Abstract
The utility model which relates to an inertia driver of walking toys is used to solve the problem that the teeth beating phenomenon can happen between transmission variable speed gears of the present inertia drivers, and the gears are not durable or easily destroyed, or the arranged clutch which is complex in structure and high in price has a convex reset spring base. The point of the technical proposal is that the utility model comprises a shell frame, a walking driving axis which is rotatably matched with the shell frame, transmission variable speed gears and an inertia wheel, wherein, the walking driving axis is rotatably connected with the inertia wheel through the transmission variable speed gears, and the utility model is characterized in that the inertia wheel is fixed with an internal ratchet ring, and the wheel axis of the inertia wheel is rotatably matched with a gear and a decorum part of a catch cam wheel, and the catch cam wheel is matched with the internal ratchet ring, and the inertia wheel is rotatably connected with the transmission variable speed gears through the gear of the decorum part.
Description
Technical field
The utility model relates to the workpiece of toy for children, specifically is meant a kind of inertia starter that drives the toy of walking by inertia force.
Background technology
By the toy of inertia force driving walking, as being used to power toy car etc., be a class of toy for children.The toy that drives walking by inertia force drives by its inertia starter, inertia starter generally is made of shell frame and the propel driving shaft, transfer motion speed changing gear and the flying wheel that are rotatably assorted on the shell frame, wherein propel driving shaft is in transmission connection by transfer motion speed changing gear and inertia crop rotation, flying wheel is the parts of inertia as walking driving power that rotate, on the propel driving shaft road wheel etc. can be installed, this inertia starter just like No. 96250210.3 disclosed a kind of Inertia toy of Chinese patent is.The shortcoming that this inertia starter exists be when running toy run into intransitable barrier or other reason, when propel driving shaft stops operating suddenly, the rotary inertia of flying wheel can make between the transfer motion speed changing gear to produce beats the tooth phenomenon, transfer motion speed changing gear is not durable or damages.People are provided with clutch again on the inertia wheel shaft for this reason, promptly between the jaw clutch that is slidingly matched on the inertia wheel shaft, jaw clutch and shell frame, be provided with return spring, when the propel driving shaft resistance is excessive, clutch separates the clutch end of flying wheel automatically, makes flying wheel be in idling conditions.But the clutch configuration of this set on the inertia wheel shaft is comparatively complicated, and cost is higher, and the outer inertia wheel shaft place of shell frame also should establish the return spring seat of an evagination.
Summary of the invention
To beat the tooth phenomenon in order producing between the transfer motion speed changing gear that overcomes existing inertia starter, not to be durable or fragile, or the clutch configuration that is provided with is comparatively complicated, cost is higher, the defective of return spring seat that evagination is arranged, the purpose of this utility model provides a kind of inertia starter of improved running toy, can overcome the defective of prior art.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of inertia starter of running toy, constitute by shell frame and the propel driving shaft, transfer motion speed changing gear and the flying wheel that are rotatably assorted on the shell frame, wherein propel driving shaft is in transmission connection by transfer motion speed changing gear and inertia crop rotation, it is characterized in that: be fixed with a handle ratchet wheel circle on the described flying wheel, the fit part of a gear and pawl wheel is rotatably assorted on the wheel shaft of flying wheel, pawl wheel cooperates with the handle ratchet wheel circle, and flying wheel is in transmission connection by the gear and the described transfer motion speed changing gear of fit part.
Above-mentioned transfer motion speed changing gear can have any suitable transmission gear shift progression.
The beneficial effects of the utility model are: constitute isolator because pawl wheel cooperates with the handle ratchet wheel circle, when driving propel driving shaft with manpower and rotate, the rotation of pawl wheel promotion handle ratchet wheel circle makes the flying wheel inertia that rotates; After manpower unclamps, the handle ratchet wheel circle by and pawl wheel between frictional force drive pawl wheel and rotate, to drive propel driving shaft; When the propel driving shaft resistance is excessive when surpassing frictional force between handle ratchet wheel circle and the pawl wheel, the handle ratchet wheel circle skids on pawl wheel automatically, makes flying wheel idle running, avoids producing between the transfer motion speed changing gear phenomenon of beating tooth, the service life of raising transfer motion speed changing gear.The utlity model has the advantage of the return spring seat that structure is comparatively simple, cost is lower, do not have evagination.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the cross-sectional schematic of an embodiment of the utility model.
Fig. 2 is the A-A cross-sectional schematic (flying wheel that only draws, handle ratchet wheel circle and pawl wheel) of Fig. 1.
Among the figure: 1, shell frame; 2, propel driving shaft; 3 and 4, transfer motion speed changing gear; 5, flying wheel; 6, handle ratchet wheel circle; 7, wheel shaft; 8, gear; 9, pawl wheel; 10 and 11, long ratchet; 12 and 13, road wheel.
The specific embodiment
With reference to Fig. 1 Fig. 2, the inertia starter of this walking toy, constitute with flying wheel 5 by shell frame 1 and the propel driving shaft 2 on shell frame 1 of being rotatably assorted, transfer motion speed changing gear 3,4 etc., wherein propel driving shaft 2 is in transmission connection with flying wheel 5 by transfer motion speed changing gear 3,4 etc., it is characterized in that: be fixed with a handle ratchet wheel circle 6 on the described flying wheel 5, the fit part of a gear 8 and pawl wheel 9 is rotatably assorted on the wheel shaft 7 of flying wheel 5, pawl wheel 9 cooperates with handle ratchet wheel circle 6, and flying wheel 5 is in transmission connection with described transfer motion speed changing gear 4 by the gear 8 of fit part.In addition, transfer motion speed changing gear 3,4 etc. constitutes three grades of transmission shifting mechanisms; Pawl wheel 9 is to cooperate with handle ratchet wheel circle 6 by two on it long ratchets 10,11; Propel driving shaft 2 also is equipped with two road wheels 12,13.
During use, when driving propel driving shaft 2 rotations with manpower, behind the process transfer motion speed changing gear 3,4 etc., pawl wheel 9 promotes handle ratchet wheel circles 6 by two long ratchets 10,11 and presses B to rotation, makes flying wheel 5 produce rotary inertia by B to rotation process; After manpower unclamps, handle ratchet wheel circle 6 by and long ratchet 10,11 between frictional force drive pawl wheel 9 and rotate, drive propel driving shaft 2 rotations by transfer motion speed changing gear 3,4 etc.; When propel driving shaft 2 resistances are excessive when surpassing frictional force between handle ratchet wheel circle 6 and the pawl wheel 9, handle ratchet wheel circle 6 skids on long ratchet 10,11 automatically, and flying wheel 5 is dallied.
Claims (2)
1. the inertia starter of a running toy, constitute by shell frame and the propel driving shaft, transfer motion speed changing gear and the flying wheel that are rotatably assorted on the shell frame, wherein propel driving shaft is in transmission connection by transfer motion speed changing gear and inertia crop rotation, it is characterized in that: be fixed with a handle ratchet wheel circle on the described flying wheel, the fit part of a gear and pawl wheel is rotatably assorted on the wheel shaft of flying wheel, pawl wheel cooperates with the handle ratchet wheel circle, and flying wheel is in transmission connection by the gear and the described transfer motion speed changing gear of fit part.
