Patent attributes
A pressured braking wheel includes a wheel seat, an axle sleeve, a first wheel rim and a second wheel rim. The wheel seat has an accommodation space and a braking tenon. The axle sleeve is arranged in the accommodation space and sleeves a wheel axle. Inner sides of the first wheel rim and the second wheel rim are respectively annularly provided with first tenon grooves and second tenon grooves. The first wheel rim and the second wheel rim pivotally connect with the axle sleeve through the wheel axle. The first tenon groove and the second tenon groove are arranged under the braking tenon. When the wheel seat is pressed down, the wheel seat inserts the braking tenon into the first tenon groove and the second tenon groove, so as to prevent the first wheel rim and the second wheel rim from rotating with respect to the wheel seat.
