Abstract

The invention discloses a vertical lifting device achieving multi-gear force adjustment. The vertical lifting device comprises a basket arranged in a cupboard, a left lifting device and a right lifting device are arranged in the cupboard, each lifting device comprises a guide rail perpendicular to the horizontal plane, and the basket is installed on the lifting devices through sliding blocks; the vertical lifting device further comprises a push-and-pull handle, a left push-and-pull arm and a right push-and-pull arm are arranged on the two sides of the push-and-pull handle, and each push-and-pull arm is connected with a first rotating point at the bottom of the corresponding lifting device; each push-and-pull arm is provided with a sliding hole, the left side and the right side of the basket are each provided with a sliding shaft, and the sliding shafts are embedded into the sliding holes in a left-and-right corresponding mode. According to the vertical lifting device achieving multi-gear force adjustment, the design is reasonable, unpowered mechanical vertical lifting is adopted, multiple bearing strength gear adjustment is provided, use is convenient, and the using space is effectively saved.

Description

technical field [0001] The invention relates to the field of cabinets, in particular to a multi-gear vertical lifting device for force adjustment. Background technique [0002] In the kitchen, since there is space above cooking equipment such as integral cabinets, wall cabinets are generally installed.

[0003] There are also some lift-type cabinets ...

AI Technical Summary

Problems solved by technology

[0003] There are also some lift-type cabinets in the traditional technology, which use motors to drive steel ropes for lifting. This electric lift cabinet cannot be used when the power is off, and the steel rope will be deformed due to long-term use, which increases the instability of the use of the cabinet.

There are also some cabinets driven by racks. This kind of cabinets are too rigid and are used by humans. If there is a fault or people do not pay attention, it will cause hand pinching or other unsafe factors.

There are also some purely mechanical manual lifting cabinets in the prior art, which use parallel bars to swing to make the basket tilt down. This kind of basket is a waste of space except that it is not stable enough, and it needs to be reserved in front of the cabinet. There is space for lowering the basket, which is not convenient and practical
