The specific embodiment

As Fig. 1-shown in Figure 4, the vibration absorber that is used for lamp installation that present embodiment provides, it comprises that base 100, band shear horizontal vibration isolation rubber piece 200 and the longitudinal damping block rubber 300 and the loam cake 400 on inclined-plane.

Base 100 surrounds four sidewalls of sealing rectangular inner cavity 102 to be formed by base plate 101 and on base plate 101, is provided with four installing holes 103 on the base plate 101 outside four sidewalls, is used for by screw at installation material.Installing hole 103 numbers can suitably increase or reduce, and mainly are to guarantee and the fixedlying connected of installation material.

Four inwalls in base rectangular inner cavity 102 are provided with 4 vibration isolation rubber pieces, be respectively two second vibration isolation rubber pieces 300 that are oppositely arranged on two first vibration isolation rubber pieces 200 that are oppositely arranged and another direction in one direction, these block rubbers 200,300 can be made by oil resistant, the ageing-resistant rubber of shore hardness between 30～60 degree, wherein, each vibration isolation rubber piece is arranged to shear inclined-plane (201,301) respectively towards the face at base 100 centers, and above-mentioned each inclined-plane and bottom surface angle are the 95-130 degree.Wherein, the composition of used rubber is neoprene, silicon rubber, butyl rubber, natural rubber or its combination.For the first and second vibration

isolation rubber pieces

200 and 300 are adjacent to each other, can establish in the bottom of the first and second vibration

isolation rubber pieces

200 and 300

groove

202 and 302 is installed, be used to improve its deformability, thereby improve the ability that it absorbs vibrational energy.Importantly, the second yielding rubber piece 300 of the two relative settings with two of the first vibration isolation rubber piece 200 that are provided with relatively respectively forms four and shears the inclined-plane, can join with face way of contact realization elasticity with loam cake 400, allows rubber produce detrusion along shearing the inclined-plane.

Loam cake 400 adopts the integrated compacting of rigid material mold pressing such as metal to form, and an end face and four skew walls 401 are arranged, and the shearing inclined-plane 201,301 with two first vibration isolation rubber pieces 200 and two second vibration isolation rubber pieces 300 joins respectively.Loam cake 400 end face middle positions are provided with the installing hole 402 that is used to install by vibration damping object such as light fixture.Constituting sealing with incorporate four skew walls 401 of end face surrounds, be used for by realizing the conduction of vibration between two first vibration isolation rubber pieces 200 and two second vibration isolation rubber pieces 300 and base 100 and installation material such as the body of wall etc., vibration isolation rubber piece 200 therebetween and 300 can absorb vibrational energy, reduction from the vibration of installation material, base 100 to by the influence of vibration damping thing.Four skew walls of loam cake 400 form sealing and surround, and are hollow in the middle of surrounding, and promptly reach the vibration damping conduction function, can save metal material again.The thickness of skew wall depends on the designing requirement of vibration absorber.For example, for reaching better effectiveness in vibration suppression,, adjust the material and the size of the first vibration isolation rubber piece 200 and the second vibration isolation rubber piece 300 according to the size and the material installed weight of vibrational energy.

Use vibration absorber of the present invention to be used for lamp installation as shown in Figure 5; light fixture 600 is fixed on the loam cake 400 of vibration absorber by support 500; in vibration processes; extruding by 400 pairs of four vibration isolation rubber pieces 200,300 of vibration absorber loam cake; make horizontal vibration isolation rubber piece 200 and the 300 generation compressions of longitudinal damping block rubber and detrusion absorb the energy of vibration; therefore have only a part seldom to pass on the light fixture after the absorption of vibrational energy by vibration absorber of installation material such as body of wall etc., thereby protected light fixture.Vibration absorber of the present invention also can be installed other article, for example camera, projecting apparatus etc.

Above embodiment has only expressed preferred implementation of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention; Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention; Therefore, all equivalents and modifications of being done in claim scope of the present invention all should belong to the covering scope of claim of the present invention.
