Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of storage device, specifically relates to a doll type lifting mechanism. BACKGROUND

[0002] The floor cabinet is an important tool for people to store articles, but the floor cabinet occupies a larger ground space, which seriously affects people's life. Therefore, the hanging cabinet gradually attracts people's favor, and the hanging cabinet can fully utilize the limited space and store more articles. However, in actual use, due to the different heights of different people, it is inconvenient to take articles.

[0003] In view of the above problems, the lifting hanging cabinet emerges as the times require. At present, the lifting hanging cabinet can move the articles in the storage assembly out of the cabinet body downward to facilitate people to take articles, and after the articles are taken, the lifting hanging cabinet lifts the storage assembly into the cabinet body to save space. The lifting machine is one of the important storage mechanisms of the lifting hanging cabinet, and the structure determines the occupation of the storage space. For example, patent No. 202122523325.6 discloses a lifting hanging cabinet, the lifting mechanism of the lifting hanging cabinet includes a driving assembly and a storage assembly. The driving assembly can drive the storage assembly to move out of or into the through cavity. The lifting hanging cabinet can be conveniently taken by people of different heights, and does not occupy the ground space, and the practicability is improved.

[0004] However, the lifting mechanism has the following problems: 1. It is a single-section lifting mechanism, and the lifting length of the lifting mechanism and the storage depth of the cabinet body are matched with the specified size. That is, when the length of the lifting is longer, the volume of the cabinet body also increases, and the space occupied is large; 2. The driving assembly is composed of a driving part, a pulley set and a lifting rope. The driving assembly adopts the linkage mode of the pulley set and the lifting rope. The linkage mode has the problems of slow lifting speed and poor running stability. In addition, due to the use of the lifting rope, the load weight is limited, and the lifting rope is easy to deviate, which affects the subsequent lifting stability. UTILITY MODEL CONTENTS
