Embodiment
Below with reference to the accompanying drawings and specific embodiment detailed description is made to the present invention.
As shown in Figures 1 to 4, the present invention includes shell support body 1, center Yao Juan mechanism 2 and measure with depending on reading tape 3.
The positive backrest sheet that shell support body 1 adopts plastic-aluminum two kinds of unlike materials to form assembles, and the tape measure support frame 12 comprising handle 11 and be fixedly connected with this handle 11, so that be hold by one hand this tape measure.
Center Yao Juan mechanism 2 is fixed on the center of tape measure support frame 12, comprises rocking handle 21, rocking handle seat 22, is fixed on interior gear cover 23 outside positive frame sheet, Xiao Jie gear 24, metal fix cover plate, the band central gear 25 of shift fork and the rotating disk core 26 for being wound around tape.
Rocking handle 21 is arranged in the screens groove of rocking handle seat 22 outside surface by the pin screens being installed in its two sides, one end, pin is parallel with the outside surface of rocking handle seat 22, make this rocking handle 21 can be that axle center freely overturns with pin; away from the outside surface of one end of pin being also installed with an impeller-hub vertical with this rocking handle 21 on rocking handle 21, so that make rocking handle 21 drive rocking handle seat 22 around the center axis thereof of rocking handle seat 22 with this impeller-hub of hand propelled.
Rocking handle seat 22 is rotatably fastened on the outside of interior gear cover 23, and the Xiao Jie gear reference column 27 be installed with inside it through interior gear cover 23 middle gear hole and central gear reference column 28, and this central gear reference column 28 is fixed on the center inside this rocking handle seat 22.
Xiao Jie gear 24 is arranged on Xiao Jie gear reference column 27, and engages each other with the toothing in interior gear cover 23, and metal fixes the top that cover plate is fixed on Xiao Jie gear reference column 27, and its surface is parallel with the end face of Xiao Jie gear 24.
Xiao Jie gear reference column 27 is contour with Xiao Jie gear 24, and this Xiao Jie gear reference column 27 top end face all flushes with the inside surface of toothing in interior gear cover 23 with the inner face of Xiao Jie gear 24, so that metal is fixed cover plate when being fixed on Xiao Jie gear reference column 27, this metal is fixed the surface that cover plate contacts with Xiao Jie gear reference column 27 top end face and is contacted with the inside surface of Xiao Jie gear 24 inner face and interior gear cover 23 toothing simultaneously, making Xiao Jie gear 24 screens be arranged on metal fixes between cover plate and rocking handle seat 22, avoid inside and outside Xiao Jie gear 24 and rock.
It is a ring-type cover plate that metal fixes cover plate, and inner edges is no more than Xiao Jie gear 24 one end near rocking handle seat 22 center so that central gear 25 can fix cover plate by this metal central through hole in insert.
Central gear 25 is arranged on central gear reference column 28, and with Xiao Jie gears meshing, and the shift fork on this central gear 25 inner face is connected with an end face clamping matching of described rotating disk core 26.
Rotating disk core 26 is in cylindric, be positioned at tape measure support frame 12, and one end is provided with the screens hole with shift fork clamping matching, opposite side end face is provided with the fixed leg be rotatably fixed on inside described backrest sheet, and this rotating disk core can stably be rotated around its central axis.
Tape 3 is wrapped on rotating disk core 26, and is stretched out by the tape extending port 13 on tape measure support frame 12.
Xiao Jie gear 24 has four groups, is evenly distributed on the inward flange of toothing in interior gear cover 23, makes the power transmission between Xiao Jie gear 24 and central gear 25 more stable.
Use hand propelled impeller-hub, then impeller-hub drives rocking handle seat around the center axis thereof of this rocking handle seat by rocking handle; rocking handle seat drives Xiao Jie gear revolve round the sun around this rocking handle seat central axis; because Xiao Jie gear engage with the toothing in interior gear cover; thus Xiao Jie gear while revolving round the sun around rocking handle seat central axis around Xiao Jie gear reference column autobiography; this Xiao Jie gear drives this central gear to rotate by engaging with central gear; and then by the shift fork drive rotating disk core rotation on this central gear inner face, reach the object of acceleration.
The number of teeth of central gear 25 is Za=25, the interior number of teeth of interior gear cover 23 is Zb=54, the number of teeth of Xiao Jie gear 24 is Zc=15, obtaining central gear 25 with interior gear cover 23 ratio of gear by planet circular system computing formula is 3.25 multiplying powers, (that is: I b/ax=1+Zb/Za=1+54/24=3.25).
Shift fork on central gear 25 inner face has two, and this shift fork is cross-sectional area is polygonal column structure, so that drive rotating disk core 26 to rotate by shift fork when central gear 25 rotates.
The upper end of tape extending port 13 is provided with two ends and is separately fixed at the sliding roller bearing of increasing on positive backrest sheet medial surface, so that when tape 3 is involved in by rotating disk core 26 by this tape extending port 13, increase sliding roller bearing automatic arranging tape 3, avoid the bending of tape 3 and be wound around chaotic.
The course of work of the present invention is: start rocking handle 21, make its with the pin of the screens groove clamping matching on rocking handle seat 22 outside surface for axle center rotates freely, and then the position of adjustment rocking handle 21, the impeller-hub be located thereon is made to be exposed at the outside surface of this rocking handle 21, promote this impeller-hub, rocking handle 21 drives rocking handle seat 22 around the center axis thereof of rocking handle seat 22 thereupon, rocking handle seat 22 drives Xiao Jie gear around the center axis thereof of rocking handle seat 22 by Xiao Jie gear reference column 27, because Xiao Jie gear 24 engages with interior gear cover 23, Xiao Jie gear 24 is axle center rotation with Xiao Jie gear reference column 27 while the center axis thereof around rocking handle seat 22, the rotation of Xiao Jie gear 24 drives the central gear 25 be connected with a joggle with it to rotate, know that the rotating speed of central gear 25 is three times of rocking handle seat 22 rotating speed by the number of teeth relation of the gear relation between planet circular system and interior gear cover 23 and central gear 25, and central gear 25 drives rotating disk core 26 to rotate by the shift fork be positioned on its inner face, and then scrolling belt 3, so the rotating speed of rotating disk core 26 is three times of rocking handle seat 22 rotating speed, and the steadiness of the setting that the inner metal of Xiao Jie gear fixes cover plate when adding Xiao Jie pinion rotation, prevent the slippage of Xiao Jie gear.
Above embodiments of the invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the scope of the invention change and improve, and all should still belong within this patent covering scope.
