The invention discloses a building cart convenient for saving effort in the process of going uphill/downhill, and belongs to the technical field of constructional engineering. The building cart comprises a cart body, two cart handles are transversely welded at one end of the cart body, a driving shaft is arranged between two hinge plates in an inserted mode, two ends of the driving shaft extend tothe outer sides of the hinge plates and are rotatably connected with walking wheels, a first one-way bearing is arranged on the middle of the driving shaft between the two hinge plates in a sleevingmode, a gear disc is welded on an outer ring of the first one-way bearing, an L-shaped extrusion cylinder is welded at the bottom of a connecting plate, a guiding pipe is connected with the top of oneside of the L-shaped extrusion cylinder, two connecting rods extend to the inner sides of the ends of the cart handles and are welded with limiting blocks, and an extrusion cylinder is transversely welded at the bottom of one connecting rod. The cart can conveniently walk uphill, the labor intensity of workers is reduced, the cart body is more effort-saving in the process of going uphill, and thecart can be conveniently decelerated in the process of going downhill.

本发明公开了一种便于上下坡省力的建筑推车，属于建筑工程技术领域，包括推车本体，所述推车本体的一端横向焊接有两根推车把手，两个所述铰接板之间穿插有驱动轴，所述驱动轴的两端皆延伸至铰接板的外侧并转动连接有行走轮，两个所述铰接板之间的驱动轴中间位置处套设有第一单项轴承，且第一单项轴承的外圈上焊接有齿轮盘，所述连接板的底部焊接有L型挤压筒，所述L型挤压筒一侧的顶部连接有导向管，两根所述连接杆延伸至推车把手端部的内侧并焊接有限位块，其中一根所述连接杆的底部横向焊接有挤压筒。本发明方便辅助推车进行上坡行走，降低劳动者的强度，使得推车本体在上坡时更加省力，下坡时便于对推车进行减速。
