Abstract
The utility model discloses a band tape comprising a band tape casing, a band tape belt, a rotating disk, a rotating disk shaft and a lock knob. The band tape casing presents a ball shape, the band tape belt is coiled in the middle of the rotating disk, and a mainspring chamber in which the mainspring is coiled is arranged on the right side of the rotating disk. The utility model has the characteristics of small volume, shapely appearance and convenient carryover. The utility model can be used as the tool for length measurement and can also be used as handicraft to appreciate.
Description
Technical field
The utility model relates to a kind of length metering apparatus, specifically a kind of tape measure.
Background technology
The handicraft tape measure that bijou chi band can be locked is subjected to liking of numerous users.But in the market, such tape measure mostly is pancake, and it is spherical also not having a kind of.This is because the turntable structure of existing this tape measure is fit to make pancake tape measure.The rotating disk of existing tape measure, its chi band and force return spring all are installed in the same plane of rotating disk, that is to say, inner ring at rotating disk reinstalls the power clockwork spring, at the outer ring of rotating disk coiling chi band, chi band and the force return spring this mounting means on rotating disk must be with larger-diameter chi shell, so the chi shell generally adopts pancake.If this structure of rotating disk will be made the handicraft tape measure of globulate, its volume is just bigger, and this not only takes inconvenience, and, increase production cost.
Summary of the invention
The technical problems to be solved in the utility model is at above-mentioned deficiency, designs a kind of bijou spherical tape measure.
Embodiment of the present utility model is: it comprises chi shell, chi band, rotating disk, turntable shaft, cage knob, and the chi shell is spherical in shape, and the rotating disk telophragma is around the chi band, and there is the clockwork spring chamber on the rotating disk right side, coiling clockwork spring in the clockwork spring chamber.
The utlity model has little, attractive in appearance, the portable advantage of volume, both can be used as the apparatus of long amount length, can be used as handicraft again and appreciate.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is unkitted the structural representation of chi band and clockwork spring for the utility model.
Fig. 3 is a contour structures synoptic diagram of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in the figure, the utility model comprises chi shell 2, chi band 6, rotating disk 1, turntable shaft 3, cage knob 9.Chi shell 2 is spherical in shape, and it is put together by two hemispherical Shells.Have a chi to take mouthful 13 and cage knob holes out of on chi shell 2, chi band 6 is taken mouth 13 out of from chi and is stretched out.In the inboard of chi shell 2 turntable shaft 3 is arranged, be with rotating disk 1 on the turntable shaft 3.Rotating disk 1 telophragma is around chi band 6, and there is clockwork spring chamber 11 on rotating disk 1 right side, coiling clockwork spring 4 in the clockwork spring chamber 11.4 one on clockwork spring is fixed on the turntable shaft 3, and the other end is fixed on the limit, chamber 5 in clockwork spring chamber.There is catch 8 in rotating disk 1 left side.
Cage knob 9 inner avris have two washers 7, and inner center has trepanning 12, and spring 10 is housed in the trepanning 12, and cage knob 9 is placed in the axle head of turntable shaft 3 by trepanning 12.Cage knob 9 outer ends are stuck in the cage knob hole.Hanging wire hole 14 is arranged on chi shell 2.
Principle of work of the present utility model is: pin cage knob 9 with hand, catch 7 and catch 8 stagger up and down, can outwards pull out chi band 6, the openhanded button 9 of unblanking, catch 7 and catch 8 are positioned at same plane, and catch 7 is blocked by catch 8, rotating disk 1 can not be rotated, and at this moment, chi band 6 pins in the position of being pulled out.As regaining chi band 6, pin cage knob with hand, catch 7 and catch 8 stagger up and down again, because the effect of 4 times power of clockwork spring drives dial rotation, chi band 6 is withdrawn in the chi shell 2 automatically.
Claims (7)
