Abstract
The invention discloses a measuring tape with a circle-drawing function. The measuring tape comprises a ruler box and a ruler band, wherein the side wall of the ruler box is provided with a collimation apparatus, a light transmitting hole matching the collimation apparatus is reserved in the ruler box, the ruler band is provided with a limiting apparatus, a scale hole and a positioning hole which match scales of the ruler band are reserved in a second upper plate body, the two ends of an upper plate body and the two ends of a lower plate body are movably connected through support plates, the central portion of the portion between the upper plate body and the lower plate body is provided with an elastic member, and a positioning needle is arranged at an outlet of the ruler band of the ruler box. According to the invention, whether the surface of a measured workpiece is perfectly straight is measured through the collimation apparatus, at the same time, the limiting apparatus is used for determining a radius of a circle, the positioning needle is used for determining a circle center, a user can draw a needed circle conveniently, and the functions of the measuring tape are enriched.
Description
Technical field
The present invention relates to survey tool technical field, specially a kind of tape measure for justifying function with picture.
Background technology
Tape measure is the measuring tool commonly used in producing and living.What everybody was frequently seen is steel tape, and building and finishing are conventional, is also one of family's indispensability instrument.But present tape measure work relatively simple can function only as the effect of line measurement, more meaningful function can not be played during the production in people is raw and living, therefore, a kind of it is proposed that tape measure for justifying function with picture.
The content of the invention
It is an object of the invention to provide a kind of tape measure for justifying function with picture, to solve the problems, such as to be proposed in above-mentioned background technology.
To achieve the above object, the present invention provides following technical scheme：A kind of tape measure for justifying function with picture, including chi box and tape, one end insertion chi box of the tape, the other end of the tape is installed with hook, collimator apparatus is provided with the side wall in the tape exit of the chi box, the collimator apparatus is by line of collimation generator, open the light is connected and composed with power supply device by electric conductor, and the loophole matched with collimator apparatus is left on the chi box；
Slideway is offered in the tape, and stopping means is installed on slideway, the stopping means includes upper plate body, lower body, supporting plate and elastic component, the upper plate body is hinged is constituted successively by the first upper plate body, the second upper plate body and the 3rd upper plate body, second upper plate body leaves the scale sky and location hole of matching tape scale, the both sides of the upper plate body and lower body are flexibly connected by supporting plate, and the middle part between the upper plate body and lower body is provided with elastic component, the tape exit of the chi box is provided with the pilot pin for determining the center of circle.
Preferably, the two ends inner side of the upper plate body and lower body is equipped with slipmat.
Preferably, the elastic component is helical spring or the air spring for being provided with through hole.
Compared with prior art, the beneficial effects of the invention are as follows：Whether the present invention is straight by the surface for measuring measured workpiece in terms of collimator apparatus, while stopping means is used to determine the radius of circle, pilot pin determines the center of circle, is that user easily draws out required circle, is the feature-rich of tape measure.
