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 the stroller frame with expansion and folded state, go-cart car
Frame is included lower supporter and bottom and lower supporter and is rotated the push rod 2 being connected by rotating shaft 3, push rod 23 lower supporters relatively around the shaft
On the stroke rotating, there is positive fixed position and reverse fixed position, children trolley is also included for being just locked in push rod 2
Locking mechanism to fixed position and 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,
Locking mechanism includes being rotatably arranged at commutation handle 41 on push rod 2, is fixedly installed on the another of connecting rod 15
First locking column 42 of one end, be fixedly installed on bar 14 front portion the second locking column 43, when push rod 2 is on lower supporter
When being in positive fixed position, commutation handle 41 is matched with the first locking column 42, as shown in Fig. 2 when push rod 2 is in lower supporter
On when being in reverse fixed position, commutation handle 41 is matched with the second locking column 43；When commutation handle 41 and the first locking
When post 42 and the second locking column 43 all disengage, push rod 2 can commutate in front and back, as shown in Figure 3.
When children trolley is in deployed condition, the distance between rotating shaft 3 and the first locking column 42, rotating shaft 3 and the second lock
The two is identical for the distance between fixed column 43；When children trolley is in folded state, between rotating shaft 3 and the first locking column 42 away from
From the distance between, rotating shaft 3 and second locking column 43, the two is different.
When children trolley in a folded configuration, if push rod 2 still can positive fixed position and reverse fixed position it
Between when mutually changing, after push rod 2 commutation, commutation handle 41 can not be matched with the first locking column 42 or the second locking column 43 locking,
As shown in fig. 6, and when in this state children trolley being launched, commutation handle 41 still can not be with the first locking column 42 or the second
Locking column 43 matches locking, as shown in fig. 7, so that there is potential safety hazard when children trolley uses in the folded-out situation,
For avoiding this situation to occur, this children trolley is additionally included in children trolley and is under folded state and is used for limiting push rod 2 just
To mutually conversion between fixed position and reverse fixed position thus push rod 2 is fixed on positive fixed position and reverse fixed bit
Put the position-limit mechanism at place.
Specifically, position-limit mechanism includes the positive stop 5 being fixedly installed on lower supporter, when children trolley is in expansion shape
During state, positive stop 5 away from commutation handle 41, thus not affecting the switch operation of push rod 2, as illustrated in figures 1 and 8；Work as child
When go-cart is in folded state, positive stop 5 is matched with commutation handle 41, so that commutation handle 41 can not disengage the first lock
Fixed column 42 or the second locking column 43, make push rod 2 can not commutate and be fixed on positive fixed position or reverse fixed position, such as
Shown in Fig. 4 and Fig. 9.
In the present embodiment, positive stop 5 is fixedly installed on the rear portion of bar 14, when children trolley is in deployed condition
When, positive stop 5 is located at the top of commutation handle 41 and keeps at a certain distance away, thus not affecting push rod and commutation handle 41 between
2 mutually change between positive fixed position and reverse fixed position；When children trolley is in folded state, positive stop 5
Match thus push rod 2 is fixed on positive fixed position with commutation handle 41.
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.
