Two-leg pneumatic tooth-row lifting table

Abstract

The invention discloses a two-leg pneumatic tooth-row lifting table, which comprises tabletop supporting pieces which are symmetrically arranged at the left and right sides and a horizontal supportingpiece which is connected between the two tabletop supporting pieces, wherein upper vertical pillars are fixedly connected to the lower ends of the tabletop supporting pieces, and the lower end of each upper vertical pillars movably sleeves in a lower vertical pillar; a tooth-row is fixedly arranged in each upper vertical pillar in a longitudinal direction; synchronous teeth are fixedly arranged on the inner side faces of the lower vertical pillars; the synchronous teeth are correspondingly meshed on the tooth-rows at the same sides; a synchronous shaft is fixedly arranged between axes of thetwo synchronous teeth; controllable gas springs are each arranged in the upper and lower vertical pillars at each side; a pull handle switch is arranged on the horizontal supporting piece, and pull rods are arranged on the tabletop supporting pieces; and a left pull wire and a right pull wire are connected to the pull handle switch. The two-leg pneumatic tooth-row lifting table is concise in structure and convenient to operate; moreover, the left side and the right side of the lifting table can get completely asynchronous; and the tabletop, when applied by pressure from external side, is prevented from sinking down under a circumstance of being kept immobile.

Description

technical field [0001] The invention belongs to the technical field of furniture, and in particular relates to a double-leg pneumatic tooth lifting table. Background technique [0002] Desk is a kind of essential article in people's life, and existing table mainly is to fix table leg under the tabletop board, and the height of tabletop board cannot be adjusted up and down, can't meet the demand of different heights, and it is relatively inconvenient to use. In order to meet people's needs for different heights of the table, there have been lift tables with adjustable table heights. However, the lift tables currently on the market not only have complex structures, but also the left and right legs are not synchronized when rising or falling, and the rise and fall are not smooth. At the same time, when the table is fixed, when the table is subjected to a force of 1000N, the table will sink, causing inconvenience to use. Contents of the invention [0003] In order to overcome...
