Abstract

The utility model discloses an inertia toy. Members of a gear transmission device, an inertia wheel, etc. are arranged in a toy outer shell. The inertia wheel uses the gear transmission device to connect and drive toy wheels, thereby, the toy wheels are rotated under the action of external force, the inertia wheel is driven to rotate to do uniformly variable motion to generate inertia force, and the inertia toy is pushed by the inertia force to maintain a definite motion state.

Description

A kind of Inertia toy

The utility model relates to a kind of toy for children, and is especially relevant with its structure of the object for appreciation with inertia.

Common toy for children is divided into electronic and clockwork spring control starts two kinds, all need when playing to connect power supply or tighten clockwork spring at every turn, the noninertia of toy own, whole course of action is entirely by power supply and clockwork spring control, and can not keep certain motion state by the toy its own inertial, influence virgin child's excitement.

The purpose of this utility model is to provide a kind of Inertia toy, by the inertia that toy self possesses, keeps the certain movement state of toy, increases child's the excitement of playing.

For reaching above-mentioned purpose, the utility model comprises toy case and is arranged on gear drive in the shell and member such as flying wheel, form an inertia roller box in the shell, flying wheel is arranged in the inertia roller box, and be fixed on the inertia wheel shaft, a movable lasso of plastics that matches with the diameter of axle is equipped with at inertia wheel shaft two ends respectively, be used for reducing the friction of axle head at rotary course, also can lubricate, between flying wheel and the ancestral's transmitting gear spring is housed on the inertia wheel shaft, the copper band cover is equipped with in ancestral's transmitting gear outside, by the fixing moving position of flying wheel and ancestral's transmitting gear of flying wheel casing; The tumbler gear of matched in clearance engagement on the one-level driven shaft in ancestral's transmitting gear and the gear drive, with integrated gear of tumbler gear and the gears engaged that is fixed on the secondary driven shaft, be fixed on the gears engaged of matched in clearance on another gear on the secondary driven shaft and the one-level driven shaft, integrated another gear of gear and the driving wheel engagement that is fixed on the driving shaft with matched in clearance on this one-level driven shaft, driving shaft is fixedly connected with the toy wheel again, thus by gear drive driving coupling flying wheel and toy wheel.

After adopting said structure, the utility model self has the inertia function, and under the effect that is subjected to external force, the toy wheel turns drives the driving wheel running, connects by gear drive to be transmitted in ancestral's transmitting gear, makes flying wheel begin to rotate; This moment, toy can be transmitted in driving wheel again because of the rotation of flying wheel, makes the toy wheel turns, promptly utilizes the inertia function of toy to keep certain motion state if external force disappears, and increased child's the interest of playing.

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

Fig. 1 is the utility model embodiment sectional perspective exploded view;

Fig. 2 is the utility model embodiment part plan schematic diagram;

Fig. 3 is the utility model embodiment profile schematic diagram.

Consult Fig. 1-3, the utility model is that embodiment is illustrated with the inertia dolly, and the utility model comprises shell 7 and is arranged on gear drive in the shell 7 and member such as flying wheel 11.Form an inertia roller box 1 in the shell 7, flying wheel 11 is arranged in the inertia roller box 1, and be fixed on the inertia wheel shaft 12, a movable lasso 14 of plastics that matches with the diameter of axle is equipped with at inertia wheel shaft 12 two ends respectively, to reduce the friction of axle wall in rotary course, between flying wheel 11 and the ancestral's transmitting gear 13 spring 15 is housed on the inertia wheel shaft 12, copper band cover 16 is equipped with in ancestral's transmitting gear 13 outsides, is arranged on the moving position that fixes flying wheel 11 and ancestral's transmitting gear 13 on the inertia roller box 1 by inertia wheel shaft 12.Gear 6 engagements that move of matched in clearance on the one-level driven shaft 32 in ancestral's transmitting gear 13 and the gear drive, with tumbler gear 6 integrated gears 5 and gear 42 engagements that are fixed on the secondary driven shaft 41, be fixed on gear 31 engagements of matched in clearance on gear 4 and the one-level driven shaft 32 on the secondary driven shaft 41, with integrated gears 3 of gear 31 and driving wheel 2 engagements that are fixed on the driving shaft 21, the wheel transmission that is fixedly connected behind driving shaft 21 and the toy car.

Under external force, wheel begins to rotate behind the toy car, drive driving wheel 2 runnings, by the multi-stage gear transmission flying wheel 11 is rotated, and do uniform variable motion, and producing centripetal force and inertia force when so rotating, dolly is subjected to the promotion of inertia force can do even change speed linear motion, and keep the certain motion state of dolly, increase child's excitement.
