[0022] Combined with appendix Figures 1-4 A back protection device for lower back training, comprising a back protection component and a head protection component.

[0023] The back protection component includes a central protection section and retractable extended protection sections on both sides of the central protection section. The extended protection sections are equipped with binding units for fixing the back protection component to the user's back. The head protection component includes an adjustable connecting section on the central protection section and a headrest section at the end of the connecting section.

[0024] In one embodiment of this utility model, such as Figures 1-4As shown, the intermediate protective part includes a back support plate 1. A protective pad 6 is provided on the side of the back support plate 1 away from the side that contacts the human body. The back support plate 1 has slots 15 extending to both sides, slot 2 extending to its top surface, and a through groove 14 connecting the slots to its bottom surface. Specifically, the back support plate 1 is rectangular and can be made of plastic or composite material with a certain strength and rigidity. The side of the back support plate 1 facing the back of the human body is kept flat or slightly curved to conform to the spine to increase comfort. Preferably, the protective pad 6 is made of high-density foam, which acts as a buffer component when the user leans back and contacts the ground to absorb impact.

[0025] In one embodiment of this utility model, such as Figures 1-2 As shown, the extended protective unit includes an extension plate 2, on which a plug-in plate 12 is provided to engage with a slot 15. A fixing bolt 13 is threaded onto the plug-in plate 12 and passes through a slot 14. A protective pad 6 is provided on the side of the extension plate 2 away from the human body. Specifically, the extension plate 2 is also rectangular in shape, with its long side being the same length as the short side of the back support plate 1. The plug-in plate 12 can be slidably inserted into the slot 15 of the back support plate 1. By pushing and pulling the extension plate 2, the plug-in plate 12 can slide within the slot 15. When the fixing bolt 13 is tightened, the bolt head presses against the inner wall of the slot 14, and the plug-in plate 12 is firmly locked together with the back support plate 1 through friction. This allows adjustment of the overall width of the entire back protection assembly to accommodate different users' shoulder widths and body shapes. A protective pad 6 is also provided on the side of the extension plate 2 away from the human body to ensure consistent cushioning performance across the entire back of the device.

[0026] In one embodiment of this utility model, such as Figure 1 As shown, the binding unit includes strap 3 and strap 4 fixedly mounted on the extension plate 2. Straps 3 on both sides are provided with Velcro for fastening, and straps 4 on both sides are provided with corresponding buckles 5. Specifically, there are two straps 3, each with a hook or loop side of Velcro at its free end. When the device is worn on the back, the straps 3 on both sides can be wrapped around the armpits to the chest and fastened. The Velcro fastening is used to support the main suspension weight. There are also two straps 4, which overlap with strap 3 in the height direction. The ends of straps 4 on both sides are provided with male and female buckles 5. When wearing the device, straps 4 can be wrapped around the armpits to the chest, and the male and female buckles can be inserted and locked together to secure the device to the body and prevent it from shaking or shifting during training.

[0027] In one embodiment of this utility model, such as Figure 3As shown, the connecting part includes an adjusting plate 7 that is slidably disposed in slot two, and an elastic connecting band 8 is provided at the top of the adjusting plate 7. Specifically, the connecting part is used to connect the head protection component and the middle protection component, and allows the height of the headrest to be adjusted. The adjusting plate 7 can be pulled up and down in slot two to change its extension length. Preferably, the elastic connecting band 8 can be made of elastic band, providing a certain degree of freedom and maintaining the integral structure of the product.

[0028] In one embodiment of this utility model, the adjusting plate 7 and the slot 2 are in a static friction fit. Specifically, there is an appropriate interference fit between the thickness of the adjusting plate 7 and the width of the slot 2, thereby generating sufficient static friction. Under normal circumstances, the adjusting plate 7 can stay at any height position in the slot 2 without slipping off by itself. When adjustment is required, the user only needs to apply a certain external force to push the adjusting plate 7 to slide. This stepless adjustment method is simple and reliable, and does not require an additional locking mechanism.

[0029] In one embodiment of this utility model, such as Figure 1 As shown, the headrest includes a head-fixing plate 9. The head-fixing plate 9 has straps 10 on both sides with Velcro fasteners. A U-shaped head-limiting pad 11 is located on the side of the headrest that contacts the body, while a protective pad 6 is located on the side away from the body. Specifically, in use, the head can be placed on the headrest, and the straps 10 can be wrapped around the forehead and secured with Velcro to prevent the head from sliding left and right on the headrest, ensuring adequate protection. Furthermore, the U-shaped head-limiting pad 11 is typically made of memory foam; its U-shaped indentation can accommodate and limit the back of the user's head, providing a comfortable wrapping feel and lateral support for the neck. The protective pad 6 on the headrest 9 ensures that the headrest also provides cushioning when it hits the ground.

[0030] A lower back training protection device according to an embodiment of the present invention.

[0031] When in use, first adjust according to the user's body shape, loosen the two fixing bolts 13, pull the two extension plates 2 outward until their total width is slightly narrower than the user's shoulders, then tighten the fixing bolts 13 to lock the position of the extension plates 2. Next, according to the user's height and habits, pull up or press down the adjustment plate 7 of the connecting part to initially set the approximate height of the headrest.

[0032] Then, the user places the device against their back, wraps the two straps 1 3 around their armpits to their chest and secures them, then wraps the two straps 2 4 around their armpits to their chest and fastens them with buckles 5. After that, the user adjusts the position of the headrest and secures it comfortably to their head with straps 3 10.

[0033] When a user begins backbend training, the back protection device follows the user's back movement. In the event of a fall, it can effectively protect the cervical spine and head from impact injuries, allowing the user to practice independently and safely.

[0034] The present invention and its embodiments have been described above. This description is not restrictive, and the embodiments shown throughout the text are only one of the embodiments of the present invention. The actual structure is not limited to this. In conclusion, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
