Description

Technical Field

[0001] This utility model relates to the field of PVC pipe port limiting, and in particular to a PVC pipe port limiting mechanism. Background Technology

[0002] PVC pipe, also known as polyvinyl chloride pipe, is a pipe material made by using polyvinyl chloride resin as the main raw material, adding auxiliary materials such as stabilizers, lubricants, fillers and colorants, and then extruding it.

[0003] In existing technology, when connecting two PVC pipes, the ends of the two PVC pipes are usually aligned and then a limiting mechanism is used to connect and fix the ends of the adjacent PVC pipes. The limiting mechanism usually includes flanges, studs, and nuts. The adjacent flanges are located at the ends of the adjacent PVC pipes, and the studs are connected to the two flanges. The nuts are threaded onto the outside of the studs to lock and fix the adjacent flanges, thereby achieving the connection and fixation of the ends of the adjacent PVC pipes.

[0004] However, the connection between the nut and the stud is usually exposed to the outside, and is therefore affected by the external environment, which can cause the connection between the nut and the stud to rust and become stuck, affecting the disconnection of the two PVC pipe ports. Therefore, it is necessary for the PVC pipe port limiting mechanism to protect the nut. Utility Model Content

Studs 4 are slidably inserted into adjacent flanges 3, which facilitates the insertion of adjacent flanges 3 to connect and fix them. Nuts 6 are inserted through the external threads of the studs 4, which facilitates the connection with the studs 4 to make the two flanges 3 fit tightly and lock and fix them, thereby realizing the connection and fixation of the ports of the first pipe body 1 and the second pipe body 2. The protective mechanism 5 is located on the side of the flange 3 and is used to protect the outside of the nut 6.

[0041] Furthermore, the protection mechanism 5 includes a bearing ring 51, a protective cylinder 52, a connecting assembly, and a positioning element. The bearing ring 51 is semi-circular, and two protective cylinders 52 are semi-cylindrical on one bearing ring 51. The upper and lower protective cylinders 52 can form a complete protective cylinder 52, and sealing gaskets are provided on the sides between the upper and lower protective cylinders 52. Sealing gaskets are also provided on the sides of the remaining protective cylinders 52, which helps to improve the sealing performance of the connection between the protective cylinder 52 and the flange 3, so as to protect the nut 6 and prevent it from rusting. The bearing ring 51 helps to support the protective cylinder 52, and the bearing ring 51 is slidably sleeved. Outside the second tube body 2, the protective sleeve 52 is fixedly connected to the side of the bearing ring 51. The protective sleeve 52 is slidably sleeved on the outside of the nut 6. The inside of the protective sleeve 52 is embedded with a limiting sleeve 510, which helps to limit the position of the nut 6, so as to prevent the nut 6 from slipping and to prevent the nut 6 from loosening. The limiting sleeve 510 is slidably sleeved on the outside of the stud 4. The side of the limiting sleeve 510 is in contact with the nut 6. The connecting assembly is located on the bearing ring 51.
