Description

Technical Field

[0001] This application belongs to the field of airbags, and specifically relates to a floating airbag with a partition chamber. Background Art

[0002] After being inflated, the airbag can be used to increase buoyancy and serve as a floating object on water to carry other mechanisms. Basically, the existing airbag has an inflation chamber inside. Once the outer wall of the airbag is scratched, air leakage is likely to occur. To solve this problem, it is mostly to avoid the outer wall being scratched by increasing the thickness of the outer wall or changing the material of the outer wall. The first method increases the weight of the airbag, and the second method increases the cost of the airbag. Utility Model Content

The interior of this application is partitioned into several independent partition chambers. In this way, when cycling in water, if accidentally scratched, the airbag will not completely leak air and lose buoyancy, increasing the safety of cycling on water. Through the setting of the partition chamber, a balance can be achieved in terms of the weight and cost of the airbag.

[0004] The technical solution adopted by this application to solve its existing problems is:

[0005] A floating airbag with a partition chamber, including an outer wall, and a partition board is arranged inside the outer wall. The partition board divides the interior of the outer wall into several independently arranged partition chambers.

[0006] An air charging and discharging valve is arranged on the outer wall, and several external corresponding holes are arranged on the air charging and discharging valve. The external corresponding holes are connected to each partition chamber through air charging and discharging pipes one by one in a penetrating manner.

[0030] The attached drawing is the best embodiment of a floating airbag with a separation cavity. The present application will be further described in detail below with reference to the attached drawing.

[0031] A floating airbag with a separation cavity, consisting of Figures 1 to 5 As shown, it includes an outer wall 1. Inside the outer wall 1, there is a partition board 2, and the partition board 2 divides the inside of the airbag into several independent separation cavities 3. In this way, when cycling in water, if it is accidentally scratched and broken, it will not completely leak air and lose buoyancy, increasing the safety of cycling on water.

[0032] The outer wall 1 is provided with an air charging and discharging valve, and the air charging and discharging valve is connected to each partition chamber 3 through respective air charging and discharging pipes 4 in a penetrating manner.

[0033] The air charging and discharging valve includes a valve body 6. Two spaced-apart snap rings 12 are fixedly sleeved outside the valve body 6, and the two snap rings 12 are clamped on the inner and outer sides of the outer wall 1.

[0034] The bottom of the valve body 6 is sealed and the upper end is open. A plurality of outer corresponding holes 604 are provided on the circular shaft surface of the valve body 6 located inside the outer wall 1. The outer corresponding holes 604 correspond to and are connected to each air charging and discharging pipe 4 in a penetrating manner.

[0035] An internally threaded pipe 603 is provided above the valve body 6. A sealing plate 602 is provided at the middle position inside the valve body 6, and a through hole is provided in the middle of the sealing plate 602.

[0036] A sleeve 601 is vertically provided on the bottom surface of the valve body 6. A slide bar 7 is slidably provided inside the sleeve 601. A blanking plate 8 is coaxially fixed in the middle of the slide bar 7. A lower sealing liner 801 is sleeved on the circular shaft surface below the blanking plate 8, and a plurality of inner corresponding holes 802 are provided on the lower sealing liner 801.

[0037] A spring 11 is sleeved on the slide bar 7 below the blanking plate 8. Under the push of the spring 11, the top surface of the blanking plate 8 abuts against the bottom surface of the sealing plate 602, blocking the through hole on the sealing plate 602. At this time, the inner corresponding holes 802 are located above the outer corresponding holes 604, and the two are arranged staggeredly.

[0038] A pressing ring 9 is sleeved on the outer side of the top of the slide bar 7. The pressing ring 9 is fixedly connected to the slide bar 7 through a connecting rod 10, and the outer wall of the pressing ring 9 abuts against the inner wall of the internally threaded pipe 603.

[0039] The air charging and discharging valve is detachably connected to the end of an external air pipe through an adapter device. The adapter device includes an externally threaded pipe 13, a reducing pipe 14, and an upper end head 15 that are fixedly connected coaxially in sequence. The upper end head 15 is connected to the end of the external air pipe, and the two can be connected by a quick connector or other existing connection methods.

[0040] The externally threaded pipe 13 is threadedly connected to the internally threaded pipe 603. When the two are threadedly connected, the externally threaded pipe 13 moves downward, pressing down the pressing ring 9, and then pressing down the blanking plate 8 to open the through hole on the sealing plate 602. After the blanking plate 8 moves downward, the inner corresponding holes 802 and the outer corresponding holes 604 are arranged correspondingly and are connected in a penetrating manner. The upper end of the inner corresponding hole 802 extends to the upper surface of the blanking plate 8. After the through hole is opened, the external gas flows into each partition chamber 3 through the through hole, the inner corresponding holes 802, the outer corresponding holes 604, and the air charging and discharging pipes 4 for inflation.

[0041] After inflation is completed, remove the adapter device. The blanking plate 8 moves upward to block the through hole. The inner corresponding hole 802 and the outer corresponding hole 604 are arranged staggeredly. The charging and discharging pipe 4 is blocked and air cannot be released. Each partition chamber 3 is sealed.

[0042] After removing the adapter device, cover the upper part of the internal threaded pipe 603 with the sealing cover 5 to prevent foreign matters or water from entering.

[0043] Two groups of hanging rings 16 are provided at the top of the outer wall 1. Each group of hanging rings 16 contains at least two single hanging rings 16. The hanging rings 16 are used for fixedly connecting with a bicycle through a connecting device.

[0044] The embodiments of the present application have been described in detail above with reference to the accompanying drawings. However, the present application is not limited to the above embodiments.
