Problems solved by technology

However, when laying separately, in order not to interfere with each other, it is necessary to keep a certain distance between the two, which will occupy a relatively large space, and at the same time, the cost of construction is relatively high.

Embodiment 1

[0032] A PVC electrical pipe includes a pipe body 1 made of PVC material, the pipe body 1 is installed inside or outside a wall, and the cross section of the entire pipe body 1 presents a circular structure. The tube body 1 is provided with a plurality of inner tubes 2 for accommodating power lines or signal lines, and each inner tube 2 contains a kind of electric wire, or is a power line, or is a signal line, and the inner tube 2 can be made of an ordinary Plastic covered wire, which can be made of PVC material, binds the wires inside. There may be about three or four inner tubes 2 on each tube body 1 , and the number of inner tubes 2 is determined according to the inner diameters of the inner tubes 2 and the tube body 1 .

[0033] Such as figure 1 As shown, the tube body 1 is also provided with an elastic air bag 31 for fixing the inner tube 2 on the inner wall of the tube body 1, and the contact parts between the elastic air bag 31 and the inner tube 2 are all made of hard...

Embodiment 2

[0045] Such as image 3 As shown, a PVC electrical pipe, compared with Embodiment 1, the difference of Embodiment 2 lies in the structure of the cage, the outer surface of the central shaft 51 is provided with threads, and the outer surface of the central shaft 51 is provided with a A threaded shaft sleeve 54, a plurality of support rods 53 are distributed on the circumference of the shaft sleeve 54, and the rotation of the shaft sleeve 54 can be adjusted axially by rotating the shaft sleeve 54 to ensure that the support rods 53 on the shaft sleeve 54 able to move to a suitable location. When processing to produce the cage, the shaft sleeve 54 and the support rod 53 can be processed separately, and then the support rod 53 is welded on the shaft sleeve 54, and the support rod 53 of the same specification is welded on each shaft sleeve 54. The number of support rods 53 can be increased or decreased according to actual needs.

Abstract

The invention discloses a PVC electrical tube. According to the main points of the technical scheme, the PVC electrical tube comprises a tube body, wherein a plurality of inner tubes for accommodating power lines or signal lines are arranged in the tube body; an elastic airbag for fixing the inner tubes on the inner wall of the tube body is also arranged in the tube body; the contact parts of the elastic airbag and the inner tubes all are isolating surfaces made of hard rubber; and metal nets for electromagnetic shielding are arranged on the outer wall of the tube body and in the isolating surfaces. The plurality of inner tubes with different functions can be effectively separated after the structure of the elastic airbag is inflated, so that the isolating surfaces wrap the overall PVC electrical tube and wrap the outer wall of the tube body in fit; the condition that individual signal isolation can be carried out on each inner tube is ensured; and signal interference among the inner tubes is avoided. By the structure of the elastic airbag, fixation of the inner tubes can be ensured while the inner tubes are isolated; and the inner tubes contradict the airbag, so that circuit power adjustment, signal shunting and the like are also facilitated after the inner tubes are used for a period of time.

Description

technical field [0001] The invention relates to the field of pipes, in particular to a PVC electrical pipe. Background technique [0002] Electrical bushings have been produced in my country for many years, with a complete range of models and generally good quality. Its sales volume has been soaring along with the real estate industry. Now the common electrical bushings on the market are more and more diversified in terms of performance, so as to adapt to the use of various circuits. [0003] However, when we wire the interior walls of our homes and industrial plants, we usually lay the zero-fire wire used to transmit current and the separate pipeline for transmitting signals. Due to the strong power of the zero-fire wire, it will generate certain electromagnetic radiation. As a result, signal interference will be generated on the signal line, so laying them separately can ensure the signal stability of the signal line. However, when laying separately, in order not to inte...
