Lever servo unit with changeable elevation angle

A technology of power-assisted mechanism and elevation angle, which is applied in the direction of hoisting device and lifting frame, etc., which can solve the problems that the lift cannot be changed at will, the distance between the platform and the chassis is large, and the hydraulic cylinder cannot be placed completely horizontally, so as to achieve a small distance and an increased elevation angle. Larger, faster lifting effects

Problems solved by technology

The disadvantage is that before the lift works, when the bracket is folded and placed, in order to achieve lifting, the hydraulic cylinder cannot be placed completely horizontally, and it needs to be at a certain angle to the horizontal plane, so the distance between the platform and the chassis is relatively large. To make the car easy to drive on the platform, it is usually necessary to dig a certain depth under the chassis, so the position of the car lift cannot be changed arbitrarily during use

Abstract

The invention discloses a lifter of vehicle, especially providing an elevation-variable lever device, which comprises a bottom support, a platform, brackets, a piston rod and a hydraulic cylinder. Wherein, the brackets are connected between the bottom support and the platform; the brackets are hinged to each other; the piston rod is matched with hydraulic cylinder, whose two ends are connected to the bracket, while at least one connection is hinged by connecting blocks. The invention has the advantages that: the platform has small distance from bottom support, without digging out sand; the position of lifter can be freely changed; the elevation is increased caused by hinged connecting block, to improve the lifting speed.

Description

technical field [0001] The invention relates to car lifts, in particular to a variable elevation angle lever power-assisted mechanism. Background technique [0002] The car lift disclosed in the prior art includes an underframe and a platform, and a bracket is connected between the underframe and the platform, and the brackets are hinged to each other, and the piston rod and the hydraulic cylinder are associated with the bracket. The disadvantage is that before the lift works, when the bracket is folded and placed, in order to achieve lifting, the hydraulic cylinder cannot be placed completely horizontally, and it needs to be at a certain angle to the horizontal plane, so the distance between the platform and the chassis is relatively large. To enable the car to easily drive onto the platform, it is usually necessary to dig a certain depth under the chassis, so the position of the car lift cannot be changed arbitrarily during use. Contents of the invention [0003] The ob...
