Abstract
A flexible tape is prepared for setting a contact roller and counting unit of contact roller as well as counting display unit in tape box, fitting tap belt closely on contact roller, making surface of contact roller move in the same linear speed when tape belt is moved, using contact roller counting-unit to record movement of contact roller and presenting recorded movement to user by counting display unit.
Description
Technical field
The invention belongs to survey instrument, particularly relate to tape measure.
Background technology
Tape measure is a kind of survey instrument in the equal widespread use of various occasions, is mainly used in to measure all kinds of length parameters.With regard to tape measure, most important two convenience that index should be measuring accuracy and use.
Tape measure of the prior art generally includes chi box and chi band, and chi band subscript is shown with scale, is coiled into to be provided in the chi box, during use the chi band is pulled out, and measures length with the scale on the chi band.Usually, the material of chi band is irony or organic material, the stability of irony chi band better, though use and the use of multiple environment through long-time, also can not produce bigger deformation, but its shortcoming is that quality own is bigger, when needs are done very longly to the chi band, as more than 30 meters the time, irony chi band is too heavy; Organic chi band is then just in time opposite---lighter, but stable inadequately, use a period of time, particularly use a period of time in the bigger environment of the temperature difference or under the situation of fatigue of materials after, the chi band can produce deformation, causes measuring accuracy to descend.
Another problem is that no matter the chi band of which kind of material in order to indicate scale, must be made the band shape of Bao Erbian, promptly the xsect of chi band is that very big rectangle of length breadth ratio or minor face are the rectangle of fillet; And in actual use, the chi band that tends to pull out twists, and this has just further influenced measuring accuracy, also influences the serviceable life of tape measure.
Summary of the invention
The present invention wishes to solve is the problem that precision, life-span and the convenience of tape measure can not be held concurrently, and a kind of accurate, light tape measure is provided.
The present invention also wishes to solve the problem that the chi band is turned round volume simultaneously, provides a kind of steel wire that can adopt as the tape measure of measuring media.
The present invention addresses the above problem to have adopted following technical scheme: tape measure, comprise chi box and chi band, and the chi band places in the chi box in the coiling mode, it is characterized in that: also have a roller and roller counting assembly and counting display device in the chi box; The chi band is close on the roller, and when the chi band moved, the surface of roller was with identical linear velocity motion; The roller counting assembly writes down the motion conditions of roller, and presents to the user by counting display device.
Further, the present invention also can adopt following scheme:
Described roller counting assembly can be in the roller side some marks to be set, with the traverse of photoelectric sensor record roller; Described mark can be the sensitivity speck of different colours, also can be in the punching of roller side, in order to obtain different sensitization values;
When adopting photoelectric counting, described counting display device comprises a display screen and a chip, and chip is electrically connected with described photoelectric sensor, receives its signal and is converted to length parameter by default operation program, and present to the user by display screen.
Described roller counting assembly also can be gear set, one of them gear and roller coaxial rotation, and drive other gear movements;
Therewith correspondingly, described counting display device is a digit wheel, with described gear set engagement.
In order to make the chi band can be close on the roller, several alternative plans are arranged; First chi band is close on the roller by a stretching pulley; It two is that the chi band is an irony, and roller is the magnetic material, and the chi band is adsorbed on the roller; It three is the length of chi band and roller contact portion, greater than 1/3rd of roller girth.
The present invention also can adopt these technical schemes: the xsect of described chi band is for circular; Also be provided with motor and gear set in the chi box, drive the motion of chi band.
Measuring principle of the present invention is that the chi band is close on the roller, and the move distance of chi band equals the move distance of roller excircle; By measuring the movement angle of roller, just can accurately calculate the movement length of its excircle.Therefore, the precision of measuring accuracy of the present invention and chi band and stability are irrelevant, and only relevant with the precision and the stability of roller; Obviously, the accuracy class that roller can reach is higher, also easier manufacturing.In other words, the present invention does not have any requirement to material, the precision of chi band, and bigger advantage is arranged when making the tape measure of big specification.
On the other hand, owing to need not indicate scale on the chi band, the chi band just need not be done and become band, but can make any elongated shape.Such as, directly adopt steel wire, so not only saved wide variety of materials, also omitted the process of chi band, lighter when using simultaneously, can twist arbitrarily, the beneficial effect that is brought is many-sided.

Embodiment
Embodiment 1: tape measure comprises chi box and chi band 1 as shown in Figure 1, and chi band 1 is thinner steel wire, places in the rotating shaft 9 in the chi box in the coiling mode, also has a roller 2 and roller counting device in the chi box, and numeration display device 4; The roller counting device is made up of the photoelectric sensor 3 of the mark on the roller 6 and this mark of identification, by the traverse of this photoelectric sensor record roller; Chi band 1 is close on the roller 2, stretches out outside the chi box after walking around certain angle, and the contact portion length of itself and roller circumference is greater than 1/3rd of roller girth; When 1 motion of chi band, the circumferential surface of roller 2 is with identical linear velocity motion, and the roller counting device writes down the motion conditions of roller, and presents to the user by the numeration display device.Described roller counting device is provided with some through holes 6 in the roller side, with the traverse of photoelectric sensor 3 record rollers.Corresponding numeration display device 4 comprises a display screen and a chip, and chip is electrically connected with described photoelectric sensor, receives its signal and is converted to length parameter by default operation program, and present to the user by the display screen in the numeration display device 4.
Embodiment 2: tape measure comprises chi box and chi band 1 as shown in Figure 2, and chi band 1 places in the rotating shaft 9 in the chi box in the coiling mode, also has a roller 2 and stretching pulley 5 in the chi box, and this stretching pulley overlays chi band 1 on roller 2 near roller; Present embodiment also comprises the gear set of being made up of gear 71,72,73,74, its middle gear 71 and roller 2 coaxial rotation, and drive other gear movements, gear 74 is meshing with each other with digit wheel 8; When the chi band moved, the roller circumference was with the motion of identical linear velocity, roller by with the gear driven gear set of its coaxial rotation, and then drive digit wheel 8 video datas.
