Specific embodiment
Come with specific embodiment below in conjunction with the accompanying drawings the technical solution of the utility model is further elaborated.
Referring to a kind of children trolley shown in Fig. 1 ~ Fig. 9, including stroller frame, stroller frame includes lower supporter and bottom
Rotated the push rod 2 being connected by rotating shaft 3 with lower supporter, push rod 23 has forward direction around the shaft on the stroke that lower supporter rotates
Fixed position and reverse fixed position, as shown in Figures 2 and 3, stroller frame has expansion and folded state, and children trolley also wraps
Include for by stroller frame locking first locking mechanism in the deployed state, be used for for push rod 2 being locked in positive fixed position
Second locking mechanism, the unblock knob 4 for making first locking mechanism unlock with reverse fixed position.
Lower supporter includes fore-stock 11, after-poppet 12, seat bar 13, bar 14, connecting rod 15 and sliding sleeve 16, and fore-stock 11 is used
In installing front component, after-poppet 12 is used for installing wheel assembly, and seat bar 13 and bar 14 all extend along the longitudinal direction, front
The top of frame 11, the top of after-poppet 12 are rotated with the front portion of bar 14 respectively and are connected, and sliding sleeve 16 can be along after-poppet 12
Length bearing of trend be slidably arranged on after-poppet 12, the one end of connecting rod 15 is rotated with sliding sleeve 16 and is connected, the other end
Portion is rotated with the rear portion of bar 14 and is connected, and the front portion of seat bar 13 is rotated with fore-stock 11 and is connected, the rear portion of seat bar 13 with
Connecting rod 15 rotates connection, and the bottom of push rod 2 is rotated by rotating shaft 3 with sliding sleeve 16 and is connected.In the present embodiment, under push rod 2
Portion, the one end of connecting rod 15, the rear portion of seat bar 13, sliding sleeve 16 are all rotated by rotating shaft 3 same axis and connect;It is in stroller frame
Deployed condition, and when push rod 2 is locked in positive fixed position, connecting rod 15 parallels setting with push rod 2.So, after-poppet 12,
Form a slider-crank mechanism, present bar 13, fore-stock 11, bar 14 and between bar 14, connecting rod 15 and sliding sleeve 16
Formed between connecting rod 15 quadric chain,
In the present embodiment, first locking mechanism is arranged between sliding sleeve 16 and after-poppet 12.A kind of specific embodiment, the
One locking mechanism include the stop pin 51 being slidably arranged on after-poppet 12, be movably arranged on after-poppet 12 first
Actuator 52, stop pin 51 is matched with the first actuator 52, when first locking mechanism is in the lock state, 51 points of stop pin
Do not match with after-poppet 12 and sliding sleeve 16, when operation unblock knob 4 makes the first actuator 52 after-poppet 12 activity relatively, drive
Make stop pin 51 slide to disengage with sliding sleeve 16, first locking mechanism just unlocks, and this children trolley just can fold.
Commutation handle 61 that second locking mechanism includes being rotatably arranged on push rod 2, it is fixedly installed on connecting rod 15
On the first locking column 62, be fixedly installed on bar 14 leading section the second locking column 63, when push rod 2 is located on lower supporter
When positive fixed position, commutation handle 61 is matched with the first locking column 62, as shown in Fig. 2 when push rod 2 is on lower supporter
When being in reverse fixed position, commutation handle 61 is matched with the second locking column 63, as shown in Figure 3.
Unblock knob 4 is arranged on push rod 2, for avoiding push rod 2 phase between positive fixed position and reverse fixed position
Maloperation unblock knob 4 when mutually changing, so that first locking mechanism unblock, makes children trolley fold, as shown in figure 5, this youngster
Virgin go-cart also includes position-limit mechanism, limited block 71 that position-limit mechanism includes being slidably arranged on connecting rod 15, is fixedly installed
The second actuator 72 on push rod 2, specifically, connecting rod 15 has the tube chamber extending along its length, and limited block 71 includes
The slide block 71a being slidably arranged in the tube chamber and limited post 71b being fixedly installed on slide block 71a, in the pipe of connecting rod 15
The side wall in chamber is provided with the chute 15a of the length bearing of trend extension along connecting rod 15, and chute 15a is matched with limited post 71b, limit
The one end of position post 71b is fixedly installed on slide block 71a, and the other end passes through chute 15a, when slide block 71a slides in tube chamber
When, limited post 71b slides in chute 15a, and by chute 15a, its glide direction and distance is defined.This enforcement
In example, when push rod 2 is locked in positive fixed position and reverse fixed position, limited post 71b is located at the upper end of chute 15a
Portion, when push rod 2 is mutually changed between positive fixed position and reverse fixed position, limited post 71b is located under chute 15a
End.
When push rod 2 is locked in positive fixed position and reverse fixed position, that is, commutation handle 61 is locked with first respectively
Fixed column 62 and the second locking column 63 match, as shown in Fig. 2, Fig. 3, Fig. 6 and Fig. 7, now the second actuator 72 and limited post 71b
The other end match, specifically, the second actuator 72 is provided with the boss 72a matching with limited post 71b, i.e. limited post
71b is matched with boss 72a, thus ordering about limited block 71 away from the first actuator 52, now, operation unblock knob 4 can make
First actuator 52 activity makes first locking mechanism unlock thus ordering about stop pin 51 and sliding, after first locking mechanism unblock, should
Children trolley can fold.
When push rod 2 commutates to reverse fixed position from positive fixed position, that is, commutation handle 61 and the first locking column 62 take off
After opening cooperation, push rod 23 is rotated to the direction being coordinated with the second locking column 63 around the shaft relative to lower supporter, such as Fig. 4, Fig. 8 and Fig. 9
Shown, so that the cooperation between the boss 72a on limited post 71b and the second actuator 72 is disengaged during this, limited block 71 just may be used
Length along connecting rod 15 extends slide downward until limited block 71 matches with the first actuator 52 so that the first actuator 52 is solid
It is scheduled on stiff on lower supporter, thus stop pin 51 can not be ordered about sliding, now, even if operation unlocks knob 4 nor makes
First locking mechanism unlocks, and that is, in the commutation process of whole push rod 2, first locking mechanism is in the state of locking all the time, from
And make children trolley be in stable deployed condition, improve the security performance of this children trolley.
Action when push rod 2 commutates to positive fixed position from reverse fixed position and push rod 2 are from positive fixed position
Identical to the action of reverse fixed position commutation.
Above-described embodiment is only that technology design of the present utility model and feature are described, its object is to allow and is 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, all should cover protection domain of the present utility model it
Interior.
