Description

Technical Field

[0001] The utility model relates to the technical field of indium steel rulers for building construction measurement, in particular to a nighttime lighting device based on a precision level indium steel ruler. Background Art

[0002] Indium steel ruler is a kind of leveling ruler. Because of its small expansion coefficient, indium steel ruler has higher accuracy than general leveling ruler. When measuring settlement, some engineering projects need to measure settlement at night or in low light conditions. At this time, it is necessary to rely on manual flashlight to supplement the light for the indium steel ruler so that the instrument can read the data. This method requires one person to measure and one person to hold the ruler, which makes night measurement more difficult and wastes manpower; another way is to stick a light strip on the edge of the indium steel ruler and connect the light strip to charge with a power bank. This method requires the ruler holder to hold the power bank in one hand and the ruler in the other hand, so it is easy to cause errors in the measurement work. The invention patent with application number 202310274775.7 discloses an indium steel ruler, which includes an indium steel ruler main body, a fixing component arranged on the outside of the indium steel ruler main body, and a fill light device for filling light to the indium steel ruler main body at night is connected to one side of the fixing component; the fixing component includes two mounting plates installed on the ground, the distance between the two mounting plates is equal to the width of the indium steel ruler main body, and the inner side of the mounting plate is connected to a limit plate for limiting the position of the indium steel ruler main body; the fill light device includes two focusing frames connected to one side of the two mounting plates, the cross-section of the focusing frame is C-shaped, and a space for light placement is formed between the two focusing frames, and a placement component for placing a light bar is arranged in the focusing frame, which can improve the reading accuracy and efficiency of the indium steel ruler while ensuring lighting, but the device has a relatively complex structure, a long installation time, and poor practicality.
