As shown in fig. 1, a partial schematic view of a stroller 1 according to the present invention includes a pair of front legs 10 and a pair of wheel sets 20 mounted on the front legs 10, wherein the wheel sets 20 are pivotally connected to the front legs 10 by a wheel fixing device 30 and can rotate in a universal direction. Preferably, both side wheel sets 20 include two wheels 20a, 20b, but are not so limited.
As shown in fig. 2 and 3, the wheel securing device 30 includes a wheel mounting seat 31, a wheel strut 32, and a rotating mechanism 33. One end of the wheel mounting seat 31 is pivotally connected to the wheels 20a and 20b, and the other end of the wheel mounting seat 31 is pivotally connected to the wheel strut 32 via the rotating mechanism 33. As a concept of the present invention, the wheel securing device 30 further includes a damping mechanism 34 provided between the rotating mechanism 33 and the wheel mount 31.
Specifically, the wheel mounting seat 31 has a first receiving cavity 311 for receiving the rotating mechanism 33, and a through hole 312 for passing a rotating pin 331 is formed at a connection point with the wheel strut 32. A second receiving cavity 313 is further formed at one side of the wheel mounting seat 31, and slots 314 are formed at both sides of the second receiving cavity 313 for a wheel axle (not shown) to pass through. The rotation mechanism 33 includes a rotation pin 331, a bearing 332, and a fastener 333, the rotation pin 331 passes through the through hole 312 of the wheel mounting seat 31, is vertically disposed between the wheel strut 32 and the wheel mounting seat 31, and the bearing 332 is disposed below the through hole 312 of the wheel mounting seat 31, and the rotation pin 331 passes through the bearing 332 and thus controls the rotation thereof. Fastener 333 is located at the end of swivel nail 331 to position swivel nail 331 within wheel mount 31 via mounting plate 334 and fastener 333.
