Simple type gradient measurer
This utility model belongs to slope measuring apparatus technical field, is specifically related to a kind of simple type gradient measurer.
The gradient is seen everywhere in our geographical environment, is widely present in such as highway subgrade, river levee, irrigation canals and ditches, stair
In building, gradient size could be constructed after will accurately measuring, and particularly occupies critical role on engineering construction.Existing
The slope measuring structure used people is relatively complicated, needs just to obtain the surveyed gradient through calculating during use, time-consuming
Arduously, and cost of manufacture is high.It is therefore desirable to propose to improve.
Utility model content
This utility model solves the technical problem that: providing a kind of simple type gradient measurer, this utility model is according to gravity
Principle design goes out the fork the most sagging with gravity, quickly draws gradient size, simple in construction, system by fork rotational angle
Facilitating, measure the gradient quick and precisely, cost of manufacture is low.
The technical solution adopted in the utility model: simple type gradient measurer, has domatic substrate, on described domatic substrate
Plane is provided with perpendicular support lath, and side, described support lath top is provided with angle index plate, described support lath top
End is provided with hanger bar, and described hanger bar one end is provided with the perpendicular fork being rotationally connected, and described fork middle and upper part is provided with one end
The instruction pin of orientation angle graduated tile.
Wherein, described domatic substrate upper surface is fixed with the L-type plate of two specular, said two L-type by screw
In the middle of plate, support lath lower end is clamped and fixed by screw.
Described hanger bar one end is provided with extension pin, and described fork top is provided with hanging hole, and described extension guide enters in hanging hole and realizes
It is rotationally connected.
Further, described fork lower end is provided with pendulum.
It is carved with angle value on the outside arc-shaped edges of described angle index plate.
Described domatic substrate uses plank to make.
This utility model advantage compared with prior art:
1, this programme goes out the fork the most sagging with gravity according to the downward principle design of gravity, by fork rotational angle
Quickly drawing gradient size, simple in construction, easy to make, cost of manufacture is low；
2, on the outside arc-shaped edges of angle index plate, it is carved with angle value, and is indicated by instruction pin, can quickly read slope
Degree size, measures numerical value quick and precisely；
3, domatic substrate uses plank to make, and can effectively alleviate total quality, easy to carry.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
1 embodiment of the present utility model is described below in conjunction with the accompanying drawings.
Simple type gradient measurer, has domatic substrate 1, and described domatic substrate 1 uses plank to make, can effectively alleviate whole
Weight, easy to carry.On described domatic substrate 1, plane is provided with perpendicular support lath 2, concrete, described domatic base
Plate 1 upper surface is fixed with in the middle of the L-type plate 11 of two specular, said two L-type plate 11 by screw 10 will support lath 2
Lower end is clamped and is fixed by screw.Side, described support lath 2 top is provided with angle index plate 4, outside described angle index plate 4
Angle value 12 it is carved with on portion's arc-shaped edges.Described support lath 2 top is provided with hanger bar 3, and described hanger bar 3 one end is provided with hangs down with it
The fork 5 being directly rotationally connected, concrete, described hanger bar 3 one end is provided with extension pin 6, and described fork 5 top is provided with hanging hole 7, described
Hang in pin 6 is inserted in hanging hole 7 and be rotationally connected, being rotationally connected beneficially fork 5 the most sagging with free gravity.Described fork
5 middle and upper parts are provided with the instruction pin 8 of one end orientation angle graduated tile 4, and instruction pin 8 can quickly read the gradient along with fork 5 rotates
Size, measures numerical value quick and precisely.Described fork 5 lower end is provided with pendulum 9, increases gravity sag sensitivity, be measure more accurate
This utility model goes out the fork 5 the most sagging with gravity according to the downward principle design of gravity, is rotated by fork 5
Angle quickly draws gradient size, simple in construction, and easy to make, cost of manufacture is low.
Above-described embodiment, preferred embodiment the most of the present utility model, not it is used for limiting this utility model practical range,
Therefore all with content described in this utility model claim done equivalence change, this utility model claim model all should be included in
