[0018] The utility model is now described in further detail in conjunction with the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0019] Please refer to Figure 1-5 A surveying level ruler that can be used in a dark environment includes a level ruler body 1, which is rectangular and hollow. The level ruler body 1 includes two vertically parallel upright plates 2, a transparent upper panel 3 and a lower panel 4 are provided between the two upright plates 2, a light-emitting mechanism is provided between the upper panel 3 and the lower panel 4, and a scale 31 is provided on the surface of the upper panel 3. After the light-emitting mechanism is operated, light is transmitted through the upper panel 3 and reflected on the scale 31.

[0020] Since the upper panel 3 is transparent, when the internal light-emitting mechanism is in operation, light can pass through the upper panel 3, so that surveying and measurement can be performed even in darkness.

[0021] In the utility model, the light-emitting mechanism includes two light strips 5, one of which is fixed on the bottom surface of the upper panel 3, and the other is fixed on the surface of the lower panel 4. The two light strips 5 are connected to the same power supply, wherein the power supply is a battery, which is arranged inside the rectangular cavity. A USB power interface 23 connected to the light strip 5 is provided on the vertical panel 2. When the power cord is connected to the power supply through the USB power interface 23, the light strip emits light to meet the internal lighting and allow light to pass through.

[0022] Furthermore, a plug-in slot 22 is provided on the inner side of the vertical plate 2, and the upper panel 3 and the lower panel 4 are pluggably connected to the two vertical plates 2 through the plug-in slot 22. Side panels 6 are provided at both ends of the level ruler body 1, and the side panels 6 are detachably connected to the vertical plates 2, so that the whole can be easily installed and disassembled, and can be replaced separately when partially damaged, thereby increasing the overall practicality.

[0023] The ends of the upper panel 3 and the lower panel 4 protrude from the side wall of the vertical panel, the inner surface of the side panel 6 is provided with a limiting groove 63 that cooperates with the upper panel 3 and the lower panel 4, the surface of the side panel 6 is provided with a heat dissipation groove 62, and bolts 61 are provided on both sides of the heat dissipation groove 62, and the side surface of the vertical panel 2 is provided with a mounting hole 21 corresponding to the bolt 61.

[0024] When the upper panel 3 and the lower panel 4 are inserted between the two vertical panels 2, the side panel 6 is installed. When the side panel 6 is connected to the vertical panel 2 by bolts 61, the limit groove 63 corresponds to the upper panel 3 and the lower panel 4, so that the vertical panel 2, the upper panel 3, the lower panel 4 and the side panel 6 are interconnected and fixed.

[0025] In order to improve the measurement accuracy of the level rod, a fixing ring 41 is further provided on the bottom surface of the lower panel 4. A transparent sealing tube 42 is provided in the fixing ring 41. The sealing tube 42 is provided with fluorescent liquid, and the volume of the fluorescent liquid is 1 / 2 of the volume of the sealing tube.

[0026] That is, the sealing tube 42 is provided with fluorescent liquid. When the measuring ruler is measured vertically, the liquid surface of the fluorescent liquid in the sealing tube 42 is horizontal. When the measuring ruler is tilted, the internal fluorescent liquid tilts to one side, and the surface of the measuring ruler is not vertical.

[0027] When in use, the liquid level of the fluorescent liquid can be observed to determine whether the measuring ruler is in a vertical state, thereby improving the measurement accuracy; this principle is similar to that of a spirit level, which will not be elaborated on.

[0028] The fluorescent liquid emits light in the dark and can also be used at night.

[0029] In this embodiment, the upper panel 3 is made of transparent rubber resin, acrylic, etc., which has good light transmittance and ensures that the scale is clearly visible.

[0030] Based on the above embodiment, the end of the vertical plate 2 can also be set to a vertical plane so that the side plate 6 is perpendicular to the vertical plate.

[0031] Based on the above embodiment, the sealing tube 42 on the back of the lower panel 4 can also be replaced by a luminous circular level, which can detect deviations in four directions and further increase the measurement accuracy.

[0032] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
