Description

Technical Field

[0001] The utility model relates to the technical field of PVC pipes, in particular to a pressure-resistant and wear-resistant PVC electrical pipe. Background Art

[0002] The full name of PVC electrical pipe is "insulated electrical conduit for construction". Generally speaking, it is a white rigid PVC wire pipe that is corrosion-resistant, leak-proof, and used for passing wires. Its main component is polyvinyl chloride, and other ingredients are added to enhance its flame retardant properties, pressure resistance, heat resistance, toughness and ductility.

[0003] Currently, electrical pipes are mainly single-layer PVC pipes, which have poor compressive performance. Some pipes have reinforced structures on the outside or inside, or are double-layer structures that are fixedly connected to each other. However, these pipes are difficult to bend and are only suitable for straight wiring.

[0004] To this end, we propose a pressure-resistant and wear-resistant PVC electrical pipe to solve the above problems. Utility Model Content

[0005] The purpose of the present utility model is to provide a pressure-resistant and wear-resistant PVC electrical pipe to solve the problem raised in the above background technology that the current electrical pipes are mainly single-layer PVC pipes, which have poor pressure resistance. There are also some pipes with reinforced structures on the outside or inside or double-layer structures fixedly connected to each other, but these pipes are difficult to bend and are only suitable for straight wiring.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A pressure-resistant and wear-resistant PVC electrical pipe comprises an outer sleeve and an inner pipe. The outer sleeve is equidistantly wrapped around the outside of the inner pipe. Holes are provided inside the outer sleeve, and the inner pipe passes through the holes. The outer sleeve is semicircular.

[0008] In a further embodiment, the holes are divided into large holes and small holes.

[0009] In a further embodiment, the inner diameters of the large holes and the small holes are both larger than the outer diameter of the inner tube, so that only the bottom of the inner tube contacts the outer tube and the upper part of the inner tube is not subject to any pressure interference.

[0010] In a further embodiment, a metal layer is installed on the curved outer wall surface of the outer sleeve.

[0011] In a further embodiment, vertical through holes are provided on both sides of the arc-shaped outer wall of the outer sleeve, and positioning pins are provided in the through holes.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The electrical tube is divided into an outer tube and an inner tube. The outer tube is semicircular and equidistantly sleeved on the outside of the inner tube. When there is external pressure, the pressure is applied to the outer tube, and the inner tube is not affected by the pressure. When the above conditions are met, the bending of the entire electrical tube is not affected. Moreover, since the hole is larger than the inner tube, more inner tubes can be placed in such an outer tube. When there are more inner tubes, each wire can correspond to an inner tube, so that the wires will not interfere with each other, and the resistance is smaller when the wires are pulled out.

[0017] In the description of the present invention, it should be understood that terms such as "center," "longitudinal," "lateral," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer" indicate positions or locations based on the positions or locations shown in the accompanying drawings. These terms are used solely to facilitate the description of the present invention and to simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0018] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-2 A pressure-resistant and wear-resistant PVC electrical pipe, which includes an outer sleeve 1 and an inner pipe 4. The outer sleeve 1 is equidistantly wrapped around the outside of the inner pipe 4, and the inner pipe 4 is movably inserted, so the position of the outer sleeve 1 outside the inner pipe 4 can be adaptively adjusted, and the gap between the two outer sleeves 1 can be used for bending the entire pipe. The interior of the outer sleeve 1 is provided with a hole, and the inner pipe 4 passes through the hole. The outer sleeve 1 is semicircular. The existence of the outer sleeve 1 increases the pressure area of ​​the upper and lower parts of the pipe. In the past, the entire electrical pipe was round, and it was point contact when under pressure, which made it easy to break.

[0021] Among them, the holes are divided into large holes 2 and small holes 3. The inner diameters of the large holes 2 and the small holes 3 are both larger than the outer diameter of the inner tube 4. In this way, only the bottom of the inner tube 4 will contact the outer sleeve 1, and the upper part of the inner tube 4 will not be disturbed by any pressure. In addition, this design can select inner tubes 4 of different specifications. The inner tube 4 can directly use ordinary single-layer PVC tubes, and because the holes are larger than the inner tube 4, more inner tubes 4 can be placed in such an outer sleeve 1. When there are more inner tubes 4, each wire can correspond to an inner tube 4, so that the wires will not interfere with each other, and the resistance will be smaller when drawing the wires.

[0022] The curved outer wall surface of the outer sleeve 1 is installed with a metal layer 5. When the entire electrical pipe is buried in a wall or underground, metal induction can be used to understand the position of the pipe. At the same time, the metal layer 5 can increase the wear resistance and prevent the pipe from being damaged during drilling. The metal layer 5 can be made of iron, steel and other materials.

[0023] After the wiring is completed, the positioning nails 7 can be inserted into the vertical through-holes 6 on the outer sleeve 1 and drilled into the wall for fixation.

[0024] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0025] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
