Description

It is a kind of that with formula, one helps chi soon

Technical field

The utility model belongs to architectural engineering device field, more particularly to one kind is fast, and with formula, one helps chi.

Background technology

It is existing it is for building help chi need in use it is double use, a people help the people of chi one correct levelness, use It is extremely cumbersome, and help the chi to need to slide pointer manually in use, adjustment measurement distance requirement fitness is higher, and one As help chi in reading because helping the chi there is certain thickness, easily there is the inaccurate situation of reading, cause error larger, and The viewing angle requirement of chi is helped to look squarely, frequent many positions of measurement in a day in construction, or even to have many positions to be required for more Secondary measurement, this height for allowing for needing body to follow measured object during observed reading bends, the meeting of squatting of bending over for a long time Body burden is aggravated, and existing helps that chi is overweight long to be difficult to carry.

Utility model content

The purpose of this utility model is to provide a kind of need not bending the body to be capable of achieving the single with chi is helped of reading, in fact The characteristics of having showed Rapid reading, accurate reading, reduce the labour intensity of operating personnel.

The utility model is achieved through the following technical solutions：

There is provided one kind, with formula, one helps chi soon, and it includes chi shell, and main scale is fitted with chi shell, and the bottom of main scale is provided with water The flat boss for extending, is fitted with level meter, chi shell on boss and is provided with slide device in main scale side；Described slide device bag First gear, second gear, cingulum and pointer are included, described first gear and second gear are from top to bottom articulated in chi shell, Spacing between first gear and second gear is equal to the height of main scale, and cingulum is fitted with first gear and second gear, Pointer is fixed with cingulum, pointer bypasses main scale and extends in main scale front plate, is equipped with first gear or second gear There is rotary handle.

Further, also including transition gear, described transition gear is articulated on chi shell, and transition gear is located at the first tooth Between wheel and second gear.

Further, described main scale is made up of support bar body and measurement bar body, and described support bar body is rectangular strip body, Described measurement bar body is triangular strip body, and measurement bar body is fixed on support bar body side.

Further, described measurement bar body is right angled triangle bar body.

Further, stamp has graduation mark on main scale.

The utility model has the advantage that in terms of existing technologies：

Sliding drive mechanism is fitted with, the size that pointer is pointed to can be checked without bent angle, a people is in use It is operable, can check that the attitude of ruler is i.e. operable without manual intervention oneself by level meter, facilitate convenient.

Slipping mechanism drives vernier to slide up and down by gear teeth band drive system, and transition wheel guarantor is additionally provided with cingulum Card sliding precision, will not produce skidding or other interference.

The overall mechanism of the utility model coordinates reasonable, is easy to carry using pin-connected panel main scale, and main scale uses hollow setting, Lighter in weight, is highly convenient for using in work progress, can substantially reduce the work degree of operating personnel.

Specific embodiment

The utility model is described further below according to accompanying drawing：

As shown in Figure 1 and Figure 2, there is provided a kind of with formula, one helps chi soon, and it includes chi shell, and main scale is fitted with chi shell, main The bottom of chi is provided with horizontal-extending boss, is fitted with boss in level meter, chi shell and is provided with slide device in main scale side；Institute The slide device stated includes first gear, second gear, cingulum and pointer, and described first gear and second gear are respectively by upper It is articulated under in chi shell, the spacing between first gear and second gear is equal to the height of main scale, in first gear and second Transition gear is provided between gear, transition gear is articulated on chi shell, and cingulum, tooth are fitted with first gear and second gear Take and be fixed with pointer, pointer bypasses main scale and extends in main scale front plate, the indication end of pointer is located at main scale front, first Rotary handle is fitted with gear or second gear, the color of pointer is red.

Described main scale is made up of support bar body and measurement bar body, and described support bar body is rectangular strip body, described survey Amount bar body is triangular strip body, and measurement bar body is fixed on support bar body side,

The cross section of described measurement bar body is right angled triangle, and measurement bar body is right angled triangle bar body, on main scale Stamp has graduation mark.

Application method of the present utility model is described further below according to accompanying drawing.

The boss of main scale bottom is horizontally placed at by measured object in use, when level meter indicates to help chi level, Rotate rotary handle to drive first gear and second gear rotation and then drive cingulum, cingulum drives pointer to fluctuate, and works as finger When pin points to testee, operating personnel's record data or other observation personnel record pointers point to data.
