Abstract
The utility model relates to a spring power cochain gearbox, which comprises a casing, an input shaft, an output shaft and a plurality of gears, wherein, the casing comprises a spring recess which is arranged near the side wall of the casing; the input shaft which is connected with a spring is supported on the side wall of the casing, and one end of the input shaft is fixed with a turn knob; the gears are arranged between the input shaft and the output shaft; a fastening Fixing mechanism and a matching fixing mechanism which are arranged at the tail part of the spring are arranged on the recess wall of the spring recess. For the slow cochain type plastic gearbox device, the spring can store energy after turn knob is screwed in for a plurality of circles, and then powerful but not noisy rotating power can be released by loosening the turn knob. The utility model can output greater power, and can be more extensively applied in toy industry.
Description
The utility model relates to a kind of low-gear case apparatus that is used as power by clockwork spring, and in this device, upward moving turn-knob just can make the clockwork spring stored energy after a few, unclamps turn-knob then, will emit rotational power.
At present, the known chain spiral spring power gear-box clockwork spring afterbody of going up at a slow speed can only exist at shell or with roundlet head mould formula in fastening, can not allow the design of two kinds of mode switch.In addition, limit based on specification, the known tiny general outputting power of chain spiral spring power gear-box of going up is less, so it is heavier or need on the toy of very strong driving force to be applied to build.In addition, go up chain spiral spring power gear-box at a slow speed and lower rotational velocity with wig-wag, this design noise is bigger, and children's sense of hearing is constituted certain influence.
The purpose of this utility model provides a kind of spiral spring power cochain gear-box.This is that a kind of output rotatory force is powerful, but the noise-free chain gear box device of going up at a slow speed.Therefore, it is heavier or need on the toy of very strong driving force that this device can more widely be applied to build, and the quiet design of this toy more can be lowered the influence to children's sense of hearing greatly.In addition, the shell of this device can allow clockwork spring exist in the shell pattern or with roundlet head mould formula with fastening.
The purpose of this utility model is achieved in that
A kind of spiral spring power cochain gear-box is characterized in that, comprising:
Shell is included near the clockwork spring alcove that is provided with its sidewall;
The input shaft that links to each other with clockwork spring is bearing on the side wall of outer shell, and the one end is fixed with turn-knob;
Output shaft;
Be arranged on a plurality of gears between described input shaft and the output shaft,
The fastening fixed mechanism of clockwork spring afterbody is set respectively on the alcove wall of clockwork spring alcove and cooperates fixed mechanism.
Shell has the button bit design of a uniqueness can allow clockwork spring exist in the shell pattern with roundlet head mould formula or with fastening.Clockwork spring exists with roundlet head mould formula, the superfluous strength of twisting turn-knob can be eliminated superfluous strength with the little round end method of skidding, and is exempted to damage gear box device.When clockwork spring with fastening when the shell pattern exists, upward moving turn-knob can allow gear-box store more macro-energy.The clockwork spring alcove space that increases in the gear box device can hold the more clockwork spring of macro-energy, thereby bigger output rotatory force can be provided, and is applied on the more large-scale toy.In addition, the sound that rotates is lowered in reaching that the film gear in the gear box device can slow down the Gear combination rotational velocity, thereby the situation of noisy ear occurs.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model perspective tectonic maps.
Fig. 2 is the perspective tectonic maps that the utility model does not have face-piece.
Fig. 3 is the utility model exploded perspective view.
Fig. 4 is S button of the present utility model and reel gear matched figure.
Fig. 5 is that the utility model clockwork spring afterbody becomes roundlet head shapes figure.
Fig. 6 is that the fastening of the utility model fastening formula clockwork spring afterbody is at the shell plan.
In Fig. 1, Fig. 2, Fig. 3, Fig. 4, the turn-knob 11 of turning clockwise blocks the clockwork spring 13 that is positioned at clockwork spring alcove 1a1 with two glue post 2a as the main shaft 10 close-fitting S button 2 of input shaft and turns clockwise, make clockwork spring 13 tensionings, the ratchet 2b and 3 divergence (-cy)s of reel gear of S button 2 when S button 2 turns clockwise are not so drive reel gear 3 and other gear movement.
In Fig. 5, the fasteners 13a ' as fastening fixed mechanism of fastening formula clockwork spring afterbody 13a fastening on shell 1a, fasteners 13a ' fastens with the fastening formula clockwork spring afterbody shown in this figure.Going up moving turn-knob can allow gear-box store more macro-energy.In Fig. 6, clockwork spring afterbody 13b is designed to little rounded shape, little rounded shape can form by folding described clockwork spring end, uniform one or more groove 13b ' on the clockwork spring alcove 1a1 internal face, its shape is corresponding with the clockwork spring afterbody 13b of little round end, in the time of in being subjected to certain power, clockwork spring afterbody 13b can be engaged in the groove 13b ', when being subjected to bigger power, clockwork spring afterbody 13b can cross and skid off groove 13b ', thereby is exempted to damage gear box device.
In Fig. 3, behind clockwork spring 13 complete tensioning storage of potential energy, turn-knob 11 promptly stops the rotation, clockwork spring 13 extensions of unclamping turn-knob 11 back tensionings will make the ratchet 2b that blocks clockwork spring be rotated counterclockwise, ratchet 2b drives reel gear 3 and does rotation in the same way simultaneously, reel gear 3 will drive the excessive gear 4 that meshes with reel gear 3 simultaneously and turn clockwise, excessive gear 4 will drive excessive gear 5 and be rotated counterclockwise, simultaneously will drive excessive gear 6 turns clockwise, excessive gear 6 will drive the film gear 7 that meshes with it and be rotated counterclockwise, cushion compound 8 by center hole and film gear 7 close-fittings is rotated counterclockwise, the both wings 8a of cushion compound 8 opens the film friction wall 1a2 friction with shell 1a in the process of rotation, speed slows down and quiet effect to reach, and clockwork spring 13 is gently released energy.
Be rotated counterclockwise with the spool gear 9 that excessive gear 4 meshes simultaneously in this.The little axle 12 as output shaft of device in spool gear 9 together is rotated counterclockwise with spool gear 9, thereby takes rotation strength out of.When other toy accessories cooperate little axle 12 to rotate, can drive the toy activity.
As another embodiment of the present utility model, main shaft 10 and little axle 12 also can be uneven, by the umbrella gear even flowing.
As another embodiment of the present utility model, output shaft can have a plurality of, can be parallel, also can be not parallel, and in order to drive toy accessory in different direction or angle rotation.
