Description

Technical Field

[0001] The utility model relates to the technical field of air cushion vehicles, in particular to a uniform air bag and an air cushion vehicle. Background Art

[0002] At present, the bag pressure of existing airbag hovercraft is mainly measured by inflating in advance to ensure the bag pressure balance of the hovercraft during operation. When the airbag hovercraft encounters an emergency during operation, the airbag will deform or even rupture, thereby changing the bag pressure of the airbag and causing the hovercraft to tilt. If it is not properly operated, it may capsize. Utility Model Content

[0003] The primary purpose of the utility model is to provide a uniform airbag, so that the airbag pressures of the airbags on both sides are always kept consistent, so as to avoid tilting and ensure safety.

[0004] Another object of the utility model is to provide an air cushion craft using the uniform air bag.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] A uniform airbag comprises an airbag body, a connecting pipe and a three-way air valve. The airbag body is provided with two, and the two airbag bodies are used to be correspondingly arranged on both sides of the hull. The three-way air valve is used to be connected to the inflation port of the hull, and the two airbag bodies are connected to the three-way air valve through the connecting pipe.

[0007] Preferably, the connecting pipe is a rubber hose.

[0008] Preferably, the connecting pipe is fixed to the three-way valve by a buckle.

[0009] Preferably, the three-way air valve is made of stainless steel or aluminum alloy.

[0010] Preferably, the airbag body is made of PVC or Hypalon.

[0011] Preferably, it also includes a connecting ear, which is fixed outside the airbag body and is used to fix the airbag body on the outside of the hull.

[0012] Preferably, the connecting ear is fixed to the airbag body by glue.

[0013] Preferably, the connecting ear is made of PVC or Hypalon.

[0014] A hovercraft comprises the uniform airbag.

[0015] Compared with the prior art, the uniform airbag of the utility model has the following beneficial effects:

[0016] In the utility model, since the two airbag bodies are connected to the three-way air valve through the connecting pipe, the two airbag bodies are interconnected. Therefore, when one of the airbag bodies is damaged, the gas of the other intact airbag body can flow into the damaged airbag body, so that the air pressure of the two airbag bodies is always consistent until it leaks out, which will not cause the hovercraft to tilt and prevent the hovercraft from heeling.

[0020] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0021] In the description of the present utility model, it should be understood that the wording "comprising" used in the present utility model specification refers to the presence of the features, integers, steps, operations, parts / components and / or assemblies, but does not exclude the presence or addition of one or more other features, integers, steps, operations, parts / components, assemblies and / or their groups. It should be understood that when we say that a part / component is "connected" to another part / component, it can be directly connected to the other part / component, or there can be intermediate parts / components. The wording "and / or" used here includes all or any unit and all combinations of one or more associated listed items.

[0022] like Figure 1 and Figure 2 As shown, the utility model relates to a uniform airbag, comprising an airbag body 1, a connecting pipe 2 and a three-way air valve 3, wherein two airbag bodies 1 are provided, and the two airbag bodies 1 are used to be correspondingly arranged on both sides of the hull, and the three-way air valve 3 is used to be connected to the inflation port of the hull, and the two airbag bodies 1 are connected to the three-way air valve 3 through the connecting pipe 2.

[0023] In the utility model, since the two airbag bodies 1 are connected to the three-way air valve 3 through the connecting pipe 2, the two airbag bodies 1 are interconnected. Therefore, when one of the airbag bodies 1 is damaged, the gas of the other intact airbag body 1 can flow into the damaged airbag body 1, so that the air pressure of the two airbag bodies 1 is always kept consistent until it leaks out, and the hovercraft will not be tilted, thereby ensuring safety.

[0024] In this embodiment, the connecting pipe 2 is a rubber hose, so that the connecting pipe 2 can be glued together with the airbag body 1.

[0025] In this embodiment, the connecting pipe 2 is fixed to the three-way valve 3 by means of a buckle, thereby ensuring the stability of the connection between the connecting pipe 2 and the three-way valve 3.

[0026] In this embodiment, the three-way air valve 3 is made of stainless steel or aluminum alloy material, so that the three-way air valve 3 has a strong structural strength, is not susceptible to corrosion, and has a long service life.

[0027] In this embodiment, the airbag body 1 is made of PVC or Hypalon material to have a longer service life.

[0028] In this embodiment, the uniform airbag further includes a connecting ear 4, which is fixed to the outside of the airbag body 1. The connecting ear 4 is used to fix the airbag body 1 to the outside of the hull, thereby facilitating the installation of the airbag body 1.

[0029] Preferably, the connecting ear 4 is fixed to the airbag body 1 by glue to facilitate the arrangement of the connecting ear 4 .

[0030] Specifically, the connecting ears 4 are provided on both sides of the upper part of the airbag body 1 to ensure the stability of the airbag body 1 connected to the outer side of the hull.

[0031] In this embodiment, the connecting ear 4 is made of PVC or Hypalon material to have a longer service life.

[0032] The utility model also relates to an air cushion craft, comprising the uniform air bag.

[0033] The hovercraft adopts the uniform airbag, so that when the airbag body 1 is damaged, the air pressure of the two airbag bodies 1 can be kept consistent until the gas leaks out, thereby preventing the hovercraft from tilting and ensuring safety.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention.
