At present in the illumination field, light fixture, especially precision is than higher lighting, at the harbour, harbour etc. is airborne or carrier-borne etc. when special occasions uses, or in transportation, often continued, strong vibrational excitation, the relatively poor structure of vibration resistance such as bulb, electric ballast of lighting is come off, damage such as fracture, thereby influence the normal use of lighting, bring a lot of troubles and loss to the user.
Therefore, need to adopt vibration absorber to come the lighting of specialty is protected, reducing extraneous impact shock, and prolong the service life of lighting lighting.At present, in the fixed structure of the lighting of specialty, also do not have the supporting vibration absorber that can realize the vibrationproof of dedicated illumination light fixture, do not have the Vibration Absorption Designing standard.At present, more be at certain a light fixture, carry out local Vibration Absorption Designing isolatedly, such as, in lamp socket, add spacing steel wire, so that stop the spinning of bulb in vibration; For another example, adopt elastic support, so that allow lamp casing not be subjected to unexpected thump.Existing Vibration Absorption Designing, shock absorber, specific aim are not strong, do not have the complete vibration damping thinking of a cover.
The utility model content
It is a kind of simple in structure, easy to use that technical problem to be solved in the utility model is to provide, and has the special lamp vibration absorber of good damping property.
The light fixture that provides a kind of damping property good is provided another technical problem to be solved in the utility model.
At above-mentioned vibration absorber, the utility model is achieved like this, and this vibration absorber comprises shell, inner casing and block rubber, and jacket is located at the periphery of inner casing, and is provided with at interval with inner casing, and block rubber adopts the integrated vulcanizing technological forming between shell and inner casing.
Further, described shell and inner casing all are the bowl-shape of upper end open, and it all comprises diapire and sidewall, and each sidewall is extended upward by the edge of corresponding diapire and forms.
Further, have through hole on the diapire of described shell, the internal diameter of through hole is less than or equal to the external diameter of inner casing upper end open.
Further, described block rubber closely contacts with the sidewall of shell and the sidewall of diapire and inner casing.
Further, described shell also comprises roof, and roof is stretched out by the apical margin of sidewall and forms.
Further, offer installing hole on the roof of described shell.
Further, offer connecting hole on the diapire of described inner casing.
Further, the surface that contacts with block rubber of described shell and inner casing is a rough surface.
At above-mentioned light fixture, the utility model is achieved like this, and this light fixture comprises lamp body, support and above-mentioned vibration absorber, and lamp body is rack-mount, and support is installed on the inner casing of vibration absorber.
Compared with prior art, above-mentioned vibration absorber is when work, and vibration is passed on the block rubber by shell, through passing on the inner casing after the block rubber absorbing, passes on the lamp body by support then, and its effectiveness in vibration suppression depends on the vibration absorption ability of block rubber.The block rubber of above-mentioned vibration absorber adopts the integrated vulcanizing technological forming between shell and inner casing, therefore, it can closely contact with shell and inner casing, block rubber no matter be stretch, compression can both consumed energy or shear, and vibrational energy is converted into energy in the friction of rubber molecular chain.Above-mentioned light fixture can significantly improve the antivibration ability, and its vibration absorber can absorb most vibrational energy, reduces the natural frequency of vibration of light fixture integral body, thereby can avoid resonance in most cases, has protected lamp body.

Fig. 1 is the schematic perspective view of a preferred embodiment of vibration absorber in the utility model.
Fig. 2 is the cross-sectional schematic of vibration absorber among Fig. 1.
Fig. 3 is the perspective exploded view of vibration absorber among Fig. 1.
Fig. 4 is the schematic side view of a preferred embodiment of light fixture in the utility model.
The specific embodiment
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Seeing also Fig. 1 to Fig. 3, is a preferred embodiment of vibration absorber in the utility model.This vibration absorber comprises shell 1, inner casing 2 and block rubber 3, and shell 1 covers at the periphery of inner casing 2, and is provided with at interval with inner casing 2, and block rubber 3 adopts the integrated vulcanizing technological forming between shell 1 and inner casing 2.
The material of block rubber 3 can be selected according to different environments for use, and block rubber 3 closely contacts with the sidewall 12 of shell 1 and the sidewall 22 of diapire 11 and inner casing 2.During integrated vulcanizing, shell 1 and inner casing 2 want roughening to handle with the contact-making surface of block rubber 3, so that strengthen the cementitiousness of rubber, coat the binding agent corresponding to the rubber material then on its surface; Shell 1 and inner casing 2 are fixed in mould, then half finished rubber is put well, baking gets final product at a certain temperature.Above-mentioned technology can guarantee that block rubber 3 can closely contact with shell 1 and inner casing 2.
