[0039] 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.

[0040] Reference Figures 1 to 6 As shown, a high-strength double-arm cable protection tube comprises a tube body 1, and a protection component 2 for protecting the tube body 1 is arranged outside the tube body 1;

[0041] The cross-sectional shape of the tube body 1 is polygonal, and a placement cavity 11 for placing cables is provided in the tube body 1, and the cross-sectional shape of the placement cavity 11 is circular;

[0042] The protection assembly 2 includes a base 21 supporting the tube body 1, the base 21 is provided with a placement groove 211, a portion of the tube body 1 is located in the placement groove 211, and the cross-sectional shape of the placement groove 211 is semicircular;

[0043] The protection assembly 2 also includes a pressure-bearing seat 22, which is plugged into the base 21. The pressure-bearing seat 22 includes a top plate 221, and the top plate 221 is respectively provided with a first arm 222 and a second arm 223 which are plugged into the base 21. The first arm 222 and the second arm 223 are respectively located on both sides of the tube body 1, and a receiving cavity for receiving the tube body 1 is formed between the first arm 222 and the second arm 223. A part of the tube body 1 is located in the receiving cavity, and the cross-sectional shape of the receiving cavity is semicircular.

[0044] Support ribs 23 are provided between the top plate 221 and the first support arm 222 , and between the top plate and the second support arm 223 , for dispersing the force exerted on the top plate 221 and enclosing the accommodation cavity.

[0045] Take the cable protection tube pre-installed below the ground as an example. Usually, vehicles or other heavy objects on the ground will exert a downward force when passing through the cable protection tube, that is, the cable protection tube bears the downward force. Although the cable protection tube with a circular cross-section shape can evenly disperse the force, the area of ​​the cable protection and the force bearing is small. For example, when a vehicle is directly above the cable protection tube, the highest point of the cable protection tube bears the force, which is prone to stress concentration. In addition, when the cable protection tube is a single layer, the cable protection tube will squeeze the cable after deformation, causing the cable to be easily damaged.

[0046] By setting up a pressure-bearing seat 22, the pressure-bearing seat 22 includes a top plate 221 and a first arm 222 and a second arm 223. The top plate 221 is used to disperse the force. The force borne by the top plate 221 is evenly dispersed on the top plate 221, and then the first arm 222 and the second arm 223 usually transmit the force to the base 21. In fact, when the tube body 1 and the base 21 are a split structure, the tube body 1 does not bear the force, so the tube body 1 is not easily damaged.

[0047] Alternatively, when the tube body 1 and the base 21 are an integrated structure, the tube body 1 is subjected to a smaller force and is not easily damaged.

[0048] Reference Figures 1 to 6 As shown, in some embodiments, a groove is further provided in the placement cavity 11 to reduce the contact area between the side wall of the placement cavity 11 and the cable. The groove is recessed into the side wall of the placement cavity 11, and the groove is evenly arranged on the side wall of the placement cavity 11.

[0049] The grooves are arranged along the axial direction of the placement cavity 11 , or the axial direction of the grooves is perpendicular to the axial direction of the placement cavity 11 , and the grooves are evenly arranged along the axial direction of the placement cavity 11 .

[0050] The placement cavity 11 is used to place cables. The smaller the contact area between the cable and the side wall of the placement cavity 11, the less likely the cable is to wear. Therefore, by providing a groove, the contact area between the cable and the side wall of the placement cavity 11 can be effectively reduced, making it easier to lay the cable.

[0051] In some embodiments, the support rib 23 includes a main rib 231 that is an integral structure with the top plate 221 , and secondary ribs 232 are provided between the main rib 231 and the top plate 221 , and between the main rib 231 and the first arm 222 , and the second arm.

[0052] The number of the main ribs 231 and the auxiliary ribs 232 is not limited and can be freely determined according to the magnitude of the applied force. The greater the number of the main ribs 231 and the auxiliary ribs 232 , the higher the strength of the pressure-bearing seat 22 .

[0053] In some embodiments, a pressure-bearing beam 24 is inserted into the pressure-bearing seat 22 , and the pressure-bearing seat 22 is provided with a socket for inserting the pressure-bearing beam 24 .

[0054] The top plate 221 , the main ribs 231 , and the secondary ribs 232 surround the insertion hole.

[0055] The arrangement of the pressure-bearing beam 24 further improves the strength of the pressure-bearing seat 22. The insertion hole is surrounded by the top plate 221, the main ribs 231, and the auxiliary ribs 232, which simplifies the structure of the pressure-bearing seat 22 and reduces the manufacturing cost of the pressure-bearing seat 22.

[0056] Reference Figures 1 to 6 As shown, in some embodiments, the pressure bearing seat 22 is further provided with a heat dissipation groove 25, and the heat dissipation groove 25 connects the accommodating cavity with the outside.

[0057] Heat may be generated during the operation of the cable, which may cause aging of the insulation layer of the cable. Therefore, by providing the heat dissipation slot 25, the heat generated by the cable can be quickly dissipated, so that the cable can operate within a reasonable temperature range, thereby extending the service life of the cable.

[0058] In some embodiments, the base 21 is provided with a positioning groove 212 for positioning the pressure seat 22. The base 21 includes a bottom plate 213. The positioning groove 212 is provided on the bottom plate 213. There are two positioning grooves 212. The first support arm 222 and the second support arm 223 respectively cooperate with an independent positioning groove 212.

[0059] The bottom plate 213 is provided with convex plates 214 on both sides of the positioning groove 212 , respectively. The convex plates 214 and the bottom plate 213 are an integrated structure.

[0060] The provision of the protruding plate 214 allows the positioning groove 212 to have a deeper depth, thereby allowing the pressure-bearing seat 22 and the base 21 to have a higher connection strength.

[0061] In some embodiments, the bottom plate 213 is further provided with ribs 215 , the lower ends of the ribs 215 are an integral structure with the bottom plate 213 , and the upper ends of the ribs 215 are in contact with the first support arm 222 and the second support arm 223 , respectively.

[0062] The number of the support ribs 23 is not limited and can be reasonably determined according to needs. The greater the number of the support ribs 23 , the higher the strength of the base 21 .

[0063] The tube body 1 and the base 21 are an integrated structure, or the tube body 1 is installed on the base 21. The tube body 1 can be placed on the base 21, that is, the tube body 1 can only be in contact with the base 21 but not fixed.

[0064] 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.

[0065] 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.

[0066] 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.
