Description

Technical Field

[0001] This utility model relates to auxiliary devices for ball sports, and in particular to an inflatable human wall. Background Technology

[0002] In sports training, equipment is often used to replace the human body, such as the human wall in football training. While existing inflatable human walls are convenient to use, they have many shortcomings. For example, the weight distribution at the bottom of a single inflatable human wall is limited, often relying on water to increase weight, resulting in poor flexibility. Furthermore, the small contact area between the bottom and the ground, or an unreasonable structural design, limits stability. Therefore, utility model application number 201721664266.1 discloses an inflatable human wall with an expansion chamber and a weight-increasing chamber. The expansion chamber is annular, with side walls on both sides forming a buffer chamber. The side walls of the buffer chamber have one or more air holes communicating with the outside. The expansion chamber has an inflation valve and an inflation indicator. The weight-increasing chamber is located at the bottom of the expansion chamber and has a water-filling valve and a base plate. The base plate is placed at the bottom of the weight-increasing chamber, making its bottom flat. The expansion chamber, buffer chamber, and weight-increasing chamber are independent and not interconnected. The advantages are: simple structure, easy and convenient use. It can save inflation and deflation time and improve efficiency, and has strong impact resistance and is not easily deformed; the bottom plate at the bottom of the weight-increasing chamber can make the human wall more stable when placed on the ground; the new inflation indicator strip can effectively prevent over-inflation.

[0003] However, in this scheme, if multiple inflatable human walls are used in combination, the connection stability of multiple inflatable human walls is poor when they are arranged. They are placed vertically with only a low center of gravity and are easily affected by external forces (such as the impact of kicking a ball, wind, thrust, etc.) and may tip over or shift. The overall structural strength is insufficient and it is difficult to use stably in complex environments. Utility Model Content

[0027] Reference Figure 1The inflatable human wall of this utility model embodiment includes a main body 100 and a support part 200. The main body 100 has an inflatable cavity 110 and an openable first inflatable port 120. Two support parts 200 are provided, fixed at an angle to the bottom of the main body 100. Each support part 200 has a built-in water cavity 210 and an openable water inlet 211. A magnetic suction part 220 is provided on the side of each support part 200. (Referring to...) Figure 2 Multiple inflatable human walls can be arranged adjacent to each other, and the magnetic suction parts 220 of the two support parts 200 of two adjacent inflatable human walls can fit together and be magnetically connected.

[0028] In use, first inflate the main body 100 into the built-in air chamber 110 through the first inflatable air port 120 on the main body 100, so that the main body 100 expands to form the required human wall shape; then open the water inlet 211 on the support part 200 and inject a certain amount of water into the built-in water chamber 210 of the support part 200, and close the water inlet 211 after the injection is completed. When multiple inflatable human walls need to be arranged, they are placed side by side. At this time, the magnetic attraction parts 220 on the sides of the support parts 200 of two adjacent inflatable human walls will stick together due to magnetic attraction, thereby achieving magnetic connection and completing the adjacent arrangement of multiple inflatable human walls. By inflating the main body 100 and injecting water into the support parts 200, the main body 100 expands and the support parts 200 become heavier, respectively. Injecting water into the support parts 200 increases the bottom weight and improves the stability of a single inflatable human wall. The magnetic connection between adjacent inflatable human walls through the magnetic attraction parts 220 makes multiple inflatable human walls mutually constrain each other and form a whole, further improving the placement stability of multiple inflatable human walls after arrangement, making them less likely to tip over or shift during use.

[0029] In summary, the magnetic connection between the multiple inflatable human walls allows them to restrain each other, improving the stability of the arrangement of the multiple inflatable human walls.

[0030] It is important to emphasize that the magnetic connection method effectively links multiple inflatable human walls into a whole, enhancing the overall structural strength and stability. Besides the impact of kicking a ball, the mutual restraint between the multiple inflatable human walls can also disperse and offset external forces such as wind and thrust when subjected to external forces, reducing the impact on individual inflatable human walls. This improves the placement stability of the entire arranged inflatable human wall, enabling it to be used stably in more complex environments.

[0031] The magnetic suction part 220 is a magnet, and the support part 200 has a closed placement groove 221 inside. The placement groove 221 is located in the water cavity 210, and the magnetic suction part 220 is embedded in the placement groove 221. Embedding the magnetic suction part 220 in the placement groove 221 inside the support part 200, and with the placement groove 221 located in the water cavity 210 and closed, ensures that the magnetism of the magnetic suction part 220 can be effectively exerted to achieve magnetic connection between adjacent inflatable mannequins, while avoiding direct contact between the magnetic suction part 220 and the water in the water cavity 210 and the external environment, preventing the magnet from rusting or weakening, and extending the service life of the magnetic suction part 220.

[0032] In some embodiments, the support portion 200 is narrower at the top and wider at the bottom, with a spherical bottom. When the inflatable mannequin is placed on the ground, the spherical bottom of the support portion 200 contacts the ground. Due to the good rolling and support properties of the sphere, the weight of the support portion 200 can be evenly distributed. The narrow-top-wide-bottom structure increases the width of the bottom, expands the area of ​​the support surface, and lowers the center of gravity, making the object more stable. When placed, the vertical line of the center of gravity can fall more effectively within the support surface, thereby improving the stability of the inflatable mannequin. On the other hand, when the inflatable mannequin needs to be moved, because the bottom is spherical, only a small force needs to be applied to make the inflatable mannequin roll on the ground, facilitating movement.

[0033] Preferably, to further improve stability, a counterweight cavity 230 is also provided inside the support portion 200. The counterweight cavity 230 is relatively independent from the water cavity 210. A counterweight block 231 is embedded in the counterweight cavity 230, which is located at the bottom end of the support portion 200. The counterweight cavity 230 and the counterweight block 231 further increase the weight at the bottom end of the support portion 200, lower the center of gravity of the entire inflatable mannequin, and improve its anti-tipping ability. Even when the water volume in the water cavity 210 changes, the fixed weight of the counterweight block 231 can ensure that the bottom end of the support portion 200 has a certain counterweight, thereby ensuring the stability of the inflatable mannequin. At the same time, the counterweight cavity 230 is relatively independent from the water cavity 210, avoiding direct contact between the counterweight block 231 and water, preventing the counterweight block 231 from rusting or being corroded by water, and extending the service life of the inflatable mannequin.

[0034] In addition, in some embodiments, handles 130 are fixedly installed on both sides of the main body 100 for easy handling.

[0035] It should be mentioned that the surface of the main body 100 is provided with an inflation indicator 140, the two ends of which are fixedly connected to the surface of the main body 100. The inflation indicator 140 is made of a pressure-sensitive color-changing material. When air is inflated into the inflation chamber 110 of the main body 100, the pressure inside the inflation chamber 110 gradually increases with the increase in air volume, and the pressure on the inflation indicator 140 also increases. The pressure-sensitive color-changing material will change color according to the pressure change. The operator can observe the color change of the inflation indicator 140 to understand the pressure inside the inflation chamber 110 in real time. When the color reaches the preset standard, it indicates that the required air volume has been reached, and inflation is stopped.

[0036] Preferably, the main body 100 and the support part 200 are integrally formed. When manufacturing the inflatable human wall, an integral molding process is used, manufacturing the main body 100 and the support part 200 as a single unit, eliminating the need for subsequent assembly. This eliminates the weak link of the connecting parts 300 in traditional assembly methods, enabling the inflatable human wall to better withstand external pressure and tension, and improving the overall structural performance.

[0037] In some specific embodiments, to further improve placement stability, the inflatable human wall also includes a connecting portion 300. Between two adjacent inflatable human walls, both ends of the connecting portion 300 are detachably connected to the two inflatable human walls respectively. The connection portion 300 provides a detachable connection method between adjacent inflatable human walls, which not only enhances the connection strength between multiple inflatable human walls, making them form a more stable whole, but also facilitates disassembly and rearrangement when needed.

[0038] Preferably, the side wall of the main body 100 is provided with a slot 150, and the end of the connecting part 300 is embedded in the slot 150 and fixedly engaged with the slot 150. This locking and fixing method between the slot 150 and the end of the connecting part 300 enables quick connection and disassembly between the connecting part 300 and the main body 100, improving assembly and disassembly efficiency. The locking structure has a certain locking force, ensuring that the connecting part 300 will not easily fall off during use, enhancing the connection stability between adjacent inflatable mannequin walls.

[0039] Furthermore, the connecting part 300 is connected to one end of the main body 100 near the support part 200. This allows the connection point to be closer to the bottom of the inflatable wall, reducing the height of the stress point of the connecting part 300, thereby reducing the bending moment and torque experienced by the connecting part 300 and improving the stability and reliability of the connection.

[0040] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
