Description

Technical Field

[0001] The utility model relates to the technical field of surfboards, in particular to a double-air chamber surfboard. Background Art

[0002] A surfboard is a piece of equipment used for surfing, usually made of materials such as foam, fiberglass, and epoxy resin. The shape and size of a surfboard can vary depending on the surfer's weight, skill level, and the sea conditions being surfed.

[0003] However, most of the existing surfboards are single-chamber surfboards. When the gas in the air chamber leaks due to hitting a reef, it can no longer provide buoyancy support, which is prone to safety accidents. For other double-chamber surfboards, if one of the air chambers is accidentally damaged and leaks, all the gas in the air chamber will quickly leak out, causing the air chamber to completely lose the effect of providing buoyancy support. Therefore, a double-chamber surfboard is needed to solve the above technical problems. Utility Model Content

[0004] The main purpose of the utility model is to provide a double-air chamber surfboard, which can effectively solve the technical problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A double air chamber surfboard, comprising a surfboard body, wherein two groups of air chambers are arranged inside the surfboard body, namely a first air chamber and a second air chamber, wherein the first air chamber is located at the inner periphery of the second air chamber, wherein a plurality of partitions are fixed inside the first air chamber and the second air chamber to divide the interior into a plurality of sub-air chambers, wherein an inflation tube extending into the first air chamber and the second air chamber is fixed on the top surface of the surfboard body, wherein the inflation tube penetrates the partition to each sub-air chamber, and an air outlet is fixed on the inflation tube corresponding to each sub-air chamber.

[0007] As a further solution of the utility model, sealing plates are fixed on both sides of the partition.

[0008] As a further solution of the utility model, a safety valve is fixed on the bottom surface of the surfboard body corresponding to each sub-air chamber.

[0009] As a further solution of the utility model, an inflation cover is fixed to the top surface of the surfboard body at a position corresponding to the inflation tube.

[0010] As a further solution of the utility model, a plurality of elastic rope rings are fixed to the top head of the surfboard body, and elastic ropes can be tied to the elastic rope rings.

[0011] As a further solution of the utility model, a standing area is provided on the top surface of the surfboard body between the elastic rope ring and the inflatable cover, an anti-slip pad is fixed on the standing area, and a handle is provided on the standing area.

[0012] As a further solution of the utility model, a fin is fixed to the tail of the top surface of the surfboard body.

[0013] The beneficial effects of the utility model are as follows:

[0014] 1. Inflate the air tube so that the air outlet heads in each sub-air chamber can vent air to fill the sub-air chamber with gas, and then tighten the inflation cover. At this time, when one of the sub-air chambers in the first air chamber or the second air chamber is damaged and leaks, the sealing plate on the partition can prevent the gas in the adjacent sub-air chamber from leaking. This can prevent the gas in the entire air chamber from leaking out quickly when a certain area in the air chamber is damaged, and it is completely unable to provide buoyancy support.

[0015] 2. The safety valve is located at each sub-chamber, which can release excess gas to prevent the sub-chamber from rupturing when the gas pressure in the sub-chamber is too high. The elastic rope tied to the elastic rope ring can tie the surfer's feet to prevent the surfboard body from separating from the person. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-4 As shown, a double air chamber surfboard comprises a surfboard body 1, wherein two groups of air chambers are arranged inside the surfboard body 1, namely a first air chamber 2 and a second air chamber 3, wherein the first air chamber 2 is located at the inner periphery of the second air chamber 3, and a plurality of partitions 4 are fixed inside the first air chamber 2 and the second air chamber 3 to divide the interior into a plurality of sub-air chambers 5, and an inflation tube 6 extending into the first air chamber 2 and the second air chamber 3 is fixed on the top surface of the surfboard body 1, and the inflation tube 6 passes through the partition 4 to each sub-air chamber 5, and an air outlet 7 is fixed on the inflation tube 6 at a position corresponding to each sub-air chamber 5, and the air outlet 7 located in each sub-air chamber 5 can allow gas to be quickly filled into each sub-air chamber 5, and a plurality of sub-air chambers 5 can be separated by the partition 4 to ensure that when a certain area of ​​an air chamber in the first air chamber 2 or the second air chamber 3 is damaged and leaks, only the gas in the corresponding sub-air chamber 5 will leak out, and the gas in the remaining adjacent sub-air chambers 5 will still be filled, so as to still provide buoyancy support.

[0023] In this embodiment, sealing plates 8 are fixed on both sides of the partition 4. The sealing plates 8 can prevent the gas between adjacent sub-air chambers 5 from circulating with each other, resulting in that when a certain area is damaged and leaks, the entire remaining sub-air chambers 5 slowly leak through the gaps, causing the buoyancy support provided to gradually decrease, until the gas in the sub-air chamber 5 is leaked out and loses its effectiveness.

[0024] In this embodiment, a safety valve 9 is fixed to the bottom surface of the surfboard body 1 at a position corresponding to each sub-air chamber 5. The safety valve 9 can release excess gas when the gas pressure in the sub-air chamber 5 is too high during inflation or use, so that the gas is always maintained in a normal state, thereby avoiding possible deformation, rupture or other damage of the first air chamber 2 and the second air chamber 3 in the surfboard body 1, which may affect the performance and stability of the surfboard body 1.

[0025] In this embodiment, an inflation cover 10 is fixed to the top surface of the surfboard body 1 at a position corresponding to the inflation tube 6. After inflation is completed, the inflation cover 10 is tightened to prevent gas from leaking out through the inflation tube 6.

[0026] In this embodiment, a plurality of elastic cord rings 11 are fixed to the top of the surfboard body 1, and elastic cords can be tied to the elastic cord rings 11. The elastic cords tied to the elastic cord rings 11 can be tied and fixed to the feet of the surfer to prevent the surfboard body 1 from drifting away from the surfer when the surfer falls out of control, thereby preventing safety problems.

[0027] In this embodiment, a standing area 12 is provided on the top surface of the surfboard body 1 between the elastic rope ring 11 and the inflatable cover 10, and an anti-skid pad 13 is fixed on the standing area 12. A handle 14 is provided on the standing area 12. When standing surfing, the surfer steps on the anti-skid pad 13 on the standing area 12 to increase the friction with the surfer's feet and prevent the surfer from losing control due to slipping. The handle 14 is held by the surfer when the surfer lies prone to prevent him from falling under the surfboard body 1, and can be carried or taken away from the surfboard body 1 when it is convenient to reach the shore.

[0028] In this embodiment, a fin 15 is fixed to the tail of the top surface of the surfboard body 1 , and the fin 15 can provide stability for the surfer when surfing.

[0029] It should be noted that the utility model is a double-chamber surfboard. When in use, air is inflated into the inflation tube 6 so that the air outlet head 7 in each sub-chamber 5 releases air to the outside to fill the sub-chamber 5 with gas, and then the inflation cover 10 is tightened. At this time, when a sub-chamber 5 in the first air chamber 2 or the second air chamber 3 is damaged and leaks, the gas in the adjacent sub-chamber 5 can be prevented from leaking out under the action of the sealing plate 8 on the partition 4. In this way, when a certain area in the air chamber is damaged, the gas in the entire air chamber can be prevented from leaking out quickly, and the effect of providing buoyancy support can be completely prevented. The safety valve 9 is located at the position of each sub-chamber 5. When the gas pressure in the sub-chamber 5 is too high during inflation or use, the excess gas can be released to prevent the sub-chamber 5 from rupturing. The elastic rope tied to the elastic rope ring 11 can tie the surfer's feet to prevent the surfboard body 1 from being separated from the person.

[0030] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
