In order to be illustrated more clearly in technical scheme of the present invention, the below will do to introduce simply to the accompanying drawing of required use among the embodiment, apparently, accompanying drawing in the following describes only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the three-dimensional installation diagram of the vibration absorber that provides of the embodiment of the invention;
Fig. 2 is the decomposing schematic representation of Fig. 1;
Fig. 3 be Fig. 1 partly cut open schematic diagram.
The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described.
Such as Fig. 1 ~ shown in Figure 3, a kind of vibration absorber that the embodiment of the invention provides, comprise mounting disc 1, be installed with a perpendicular guide pillar 2 in the mounting disc 1, mounting disc 1 and guide pillar 2 can be one-body molded, and guide pillar 2 is arranged in the installation sleeve 3, be arranged with a spring 4 that is positioned at installation sleeve 3 on the guide pillar 2, the upper end butt of the upper end of spring 4 and installation sleeve 3, the lower end of spring 4 and are fixedly arranged on stop part 5 butts of guide pillar 3 lower ends, and stop part 5 is located in the installation sleeve 3.
When vibration absorber of the present invention is used for vibration damping, at first the lower end with installation sleeve 3 is fixedly connected with needing dampening apparatus (such as light fixture), then mounting disc 1 is fixed to place to be installed (such as ceiling), owing to need the deadweight of dampening apparatus, need dampening apparatus to move downward together with installation sleeve 3, in the process that installation sleeve 3 moves downward spring 4 is compressed.When the need dampening apparatus is subject to vibratory impulse, need dampening apparatus to teetertotter, installation sleeve 3 also teetertotters thereupon, and the spring 4 in the installation sleeve 3 produces certain stroke thereupon, spring 4 utilizes the dilatation of himself that vibrational energy is cut out, thereby realizes the purpose of vibration damping.
Dampening apparatus provided by the invention can effectively be offset the axial vibratory impulse to the need dampening apparatus from installation sleeve 3, need to have guaranteed the normal use of dampening apparatus.
Below each part of the present invention is described in detail.
Please consult again Fig. 1 ~ Fig. 3, described installation sleeve 3 comprises a fixed head 31 and one and fixed head 31 guide pin bushings 32 connected vertically, the inwall of guide pin bushing 32 upper ends is provided with one along the flange 33 of its axis around setting, guide pin bushing 32 comprises the first through hole 34 and the second through hole 35 that connects successively also coaxial setting, the first through hole 34 by flange 33 around forming, the diameter of the first through hole 34 is less than the diameter of the second through hole 35, the first through hole 34 is positioned at the upper end of guide pin bushing 32, and the second through hole 35 extends to the lower end of guide pin bushing 32 and runs through fixed head 31 from the upper end of guide pin bushing 32.During assembling, guide pillar 2 is arranged in the first through hole 34 and the second through hole 35, and spring 4 and stop part 5 are located in the second through hole 35, the upper end of spring 4 and flange 33 butts, the lower end of spring 4 and stop part 5 butts, stop part 5 is 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 also can be a locking member that head is wider, and this locking member directly is fixed on the lower end of guide pillar 2, and the lower end butt of the head of this locking member and spring 4.
When the need dampening apparatus is subject to vibratory impulse, need dampening apparatus to teetertotter, installation sleeve 3 also teetertotters thereupon, because upper end and flange 33 butts of spring 4, the lower end of spring 4 and stop part 5 butts, therefore, when installation sleeve 3 moved upward, flange 33 and the spring 4 of installation sleeve 3 upper ends disengaged gradually, and spring 4 recovers former length gradually by compressive state, when installation sleeve 3 moves downward, the flange 33 further Compress Springs 4 of installation sleeve 3 upper ends, like this, certain stroke that spring 4 produces in installation sleeve 3 teetertotters process, the vibrational energy that the need dampening apparatus can be subject to cuts out, and realizes the need dampening apparatus is carried out the purpose of vibration damping.
In the present embodiment, described spring 4 and stop part 5 all with the second through hole 35 matched in clearance, it is not interrupted so that installation sleeve 3 can freely move up and down, but the gap of spring 4 and stop part 5 and the second through hole 35 can not be excessive, otherwise, installation sleeve 3 can be partial to (namely departing from the axial of installation sleeve 3) in the process of moving up and down, thereby affects effectiveness in vibration suppression.Preferably, the diameter of the second through hole 35 is respectively than the large 2 ~ 5mm of diameter of spring 4 and stop part 5, so both guarantee the matched in clearance of spring 4 and stop part 5 and the second through hole 35, guaranteed again that installation sleeve 3 can not be partial in the process of moving up and down, further guaranteed effectiveness in vibration suppression.
The embodiment of the invention also provides a kind of light fixture (not shown), and it comprises lamp body, lamp holder and foregoing vibration absorber, and the fixed head 31 of this vibration absorber is fixedly connected with lamp body, and mounting disc 1 is fixedly connected with ceiling.Adopt the light fixture of this vibration absorber, when light fixture is subject to vibratory impulse, light fixture can teetertotter, installation sleeve 3 also teetertotters thereupon, spring 4 in the installation sleeve 3 produces certain stroke thereupon, spring 4 utilizes the dilatation of himself that vibrational energy is cut out, thereby realize light fixture is carried out the purpose of vibration damping, the poor parts of shock resistance such as bulb, electric ballast that guaranteed lamp interior can not come off because light fixture is subject to vibratory impulse, guaranteed the normal use of light fixture, the service life of having improved light fixture.
The above is preferred embodiment of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also are considered as protection scope of the present invention.
