Detailed description of the invention
Be further described the utility model below in conjunction with accompanying drawing 1-5: as illustrated in fig. 1 and 2, flat open foldable door 20 comprises door pillar 1, initiatively door leaf 2, Folding wing 3, door lifter 4, linkage 5 and linkage rod slide block mechanism 10.
The upper and lower end portion of door pillar 1 is respectively equipped with upper seat 101 and lower seat 102.Initiatively door leaf 2 is arranged between upper seat 101 and lower seat 102 by bearing, and Folding wing 3 is movably arranged on active door leaf 2 by hinge 32, not in contact with the ground when therefore initiatively door leaf 2 and Folding wing 3 are opened or closed, unsettled operation, road pavement no requirement (NR).
As shown in Figures 3 and 4, initiatively the bottom of the leading portion of door leaf 2 is provided with hinged seat 22 outwardly, and hinged seat 22 is parallel to the ground.The bottom surface of active door leaf 2 rear end is provided with initiatively door bolt 21, initiatively door bolt 21 is perpendicular with ground.The bottom surface of the front end of Folding wing 3 is provided with folding door bolt 31, folding door bolt 31 is also perpendicular with ground, and near active door bolt 21.
Door lifter 4 is arranged on the bottom of door pillar 1.The bottom of door lifter 4 has the line shaft stretched out downwards.
As shown in Figures 3 and 4, linkage 5 and linkage rod slide block mechanism 10 are all arranged on the bottom of flat open foldable door 20, parallel relative to ground.Linkage 5 comprises the first torque arm 6, second torque arm 7.Linkage rod slide block mechanism 10 comprises first connecting rod 11, second connecting rod 12 and slide block 13.
The head end of the first torque arm 6 has axle installing hole, and axle installing hole is connected by key with the line shaft of door lifter 4, makes the first torque arm 6 and realizes detachable being fixedly connected with between line shaft.When line shaft rotates, the first torque arm 6 can be driven to rotate.
Second torque arm 7 has three links.A link of the second torque arm 7 is positioned at the head end portion of the second torque arm 7, and hinged with the end of the first torque arm 6.When the first torque arm 6 rotates, both pin joints can rotate around the head end of the first torque arm 6.Second link of the second torque arm 7 is mutually close with the 3rd link, and is all in the terminal part of the second torque arm 7.Second link of the second torque arm 7 and hinged seat 22 are hinged.
The head end of first connecting rod 11 and the 3rd link of the second torque arm 7 hinged.The head end of end and second connecting rod 12 is hinged.
The middle part of second connecting rod 12 is rotationally connected with active door bolt 21, makes second connecting rod 12 and initiatively door leaf 2 pivot joint.Second connecting rod 12 terminal part is provided with chute 121.
Slide block 13 is embedded in chute 121, and slide block 13 is fixedly connected with folding door bolt 31, and second connecting rod 12 is rotated by slide block 13 Foldable door 3, thus makes Folding wing 3 can do folding rotational motion relative to active door leaf 2.
The operating principle of the flat open foldable door 20 of the present embodiment is:
As shown in Figures 3 and 5, when the line shaft of door lifter 4 rotates forward, the first torque arm 6 can be driven to rotate around its head end, and pull initiatively door leaf 2 by the second torque arm 7, initiatively door leaf 2 be rotated around door pillar 1, thus opens gradually.
Simultaneously, second torque arm 7 can drive the head end of second connecting rod 12 by first connecting rod 11, make second connecting rod 12 while follow initiatively door leaf 2 and move, while the active door bolt 21 of pivot joint rotates in the middle part of it, thus Folding wing 3 can while follow initiatively door leaf 2 and move around door pillar 1, while do folding rotational motion relative to active door leaf 2 under the drive of folding door bolt 31, also open gradually.
When the pivot 321 that Folding wing 3 wraps page 32 does folding rotary motion, slide block 13 outwards can slide along chute 121, makes slide block 13 and folding door bolt 31 to the distance of center circle of pivot 321 from remaining unchanged, also can follow Folding wing 3 together pivot 321 rotate.If slide block 13 and folding door bolt 31 can not be moved, Folding wing 3 pivotally 321 rotations will be hindered, Folding wing 3 cannot be folded.
Otherwise when the line shaft of door lifter 4 rotates backward, meeting drivening rod mechanism 5 and linkage rod slide block mechanism 10 reverse movement, make initiatively door leaf 2 and Folding wing 3 again close.
Above-mentioned embodiment is set forth essence of the present utility model and is illustrated; but should not be considered as restriction of the present utility model; any simple modifications done based on essence of the present utility model; as long as adopt the mechanism be made up of connecting rod and slide block as the power transmission mechanism of folding door, all should fall within the utility model claims.
Certainly, in the utility model, the head end of the first pull bar 11 can also directly be fixedly connected on door pillar 1, and the second torque arm 7 only needs to arrange two links.When active door leaf 2 rotates, the first pull bar 11 all can promote the second pull bar 12 and rotate around active door bolt 21, so promote pivot 321 that Folding wing 3 wraps page relatively active door leaf 2 rotate.
