Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipes, in particular to an electrical casing. Background Art
[0002] Electrical conduit, also known as cable conduit or protective tube, is a commonly used material in building electrical installation projects. It is mainly used to protect wires or cables, ensuring that they are protected from physical damage, moisture, corrosion and other factors when installed inside or outside a building, and maintaining the electrical insulation performance of the line.
[0003] When laying the electrical conduit, it is necessary to first make a groove on the wall along the wiring direction, then bury the electrical conduit in the groove, and finally seal the groove with concrete and other materials to bury the electrical conduit in the wall. However, in actual operation, since the outer surface of the electrical conduit is relatively smooth, the adhesion between the concrete and the outer surface of the electrical conduit is poor, resulting in the concrete easily sliding off the surface of the electrical conduit when filling the groove, causing great inconvenience to the actual construction; and since the adhesion between the concrete material and the electrical conduit is poor, over time, the concrete is easy to peel off from the surface of the electrical conduit, and the concrete is easy to produce hollowing and cracking. Summary of the invention
[0004] The utility model aims to solve the deficiencies in the prior art and provide an electrical bushing.
[0005] The purpose of the utility model is achieved through the following technical scheme: an electrical conduit, comprising a tube body and an additional strip, the outer side of the tube body is provided with an embedding groove and a groove, the embedding groove is arranged along the axial direction of the tube body, the additional strip comprises a strip body, one side of the strip body is provided with a plurality of protrusions, and the additional strip is embedded in the embedding groove.
[0006] In the utility model, the additional strip can be selectively installed in the embedded groove on the electrical sleeve. When the additional strip is embedded in the embedded groove, the protrusion on the additional strip protrudes toward the outside of the tube body; when the concrete is filled into the groove on the wall, the protrusion can be buried in the concrete, and the concrete can be effectively attached to the electrical sleeve, which greatly improves the adhesion between the concrete and the electrical sleeve, effectively avoids the concrete from falling off the tube body during the construction process, and facilitates the construction operation; and after the concrete solidifies, the protrusion can be firmly embedded in the concrete and firmly combined with the concrete, effectively avoiding the phenomenon of peeling between the concrete and the electrical sleeve, and reducing the problem of hollowing and cracking of the concrete. The groove arranged on the outside of the tube body increases the surface connection of the outside of the tube body, thereby increasing the contact area between the concrete and the electrical sleeve, which is conducive to improving the adhesion of the concrete on the electrical sleeve.
[0007] Preferably, a reinforcement portion protruding radially outward from the tube body is provided on the outer side of the tube body, and the embedding groove is provided on the reinforcement portion.
[0008] Preferably, the protrusions are cylindrical, and the protrusions are arranged along the length direction of the strip.
[0009] Preferably, the cross-sections of the embedding groove and the strip-shaped body are both rectangular, and the strip-shaped body and the embedding groove have an interference fit.
[0010] Preferably, four embedding grooves are evenly arranged on the outer side of the tube body, 2-4 grooves are arranged between two adjacent embedding grooves, and the cross section of the groove is in the shape of an arc.
[0011] Preferably, the material of the tube body is PVC or PE.
[0012] The beneficial effects of the utility model are as follows: in the utility model, after the additional strip is embedded in the embedding groove, the protrusion on the additional strip protrudes toward the outside of the tube body; when filling concrete into the groove body on the wall, the protrusion can be buried in the concrete, and the concrete can be effectively attached to the electrical sleeve, which greatly improves the adhesion between the concrete and the electrical sleeve, effectively avoids the concrete from falling off the tube body during construction, and facilitates the construction operation; and after the concrete solidifies, the protrusion can be firmly embedded in the concrete and firmly combined with the concrete, effectively avoiding the peeling phenomenon between the concrete and the electrical sleeve, and reducing the problem of hollowing and cracking of the concrete.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.
[0017] like Figure 1 to Figure 2 As shown, an electrical conduit comprises a tube body 1 and an additional strip 2. An embedding groove 12 and a groove 13 are provided on the outer side of the tube body 1. The embedding groove 12 is arranged along the axial direction of the tube body 1. The additional strip 2 comprises a strip body 21. A plurality of protrusions 22 are provided on one side of the strip body 21. The additional strip 2 is embedded in the embedding groove 12.
[0018] The protrusion 22 is a cylinder, and the protrusion 22 is arranged along the length direction of the strip 21. The cross sections of the embedding groove 12 and the strip 21 are both rectangular, and the strip 21 is interference fit with the embedding groove 12. When the additional strip 2 is installed on the pipe body 1, the additional strip can be bonded by glue to improve the bonding between the additional strip and the pipe body 1.
[0019] In the utility model, the additional strip 2 can be selectively installed in the embedding groove 12 on the electrical sleeve. When the additional strip is embedded in the embedding groove 12, the protrusion 22 on the additional strip protrudes toward the outside of the pipe body 1; when filling concrete into the groove on the wall, the protrusion 22 can be buried in the concrete, and the concrete can be effectively attached to the electrical sleeve, which greatly improves the adhesion between the concrete and the electrical sleeve, effectively avoids the concrete from falling off from the pipe body 1 during the construction process, and facilitates the construction operation; and after the concrete solidifies, the protrusion 22 can be firmly embedded in the concrete and firmly combined with the concrete, effectively avoiding the phenomenon of peeling between the concrete and the electrical sleeve, and reducing the problem of hollowing and cracking of the concrete; the groove 13 arranged on the outside of the pipe body 1 increases the surface connection of the outside of the pipe body 1, thereby increasing the contact area between the concrete and the electrical sleeve, which is beneficial to improving the adhesion of the concrete on the electrical sleeve.
[0020] The outer side of the tube body 1 is provided with a reinforcement part 11 protruding radially outwardly of the tube body 1, and the embedding groove 12 is arranged on the reinforcement part 11. The reinforcement part 11 protrudes radially outwardly of the tube body 1, and the tube wall is thicker at the position where the reinforcement part 11 is located. The embedding groove 12 is arranged on the reinforcement part 11, which can effectively compensate for the decrease in the strength of the tube body 1 caused by the provision of the embedding groove 12.
[0021] The number of the embedded grooves 12 and grooves 13 arranged on the outer side of the tube body 1 can be determined according to actual needs. In this embodiment, four embedded grooves 12 are evenly arranged on the outer side of the tube body 1, and 2-4 grooves 13 are arranged between two adjacent embedded grooves 12, and the cross section of the groove 13 is arc-shaped.
[0022] The material of the tube body 1 is PVC or PE.
