[0025] The receiving pipe 1 further comprises a first inclined pipe 12, a first connecting pipe 13, a second inclined pipe 14, a second connecting pipe 15, a third inclined pipe 16 and a third connecting pipe 17 arranged in sequence from the end close to the connecting pipe 10 to the end away from the connecting pipe 10, the first inclined pipe 12 is used to connect the connecting pipe 10 and the first connecting pipe 13, the second inclined pipe 14 is used to connect the first connecting pipe 13 and the second connecting pipe 15, the third inclined pipe 16 is used to connect the second connecting pipe 15 and the third connecting pipe 17, and each inclined pipe is arranged alternately with a connecting pipe to form a wave-shaped flow channel structure, thereby effectively reducing the impact force in the fluid conveying process.

[0026] The diameter of the first connecting pipe 13 is greater than that of the second connecting pipe 15, and the diameter of the second connecting pipe 15 is greater than that of the third connecting pipe 17.

[0027] The outer wall of the sealing ring is in close contact with the inner wall of the first inclined pipe 12 (as shown in Figure 1 and Figure 2 , which ensures that the fluid has good sealing performance when passing through the connection to avoid leakage.

[0028] Please refer to Figures 1-3 , the receiving plug 2 comprises a plug pipe 20, an inclined connecting section 21 and a sealing pipe 22 arranged in sequence from the end close to the receiving pipe 1 to the end away from the receiving pipe 1, the diameter of the sealing pipe 22 is greater than that of the plug pipe 20, the diameter of the plug pipe 20 is at least 2 mm smaller than that of the sealing pipe 22, the outer peripheral surface of the sealing pipe 22 is in close contact with the inner wall of the sealing member 11, and the inclined connecting section 21 is used to connect the plug pipe 20 and the sealing pipe 22 to realize the guidance during plugging.

[0029] The plug port of the plug pipe 20 is inwardly bent to form a bending section 201, the bending section 201 is matched with the third inclined pipe 16, and the bending section 201 facilitates the insertion of the plug pipe 20 into the receiving pipe 1, and when the bending section 201 contacts the third inclined pipe 16, the plug pipe 20 cannot continue to penetrate.

[0030] The plug pipe 20 is intermittently matched with the connecting pipe 10 to facilitate the insertion of the plug pipe 20 into the connecting pipe 10, and the outer peripheral surface of the plug pipe 20 is provided with an anti-disengagement member 3, the anti-disengagement member 3 is arranged at the connection between the plug pipe 20 and the inclined connecting section 21, the anti-disengagement member 3 is a right-angled triangular clamping block 31 arranged in a circular array on the outer peripheral surface of the plug pipe 20 with the axis of the plug pipe 20 as the center, the inclined surface of the right-angled triangular clamping block 31 faces the insertion direction of the plug pipe 20, which facilitates the smooth entry of the right-angled triangular clamping block 31 into the receiving pipe 1, and the material used for the right-angled triangular clamping block 31 is a corrosion-resistant material.

[0031] The top of the right-angled triangular clamping block 31 is higher than the end surface of the sealing pipe 22, and the vertical side surface of the right-angled triangular clamping block 31 abuts against the end of the sealing element 11 when the receiving plug 2 is inserted to the limit position. The top of the right-angled triangular clamping block 31 is provided with a chamfer, which is designed to facilitate the insertion of the right-angled triangular clamping block 31 into the wiring pipe 10 during the insertion process, and also prevents the right-angled triangular clamping block 31 from damaging the sealing element 11.

[0032] Please refer to Figures 1-3 The working principle is as follows: when the receiving plug 2 is inserted into the receiving pipe 1, the bent section 201 of the plug pipe 20 is inserted into the wiring pipe 10, and when the plug pipe 20 is inserted, the inclined surface of the right-angled triangular clamping block 31 contacts the inner wall of the sealing element 11 and causes the sealing element 11 to elastically deform. As the insertion depth increases, the right-angled triangular clamping block 31 gradually passes over the step of the inner wall of the sealing element 11, and when it reaches the preset position, the sealing element 11 returns to its original state, and the end surface thereof tightly abuts against the vertical side surface of the right-angled triangular clamping block 31, thereby achieving axial limiting and anti-disengagement locking. At this time, the sealing pipe 22 is completely abutted against the inner wall of the sealing element 11, thereby forming double sealing and preventing fluid leakage at the connection.

[0033] Embodiment two: please refer to Figure 1 Different from the embodiment one, the anti-disengagement element 3 is replaced by two rectangular elastic plates 32 which are arranged on the outer circumferential surface of the plug pipe 20 in an upper-lower interval, and the opposite ends of the two rectangular elastic plates 32 are connected to the outer circumferential surface of the plug pipe 20, and the facing ends of the two rectangular elastic plates 32 extend outward in the direction of the sealing element 11.

[0034] When the receiving plug 2 is inserted into the receiving pipe 1, the rectangular elastic plates 32 are elastically deformed by being pressed by the inner wall of the sealing element 11, and are radially contracted along the plug pipe 20. When the rectangular elastic plates 32 pass over the inner wall of the sealing element 11, the rectangular elastic plates 32 return to their original state under the elastic action of themselves, and the end portions thereof abut against the end surface of the sealing element 11, thereby forming axial limiting and preventing the plug pipe 20 from being accidentally disengaged. The material of the rectangular elastic plates 32 is a corrosion-resistant material.
