Description

Technical Field

[0001] The utility model relates to the technical field of air pressure switch gaskets, and more particularly to an air pressure switch gasket that is not easily deformed. Background Art

[0002] The gasket of the air pressure switch is a key component in the air pressure switch. It mainly plays the role of sealing and buffering. Through the elastic deformation of the gasket, it fits tightly with the adjacent components to prevent the leakage of gas, liquid or solid particles, and ensure the stability of the air pressure inside the air pressure switch. During the operation of the air pressure switch, the gasket can absorb and relieve shock and vibration, protect the internal parts of the switch from damage, and make the switch operation more stable and reliable.

[0003] Conventional gaskets for air pressure switches are typically made of a rubber material with a certain degree of elastic deformation. When subjected to high compressive stress, the gasket deforms significantly. This helps fill irregularities in the flange sealing surface and reduce the possibility of interfacial leakage. However, excessive compressive stress can crush the gasket, resulting in loss of sealing and impacting its resilience. If the gasket is subjected to excessive compressive stress for a long time, it can easily fatigue and become unable to reset. This can compromise the air tightness of the pressure switch and affect its proper operation. Therefore, we propose a gasket for air pressure switches that is less susceptible to deformation. Utility Model Content

[0004] The purpose of the present utility model is to overcome the shortcomings of the existing technology, adapt to actual needs, and provide a pressure switch gasket that is not easy to deform, so as to solve the technical problem that the current pressure switch gasket is exposed to excessive pressure stress for a long time, which easily leads to elastic fatigue and inability to reset, thereby reducing the air tightness of the pressure switch and affecting the normal use of the pressure switch.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a non-deformable air pressure switch gasket, comprising a gasket body with a mounting hole formed in the center thereof;

[0006] The interior of the mounting hole is symmetrically and fixedly mounted with elastic components;

[0007] The elastic assembly includes an elastic abutment ring centrally arranged in the mounting hole, a conical spring fixedly mounted on the outer edge surface of the elastic abutment ring, one end of the conical spring away from the elastic abutment ring is fixedly connected to the inner wall of the mounting hole, the elastic abutment rings in the symmetrically arranged elastic assembly are fixedly connected, and the conical spring has a volute structure;

[0008] An annular inner supporting groove is formed inside the gasket body and located outside the mounting hole. An annular connecting groove for connecting the mounting hole and the annular inner supporting groove is formed in the middle.

[0009] The utility model designs the gasket body, the mounting hole, the elastic component, the annular inner supporting groove and the annular connecting groove. When the gasket body is used as the sealing member of the air pressure switch, when it is in an environment of excessive compressive stress for a long time, the conical vortex structure of the conical spring is conducive to dispersing the compressive stress, so that the gasket body bears the compressive stress relatively evenly. At the same time, the elastic force of the conical spring is conducive to assisting the gasket body to perform elastic reset, which is conducive to reducing the situation where the gasket of the air pressure switch is in an environment of excessive compressive stress for a long time, resulting in elastic fatigue and inability to reset.

[0010] Preferably, the inside of the annular inner support groove is provided with serpentine spring pieces in an annular array, the two ends of the serpentine spring pieces are respectively fixedly connected to the opposite corners of the inner wall of the annular inner support groove, and the middle part of the serpentine spring pieces forms an S-shaped structure.

[0011] Preferably, annular support grooves are formed inside the gasket body above and below the annular inner support groove. The annular support groove has a triangular structure in the cross-sectional direction, and V-shaped elastic sheets are arranged in an annular array inside the annular support groove.

[0012] Preferably, the V-shaped elastic sheet has a V-shaped structure, and both ends of the V-shaped elastic sheet are fixedly connected to both sides of the inner wall of the annular support groove, and the V-shaped elastic sheets arranged in the annular support groove are mirror-symmetrical to each other.

[0013] Preferably, an outer edge surface of the gasket body is provided with ear-shaped portions in an annular array structure, and a fixing hole is centrally provided inside the ear-shaped portions.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The utility model designs the gasket body, the mounting hole, the elastic component, the annular inner support groove and the annular connecting groove. When the gasket body is used as the seal of the air pressure switch, when it is in an environment of excessive compressive stress for a long time, the conical vortex structure of the conical spring is conducive to dispersing the compressive stress, so that the gasket body bears the compressive stress relatively evenly. At the same time, the elastic force of the conical spring is conducive to assisting the gasket body to perform elastic reset, which is conducive to reducing the situation where the air pressure switch gasket is in an environment of excessive compressive stress for a long time, resulting in elastic fatigue and inability to reset. It solves the problem that the air pressure switch gasket is easily fatigued and unable to reset due to being in an environment of excessive compressive stress for a long time, which leads to reduced air tightness of the air pressure switch and affects the normal use of the air pressure switch.

[0016] 2. The present invention also symmetrically arranges the elastic components, so that the conical springs in the elastic components are arranged in mirror symmetry with each other. Through the symmetrically arranged elastic components, the compressive stress on the gasket body is dispersed at the top and bottom of the mounting hole, thereby balancing the force on both sides of the gasket body, which is beneficial to maintaining the stability of the gasket body when used in a compressive stress environment.

[0024] In an embodiment of the present invention, a serpentine spring piece 9 is arranged in an annular array inside the annular inner support groove 8, and the two ends of the serpentine spring piece 9 are respectively fixedly connected to the opposite corner positions of the inner wall of the annular inner support groove 8, and the middle part of the serpentine spring piece 9 forms an S-shaped structure. During the installation process of the gasket body 1, its two sides are subjected to compressive stress, which can cause the serpentine spring piece 9 to deform. At the same time, the serpentine spring piece 9 provides shape support inside the gasket body 1, thereby maintaining the shape of the gasket body 1.

[0025] In an embodiment of the present utility model, an annular support groove 6 is formed inside the gasket body 1 above and below the annular inner support groove 8. The annular support groove 6 has a triangular structure in the cross-sectional direction, and a V-shaped elastic sheet 7 is arranged in an annular array inside the annular support groove 6. The V-shaped elastic sheet 7 has a V-shaped structure, and both ends of the V-shaped elastic sheet 7 are fixedly connected to the inner wall of the annular support groove 6. Since both ends of the V-shaped elastic sheet 7 are fixedly connected to the inner wall of the annular support groove 6, the V-shaped elastic sheet 7 can form a triangular support structure inside the annular support groove 6, which is beneficial to provide stable support inside the gasket body 1 and maintain the shape of the gasket body 1.

[0026] Working principle: This embodiment provides a gasket for an air pressure switch that is not easily deformed. When the gasket body 1 is used as a seal for the air pressure switch, when it is in an environment with excessive compressive stress for a long time, the conical vortex structure of the conical spring 502 is conducive to dispersing the compressive stress, so that the gasket body 1 bears the compressive stress relatively evenly. At the same time, the elastic force of the conical spring 502 is conducive to assisting the gasket body 1 to perform elastic reset. By symmetrically arranging the elastic component 5, the conical springs 502 in the elastic component 5 are arranged in mirror symmetry with each other. The symmetrically arranged elastic component 5 disperses the compressive stress on the gasket body 1 at the top and bottom of the mounting hole 4, thereby balancing the force on both sides of the gasket body 1, which is beneficial to maintaining the stability of the gasket body 1 when used in a compressive stress environment. By arranging V-shaped elastic sheets 7 and snake-shaped spring sheets 9 in an annular array inside the annular support groove 6 and the annular inner support groove 8 respectively, the shape of the gasket body 1 is supported by the V-shaped elastic sheet 7, and the snake-shaped spring sheet 9 can further assist the gasket body 1 in elastic reset, thereby maintaining the shape of the gasket body 1 and making it not easily deformed.
