[0002] Nitrogen generator is a kind of equipment suitable for laboratories, pharmaceuticals, food, medical and other fields, which can extract high-purity nitrogen from the air. The working principle of nitrogen generator is to remove moisture, carbon dioxide, grease and other impurities in the air through molecular sieve adsorption technology, and then produce purified nitrogen through multiple processes such as compression, filtration, membrane separation, etc. The compression module in the nitrogen generator is used to compress the gas in the atmosphere so that it can enter the subsequent membrane module for processing. The compression module uses an air compressor. When the air compressor is working, it will generate vibration, so shock-absorbing pads are needed to reduce shock.

[0003] In the related art, the shock-absorbing pad structure of the air compressor used in the nitrogen generator is not strong enough to support the shock-absorbing pad rubber directly to the bottom when the air compressor is working, which increases the vibration when the air compressor is working.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0036] The utility model provides a shock-absorbing pad.

[0037] In the embodiment of the present utility model, Figure 1 As shown, the shock-absorbing pad comprises a shock-absorbing pad body 1 and two connecting screws 2, wherein the shock-absorbing pad body 1 is an annular structure having a hollow hole 11; each of the connecting screws 2 is respectively connected to the shock-absorbing pad body 1 and extends out of the circumference of the shock-absorbing pad body 1; the two connecting screws 2 are coaxially arranged and symmetrically distributed on the circumference of the shock-absorbing pad body 1.

[0038] It is understandable that the load (air compressor) is connected by the connecting screw 2 to install the load on the shock-absorbing pad. When the load is working, the vibration is transmitted to the shock-absorbing pad body 1 through the connecting screw 2. Since the shock-absorbing pad body 1 is an annular structure, two arc arms are formed between the two connecting screws 2, and the vibration will be dispersed to the arc arms. At the same time, the hollow hole 11 can also better buffer and support the load to achieve a shock-absorbing effect. The utility model optimizes the shock-absorbing pad from a structural point of view and improves the shock-absorbing effect. Furthermore, after the utility model improves the support strength, when the air compressor vibrates during operation, the upper and lower sides of the shock-absorbing pad body 1 will not touch each other, which effectively reduces noise and has a good shockproof effect.

[0039] In one embodiment of the present invention, Figure 1 As shown, the axial direction of the connecting screw 2 is perpendicular to the axial direction of the shock absorbing pad body 1. With such a design, the force transmitted from the connecting screw 2 to the shock absorbing pad body 1 can be dispersed more evenly, and the shock absorbing pad body 1 can withstand a greater force from the connecting screw 2, thereby improving the shock absorbing performance.

[0040] In order to further improve the support strength of the shock absorbing pad body 1 and improve the shock absorbing effect, in one embodiment of the utility model, the shock absorbing pad body 1 is annular. The arc design plus the hollow hole 11 design can better reduce the noise generated by the vibration of the air compressor and achieve a shock absorbing effect.

[0041] In one embodiment of the present invention, Figure 1 As shown, the number of the hollow hole 11 is one, and the hollow hole 11 is located in the middle of the shock absorbing pad body 1; the hollow hole 11 penetrates the shock absorbing pad body 1 along the axial direction of the shock absorbing pad body 1. It can be understood that the hollow hole 11 is designed in the middle and penetrates axially, so that the shock absorbing pad body 1 can evenly diffuse the force when it is subjected to force, thereby improving the shock absorption effect.

[0042] In one embodiment of the present invention, Figure 1 As shown, the shock-absorbing pad body 1 is further provided with a connecting boss 12 , and the connecting boss 12 is sleeved on the connecting screw 2 .

[0043] It can be understood that the connection stability and connection strength between the connecting screw 2 and the shock-absorbing pad body 1 can be improved by providing the connecting boss 12, thereby improving the shock-absorbing effect of the shock-absorbing pad.

[0044] In one embodiment of the present invention, Figure 1 As shown, the side of the connecting boss 12 facing away from the shock absorbing pad body 1 is a plane.

[0045] It can be understood that the side of the connecting boss 12 facing away from the shock-absorbing pad body 1 is designed to be a plane, which can facilitate the stable installation of the gasket 3.

[0046] In the prior art, the hardware and rubber of the shock-absorbing pad product are not integrally injection molded, which is inconvenient in installation and use. The hardware must be installed on the rubber, resulting in low efficiency in production and assembly. In one embodiment of the utility model, the connecting boss 12 and the shock-absorbing pad body 1 are an integrally connected structure. The material of the shock-absorbing pad body 1 is rubber, and the material of the connecting boss 12 is also rubber. The connecting screw 2 is a common standard product. In this embodiment, the shock-absorbing pad body 1 and the connecting screw 2 are integrally injection molded.

[0047] It is understandable that this embodiment is integrally formed by injection molding, and the connecting screw 2 is directly buried in the mold during the injection molding stage, which has more prominent economic benefits in mass production, reduces costs, and can be well promoted to industrial use. Due to the integral molding, the installation is also greatly shortened and the actual production efficiency is improved.

[0048] In one embodiment of the present invention, Figure 1 As shown, the shock-absorbing pad also includes a gasket 3, and the outer circumference of each connecting screw 2 is respectively sleeved with the gasket 3.

[0049] It can be understood that the gasket 3 can play a protective role.

[0050] When the connecting screw rod 2 of the shock-absorbing pad is connected to the load, the gasket 3 can prevent contact between the load and the shock-absorbing pad body 1 (in this embodiment, the gasket 3 can be placed on the plane of the connecting boss 12), thereby protecting the surface of the load and the shock-absorbing pad body 1.

[0051] like Figure 1 As shown, the shock-absorbing pad also includes a nut 4, and each of the connecting screws 2 is connected to a corresponding nut 4. The shock-absorbing pad and the load are locked by the nut 4. At the same time, a gasket 3 can also be arranged between the shock-absorbing pad and the load to play a protective role, prevent the surface of the load from being scratched by the nut 4, and disperse the pressure from the nut 4.

[0052] The utility model also proposes a nitrogen generator, which includes a nitrogen generator body, an air compressor and the shock-absorbing pad as described above. The specific structure of the shock-absorbing pad refers to the above embodiment. Since the nitrogen generator adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. The nitrogen generator body is connected to one of the connecting screws 2, and the air compressor is connected to another of the connecting screws 2.

[0053] Specifically, the base of the air compressor is provided with a connecting piece, and the box body of the nitrogen generator body is provided with a supporting plate. The connecting piece and the supporting plate are respectively connected to two connecting screws 2, and then are respectively locked by nuts 4 to achieve the purpose of installing the shock-absorbing pad.

[0054] It should be noted that the air compressor described in the present invention is an air compressor.

[0055] The above description is only an optional embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the creative concept of the utility model, or direct / indirect application in other related technical fields are included in the patent protection scope of the utility model.
