AI Technical Summary
During the measurement process, poor light at the measurement point causes the level to be unable to read the readings of the indium steel level ruler clearly, requiring additional personnel lighting, affecting the accuracy of the reading.
Install the LED lamp band on the ruler surface of the Ganggang Rukia, which provides a self -illuming function to ensure that the reading is still clearly visible in the case of poor light.
Through the self -illuming function, the measurement error caused by insufficient light is avoided, the accuracy and reliability of measurement can be ensured, and normal measurement can be performed at night or insufficient light.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of level measurement and relates to an indium steel level ruler with a self-illumination function. Background Art
[0002] Leveling is a method of measuring the height difference between two points on the ground using a level and a level rod. A level is placed between two points on the ground, and the level rod erected at the two points is observed. The height difference between the two points is calculated based on the readings on the rod.
[0003] Indium steel ruler is a kind of level ruler, which uses an indium steel strip fixed in the ruler frame as the matrix for marking readings. Since indium steel has a small thermal expansion coefficient and high marking accuracy, it is the first choice for precision leveling measurement. However, during the measurement process, sometimes the light at the measuring point is poor, and the level ruler reading cannot be seen clearly through the level telescope. In the above situation, one person usually holds the ruler and one person illuminates the level ruler. This not only increases the number of people, but also artificial lighting cannot guarantee the stability of the light source. Due to uneven lighting, it will affect the accuracy of the reading. Summary of the invention
[0004] The utility model aims to solve the above problems and provide an indium steel level with a self-illumination function to avoid the measurement work being affected by the poor light conditions at the measuring point.
[0005] The technical solution of the utility model is as follows:
[0006] An indium steel level ruler with a self-illuminating function comprises a ruler body, a top cover is provided on the upper fixed sleeve of the ruler body, a bottom foot is provided on the lower fixed sleeve, and a scale line is provided in the middle of the ruler surface of the ruler body along the longitudinal direction. The invention is characterized in that: an LED light strip is provided in the longitudinal direction on both sides of the scale line on the ruler surface of the ruler body, the back side of the LED light strip is bonded to the ruler surface, a battery box is provided on the bottom foot, dry batteries are installed in the battery box, and the dry batteries are electrically connected to the power line of the LED light strip.
[0007] The utility model installs LED light strips on both sides of the indium steel ruler engraved readings, so that the level ruler has a self-illumination function. When the light at the measuring point is poor, the bar code of the indium steel ruler is still clearly visible. With the utility model, normal measurement work can be carried out even at night, and the measurement accuracy can be guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] like Figure 1 , Figure 2 , Figure 3 As shown, the utility model includes a ruler body 1, a top cover 2 is fixedly sleeved on the upper end of the ruler body, a bottom foot 3 is fixedly sleeved on the lower end, and a scale line 4 is longitudinally provided in the middle of the ruler surface of the ruler body; an LED light strip 5 is longitudinally provided on both sides of the scale line 4 on the ruler surface of the ruler body, and the back of the LED light strip 5 is bonded to the ruler surface, a battery box 6 is provided on the bottom foot 3, and dry batteries 7 are installed in the battery box 6, and the dry batteries 7 are electrically connected to the power line of the LED light strip 5.
[0014] The above structure is provided with a power switch on the battery box to control the on-off of the dry battery and the power line of the LEGD light strip. The power is turned on as needed, and the LED light strip illuminates the scale of the ruler.
[0015] Furthermore, a rechargeable battery cavity 8 can be provided on one side of the ruler body, a rechargeable battery is provided in the rechargeable battery cavity, the rechargeable battery is electrically connected to the power line of the LED light strip, and a USB socket 9 for charging the rechargeable battery is provided on the outside of the rechargeable battery cavity. A power switch is provided on the outside of the rechargeable battery cavity, and the rechargeable battery is used as a backup power source. When the dry battery is insufficient, the LED light strip is powered by the rechargeable battery.
[0016] When the utility model is implemented, in order to protect the LED light strip and prevent the light from directly shining on the level operator, a cover plate 10 is provided on the ruler body on one side of the scale and the LED light strip, and the upper and lower ends of the cover plate 10 are respectively fixed in the top cover 2 and the bottom foot 3. The part of the cover plate 10 facing the scale line is completely transparent, and the remaining parts are set to be translucent or opaque.
[0017] like Figure 3 , Figure 4 , Figure 5 As shown, in order to prevent gaps between the two sides of the cover plate 10 and the ruler surface of the ruler body and to ensure that the cover plate is firmly installed, cover plate slots 11 are longitudinally provided on both sides of the ruler surface of the ruler body, and the cross-section of the cover plate slot is C-shaped, and the width of the slot is smaller than the width inside the slot; plugs 101 with T-shaped cross-sections are provided on both sides of the cover plate 10, and the plugs 101 on both sides of the cover plate are respectively stuck in the cover plate slots on the ruler body.
