Description

Technical Field

[0001] The utility model relates to the technical field of connection structures, in particular to an integrated nitrogen spring connection structure. 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 final product. Therefore, it's often necessary to connect individual nitrogen springs to form a piping system to ensure consistent pressure across the springs. The pressure gauge on the gauge base can also be used to monitor the gas pressure during production. Nitrogen springs are typically connected via air pipes and connectors. This connection requires multiple sealing locations, making it prone to leaks. Installation also requires complete disassembly of the valve core, making installation more complex. Air pipes have limited compressive strength and carry a risk of bursting.

[0004] To this end, we proposed an integrated nitrogen spring connection structure to solve the problem. Utility Model Content

[0023] 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.

[0024] A preferred embodiment of the integrated nitrogen spring connection structure provided by the utility model is as follows Figure 1 to Figure 1 Figure 2 shows an integrated nitrogen spring connection structure, including:

[0025] Connecting plate 11;

[0026] Among them, a plug 14 is installed on the connecting plate 11, which is used to connect the various chambers through the opened air holes;

[0027] The base 12 has one end mounted on the connecting plate 11 by screws;

[0028] Among them, a second O-ring 13 is provided at the mounting position of the connecting plate 11 and the meter base 12, which is used to seal the air chamber connecting the connecting plate 11;

[0029] The guide sleeve 2 is fixedly mounted in the connecting plate 11 through the clamping block 4;

[0030] Among them, the outer dustproof 3, the supporting pad 5, and the first O-ring 6 are respectively installed between the guide sleeve 2 and the connecting plate 11. The inner dustproof 7, the guide ring 8, and the rod seal 9 are installed inside the guide sleeve 2. Here, the number of the guide rings 8 is two;

[0031] The plunger rod 1 is installed in the guide sleeve 2.

[0032] Working Principle: The integrated nitrogen spring connection structure primarily consists of a guide sleeve 2, a plunger rod 1, a connecting plate 11, and a gauge base 12. The plunger rod 1 is mounted within the guide sleeve 2, which is internally fitted with an internal dust shield 7, two guide rings 8, and a rod seal 9. The guide sleeve 2 is mounted within the connecting plate 11 and secured with a retaining ring 4. It also features an external dust shield 3, a support pad 5, and a first O-ring seal 6. A plug 14 is mounted on the connecting plate 11, connecting the various chambers via the perforated air holes. The gauge base 12 is screwed to the side of the connecting plate 11. A second O-ring 13 seals the bottom of the gauge base 12, connecting it to the connecting plate's air chamber.

[0033] To sum up: this structure does not have a traditional cylinder structure, and the guide sleeve is directly installed with the hole on the mounting plate to make it an integrated structure. In this way, the internal space can be larger, the initial force and the final force fluctuations are smaller, the elastic force will be more stable, and the elastic force will be more accurate. The various chambers are connected through the air holes on the connecting plate, and the positions that need to be sealed are reduced by half. From the perspective of the probability of air leakage, the risk of air leakage is reduced. The integrated structure is more solid, and the pressure resistance is much greater than that of traditional air pipes. There is no risk of cylinder explosion, which improves safety.

Any equivalent changes and modifications made by any technician in this field without departing from the concept and principle of the present invention should fall within the scope of protection of the present invention. It should also be noted that the various components of the present invention are not limited to the above-mentioned overall application. The various technical features described in the specification of the present invention can be selected for use alone or in combination according to actual needs.
