Handle, one end is fixed in blind plate and covers, and the other end is connected with described door opening and closing mechanism;
Locking mechanism, is placed in blind plate and covers, and comprises the lock ring being placed in and having opening slot and lockhole in lock ring groove, is fixed on the dunnage baffle plate on handle, through the dunnage of dunnage baffle plate, and extension lever, the locking wrench be connected with extension lever; One end of locking wrench is connected with one end of dunnage by connecting bearing pin, the other end is connected with one end of lock ring by moved end locking screw, the other end of dunnage is connected with the other end of lock ring by fixed end locking screw, position limit pin is on the supporting plate set, be arranged on the limiting board between moved end locking screw and fixed end locking screw, limiting board is connected by alert rod with blind plate lid.
Dunnage described in described lock-ring-type fast-opening blind is arc.
Door opening and closing mechanism described in described lock-ring-type fast-opening blind comprises slide hinge and hinge mobile mechanism, slide hinge and handle affixed, hinge mobile mechanism and cylindrical shell pipe nipple affixed, described slide hinge mobile blind plate lid that drives in described hinge mobile mechanism is movable relative to cylindrical shell pipe nipple.
Hinge mobile mechanism described in described lock-ring-type fast-opening blind is slide way mechanism, and described slide hinge slides in described slide way mechanism and rotates.
Hinge mobile mechanism described in described lock-ring-type fast-opening blind is slideway mechanism, and described slide hinge replaces with roller, and described roller slides and rotates in described slideway.
Described in described lock-ring-type fast-opening blind, position limit pin is placed between dunnage baffle plate and fixed end locking screw.
Lockhole described in described lock-ring-type fast-opening blind is waist-hole type.
In described lock-ring-type fast-opening blind, to the displacement distance of dunnage baffle plate, position limit pin ensures that the displacement distance of connection bearing pin exceedes the dead point be made up of connection bearing pin, moved end locking screw and fixed end locking screw.
The invention lock-ring-type fast-opening blind compared with prior art has following beneficial effect:
1, the invention lock ring type changes up blind plate structure simply, convenient operation, is controlled compression and the resilience of lock ring by the extension lever of locking mechanism.
2, to the displacement distance of dunnage baffle plate, position limit pin ensures that the displacement distance of connection bearing pin exceedes the dead point be made up of connection bearing pin, moved end locking screw and fixed end locking screw, therefore, when opening blind plate, locking wrench will drive extension lever to rebound under the effect of lock ring, plays safety effect.
3, door opening and closing mechanism is arranged to there is hinge mobile mechanism and slide hinge, slide hinge is done relative to the vertical of cylindrical shell pipe nipple and rotary motion in hinge mobile mechanism, the lock-ring-type fast-opening blind of the invention is installed at the pipeline of below opening DN300mm or the opening of storage tank, is convenient to smooth folding and the closedown of blind plate lid.
4, because lockhole makes waist-hole type, the acting force arm of lock ring is increased, make extension lever open locking mechanism time laborsaving.
