Quick connecting joint cap for water pipe

Abstract

The invention discloses a quick connecting joint cap for a water pipe. The quick connecting joint cap is provided with a joint cap body of which the interior is provided with a cylindrical hollow displacement groove; groove ports communicating with the displacement groove are arranged at the two ends of the connecting portion between the joint cap body and a pipe connecting port a arranged on theupper portion of the joint cap body, and elastic locks are slidably arranged in the groove ports; each elastic lock is overall in an inverted L shape, the hole diameter of each elastic lock is slightly larger than that of the displacement groove formed in the joint cap body, one end of the hole diameter of each elastic lock is aligned with the displacement groove, and the other end of each elasticlock is staggered with the displacement groove and communicates with the pipe connecting port a and the displacement groove; a half circle of a convex platform is arranged at the edge of the upper portion of the end, aligned with the displacement groove, of the hole diameter of each elastic lock, and the edge of the lower portion is still aligned with one end of the displacement groove; a springis fixed between the side pressing portion of each elastic lock and the joint cap body; and a pipe connecting port b which is in threaded connection with the joint cap body is arranged at the bottom of the joint cap body and used for being in threaded connection with other water pipes. According to the quick connecting joint cap for the water pipe, the water pipe can be quickly connected from thetwo ends, operation is easy, connection is firm, and slippage is not prone to occurring.

Description

technical field [0001] The invention relates to a connecting joint device, in particular to a water pipe fast connecting joint cap. Background technique [0002] The connection methods of the existing water pipes are mainly threaded connections or directly snapping the connectors into the water pipes with certain elasticity, but this connection method is either troublesome or the connection is not firm and easy to slip. Especially in some special occasions, such as fire extinguishing, emergency water supply and other occasions, it is very important to be able to connect the water pipes conveniently, quickly and firmly. Contents of the invention [0003] In order to solve the problem of cumbersome water pipe connection and easy slipping, the invention provides a water pipe quick-connect joint cap; the water pipe quick-connect joint cap can not only quickly connect water pipes from both ends, but also is easy to operate, firmly connected, and not easy to slip off.
