[0002] Automotive air conditioning is a device used to regulate the temperature, humidity, air cleanliness, and airflow inside a car. It aims to provide passengers with a comfortable riding environment, reduce travel fatigue, and create good working conditions for the driver to ensure driving safety. Automotive air conditioning pipes are specially designed pipes with good heat dissipation performance for air conditioners and refrigeration system heat exchangers. Their function is to deliver cool air inside the car to lower the interior temperature. To ensure the normal operation of automotive air conditioning, the sealing performance of automotive air conditioning pipes needs to be tested before they are put into use.

[0003] A search revealed that Chinese patent application CN21277978U discloses a detection device for leak detection of automotive air conditioning pipes. The device is miniaturized and easy to use, and can also detect air conditioning pipes of a certain length and hardness that are difficult to immerse in water, increasing the device's adaptability.

[0004] However, the following technical problems still exist when implementing the above technical solution: the above device can only clamp and test one tube at a time when in use, which is very inefficient and cannot meet the requirements of rapid testing.

[0005] Therefore, the problem that this utility model urgently needs to solve is to provide an automotive air conditioning pipe testing device that allows installation, disassembly, and airtightness testing to be performed simultaneously during use, which can greatly save testing time, increase testing speed, and allow for quick and intuitive observation of the airtightness of the air conditioning pipe. Utility Model Content

[0006] To address the aforementioned technical problems, the purpose of this utility model is to overcome the fact that in the existing technology, the equipment can only clamp and test one pipe at a time, which results in very low testing efficiency and cannot meet the requirements for rapid testing. Therefore, this utility model provides an automotive air conditioning pipe testing device that allows installation, disassembly, and airtightness testing to be performed simultaneously during use, and also allows for quick and intuitive observation of the airtightness of the air conditioning pipe.

[0007] To achieve the above objectives, this utility model provides an automotive air conditioning pipe testing device. The testing device includes: a placement box containing anhydrous copper sulfate powder; and a testing mechanism on the placement box that can rotate horizontally to sequentially test the sealing performance of multiple air conditioning pipes.

[0008] The testing mechanism includes: two sets of polygonal supports spaced apart and rotatable around the horizontal direction; each side of the supports is provided with a testing element for testing the sealing performance of the air conditioning pipe by injecting water and placing anhydrous copper sulfate powder in the box; and an adjustment component for clamping and fixing air conditioning pipes of different lengths.

[0009] Preferably, the detection mechanism further includes: a first mounting plate, a first sealing head, and a water supply pipe; wherein,

[0010] Two sets of brackets are rotatably connected to the placement box via rotating shafts. A first mounting plate is fixed on each side of one bracket, and a first sealing head for installing the air conditioning pipe is fixed on each first mounting plate. A water tank corresponding to the first sealing head is fixed on the bracket. The water tank is connected to the first sealing head via a water supply pipe. An inlet pipe connected to each water tank is rotatably connected to the bracket via a first bearing. A circulation component connected to the air conditioning pipe being tested is fixed on the other bracket.

[0011] Preferably, the circulation component includes: a water storage tank, an outlet pipe, and a circulation pipe; wherein,

[0012] The bracket is fixed with water storage tanks that correspond one-to-one with the water supply tanks. The water storage tanks are connected to the regulating component through the water outlet pipe, thereby communicating with the air conditioning pipe. Multiple water storage tanks are connected to the circulation pipe to discharge the stored liquid for recycling.

[0013] Preferably, the adjustment assembly includes: a second mounting plate, a spring, and a limiting rod; wherein,

[0014] Multiple sets of limiting rods are fixedly connected between the two sets of brackets at intervals. A second mounting plate is slidably sleeved on the two adjacent sets of limiting rods. A second sealing head connected to the air conditioning pipe is fixedly installed on the second mounting plate. The second sealing head is connected to the water storage tank through the water outlet pipe. Each set of limiting rods is sleeved with a spring at both ends that abuts against the side of the second mounting plate and the side of the bracket, respectively.

[0015] Preferably, the placement box is equipped with a rotating component that drives the support to rotate, thereby causing the air conditioning pipes mounted on the support to sequentially contact the anhydrous copper sulfate inside the placement box.

[0016] Preferably, the rotating assembly includes: a rotary motor, a transmission belt, and a second bearing; wherein,

[0019] Preferably, the placement box is fixedly provided with a control panel that is electrically connected to the rotating motor.

[0020] According to the above technical solution, the automotive air conditioning pipe testing device provided by this utility model has the following advantages in use: When the testing mechanism starts working, two sets of polygonal supports rotate horizontally. When an air conditioning pipe is rotated to the testing position, the testing component on the support begins to inject water into the air conditioning pipe. Simultaneously, the adjusting component clamps and fixes the air conditioning pipe to ensure that it does not move or deform during the testing process, thus affecting the accuracy of the test results. After water injection, observe whether the anhydrous copper sulfate powder in the storage box changes color. If the powder turns blue in a certain place, it indicates that there is a moisture leak at that point, meaning the corresponding air conditioning pipe is not properly sealed. The testing mechanism continues to rotate, and the same testing process is performed on the next air conditioning pipe.

[0029] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0030] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0031] Reference Figures 1-4 As shown, an automotive air conditioning pipe testing device includes: a placement box 100 containing anhydrous copper sulfate powder, and a testing mechanism 200 rotatable in the horizontal direction for sequentially testing the sealing performance of multiple air conditioning pipes.

[0032] The testing mechanism 200 includes: two sets of polygonal supports 201 arranged at intervals and rotatable around the horizontal direction. Each side of the support 201 is provided with a testing element for testing the sealing performance of the air conditioning pipe by injecting water and placing anhydrous copper sulfate powder in the box 100, and an adjustment component 300 for clamping and fixing air conditioning pipes of different lengths.

[0033] In use, anhydrous copper sulfate powder is placed in the placement box 100. The anhydrous copper sulfate powder turns blue when it comes into contact with moisture. Using anhydrous copper sulfate powder as the detection medium, the powder quickly changes color when there is a moisture leak, making the test results intuitive and reliable. The detection mechanism 200 begins operation, with two sets of polygonal supports 201 rotating horizontally. The design of these two sets of supports 201 allows them to sequentially perform sealing tests on multiple air conditioning pipes. When an air conditioning pipe is rotated to the detection position, the detection element on the support 201 begins to inject water into that pipe. The purpose of water injection is to simulate the pressure environment of the air conditioning pipe during actual operation to detect whether there is a leak. At the same time, the adjusting component 300 clamps and fixes the air conditioning pipe to ensure that the air conditioning pipe does not move or deform during the test, thus affecting the accuracy of the test results. After water injection, observe whether the anhydrous copper sulfate powder in the placement box 100 changes color. If the powder turns blue at a certain point, it indicates a moisture leak, meaning the corresponding air conditioning pipe is not sealed properly. The detection mechanism 200 continues to rotate, performing the same test procedure on the next air conditioning pipe.

[0034] Reference Figures 2-3 As shown, the detection mechanism 200 further includes: a first mounting plate 203, a first sealing head 204, and a water supply pipe 206; wherein,

[0035] Two sets of brackets 201 are rotatably connected to the placement box 100 via rotating shafts 202. A first mounting plate 203 is fixedly provided on each side of one bracket 201. A first sealing head 204 for installing air conditioning pipe is fixedly provided on each first mounting plate 203. A water tank 205 corresponding to the first sealing head 204 is fixedly provided on the bracket 201. The water tank 205 is connected to the first sealing head 204 via a water supply pipe 206. An inlet pipe 209 connected to each water tank 205 is rotatably connected to the bracket 201 via a first bearing 210. A circulation component connected to the air conditioning pipe being tested is fixedly provided on the other bracket 201.

[0036] In the above scheme, the air conditioning pipe to be tested is installed on the first sealing head 204, which ensures the seal between the air conditioning pipe and the testing device. Two sets of brackets 201 are rotatably connected to the placement box 100 via a rotating shaft 202, allowing the brackets 201 and the testing components on them to rotate horizontally. The inlet pipe 209 is connected to each water tank 205 via a first bearing 210, allowing water or other testing liquids to enter the water tank 205. The water tank 205 is connected to the first sealing head 204 via a water pipe 206, thereby injecting the testing liquid into the air conditioning pipe. The pressure inside the air conditioning pipe gradually increases, simulating actual working conditions. On the other side of the bracket 201, the water storage tank 207 is connected to the regulating component 300 via an outlet pipe 208, and thus connected to the air conditioning pipe, ready to receive the testing liquid flowing out of the air conditioning pipe. The anhydrous copper sulfate powder in the placement box 100 is observed to determine if there is a leak in the air conditioning pipe. Meanwhile, the detected liquid circulates within the air conditioning pipes and is recycled through the water storage tank 207, the water outlet pipe 208, and the circulation pipe 211.

[0037] Reference Figures 2-3 As shown, the circulation component includes: a water storage tank 207, a water outlet pipe 208, and a circulation pipe 211; wherein,

[0038] The bracket 201 is fixedly equipped with a water storage tank 207 corresponding to the water supply tank 205. The water storage tank 207 is connected to the regulating component 300 through the water outlet pipe 208 and thus connected to the air conditioning pipe. Multiple water storage tanks 207 are connected to the circulation pipe 211 to discharge the stored liquid for recycling.

[0039] In the above scheme, the test liquid enters the water tank 205 through the inlet pipe 209, and then is injected into the air conditioning pipe through the water supply pipe 206. The test liquid in the air conditioning pipe flows out under pressure and enters the storage tank 207 through the outlet pipe 208. Multiple storage tanks 207 are connected through the circulation pipe 211 to discharge the stored test liquid and recycle it. During the test, observe whether the anhydrous copper sulfate powder in the placement box 100 changes color and record the test results.

[0040] Reference Figures 2-4 As shown, the adjustment assembly 300 includes: a second mounting plate 301, a spring 302, and a limiting rod 303; wherein,

[0041] Multiple sets of limiting rods 303 are fixedly connected between two sets of brackets 201 at intervals. A second mounting plate 301 is slidably sleeved on two adjacent sets of limiting rods 303. A second sealing head 304 connected to the air conditioning pipe is fixedly installed on the second mounting plate 301. The second sealing head 304 is connected to the water storage tank 207 through the water outlet pipe 208. Each set of limiting rods 303 is sleeved with a spring 302 at both ends that abut against the side of the second mounting plate 301 and the side of the bracket 201, respectively.

[0042] In the above scheme, the air conditioning pipe to be tested is connected to the second mounting plate 301 via the second sealing head 304. The second sealing head 304 ensures the seal between the air conditioning pipe and the testing device. The second mounting plate 301 is slidably sleeved on two adjacent sets of limiting rods 303, allowing adjustment according to the length of the air conditioning pipe. A spring 302 is sleeved on each set of limiting rods 303, with its two ends abutting against the side of the second mounting plate 301 and the side of the bracket 201, respectively. The spring 302 provides appropriate pressure to ensure the stability of the second mounting plate 301 and the air conditioning pipe on it. The second sealing head 304 is connected to the water storage tank 207 via the water outlet pipe 208, ready to receive the test liquid flowing out of the air conditioning pipe. The test liquid is injected into the air conditioning pipe through the water supply pipe 206 to simulate actual working conditions, and then flows out and enters the water storage tank 207 through the water outlet pipe 208. The design of the adjustment component 300 allows for flexible adjustment of air conditioning pipes of different lengths, improving the versatility of the testing device.

[0043] Reference Figures 1-2 As shown, the placement box 100 is provided with a drive bracket 201 to rotate, thereby causing the air conditioning pipes installed on the bracket 201 to come into contact with the anhydrous copper sulfate in the placement box 100 in sequence.

[0044] In the above scheme, the rotating component 400 drives the bracket 201 to rotate around the horizontal direction, so that the air conditioning pipes mounted on the bracket 201 come into contact with the anhydrous copper sulfate powder in the placement box 100 in sequence. During the rotation, a detection liquid is injected into the air conditioning pipes to simulate actual working conditions.

[0045] Reference Figures 1-2 As shown, the rotating assembly 400 includes: a rotary motor 401, a transmission belt 402, and a second bearing 403; wherein,

[0046] A rotary motor 401 is fixedly installed on the placement box 100. The output shaft of the rotary motor 401 is horizontally arranged and connected to the rotating shaft 202 via a transmission belt 402. The transmission belt 402 rotates through the side wall of the placement box 100 via a second bearing 403.

[0047] In the above scheme, the rotary motor 401 is started, and the output shaft of the rotary motor 401 begins to rotate. The power is transmitted to the rotating shaft 202 through the transmission belt 402. The transmission belt 402 rotates through the side wall of the placement box 100 via the second bearing 403 to ensure the smoothness and reliability of the power transmission. After receiving the power, the rotating shaft 202 begins to rotate, driving the two sets of brackets 201 and their detection mechanisms 200 and air conditioning pipes to rotate around the horizontal direction. During the rotation, the air conditioning pipes come into contact with the anhydrous copper sulfate powder in the placement box 100 in turn to perform a sealing test.

[0048] Reference Figures 1-2 As shown, the bottom surface of the placement box 100 is provided with multiple sets of support legs 101 at fixed intervals.

[0049] In the above scheme, multiple sets of support legs 101 are fixedly spaced on the bottom surface of the placement box 100, providing stable support and ensuring that the testing device will not shake or tilt during the testing process.

[0050] Reference Figure 2 As shown, the placement box 100 is fixedly provided with a control panel 102 that is electrically connected to the rotary motor 401.

[0051] In the above scheme, before starting the rotary motor 401, the detection parameters are set through the control panel 102. During the detection process, the detection progress and results can be monitored in real time through the control panel 102. If it is necessary to adjust the detection parameters, they can be adjusted immediately through the control panel 102.

[0052] In summary, the automotive air conditioning pipe testing device provided by this utility model involves loading anhydrous copper sulfate powder into the placement box 100 during use. The position of the second mounting plate 301 on the limiting rod 303 is adjusted via the adjusting component 300 according to the length of the air conditioning pipe to be tested, ensuring that air conditioning pipes of different lengths can be securely clamped. The spring 302 provides the necessary pressure to ensure the seal between the second sealing head 304 and the air conditioning pipe, allowing the air conditioning pipe to be tested to be installed on the testing device. Specifically, one end of the air conditioning pipe is connected to the first sealing head 204, and the other end is connected to the second sealing head 304 via the adjusting component 300. When the device is started, the rotary motor 401 drives the rotating shaft 202 to rotate via the transmission belt 402, thereby rotating the bracket 201 and the testing components and air conditioning pipe on it. Water enters the water tank 205 corresponding to the first sealing head 204 through the water inlet pipe 209, and then is injected into the air conditioning pipe through the water delivery pipe 206. Meanwhile, the circulation component on the other side bracket 201 is in standby mode. After water is injected into the air conditioning pipe, if the air conditioning pipe is well sealed, the water will not leak to the outside. At this time, the bracket 201 continues to rotate, causing the air conditioning pipe to pass through the anhydrous copper sulfate powder in the placement box 100 in sequence. If there is a leak in the air conditioning pipe, the leaked water will come into contact with the anhydrous copper sulfate powder, causing the powder to change color, thus indicating the location of the leak. After the detection is completed, the water in the air conditioning pipe flows into the water storage tank 207 through the second sealing head 304 and the water outlet pipe 208. Multiple water storage tanks 207 are connected by circulation pipe 211 to realize the recycling of water. As needed, the water in the circulation pipe 211 can be discharged or treated periodically to avoid the accumulation of impurities or the deterioration of water quality. The operator observes the color change of the anhydrous copper sulfate powder in the placement box 100 and records which air conditioning pipes have leaks and the approximate location of the leaks.

However, the present invention is not limited to the specific details of the above embodiments.

[0054] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
