Description

Technical Field

[0001] The invention relates to a double-row button drain valve adopting a low-friction and labor-saving lifting mechanism. Background Art

[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 bracket, wherein the button seat is installed on the drain valve body, and the lever assembly, the lifting rod, the floating barrel and the bracket are assembled in the drain valve body. When flushing, the button is pressed to activate the lever assembly, and the lever assembly drives the lifting rod to lift upward, and the water sealing sheet is lifted to achieve flushing.

[0003] The lifting rod that lifts or drops the water sealing plate to the drain outlet is aligned with the barrel bracket in the drain valve. The alignment structure is generally a groove for alignment on the barrel bracket, and a convex strip that slides up and down along the groove is arranged on the lifting rod. During the use of the drain valve, the convex strip of the lifting rod and the groove of the barrel bracket will constantly generate friction. If the up and down movement of the lifting rod can be guaranteed to be vertical, the friction will be very small.

[0004] In the structure of the existing drain valve, its lever assembly is a structure that applies force to only one side of the pull rod, so the force it applies is unbalanced. During use, it cannot be guaranteed that the up and down movement of the pull rod is vertical, which will produce a lot of friction, making it difficult to press the flushing button. The constant friction also makes the components easily damaged, shortening the service life of the components. Summary of the invention

[0005] The purpose of the present invention is to provide a double-row button drain valve with a low-friction and labor-saving lifting mechanism to solve the problems existing in the existing drain valve lever assembly structure.

[0006] The objective of the present invention is achieved as follows: a low-friction and labor-saving drain valve lifting mechanism is arranged in a drain valve body, a button seat is installed on the drain valve body, and a float assembly which cooperates with the lifting mechanism to drain and shut off water is arranged in the drain valve body; the lifting mechanism comprises a button, a driving member, a supporting swing arm, a pulling rod and a lifting rod; the driving member is installed on the lower side of the button, and the driving member is formed with two pressure rods downward; there are two supporting swing arms, and the two supporting swing arms are hinged with the same horizontal axis as the button seat to form an X-shaped supporting structure, the upper end of each supporting swing arm is respectively supported and connected to the pressure rod of the driving member, and the lower end of each supporting swing arm is respectively hinged with the pulling rods arranged on both sides of the lifting rod; the two supporting swing arms are simultaneously driven by the two pressure rods of the driving member to swing in opposite directions, thereby driving the pulling rods on both sides to simultaneously pull the lifting rod to form a vertical lifting balance structure of the lifting mechanism.

[0007] The present invention adopts a double-row button drain valve with a low-friction and labor-saving lifting mechanism. A button seat is installed on the drain valve body, and a half-row float assembly and a full-row float assembly are arranged in the drain valve body for cooperating with the lifting mechanism to drain and shut off water; the lifting mechanism comprises a half-row button, a full-row button, a driving member, a supporting swing arm, a pulling rod and a lifting rod; the driving member is installed on the lower side of the half-row button and the full-row button arranged side by side, and the driving member is formed with two pressure rods downward; there are two supporting swing arms, and the two supporting swing arms are connected to the button seat at the same time. A horizontal axis is hinged to form an X-shaped support structure, the upper end of each supporting swing arm is respectively connected to the pressure rod support of the driving member, and the lower end of each supporting swing arm is respectively hinged to the pull rods arranged on both sides of the lifting rod; the two pressure rods of the driving member simultaneously drive the two supporting swing arms to swing in opposite directions, thereby driving the pull rods on both sides to pull the lifting rods at the same time to form a vertical lifting and pulling balance structure of the lifting mechanism; the lifting rod is connected to the water sealing assembly, and the water sealing assembly is cooperated with the base assembly of the drain valve body to form the drainage and water closing structure of the double-row button drain valve.

[0008] The present invention truly realizes the vertical balanced lifting of the lifting mechanism through the double-rod linkage drive structure, thereby ensuring that the up and down movement of the lifting rod is vertical, reducing friction, achieving the purpose of pressing effort, and further extending the service life of the product and reducing the failure rate.
