Abstract

The utility model discloses a multipurpose automatic leather measuring tape, and relate to a measuring tape. The multipurpose automatic leather measuring tape comprises a rolling crank arranged on oneside of a measuring tape shell body and a measuring tape arranged in the measuring tape shell body and is characterized by further comprising an electric box arranged on the other corresponding sideof the measuring tape shell body; a miniature motor whose rotating shaft is taken as the rolling shaft of the measuring tape and a battery box electrically connected with the miniature motor are arranged in the electric box; a motor switch is arranged on the electric box; a positioning through hole is formed on a draw hook at the extending end of the measuring tape; the central shaft of the positioning through hole is corresponding to the zero-scale line of the measuring tape; a slide block which can slide on the measuring tape and be fixed in any position of the measuring tape is also arranged on the measuring tape; and a paintbrush through hole penetrating through the measuring tape is formed on the slide block. The utility model automatically takes back the extending measuring tape, isprovided with a straight measurement tool included in the ordinary leather measuring tape, and can draw a circle, in particular to a great circle.

Description

A kind of automatic leather measuring tape of using more

Technical field

The utility model relates to a kind of tape measure, relates in particular to a kind of automatic leather measuring tape of using more.

Background technology

Leather measuring tape is as the survey instrument that is in daily use on the engineering, the convenience of its use is very important for the engineering staff, yet the leather measuring tape that generally uses but exists two problems at present, it is convenient not to the utmost to use: 1. present its longest dimension of common leather measuring tape can reach 100m, each manual scrolling of scrolling crank that all must use tape measure housing one side that finishes of measuring is taken in tape measure return, and wastes time and energy.2. present common leather measuring tape function is too single, can only be as simple line measurement instrument, for the engineering staff, the instrument that carries at one's side is very many, numerous instruments be burden also be trouble, the work that a plurality of instruments can be integrated to each engineering staff all is Gospel.

The utility model content

At the problem that above-mentioned prior art exists, the utility model provides a kind of and has used automatic leather measuring tape more, can automatically the tape measure that stretches out be taken in, and not only have the line measurement instrument of common leather measuring tape can also draw circle, especially draws great circle.

The technical solution of the utility model is: a kind of automatic leather measuring tapes of using more, comprise the scrolling crank of being located at tape measure housing one side, be located at the tape measure in the tape measure housing, also comprise the electronic box of being located at the corresponding opposite side of tape measure housing, be provided with the double micromachine of making the leather measuring tape spool of its rotating shaft in the electronic box, and the battery case that is electrically connected with micromachine, electronic box is provided with motor switch; Offer a location through hole on the drag hook of tape measure external part, the zero graduation line of the corresponding tape measure of the central shaft of positioning through hole, also be provided with one on the tape measure and can on tape measure, slide and can be fixed on any slide block of tape measure, offer the paintbrush through hole that does not run through the tape measure face on the slide block.

As preferably, described slide block is the rectangular parallelepiped spare that offers through hole or chute, tape measure passes through hole or chute slides slide block thereon, also be provided with on the rectangular parallelepiped spare to connect the surface to through hole or chute cavity and be positioned at the screw of tape measure face top, and and the trip bolt of screw correspondence.

The beneficial effects of the utility model are: take in the tape measure that stretches out by automatic rotation of the micromachine of tape measure housing one side, and convenient and swift, can also manually take in by original scrolling crank when needing; After measuring length, its numerical value can be fixed by slide block, so that multi-facetedly measure same numerical value; Except measure length the same with common leather measuring tape also can be drawn circle, with the positioning through hole is the center of circle, nail that will be corresponding with the positioning through hole size or other fixers pass positioning through hole and determine circular, paintbrush is passed the paintbrush through hole, sliding slider sets radius, and slide block is fixed, and can draw circle easily, the maximum circle that can draw radius 100m, this is the great circle that existing compasses can't be drawn;
