Abstract

The utility model relates to an inner bag type high strength air bag, which is composed of an inner bag (1), an outer sleeve (2), a sleeve cover (3) and an air tap (4). The inner bag is a plastic gas closed container, one end of the inner bag is communicated with the air tap, the outer sleeve is woven and wound with vinylon pressed with raw rubber or other high strength synthetic fibre curtain thread cloth or canvas, or is lapped with two layers or three layers additionally, each layer is a single layer structure or a multi-layer structure, after the outer sleeve is shaped on a moulding bed, and the outer sleeve is vulcanized with high-temperature and high-pressure. The air bag has the advantages of good air tightness, high strength, and good repair.

Description

The liner type air bag with high intensity

The utility model relates to the liner type air bag with high intensity, more particularly is exactly to be used for boats and ships up and down water, carrying heavy goods, the air bag with high intensity of salvaging a sunken ship etc. and to be made up of inner bag and overcoat.

At present, existing air bag, air-bag for ship particularly, the disclosed lap jointing type of CN2091272U is arranged, inner tube of a tyre cover tire winding-type, the disclosed inner tube of a tyre cover tire of CN2051902 Weaving type, type tire winding-type, five kinds of no type tire winding-types etc., wherein the product of two kinds of lap jointing type and no type tire winding-types has dropped into practicality, and on market, sell, surplus person is the not high or too short not stock production of practical value that lacks of life-span because of intensity.The air bag that uses in sale and the reality on the market does not have inner bag, leakproofing material and stressed material combine together, so just have two big shortcomings: the one, and big product, no compression molding equipment, single-piece manual production, air-tightness that cannot say for sure to demonstrate,prove air bag, gas leak phenomenon ubiquity; The 2nd, repair poor performance, be difficult to repair if any damage.

The purpose of this utility model provides a kind of liner type air bag with high intensity, and this air bag can overcome the shortcoming of above-mentioned air bag, and manufacture craft is simple, intensity is high, easy repairing, life-span are long.

Above-mentioned purpose is to realize like this, the liner type air bag with high intensity, by inner bag, overcoat, the gentle composition of chewing of outer upper shield, inner bag is the confined gas container made from rubber or plastics that plasticity is arranged, a ventilation mouth, the outer upper shield of overcoat and capsule head is by the vinylon that is pressed with rubber or other high strength synthetic fibre cord cloth or canvas braiding and twines, perhaps adding overlap joint again forms, after moulding on the moulding bed, form through the whole sulfuration of High Temperature High Pressure, it is the primary structure member of air bag, the outer upper shield of overcoat and capsule head is pressed with the vinylon of rubber by two levels or tri-layer, or other high strength synthetic fibre cord cloth or canvas constitute, and described two levels are formed, first level is the above-mentioned cord cloth that is pressed with rubber from inside to outside, or canvas intersection or direction of warp and weft braid, bearing longitudinal pulling force and lateral pull, second level is to be pressed with the above-mentioned cord cloth of rubber, or the spiral winding layer of canvas, bear lateral pull.First level that its tri-layer is formed is to be pressed with the above-mentioned cord cloth of rubber or the backplane level that canvas is reeled, cord is vertically arranged, to bear longitudinal pulling force, second level is that the above-mentioned cord cloth or the canvas that are pressed with rubber intersect or the direction of warp and weft braid, both born longitudinal pulling force, bear lateral pull again, tri-layer is by above-mentioned cord cloth that is pressed with rubber or the spiral winding layer of canvas, bears lateral pull.Above-mentioned each level can be single layer structure or multiple-structure, uses according to reality the requirement of strength of air bag is selected.After the moulding, the High Temperature High Pressure sulfuration.

The utility model can be made different shape and size according to the needs that use, as cylindrical, spherical, bore cylindricality etc.

The utility model can not leak gas because of the airtight inner bag of plastic material system is arranged, and overcoat and Nang Toutaogai are pressed with high strength cord cloth or the canvas braid and the winding layer of rubber or also have bonding layer, and it is strong to bear the vertical, horizontal pulling force, stressed even, the intensity height.Inner bag, overcoat can be repaired respectively if any damaging, and make simply, and the life-span is long.

Fig. 1 is the example block diagram according to a kind of cylindrical air bag that the utility model proposes.

Shown in Figure 1, cylindrical air bag is by the columniform inner bag 1 of a double headed roller circular cone, one is being overlapped the inner bag overcoat 2 identical with the inner bag shape, two outer upper shields 3 that are connected on the circular cone of overcoat two, form with the valve of adorning in the capsule head 4, a valve communicates with inner bag, at last attaching air valve and air-pressure gauge, pressurized air charges into the air bag inner bag from this valve, on another valve, adorn one silently, inner bag 1 usefulness rubber is made, and the outer upper shield of overcoat and capsule head is made up of the vinylon cord cloth of rubber two laminations, from inside to outside, ground floor is that the vinylon cord cloth interlacing that is pressed with rubber becomes, the second layer is with being pressed with the spiral winding layer of vinylon cord cloth of rubber, it be on the moulding bed by above-mentioned level moulding after, the whole sulfuration of heating and pressurizing forms in vulcanizing tank.The burst pressure of this liner type air bag with high intensity reaches 0.6MPa.

This liner type air bag with high intensity container is applicable to automobile, train, the steamer of loading to be specially adapted to the upper and lower water of freighter, also is applicable to large-scale heavy part lifting.
