[0002] O-rings are a common and fundamental component in sealing devices, playing a crucial role in balancing leakage and sealing. Widely used in hydraulic and pneumatic systems, their sealing performance directly impacts equipment safety. Currently, appropriate pressure testing devices are typically required to measure the sealing pressure of O-rings.

[0003] Existing O-ring sealing pressure testing devices can basically meet normal usage needs, but in a single pressure test, they can generally only test the pressure of a single O-ring mounted on the testing device, resulting in lower work efficiency. Therefore, this invention provides an O-ring sealing pressure testing device. Utility Model Content

A support plate is provided between the tops of the support air pipes. The support air pipes are provided with a check valve for preventing backflow and a pressure gauge for detecting the pressure inside the pipe.

[0007] The working panel is equipped with an air supply component for supplying air to the support air tube.

[0008] Furthermore, the pressure gauge is located above the check valve, and the support plate has several through holes that pass through the support air pipe. The through holes are seamlessly welded and fixed to the top of the outer wall of the support air pipe.

[0009] Furthermore, the air supply assembly includes an air pump fixedly installed at the bottom of the working panel, the output end of the air pump is provided with an air outlet pipe, the port of the air outlet pipe is provided with a connected annular air pipe, and a diverter pipe passing through the working panel and connected between the top of the annular air pipe and the supporting air pipe is provided.

[0010] Furthermore, the top of the support plate is provided with a limiting rod located outside the support air pipe and passing through the lower pressure plate.

[0011] Furthermore, a pressure sensor for detecting downward pressure is provided between the telescopic rod end of the electric push rod and the bottom of the lower pressure plate.

[0012] Furthermore, the top of the working panel is provided with a controller located on one side of the support plate.

[0013] The beneficial effects of this utility model are:

[0014] Through the combined action of the pressure-down assembly, air supply assembly, several supporting air pipes, check valve, and pressure gauge, compared to the traditional method of pressure testing a single O-ring installed on the upper testing equipment, it can simultaneously pressure test at least one O-ring. This is suitable for rapid quality inspection scenarios in the mass production of O-rings, improving work efficiency. Attached Figure Description

It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0023] According to the appendix Figure 1 , 3 As shown in Figure 4: This utility model provides an O-ring sealing pressure testing device, including a working panel 1, and supporting air pipes 2 fixedly installed on both sides of the top of the working panel 1. A supporting plate 3 is provided between the top of the supporting air pipes 2. The supporting air pipes 2 are equipped with a check valve 4 for preventing backflow and a pressure gauge 5 for detecting the pressure inside the pipe. The pressure gauge 5 is located above the check valve 4. The working panel 1 is equipped with an air supply assembly 9 for supplying air to the supporting air pipes 2. The air supply assembly 9 includes an air pump 10 fixedly installed at the bottom of the working panel 1. The output end of the air pump 10 is provided with an air outlet pipe 11, and the port of the air outlet pipe 11 is provided with a connected annular air pipe 12. The top of the annular air pipe 12 and the support air pipe 2 are provided with a diversion pipe 13 that passes through the working panel 1 and is connected. Specifically, the air pump 10 of the air supply assembly 9 generates compressed gas, which is diverted to each support air pipe 2 through the air outlet pipe 11, the annular air pipe 12, and the diversion pipe 13. The check valve on the support air pipe 2 can prevent the gas from flowing back after pressurization. The pressure gauge monitors the pressure value in the pipe in real time to determine whether there is a leak.

[0024] As per the instruction manual Figure 2 , 3As shown in Figure 4: The support plate 3 has several through holes passing through the support air pipe 2. The through holes are seamlessly welded and fixed to the top of the outer wall of the support air pipe 2. The support air pipe 2 is closed at the bottom and open at the top. The connection between the air pipes is sealed. The sealing treatment can be obtained by those skilled in the art based on basic common sense, in order to prevent air leakage in other places from affecting the sealing pressure detection effect of the O-ring. The lowering component 6 includes an electric push rod 7 fixedly set at the bottom center of the support plate 3. The telescopic rod end of the electric push rod 7 is provided with a lowering plate 8 located above the support plate 3. The top of the support plate 3 is provided with a limiting rod 14 located outside the support air pipe 2 and passing through the lowering plate 8, which serves as a limiting function. A pressure sensor 15 for detecting the lower pressure is provided between the telescopic rod end of the electric push rod 7 and the bottom of the lowering plate 8. Specifically, dynamic compression is performed. The electric push rod 7 drives the lowering plate 8 to move vertically. Combined with the guiding function of the limiting rod, the lowering trajectory is ensured to be accurate. The pressure sensor provides real-time feedback of the lower pressure data, realizing closed-loop control of the O-ring compression amount.

[0025] As per the instruction manual Figure 1 As shown: The top of the working panel 1 is equipped with a controller 16 placed on one side of the support plate 3. The controller, together with the pressure sensor, electric push rod, and air pump, realizes automated detection. The connection method and structure of the controller 16 with the pressure sensor, electric push rod, air pump, etc. can be obtained from the basic principles of circuits and are conventional technical means in this field. The internal circuit structure will not be described in detail here. The control method of this utility model is through the controller. The controller adopts existing known mature technology, which will not be described in detail here. The control circuit of the controller can be implemented by those skilled in the art through simple programming. The power supply is also common knowledge in this field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail here.

[0026] The principle of this utility model

[0027] During use, each O-ring needs to be placed in the working area below the support plate 3 and outside the corresponding support air pipe 2. The electric push rod 7 drives the lower pressure plate 8 to move vertically to press the O-ring against the top of the support plate 3. With the help of a pressure sensor, the pressure data is fed back in real time to realize closed-loop control of the O-ring compression. This can simulate the pre-compression state of the seal during assembly, verify its deformation recovery ability and the uniformity of the sealing contact surface. The air pump 10 generates compressed gas and distributes it to each support air pipe 2. The check valve on the support air pipe 2 can prevent the gas from flowing back after pressurization. The pressure gauge monitors the pressure value in the pipe in real time to determine whether there is a leak. The entire process of pressing-supplying-monitoring can be completed automatically. Compared with the traditional method of pressure testing a single O-ring installed on the upper testing equipment, it can pressure test at least one O-ring at the same time. It is suitable for rapid quality inspection scenarios in the mass production of O-rings and improves work efficiency.

[0028] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
