Abstract

The invention discloses a child bicycle limiting headstock bowl which comprises an upper packing connected with the upper end of a front fork in a threaded mode, the front fork is arranged in a headstock pipe in a penetrating mode, a limiting upper bowl is arranged between the front fork and the headstock pipe, and a limiting upper plug is arranged between the limiting upper bowl and the upper packing. Clamping blocks matched with the clamping grooves in the upper end of the headstock pipe are symmetrically arranged on the limiting upper bowl; protrusions matched with the grooves in the upperportion of the front fork are symmetrically arranged on the inner circumference of the limiting upper plug in a protruding mode, limiting blocks are symmetrically arranged on the upper portion of thelimiting upper bowl, a rotating groove is formed between the limiting blocks, limiting lugs are symmetrically arranged on the outer circumference of the limiting upper bowl, and the limiting lugs arearranged in the corresponding rotating grooves. The child bicycle limiting headstock bowl has the advantages that the structure is reasonable and compact, handlebar limiting can be achieved, the situation that a bicycle body overturns due to the fact that the handlebar turning angle is too large is avoided, and riding safety is greatly improved.

Description

technical field [0001] The invention relates to the technical field of bicycle manufacturing, in particular to a children's bicycle limited head cup. Background technique [0002] Nowadays, children are more fond of cycling, and the sales of children's bicycles are also increasing year by year. With the improvement of economic level, the market demands more and more safety and reliability of children's bicycles. Due to the young age of children and lack of control, children often encounter situations where the steering angle of the faucet is too large and the center of gravity of the vehicle body is unstable, causing the vehicle body to overturn during the riding process. Therefore, the market derives a strong demand for a controllable rotation angle of the children's bicycle faucet. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a children's bicycle limited head cup with reasonable structure and compact struc...
