[0002] Plastic water supply pipes are mostly laid inside roughcast houses. The internal environment of roughcast houses is complex and the air is seriously dusty, which causes a large amount of sewage and dust to adhere to the inner wall of the pipe during the storage and installation of the pipe. Because the dirt is attached to the inner surface of the pipe wall, it is difficult to clean it, especially in the deep part of the pipe cavity. These dirt have complex components and are prone to corrosion of pipe fittings and water pollution after the pipe is passed through the water.

[0003] Water supply pipes are mainly closed by pipe caps. In the past, pipe caps made of nylon or soft PVC were used at the ports of pipe fittings to block the ports of pipe fittings to prevent dirt from entering the pipe cavity. Conventional pipe caps are inconvenient to disassemble and assemble, and have poor structural stability, which often leads to damage to the pipe caps during use. Therefore, a new easy-to-pull pipe cap is urgently needed to solve the above problems. Utility Model Content

[0024] As Figures 1 - 4 shown, an easy-to-pull pipe cap is proposed in an embodiment of the present application, including: an end cap 1, a core body 2, and a pull ring 3. The core body 2 and the pull ring 3 are respectively connected to opposite sides of the end cap 1. The end cap 1 is used to cover the port of the pipe. The core body 2 is used to extend into and be clamped to the inner wall of the port of the pipe. The pull ring 3 includes a plate body 31 and an enclosure 32. The plate body 31 is connected to the end cap 1 and extends in a direction away from the core body 2. The plate body 31 is provided with a hollow hole 33 that penetrates the plate body 31. The enclosure 32 is located at one end of the plate body 31 away from the end cap 1, and the extending direction of the enclosure 32 intersects with the extending direction of the plate body 31.

[0025] Based on the above technical scheme, the easy-to-pull pipe cap of the present application, the end cover 1 is used to cover the port of the pipe, so as to seal the pipe, the core 2 is connected to one side of the end cover 1, can be extended into the pipe and clamped on the inner wall of the port of the pipe, to fix the pipe cap to the port of the pipe, the pull ring 3 is connected to the other side of the end cover 1, which has a plate body 31 with a hollow hole 33, the hollow hole 33 can be used for the user to insert the finger or other tools for pulling into the hole, and pull it out in the opposite direction of the pipe with force, and in the pulling process, in order to improve the reliability of the pull ring 3 and avoid damage to the pull ring 3 during the pulling process, the end of the plate body 31 is also provided with a baffle 32 structure intersecting with the extension direction of the plate body 31, so as to increase the fulcrum point and improve the strength of the plate body 31 on one side of the pulling direction.

[0026] In some embodiments of the present application, Figure 1 , Figure 4 As shown, the end cap 1 includes a cover plate portion 11 and a bending portion 12, wherein the cover plate portion 11 matches the port shape of the pipe, and the bending portion 12 is connected to the edge of the cover plate portion 11 and defines a clamping groove 13 for clamping the end face of the pipe together with the cover plate portion 11. The end cap 1 can be set to a structure similar to a glass bottle cap, and the clamping groove 13 is formed by connecting the flat cover plate portion 11 and the inclined bending portion 12, so that the end face of the pipe abuts against the clamping groove 13. While the cover plate covers the port and closes the opening, the bending portion 12 further blocks the gap between the pipe and the end cap 1, thereby better achieving a sealing effect and preventing pollutants from entering the interior of the pipe.

[0027] In some embodiments of the present application, Figures 1 - 4 As shown, the core 2 includes a connecting plate 21 and a clamping block 22. The connecting plate 21 is connected to one side of the end cover 1 and extends in a direction away from the pull ring 3.

The end of the arc-shaped plate body 31 has no sudden angular structure, which is not easy to scratch the user, and the enclosure 32 is arranged along the arc-shaped end, which further increases the strength of the enclosure 32 part.

[0032] In some embodiments of the present application, Figures 1 - 4 As shown, the end cover 1, the core body 2 and the pull ring 3 are an integrally formed structure. The pipe cap is made by injection molding technology, so that the purpose of integral molding can be achieved simply and conveniently.

[0033] In some embodiments of the present application, Figures 1 - 4 As shown, the end cap 1, the core 2 and the pull ring 3 are all made of polyethylene material. Polyethylene material is easy to obtain and has low cost. At the same time, wear-resistant additives can be added therein to have good wear resistance.
