Description

Technical Field

[0001] This utility model belongs to the field of pipeline equipment technology, specifically relating to a high corrosion-resistant aluminum rigid pipe for automotive air conditioning. Background Technology

[0002] An automotive air conditioning system is a device that cools, heats, ventilates, and purifies the air inside a vehicle. It provides a comfortable riding environment for passengers, reduces driver fatigue, and improves driving safety. The automotive air conditioning system consists of a compressor, condenser, receiver-drier, expansion valve, evaporator, and blower. These components are connected by aluminum tubing and high-pressure rubber hoses to form a closed system. During operation, the refrigerant circulates within this closed system in different states. The aluminum tubing transports high-pressure, low-pressure gaseous, or liquid refrigerant.

[0003] In the existing technology, due to the large number of uncertain factors in the vehicle driving environment, once the road surface is uneven, the vehicle is prone to large shaking, which can easily cause damage to the welded joints of the connecting pipes in the car air conditioner, thus affecting the normal use of the car air conditioner. Utility Model Content

[0004] The purpose of this invention is to solve the aforementioned technical problems in the existing technology and provide a high corrosion-resistant aluminum rigid pipe for automotive air conditioning. This is achieved by welding a U-shaped pipe section to a straight pipe section, then fixing a mounting base at the bottom of the U-shaped pipe section, and fixing a clamping component at the weld joint. The clamping component is then connected to the mounting base. The synergistic effect of the bottom mounting base and the clamping component at the connection joint gives the pipe excellent vibration resistance and structural stability. The mounting base effectively absorbs the impact load during pipeline operation, while the clamping component prevents deformation at the connection joint due to stress concentration, thereby significantly extending the service life of the pipe.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A high corrosion-resistant aluminum rigid pipe for automotive air conditioning includes a U-shaped pipe section and a straight pipe section. Straight pipe sections are welded and fixed to both ends of the U-shaped pipe section. A fixing seat is fixedly connected to the bottom of the U-shaped pipe section. A clamping component is fixedly connected to the connection between the straight pipe section and the U-shaped pipe section, and the fixing seat and clamping component are fixedly connected. This invention, by welding the U-shaped pipe section and the straight pipe section together, and then fixing the fixing seat at the bottom of the U-shaped pipe section, and fixing the clamping component at the weld joint, connects the clamping component to the fixing seat. The synergistic effect of the bottom fixing seat and the connection clamping component gives the pipe excellent vibration resistance and structural stability. The fixing seat effectively absorbs the impact load during pipeline operation, while the clamping component prevents deformation due to stress concentration at the connection, thereby greatly extending the service life of the pipe.

[0007] Furthermore, both ends of the U-shaped pipe section are equipped with plug-in parts, which are inserted into the straight pipe section and then welded in place. After the plug-in parts are inserted into the straight pipe section, they are then welded to form a double-sealed structure. This increases the contact surface area between the U-shaped pipe section and the straight pipe section, improving the connection strength and sealing performance. Both the U-shaped pipe section and the straight pipe section are made of aluminum, which provides high strength and corrosion resistance.

[0008] Furthermore, a splicing seat is fixedly connected to the fixed base, and the U-shaped pipe segment is clamped between the fixed base and the splicing seat. By splicing the upper and lower parts, the fixed base and the splicing seat are fixed in a 360° wrap-around manner, distributing the force on the U-shaped pipe segment to the entire support surface and preventing metal fatigue cracks in the U-shaped pipe segment due to long-term vibration.

[0009] Furthermore, the top surface of the fixing seat is provided with an arc-shaped groove, which matches the bottom of the U-shaped pipe section. Correspondingly, the bottom of the splicing seat is provided with a splicing groove, which matches the top of the U-shaped pipe section. After the fixing seat and the splicing seat are fixed, the arc-shaped groove and the splicing groove connect to form a limiting groove, which confines the U-shaped pipe section within the limiting groove. The arc-shaped groove increases the contact area and eliminates localized stress concentration in the U-shaped pipe section.

[0010] Furthermore, the top of the fixing base is evenly distributed with connecting screws, the top of which passes through the splicing base, and a connecting nut is screwed into the top of the connecting screw, which is then tightened onto the splicing base. The arrangement of the connecting screws and the connecting nut facilitates the assembly and disassembly of the fixing base and the splicing base.

[0011] Furthermore, the clamping component includes an upper clamping seat and a lower clamping seat. The top of the lower clamping seat has a first groove, and the bottom of the connection between the U-shaped pipe section and the straight pipe section rests in the first groove. The bottom of the upper clamping seat has a second groove, and the top of the connection between the U-shaped pipe section and the straight pipe section rests in the second groove. After being fixed by the upper and lower clamping seats, the connection between the U-shaped pipe section and the straight pipe section is clamped and fixed, increasing the stability of the connection between the U-shaped pipe section and the straight pipe section.

[0012] Furthermore, two connecting screws are provided on both sides of the top of the lower clamping seat. The top of the connecting screws passes through the upper clamping seat, and a connecting nut is screwed into the top of the connecting screw. The connecting nut is tightened onto the upper clamping seat. Through the cooperation of the connecting screws and the connecting nuts, the lower clamping seat and the upper clamping seat are fixedly connected, while facilitating the assembly and disassembly of the upper clamping seat and the lower clamping seat.

[0013] Furthermore, an adjusting rod is fixedly connected to the fixed base, and a through hole is correspondingly provided at the bottom of the lower clamping seat. The adjusting rod passes through the through hole, and a limiting component is provided on the adjusting rod to limit and fix the lower clamping seat on the adjusting rod. The adjusting rod can be adjusted according to the position of the connection between the U-shaped pipe section and the straight pipe section to adjust the clamping component.

[0014] Furthermore, the limiting component includes two adjusting seats, which are slidably connected to the adjusting rod. The lower clamping seat is located between the two adjusting seats. One end of each adjusting seat has a tightening end that abuts against the lower clamping seat. The other end of each adjusting seat has a tightening screw. When the lower clamping seat is limited to the adjusting rod, the tightening screw tightens against the adjusting rod. The tightening screw is used to fix the adjusting seat to the adjusting rod. The two adjusting seats drive the lower clamping seat to slide and adjust. After adjustment, the adjusting seat and the adjusting rod are fixedly connected by the tightening screw, thereby limiting the position of the lower clamping seat.

[0015] Furthermore, a limit block is fixedly connected to the end of the adjusting rod. The limit block serves to limit the movement of the lower clamping seat and the adjusting seat, preventing them from slipping off the adjusting rod.

[0016] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0017] This invention fixes a U-shaped pipe section to a straight pipe section by welding, then installs a fixing seat at the bottom of the U-shaped pipe section, and fixes a clamping component at the weld joint, connecting the clamping component to the fixing seat. The synergistic effect of the bottom fixing seat and the clamping component at the connection gives the pipeline excellent vibration resistance and structural stability. The fixing seat effectively absorbs the impact load during pipeline operation, while the clamping component prevents deformation at the connection due to stress concentration, thereby greatly extending the service life of the pipeline.

[0018] In this invention, both ends of the U-shaped pipe section are provided with insertion parts, which are inserted into the straight pipe section and then welded in place. After the insertion parts are inserted into the straight pipe section, they are then welded to form a double-sealed structure. This also increases the contact surface between the U-shaped pipe section and the straight pipe section, improving the connection strength and sealing performance.

[0019] In this invention, a fixed base is fixedly connected to an adjusting rod. A through hole is correspondingly formed at the bottom of the lower clamping seat, through which the adjusting rod passes. A limiting component is provided on the adjusting rod, which limits and fixes the lower clamping seat to the adjusting rod. The adjusting rod can be adjusted according to the position of the connection between the U-shaped pipe section and the straight pipe section. The limiting component includes two adjusting seats slidably connected to the adjusting rod. The lower clamping seat is located between the two adjusting seats. One end of each adjusting seat has a tightening end that abuts against the lower clamping seat. The other end of each adjusting seat has a tightening screw. When the lower clamping seat is limited to the adjusting rod, the tightening screw tightens against the adjusting rod. The tightening screw is used to fix the adjusting seat to the adjusting rod. The two adjusting seats drive the lower clamping seat to slide and adjust. After adjustment, the tightening screw fixes the adjusting seat to the adjusting rod, thereby limiting the position of the lower clamping seat. Attached Figure Description

Detailed Implementation

[0029] like Figures 1 to 7 As shown, this utility model discloses a high corrosion-resistant aluminum rigid pipe for automotive air conditioning, including a U-shaped pipe section 1 and a straight pipe section 2. Both ends of the U-shaped pipe section 1 are welded and fixed with straight pipe sections 2. A fixing seat 3 is fixedly connected to the bottom of the U-shaped pipe section 1. A clamping member 4 is fixedly connected at the connection between the straight pipe section 2 and the U-shaped pipe section 1. The fixing seat 3 and the clamping member 4 are fixedly connected.

[0030] Both ends of the U-shaped pipe section 1 are equipped with insertion parts 5, which are inserted into the straight pipe section 2 and then welded in place. After the insertion parts 5 are inserted into the straight pipe section 2, they are then welded to form a double-sealed structure. This increases the contact surface between the U-shaped pipe section 1 and the straight pipe section 2, improving the connection strength and sealing performance. Both the U-shaped pipe section 1 and the straight pipe section 2 are made of aluminum, which provides high strength and corrosion resistance.

[0031] A splicing seat 6 is fixedly connected to the fixed seat 3, and the U-shaped pipe section 1 is clamped between the fixed seat 3 and the splicing seat 6. By splicing the upper and lower parts, the fixed seat 3 and the splicing seat 6 form a 360° wrap-around fixation, distributing the force on the U-shaped pipe section 1 to the entire support surface, and preventing metal fatigue cracks in the U-shaped pipe section 1 due to long-term vibration.

[0032] The top surface of the fixing base 3 is provided with an arc-shaped groove 7, which matches the bottom of the U-shaped pipe section 1. The bottom of the splicing base 6 is provided with a splicing groove 8, which matches the top of the U-shaped pipe section 1. After the fixing base 3 and the splicing base 6 are fixed, the arc-shaped groove 7 and the splicing groove 8 connect to form a limiting groove 9, which limits the U-shaped pipe section 1 within the limiting groove 9. The arc-shaped groove 7 increases the contact area and eliminates the phenomenon of local stress concentration in the U-shaped pipe section 1.

[0033] The top of the fixing base 3 is evenly distributed with connecting screws 10. The top of the connecting screws 10 passes through the splicing base 6, and the top of the connecting screws 10 is screwed into the connecting nut 11. The connecting nut 11 is tightened on the splicing base 6. The setting of the connecting screws 10 and the connecting nut 11 facilitates the assembly and disassembly of the fixing base 3 and the splicing base 6.

[0034] The clamping component 4 includes an upper clamping seat 12 and a lower clamping seat 13. The top of the lower clamping seat 13 is provided with a first groove 14, and the bottom of the connection between the U-shaped pipe section 1 and the straight pipe section 2 rests in the first groove 14. The bottom of the upper clamping seat 12 is provided with a second groove 15, and the top of the connection between the U-shaped pipe section 1 and the straight pipe section 2 rests in the second groove 15. After being fixed by the upper clamping seat 12 and the lower clamping seat 13, the connection between the U-shaped pipe section 1 and the straight pipe section 2 is clamped and fixed, increasing the stability of the connection between the U-shaped pipe section 1 and the straight pipe section 2.

[0035] Both sides of the top of the lower clamping seat 13 are provided with connecting screws 16. The top of the connecting screws 16 passes through the upper clamping seat 12, and a connecting nut 17 is screwed into the top of the connecting screws 16. The connecting nut is tightened onto the upper clamping seat 12. Through the cooperation of the connecting screws 16 and the connecting nuts 17, the lower clamping seat 13 and the upper clamping seat 12 are fixedly connected, while facilitating the assembly and disassembly of the upper clamping seat 12 and the lower clamping seat 13.

[0036] The fixed base 3 is fixedly connected to an adjusting rod 18. The bottom of the lower clamping base 13 has a corresponding through hole 19 through which the adjusting rod 18 passes. The adjusting rod 18 is provided with a limiting member, which limits and fixes the lower clamping base 13 on the adjusting rod 18. The adjusting rod 18 can be set to adjust the clamping member 4 according to the position of the connection between the U-shaped pipe section 1 and the straight pipe section 2.

[0037] The limiting component includes two adjusting seats 20, which are slidably connected to the adjusting rod 18. A lower clamping seat 13 is located between the two adjusting seats 20. One end of each adjusting seat 20 has a tightening end 21 that abuts against the lower clamping seat 13. The other end of each adjusting seat 20 has a tightening screw 22. When the lower clamping seat 13 is limited to the adjusting rod 18, the tightening screw 22 tightens against the adjusting rod 18. The tightening screw 22 is used to fix the adjusting seat 20 to the adjusting rod 18. The two adjusting seats 20 drive the lower clamping seat 13 to slide and adjust. After adjustment, the adjusting seats 20 and the adjusting rod 18 are fixedly connected by the tightening screw 22, thereby limiting the position of the lower clamping seat 13.

[0038] A limiting block 23 is fixedly connected to the end of the adjusting rod 18. The limiting block 23 serves to limit the lower clamping seat 13 and the adjusting seat 20, preventing them from slipping off the adjusting rod 18.

[0039] This invention fixes a U-shaped pipe section 1 and a straight pipe section 2 by welding them together. A fixing seat 3 is then installed at the bottom of the U-shaped pipe section 1, and a clamping member 4 is fixed at the weld joint. The clamping member 4 is connected to the fixing seat 3. The synergistic effect of the bottom fixing seat 3 and the clamping member 4 at the connection point gives the pipeline excellent vibration resistance and structural stability. The fixing seat 3 effectively absorbs the impact load during pipeline operation, while the clamping member 4 prevents deformation at the connection point due to stress concentration, thereby greatly extending the service life of the pipeline.
