Quick joint structure

The creation system is related to a quick joint structure, in particular, a quick joint structure is provided with a safety lock structure, and the safety lock is arranged to prevent the action member from being disengaged from the first body during operation.

As we have previously known, the conventional quick joint structure, such as Taiwan Patent Application No.: No. 100212565, certificate number: No. M417473, patent name: spool structure of fluid line quick joint, a fluid line quick joint a valve core structure comprising: a rear seat, a rear sliding sleeve, a middle seat and a valve core; the middle seat thread is connected to the inner cavity of the rear seat; the rear sliding sleeve is sleeved in the inner cavity at one end of the middle seat And sealingly cooperate with the rear seat; the valve core is divided into a valve core body and a front sliding sleeve, a sealing gasket is arranged between the valve core body and the front sliding sleeve, and a sealing body is arranged at one end of the valve core body The sleeve is sleeved in the rear sliding sleeve, the front sliding sleeve is disposed in the inner cavity of the other end of the middle seat, the other end of the valve core body is provided with an annular protrusion, and the other end of the valve core body is provided with a blind hole One end of the gasket is provided with an annular groove sealingly engaging with the annular protrusion, wherein the other end of the gasket is provided with a groove for accommodating a pipe joint ferrule, and the sealing ring and the ring of the valve body a conical connecting body having a large end facing the annular projection between the protrusions, An opening is provided in the conical connecting body to be connected to the blind hole.

However, the lack of structure of this patent is based on: When the pipe joint ferrule is inserted into the middle seat and the front sliding sleeve, the quick joint structure is protected from the safety lock to prevent the pipe joint ferrule from being disengaged from the middle seat and the front sliding sleeve during use.

In view of the lack of the above-mentioned conventional quick joint structure, the creator has been engaged in the manufacturing and design experience of related industries for many years, and finally has a product that can solve the drawbacks of the quick joint structure.

The new problem to be solved: the conventional quick connector is unprotected and has a lack of disengagement. The creation is related to a quick connector structure, especially a quick connector structure with a safety lock structure. The action member can be prevented from being disengaged from the first body during operation.

Technical means for solving the problem: The present invention relates to a quick joint structure, which comprises: a first body; a control group is sleeved with the first body, the control group includes a control collar, a first elasticity The component and the at least one bead; the control collar is sleeved on the outer peripheral surface of the first body and rotatable on the first body, and the control collar is axially movable on the first body to a release position And a latching position, the front end of the control collar is convexly provided with at least one abutting portion; a second system is combined with the first body, and at least one groove is disposed at two sides of the rear end surface of the second body. The groove is provided for the abutment of the control collar to be the same number as the abutment.

Compared with the effect of the prior art: the control collar can be freely rotated on the first body, and when the quick joint structure is combined with the active member, the control collar can be rotated to make the positioning point of the control collar Any positioning slot is sleeved so that the control collar is not aligned The groove of the two body, at this time, the control collar can not move axially on the first body, and the control collar is rotated, so that the abutment and the groove are not relatively positive, that is, the safety lock structure of the quick joint The safety lock is arranged to prevent the active member from being disengaged from the first body due to various factors during operation.

In order to enable the members of the Board and those skilled in the art to fully understand the effects of this creation, the structure and composition of the creation are described in conjunction with the drawings and drawings, but the following are only used to explain the implementation of this creation. For example, it is not intended to impose any form of restriction on the creation of this creation. Any modification made in the spirit of this creation should still be covered by this creation.
