Description

Foldable doors of vertical type

The utility model belongs to a kind of folding door.

Existing rolling-gate is a plate face structure, and the consumption metal material is many, and the cost height is opened at closing time up and down and often broken down, and push-and-pull is motionless, and performance of ventilating is bad.Existing folding to the left and right sides door, though solved the problem of above-mentioned rolling-gate, because the shared space broad of folding door has reduced effective use width in passageway in the door.

When being to provide a kind of rising, the purpose of this utility model draws the vertical folding door of upholding during decline in.

The method that the utility model is finished is to form the telescopic folding part of door with crossbeam and skewback, the upper end is fixed on the axostylus axostyle of a top, and be fixed on axostylus axostyle on the steel band box on steel band or wire rope be connected, the spring lifting gear identical with the rolling-gate lifting is installed in the steel band box, and the bottom is the part of dress lock.The both sides of crossbeam are equipped with a pair of coaster, with the guide groove adapted, move up and down in guide groove.Thereby realize folding when this folding door rises and draw the function of upholding when drop-down in.

The utility model has the advantages that: simple in structure, easily manufactured, cost is low; Solid and reliable, use flexibly, durable in use; Ventilation, fire prevention, theftproof performance are good; Upwards folding, occupy little space, can improve effective utilization in the passageway of door; The big wicket of hotel, market, institutional settings, school of factory all can adopt.

Fig. 1 is a main structure chart of the present utility model, and Fig. 2 is a right view, and Fig. 3 is the shaft configurations schematic diagram.

Most preferred embodiment of the present utility model: axostylus axostyle (1) is installed in the carrier frame plate (2) that is fixed on the top wall, carrier frame plate is generally made with metal material, as case the folding door that draws in after folding is covered, prevent that dust from dropping on the folding door, on decorateing, seem attractive in appearance.Steel band box (4) is installed on the axostylus axostyle, general symmetry is installed two, also has at center position to install one.The spring lifting gear identical with the rolling-gate lifting is housed in the steel band box, and wire rope (3) is wrapped on the steel band box, and the rope lower end ties up on the crossbeam of bottom of the folding door of being made up of crossbeam (5) and skewback (6).The last end floor beam of folding door is fixed on the axostylus axostyle.When the spring in the steel band box shrank return, wire rope twined and shortens, and distance is drawn between the crossbeam of folding door, is suspended in the carrier frame plate at last.When using folding door, firmly overcome the convergent force when spring is upheld in the steel band box, the bottom of downward sliding door, at this moment, a pair of coaster (8) at two ends, the crossbeam left and right sides moves down in guide groove (7) lining, when folding door is upheld maximum extension position, the bottom of door is near ground, can shut by a lock (11), bolt (9) two ends in the lock box plate (10) of folding door bottom are stuck in the keyhole of both sides guide groove, and door i.e. locking.Use the lock box plate, the bolt sealing wherein, can prevent from that the stranger from reaching into to fiddle with bolt, benefit antitheft, safe and reliable.Equidistant arrangement between the crossbeam is the skewback that utilizes every group of two intersections, and the center of intersection is fixed on the crossbeam, and the mode that two ends are slidingly connected with two crossbeams up and down respectively realizes.End at axostylus axostyle is loaded onto motor, promptly becomes vertical automatic folding door for the electric power automatic switch with this vertical folding door of hand switch.
