Description
Technical field
The present invention relates to vehicle-carrying display screen technical fields, and in particular to a kind of turnover mechanism electromagnetic braking component and comprising
Its display screen turnover mechanism.
Background technique
Chinese document CN204646978U (applying date: on 04 29th, 2015) discloses a kind of display manual overturning machine
Structure is related to display.Equipped with friction component, electromagnetic braking component and fixed frame；Friction component be equipped with flange shaft, pedestal, under rub
Pad, upper friction plate, upper cover；Lower friction plate is set on pedestal and is sequentially placed into flange shaft and upper friction plate, and upper cover, which is placed on, rubs
In pad, pedestal and upper lid are by screw fastening and elastic according to required torsion adjusting screw equipped with through-hole, pedestal and upper cover；Electricity
Magnetic brake component is equipped with magnetic yoke lid, coil, magnetic yoke, pressure spring, flange tooth, flange tooth, fore bearing, bearing block, rear bearing, flange
Axis；The fore bearing and rear bearing are inserted in bearing block, and flange shaft passes through rear bearing and fore bearing, then flange tooth is inserted in flange
Axis；Coil is set in magnetic yoke, and magnetic yoke covers magnetic yoke lid, and pressure spring is put into the hole in magnetic yoke, will be set to stopping on flange tooth
Turn hole is directed at the rotation stop pin being set in magnetic yoke and is pushed into magnetic yoke, and magnetic yoke is tightly locked on bearing block.When opening: pressing lower switch, line
Circle is powered, and flange tooth move to carrying flange tooth direction under the magnetic force, until disengaging and flange tooth engagement, and compresses
Spring, flange tooth loses the constraint of flange tooth at this time, and display is broken display with hand, overcome since self weight can fall
Required position is fallen on after frictional force under nature, at this moment unclamps and closes, coil losing electricity, flange tooth loses magnetic force, under the action of pressure spring,
To flange tooth direction move until with flange tooth engagement.When closing: by lower switch, coil is powered, effect of the flange tooth in magnetic force
Lower to move to carrying flange tooth direction, until disengaging and flange tooth engagement, and compression press spring, flange tooth lose the pact of flange tooth
