Abstract
A kind of convex surface two o'clock distance measurement tools described in the utility model, including graduated scale, filament, graduated scale starting point end is fixedly connected by rivet with connection frame, connection frame is socketed on pillar bottom end, pillar bottom end is fixedly connected on pedestal, and the zero graduation line of graduated scale exposes to connection frame, and is bonded with fine needle on the zero graduation line of graduated scale, vertically downward, and there is filament in system to the pin hole of fine needle at pin hole；Pedestal be hollow hemisphere shape structure, inside be bonded with plasticine；This device is easy to operate, and can intuitively check very much measurement result, reduces measurement bring error indirectly.
Description
Technical field
The utility model relates to measuring tool, specifically a kind of convex surface two o'clock distance measurement tools.
Background technique
At present in daily life and teaching, individual filament measurement is commonly used in measurement for distance between two points on convex surface,
It first makes marks in convex surface starting point, while also on convex surface, terminal makes marks, then filament is taken and is read on graduated scale, the number of operation
It is more, it cannot intuitively go to check that measurement result, the error of measurement are big and time-consuming and laborious very much.
Utility model content
Against the above technical problems, the utility model technical effect to be achieved is to provide with easy to operate, more
The convex surface two o'clock distance measurement tools intuitively measured.
In order to solve the above technical problems, a kind of convex surface two o'clock distance measurement tools described in the utility model, including scale
Ruler, filament, graduated scale starting point end are fixedly connected by rivet with connection frame, and the connection frame is socketed on pillar bottom end, institute
It states pillar bottom end and is fixedly connected on pedestal, the zero graduation line of the graduated scale exposes to the connection frame, and the graduated scale
It is bonded with fine needle on zero graduation line, vertically downward, and there is the filament in system to the pin hole of the fine needle at the pin hole.
Further, the pedestal be hollow hemisphere shape structure, inside be bonded with plasticine.
Compared with the prior art, the utility model has the following advantages:
1, the measurement markers twice of conventional convex surface two o'clock range measurement have been changed to one-shot measurement label by the utility model, and
Point-to-point transmission measurement in convex surface has been changed to direct measurement from indirect measurement, the number of label and measurement has been reduced, reduces error.
2, the utility model can adjust at any time the plasticine deformation of pedestal, pedestal is adjusted to consolidate according to different convex surfaces
Due to the suitable position convenient for convex surface measurement, to complete the measurement of different convex surface distance between two points.
3, the utility model can reach rapid survey, convenient to use in daily life, teaching test and engineering survey
Effect.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the portion A enlarged drawing in Fig. 1.
In figure: 1, pedestal, 2, pillar, 3, connection frame, 4, graduated scale, 5, rivet, 6, fine needle, 6-1, pin hole, 7, filament, 8,
Plasticine.
Specific embodiment
Illustrate to be described further the utility model with reference to the accompanying drawing.
A kind of convex surface two o'clock distance measurement tools as shown in Figure 1, 2, including graduated scale 4, filament 7,4 starting point end of graduated scale
It is fixedly connected by rivet 5 with connection frame 3, connection frame 3 is socketed on 2 bottom end of pillar, and 2 bottom end of pillar is fixedly connected on pedestal 1, carves
The zero graduation line of degree ruler 4 exposes to connection frame 3, and fine needle 6 is bonded on the zero graduation line of graduated scale 4, the pin hole 6-1 of fine needle 6
Vertically downward, and at pin hole 6-1 there is filament 7 in system；Pedestal 1 be hollow hemisphere shape structure, inside be bonded with plasticine 8.
The working process of the utility model is as follows: before carrying out the range measurement of convex surface two o'clock, first check the institute of the measuring tool
There is device whether intact, plasticine 8 is bonded on the bottom surface of pedestal 1；The position for needing the two o'clock measured is determined on tested convex surface
It sets, the end alignment of pin hole 6-1 on this measuring tool is allowed to need to measure the starting point of distance, at the same time firmly pressing pedestal 1, benefit
Pedestal 1 is stably fixed on convex surface with the viscosity and plasticity of plasticine on 1 bottom surface of pedestal, then filament 7 is tensed, along
Convex surface is made marks in terminal point with pen by being measured the terminal of distance, then filament 7 is pulled to it is parallel with the scale of graduated scale 4,
The numerical value on the corresponding graduation mark of mark point, as the distance between convex surface Origin And Destination are looked for, convex surface point-to-point transmission is completed with this
The measurement of distance；This device is easy to operate, and can intuitively check very much measurement result, reduces measurement bring error indirectly.
