Abstract
The utility model relates to an electronic rolling length measurer, which belongs to the measuring instrument field of measuring length, the problem which is should to be solved is that the length measurer provides a device which is provided with a display screen and can measure length in rolling mode, the proposal which is adopted by the measurer is that a rolling disc is fixed on the middle position of the lower portion of a shell with a shaft through a bearing, an electronic counting device is fixed on the middle position of the upper surface of the shell, wherein scales is homogeneously distributed on the outer end face of the rolling disc, and a pintle which contacts once with a sensing button when the rolling disc rolls a round is arranged on the inner end surface of the rolling disc. The electronic rolling length measurer is suitable for the loose measure of the length of straight lines and curved lines which are between various ground surface and buildings and the like.
Description
Technical field
The utility model electronic scroll length meter belongs to the measurement instrument field of measuring length.
Background technology
The present ruler measurement limited length of using in the life, if need to measure long slightly apart from the time, toward the contact measurement result that need superpose, and a people is difficult to finish, and also needs another people's assistance.Also have some remote measurement instruments, these instruments are all more valuable, and measurement expense is higher.
The utility model content
The utility model electronic scroll length meter problem to be solved is: but a kind of device that has the tolling measurement length of display screen is provided.
In order to solve the problems of the technologies described above, the scheme that the utility model electronic scroll length meter adopts is: the electronic scroll length meter, mainly comprise digital electronic unit and roller, rolling disk 1 is fixed on the lower middle position of housing 4 by bearing 2 and axle 3, is fixed with digital electronic unit 5 in the upper surface centre position of housing 4;
Described digital electronic unit 5 is made up of display screen 6, electronic chip 7, battery 8 and induction button 9, and battery 8 links to each other by lead with display screen 6 and electronic chip 7 respectively, electronic chip 7 respectively with display screen 6 with respond to button 9 and link to each other,
Evenly be provided with scale 10 on the outside end face of described rolling disk 1, the inner side end of rolling disk 1 be provided with when the 1 every rolling of rolling disk once week can with respond to button 9 and contact once pin 11;
Described housing 4 also is connected with handrail 12 and return idler 13;
Described housing 4 has transparent observing mouth 14 in the arranged outside of rolling disk 1 high scale 10.
The utility model electronic scroll length meter is compared with traditional technology has following beneficial effect: the design of rolling disk makes this device be particularly useful for the rough open-air rough measure of surface measurements, and a people gets final product easy manipulation, can conveniently read measurement result from display screen, this apparatus structure is simple, compact volume and convenience, easy operating.
Description of drawings
Fig. 1 is the structural representation of the utility model electronic scroll length meter;
Fig. 2 is the A-A cut-open view of the utility model electronic scroll length meter shown in Figure 1;
Fig. 3 is the hardware connection layout of the digital electronic unit 5 of the utility model electronic scroll length meter.
Embodiment
As Fig. 1-shown in Figure 2, the electronic scroll length meter mainly comprises digital electronic unit and roller, rolling disk 1 is fixed on the lower middle position of housing 4 by bearing 2 and axle 3, upper surface centre position at housing 4 is fixed with digital electronic unit 5, digital electronic unit 5 is by display screen 6, electronic chip 7, battery 8 and induction button 9 are formed, battery 8 links to each other by lead with display screen 6 and electronic chip 7 respectively, electronic chip 7 links to each other with induction button 9 with display screen 6 respectively, evenly be provided with scale 10 on the outside end face of rolling disk 1, scale can be as accurate as millimeter, the inner side end of rolling disk 1 be provided with when the 1 every rolling of rolling disk once week can with respond to button 9 and contact once pin 11; Housing 4 also is connected with handrail 12 and return idler 13.Housing 4 has transparent observing mouth 14 in the arranged outside of rolling disk 1 high scale 10, helps the user to read scale and reading.
Digital electronic unit 5 as shown in Figure 3, an end of battery 8 connects display screen 6, and the other end connects electronic chip 7, and display screen 6 is connected with electronic chip 7, and electronic chip 7 is connected with induction button 9.Display screen 6 is provided with start button, reset button, computed push-buttom; Electronic chip 7 is similar to existing counter, when induction button 9 is whenever pressed next time, it automatically increases a fixed value that equates with rolling disk 1 girth, and measurement afterwards displayed value adds the reading of peak correspondence on the scale 10 of rolling disk 1, and both add up and are measured actual distance.
When using the electronic scroll length meter, at first manually stirring the reading that rolling disk 1 makes its scale 10 is zero, it is " 0 " scale that transparent observing mouth 14 is seen the scale 10 on the rolling disk 1, pin 11 overlaps with induction button 9, and at peak as Fig. 1, then the digital electronic unit 5 of electronic scroll length meter is opened, press start button, again the lowermost end of rolling disk 1 is aimed at the article starting point of preparing measurement, can begin to measure, promote handrail, the electronic scroll length meter moves forward along with the rolling of rolling disk 1, pin 11 on the rolling disk 1 also rotates thereupon, whenever pin 11 turns to the induction button 9 of digital electronic unit 5, make original counting increase a fixed value automatically, whenever once contact, counting just adds one, up to the article terminal point that the electronic scroll length meter is rolled to measurement, the reading on the reading displayed screen 6 adds the number of division on the rolling disk 1, promptly is the length of measured article.
