Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of sports fitness equipment, and particularly relates to an indoor surfboard. BACKGROUND

[0002] With the popularity of national fitness, the indoor surfboard has become an important equipment for urban fitness and entertainment due to its advantage of not being restricted by geographical environment. The existing indoor surfboard is usually composed of a base, an air bag and a balance board. The air bag at the bottom of the balance board is pressed by the force generated by the user stepping on the balance board, so as to simulate an unstable support surface (similar to sea waves or dynamic balance challenges in skateboarding), and force the human body to maintain balance by dynamically adjusting the center of gravity. This process activates deep muscle groups and enhances neuromuscular coordination, thereby achieving functional training effect.

[0003] The current indoor surfboard generally adopts a rubber air bag support structure. However, the rubber air bag gradually loses elasticity after long-term repeated compression. The support effect is obviously decreased after half a year of use, and the air bag needs to be frequently replaced. A single surfboard usually needs to be installed with 2-3 air bags, and the cost of replacing the entire set of air bags exceeds 20% of the total price of the equipment. In addition, the discarded air bags are difficult to recycle, causing environmental pollution. Moreover, the rubber becomes soft when heated and hard when cooled. In an air-conditioned room or an environment with large temperature difference between seasons, the stability of the surfboard will fluctuate greatly with temperature changes. The physical properties of the air bag make it difficult to quantitatively adjust the stability of the surfboard, and the user needs to adjust the air pressure through repeated trial and error to find the appropriate hardness. Therefore, the utility model provides an indoor surfboard structure which does not need to frequently replace the support parts, reduces maintenance cost, and can accurately control the stability of the surfboard body.

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0020] EMBODIMENT

[0021] Please refer to Figs. 1-3 The utility model provides the following technical scheme: an indoor surfboard, including surfboard body 1 and base 2, base 2 top is seted up with positioning groove 3, positioning groove 3 inside evenly is installed with conical spring 4, conical spring 4 top and bottom end are all fixed with fixed support 5, and conical spring 4 is connected surfboard body 1 and base 2 through fixed support 5, and surfboard body 1 periphery and base 2 periphery evenly are installed with adjustable buckle strap 6.

[0022] In order to realize that conical spring 4 is between surfboard body 1 and base 2 high efficiency and stable support, utilizes its variable stiffness characteristics better simulation sea wave fluctuation, ensures the rationality of pressure transmission, in the embodiment, as a preferred technical scheme of the utility model, the small diameter end of conical spring 4 is connected with the bottom surface of surfboard body 1 through the corresponding fixed support 5, and the large diameter end is connected with the groove bottom of the positioning groove 3 of the top surface of base 2 through the corresponding fixed support 5.

[0023] In order to ensure that in the long-term complex dynamic stress environment, the connection of fixed support 5 and surfboard body 1 and base 2 is stable and reliable, reduces the equipment failure caused by loose connection, improves the durability of the overall structure, in the embodiment, as a preferred technical scheme of the utility model, fixed support 5 is fixedly connected with surfboard body 1 and base 2 through bolts respectively.

[0024] In order to guarantee the stability of surfboard body 1 as a whole, while taking into account the convenient handling and storage after use, prevent water leakage from affecting the performance of the equipment during use, in the embodiment, as a preferred technical scheme of the utility model, base 2 is a hollow water injection structure, and a water injection port is formed at one end top, and a drainage port is formed at the other end, and sealing covers 7 are threadedly connected at the water injection port and the drainage port.

[0025] In order to accurately and effectively adjust the compression amount of the conical spring 4, thereby accurately controlling the stability of the surfboard body 1, meeting the use requirements of different exercisers, and ensuring that the lacing part has sufficient strength to withstand tension, in the embodiment, as a preferred technical solution of the utility model, the lacing part of the buckle lacing 6 is an aramid fiber woven belt, which is uniformly distributed along the outer edges of the surfboard body 1 and the base 2, and each conical spring 4 corresponds to 1 or 2 groups of buckle lacing 6.

[0026] In order to significantly enhance the friction between the soles of the exercisers and the surfboard body 1, effectively avoid accidents caused by sole sliding during exercise, and comprehensively ensure the use safety of the exercisers, in the embodiment, as a preferred technical solution of the utility model, the top end face of the surfboard body 1 is pasted with a non-slip gasket 8, and the thickness of the non-slip gasket 8 is 3-5 mm.

[0027] In summary, by means of the above technical solutions of the utility model, when in use, first, the length of the buckle lacing 6 is adjusted, the compression amount of the conical spring 4 is changed according to the user's own conditions, and then the stability of the surfboard body 1 is adjusted. When it is necessary to improve the stability of the surfboard body 1, the buckle lacing 6 is tightened, the conical spring 4 is further compressed, the spring stiffness is increased, and the surfboard body 1 is relatively more stable; on the contrary, the buckle lacing 6 is loosened, the compression amount of the conical spring 4 is reduced, the stiffness is reduced, the shaking amplitude of the surfboard body 1 is relatively increased, and the instability of the simulated sea waves is more obvious. After adjusting the buckle lacing 6, the user can slowly stand on the surface of the surfboard body 1, and due to the instability of the conical spring 4, the center of gravity must be continuously adjusted to prevent falling off the surfboard body 1. The indoor surfboard simulates this shaking through a mechanical structure, forces the human body to repeatedly "oppose imbalance-recover balance" in a safe environment, so as to achieve the training purpose.

[0028] The positioning groove 3 opened at the top of the base 2 provides positioning for the installation of the conical spring 4. The small-diameter end of the conical spring 4 is connected to the bottom surface of the surfboard body 1 through the fixed support 5, and the large-diameter end is also connected to the groove bottom of the positioning groove 3 of the top surface of the base 2 through the fixed support 5. The fixed support 5 is fixedly connected with the surfboard body 1 and the base 2 through bolts, and this mechanical connection method has high stability and reliability, which can ensure that the connection between the conical spring 4 and the surfboard body 1 and the base 2 is stable during long-term use and dynamic stress.

[0029] As a key supporting component, the conical spring 4 plays a role by virtue of its unique structural characteristics. Unlike traditional cylindrical springs, the variable cross-section design of the conical spring 4 makes it have variable stiffness characteristics. When the exerciser steps on the surfboard body 1, the pressure exerted by him will be transmitted to the conical spring 4 through the fixed support 5. Since the large-diameter end of the conical spring 4 bears a larger area of force, the small-diameter end deforms elastically first at the initial stage of force, providing relatively soft cushioning; as the pressure increases, the large-diameter end also gradually participates in deformation, and the overall stiffness of the spring increases, providing stronger support force. This self-adaptive variable stiffness characteristic can adapt to the complex force of the surfboard and provide the exerciser with a more natural surfing experience.

[0030] The base 2 adopts a hollow water injection structure, and the weight of the base 2 can be increased by water injection, thereby improving the stability of the entire surfboard body 1. When water injection, an appropriate amount of water is injected from the water injection port, and the amount of water injection can be adjusted according to actual use requirements and the weight of the exerciser and other factors. After use, the water inside can be discharged through the drain port, facilitating transportation and storage. The water injection port and the drain port are both threadedly connected with sealing covers 7. This sealing connection can effectively prevent water leakage during use, ensure the stability of the water pressure inside the hollow structure of the base 2, and maintain the normal performance of the surfboard.

[0031] The anti-skid pad 8 is pasted on the top end face of the surfboard body 1, and has a thickness of 3-5mm. It is mainly used to increase the friction between the soles of the exerciser and the surfboard body 1, and prevent accidents caused by slipping of the soles during surfing. The anti-skid pad 8 is usually made of materials with high friction coefficient, such as EVA, and the surface texture design can further enhance the anti-skid effect, so that the exerciser can stably step on the surfboard body 1 when performing various actions, thereby improving the safety in use.

[0032] Finally, it should be pointed out that: in the present utility model, unless otherwise clearly specified and limited, the terms "installation", "setting", "connection", "fixing", "screw connection" and the like should be understood in a broad sense, for example, it can be fixed connection, or detachable connection, or integrated; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise clearly limited, the above-mentioned terms in the present utility model can be understood according to the specific meaning of the above-mentioned terms in the present utility model according to the specific situation.
