The invention relates to a loading and unloading cart which comprises a supporting frame, a base, a bearing frame, elastic pieces and idler wheels, wherein the supporting frame is arranged on one sideof the base, the idler wheel is rotatably arranged on one side of the base back to the supporting frame, the supporting frame is provided with a guide structure, the guide structure extends along thedirection from the supporting frame to the base, and the bearing frame is slidably arranged on the guide structure; one end of the elastic piece is connected with the bearing frame, and the other endof the elastic piece is connected with the supporting frame or the base. When the number of layers of the stacked articles is continuously reduced, the bearing frame can still be lifted through the elastic piece, so that the bearing frame is kept at a uniform height, and a user can conveniently and continuously unload the articles; when the number of layers of stacked articles is continuously increased, the bearing frame bears load and descends in the direction close to the base, the elastic piece can provide force for the bearing frame in the direction away from the base at the moment, excessive descending of the bearing frame is avoided, the bearing frame can be kept at the uniform height, and a user can continuously load the articles conveniently.
本发明涉及一种装卸载推车,包括支撑架、底座、承载架、弹性件和滚轮;支撑架设置于底座的其中一面,滚轮转动设置于底座背向支撑架的一面,支撑架设置有导向结构,导向结构沿支撑架到底座的方向延伸设置,承载架滑动设置于导向结构;弹性件的一端与承载架连接,弹性件的另一端与支撑架或底座连接。当层叠的物品的层数不断减少时,依然能够通过弹性件升起承载架从而使得承载架维持在均匀的高度,便于用户连续地卸货;当层叠的物品的层数不断增加时,承载架负重并朝靠近底座的方向下降,此时弹性件能够给承载架提供远离底座方向的力,避免承载架过度下降,这样也能够使得承载架维持在均匀的高度,便于用户连续地装货。
