Large wheel diameter swing twist folding three-wheel skateboard

Abstract

A large-wheel-diameter swinging, twisting and folding type three-wheel skateboard comprises a double front frame, a back frame, pedal connecting parts, a swinging, twisting and folding mechanism, pedals, abrasionproof bottom strips, wheel fork bearings, wheel forks with shafts, PU wheels and circular insert covers. The double front frame is formed by welding two bent pipes, a back circular pipe and two rotating drums; the back frame is formed by welding a back bent pipe and a rotating drum; the pedal connecting parts are welded to the double front frame and the back frame; the swinging, twisting and folding mechanism is formed by connecting locking bushes, lock pin locating rings, nylon linings, a swinging and twisting structure, lock pins, springs and stepped bolts, and the two ends of the swinging, twisting and folding mechanism are connected with the double front frame and the back frame; the pedals are connected with the pedal connecting parts and the abrasionproof bottom strips; the wheel fork bearings are inlaid into the rotating drums; the wheel forks with the shafts are connected with the wheel fork bearings and the PU wheels; the circular insert covers are connected to the tops of screwed drums of locking bolts of the wheel forks with the shafts in a screwed mode.

Description

[0001] Technical field: [0002] The invention relates to an entertainment product, in particular to a large-diameter swing, twist, and foldable three-wheel skateboard with large-diameter front and rear wheels. [0003] Background technique: [0004] At present, it is difficult to find a large-diameter swing, twist, and foldable three-wheeled skateboard that can move forward quickly by swinging the front and rear feet. Currently, the front and rear wheels of the existing human-powered skateboards are generally about 3 inches, and the small-diameter skateboards When skating, it is more sensitive to the influence of the ground, and the requirements for the ground are relatively high, and there are relatively large limitations. The surfing skateboard I designed earlier, but because of the fixed structure of the front and rear of the skateboard skeleton, the surfing skateboard There is a certain degree of difficulty when sliding, and it is still relatively strenuous when swinging w...
