Building construction illuminating device easy and convenient to use

Abstract

A building construction illuminating device easy and convenient to use comprises a substrate, a rolling and unrolling groove is formed in the substrate, a winding wheel is installed in the rolling andunrolling groove in a steering mode, a taking and placing groove is formed in the left end face of the substrate, a communicating hole is formed between the taking and placing groove and the rollingand unrolling groove, and a power line is arranged on the winding wheel in a wound mode; a midpoint groove extending up and down is formed in the midpoint of the upper end wall of the rolling and unrolling groove, a sliding block is smoothly installed in the midpoint groove up and down, a first installation groove communicating with the midpoint groove is formed in the upper end wall of the midpoint groove, and a first screw hole with an opening part facing the first installation groove is formed in the sliding block; and a first screw is connected with the interior of the first screw hole ina matched mode, the upper end of the first screw is installed in the first installation groove in a steering mode and fixedly provided with a first tooth wheel, a rubber sheet and an inserting springlocated at the midpoint of the rubber sheet are fixedly installed at the lower end of the sliding block, and a pipe sleeve is installed at the midpoint of the end face, facing the sliding block, of the winding wheel.

Description

technical field [0001] The invention relates to the technical field of construction lighting, in particular to an easy-to-use lighting device for building construction. Background technique [0002] In the actual construction of the construction site, due to the tight schedule or construction needs, construction needs to be carried out at night, so the lighting on the construction site has become an indispensable tool in the construction process. However, due to the long power supply connection required in the construction lighting process , making it extremely difficult to take in and out the wires, increasing the workload and reducing work efficiency. At the same time, when not in use, the power supply wires are exposed to the outside world for a long time and are vulnerable to various accidental damages, such as people trampled on, hard objects scratches, etc., resulting in power supply failures.

[0002] In the actual construction of the construction site, due to the tight schedule or construction needs, construction needs to be carried out at night, so the lighting on the construction site has become an indispensable tool in the construction process. However, due to the long power supply connection required in the construction lighting process , making it extremely difficult to take in and out the wires, increasing the workload and reducing work efficiency. At the same time, when not in use, the power supply wires are exposed to the outside world for a long time and are vulnerable to various accidental damages, such as people trampled on, hard objects scratches, etc., resulting in power supply failures. The outer insulation of the line is damaged, resulting in a decrease in the service life of the power supply line. In addition, in some existing construction sites with a relatively long construction period, in order to improve the safety of power supply and lighting, an electric leakage alarm is generally installed on the construction lighting device to achieve However, these alarms are generally exposed and without any protective measures, and are easily damaged by external factors, which brings stability to the use of lighting.
