The invention discloses a quick-adjustable double-deceleration child tricycle front driving wheel. The quick-adjustable double-deceleration child tricycle front driving wheel comprises a pair of coverbodies which are relatively arranged, a pair of cover body bolts, a pair of power fluted discs which are rotatably arranged in the cover bodies correspondingly, a driving assembly which is arranged among the power fluted discs and a front cover and comprises a pair of driving shaft pipes, a driving clamping block, a driving clamping column, a driving screw, a traction column head, a pair of limiting clamping springs and a pressure spring, an adjusting assembly which comprises an adjusting pulling wire, an adjusting screw cylinder, a locking sliding block, a sliding block spring, a sliding block blocking piece and a blocking piece bolt, and a pair of pedal assemblies. The child tricycle front driving wheel is among a primary deceleration mode, an idle position mode, a secondary deceleration mode and a full speed mode. The riding mode can be freely selected by a user. Appropriate application for children of different ages can be achieved, and security is high.
Description
technical field [0001] The invention relates to a children's tricycle, more precisely, it is a front drive wheel of a quick-adjustable double-reduction children's tricycle. Background technique [0002] Children's tricycle is a kind of common children's toy, and usually children utilize feet to push the pedals on the front wheels to make the tricycle travel. The rear portion of the children's tricycle on the market is equipped with an operating lever, which is convenient for parents to operate. Yet when this tricycle advances, the child's pin can only rotate with the wheel, and the pedal often hits the child's pin, causing inconvenience and injury. In addition, the running speed of the existing children's tricycle cannot be adjusted, and cannot adapt to children of different athletic abilities and different ages. Contents of the invention [0003] The invention mainly solves the technical problems existing in the prior art, thereby providing a front drive wheel of a quic...
