Explosion-proof fluorescent lamp

Abstract

The invention relates to an explosion-proof fluorescent lamp comprising a lamp box, a transparent module, a tube and a lamp holder module. The transparent module is fastened with the lamp box to forma sealing cavity. The tube is arranged in the sealing cavity and the lamp holder module is used for fixing an electrode holder and realizing electric connection. The lamp holder module comprises a lamp holder housing provided with a clip hole and a lamp cap holder which is sleeve-connected in the clip hole and rotates relative to the lamp holder housing. The lamp holder housing is provided with afirst bayonet and the lamp cap holder is provided with a second bayonet. The lamp cap holder rotates relative to the lamp holder housing to drive the second bayonet and the first bayonet to be alignedwith each other to form a channel or to be staggered. In the explosion-proof fluorescent lamp, the lamp cap holder capable of rotating relative to the lamp holder housing is arranged on the lamp holder module, and a wedge-shaped notch arranged on the lamp cap holder is adaptive to and clip-connected with a wedge-shaped column arranged on the lamp holder housing to prevent relative rotation between the lamp cap holder and the lamp holder housing, thus avoiding separation of the tube from the lamp holder module and enabling the tube to be fixed with the lamp holder firmly so as to ensure stablecontact between the electrode of the tube and the conductive electrode plate of the lamp holder and ensure normal use of the fluorescent lamp.

Description

technical field [0001] The present invention relates to a lamp, and more specifically relates to an explosion-proof fluorescent lamp. Background technique [0002] In the existing explosion-proof fluorescent lamps, the electrode of the lamp tube and the lamp holder are connected vertically to the ground by in-line clamping, that is, the electrode of the lamp tube is clamped by the elastic restoring force of the elastic conductive electrode sheet arranged on the lamp holder. However, in this clamping method of the explosion-proof fluorescent lamp tube, since there is no anti-off structure between the electrode of the lamp tube and the conductive electrode sheet of the lamp holder, when the explosion-proof fluorescent lamp is subjected to external vibration, the electrodes of the lamp tube and the conductive electrode sheet of the lamp holder will be separated. Collapse or detachment occurs, causing the fluorescent lamp to go out non-destructively and abnormally, thereby incre...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a method for fixing the lamp tube and the lamp holder in view of the defects in the prior art that the above-mentioned lamp tube and lamp holder fixing method is not firm and easily makes the contact between the lamp tube electrode and the lamp holder conductive electrode sheet unstable. Explosion-proof fluorescent lamps that firmly make the electrodes of the lamp tube and the conductive electrodes of the lamp holder contact stably
