Description

Technical Field

[0001] The utility model belongs to the technical field of surveying and mapping devices and relates to a day and night dual-purpose bar code leveling rod. Background Art

[0002] Electronic levels have been widely used in the fields of architecture, civil engineering and surveying engineering. They can accurately measure the height difference between ground points and provide important basic data for engineering design and construction. Existing electronic levels measure by scanning the barcode leveling scale to read the readings. Electronic levels do not have the function of high beam illumination. Standard, unmodified original barcode leveling scales also do not have the lighting function and no fill light device. Leveling is not only done during the day with sufficient light, but also often requires observation at night or in tunnels. In the case of insufficient light or no light, the electronic level cannot scan the code to read the readings and cannot be measured. Usually, auxiliary personnel are required to illuminate the scale with high beams for readings. This method has three disadvantages. First, the auxiliary personnel generate labor costs, which increases the cost of surveying and mapping. Second, the light source irradiates the scale to produce light and dark areas, the light source is uneven, and the accuracy is reduced. Third, the light source irradiates the scale to produce shading differences, which affects the accuracy.

[0003] In addition, auxiliary lighting equipment is added to the existing bar code leveling scales, some of which have too many accessories and are complicated and cumbersome; some are lacking in practicality; and some are not conducive to mass production. Utility Model Content

[0004] The utility model aims to provide a day and night dual-purpose bar code leveling rod, which has the characteristics of high precision of leveling measurement at night and in tunnels.

[0005] The technical scheme adopted by the utility model is a day and night dual-purpose barcode level ruler, comprising a ruler body, a ruler groove is opened in the middle of the front side of the ruler body, a barcode ruler belt is installed in the ruler groove, LED light belts are installed on the inner walls of both sides of the ruler groove, and a circular level is arranged in the middle of the back side of the ruler body.

[0006] The utility model is also characterized in that:

[0007] A pair of telescopic slide rails are respectively installed at both ends of the ruler groove, and each pair of telescopic slide rails is slidably connected with a telescopic sliding block.

[0008] A limit screw is installed at the bottom of the telescopic sliding block.

[0009] The telescopic slider is fixedly connected with a plurality of tape fixing springs, and each tape fixing spring is also fixedly connected with a barcode tape.

[0010] A lithium battery compartment is provided inside the ruler body, and the lithium battery compartment is connected to the LED light strip through a wire.

[0011] The beneficial effects of the utility model are: reducing the number of operating personnel, lowering production costs, ensuring the accuracy of leveling measurements at night and in tunnels, and the new scale is not difficult to manufacture and can be mass-produced. After the scale is produced, it is suitable for barcode tapes of different models. BRIEF DESCRIPTION OF THE DRAWINGS
