Lamp and face cover rotation preventing structure thereof

Abstract

The invention relates to the technical field of lamps and provides a lamp and a face cover rotation preventing structure thereof. The face cover rotation preventing structure is arranged between a lamp shell and a face cover, in mutually-rotary buckling, of the lighting lamp and comprises a stepped hole formed in the lamp shell, a positioning hole formed in the face cover and an elastic positioning component penetratingly arranged in the stepped hole, the bottom end of the elastic positioning component extends in the positioning hole while the top end of the same extends out of a top opening of the stepped hole, and when pulled by an external force, a clamping and stopping member capable of driving the elastic positioning component to elastically retract to enable the bottom end to retreat from the positioning hole is arranged at the top end of the elastic positioning component. When no external force action, the elastic positioning member is sequentially and penetratingly arranged in the stepped hole in the lamp shell and the positioning hole of the face cover, so that mutual rotation of the lamp shell and the face cover is prevented, and the face cover is prevented from rotating and shedding from the lamp shell in a vibrating environment; when the clamping and stopping member is pulled by the external force, the elastic positioning component elastically retracts, the bottom of the elastic positioning component retreats from the positioning hole of the face cover, and at this time, the face cover and the lamp shell can be demounted and separated only by oppositely screwing the face cover and the lamp shell.

Description

technical field [0001] The invention relates to the technical field of lighting, and more specifically relates to a lamp and a surface cover anti-rotation structure of the lamp. Background technique [0002] At present, the general tubular lamps are installed with a rotating fastening structure between the lamp housing and the cover. Although this structure is easy to disassemble and assemble, the stability of the installation is poor, and its safety level is only applicable to general occasions. It is not suitable for some places with strong vibration, such as open mountains or oil fields. If this kind of rotating fastening lamp is used in these special occasions, the lamp housing and the cover will rotate and become loose under the vibration environment, so that the cover will be detached from the lamp housing, which will not only cause damage to the lamp, but may also affect the scene.

Problems solved by technology

[0002] At present, the general tubular lamps are installed with a rotating fastening structure between the lamp housing and the cover. Although this structure is easy to disassemble and assemble, the stability of the installation is poor, and its safety level is only applicable to general occasions. Not suitable for some strong vibration occasions, such as open mountains or oil fields, etc.

If this kind of rotating fastening lamp is used in these special occasions, the lamp housing and the cover will rotate and become loose under the vibration environment, so that the cover will be detached from the lamp housing, which will not only cause damage to the lamp, but may also affect the scene.
