The pipe comprises a pipe body, wherein the outer wall surface of the pipe body is a smooth surface, a contact structure convenient for threading is arranged on the inner wall surface of the pipe body, the contact structure comprises a group of bulges, and the bulges are circumferentially arranged along the central axis of the pipe body. The utility model discloses an inner wall at the tubular product main part sets up a set of arch, utilizes the curved surface structure of protruding lateral surface, can convert the sliding friction between electric wire and the pipeline inner wall into "roll" friction to a certain extent between the arch that sets up on electric wire and the pipeline inner wall, has reduced the frictional force that the electric wire received when the threading, has improved the efficiency of construction and the construction quality of threading construction effectively.
Description
Technical Field
The utility model belongs to the technical field of electrician's sheath pipeline, concretely relates to novel electrician's sheath pipeline.
Background
In the installation of home covert engineering systems, the following systems are mainly routinely included: water supply system, drainage system and electrician's system. The electrical system mainly comprises: electrical bushings, pipe fittings, as well as electrical wires, switches, etc.
In the process of engineering installation of an electrician system, the method mainly comprises the following steps: slotting, pipe distribution and threading. The most difficult is the threading process during the construction process. Threading difficulty and threading labor are main problems in the prior threading process.
The existing electrician sleeve is mainly a product with smooth inner and outer surfaces, the friction between an electric wire and the inner wall of a wire tube is generally sliding friction in the wire pulling process, and the friction is large, so that the threading is difficult.
SUMMERY OF THE UTILITY MODEL
To the above-mentioned problem that exists among the prior art, the utility model aims to provide a when can reducing the threading, the electrician's sheath pipeline of frictional force between electric wire and the pipeline improves threading efficiency and threading quality.
The utility model provides a following technical scheme: the utility model provides a novel electrician's sheath pipeline, includes the tubular product main part, and the outer wall of tubular product main part is smooth surface, is equipped with the contact structure of the threading of being convenient for on the internal face of tubular product main part, the contact structure includes a set of arch, and a set of arch is the circumference around the central axis of tubular product main part and arranges.
Further, the bulge is arranged along the axial direction of the pipe main body and is in a curve shape.
Furthermore, a group of the bulges are continuously arranged and combined to form a contact structure.
Furthermore, a group of the protrusions are arranged at intervals and combined to form a contact structure.
Furthermore, the outer side surface of the protrusion is a curved surface.
Further, the curved surface is of a cambered surface structure.
Through adopting above-mentioned technique, compare with prior art, the beneficial effects of the utility model are as follows:
in the utility model, a group of bulges are arranged on the inner wall of the pipe main body, and the curved surface structure of the outer side surface of the bulges is utilized, so that the contact area between the electric wire and the inner wall of the pipeline can be reduced, and meanwhile, the sliding friction between the electric wire and the inner wall of the pipeline is converted into rolling friction between the electric wire and the bulges arranged on the inner wall of the pipeline to a certain extent, the friction force of the electric wire during threading is reduced, the damage to the electric wire is reduced, and the construction efficiency and the construction quality of threading construction are effectively improved; meanwhile, the bulges are in a curve shape, so that the pipe stay wire can be prevented from being clamped in the gaps between the adjacent bulges.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments of the specification. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example one
Referring to fig. 1-2, a novel electrical protective sleeve pipeline includes a pipe body 1, an outer wall of the pipe body 1 is a smooth surface, a set of protrusions 2 is disposed on an inner wall of the pipe body 1, and the protrusions 2 are disposed on the inner wall along a central axis of the pipe body 1. The outer side surface of the bulge 2 is of a smooth cambered surface structure, the whole bulge is in a curve shape, and the bulge can also be of a smooth curved surface structure in other shapes.
A group of bulges 2 are circumferentially and continuously arranged along the central axis of the pipe body 1 and combined to form a contact structure convenient for threading wires.
Example two
Referring to fig. 3, a novel electrical sheath pipeline includes a tube main body 1, an outer wall of the tube main body 1 is a smooth surface, a set of protrusions 2 is disposed on an inner wall of the tube main body 1, and the protrusions 2 are disposed on the inner wall along a central axis of the tube main body 1. The outer side surface of the bulge 2 is of a smooth cambered surface structure, and the whole bulge is of a curve shape and can also be of a smooth curved surface structure with other shapes.
A group of bulges 2 are arranged along the central axis of the pipe main body 1 at intervals and combined to form a contact structure convenient for threading the electric wire
In the threading process of the electrical sheath pipeline in the first embodiment and the second embodiment, the electric wire passes through the protrusion 2 on the inner wall of the pipe main body 1, and rolling friction is formed between the electric wire and the protrusion 2 to a certain extent, so that the friction force of the electric wire during threading is reduced, and the construction efficiency and the construction quality of threading construction are effectively improved.
Under the condition that the pipe wall is a plane and the pulling force of the pull wire is the same, the friction force of any contact surface of the electric wire and the inner wall of the pipe is the same, the wire is a continuous body, and the larger the contact surface is, each point contact on the wire can generate the friction force; in the first and second embodiments, the total positive pressure value in the wire pulling process is reduced by reducing the contact points/surfaces between the wires and the inner wall of the tube, so that the friction force is reduced, and the convenience of wire pulling is realized.
