[0003] The utility model overcomes the shortcomings of the prior art and provides a pipeline quick-connect joint.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a pipeline quick-connect connector, comprising:

[0005] Valve body;

[0006] A valve core is installed inside the right port of the valve body;

[0007] A tail joint, fixedly connected to the right end of the valve body through threads;

[0008] The invention is characterized in that: an outer valve sleeve is sleeved on the left end of the valve body, a valve sleeve spring and a first sealing ring are arranged between the outer valve sleeve and the valve body, a plurality of steel balls evenly distributed in a circumference are arranged on the outer wall of the left end of the valve body, a circle of annular grooves matching with the steel balls is arranged on the inner wall of the right port of the outer valve sleeve, the left end of the valve body passes through the outer valve sleeve and is fixed by a first retaining spring; an inner valve sleeve is sleeved on the outer wall of the valve core, and two second sealing rings are arranged between the inner valve sleeve and the valve core.

[0009] In the above structure, a valve core spring is provided between the valve core and the valve body.

[0010] In the above structure, a second retaining spring is sleeved on the outer wall of the right end of the inner valve sleeve.

[0011] Compared with the prior art, the utility model has the following beneficial effects: the utility model has a reasonable structural design for the pipeline quick-connect joint, an annular groove is designed on the inner wall of the right port of the outer valve sleeve, the annular groove is adapted to the arc surface of the steel ball part, and when the space occupied by the steel ball remains unchanged, the inner wall of the port of the outer valve sleeve and the outer wall of the valve body will tend to be close, and under the action of the first retaining spring, the probability of foreign matter entering can be greatly reduced, thereby improving the working stability of the joint and extending its service life, with ingenious design, reasonable structure and strong practicality.

[0016] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0017] like Figure 1-2 As shown, a pipeline quick-connect connector includes:

[0018] Valve body 1;

[0019] The valve core 2 is installed inside the right port of the valve body 1;

[0020] The tail connector 3 is fixedly connected to the right end of the valve body 1 through threads;

[0021] The invention is characterized in that: an outer valve sleeve 4 is sleeved on the left end of the valve body 1, a valve sleeve spring 5 and a first sealing ring 6 are arranged between the outer valve sleeve 4 and the valve body 1, a plurality of steel balls 7 evenly distributed in a circumference are arranged on the outer wall of the left end of the valve body 1, a circle of annular grooves 8 matching with the steel balls 7 are arranged on the inner wall of the right port of the outer valve sleeve 4, and the left end of the valve body 1 passes through the outer valve sleeve 4 and is fixed by a first retaining spring 9; an inner valve sleeve 10 is sleeved on the outer wall of the valve core 2, and two second sealing rings 11 are arranged between the inner valve sleeve 10 and the valve core 2.

[0022] In the above structure, a valve core spring 12 is provided between the valve core 2 and the valve body 1 .

[0023] In the above structure, a second retaining spring 13 is sleeved on the outer wall of the right end of the inner valve sleeve 10 .

[0024] The utility model has a reasonable structural design for the pipeline quick-connect joint. An annular groove is designed on the inner wall of the right port of the outer valve sleeve. The annular groove is adapted to the arc surface of the steel ball portion. When the space occupied by the steel ball remains unchanged, the inner wall of the port of the outer valve sleeve and the outer wall of the valve body will tend to be close. In addition, under the action of the first retaining spring, the probability of foreign matter entering can be greatly reduced, thereby improving the working stability of the joint and extending its service life. The utility model has a clever design, a reasonable structure and is extremely practical.

[0025] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
