Multi-gear boosted lifting cabinet

Abstract

The invention discloses a multi-gear boosted lifting cabinet. The multi-gear boosted lifting cabinet comprises a material storage frame, a pulling basket, a first rotating rod, a second rotating rod and a lifting controller. The lifting controller comprises a gear, a rack matching with the gear, a cylinder, a rotating shaft and a first boosting mechanism; the upper end of the cylinder is fixed atthe side plate of the shell of the controller while the lower end thereof is fixedly connected to the rack by a cylinder expansion link; the first boosting mechanism is connected with the gear; and the cylinder expansion link is provided with a locking ring at the position close to the end part and a locking part matching with the locking ring for locking is arranged in the cylinder. According tothe multi-gear boosted lifting cabinet, the lifting controller composed of the gear, the rack and the cylinder has higher stability; the pulling basket can be fixed efficiently when the pulling basketfalls to the limit as the locking ring is arranged at the cylinder expansion link, and hands can be released to place materials in the pulling basket or take out materials from the pulling basket; inaddition, due to clutching arrangement of a spring and a clockwork as well as a first button and a second button, multi-gear boosting can be realized and a bearing range of the pulling basket is enlarged.

Description

technical field [0001] The invention relates to the technical field of lockers, in particular to a multi-gear afterburner lifting locker. Background technique [0002] Cabinet storage shelves are used to store utensils and are an important part of everyday life. In order to meet people's daily needs, there have been storage racks with energy storage and buffering functions, which can make the storage rack rise and fall smoothly. Existing multi-gear afterburner lifting locker adopts rotating disk, buffer, spring to cooperate mutually, plays the effect of buffering when locker lifts. However, it has been found in practical applications that the existing lifting lockers have the following disadvantages: 1. The stability of the ordinary rotating disk lifting process is not high, and it is easy to be damaged or malfunction during long-term use; 2. The buffer is a plunger type. It deflates when it falls, and inflates when it rises, which only acts as a buffer; and when the sprin...

However, it has been found in practical applications that the existing lifting lockers have the following disadvantages: 1. The stability of the ordinary rotating disk lifting process is not high, and it is easy to be damaged or malfunction during long-term use; 2. The buffer is a plunger type. It deflates when it falls, and inflates when it rises, which only acts as a buffer; and when the spring is hooked by the button, and the item is placed or taken down, since the buffer cannot be locked, the basket must be held by hand, otherwise it will pull The basket will rebound, and you cannot release your hands to pick up items; 3. There are at most three levels of afterburner, and the load range that the storage rack can carry is small
