[0032] like Figures 1-4As shown in the figure, as an embodiment of the present invention, a free gliding device is provided, including a gliding mechanism 1, a support mechanism 2, and a first connecting structure 4. The gliding mechanism 1 is configured as a sheet structure, and its top surface is configured as a gliding surface that can be used for gliding. The gliding surface can be made of gliding materials such as imitation ice surface to facilitate gliding. The gliding mechanism 1 includes a gliding area 13 configured as a long strip area, and a first end 11 and a second end 12 disposed at both ends of the gliding area 13. The first connecting structure 4 is disposed at the first end 11 along the width direction of the gliding mechanism 1. The support mechanism 2 is disposed on the side of the first connecting structure 4 away from the gliding mechanism 1. The support mechanism 2 includes a support pad 21 made of a soft material such as sponge, and an installation component 22 that partially or completely covers the support pad 21. The soft material support pad 21 can provide good cushioning when supporting the user. The installation component 22 is connected to the first connecting structure 4. The free-gliding equipment in this embodiment, by setting up a support mechanism 2, allows users to not only perform regular straight-line gliding on the gliding surface of the gliding area 13, but also to use the support pad 21 of the support mechanism 2 for soft support, kneeling on the support pad 21 and gliding prone to perform abdominal exercises with their hands, or placing their elbows on the support pad 21 and gliding prone to perform abdominal exercises with their feet, thus realizing gliding training in different postures, greatly enriching the gliding methods and meeting diverse gliding needs; in addition, the support pad 21 of the support mechanism 2 is connected to the first connecting structure 4 through the mounting component 22 that partially or completely covers the support pad 21, so that the support mechanism 2 and the first connecting structure As a whole structure, the first connecting structure 4 and the sliding mechanism 1 can enhance the stability of the first connecting structure 4 on the ground or other medium surface through the weight of the supporting mechanism 2 itself, making it less likely for the first connecting structure 4 and the sliding mechanism 1 to move relative to the ground or other medium surface. On the other hand, when the user slides in a prone position, the pressure applied to the supporting pad 21 by the user's hands or legs can further enhance the stability of the first connecting structure 4 on the ground or other medium surface, which can more effectively resist the impact and friction generated on the sliding mechanism 1 by the user's movement, prevent the sliding area 13 from moving relative to the ground or other medium surface, and improve the safety during use.

[0033] like Figure 1 As shown, in some specific embodiments, the dimension of the first connecting structure 4 along the length direction is greater than the width dimension of the first end 11 and completely covers the first end 11. The dimension of the first connecting structure 4 along the length direction is greater than the width dimension of the support pad 21 and completely covers the end of the mounting component 22, so as to protect the first end 11 and the end of the mounting component 22 from wear by external objects, thereby improving the stability of the connection between the first end 11 and the first connecting structure 4, and the stability of the connection between the end of the mounting component 22 and the first connecting structure 4.

[0034] like Figure 3 , Figure 4 As shown, in some specific embodiments, the first connecting structure 4 includes a first lower housing 41 and a first upper housing 42 detachably connected to the upper side of the first lower housing 41. The first lower housing 41 and the first upper housing 42 form a first chamber 40. A first channel 43 is formed between the first upper housing 42 and the first lower housing 41 along their length direction, allowing the first end 11 to extend into the first chamber 40. A second channel 44 is formed between the first upper housing 42 and the first lower housing 41 along their length direction, allowing the end of the mounting component 22 to extend into the first chamber 40. The first end 11 and the end of the mounting component 22 can be connected to the first connecting structure 4 respectively before assembling the first lower housing 41 and the first upper housing 42, with the first end 11 arranged in the first channel 43 and the end of the mounting component 22 arranged in the second channel 44. This facilitates quick assembly or disassembly of the first end 11 and the end of the mounting component 22 from the first connecting structure 4. Users can selectively install or disassemble the support mechanism 2 or the sliding mechanism 1 according to their needs, adapting to different usage requirements. Of course, in other embodiments, the first channel 43 or the second channel 44 can also be configured as a through hole structure that passes through the side wall of the first lower housing 41 or the first upper housing 42, and can also be used to extend the first end 11 or the end of the mounting component 22 into the first chamber 40 to avoid wear from foreign objects.

[0035] In some specific embodiments, the inner wall of the first lower housing 41 is provided with a plurality of first lower positioning posts 411 along the first channel 43 and a plurality of second lower positioning posts 412 along the second channel 44. The inner wall of the first upper housing 42 is provided with a plurality of first upper positioning posts 421 corresponding to the first lower positioning posts 411 and a plurality of second upper positioning posts 422 corresponding to the second lower positioning posts 412. The corresponding first upper positioning posts 421 and first lower positioning posts 411, and the second upper positioning posts 422 and second lower positioning posts 412 are detachably connected by fasteners such as screws and bolts. The first end 11 is provided with a plurality of first positioning holes 111 sleeved on the first lower positioning posts 411 or the first upper positioning posts 421 along the width direction. The end of the mounting component 22 is provided with a plurality of second positioning holes 2211 sleeved on the second lower positioning posts 412 or the second upper positioning posts 422 along the width direction. In this embodiment, the first lower positioning post 411 or the first upper positioning post 421 can serve as a connection structure for detachably connecting the first lower housing 41 and the first upper housing 42, and can also serve as a connection structure for connecting the first end 11 and the first connecting structure 4. The second lower positioning post 412 or the second upper positioning post 422 can serve as a connection structure for detachably connecting the first lower housing 41 and the first upper housing 42, and can also serve as a connection structure for connecting the end of the mounting component 22 and the first connecting structure 4, thus achieving the effect of multiple uses in one device.

[0036] like Figure 4 As shown, in some specific embodiments, the bottom wall of the first lower housing 41 is provided with a plurality of fastening holes 413 corresponding to the first lower positioning posts 411 and the second lower positioning posts 412, for fasteners such as screws and bolts to pass through. Fasteners can be connected to the corresponding first lower positioning posts 411 and first upper positioning posts 421 via the fastening holes 413, or connected to the corresponding second lower positioning posts 412 and second upper positioning posts 422, facilitating assembly or disassembly. The lower side of the first lower housing 41 is connected to a support plate 46 for mounting on a surface such as the ground. The support plate 46 can be made of soft silicone or EVA pads, providing a certain anti-slip effect, allowing the first connecting structure 4 to be placed more stably on the surface. As another embodiment of this utility model, a plurality of feet can also be connected to the lower side of the first lower housing 41, allowing the first connecting structure 4 to be mounted on a surface such as the ground. Optionally, these feet can be suction cups for stable adhesion to the surface, or ordinary feet.

[0037] like Figure 3 As shown, in some specific embodiments, the mounting component 22 includes an upper mounting surface 221 arranged on the upper side of the support pad 21, a lower mounting surface 222 arranged on the lower side of the support pad 21, and a side mounting surface 223 arranged around the support pad 21. The side mounting surface 223 connects the upper mounting surface 221 and the lower mounting surface 222, so that the upper, lower, and peripheral sides of the support pad 21 are all wrapped within the mounting component 22 and stably connected to the mounting component 22, making it less likely to detach from the mounting component 22. One end of the upper mounting surface 221 protrudes from the side of the support pad 21 and is connected to the first connecting structure 4 through a second positioning hole 2211 provided on the upper mounting surface 221. The mounting component 22 can be made of materials such as textile fabric or leather fabric, which has a certain degree of softness to ensure the comfort of the user supporting the support pad 21.

[0038] like Figure 4As shown, in some specific embodiments, the upper side of the support pad 21 is completely covered by the upper mounting surface 221, the lower side of the support pad 21 is completely covered by the lower mounting surface 222, and the side of the support pad 21 away from the sliding mechanism 1 is completely covered by the side mounting surface 223. This securely wraps the support pad 21 within the mounting component 22, preventing the support pad 21 from moving away from the sliding mechanism 1 and detaching from the mounting component 22 during user movement. Furthermore, the two sides of the support pad 21 arranged along the width direction of the sliding mechanism 1 are also completely covered by the side mounting surface 223, making the support pad 21 almost completely enclosed within the mounting component 22. This improves the stability of the connection with the mounting component 22 and protects the support pad 21 from wear. In other embodiments, the upper mounting surface 221, lower mounting surface 222, or side mounting surface 223 of the mounting component 22 may also have a hollow structure, allowing the mounting component 22 to partially enclose the support pad 21.

[0039] like Figure 1 As shown, in some specific embodiments, a second connecting structure 5 is further provided at the second end 12 along the width direction of the sliding mechanism 1. The top of the first connecting structure 4 protrudes from the sliding surface, so that a first partition portion is formed on the side wall of the first connecting structure 4 near the second connecting structure 5 to block one end of the sliding area 13, preventing the user from sliding excessively towards the first end 11 and falling. The top of the second connecting structure 5 protrudes from the sliding surface, so that a second partition portion is formed on the side wall of the second connecting structure 5 near the first connecting structure 4 to block the other end of the sliding area 13, preventing the user from sliding excessively towards the second end 12 and falling.

[0040] In some specific embodiments, the sliding mechanism 1 is made of a flexible material that can be rolled up along its length, allowing it to be rolled up and stored. The bottom surface of the sliding mechanism 1 is configured as a placement surface that can be placed on a medium surface such as the ground. The placement surface can be made of a non-slip material such as rubber, which can stably conform to the medium surface and is not easily moved relative to the medium surface. In use, it can be placed on a medium surface such as the ground through the support mechanism 2, the first connecting structure 4, the second connecting structure 5, and the placement surface of the sliding area 13. The placement is stable and not easily moved relative to the medium surface.

[0041] like Figure 5As shown, in some specific embodiments, a sliding plate 31 is also included, which is placed on the sliding surface of the sliding area 13. The sliding plate 31 includes a skateboard body 311 for supporting the user and a sliding part 313 protruding from the bottom of the skateboard body 311. The user can slide along the sliding surface of the sliding area 13 by placing body parts such as elbows or feet on the sliding plate 31. Compared with placing body parts such as elbows or feet directly on the sliding surface of the sliding area 13, the sliding is smoother. The sliding part 313 is integrally formed with the skateboard body 311, resulting in a simple structure. It can slide along the sliding surface of the sliding area 13. In this embodiment, the sliding part 313 is an arc-shaped slider that protrudes downward from the bottom of the skateboard body 311, thereby reducing the contact area between the sliding plate 31 and the sliding surface of the sliding area 13. This facilitates easy sliding of the sliding plate 31 along the sliding surface of the sliding area 13 by the user. Furthermore, the arc-shaped slider is arranged along the length of the sliding area 13, allowing sliding by contacting the sliding area 13 at different positions. This adapts to different force angles applied by the user during the back-and-forth movement of the sliding plate 31 along the length of the sliding area 13, making the abdominal exercise more in line with human anatomy. Two sliding parts 313 are arranged side by side, allowing the sliding plate 31 to be stably placed on the upper side of the sliding area 13 without easily deflecting or wobbling along the width of the sliding area 13. In other embodiments, more sliding parts 313 may be provided. In this embodiment, two sliding plates 31 are provided, and the two sliding plates 31 can slide independently along the sliding area 13, which is suitable for more postures of sliding abdominal exercises. In other embodiments, only one sliding plate 31 or other quantities may be provided.

[0042] like Figure 6 As shown, in some specific embodiments, the skateboard body 311 is connected to a handle 312, which facilitates the user to hold the slide board 31 and slide along the sliding area 13. In other embodiments, a foot kit suitable for wearing on the user's feet can also be connected to the skateboard body 311, which facilitates the user's feet to be stably placed on the slide board 31 and slide along the sliding area 13.

[0043] like Figure 5 As shown, in some specific embodiments, the sliding plate 31 is connected to the first connecting structure 4 via a connecting unit 32. The connecting unit 32 is configured as an elastic rope, elastic band, spring, or other elastic structure, which can provide elastic resistance when the user supports the sliding plate 31 as it slides along the sliding surface of the sliding area 13 toward the second end 12, thereby enhancing the intensity of the abdominal exercise. The connecting unit 32 and the first connecting structure 4 can be configured as a detachable connection, allowing the user to selectively install or remove the connecting unit 32 according to usage needs, or they can be configured as a fixed connection to improve the stability of the connection with the first connecting structure 4.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.

[0045] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
