Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of air tightness detection, in particular to an air tightness detection quick connector. Background Art
[0002] Air tightness testing refers to the detection of gas leakage in an object or system. It is mainly used to ensure whether the sealing performance of a certain equipment, container or structure meets the requirements to prevent gas leakage or external contaminants from entering, and air tightness testing usually detects leaks by introducing gas or pressure difference.
[0003] In the market, when conducting air tightness testing, it is often necessary to use a rubber tube to connect the items to be tested. This method cannot better meet the needs of users when more precise testing is required, and it cannot perform air tightness testing more effectively and quickly during mass production testing. Therefore, technical personnel in this field provide an air tightness testing quick connector to solve the problems raised in the above background technology. Utility Model Content
[0004] The purpose of the utility model is to provide an air tightness detection quick connector to solve the problems raised in the above background technology.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] A quick connector for air tightness detection, comprising a first limiting plate, a first sealing gasket, a second sealing gasket, a connector, a venting groove, an air inlet, an auxiliary block, an air supply pipe, an air supply assembly, a test connector, a sliding groove, an air bag, a fixed snap-in bead, a second limiting plate, a sealing ring and an air outlet groove, wherein a sliding groove and an air outlet groove are provided in the connector, an air supply pipe is slidably connected in the air outlet groove, a second limiting plate is fixedly connected to the surface of the air supply pipe, and the second limiting plate is slidably connected in the sliding groove, a sealing ring is fixedly connected to the lower end of the second limiting plate, and the sealing ring is snap-fitted in the air outlet groove, and the inner side of the sliding groove An air inlet is fixedly connected to the wall, a ventilation groove is arranged at one end of the air inlet, an airbag is fixedly connected to one end of the ventilation groove, and the airbag is fixedly connected to the inner wall of the sliding groove, a plurality of evenly distributed fixed clamping beads are fixedly connected to the surface of the airbag, the ventilation groove is arranged in the connecting head, an air supply assembly is fixedly connected to one end of the air supply pipe, an auxiliary block is fixedly connected to the surface of the connecting head, a test joint is slidably connected in the sliding groove, a second sealing gasket and a first sealing gasket are fixedly connected to the surface of the test joint, and the airbag is clamped between the second sealing gasket and the first sealing gasket, and a first limit plate is fixedly connected to the surface of the test joint.
[0007] By adopting the above technical solution,
[0008] Compared with the prior art, the beneficial effects of the utility model are as follows: the test connector is connected to the device to be tested, and the air supply component is started to ventilate the air supply pipeline. The auxiliary block is used to move the connector so that the second limit plate drives the sealing ring to disengage from the air outlet groove, and then the test connector is sent into the sliding groove. Since the first sealing pad is smaller than the sliding groove and larger than the second sealing pad, after the second sealing pad passes over the airbag, the first sealing pad abuts against the upper surface of the airbag. At this time, when the airbag is clamped between the first sealing pad and the second sealing pad, the air supply pipeline is pulled to clamp the sealing ring back into the air outlet groove. Since the interior of the sliding groove is relatively sealed at this time, the gas can enter the ventilation groove through the air inlet and be filled into the airbag from the ventilation groove. The airbag is filled with gas and is stuck between the first sealing pad and the second sealing pad, and the fixing card is also caught between the first sealing pad and the second sealing pad, thereby providing a certain fixing effect for the test joint; when disassembly is required, the sealing ring can be separated from the air outlet groove by toggling the connecting head, thereby releasing the sealing environment of the sliding groove, allowing the gas inside the airbag to leak, and then the test joint can be separated from the sliding groove. Since the utility model is provided with an airbag, when the test joint is connected, the test joint can be fixed by inflating the airbag, thereby making the connection more convenient, and making the connection and disassembly more convenient and quick; at the same time, when necessary, the special test joint can be replaced during the production of the test device, which can further improve the efficiency of subsequent tests.

The connecting head 4 is provided with a sliding groove 11 and an air outlet groove 16, and the air outlet groove 16 is slidably connected with the air supply pipe 8. The surface of the air supply pipe 8 is fixedly connected with the second limiting plate 14, and the second limiting plate 14 is slidably connected in the sliding groove 11. The lower end of the second limiting plate 14 is fixedly connected with a sealing ring 15, and the sealing ring 15 is snapped on the air outlet In the groove 16, an air inlet 6 is fixedly connected to the inner wall of the sliding groove 11, and a ventilation groove 5 is arranged at one end of the air inlet 6. An air bag 12 is fixedly connected to one end of the ventilation groove 5, and the air bag 12 is fixedly connected to the inner wall of the sliding groove 11. A plurality of evenly distributed fixed snap-in beads 13 are fixedly connected to the surface of the air bag 12. The ventilation groove 5 is arranged in the connecting head 4, an air supply assembly 9 is fixedly connected to one end of the air supply pipe 8, an auxiliary block 7 is fixedly connected to the surface of the connecting head 4, a test joint 10 is slidably connected in the sliding groove 11, a second sealing gasket 3 and a first sealing gasket 2 are fixedly connected to the surface of the test joint 10, and the air bag 12 is snapped between the second sealing gasket 3 and the first sealing gasket 2, and a first limit plate 1 is fixedly connected to the surface of the test joint 10.
[0015] The working principle of the utility model is:
[0016] The utility model relates to an air tightness detection quick connector, in which a test connector 10 is connected to a device to be detected, and at this time, the air supply component 9 is started to ventilate the air supply pipe 8, and the connecting head 4 is moved with the help of the auxiliary block 7, so that the second limit plate 14 drives the sealing ring 15 to disengage from the air outlet groove 16, and then the test connector 10 is sent into the sliding groove 11. Since the first sealing gasket 2 is smaller than the sliding groove 11 and larger than the second sealing gasket 3, after the second sealing gasket 3 passes over the airbag 12, the first sealing gasket 2 abuts against the upper surface of the airbag 12. At this time, when the airbag 12 is clamped between the first sealing gasket 2 and the second sealing gasket 3, the air supply pipe 8 is pulled to clamp the sealing ring 15 into the air outlet groove 16 again. Since the interior of the sliding groove 11 is relatively sealed at this time, the gas can enter the interior of the ventilation groove 5 through the air inlet 6, and the ventilation groove 5 is filled with gas. The airbag 12 is filled with gas and is stuck between the first sealing pad 2 and the second sealing pad 3. At the same time, the fixing card bead 13 is also stuck between the first sealing pad 2 and the second sealing pad 3, thereby providing a certain fixing effect for the test connector 10. When disassembly is required, the sealing ring 15 can be separated from the air outlet groove 16 by toggling the connecting head 4, thereby releasing the sealing ring 15 environment of the sliding groove 11, so that the gas inside the airbag 12 leaks, and then the test connector 10 can be separated from the sliding groove 11. Since the utility model is provided with the airbag 12, when the test connector 10 is connected, the test connector 10 can be fixed by inflating the airbag 12, thereby making the connection more convenient, and making the connection and disassembly more convenient and quick. At the same time, when necessary, the special test connector 10 can be replaced during the production of the test device, which can further improve the efficiency of subsequent tests.
