Abstract: A riveting structure of a caster wheel contains: a connecting mount, a wheel seat, and a coupling shaft. The connecting mount includes a central hole longitudinally defined at a central position thereof The wheel seat includes a horizontal orifice, a central groove, and an accommodating slot horizontally defined on a distal end of the central groove and communicating with the central groove to accommodate a peripheral rib extending around a distal end of a lower extension of the coupling shaft. The lower extension is inserted into the central groove so that the peripheral rib is retained in the accommodating slot of the wheel seat, an upper extension of the coupling shaft is inserted through the central hole of the connecting mount so that a top end of the upper extension of the coupling shaft is riveted in the connecting mount, thus connecting the connecting mount and the wheel seat together.

Abstract: A quick release structure for front wheels of baby strollers includes an upper mount disposed on one leg support thereof. A fixing pin is arranged on the upper mount for inserting into a locking hole on the leg support. Moreover, a lower mount assembled with a wheel is set on the bottom of the upper mount. A connection rod at the top of the lower mount is inserted into the upper mount. A fixing groove for locking with the fixing pin is formed around the side wall close to the top of the connection rod. A positioning slot is provided on the bottom of the upper mount for mounting a L-shaped positioning rod pivoted on the lower mount. Thus the stroller can keep moving forward without changes in directions by pressing the positioning rod to be locked into the positioning slot for the purposes of easy assembling, storage and transportation.

Abstract: A wheel assembly includes a main body, two wheels, two positioning shafts, and two retaining rods. In practice, the retaining portion of each of the retaining rods is urged on the positioning plates of the respective positioning shaft to position the locking portion of each of the positioning plates on the inner side the respective pivot hole of the main body so as to lock each of the two positioning shafts on the main body, so that each of the two wheels is attached on the main body rigidly and stably, thereby preventing the two wheels from detaching from the main body during a long-term utilization.

Abstract translation: 轮组件包括主体，两个轮，两个定位轴和两个固定杆。 实际上，每个保持杆的保持部分被推压在相应定位轴的定位板上，以将每个定位板的锁定部分定位在主体的相应枢轴孔的内侧，以便锁定 主体上的两个定位轴中的每一个，使得两个车轮中的每一个刚性且稳定地附接在主体上，从而防止两个车轮在长期使用期间与主体分离。
