The specific embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.As Fig. 1, Fig. 2 and shown in Figure 6, a kind of shock absorber that the embodiment of the invention provides, it can be used on equipment, instrument or the platforms such as light fixture 600, optical instrument, in the present embodiment, use it on the light fixture 600, above-mentioned shock absorber comprises first installing plate 110, second installing plate 120, damping component 300 and connecting elements 200, the first installing plates 110 and the 120 spacing settings of second installing plate; Connecting elements 200 comprise space ring 210, by the end face of described space ring 210 along its axially to head rod portion 220 that a side is extended and by the end face of described space ring along it axially to the second connecting rod portion 230 (with reference to shown in Figure 5) that opposite side extends, 220 activities of head rod portion are arranged in 230 activities of first installing plate, 110, the second connecting rod portions and are arranged in second installing plate 120; Offer the perforation 111 that can supply head rod portion 220 to wear on first installing plate 110, the size of perforation 111 is greater than the diameter of head rod portion 220, first installing plate 110 not only can be moved relative to second installing plate 120, also can be relative second installing plate 120 tilt, deflection; Damping component 300 is located between first installing plate 110 and second installing plate 120, damping component 300 comprises first elastic component 310 and second elastic component 320, first elastic component 310 is sheathed on head rod portion 220, one end of first elastic component 310 supports and terminates in first installing plate 110, and the other end supports the upper end that terminates in space ring 210; The end that second elastic component 320 is sheathed on the second connecting rod portion, 230, the second elastic components 320 supports the lower end that terminates in space ring 210, and the other end supports and terminates in second installing plate 120.Head rod portion 220 is arranged with first locking member 410 in first installing plate, 110 tops, the second connecting rod portion 230 is arranged with second locking member 420 in second installing plate, 120 belows, so that damping component 300 can be positioned between first installing plate 110 and second installing plate 120; First locking member 410 and second locking member 420 are nut, can select standard component for use, can directly purchase on market, are easy to preparation, help reducing cost, and are convenient to install.During use, light fixture 600 is fixed on first installing plate 110, second installing plate 120 is fixed on the installed surface, by such design, the vibration of light fixture 600 is passed on first elastic component 310 and second elastic component 320 by first installing plate 110 and space ring 210, and by the elastic shear of first elastic component 310 and second elastic component 320, the energy that compression is vibrated with absorption.Particularly, when light fixture 600 is subjected to vertical or axial vibrational excitation, first installing plate 110 will be compressed first elastic component 310 and second elastic component 320 to the direction translation of second installing plate 120, reach the purpose of vibration damping.When light fixture 600 is subjected to level or vibrational excitation radially, first installing plate 110 will be installed inclination relatively down and compress first elastic component 310, connecting elements 200 and space ring 210 will tilt synchronously with first installing plate 110 this moment, first installing plate 110 will compress first elastic component 310, simultaneously, space ring 210 will compress second elastic component 320, spaced apart by the space ring 210 that first elastic component 310 and second elastic component, 320 usefulness is convexly set in connecting elements 200 stage casings, the vibrational excitation that light fixture 600 is subjected to can be distinguished simultaneously by first elastic component 310 and second elastic component, 320 bufferings, the amplitude and the frequency of vibration are decayed rapidly, thereby reach vibration damping, shock proof purpose, reduce user's use cost and maintenance cost, simple in structure, assemble simple and easy, help extensive popularization and application, can prolong the service life of light fixture 600, improve reliability of products, bring maximum economic benefits to the user.If no space ring 210 on the connecting elements 200, when product is subjected to level or vibrational excitation radially,, will make connecting elements 200 inclinations and angle of inclination bigger because inelastic component is supported on the connecting elements 300, resistance to shock is relatively poor, and the position of damping component 300 is offset easily; By space ring 210 being set and second elastic component 320 that can support space ring 210 being set, when product is subjected to level or vibrational excitation radially, space ring 210 can act on second elastic component 320, the inclination of connecting elements 200 there is the effect of inhibition, avoided connecting elements 200 angles of inclination excessive, and the position of damping component 300 is difficult for skew, and resistance to shock is good, the product reliability height.
