Low-friction labor-saving double-drainage-valve lifting mechanism and drainage valve thereof

Abstract

The invention relates to a low-friction labor-saving double-drainage-valve lifting mechanism and a drainage valve thereof. A buoy assembly which is in linkage fit with the lifting mechanism to drain and close water is arranged in a drainage valve body; the lifting mechanism comprises a left swing piece, a right swing piece and a lifting rod. Swing pieces of the left swing piece and the right swing piece are erected on the left carrying rod and the right carrying rod of the button base respectively to form a pivot joint rotating structure. A front supporting shoulder and a rear supporting shoulder are arranged on the upper portion of the lifting rod, sliding grooves are formed in the front supporting shoulder and the rear supporting shoulder, a left swing piece hinge shaft is installed on the right half sections of the sliding grooves to form a hinge rotation labor-saving structure, and a right swing piece hinge shaft is installed on the left half sections of the sliding grooves to form a hinge rotation labor-saving structure. When water is closed, the swing pieces of the left swing piece and the right swing piece are reset, and the left swing piece, the right swing piece and the lifting rod roughly form a Y-shaped structure. During drainage, the swing pieces of the left swing piece and the right swing piece swing downwards, so that the left swing piece, the right swing piece and the lifting rod are approximately of an umbrella-shaped structure to form a left-right balance vertical lifting structure of the lifting mechanism. The device has the advantages of low friction, labor saving and prolonged service life of products.

Description

technical field [0001] The invention relates to a low-friction and labor-saving double-drain valve pulling mechanism and a drain 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 bucket and a bracket, wherein the button seat is installed on the drain valve body, and the lever assembly, the lifting rod, the floating bucket and the bracket are provided. Assembled in the drain valve body. When flushing, press the button to make the lever assembly move, and the lever assembly drives the lifting rod to lift up, and the water sealing sheet is lifted to realize flushing. [0003] The lifting rod that lifts or drops the water-sealing sheet to the drain is straightened through the barrel bracket in the drain valve. The tube is generally a groove with a straight pipe on the barrel bracket, and a groove along the barrel is provided on the li...
