Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning technology, specifically to a high-sealing automotive air conditioning condenser piping assembly. Background Technology

[0002] Automotive air conditioning is a device that regulates the air quality and temperature in the passenger compartment or driver's cabin to achieve a comfortable standard. The evaporator is a crucial component of the four main refrigeration units. Low-temperature condensed liquid passes through the evaporator, exchanging heat with the outside air, vaporizing and absorbing heat to achieve a cooling effect. The condenser coil is used for fluid transport; condenser coils are mostly composed of interconnected metal pipes and hoses.

[0003] Most existing condenser pipes are fixed to the vehicle body by welding at one end, while the condenser pipes are connected to each other by bolts or threads. This makes the connection of condenser pipes require a lot of time for the staff. In addition, the use of the car air conditioning compressor will cause the condenser pipes to vibrate. Vibration will affect the stability of the condenser pipe connection. At the same time, vibration will generate noise and affect the NVH performance of the car. Utility Model Content

[0004] The purpose of this invention is to provide a high-sealing automotive air conditioning condenser piping assembly to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-sealing automotive air conditioning condenser piping assembly, comprising a first condenser pipe, a second condenser pipe at one end of the first condenser pipe, a connector on the first condenser pipe, the connector being fixedly connected to one end of an insert pipe, the outer side of the insert pipe being fixedly connected to a sealing ring, the outer side of the insert pipe being fixedly connected to a sealing collar, the outer side of the first condenser pipe being fixedly connected to a limiting rod, a rotating cylinder being provided on the outer side of the connector, a limiting groove being formed on the outer side of the connector, the side of the connector being fixedly connected to an inner sleeve, a movable tube being sleeved inside the inner sleeve, and the side of the connector being fixedly connected to a buffer rubber sleeve.

[0006] Preferably, one end of the first condenser tube is connected and fixed to the second condenser tube via a connector, the other end of the first condenser tube is fixedly connected to the connector, and the inside of the first condenser tube is inserted into the outside of the insert tube.

[0007] Preferably, a sealing ring and a sealing collar are respectively provided on both sides of the insertion tube, and the sealing collar has an inclined surface on its side.

[0008] Preferably, two symmetrical limiting grooves are provided on the outer side of the connector, the connector slides with the outer side of the limiting rod through the limiting grooves, the outer side of the connector is rotatably connected to the rotating drum, and a torsion spring is fixedly installed on the inner wall of the rotating drum.

[0009] Preferably, a slot is provided on the side of the rotating drum. The slot is an L-shaped slot and slides with the outer side of the limiting rod.

[0010] Preferably, a corrugated hose is fitted inside the buffer rubber sleeve, and both ends of the corrugated hose are respectively connected and fixed to the connector. An inner sleeve is fitted inside the corrugated hose, and the inner sleeve slides in conjunction with the movable tube.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention features a limiting rod at one end of the condenser tube, which is connected to the condenser tube via a connecting end. An insert tube is used to enhance the sealing effect by working with a sealing ring and a sealing collar inside the condenser tube. By rotating the rotating cylinder, the limiting rod moves into the slot, which then secures the connector to the condenser tube, preventing the condenser tube from loosening due to vibration. The connector further reduces the difficulty of disassembling and installing the condenser tube, improving its practical performance.

[0013] This invention also incorporates a buffer rubber sleeve on the outside of the corrugated hose to cushion the vibration of the condenser tube. The rubber buffer sleeve ensures the flexibility of the connector while further enhancing the cushioning and shock absorption effect. At the same time, the inner sleeve works in conjunction with the moving tube to ensure a sealing effect and the stability of the condenser tube, thus extending the service life of the condenser tube.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a high-sealing automotive air conditioning condenser piping assembly, including a condenser pipe 1, a condenser pipe 3 at one end of the condenser pipe 1, one end of the condenser pipe 1 being connected and fixed to the condenser pipe 3 via a connector 4, and the other end of the condenser pipe 1 being welded and fixed to the connector 2. The connector 2 facilitates the connection and fixation of the condenser pipe 1 and the condenser pipe 3, reducing the actual connection difficulty.

[0022] The condenser tube 1 is inserted into the outer side of the insert tube 5. The connector 4 is welded to one end of the insert tube 5. The outer side of the insert tube 5 is connected and fixed to the sealing ring 6, and also welded to the sealing collar 7. Sealing rings 6 and 7 are respectively installed on both sides of the insert tube 5. Both sealing rings 6 and 7 are made of rubber, and the sealing collar 7 has a beveled side. When the insert tube 5 is inserted into the condenser tube 1, the sealing collar 7 fits against the inner wall of the condenser tube 1, sealing the connection between the condenser tube 1 and the insert tube 5 to prevent dust and internal leakage. The cooperation of the sealing rings 6 and 7 effectively enhances the sealing performance, preventing leakage from the condenser tube 1.

[0023] The condenser tube 1 is welded and fixed to two symmetrical limiting rods 8 on its outer side. Two symmetrical limiting grooves 12 are opened on the outer side of the connector 4. The connector 4 slides with the limiting rods 8 through the limiting grooves 12. A retaining groove 10 is opened on the side of the rotating cylinder 9. The retaining groove 10 is an L-shaped groove that slides with the limiting rods 8. The positions of the retaining groove 10 and the limiting groove 12 are adapted to allow the limiting rods 8 to slide simultaneously within both the retaining groove 10 and the limiting groove 12. The limiting groove 12 is a straight groove, allowing the rotating cylinder 9 to rotate by driving the retaining groove 10 from the outside of the connector 4.

[0024] The connector 4 has an annular groove on its outer side, through which it is rotatably connected to the rotating cylinder 9. A torsion spring 11 is fixedly installed within the annular groove. The spring force of the torsion spring 11 keeps the rotating cylinder 9 within the annular groove. The rotating cylinder 9 drives the retaining groove 10 to rotate, allowing the limiting rod 8 to slide within the retaining groove 10. This rotation of the limiting rod 8 into the retaining groove 10 secures it, preventing it from detaching. Simultaneously, the retaining rod 8 in the limiting groove 12 prevents the condenser tube 1 and connector 4 from loosening due to vibration. During disassembly, rotating the rotating cylinder 9 aligns the limiting groove 12 with the retaining groove 10, allowing the condenser tube 1 to be easily pulled out from the outside of the insertion tube 5.

[0025] The connector 4 is welded and fixed to the inner sleeve 14 on its side. A movable tube 15 is fitted inside the inner sleeve 14. Both the inner sleeve 14 and the movable tube 15 are made of rubber. The inner sleeve 14 and the movable tube 15 ensure that the connector 4 can rotate freely, while the sliding friction between the inner sleeve 14 and the movable tube 15 also provides a buffering and shock-absorbing effect.

[0026] The connector 4 is welded and fixed to the side of the buffer rubber sleeve 16. A corrugated hose 13 is installed inside the buffer rubber sleeve 16. Both ends of the corrugated hose 13 are connected and fixed to the connector 4. An inner sleeve 14 is installed inside the corrugated hose 13. The inner sleeve 14 is in sliding fit with the moving tube 15.

[0027] Working principle: In use, condenser tube 1 is connected and fixed to the target location via connecting end 2 using bolts or welding. Then, the insert tube 5 inside the connector 4 is inserted into condenser tube 1. The connector 4 is sealed by the beveled surfaces of the sealing ring 6 and sealing collar 7. At the same time, the limiting rod 8 is moved into the slot 10 and the limiting groove 12. Then, the spring force of the torsion spring 11 causes the rotating drum 9 to rotate, which drives the limiting rod 8 to move into the slot 10, thus preventing the limiting rod 8 from disengaging from the slot 10. This connects and fixes condenser tube 1 and connector 4. Similarly, condenser tube 2 3 is connected and fixed to the other end of connector 4. Connector 4 effectively reduces the difficulty of connecting condenser tube 1 and condenser tube 2 3, and facilitates subsequent disassembly, maintenance and repair by staff. When condenser tube 1 vibrates, the corrugated hose 13 will expand and contract, and the impact force will be buffered and absorbed by the deformation of the buffer rubber sleeve 16. This ensures the stability of condenser tube 1 during use and prevents loosening caused by vibration of condenser tube 1, thus reducing its service life.
