Detailed Description

The present invention is further described in detail below with reference to examples so that those skilled in the art can implement the invention with reference to the description.

It will be understood that terms such as "having," "including," and "comprising," when used herein, do not preclude the presence or addition of one or more other elements or groups thereof.

Example 1

As shown in fig. 1, a heat-shrinkable type coupling for a pipe of a washing machine, comprising: the connecting piece comprises a connecting piece body 1 and a heat-shrinkable tube sleeve 2, wherein the connecting piece body comprises 2 or more than 2 joints, the connecting piece body comprises a straight tube or a bent tube with a valve body, a tee joint, a four-way joint, a five-way joint and the like, and in the embodiment, a T-shaped three-way pipe is selected.

The outer side wall of the connecting piece body is sleeved with a heat-shrinkable pipe sleeve; the heat-shrinkable tube sleeve comprises a linking part 210 wrapped on the outer side of the connecting piece body and tubular connecting parts 220 used for being connected with the tube 4 in the washing machine, the number of the tubular connecting parts is the same as that of the joints (when necessary, the tubular connecting parts are not arranged on part of the joints, and the part of the joints are connected with the tube in other connecting modes), and the tubular connecting parts are respectively sleeved on the outer sides of the joints.

The joint part is fixedly connected with the connecting piece body in a sealing mode, and the tubular connecting part extends out of the end portion of the joint.

When the sealing device is used, the tubular connecting part is wrapped in the heat-shrinkable combination with the pipe through the heat-shrinkable treatment, so that the sealing connection and the fixation are realized.

The joining part and the tubular connecting part are integrally formed, and the diameters of the joining part and the tubular connecting part are the same or different.

The material of the joint part and the material of the tubular connecting part are the same.

The tubular connecting part is a rubber-containing heat shrinkable tube material. The glue-containing heat-shrinkable tube sleeve wraps the connecting part of the connector body joint and the pipe, and has good fixed connection and sealing effects on the connecting pipe and the tee pipe.

The connector body is plastic and the tube is preferably of TPV material.
