The invention belongs to the technical field of jacks and particularly relates to a universal rotating hinge type jack based on gear transmission. The universal rotating hinge type jack based on geartransmission comprises a supporting mechanism and a driving mechanism, wherein the driving mechanism is installed on the supporting mechanism. The jack has the function that the jack is driven at anyangle to move upwards so as to support loads, and meanwhile a telescopic rod can determine that a fourth gear is engaged with one of a first gear ring, a second gear ring, a third gear ring and a fourth gear ring. When the fourth gear is engaged with the first gear ring to drive the supporting mechanism to work, a user can jack up the loads on the jack in a labor-saving mode. When the fourth gearis engaged with the second gear ring, the third gear ring and the fourth gear ring in sequence, the user spends more and more force in driving the loads on the jack to move in sequence.
Description
technical field [0001] The invention belongs to the technical field of jacks, and in particular relates to a universal rotating articulated jack based on gear transmission. Background technique [0002] Existing jack adopts plunger, hydraulic cylinder, four-deformation structure more as the jack of rigid top lifting part at present. It has the characteristics of compact structure, stable operation, large supporting force, and self-locking. The structure of the articulated jack is compact and the use space is small, but the pressure rod of the articulated jack cannot be rotated, and the traditional articulated jack is not very convenient to use, so it is necessary to design a universally rotating articulated jack based on gear transmission. [0003] The present invention designs a universal rotating articulated jack based on gear transmission to solve the above problems. Contents of the invention [0004] In order to solve the above-mentioned defects in the prior art, the...
