[0002] The automotive air conditioning refrigerant receiver drier is an important component installed between the evaporator and condenser of the automotive air conditioning system. Its main function is to separate gaseous and liquid refrigerant, store excess liquid refrigerant, and remove excess moisture and impurities from the refrigeration system. The manufacturing process of the receiver drier is demanding, the structure is complex, the operating conditions are harsh, and the product is prone to failure.

[0003] In existing technologies, the bottom plate of the dryer bottle is often connected to the bottle body by welding or threading, and the outlet pipe is often connected to the bottom plate by threading. If the connection is not well sealed and refrigerant leaks, it will directly cause the cooling effect of the car air conditioning system to fail. Therefore, the dryer bottle needs to be tested for air tightness before production. Most existing air tightness testing benches only test the sealing of the dryer bottle in a static state. However, in actual use scenarios, the dryer bottle is in constant motion, which leads to a lack of test accuracy and necessitates improvement. Summary of the Invention

[0012] In summary, this utility model has the following beneficial effects:

[0013] 1. A U-shaped fixing block is rotatably connected to one side of the water tank to fix the mouth of the desiccant bottle, and a rotating abutting rod is set on the other side of the water tank based on the telescopic component to abut the bottom of the desiccant bottle. During installation, the mouth of the desiccant bottle is first inserted into the U-shaped positioning block. Then, the telescopic cylinder of the telescopic component drives the rotating abutting rod to extend and abut against the bottom of the desiccant bottle, so that the mouth of the desiccant bottle fits against the U-shaped fixing block. Subsequently, the synchronous drive component drives the U-shaped fixing block and the desiccant bottle to rotate synchronously. By setting a rotating sliding stage on the water tank and fixing a fixing block at the telescopic end of the telescopic cylinder, and setting a rotating ring on the rotating abutting rod, and opening a rotating groove on the fixing block for the rotating ring to rotate, the rotating abutting rod can maintain its position. While holding the contact point, it can also rotate synchronously with the U-shaped fixed block. When rotating, gas is input into the inflation tube through the gas supply component, and then passes through the third, second, and first air guide holes in sequence before being injected into the drying bottle through the inflation hole. This simulates the sealing performance of the drying bottle in motion. The structure is simple and the detection accuracy is high. At the same time, by setting a test block on the U-shaped fixed block and opening a test hole on the test block, and connecting the test hole and the first air guide hole through the air guide tube, when there is gas input in the first air guide hole, some gas will be discharged from the test hole through the air guide tube, thus avoiding the situation where no gas is discharged from the inflation hole and causing detection errors, ensuring the accuracy of the test structure.

Detailed Implementation

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Example:

[0022] Referring to Figures 1 to 5, a double-water-tank desiccant testing station includes a base 1 and water tanks 2 fixedly connected to the base 1. A drain pipe is provided at the bottom of the water tank 2, and a switch valve is fixedly connected to the drain pipe. The water in the water tank 2 is replaced periodically through the drain pipe 21. On one side of the water tank 2, a U-shaped fixing block 4 for fixing the mouth of the desiccant bottle is rotatably connected in parallel based on a synchronous drive assembly 3. A positioning insertion groove that mates with the mouth of the desiccant bottle is provided on the U-shaped fixing block 4. On the other side of the water tank 2, a rotating abutment rod 6 is rotatably connected based on a telescopic assembly 5 to abut against the bottom of the desiccant bottle so that the mouth of the desiccant bottle fits against the U-shaped fixing block 4. An inflation assembly 7 for inflating the desiccant bottle is provided inside the U-shaped fixing block 4.

[0023] Referring to Figures 2 and 3, specifically, the synchronous drive assembly 3 includes a rotating shaft 31 fixedly connected to the center of the U-shaped fixed block 4 and a rotating sleeve 32 fixedly connected to the side wall of the water tank 2. A first drive pulley 33 is coaxially fixedly connected to the end of the rotating shaft 31 away from the U-shaped fixed block 4. A drive motor 34 is fixedly connected to the base 1. A second drive pulley 35 is fixedly connected to the rotating shaft 31 of the drive motor 34. The first drive pulley 33 and the second drive pulley 35, as well as adjacent first drive pulleys 33, are all driven by a synchronous transmission belt 36. The second drive pulley 35 is driven to rotate by the drive motor 34, which in turn drives the first drive pulley 33 to rotate synchronously by the synchronous transmission belt 36, thereby driving the two sets of U-shaped fixed blocks 4 in the same water tank 2 to rotate synchronously.

[0024] Referring to Figures 1 and 5, specifically, the inflation assembly 7 includes an inflation hole 71 on the U-shaped fixing block 4 and a first air guide hole 72 coaxially located at the center of the rotating shaft 31. Several second air guide holes 73, communicating with the first air guide holes 72, are evenly distributed along the circumference of the inflation hole 71. A third air guide hole 74, cooperating with the second air guide holes 73, is provided on the rotating sleeve 32 for guiding air into the second air guide holes 73. An inflation pipe 75, communicating with the third air guide hole 74, is fixedly connected to the rotating sleeve 32. An air supply assembly 76, for supplying air to the inflation pipe 75, is fixedly connected to the base 1. When rotating, gas is input into the inflation pipe 75 through the air supply assembly 76, and sequentially passes through the third air guide hole 74, the second air guide hole 75, the third air guide hole 72, the second air guide hole 73, and the third air guide hole 74. After the air guide hole 73 and the first air guide hole 72, the gas is injected into the drying bottle through the inflation hole 71, thereby simulating the sealing performance of the drying bottle in motion. The structure is simple and the detection accuracy is high. The gas supply component 76 includes a high-pressure gas source 761 fixedly connected to the base 1 and a pressure regulating valve 762 connected to the high-pressure gas source 761. A gas distributor 763 is connected to the outside of the pressure regulating valve 762. The gas supply pipe is connected to the gas distributor 763. The inflation pipe 75 is equipped with a solenoid valve 764 for controlling the gas flow. The gas generated by the high-pressure gas source 761 is evenly divided into multiple streams through the gas distributor 763 and then enters the inflation pipe 75 and is then input to the inflation fixing block 54. The pressure of the gas is regulated by the pressure regulating valve 762. A test block 77 is fixedly connected to the U-shaped fixing block 4. The test block 77 has a test hole 78. The test hole 78 is connected to the first air guide hole 72 through the air guide tube 79. When there is gas input in the first air guide hole 72, some gas will be discharged from the test hole 78 through the air guide tube 79, thereby avoiding the situation where no gas is discharged from the inflation hole 71 and causing detection errors, thus ensuring the accuracy of the test structure.

[0025] Referring to Figures 1 and 4, specifically, the telescopic assembly 5 includes a fixed base 51 fixedly connected to the side wall of the water tank 2 and a telescopic cylinder 52 fixedly connected to the fixed base 51. A rotating sliding sleeve 53 for rotating and sliding the rotating abutment rod 6 is fixedly connected to the water tank 2. A fixed block 54 is fixedly connected to the telescopic end of the telescopic cylinder 52. A rotating ring 55 is coaxially protruding and fixedly connected to one end of the rotating abutment rod 6 near the telescopic cylinder 52. The fixed block 54 has a rotating groove 56 for rotating the rotating ring 55. By setting a rotating sliding platform on the water tank 2, fixing the fixed block 54 to the telescopic end of the telescopic cylinder 52, setting the rotating ring 55 on the rotating abutment rod 6, and opening the rotating groove 56 on the fixed block 54 for rotating the rotating ring 55, the rotating abutment rod 6 can rotate synchronously with the U-shaped fixed block 4 while maintaining contact.

[0026] Brief description of the usage process: First, insert the mouth of the dryer bottle into the U-shaped positioning block. Then, the telescopic cylinder 52 of the telescopic component 5 drives the rotating abutment rod 6 to extend and abut against the bottom of the dryer bottle, so that the mouth of the dryer bottle fits against the U-shaped fixing block 4. Then, the synchronous drive component 3 drives the U-shaped fixing block 4 and the dryer bottle to rotate synchronously. When rotating, the gas is input into the inflation pipe 75 through the gas supply component 76, and then passes through the third air guide hole 74, the second air guide hole 73 and the first air guide hole 72 in sequence, and then rushes into the dryer bottle through the inflation hole 71, thereby simulating the sealing of the dryer bottle in motion.
