Description

Technical Field

[0001] The utility model belongs to the technical field of copper inserts for pipe fittings, in particular to a copper insert for preventing a joint from falling off. Background Art

[0002] Copper inserts are a kind of copper accessories embedded in plastics. They are widely used. The main purpose of copper inserts is to inject products into some plastic parts. After installation, an effective internal thread can be formed on the plastic parts. The operation method is to heat the product and then embed it into the plastic part or directly use mold injection molding. Because brass has good thermal conductivity, pressing the copper insert into the plastic matrix after heating can make the product quickly heat up and speed up work efficiency. The heated copper insert can also quickly transfer heat to the plastic part, so that the periphery of the plastic hole changes, thereby quickly pressing the product into the hole. If mold injection molding is used, after the copper insert is hot-injected into the plastic part, due to the embossing process on the outer diameter of the product, a certain friction and bite force are formed with the product after forming, which can fix it inside and prevent it from falling off. In order to make the water supply pipeline easy to install and the connection reliable, a water pipe joint is usually installed at the connection of the water supply pipeline, and a copper insert is inlaid in the water pipe joint.

[0003] As a connector, the copper insert should have good waterproof performance, but the existing copper inserts still have shortcomings. First, most of the existing PPR pipe copper inserts are connected by clips. After long-term use, the copper inserts are loose due to the effect of water pressure and the impact of water flow, which leads to water leakage. Secondly, some copper inserts with threaded connections are easy to loosen when the connector is rotated and tightened, causing gaps in the copper inserts of the water pipe joints, thereby causing water leakage in the connector, thereby reducing the reliability of the copper inserts.

[0005] The utility model provides the following technical solution: a copper inlay for preventing a joint from falling off, comprising a connecting piece, one end of the connecting piece is fixedly connected to an external threaded tube, one end of the connecting piece is fixedly connected to an embedded tube, a plurality of embedded rings are fixedly connected to the surface of the embedded tube, and the plurality of embedded rings are evenly arranged, a tube body is sleeved on the surface of the embedded tube, a connecting ring is sleeved on the surface of the connecting piece, a plurality of rotating grooves are provided on both sides of the connecting ring, and the plurality of rotating grooves are evenly arranged in a ring shape, a hook block is hinged inside the rotating groove, a hook embedding groove is provided on the surface of the tube body, and the hook embedding groove is clamped with the hook block.

[0006] The beneficial effects of the utility model are as follows:

[0007] 1.
