Description

Technical Field

[0001] This invention relates to the field of sandboard technology, specifically to a sandboard with protective functions. Background Technology

[0002] As we all know, sandboarding is the act of riding a skateboard down a high sand dune. The skateboards are made of materials such as wood, bamboo, and plastic. When people are sandboarding, the skateboards may collide due to unpredictable factors, which may lead to situations such as tipping over.

[0003] A search revealed that a sandboard, patent publication number CN112827157A, was published in China on May 25, 2021. The general description includes a skateboard body with handrails on both sides, a baffle in the middle, hooks A on the baffle, hooks B on the inner wall of the rear half of the skateboard body, nets on hooks A and B, a U-shaped opening on the backrest, a pivot and a torsion spring groove on the two vertical surfaces of the U-shaped opening, a brake backrest and a torsion spring on the pivot, a groove at the hinge of the brake backrest, one end of the torsion spring in the torsion spring groove, and the other end in the groove. The bottom of the skateboard body has wear-resistant strips and guide strips.

[0004] Although the existing technical solutions described above use PE boards for the guide plate and wear-resistant plate, which increases the wear resistance of the sandboard and extends its service life, they are not easy to dampen during the sandboard's sliding process. At the same time, they are not easy to prevent the sandboard from tipping over, resulting in low safety. Summary of the Invention

[0030] Please see Figure 1-6A protective sandboard includes a sandboard body 1. Fixing plates 2 are fixedly connected to both the front and rear ends of the sandboard body 1, securing the fixing plates 2. Two fixing blocks 3 are fixedly connected to the bottom ends of each fixing plate 2, securing the two fixing blocks 3. Rotating grooves are provided on the two fixing blocks 3, and connecting shafts are rotatably connected within these grooves. Support plates 4 are provided on the two fixing blocks 3, allowing the connecting shafts to rotate. Support plates 4 are fixedly connected to the connecting shafts, securing the support plates 4. Two mounting brackets 5 are fixedly connected to each of the two support plates 4, securing the two mounting brackets 5. The bottom ends of the two fixing plates 2 are fixedly connected to... Two circular sleeves 6 are fixed to each other by two fixing plates 2. Each circular sleeve 6 has a telescopic rod 7 slidably connected inside it, allowing the telescopic rods 7 to slide. The two telescopic rods 7 are rotatably connected to two mounting brackets 5, allowing the two mounting brackets 5 to rotate. Two first fixing rings 8 are fixedly connected to each of the two support plates 4, securing the two first fixing rings 8. A first spring 9 is fixedly connected to each of the two first fixing rings 8, securing the first spring 9. A second fixing ring 10 is fixedly connected to the end of the first spring 9 furthest from the first fixing ring 8, securing the second spring 10. The fixed ring 10 is fixedly connected to the sandboard body 1, and the second fixed ring 10 is fixed by the sandboard body 1. Through the cooperation of components such as the support plate 4, the circular sleeve 6, and the telescopic rod 7, the sandboard body 1 can maintain better stability during sliding. In the event of a rollover, the support plate 4 can limit the roll, allowing it to be reset by components such as the first spring 9, ensuring personal safety. A first connecting plate 11 is fixedly connected to the bottom left side of the sandboard body 1. A separation plate 12 is fixedly connected to the first connecting plate 11. Multiple separation grooves are formed on the separation plate 12, and multiple isolation plates 13 of different sizes are sequentially installed in the multiple separation grooves. A second connecting plate 14 is fixedly connected to the bottom right side of the sandboard body 1. Two mounting blocks 15 are fixedly connected to the 14. Each mounting block 15 has a connecting groove at one end facing the other. A connecting rod is rotatably connected to the two connecting grooves. A shock-absorbing plate 16 is fixedly connected to the connecting rod. Two support columns 17 are fixedly connected to the top of the shock-absorbing plate 16. A connecting block 18 is slidably connected to the top of each support column 17. The connecting block 18 is fixedly connected to the sand-sliding plate body 1. A sliding groove is provided on the sand-sliding plate body 1. The support column 17 passes through the connecting block 18 and is slidably connected to the sliding groove. A second spring 19 is installed on the support column 17. Through the arrangement of components such as the shock-absorbing plate 16, the second spring 19, and the support column 17, the impact on the sand-sliding plate when encountering bumps or other problems during sliding can be reduced.

[0031] It should also be noted that a mounting plate 20 is fixedly connected to the sandboard body 1, and a telescopic sleeve 21 is fixedly connected to the bottom end of the mounting plate 20. The telescopic sleeve 21 is fixedly connected to the sandboard body 1. A moving rod 22 is slidably connected inside the telescopic rod 7. The moving rod 22 passes through the mounting plate 20 and the sandboard body 1. A steering wheel is fixedly connected to the top end of the moving rod 22, and a steering plate is fixedly connected to the bottom end of the moving rod 22. Two first sliding plates 23 and two second sliding plates 24 are fixedly connected to the sandboard body 1. Sliding grooves are provided at the opposite ends of the two first sliding plates 23 and the opposite ends of the two second sliding plates 24. Sliding blocks are slidably connected in the multiple sliding grooves. Positioning plates 25 are fixedly connected to the sliding blocks. Each of the positioning plates 25 has a sliding rod 26 fixedly connected to its bottom end, and a brake plate 27 fixedly connected to its bottom end. The brake plate 27 passes through the sand-sliding plate body 1. Each of the two positioning plates 25 has a positioning block fixedly connected to its opposite end, and a foot brake 28 fixedly connected to its opposite end. Each of the two positioning plates 25 has a third spring 29 fixedly connected to its bottom end, and a limit plate fixedly connected to its bottom end. The limit plate is fixedly connected to the first sliding plate 23 and the second sliding plate 24, and is slidably connected to the sliding rod 26. Through the arrangement of components such as the first sliding plate 23, the second sliding plate 24, and the brake plate 27, the sand-sliding plate body 1 can be easily braked suddenly when encountering unexpected phenomena during the sliding process.

[0032] In summary, the installation process of this protective sand-slipper is as follows: First, the sand-slipper body 1 fixes the fixing plate 2. The two fixing plates 2 then fix the two fixing blocks 3. Support plates 4 are provided on the two fixing blocks 3, allowing the connecting shaft to rotate. The connecting shaft fixes the support plates 4. The two support plates 4 fix the two mounting brackets 5. The two fixing plates 2 fix the two circular sleeves 6. The two circular sleeves 6 allow the telescopic rods 7 to slide. The two telescopic rods 7 allow the two mounting brackets 5 to rotate. The two support plates 4 fix the two first fixing rings 8. The two first fixing rings 8 fix the first spring 9. The first spring 9 fixes the second spring 19. (The text abruptly ends here, likely due to an incomplete sentence or missing information.) The main body 1 is fixed to the second fixing ring 10. Through the cooperation of components such as the support plate 4, the circular sleeve 6 and the telescopic rod 7, the main body 1 of the sandboard can maintain better stability during the sliding process. At the same time, in the event of a rollover, the support plate 4 can limit the movement and reset it through components such as the first spring 9, ensuring personal safety. The shock-absorbing plate 16, the second spring 19 and the support column 17 can reduce the impact of the sandboard when encountering bumps during the sliding process. The first sliding plate 23, the second sliding plate 24 and the brake plate 27 can facilitate emergency braking of the main body 1 of the sandboard in the event of a sudden event during the sliding process.
