Description
Technical field
The utility model belongs to length measurer technical field, more particularly relates to the improvement of the steel tape that is used for length metering.
Background technology
Usually length is called tape more than or equal to 30 meters tape measure.Tape measures such as commercially available 30m, 50m, 100m all are tapes.The take-up of existing tape is carried out to shake the volume mode.Be that turning handle directly drives chi core rotation, thus with the chi tape wrapping on the chi core.The rocking handle of this mechanism and chi core rotate synchronously, and shortcoming is that take-up speed is slow, and is time-consuming.This shortcoming is particularly evident to tape.
The purpose of this utility model just is to overcome above-mentioned shortcoming and defect, provide a kind of take-up speed fast, save time, speed change steel tape easy to use.
Summary of the invention
In order to achieve the above object, the utility model by the chi shell, be installed in bearing seat on the chi shell, be installed in chi axle in the bearing seat, be fixed on chi core, an end on the chi axle and be fixed on the chi core that the other end is wound on the chi band that has scale that stretches out at last on the chi core from the opening of chi shell-side face and the rocking handle that is fixed on the chi axle is constituted. between rocking handle and the chi axle speed-increasing gear is installed also.Speed-increasing gear can make the rotating speed of the rotating speed of chi axle greater than rocking handle, thereby can accelerate take-up speed, save time, and is easy to use.
Speed-increasing gear can be by being fixed on speed-increasing gear seat on the chi shell, being installed in axle bed on the speed-increasing gear seat, being installed in main shaft that axle bed medial end portions and rocking handle be connected, being fixed on annular wheel on the main shaft, being installed in transition axis on the chi shell, being installed on the transition axis with the annular wheel planet gear meshed and being fixed on the chi shaft end and the central gear of planet wheel engagement constitutes.This is a kind of planet circular system speed-increasing gear.During hand rocking handle, drive shaft, annular wheel, planet wheel, central gear and chi axle make the rotation of chi core at last successively, and the chi band is packed up.Planet wheel is a kind of transition gear, and speed increasing ratio is by the ratio decision of the annular wheel number of teeth with the central gear number of teeth.That is to say that this ratio is big more, take-up speed is fast more.
Planet wheel can have 1～3.When having 3, train is stressed evenly, and transmission is more steady.
Can have the eccentric shaft shoulder on the end face of annular wheel, suit one and is had the gear ring that has scale on external tooth and its outer face on the excircle of the eccentric shaft shoulder, fixing a fixed annulus that meshes with gear ring on the speed-increasing gear seat, the outer number of teeth of the interior gear ratio gear ring of fixed annulus many 1.The relevant position has window on the speed-increasing gear seat.
If the interior number of teeth of fixed annulus is Z1, the outer number of teeth of gear ring is Z2, and Z1-Z2=1 is then arranged.That is form a tooth difference speed reducer.Fixed annulus is fixed on the speed-increasing gear seat, and the speed-increasing gear seat is fixed on the chi shell.Gear ring is driven by the eccentric shaft shoulder, and its internal tooth along fixed annulus is rolled.When gear ring rolled a week, it rotated a tooth position with respect to fixed annulus.When the annular wheel design has enough numbers of teeth, just can obtain very big ratio of gear.Such as Z1=102, Z2=101, ratio of gear then are Z1/ (Z1-Z2)=102.Should select the suitable number of teeth during design, make that gear ring just in time rotates a circle with respect to fixed annulus when the chi band is all pulled out the chi shell.Because have scale on the outer face of gear ring, when the chi band was pulled out, its scale just can reveal on the window of gearbox adapter, had realized the function that length can show on the chi shell in addition.
Speed-increasing gear also can be installed in axle bed on the speed-increasing gear seat, be installed in main shaft that axle bed medial end portions and rocking handle be connected, is fixed on the annular wheel on the main shaft and is fixed on the chi shaft end and the outer rotor of annular wheel engagement is constituted by being fixed on speed-increasing gear seat, off-centre on the chi shell.This is a kind of interior engagement train speed-increasing gear.During hand rocking handle, drive shaft, annular wheel, outer rotor and chi axle make the rotation of chi core at last successively, and the chi band is packed up.Speed increasing ratio is by the ratio decision of the annular wheel number of teeth with the outer rotor number of teeth.That is to say that this ratio is big more, take-up speed is fast more.The axle bed of this structure is eccentric to be installed.
Speed-increasing gear also can be installed in axle bed on the speed-increasing gear seat, be installed in main shaft that axle bed medial end portions and rocking handle be connected, is fixed on the gear wheel on the main shaft and is fixed on the chi shaft end and the pinion wheel of gear wheel engagement is constituted by being fixed on speed-increasing gear seat, off-centre on the chi shell.This is a kind of external toothing train speed-increasing gear.During hand rocking handle, drive shaft, gear wheel, pinion wheel and chi axle make the rotation of chi core at last successively, and the chi band is packed up.Speed increasing ratio is by the ratio decision of the gear wheel number of teeth with the pinion wheel number of teeth.That is to say that this ratio is big more, take-up speed is fast more.The axle bed of this structure is eccentric to be installed.
Speed-increasing gear can also be friction pulley architecture or the like.
Task of the present utility model comes to this and finishes.
The utility model provide a kind of take-up speed fast, save time, easy to use, speed change steel tape that length can show on the chi shell in addition.It can be widely used in the occasions such as construction work, athletic competition, real estate transaction, construction of water conservancy works, pavement construction.
