Abstract

The utility model discloses a vibration gearbox with piral power spring which has simple and lively structure, integrating a power gearbox and a vibrating case. The vibration gearbox with piral power spring is chiefly applied to the small-sized toy, which mainly comprises a housing, a rope and a band pulley, a spring, a cluster gear and an eccentric sheave. When the rope is lightly pulled for a distance, the spring can store energy and the rope is loosed, and vibration is formed.

Description

Spiral spring power vibration gear case

The utility model relates to a kind of vibration gear case apparatus that is used as power by clockwork spring.This device in, spur rope one segment distance gently after, just can make the clockwork spring storage power, unclamp rope then, will form vibration.

At present, known spiral spring power vibration gear case is to combine with two independent sectors, i.e. vibration gear case apparatus and vibration gear case shell.In addition, the grooving position often needs to mix ring set and can prevent that just rope from coming into shell in conjunction with the position because of pulling.This design structurally more complicated and also production cost higher.

The purpose of this utility model provides a kind of simple in structure lucid and lively, and parts are few, grooving Position Design uniqueness, and the vibration gear case apparatus that power gear box and vibrating bin combine as a whole, it is installing easylier, and production cost lowers greatly.

The novel purpose of the utility model is achieved in that power gear box and vibrating bin unite two into one, and reduce the needs of old gearbox-case.After spurring rope one segment distance gently, just can make the clockwork spring storage power, unclamp rope then, just drive rope sheave, gear train and eccentric wheel and rotate.The centrifugal force that eccentric wheel produced in the rotation makes the utility model vibration.In addition, the grooving position is combined by one recessed and a male member, and this design can prevent that rope from coming into the grooving joint because of pulling.

Owing to adopt such scheme, can prevent because of the pulling rope damages shell, power gear box and vibrating bin unite two into one make simple in structure.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 7 is the utility model left side view.

Fig. 8 is the utility model rearview.

Fig. 9 is that the utility model decomposes structural map.

Figure 10 is that S button of the present utility model cooperates figure with the reel gear.

Figure 11 is a vertical section of the present utility model structural map.

In Fig. 1, power clockwork spring and transmitting gear thereof are in drain pan 1c and middle sheet 1b, and rope sheave 2 and eccentric wheel 13 are respectively by power shaft 5 and output shaft 10 and transmitting

gear

5,9,10 are connected among middle sheet 1b and the face-piece 1a, like this, power section and oscillating component are about to it with three shells separately has a bigger alcove in face-piece 1a, and eccentric wheel 13 can rotate therein.

As can be seen from Figure 9, rope sheave 2, S button 7 and reel tooth 8 when rotating rope sheave 2, then are attached to the S button 7 equidirectional thereupon rotations on the same axle 5 on same power shaft 5.

In Figure 10, in the process of clockwork spring tensioning, the ratchet 7a on the S button 7 slips over the ratchet 8a of reel gear 8, and S button 7 rotates and reel gear 8 does not rotate.One end of clockwork spring is stuck among two glue post 7b of S button 7, when S button 7 rotates, the clockwork spring 6 that will curl makes clockwork spring 6 tensioning energy storage, when clockwork spring 6 opens when releasing energy, clockwork spring 6 drives 7 opposite spins to tensioning clockwork spring 6 of S button, ratchet 7a on the S button 7 blocks the ratchet 8a on the reel gear 8 at this moment, and reel gear 8 is promptly buckled 7 one rotation with S like this.

In Figure 11, can find out that reel gear 8 is by the little tooth of nibbling wheel 9 of pine engagement with it, energy is passed to gear 9, and gear 9 rotates the spool gear 11 that is engaged with by canine tooth, spool gear 11 passes shell 1b by adhering to output shaft 10, and eccentric wheel 13 direct and in the alcove (shell 1a) is connected, the rotation of spool gear 11 passes to eccentric wheel 13, because the center of gravity of eccentric wheel 13 forms vibration around output shaft 10 rotations.

Can find out that in Fig. 9 rope 3 can arbitrarily pass through any one among three grooving 1i, 1j, the 1k, because three grooving 1i, 1i, 1k are respectively at three different surfaces of shell 1a, so can adapt to the public young different requirements of toy from three different directions tension ropes 3 to gear-box.

Visible grooving 1i, 1j, 1k are combined by one recessed and a male member in Fig. 5, and this design can prevent that rope 3 from coming into grooving 1i, 1j, 1k bonding station because of pulling, thereby prevention shell or rope 3 are destroyed.

As can be seen from Figure 1, only by 2 grades of rotations, the energy storage of promptly finishing clockwork spring 6 is delivered on the eccentric wheel 13, can reduce the energy loss that causes because of transmission.Also can find out among Fig. 1, the chamber that shakes of eccentric wheel 13 is that the alcove on the shell 1a is connected by middle sheet 1b with the gear-box power section, also the power house and the vibratory chamber of gear-box are separated by middle sheet 1b, power house and vibratory chamber are joined together, both can economize in raw materials and processing cost, and during Assembling Production, few, the easy installation of operation, waster rate will reduce greatly.

Claims

1. a vibration gear case that is used as power with clockwork spring is characterized in that, with a simple lucid and lively structure power gear box and vibrating bin is combined as a whole.

2. according to the described spiral spring power vibration gear of claim 1, it is characterized in that the grooving position is to be combined by one recessed and a male member, this structure can prevent that rope from coming into the grooving joint because of pulling.
