Referring to shown in Fig. 1 to Fig. 4, also include commutation handle 5 and bar 6, the bottom of the handle 5 that commutates per side side stand 10 It is connected with the bottom of push rod 4 or with the top phase pivot of front support rod 1, in the present embodiment, the lower pivot connection of the commutation handle 5 On the bottom of push rod 4, bar 6 extends along the longitudinal direction and its rear portion is pivotally connected in the bottom of push rod 4, specifically, helps The rear portion of hand lever 6 and the bottom of commutation handle 5 can be by being connected to around same axis of rotation on the bottom of push rod 4.Commutation is pushed away There is from front to back the positive operating position that gradually updip extends and the reverse operation position that gradually updip extends from back to front 5 Put, be additionally provided with the side stand 10 of both sides respectively for commutation handle 5 is locked in above-mentioned positive operating position or reverse operation Handle locking mechanism under position.In the present embodiment, when the handle 5 that commutates is in positive operating position, thread-changing handle 5 with push away Bar 4 is mutually drawn close, and commutation handle 5 is locked on push rod 4, as shown in Figure 1 and Figure 2 by handle locking mechanism；When commutation handle 5 is in During reverse operation position, commutation handle 5 is mutually drawn close with bar 6, and commutation handle 5 is locked in bar 6 by handle locking mechanism On, as shown in Figure 3, Figure 4.

Here, referring to shown in Fig. 1 to Fig. 4, handle locking mechanism includes slidably being located on commutation handle 5 and having lock The sliding sleeve 7 in hole, the first lock 8 on push rod 4, the second lock 9 on bar 6, when the first lock 8 inserts sliding sleeve When in the lockhole on 7, commutation handle 5 is locked in positive operating position, and trammer can carry out at the rear of vehicle frame；When the second lock When in the lockhole on 9 insertion sliding sleeves 7, commutation handle 5 is locked in reverse operation position, and trammer can carry out in the front of vehicle frame. Sliding sleeve 7 slides up and down along commutation handle 5 and realizes the locking of the handle locking mechanism and unlock.

Referring to shown in Fig. 1, Fig. 3 and Fig. 6, the side stand 10 of both sides is rotatedly connected with stull component respectively.Specifically, Stull component includes the first cross bar 11, two ends difference that two ends are pivotally connected on both sides front support rod 1 by axle a, axle a ' respectively The second cross bar 12, two ends on both sides back stay 2 is pivotally connected in by axle b, axle b ' pivotally connected by axle c, axle c ' respectively The 3rd cross bar 13, two ends on both sides seats bar 3 is pivotally connected in the 4th cross bar on both sides push rod 4 by axle d, axle d ' respectively 14th, two ends are pivotally connected in the 5th cross bar 15 that both sides are commutated on handle 5 by axle e, axle e ' respectively, and two ends pass through respectively Axle f, axle f ' are pivotally connected in the 6th cross bar 16 on both sides bar 6.Wherein, the 6th cross bar 16 is located at both sides bar 6 Between front portion, between the top of both sides commutation handle 5, the 4th cross bar 14 is located at the top of both sides push rod 4 for the 5th cross bar 15 Between, the 3rd cross bar 13 between the rear portion of both sides seats bar 3, the second cross bar 12 between the rear portion of both sides back stay 2, the One cross bar 11 is between the bottom of both sides front support rod 1.

Referring to shown in Fig. 1 to Fig. 4, when children trolley is in deployed condition, stull component is supported on two in left-right direction Between the side stand 10 of side, per the quadric chain that the front support rod 1 on side side stand 10, back stay 2, seat bar 3 and push rod 4 are formed In the deployed state, user can be changed commutation handle 5 to forward direction as shown in Figure 1 and Figure 2 using needs according to implementation for locking Operating position, or commutation handle 5 is changed to reverse operation position as shown in Figure 3, Figure 4.

When needing to fold up children trolley, first so that bar 6, commutation handle 5 and push rod 4 are mutually drawn close, specifically Commutation handle 5 can be locked with push rod 4 by handle locking mechanism, then bar 6 is flipped up and is drawn close with push rod 4； Then the Lock of handlebar joint of both sides is unlocked so that push rod 4 is turned over together with commutation handle 5 and bar 6, front Bar 1, back stay 2 and seat bar 3 are relatively rotated therewith, until front support rod 1, back stay 2, seat bar 3, push rod 4, commutation are pushed away on the same side 5 and bar 6 are drawn in together along the longitudinal direction, is realized longitudinal folding on the fore-and-aft direction of vehicle frame.

Complete it is longitudinal folding after vehicle frame as shown in Figure 5, Figure 6, now, the first cross bar 11, the second cross bar 12, the 3rd cross bar 13rd, the 4th cross bar 14, the 5th cross bar 15, the 6th cross bar 16 respectively be located at different height and positions, and the left side of vehicle frame on axle a, Axle b, axle c, axle d, axle e, the axial line of axle f are parallel to each other or collinearly extend, axle a ', axle b ', axle c ', axle on the right side of vehicle frame D ', axle e ', the axial line of axle f ' are parallel to each other or collinearly extend, and use the setting side of conllinear extension in the present embodiment Formula, i.e. upper axle a, axle b, axle c, axle d, axle e, the axial line of axle f generally collinearly extend on the left of vehicle frame, in its common rotation The heart line such as MM ' in Fig. 6, upper axle a ' on the right side of vehicle frame, axle b ', axle c ', axle d ', axle e ', axle f ' axial line it is also generally conllinear Extend, the NN ' in its common rotary centerline such as Fig. 6.

Then vehicle frame is carried out laterally folded：The side stand 10 in left side is rotated and relative stull around rotary centerline MM ' Component draws in, the side stand 10 on right side is rotated around rotary centerline NN ' and relative stull component draws in, specially by the side of both sides Support 10 inwardly overturns 90 ° or so opposite to each other with respect to stull component respectively, and finally, the side stand 10 of both sides is drawn close in stull component The same side on, as shown in Figure 7, Figure 8, front support rod 1 on side stand 10, back stay 2, seat bar 3, push rod 4, commutation handle 5 and help Hand lever 6 is drawn close on stull component, and vehicle frame stands on ground certainly by commutation handle 5 and two groups of wheel assemblies 30.

To sum up, children trolley of the present utility model, its vehicle frame in the deployed state, can pass through to adjust the work of commutation handle 5 Make position and positive implementation can be carried out or reversely carried out.The rod member quantity of the vehicle frame is few, simple for structure, the energy during vehicle frame folding Enough each rod members on the same side side stand 10 rotate along the longitudinal direction draw in and realize vehicle frame it is longitudinal folding after, then by both sides Side stand 10 inwardly overturns in opposite directions and draws close to stull component and realize the laterally folded of vehicle frame, and the vehicle frame after folding is in flat Shape cramped construction and ground can be stood on certainly, the daily storage for user provides great convenience with carrying.

Above-described embodiment only to illustrate technology design of the present utility model and feature, its object is to allow and be familiar with technique Personage will appreciate that content of the present utility model and implement according to this, protection domain of the present utility model can not be limited with this. All equivalence changes made according to this utility model spirit or modification, should all cover protection domain of the present utility model it It is interior.
