Abstract
The invention relates to a front wheel mechanism of a children cart, which comprises a front wheel stent, a cross bar and front wheel components which are arranged on the two ends of the cross bar respectively. One of the two components on the approximately middle part of the cross bar and the front part of the front wheel stent is provided with an inserting space and the other component is provided with a plug-in which is inserted in the inserting space. A locking mechanism is arranged between the front wheel stent and the cross bar. The locking mechanism is provided with a locking state and an unlocking state; when the locking mechanism is in the locking state, the cross bar and the front wheel stent are arranged connectively; when the locking mechanism is in the unlocking state, the cross bar and the front wheel stent can be arranged separately. With better anti-vibration effect, an elastic anti-vibration component is arranged between the front wheel stent and the cross bar.
