Abstract
The utility model discloses a driving device of a children tricycle, which is used for driving wheels. The utility model comprises a wheel boss, a crank, a scarf joint plate, a gasket, a connecting pipe and a front fork, wherein, the wheel boss is arranged in a wheel; a through hole with a bearing rib is arranged in the center of the wheel boss; the through hole is embedded and fixed on the scarf joint plate, forming one non-circular scarf joint hole; one end of the crank is fixedly connected with a scarf joint sheet; after the crank penetrates through the gasket and the connecting pipe; the other end is fixedly connected with pedals; the connecting pipe is fixedly connected with an inserting pipe of a front fork. When in use, the crank and the scarf joint sheet are correspondingly embedded in the scarf joint hole for butting with the scarf joint plate; the connecting pipe is fixedly connected with the front fork, the crank, the driven wheel boss and the wheel; because of the middle part of the crank is formed in the way, the damage is difficult; thereby, the utility model can avoid that the wheel boss and the wheels do not interlocked caused slipping run idle; defective products are different to generate; compared with an ordinary appliance, the cost is lower, the assembly is easy and convenient, and the market competitiveness is strong.
Description
Technical field
The utility model relates to a kind of child's tricycle, refers to a kind of actuating device of child's tricycle especially.
Background technology
The actuating device of known child's tricycle, all be to be fixed in crank respectively and the interlock wheel with two pedals, and common form be with the crank stage casing directly in the mode of inserts when the wheel hub ejection formation, be shaped on the wheel hub, and crank two segmentum laterales set firmly pedal again, drive front-wheel by this, but therefore mode crank stage casing is the linear round bar, QC was bad when the crank stage casing was easy to because of ejaculation, and after using the several months, promptly damage, cause the crank slippage and dally, can't interlock wheel hub and wheel, still more, molding mode with the inserts ejaculation, be easy to produce defective products, and cause the cost height, market competitiveness landing.
The utility model content
The purpose of this utility model is to provide a kind of crank to be difficult for the child's tricycle actuating device of slippage idle running.
For achieving the above object, solution of the present utility model is: a kind of child's tricycle actuating device, it comprises wheel hub, crank, scarfing plate, pad, connection pipe and front fork, cooperate wheel to implement, wherein, wheel hub is located in the wheel, wheel hub central authorities establish a perforation with fin, the scarfing plate build-in is in the non-circular boarding hole of perforation internal shaping, the affixed scarfer that is embedded in boarding hole and is butted on scarfing plate of crank one end, in the affixed pedal of the other end, connection pipe is provided with the intubate of affixed front fork behind crank cross-under pad and the connection pipe.
After adopting said structure, owing to form non-circular boarding hole in the scarfing plate perforation, the affixed boarding hole that is embedded in of the scarfer of crank, the moulding by this way of crank stage casing is not easy to damage and causes its slippage idle running, and then can't interlock wheel hub and wheel, and be not easy to produce defective products, compare with the product of commonly using, cost is lower and assembling is easy, convenience, and the market competitiveness is strong.
