Description

Technical Field

[0001] This utility model relates to the technical field of prestressed construction in building engineering, and in particular to a steel barcode ruler that can be used under both light and dark conditions. Background Technology

[0002] In the practice of deformation monitoring in civil engineering, building settlement observation often faces the challenge of complex environmental interference. When there are trees, buildings under construction, and temporary construction facilities (such as scaffolding and safety nets) around the observation area, the coupling effect of their spatial layout and sunlight conditions will significantly affect the efficiency of electronic leveling operations. Specifically, some buildings require the establishment of settlement observation points under certain conditions. These settlement observation points are sometimes near trees and buildings under construction. During construction, scaffolding and safety nets are also erected. When surveyors are conducting measurement work, if the trees, buildings under construction, scaffolding, and safety nets are too close to the settlement points, they will create uneven light spots on the surface of the steel barcode ruler under sunlight, causing the electronic level to be unable to read data. Multiple station setups must be performed to avoid the light spots in order to read data normally, reducing work efficiency and increasing workload. Utility Model Content

[0003] The technical problem to be solved by this utility model is: in order to overcome the shortcomings of the existing technology, a steel barcode ruler that can be used under different light spots is provided. When light spots of varying brightness appear on the surface of the steel barcode ruler, the sunshade that is hinged to it is unfolded, and the surface of the steel barcode ruler will form a uniform light and shadow, so that the electronic level can be read normally.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a steel barcode ruler that can be used under both light spots and other conditions, including a steel ruler and a barcode arranged on the steel ruler and used in conjunction with an external electronic level. A sunshade is hinged to one side of the steel ruler via a hinge. When measuring, if no light spot appears on the surface of the steel ruler, the sunshade is retracted; if light spots of varying brightness appear on the surface of the steel ruler, the sunshade is unfolded, at which point a uniform light and shadow is formed on the surface of the steel ruler, so that the external electronic level can be read normally.

[0005] To be further specific, in the above technical solution, the sunshade is composed of several acrylic sheets, and adjacent acrylic sheets are hinged together by hinges.

[0006] The beneficial effects of this utility model are as follows: This utility model provides a steel barcode ruler that can be used under both light and dark conditions. By hinged a sunshade to one side of the steel barcode ruler, the sunshade can be retracted when no light spot appears on the surface of the steel barcode ruler during measurement. If light spots of varying brightness appear on the surface of the steel barcode ruler, the sunshade can be unfolded, and the surface of the steel barcode ruler will form a uniform light and shadow, allowing the electronic level to read normally. This solves the problem of being unable to read measurement values ​​when light spots appear on the surface of the steel barcode ruler, effectively improving work efficiency.

Obviously, the drawings described below are only some embodiments recorded in this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0008] Figure 1 This is a schematic diagram of the structure of this utility model.

[0009] The labels in the picture are: 1. Steel ruler; 2. Barcode; 3. Hinge; 4. Sun visor. Detailed Implementation

[0010] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0011] like Figure 1 As shown, this utility model discloses a steel barcode ruler that can be used under different lighting conditions. It includes a steel ruler 1 and a barcode 2 arranged on the steel ruler 1 and used in conjunction with an external electronic level. A sunshade 4 is hinged to one side of the steel ruler 1 via a hinge 3. The dual-use of this steel barcode ruler is as follows:

[0012] 1. Retract the sunshade 4 and use it in areas without light spots: When measuring, if no light spots appear on the surface of the steel ruler 1, retract the sunshade 4.

[0013] 2. When light spots appear, unfold the sunshade 4 to form a uniform light and shadow, so that the instrument can read normally: When measuring, if light spots of varying brightness appear on the surface of the steel ruler 1, unfold the sunshade 4. At this time, a uniform light and shadow will be formed on the surface of the steel ruler 1, so that the external electronic level can read normally.

[0014] Preferably, the sunshade 4 is composed of several acrylic panels, and adjacent acrylic panels are hinged together by hinges 3. The advantages of this design are:

[0015] ①If light spots of varying brightness appear on the surface of the steel ruler 1, the area of ​​the sunshade 4 can be increased by unfolding several acrylic plates, thereby further increasing the area of ​​light and shadow formed on the surface of the steel ruler 1.

[0016] ②If no light spots appear on the surface of the steel ruler 1, the area of ​​the sunshade 4 can be further reduced by folding several acrylic sheets, making it easier to store.

[0017] Specifically, each acrylic sheet measures 1000mm × 100mm. Adjacent acrylic sheets are hinged together by hinge 3. After several acrylic sheets are spliced ​​together, they are hinged to one side of the steel ruler 1 by hinge 3. The height of the acrylic sheets is 1 meter above the ground.

[0018] This dual-use steel barcode ruler, which can operate under different lighting conditions, has a sunshade 4 hinged to one side of the steel ruler 1. During measurement, if no light spot appears on the surface of the steel ruler 1, the sunshade 4 is retracted; if light spots of varying brightness appear on the surface of the steel ruler 1, the sunshade 4 is unfolded, creating a uniform light and shadow on the surface of the steel ruler 1, allowing the electronic level to read normally. This solves the problem of being unable to read measurement values ​​when light spots appear on the surface of the steel ruler 1, effectively improving work efficiency.

[0019] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
