Description of drawings
To combine accompanying drawing and embodiment that the present invention is described further below, in the accompanying drawing:
Fig. 1 is the structural representation of the vibration absorber of preferred embodiment of the present invention;
Fig. 2 be among Fig. 1 vibration absorber along the cutaway view of A-A line;
Fig. 3 is the vibration absorber of preferred embodiment of the present invention and the suspension installation diagram of light fixture.
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 as shown in Figure 1, consults Fig. 3 simultaneously, and vibration absorber 100 comprises first holder 10 and second holder 20 that is used to be connected attachment that is used to connect light fixture 200; Also comprise the vibration isolation rubber 30 that is fixedly connected between first holder 10 and second holder 20.Cover 40 in vibration isolation rubber 30 directions interior, said first holder, 10 to second holders 20 in edge are provided with and strengthen.
Vibration absorber 100 is when the multidirectional vibration (as: X-direction, Y direction and Z-direction etc.) that receives from attachment; The second and then vibration of holder 20; The vibration isolation rubber 30 that is fixedly connected between first holder 10 and second holder 20 also can be along with vibrating, but because the elasticity of vibration isolation rubber 30 self, overlap 40 rigidity in combining to strengthen; Can weaken the vibration that is passed to first holder 10, thereby reduce to be connected the vibration of the light fixture 200 on first holder 10.
Vibration absorber 100 among Fig. 1 is as shown in Figure 2 along the cutaway view of A-A line; Consult Fig. 1 and Fig. 3 simultaneously; First holder 10 comprises the first cylindrical body portion 13; And first connecting portion 12 that radially extends along the said first cylindrical body portion 13 1 ends, it is that the center is symmetricly set on first extended surface 12 with the bottom center of first holder 10 that said first connecting portion 12 is provided with a plurality of first locating holes 11 and a plurality of first locating hole 11, in order to vibration absorber 100 is connected on the light fixture 200.
In the present embodiment, in order to make assembling convenient, second holder 20 preferably has identical structure with first holder 10.In order to make connection tightr, the internal diameter size of first holder 10 is suitable with the external diameter size of said vibration isolation rubber 30.
As shown in Figure 3; In the present embodiment; Between the first cylindrical body portion 13 of the lateral wall of vibration isolation rubber 30 and first holder 10; Between the madial wall of the second cylindrical body portion 23 of the lateral wall of vibration isolation rubber 30 and second holder 20, and between the lateral wall of the madial wall of vibration isolation rubber 30 and the interior cover 40 of reinforcement, all adopt the integrated vulcanizing mode to be fixedly connected.Like this can so that vibration isolation rubber 30 with first holder 10, second holder 20 be connected more firm in strengthening between the cover 40.Before sulfuration, on cover 40 lateral walls and the vibration isolation rubber 30, all to use spray fine sand roughening, in the first cylindrical body portion, 13 madial walls, the second cylindrical body portion, 23 madial walls and the reinforcement so that strengthen the cementitiousness of binding agent.After bonding is good, vibration isolation rubber 30 with first holder 10, second holder 20 and the intensity of pullling of overlapping between 40 in strengthening should be greater than 3Mpa, so that resist most vibration environments.
In the present embodiment; Cover 40 preferred employings in the reinforcement of being processed by metal material are overlapped in strengthening; Suitably to reduce vibration isolation rubber 30, reduce the vibration that light fixture 200 produces because of vibration isolation rubber 30 elasticity own along the elasticity on first holder 10 and second holder, 20 closures.The material of preparation vibration isolation rubber 30 can be selected according to different lamps and the working environment used.
In the present embodiment, as shown in Figure 2, be the minimizing material cost, and make the profile of vibration absorber 100 more attractive in appearance that the outer surface of vibration isolation rubber 30 is provided with annular recess 31, sees from cross section shown in Figure 2, is similar to waist shape structure.Because having, vibration isolation rubber 30 set inside strengthen interior cover 40; Therefore though this annular recess 31 makes vibration isolation rubber 30 partial sidewalls attenuation; But can not influence the rigidity of vibration isolation rubber 30 itself; Because the material minimizing is cost-saved, can also make vibration isolation rubber 30 itself become lighter simultaneously, be unlikely to cause excessive burden to lamp installation.
In addition, as shown in Figure 3, consult Fig. 1 simultaneously, the present invention also provides a kind of light fixture 200, the first holders 10 of this vibration absorber 100 that use to be connected on the light fixture 200, and is connected to attachment (not shown) by second holder 20.Can on light fixture 200 and attachment (not shown), respective connecting be set, be connected through screw or other connectors with second locating hole 21 with first locating hole 11 on second holder 20 respectively at first holder 10.
Vibration absorber 100 of the present invention through be provided with in adopting strengthen in the vibration isolation rubber 30 of cover 40 connect and be respectively applied for first holder 10 that is fixedly connected light fixture 200 and be used for fixing second holder 20 that is connected attachment, solve the multidirection antivibration problem of light fixture 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 practice thrift maintenance cost.And damping device structure of the present invention is simple, and production cost is low.
Should be understood that, concerning those of ordinary skills, can improve or conversion, and all these improvement and conversion all should belong to the protection domain of accompanying claims of the present invention according to above-mentioned explanation.
