Description

Technical Field

[0001] The utility model relates to the technical field of adapters, in particular to a pressure regulating adapter. Background Art

[0002] Nitrogen gas springs are a new type of elastic component that uses high-pressure nitrogen as its working medium. Compared to traditional metal springs, nitrogen gas springs have an initial force, providing a relatively large reaction force at the initial compression position, and a relatively constant force throughout the entire stroke. They are compact and lightweight, while also achieving high elasticity. Nitrogen gas springs are widely used not only in the mold industry but also in other industrial fields such as automotive, electronics, and instrumentation. Therefore, nitrogen gas springs have a wide range of applications, and their emergence meets the needs of the times.

[0003] During the use of a single nitrogen spring, the gas pressure inside is unknown. This is especially true during stamping production, where excessive or insufficient pressure can significantly impact the resulting product. This often necessitates the connection of various sensors, piping systems, or pressure gauges to monitor the pressure during production and ensure product quality. During this connection, the valve core must be removed, the gas released, and then a connector connected and inflated to the desired pressure. This is generally not recommended for non-professionals, and consideration must be given to the customer's availability of specialized inflation equipment. To facilitate operation and improve safety, a converter adapter is needed that allows for connection, inflation, deflation, and pressure regulation of nitrogen springs without removing the valve core.

[0004] To this end, we proposed a pressure regulating conversion joint to solve the problem. Utility Model Content

[0022] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation methods of the present invention are now described with reference to the accompanying drawings.

[0023] A preferred embodiment of a pressure regulating conversion joint provided by the present utility model is as follows: Figures 1 to 2 Shown: A pressure regulating adapter, comprising:

[0024] Valve body 22;

[0025] The valve seat 23 is fixed to the valve body 22 by a first screw 19, a second screw 20, and a third screw 21. A second O-ring 17 is installed between the valve seat 23 and the valve body 22 via a second retaining ring 16.

[0026] Among them, the valve seat 23 is internally installed with a ejector pin 13, a spring 15 and a dynamic sealing O-ring 18, and the side of the valve seat 23 is installed with a relief valve 24 for adjusting the gas pressure;

[0027] The cylinder 11 is mounted on the valve body 22, and a sealing gasket 14 is provided at the mounting position of the cylinder 11 and the valve body 22. A valve core 12 for inflating and sealing gas is installed on the cylinder 11;

[0028] The guide sleeve 10 is installed with the cylinder 11 through the first clamping ring 2;

[0029] Among them, a retaining ring 3 and a first O-ring 4 are arranged between the guide sleeve 10 and the cylinder 11, and an external dustproof 1 and an internal dustproof 5 are arranged between the guide sleeve 10 and the cylinder 11 to isolate external impurities and dust. The inner hole of the guide sleeve 10 is installed with a guide ring 6 for guiding. There are two guide rings 6. The inner hole of the guide sleeve 10 is installed with a supporting cup 7 and a sealing rod 8. The supporting cup 7 and the sealing rod 8 are tightly arranged with a plunger rod 9. The supporting cup 7 and the sealing rod 8 are used to seal the gas to prevent gas leakage when the plunger rod 9 moves up and down.

[0030] Working principle: The nitrogen spring is mainly composed of a cylinder 11, a guide sleeve 10, and a plunger rod 9. The plunger rod 9 is installed in the guide sleeve 10, which is installed in the cylinder 11. A valve core 12 is installed on the cylinder 11 for inflating and sealing the gas. The guide 10 and the cylinder 11 are installed with a first retaining ring 2, and the gas is sealed with a retaining ring 3 and a first O-ring 4. The external dustproof 1 and the internal dustproof 5 are used to isolate external impurities and dust. The guide sleeve 10 cooperates with the plunger rod 9, and two guide rings 6 are installed in the inner hole of the guide sleeve 10 for guiding. The inner hole of the guide sleeve 10 is equipped with a support ring 7 and a rod seal 8 that closely cooperates with the plunger rod 9 to seal the gas and prevent gas leakage when the plunger rod 9 moves up and down. The adapter consists of a valve body 22 and a valve seat 23 secured by a retaining ring. A second O-ring 17 and a screw are installed inside the valve seat 23 for dynamic sealing. A pin 13, a spring 15, and a dynamic seal O-ring 18 are installed inside the valve seat 23. A bleed valve 24 is mounted on the side of the valve seat 23 to adjust gas pressure. The screw pushes the pin 13, pushing open the valve core 12. Gas flows through the valve core 12 into the valve seat 23, then out of the valve body 22 and connects to a sensor, pressure gauge, or connecting pipe, thereby monitoring the internal pressure of the spring.

[0031] In summary, the structure of the present invention is simple to process and has high processing feasibility, a firm and durable structure, improved safety in use, and the gas pressure of the nitrogen spring is monitored, thereby improving product quality.
