Embodiment
As shown in Figures 1 to 6, a kind of children trolley described in the utility model, the front-wheel 7 comprise the vehicle frame with expansion state and folded state, being arranged on vehicle frame lower front portion, the trailing wheel 8 being arranged on vehicle frame lower rear and the locking gear for vehicle frame being locked in expansion/folded state. Described vehicle frame comprises front wheel support 1, rear wheel support 2 and push rod 3. Described front-wheel 7 is arranged on the bottom of front wheel support 1, and described trailing wheel 8 is arranged on the bottom of rear wheel support 2.
Described front wheel support 1 comprises the front-wheel pole 5 that bottom is connected and the connecting rod 6 being fixedly installed on front-wheel pole 5 top with front-wheel 7, and described connecting rod 6 intersects vertically with front-wheel pole 5. In the present embodiment, connecting rod 6 is weldingly fixed on front-wheel pole 5. Described connecting rod 6 is connected by the first sliding cover 4 with rear wheel support 2, and the described first sliding cover 4 rotation is arranged on the end of connecting rod 6 away from front-wheel pole 5. Described rear wheel support 2 is located in the first sliding cover 4 and can slide in the first sliding cover 4. Described push rod 3 is slidably arranged on front wheel support 1, and the bottom of described push rod 3 and the upper end of rear wheel support 2 are rotationally connected by pin. The upper end of described front-wheel pole 5 is fixing is equiped with the 2nd sliding cover 9, and described push rod 3 is located in the 2nd sliding cover 9 slidably. The junction of described push rod 3 and rear wheel support 2 is lower than the position at the 2nd sliding cover 9 places. Described front wheel support 1, rear wheel support 2, push rod 3 and the first sliding cover 4 formation slide crank block mechanism.
When vehicle frame is in expansion state, front wheel support 1 and rear wheel support 2 support vertical mutually, and described push rod 3 stretches towards the direction away from front-wheel 7; When vehicle frame is in folded state, described front wheel support 1 is drawn close mutually with rear wheel support 2, and described push rod 3 shrinks towards near the direction of front-wheel 7.
When locking gear unlocks, described push rod 3 can slide along the bearing of trend of front-wheel pole 5. Described push rod 3 slides and drives rear wheel support 2 to move, and when described push rod 3 slides towards near the direction of front-wheel 7, the upper end of described rear wheel support 2 is drawn close towards front-wheel 7 direction; When described push rod 3 slides towards the direction away from front-wheel 7, the upper end of described rear wheel support 2 is pulled up towards moving away from front-wheel 7 direction.
When the children trolley launching state is folded, first locking gear is unlocked, then push rod 3 front wheel 7 direction is promoted, push rod 3 is slide downward in the 2nd sliding cover 9, described front wheel support 1, rear wheel support 2, push rod 3 and the first sliding cover 4 formation slide crank block mechanism running, rear wheel support 2 front wheel under the drive of push rod 3 is drawn close, and the angle between rear wheel support 2 and push rod 2 diminishes gradually, push rod 3, front wheel support 1 have so far folded together with mutually drawing close with rear wheel support 2.
When being launched by the children trolley of folded state, the motion of whole vehicle frame is with contrary time folding. First upwards being lifted by push rod 3, push rod 3 upwards slides along the bearing of trend of front-wheel pole 5, and rear wheel support 2 is also upwards pulled up under the drive of push rod 3, and the angle between push rod 3 and rear wheel support 2 increases to gradually to be launched completely.
From above-mentioned, the vehicle frame component of children trolley described in the utility model only have limited several such as the sliding cover 4 of front wheel support 1, rear wheel support 2, push rod 3, first, the 2nd sliding cover 9, and vehicle frame is succinct, and structure is simple, with low cost. And folding step is simple, it is possible to a step is folding to put in place, convenient and easy. After folding, owing to parts are less, mutually draw close compact after folding, take space little, be convenient to carry.
As mentioned above, it is necessary, we are illustrated according to objective of the present utility model completely, but the utility model is not limited to above-described embodiment and implementation method. The practitioner of correlative technology field can carry out different changes and enforcement in the scope that technological thought of the present utility model is permitted.
