Description

Technical Field

[0001] This utility model relates to the field of air tank testing technology, and in particular to a pressure resistance and sealing test device for automotive air tanks. Background Technology

[0002] Existing gas cylinder sealing pressure resistance testing devices use clamping components to fix the gas cylinder in order to reduce the influence of the external environment on the test, ensuring that the gas cylinder does not shake and reducing the impact of gas cylinder shaking, making it easy to observe the location of the fins. However, when the gas cylinder gap is small or the gas is facing downwards, the gas inside the gas cylinder is not easy to escape, making it difficult to observe the gas cylinder's sealing performance through air bubbles. For example, the mobile gas cylinder sealing detection device disclosed in Chinese patent application number CN202121539958.X uses elastic support components and clamping components to rigidly fix the gas cylinder, which can ensure that the gas cylinder does not sway during the test, reduce disturbance to the water flow, and make it easy to observe the location of air bubbles. However, when the gas cylinder gap is small or the leak point is facing downwards, the gas inside the gas cylinder is not easy to escape, making it difficult to observe the gas cylinder's sealing performance. Summary of the Invention

[0003] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a pressure resistance and sealing test device for automotive air tanks. This device can activate a telescopic rod to extend a pressure plate, and an exhaust port is provided inside the pressure plate. When the pressure plate approaches the water surface inside the storage tank, air below the pressure plate can be discharged through the exhaust port. When the air is completely discharged, a support plate abuts against the bottom of the storage tank, causing the piston rod to slide inside the exhaust port, thereby blocking the exhaust port. This allows the pressure plate to compress the water inside the storage tank, increasing the water pressure on the air tank. The cylinder undergoes pressure resistance and sealing tests simultaneously, preventing situations where leaks are too small or located below the cylinder, making it difficult for gas to escape. It also prevents damage to the device from cylinder bursting if it is of substandard quality. The extension rod controls the raising and lowering of the pressure plate, which in turn moves the piston rod and its bottom support plate, thus moving the cylinder in and out of the water tank. A slot is provided in the middle to facilitate water discharge after the cylinder is taken out of the water tank. The support plate is tilted downwards towards the slot, and the slider facilitates the loading and unloading of the cylinder.

[0004] This utility model also provides a pressure resistance and sealing test device for an automotive air tank, comprising: a water tank, a drain pipe connected to the side surface of the water tank, a bracket fixedly connected to the upper surface of the water tank, a telescopic rod fixedly connected to the upper surface of the bracket, a pressure plate fixedly connected to the output end of the telescopic rod, an exhaust hole opened inside the pressure plate, and a sealing ring fixedly connected to the side surface of the pressure plate; a support plate, a groove opened inside the support plate, a clamping block slidably connected inside the groove, a piston rod fixedly connected to the upper surface of the support plate, and a spring fixedly connected to the upper surface of the piston rod. The above components enable the telescopic rod to extend the pressure plate. An vent is located inside the pressure plate. When the pressure plate approaches the water surface in the storage tank, air below the pressure plate is expelled through the vent. After all air is expelled, the support plate presses against the bottom of the storage tank, causing the piston rod to slide inside the vent, thus blocking it. This allows the pressure plate to compress the water in the storage tank, increasing water pressure and simultaneously conducting pressure and sealing tests on the air cylinder. It also prevents leaks caused by small leak points or leaks located below the air cylinder, making it difficult for gas to escape. Furthermore, it prevents damage to the device from air cylinder bursting if it is of substandard quality. The telescopic rod controls the raising and lowering of the pressure plate, which in turn raises and lowers the piston rod and its bottom support plate, thus moving the air cylinder in and out of the storage tank. A slot is provided in the middle to facilitate water drainage after the air cylinder is removed from the storage tank. The support plate is tilted downwards towards the slot, and a slider facilitates the loading and unloading of the air cylinder.

[0005] According to the present invention, an automotive air reservoir pressure and sealing test device includes a valve installed inside the drain pipe, which is located at the bottom of the water storage tank. These components facilitate control over whether or not water should be drained from the water storage tank.

[0006] According to the present invention, an automotive air reservoir pressure resistance and sealing test device includes two telescopic rods located on both sides of a support, and a pressure plate positioned directly above the water storage tank. These components facilitate control of the pressure plate's raising and lowering, thereby pressurizing the water.

[0007] According to the present invention, an automotive air tank pressure resistance and sealing test device is provided, wherein the sealing ring matches the inner wall of the water tank, and the vent holes are four in number and located at the four corners of the pressure plate. These components prevent water from leaking out from the edges of the pressure plate when the pressure plate pressurizes the water inside the water tank.

[0008] According to the present invention, an automotive air reservoir pressure and sealing test device includes two inclined blocks fixedly connected to the upper surface of a support plate, located at both ends of the support plate. These components allow the air reservoir to naturally fall into the center of the support plate, making air reservoir installation more convenient.

[0009] According to the present invention, an automotive air reservoir pressure and sealing test device includes two clamping blocks located at both ends of a support plate, and four piston rods located at the four corners of the support plate. These components facilitate clamping of the air reservoir, preventing it from shaking or shifting, which could affect the test.

[0010] According to the present invention, an automotive air reservoir pressure and sealing test device is provided, wherein the end of the spring away from the piston rod is fixedly connected to the inside of the pressure plate, and the top end of the piston rod is slidably connected to the inner side wall of the pressure plate. With these components, after the support plate is removed from the water tank, the piston rod can automatically reset, making it easier to remove the air reservoir.

[0011] According to the present invention, an automotive air reservoir pressure resistance and sealing test device is provided, wherein the piston rod is located inside the exhaust hole, so that the piston rod can block the exhaust hole and the pressure plate can pressurize the water. Beneficial effects

[0012] Compared with the prior art, this utility model can activate the telescopic rod to push out the pressure plate, and an exhaust hole is provided inside the pressure plate. When the pressure plate approaches the water surface inside the water storage tank, the air below the pressure plate can be discharged through the exhaust hole. When the air is completely discharged, the support plate abuts against the bottom of the water storage tank, causing the piston rod to slide inside the exhaust hole, thereby blocking the exhaust hole. This allows the pressure plate to squeeze the water inside the water storage tank, increasing the water pressure to conduct pressure resistance and sealing tests on the air storage cylinder. It can also prevent situations where the leakage part is too small or faces downwards from the air storage cylinder, making it difficult for gas to be discharged from the air storage cylinder. If the air storage cylinder is of substandard quality, it can also prevent the air storage cylinder from bursting and causing damage to the device. The telescopic rod can control the lifting and lowering of the pressure plate, thereby driving the piston rod and the support plate at its bottom to lift and lower, that is, driving the air storage cylinder in and out of the water storage tank. A slot is provided in the middle to facilitate the discharge of water from the slot after the air storage cylinder is taken out of the water storage tank. The support plate is tilted downwards towards the slot, and the slider facilitates the loading and unloading of the air storage cylinder. Attached Figure Description

[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] Reference Figure 1-4 This utility model provides a pressure resistance and sealing test device for an automotive air tank, comprising: a water tank 1, a drain pipe 2 connected to the side surface of the water tank 1, a valve 13 installed inside the drain pipe 2, the drain pipe 2 being located at the bottom of the water tank 1, a bracket 3 fixedly connected to the upper surface of the water tank 1, two telescopic rods 4 fixedly connected to the upper surface of the bracket 3, the output end of the telescopic rod 4 being fixedly connected to a pressure plate 5, the pressure plate 5 being located directly above the water tank 1, four vent holes 6 being opened inside the pressure plate 5 and located at the four corners of the pressure plate 5, and a sealing ring 7 fixedly connected to the side surface of the pressure plate 5, the sealing ring 7 matching the inner wall of the water tank 1.

[0022] Specifically, by controlling valve 13, water inside the water storage tank 1 can be discharged through drain pipe 2. Activating telescopic rod 4 extends pressure plate 5, allowing air to be discharged from below pressure plate 5 through vent hole 6, so that the lower surface of pressure plate 5 can contact the water surface. With the help of sealing ring 7, water can only be discharged from vent hole 6, increasing the sealing performance of pressure plate 5. With the help of piston rod 11, pressure plate 5 can squeeze water, increasing the pressure on the water. At the same time, it completes the pressure resistance and sealing test of the air storage cylinder, preventing situations where the leakage point is too small or located below the air storage cylinder, making it difficult for gas to escape from the air storage cylinder. If the air storage cylinder is of substandard quality, it can also prevent the air storage cylinder from bursting and causing damage to the device.

[0023] A support plate 8 has two inclined blocks 14 fixedly connected to its upper surface. The inclined blocks 14 are located at both ends of the support plate 8. A slot 9 is opened inside the support plate 8. A clamping block 10 is slidably connected inside the slot 9. The clamping block 10 is located at both ends of the support plate 8. A piston rod 11 is fixedly connected to the upper surface of the support plate 8. There are four piston rods 11 located at the four corners of the support plate 8. The top of the piston rod 11 is slidably connected to the inner wall of the pressure plate 5. The piston rod 11 is located inside the exhaust hole 6. A spring 12 is fixedly connected to the upper surface of the piston rod 11. The end of the spring 12 away from the piston rod 11 is fixedly connected to the inside of the pressure plate 5.

[0024] Specifically, the tilting block 14 allows the air storage cylinder placed above it to fall directly above the empty trough 9, and the empty trough 9 can drain water when the air storage cylinder is removed. The sliding clamping block 10 can clamp the air storage cylinder from both sides to prevent the air storage cylinder from shaking and affecting the test results. A piston rod 11 is provided inside the exhaust hole 6 to seal the exhaust hole 6, so that the pressure plate 5 can pressurize the water normally. A spring 12 is provided to drive the piston rod 11 to reset when the air storage cylinder is removed, increasing the distance between the air storage cylinder and the pressure plate 5 to facilitate the removal of the air storage cylinder.

[0025] Working Principle: During operation, the water in the storage tank 1 can be drained through the drain pipe 2 by controlling valve 13. The telescopic rod 4 extends the pressure plate 5, allowing air to escape from below the pressure plate 5 through the vent 6. This ensures the lower surface of the pressure plate 5 contacts the water surface. Combined with the sealing ring 7, water can only exit through the vent 6, increasing the sealing performance of the pressure plate 5. The piston rod 11 further compresses the water, increasing the pressure on the water. Simultaneously, this completes the pressure resistance and sealing test of the air storage cylinder, preventing situations where the leakage point is too small or located at the bottom of the air storage cylinder, making it difficult for gas to escape. Even if the gas storage cylinder is of substandard quality, it can prevent the gas storage cylinder from bursting and causing damage to the device. The tilting block 14 allows the gas storage cylinder placed above it to fall directly above the empty trough 9. The empty trough 9 can drain water when the gas storage cylinder is removed. The sliding clamping block 10 can clamp the gas storage cylinder from both sides to prevent the gas storage cylinder from shaking and affecting the test results. A piston rod 11 is set inside the exhaust hole 6 to seal the exhaust hole 6, so that the pressure plate 5 can pressurize the water normally. A spring 12 is set to drive the piston rod 11 to reset when the gas storage cylinder is removed, increasing the distance between the gas storage cylinder and the pressure plate 5 to facilitate the removal of the gas storage cylinder.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
