Abstract
Description
Technical Field
[0001] This utility model belongs to the field of highway design technology, and in particular relates to a highway slope measuring instrument. Background Technology
[0002] Currently, slope measurement for highway design is mostly done using slope meters. When using slope meters to measure slope, dirt on the slope surface may stick to the measuring surface of the slope meter. Particles and other substances in the dirt may rub against the measuring surface during use, accelerating the wear of the measuring surface. Wear on the measuring surface of the slope meter will affect the accuracy of the measurement. Therefore, a highway slope measuring instrument is needed that can replace and fix the measuring surface of the slope meter through a clamping structure to avoid the worn measuring surface affecting the measurement results and ensure the accuracy of the slope meter measurement. Utility Model Content

Limiting blocks are fixedly connected to the top and bottom of the inner cavity of the slide groove. A slider is slidably connected to the inner cavity of the slide groove. Limiting grooves are formed at the top and bottom of the slider. The limiting blocks are adapted to the limiting grooves. The slider is in contact with the side of the detachable measuring panel away from the limiting components. Two symmetrical fixing rods are fixedly connected to the inner cavity of the slide groove. The fixing rods pass through the slider and are slidably connected to the slider. Springs are sleeved on the surface of the two fixing rods. One end of the spring is fixedly connected to the slider, and the other end of the spring is fixedly connected to the inner wall of the slide groove. A lever is fixedly connected to the side of the slider away from the measuring instrument body.

[0006] Preferably, the guide rail has a T-shaped cross-section, and the side of the guide rail away from the limiting member is in contact with the side of the slider that is close to the measuring instrument body.
[0007] Preferably, the corners of the limiting member are rounded, the cross-section of the slider is H-shaped, and the top and bottom of the slider are respectively fitted to the top and bottom of the inner cavity of the groove.
[0008] Preferably, the side of the lever closest to the measuring instrument body is in contact with the measuring instrument body, and the side of the lever furthest from the measuring instrument body is fixedly connected with multiple longitudinal anti-slip strips.
[0009] The beneficial effects of this utility model are:
[0010] 1. This utility model allows the slider to slide towards the square spring by moving the lever, causing the spring to be compressed and contracted.

[0021] Figure 1-4This invention illustrates a highway slope measuring instrument according to an embodiment of the present invention. It includes a measuring instrument body 1, a scale 2 extending through the top of the measuring instrument body 1, a level tube 3 rotatably connected to the inner cavity of the scale 2, a scale rotating wheel 4 rotatably connected to the top of the measuring instrument body 1, guide rails 5 fixedly connected to both the front and back of the measuring instrument body 1, detachable measuring panels 6 slidably connected to the surface of the guide rails 5, a limiting member 7 fixedly connected to the front of the measuring instrument body 1 with rounded corners, a slider 10 with an H-shaped cross-section, the top and bottom of the slider 10 respectively fitting into the top and bottom of the inner cavity of a groove 8, and both detachable measuring panels 6 fitting into the limiting member 7. Grooves 8 are provided on the right side and back of the measuring instrument body 1, and limiting members 8 are fixedly connected to the top and bottom of the inner cavities of both grooves 8. The inner cavity of the positioning block 9 and the slide groove 8 is slidably connected to a slider 10. The top and bottom of the slider 10 are provided with limiting grooves 11. The limiting block 9 is adapted to the limiting grooves 11. The slider 10 is in contact with the side of the detachable measuring panel 6 away from the limiting member 7.

The side of the lever 14 away from the measuring instrument body 1 is fixedly connected to multiple longitudinal anti-slip strips.
[0022] Working principle: When using this utility model, the user moves the lever 14, causing the lever 14 to drive the slider 10 to slide closer to the spring 13. This causes the spring 13 to be compressed and contract. When the slider 10 drags the surface of the detachable measuring panel 6, the detachable measuring panel 6 is pulled out, causing it to detach from the surface of the guide rail 5 for replacement. After the replacement of the detachable measuring panel 6 is completed, the lever 14 is released, allowing the spring 13 to extend. This causes the spring 13 to drag the slider 10 towards the detachable measuring panel 6, thus making the slider 10 fit against the detachable measuring panel 6 and limiting its position. This completes the disassembly and replacement of the detachable measuring panel 6, preventing the worn measuring surface from affecting the slope measurement results and ensuring the accuracy of the slope measurement.
[0023] In summary, this highway slope measuring instrument, by moving the lever 14, causes the slider 10 to slide towards the square spring 13, which compresses the spring 13, allowing the detachable measuring panel 6 to be pulled out for replacement. After replacement, releasing the lever 14 allows the spring 13 to extend, pushing the slider 10 to engage with the detachable measuring panel 6. This achieves the goal of replacing and fixing the measuring surface of the slope meter through a locking structure, preventing worn measuring surfaces from affecting the slope measurement results and ensuring the accuracy of the slope measurement.
