Drive-by-wire mechanism of double-gear water drainage valve

Abstract

Disclosed is a drive-by-wire mechanism of a double-gear water drainage valve. An all-drainage button and a half-drainage button which are respectively sleeved with two springs are mounted on a button seat side by side, the bottom of the button seat is connected with a drive-by-wire box, press rods at the bottoms of the all-drainage button and the half-drainage button are pressed into the drive-by-wire box, and a movable part which is parallel to a side-by-side direction of the all-drainage button and the half-drainage button is arranged in the drive-by-wire box, and is connected with a pulling rope; shifting devices which respond to pressing of the press rods so as to horizontally drive the movable part in one way are respectively between the all-drainage press rod and the movable part and between the half-drainage press rod and the movable part; an elastic part which leads the movable part to reset is disposed between the shifting devices or the movable part and the drive-by-wire box; and the arrangement and translation direction of the movable part for pulling the pulling rope is parallel to the side-by-side direction of the two buttons, the shifting devices which respond to pressing of the press rods to drive the movable part to move in one way are arranged between the press rod of the all-drainage button and the movable part and between the press rod of the half-drainage button and the movable part, the movable part translates but does not rotate, wire control is more accurate, the pitch between the two press rods is large, pressing surfaces of the two buttons are large, misoperation can be avoided, and the required space for installation is small.

Description

technical field [0001] The invention relates to a thread control mechanism for a wire-controlled drain valve, in particular to a wire-controlled mechanism for a dual-speed drain valve. Background technique [0002] Chinese utility model patent (CN201241381Y) discloses a control device for double drain valves. The pressure receiving part 51 of a swing rod 5 is opposite to the control rod 32 of the full row of buttons 3 and the control rod 22 of the half row of buttons 2. The swing rod 5 The lifting part 52 of the swing rod 5 is connected to one end of the traction rope 6, and the swing rod 5 is swung in different amplitudes through the different pressing strokes of the control rod 32 and the control rod 22, so that the lifting part 52 of the swing rod 5 pulls the pull rope 6 in different ranges. , so that the traction rope 6 produces two different threads to realize the double drainage function of the wire-controlled drain valve; the disadvantage of this control device is: th...

Problems solved by technology

[0002] Chinese utility model patent (CN201241381Y) discloses a control device for double drain valves, a pressure receiving part 51 of a swing rod 5 and a control rod of a row of buttons 3 32 is opposite to the control rod 22 of the half-row button 2, and the lifting part 52 of the swing rod 5 is connected to one end of the traction rope 6, and the swing rod 5 can swing in different amplitudes through the different pressing strokes of the control rod 32 and the control rod 22, so that the swing rod 5 The lifting part 52 of the rod 5 pulls the traction rope 6 with different amplitudes, so that the traction rope 6 produces two different threads, and realizes the double drainage function of the wire-controlled drain valve; the disadvantage of this control device is: the full row of buttons 3 The center distance between the control rod 32 and the control rod 22 of the half-row button 2 is small, so the control rod 32 and the control rod 22 with a small center distance can act together on a small area of ​​the pressure plane 53 on the fork 5, The control rod 32 of the full row of buttons 3 is closely adjacent to the control rod 2 of the half row of buttons 2, so the area of ​​the full row of buttons 3 and the half row of buttons 2 cannot be made very large, so it is easy to cause misoperation when the manual row is pressed; but When setting a large interval between the full row of buttons 3 and the half row of buttons 2, the pressing area of ​​the full row of buttons 3 and the half row of buttons 2 can be made very large, and it is necessary to increase the control of the control rod 32 of the full row of buttons 3 and the half row of buttons 2 The distance between the centers of the rods 22, in this case, if the above scheme is still adopted, the swing rod 5 used will be larger in size and take up a larger space
