Abstract
The utility model discloses a digital display angle level ruler which comprises a main ruler, wherein one end of the main ruler is connected with a driven ruler through a fastening piece, the driven ruler can rotate around the main ruler, and a horizontal bubble window and a vertical bubble window which contain bubbles are respectively fixed on the main ruler; an angle display unit is arranged on the main rule and connected with a storage battery arranged at the tail end of the main ruler; and the angle display unit comprises an angle display screen, an indicating lamp, a memory key and a power switch. The digital display angle level ruler can directly read the angle value through the angle display screen and has the advantages of simple structure, accurate measurement, convenient and rapid operation, and the like.
Description
Technical field
The utility model relates to a kind of surveying instrument, relates in particular to a kind ofly both can be used for horizontal survey, vertical survey, can be used for the level angle surveyor's staff of arbitrarily angled measurement again.
Background technology
Existing surveyor's staff practicality is strong inadequately, and applicability is wide inadequately, and measuring error is big, and measuring process is loaded down with trivial details, and angle value is difficult for calculating.
The utility model content
In order to overcome defective of the prior art, the utility model provides a kind of new digital angles of display surveyor's staff that both can directly pass through angle display screen reading angular value.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of digital angles of display surveyor's staff, comprise main scale, one end of described main scale by securing member be connected with can around the driven chi of rotation, the horizontal bubble form and the vertical water dwell windows of bubble are arranged in being fixed with respectively on described main scale; On the described main scale angular display unit is set, this display is connected with the accumulator of being located at the main scale end.
Described angular display unit is made up of angle display screen, pilot lamp, memory button and power switch.
The beneficial effects of the utility model are, can directly pass through angle display screen reading angular value, can be used for horizontal survey, vertical survey.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
A kind of digital angles of display surveyor's staff comprises main scale 1, an end of described main scale 1 by securing member 3 be connected with can around the driven chi 2 of rotation, securing member 3 can be regulated the degree of tightness between main scale 1 and the driven chi 2.Horizontal bubble form 4 and vertical water dwell windows 5 that bubble is arranged in being fixed with respectively on described main scale 1; On the described main scale 1 angular display unit 11 is set, this display 11 is connected with the accumulator 10 of being located at main scale 1 end.
Described angular display unit 11 is made up of angle display screen 6, pilot lamp 7, memory button 9 and power switch 8; Display screen 6 is used to show the numerical value of the angle between driven chi 2 and the main scale 1, and memory button 9 is used to save data, is convenient to inquiry; Power switch 8 is used for starting or closing display 11.
Described display 11 is identical with the traditional circuit connected mode with circuit between the accumulator 10, referring to prior art.
Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here can't give exhaustive to all embodiments.Everyly belong to the row that conspicuous variation that the technical solution of the utility model extends out or change still are in protection domain of the present utility model.
