Technical Field
The invention relates to architectural decoration hardware equipment, in particular to a vertical hinged door magnetic attraction type positioning ground shaft.
Background
The vertical hinged door in the public area is often positioned and installed by adopting a ground shaft, so that the vertical hinged door is favorable for bidirectional opening and can realize positioning of three directions. In the prior art, a floor spring is mostly adopted for installing the vertical hinged door in a public area, the floor spring can enable the vertical hinged door to be fixed at a preset closing position and a preset opening position, and a hydraulic device is adopted for the floor spring to enable the speed of the vertical hinged door to be reduced when the vertical hinged door is closed. However, the floor spring is used for pressing the concave-convex shaft of the rotating shaft by virtue of the spring so as to change the positioning position of the vertical hinged door, when the vertical hinged door is closed, the spring is in contact with a concave point of the rotating shaft, the elasticity is smaller at the moment, and when the elasticity is smaller, the vertical hinged door cannot be reset well, so that the vertical hinged door cannot be closed in place well; if the spring force is reinforced, when the vertical hinged door is opened, the protruding point of the rotating shaft is contacted with the spring, the elasticity is gradually increased and reinforced, and the gradually reinforced spring force can cause great effort when the vertical hinged door is opened. In fact, when the floor spring manufactured by the prior art is used for installing the vertical hinged door, the door is very hard to open, if the door is not hard to open by adjusting the spring, the elasticity of the spring must be weakened, and the door is hard to close in place when the door is closed due to the weakening of the elasticity.
