Abstract
A kind of flat ring-shaped rubber vibration isolator of small size disclosed in the utility model, it is desirable to provide a kind of rigidity is small, vibration and impact isolating effect are good, the flat ring-shaped rubber vibration isolator of service life length.The utility model is achieved by following technical proposals：The double plate head clamping screw rod (1) of two hardwares lower through-hole (3) on by the flat ring (2) of rubber vibration isolation elasticity, which passes to connect firmly, up and down on anchor ring, to be passed through the flat ring (2) of rubber vibration isolation elasticity in the flat ring (2) of rubber vibration isolation elasticity and provides rigidity and damping characteristic required for decay vibration and impact energy.The utility model avoid prior art flexible member it is Nian Jie with metal structure when the problem of easily tearing, peeling off, effectively extend service life.
Description
Technical field
It the utility model is related to a kind of flat ring-shaped rubber vibration isolator of small size, the electronic equipment internal that is particularly suitable for use in lightweight group
The flat ring-shaped rubber vibration isolator of small size of the local vibration isolation of part.
Background technology
Electronic equipment can be by the vibration of separate sources and acting on for shock loading, at these during transport, use
The pin of the element of electronic equipment in the presence of load, solder joint link easily produce overstress and the cracked electric signal that influences
Continuity, or even open circuit and then cause the forfeiture of electronics portion or repertoire.In order to protect electronic equipment make its by
Normal function is kept during to extraneous vibration and impact, engineer makes electronic equipment be shaken with the external world frequently with vibration isolator in practice
It is dynamic to isolate with shock loading.Rubber is a kind of high polymer material, and modified rubber material has resistance to environmental characteristics and damping well
Characteristic, and various complicated shapes can be molded into the help of mould.Exactly it is used for the excellent characteristic of elastomeric material, its quilt
It is used as the elasticity and damping element of vibration isolator extensively, for vibrating the isolation with shock loading.
Currently, Small Rubber Vibration Isolator is generally using the metal double plate head clamping screw rod knot Nian Jie with rubber elastic element
Configuration formula, and flexible member is the form such as cylinder, disk, round platform, prism or bucking ladder, using the axial direction of flexible member to bear to carry
The principal direction of lotus.These vibration isolators expose many deficiencies in actual use, specific as follows：
Rigidity is big, and the effect of isolation vibration and impact is undesirable.In elastomeric material in cylindrical elastomeric element rubber shock absorber
Rigidity after it is determined that reduces with the increase of axial dimension, is limited yet with the axial dimension of Small Rubber Vibration Isolator
System, rigidity is typically all bigger, and the effect for causing isolation to vibrate and impact is undesirable, can normally only attenuate 30% energy.
It is particularly true during in particular for light load vibration isolation.
The junction of metal and flexible member is easily torn, and service life is short.The metal of current Small Rubber Vibration Isolator
Part is more to use Nian Jie connected mode with rubber elastic element, in the presence of the dynamic load such as vibration and impact therebetween
Easily occur peeling off and damaging, shorten the shelf life of vibration isolator.
The content of the invention
In order to overcome big prior art Small Rubber Vibration Isolator rigidity, vibration and impact isolating effect are undesirable, use
The weak point of short life, it is good, service life length small that the utility model provides a kind of small rigidity, vibration and impact isolating effect
The flat annular glue vibration isolator of size rubber.
The utility model be solve the technical scheme that uses of its technical problem for：A kind of flat ring-shaped rubber vibration isolation of small size
Device, including a flat ring 2 of rubber vibration isolation elasticity, it is characterised in that：Two hardware double plate head clamping screw rods 1 pass through rubber backwards
Lower through-hole 3 passes to connect firmly on the flat ring 2 of glue vibration isolation elasticity up and down on anchor ring, passes through rubber vibration isolation in the flat ring 2 of rubber vibration isolation elasticity
The flat ring 2 of elasticity provides the rigidity and damping characteristic required for decay vibration and impact energy.
What the utility model obtained has the beneficial effect that：
Simple for structure, long lifespan.The utility model only has 3 parts to form, including two double plate head clamping screw rods, one
The flat ring resilience element of rubber vibration isolation elasticity, the flexible member of the double plate head clamping screw rod and the flat ring of rubber vibration isolation elasticity of metal material
Between use physical link, avoid prior art flexible member it is Nian Jie with metal structure when the problem of easily tearing, peeling off, have
Effect extends service life.
Rigidity is low, vibration, impact isolating suitable for small quality electronic component.Flexible member of the present utility model is flat ring
Shape, the offer elasticity of two curved sections is provided, completes vibration, the isolation of impact, support stiffness is low, when carrying small quality
Enough deflections can still be produced with vibration and the impact energy of decaying.
Brief description of the drawings

Fig. 2 the utility model elastic element structure schematic diagrames
In figure, 1 double plate head clamping screw rod, the flat ring of 2 rubber vibration isolations elasticity, 3 through holes.
Embodiment
The utility model is referred to following examples and is achieved.
Refering to Fig. 1, Fig. 2.In embodiment described below, a kind of flat ring-shaped rubber vibration isolator of small size, including one
The flat ring 2 of rubber vibration isolation elasticity, two hardware double plate head clamping screw rods 1 lead to backwards to by the flat ring of rubber vibration isolation elasticity about 2
Hole 3 passes to connect firmly up and down on anchor ring, to be passed through the flat ring 2 of rubber vibration isolation elasticity and provides decay vibration in the flat ring 2 of rubber vibration isolation elasticity
With the rigidity and damping characteristic required for impact energy.
In the utility model, the flat ring of rubber vibration isolation elasticity is continous way overall structure, and thickness is uniform, by flat segments and curve
Section is formed, and the middle position of flat segments is designed with through hole.
In the utility model, one end of double plate head clamping screw rod 1 is screw thread, and the other end is to connect with the flat ring of rubber vibration isolation elasticity
Binding structure.
In the utility model, barrier piece disk and the flat annular of rubber vibration isolation elasticity that double plate head clamping screw rod 1 passes through its one end
Into physical connection, the separation both in stand under load is avoided.
In the utility model, the fixing end of double plate head clamping screw rod 1 is provided with two barrier piece disks.
In the utility model, using the hole in the elastic dilatation of the flat ring 2 of rubber vibration isolation elasticity its flat segments, then load double
Coiled hair clamping screw forms physical link therebetween.
