Problems solved by technology

To increase the height adjustment range of the lifting table, it is necessary to choose a gas spring with a large extendable range, which increases the risk of gas spring failure. Moreover, the switch valve of the gas spring controlled by the wire rope handle is not stable, and the wire rope itself Intrinsic travel can affect the effective travel of the lifting mechanism

Abstract

The invention relates to the technical field of furniture, and provides a multi-stage lifting device. The device comprises an upper fixed plate, a gas spring switch assembly, at least three stages oftelescopic shells and at least two gas springs. The top of the uppermost telescopic shell is connected to a lower bottom surface of the upper fixed plate; all the gas springs are arranged in the telescopic shells; every two gas springs are connected through a gas spring connecting piece, one end of the gas spring connecting piece is arranged at the top of one gas spring in a sleeving mode, the other end of the gas spring connecting piece is arranged at the bottom of the other gas spring in a sleeving mode, the gas spring switch assembly is installed on the lower bottom surface of the upper fixed plate, and switch valves at the top ends of all the gas springs are opened through the gas spring switch assembly. The multiple gas springs are connected end to end through the gas spring connecting piece, the multiple gas springs with a small extension range can be connected to achieve lift control over three stages or above, gas springs with a large extension range are prevented from being used, and the risk of faults is reduced.

Description

technical field [0001] The invention relates to the technical field of furniture, more specifically to a multi-level lifting device and a lifting table. Background technique [0002] At present, most of the height-adjustable manual lifting tables on the market use gas springs as the source of lifting power, and all use traditional wire rope handles for control. In this way, the height control of the lifting table is at most two levels. To increase the height adjustment range of the lifting table, it is necessary to choose a gas spring with a large extendable range, which increases the risk of gas spring failure. Moreover, the switch valve of the gas spring controlled by the wire rope handle is not stable, and the wire rope itself Intrinsic travel affects the effective travel of the lift mechanism. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multi-stage lifting device, which can use a gas spring with a smal...
