It is poor using difficulty, security.
Utility model content
The utility model is in view of the shortcomings of the prior art, there is provided a kind of rational in infrastructure, processing and manufacturing is easy；Accounted for during unlatching
With less activity space；Lower swing arm swing angle is small, and the furnace hole lower part space of occupancy is also small, cover plate open impulsive force also compared with
It is small；The balance jack up hanging object blind patch that cover plate is applied widely, security performance is high.
To realize the utility model purpose, there is provided following technical scheme：One kind balance jack up hanging object blind patch, including
Cover plate housing, the door-plate being hinged with cover plate housing, it is characterised in that vertical rack is installed, under vertical rack below cover plate housing
The be hinged inclined support bar lower end in end, the nearly cover plate housing side in door-plate lower section are hinged swing arm left end, and swing arm right-hand member is provided with balancing weight, tiltedly branch
It is be hinged point articulated between strut upper end and swing arm both ends, vertical rack, door-plate, inclined support bar and swing arm is hinged,
Door-plate, inclined support bar, swing arm relative rotary displacement.
Preferably, inclined support bar upper end is screw telescopic structure, locked after locking nut regulation is installed.
Preferably, it is hinged with secondary door-plate on the outside of door-plate.
Preferably, nearly cover plate housing side, with being provided with rotating shaft on the door-plate of swing arm left end hinged place, swing arm left end is arranged
In in rotating shaft and be machined with installation with door-plate on driving gear meshed gears structure, driving gear connection power source.
The utility model beneficial effect：The utility model covering plate structure is reasonable, and processing and manufacturing is easy；Taken during unlatching less
Activity space；Lower swing arm swing angle is small, and the furnace hole lower part space of occupancy is also small, and the impulsive force that cover plate is opened is also smaller；Lid
Plate is applied widely, security performance is high.
