Simple weight lifting device

Abstract

The invention discloses a simple weight lifting device. The simple weight lifting device comprises a support column, and a swing mechanism capable of swinging along the support column; the swing mechanism comprises a lifting block, an upper lifting plate, a lower lifting plate and a swing block; the lifting block sleeves the support column; one end of the swing block is hinged with the lifting block, and the other end is an external force driving end; the upper lifting plate sleeves the support column, and is arranged on the outer side of the upper part of the lifting block; one end of the upper lifting plate butts against the lifting block, and a spring is arranged between the other end and the lifting block; the lower lifting plate sleeves the support column, and is arranged in the swingblock; the upper part of the lifting block and the lower lifting plate are connected through a tension spring; and the swing block is provided with a stop part for stopping the end part of the lowerlifting plate. The simple weight lifting device is purely mechanical, simple in structure and low in production cost, can lift weights through manual operation, and is wide in applicability and simplein adjustment.

Description

technical field [0001] The invention relates to a device for lifting heavy objects, in particular to a device for lifting heavy objects mechanically.
