Description
Technical field
The field, gate that the kind that the present invention relates to hang is feature, particularly relates to a kind of suspension folding door.
Background technology
At present, common large scale door opening gate mainly comprises two kinds, and a kind of is the retractable door of being opened by stretch mode or closing, and another kind is the vertical hinged door of the mode opening and closing by translation.In general, the intensity of retractable door is lower, and the intensity of vertical hinged door is higher, and reliability is strong, and barrier propterty is good.
But, the form that the transmission mechanism of existing vertical hinged door generally adopts plug-in door lifter to be connected with door pillar on door leaf, singly fan vertical hinged door to realize rotarily opening along rotating shaft, door body width is little; On the door opening of large width, electric vertical hinged door cannot be used.If adopt conventional collapsible vertical hinged door that motorized motions mode cannot be used again to open, manpower can only be used to open or close, using very inconvenience; And the auxiliary universal wheel supported must be installed additional can normally use on the Foldable fan of vertical hinged door, require high to the road surface of door opening.
In addition, though the electrically-driven door be currently used on car door also can be used on door opening gate by improving size, all must arrange guide rail or guide groove, mounting structure is complicated, safeguards inconvenience.
In view of this, be very necessary to develop a kind of door body width large, structure is simple, the new type foldable door that road surface installation requirement is low.
Summary of the invention
For the defect of prior art, the object of the invention is to exploitation one and be applicable to door opening width dimensions greatly, without the need to guide rail, guide groove, to the suspension collapsible vertical hinged door of door opening road surface without installation requirement.
For reaching above object, the present invention adopts following technical scheme.
A kind of suspension folding door, comprising: initiatively door leaf, at least one Folding wing, and door pillar; It is characterized in that, described active door leaf is arranged on the door-hinge of door pillar, is provided with the pivoted link mechanism be connected between described Folding wing with active door leaf; The upper and lower end portion of described door-hinge is respectively equipped with upper seat and lower seat, and described active door leaf suspends and is arranged between upper seat and lower seat; Described pivoted link mechanism comprises: the quarter butt be flexibly connected with Folding wing and the rigid toggle be movably connected on quarter butt; Described rigid toggle comprises three not end points on the same line, and two end points and middle end points connect and compose and be mutually cranking arm of angle, crank arm formed angular range between 80 ° to 100 ° for two; An end points of this rigid toggle is connected with quarter butt, and another end points of this rigid toggle is flexibly connected with active door leaf, and the middle end points of this rigid toggle is movably connected on door pillar by pull bar;
Described rigid toggle is " L " shape or " people " font; Three end points of described rigid toggle are column spinner or rotating drum; Described rigid toggle is flexibly connected with quarter butt, pull bar, initiatively door leaf respectively by column spinner or rotating drum;
Described rigid toggle and quarter butt, pull bar, the initiatively movable connection method of door leaf are: on one end of quarter butt, pull bar, be provided with cover T-Ring, active door leaf is provided with joint pin; Described cover T-Ring is socketed on the column spinner of rigid toggle respectively, and described joint pin forms movable installation through the rotating drum of rigid toggle;
The movable connection method of described Folding wing and described quarter butt is: be provided with cover T-Ring in one end of quarter butt, Folding wing is provided with joint pin, and described socket ring set is connected on joint pin; The connected mode of described pull bar and door pillar is: on one end of pull bar, be provided with cover T-Ring, door pillar is provided with joint pin, and the formation activity on joint pin of described socket ring set is installed.
As with improvement, two length of cranking arm of described rigid toggle are the same, and two formed angles of cranking arm are 90 °.
As with improvement, described upper seat comprises: with door pillar hard-wired top holder and the bearing that is arranged on the holder of top; Described top holder is made up of "T"-shaped global formation part or building block, and described bearing to embed in the level board of top holder and fixing by screw riveted joint, and the vertical panel of top holder is riveted on door pillar by screw.
As with improvement, described lower seat comprises bottom seat board, one-body molded on the seat board of described bottom have lower seat axle center and postive stop baffle, outside described lower seat axle center, be socketed with bearing, and a shaft-cup to be inserted in postive stop baffle by card base and is riveted on the seat board of bottom by screw.
As with improvement, described door pillar is provided with driving mechanism, this driving mechanism is connected with active door leaf by actuating arm; Described driving mechanism is the one in motor, man-operated mechanism or internal combustion engine.
As with improvement, described active door leaf is provided with the cylindrical heavy rotating shaft be attached thereto, the bearing fit of this heavy rotating shaft and top holder and bottom seat board, and being formed can the flexible connection of axial rotation.
Further with improvement, described Folding wing is two fans, comprising: first Folding wing hinged with active door leaf and the second Folding wing be hinged on the first Folding wing; First Folding wing is provided with column spinner, and the lever in the middle part of in the of with rotating hole is movably arranged on column spinner, and the two ends of lever are respectively by first connecting rod, second connecting rod and initiatively door leaf and the second Folding wing are flexibly connected.
Compared with prior art, a kind of suspension folding door provided by the invention has following beneficial effect:
One, adopt the rigid toggle of angle between 80 ° to 100 °, exerting oneself of pull bar can be reduced, effectively reduce the consumed power of Folding wing; Meanwhile, between rigid toggle and Folding wing, movable quarter butt is set, makes the maximum folded angle of Folding wing reach 180 °; Especially when angle is at 90 °, when two length of cranking arm of rigid toggle are consistent, not only easily manufactured, and arbitrarily can adjust the width of initiatively door leaf and Folding wing, do not affect folding effect.
