Abstract

The utility model relates to a dropping prevention safe and protecting device of an upper folding door, mainly comprising a door panel and a U-shaped sliding groove; two side edges of the door panel are respectively arranged in the U-shaped sliding groove, bracket plates are arranged at the two side surfaces of the door panel, a clamping block and a torsion spring are arranged on the bracket plates, one ends of the clamping blocks are connected with the surfaces of the bracket plates, and the left and right sides of the other ends of the clamping blocks are respectively provided with lugs and clamping heads, one side surface of the U-shaped sliding groove is uniformly provided with a plurality of arc beads from up to bottom, and the arc beads and the lugs of the clamping blocks are leaned against with each other or are separated from each other, and the other side surface of the U-shaped sliding groove is uniformly provided with a plurality of clamping openings from up to bottom, and the clamping openings and the clamping heads of the clamping blocks are clamped with each other or are separated from each other, when the upper folding door falls off suddenly, the arc beads on one side surface of the U-shaped sliding groove push the lugs of the clamping blocks rapidly, and the clamping blocks are thrown into the clamping openings on the other side surface of the sliding groove, so as to prevent the upper folding door from falling off. The device has simple structure, the manufacturing cost is low and the safety is high.

Description

Go up the falling-proof safety device of folded door

Technical field

The utility model relates to a kind of folded door of, and is a kind of falling-proof safety device of folded door specifically.

Background technology

Along with The development of architecture, the gate of increasing mansion, factory, dwelling house adopts the folded door of going up of electronic control, for the sake of security, generally all can dispose and prevent the sliding device of the folded student.Tradition all is an additional sliding door mechanism on last folded door, not only complex structure, inconvenience is installed, also influenced the overall appearance of door.The disclosed a kind of anti-whereabouts safety guards of folded door of the patent No. 200710025074.0, the device construction complexity, extension spring is in extended state for a long time, mechanism easily lost efficacy, and make loaded down with trivial details, easy care not, cost height.

Summary of the invention

The purpose of this utility model is the shortcoming that exists in the prior art in order to overcome, and a kind of compact conformation, safe and reliable is provided, and prevents the safety locking motion that folded door falls suddenly.

In order to achieve the above object, the technical solution adopted in the utility model is: it mainly comprises door-plate, " U " shape chute, the dual-side of door-plate places respectively in " U " shape chute, its technical characterstic is that described door-plate two sides are equipped with supporting plate, supporting plate is provided with fixture block, torsion spring, one end of fixture block connects supporting plate plate face through torsion spring, a fixture block other end left side, right both sides are respectively equipped with lug and dop, the lug that one side of described " U " shape chute evenly is provided with a plurality of arc fins and fixture block from top to bottom is and offsets or released state, and the dop that the another side of " U " shape chute evenly is provided with a plurality of bayonet sockets and fixture block from top to bottom is chucking or released state.When upward folded door sharply falls, the lug of fixture block through the torsion spring effect, is beaten the dop of fixture block to " U " shape chute side that is provided with bayonet socket under the arc fin of " U " shape chute one side promotes fast, in the bayonet socket of the dop of fixture block is snapped in " U " shape chute, prevent that the folded student from falling; Behind the chucking, gently carry on folded every plate, the dop of fixture block is deviate from the bayonet socket of " U " shape chute, goes up folded door and can freely rise, descend.

Further, a plurality of bayonet sockets of a plurality of arc fins of described " U " shape chute one side and opposite side are provided with respectively at interval.

When folded door sharply falls in the utility model utilization, the arc fin of " U " shape chute one side promotes the lug that the door-plate side has the fixture block of torsion spring fast, fixture block is beaten to " U " shape chute another side, in the dop of fixture block is snapped in " U " shape chute another side bayonet socket, prevented that folded door from falling suddenly, security insurance, and it is simple in structure, and cost is low, and is safe in utilization, be convenient to install, safeguard and change, be fit to generally promote the use of.

Description of drawings

Structural representation when Fig. 1 does not fall for folded door of the present utility model;

Fig. 2 is the structural representation of when folded sharply the whereabouts fixture block tightens of the present utility model.

Among the figure: door-plate 1, supporting plate 2, fixture block 3, torsion spring 4, dop 5, bayonet socket 6, lug 7, arc fin 8, " U " shape chute 9.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1, a kind of falling-proof safety device of folded door shown in 2, it mainly comprises door-plate 1, " U " shape chute 9, the dual-side of door-plate places respectively in " U " shape chute, the door-plate two sides are equipped with supporting plate 2, connect torsion spring 4 on the supporting plate 2, one end of fixture block 3 connects supporting plate plate face through torsion spring, a fixture block other end left side, right both sides are respectively equipped with lug 7 and dop 5, one side of " U " shape chute evenly is interval with a plurality of arc fins 8 from top to bottom, the lug 7 of arc fin and fixture block offsets as shown in Figure 1, separate as shown in Figure 2, the another side of " U " shape chute evenly is interval with a plurality of bayonet sockets 6 from top to bottom, and bayonet socket separates as shown in Figure 1 with the dop 5 of fixture block, tighten as shown in Figure 2.

When accident takes place, going up folded door falls suddenly, the lug 7 of fixture block is under the arc fin 8 of " U " shape chute 9 one sides promotes fast, through torsion spring 4 effects, with 3 dozens of fixture blocks to " U " shape chute 9 another sides, the dop 5 of fixture block is snapped in the bayonet socket 6 of " U " shape chute 9 another sides, thereby prevent that folded door from falling suddenly, causes unexpected injury.

Claims
