[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the utility model.

[0020] The utility model provides a technical solution: As Figures 1 to 4As shown in the figure, in this embodiment, a high-strength modified polyvinyl chloride cable protection pipe includes a protection pipe body 1. One end of the protection pipe body 1 is fixedly installed with a connector 2, and the other end of the protection pipe body 1 is provided with a connection hole 3. The connection hole 3 is slidably fitted with the connector 2. A plurality of limiting plates 4 are fixedly connected to the outer wall of the connector 2, and a plurality of limiting grooves 5 are provided on the inner wall of the connection hole 3. The plurality of limiting plates 4 are arranged in a circular array, and the plurality of limiting grooves 5 respectively correspond to the plurality of limiting plates 4 one by one, and the limiting groove 5 is slidably fitted with the limiting plate 4. A fixing mechanism is further provided between the connection hole 3 and the connector 2. The fixing mechanism is composed of a clamping block 9, a movable plate 10 and a spring 11.

[0021] During use, insert the connector 2 at one end of a protection pipe body 1 into the connection hole 3 at one end of another protection pipe body 1. The sliding fit between the limiting groove 5 and the limiting plate 4 can position the two protection pipe bodies 1 and ensure that there is no relative rotation between the two protection pipe bodies 1. When the connector 2 is completely inserted into the connection hole 3, the fixing mechanism can fix the connector 2 and the connection hole 3 together.

[0022] Among them, a plurality of movable grooves 12 are provided inside the connector 2. The plurality of movable grooves 12 respectively correspond to the plurality of limiting plates 4 one by one. A movable plate 10 is slidably installed in the movable groove 12. A spring 11 is fixedly connected between the bottom of the movable plate 10 and the inner cavity bottom of the movable groove 12. The upper end of the movable plate 10 is fixedly connected with a clamping block 9. The clamping block 9 penetrates the top wall of the inner cavity of the movable groove 12 and is located outside the connector 2. A plurality of clamping grooves 6 are provided on the inner wall of the connection hole 3. The plurality of clamping grooves 6 respectively correspond to the plurality of clamping blocks 9 one by one, and the clamping block 9 is slidably fitted with the clamping groove 6.

[0023] Among them, the end face of the clamping block 9 away from the protection pipe body 1 is inclined.

[0024] With such a setting, when the connector 2 is inserted into the connection hole 3, the clamping block 9 can be squeezed into the movable groove 12 by the inner wall of the connection hole 3.

[0025] Among them, the end of the clamping groove 6 extends to the outer wall of the protection pipe body 1.

[0026] With such a setting, when disassembling the two connected protection pipe bodies 1, the clamping block 9 in the clamping groove 6 can be pressed down outside the protection pipe body 1.

[0027] Among them, a plurality of anti-abrasion components are provided on the inner wall of the protection pipe body 1. The plurality of anti-abrasion components are arranged in a straight array. The anti-abrasion component is composed of a spherical groove 7 and a ball 8. The plurality of spherical grooves 7 are arranged in a circular array on the inner wall of the protection pipe body 1, and a ball 8 is arranged in the spherical groove 7.

[0028] With such a setting, when the cable is inserted into the interior of the protection tube body 1, the ball bearings 8 can protect the cable, so that the outer surface of the cable will not directly rub against the inner wall of the protection tube body 1, thereby avoiding abrasion of the outer surface of the cable.

[0029] The utility model provides a high-strength modified polyvinyl chloride cable protection tube, and the specific working principle is as follows:

[0030] During use, insert the connector 2 at one end of a protection tube body 1 into the connection hole 3 at one end of another protection tube body 1. The sliding fit between the limit groove 5 and the limit plate 4 can position the two protection tube bodies 1, ensuring that there is no relative rotation between the two protection tube bodies 1. When the connector 2 is inserted into the connection hole 3, the clamping block 9 will be squeezed into the movable groove 12 by the inner wall of the connection hole 3, thereby squeezing the spring 11. When the connector 2 is completely inserted into the connection hole 3, the clamping block 9 on the connector 2 will just align with the clamping groove 6 in the connection hole 3. Under the action of the spring 11 restoring its deformation, the clamping block 9 will be inserted into the clamping groove 6, thereby fixing the two protection tube bodies 1 together. At the same time, by providing ball bearings 8 on the inner wall of the protection tube body 1, when the cable is inserted into the interior of the protection tube body 1, the ball bearings 8 can protect the cable, so that the outer surface of the cable will not directly rub against the inner wall of the protection tube body 1, thereby avoiding abrasion of the outer surface of the cable.

[0031] Among them, the protection tube body is made of modified polyvinyl chloride material, which has the characteristic of high strength and can provide good protection for the cable.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
