Small-sized portable domestic lifting device

Abstract

The invention discloses a small-sized portable domestic lifting device comprising a lifting mechanism, a top supporting mechanism and a lower supporting mechanism. The top supporting mechanism is arranged on the top of a stand column. The lower supporting mechanism is arranged on the lower portion of the stand column. The top supporting mechanism is arranged on a supporting plate. The top supporting mechanism comprises multiple supporting assemblies which are distributed evenly and circumferentially in a vertical plane. Each supporting assembly comprises a fixed arm on the inner side and a swing arm, wherein the outer length is adjustable. Each fixed arm is vertically installed on the supporting plate. The lower end of each swing arm is connected to the supporting plate in a hinged manner. Each swing arm and the corresponding fixed arm are connected through a connecting rod hinged to the swing arm and the fixed arm, and the length of the connecting rod is adjustable. The swing range of each swing arm is between the vertical position and the horizontal position. The lower supporting mechanism is arranged on a supporting sleeve and comprises multiple supporting arms which are evenly and circumferentially distributed in a horizontal plane in the radial direction, and the length of each supporting arm is adjustable. The supporting arms are installed on the supporting sleeve. The lifting mechanism is supported by the top supporting mechanism and the lower supporting mechanism, and therefore the whole lifting device is more stable.

Description

technical field [0001] The invention relates to a hoisting appliance, in particular to a small portable household hoisting device. Background technique [0002] Lifting devices are very common in our daily life, through which objects can be transported to high places. [0003] With the improvement of people's living standards, people have also put forward higher requirements for lifting devices. Residents living on high floors need lifting devices with a more stable structure to transport heavy objects. [0004] However, most of the lifting devices at the present stage do not use support structures. When lifting heavy objects, it is difficult to avoid the shaking of the device when lifting only by its own weight and counterweight, which increases the danger of the lifting process. For example, the application number is 201410518127.2 The invention patent application for "Lifting Mechanism" is a typical representative of this kind of lifting device. Contents of the inventi...
