Lamp base structure of fluorescent lamp

Abstract

The invention relates to a lamp base structure of a fluorescent lamp, which comprises a lamp base, a lamp holder socket and a rotary sleeve, wherein the lamp holder socket is fixedly arranged on the lamp base, and the rotary sleeve is rotatably sleeved on the lamp holder socket. A first bayonet is arranged on the rotary sleeve, a second bayonet is arranged on the lamp holder socket, and the rotary sleeve rotates relative to the lamp holder socket and drives the first bayonet and the second bayonet to be aligned and to form a channel or be staggered. The lamp holder socket is fixed onto the lamp base, an electrode and an electric wire are fixed onto lamp base pins, and the lamp base pins, the electrode or the electric wire cannot be driven to rotate by means of rotation of the rotary sleeve when a fluorescent lamp tube is mounted, so that the electric wire is effectively prevented from being locked or jammed, and the service life of the lamp base is prolonged. The rotating angle of the rotary sleeve is not limited, and the fluorescent lamp tube is simple and convenient in mounting process and easy in operation.

Description

technical field [0001] The invention relates to a lighting fixture, more specifically, to a lamp holder structure of an increased safety explosion-proof fluorescent lamp. Background technique [0002] There are two requirements for lamp holders of safety-increased explosion-proof lamps: (1) There is only one electrode at a single end, and the fluorescent tube cannot preheat the filament when it is started, and it is directly cold-started; (2) The electrode of the lamp holder cannot use a shrapnel structure, shrapnel The structure of the lamp holder will generate electric sparks when it vibrates. In the prior art, the structure of the lamp holder of the fluorescent lamp is mostly used for civilian lamps, and many lamp holders cannot meet the use requirements of the increased safety explosion-proof lamps. At present, the main defect of the lamp holders that meet the increased safety explosion-proof lamps is that these lamp holders are internally rotated, and when the lamp tub...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a lamp holder structure for fluorescent lamps that can solve the above problems well in view of the defects that the wires in the lamp holder of the fluorescent lamp are easily stuck and the rotation angle of the lamp holder is limited in the prior art.
