Abstract
The utility model discloses an electronic display scale, which comprises a straight scale, a liquid crystal display screen, two indicating pointers and a resistance length measurer. One of the indicating pointers is fixed at one end of the straight scale while the other indicating pointer is movably arranged on the straight scale and capable of moving, the resistance length measurer and the indicating pointers form a circuit capable of converting resistance into length data, and the liquid crystal display screen, the indicating pointers and the resistance length measurer are arranged on the straight scale. The electronic display scale has the advantages that the distance between the two indicating pointers can be displayed accurately on the liquid crystal display screen after the indicating pointers are shifted to corresponding positions when in plotting or length measurement, and accordingly the electronic display scale is quite convenient and practical.
Description
Technical field
The utility model relates to a kind of schooling apparatus, specifically a kind of ruler.
Background technology
Ruler is the drawing schooling apparatus of using always, but common ruler often is difficult to very pin-point reading, and very wastes time and energy when measuring length or drawing the straight line of certain-length.
The utility model content
The purpose of this utility model is to provide a kind of electronics to show chi, and this electronics shows that chi can accurately show the length of being measured, and makes drawing and measures accurate more, convenient and quick.
The technical scheme in the invention for solving the technical problem is:
A kind of electronics shows chi, comprises ruler, also comprises display screen; Two pointers: one of them is fixed on an end of ruler, and another is actively installed on the ruler, and can move; Resistance device for measuring length:, the size of resistance is changed into length data with described pointer forming circuit loop; Foregoing liquid crystal display screen, pointer and resistance device for measuring length are arranged on the ruler.
Described display is a little LCDs, is used for showing to come the length data of self-resistance device for measuring length.
Described resistance device for measuring length comprises chip, slide resistor.One end of this slide resistor links to each other with one of them pointer, and the other end links to each other with another pointer.This chip can be converted into length data to the resistance sizes of measuring by pointer, and connects display screen by lead, shows on display screen.
Principle of the present utility model is a basis: the resistance of conductor is directly proportional with its length.When pointer slides, measure the measured object of different length, the length of swept resistance also changes thereupon.Chip then is converted into length data to resistance sizes by the default transforming relationship of reserving.
The beneficial effects of the utility model are: when drawing or measure length, mobile pointer can show length between two pointers, very convenient practicality accurately to corresponding position indicator.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1. resistance device for measuring length, 2. LCD, 3. pointer, 4. ruler.
Embodiment
As shown in Figure 1, a kind of electronics shows chi, comprises ruler 4, also comprises LCDs 2; Two pointers 3: one of them is fixed on an end of ruler, and another is actively installed on the ruler 4, and can move; Resistance device for measuring length 1:, the size of resistance is changed into length data with pointer 3 forming circuit loops; Foregoing liquid crystal display screen 2, pointer 3 and resistance device for measuring length 1 all are arranged on the ruler 4
Described resistance device for measuring length 1 comprises chip, slide resistor.One end of this slide resistor 1 links to each other with one of them pointer 3, and the other end links to each other with another pointer 3.This chip can be converted into length data to the resistance sizes of measuring 1 by pointer, and connects LCDs 2 by lead, shows on LCDs 2.
When drawing or measure length, mobile pointer 3 is to corresponding position, and LCD 2 can show the length between two pointers 3, very convenient practicality accurately.
