Description

Technical Field

[0001] The utility model relates to the technical field of wall-mounted water tank control, in particular to a novel key structure. Background Art

[0002] A wall-mounted water tank, also known as a hidden water tank, refers to a toilet water tank that is installed in the wall or false wall of the bathroom. In the prior art, if the control panel of the hidden water tank is to be top-mounted and front-mounted at the same time, the transmission bracket used to drive the drain valve in the water tank needs to have two-way pressing driving points. The general transmission bracket adopts a single swing arm structure, and there are pressing points in two directions on the swing arm. The disadvantages are: the position of the pressing points in two directions cannot be flexibly adjusted, resulting in limited arrangement of the pressing points of the control panel; at the same time, one or two pressing points of the transmission bracket are slidably connected to the adjustment sleeve (connected to the adjustment rod), and the contact surface between the two is sliding friction, and the friction force is large. Under long-term use, the product is easy to wear, resulting in an increase in the pressing force of the control panel and a short service life. When the wear is severe, it may also cause product failure. Utility Model Content
