Description

Strap formula safety ladder

The utility model relates to buoyant apparatus, particularly a kind of strap formula safety ladder.

The existing lifesaving rope ladder of escaping danger is to be bound by the rope that is same as traditional wooden ladder shape and structure to form.Its defective is that terraced body stent is wide, and it is big to account for the space of crouching, and constitutes the limitation of using; Draw in and when launching, terraced body is easy to twine or tangle, hinder quick use and escape danger; Personnel climb up and down hold up in also difficulty can keep both feet to scrunch and the centre of body weight non-migration along straight line all the time, so very easily in waving of terraced body rocked, slippage is fallen and injures and deaths on ladder, so its safety is relatively poor.

The utility model is at above-mentioned weak point of the prior art, innovative design go out a kind of simple in structure, use quick, safety and be applicable to and use the strap formula safety ladder of convenient harvesting again under the multiple condition.

Task of the present utility model is accomplished according to following technical scheme.

This strap formula safety ladder includes hanger and the following flexible bench that connects constitutes.Hanger can be hook or link, also can be hook or the link that is connected with the rope chain.Selecting material for use can be the engineering plastics of high-strength anti-flaming, but is good with metal material especially.Flexible bench is to be connected in sequence by a plurality of bands.Its band can be with prefabricated a plurality of endless belt windings; Can also cut apart the cross sections that a plurality of length are bandwidth 1/2nd along the belt length correspondence with one or two long bands, and incite somebody to action the back affixed flexible bench that a plurality of bands are arranged that forms of otch grafting in twos in regular turn.First-selected waterproof, fire-retardant, high-intensity webbing are made.

Configuration connects the Tibetan ladder box of one, can directly be connected to the band of flexible bench tail end down, and one also can be formed by connecting by the band of hiding the box chain that is provided with on the terraced box and tail end.

The strap formula safety ladder of the utility model is compared with prior art, and its advantage is: the ladder top is provided with hanger, can make things convenient for hanging support to fix; Flexible bench has a plurality of monomer bands to be formed by connecting, and the terraced width of cloth is suitable for narrow space for a short time to launch to use, widely applicable; The band fabric width of band, but be convenient to scrunch and make flexible bench be difficult for twine and tangle and rapid deployment uses; The Tibetan ladder box that configuration connects both had been convenient to draw in and has been deposited and carry, but had the effect of weight again but flexible bench rapid deployment can't be subjected to the interference of air-flow, current and drift about; Look and use different and adopt waterproof, fire proofing to make, both applicable to weighing down precipice, Luo Jing, drowned, perhaps the lifesaving of multiple dangerous situation such as fire hazard of storied house is escaped danger.

The description of drawings of exemplary embodiments of the present utility model:

Fig. 1 is the overall structure schematic diagram of the strap formula safety ladder of the utility model;

Fig. 2 is the schematic diagram of band linking part in the flexible bench;

Among the figure: hook 1, rope chain 2, hand-held ring 3, band 4, the terraced box 5 in Tibetan, connection strap 6, rivet 7.

The utility model will and be described further in conjunction with the accompanying drawings by exemplary embodiments.

This strap formula safety ladder band includes the hanger that is linked into an integrated entity and constituted by made hook 1 of metal material and rope chain 2 as shown in Figure 1; Split on the rope chain 2 in order to climb the hand-held ring 3 that the person of holding grips; The lower end of rope chain 2 is connecting flexible bench, and this is a series connection band bundle that has a plurality of band 4 monomers to join successively and form.The band 4 at flexible bench end makes it two-phase and links into an integrated entity by hiding box chain set on the terraced box 5 again, is used for splendid attire and draws stacked flexible bench in.This hides terraced box 5, adopts metal material to make, promptly with the weight function.Each band 4 of the flexible bench of fire-retardant material, it joins structure as shown in Figure 2, at two rings the position of touching is bondd around coating along bandwidth with one section connection strap 6, and by splitting on connection strap 6 and four pieces of rivets 7 that wear the endless belt of holding two bands 4 that join, intensity further reinforces the connection.This position is strong, constitutes foot-operated stile.This ladder can be effective to lifesaving in the fire hazard of storied house.

Claims (2)

1, a kind of strap formula safety ladder is characterized in that: the flexible bench that includes hanger and connect down, this flexibility bench system is connected and composed successively by a plurality of bands.

2, according to the described strap formula safety ladder of claim 1, it is characterized in that: dispose the Tibetan ladder box that connects one.
