Abstract

The utility model provides a bent shaft for conveying movements of a toy, wherein an S-shaped or Q-shaped bent shaft [5]is folded on a shaft lever, and a Q-shaped bent shaft is further folded on a central shaft [9] of the bent shaft, the central shaft of the bent shaft is a shaft which is installed on a framework [2] and the rotation of the bent shaft depends on the central shaft, namely, a plurality of bent shafts are composite and superposed by the central shaft. The central shaft of the bent shaft of the utility model for conveying movements of a toy is composite with a plurality of bent shafts, thereby the utility model realizes the aim of outputting multiple movements by a part, and reduces numbers of parts, namely, the utility model reduces the size and reduces the electricity consumption of a toy, and reduces installing work hours simultaneously, moreover, compared with a cam, the bent shaft with the same convolution radius has larger eccentric magnitude, and using the bent shaft instead of a cam can increase moving scope of a toy.

Description

The bent axle that is used for toy action output

Technical field

The utility model relates to a kind of bent axle that is used for toy action output, belong to toy or gift technical field.

Background technique

Toy, generally be that animal or anthropomorphic toy now have been designed to increasing action, the not only action of the action of toy limbs or other body parts utensil that also has on it to be loaded, and the toy everything all is by being installed in mechanical structure output in the toy, and the major part of output toy action is bent axle, cam and the connecting rod that is connected with them, rocking bar etc.The bent axle that wherein is used for toy action output is by forming after the continuous bar bending, the two kinds of structures of using that have are S shape and Ω shape at present, be equipped with 4 kinds of forms according to the installation position, be that S shape or the Ω shape that install the end has been bent axle one, or the other end that to be interpreted as an eccentric shaft be S shape and the middle part of Ω shape, the S shape or the Ω shape of installing with the middle part have been the twice bent axle, or to be interpreted as two eccentric shafts are separately two ends.(S shape bent axle is called for short the S axle, shape such as Z-shaped when the S shaft end is installed in the industry.And intermediate portion is connected like two Z-shaped end ends when installing, and the angle of two ends eccentric shaft is 180 °).The bent axle that is prior art has the twice bent axle at most, make a bent axle can only export the action of the symmetry of an action or toy both sides, when a plurality of actions of needs output, just need to install a plurality of bent axles or cam, number of spare parts to take at most that volume is big, power consumption is high, it is complicated to install.

Summary of the invention

At above-mentioned deficiency, the utility model is exactly the bent axle that is used for toy action output that a kind of exportable a plurality of actions of bent axle will be provided.

The bent axle that is used for toy action output that the utility model provides, folding has S shape or Ω shape bent axle on an axostylus axostyle, also folding has the bent axle of above Ω shape together on the central shaft of bent axle, so-called central shaft is that crankshaft installed is on frame, bent axle rotates the axle of being complied with, the shape that is the bent axle that is used for toy action output that provides of the utility model generally is to fold the bent axle of Ω shape at least on the coaxial axostylus axostyle of the installation shaft of S shape or Ω shape bent axle, and the bent axle that is used for toy action output that the utility model provides in other words is that a plurality of bent axles overlap with central shaft and are composited.

The utility model provides is used for the bent axle of toy action output, and compound a plurality of bent axles have realized that a part exports the purpose of a plurality of actions on a central shaft, have reduced number of spare parts, can dwindle the toy volume and reduce power consumption, have reduced installation work-hour simultaneously.And the bent axle of same radius of gyration is compared with cam bigger offset, useless cam and can increase the movement range of toy with bent axle.

The bent axle that is used for toy action output that the utility model provides, angle between eccentric shaft of said each bent axle and the central shaft link arm on the central axis direction projection plane is 0 °--360 °, be that eccentric shaft and the connecting line between the central shaft on each bent axle can have angle arbitrarily, to adapt to the requirement of toy action.

Description of drawings

Fig. 1 is the utility model one embodiment's a structural representation, among the figure: connecting rod on the Ω shape bent axle of 1-two ends, the 2-frame, the 3-driving gear, 4-live axle, 5-bent axle, one of Ω shape bent axle is gone up connecting rod in the middle of the 6-, connecting rod on two of Ω shape bent axle in the middle of the 7-, 8-driven gear, 9-central axis (axis of the axle of crankshaft installed on frame);

Fig. 2 is another embodiment's of the utility model a structural representation (projecting direction is identical with central axis), among the figure: 10-central shaft (Graphic Center's line intersection point), 11,15-is respectively a S shape crankshaft two end eccentric shaft, 12,13,17,18-be respectively in the middle of the bent axle of Ω shape, the 14-gear.

Embodiment

1, as shown in Figure 1, bent axle 5 is installed on frame 2, and bent axle is the bent axle of the Ω shape of installing between middle part, and promptly central shaft 9 is intermediate portions of the bent axle of this Ω shape, make two ends become the eccentric shaft of same angle, each is connected with toy two arm rocking bars through a connecting rod 1 on the eccentric shaft of two ends.On this crankshaft center axle driven gear 8 is installed, driven gear and driving gear 3 engagements, driving gear is installed on the live axle 4, and the central axes of live axle and bent axle is installed on the frame.Folded the twice bent axle on the crankshaft center axle again, twice bent axle and two ends eccentric shaft are at grade but both angles are 180 °.6,7, one connecting rods of a connecting rod 6 are installed respectively on the eccentric shaft of twice bent axle are connected the head rocking bar, another connecting rod 7 connects a shank rocking bar.

2, as shown in the figure, a bent axle being arranged, be the S shape bent axle that intermediate portion is installed, and intermediate portion has four road bent axles again.Gear 14 is installed on the central shaft 10 of this bent axle.The bending order of whole bent axle is that eccentric shaft 11 bendings in end are central shaft, fold in the drawing-45 ° bent axle 17 again and fold in the drawing 180 ° bent axle 13 again through central shaft, fold 0 ° of bent axle 15 in the drawing through central shaft, fold through central shaft that 135 ° of bent axles 12 fold the other end eccentric shaft 15 through central shaft in the drawing.

Claims (2)

1. bent axle that is used for toy action output, folding has S shape or Ω shape bent axle on an axostylus axostyle, it is characterized in that on the central shaft of bent axle also folding has the bent axle of above Ω shape together, so-called central shaft be crankshaft installed on frame, bent axle rotate complied with spool.

2. the bent axle that is used for toy action output as claimed in claim 1 is characterized in that the angle on the central axis direction projection plane is 0 ° between the eccentric shaft of said each bent axle and the central shaft link arm---360 °.
