Description

Technical Field

[0001] This utility model relates to the field of cable protection technology, specifically to a cable protection pipe. Background Technology

[0002] Snake-skin conduits typically refer to flexible hoses with a snake-skin-like appearance and properties. In factories and mines, during the installation of electrical equipment and thermal control systems, terminal cables are often encased in snake-skin conduits for protection. However, existing snake-skin conduits lack expansion joints, preventing them from connecting properly to the tightening nuts of waterproof cable joints. This allows leaks of liquids or rainwater to seep into the electrical thermal control equipment through the gap between the conduit and the ordinary joint, leading to unsafe and unreliable operation of the equipment. Summary of the Invention

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the defects in the prior art and thus provide a cable protection pipe.

[0004] A cable protection pipe includes: a telescopic sleeve, a pipe body, and a tightening nut; the pipe body has a spiral protrusion; the telescopic sleeve includes a flared tube and a straight pipe section; the tightening nut is fixed inside the flared tube; a spiral groove is provided inside the straight pipe section, and the spiral groove cooperates with the spiral protrusion; the straight pipe section is fixed on the pipe body, and the flared tube is located on the outside of the pipe body.

[0005] Furthermore, the tightening nut is the same as that used on waterproof cable connectors. Furthermore, the flared tube has a fixing groove that matches the shape of the tightening nut. Furthermore, the tube body has a uniform thickness, and the inner side of the spiral protrusion is a spiral groove. Furthermore, the spiral protrusions at both ends of the tube body are separated by a straight section in the middle. Furthermore, the length of the straight section is 5-10 cm. Furthermore, there are two telescopic sleeves located at both ends of the tube body.

[0006] Furthermore, the thickness of the tube body is 2-6 mm. Furthermore, the length of the straight tube section is 2-3 times the length of the trumpet tube.

[0007] The technical solution of this utility model has the following advantages:

[0008] This invention features a telescopic sleeve on the outside of a conduit, with a spiral groove inside. Rotating the sleeve counter-clockwise allows it to be unscrewed from the conduit. A tightening nut can be placed in the flared opening, and this tightening nut rotates when the sleeve is turned counter-clockwise, effectively tightening the waterproof cable connector. Simultaneously, the telescopic sleeve fits over the waterproof cable connector. This allows the telescopic sleeve to be used with waterproof cable connectors, enabling tight connection with thermal control equipment and electrical equipment. It effectively protects the cable inside the conduit and improves cable insulation strength. This device is simple to install, has a long maintenance cycle, and effectively reduces the intrusion of leaking liquids or rainwater into electrical and thermal control equipment through the gap between the conduit and the waterproof cable connector, thus ensuring safe and reliable equipment operation.

[0016] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0018] Example 1

[0019] like Figure 1-4 A cable protection pipe includes: a telescopic sleeve 1, a pipe body 2, and a tightening nut 3; the pipe body 2 has a spiral protrusion 21; the telescopic sleeve 1 includes a flared tube 11 and a straight pipe section 12; the tightening nut 3 is fixed inside the flared tube 11; a spiral groove 13 is provided inside the straight pipe section 12, and the spiral groove 13 cooperates with the spiral protrusion 21; the straight pipe section 12 is fixed on the pipe body 2, and the flared tube 11 is located at the outer end of the pipe body 2.

[0020] Furthermore, the tightening nut 3 is the same type as the nut on a waterproof cable connector, or the same type as the nut on a waterproof cable connector. Waterproof cable connectors are mature existing technology and are not the focus of this invention; their specific structures are also mature existing technology, therefore their specific structures will not be described. This will not result in insufficient disclosure for those skilled in the art.

[0021] Furthermore, the horn tube 11 is provided with a fixing groove 14 that matches the shape of the tightening nut 3. Furthermore, the tube body 2 has a uniform thickness, and the inner side of the spiral protrusion 21 is a spiral groove. Furthermore, the length of the straight tube section is 5-10 cm. Furthermore, there are two telescopic sleeves 1, located at both ends of the tube body 2. Preferably, the length of the straight tube section 12 is 2-3 times the length of the horn tube 11. Preferably, the thickness of the tube body 2 is 2-6 mm, and it is made of snakeskin tubing. Preferably, the cavity of the fixing groove 14 is hexagonal, and this structure can be the same as the shape of most waterproof cable connector nuts in the prior art. Different models of telescopic sleeves 1 can be produced, the specific difference being the structure of the fixing groove 14. The size of the fixing groove 14 matches the shape of commonly used waterproof cable connector nuts, facilitating selection during operation.

[0022] In one embodiment, the two ends of the pipe body 2 are provided with spiral protrusions 21, and the middle pipe section is a straight pipe, which can reduce the processing cost.

[0023] In one embodiment, the outer side of the fixing groove 14 is 3-5 cm away from the outer side of the horn tube 11; preferably, the distance between the outer side of the fixing groove 14 and the outer side of the horn tube 11 is the same as the distance between the outer side of the nut of the waterproof cable connector and the surface of the electrical equipment in the prior art. In this way, during use, the outer side of the horn tube 11 can contact the surface of the electrical equipment, allowing for better sealing.

[0024] In one embodiment, the horn tube is configured as a hexagonal horn, which facilitates tightening and fixing.

[0025] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
