening the clamping bolts 7 will cause one end of the clamping bolts 7 to contact the outer wall of the cable, thereby clamping the cable passing through the fixing ring 3. The tightening torque is 1-5 N·m to ensure that it is tightened in, so as to facilitate the cable insertion.

[0016] A connecting pipe 8 is provided between two adjacent pipe bodies 1. Both ends of the connecting pipe 8 are provided with slots 9. One end of the pipe body 1 is inserted into the slot 9. One end of the pipe body 1 is inserted into the slot 9 at one end of the connecting pipe 8 and then fixed with glue, which facilitates the connection between two adjacent pipe bodies 1 and thus facilitates the connection and fixing of the cable protection pipe.

[0017] One end of the clamping bolt 7 is provided with an anti-slip groove, which facilitates the operation of the clamping bolt 7, making it convenient and quick.

[0018] A gap is provided between the fixing ring 3 and the tube body 1, which not only provides space for heat dissipation of the cable, but also allows for easy manual tightening of the clamping bolt 7.

[0019] The working principle of this embodiment is as follows: In use, firstly, the cable is passed through the fixing ring 3, and the clamping bolt 7 is tightened, so that one end of the clamping bolt 7 contacts the outer wall of the cable, thereby clamping and fixing the cable passing through the fixing ring 3. Then, the roller 5 is positioned in the sliding groove 2, and the cable is pushed to make the roller 5 roll in the sliding groove 2, thereby converting sliding friction into rolling friction, thereby reducing the resistance of the cable passing through the tube 1, so that the cable can be smoothly passed into the tube 1, which facilitates the insertion of the cable and facilitates the installation of the cable protection tube.

[0020] When the laying distance of the power cable exceeds the length of a single section of protective pipe, one end of the pipe body 1 is connected to the slot 9 at one end of the connecting pipe 8 to facilitate the connection between two adjacent pipe bodies 1. Then, special adhesive is used to fix the two pipe bodies 1 together. Then, the clamping bolt 7 is loosened without clamping the cable, and the fixing ring 3 is left in the cable protection pipe, which can also be used to support the cable.

[0021] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0022] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
