Abstract
The utility model discloses a kind of damping noise reduction spring, belong to component of machine field.Described damping noise reduction spring comprises spring body, the sleeve pipe be arranged on described spring body; The center line of described spring body is circular arc; Described sleeve pipe comprises the absorption internal layer and protection skin that superpose setting successively.The utility model is by arranging absorption internal layer and protection is outer, and reduce spring and to be hit by a bullet the vibration and noise that spring coil collision produces at telescopic process, extend working life, structure is simple, easy to use.
Description
Technical field
The utility model relates to component of machine field, particularly a kind of damping noise reduction spring.
Background technique
Spring is a kind of mechanical parts utilizing elasticity to carry out work, in order to control mechanical motion, to relax the size etc. impacting or shake, store up energy, measuring force, is widely used in machine, instrument.
Now widely used spring, spring material diameter of section is comparatively large, and bearing capacity is high.
Realizing in process of the present utility model, inventor finds that prior art at least exists following problem:
In the compression of telescopic process medi-spring, between spring ring there is noise abnormal sound, the Environmental Conditions of spring noise effect spring in collision.
Have notification number be CN202468809U patent discloses a kind of damping noise reduction spring, comprise spring body, it is characterized in that: described spring body is socketed with body, described body two ends is closed, described body comprises the internal layer of flexible outer layer and adsorption storage liquid, but the spring of this structure is in the process used, still can there is larger shock between spring body, still can there is larger vibrations and noise.
Model utility content
In order to solve the problem of prior art, the utility model embodiment provides a kind of damping noise reduction spring.Described technological scheme is as follows:
The utility model embodiment provides a kind of damping noise reduction spring, and described damping noise reduction spring comprises spring body, the sleeve pipe be arranged on described spring body; Described sleeve pipe comprises the absorption internal layer and protection skin that superpose setting successively; described spring body is a spring silk one winding shaping; described spring body two ends are end of conflicting; described spring silk continues again to be inwardly wound around the turriform spring being bent to form reduced diameter after bending and extending to end of conflicting, described in be located at spring body two ends turriform spring mutually offset.
Particularly, described absorption subsurface adsorption has lubricant oil or lubricating grease.
Particularly, described absorption internal layer is cotton absorption internal layer.
Particularly, the center line of described spring body is circular arc; Described protection is outer is nylon protection skin.
Particularly, ringwise, described annular is provided with an opening to the outer cross section of described protection.
The beneficial effect that the technological scheme that the utility model embodiment provides is brought is:
By arranging absorption internal layer and protection skin; reduce spring telescopic process be hit by a bullet spring coil collision produce vibration and noise; extend working life; structure is simple; easy to use, simultaneously by the setting of turriform spring, overlaped by the spring ring when compressing on it at spring; effectively decrease the shock between spring ring, reduce vibration and noise that spring collides generation in telescopic process further.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the damping noise reduction spring that the utility model embodiment provides;
Fig. 2 is the partial view in Fig. 1;
Fig. 3 is the turriform spring structure schematic diagram of the damping noise reduction spring that another embodiment of the utility model provides.
Embodiment
For making the purpose of this utility model, technological scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model mode of execution is described in further detail.
The utility model embodiment provides a kind of damping noise reduction spring, and see Fig. 1, described damping noise reduction spring comprises spring body 1, the sleeve pipe 2 be arranged on spring body 1.
Particularly, the center line of spring body 1 is circular arc.
Particularly, see Fig. 2, sleeve pipe 2 comprises the absorption internal layer 21 and protection outer 22 that superpose setting successively, and absorption internal layer 21 is adsorbed with lubricant oil or lubricating grease, can prevent spring from getting rusty, and improves spring working life.
Preferably, internal layer 21 is adsorbed for cotton absorption internal layer.Protection outer 22 is nylon protection outer 22.
Ringwise, described annular is provided with an opening 221 to the outer cross section of described protection.This design is convenient to protection skin and is set on spring.Wherein, described spring body becomes straight tube shape, described spring body is a spring silk one winding shaping, described spring body two ends are end of conflicting, described spring silk continues again to be inwardly wound around the turriform spring 5 being bent to form reduced diameter after bending and extending to end of conflicting, described in be located at spring body two ends turriform spring 5 mutually offset.This design makes spring of the present utility model have double-deck spring body, has stronger elastic force, described in be located at spring body two ends turriform spring 5 mutually offset, further reduce the generation of noise simultaneously.
The beneficial effect that the technological scheme that the utility model embodiment provides is brought is:
By arranging absorption internal layer and protection skin; reduce spring telescopic process be hit by a bullet spring coil collision produce vibration and noise; extend working life; structure is simple; easy to use, simultaneously by the setting of turriform spring, overlaped by the spring ring when compressing on it at spring; effectively decrease the shock between spring ring, reduce vibration and noise that spring collides generation in telescopic process further.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
