Description
Technical field
The utility model relates to a kind of vibration isolator, particularly a kind of enclosed type spring metal-rubber composite vibration isolator.
Background technique
The design of the rubber combined formula vibration isolator of existing spring metal, is typically employed in the structural type of the in-built metal-rubber pad of cylindrical spring.During motion, by extrusion metal rubber pad, make Relative sliding between wire, produce dry friction dissipate significant energy, can provide and well support rigidity and damping, play good vibration isolation, buffer function.But in working long hours, along with the wearing and tearing between wire increase, can metal fragment be dropped out, affect the safe operation of electronic equipment.In actual applications, the rubber combined formula vibration isolator of existing spring metal is mainly applicable to the equipment do not required this kind of situation, strongly limit the Environmental Conditions of vibration isolator.
Summary of the invention
The technical problem that the utility model solves: provide a kind of good sealing effect, the simple spring metal rubber composite vibration isolator of structure.
The technical solution of the utility model: described vibration isolator comprises top cap 1, upper cover 2, upper ring plate 3, metal-rubber pad (4,5), spring 6, base plate 7 and pedestal 8, top cap 1 is the cavity body structure of hollow, be positioned at pedestal 8, base plate 7 is fixed on the bottom of pedestal 8, be provided with spring 6 in the cavity of top cap 1, spring 6 is between top cap 1 and base plate 7;
Metal-rubber pad is filled with between the sidewall of top cap 1 and the side wall inner surfaces of pedestal 8, metal-rubber pad is divided into two-layer up and down by boss, upper cover 2 is fixed on the upper end of top cap 1 by screw thread, between metal-rubber pad and upper cover 2, ring plate 3 is installed, upper ring plate 3 is pressed on metal-rubber pad by upper cover 2, and upper ring plate 3 is ring.
One as the technical program is improved, ring plate 9 in being provided with between boss and metal-rubber pad.Ring plate 9 in this is set, the wearing and tearing of boss to metal-rubber pad can be alleviated, improve the working life of metal-rubber pad.
One as the technical program is improved, and metal-rubber pad is made up of metal spiral silk.The metal-rubber pad that this kind of material is made, elastic restoring force is strong, improves the sealing effect of whole vibration isolator.
The beneficial effects of the utility model: a) this New Type Vibration Isolator Using overcomes the shortcoming that former spring metal rubber combined formula vibration isolator metal-rubber pad exposes, solve the unfavorable problem that chip appears in the wearing and tearing of metal-rubber pad, improve electronic equipment safety in utilization.
B) spring and metal-rubber pad separate, improve the designability of vibration isolator, the Environmental Conditions of vibration isolator obtains very large expansion.
C) Structural Hardware of metal-rubber pad surrounding, objectively for it acts as metal frame, improve the bearing capacity of vibration isolator, substantially prolongs the working life of vibration isolator.
Accompanying drawing explanation
Fig. 1 is: longitudinal sectional view of the present utility model;
Fig. 2 is: plan view of the present utility model;
In figure, 1 is top cap, and 2 is upper cover, and 3 is upper ring plate, and 4 is upper metal-rubber pad, and 5 is lower metal-rubber pad, and 6 is spring, and 7 is base plate, and 8 is pedestal, and 9 is middle ring plate.
Embodiment
Below in conjunction with accompanying drawing, the technical program is described in further detail.
As illustrated in fig. 1 and 2, described vibration isolator comprises top cap 1, upper cover 2, upper ring plate 3, metal-rubber pad (4,5), spring 6, base plate 7 and pedestal 8, top cap 1 is the cavity body structure of hollow, be positioned at pedestal 8, base plate 7 is fixed on the bottom of pedestal 8, be provided with spring 6 in the cavity of top cap 1, spring 6 is between top cap 1 and base plate 7;
Metal-rubber pad is filled with between the sidewall of top cap 1 and the side wall inner surfaces of pedestal 8, metal-rubber pad is divided into two-layer up and down by boss, upper cover 2 is fixed on the upper end of top cap 1 by screw thread, between metal-rubber pad and upper cover 2, ring plate 3 is installed, upper ring plate 3 is pressed on metal-rubber pad by upper cover 2, and upper ring plate 3 is ring.Ring plate 9 in being provided with between boss and metal-rubber pad.Ring plate 9 in this is set, the wearing and tearing of boss to metal-rubber pad can be alleviated, improve the working life of metal-rubber pad.Metal-rubber pad is made up of metal spiral silk.The metal-rubber pad that this kind of material is made, elastic restoring force is strong, improves the sealing effect of whole vibration isolator.
In the utility model vibration isolator, the axial rigidity of vibration isolator is provided jointly by upper metal-rubber pad 4, lower metal-rubber pad 5, spring 6.Compression upper metal-rubber pad 4, lower metal-rubber pad 5 and the spring 6 when the top cap 1 of vibration isolator moves up and down, between metal-rubber pad wire, phase mutual friction provides damping for vibration isolator, and damping also changes thereupon when the load is varied.The lateral rigidity of vibration isolator and damping are except jointly being provided by upper metal-rubber pad 4 and lower metal-rubber pad 5 and spring 6, and the dry friction between upper cover 2 and upper ring plate 3 also participates in providing.During lateral vibration, by metal-rubber pad 4 and lower metal-rubber pad 5 in cap 1 lateral compression of top, simultaneously Relative sliding between upper cover 2 and upper ring plate 3, between them, phase mutual friction provides damping and consumed energy; Top cap 1 lateral movement drives spring 6 lateral movement, produces elastic potential energy, and consume portion of energy and provide lateral rigidity, rigidity changes with the displacement amount of side direction.
Upper metal-rubber pad 4 and lower metal-rubber pad 5 are closely wrapped up by upper cover 2, upper ring plate 3 and pedestal 8, base plate 7 and pedestal 8, the chip caused that weares and teares between wire can not drop out vibration isolator outside, substantially increase the Security of electronic equipment, vibration isolator has excellent vibration isolating effect simultaneously.
