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. 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. Each inner tube 2 contains a kind of wire, either a power line or a signal line. The inner tube 2 can be made of ordinary Plastic covered wire can be made of PVC material to tie up the internal wires. There can 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 diameter of the inner tube 2 and the tube body 1.

[0033] Such as figure 1 As shown, the tube body 1 is also provided with an elastic airbag 31 for fixing the inner tube 2 on the inner wall of the tube body 1. The contact parts of the elastic airbag 31 and the inner tube 2 are all made of hard rubber with an isolation surface 32, elastic T...

Embodiment 2

[0045] Such as image 3 As shown, a PVC electrical pipe, compared with the first embodiment, the second embodiment is different from the structure of the holder, the outer surface of the central shaft 51 is provided with threads, and the central shaft 51 is sheathed with A threaded shaft sleeve 54 is provided with a plurality of support rods 53 distributed on the circumference of the shaft sleeve 54. The rotating shaft sleeve 54 can be adjusted in the axial direction by rotating the shaft sleeve 54 to ensure the support rod 53 on the shaft sleeve 54 Able to be transferred to a suitable location. When the cage is produced by processing, the shaft sleeve 54 and the support rod 53 can be processed separately, and then the support rod 53 is welded to the shaft sleeve 54, and a 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 pipelines, in particular to a PVC electrical pipe. Background technique [0002] Electrical bushings have been produced in my country for many years, with a complete variety of models, and generally good quality. Its sales have been soaring along with the real estate industry. Now the ordinary electrical bushings on the market have more and more diversified classifications in terms of performance to adapt to a variety of circuit uses. [0003] However, when wiring the internal walls of our homes and industrial plants, we usually lay the zero live wire for current transmission and separate pipelines for transmitting signals. Because the power of the zero live wire is relatively strong, a certain amount of electromagnetic radiation will be generated. This will cause signal interference to the signal lines, and laying them separately can ensure the signal stability of the signal lines. However, when laying separately, in o...
