Abstract

The utility model discloses a simple sand table height ruler which is a measuring appliance for measuring the height of the vertical control point of a sand table in the manufacturing process of the sand table easily. The simple sand table height ruler comprises a movable horizontal ruler (1), a vertical ruler (2), a horizontal-ruler supporting plate (5) and a canting pull line (3); the horizontal-ruler supporting plate (5) is fixed and connected with the movable horizontal ruler (1), the vertical ruler (2) and the canting pull line (3), and the movable horizontal ruler (1) can move from left to right on the horizontal-ruler supporting plate (5); the vertical ruler (2) is vertical to the horizontal-ruler supporting plate (5), one end of the canting pull line (3) is fixed on the horizontal-ruler supporting plate (5), and the other end (B) is connected with a knob (4) by an elastic scaling device and can reciprocate on the vertical ruler (2). The simple sand table height ruler has the improvement and innovation that the simple sand table height ruler solves the problem of direct measuring and reading under the condition of arbitrary normal zero and arbitrary vertical dimension scale, the simple sand table height ruler overcomes the disadvantage of limitation for using, slow speed of the traditional method, and the traditional method is easy to make mistakes; the simple sand table height ruler has the characters of reasonable structure, firmness and higher popularizing and using values.

Description

Simple and easy sand table height gauge

Technical field: the utility model relates to a kind of simple and easy sand table height gauge, is a kind of apparatus of measuring that is used to measure sand table vertical control point height in the simple and easy sand table manufacturing process.

Background technology: simple and easy sand table is the relief block of making according to certain ratio of easy equipment such as silts.Owing to it is drawn materials simply, the convenient, fast decision maker of becoming of composting studies landform, the main foundation when being resolute.Especially its advantage is just more outstanding under field condition.Though be called " simple and easy " sand table, also require the landforms of composting similar to terrain, sand table vivid, true to nature can make the decision maker that sensation on the spot in person is arranged, in order to making correct decision.

Influencing simple and easy sand table factors of accuracy has a lot, and wherein how much elevation (starting at topocentric height by elevation datum) reference mark is the whether determinative of image of decision sand table, but the reference mark is many more, calculates, just measure trouble more.Determine that a vertical control point was divided into for four steps usually in the method for height on the sand table: the elevation of searching the reference mark on the first step figure; The second step reference mark elevation cuts starts at elevation; The 3rd step calculated the height of this reference mark on sand table according to given vertical scale; The 4th step was got the pairing height control lever in this reference mark with a centimetre dipstick metering.

One of method of using always in the prior art is that counter cooperates centimetre chi to use, and the shortcoming of this method mainly contains two: the one, and the reference mark is many more, and the time of sand table composting is long more; The 2nd, calculate to measure in the process and make mistakes easily, as do not subtract and start at face height etc.

Summary of the invention: the purpose of this utility model is at above-mentioned the deficiencies in the prior art, develops simple and easy sand table height gauge according to practical experience utilization mathematical principle.This chi can satisfy the requirement of starting at the simple and easy sand table of composting under face and the different vertical engineer's scale condition in difference.For achieving the above object, the utility model adopts following technical proposals: simple and easy sand table height gauge comprises crossfoot supporting plate (5), movable crossfoot (1), linear foot (2) and (3) four parts of lateral conductor.Crossfoot supporting plate (5) is mainly used in the activity crossfoot (1) that is connected and fixed, linear foot (2) and lateral conductor (3), and movable crossfoot (1) can be gone up move left and right at crossfoot supporting plate (5), is shaped on scale numerical value on it, and this numerical value is the elevation of lettering; Linear foot (2) is a centimetre chi, and is vertical with crossfoot supporting plate (5), and can go up move left and right at crossfoot supporting plate (5), and the numerical value of its position on movable crossfoot is the elevation of peak on the figure; Lateral conductor (3) one ends (A) are fixed on the crossfoot supporting plate (5), this numerical value shown on movable crossfoot is the face of starting at of sand table, the other end (B) links to each other with turn-knob (4) by elasticity device for zooming (6) and can move up and down in linear foot (2), and the numerical value of its position on linear foot is the height of the peak of sand table.

Progress of the present utility model and innovative point be to solve the face of starting at arbitrarily, any direct problem read of amount under the vertical scale condition, overcome classic method use limited to, speed slowly, the shortcoming of easily makeing mistakes.It is few and method is simple to measure the vertical control point step with this product, calculates, measures vertical control point and only needed for two steps: the first step, look into elevation on the figure; Second step, on chi, measure, both to have saved the time, mistakes such as counting loss can not appear again.This chi can be freely decomposes crossfoot and linear foot and combines convenient keeping.Characteristics with rational in infrastructure, sturdy and durable and higher popularizing value.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Embodiment:

With reference to Fig. 1, simple and easy sand table height gauge comprises crossfoot supporting plate 5, movable crossfoot 1,

linear foot

2 and 3 four parts of lateral conductor.Crossfoot supporting plate 5 is mainly used in the activity crossfoot 1 that is connected and fixed, linear foot 2 and lateral conductor 3.Movable crossfoot 1 can be on crossfoot supporting plate 5 move left and right, be shaped on scale numerical value on it, this numerical value is the elevation of lettering; Linear foot 2 is a centimetre chi, and is vertical with crossfoot supporting plate 5, and can be on crossfoot supporting plate 5 move left and right, the numerical value of its position on movable crossfoot is the elevation of peak on the figure; Lateral conductor 3 one end A are fixed on the crossfoot supporting plate 5, this numerical value shown on movable crossfoot is the face of starting at of sand table, other end B links to each other with turn-knob 4 by elasticity device for zooming 6 and can move up and down at linear foot 2, and the numerical value of its position on linear foot is the height of the peak of sand table.

Using method:

1, the face of the starting at elevation that requires according to operating condition, move left and right activity crossfoot 1 on crossfoot supporting plate 5 makes representative start at that numerical value overlaps with the A point on the movable crossfoot 1 of face;

2, find out apogee altitude in institute's heap scope on figure, get a round values that is higher than apogee altitude, mobile linear foot makes it the left side and overlaps with getting height value.Calculate height on this integer-valued sand table according to the vertical scale that provides, a centimetre footage value corresponding on B point (sand table peak height) and the linear foot 2 is coincided by adjustable knob 4, by elasticity device for zooming 6 that lateral conductor 3 is stretching then;

3, in this operating condition requires, highly just can on chi, directly measure on the sand table more arbitrarily.Concrete grammar is: the elevation control mark post is placed on corresponding elevation position on the crossfoot, and keeps mark post vertical with crossfoot in this position (parallel with linear foot), the distance between movable crossfoot and the lateral conductor is this height on sand table.
