specific Embodiment approach 1

[0007] Specific implementation mode one: combine figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 Describe this embodiment, the non-contact height measuring ruler in this embodiment includes a horizontal ruler frame 1, a vertical ruler frame 2, an arc scale 3, a pointer 4, an adjusting bolt 5 and an adjusting nut 6, and the arc scale The scale face of ruler 3 is a quarter arc surface protruding outward along the radial direction, and the side of arc scale 3 is processed with scale, and described horizontal chi frame 1, vertical chi frame 2 and arc scale 3 The head and the tail are fixedly connected in turn to form a fan-shaped ruler frame. A through hole 7 is processed at the intersection of the vertical ruler frame 2 and the horizontal ruler frame 1. The adjustment bolt 5 passes through the through hole 7 and is connected with an adjustment nut 6. The pointer 4 is located in the fan-shaped ruler frame. In the plane where it is located, one end of the pointer 4 pa...

specific Embodiment approach 2

[0008] Specific implementation mode two: combination figure 1 , figure 2 and Figure 5 Note that the adjusting nut 6 in this embodiment is an ingot nut. The ingot nut controls the rotation of the adjusting bolt 5. By adjusting the ingot nut, the pointer 4 fixed on the adjusting bolt 5 swings with the rotation of the ingot nut, so that the pointer rotates to a position in line with the measuring point. The ingot nut makes the present invention Easy to operate and flexible. Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0009] Specific implementation mode three: combination figure 1 , figure 2 and Figure 5 Explain that the height of the vertical ruler frame 2 in this embodiment is 20 centimeters to 30 centimeters, the height of the observation window 11 is 15 centimeters to 25 centimeters, and the height of the observation window 11 is less than the height of the vertical ruler frame 2 . Because the observation window 11 is processed in the vertical ruler frame 2, the observation window 11 and the vertical ruler frame 2 provided in this way are conducive to the good observation of the surveyor, and the measurement result is accurate and the error is small. When the height of the vertical ruler frame 2 is 25 cm, when the height of observation window 11 is 20 centimeters, the observation window 11 on the vertical ruler frame 2 has the best effect of observing the measuring object at this time, and it is also convenient to observe the scale on the curved scale 3 indicated by the pointer 4 V...

Abstract

A non-contact height measuring ruler relates to a measuring ruler. The purpose of the present invention is to solve the problems of high price, low versatility and complicated calculation steps of the existing non-contact height measuring instruments due to the dangerous location of the measuring objects in the existing height measurement work. The ruler surface of the arc-shaped scale is a circular arc surface, the horizontal ruler frame, the vertical ruler frame and the arc-shaped ruler are sequentially fixed end to end to form a fan-shaped ruler frame, the adjusting bolt passes through the through hole to connect the adjusting nut, and the pointer is located in the In the plane where the fan-shaped ruler frame is located, one end of the pointer passes through the intersection of the vertical ruler frame and the horizontal ruler frame and is fixed on the adjustment bolt. There are two pointer protrusions on the end of the pointer near the adjustment bolt, and two pointer protrusions. A pointer gap is formed between them. The end of the pointer away from the adjusting bolt has a pointer sight, and the pointer sight is attached to the side of the arc scale scale, and there is an observation window on the vertical ruler frame. The present invention is used to measure height.

Description

technical field [0001] The invention relates to a measuring ruler, in particular to a non-contact height measuring ruler. Background technique [0002] At present, in the existing height measurement work, there is a problem that the survey workers cannot directly measure the height due to the steep terrain where the measurement object is located, and there will be a great potential safety hazard in the direct forced measurement. Although the theodolite used in the existing measurement work can be carried out Non-contact height measurement, but due to the high price of theodolite, poor versatility, the steps of measuring height and subsequent calculations are relatively cumbersome, which also makes the measurement work difficult. Contents of the invention [0003] The purpose of the present invention is to provide a non-contact height measuring ruler, to solve the existing safety hazards in the measurement work due to the steep terrain where the measurement object is locate...
