FIELD: plumbing.
SUBSTANCE: invention relates to the field of plumbing devices. A drain mechanism contains hollow case (20) fixed to cover (10) of a drain tank, at least one push button (2) mounted in the hollow case with the possibility of movement by height between an initial position and at least one pressed position, fittings (3) mounted inside the drain tank and connecting overlap means (30) made with the possibility of movement between an overlap position and an opening position of water release hole (11) made in lower wall (12) of the drain tank, and transferring mechanism (4) between one or several push buttons and overlap means. The transferring mechanism contains traction rod (42) connected to overlap means. The traction rod passes through lower channel (21) of the hollow case, and it is made with the possibility of movement by height along the axis of movement T relatively to the hollow case. The transferring mechanism contains a lever return system placed in the hollow case. The lever return system contains lever (41) made with the possibility of rotation around the axis of rotation R, providing the reverse stroke by height of one or several push buttons relatively to the height of the traction rod. The transferring mechanism also contains means (7) for locking the traction rod by height relatively to the hollow case. In the initial position of one or several push buttons, the lever takes a position of locking the traction rod by height. One or several push buttons are connected to the lever to rotate the lever and, after actuating one or several push buttons, to remove it from the locking position. Lever (41) contains gear wheel (410), the center of which is installed on the axis of rotation R. The gear wheel is in engagement with gear rail (200) connected to one or several push buttons (2).
EFFECT: provision of a push-button water drain mechanism with simplified installation.
