[0001] The utility model relates to the technical field of slope measuring instruments, in particular to a multifunctional slope measuring instrument. Background Art

[0002] The slope measuring instrument is used to measure the slope during road construction. The slope measuring instrument consists of a handheld panel, a rotating ring, an arrow, a level rod, a bubble, a scale, and an adjusting knob. When in use, the worker holds the handheld panel and places the bottom against the slope of the road to be measured. Due to the slope, the bubble in the level rod shifts from the center position. The worker controls the rotation of the rotating ring by adjusting the knob, and then rotates the level rod until the bubble moves back to the center of the level rod. Finally, the worker measures the slope according to the scale indicated by the arrow.

[0003] The inventor found in his daily work that when the slope measuring instrument is in use, the handheld panel is against the road and the road is sloped, which causes the bubble in the level rod to shift from the center position.

By setting the adjustment component 2, when it is necessary to adjust the level rod 8 and the bubble 9, the driving mechanism 24 is used to rotate the gear 22, rotate the rotating ring 5, rotate the level rod 8, and move the bubble 9. At the same time, after the detection mechanism 23 detects that the bubble 9 has moved to the center position of the level rod 8, the rotation of the level rod 8 is stopped, thereby achieving the effect of conveniently adjusting the bubble 9 to the center position of the level rod 8 as much as possible. 23 includes a photoelectric sensor transmitter 231 and a photoelectric sensor receiver 232 installed on the inner arc surface of the rotating ring 5. The photoelectric sensor receiver 232 is used to receive the light source emitted by the photoelectric sensor transmitter 231 and penetrates the bubble 9. The photoelectric sensor transmitter 231 emits the light source. Since the light source cannot penetrate the black liquid, after the bubble 9 moves to the center position of the level ruler 8, the light source penetrates the bubble 9 and is received by the photoelectric sensor receiver 232. The driving mechanism 24 includes a motor 241 installed on the back of the handheld panel 1. The output end of the motor 241 is fixed to the gear 22.

The motor 241 uses a stepping motor to rotate the gear 22 in the installation cavity 21.

[0031] Reference Figure 4As shown, in this embodiment: the fixing component 3 includes a mounting groove 31 provided on both sides of the inner arc surface of the rotating ring 5, and the two ends of the level rod 8 are fixedly connected with the mounting blocks 32. The inner wall of the mounting groove 31 is provided with a fixing mechanism 33. When fixing the level rod 8, the level rod 8 is pushed so that the mounting block 32 slides in the mounting groove 31, and the mounting block 32 is fixed by the fixing mechanism 33, thereby fixing the level rod 8. The fixing mechanism 33 includes an extrusion block 331 slidably inserted at the bottom of the inner wall of the mounting groove 31. The cross section of the extrusion block 331 is trapezoidal.

[0032] Working principle:

[0033] When in use, the worker holds the handheld panel 1 and places the bottom against the measured road slope. Due to the slope, the bubble 9 in the level rod 8 is offset from the center position. The worker controls the rotating ring 5 to rotate by adjusting the knob, and then the level rod 8 rotates until the bubble 9 moves back to the center of the level rod 8. Finally, the worker measures the slope according to the scale 4 indicated by the arrow 10. When it is necessary to adjust the level rod 8 and the bubble 9, the motor 241 is started. The motor 241 uses a stepping motor to rotate the gear 22 in the installation cavity 21, which rotates the rotating ring 5, rotates the level rod 8, and moves the bubble 9. At the same time, the photoelectric sensor transmitter 231 emits a light source (the photoelectric sensor model is wweiguoE3Z-T61). Since the light source cannot penetrate the black liquid, the bubble 9 After moving to the center position of the level ruler 8, the light source penetrates the water bubble 9 and is received by the photoelectric sensor receiver 232, stopping the rotation of the motor 241 and the rotation of the level ruler 8, thereby achieving the purpose of conveniently adjusting the water bubble 9 to the center position of the level ruler 8. When fixing the level ruler 8, the level ruler 8 is pushed to make the mounting block 32 slide in the mounting groove 31, and the mounting block 32 squeezes the squeezing block 331 downward until the mounting block 32 moves to the side of the squeezing block 331. By setting the spring 332, the squeezing block 331 is reset to fix the mounting block 32, and then the level ruler 8 is fixed. By setting the rubber pad, the mounting block 32 is assisted to be fixed. By pulling out the tape measure 7 in the tape measure groove, the road length can be detected, thereby realizing multi-functions. By turning the handle 6, the tape measure 7 is retracted.
