Description

Quick female connector

This creation belongs to the field of quick connectors, especially a quick female connector that avoids knotting of the pipe due to rotation.

According to the general pneumatic tools, after connecting with the air pipeline, the air pressure is used as the driving power, and in order to make it easier to use the pneumatic tools, the common way is to extend the pipeline of the gas transportation, so that the user can use the tool. The range can be expanded, so there are a variety of quick connectors for connection in the market, and the so-called quick connector includes a male connector and a female connector, and the male and female connectors are combined with the air pipe ends of the two sides to be assembled. .

However, today's quick joints are screwed together by the connecting pipe and the female joint system, so that when the user adjusts the angle or direction of use of the tool, the pipeline for conveying the gas will be deformed with the rotation or even knotted, so that Gas is difficult to transport to the tool, which in turn reduces work efficiency.

In view of this, the creator feels that he has tried his best to study it, and based on his accumulated experience in the research for many years, he provides a quick female connector, in order to improve the lack of the above-mentioned conventional technology.

One of the purposes of this creation is to provide a quick female connector that allows the user to change the angle or direction of use of the tool so that the gas delivery line does not rotate with it, avoiding knotting of the pipe.

In order to achieve the above object, the present invention discloses a quick female connector, which comprises: a connecting pipe, one end of which is connected to connect a gas conveying pipe, and the other end is provided with a connecting portion, and the connecting portion is provided with a connecting portion a first annular groove; a through pipe having one end connected to the connecting portion, and when connected to each other, the connecting portion extends into the connecting pipe, and the other end of the connecting pipe is provided with a thread, and the connecting pipe is provided with a thread Corresponding to the first annular groove, an opening is provided, and a second annular groove is formed in the inner surface of the through pipe corresponding to the opening, so that the second annular groove communicates with the opening, and When the connecting tube is connected to the connecting portion, a plurality of balls enter the connecting tube from the opening, so that the balls move in a space formed by the first annular groove and the second annular groove, and the The height of the first annular groove and the second annular groove are smaller than the diameter of the balls, so that the balls are located in the space formed by the first annular groove and the second annular groove, the connection The tube is inseparable from the tube and the tube can be rotated relative to the tube; a closure member is disposed in the opening for closing the opening after the ball enters the tube; A female joint pipe body is screwed to one end of the pipe and the other end is coupled to the male joint.

Preferably, the present invention further comprises a gasket, and the connecting portion further comprises a third annular groove, wherein the gasket is disposed in the third annular groove to improve airtightness.

Preferably, the inner bottom surface of the first annular groove is arcuate so that the ball can move more easily.

In some embodiments, a resilient member is interposed between the conduit and the female tubular body, and in some embodiments, the resilient member is further disposed on a ladder to provide a different Connection method.

In this way, through the arrangement of the balls and the space formed by the first annular groove and the second annular groove, when the user adjusts the direction or angle of use of the pneumatic tool, the pipe can be connected with respect to the connection. The tube rotates in accordance with the angle or direction in which the user moves, and avoids the occurrence of knots and the like caused by the rotation of the pipe.

In order for your review board to have a clear understanding of the content of this creation, please use the following instructions to match the drawings.

Please refer to FIG. 1 to FIG. 3 , which are schematic views of an exploded view, a combined schematic view and a joint of the first embodiment of the present invention. As shown, the present disclosure discloses a quick female connector 1 comprising: a connecting tube 11, a through tube 12, a plurality of balls 13, a closure member 14, and a female connector body 15.

One end of the connecting pipe 11 is connected to connect a gas conveying pipe 3, and the other end is provided with a connecting portion 111, and the connecting portion 111 is provided with a first annular groove 112. One end of the through pipe 12 is connected to the connecting portion 111, and when connected to each other, the connecting portion 111 extends into the connecting pipe 12, and the other end of the connecting pipe 12 is provided with a thread, and the connecting pipe 12 is correspondingly The first annular groove 112 is provided with an opening 121, and a second annular groove 122 is defined in the inner surface of the through pipe 12 corresponding to the opening 121, so that the second annular groove 122 and the opening 121 When the connecting tube 111 is connected to the connecting portion 111, the balls 13 enter the connecting tube 12 from the opening 121, so that the balls 13 are in the first annular groove 112 and The space formed by the second annular groove 122 is moved, and the heights of the first annular groove 112 and the second annular groove 122 are smaller than the diameter of the balls 13, so that the balls 13 are located at the first ring. When the groove 112 and the space formed by the second annular groove 122 are formed, the connecting pipe 11 cannot be separated from the through pipe 12, and the through pipe 12 can be rotated relative to the connecting pipe 11. The closing member 14 is disposed on the opening 121 for the balls 13 to enter the through tube 12 The opening 121 is closed, and one end of the female connector body 15 is screwed to the through tube 12, and the other end is connected to the male connector 2.

Through the above structure, when the balls 13 are located in the space formed by the first annular groove 112 and the second annular groove 122, due to the first annular groove 112 and the second annular groove 122 The height of the balls 13 is smaller than the diameter of the balls 13, so that the balls 13 are caught between the first annular groove 112 and the second annular groove 122, so that the through pipe 12 cannot be separated from the connecting pipe 11. At the same time, since the ball 13 is spherical, when the male connector 2 and the quick female connector 1 are connected to each other, the through pipe 12 can be rotated relative to the connecting pipe 11, so that the gas delivery pipe 3 and the tool are formed although mutual The connection is in turn independent of each other in rotation, thereby preventing the gas delivery tube 3 from being knotted by rotation.

In this embodiment, the present invention further includes a gasket 16 , and the connecting portion 111 further includes a third annular groove 113 , so that the gasket 16 is disposed in the third annular groove 113 , so that the pipe is disposed. When the connecting pipe 11 is connected to each other, the gas does not leak from the joint between the two, thereby improving the airtightness. Moreover, the inner bottom surface of the first annular groove 112 is designed to have a circular arc shape, so that the balls 13 can be more easily rolled, thereby improving the rotational freedom of the through tube 12. In addition, only one elastic member 17 is interposed between the through pipe 12 and the female connector body 15 to provide a combination of one of them.

Please refer to FIG. 4, which is an exploded view of the second embodiment of the present creation. As shown in the figure, in the present embodiment, the elastic member 17 can be further disposed on a stepped tube 18 to provide another combination.

In summary, through the arrangement of the balls and the through tube, the through tube 12 can be rotated relative to the connecting tube 11, thereby allowing the gas delivery tube 3 to avoid changing the angle or direction by the tool. Rotation causes knotting and the like to occur.

However, the above descriptions are only for the preferred embodiment of the present invention and are not intended to limit the scope of the present invention; therefore, the equivalent changes and modifications made without departing from the spirit and scope of the present invention should be Within the scope of this creation's patent.
