[0040] As described 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 with the power component is relatively harsh, the connecting pipe connected with the power component is prone to aging after long-term use. In order to reduce the waste of air source, the maintenance personnel need to close the electromagnetic valve before replacing the aging connecting pipe, which is not convenient for the maintenance personnel to replace the connecting pipe.

[0041] Referring to Figure 1 , Figure 3 , according to the first aspect of the present application, the joint with sealing function, wherein the first valve core 300 is in an open state, the joint with sealing function is configured as a straight-through joint, the straight-through joint has a cylindrical structure as a whole, the joint with sealing function comprises a joint body 100, a first sealing member 200 and a first valve core 300, two ends of the joint body 100 are respectively provided with an air inlet channel 110 and an air outlet channel 120, the air inlet channel 110 is communicated with the air outlet channel 120 through a through hole 130, the first sealing member 200 is accommodated in the air outlet channel 120, the first sealing member 200 is located between the through hole 130 and the second opening, the first sealing member 200 is provided with a first avoiding hole 210, when assembling the first connecting pipe 810, one end of the first connecting pipe 810 is inserted into the air inlet channel 110 through the first opening, the other end of the first connecting pipe 810 is communicated with the output end of the air compressor, when assembling the second connecting pipe 820, one end of the second connecting pipe 820 is inserted into the air outlet channel 120 through the second opening, and the end of one end of the second connecting pipe 820 pushes the first valve core 300 to move away from the first sealing member 200, so that the valve core is separated from the first sealing member 200, the first valve core 300 is in an open state, the other end of the second connecting pipe 820 is communicated with the input end of the power component of the automatic equipment, the assembler can increase the second connecting pipe 820 through the joint with sealing function, so that the overall length of the first connecting pipe 810 and the second connecting pipe 820 is increased.

[0042] Referring to Figure 2After long-time use, the second connecting pipe 820 is prone to aging, and a maintenance worker pulls the second connecting pipe 820 out of the gas outlet passage 120. Since 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 in a direction close to the first sealing member 200, so that the first valve core 300 is tightly attached to the periphery of the first avoiding hole 210, and the first valve core 300 is switched from the open state to the closed state. The gas in the gas outlet passage 120 cannot continue to be discharged, which can reduce the waste of the gas source, the maintenance worker does not need to close the electromagnetic valve on the first connecting pipe 810, the maintenance operation of the maintenance worker can be simplified, and the maintenance worker can conveniently replace the second connecting pipe 820.

[0043] It should be noted that the fluid flowing in the joint with a sealing function can be a liquid or a gas, which is not limited herein.

[0044] Reference Figures 4 to 6 In some embodiments of the present application, a positioning structure is arranged between the first valve core 300 and the joint body 100, and the positioning structure is used to coaxially arrange the first valve core 300 and the gas outlet passage 120, so that the mispositioning of the first valve core 300 and the first sealing member 200 to cause the sealing failure of the joint with a sealing function can be avoided, and the use reliability of the joint with a sealing function can be improved.

[0045] In some embodiments of the present application, the positioning structure includes a positioning groove 121 arranged on the side wall of the gas outlet passage 120 and a positioning member 400 arranged on the first valve core 300. One end of the positioning member 400 is provided with a positioning portion 410, the positioning portion 410 is accommodated in the positioning groove 121 and can abut against the side wall of the positioning groove 121, so that the first valve core 300 is coaxially arranged with the gas outlet passage 120, the mispositioning of the first valve core 300 and the first sealing member 200 to cause the sealing failure of the joint with a sealing function can be avoided, and the use reliability of the joint with a sealing function can be improved.

[0046] Specifically, the positioning member 400 is arranged on the side of the first valve core 300 away from the first opening, the middle position of the positioning member 400 is connected with the middle position of the first valve core 300, two positioning portions 410 are arranged along the radial direction of the first valve core 300, the two positioning portions 410 respectively protrude from the first valve core 300 along the radial direction of the first valve core 300, the side wall of the gas outlet passage 120 is provided with two positioning grooves 121, the two positioning grooves 121 are symmetrically arranged, the positioning portion 410 is accommodated in the corresponding positioning groove 121 and can abut against the side wall of the positioning groove 121, so that the first valve core 300 can be coaxially arranged with the gas outlet passage 120, the mispositioning of the first valve core 300 and the first sealing member 200 to cause the sealing failure of the joint with a sealing function can be avoided, and the use reliability of the joint with a sealing function can be improved.

[0047] It should be noted that the positioning structure can also be a positioning protrusion arranged on the side wall of the air 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 the first valve core 300 can also be positioned, which will not be described here.

[0048] In some embodiments of the present application, the positioning member 400 is provided with a positioning hole 420, and the first valve core 300 is provided with a positioning shaft 310, the positioning shaft 310 is movably arranged in the positioning hole 420.

[0049] In some embodiments of the present application, 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 to avoid the positioning shaft 310 from being separated from the positioning hole 420, the position of the first valve core 300 can be effectively positioned to avoid the situation that the first valve core 300 and the first sealing member 200 are misaligned to cause the first sealing member 200 and the first valve core 300 cannot be sealed, and the use reliability of the joint with sealing function can be improved.

[0050] 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 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 to avoid the situation that the first valve core 300 and the first sealing member 200 are misaligned to cause the first sealing member 200 and the first valve core 300 cannot be sealed, and the use reliability of the joint with sealing function can be improved.

[0051] 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 the positioning member 400 and the first valve core 300 are in any position 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.

[0052] It should be noted that the side wall of the air outlet passage 120 is provided with a relief groove, when the first valve core 300 is in the open state, the through hole 130 communicates with the second opening through the relief groove, the outer circumferential side of the first valve core 300 is spaced apart from the side wall of the relief groove facing the first valve core 300 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 air outlet passage 120.

[0053] In some embodiments of the application, the first valve core 300 includes a sealing portion 330 and an abutting portion 320, the abutting portion 320 is arranged on one side of the sealing portion 330, the positioning shaft 310 is arranged on the side of the sealing portion 330 away from the abutting portion 320, the abutting portion 320 can abut with the end of the second connecting pipe 820, the sealing portion 330 is sealingly matched with the first sealing element 200, the positioning shaft 310 is connected with the positioning element 400, and the abutting portion 320 is provided with a default groove 321, which can communicate with the second connecting pipe 820, so as to facilitate the discharge of high-pressure gas flow in the air outlet passage 120.

[0054] Specifically, along the axial direction of the air outlet passage 120, the abutting portion 320, the sealing portion 330 and the positioning shaft 310 are connected in sequence, one side of the sealing portion 330 is connected with the abutting portion 320, and the other side of the sealing portion 330 away from the abutting portion 320 is connected with the positioning shaft 310, the opposite sides of the abutting portion 320 are respectively provided with a default groove 321, the two default grooves 321 are symmetrically arranged, and the gas flow in the air outlet passage 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 portion 330, on the other hand, the gas flow in the air outlet passage 120 flows into the second connecting pipe 820 through the default groove 321, which can facilitate the discharge of high-pressure gas flow in the air outlet passage 120.

[0055] 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 with the sealing portion 330, the sealing portion 330 will be unevenly stressed at some position in the circumferential direction, 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 first valve core 300 can be prevented from being offset and dislocated, and the first valve core 300 and the first sealing element 200 can stably form a seal, which will not be described in detail here.

[0056] In order to improve the sealing performance of the second connecting pipe 820, a first sealing protrusion 220 is arranged on the inner wall of the first avoiding hole 210, the first sealing protrusion 220 is in a ring 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 first sealing protrusions 220, and the multiple first sealing protrusions 220 can be arranged in parallel along the axial direction of the first sealing hole.

[0057] In order to improve the sealing performance of the first valve core 300, for example Figure 2 As shown in the figure, the first sealing member 200 is provided with a second sealing protrusion 230 on the side facing the first valve core 300, when the first valve core 300 is in the closed state, the first valve core 300 abuts against the second sealing protrusion 230, which can improve the structural strength of the first sealing member, avoid the deformation of the periphery of the first avoiding hole 210 leading to the sealing failure of the first valve core 300, and improve the use reliability of the joint with sealing function.

[0058] In order to increase the deformation amount of the second sealing protrusion 230, the thickness of the second sealing protrusion 230 gradually decreases along 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 in a curved surface structure, when the first valve core 300 extrudes the first sealing member 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 in a bevel structure, which is not limited here.

[0059] In order to facilitate the installation or disassembly of the second connecting pipe 820, the joint with sealing function of the embodiment of the application 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, 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, the other end of the first pressing block 520 extends out of the outside of the joint main body 100, the first pressing block 520 can be telescopic relative to the joint main body 100, and can extrude the first elastic member 510 to deform, so as to separate the first elastic member 510 from the second connecting pipe 820 passing through the first pressing block 520, which can facilitate the installation and disassembly of the second connecting pipe 820.

[0060] 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, and the first elastic member 510 can be clamped to 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 one end of the first pressing block 520 pushes and expands the first elastic member 510 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 the installation and disassembly of the second connecting pipe 820.

[0061] In order to improve the sealing performance of the second connecting pipe 820, the joint with a sealing function in the embodiment of the present application 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 by clamping. 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 tightly contact the outer circumferential side of the second connecting pipe 820, so as to improve the sealing performance of the second connecting pipe 820.

[0062] In some embodiments of the present application, 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 the production cost of the joint with a sealing function. It should be noted that,

[0063] As another embodiment, referring to Figure 7 , Figure 8 The joint with a sealing function can also be configured as a right-angle joint. The axial direction of the air inlet channel 110 and the axial direction of the air outlet channel 120 are arranged perpendicularly, for example Figure 8As shown, the first valve core 300 and the first sealing member 200 are arranged in the outlet passage 120, the second valve core 700 and the second sealing member 600 are arranged in the inlet passage 110, the second sealing member 600 is arranged in the inlet passage 110 and is provided with a second avoiding hole 610, and 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 passage 110, the one end of the first connecting pipe 810 passes through the second avoiding hole 610 and abuts against the second valve core 700, so that the second valve core 700 is pushed to move away from the second sealing member 600, and the second valve core 700 opens the inlet passage 110. In this way, the inlet passage 110 and the outlet passage 120 can be interchanged, the assembler does not need to identify the inlet passage 110 and the outlet passage 120 in advance, and can directly connect the two ends of the joint with sealing function with the first connecting pipe 810 and the second connecting pipe 820 respectively, so that the assembler can conveniently assemble the first connecting pipe 810 and the second connecting pipe 820.

[0064] It should be noted that the first sealing member 200 and the second sealing member 600 can be made of rubber or silicone, which will not be described in detail here.
