Technical Field

[0001] The utility model relates to the technical field of power pipes, in particular to a PVC power pipe that can reduce the friction between a cable and a pipe. Background Art

[0002] The PVC power pipe refers to various specifications of rigid polyvinyl chloride pipes mainly made of PVC resin and added with various stabilizers. Because it has strong corrosion resistance, is not affected by corrosive soil, has a smooth inner wall, has less frictional resistance than other materials, is convenient for construction, and has a wide range of uses. In the existing technology, when installing a cable in the PVC power pipe, the outer surface of the cable will contact the inner surface of the entire power pipe, increasing the contact area between the cable and the power pipe, increasing the friction between the cable and the power pipe. At the same time, the cables in the power pipe are wound around each other, increasing the friction between the cables, thus increasing the force required to pull the cable subsequently, reducing the efficiency of cable installation, and making it inconvenient to install the cable. Therefore, a PVC power pipe that can reduce the friction between a cable and a pipe and improve the cable installation efficiency is proposed. Summary of the Invention

[0022] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative position relationship, movement status, etc. between the various components in a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.

[0023] See attachedFigures 1-4 As shown in the figure, a PVC power pipe that can reduce the friction between the cable and the pipe includes a power pipe body 1. The feature is that a connecting spacer 2 that facilitates the connection between the power pipe bodies 1 and can reduce the friction between the power pipe body 1 and the cable, and a locking sleeve 3 for fixing the connecting spacer 2 are installed on the power pipe body 1. A pre-limiting boss 301 for pre-fixing between the connecting spacer 2 and the power pipe body 1 is provided on the locking sleeve 3. A number of partition mounting holes 201 for separately mounting cables are also provided on the connecting spacer 2. The diameter of the partition mounting hole 201 is larger than the diameter of the cable. By using the connecting spacer 2 to connect the power pipe bodies 1, when the cable is pulled, the cable directly contacts the connecting spacer 2, reducing the contact area between the cable and the power pipe body 1, reducing the friction between the cable and the power pipe body 1. At the same time, the cables are separately installed through the partition mounting holes 201, reducing the friction between the cables, thereby further improving the convenience and efficiency of cable installation. By using the locking sleeve 3 to lock and fix the connecting spacer 2 to the power pipe body 1, the connection between the power pipe bodies 1 is facilitated.

[0024] Refer to the appendix Figures 2-4 As shown in the figure, locking installation grooves 202 for facilitating the installation of the locking sleeve 3 are provided on both the connecting spacer 2 and the power pipe body 1. A locking member 302 for locking the locking sleeve 3 is installed on the locking sleeve 3. A pre-positioning groove 203 adapted to the pre-limiting boss 301 on the locking sleeve 3 is provided in the installation groove 204. The locking member 302 can be a locking bolt or a locking screw. By installing the pre-limiting boss 301 on the locking sleeve 3 into the pre-positioning groove 203 in the installation groove 204 on the connecting spacer 2 and the power pipe body 1, the connection between the connecting spacer 2 and the power pipe body 1 is pre-fixed, and the locking sleeve 3 is locked by using the locking member 302, thereby facilitating the fixation between the connecting spacer 2 and the power pipe body 1.

[0025] Refer to the appendix Figures 2-4 As shown in the figure, an installation groove 204 for installing on the power pipe body 1 is provided on the connecting spacer 2. An installation boss 101 adapted to the installation groove 204 is provided on the power pipe body 1. A sealing ring 205 for sealing between the connecting spacer 2 and the power pipe body 1 is installed in the installation groove 204. By installing the installation groove 204 on the connecting spacer 2 into the installation boss 101 on the power pipe body 1, the installation of the connecting spacer 2 is facilitated, and at the same time, the sealing between the connecting spacer 2 and the power pipe body 1 is improved by using the sealing ring 205.

[0026] Refer to the appendix Figure 5As shown, a number of protrusions 102 for reducing the contact area of the cable are provided inside the power pipe body 1; by using the protrusions 102, the contact area between the inner surface of the power pipe body 1 and the cable can be reduced, and the friction between the cable and the inner surface of the power pipe body 1 can be reduced when pulling the cable, facilitating the installation of the cable.

[0027] During the installation process of the present utility model, first, the installation groove 204 on the connection spacer 2 is installed into the installation boss 101 on the power pipe body 1, and the direction of the connection spacer 2 is rotated and adjusted so that the pre-positioning groove 203 in the locking installation groove 202 on the connection spacer 2 is aligned with the pre-positioning groove 203 in the locking installation groove 202 on the power pipe body 1. Then, the pre-limiting boss 301 on the locking sleeve 3 is installed into the pre-positioning groove 203 in the installation grooves 204 on the connection spacer 2 and the power pipe body 1 to pre-fix the connection between the connection spacer 2 and the power pipe body 1, and the locking sleeve 3 is locked by using the locking member 302 to fix the connection between the connection spacer 2 and the power pipe body 1. Install the power pipe body 1 to be connected at the other end of the connection spacer in the above manner.
