Abstract

The invention relates to an adjustable front fork structure of a children bicycle. The adjustable front fork comprise a handlebar, shoulder covers, a front fork, and tightening screws, wherein fork legs comprise four pipes, the four pipes are separated into two groups, each group of pipes respectively comprise an upper pipe and a lower pipe, the lower end of each upper pipe is inserted into the upper end of the corresponding lower pipe, each shoulder cover comprises a shoulder cover body part, a fork leg upper pipe inserting opening and a head pipe inserting opening, each head pipe inserting opening is used for connecting the corresponding shoulder cover and a head pipe of the children bicycle, the upper shoulder cover is fixedly connected with the two upper pipes, the lower shoulder cover is fixedly connected with the two lower pipes, the upper shoulder cover is fixedly connected with vertical pipes through a locking device, and the lower shoulder cover is detachably and fixedly connected with the fork legs by a locking device. The adjustable front fork structure of the children bicycle has the advantages that by adopting an argon arc welding method, a transverse pipe which is gripped by hands in the riding process and the two parallel vertical pipes are directly connected into a whole; the assembly procedure is reduced, and the fork legs are adjusted up and down by the handlebar and are locked by the fork leg, the shoulder covers and the tightening nuts, so as to adjust the height of the handlebar.

Description

technical field [0001] The invention relates to a front fork structure of a children's bicycle, in particular to an adjustable front fork structure of a children's bicycle which can adjust the height of the handlebar through the vertical adjustment of the handlebar and the locking of the front fork shoulder cover fastening screw. Background technique [0002] At present, the front forks of children's bicycles on the market are double-shouldered, which are rare in ordinary types. The front forks and handlebars are made of separate structures. The above products have the following problems in the manufacturing process and finished products: [0003] 1. The size of the front fork is fixed and cannot be adjusted. It is necessary to adjust the height of the handlebar through the length of the head tube and the front fork stem tube, and the height adjustment size is limited. [0004] 2. Both the front fork and the handlebar are of split structure, and the handlebar is hung and loc...
