Abstract

The invention discloses a gear drive type ratchet wheel lifting mechanism which comprises a ratchet wheel wrench component, a screw shaft, a sleeve and a brake. The ratchet wheel wrench component and the brake are arranged on the sleeve. The screw shaft is driven to do lifting motion and is arranged in the sleeve and matched with the sleeve. The brake brakes the ratchet wheel wrench component. Lifting adjustment is carried out on the screw shaft through the ratchet wheel wrench component. The top end of the screw shaft is used for bearing weights. The gear drive type ratchet wheel lifting mechanism is composed of the ratchet wheel wrench component, the screw shaft, the sleeve and the brake; the brake is used for braking a ratchet; it is guaranteed that the ratchet is kept static when a check block moves along the ratchet; the ratchet wheel wrench component is in a gear drive type, transmission tends to be non-polar and is smooth and high in reliability; when a ratchet wheel wrench is operated to swing, the ratchet wheel wrench is more stable and saves more labor. The lifting mechanism is high in reliability, and no slipping phenomenon happens. When the lifting mechanism is operated manually, more time and labor are saved.

Description

technical field [0001] The invention relates to a lifting mechanism, in particular to a gear transmission ratchet lifting mechanism. Background technique [0002] The lifting mechanism of previous jacks or other similar products all adopts ratchet transmission. Due to the large distance between two adjacent teeth of the ratchet, it is relatively laborious to operate in practice, and the transmission reliability is poor and easy to be damaged. [0003] Therefore, it is necessary to provide a new technical solution to solve the above problems. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a gear-driven ratchet lifting mechanism. It saves time and effort when manually operating the lifting mechanism, and improves the reliability of the lifting mechanism. [0005] For solving the technical problem of the present invention, the technical scheme that the present invention adopts is: [0006] A gear-driven ratchet...
