Press-type overflow drainage device for water container

A press-type overflow drainage device for water container, comprising:

• a drainage cover mechanism including a drainage cover and a transmission mechanism;
• a lifting control mechanism;
• the lifting control mechanism being provided with up and down movement member and a fixed component with a through hole for the movement of the up and down movement member;
• and
• a connecting steel wire, one end of the connecting steel wire being connected with the up and down movement member, and the other end being connected with the transmission mechanism;
• and
• a horizontal button assembly which is provided with a button, wherein
• the lifting control mechanism provides two upper and lower stop positions, so that the up and down movement member can stop at different heights, operate between the lower stop position and the upper stop position with the help of external force pressing and storing and releasing spring energy, and correspondingly push and pull the connecting steel wire to make the transmission mechanism in a first working state and a second working state;
• the first working state corresponds to the closing or opening state of the drainage cover, and the second working state corresponds to the opening or closing state of the drainage cover;
• the horizontal button assembly is connected with the up and down movement member through a joint member while the corresponding up and down movement member stops in the upper and lower stop positions, and the button has the press-in and stop and pop-up and stop positions at the front and rear of the horizontal position, and the press-in and stop position corresponds to the first working state of the transmission mechanism, and the pop-up and stop position corresponds to the second working state of the transmission mechanism;
• and
• the horizontal button assembly includes a horizontal sliding member, a rotary rod, a shaft and a swing arm, and the button is connected with the horizontal sliding member;
• the swing arm and the driving rod rotate synchronously through a shaft connection;
• the swing arm and the joint member are rotatably connected to both sides of the shaft;
• the horizontal sliding member and the rotary rod are movably clamped with a ball joint;
• and
• the rotatable rod extends from the shaft downwardly.
