Abstract: 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.

Abstract: An assembled chair includes a chair seat, a chair back, two connectors, two fixing sleeves and two protection cases. The two connectors respectively have two connection portions. The two fixing sleeves are respectively arranged at two opposite sides of the chair back. The two protection cases are respectively fixed at two opposite sides of the chair seat, and the two connectors are respectively arranged in the two protection cases, and the two connection portions emerges from the two protection cases, and the two fixing sleeves respectively sleeve the two connection portions, and at least two fixing members are respectively fixed to the two connection portions, so as to fix the chair back to the chair seat.
