The trolley comprises a chassis, a pair of push rods are fixedly connected to one end of the chassis, a buffer groove is formed in the other end of the chassis, an anti-collision rod is arranged in the buffer groove in a sleeved mode and connected with the buffer groove through a buffer spring, a damping groove is formed in the bottom of the chassis, and a bottom rod is arranged in the damping groove in a sleeved mode and connected with the damping groove through a damping spring. Wheels are rotatably connected to the two ends of the bottom rod, a damping plate set is connected to the top of the bottom rod, a cargo box is fixedly connected to the top of the chassis, an inner groove is formed in the bottom of the cargo box, and an inner box is slidably connected into the inner groove. And bottom-layer goods can be prevented from being extruded and damaged due to the fact that the upper layer is too heavy, and therefore bolts in the goods box are protected, and losses of users are reduced.

    本发明涉及一种螺栓加工用手推车,包括底盘,底盘一端固定连接有一对推杆,另一端开设有缓冲槽,缓冲槽内套设有防撞杆,防撞杆通过缓冲弹簧与缓冲槽连接,底盘底部开设有减震槽,减震槽内套设有底杆,底杆通过减震弹簧与减震槽连接,底杆两端均转动连接有车轮,且顶部连接有减震板组,底盘顶部固定连接有货物箱,货物箱底部开设有内槽,内槽中滑动连接有内箱,本装置有效的对颠簸移动过程中的手推车进行减震,并且可以对车体发生碰撞时进行缓冲,还可以避免底层货物因上层过重而相互挤压,发生破损,从而保护货物箱内的螺栓,降低使用者损失。
