The invention relates to the related field of elevators, and discloses an elevator capable of changing the conveying speed according to the weight. The elevator comprises a main body box, a lifting block cavity with an upward opening is formed in the main body box, a transmission bevel gear cavity is formed in the lower side of the lifting block cavity, and nut block cavities which are bilaterally symmetrical about the center of the transmission bevel gear cavity communicate with the lower side of the lifting block cavity; and the weight of an object carried by the elevator is judged through the downward moving distance of an object placing block, when the weight is lighter, the ascending speed of the elevator is increased, and therefore the conveying time of the elevator is shortened, the working efficiency of the elevator is improved, and when the weight is heavier, in order to stabilize the object, the ascending speed of the elevator is decreased, and the safety of the elevator is improved. The elevator can descend rapidly, the working efficiency of the elevator is further improved on the premise that certain safety is guaranteed, on the other hand, the lifting block can completely retract into the main box body, and meanwhile, the risk that objects fall off can be avoided through popup of a baffle, the appearance is conventional, and carrying is convenient.

    本发明涉及升降机相关领域,公开了一种根据重量大小改变运送速度的升降机,包括主体箱,主箱体内设有开口向上的升降块腔,升降块腔下侧设有传动斜齿轮腔,升降块腔下侧连通设有以传动斜齿轮腔位中心左右对称设置的螺母块腔,通过置物块下移的距离来判断升降机所载物体的重量大小,当重量较轻时,升降机上升速度就加快,从而降低升降机运送的时间,提高升降机工作的效率,当重量较重时,为了物体的稳定,升降机上升速度会降低,加大升降机的安全性,升降机可快速下降,在保证一定的安全性的前提下进一步提高升降机的工作效率,另一方面,升降块可完全缩回主箱体内,同时可通过挡板的弹出来阻挡物体掉落的风险,在外观上也较为常规,便于搬运。
