Counterweight manual desktop lifting device and counterweight manual desktop lifting method adaptive to sitting and standing alternation

Abstract

The invention discloses a counterweight manual desktop lifting device and a counterweight manual desktop lifting method adaptive to sitting and standing alternation. The counterweight manual desktop lifting device and the counterweight manual desktop lifting method are used for solving problems of complicated structures, high energy consumption and maintenance cost and expensiveness or problems of low lifting speeds and time and labor wastage of existing desktop lifting devices. The counterweight manual desktop lifting device comprises a desktop, a counterweight, a drive and a support. The desktop refers to an object required to be lifted, the counterweight refers to an article which is configured to keep balance with the desktop, the drive refers to a portion which is connected with the desktop and the counterweight and is used for transmitting acting force of a user, and the support refers to a structure which supports the desktop, the counterweight and the drive. The counterweight manual desktop lifting device and the counterweight manual desktop lifting method have the advantages that balance states are established between the desktop and the counterweight by the aid of equal or equivalent weight via the drive, so that the desktop can remain at a certain altitude without actions of external force; the user can easily lift the desktop to an appropriate altitude within a few seconds by means of slightly exerting hand power when using the counterweight manual desktop lifting device; the lifting speeds can be obviously increased by the aid of the counterweight manual desktop lifting device, the health level and the work and learning efficiency of sedentary populations such as students, white-collar workers and customers of internet cafes can be improved, expenditures can be reduced relatively, and environments can be beautified relatively.

Description

technical field [0001] The invention relates to a manual desktop lifting device suitable for people who alternate between sitting and standing, in particular to a solution to the power required for instant lifting. Background technique [0002] In the current desktop lifting device, when the desktop (including its upper and lower attachments, the same below) needs to be raised or lowered, an electric or manual lifting method is adopted. Although the electric way is labor-saving, the structure is complex, consumes energy, and the maintenance cost is high. The important problem is that the currently widely sold and used electric lifting device does not take into account the needs of people to sit and stand alternately in design. For example, the "LCD screen electric lifter" that is widely used in high-end video conference rooms and audio-visual classrooms, the lifting height is only based on the user's sitting position. Although some recent electric desktop lifting devices h...

Problems solved by technology

But the existing manual method also has disadvantages: the existing shaking method (such as "a kind of computer lifting device suitable for sitting and standing alternately office" whose patent authorization announcement number is "CN203058813U") is mainly by shaking devices such as ratchet wheels, The desktop is driven up and down by wire ropes or chains, racks, and screw rods. Its main disadvantage is that it is limited by the shaking speed, and the lifting speed is relatively slow. Especially when the objects that need to be lifted are heavy, it is difficult or even impossible to complete; the existing moving methods (such as "a computer lifting device placed on the desktop" whose patent authorization announcement number is "CN202286969U"), mainly directly move the desktop by hand, and the weight of the desktop and the attachments on it is all borne by hand, which leads to the need to When the lifting object is heavy, it is difficult or even impossible to complete; the existing gear shifting method is mainly designed for growing children. Every time when shifting gears, it is necessary to disassemble the lifting device with the help of certain tools. The reserved screw or pin hole is used for height adjustment, so it is time-consuming and laborious, and cannot be lifted immediately
