The invention discloses a gathering type folding frame which comprises a plurality of supporting mechanisms and wheels correspondingly arranged below the supporting mechanisms, a center folding mechanism is arranged between the supporting mechanisms, a transverse folding mechanism is arranged in the deflection direction of the frame, and a handle is arranged on one side of the advancing direction of the frame. After the central folding mechanism is folded, the supporting mechanism gathers towards the central folding mechanism. A gathering type folding mode is adopted, folding can be conducted in the length direction and the width direction at the same time after folding, the folding method is simple, use is convenient, the size is small after folding, no acute angle structure exists, and potential safety hazards do not exist. The connecting rod adopts a three-section bending design, and an arch structure is formed at the central supporting mechanism, so that the connecting rod has good bearing capacity and system stability. Due to the fact that the device is good in overall stability and bearing capacity, a folding mechanism in the length direction can be omitted, the overall weight of the frame is reduced, and carrying is convenient.
本发明公开了一种聚拢型折叠车架,车架包括若干支撑机构和对应设置在支撑机构下的轮子,支撑机构之间设有中心折叠机构,车架偏转方向上设有横向折叠机构,车架行进方向一侧设有拉手;中心折叠机构折叠后,支撑机构向中心折叠机构处聚拢。本发明采用聚拢式折叠方式,折叠后可以在长度方向和宽度方向上同时进行折叠,折叠方法简单,使用方便,折叠后体积小,无锐角结构,不会存在安全隐患。本发明的连接杆采用三段式弯折设计,并在中心支撑机构处形成拱形结构,具有良好的承载力和系统稳定性。由于装置整体稳定性和承载力好,因此可以取消在长度方向上的折叠机构设置,减轻车架整体的重量,便于携带。
