Description

Technical Field

[0001] This utility model belongs to the field of inflatable seat technology, specifically a buoyancy self-balancing multi-chamber inflatable seat. Background Technology

[0002] Inflatable seats are typically made of high-strength, water-resistant PVC or other similar materials. They are inflated to form a buoyant structure that can easily support the weight of the human body in the water, allowing users to comfortably sit in the water or pool and enjoy their leisure time on the water.

[0003] When a large number of people are playing in the water, the water will fluctuate frequently. The fluctuating water will come into contact with the side of the inflatable seat and exert a large thrust on the seat. Since the inflatable seat is filled with air, it is easy to tilt away from that side after being pushed by a large force on one side, causing people to fall into the water. This results in the current problem of low stability when using inflatable seats. Utility Model Content

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This inflatable seat features a cushioning structure. An air cushion is placed at the bottom of the inflatable seat pad, and the interior of the air cushion is divided into two areas by a groove rod. When one side of the air cushion is impacted by water, the air pushes the slide rod to move the air outlet into the other side area. This allows the air inside the impacted side of the air cushion to quickly transfer to the other side, maintaining the balance of the inflatable seat as much as possible, preventing the inflatable seat from tipping over, and improving the stability of the inflatable seat during use.

[0017] 2. This inflatable seat, by setting up an inclined plate, will contact the surface of the inclined plate when the bottom of the air cushion is impacted. The inclined plate can concentrate the impact force of the water surface on the air cushion at the inclined plate, so that less impact force is directly generated on the bottom of the air cushion, further preventing the inflatable seat from tipping over.

[0018] 3. This inflatable seat, by setting a fastening device, fills the air cushion with gas and seals one end of the air cylinder with a round cap. It can be further tightened by pressing the pressure block against the outer surface of the round cap on the outside of the cylinder, so as to prevent the round cap from shifting when the air cushion is filled with gas due to pressure on the outer surface of the air cushion.

[0026] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0027] like Figure 1-5As shown, this utility model provides a technical solution: a buoyancy self-balancing multi-chamber inflatable seat, including an inflatable seat cushion 1, an inflation tube 4 on one side of the inflatable seat cushion 1, a screw cap 5 threadedly connected to the outer surface of the inflation tube 4, a cushioning structure 2 at the bottom of the inflatable seat cushion 1, the cushioning structure 2 including an air cushion 21, the top of the air cushion 21 being heat-fused to the bottom of the inflatable seat cushion 1, a groove 24 inside the air cushion 21 dividing the interior of the air cushion 21 into two regions on the left and right sides of the groove 24, the top of the groove 24 having several rectangular grooves, two air cylinders 22 on the outer surface of the air cushion 21, a round cap 23 threadedly connected to the outer surface of the air cylinders 22, allowing inflation into the two regions inside the air cushion 21 at the two air cylinders 22 respectively. The air-supported seat is rotatably connected to the inner wall of the rectangular groove at the top of the groove rod 24. A coil spring 26 is installed at one end of the rotating shaft 25, and both ends of the coil spring 26 are fixedly connected to one side of the rotating shaft 25 and one side of the inner wall of the groove rod 24, respectively. Two telescopic rods 27 are fixedly connected to the outer surface of the rotating shaft 25. The buffer structure 2 also includes a sliding rod 28, the same number as the rotating shaft 25. The ends of the two telescopic rods 27 at the top of the rotating shaft 25, away from the rotating shaft 25, slide on both sides of the sliding rod 28. The sliding rod 28 slides at the top of the inner wall of the rectangular groove on the outer surface of the groove rod 24. A through hole is opened inside the sliding rod 28, penetrating both ends of the sliding rod 28. Two air outlets 210 are opened at the bottom of the sliding rod 28. Arc-shaped pieces 29 are fixedly connected to both ends of the sliding rod 28 for inflatable seats. When inflating cushion 1, insert the air pump's hose into the air tube 4 on the outer surface of the inflatable cushion 1. Inflate the cushion 1 using the air pump. After inflation, place the cap 5 on the outer surface of the air tube 4 and rotate the cap 5 to connect it to the threaded connection of the cap 5 and the air tube 4, thus sealing the air tube 4. Then, connect the air pump's hose to the two air cylinders 22 on the outer surface of the air cushion 21. Inflate the two areas inside the air cushion 21 using the air pump. After the air cushion 21 is fully inflated, place the round caps 23 on the outer surface of the two air cylinders 22 and rotate the caps 23 to seal the air cylinders 22. When using the inflatable seat, place the inflatable cushion 1 on the water surface. The air inside the inflatable cushion 1 and the air cylinder 21 inflate the cushion 1. Buoyancy allows a person to sit on the inflatable seat 1. When one side of the inflatable seat 1 is impacted by the water surface, it compresses one side of the air cushion 21. This causes the air inside the compressed area of ​​the air cushion 21 to be compressed towards the arc-shaped plate 29 at one end of a slide rod 28. The arc-shaped plate 29 pushes the slide rod 28 to move to the other side. As the slide rod 28 moves, the telescopic rods 27 on both sides slide and extend on the outer surface of the slide rod 28, simultaneously causing the rotating shaft 25 to rotate and the coil spring 26 to deform. At this time, the air inside the compressed area can enter the other side of the area through the through hole on the outer surface of the slide rod 28 and the air outlet 210 at the bottom, causing the air to quickly concentrate on the other side of the compressed area of ​​the air cushion 21, thus inflating more air into the other side of the air cushion 21. When the external force disappears...When the coil spring 26 returns to its original position, it drives the rotating shaft 25 to rotate in the original direction, returning the shaft 25 to its original position. The telescopic rod 27 retracts, driving the sliding rod 28 back to its original position. The gas inside the air cushion 21 enters the two areas of the air cushion 21 evenly through the through holes on the outer surface of the sliding rod 28. By setting the buffer structure 2 and placing the air cushion 21 at the bottom of the inflatable seat 1, the interior of the air cushion 21 is divided into two areas by the groove rod 24. When one side of the air cushion 21 is impacted by the water surface, the gas pushes the sliding rod 28 to move, bringing the air outlet 210 into the other area. This allows the gas inside the impacted area of ​​the air cushion 21 to quickly transfer to the other side, maintaining the balance of the inflatable seat 1 as much as possible, preventing the inflatable seat 1 from tipping over, and improving the stability of the inflatable seat during use.

[0028] Specifically, such as Figure 2-5 As shown, the bottom edge of the arc-shaped piece 29 is arc-shaped. By setting the bottom edge of the arc-shaped piece 29 to be arc-shaped, the resistance of gas entering the arc-shaped piece 29 can be reduced when one side of the air cushion 21 is squeezed. The top end of the telescopic rod 27 is fixedly connected to the positioning piece 211. The positioning piece 211 slides on the outer surface of the slide rod 28. By setting the positioning piece 211, the angle between the top end of the telescopic rod 27 and the slide rod 28 can be further restricted, so as to avoid the angle between the slide rod 28 and the telescopic rod 27 from deflecting as much as possible.

[0029] Specifically, such as Figure 2-5 As shown, inclined plates 212 are fixedly connected to both sides of the bottom end of the air cushion 21. The inclined plates 212 form a certain angle with the bottom end of the inflatable seat cushion 1. When one side of the bottom end of the air cushion 21 is subjected to an impact force, it will come into contact with the surface of the inclined plates 212. The inclined plates 212 can concentrate the impact force of the water surface on the air cushion 21 at the inclined plates 212, so that less impact force is directly generated on the bottom end of the air cushion 21, further preventing the inflatable seat cushion 1 from tipping over.

[0030] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, two fastening structures 3 are provided on the outer surface of the air cushion 21. The two fastening structures 3 are respectively located on the outer surface of the air cushion 21 near the air cylinder 22. The fastening structure 3 includes a circular piece 31. One side of the circular piece 31 is fixed to the outer surface of the air cushion 21 by heat fusion. A rotating rod 32 is rotatably connected to one side of the circular piece 31. A spring 33 is provided on one side of the rotating rod 32. A pressure block 34 is provided at the end of the spring 33 away from the rotating rod 32. The two ends of the spring 33 are fixedly connected to one side of the pressure block 34 and one side of the rotating rod 32, respectively. By setting the pressure block 34, the air cushion 21 is filled with air. After filling the cylinder with gas and sealing one end of the cylinder 22 with the round cap 23, the pressure block 34 can be pulled at each of the two cylinders 22 to control the pressure block 34 to move in the opposite direction of the rotating rod 32 and compress the spring 33. Then, the rotating rod 32 is rotated to control the rotating rod 32 to move to one side of the round cap 23. The pressure block 34 is released and pushed by the spring 33 to press the pressure block 34 against the end of the round cap 23 away from the cylinder 22. By pressing the pressure block 34 against the outer surface of the cylinder cap 23, the cylinder cap 23 is further tightened at the position of the cylinder cap 23 on the outside of the cylinder, so as to prevent the round cap 23 from shifting when the outer surface of the air cushion 21 is subjected to pressure and the internal pressure increases.

[0031] Specifically, such as Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, a positioning rod 35 is fixedly connected to one side of the pressure block 34. The end of the positioning rod 35 away from the pressure block 34 slides on the inner wall of the rotating rod 32. When the pressure block 34 is pulled to move, the positioning rod 35 will slide on the inner wall of the rotating rod 32. The positioning rod 35 can further limit the angle between the pressure block 34 and the rotating rod 32, and prevent the angle of the pressure block 34 from deviating. Several protrusions 36 are fixedly connected to the side of the pressure block 34 away from the positioning rod 35. The protrusions 36 are made of rubber. By setting the rubber protrusions 36, the friction between the pressure block 34 and the outer surface of the round cover 23 can be increased, so that the pressure block 34 is not easy to shift when it presses on the outer surface of the round cover 23.

[0032] The working principle of this utility model is as follows:

[0033] S1. When inflating the inflatable seat cushion 1, insert the air pump's hose into the inflation tube 4 on the outer surface of the inflatable seat cushion 1. Inflate the inside of the inflatable seat cushion 1 using the air pump. After inflation, put the screw cap 5 on the outer surface of the inflation tube 4, and rotate the screw cap 5 to make the screw cap 5 threadedly connected to the outer surface of the inflation tube 4, thus sealing the inflation tube 4. Then connect the air pump's hose to the two air cylinders 22 on the outer surface of the air cushion 21. Inflate the two areas inside the air cushion 21 using the air pump. After the air cushion 21 is fully inflated, inflate the two air cylinders respectively. Place the round cap 23 on the outer surface of the cylinder 22 and rotate the round cap 23 to seal the cylinder 22. Then, pull the pressure block 34 at each of the two cylinders 22 to control the pressure block 34 to move in the opposite direction of the rotating rod 32 and compress the spring 33. Then, rotate the rotating rod 32 to control the rotating rod 32 to move to one side of the round cap 23. Release the pressure block 34 and push the pressure block 34 to press the end of the round cap 23 away from the cylinder 22 through the spring 33. By pressing the pressure block 34 tightly on the outer surface of the cylinder and the round cap 23, the position of the round cap 23 on the outside of the cylinder is further tightened.

[0034] S2. When using the inflatable seat, place the inflatable seat 1 on the water surface. The air inside the inflatable seat 1 and the air cushion 21 gives the inflatable seat 1 buoyancy, allowing people to sit on it. When one side of the inflatable seat 1 is impacted by the water surface, it compresses one side of the air cushion 21. This causes the air inside the compressed area of ​​the air cushion 21 to be pushed towards the arc-shaped piece 29 at one end of a slide rod 28. This pushes the arc-shaped piece 29 to control the slide rod 28 to move to the other side. As the slide rod 28 moves, the telescopic rods 27 on both sides slide and extend on the outer surface of the slide rod 28, simultaneously driving the rotating shaft 25 to rotate. Rotation causes the coil spring 26 to deform. At this time, the air inside the compressed area can enter the other area through the through hole on the outer surface of the slide rod 28 and the air outlet 210 at the bottom. This causes the air to quickly concentrate on the other side of the compressed position of the air cushion 21, allowing more gas to be filled into the other side of the air cushion 21. When the external force disappears, the coil spring 26 returns to its original shape and drives the rotating shaft 25 to rotate in the original direction, returning the rotating shaft 25 to its original position. The telescopic rod 27 retracts and drives the slide rod 28 back to its original position. The gas inside the air cushion 21 will enter the two areas of the air cushion 21 evenly through the through hole on the outer surface of the slide rod 28.
