Abstract
The utility model discloses a compass capable of displaying the degree of an angle. The compass comprises a compass body, including a rotating shaft, a first support leg and a second support leg. The compass also comprises an angle sensing unit, a computing circuit and an angle degree displaying unit. Fixed on the first support leg, the angle sensing unit comprises a sliding sensing end, which is linked with the second support leg via a transmission component. The angle sensing unit and the angle degree displaying unit are connected with the computing circuit. The compass of the utility model has the beneficial effects that the compass has the function of displaying the degree of an angle, so that the drawing operation requires one less tool.
Description
Technical field
The utility model relates to a kind of compasses, especially a kind of compasses of ability angles of display.
Background technology
Known compasses do not possess the function of angles of display, not only want the compasses ruler during daily mapping, also need carry protractor, very inconvenience.
Summary of the invention
To existing compasses can not angles of display problem, the utility model provides a kind of compasses that can angles of display.
The technical scheme that the utility model technical solution problem is adopted is:
A kind of compasses of ability angles of display comprise compasses, and said compasses comprise rotating shaft, first supporting leg and second supporting leg; Wherein, Also comprise an angle induction device, counting circuit and an angle display unit, said angle induction device comprises the slip induction end; Said angle induction device is fixed on said first supporting leg; Said slip induction end is through drive disk assembly and the interlock of said second supporting leg, and said angle induction device is connected with said counting circuit, and said angle display unit is connected with said counting circuit.
The compasses of above-mentioned ability angles of display, wherein, said angle induction device is a potentiometer.
The compasses of above-mentioned ability angles of display, wherein, said angle induction device is an encoder.
The compasses of above-mentioned ability angles of display, wherein, said angle display unit is a LCDs.
The compasses of above-mentioned ability angles of display, wherein, said LCDs is the segmentation LCDs.
The compasses of above-mentioned ability angles of display, wherein, said LCDs is the lattice liquid crystal display screen.
The beneficial effect of the utility model is: make compasses possessed angles of display function, can carry an instrument less during mapping.
Description of drawings
Fig. 1 is the structure diagram of the compasses of the utility model ability angles of display;
Fig. 2 is that the circuit of the compasses of the utility model ability angles of display connects block diagram.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further, but not as the qualification of the utility model.
Compasses like Fig. 1, the utility model shown in Figure 2 ability angles of display comprise compasses 1; Compasses 1 comprise rotating shaft 11, first supporting leg 12 and second supporting leg 13, wherein, also comprise an angle induction device 2; Counting circuit and an angle display unit 3; Angle induction device 2 comprises the slip induction end, and angle induction device 2 is fixed on first supporting leg 12, and the slip induction end links through the drive disk assembly and second supporting leg 13; Angle induction device 2 is connected with counting circuit, and angle display unit 3 is connected with counting circuit.The operation principle of the compasses of the utility model ability angles of display is that when first supporting leg 12 and second supporting leg were opened in 13 minutes, the slip induction end that is fixed on the angle induction device 2 on first supporting leg 12 was because through drive disk assembly and 13 interlocks of second supporting leg; So can sense the angle of 13 of first supporting leg 12 and second supporting legs changes; And the angle sensed changed be sent to counting circuit, counting circuit calculates the concrete angle value of variation according to the calculation procedure of prevision; Show through angle display unit 3 then; Can also preset other calculation procedure in the counting circuit, do the calculating of others, also can be counting circuit established procedure online updating interface; The person of being to use can change the calculation procedure that presets in the counting circuit voluntarily, to realize more computing functions.
The compasses of above-mentioned ability angles of display; Wherein, Angle induction device 2 can be potentiometer or encoder; Potentiometer is applied in the required precision that common occasion is enough to satisfy the compasses that the utility model can angles of display, can use encoder as angle induction device in the occasion that precision is had requirements at the higher level.
The compasses of above-mentioned ability angles of display; Wherein, Angle display unit 3 is a LCDs, and LCDs is segmentation LCDs or lattice liquid crystal display screen, and segmentation LCDs cost is low; Can satisfy general application, the dot matrix liquid crystal display then has better result of use when needs show complex figure or User Defined figure.
The above is merely the utility model preferred embodiment; Be not thus the restriction the utility model claim; So the equivalent structure that all utilization the utility model specifications and diagramatic content have been done changes, and all is included in the protection domain of the utility model.
