Problems solved by technology

The disadvantage is that not only the process is complicated, but also the connection strength and sealing are not ideal
Especially the outer diameter of the telescopic hose is too small, even if more glue is applied to seal it, the joints at the end of the hose are still prone to air leakage
In addition, the original telescopic hose with a collar still has the disadvantage of lack of a positioning structure in the combination of the collar and the joint, so the stability after the butt joint is not ideal, and it is necessary to improve

Embodiment 1

[0016] The rubberized collar assembly of this embodiment is as figure 1 , 2 , 3, including the corrugated hose main body 2 made by spirally winding the PVC base strip lined with steel wire according to the conventional process. Rubber joint 4. The two rubber-coated joints 1 and 4 are all through the injection molding process, and the inner ends are respectively coated on the ends of the corresponding telescopic hose main body 2, and form a radial concave-convex fitting structure with the corrugated hose main body 2, and are connected with it as a whole. During actual production, the spirally wound base strips at both ends of the corrugated hose main body 2 are stretched so that adjacent base strips form gaps with each other. In the rubberized joint 1 or 4, a radial concave-convex fitting structure firmly integrated is formed. The outer ends of the two rubber joints 1 and 4 respectively form extended bell mouths, thereby becoming a bell mouth-shaped circumferential sealing s...

Abstract

The invention relates to a rubber-coated rand assembly and belongs to the technical field of fluid delivery lines. The assembly comprises a corrugated hose main body formed by winding a base strip in a spiral way, and at least one end of the corrugated hose main body is provided with a rubber-coated joint; the inner end of the rubber-coated joint is coated at the end of the corrugated hose main body and is connected with the end of the corrugated hose main body into a whole, and the outer end of the rubber-coated joint forms a circumferential sealing structure. As a combined structure reliable in connection is formed among the soft rubber-coated joint, a hard rand and the corrugated hose main body, the rubber-coated rand assembly has the remarkable advantages of freeness in assembling and disassembling, sealing function of the outer end face, zero air leakage, reliability in abutting and positioning, and the like.

Description

technical field [0001] The invention relates to a collar assembly of a telescopic hose, in particular to a rubber-coated collar assembly, which belongs to the technical field of fluid delivery pipelines. Background technique [0002] The telescopic hose with joints and collars includes a corrugated hose body that is helically wound on the base strip and soft joints at both ends. The main body is covered with a hard collar so that after the hose joint is docked with the external port, it can be With the help of the buckle structure on the collar, the reliable connection with the butt end is maintained and slipping is prevented. For a long time, the main body of the telescopic hose with the collar and the joints at both ends have been manufactured separately. After the joint is formed separately, it is screwed to the end of the main body of the hose by hand, and then glued and sealed with the help of glue. When the external port is docked, it needs to be sealed by means of a ...
