Detailed description of the invention
Below in conjunction with Figure of description and embodiment, the utility model is further described.
Embodiment 1
This subway hermatic door, be connected with the doorframe be arranged in subway tunnel, comprise large door leaf 1, little door leaf 2 and little door leaf turnover driving mechanism 3, the top of large door leaf 1 is provided with breach, little door leaf is placed in this indentation, there and seals barbed portion between large door leaf and doorframe, this little door leaf bottom and large door leaf hinged, little door leaf turnover driving mechanism 3 drives little door leaf to overturn on large door leaf top.
Little door leaf turnover driving mechanism 3 comprises slide block 31, connecting rod 32 and to be longitudinally arranged on large door leaf and the chute 33 be positioned at below little door leaf, slide block 31 is slidably arranged in chute 33, connecting rod 32 two ends respectively with slide block 31 and little door leaf 2 hinged, little door leaf 2 overturns along with moving up and down of slide block.Little door leaf turnover driving mechanism 3 also comprises one with the worm screw case 34 of manual pulley and the guide rod 35 that can vertically move, guide rod bottom is provided with screw thread and is connected with the worm-drive in worm screw case 34 by this screw thread, worm gear and guide rod is made to form screw pair, guide rod upper end is connected with slide block, manual pulley is connected with the worm screw in worm screw case, rotation manual wheel drives worm gear wheel to make guide rod produce length travel thus pull slide block to move up and down in chute, and little door leaf overturns then.
Transmission direction in order to ensure guide rod is stablized, and large door leaf is provided with some guide holders 36, and guide holder is built-in with the axis of guide, has longitudinal gathering sill 351 in the middle part of guide rod, and guide rod is through guide holder and the axis of guide is positioned at gathering sill.For the ease of installation and maintenance, guide rod is formed by connecting by shaft coupling 354 by top guide bar 352 and lower guide rod 353.
Embodiment 2
This subway hermatic door, be connected with the doorframe be arranged in subway tunnel, comprise large door leaf 1, little door leaf 2 and little door leaf turnover driving mechanism 3, the top of large door leaf is provided with breach, little door leaf is placed in this indentation, there and seals barbed portion between large door leaf and doorframe, this little door leaf bottom and large door leaf hinged, little door leaf turnover driving mechanism 3 drives little door leaf 2 to overturn on large door leaf 1 top.
Little door leaf turnover driving mechanism 3 comprises pull bar 38 and the hinge bar group 37 by cross-articulation in the middle part of two hinge bars 371, the upper end of hinge bar group 37 is connected with large door leaf, the upper end of two hinge bars in this hinge bar group adjacent to each other or away from time, the length of hinge bar group increases or shortens; Hinge bar group is longitudinally arranged at below little door leaf, and the upper end of two hinge bars is two drive ends 78, the lower end of hinge bar by pull bar and little door leaf hinged, little door leaf overturns along with the change in length of hinge bar group.
If only arrange a hinge bar group, enough strokes are had to pull little door leaf to overturn in order to ensure pull bar, then need longer for the length of hinge bar, but after adding the length of hinge bar, after little door leaf to overturn downwards and puts in place by hinge bar group contraction in length, the width of hinge bar is then wider, it is made to affect the folding operation of large door leaf, therefore hinge bar group is set to multiple, and it is longitudinally hinged successively, the upper end being positioned at two hinge bars of hinge bar group is topmost two drive ends, the lower end of one or two hinge bar being positioned at hinge bar group is bottom connected with the lower end of pull bar.The stroke of such pull bar is the change in length sum of multiple hinge bar group, thus for pull bar provides the stroke being enough to drive little door leaf to overturn under the prerequisite not increasing hinge bar length.
