The specific embodiment
Below in conjunction with diagram, the preferred embodiments of the present invention are described in detail.
The vibration absorber 100 stereochemical structures signal of preferred embodiment of the present invention is consulted Fig. 4 as shown in Figure 1 simultaneously, and described vibration absorber 100 comprises the upper casing 11 and lower casing 12 that is interlocked and connects to form vibration damping housing 10.Described vibration damping housing 10 is provided with the securing member 30 that is used to connect attachment 300.In vibration damping housing 10, be provided with connecting rod 20, first vibration isolation rubber 40 and second vibration isolation rubber 50, and between first vibration isolation rubber 40 and second vibration isolation rubber 50 and be fixedly connected on limiting plate 21 on the connecting rod 20.
Vibration absorber 100 among Fig. 1 along the echelon sectional view of B-B line as shown in Figure 3, is consulted Fig. 4 and Fig. 5 along the echelon sectional view of A-A line as shown in Figure 2 simultaneously, in vibration damping housing 10, be provided with connecting rod 20, the upper end of connecting rod 20 passes upper casing 11, is used to connect the vibrationproof product, as light fixture 200.Be positioned at connecting rod 20 on the part of vibration damping housing 10 and be arranged with first vibration isolation rubber 40, connecting rod 20 lower ends are set with the limiting plate 21 that supports first vibration isolation rubber 40, below limiting plate 21, be provided with second vibration isolation rubber 50 that is positioned at vibration damping housing 10, described second vibration isolation rubber 50 is provided with the stopper slot 51 that is used to hold described limiting plate 21, and limiting plate 21 can be snapped between described first vibration isolation rubber 40 and second vibration isolation rubber 50.
Vibration absorber 100 is when the multidirectional vibration that is subjected to from attachment 300, first vibration isolation rubber 40 and second vibration isolation rubber 50 can be sheared according to the direction of vibration force, compression, vibration is reduced the back be delivered on the light fixture 200, therefore can slow down the vibratory impulse power in the light fixture 200 suffered external worlds by limiting plate 21 and connecting rod 20.
The blast structural representation of the vibration absorber 100 of present embodiment as shown in Figure 4, consult Fig. 1, Fig. 2, Fig. 3 and Fig. 5 simultaneously, securing member 30 comprises bolt 31 and corresponding nut 32, bolt 31 passes upper casing 11 and lower casing 12 successively, by nut 32 lockings that are positioned at bolt 31 ends, so that upper casing 11 and lower casing 12 are fixedly connected to form vibration damping housing 10, and connecting rod 20, first vibration isolation rubber 40 and second vibration isolation rubber 50 be pressed between upper casing 11 and the lower casing 12, the limiting plate 21 of connecting rod 20 lower ends is positioned at stopper slot 51.Securing member 30 not only is used for the vibrationproof product, as light fixture 200, is connected on the attachment, be used for simultaneously upper casing 11 is fixedlyed connected with lower casing 12, can reduce the amount of parts of vibration absorber 100, make vibration absorber 100 structures simpler, can also save cost simultaneously.
As shown in Figure 4, preferably first vibration isolation rubber 40 and second vibration isolation rubber 50 are set to same structure, promptly on first vibration isolation rubber 40, also are provided with stopper slot 51; And upper casing 11 and lower casing 12 be set to same structure, and can distinguish during assembling, make each parts assembling process of vibration absorber 100 simpler.Wherein, first vibration isolation rubber 40 and second vibration isolation rubber 50 preferably are set to annular, and the size shape in its annular center hole and described connecting rod 20 are suitable.
Because first vibration isolation rubber 40 and second vibration isolation rubber 50 have certain elasticity, when upper casing 11 and lower casing 12 fasten first vibration isolation rubber 40 that compresses wherein and second vibration isolation rubber 50, limiting plate 21 snaps onto in the stopper slot 51 of first vibration isolation rubber 40 and second vibration isolation rubber 50, when vibration absorber 100 is subjected to impulsive force or vibration, first vibration isolation rubber 40 and second vibration isolation rubber 50 are sheared, compression, after absorption of vibrations reduced, be delivered on the light fixture 200 by connecting rod 20.
As shown in Figure 4, limiting plate 21 preferably is set to cross, consistent and stopper slot 51 the aperture with limiting plate 21 shapes of the shape of stopper slot 51 is bigger, so that when first vibration isolation rubber 40 and second vibration isolation rubber 50 compress, limiting plate 21 can fit snugly between the two, reduces vibration with better absorption.
Adopt criss-cross limiting plate 21 can be better to a plurality of direction transmission from multidirectional vibration force, make that first vibration isolation rubber 40 and second vibration isolation rubber 50 take place to shear accordingly, compression.And criss-cross limiting plate 21 can make light fixture 200 can not take place circumferentially to rotate under the vibration effect, connects more stable.
In addition, as shown in Figure 5, consult Fig. 1 simultaneously, the present invention also provides a kind of light fixture 200 that uses this vibration absorber 100, an end that is stretched out upper casing 11 by connecting rod 20 is connected on the light fixture 200, and is connected to attachment 300 by the securing member 30 of fixedly connected upper casing 11 and lower casing 12.Because vibration absorber of the present invention is 100 simple in structure, volume is less, can use separately when installing with light fixture 200, also can a plurality ofly use together.
Vibration absorber 100 of the present invention will be subjected to multidirectional vibration from attachment 300 by first vibration isolation rubber 40 and second vibration isolation rubber 50 and absorb and weaken, and be passed to light fixture 200 by connecting rod 20 again, can solve the multidirection antivibration problem of light fixture 200 effectively.
The vibration absorber 100 of the application of the invention can significantly improve the resistance to shock of light fixture 200, improves the service life of light fixture bulb, thereby has avoided the client because of bulb damages the economic loss of bringing, and can save maintenance cost.And damping device structure of the present invention is simple, and production cost is low.
Should be understood that, for those of ordinary skills, can be improved according to the above description or conversion, and all these improvement and conversion all should belong to the protection domain of claims of the present invention.
