The technical solution of the utility model is a kind of explosion-proof platform of structure, road, Internal Field Light, it comprises the lamp seat, the lamp housing that are linked in sequence, is located at the bulb on the described lamp seat, also is provided with the vibration absorber that can make described bulb avoid various flutter failures between the lamp socket of described lamp seat and described bulb.

Vibration absorber comprises described in the utility model: be located at described lamp seat front end the lamp socket installing plate, be located at elastic damping circle between this lamp socket installing plate and the described lamp socket front end cylindrical, be located at described lamp socket tail end lamp holder base plate, to be placed in described lamp socket outer and by the shock-absorbing spring of precommpression between described elastic damping circle and described lamp holder base plate.

Wherein, described lamp seat and described lamp housing junction are provided with power-off protection apparatus; but this device comprises the protection bolt that penetrates described lamp housing inner chamber, be located at the boss of described lamp housing inner surface and be connected on this boss can be around the contact seesaw of its tie point swing, be located at two contacts of the conducting main circuit holding wire on the described lamp housing inner surface, the other end that described protection bolt screws a end that its front end of back can compress described contact seesaw, this contact seesaw upwarps and can compress described two contacts simultaneously.

Described protection bolt can cover a ring protection cover plate top be connected in the connector that described lamp seat is connected with described lamp housing.

Be provided with a threaded flame-proof type adapter section between the bar portion of described protection bolt and the described lamp housing.

Because the utility model is provided with the elastic vibration clamper that can make described bulb avoid various flutter failures between the lamp socket of lamp seat and bulb, this structure has been slowed down the vibration and the impact of outer bound pair light fixture electrical appliance effectively, in order to avoid the electrical connection of light fixture is gone wrong and caused potential safety hazard; In addition, increased power outage security for maintenance operation, when needing repairing light fixture, the shell block that turns on the light just can be so that main circuit outage, thereby prevents to cause disaster.

Description of drawings

Below in conjunction with drawings and Examples the utility model is done detailed explanation, wherein:

Fig. 1 is the partial sectional view of the utility model explosion-proof platform, road, Internal Field Light;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 be Fig. 2 C-C to cutaway view;

Fig. 4 be Fig. 2 B-B to cutaway view.

The specific embodiment

Fig. 1 shows the preferred embodiment of the utility model explosion-proof platform, road, Internal Field Light, this explosion-proof platform, road, Internal Field Light comprise the INCREASEDSAFETY explosion-proof wiring assembly 62, lamp seat 3, lamp housing 13, lamp ring 26, the Transparent lamp shade 35 that are linked in sequence, are located at the bulb 50 in the lamp seat 3, for increasing illuminating effect, outside Transparent lamp shade 35, also be provided with a lamp umbrella 63.Between the lamp socket 49 of lamp seat 3 and bulb 50, be provided with and make described bulb 50 avoid the vibration absorber of various flutter failures.

As shown in Figure 3, vibration absorber comprises: screw be connected in described lamp seat front end lamp socket installing plate 48, be located at lamp holder base plate 45 (as shown in Figure 4) that elastic damping circle 47, screw between this lamp socket installing plate 48 and lamp socket 49 front ends 51 cylindricals be connected in described lamp socket 49 tail ends, to be placed in described lamp socket 49 outer and by the shock-absorbing spring 46 of precommpression between elastic damping circle 47 and lamp holder base plate 45.When light fixture is impacted or during the long-term flutter failure of irregular vibration frequency, described elastic damping circle 47, be connected in the lamp holder base plate 45 of described lamp socket 49 tail ends and constituted a buffer cell by the shock-absorbing spring 46 of precommpression between described elastic damping circle 47 and described lamp holder base plate 45, can slow down the destruction of extraneous vibration effectively, thereby avoid producing potential safety hazard for light fixture.
