Abstract

The invention relates to a low-friction labor-saving drain valve lifting mechanism and a drain valve thereof. The lifting mechanism is arranged in a drain valve body; a button base is installed on thedrain valve body; and a buoy assembly which is in linkage fit with the lifting mechanism to drain and close water is arranged in the drain valve body. The lifting mechanism comprises a button, a driving piece, two supporting swing arms, a pull rod and a lifting rod. The driving piece is mounted at the lower side of the button, and two pressing rods are downwards formed on the driving piece; the two supporting swing arms are hinged to the same transverse shaft of the button base to form an X-shaped supporting structure; the upper end of each supporting swing arm is connected with a pressing rod of the driving piece in a supporting mode; and the lower ends of the supporting swing arms are hinged to pull rods arranged on the two sides of the lifting rod; and the two pressing rods of the driving piece drive the two supporting swing arms to swing in the opposite directions at the same time so as to drive the pull rods on the two sides to pull the lifting rods at the same time to form a vertical lifting balance structure of the lifting mechanism. The low-friction labor-saving drain valve lifting mechanism has the advantages that the friction is low, the labor is saved, and the service life of the product is prolonged.

Description

technical field [0001] The invention relates to a low-friction and labor-saving drainage valve lifting mechanism and the drainage valve thereof. Background technique [0002] The structure of the existing drain valve is provided with a button, a button seat, a lever assembly, a lifting rod, a water sealing sheet, a floating barrel and a support, wherein the button seat is installed on the drain valve body, and the lever assembly, the lifting rod, the floating barrel and the support Assembled in the drain valve body. When flushing, press the button to make the lever assembly act, and the lever assembly drives the lifting rod to lift upwards, and the water sealing sheet is lifted to realize flushing. [0003] The lifting rod that lifts up or drops the water sealing sheet to the drain is fixed by the barrel support tube in the drain valve. The tube support structure is generally provided with a groove for the tube support on the barrel support, and a groove along the pull rod ...
