Emergency construction LED lamp

Abstract

The invention belongs to the technical field of LED lamps, and particularly relates to an emergency construction LED lamp. The emergency construction LED lamp comprises a lifting outer sleeve, a lifting inner rod, a transmission mechanism and the like, wherein the lifting outer sleeve is fixedly arranged on a base. The height of the LED lamp emergency construction can be freely adjusted accordingto different demands in the upper direction and the lower direction; when the transmission mechanism lifts the lifting inner rod by moving a crank, the diameter of a third gear is smaller than the inner diameter of a first circular groove in a second gear so that the effects of reducing the speed and increasing the torque can be achieved, and an operator can easily and effortlessly use the crank to lift the lifting inner rod; compared with a traditional lifting mode achieved through hydraulic transmission, the production and manufacturing cost is low; in addition, in the height adjusting process of the LED lamp, the height of the LED lamp can be adjusted completely by one person; the LED lamps located at the required height can be independently positioned without an extra auxiliary limiting device; the structure is relatively simple, and the operation is simple and convenient.

Description

technical field [0001] The invention belongs to the technical field of LED lamps, in particular to an emergency construction LED lamp. Background technique [0002] At present, traditional construction LED lights are widely used in night construction of various engineering sites, and are favored by night construction workers because of their high illumination brightness and wide illumination range. The shapes of construction LED lights commonly used in construction sites are roughly divided into two types: fixed height and adjustable height; for fixed height construction LED lights, the disadvantage is that the height cannot be adjusted according to actual needs during use. The storage after use needs to occupy a lot of space; for the existing height-adjustable construction LED lights, the disadvantage is that the height adjustment of this type of construction LED lights is mainly through hydraulic devices or manual adjustment. To realize its height adjustment, the cost of ...

The shapes of construction LED lights commonly used in construction sites are roughly divided into two types: fixed height and adjustable height; for fixed height construction LED lights, the disadvantage is that the height cannot be adjusted according to actual needs during use. The storage after use needs to occupy a lot of space; for the existing height-adjustable construction LED lights, the disadvantage is that the height adjustment of this type of construction LED lights is mainly through hydraulic devices or manual adjustment. To realize its height adjustment, the cost of the hydraulic device is relatively high, and the artificially adjusted construction LED lamp needs an auxiliary limit device in the process of adjusting the height, which is troublesome to adjust and disassemble, and the adjustment process is laborious; therefore, in This design is a convenient height adjustment and labor-saving construction LED light
