Iron art modeling double-folding type three-wheeled dynamic skateboard made of metal round bars

Abstract

The invention discloses an iron art modeling double-folding type three-wheeled dynamic skateboard made of metal round bars. The dynamic skateboard comprises an iron art modeling front pedal, an iron art modeling rear pedal, three spiral tubes, three spiral tube blank caps, two rotating tubes, a connecting rod and three universal wheels, wherein both the iron art modeling front pedal and the iron art modeling rear pedal are formed by bending and welding the metal round bars; two spiral tubes are welded at the two front ends of the iron art modeling front pedal while the other screw tube is welded at the front end of the iron art modeling rear pedal; metal pipe rings of the two rotating tubes are welded at the rear end of the iron art modeling front pedal and the front end of the iron art modeling rear pedal; plastic lining members of the two rotating tubes are pressed into metal pipes of the two rotating tubes; four rotating tube bearings are pressed into the plastic lining members of the two rotating tubes; the right-angle bending parts of the connecting rod penetrate into inner holes of rotating tube bearings in the two rotating tubes and are positioned by screwing two bolts into the threaded holes in the two ends of the connecting rod; the three universal wheels are connected into the two spiral tubes at the two front ends of the iron art modeling front pedal and the spiral tube at the front end of the iron art modeling rear pedal respectively.

Description

Technical field: [0001] The present invention relates to an entertainment product, in particular to a double-folding three-wheel dynamic skateboard made of metal round rod material and wrought iron shape, which uses cross twisting of front and back feet or cross swing to both sides to move forward. Background technique: [0002] At present, there is a dynamic board on the market that uses the front and back feet to move forward, and it is relatively popular; but it has certain limitations and regrets, because there is a plastic board at each end, and a universal board at the bottom of the plastic board. There is a round tube-shaped connecting rod that can be twisted between the two plastic plates, and a torsion spring is connected to the round tube-shaped connecting rod. Because there is a connecting rod structure with a torsion spring in the tube between the two plastic plates, it must be Most types of active boards cannot be folded, resulting in unsatisfactory portability;...

[0002] At present, there is a dynamic board on the market that uses the front and back feet to move forward, and it is relatively popular; but it has certain limitations and regrets, because there is a plastic board at each end, and a universal board at the bottom of the plastic board. There is a round tube-shaped connecting rod that can be twisted between the two plastic plates, and a torsion spring is connected to the round tube-shaped connecting rod. Because there is a connecting rod structure with a torsion spring in the tube between the two plastic plates, it must be Most types of active boards cannot be folded, resulting in unsatisfactory portability; because the middle part of the active board is a twisting structure, the displacement of the twenty universal wheels of the active board is relatively small, resulting in unsatisfactory riding speed of the active board ;Because there are universal wheels on the front and back of the vitality board, it is relatively difficult to learn to use it
