Abstract

The invention relates to a self-locking anti-loosening quick connector device. The self-locking anti-loosening quick connector device comprises a male connector body and a female connector body. One end of the male connector body is connected with one end of the female connector body through threads. The self-locking anti-loosening quick connector device is characterized in that the end, connected with the male connector body, of the female connector body is sleeved with a sleeve, a step is arranged in an inner hole of the sleeve, and a step surface is arranged on the outer circumferential surface of the female connector body and sleeved with a spring; one end of the spring abuts against the step in the inner hole of the sleeve, and the other end of the spring abuts against the bottom face of the step surface; first outer teeth are arranged on the outer circumferential surface of the male connector body, and first inner teeth are arranged at one end of the inner hole of the sleeve and engaged with the first outer teeth; second outer teeth are arranged on the outer circumferential surface of the female connector body, and second inner teeth are arranged on the inner surface of the step in the inner hole of the sleeve and engaged with the second outer teeth; the end, connected with the male connector body, of the female connector body is provided with a clamp spring groove, and a clamp spring is arranged in the clamp spring groove. While the fastening effect is guaranteed, the connecting time of the connector is shortened, and the connector is prevented from getting loosened accidentally.

Description

technical field [0001] The invention relates to a self-locking anti-loosening fast joint device, which belongs to the technical field of quick joints. Background technique [0002] At present, the more common joints include threaded joints and ball lock joints. [0003] The main defects of the threaded union are: (1) In order to connect more tightly, there are more threads, and it takes more time to tighten the thread; (2) In order to ensure the fastening effect, it is necessary to use a wrench to tighten; (3) No locking design , easy to loosen. [0004] The main disadvantage of the ball lock joint is that the joint is easy to loosen when the sleeve is accidentally removed. Contents of the invention [0005] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a self-locking anti-loosening quick joint device, which can reduce the time-consuming joint connection while ensuring the fastening effect and prevent accidental looseni...
