Description

Universal air pressure connector with air pressure unlocking function

The present invention relates to a pneumatic connector, and more particularly to an innovative structural type revealer of a universal pneumatic connector having a pneumatic unlocking function.

According to the pneumatic tool, it is a very common tool in the general screw lock operation. Because it requires high-pressure air to act, it must be connected to a pneumatic line. The traditional pneumatic tools and pneumatic pipelines are usually connected by male and female joints. Although the male and female joints have a uniaxial rotation relationship, the male and female joints also change under the action of the high pressure gas. It is not easy to rotate relative to each other, so that when the pneumatic tool has to change the angular position in use, especially when the horizontal angle is changed to the working angle of the elevation angle or the depression angle, the pneumatic pipeline is prone to tortuous torsion, except for the normal gas supply. It will also cause the problem that the pneumatic tools are not easy to operate, so there are related manufacturers to develop various types of universal joints, and hope to solve the above problems.

The existing universal joints between pneumatic tools and pneumatic lines can be roughly divided into two-piece and three-piece types, which are described as follows: Firstly, for a two-piece universal joint, usually It is a ball and socket joint. Although the movable member can swing in a conical three-dimensional space, due to the congenital limitation of the ball and socket member, the angle of the apex angle of the conical space is relatively limited, so it is inevitable that it will be hindered in use. Do not A smooth problem. In the case of a three-piece universal joint, it mainly uses a mutually perpendicular two-axis column to provide a universal rotation function, but the two shaft columns providing the rotation axis are assembled through their adjacent members. Therefore, under the basic requirements of maintaining airtightness, it is necessary to make another effort in the design of the airtight member, which is undoubtedly a difficult problem to be solved for the manufacturing cost. Furthermore, the air passage of such a universal joint must be placed in the shaft column. Unless the volume of the universal joint is increased, the diameter of the air passage will be severely compressed, and the gas flow per unit time will be reduced, which is relatively reduced by the pneumatic tool. Work torque.

The main object of the present invention is to provide a universal air pressure connector, and the technical problem to be solved is to innovate a breakthrough in how to develop a new type of structure with a pneumatic unlocking function that is more ideal and practical. .
