Abstract
The utility model discloses a low-frequency spring rubber vibration damper structure. The structure comprises an upper steel member and a lower steel member, and is characterized in that the lower steel member is connected with the upper steel member; rubber is arranged at the joint of the lower steel member and the upper steel member; the top of the rubber is connected with a middle push plate; the middle push plate is connected with a spring; the spring is arranged in the interior of the upper steel member; the other end is connected with the inner wall of the upper steel member; and the spring is formed by three parallelly-connected springs. The structure is small in size, compact, easy to produce and process and capable of absorbing impact energy and isolating high/low frequency vibration.
Description
Technical field
The utility model relates to a kind of damper structure, is specifically related to a kind of low frequency spring-rubber damper structure.
Background technique
Vibration damper is divided into conventionally: metal spring vibration damper, air spring vibration reduction device, viscoelastic material vibration damper and Coulomb friction vibration damper, at present, most domestic electronic equipment, precision type instrument or equipment adopt metal spring vibration damper conventionally, such vibration damper, actual functional capability is pooling feature, the vibrational energy losing quantity of system is very little, metal spring vibration damper is worked under very large and mordant rugged environment in temperature variation, there is no stagnant moving, creep, allowed larger displacement deformation, low frequency vibration isolation is effective, but because of its damping constant very little, vibration isolation efficiency while having reduced high frequency, viscoelastic material vibration damper has buffering and has again power consumption effect, and high-frequency vibration isolation efficiency is high, has larger damping, can well suppress resonance peak, but low frequency vibration isolation performance is low, only can meet conventional requirement.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of low frequency spring cushion structure, this apparatus structure volume is little, compact structure, production and processing convenient, can apparatus with shock absorbing, can isolate low-and high-frequency vibration.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of low frequency spring cushion structure, comprise upper steel piece and lower steel piece, it is characterized in that: on lower steel piece, be connected with upper steel piece, at lower steel piece and upper steel piece connection mouth place, be provided with rubber, push pedal in the middle of rubber top is connected with, in middle push pedal, be connected with spring, spring is positioned at upper steel piece inside and the other end is connected with upper steel piece inwall.
Described spring is to be formed in parallel by three springs.
The beneficial effects of the utility model are:
1) spring adopts three springs to be formed in parallel, and can regulate by changing spring cross-sectional sizes, the number of turns and quantity the rigidity value of vibration damper;
2) can regulate by changing the material prescription of silicone rubber the damping value of vibration damper;
3) helical spring is connected with vibration-proof rubber, can reduce helical spring surge, and to wipe a biography while shaking the effect of shaking large to reducing surge.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In figure: 1-upper steel piece; 2-lower steel piece; 3-rubber; Push pedal in the middle of 4-; 5-spring.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of low frequency spring cushion structure, comprise upper steel piece 1 and lower steel piece 2, on lower steel piece 2, be connected with upper steel piece 1, at lower steel piece 2, be provided with rubber 3 with upper steel piece 1 connection mouth place, push pedal 4 in the middle of rubber 3 tops are connected with, is connected with spring 5 in middle push pedal 4, and spring 5 is positioned at upper steel piece 1 inside and the other end is connected with upper steel piece 1 inwall.
Spring 5 is to be formed in parallel by three springs.Can regulate by changing spring 5 cross-sectional sizes, the number of turns and quantity the rigidity value of vibration damper.
The utility model is to implement like this: helical spring 5 is connected with vibration-proof rubber 3, can reduce the surge of helical spring 5, and it is large that reduction surge is wiped to a biography while shaking the effect of shaking.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
