Description

Technical Field

[0001] This utility model relates to the field of electrical conduit technology, and in particular to an electrical conduit. Background Technology

[0002] Electrical conduit is a commonly used protective material for electrical wires during building wiring. It is typically installed concealed in normal indoor environments or in various locations such as high-temperature, dusty, humid, vibrating, or fire-prone areas. During wiring, wires are threaded through the conduit to prevent direct contact with the external environment, thus protecting the cables. Currently, indoor wiring lengths are often large, and the electrical conduit used is generally quite long. The length of the conduit used is also uncertain, making it inconvenient to connect conduits in series. The long conduit length increases the difficulty of threading the wires. Sometimes, the cables are too crowded, leading to tangling and potential interference between cables or signal lines. Removing, replacing, and repairing cables also presents difficulties, impacting wiring efficiency. Given the technical shortcomings of existing electrical conduit technology, there is a need to research a more rational and reasonable type of conduit to solve these problems. Utility Model Content The purpose of this utility model is to provide an electrical conduit that enables rapid connection and assembly, as well as wire threading and conduit installation.

Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of this utility model, and these aspects can be achieved even without these specific details.

[0014] Combination Figure 1 and Figure 2 As shown, this utility model provides an electrical conduit, which includes a tube body 1 and connecting sleeves 2 sleeved on both ends of the tube body 1. The tube body 1 and connecting sleeves 2 are made of CPVC, PVC SG5 resin or PP material. The thickness of the tube body 1 is 1.5-3mm. A snap-fit ​​ring 10 is provided on the outer peripheral wall of one end and / or both ends of the tube body 1. The outer wall of the connecting sleeve 2 is open along the axial direction. An annular groove 20 for receiving the snap-fit ​​ring 10 is provided on the inner wall near the two ends of the connecting sleeve 2. A first fitting edge 21 and a second fitting edge 22 are respectively provided on the two open edges of the connecting sleeve 2 along the axial direction, which are symmetrically fitted. One or more rows of insertion holes 23 are provided on the surface of the first fitting edge 21 along the axial direction. An insertion protrusion 24 that matches and is inserted into the insertion hole 23 is provided on the side wall of the second fitting edge 22 along the axial direction. An extension rod extending along the axial direction is provided on the outer wall of the connecting sleeve 2. The reinforcing rib 25 enhances the toughness of the connecting sleeve 2. When laying electrical conduits, the cable is first passed from one end of the conduit 1 to the other, and then connected to the end of the conduit 1 through the opening of the connecting sleeve 2, allowing adjacent conduits 1 to be connected in series through the connecting sleeve 2. The retaining ring 10 on the end of the conduit 1 is restricted within the annular groove 20 on the inner wall of the connecting sleeve 2. Then, the insertion protrusion 24 on the second mating edge 22 of the connecting sleeve 2 is pressed into the insertion hole 23. By setting multiple rows of insertion holes 23, the tightness of the connection between the connecting sleeve 2 and the adjacent conduit 1 can be adjusted or restricted as needed. At the same time, it can quickly connect two adjacent conduits in series, improving the speed and efficiency of wire threading and conduit laying.

[0015] In this utility model, combined with Figure 1 and Figure 3 As shown, one or more wire-passing channels 11 extending along the axis of the pipe body 1 are provided on the inner wall of the pipe body 1. As the preferred embodiment of this utility model, three equally spaced wire-passing channels 11 extending along the axis of the pipe body 1 are provided on the inner wall of the pipe body 1. When threading the cable, the cable is threaded through the wire-passing channel 11 of the pipe body 1 and the main channel of the pipe body 1 respectively. Threading the cable through each wire-passing channel 11 and the main channel of the pipe body 1 can avoid the cable from getting tangled and can also prevent signal interference between the cables.

[0016] In utility models, combined with Figure 1 and Figure 3 As shown, the inner wall of the pipe body 1 is provided with a slip-enhancing coating 100, which is an epoxy resin layer. This makes the inner wall of the pipe body 1 smoother, reduces wire threading resistance, and improves the corrosion resistance, weather resistance, and electrical insulation of the inner wall. An anti-oxidation coating 101 is provided on the outer wall of the pipe body 1. This anti-oxidation coating is made of polytetrafluoroethylene (PTFE) and improves the high-temperature resistance, low-temperature resistance, and corrosion resistance of the electrical conduit. It reduces the impact of environmental factors on the electrical conduit, improves its toughness, and prevents the conduit from easily breaking after impact. A shielding layer 102 with a thickness of 0.5-1 mm is provided between the outer wall of the pipe body 1 and the anti-oxidation coating 101.

[0017] In this utility model, combined with Figure 1 and Figure 3 As shown, the shielding layer 102 consists of an inner shielding layer 102a and an outer shielding layer 102b arranged outward from the outer wall of the pipe body 1. The inner shielding layer 102a is a metal shielding mesh, which not only improves the strength of the pipe body and prevents external interference signals from interfering with the cables inside the pipe body 1, but also enhances the toughness, high temperature resistance, and flame retardant properties of the pipe body. The outer shielding layer 102b is a shielding layer made of glass fiber material, which is alkali-free chopped fiber with a length of 0.5-2 mm and a diameter of 10-50 μm. Glass fiber material can improve the flexibility of the electrical conduit while ensuring the strength and toughness of the pipe material.

[0018] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
