Variable load adjustable lift object storage cabinet

A variable load adjustable lifting storage cabinet comprises a storage cabinet, a storage frame, right-left parallel connecting bars and right-left lifting controller, arranged on the main shaft in the shell of the right-left lifting controller fixedly connected with the active connecting rod. The terminal close to the active connecting rod is fixedly connected with the connecting kinetosome. The terminals are respectively combined with the energy accumulator of the stressed plate of the shell and the other terminals of the damping buffer which are respectively combined with the pin shaft in the connecting kinetosome entering into the shell. The energy accumulator is combined with the terminal of the stressed plate of the shell and is connected with the basic spring by the traction rope which has a stop block. The upper terminal of the stop block in which the traction rope is positioned is provided with a telescopic bolt. The rigidity of the energy accumulator is bigger than the rigidity of the basic spring. With compact structure, easy manufacture, low cost, convenient operation, the utility model can adapt to variation of the larger bearing weight, makes the balance adjustment with the range of the change of the bearing weight which greatly improves the balance effect of the gravity torque and the reaction torque of the lifting device with the stable drop and the free return of the storage frame without any impact.
