Description
Technical field
The utility model relates to a kind of door leaf, particularly a kind of metal Folding wing with concavo-convex trough rim.
Background technology
In building construction, often use various safety doors, a kind of safety door is that the door of whole fan metal is contained on the doorframe with hinge, this door is suitable for family to be used.If doorframe broad, the gate in shop for example, then inapplicable, another kind claims rolling door again for rolling-gate, the door that is suitable for the StoreFront broad uses, be that batten by several lateral arrangement couples together, with spool it rolled and puts down that the advantage of this rolling-gate is can be installed on the door of broad from the top of doorframe.But it is complicated that not enough place is a structure, and price is higher, and difficulty is installed also, for the very big Men Eryan of width, just needs a plurality of rolling-gates are installed, and when the shop front is narrower, should not use rolling-gate.
Content of the present utility model
The purpose of this utility model provides a kind of metal Folding wing with concavo-convex trough rim, it simple in structure firm, and cost of production is low, installs simply, and is applicable to the shop front of various width.
The purpose of this utility model is the metal Folding wing of realizing by following technical scheme with concavo-convex trough rim, it is characterized in that: it comprises door leaf, hinged hinge, the dual-side of described door leaf is and has the crimping that seals exterior cross-section, wherein, the crimping cross section of one side has Baltimore groove, the crimping cross section of opposite side has the convex slot suitable with this Baltimore groove, is connected with hinged hinge between each door leaf.The sealing profile in described crimping cross section is a rectangle, and described Baltimore groove and convex slot are circular arc.The utility model adopts both sides all to have the sealing exterior cross-section, this has just strengthened the deflection of door leaf, its available thin metal sheet is manufactured and not yielding, concave, convex groove on the crimping is chimeric mutually after assembling, make door leaf close back sound insulation, good every light, dust-separation performance, owing to connect each door leaf with hinge, so for the narrower shop front, or the shop front of broad, all available increase and decrease door leaf number is fit to.Door leaf is the unit piece of manufacturing with flanging process with the metal sheet of monoblock, can be in batch, manufacture in a large number, both guaranteed easily that dimensional accuracy and cost also can reduce.
In sum, the utility model is by adopting the unit door leaf, and door leaf has the structure that the crimping of tongue and groove connects with hinge, and it is simple in structure, installations is simple, cost of production is low and be suitable for the shop front use of various width dimensions.
