Description

Technical Field

[0001] The utility model belongs to the technical field of skateboard design, in particular to a roto-molded skateboard. Background Art

[0002] Sandboarding, also known as dune boarding, is an outdoor sport in desert areas. Participants can sit on a special sandboard and slide and land on sand dunes or deserts by pushing or adjusting their weight, which brings participants a strong sense of excitement and challenge. Speeding, diving, and then shuttling through the sand in the vast desert, fully releasing the desire for speed and freedom. Sandboarding is not only a sports challenge, but also an experience of getting close to and communicating with nature, allowing people to respect and cherish the beauty and wonder of nature more. In general, sandboarding is an exciting and interesting outdoor activity suitable for those who like challenges and adventures. By participating in sandboarding, you can experience the unique fun and excitement in the desert and feel the infinite charm and magic brought by nature.

[0003] A sandboard is a device designed for gliding in the desert or on sand. It is usually a specially made sandboard with a smooth surface that can be used to glide and slide down sand dunes. This type of board is usually wider than a normal skateboard and has a flatter bottom to provide a better sliding experience on the sand. Sandboards are usually made of wear-resistant and heat-resistant materials to ensure good durability and stability in sandy environments. The bottom of the board is usually designed as a smooth metal plate or coating to help reduce friction and make gliding smoother. In addition, the size and weight of the sandboard will be adjusted to suit the special conditions and requirements of the sand.

[0004] In the integrated rotational molding manufacturing process of existing skateboards, the backrest size cannot be too high, otherwise the rotational molding process will have certain processing difficulties, and the low backrest is difficult to provide effective support, and the user's back is prone to discomfort; the bottom of the existing skateboard is a smooth arc, which is easy to deviate left and right during the sliding process, and in severe cases may cause the skateboard to tip over, affecting the safety of the user.

[0008] Furthermore: a backrest is provided at the rear of the skateboard body.

[0009] Furthermore: the backrest includes a support frame, a backrest cushion is arranged on the top of the support frame, and the bottom of the support frame is installed on the lumbar support.

[0010] Furthermore: the backrest cushion is provided with a plurality of ventilation holes.

[0011] Furthermore: two fixing holes are symmetrically arranged on the waist support, the support frame is in an inverted U-shape, and both ends of the support frame are installed in the fixing holes.

[0012] Furthermore: the support frame and the lumbar support are connected by bolts.

[0013] Furthermore: a traction hole is arranged in front of the handrail.

[0014] Furthermore: a plurality of guide strips are evenly arranged on the bottom of the chassis.

[0015] Furthermore: the lumbar support is in a step-shaped shape.

[0016] Furthermore: the footrest is an isosceles trapezoid.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. The main body of the skateboard is processed by integral rotational molding. The support frame on the backrest is inserted into the fixing hole on the waist support, and then the bolts are screwed into the bottom of the support frame to complete the installation of the backrest. The design of independent installation of the backrest avoids excessive protrusions on the main body of the skateboard, reducing the difficulty of rotational molding;

[0019] 2. The rider sits on the skateboard and slides down the sand dune. During the sliding process, the guide strips arranged parallel to the bottom of the chassis play a limiting role, preventing the skateboard from turning left and right, keeping the sliding trajectory straight, avoiding the skateboard from tilting and causing overturning, and improving the safety of the device;

[0020] 3. The staff drags the rope in the towing hole and pulls the handle to drive the skateboard back to a higher place. By setting the towing hole and the handle, the handle and the rope provide force points for pulling the skateboard, which makes it easier to move the skateboard with a large overall arc and difficult to apply force by hand, thereby improving the convenience of recovering the skateboard and facilitating long-term use.
