The invention discloses a push rod reversing four-wheel rotating orientation mechanism for a baby carriage. Comprising a push rod provided with a push rod joint at the lower end, a rear leg bracket provided with a rear leg joint at the upper end, a front leg bracket provided with a front leg joint at the upper end, a front wheel seat capable of rotating around a vertical shaft and mounted at the lower end of a front wheel bracket, a rear wheel seat capable of rotating around the vertical shaft and mounted at the lower end of the rear leg bracket, and an operating device, the push rod locking mechanism can achieve fixed buckling positioning or releasing of the push rod joint and the rear foot joint, and the front foot positioning mechanism and the rear foot positioning mechanism can achieve fixed buckling positioning or releasing of the front foot support and the front wheel seat and fixed buckling positioning or releasing of the rear foot support and the rear wheel seat respectively. The push rod joint rotates to drive the front foot positioning mechanism and the rear foot positioning mechanism to be in reverse linkage through the front foot transmission mechanism and the rear foot transmission mechanism, the operation device can drive the push rod locking mechanism to move, the frame joint structure is simpler and more compact, and the strength of the frame joint and the whole vehicle is improved.
本发明公开了一种婴儿车推杆换向四轮旋转定向机构,包括下端设有推杆关节的推杆、上端设有后脚关节的后脚支架、上端设有前脚关节的前脚支架、能绕竖直轴转动的安装于前轮支架下端的前轮座、能绕竖直轴转动的安装于后脚支架下端的后轮座和操作装置,推杆锁定机构能实现推杆关节和后脚关节固定扣合定位或脱扣,前脚定位机构和后脚定位机构分别能实现前脚支架与前轮座以及后脚支架与后轮座固定扣合定位或脱扣,推杆关节转动分别通过前脚传动机构和后脚传动机构带动前脚定位机构和后脚定位机构反向联动,操作装置能够带动推杆锁定机构运动,本发明使车架关节结构更为简单、紧凑,提高了车架关节和整车的强度。
