The protection type trundle support comprises a wheel fork, the wheel fork is of a four-part structure formed by bending four edges of an integrally-formed metal plate, the four edges of the integrally-formed metal plate form an upper top face, a left fork body, a right fork body, a front protection baffle and a rear protection baffle, and the bent portions of the upper top face, the left fork body and the right fork body are additionally-formed metal plates; the upper top surface is provided with a vertical axial through hole, a roller mounting space is formed between the left fork body and the right fork body, the lower parts of the left fork body and the right fork body are provided with a pair of transverse through holes, the two side surfaces of the left fork body and the right fork body are respectively provided with a bent edge, and the bent edges are not only integrally formed with the left fork body and the right fork body, but also extend towards the direction of the roller mounting space. The wheel fork is an approximately U-shaped part formed by bending the four edges of the steel plate with the thickness of 2.5 mm, and the U-shaped part is high in structural strength, not prone to deformation and damage and good in safety.
本发明公开了一种防护式的脚轮支架,包括轮叉,所述轮叉由一体成型的金属板四边折弯形成上顶面,左叉体、右叉体、前护档以及后护档四部分结构,且上顶面与左叉体和右叉体折弯部位均为增加压型金属板,所述上顶面上设有一竖直轴向穿孔,所述左叉体和右叉体之间为滚轮安装空间,且左叉体和右叉体下部设有一对横向对穿孔,左叉体和右叉体两侧面均设有弯边,所述弯边不仅与左叉体和右叉体一体成型,而且朝向滚轮安装空间方向延伸。本发明轮叉是用2.5mm厚的钢板四边折弯形成的一种近似U形的件,这种U形件结构强度高,不易变形损坏,安全性好。
