Description

Technical Field

[0001] The utility model relates to a shockproof gasket, in particular to a shockproof gasket with a hollow structure, belonging to the technical field of shockproof structures. Background Art

[0002] The anti-vibration gasket is a fixed component that connects the fan and the client product. It is made of soft materials such as silicone. It is mainly used to buffer the resonance and other adverse phenomena brought to the terminal product when the fan is working. In the home appliance industry, the multi-point method is usually adopted when assembling the fan and the terminal product, that is, each fan is used with multiple anti-vibration gaskets. When designing the anti-vibration gasket, it is necessary to consider the large amount and good shock absorption effect.

[0003] At present, the anti-vibration gaskets of fans are generally made of rubber, elastic plastic and other materials. The gaskets are usually disc-shaped and have a certain thickness and elasticity to provide cushioning and shockproof effects. However, such disc-shaped anti-vibration gaskets are usually solid structures and heavy, which may increase the overall weight and burden of the fan, and do not have good air permeability, which may cause moisture accumulation during long-term use and affect the performance and life of the gasket. When installing the gasket, it is generally fixed by bolts or adhesives, which is inconvenient to install and use.

[0004] Therefore, we propose a hollow structure shock-absorbing gasket to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of the utility model is to provide a shock-proof gasket with a hollow structure.

[0020] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0021] like Figure 1-Figure 3 As shown, the hollow structure shockproof gasket provided in this embodiment includes a fixing claw 1 and a gasket body 3. The gasket body 3 can be made of a material with certain elasticity and buffering performance such as rubber, elastic plastic, etc. The fixing claw 1 is installed on the side wall of the patch body 2. According to actual use requirements, multiple fixing claws 1 can be set on each patch body 2. The fixing claw 1 is an unclosed annular structure. The gasket body 3 can be detachably installed inside the fixing claw 1. The gasket body 3 includes a longitudinal connecting portion 31 and a transverse connecting portion 32 integrally connected to both ends of the longitudinal connecting portion 31. The longitudinal connecting portion 31 is hollow, and the diameter of the transverse connecting portion 32 is larger than the longitudinal connecting portion 31. The diameter of the connecting portion 31, the transverse connecting portion 32 is coaxially arranged with the longitudinal connecting portion 31, and a plurality of first hollow grooves 33 and a plurality of second hollow grooves 34 are provided on the transverse connecting portion 32 and the longitudinal connecting portion 31, and the plurality of first hollow grooves 33 and the plurality of second hollow grooves 34 are equidistantly arranged around the central axis of the gasket body 3. By providing the first hollow grooves 33 and the second hollow grooves 34, a part of the shock waves generated by the operation of the fan can be absorbed, and the ventilation of the gasket body 3 can be increased, the heat dissipation of the fan can be promoted, and the influence of temperature and humidity on the gasket can be reduced, while making the gasket body 3 lighter, the production cost of the gasket body 3 is also reduced.

[0022] Further, such as Figure 1 As shown, an opening 11 is provided on the fixing claw 1, and the length of the opening 11 is smaller than the diameter of the fixing claw 1, wherein the fixing claw 1 can be made of a material with a certain toughness or some hard materials. When the gasket body 3 is installed into the fixing claw 1, if the fixing claw 1 is made of a material with a certain toughness, a force can be first applied to the opening 11 to enlarge the opening 11. After the gasket body 3 is placed into the fixing claw 1, the force on the opening 11 is released. After the fixing claw 1 recovers its deformation, the fixing claw 1 is wrapped around the outside of the longitudinal connecting portion 31, thereby preventing the gasket body 3 from falling off from the fixing claw 1 at will. When the fixing claw 1 is made of some hard materials, an extrusion force can be generated on the longitudinal connecting portion 31, causing the longitudinal connecting portion 31 to deform and enter the fixing claw 1 from the opening 11.

[0023] Further, such as Figure 3As shown, a plurality of elastic protrusions 4 are provided on the transverse connecting portion 32, and each elastic protrusion 4 is respectively located between two adjacent first hollow grooves 33. The elastic protrusion 4 can be integrally formed with the gasket body 3. After the transverse connecting portion 32 contacts with the external device, the elastic protrusion 4 will be squeezed first. After being subjected to pressure, the elastic protrusion 4 will be deformed, increasing the contact area and expanding the range of action of the damping force, thereby better absorbing and dispersing the vibration energy.

[0024] Further, such as Figure 1 As shown, the height of the longitudinal connecting portion 31 is equal to the height of the fixing claw 1, and the outer diameter of the longitudinal connecting portion 31 is equal to the inner diameter of the fixing claw 1, so that after the gasket body 3 is installed in the fixing claw 1, it can fully cooperate with the fixing claw 1, and the fixing claw 1 can provide a certain support to the gasket body 3, so that the gasket body 3 will not bend after being subjected to external force.

[0025] Further, such as Figure 1 As shown, a plurality of reserved grooves 5 are provided on the end face of the fixing claw 1. When the transverse connecting portion 32 is subjected to pressure, the extrusion force between the end face of the fixing claw 1 will increase. At this time, part of the transverse connecting portion 32 will enter and be inserted into the reserved groove 5. At this time, the friction force between the transverse connecting portion 32 and the fixing claw 1 will increase, thereby preventing the gasket body 3 from rotating randomly in the fixing claw 1, and achieving a better stabilization effect.

[0026] Further, such as Figure 1 As shown, the outer diameter of the transverse connecting portion 32 is equal to the outer diameter of the fixing claw 1, so that the transverse connecting portion 32 is completely fitted with the end surface of the fixing claw 1 when subjected to pressure, which not only provides a certain degree of protection for the fixing claw 1, but also improves the shockproof effect.

[0027] like Figure 1-Figure 3 As shown, the principle of the shock-proof gasket with a hollow structure provided in this embodiment is as follows: when in use, the gasket body 3 is conveniently installed in the fixing claw 1 through the opening 11 of the fixing claw 1. At this time, the transverse connecting part 32 contacts the upper end surface of the fixing claw 1, and the longitudinal connecting part 31 is just stuck in the fixing claw 1, so that the gasket body 3 is connected in the fixing claw 1. When the transverse connecting part 32 located at the upper end contacts the external device, it will first squeeze the elastic protrusion 4. The elastic protrusion 4 will deform after being subjected to pressure, thereby increasing the contact area and expanding the range of action of the damping force, so as to better absorb and disperse the vibration energy. At the same time, after the transverse connecting part 32 is subjected to pressure, it is in close contact with the end surface of the fixing claw 1, so that part of the transverse connecting part 32 is stuck in the reserved groove 5, so that the gasket body 3 and the fixing claw 1 will not rotate at will, and the stability is better.
