Problems solved by technology

[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 more strenuous when swinging while sliding

Embodiment Construction

[0018] according to figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 , the large wheel diameter swing and twist foldable three-wheeled skateboard includes double front frame 1, rear frame 2, pedal connector 3, swing and twist folding mechanism 4, pedal 5, anti-wear bottom strip 6, wheel fork bearing , wheel fork with shaft 7, PU wheel 8 and insert dome cover 9;

[0019] The double front frame 1 includes two bent pipes, a rear round pipe and two rotating cylinders, the bent pipe is bent upwards at the front of the round pipe, and then curved forward in a circular arc shape. The upward bending of the bent tube is done by punching the round tube in an angled way. After the bent tube is bent, there is a depression similar to a countersunk hole on the side of the inner corner, and then the bent tube is bent Weld a reinforcement sheet to the bent depression, then bend the front direction of the upward bending position of the bending tube on the left side to the left, a...
