Description

Technical Field

[0001] This utility model belongs to the technical field of building inspection devices, specifically relating to an indium steel ruler that can reduce the influence of light and shadow during measurement. Background Technology

[0002] In building settlement monitoring, various obstructions cause dappled light and shadow on the barcode surface of the indium steel measuring tape under sunlight, affecting laser reflection and making the level instrument unreadable. Currently, the main methods to reduce the impact are rotating the measuring tape or having the person holding the tape block the light with their body, which reduces work efficiency and cannot completely eliminate the impact.

[0003] In view of this, it is necessary to provide a device that can block ambient light to a certain extent and reduce environmental interference with the observation of indium steel rulers. Summary of the Invention

[0004] In view of the above-mentioned defects in the prior art, the present invention aims to provide an indium steel ruler that can reduce the influence of light shadows during measurement, so as to effectively avoid the influence of ambient light on the detection in building settlement observation.

[0005] To address the aforementioned technical problems, this utility model discloses an indium steel ruler that can reduce the influence of light and shadow during measurement. The ruler includes an indium steel ruler body and folding plates disposed on both sides of the indium steel ruler body. Each folding plate is composed of several single plates with a width not exceeding the thickness of the indium steel ruler body. Each single plate includes a connecting single plate and at least one light-shielding single plate connected sequentially in a hinged manner. The connecting single plate is fixed to the side of the indium steel ruler body, and the light-shielding single plate adjacent to the connecting single plate is connected to the side of the connecting single plate near the indium steel ruler's scale surface. When the folding plates on both sides of the indium steel ruler body are unfolded, the blocking surface formed by the light-shielding single plate blocks ambient light, thereby reducing the interference of ambient light on observation.

[0006] Preferably, the connecting plate is fixed to the side of the indium steel ruler body by adhesive backing or fasteners.

[0007] Preferably, the indium steel ruler body has a magnet on its side, and the light-shielding plate has a ferromagnetic metal at the position corresponding to the magnet.

[0008] Preferably, the width of the light-shielding panel is the same as the thickness of the indium steel ruler body.

[0009] Preferably, the number of light-shielding panels is 1-3.

[0010] Preferably, the number of the light-shielding panels is one.

[0011] Preferably, the height of the light-shielding panel is not greater than the height of the invar steel ruler body.

[0012] Preferably, the height of the light-shielding panel is the same as the height of the indium steel ruler body.

[0013] This invention relates to an indium steel ruler that reduces the influence of light and shadow during measurement. By using folding plates on both sides of the indium steel ruler body to block ambient light, it effectively avoids the problem of light and shadow dappling the barcode surface of the indium steel ruler in shady places, which affects laser reflection and causes the level instrument to be unable to read the data. The folding plates can be easily stored when not in use, and when unfolded, the influence of light and shadow on the indium steel ruler reading is reduced, significantly improving observation efficiency and accuracy.

[0018] The present invention will be further described in detail below through embodiments, so that those skilled in the art can implement it based on the description.

[0019] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0020] like Figure 1-2 As shown, an indium steel ruler capable of reducing the influence of light and shadow during measurement includes an indium steel ruler body and folding plates disposed on both sides of the indium steel ruler body. Each folding plate is composed of several single plates with a width not greater than the thickness of the indium steel ruler body. Each single plate includes a connecting single plate 3 and at least one light-shielding single plate 4 connected in a folded form. The connecting single plate is fixed to the side of the indium steel ruler body, and the light-shielding single plate adjacent to the connecting single plate is connected to the side of the connecting single plate near the indium steel ruler scale surface. When the folding plates on both sides of the indium steel ruler body are unfolded, the blocking surface formed by the light-shielding single plate blocks the ambient light, thereby reducing the interference of ambient light on the observation.

[0021] The connecting plate is fixed to the side of the indium steel ruler body by adhesive backing 5 or fasteners (such as screws).

[0022] The width of the light-shielding panel is the same as the thickness of the invar steel ruler body. The number of light-shielding panels is 1-3. The height of the light-shielding panel is no greater than the height of the invar steel ruler body. In this embodiment, the folding plate is adhered to the side of the invar steel ruler using waterproof double-sided adhesive. The folding plate is made of ABS resin, with an unfolded size of 8cm*180cm and a folded size of 4cm*180cm, offering flexible and convenient folding with good stability. Example

[0023] like Figure 3 As shown, similar to Embodiment 1, the difference lies in that the indium steel ruler body has a magnet 6 on its side, and a ferromagnetic metal 7 is provided on the light-shielding panel at the corresponding position. This makes the folding panel less likely to unfold when stored, and very convenient to unfold. In this embodiment, magnets are provided on the upper and middle parts of the side of the steel ruler body, and ferromagnetic metal is provided on the light-shielding panel at the corresponding position; note that magnets should not be placed on the light-shielding panel to avoid the problem of the two sides of the light-shielding panel sticking together after the light-shielding panel is opened.

[0024] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and embodiments shown and described herein.
