The specific embodiment
Below in conjunction with accompanying drawing specific embodiment of the utility model is described.
As shown in Figure 1, this children trolley is a Foldable umbrella shaped handle cart, and its vehicle frame 1 comprises:
Foot lever 2 before the pair of right and left;
Foot lever 3 after the pair of right and left;
Pair of right and left push rod 7, push rod 7 rotate with preceding foot lever 2 and back foot lever 3 simultaneously and are connected;
Pair of right and left seat bar 4, this bar 4 be connected across before foot lever 2 the middle part and the back foot lever 3 the middle part between;
The end cross strut 5 that a pair of rod member that is hinged by the middle part constitutes, 4 ends of this end cross strut 5 rotate with a pair of preceding foot lever 2 and a pair of back foot lever 3 respectively and are connected;
The back cross strut 6 that a pair of rod member that is hinged by the middle part constitutes, 4 ends of this back cross strut 6 rotate with a pair of back foot lever 3 and pair of push rods 7 respectively and are connected.
The lockout mechanism of implementing according to the utility model 70 is arranged on the point of connection of push rod 7 and preceding foot lever 2, and its concrete structure is shown in accompanying drawing 2 and accompanying drawing 3.
Be enclosed within the latch hook 40 of the ring-type in the first bar portion 11, this latch hook 40 can rotate around the first bar portion 11;
Be opened in latch hook 40 away from the lock slots 41 on the end of the first bar portion 11, this lock slots 41 is used to hold described second taper 22.
Latch hook 40 away from an end of the first bar portion 11 towards a lateral buckling, form the hook portion 42 of a U font, then the inner space of this U font is lock slots 41.The cornerite of lock slots 41 is 225 degree, and this angle can just guarantee that second taper 22 can not deviate from lock slots 41.In the first bar portion, 11 rotating process, latch hook 40 possesses the unlocked position that second taper 22 is embedded in the latched position in the lock slots 41 and makes second taper 22 deviate from the lock slots 41.
In the outside of hook portion 42, protrusion is provided with a strip handle, makes things convenient for the user to operate.
As shown in Figure 1, the second bar portion 21 of first taper 12 of push rod 7, preceding foot lever 2, seat bar 4, back foot lever 3 these 4 rod members have formed four-bar linkage.Folding by this four-bar linkage, and end cross strut 5, back cross strut 6 is folding can become folded state from deployed condition with vehicle frame 1.And, just can realize the fixing of whole vehicle frame 1 by the angle between push rod 7 and the preceding foot lever 2 is fixed.Therefore, this lockout mechanism 70 is installed between push rod 7 and the preceding foot lever 2,, just can realizes vehicle frame 1 is fixed under the deployed condition by with 80 degree of the angle stuck-at-between push rod 7 and the preceding foot lever 2.
As mentioned above, we are illustrated according to aim of the present utility model fully, but the utility model is not limited to the foregoing description and implementation method.The practitioner of correlative technology field can carry out different variations and enforcement in the scope of technological thought permission of the present utility model.
