Abstract
The invention discloses a connecting rod type hydraulic clamping device in the technical field of mechanical locking devices. The connecting rod type hydraulic clamping device comprises a telescopic cylinder, a fixed mounting seat, a transmission chain and a movable lock plate. When the connecting rod type hydraulic clamping device is in the locking state, a sliding block pulls the movable lock plate so as to enable a second guiding surface to abut against the periphery of a second guiding column, and the movable lock plate rotates under the action of an abutting force of the second guiding column, so that a hook and a target are locked and abutted; and when the connecting rod type hydraulic clamping device is in the unlocking state, the sliding block drives the movable lock plate so as to enable a first guiding surface to abut against the periphery of a first guiding column, and the movable lock plate rotates under the action of an abutting force of the first guiding column, so that the hook is separated from the target. The sliding block in the transmission chain drives the movable lock plate to move, a guiding mechanism formed by the first guiding column and the second guiding column is used for guiding the movement locus of the movable lock plate through abutting, so that the locking and unlocking process of the movable lock plate can be well controlled.
