Abstract
The utility model provides a roller type length measuring device. According to the technical scheme of the utility model, the device comprises a roller and a shell fixedly provided with the roller. The device is characterized in that the roller is fixed to the front end of the shell and is provided with an angle sensor. The angle sensor is connected with a singlechip and the singlechip is connected with a display. The display is fixed to the top of the shell. The two sides of the shell are provided with a plurality of circular grooves. The rear end of the shell is provided with a power supply. The power supply is connected with the singlechip. Due to the adoption of the above technical scheme of the utility model, the device has the advantages of simple operation and high measuring precision. Meanwhile, the measuring operation can be realized only by a single person without the need of multi-person assistance. Therefore, both manpower and material resources are saved.
Description
Technical field
The utility model relates to a kind of instrument of measuring length, especially a kind of roller type length-measuring appliance.
Background technology
In the prior art, known technology is that people are when measuring object length, typically use the instrument measurements such as meter ruler, when the length of object was long, meter ruler length was inadequate like this, just needed repeatedly to measure, need many people to assist, complex operation not only, and affect measuring accuracy, this is the existing weak point of prior art.
Summary of the invention
The purpose of this utility model is exactly for the existing deficiency of prior art, and provides a kind of technical scheme of roller type length-measuring appliance, the measurement mechanism of this scheme, simple to operate, measuring accuracy is high, does not need many people to assist, one people can complete, and has saved manpower and materials.
This programme is achieved by the following technical measures: a kind of roller type length-measuring appliance, include roller, the housing of fixed idler whell, the characteristics of this programme are: described roller is fixed on the front end of housing, be provided with angular transducer on roller, described angular transducer is connected with a single-chip microcomputer, described single-chip microcomputer is connected with a display, described display is fixed on the top of housing, be provided with the groove of a plurality of circles in the both sides of housing, rear end at housing is provided with power supply, and described power supply is connected with single-chip microcomputer.Described single-chip microcomputer is AT89C52.Described display is liquid crystal display.Power supply is direct supply.
The beneficial effect of this programme can be learnt according to the narration to such scheme, owing in this scheme, roller being arranged, be provided with angular transducer on roller, the number of turns that the roller that can survey timely rolls, angular transducer passes the signal along to single-chip microcomputer, and single-chip microcomputer just can obtain the distance that housing moves according to the number of turns that roller rotates, show by display, fluted on housing, the staff can hold housing, avoids landing.This shows, the present invention compared with prior art has outstanding substantive distinguishing features and significant progressive, and the beneficial effect of its enforcement is also apparent.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment.
In figure, 1 is roller, and 2 is housing, and 3 is angular transducer, and 4 is display, and 5 is power supply, and 6 is groove.
