Abstract

The utility model discloses an air bridge in which the bridge body is composed of a mesh fabric inner layer (1) in which the inside is formed with an closed inner chamber (3) and a mesh fabric outer layer (2) pasted and covered on the outside of the inner layer (1). A valve (4) communicated to the inner chamber (3) is arranged on the bridge body. The advantages of the utility model are the simple structure, easy usage, light weight and good stability. The utility model is suitable to be applied in wetlands, ice surfaces, marshes and other mountain rescue environments.

Description

The gas bridge

Technical field

The utility model relates to a kind of bridge, especially relates to a kind of pontoon bridge.

Technical background

Existing pontoon bridge mostly is and pre-sets pontic, assembles at the scene.Have plenty of and make casing with steel and be formed by connecting in turn, have plenty of and make the raft body with wood or bamboo and be formed by connecting, also have plenty of the ship that direct use connects side by side and do pontic, these modes all are fixed structures, and weight is also heavier, are used for the setting of the rivers water surface more, the laying time is long, carry inconvenience, the transportation difficulty can't be carried out the field rescue easily under environment such as wetland, ice face, marsh.

Summary of the invention

The purpose of this utility model provides a kind of in light weight, gas bridge of being convenient for carrying, using flexibly, making things convenient for lowered in field environment to rescue.

Technical solution of the present utility model is: a kind of gas bridge, its pontic are formed the folder screen cloth internal layer and outer composition of folder screen cloth that covers outside internal layer of airtight inner chamber by inside, pontic is provided with the air valve that communicates with inner chamber.

Internal layer and the water-tight and air-tight folder screen cloth of outer use are made, and the time spent can not rolled folding packing, and weight is lighter, is easy to carry; During use, inflate to inner chamber, form the pontic that launches, lay quick, easy to use by air valve.

As a kind of optimal way, on outer outer wall, be provided with slipmat, when using pontic, prevent to slip.

Pontic is provided with the safety valve that communicates with inner chamber, prevents the excessive structural damage that causes of gas pressure in the inner chamber.

The pontic periphery is provided with clasp and drawstring, conveniently folds folding binding.

Be provided with pocket on pontic, its inside is provided with an end and the outer fixing rope of pontic, can spur rope, from more remote mobile gas bridge, and convenient the use, rope places pocket at ordinary times, is easy to carry.

Be fixed with in the pontic side and grab rope, conveniently control pontic.

Be respectively equipped with left teat and the right teat that is parallel to each other on the relative both side edges of pontic bottom, can make pontic form the structure of similar catamaran hull like this, the stability of raising pontic prevents the left and right sides upset, can also guarantee pontic smooth-ride in water.

Described left teat and right teat are formed the teat internal layer and outer composition of teat that covers outside the teat internal layer of airtight air cavity respectively by inside.Left and right sides teat also can fold binding easily like this, reduces the volume when carrying.

Described air cavity communicates with described inner chamber, is also inflating the step that simplifies the operation, the convenient use so simultaneously in air cavity to the inner chamber inflation.

The utility model has the advantages that: simple in structure, easy to use, in light weight, carry easily, good stability conveniently is used in and carries out the field rescue under the environment such as wetland, ice face, marsh.

The specific embodiment

Embodiment: shown in Fig. 1,2 and 3, be cuboid after the inflation of gas bridge, its pontic is formed the folder screen cloth internal layer 1 of airtight inner chamber 3 and forms with the folder screen cloth outer 2 that covers outside internal layer 1 by inside, be respectively equipped with the air valve 4 and the safety valve 16 that communicate with inner chamber 3 on the pontic, on outer 2 outer walls, be provided with slipmat 10, on the relative both side edges of pontic bottom, be respectively equipped with left teat 5 and the right teat 6 that is parallel to each other, make pontic form the structure of similar catamaran hull, can improve the stability of pontic like this, prevent the left and right sides upset, can also guarantee pontic smooth-ride in water.

A left side teat 5 and right teat 6 form the teat internal layer 8 of airtight air cavity 7 by inside respectively and the teat skin 9 that covers the teat internal layer outside is formed, air cavity 7 communicates with inner chamber 3, also can in air cavity 7, inflate simultaneously the step that simplifies the operation, the convenient use like this to inner chamber 3 inflations.

Internal layer 1 and outer 2 and teat internal layer 8 and teat skin 9 all use water-tight and air-tight folder screen cloth to make, also can use material such as nylon to make, the time spent can not rolled folding packing, weight is lighter, is easy to carry.

The pontic periphery is provided with eight clasps 13 and five drawstrings 14, conveniently folds folding binding packing behind the pontic.

Be provided with pocket 11 on pontic, its inside is provided with the fixing rope 12 of an end and pontic outer 2, can spur rope 12, from more remote mobile gas bridge, and convenient the use, rope 12 places pocket 11 when flat, is easy to carry.

Be fixed with respectively around in the pontic side and grab rope 15, conveniently control pontic.
