Abstract

The utility model provides a digital display tool based on multiple high-precision angle sensors, and belongs to the technical field of hand-held electronic tools. The digital display tool solves the problems of an existing digital display bevel protractor, for example, precise measurement of a small angle is difficult to realize. The digital display tool comprises a main ruler, a bevel protractor and the first angle sensor. One end of the main ruler is in rotatable connection with one end of the bevel protractor. The first angle sensor is arranged at the connecting part. The main ruler is provided with a digital display, a vertical water bubble and a horizontal water bubble. The other ends of the main ruler and the bevel protractor are provided with the second angle sensor corresponding to the first angle sensor. The second angle sensor comprises a brush sheet and a resistor which are respectively arranged on one side of the main ruler and one side of the bevel protractor, and the two sides face each other. The digital display tool is high in measuring precision, a user can visually understand the angle of a measured object, and the digital display tool is simple and practical.

Description

A kind of digital display instrument based on high precision, multi-angle sensor
Technical field
The utility model belongs to handheld electronic class technical field of tools, relates to a kind of digital display instrument based on high precision, multi-angle sensor.
Background technology
As everyone knows, bevel protractor is an important tool indispensable in daily life, is widely used in the every field such as building, traffic, production, teaching.Under the background of advancing by leaps and bounds in current electronic technology, the advantage such as the more traditional mechanical Angle-Measuring Equipment of Electromic Digit Display Angle Ruler has simple to operate, and angle is directly perceived, has good market outlook and using value.
The single angular transducer of the general employing of the angular transducer of China's Digit Display Angle Ruler at present, as Chinese patent " Electromic Digit Display Angle Ruler " (publication number: CN2876699) discloses a kind of Electromic Digit Display Angle Ruler, it comprises main scale, bevel protractor and angular transducer, angular transducer is located between main scale and bevel protractor, on main scale, be provided with air level and display, angular transducer comprises bearing, support plate, transmission shaft, signal emitting plate, signal dash receiver, sensor and connection basin.But being subject to the restriction of sensor and analogue signal acquisition circuit, the Digit Display Angle Ruler of single angular transducer, is difficult to realize low-angle accurate measurement.
Utility model content
The purpose of this utility model is for the existing the problems referred to above of existing Digit Display Angle Ruler, and has proposed a kind of Digit Display Angle Ruler of multi-angle sensor.
The purpose of this utility model can realize by following technical proposal: a kind of based on high precision, the digital display instrument of multi-angle sensor, comprise main scale, bevel protractor and the first angular transducer, one end of main scale and one end of bevel protractor are rotationally connected, the first angular transducer is arranged on junction, main scale is provided with digital indicator, vertical bubble and horizontal bubble, it is characterized in that, described main scale and bevel protractor are provided with the second angular transducer with respect to the other end that the first angular transducer is set, the second angular transducer comprises brushing piece and resistance, both divide and are located at main scale and a bevel protractor side in opposite directions.
In above-mentioned a kind of digital display instrument based on high precision, multi-angle sensor, described resistance is carbon film.
In the utility model, the first angle sensor structure is same as the prior art for the angular transducer of main scale and bevel protractor junction, the utility model is mainly improved is to be not only provided with angular transducer at main scale and bevel protractor junction, also be provided with angular transducer at other positions of main scale, in the time of small angle measurement, because angle is too little, the first angular transducer can not accurately be measured, and can realize low-angle accurately measure by the second angular transducer.
As to further improvement of the utility model, on described main scale and bevel protractor, between above-mentioned the first angular transducer and the second angular transducer, be also at least provided with the 3rd angular transducer, the 3rd angle sensor structure is identical with the second angular transducer.
Several the 3rd angular transducers also can be set as required, can be arranged on the optional position between main scale and bevel protractor.
When the utility model work, main scale and bevel protractor relatively rotate, in the time measuring low-angle, can utilize the rotational travel of main scale and bevel protractor far-end much larger than the characteristic of link, make the contact portion generation significant change between brushing piece and carbon resister, produce a resistance value, on digital indicator, demonstrate measured angle value after being converted to electronic signal.
Compared with prior art, the utility model can accurately take measurement of an angle, and its measurement range is 0 degree-360 degree, and measuring accuracy 0.1 is spent, and angle measurement error is little.In addition, can allow user recognize intuitively the angle of testee by digital indicator, simple and practical.
Accompanying drawing explanation
Fig. 1 is structural representation provided by the utility model.
In figure, 1, main scale, 2, bevel protractor, 3, the first angular transducer, 4, digital indicator, 5, vertical bubble, 6, horizontal bubble, 7, brushing piece, 8, resistance.
Embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in Figure 1, a kind of based on high precision, the digital display instrument of multi-angle sensor, it is provided with main scale 1, bevel protractor 2, the first angular transducer 3 and the second angle angular transducer, described main scale 1 and bevel protractor 2 can relatively rotate by connection rotating shaft, described main scale 1 is provided with digital indicator 4, vertical bubble 5 and horizontal bubble 6, the structure of described the first angular transducer 3 and same as the prior art with position relationship and the annexation of main scale 1 and bevel protractor 2, the second angular transducer comprises brushing piece 7 and resistance 8, described resistance 8 is carbon resister, brushing piece 7 and resistance 8 are located at respectively the distal end of main scale 1 and bevel protractor 2, resistance 8 is located at the inner side of main scale 1, it is corresponding with resistance 8 in opposite directions that brushing piece 7 is located at bevel protractor 2 inner sides.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
