Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes.
As shown in Fig. 1 ~ Fig. 3, a kind of vibration absorber provided in an embodiment of the present invention, including mounting disc 1, solid in mounting disc 1
It is provided with a perpendicular guide pillar 2, mounting disc 1 and guide pillar 2 can be integrally formed, and guide pillar 2 is arranged in an installation set 3, on guide pillar 2
It is arranged with a spring 4 being located in installation set 3, the upper end of spring 4 is abutted with the upper end of installation set 3, and the lower end of spring 4 is solid with one
Stop part 5 located at guide pillar 3 lower end abuts, and stop part 5 is in installation set 3.
When the present invention vibration absorber be used for vibration damping when, first by the lower end of installation set 3 with need dampening apparatus (as light fixture)
It is fixedly connected, then mounting disc 1 is fixed to place (as ceiling) to be installed, due to needing the deadweight of dampening apparatus, needs vibration damping
Equipment moves downwardly together with installation set 3, and spring 4 is compressed during moving downward by installation set 3.It is subject to when needing dampening apparatus
During to vibratory impulse, need dampening apparatus can teetertotter, installation set 3 also teetertotters therewith, the spring 4 in installation set 3 is therewith
Produce certain stroke, vibrational energy is cut out by spring 4 using the dilatation of its own, thus realizing the mesh of vibration damping
's.
The dampening apparatus that the present invention provides, can effectively offset axial direction from installation set 3 to the vibration needing dampening apparatus
Impact is it is ensured that need the normal use of dampening apparatus.
To the present invention, each part describes in detail below.
Referring again to Fig. 1 ~ Fig. 3, described installation set 3 includes a fixed plate 31 and and connected vertically with fixed plate 31 leads
Set 32, the inwall of guide pin bushing 32 upper end be provided with one along its axis around setting flange 33, guide pin bushing 32 includes being sequentially connected and coaxially
The first through hole 34 of setting and the second through hole 35, by flange 33 around being formed, the diameter of first through hole 34 is less than first through hole 34
The diameter of the second through hole 35, first through hole 34 is located at the upper end of guide pin bushing 32, and the second through hole 35 extends to from the upper end of guide pin bushing 32 leads
Fixed plate 31 is simultaneously run through in the lower end of set 32.During assembling, guide pillar 2 is arranged in first through hole 34 and the second through hole 35, spring 4 and only
In the second through hole 35, the upper end of spring 4 is abutted block piece 5 with flange 33, and the lower end of spring 4 is abutted with stop part 5, stop part
5 are fixedly connected with the lower end of guide pillar 2 by a screw 6.In the present embodiment, stop part 5 is a pad；In other embodiments,
Stop part 5 can also be the wider locking member of a head, and this locking member is directly anchored to the lower end of guide pillar 2, and this locking
The head of part is abutted with the lower end of spring 4.
When needing dampening apparatus impact vibrated, need dampening apparatus can teetertotter, installation set 3 is also shaken therewith up and down
Dynamic, the upper end due to spring 4 is abutted with flange 33, and the lower end of spring 4 is abutted with stop part 5, therefore, when installation set 3 is transported upwards
When dynamic, the flange 33 of installation set 3 upper end is progressively disengaged with spring 4 and contacts, and spring 4 gradually recovers former length by compressive state, works as peace
When encapsulation 3 moves downward, the further compression spring 4 of flange 33 of installation set 3 upper end, so, spring 4 shakes about 3 in installation set
The vibrational energy needing dampening apparatus to be subject to can be cut out by the certain stroke producing during dynamic, realizes to needing vibration damping
Equipment carries out the purpose of vibration damping.
In the present embodiment, described spring 4 and stop part 5 are all coordinated with the second through hole 35 gap, permissible in order to installation set 3
Freely move up and down and unobstructed, but the gap of spring 4 and stop part 5 and the second through hole 35 can not be excessive, otherwise, installation
Set 3 can be partial to (axial direction deviateing installation set 3) during moving up and down, thus affecting effectiveness in vibration suppression.It is preferred that the
The diameter of two through holes 35 2 ~ 5mm bigger than the diameter of spring 4 and stop part 5 respectively, so both ensure that spring 4 and stop part 5 with
The gap cooperation of the second through hole 35, in turn ensure that installation set 3 will not be partial to during moving up and down, further ensures
Effectiveness in vibration suppression.
The embodiment of the present invention additionally provides a kind of light fixture (not shown), and it includes lamp body, lamp holder and subtracts as previously described
Vibrating device, the fixed plate 31 of this vibration absorber is fixedly connected with lamp body, and mounting disc 1 is fixedly connected with ceiling.Using this vibration damping
The light fixture of device, when light fixture impact vibrated, light fixture can teetertotter, and installation set 3 also teetertotters therewith, installation set 3
Interior spring 4 produces certain stroke therewith, and vibrational energy is cut out by spring 4 using the dilatation of its own, thus
Realize light fixture being carried out with the purpose of vibration damping it is ensured that the part of the shock resistance such as the bulb of lamp interior, electric ballast difference will not
Fall off the normal use it is ensured that light fixture because of light fixture impact vibrated, improve the service life of light fixture.
The above is the preferred embodiment of the present invention it is noted that for those skilled in the art
