Description

Technical Field

[0001] This utility model relates to the field of PVC pipes, and in particular to a wear-resistant PVC pipe that is resistant to freezing and cracking. Background Technology

[0002] PVC material itself has good corrosion resistance and can resist the erosion of a variety of chemicals, making it suitable for use in chemical and wastewater treatment fields.

[0003] To improve the antifreeze and wear resistance of PVC pipes, antifreeze additives and wear-resistant materials are usually added to the PVC pipe manufacturing material. In addition, to improve its compressive strength, the thickness of the PVC pipe is also increased. However, this increases the manufacturing cost of PVC pipes. During installation and use, only part of the PVC pipe will be subjected to friction and compression. Increasing the overall thickness of the PVC pipe will increase the manufacturing cost, and as the PVC pipe wears down, its thickness will gradually decrease, thus having certain defects.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Example 1

[0039] This utility model provides, for example Figure 1-2The illustration shows a frost-resistant and crack-resistant PVC pipe, comprising a PVC pipe body 1 and a protective component 3. The PVC pipe body 1 has an externally injection-molded wear-resistant layer 2. During injection molding, antifreeze additives are added to the PVC material to improve the frost resistance of the PVC pipe body 1. The protective component 3 is disposed on the outside of the PVC pipe body 1 and includes a first arc plate 31, a second arc plate 32, a protective gasket 33, and a fixing component 34. The first arc plate 31 and the second arc plate 32 are symmetrically fitted onto the outside of the PVC pipe body 1. The first arc plate 31 and the second arc plate 32 are used to protect the PVC pipe body 1. For wear-resistant and pressure-resistant protection, when installing and using the PVC pipe body 1, a relative number of first arc plates 31 and second arc plates 32 can be installed on the PVC pipe body 1 according to the actual installation and use status of the PVC pipe body 1. Protective gaskets 33 are respectively fixedly connected to the inside of the first arc plates 31 and second arc plates 32. The protective gaskets 33 can not only improve the stability of the first arc plates 31 and second arc plates 32 installed on the outside of the PVC pipe body 1, but also reduce the friction between the first arc plates 31 and second arc plates 32 and the PVC pipe body 1. The fixing component 34 is set on the side of the first arc plates 31 and second arc plates 32.

[0040] In particular, the fixing component 34 includes a first fixing block 341, a second fixing block 342, a connecting plate 343, a connecting groove, a connecting block 344, and a locking block 345. The first fixing block 341 is fixedly connected to the side of the first arc plate 31, the second fixing block 342 is fixedly connected to the side of the second arc plate 31, the connecting plate 343 is fixedly connected to the top of the second fixing block 342, the outer wall of the connecting plate 343 is engaged with the first fixing block 341, the connecting groove is formed at the top of the first fixing block 341, and the inner wall of the connecting groove... The bottom of the plate has a connecting hole that matches the connecting plate 343. The connecting block 344 is located inside the connecting groove. One side of the locking block 345 is fixedly connected to the connecting block 344. The outer wall of the locking block 345 is slidably inserted into the connecting plate 343. The inner wall of the connecting groove has a locking groove corresponding to the locking block 345. Under the constraint of the locking block 345, the connecting plate 343 can maintain a stable snap-fit ​​with the first fixing block 341, thereby ensuring the stability of the installation of the first arc plate 31 and the second arc plate 32.

[0041] Furthermore, the fixing component 34 also includes a limiting block 346 and an elastic element 347. The limiting block 346 is disposed inside the connecting groove, and the side of the limiting block 346 is pressed and fitted against the connecting block 344, such as... Figure 2As shown, the limiting block 346 can squeeze and limit the two connecting blocks 344, thereby ensuring the stability of the locking block 345 when it is snapped together. The elastic element 347 is installed on the side of the limiting block 346. One side of the connecting block 344 is provided with an arc groove that matches the elastic element 347. Under the action of the elastic element 347, the stability of the limiting block 346 snapped between the two connecting blocks 344 can be improved.

[0042] Furthermore, the fixing component 34 also includes a cover 348, a through hole, and a rubber plug 349. The cover 348 is fixedly connected to the top of the limiting block 346 and is sleeved on the top of the inner cavity of the connecting groove. The through hole is opened on the top of the cover 348, and the rubber plug 349 is engaged inside the through hole. By squeezing the rubber plug 349 into the connecting groove and then pulling out the cover 348 and the limiting block 346 through the through hole, the locking block 345 can be removed, and the first arc plate 31 and the second arc plate 32 can be unlocked.

[0043] Example 2

[0044] Unlike Example 1, as Figure 3 As shown, the fixing component 34 includes a fixing seat 3410, a third fixing block 3411, a mounting bolt 3412, and a connecting rod 3413. The fixing seat 3410 is fixedly connected to the outside of the second arc plate 32, and the third fixing block 3411 is connected to the side of the first arc plate 32. The top of both the third fixing block 3411 and the fixing seat 3410 are provided with bolt holes corresponding to the mounting bolts 3412. Thus, when installing the PVC pipe 1, the mounting bolts 3412 are connected to the installed components, which can fix the first arc plate 31 and the second arc plate 32, thereby installing and fixing the PVC pipe 1. This allows the PVC pipe 1 to be suspended, reducing the friction caused by contact between the PVC pipe 1 and the object. The connecting rod 3413 is fixedly connected to the top of the fixing seat 3410, and the top of the third fixing block 3411 is provided with a connecting hole that matches the connecting rod 3413. The connecting rod 3413 can improve the stability of the connection between the fixing seat 3410 and the third fixing block 3411.
