Problems solved by technology

There are some problems with this structure, the connection is not firm enough, and it is still prone to water leakage; the most important thing is that there is no self-locking sealing device at the plug-in part. Once the quick-plug falls off or loosens, water seepage is inevitable

Embodiment Construction

[0033]The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention. In the drawings, the water inlet pipe of the washing machine is taken as an example, but those skilled in the art know that it is only for illustration and not for limitation.

[0034] as attached figure 1 to attach Figure 10 shown.

[0035] Such as figure 1 , 2 As shown, a self-locking push-in joint 9 includes: a threaded connection body 8 and an elastic element 7, wherein the threaded connection body 8 is cylindrical, and the inner wall of one end of the threaded connection body 8 is provided with a threaded portion 8-1 , the threaded part includes a first internal thread, which is used for threaded connection with a joint on the fluid inflow side, such as a flu...

Abstract

The invention relates to a self-locking quick-plug connector, a self-locking quick-plug connector assembly and an anti-drop quick-plug connecting device. The self-locking quick-plug connector comprises a threaded connecting body (8) and an elastic element (7), wherein the threaded connecting body (8) is cylindrical; the inner wall of one end of the threaded connecting body (8) comprises a threaded part (8-1); a first internal thread is arranged on the threaded part and used for being in threaded connection with a connector on the inflow side of a fluid; a connecting part is arranged on the inner wall of the part, where the first internal thread is not arranged, of the threaded connecting body (8); the elastic element (7) takes the shape of a cylinder with a closed end and an open end, and is built in the threaded connecting body (8); the open end is in adaptive connection with the connecting part on the inner wall of the threaded connecting body (8); and the closed end faces the threaded part of the threaded connecting body (8). By adoption of the self-locking quick-plug connector disclosed by the invention, automatic self-locking can be ensured as long as the self-locking quick-plug connector is dropped under any unexpected circumstance, thereby cutting off the fluid and avoiding leakage of the fluid.

Description

technical field [0001] The invention relates to the connection field, in particular to a pipeline plug joint, in particular to a self-locking quick plug joint and an anti-dropping quick plug connector, which can be used in a self-locking device for a fluid pipe with a pressure difference on both sides to prevent Fluid leakage and backflow; especially can be used as an anti-running water plug joint for the water supply pipe of the washing machine. Background technique [0002] A quick connector is a connector that can be connected or disconnected without tools. The quick connector is generally composed of a lock joint as a mother body and a plug joint as a daughter body, and the plug joint is inserted into the lock joint. When the plug joint is pulled out, it is very easy to cause fluid leakage and cause a safety accident. [0003] The water injection pipe of the existing washing machine is a plastic hose. When the water pressure increases slightly during use, the joint wil...
