Abstract

The utility model relates to a swing mechanism for an animal toy. The inner part of a main shell body is provided with a suit of worm wheel transmission mechanism, and a worm wheel shaft is provided with an eccentricity wheel disc; one position of the outer wall of the main shell body, which is near the eccentric wheel, is provided with a convex post capable of matching with a T-shaped deflector rod, the T-shaped deflector rod is provided with a gap capable of being inserted and matching with the eccentricity wheel disc, and the T-shaped deflector rod can deflect the swing shell body to swing left and right. The swing mechanism has the advantages of scientific organizational design, simple and reasonable structure, and flexible and reliable action. The utility model can be applied to the animal toy and then enables the four limbs to be more flexible and active so as to satisfy the requirement of change that the animal toy prearranges various action; furthermore, the change of the center of gravity of the body can self-adjust so that real effect just like a real animal can be achieved.

Description

The toy for animal swing mechanism

The utility model relates to a kind of mechanical pendulum actuation mechanism, especially a kind of this swing mechanism can being arranged within the mechanical animal, the toy for animal swing mechanism that these machinery animal head and the tail are waved relatively.

At present, the general common on the market all kinds of moulding animals that supply the consumer to admire, as: cat, dog etc. are usually designed to single static state.Along with the lifting day by day of the progress of science and technology and consumer's taste, this toy for animal that is static shape can not satisfy consumer's requirement.Therefore, manufacturer is popular and consumer's needs, with such moulding animal by simple static state in the past, be designed to the movable all kinds of moulding machinery animals of a kind of tool, to make the no longer only just simple static appreciation of this machinery animal, it is movable to make great efforts to make such mechanical animal to have as the life.Improved the enjoying nature of this type toy greatly.Yet, though these movable mechanical toy for animal can be brought into play the function of its action.But the component parts that mechanical toy for animal inner moveable is done mechanism is too many, and structure is too complicated, as long as arbitrary member of its inside has problems, just can influence the normal operation of entire mechanism.The consumer often perplexs for this reason.The manufacturing cost of this mechanical toy for animal is also higher.

The purpose of this utility model is the deficiency at the mechanical pendulum actuation mechanism existence of above-mentioned mechanical toy for animal, a kind of simple in structure, flexible movements are provided, and can swing and adjust the gravity-center-change of its health automatically with this swing mechanism, so reach lively especially as the toy for animal swing mechanism real movement thing, that be applicable to the inner installation of mechanical toy for animal.

Toy for animal swing mechanism of the present utility model comprises: main casing and swing housing is characterized in that: be provided with a cover Worm wheel transmission mechanism in the main casing; The centre position of worm-wheel shaft sheathed one eccentric wheel disc; The power of worm gear come in the worm screw that cooperates with it; The nearly eccentric wheel of main casing outer wall place is provided with a projection that can cooperate with T type driving lever at least, and the cross bar of described T type driving lever is provided with a microscler groove that can be placed on the projection, the cross bar side of T type driving lever be provided with one can with the breach of eccentric wheel disc outer rim inserting on the worm-wheel shaft; The montant end of T type driving lever is provided with a protruding pin; The one passive bar that has a long groove vertically is set on the shell wall on swing housing nearly main casing side, and the long groove kink on the passive bar is on the protruding pin of T type driving lever montant end.

Toy for animal swing mechanism design principle of the present utility model is: utilize the Worm wheel transmission mechanism be arranged in the main casing, and be arranged on cooperating of eccentric wheel disc and T type driving lever on the worm-wheel shaft, realize swinging swinging of housing.This swing mechanism is installed on the inner set skeleton of mechanical animal, when eccentric wheel disc rotates on the worm-wheel shaft,, makes T type driving lever make reciprocally swinging along the microscler groove on its cross bar by cooperating of this off-centre wheel disc and the set breach of T type driving lever; The protruding pin of T type driving lever montant end then cooperates with long groove on the swing housing vertical passive bar, makes to swing housing and swing.

Toy for animal swing mechanism design science of the present utility model, simple and reasonable for structure, flexible movements are reliable.It is applied to toy for animal can make its major beat lively more flexibly, to satisfy the needs of the default exercises variation of toy for animal, rely on this swing mechanism simultaneously, the arm (swing housing) that can make toy for animal swings and adjusts the gravity-center-change of its health automatically, and then reaches just like lively as the real animals.

The concrete structure of the utility model toy for animal swing mechanism is provided in detail by the following drawings and embodiment.

Fig. 1 is a toy for animal swing mechanism perspective exploded view;

Fig. 2 is the structural representation of toy for animal swing mechanism;

Fig. 3 is a toy for animal swing mechanism application example schematic diagram.

Embodiment: can be clear that from Fig. 1 and Fig. 2, the toy for animal swing mechanism has a main casing 10, be provided with a cover Worm wheel transmission mechanism 1 in the main casing 10, the worm-wheel shaft 11 of Worm wheel transmission mechanism 1 is provided with eccentric wheel disc 12, worm gear 13, flute profile wheel 14 and disk 15, eccentric wheel disc 12 is arranged on the middle part of worm-wheel shaft 11, worm gear 13, flute profile wheel 14 are arranged on an end of worm-wheel shaft 11, and disk 15 is arranged on the other end of worm-wheel shaft 11.The worm shaft 16 of Worm wheel transmission mechanism 1 is perpendicular with worm-wheel shaft 11, and worm shaft 16 is provided with worm screw 17, and worm screw 17 is meshed with worm gear 13, and worm screw 17 is driven by the motor (not shown).Described disk 15 outer rims are provided with a convex body 151 at least, when disk 15 rotates, convex body 151 on it, and the plural sawtooth 141 on the flute profile wheel 14 just can contact with two signal elements 20,21 respectively, that is: the convex body 151 on the disk 15 contacts with signal element 20, plural sawtooth 141 and signal element 21 on the flute profile wheel 14 are made various default actions with these four limbs 51 that drive mechanical toy for animal, as: actions such as shaking hands, squat down, stretch.The nearly eccentric wheel disc of main casing 10 place's walls 12 places are provided with a projection 18 at least, projection 18 is plugged in the microscler groove 31 of cross bar of T type driving lever 30, the vertical montant end of T type driving lever 30 is provided with a protruding pin 32, T type driving lever 30 cross bar sides also are provided with a breach 33 that can snap in eccentric wheel disc 12 outer rims, when eccentric wheel disc 12 rotates, T type driving lever 30 cooperates according to the microscler groove 31 of its cross bar and last projection 18, and the cooperating of cross bar side breach 33 and eccentric wheel disc 12 outer rims, make T type driving lever 30 in the scope of the set microscler groove 31 of cross bar, make reciprocally swinging.
