Description

Technical Field

[0001] The utility model relates to the technical field of cable protection pipes, in particular to a cable protection pipe facilitating cable laying. Background Art

[0002] A cable protection pipe refers to a protection pipe with a certain mechanical strength that is sleeved on the outer layer of a cable to prevent the cable from being damaged. The cable protection pipe is mainly installed in the section where the communication cable crosses the power line to prevent the power line from breaking and causing a short - circuit accident, which may cause the communication cable and the steel wire rope to be electrified, so as to protect the cable, the switch, the circuit board, and even the whole machine from being burned out, and also play a certain role in isolating the magnetic field interference of the power line.

[0003] During the construction process, it is necessary to first lay the cable protection pipe, and then thread the cable inside the cable protection pipe. In this process, the surface of the cable needs to contact and rub against the inner wall of the cable protection pipe. Since most of the outer protective layers of the cable are made of rubber material and the length of the laid cable is relatively long, it is very difficult to pull the cable laid inside due to the strong friction force. Therefore, the cable protection pipe is required to reduce the internal friction to facilitate the cable laying work. Content of the Utility Model

[0004] The utility model aims at the defects in the prior art and provides a cable protection pipe facilitating cable laying.

[0005] The utility model is realized by the following technical solutions:

[0006] A cable protection pipe facilitating cable laying includes a cable protection pipe and an auxiliary cable arranging mechanism arranged inside both ends of the cable protection pipe. The auxiliary cable arranging mechanism includes a fixed seat, a connecting seat, an extension rod, an internal support seat, a roller and a limiting mechanism. The fixed seat is clamped inside both ends of the cable protection pipe. The connecting seat is arranged at the bottom of both ends of the cable protection pipe. The extension rod is fixedly arranged inside the fixed seat. The internal support seat is fixedly arranged at one end of the extension rod. The roller is movably arranged on the tops of the fixed seat and the internal support seat. The limiting mechanism is clamped on the top of one side of the fixed seat. The limiting mechanism includes a pressing block and double - sided tape. The pressing block is clamped on the top of one side of the internal support seat. The double - sided tape is pasted on the bottom of the pressing block.

[0007] In a preferred embodiment of the utility model, the position of the connecting seat corresponds to the position of the fixed seat. The bottoms of the fixed seat and the internal support seat are attached to the inner wall of the cable protection pipe, and the top of the connecting seat is attached to the outer wall of the cable protection pipe;

[0008] The corresponding positions of the connecting seat and the fixed seat facilitate the fixation of the two by screws. The bottoms of the fixed seat and the internal support seat being attached to the bottom of the cable protection pipe avoid gaps at the bottom, which helps the cable to pass through.

[0009] In a preferred embodiment of the present utility model, both sides of the fixed seat and the internal support seat are inclined;

[0010] The inclined surfaces on both sides of the fixed seat and the internal support seat facilitate the guiding of the cable when passing through, thus facilitating the cable laying work.

[0011] In a preferred embodiment of the present utility model, the upper surface of the pressing block and the side surface of the internal support seat are in the same plane, the bottom of the pressing block has the same curvature as the inner wall of the cable protection pipe, and a clamping groove for cooperating with the pressing block is vertically opened on one side of the internal support seat;

[0012] After tearing off the outer film of the double-sided adhesive on the bottom of the pressing block, install the internal support seat with the pressing block clamped, and press down the pressing block so that the double-sided adhesive on its bottom adheres to the inner wall of the cable protection pipe to achieve a fixing effect, thereby preventing the internal support seat from shaking during cable laying.

[0013] In a preferred embodiment of the present utility model, installation grooves are opened at the tops of the fixed seat and the internal support seat, and the top of the roller is 3 mm - 10 mm higher than the bottom of the installation groove at the top of the fixed seat and the internal support seat.

[0014] The beneficial effects of the present utility model are:

[0015] The cable protection pipe facilitating cable laying is provided with an auxiliary wire arranging mechanism at both ends and inside the cable protection pipe. The fixed auxiliary wire arranging mechanism effectively guides the cable during the cable laying process and raises a part of the cable, reducing the contact area between the bottom of the cable and the inner wall of the protection pipe. The roller not only plays a role in raising the cable but also reduces the friction between the cable and the inner wall of the protection pipe when dragging the cable, thus facilitating the cable laying work.

[0019] The following elaborates on the preferred embodiments of the present utility model in conjunction with the accompanying drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making the scope of protection of the present utility model more clearly defined. The directional terms mentioned in the present utility model, such as "upper", "lower", "front", "rear", "left", "right", "top", "bottom", etc., are only references to the directions of the attached drawings. Therefore, the directional terms used are for explaining and understanding the present utility model, rather than for limiting the present utility model.

[0020] As Figures 1-3 shown, a cable protection pipe facilitating cable laying includes a cable protection pipe 1 and an auxiliary wire arranging mechanism 2 disposed inside both ends of the cable protection pipe 1. The auxiliary wire arranging mechanism 2 includes a fixed seat 21, a connecting seat 22, an extension rod 23, an internal support seat 24, a roller 25, and a limiting mechanism 26. The fixed seat 21 is clamped inside both ends of the cable protection pipe 1. The connecting seat 22 is disposed at the bottom of both ends of the cable protection pipe 1. The extension rod 23 is fixedly disposed inside the fixed seat 21. The internal support seat 24 is fixedly disposed at one end of the extension rod 23. The roller 25 is movably disposed on the tops of the fixed seat 21 and the internal support seat 24. The limiting mechanism 26 is clamped on the top of one side of the fixed seat 21. The limiting mechanism 26 includes a pressing block 261 and a double-sided adhesive 262. The pressing block 261 is clamped on the top of one side of the internal support seat 24. The double-sided adhesive 262 is pasted on the bottom of the pressing block 261.

[0021] Specifically, the position of the connecting seat 22 corresponds to the position of the fixed seat 21. The bottoms of the fixed seat 21 and the internal support seat 24 are in contact with the inner wall of the cable protection pipe 1. The top of the connecting seat 22 is in contact with the outer wall of the cable protection pipe 1. The two sides of the fixed seat 21 and the internal support seat 24 are inclined. The upper surface of the pressing block 261 and the side surface of the internal support seat 24 are in the same plane. The bottom of the pressing block 261 has the same radian as the inner wall of the cable protection pipe 1. A clamping groove cooperating with the pressing block 261 is vertically opened on one side of the internal support seat 24. Installation grooves are opened on the tops of the fixed seat 21 and the internal support seat 24. The top of the roller 25 is 3 mm - 10 mm higher than the bottom of the installation groove on the tops of the fixed seat 21 and the internal support seat 24.

[0022] In this embodiment, first, the auxiliary wire arranging mechanism 2 is installed inside both ends of the cable protection pipe 1. In the limiting mechanism 26, after tearing off the bottom protective film of the double-sided adhesive 262 at the bottom of the pressing block 261, the pressing block 261 is clamped into the clamping hole on one side of the internal support seat 24, and it is ensured that the pressing block 261 does not fall to the bottom of the clamping hole. Subsequently, the internal support seat 24 is inserted into the cable protection pipe 1, and the fixed seat 21 and the connecting seat 22 are fixed at a suitable position. The bottom of the fixed seat 21 is in contact with the inner wall of the cable protection pipe 1, and the top of the connecting seat 22 is in contact with the outer wall of the cable protection pipe 1, and the two are fixed by screws to clamp the cable protection pipe 1 to complete the fixing function.

[0023] Furthermore, the inner support base 24 extends into the cable protection pipe 1 under the action of the extension rod 23. At this time, the lower pressing block 261 is pressed down, so that the double-sided tape 262 at its bottom adheres to the inner wall of the cable protection pipe 1, thereby achieving the effect of fixing the inner support base 24. During the cable laying process, the cable passes through the cable protection pipe 1. The end of the cable is guided by the side slopes of the fixed base 21 and the inner support base 24 to reduce unnecessary blockages, and the bottom of the cable is supported by the rollers 25 to reduce the friction with the inner wall of the cable protection pipe 1. The rollers 25 also effectively assist in the cable laying, thus facilitating the dragging of the cable inside the cable protection pipe 1.
