Abstract
The utility model relates to a damping protection device for a spiral spring, which is a plastic pad for the spiral spring. The utility model comprises an annular plastic body, wherein an opened mouth is arranged on the annular plastic body in an axial direction, grooves which can be embedded in the spring wire of the spiral spring are respectively arranged at annular end surfaces at the upper end and the lower end of the annular plastic body, and the annular plastic body is in a twist which can be formed by that the opened mouth is staggered and the ports of the grooves on the upper end surface and the lower end surface are corresponding. In the utility model, because the grooves are arranged on two end surfaces of the annular plastic body, the spring wire of the spiral spring is tightly embedded in the grooves, when the stress of the spiral spring is larger or the spiral spring is impacted suddenly, impact force is transferred to the plastic pad, and the utility model can protect the spiral spring and act a part in a buffer function. Because of the function of the plastic pad, the amount of the compression deformation of the spiral spring can not be oversize, the fatigue strength of the spiral spring can not be influenced in long-term use, and the stability and the service life of the spiral spring can be improved.
Description
Technical field
The utility model relates to a kind of damping device, relates in particular to a kind of helical spring shock-absorbing protecting device.
Background technique
Helical spring is as the resistance to compression damper element, in being commonly used in be stressed bigger equipment and device, but, there are some defectives in the use in present helical spring, stressed big or when being subjected to impacting suddenly as: (1) helical spring, its compress variation is increased, helical spring fatigue strength is reduced, even fatigue failure; (2) the spring effect of being stressed when compression, may be superimposed and collision mutually between its each adjacent spring silk fully, and this phenomenon can influence helical spring working life greatly; Therefore, present helical spring must in time be changed in use for some time, causes the waste in the use.
Summary of the invention
The purpose of this utility model is to provide a kind of helical spring plastic pad, and it can effectively protect helical spring, prolongs helical spring working life greatly.
The purpose of this utility model is to realize like this, a kind of helical spring plastic pad, comprise a ring plastic cement body, this ring plastic cement axon disconnects mouth to being provided with one, along the ring plastic cement body up and down the annular end face at two ends be respectively equipped with the groove that can embed helical spring spring silk, the ring plastic cement body can be by disconnecting that mouth staggers and the groove port of upper and lower end face is corresponding constitutes helical.
The cross section of described groove is the round-bottomed flask shape.
The described section that disconnects mouthful both sides forms the cambered surface of outside protrusion along the annular wall thickness direction.
Described ring plastic cement body side surface is provided with the through hole that connects inside and outside wall.
Described through hole is circle or prolate shape.
Described through hole is two or more.
Described each through hole and disconnection mouth upwards were symmetrically distributed in ring plastic cement body week.
The external side of described ring plastic cement is provided with stiffening rib.
Described stiffening rib is an annular setting.
Described stiffening rib is two or more.
Helical spring plastic pad of the present utility model, by on the both ends of the surface of ring plastic cement body, groove being set, helical spring spring silk is closely embedded in this groove, helical spring is stressed big or when being subjected to impacting suddenly, its impact force passes to plastic pad, can protect helical spring, play buffer function, simultaneously, because the effect of plastic pad, make the helical spring compress variation can be not excessive, the long-term helical spring fatigue strength of also unlikely influence that uses can improve helical spring stability and working life; When helical spring was subjected to force compresses, one of them adjacent spring silk in place can not collide mutually, avoided whole helical spring spring silk to be superimposed fully and collision mutually, therefore, can significantly improve helical spring working life.

Embodiment
As shown in Figure 1, 2, 3, a kind of helical spring plastic pad, comprise a ring plastic cement body 1, this ring plastic cement body 1 is axially arranged with one and disconnects mouth 2, annular end face along ring plastic cement body two ends about in the of 1 is respectively equipped with the groove 3,4 that can embed helical spring spring silk, and ring plastic cement body 1 can stagger and the groove 3 of upper and lower end face is corresponding with 4 ports constitutes helical by disconnecting mouthfuls 2.
As shown in Figure 3; in the present embodiment; helical spring plastic pad is by being provided with groove 3,4 on the both ends of the surface of ring plastic cement body 1; closely embed the spring silk 51 of helical spring 5 in this groove 3 and 4; helical spring 5 is stressed big or when being subjected to impacting suddenly; its impact force can pass to plastic pad; can protect helical spring 5; play buffer function; simultaneously, because the effect of plastic pad, make the compress variation of helical spring 5 can be not excessive; the long-term use the also unlikely fatigue strength that influences helical spring 5, stability and the working life that can improve helical spring 5.
During use, plastic pad can be placed between the two adjacent arbitrarily ring spring silks 51, and in the groove 3 and 4 with spring silk 51 embedding plastic pad two ends, when helical spring 5 is subjected to force compresses, at least the adjacent spring silk 51 in this place can not collide mutually, avoid the spring silk of whole helical spring 5 to be superimposed fully and collision mutually, therefore, can significantly improve the working life of helical spring 5.In the present embodiment, best mode of execution is plastic pad to be placed on the middle part of helical spring 5; Certainly, also can use a plurality of plastic pads according to actual needs, be placed between the two adjacent ring spring silks 51 of many places at interval respectively and use.
As shown in Figure 4; use the schematic representation of plastic pad of the present utility model for the helical spring of wheel top; can know expression among the figure; helical spring spring silk embeds the situation in the described groove; by this plastic pad is set on helical spring, make helical spring stressed big or when being subjected to impacting suddenly, its impact force can pass to plastic pad; can protect helical spring, play buffer function.
Further, as shown in Figure 1, 2, in the present embodiment, the cross section of described groove 3,4 is the round-bottomed flask shape, and promptly opening is little, and rounded in the groove, this structure is convenient to firm the snapping in of spring silk.
As shown in Figure 1, the described section that disconnects mouthful 2 both sides forms the cambered surface of outside protrusion along the annular wall thickness direction, and when this kind structure can work as this plastic body 1 pressurized, there was certain extension space cambered surface low side both sides, avoided stressed groove 3,4 afterwards to be torn.
Further, as shown in Figure 1, described ring plastic cement body 1 side is provided with the through hole 11 that connects inside and outside wall; Can be fixed in described groove 3 and 4 with the spring silk 51 of fixed block by described through hole 11 helical spring 5.Described fixed block can be cotton rope, promptly passes the upper and lower end face that through hole 11 is walked around ring plastic cement body 1 again with cotton rope, and the spring silk that embeds in the groove 3 and 4 is tied up admittedly, and when avoiding using, spring silk 51 is deviate from from groove 3 and 4.
