[0038] The specific embodiments shown below are intended to be descriptions of various configurations of the subject technology of the present invention, and are not intended to represent the only configuration in which the subject technology of the present invention can be practiced. The specific embodiments include specific details intended to provide a thorough understanding of the subject technology of the present invention. However, it will be clear and obvious to those skilled in the art that the subject technology of the present invention is not limited to the specific details shown herein, and can be practiced without these specific details.

[0039] Reference Figures 1 to 6 As shown, a highly wear-resistant power cable protection tube comprises an inner tube body 1 and an outer tube body 2 sleeved outside the inner tube body 1;

[0040] The outer tube body 2 is plugged with a wear-resistant component 21, and the wear-resistant component 21 is evenly arranged along the circumferential direction of the outer tube body 2, and a part of the wear-resistant component protrudes outward from the outer tube body 2;

[0041] An elastic positioning component 3 for positioning the inner tube body 1 is arranged between the outer tube body 2 and the inner tube body 1. The elastic positioning components 3 are evenly arranged along the circumferential direction of the inner tube body 1, and the elastic positioning components 3 correspond to the wear-resistant components 21 one by one.

[0042] The wear-resistant component 21 includes a seat body 211 inserted into the outer tube body 2, and the seat body 211 is provided with a roller 212, and the roller 212 is rotatably connected to the seat body 211, and the roller 212 protrudes from the outer tube body 2;

[0043] Baffles 22 are provided at both ends of the outer tube body 2, and the baffles 22 are provided with through holes communicating with the inner tube body 1. The roller 212, the seat body 211, the elastic positioning assembly 3 and the inner tube body 1 are all positioned by the baffles 22, and the baffles 22 are fixed to the outer tube body 2 by a detachable connection.

[0044] The baffle 22 can be fixed to the outer tube body 2 by screws. The outer tube body 2 can be made of metal material. The inner wall and the outer wall of the outer tube body 2 should also be coated with corrosion-resistant and rust-proof paint to ensure that the cable protection tube has a longer service life.

[0045] The roller 212 can also be replaced by a ball. When a ball is used, a plurality of balls are evenly arranged along the length direction of the seat body 211. When a ball is used, since a large number of balls need to be arranged, the wear-resistant component 21 is difficult to maintain and the use cost is high. Therefore, the preferred solution is to use the roller 212.

[0046] Reference Figures 1 to 6 As shown, in some embodiments, the outer tube body 2 is provided with a slot 23, and the slot 23 is arranged along the axial direction of the outer tube body 2, and the slot 23 includes a slot body 231 and a clearance slot 232 communicated with the slot body 231, and the width of the slot body 231 is greater than the width of the clearance slot 232, and the seat body 211 includes a positioning plate 2111 matched with the slot body 231 and a vertical plate 2112 extending from the slot body 231 through the clearance slot 232, and the roller 212 is rotatably connected to the vertical plate 2112.

[0047] The more wear-resistant components 21 are set, the less likely it is that external objects will directly contact the outer tube body 2. However, external objects usually have a certain volume. Therefore, the number of wear-resistant components 21 can be reasonably set as needed to reduce the use cost of the cable protection tube.

[0048] Generally, the number of the wear-resistant components 21 may be 10 to 20, which effectively reduces the manufacturing cost of the cable protection tube while making the cable protection tube have better wear resistance.

[0049] Reference Figures 1 to 6 As shown, in some embodiments, the positioning plate 2111 and the vertical plate 2112 are an integrated structure, and an assembly groove cooperating with the roller 212 is provided at one end of the vertical plate 2112 away from the positioning plate 2111, and the cross-sectional shape of the assembly groove is an arc greater than 1 / 2, and a portion of the roller 212 protrudes from the assembly groove.

[0050] The depth of the assembly groove is greater than the diameter of the roller 212. For example, the depth of the assembly groove may be 2 / 3 of the diameter of the roller 212, so that 1 / 3 of the diameter of the roller 212 protrudes from the column, thereby contacting an external object. In addition, the roller 212 and the assembly groove have a high connection strength to prevent the roller 212 from being separated from the assembly groove.

[0051] Lubricating grease is applied between the roller 212 and the assembly groove.

[0052] In some embodiments, the elastic positioning assembly 3 includes an outer top plate 31 in contact with the inner wall of the outer tube body 2 and an inner top plate 32 in contact with the outer wall of the inner tube body 1 , and a support body 33 is provided between the inner top plate 32 and the outer top plate 31 .

[0053] The support body 33 , the outer top plate 31 , and the inner top plate 32 are an integrated structure.

[0054] The outer top plate 31, the inner top plate 32 and the support body 33 can all be made of rubber material, or the support body 33 can be made of metal material, and the inner top plate 32 and the outer top plate 31 can be made of rubber material, such as the support body 33 can be fixed between the inner top plate 32 and the outer top plate 31 by bonding.

[0055] In some embodiments, the width of the outer top plate 31 is not less than the width of the slot body 231 , and the outer top plate 31 is disposed correspondingly to the slot body 231 .

[0056] Reference Figures 1 to 6 As shown, in some embodiments, the outer wall of the inner tube body 1 is provided with positioning ribs 11 , and a positioning groove for positioning the inner top plate 32 is formed between two adjacent positioning ribs 11 .

[0057] The positioning rib 11 and the inner tube body 1 are an integrated structure, and the cross-sectional shape of the positioning rib 11 is a polygon.

[0058] In addition to locating the position of the inner top plate 32, the positioning ribs 11 also improve the strength of the inner tube body 1, making the inner tube body 1 less likely to be damaged or deformed during long-term use, thereby extending the service life of the inner tube body 1.

[0059] The cross-sectional shape of the positioning rib 11 may be rectangular.

[0060] In some embodiments, the support body 33 is disposed corresponding to the vertical plate 2112 , and the thickness of the support body 33 is not less than the thickness of the vertical plate 2112 .

[0061] After the vertical plate 2112 is subjected to the extrusion force, the vertical plate 2112 transmits the extrusion force to the positioning plate 2111, and then the positioning plate 2111 transmits the force to the outer tube body 2. This force may cause damage or deformation of the outer tube body 2. By arranging the support body 33 corresponding to the vertical plate 2112, the support body 33 supports the outer tube body 2 through the outer top plate 31, and the position where the positioning plate 2111 applies the force to the outer tube body 2 will be effectively supported by the support body 33, so that the outer tube body 2 is not easily deformed, thereby extending the service life of the outer tube body 2.

[0062] The above introduces the subject technical solution of the utility model and the corresponding details. It can be understood that the above introduction is only some implementation plans of the subject technical solution of the utility model, and some details can be omitted during the specific implementation.

[0063] In addition, in some embodiments of the above utility model, multiple embodiments may be implemented in combination, and various combination schemes are not listed one by one due to space limitations. Those skilled in the art can freely combine and implement the above embodiments according to needs during specific implementation to obtain a better application experience.

[0064] When implementing the subject technical solution of the utility model, those skilled in the art can obtain other detailed configurations or drawings according to the subject technical solution of the utility model and the drawings. Obviously, these details still fall within the scope covered by the subject technical solution of the utility model without departing from the subject technical solution of the utility model.
