Problems solved by technology

When the tricycle is pushed by the parents, the pedals will also rotate at the same time, which is easy to hit the children's legs and feet, and the children's feet can only be suspended in the air, which is less comfortable
In addition, for active children, the speed of the tricycle may be too fast, prone to overturning, causing accidental injuries

Abstract

The invention discloses a child tricycle front wheel with a shaft type adjusting structure. The child tricycle front wheel comprises a hub, a pair of pedal crankshafts, a drive assembly used for driving the hub and a deceleration assembly used for reducing the rotation speed transmitted from the drive assembly to the hub, wherein the drive assembly comprises an adjusting device and a drive device,and the adjusting device axially adjusts the drive device, so that the drive device drives the hub in an idle mode or a deceleration mode or a synchronous mode. The child tricycle front wheel with the shaft type adjusting structure has the following beneficial effects that a user can set the working mode of a tricycle randomly according to requirements, the child tricycle front wheel is suitablefor being used by children at different ages, and the safety and usability of the child tricycle are greatly improved.

Description

[0001] This application is a divisional application of the invention patent application with the application number 201610897771.4, the invention name is the front wheel of the shaft-adjustable children's tricycle, and the application date is October 13, 2016. technical field [0002] The invention relates to a children's tricycle, more precisely, a front wheel of a children's tricycle with a shaft-type adjustment structure. Background technique [0003] Existing children's tricycles generally adopt a pedal-driven front wheel without a braking system. When the tricycle was promoted by the parents, the pedals would also rotate simultaneously, which would easily hit the children's legs and feet, and the children's feet could only be suspended in the air, with poor comfort. In addition, for active children, the speed of the tricycle may be too fast, which is prone to overturning and causing accidental injuries. Contents of the invention [0004] The invention mainly solves t...
