Description

Technical Field

[0001] This utility model relates to the field of shock absorber inflation technology, and in particular to a shock absorber cylinder inflation device. Background Technology

[0002] A shock absorber is a device used to absorb and mitigate vibrations, commonly used in various mechanical systems to reduce damage or discomfort caused by vibrations. Its main function is to reduce the impact on equipment, occupants, or structures by absorbing and dissipating the energy of mechanical vibrations or impacts. The purpose of inflating the shock absorber cylinder is to regulate the air pressure, thereby controlling the shock absorber's performance.

[0003] After exploration and analysis, the following drawbacks were found in actual use:

[0004] During use, the shock absorber cannot be fixed in the center, which will cause the shock absorber to shift or tilt during inflation, increasing the error during inflation. At the same time, it cannot be adapted to shock absorbers of different specifications and sizes, and its application range is narrow.

[0005] In summary, this application proposes a shock absorber cylinder inflation device to solve the aforementioned problems. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution: a shock absorber cylinder inflation device, comprising:

[0008] The base has a top plate on top.

[0009] The limiting component is set on the base. The limiting component includes a movable plate, a square groove, a threaded rod and a limiting plate. There are two sets of movable plates and they are symmetrically distributed. A square groove is opened on the front side of the movable plate.

[0011] Preferably, the top of the base is fixedly installed with four sets of columns arranged in a rectangular array. Each column has a threaded post fixedly installed on its top. The top plate is fitted onto the threaded post, and bolts are threaded onto the columns. The bolts are located below the top plate, which facilitates the adjustment of the height of the top plate.

[0012] Preferably, a cylinder is fixedly installed on the top of the top plate, and an inflation pipe is fixedly installed on the free end of the cylinder through the top plate.

[0013] Preferably, the limiting component further includes a fixed base and a driving device. The bottom of the fixed base is fixedly installed with the top of the base, and the driving device is located inside the fixed base. The driving device drives two sets of moving plates to move relative to each other, which can accurately center and fix the shock absorber, ensuring that the shock absorber maintains a stable position during inflation. This can prevent the shock absorber from shifting or tilting, reduce errors during inflation, improve the uniformity and accuracy of inflation, and ensure that the pressure inside the cylinder reaches the expected standard. At the same time, it has good adaptability and can be adapted to shock absorbers of different specifications and sizes, so that the device can maintain high accuracy and stability during the inflation of various types of shock absorbers, and has strong adaptability.

The safety valve is an important safety protection component in the inflation device. When the pressure of the horizontal tube reaches the preset maximum value, the safety valve will automatically open to release excess gas, thereby preventing damage to the equipment or safety accidents caused by excessive air pressure.

The top plate 2 is fitted onto the threaded column 4. Bolts are threaded onto the columns 3 and are located below the top plate 2. This arrangement facilitates the adjustment of the height of the top plate 2.

[0027] Furthermore, a cylinder 5 is fixedly installed on the top of the top plate 2, and an inflation pipe 6 is fixedly installed through the free end of the cylinder 5 through the top plate 2.

[0028] Furthermore, the limiting assembly also includes a fixed base 7 and a driving device 8. The bottom of the fixed base 7 is fixedly installed to the top of the base 1. The driving device 8 is located inside the fixed base 7. The driving device 8 drives two sets of moving plates 9 to move relative to each other, placing the shock absorber on the fixed base 7. The height of the limiting plate 12 is adjusted according to the position of the shock absorber. The threaded rod 11 is rotated to move the limiting plate 12 on the threaded rod 11, and the driving device 8 is activated. Through the relative movement of the two sets of moving plates 9, the limiting plate 12 is driven by the moving plates 9 to clamp and fix the shock absorber in the center. This can accurately center and fix the shock absorber, ensuring that the shock absorber maintains a stable position during inflation. It can avoid the shock absorber's offset or tilt, reduce errors during inflation, improve the uniformity and accuracy of inflation, and ensure that the pressure in the cylinder reaches the expected standard. At the same time, it has good adaptability and can be adapted to shock absorbers of different specifications and sizes. This allows the device to maintain high accuracy and stability during the inflation of various types of shock absorbers, demonstrating strong adaptability.

[0029] Furthermore, a telescopic tube 13 is fixedly installed on the outer wall of the inflation tube 6 to facilitate the up-and-down movement of the inflation tube 6.

[0030] Secondly, the testing assembly also includes a fixing sleeve 15.

The top of the fixing sleeve 15 is fixedly installed to the bottom of the top plate 2. One end of the horizontal tube 14 is fixedly installed to the other end of the telescopic tube 13. A pressure sensor 16 monitors the gas pressure on the horizontal tube 14. If the gas pressure change in the horizontal tube 14 is within the range required for airtightness within the test time range, the airtightness is qualified. If the gas pressure change exceeds the range required for airtightness, the airtightness is unqualified. The pressure sensor 16 can monitor the air pressure changes of the horizontal tube 14 in real time. Through accurate detection of air pressure, the system can dynamically adjust during the inflation process to ensure that the inflation pressure is always maintained within the set range, avoiding inaccurate inflation due to excessively high or low pressure, which would affect the performance of the shock absorber. The safety valve 17 is an important safety protection component in the inflation device. When the pressure of the horizontal tube 14 reaches the preset maximum value, the safety valve 17 will automatically open to release excess gas, thereby preventing damage to the equipment or safety accidents caused by excessive air pressure.

The threaded rod 11 is rotated to move the limiting plate 12 on the threaded rod 11. The drive device 8 is started. The two sets of moving plates 9 move relative to each other. The moving plates 9 drive the limiting plate 12 to clamp and fix the shock absorber in the center. Then the cylinder 5 is started. The cylinder 5 drives the inflation pipe 6 to move downward so that the inflation pipe 6 contacts the top of the shock absorber. The gas is delivered to the inside of the telescopic pipe 13 through the horizontal pipe 14 by an external air pump. Then it is delivered to the inside of the inflation pipe 6 through the telescopic pipe 13. Finally, it is delivered to the inside of the shock absorber through the inflation pipe 6. After a certain pressure is reached, inflation is stopped. The pressure sensor 16 monitors the gas pressure on the horizontal pipe 14. If the change in air pressure on the horizontal pipe 14 is within the range of the airtightness requirement within the test time range, the airtightness is qualified. If the change in air pressure exceeds the range of the airtightness requirement, the airtightness is unqualified.
