Embodiment 1
[0029] Such as figure 1 As shown, an air conditioner high and low pressure pipe assembly includes a high and low pressure pipe fitting 1 and an extruded sealing block 2 . The extrusion sealing block 2 is provided with a perforation for the high and low pressure pipe fittings 1 to pass through, and is used for the extrusion sealing of the pipe end of the high and low pressure pipe fittings 1; Positioning ring 11, and sleeved with a rubber ring 4 that abuts against the limiting ring 11 on one side and squeezes and seals on the other side. The block 2 is abutted to prevent the high and low pressure pipe fittings 1 from detaching from the extruded sealing block 2, and then the rubber ring 4 is used to extrude and seal the other side by abutting the limit ring 11 on one side. After the sealing block 2 is pressed, the extrusion sealing effect is realized, which has the effects of significantly reducing product cost and significantly improving sealing quality and convenience. It sh...
Embodiment 2
[0034] The difference between the second embodiment and the first embodiment is that the rubber ring 4 in the second embodiment is the second sealing ring 4b. Both sides of the second sealing ring 4b are provided with second sealing convex rings. The second sealing protruding ring 44 protrudes from the metal ring 3 , and the second sealing protruding ring 44 on one side abuts against the limiting ring 11 , and the second sealing protruding ring 44 on the other side is used for extrusion sealing. Therefore, the second sealing bead 44 passing through the two sides of the second sealing ring 4b respectively protrudes from the corresponding side, and the second sealing bead 44 on one side abuts against the limit ring 11, and the second sealing bead 44 on the other side The second sealing protruding ring 44 is used for extrusion sealing, thereby forming a stable protection for the second sealing ring 4b, which has the effects of convenient installation, significantly improved seali...
Embodiment 3
[0036] The difference between the third embodiment and the first embodiment is that the rubber rings 4 in the third embodiment are the first sealing ring 4a and the second sealing ring 4b. Both sides of the first sealing ring 4a are provided with first sealing protruding rings 43 . The first sealing protruding ring 43 protrudes from the metal ring 3, and the first sealing protruding ring 43 on one side abuts against the limit ring 11, and the first sealing protruding ring 43 on the other side is used for extrusion sealing; Both sides of the second sealing ring 4 b are provided with second sealing protruding rings 44 . The second sealing protruding ring 44 protrudes from the metal ring 3, and the second sealing protruding ring 44 on one side abuts against the limit ring 11, and the second sealing protruding ring 44 on the other side is used for extrusion seal. Therefore, the first sealing ring 4a and the second sealing ring 4b are matched and connected with the corresponding ...
