Watertight device for directly pushing, clamping and pressing waterproof gate plate

The utility model provides a watertight device for directly pushing, clamping and pressing a waterproof gate plate. The two ends of the pivot rod slide along the inclined groove holes in a displacement mode. A shaft pin at the front end of the push rod arm is guided by the horizontal slotted hole; the front end of the push rod arm pushes the clamping and pressing acting surface of the clamping andpressing rod to generate double actions of direct pushing, clamping and locking on the surface of one end of the waterproof door plate, so that the surface of the other end of the waterproof door plate can form a water-tight pressing and attaching waterproof effect which is separated from a limited side of the rail in the door rail; according to the overall structure, the clamping and pressing rod is controlled to generate clamping and pressing or leaving actions on the waterproof door plate by acting on the telescopic end of the telescopic actuator, and the beneficial effects that the transmission structure is simpl
