Embodiment 1

[0015] Such as Figure 1-3 As shown, a hand-pulled skateboard proposed by the present invention includes a skateboard body and a power assembly; the skateboard body includes a skateboard surface 3, a wheel shaft 58 and a skateboard wheel 6; the power assembly includes a pull ring 1, a pull cord 2, and a fixed pulley 4 , power box 5, upper casing 51, winding barrel 52, coil spring 53, one-way bearing 54, power shaft 55, driving gear 56, driven gear 59 and lower casing 510;

[0016] The bottom of the skateboard surface 3 is provided with a mounting seat, and the skateboard wheels 6 are rotated and arranged on the mounting seat. The skateboard wheels 6 are set in two groups, each group includes two skateboard wheels 6, and the two skateboard wheels 6 of each group pass through the wheel shaft. 58 connection, the skateboard surface 3 is provided with a through hole for the stay rope 2 to pass through;

[0017] The fixed pulley 4 is arranged at the bottom of the skateboard surface...

Embodiment 2

[0020] Compared with Embodiment 1, the hand-pull skateboard proposed by the present invention has two groups of power components, and the two groups of power components are respectively located at the front and rear ends of the skateboard surface 3 .

[0021] In this embodiment, the pull rope 2 adopts double ropes, one in front and one in the back, and it is more stable and safe for people to stand on the skateboard surface 3. Compared with traditional skateboards, the center of gravity of people can be better stabilized, ensuring safety. got improved.

Embodiment 3

[0023] Compared with the first embodiment, the hand-pull skateboard proposed by the present invention has two sets of coil springs 53 , and the two sets of coil springs 53 are symmetrical about the winding barrel 52 .

[0024] In this embodiment, by setting two sets of coil springs 53, the winding barrel 52 can be rotated quickly, so that the pull cord 2 can be retracted quickly, which is convenient for pulling next time.

Abstract

The invention relates to the technical field of skateboards, in particular to a hand-pulling type skateboard. The hand-pulling type skateboard comprises a skateboard body and a power assembly, wherein a front group and a rear group of skateboard wheels are arranged, each group of skateboard wheels comprises two skateboard wheels, and the two skateboard wheels in each group are connected through a wheel shaft; a fixed pulley is arranged at the bottom of a skateboard surface; the bottoms of pull ropes bypass the fixed pulley, extend into a power box and are wound on a winding barrel; pull rings are arranged at the tops of the pull ropes; a power shaft is rotationally arranged on the inner wall of an upper box body; a one-way bearing is arranged on the power shaft; the winding barrel is arranged on a one-way bearing; a coil spring sleeves the power shaft; a driving gear is arranged on the power shaft; and a driven gear is arranged on the wheel shaft and meshed with the driving gear. According to the skateboard, power can be provided by pulling the pull ropes, and the skateboard can move forwards when a person stands on the skateboard, so more labor is saved; and the double pull ropes, namely one front pull rope and one rear pull rope, so people can stand on the surface of the skateboard more stably and safely.

Description

technical field [0001] The invention relates to the technical field of skateboards, in particular to a hand-drawn skateboard. Background technique [0002] As a sport, skateboarding has always been loved by many young people, but there are not many people who are good at skateboarding, because the existing skateboard structure requires participants to have good balance and strong physical fitness, and the existing skateboards are not stable enough , it needs pedals to actively control the balance, the principle is complex, the balance is insufficient, and the power source is single, the production is relatively complicated, and the cost is high. Contents of the invention [0003] The object of the present invention is to propose a hand-drawn skateboard to address the problems of insufficient stability of the skateboard in the background art, the need for pedals to provide power, and high production costs. [0004] The invention proposes a hand-drawn skateboard, which incl...
