Description

Bent pipe convenient to connect

Technical Field

The utility model belongs to the technical field of hot-water heating tubular product and specifically relates to a return bend convenient to connect.

Background

At present, the common elbow joints in the market are connected by threads and are sealed by the thread seal strips, so that the operation mode is complicated and the working efficiency is low. In addition, a connection mode is adopted, hot melting is adopted, special equipment is needed in the operation mode, the operation mode is not beneficial to the self-connection operation of ordinary families, and certain limitation exists, so that the applicant provides improvement on the basis of the operation mode, designs a bent pipe convenient to connect, and is simple in overall operation and capable of improving the working efficiency.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a return bend convenient to connect, whole easy operation improves work efficiency.

In order to achieve the above purpose, the technical scheme of the utility model is that:

the utility model provides an elbow convenient to connect, includes right angle type body, its characterized in that: the two ends of the pipe body are respectively provided with a quick connector; the pipe body outer wall middle part forms the dull polish layer, body outer wall both ends form the convex layer, and form the ring channel on the convex layer.

It is right the utility model discloses do further preferred, form 2 seal grooves on the body both ends inner wall bottom respectively be equipped with the sealing washer in the seal groove.

It is right the utility model discloses do further preferred, the outside of seal groove is equipped with ring groove, ring groove's bottom forms the annular card limit, the outside limit on annular card limit is the perpendicular, and inboard limit is the inclined plane.

It is right to the utility model discloses do further preferred, the ring groove inner wall with it is protruding to form the annular card between the body inner wall.

It is further preferred that the inner wall of the ring-shaped clamping groove comprises an inclined wall and a vertical wall connected with each other.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model is provided with the quick-plug connectors at the two ends of the tube body respectively; the body outer wall middle part forms the dull polish layer, body outer wall both ends form the convex layer, and form the ring channel on the convex layer, realize easy to assemble to form 2 seal grooves on the inner wall, play fine sealed effect, added electroplating in addition on the basis of product copper, the product is difficult for rustting. The PPR pipe is inserted without hot melting, and can be inserted and taken out, and the clamping sleeve is convenient to pull out by a button.

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.
