A mechanical three-leg automatic lifting table and its adjustment method

Abstract

The invention discloses a mechanical three-legged automatic elevating desk and an adjusting method for the same. The elevating desk comprises a desktop plate, a desk case and three desk legs, wherein each desk leg is formed by a fixed leg and a liftable elevating leg fixed in the fixed leg; the desk case and / or the desktop plate is fixed on the top ends of the elevating legs; the top of each elevating leg is provided with a rope winding wheel fixed in the desk case; the bottom of each elevating leg is provided with a movable pulley fixed in each elevating leg; a rope, one end of which winds the rope winding wheel and the other end of which winds the movable pulley and then is fixed on the rope arranged on the top of the fixed leg is disposed in the same elevating leg; the desk case contains a first transmission shaft and a second transmission shaft; the external end of the first transmission shaft is provided with a rope winding wheel; the external end and the internal end of the second transmission shaft are both provided with a rope winding wheel; the inner end of the first transmission shaft is engaged with the inner end of the second transmission shaft via a bevel gear mechanism; the desk case is provided with a driving mechanism driving the first transmission shaft and / or the transmission shaft to rotate. The mechanical three-legged automatic elevating desk is advantaged by stable elevation, great synchronism and great desktop space, thereby being quite suitable for business office.

Description

technical field [0001] The invention relates to a mechanical three-leg automatic lifting table and an adjusting method thereof. Background technique [0002] With the improvement of socio-economic living standards, people have higher and higher requirements for the convenience and comfort of tables. The table with high cost performance, stable transmission and automatic height adjustment is popular with consumers. [0003] The types of automatic lifting tables in the existing market are mainly mechanical and electric, and most of them are two-leg lifting tables. The cost of the electric adjustable table is high, and it is inconvenient to move because of the need for a fixed power supply, which is very inconvenient for the user. [0004] The transmission of the mechanical lifting table is stable, but there are few types at present, and the table parts are many and difficult to assemble, and some of them are too heavy. Ordinary lifting tables are based on the shape of ordin...

Problems solved by technology

The cost of the electric adjustable table is high, and it needs a fixed power supply, which is inconvenient to move, which is very inconvenient for the user

[0004] The transmission of the mechanical lifting table is stable, but there are few types at present, and there are many table parts, which are difficult to assemble, and some of them are too heavy.

Ordinary lifting tables are based on the shape of ordinary classroom desks, plus some simple telescopic lifting structures. There is a small space on the desktop, the lifting is not stable enough, the operation is difficult when lifting, the labor intensity is high during the adjustment process, and the adjustment accuracy is poor. , complex process, lack of corresponding defects such as automation and mechanization, not suitable for business office use
