Problems solved by technology

This form of sealing structure requires high dimensional accuracy, and the sealing ring is easy to be scratched and damaged during transportation and assembly, which leads to high processing costs of the welded structure, and is prone to leakage and high temperature in the subsequent welding process. There are problems such as the size of the back is out of tolerance, which needs to be improved

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 ...

Abstract

The invention discloses an air conditioner high-low pressure pipe assembly, and relates to the technical field of automobile air conditioner pipelines. The air conditioner high-low pressure pipe assembly comprises a high-low pressure pipe fitting and an extrusion sealing block; the extrusion sealing block is provided with a through hole for the high-low pressure pipe fitting to penetrate through and is used for extrusion sealing of the pipe end of the high-low pressure pipe fitting; and a limiting ring abutting against the extrusion sealing block is arranged at the end, penetrating through thethrough hole, of the high-low pressure pipe fitting, a rubber ring with one side abutting against the limiting ring and the other side used for extrusion sealing is connected to the end, penetratingthrough the through hole, of the high-low pressure pipe fitting in a sleeving mode, and a metal ring is connected to the rubber ring in a sleeving mode. The pipe end of the high-low pressure pipe fitting is sealed, the effect of preventing the high-low pressure pipe fitting from being separated from the extrusion sealing block is achieved by abutting against the extrusion sealing block through limiting, one side of the rubber ring abuts against the limiting ring, the other side of the rubber ring is used for extrusion sealing, the extrusion sealing effect is achieved after the extrusion sealing block is installed and fixed, and the effects that the product cost is remarkably reduced, and the sealing quality and convenience are remarkably improved are achieved.

Description

technical field [0001] The invention relates to the technical field of automobile air-conditioning pipelines, and more specifically relates to an air-conditioning high and low pressure pipe assembly. Background technique [0002] The high and low pressure pipes of automobile air conditioners are composed of high pressure pipes and low pressure pipes. Under the action of the blower, the air is cooled by the evaporator and then blown into the car to achieve cooling. In the evaporator, the refrigerant is vaporized into gas, and the gas is compressed by the compressor. The high-temperature and high-pressure gas enters the condenser through the high-pressure pipe to condense into a liquid, and then flows through the expansion valve through the high-pressure pipe to the evaporator after drying through the liquid storage drying filter. [0003] In the prior art, the end structure of the high and low pressure pipes of the automobile air conditioner is extruded and sealed by a welded...
