Description

Technical Field

[0001] The utility model relates to the technical field of PVC pipe fittings, in particular to a sun-proof and anti-aging PVC pipe fitting. Background Art

[0002] PVC pipe (divided into PVC-U pipe, PVC-M pipe and PVC-O pipe) is a rigid polyvinyl chloride pipe, which is made of polyvinyl chloride resin and stabilizer, lubricant, etc. and is extruded by hot pressing. It is the earliest plastic pipe material developed and applied.

[0003] After searching, it was found that a sun-proof and anti-aging plastic pipe was disclosed in the Chinese Utility Model Patent Publication No. CN212509846U. By brushing a layer of black plastic primer on the outer surface of the frosted layer and then brushing a layer of white anti-corrosion paint, it can block light and prevent ultraviolet radiation, and can also reduce light transmittance and prevent bacteria from growing. However, the existing PVC pipe fittings lack certain compressive resistance and are easily deformed under pressure. The outermost layer is easily worn and damaged, and is integrated with the pipe fittings. After wear and damage, it needs to be replaced as a whole, increasing the cost of maintenance and replacement. Therefore, a PVC pipe fitting with compressive resistance and wear resistance is needed. Utility Model Content

[0004] The main purpose of the utility model is to provide a sun-proof and anti-aging PVC pipe fitting, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A sun-proof and anti-aging PVC pipe fitting comprises a pipe body, an outer surface of which is fixedly connected to a heat preservation layer, an outer surface of which is fixedly connected to a heat insulation layer, an outer surface of which is fixedly connected to a support layer, and an outer surface of which is fixedly connected to an elastic pressure-resistant layer.

[0007] In order to achieve the effect of making PVC pipe fittings have certain pressure resistance, as a sun-proof and anti-aging PVC pipe fitting of the utility model, the elastic pressure-resistant layer includes an inner layer, the outer surface of the inner layer is fixedly connected to a pressure-resistant column, and one end of the pressure-resistant column is fixedly connected to the outer layer.

[0008] In order to prevent the pipe from cracking, as a sun-proof and anti-aging PVC pipe of the utility model, the outer surface of the elastic pressure-resistant layer is fixedly connected with a network layer, and the network layer is made of a metal wire mesh.

[0009] In order to achieve the effect of ensuring the sun protection performance of the pipe fittings, as a sun-proof and anti-aging PVC pipe fitting of the utility model, the outer surface of the network layer is fixedly connected with an inner sun protection layer, and the material of the inner sun protection layer is fluororesin.

[0010] In order to improve the sun protection performance of the pipe fittings, as a sun-proof and anti-aging PVC pipe fitting of the utility model, the outer surface of the inner sun protection layer is fixedly connected to the outer sun protection layer, and the outer surface of the outer sun protection layer is fixedly connected to wear-resistant protrusions.

[0011] In order to facilitate the installation and removal of the outer sunscreen protective layer, as a sunscreen and anti-aging PVC pipe fitting of the utility model, a card groove is opened on the outer surface of the inner sunscreen protective layer, and a card strip is fixedly connected to the inner wall of the outer sunscreen protective layer.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The sun-proof and anti-aging PVC pipe fittings are provided with a support layer, an elastic pressure-resistant layer, an inner layer, pressure-resistant columns and an outer layer. The elastic pressure-resistant layer is mainly the pressure-resistant columns distributed and arranged between the inner layer and the outer layer. The pressure-resistant columns cooperate with the support layer made of fiber and the network layer made of metal mesh to effectively improve the pressure resistance of the pipe fittings. The elastic pressure-resistant layer and the support layer can not only improve the pressure-bearing performance of the pipe fittings, but also improve the strength of the pipe fittings with the assistance of the network layer. When the pipe fittings are under pressure, they will not be completely deformed, so that the pipe fittings have pressure resistance and the normal use of the pipe fittings is guaranteed.

[0014] 2. The sun-proof and anti-aging PVC pipe fittings have an inner sun-proof layer, an outer sun-proof protective layer, wear-resistant convex points, slots and clips. The wear-resistant convex points distributed on the outer surface of the outer sun-proof protective layer can effectively improve the wear resistance of the pipe fittings and avoid direct wear on the pipe fittings. At the same time, the outer sun-proof protective layer is inserted into the slot of the inner sun-proof layer through the clips to complete the installation. After the outer sun-proof protective layer is severely worn and damaged, only the outermost layer can be replaced without replacing the entire pipe fitting, thereby reducing maintenance costs.

The elastic pressure-resistant layer 5 is mainly the pressure-resistant columns 502 distributed and arranged between the inner layer 501 and the outer layer 503. The pressure-resistant columns 502 cooperate with the support layer 4 made of fiber and the network layer 6 made of metal wire mesh to effectively improve the pressure resistance of the pipe fittings. The elastic pressure-resistant layer 5 and the support layer 4 can not only improve the pressure-bearing performance of the pipe fittings, but also improve the strength of the pipe fittings with the assistance of the network layer 6. When the pipe fittings are under pressure, they will not be completely deformed, so that the pipe fittings have pressure resistance and the normal use of the pipe fittings is guaranteed.

[0027] In this embodiment, the elastic pressure-resistant layer 5 includes an inner layer 501 , an outer surface of the inner layer 501 is fixedly connected to a pressure-resistant column 502 , and one end of the pressure-resistant column 502 is fixedly connected to an outer layer 503 .

[0028] During specific use, the PVC pipe fittings have a certain compression resistance through the arrangement of the compression-resistant column 502 .
