Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the field of infant products, in particular to a footrest adjusting mechanism of a child seat. BACKGROUND
[0002] The child seat generally comprises a seat part, a backrest pivotally connected to the rear side of the seat part, and a footrest pivotally connected to the seat part. In order to make the use of the seat more convenient, the footrest is generally arranged to be rotatable between different angle positions relative to the seat part. For example, the footrest can be rotated upward relative to the seat part to an angle position substantially parallel to the seat part, or can be rotated downward relative to the seat part to a suitable inclined angle position so that the small child can rest the small leg naturally lowered when sitting on the seat part.
[0003] The conventional angle adjusting device of the footrest of the child seat generally comprises two tooth grooves respectively arranged on the opposite sides of the footrest and the seat part, a gear axially movably located between the two tooth grooves, a spring arranged between the gear and the bottom wall of the tooth groove of the footrest, and a button movable leftward and rightward relative to the seat part. One side of the button extends into the tooth groove and abuts against the gear, and the other side of the button is located outside the seat part for facilitating pressing. Under the action of the spring, the gear is engaged with the tooth grooves of the footrest and the seat part at the same time, so that the footrest and the seat part are not rotatable relative to each other, and the footrest is locked at the angle relative to the seat part. When the angle of the footrest relative to the seat part is to be adjusted, the button is pressed to push the gear to move into the tooth groove of the footrest and disengage from the tooth groove of the seat part, and then the footrest is simultaneously rotated upward / downward. When the footrest is rotated to a suitable angle, the button is released. Under the action of the spring, the gear moves to the tooth groove of the seat part again and is engaged with the tooth grooves of the footrest and the seat part at the same time, so that the footrest and the seat part are not rotatable relative to each other, and the footrest is locked at another angle relative to the seat part, thereby achieving the adjustment of the angle of the footrest relative to the seat part. The arrangement of the above conventional angle adjusting device of the footrest makes the angle adjustment operation of the footrest relatively cumbersome. SUMMARY

A gear position seat axially slidable relative to the base is installed in the base. A reset member is arranged between the gear position seat and the base. The rotating connection part is provided with an adjusting gear. The gear position seat is provided with a plurality of tooth grooves arranged at intervals in the circumferential direction and used for clamping the adjusting gear. The angle of the footrest is adjusted by clamping the adjusting gear with the tooth grooves at different positions.
[0006] The adjusting tooth is a conical tooth with high middle and low sides, and the tooth groove is a conical groove corresponding to the adjusting tooth, and the grooves of adjacent tooth grooves are smoothly connected.
[0007] The adjusting tooth is arranged on the side end face of the rotating connecting part close to the gear seat, and the tooth groove is formed on the side end face of the gear seat close to the rotating connecting part.
[0008] The adjusting tooth on the rotating connecting part is symmetrically arranged in two.

[0010] The base is mounted on the front side of the bottom of the seat part.
[0011] The base, the rotating connecting part, the gear seat and the reset member are symmetrically arranged in two.
[0012] The reset member is a reset spring, which always presses the gear seat towards the corresponding rotating connecting part.
