Construction LED lamp used in emergency

Abstract

The invention belongs to the technical field of LED lamps, and particularly relates to a construction LED lamp used in emergency, which comprises a lifting outer sleeve, a lifting inner rod, a transmission mechanism and the like. The lifting outer sleeve is fixedly arranged on a base. According to the invention, the height of the LED lamp can be freely adjusted according to different requirements in the upper direction and the lower direction; according to a transmission mechanism, when a lifting inner rod is lifted by shaking a crank, as the diameter of a third gear is smaller than the inner diameter of a first circular groove in a second gear, the effect of reducing speed and increasing torque can be achieved, and an operator can easily lift the lifting inner rod by shaking the crank; compared with a traditional lifting mode depending on hydraulic transmission, the production and manufacturing cost is low; and besides, in the height adjusting process of the LED lamp, height adjustment of the LED lamp can be achieved completely by one person, the LED lamp located at the needed height can be automatically positioned, no extra auxiliary limiting device exists, the structure is relatively simple, and operation is easy and convenient.

Description

technical field [0001] The invention belongs to the technical field of LED lamps, in particular to a construction LED lamp used in emergency situations. 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 adjust...

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
