Abstract

A large-wheel-diameter oscillating and twisting type three-wheel slide plate comprises double front frames, a rear frame, pedal connection pieces, pedals, anti-abrasion bottom bars, wheel fork bearings, an oscillating and twisting mechanism, wheel forks with shafts, PU wheels and insert round covers. The double front frames are formed by welding two bent pipes and two rotating drums. The rear frame is formed by welding a rear bent pipe and a rotating drum. The pedal connection pieces are welded to the double front frames and the rear frame. The pedals are connected with the pedal connection pieces. The anti-abrasion bottom bars are connected with the pedals. The wheel fork bearings are embedded in the upper ends and the lower ends of the rotating drums. The oscillating and twisting mechanism is composed of spring steel, a polyurethane positioning sleeve, a plastic lining and a plastic sleeve. Each wheel fork with the shaft is formed by welding a metal wheel fork and a screw tube of a pair-locking bolt, the wheel forks with the shafts are connected to the wheel fork bearings, the PU wheels are connected with the wheel forks with the shafts, and flat-base bolts of the insert round covers are screwed into threaded holes of the screw tubes of the pair-locking bolts of the wheel forks with the shafts.

Description

[0001] Technical field:

[0002] The invention relates to an entertainment product, in particular to a large-diameter swinging and twisting three-wheeled skateboard with large-diameter front and rear wheels.

[0003] Background technique:

[0004] At present, it is difficult to find a large-diameter swinging and twisting three-wheeled skateboard that can move forward quickly by swinging the front and rear legs. At present, the front and rear wheels of the existing human-powered skateboards are generally about 3 inches, and the small-diameter skateboards slide When it is more sensitive to the impact on the ground, the requirements for the ground are relatively high, and there are relatively large limitations. The surfing skateboard I designed earlier, but because the front and rear of the skateboard frame is fixed, the surfing skateboard glides There is a certain degree of difficulty when sliding, and it is still more strenuous when swinging while sliding.

Embodiment Construction

[0017] according to figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 , the large wheel diameter swing and twist type three-wheeled skateboard includes double front frame 1, rear frame 2, pedal connecting piece 3, pedal 4, anti-wear bottom strip 5, wheel fork bearing, swing and twist mechanism 6, belt Shaft wheel fork 7, PU wheel 8 and insert dome cover 9;

[0018] The double front frame 1 includes two bending tubes and two rotating cylinders. The bending tube is bent upwards at the front of the round tube, and then curved forward in an arc shape. The bending tube The upward bending is to bend the round tube by punching. After the bent tube is bent, there is a depression similar to a countersunk hole on the inner corner side, and then in the depression after bending the bent tube Weld a reinforcement sheet, then bend the front direction of the upward bending position of the bending tube on the left side to the left, and bend the front direction of the upward bendi...
