In addition, the present structure also includes a dust cap 10, the dust cap 10 is used to cover the ends of the male connector 1 and the female connector 2, and when the male connector 1 and the female connector 2 are not in use or are used separately, the insides of the male connector 1 and the female connector 2 are kept clean to prevent dust from entering. Specifically, the dust cap 10 can be covered on the ends of the shell 1 101201 of the male connector 1 and the shell 2 of the female connector 2. The structural form of the dust cap 10 is as follows Figure 7 shown.

[0034] A male connector 1 comprises a housing 101201 and a bushing 102, a spring 103 and a valve core 104 which are sequentially arranged inside the housing 101201; wherein the housing 101201 is sequentially provided with a first channel 107, a second channel 108 and a third channel 109, the diameter of the first channel 107 is larger than the diameters of the second channel 108 and the third channel 109, and the diameter of the second channel 108 is smaller than the diameter of the third channel; the bushing 102 and the spring 103 are both located in the first channel 107 and the bushing 102 is close to the end of the housing 101201, and the bushing 107 is adjacent to the end of the housing 101201. 2 is against one end of the spring 103, and the other end of the spring 103 is against the end face of the valve core 104; the valve core 104 includes a guide section 110 and a sealing section 111, the guide section 110 is located inside the first channel 107 and forms a channel with the first channel 107, the end face of the guide section 110 is against the other end of the spring 103, and the diameter is larger than the diameter of the second channel 108, the diameter of the sealing section 111 close to the guide section 110 is equal to the diameter of the second channel 108, and the diameter away from the guide section 110 is smaller than the diameter of the second channel 108.

[0035] When the male connector 1 is in a natural state, that is, when it is not connected to the female connector 2, the spring 103 is in a compressed state. Under the action of its elastic restoring force, the other end of the spring 103 provides pressure to the guide section 110, so that the end surface of the guide section 110 is against the end surface of the connection between the first channel 107 and the second channel 108. Figure 1 As shown; and because the diameter of the guide section 110 is larger than the diameter of the second channel 108, the first channel 107 can be sealed to achieve the sealing effect of the entire male connector 1. In order to further increase the sealing performance, a connecting section 115 is further provided between the guide section 110 and the sealing section 111, and the diameter of the connecting section 115 is smaller than the diameters of the guide section 110 and the sealing section 111; and a sealing ring 44 is sleeved on the sealing section 111, and the outer wall of the sealing ring 44 abuts against the inner wall of the second channel 108; this structure can effectively prevent the fluid leaking from the end face of the guide section 110 and the first channel 107 from flowing out from the sealing section 111 to the other end of the housing 101201. When assembling, the male connector 1 is assembled from the first channel 107, and the valve core 104, the spring 103 and the bushing 102 are sequentially inserted from the first channel 107.

[0036] An external thread 105 and a support platform 106 are provided on the outer wall of the shell 101201. The external thread 105 is arranged at the end of the shell 101201 corresponding to the bushing 102, and the external thread 105 is used to connect with the pipeline; the support platform 106 is arranged in the middle of the shell 101201.

[0037] The female connector 2 comprises a housing 2 and a bushing 202, a spring 203 and a valve core 204 which are sequentially arranged inside the housing 2; a fourth channel 207 and a fifth channel 208 are sequentially arranged inside the housing 2, and the diameter of the fourth channel 207 is larger than the diameter of the fifth channel 208; the bushing 202 and the spring 203 are both located in the fourth channel 207 and the bushing 202 is close to the end of the housing 2, the end face of the bushing 202 is against one end of the spring 203, and the other end of the spring 203 is against the The end face of the valve core 204 is abutted against each other; the valve core 204 includes a guide section 209 and a sealing section 210, the guide section 209 is located inside the fourth channel 207 and forms a channel with the fourth channel 207, the end face of the guide section 209 is abutted against the other end of the spring 203, and the diameter is greater than the diameter of the fifth channel 208, the diameter of the sealing section 210 close to the guide section 209 is equal to the diameter of the fifth channel 208, and the diameter away from the guide section 209 is smaller than the diameter of the fifth channel 208.

[0038] When the female connector 2 is in a natural state, that is, when it is not connected to the male connector 1, the second spring 203 is in a compressed state. Under the action of its elastic restoring force, the other end of the second spring 203 provides pressure to the second guide section 209, so that the end face of the second guide section 209 abuts against the end face of the connection between the fourth channel 207 and the fifth channel 208. Figure 2As shown; and because the diameter of the second flow guide section 209 is larger than the diameter of the fifth channel 208, the fourth channel 207 can be sealed to achieve the sealing effect of the entire female connector 2. To further increase the sealing performance, a second connecting section 211 is provided between the second flow guide section 209 and the second sealing section 210, and the diameter of the second connecting section 211 is smaller than the diameters of the second flow guide section 209 and the second sealing section 210; and a sealing ring 44 is also sleeved on the second sealing section 210, and the outer wall of the sealing ring 44 abuts against the inner wall of the fifth channel 208; this structure can effectively prevent the fluid leaking at the end surface of the second flow guide section 209 and the fourth channel 207 from flowing out from the second sealing section 210 to the other end of the second housing. In this embodiment, the valve core 104 and the valve core 204 have the same structural shape. The valve core, the flow guide section, the sealing section and the connecting section in the following description all refer to the valve core 104 and the valve core 204, the flow guide section 110 and the flow guide section 209, the sealing section 111 and the sealing section 210, the connecting section 115 and the connecting section 211. The female connector 2 is assembled from the fourth channel 207, and the valve core 104, the spring 103 and the bushing 102 are sequentially inserted from the fourth channel 207.

[0039] An external thread 205 and a limit platform 206 are provided on the outer wall of the second shell. The external thread 205 is arranged at the end of the second shell corresponding to the second bushing 202, and the external thread 205 is used to connect the pipeline; the limit platform 206 is close to the other end of the second shell, and its diameter is equal to the diameter of the third channel 109, and the diameter between the limit platform 206 and the other end of the second shell is equal to the diameter of the second channel 108.

[0040] In order to increase the stability of the connection between the bushing 1 102 and the bushing 2 202 and the male connector 1 and the female connector 2 and to locate their installation positions, the bushing 1 102 and the bushing 2 202 are provided with a boss 7 in the middle of their outer walls; the first channel 107 and the fourth channel 207 are provided with a slot 8 that matches the boss 7 on their inner walls. In order to make the boss 7 in the bushing 1 102 and the bushing 2 202 smoothly match the slot 8 in the first channel 107 and the fourth channel 207, the bushing 1 102 and the bushing 2 202 should have a certain degree of deformation. In this embodiment, the bushing 1 102 and the bushing 2 202 are made of polyurethane.

[0041] Furthermore, both the housing 101201 and the housing 2 are provided with a clamping plate 9; the clamping plate 9 on the housing 101201 is close to the external thread 105, and a sealing ring 216 is provided between the clamping plate 9 and the external thread 105; the clamping plate 9 on the housing 2 is close to the external thread 205, and a sealing ring 312 is provided between the clamping plate 9 and the external thread 205. The sealing ring 216 and the sealing ring 312 are used to fill the gap between the threads and prevent the leakage of fluid and impurities when the male connector 1 and the female connector 2 are connected to the pipeline.

[0042] Reed clip 3, such as Figure 6 As shown, it includes a middle part 301 and connecting parts 302 arranged on both sides of the middle part 301; the middle part 301 is sleeved on the middle part of the outer wall of the female connector 2, the connecting part 302 extends in the direction of the valve core 204 and exceeds the end face of the shell 2, and the end of the connecting part 302 is bent in the direction of the end face of the shell 2 to form a hook 303; the hook 303 is used to abut against the table surface of the abutting platform 106 to connect the male connector 1 and the female connector 2. In order to facilitate the fixing of the clip spring 3 on the female connector 2, in this embodiment, the shell of the shell 2 is also provided with a stepped platform 213 with a diameter larger than the clamping platform 9, and the clamping platform 9 is provided with the clip spring 3 and the gasket 214; the inner end face of the middle part 301 of the clip spring 3 abuts against the end face of the stepped platform 213, and the outer end face abuts against one end of the gasket 214, and the other end of the gasket 214 contacts the sealing ring 3 212. This structure utilizes sealing ring three 212 and gasket 214 to press the spring sheet 3 against the stepped platform 213, so that the spring sheet 3 is fixed on the platform 9; and it is also easy to assemble. During assembly, the spring sheet 3, gasket 214 and sealing ring three 212 are sequentially put on the outer wall of the female connector 2 from one side of the fourth channel 207.

[0043] When the male connector 1 and the female connector 2 are connected, the end faces of the housing 1 101201 and the housing 2 where the external thread 1 105 and the external thread 2 205 are close are separated, and the other end faces are close, and the housing 2 of the female connector 2 is inserted into the third channel 109 until the end faces of the limiting platform 206 and the connection between the second channel 108 and the third channel 109 are abutted. At this time, the end face of the hook 303 on the clip spring 3 just contacts the abutting platform 106, and under the action of the clip spring 3, the male connector 1 and the female connector 2 are fixed. The outer wall of the housing 1 101201 gradually shrinks from the abutting platform 106 to the end away from the bushing 1 102, reducing the resistance of the connection part 302 and the hook 303 to move toward the abutting platform 106. During the insertion process, valve core 204 contacts the end face of valve core 1 104, and under the interaction force, each moves toward the direction close to its bushing, so that the end of guide section 1 110 is away from the end faces at the first channel 107 and the second channel 108, and the end of guide section 209 is away from the end faces at the fourth channel 207 and the fifth channel 208, forming a passage between the second channel 108 and valve core 1 104, and between the fifth channel 208 and valve core 2 204.

[0044] In order to avoid that when the male connector 1 and the female connector 2 are connected, the position of the sealing section 111 away from the guide section 110 does not form a passage with the second channel 108, and the position of the sealing section 210 away from the guide section 209 does not form a passage with the fifth channel 208; in this embodiment, the sealing section 111 and the sealing section 210 are both provided with a plurality of grooves 5 along their circumferences, and the grooves 5 extend from one end of the sealing section away from the guide section to the connecting section but do not penetrate the sealing section, such as Figure 5 When the male connector 1 and the female connector 2 are connected, the valve core moves to the position where the groove 1 5 corresponds to the second channel 108 and the fifth channel 208 to form a passage. In addition, the guide section 1 110 and the guide section 2 209 are both provided with a plurality of grooves 2 6 passing through their end surfaces along their circumferential direction to increase the flow rate during conduction.

[0045] When the shell 2 is inserted into the shell 1 101201, in order to prevent the fluid from leaking from the gap between the third channel 109 and the shell 2, the shell 1 101201 is further provided with a sixth channel 112 and a seventh channel 113. The sixth channel 112 is connected to the third channel 109 and has a diameter larger than the third channel 109. The diameter of the seventh channel 113 is smaller than the diameter of the sixth channel 112 but not smaller than the diameter of the third channel 109. Figure 3 As shown, a sealing ring 114 is provided inside the sixth channel 112. The inner ring of the sealing ring 114 abuts against the outer wall of the second housing, and the second housing and the third channel 109 and the sixth channel 112 are sealed. The novel quick-insertion structure designed by the present invention is used for connecting two pipelines, and the male connector 1 and the female connector 2 can be quickly disassembled and assembled, and has strong sealing and is not easy to leak.
