Detailed Description

The invention will be described in further detail with reference to the accompanying drawings 1-8:

referring to fig. 1 and 2, the foldable airbag structure of the present invention mainly includes a main airbag 1, an airbag plug 2 and a sub-airbag. The main airbag 1 and the two airbag plugs 2 form an airbag main body. Referring to fig. 3, the sub-airbag has at least two sub-airbags (sub-airbag one 30 and sub-airbag two 31) which are symmetrically fixed in the airbag main body to divide the airbag main body into at least three independent air chambers. Preferably, the sub-airbag shares a part of the airbag main body with the main airbag 1. Furthermore, the two sub-airbags have the same size, and the end parts of the two sub-airbags do not extend into the airbag plug 2.

Referring to fig. 4, the airbag plug 2 has a truncated cone shape, and when the airbag structure is in an inflated state, the stress condition of the airbag plug 2 is unbalanced, so that an airbag plug seam reinforcing strip 23 needs to be arranged on the outer surface of the airbag plug to prevent the seam formed by manufacturing the airbag plug from cracking. During the manufacturing process, when the airbag plug 2 is combined with the main airbag 1, the reinforcing strip has an angular position requirement, and the projected position of the reinforcing strip in fig. 4 (the longitudinal orthographic projection of the foldable airbag structure) only falls within the range of the sub-airbag 30 or the sub-airbag 31 and is offset by about 20-30 degrees from the center of the sub-airbag, so that the folding and the storage of the airbag plug 2 are not affected.

Referring to fig. 1 and 3-6, the three separate air chambers have separate air inlet ducts and nozzles, respectively. The first sub-air bag 30 and the second sub-air bag 31 are respectively provided with a main air nozzle 16, the main air bag 1 is provided with a reverse air nozzle 17, and the main air nozzle 16 and the reverse air nozzle 17 are identical in structure. Preferably, the main air tap 16 and the reverse air tap 17 are provided with an air tube fixing member 18, and the air tube fixing member 18 is installed on the outer wall of the main airbag 1 for fixing the air tube when the sub-airbag is inflated and deflated. The air charging and discharging operations can be respectively carried out on the three independent air chambers through two main air nozzles 16 and one reverse air nozzle 17.

And a double-head air nozzle assembly 13 is also arranged on the main airbag body. Referring to fig. 5 and 6, the double-head air nozzle assembly 13 includes a double-head air nozzle a, an air nozzle upper sealing cover B, and an air nozzle lower sealing cover C. Preferably, the upper air nozzle sealing cover B is connected with the double-head air nozzle A in a bolt mode, and the lower air nozzle sealing cover C is integrally connected with the double-head air nozzle A in an adhesion mode and then integrally adhered to the outer wall of the main airbag 1.

Double-end air cock subassembly 13 main function is, avoids outside trachea when aerifing for the sub-gasbag in both sides pipeline to produce outside winding to the gasbag main part to reduce the influence factor that is unfavorable for the gasbag to accomodate. The sub-airbag and/or the main airbag respectively have a port (in the direction of an arrow in fig. 4) inside the airbag body, where the connection structure of the pipe and the port is detachable or switchable or convertible.

When using double-end air cock subassembly to aerify, be connected to the outside interface of double-end air cock A (arrow tail direction in fig. 4) with the trachea, then on the air inlet of connecting tube to each sub-gasbag through the inside interface of double-end air cock A (arrow direction in fig. 5), realize the internal connection conversion with sub-gasbag pipeline. If the problem appears in the internal pipeline after long-time use, the accessible is dismantled sealed lid B on the air cock and is repaired or changed internal pipeline, is favorable to the later maintenance. This double-end air cock A structure has realized carrying out the function of outer conversion on thinnest thickness, can not allow better solution conversion problem under the condition of exposing the pipeline to possess and not occupy the thickness space after accomodating, the conversion leakproofness is good, conveniently changes the advantage of impaired pipeline.

Figures 1 and 3-6 show only the preferred embodiment of the bladder configuration and should not be construed as limiting the actual product.

Fig. 7 and 8 show schematic structures of the air bag changing states in the process of inflating and deflating the air bag structure of the present invention, respectively.

When the utility model is inflated, the two sub-air bags are inflated to expand to form the state shown in figure 7, and then the main air bag is inflated to expand. The final air pressure of the sub-air bag is simultaneously influenced by the inflating air pressure of the sub-air bag and the inflating air pressure of the main air bag, and the air pressure of each air chamber can be accurately controlled through the air pressure detection device.

During air release, the main airbag is firstly exhausted to form a state shown in fig. 7, then the sub-airbags are exhausted, in the process of exhausting the sub-airbags, the middle parts of the two sides of the main airbag are properly arranged to be always folded and bent inwards along the middle sewing lines of the two sides, and finally two opposite sigma-shaped folding structures are formed after the sub-airbags are exhausted, wherein the end face parts of the two opposite sigma-shaped folding structures are shown in fig. 7.

When the air bag is in use, the air pressure control system monitors the air pressure of each air chamber at any time. If air leakage occurs, the air leakage can be treated respectively according to different conditions. If the sub-air bag leaks air, the inner film of the sub-air bag is pressed by the pressure of the main air chamber and is tightly attached to the outer wall of the air bag main body, the sub-air bag can be abandoned, and the pressure of the main air chamber is filled to working air pressure, so that the volume of the air bag is not changed, and the buoyancy is not reduced; if the main air bag leaks, the twin air bags can be inflated to working air pressure, and the buoyancy of the air bags is reduced by about 30 percent; in more serious cases, when only one sub-air bag is left to work, the control system gives up other air chambers and charges the pressure of the sub-air bag to the working air pressure, at the moment, the buoyancy of the air bag is left by about 35 percent, and the air bag is still long and rod-shaped and has smaller sailing resistance.

As one of other preferred embodiments, as shown in fig. 1 to 3, a handle 11 is provided on the airbag main body to facilitate the transportation of the airbag.

As one of other preferred embodiments, as shown in fig. 1 to 3, an airbag main body is provided with a tether anchor 20, an oblique hinge connector 21, and a large hinge connector 22. The safety line fixing member 20 is used to connect the airbag main body to the water equipment through the safety line. The inclined hinge connecting piece 21 and the large hinge connecting piece 22 are used for hinging the airbag main body on the water equipment, so that the airbag can be conveniently unfolded, folded, stored and the like.

As one of other preferred embodiments, as shown in fig. 2 and 3, the ventral fin device is attached directly below the airbag of the present invention, and specifically, the ventral fin 5 is attached to the airbag main body by a ventral fin fixing member 7. Preferably, the ventral fin 5 has a sheet structure adapted to the air bag, and is provided with mounting shaft fixing structures along two longitudinal side edges thereof, respectively, and is provided with a plurality of hook holes on the two side edges, and the ventral fin fixing member 7 has a hook structure matched with the hook holes. A plurality of air bag ventral fin hooks are bonded at the designated positions at the two ends of the air bag in advance. When the overwater equipment is used, the mounting shafts on the two sides of the ventral fins of the air bag are respectively hung on the hooks when the air bag is inflated to be full, and then the air bag is full. The ventral fin device can realize the good direction of equipment on water, has improved the ability of shocking resistance of equipment on water, can play the guard action to the gasbag simultaneously.
