Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Embodiment 1: Figure 1-3As shown, the utility model provides an automobile air-conditioning pipeline joint connection structure.

[0020] The invention comprises an air inlet pipe 1, one end of which is fixedly provided with a female end 2, one end of which is provided with a male end 3, one end of which is fixedly provided with an air outlet pipe 4, one end of which is fixedly connected with a flow cut-off device 5, the female end 2 comprises a screw sleeve 20, the inner surface of which is provided with a first thread groove 21, the inner wall of which is sleeved with a mother flow pipe 22, the outer surface of which is fixedly provided with an annular slide rail 220, the inner wall of which is sleeved with a starter flow pipe 26, the inner surface of which is fixedly connected with a first fixing ring 27, one end of which is fixedly connected with a first spring 24, one end of which is fixedly provided with a first spring 24. A cut-off bead 23, the male end 3 includes a male flow pipe 30, the outer surface of the male flow pipe 30 is provided with a first thread 301 used in conjunction with the first thread groove 21, one end of the male flow pipe 30 is threadedly sleeved with a final flow pipe 34, the inner surface of the final flow pipe 34 is fixedly provided with a second fixing ring 340, one end of the second fixing ring 340 is fixedly connected with a second spring 33, one end of the second spring 33 is movably provided with a second cut-off bead 32, one end of the second cut-off bead 32 is fixedly provided with a push pipe 31, the outer surface of the push pipe 31 is provided with a flow groove 310, and the outer surface of the push pipe 31 is fixedly sleeved with a spacer 311. When the gas in the intake pipe 1 enters the female flow pipe 22, the male end One end of the screw sleeve 20 is connected to the first thread groove 21. The rotating screw sleeve 20 moves the male flow pipe 30 toward the female flow pipe 22 through the cooperation of the first thread groove 21 and the first thread 301. The annular slide rail 220 plays a role in fixing the screw sleeve 20 and facilitating the rotation of the screw sleeve 20 on the outer surface of the female flow pipe 22. When the flow groove 310 in the male flow pipe 30 is inserted into the inner diameter of one end of the female flow pipe 22 and contacts the first intercepting bead 23, the first spring 24 at one end of the first intercepting bead 23 applies a reaction force to the first intercepting bead 23, and the second spring 33 at one end of the second intercepting bead 32 applies a reaction force to the second intercepting bead 32, and the male flow pipe 30 rotates. When it reaches a certain extent, the first intercepting bead 23 and the second intercepting bead 32 move horizontally in opposite directions, and the two are separated from the blocked channel. At this time, the circulating gas flows from the flow groove 310 in the push tube 31 to the common flow tube 30 through the channel opened by the first intercepting bead 23, and the circulating gas flows out from the inner groove of the final flow tube 34 to the outlet pipe 4 through the second spring 33. The common flow tube 30 is rotated in the opposite direction to separate from the screw sleeve 20, so that the first intercepting bead 23 and the second intercepting bead 32 at both ends of the push tube 31 are no longer subjected to force, and the first intercepting bead 23 and the second intercepting bead 32 return to their original positions, so that the gas no longer circulates, thereby achieving the purpose of rapid connection.

[0021] The inner wall of the screw sleeve 20 is provided with a sliding groove for cooperating with the annular slide rail 220, and the inner surface of the screw sleeve 20 is slidingly connected to the outer surface of the mother flow pipe 22. The setting of the annular slide rail 220 facilitates the screw sleeve 20 to be fixed on the outer surface of the mother flow pipe 22, and the screw sleeve 20 can rotate along the surface of the mother flow pipe 22.

[0022] The length of the male end 3 is greater than that of the female end 2 . The male end 3 is used in conjunction with the female end 2 , so that one end of the male end 3 can be conveniently inserted into the interior of the female end 2 by rotating the screw sleeve 20 .

[0023] The diameter of the first intercepting bead 23 is larger than the inner diameter of one end of the mother flow tube 22, and the diameter of the second intercepting bead 32 is larger than the inner diameter of one end of the public flow tube 30. The purpose is to make the first intercepting bead 23 and the second intercepting bead 32 block the inner diameter of one end of the mother flow tube 22 and the public flow tube 30 through the ejection of the first spring 24 and the second spring 33, thereby achieving the intercepting effect.

[0024] The first fixing ring 27 , the first intercepting bead 23 , the push tube 31 , the second intercepting bead 32 , and the second spring 33 are all on the same horizontal line, which facilitates the gas to pass through the horizontal flow path.

[0025] A sealing ring is sleeved on the outer surface of the screw sleeve 20 close to the public flow pipe 30, which plays a role in strengthening the sealing between the female end 2 and the male end 3.

[0026] Embodiment 2: Figure 3 As shown, the shut-off device 5 includes a valve body 51, an inner wall of the valve body 51 is provided with a valve groove 510 for cooperating with the valve core 56, a through groove 511 is provided at one end of the valve body 51, a valve cover 52 is fixedly provided at one end of the valve body 51, a second thread groove 53 for cooperating with the threaded rod 55 is provided at one end of the valve cover 52, a handle 54 is rotatably provided at one end of the second thread groove 53, a threaded rod 55 is fixedly connected to one end of the handle 54, and a valve core 56 is fixedly provided at one end of the threaded rod 55. If it is necessary to adjust the flow rate of the circulating gas, the handle 54 in the shut-off device 5 is rotated so that the threaded rod 55 passes through the second thread groove 53 so that the valve core 56 moves horizontally from the valve body 51 to the through groove 511, so that the valve core 56 leaves space for gas circulation, thereby achieving the purpose of controlling the flow rate. When it is necessary to seal the gas, the handle 54 is rotated in the opposite direction so that the threaded rod 55 drives the valve core 56 to move along the valve groove 510 until the valve core 56 closes the flow diameter within the valve body 51, thereby achieving the purpose of sealing the gas circulation.

[0027] The diameter of the valve core 56 is the same as the length of the through groove 511 , and the valve core 56 is used in conjunction with the valve groove 510 , so that the valve core 56 can be driven to move along the through groove 511 by rotating the threaded rod 55 , so that the airflow passes through the flow path of the valve body 51 .

[0028] Working principle: When the gas in the intake pipe 1 enters the main flow pipe 22, the end of the male end 3 close to the screw sleeve 20 is connected to the first thread groove 21, and the screw sleeve 20 is rotated to move the male flow pipe 30 toward the main flow pipe 22 through the cooperation of the first thread groove 21 and the first thread 301. The annular slide rail 220 plays a role in fixing the screw sleeve 20 and facilitating the rotation of the screw sleeve 20 on the outer surface of the main flow pipe 22;

[0029] When the flow groove 310 in the common flow pipe 30 is inserted into the inner diameter of one end of the mother flow pipe 22 and contacts the first intercepting bead 23, the first spring 24 at one end of the first intercepting bead 23 applies a reaction force to the first intercepting bead 23, and the second spring 33 at one end of the second intercepting bead 32 applies a reaction force to the second intercepting bead 32. When the common flow pipe 30 rotates to a certain extent, the first intercepting bead 23 and the second intercepting bead 32 move horizontally in opposite directions, and the two are separated from the blocked channel. At this time, the circulating gas passes through the first The channel opened by the intercepting bead 23 flows from the flow groove 310 in the push tube 31 to the common flow tube 30, and the circulating gas flows out from the inner groove of the final flow tube 34 to the outlet pipe 4 through the second spring 33. The common flow tube 30 is rotated in the opposite direction so that the common flow tube 30 is separated from the screw sleeve 20, so that the first intercepting bead 23 and the second intercepting bead 32 at both ends of the push tube 31 are no longer subjected to force, and the first intercepting bead 23 and the second intercepting bead 32 return to their original positions, so that the gas no longer circulates, thereby achieving the purpose of rapid connection;

[0030] Secondly, if the flow rate of the circulating gas needs to be adjusted, the handle 54 in the intercepting device 5 is rotated so that the threaded rod 55 passes through the second threaded groove 53, so that the valve core 56 moves horizontally from the valve body 51 to the through groove 511, so that the valve core 56 leaves space for gas circulation, thereby achieving the purpose of controlling the flow rate;

[0031] When the gas needs to be sealed, the handle 54 is rotated in the opposite direction so that the threaded rod 55 drives the valve core 56 to move along the valve groove 510 until the valve core 56 closes the flow diameter within the valve body 51, thereby achieving the purpose of sealing the flow of gas.

[0032] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
