Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

Referring to fig. 1-2, the present invention provides an adapter tube, which includes an engaging member 1, a retainer ring 2 and a sleeve 3; the retainer ring 2 is sleeved outside the embedded part 1, and the sleeve 3 is sleeved between the embedded part 1 and the retainer ring 2; the embedded part 1 comprises a first connecting end 11 and a second connecting end 12; the retainer ring 2 and the sleeve 3 are sleeved on the second connecting end 12; further comprises an injection-molded part 4 which is injection-molded and joined to the first connection end 11.

Based on the technical characteristics, the embedded part 1 is placed into a mould and is integrally injected with the injection molding part 4, and then the retainer ring 2 is sequentially arranged on the embedded part 1 and the sleeve 3 is inserted. After the accessory installation is accomplished, roughly repairing the flattening with the same material with specification tubular product one end terminal surface, get rid of the impurity dirt of surface water and various adhesions, through dedicated hot melt instrument, hot melt tubular product and crossover sub pipe fitting simultaneously, according to certain time hot melt back, earlier link together tubular product and 4 hot melts of injection molding. The sleeve 3 is pressed into the grooves of the retainer ring 2 and the embedded part 1 by pressing the retainer ring 2 into the second connecting end 12, so that the pipe 2 is connected into a whole, the connected sleeve 3 is inserted into the metal sleeve 3, and the metal sleeve 3 is pressed and deformed by a pressing tool to form interference fit with the pipe 2, so that connection of different pipes is realized; wherein the injection molding piece 4 can realize the injection molding of different shapes according to the requirements of different pipes.

The sealing ring 5 is sleeved outside the second connecting end 12; the sealing effect is improved by the sealing ring 5.
