Abstract
The utility model discloses a band tape with a clutch cranking bar, composing a band tape buck, a band tape belt, a band tape band wheel, an adapting flange, a rocker arm, and a handle. The axis of the tape band wheel is in a rotary connection in the band tape buck. One end of the axis of the tape band wheel which passes through one side of the band tape buck is in hinged connection with one end of the rocker arm by the adapting flange; the other end of the rocker arm is connected with a handle. One end of the band tape belt is in curled connection around the surface of the tape band wheel. A position limiting hole which is corresponding to the handle is arranged on the band tape buck. The adapting flange is in rotary connection with the axis of the tape band wheel; a clutch structure is arranged between the adapting flange and the axis of the tape band wheel. The adapting flange and a rotary disk of the utility model are in rotary connection with each other. When the band tape belt is pulled out, the rocker arm is turned out, making the handle of the rocker arm arranged in the position limiting hole, and the rocker arm is not rotated together with the band tape belt. When the tape band is retracted, the rocker arm is overturned by 180 degrees, making the clutch camshaft inserted into a clutch concave pit arranged on the rotary disk, and the rocker arm is rotated together with the tape band wheel; thus, the clutch between the rocker arm and the tape band wheel is achieved. The problem of the possible injury to people due to the rotation of the rocker arm and the band tape belt can be effectively solved.
Description
Technical field
The utility model relates to a kind of engineering tape measure, specifically is a kind of tape measure that has the clutch crank, is mainly used in the range observation in fire-fighting, military affairs, building, the bridge construction.
Background technology
The chi tape spool and the rocking arm of existing tape measure directly link together, and crank is along with the chi tape spool rotates together when putting chi, and not only chi speed is put in influence, also may hurt sb.'s feelings; May reset in the rotation process of crank stops operating the chi belt wheel, has to crank is started just and can rework; If oppositely draw the chi band also the slide calliper rule zoning can occur, damage the chi band, and influence job schedule.
Summary of the invention
The purpose of this utility model just provides a kind of tape measure that has the clutch crank, with solve that existing tape measure exists owing to crank rotates the problem that may hurt sb.'s feelings and influence job schedule that causes with the chi band.
The technical solution of the utility model is: comprise chi frame, chi band, chi belt wheel, terminal pad, rocking arm and handle, the axle of chi belt wheel is rotatably connected in the chi frame, the chi frame that one end of chi belt shaft passes a side is hinged by terminal pad and rocking arm one end, and the other end of this rocking arm connects handle; Chi band one end connects and twists in the side face of chi belt wheel.The axle of described terminal pad and chi belt wheel is rotationally connected, and is provided with clutch between the two at them, is provided with the spacing hole corresponding with described handle on described chi frame.
Described clutch comprises rotating disk, the protruding axle of clutch, clutch pit and described terminal pad, rotating disk and coaxial the fixedlying connected of described chi belt wheel; Terminal pad is connected with described chi belt wheel coaxial rotation, be provided with the radial groove that coincide with described rocking arm width in the outer end of this terminal pad, described rocking arm one end is hinged at an end of this groove, be provided with through hole in bottom, be provided with the clutch pit corresponding with described lead to the hole site at the adjacent end of described rotating disk and terminal pad near this groove other end; Side at described rocking arm is provided with the protruding axle of the clutch corresponding with described clutch pit.
Described clutch pit is provided with 2～4 along circumference.
For being rotationally connected, when putting chi (pulling out the chi band), rocking arm is routed up in the spacing hole that makes its handle place the chi frame between terminal pad of the present utility model and the rotating disk, rocking arm does not rotate with the chi band; And when regaining the chi band, rocking arm is turned over turnback, and make in the clutch pit on the protruding axle of the clutch insertion rotating disk, make rocking arm and chi belt wheel with changeing, realized the clutch of rocking arm and chi belt wheel.
Because can clutch between rocking arm and the chi belt wheel,, that is: efficiently solve hurting sb.'s feelings of to cause owing to crank rotates with the chi band and influence the problem of job schedule so produced the beneficial effects of the utility model.

Fig. 1 is a general structure synoptic diagram of the present utility model;
Fig. 2 is the A-A cut-open view of Fig. 1.
Embodiment
Referring to Fig. 1 and Fig. 2, the utility model comprises chi frame 14, chi band 6, chi belt wheel 11, terminal pad 4, rotating disk 15, rocking arm 3 and handle 9, the axle of chi belt wheel 11 is rotatably connected in the chi frame 14, the chi frame 14 that the end that the chi belt wheel is 11 passes a side is fixedlyed connected with rotating disk 15, and terminal pad 4 is connected with rotating disk 15 coaxial rotation.Chi band 6 one ends connect and twist in the side face of chi belt wheel 11.Be provided with and the identical radial groove 7 of the width of described rocking arm 3 in the outer end of terminal pad 4, described rocking arm 3 one ends are hinged at an end of this groove 7, and the other end of rocking arm 3 connects handle 9.Be provided with through hole 5 near the bottom of groove 7 other ends, be provided with the clutch pit 10 corresponding with the position of described through hole 5 at described rotating disk 15 and terminal pad 4 adjacent ends.Be provided with the clutch protruding axle 8 corresponding in a side of described rocking arm 3 with described through hole 5 and clutch pit 10.On described chi frame 14, be provided with the spacing hole corresponding 2 with the position of described handle 9.The through hole 5 common clutches that constitute between terminal pad 4 and the chi belt wheel 11 on the protruding axle 8 of above-mentioned rotating disk 15, clutch, clutch pit 10 and the terminal pad 4.
Described clutch pit 10 can evenly be provided with 2～4 along circumference.End at the chi frame is provided with handle 1, is provided with draw ring 13 in the outer end of chi band 6, all is conventional structure, uses with convenient.
Being rotationally connected between terminal pad 4 and the chi belt wheel 11 adopts the axle 41 of terminal pad 4 to rotate the structure of the axle center hole that passes chi belt wheel 11.
Principle of work of the present utility model is: since between terminal pad 4 and the rotating disk 15 for being rotationally connected, so when pulling out chi band 6, rocking arm 3 is routed up in the spacing hole 2 that makes its handle place the chi frame, rocking arm 3 is with 11 rotations of chi belt wheel; And when regaining chi band 6, rocking arm 3 is turned over turnback, make the protruding axle 8 of clutch by in the clutch pit 10 on the 5 insertion rotating disks 15 of the through hole on the terminal pad 4, terminal pad 4 locks mutually with rotating disk 15 like this, and rocking arm 3 and chi belt wheel 11 are changeed together, has realized the clutch of rocking arm 3 with chi belt wheel 11.
