[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The utility model provides Figure 1 - Figure 5 The quick-release pipe connector shown in the figure includes a first pipe 1 and a second pipe 2. The ends of the first pipe 1 and the second pipe 2 are both provided with connecting caps 11 through threaded connection. The initial positions of the two connecting caps 11 are located at the threads on the corresponding first pipe 1 and the second pipe 2. The threads are located at the ends of the first pipe 1 and the second pipe 2 close to each other. The external threads on the first pipe 1 and the second pipe 2 are not shown in the figure. This is the prior art and will not be described in detail here. The connecting caps 11 are conventional nuts. This is the prior art and will not be described in detail here. A plurality of arc grooves 7 are opened through the left and right ends of the connecting caps 11. An inner support shell 3 is provided between the first pipe 1 and the second pipe 2, a connecting ring 4 is fixedly provided on the outer side of the inner support shell 3, the connecting ring 4 is located between the two connecting caps 11, a plurality of rectangular grooves 6 are provided through the left and right ends of the connecting ring 4, and the plurality of rectangular grooves 6 are arranged in a ring array, a center rod 8 is movably provided on the inner side of the rectangular groove 6, the outer side of the inner support shell 3 abuts against the inner walls of the first pipe 1 and the second pipe 2, a plurality of sealing plates 5 are movably provided on the outer sides of the first pipe 1 and the second pipe 2, a connecting block 10 is fixedly provided on the outer side of the center rod 8, the connecting block 10 is fixedly connected to the outer side of the sealing plate 5, and the first pipe 1 and the second pipe 2 are located between the sealing plate 5 and the inner support shell 3;

[0025] The operator aligns the first pipe 1 and the second pipe 2, places the inner support shell 3 on the inner wall between the first pipe 1 and the second pipe 2, so that the outer side of the inner support shell 3 contacts the inner wall of the first pipe 1 and the second pipe 2, and completes the preliminary connection of the first pipe 1 and the second pipe 2. When connecting the first pipe 1 and the second pipe 2, align the center rod 8 with the arc groove 7 on the connecting cap 11, and screw the two connecting caps 11 at the same time. The connecting cap 11 drives the center rod 8 to move within a certain range through the arc groove 7. Due to the limitation of the rectangular groove 6, when the center rod 8 moves within a certain range in the arc groove 7, the center rod 8 will move up and down in the rectangular groove 6 at the same time. When the center rod 8 moves to a position close to the 3-axis, the center rod 8 drives the connecting block 10 to move, and the connecting block 10 drives the sealing ring 5 to move, so that the sealing ring 5 is pressed against the surface of the first pipe 1 and the second pipe 2 to achieve positioning and complete the quick connection between the two pipes.

[0026] By setting the arcuate groove 7, the center rod 8 and the rectangular groove 6, whether installing the first pipe 1 and the second pipe 2 or separating the first pipe 1 and the second pipe 2, the pipes can be quickly assembled and disassembled, changing the original need to rotate multiple circles for assembly and disassembly. The number of rotations during assembly and disassembly is greatly reduced, which facilitates the use and arrangement of the pipes. The connecting cap 11 is positioned after rotation, which is convenient and practical.

[0027] The sealing plate 5 is arranged in an arc shape, which is convenient for contacting the outside of the first pipe 1 and the second pipe 2. The inner side of the sealing plate 5 contacts the corresponding outsides of the first pipe 1 and the second pipe 2. The center rod 8 moves through the arc groove 7 to ensure that the arc groove 7 can drive the center rod 8 to move. Two limiting plates 9 are fixed on the outside of the center rod 8. One side of the limiting plate 9 contacts the other side of the connecting ring 4, and the connection is then made through the setting of the limiting plate 9.

[0028] By setting the inner support shell 3 and the sealing plate 5, when the sealing plate 5 presses the first pipe 1 and the second pipe 2, the inner support shell 3 supports the first pipe 1 and the second pipe 2 from the inside to the outside, so as to fix the inner and outer sides of the first pipe 1 and the second pipe 2 in two directions, thereby ensuring the sealing and strength of the first pipe 1 and the second pipe 2 when in use.

[0029] When the first pipe 1 and the second pipe 2 need to be removed, it is only necessary to rotate the two connecting caps 11 so that the connecting cap 11 drives the center rod 8 to move through the arc groove 7. The center rod 8 is limited by the rectangular groove 6 so that it can only move back and forth in one direction. The center rod 8 drives the sealing plate 5 to move, so that the sealing plate 5 moves away from the first pipe 1 and the second pipe 2, completing the separation of the first pipe 1 and the second pipe 2. The separation speed is relatively fast, and only the connecting cap 11 needs to be rotated.
