On light fixture fixation steel plate 4,5 points of the protective cover is upper and lower two parts, and is bolted on fixed galvanized steel bottom respectively
On plate 1, the protective cover 5 opens rectangle hole in centre, and the lamp installation hole on light fixture fixation steel plate 4 is exposed.
Further, limit damping spring 3 described in four groups is in extended state in normal state, and parallel to solid
Balance is kept on the direction of fixed zinc-plated steel sole plate 1.
Further, the supporting damping spring 2 in normal operation be in compressive state, and with four groups of spacing resistances
Buddhist nun's spring 3 is together maintained at the force balance on the direction of fixed zinc-plated steel sole plate 1.
Further, the length and width size of the rectangle square hole is less than the length and width size of light fixture fixation steel plate 4, more than light fixture branch
The length and width size of frame.
Compared with prior art, the beneficial effects of the utility model are：
Using the utility model, illuminator can be both firmly installed in the tunnel wall of running tunnel, again can be with
Ensure that illuminator can be moved freely in certain allowed band, reduce under external force effect, between whole device and tunnel wall
The active force that fixed expansion bolt is born, and suitable for different types of illuminator, standardization can be achieved and installs, operation
Simply, it is easy to maintenance, reduce light fixture and come off probability, engineering construction effect is very good.

Embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As illustrated, a kind of be applied to lamp base of the tunnel with damping unit, including fixed zinc-plated steel sole plate 1, support
Damping spring 2, limit damping spring 3, light fixture fixation steel plate 4 and protective cover 5, fixed zinc-plated steel sole plate 1 pass through four groups of expanding screws
Bolt is fixed in tunnel wall, and the two ends of supporting damping spring 2 and limit damping spring 3 are separately fixed at fixed zinc-plated steel sole plate 1
On the connection terminal of light fixture fixation steel plate 4, tunnel illumination light fixture is arranged on light fixture fixation steel plate 4 by bolt, protective cover 5
It is divided into upper and lower two parts, and is bolted on respectively on fixed zinc-plated steel sole plate 1, protective cover 5 opens rectangular opening in centre
Hole, the lamp installation hole on light fixture fixation steel plate 4 is exposed.
Four groups of limit damping springs 3 are in extended state in normal state, and parallel to fixed zinc-plated steel sole plate 1
Direction on keep balance.
Supporting damping spring 2 is in compressive state in normal operation, and is together protected with four groups of limit damping springs 3
Hold the force balance on the direction perpendicular to fixed zinc-plated steel sole plate 1.
The length and width size of rectangle hole is less than the length and width size of light fixture fixation steel plate 4, more than the length and width size of lamp bracket.
As shown in figs 1 to 6, fixed zinc-plated steel sole plate 1 is fixed in tunnel wall by four groups of expansion bolts；Fixation is zinc-plated
There is the fixing terminal of supporting damping spring 2 and limit damping spring 3 on steel sole plate 1 respectively, will can be supported by this fixing terminal
