[0041] As mentioned above, in order to improve the assembly efficiency of the connecting pipe, the connecting pipe is generally made of flexible material. Since the working environment of the connecting pipe connected to the power component is relatively harsh, the connecting pipe connected to the power component is prone to aging after long-term use. When maintenance personnel replace the aged connecting pipe, in order to reduce the waste of gas source, the maintenance personnel need to close the solenoid valve first and then replace the aged connecting pipe, which is inconvenient for the maintenance personnel to replace the connecting pipe.

[0042] Reference Figure 1 、 Figure 3 According to the first embodiment of the present invention, the joint with a sealing function is configured as a straight-through joint. The straight-through joint has a cylindrical structure as a whole. The joint with a sealing function includes a joint body 100, a first sealing member 200 and a first valve core 300.

One end of the tube 810 is inserted into the air inlet channel 110 through the first opening, and the other end of the first connecting tube 810 is connected to the output end of the air compressor. When assembling the second connecting tube 820, one end of the second connecting tube 820 is inserted into the air outlet channel 120 through the second opening, and the end of one end of the second connecting tube 820 pushes the first valve core 300 to move in a direction away from the first seal 200 to separate the valve core from the first seal 200. The first valve core 300 is in an open state, and the other end of the second connecting tube 820 is connected to the input end of the power component of the automation equipment. The assembler can add the second connecting tube 820 through a joint with a sealing function, so that the overall length of the first connecting tube 810 and the second connecting tube 820 is increased.

[0043] ReferenceFigure 2 After long time use, the second connecting pipe 820 is easy to be aged, the maintenance personnel pulls out the second connecting pipe 820 from the gas outlet passage 120, because the gas pressure in the gas inlet passage 110 is greater than the air pressure outside, the gas pressure in the gas inlet passage 110 pushes the first valve core 300 to move along the direction close to the first sealing piece 200, so that the first valve core 300 is close to the periphery of the first avoiding hole 210, the first valve core 300 is switched from the opening state to the closed state, the gas in the gas outlet passage 120 cannot continue to be discharged, which can reduce the waste of gas source, the maintenance personnel does not need to close the electromagnetic valve on the first connecting pipe 810, can simplify the maintenance operation of the maintenance personnel, and can facilitate the maintenance personnel to replace the second connecting pipe 820.

[0044] It should be noted that the fluid flowing in the joint with sealing function can be liquid or gas, which is not limited here.

[0045] Referring to Figures 4 to 6 In some embodiments of the utility model, positioning structure is established between first valve core 300 and joint main body 100, and positioning structure is used for coaxially arranging first valve core 300 with gas outlet passage 120, can avoid the situation that first valve core 300 and first sealing piece 200 are misaligned to cause the sealing failure of joint with sealing function, and can improve the use reliability of joint with sealing function.

[0047] Specifically, the positioning member 400 is arranged at a side of the first valve core 300 away from the first opening, a middle position of the positioning member 400 is connected with a middle position of the first valve core 300, two positioning portions 410 are arranged along a radial direction of the first valve core 300, the two positioning portions 410 respectively extend out of the first valve core 300 along the radial direction of the first valve core 300, and the side wall of the gas outlet channel 120 is provided with two positioning grooves 121, the two positioning grooves 121 are symmetrically arranged, the positioning portions 410 are accommodated in the corresponding positioning grooves 121 and can abut against the side wall of the positioning grooves 121, so that the first valve core 300 can be coaxially arranged with the gas outlet channel 120, the situation that the first valve core 300 is dislocated with the first sealing member 200 to cause the sealing failure of the joint with the sealing function can be avoided, and the use reliability of the joint with the sealing function can be improved.

[0048] It should be noted that the positioning structure can also be a positioning protrusion arranged on the side wall of the gas outlet channel 120 and a positioning groove 121 arranged on the positioning member 400, the positioning protrusion is accommodated in the corresponding positioning hole 420 and can also position the first valve core 300, and details are not repeated here.

[0050] In some embodiments of the utility model, when the first valve core 300 is in the open state, the periphery of the side of the through hole 130 facing the second opening can abut against the side of the positioning member 400 away from the first valve core 300, the movement stroke of the first valve core 300 can be limited, the positioning shaft 310 can be prevented from being separated from the positioning hole 420, the position of the first valve core 300 can be effectively positioned, the situation that the first valve core 300 is dislocated with the first sealing member 200 to cause the first sealing member 200 and the first valve core 300 to fail to be sealingly matched can be avoided, and the use reliability of the joint with the sealing function can be improved.

[0051] Specifically, when the first valve core 300 is in the closed state, the user applies an external force to the second connecting pipe 820, so that the end of one end of the second connecting pipe 820 pushes and presses the first valve core 300 to move in the direction close to the through hole 130, so that the first valve core 300 is separated from the first sealing member 200, the movement stroke of the first valve core 300 is the minimum distance between the first valve core 300 and the periphery of the side of the through hole 130 facing the second opening when the first valve core 300 is in the closed state, the position of the first valve core 300 can be effectively positioned, the situation that the first valve core 300 is dislocated with the first sealing member 200 to cause the first sealing member 200 and the first valve core 300 to fail to be sealingly matched can be avoided, and the use reliability of the joint with the sealing function can be improved.

[0052] It should be noted that the sum of the length of the positioning shaft 310 and the length of the positioning hole 420 is greater than the minimum distance between the first valve core 300 and the periphery of the side of the through hole 130 facing the second opening when the first valve core 300 is in the closed state, no matter where the positioning member 400 and the first valve core 300 are located between the through hole 130 and the first sealing member 200, the positioning shaft 310 can be partially accommodated in the positioning hole 420, and the position of the first valve core 300 can be effectively positioned.

[0053] It should be noted that the side wall of the gas outlet channel 120 is provided with a avoiding groove, when the first valve core 300 is in the open state, the through hole 130 communicates with the second opening through the avoiding groove, the outer circumferential side of the first valve core 300 and the side wall of the avoiding groove facing the first valve core 300 are spaced apart to form a gap, and the gas flow entering from the second opening can flow out from the first opening through the gap, so as to facilitate the gas flow through the gas outlet channel 120.

[0054] In some embodiments of the utility model, the first valve core 300 includes a sealing part 330 and an abutting part 320, the abutting part 320 is arranged on one side of the sealing part 330, the positioning shaft 310 is arranged on the side of the sealing part 330 away from the abutting part 320, the abutting part 320 can abut with the end of the second connecting pipe 820, the sealing part 330 is sealingly matched with the first sealing member 200, the positioning shaft 310 is connected with the positioning member 400, the abutting part 320 is provided with a default groove 321, the default groove 321 can communicate with the second connecting pipe 820, and the high-pressure gas flow in the gas outlet channel 120 can be conveniently discharged.

[0055] Specifically, along the axial direction of the gas outlet channel 120, the abutting part 320-sealing part 330-positioning shaft 310 are sequentially connected, one side of the sealing part 330 is connected with the abutting part 320, some of the side of the sealing part 330 away from the abutting part 320 is connected with the positioning shaft 310, the opposite sides of the abutting part 320 are respectively provided with a default groove 321, the two default grooves 321 are symmetrically arranged, the gas flow of the gas outlet channel 120 flows into the second connecting pipe 820 through the default groove 321, on the one hand, the end of the second connecting pipe 820 can not directly act on the sealing part 330, on the other hand, the gas flow of the gas outlet channel 120 flows into the second connecting pipe 820 through the default groove 321, and the high-pressure gas flow in the gas outlet channel 120 can be conveniently discharged.

[0056] It should be noted that when the operator cuts the second connecting pipe 820, the end of the second connecting pipe 820 is mostly uneven structure, if the end of the second connecting pipe 820 directly abuts against the sealing portion 330, there is a situation that the force of the sealing portion 330 in the circumferential direction is uneven, which is easy to cause the first valve core 300 to be offset and dislocated, resulting in that the first valve core 300 and the first sealing element 200 cannot form a seal, by arranging the positioning shaft 310, the situation that the first valve core 300 is offset and dislocated can be avoided, and it can be ensured that the first valve core 300 and the first sealing element 200 can stably form a seal, which will not be described in detail here.

[0057] In order to improve the sealing performance of the second connecting pipe 820, the first sealing protrusion 220 is arranged on the inner wall of the first avoiding hole 210, the first sealing protrusion 220 is annular structure, when the second connecting pipe 820 is installed, the second connecting pipe 820 can be tightly attached to the inner wall of the first sealing protrusion 220, so as to improve the sealing performance of the second connecting pipe 820. It should be noted that the first sealing protrusion 220 can be configured with multiple, and multiple first sealing protrusions 220 can be arranged in parallel and spaced along the axial direction of the first sealing hole.

[0058] In order to improve the sealing performance of the first valve core 300, for example Figure 2 As shown, the first sealing element 200 is provided with a second sealing protrusion 230 on the side facing the first valve core 300, and the first valve core 300 abuts against the second sealing protrusion 230 when the first valve core 300 is in the closed state, which can improve the structural strength of the first sealing element, avoid the situation that the deformation of the periphery of the first avoiding hole 210 causes the sealing failure of the first valve core 300, and improve the use reliability of the joint with sealing function.

[0059] In order to increase the deformation amount of the second sealing protrusion 230, the thickness of the second sealing protrusion 230 gradually decreases in the direction close to the axis of the first avoiding hole 210, and the side of the second sealing protrusion 230 facing the first valve core 300 is a curved surface structure, when the first valve core 300 extrudes the first sealing element 200, the first valve core 300 is limited to contact the outer periphery of the first sealing protrusion 220, in the process of extruding the second sealing protrusion 230, the side of the second sealing protrusion 230 facing the first valve core 300 gradually deforms, the deformation amount of the second sealing protrusion 230 increases, so as to increase the contact area between the second sealing protrusion 230 and the first valve core 300, which can improve the sealing effect of the first valve core 300. Of course, in some specific embodiments, the side of the second sealing protrusion 230 facing the first valve core 300 can also be a bevel structure, which is not limited here.

[0060] In order to facilitate installation or disassembly of the second connecting pipe 820, the joint with the sealing function further comprises a first elastic member 510 and a first pressing block 520. The first elastic member 510 is accommodated in the air outlet channel 120, and the first elastic member 510 is used for clamping the second connecting pipe 820 extending into the air outlet channel 120. One end of the first pressing block 520 is accommodated in the air outlet channel 120, and the other end of the first pressing block 520 extends out of the joint body 100. The first pressing block 520 can be telescoped relative to the joint body 100, and can be deformed by telescoping to extrude the first elastic member 510, so that the first elastic member 510 is separated from the second connecting pipe 820 passing through the first pressing block 520, and the second connecting pipe 820 can be conveniently installed and disassembled.

[0061] Specifically, when the second connecting pipe 820 is installed, the second connecting pipe 820 passes through the first pressing block 520, the first elastic member 510 and the first sealing member 200 in sequence to enter the air outlet channel 120. The first elastic member 510 can clamp the second connecting pipe 820 extending into the air outlet channel 120, so as to fix the position of the second connecting pipe 820 in the joint body 100. When the second connecting pipe 820 is disassembled, the operator can press the other end of the first pressing block 520, so that the one end of the first pressing block 520 extrudes the first elastic member 510 to expand, so as to separate the first elastic member 510 from the second connecting pipe 820. The operator can pull out the second connecting pipe 820, which is simple, convenient and fast, and can facilitate installation and disassembly of the second connecting pipe 820.

[0062] In order to improve the sealing performance of the second connecting pipe 820, the joint with the sealing function further comprises a first sealing block 550 and a first fixing block 560. The first fixing block 560 is arranged at the second opening, and the first fixing block 560 is connected with the joint body 100 in a clamping manner. The first sealing block 550 is accommodated in the air outlet channel 120. The second connecting pipe 820 can pass through the first fixing block 560 and the first sealing block 550. One end of the first pressing block 520 is accommodated in the first fixing block 560. The outer side of the first elastic member 510 is clamped between the first sealing block 550 and the first fixing block 560. The inner side of the first sealing block 550 is provided with a third sealing protrusion 551. The third sealing protrusion 551 is arranged in a circumferential direction. The third sealing protrusion 551 can be tightly attached to the outer circumferential side of the second connecting pipe 820, so as to improve the sealing performance of the second connecting pipe 820.

[0063] In some embodiments of the utility model, the sealing part 330, the positioning shaft 310 and the abutting part 320 are of an integrated structure, which can reduce the number of molds, thereby reducing the production cost of the molds, and further reducing the production cost of the joint with the sealing function. It should be noted that,

[0064] As another embodiment, with reference toFigure 7 , Figure 8 The joint with sealing function can also be configured as a right-angle joint, and the axial direction of the air inlet channel 110 is perpendicular to the axial direction of the air outlet channel 120, for example Figure 8 As shown, the outlet channel 120 is provided with a first valve core 300 and a first sealing member 200, the inlet channel 110 is provided with a second valve core 700 and a second sealing member 600, the second sealing member 600 is accommodated in the inlet channel 110 and is provided with a second avoidance hole 610, the second valve core 700 is located between the second sealing member 600 and the through hole 130, when one end of the first connecting pipe 810 is inserted into the inlet channel 110, one end of the first connecting pipe 810 passes through the second avoidance hole 610 and is in contact with the second valve core 700. The abutment can push the second valve core 700 to move in the direction away from the second sealing member 600, so that the second valve core 700 opens the air inlet channel 110. In this way, the air inlet channel 110 and the air outlet channel 120 can be interchanged. The assembler does not need to identify the air inlet channel 110 and the air outlet channel 120 in advance, and can directly connect the two ends of the joint with the sealing function to the first connecting pipe 810 and the second connecting pipe 820 respectively, which can facilitate the assembler to assemble the first connecting pipe 810 and the second connecting pipe 820.

[0065] It should be noted that both the first sealing member 200 and the second sealing member 600 can be made of rubber or silicone material, which will not be described in detail here.

[0066] It should be noted that the specific structure of the second valve core 700 is the same as that of the first valve core 300 , and the specific structure of the second sealing member 600 is the same as that of the first sealing member 200 , which will not be repeated here.
