Detailed Description

The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope defined in the present application.

The utility model relates to a convenient connection structure of a water heating pipe, which comprises an inner pipe 1, wherein the inner pipe 1 is inserted into the water heating pipe to be connected and clamps the wall of the water heating pipe to be connected with an outer pipe 3 together to play a connection role, the outer diameter of the inner pipe 1 is symmetrically provided with a groove, a sealing strip 2 is arranged in the groove, the sealing strip 2 can prevent the leakage of the pipe joint, the two ends of the inner pipe 1 are respectively fixed with the outer pipe 3, the outer pipe 3 is a plastic product or an aluminum product, the axle center of the outer pipe 3 is provided with a first stepped hole, the end with smaller diameter of the first stepped hole is fixedly connected with the inner pipe 1, the matching part of the inner pipe 1 and the outer pipe 3 is provided with screw threads, the screw threads are connected, the difference value between the diameter of the end with larger diameter of the first stepped hole and the outer diameter of the inner pipe 1 is equal to the, sliding connection has clamping ring 4 on outer tube 3, the hole tapering of clamping ring 4 is the same with the tapering of outer tube 3, removes clamping ring 4 and can extrude outer tube 3 to the both ends of inner tube 1, presss from both sides the wall of pressing from both sides tightly waiting to connect the hot-water heating pipeline under the combined action of inner tube 1 and outer tube 3 to play the connection.

In order to prevent that clamping ring 4 from taking place to slide from outer tube 3 in the use, be equipped with the second shoulder hole on clamping ring 4, the second shoulder hole is close to the great one end of 4 internal diameters of clamping ring, install spring 5 and bumping post 6 respectively in the second shoulder hole, spring 5 and bumping post 6 fixed connection, be fixed with spring fender ring 7 on clamping ring 4, spring fender ring 7 and spring 5 contact, bumping post 6 is at the downthehole sliding connection of second shoulder hole, because outer tube 3 external diameter has certain tapering, at the in-process that removes clamping ring 4, bumping post 6 is at the downthehole rebound of second shoulder hole, extrudees spring 5, after the major diameter of outer tube 3 is crossed in the second shoulder hole on clamping ring 4, under spring 5's effect, bumping post 6 stretches out, and it can effectually prevent that clamping ring 4 from taking place the dislocation, can guarantee the compactness at connection position.

In order to connect the hot-water heating pipeline of different diameters, the diameter variation in size at 1 both ends of inner tube, fix the diameter also inequality of two outer tubes 3 and clamping ring 4 on 1 external diameter of inner tube this moment, according to hot-water heating pipeline's specification, can produce different connection structure to swift realization adjacent hot-water heating pipeline's connection.
