Turning joint 200, wherein, between the first push rod 241 and the first front leg strut 251, before the second push rod 242 and second
Connected between supporting leg 252 by the movable joint 200, the first fore-stock and the second fore-stock are realized by the turning joint 200
Folding or expansion.
Each mechanism is described in detail separately below.
Fig. 2, Fig. 3 are referred to, which includes the inner casing 10 and shell 17 that can mutually fasten, unlocking mechanism
It is installed in inner casing 10.Wherein, the first end of inner casing 10 is connected with the first deck 111, second end is connected with the second deck 112；
First deck 111, which connects, first-hand to be blocked 181, second decks 112 connection second-hand the 182, and first deck 111 and second
Seat 112 is hinged with inner casing 10.The both ends of unlocking mechanism are detachably connected with the first deck 111, the second deck 112 respectively.
Wherein, which is compressible unlocking mechanism, can shorten length under the extruding of external force.
Referring to Fig. 4, specifically, which includes the first unlock piece 121, the second unlock piece 122 and a unlock
Spring, the first unlock piece 121 and the second unlock piece 122 make the unlocking mechanism be resilient tying by unlocking 123 elastic connection of spring
Structure, so as to fulfill the compressibility of the unlocking mechanism.
Wherein, the first unlock piece 121 is equipped with the first fixing piece 1212, and the first deck 111 is equipped with and the first fixing piece
1212 the first mounting holes 1112 to match, by the way that the first fixing piece 1212 is arranged in the first mounting hole 1112, make first
Deck 111 is with inner casing 10 from hingedly being changed into being fixedly connected；Similarly, the second unlock piece 122 is equipped with the second fixing piece 1222, and second
Deck 112 is equipped with the second mounting hole 1122 to match with second fixing piece 1222, by the way that the second fixing piece 1222 is blocked
In the second mounting hole 1122, make the first deck 111 with inner casing 10 from hingedly being changed into being fixedly connected.
Refer to Fig. 5, Fig. 6, the first deck 111 is equipped with the first locking skewed slot 1113, and the second deck 112 is equipped with the
Two locking skewed slots 1123.First locking skewed slot 1113 and first mounting hole, 1112 side edge, second locks skewed slot 1123 and the
Two mounting holes, 1122 side edge.
During unlock, the first fixing piece 1212 is separated with the first mounting hole 1112, the second fixing piece 1222 and the second mounting hole
1122 separation, 10 and first deck 111 of inner casing and the second deck 112 are hinged, the first deck 111 and the second deck 112 relative to
Inner casing 10 rotates, and the first fixing piece 1212 is entered in the first locking skewed slot 1113, the second fixing piece 1222 enters the second locking
In skewed slot 1123.
When relocking, the first locking skewed slot 1113 and second locks the first fixing piece of slope driving in skewed slot 1123
1212 and two fixing pieces 1222, so that promote the first unlock piece 121 and the second unlock piece 122 to continue to move toward one another, until the
One unlock piece 121 and the second unlock piece 122 reenter in the first mounting hole 1112 and the second mounting hole 1122 respectively, among this
Pull handle 100 relocks.
Referring to Fig. 7, inner casing 10 be equipped with it is matched with unlocking mechanism together with lock button 13.Wherein, set in inner casing 10
There is the first guide groove, lock button 13 together and be equipped with the first guide part, the first guide part is slideably positioned in first guide groove.
Lock button 13 it should be used to be engaged with unlocking mechanism together, to control the unlock of the perambulator and locking.
Specifically, lock button 1314 includes a solution locked groove 131 for being located at its first side together, and the solution locked groove 131 is in ladder
Shape.
The first guiding surface 132 and the second guiding surface are respectively equipped with a pair of opposite cell wall of the solution locked groove 131
133；And the first side of the first unlock piece 121 is equipped with the first unlock inclined-plane 1213, it is oblique that the second unlock piece 122 is equipped with the second unlock
Face 1223；Further, first guiding surface 132 with first unlock inclined-plane 1213 match, second guiding surface 133 with
Second unlock inclined-plane 1223 matches.
During unlock, promoting should be such that it is sleeved on along the slip of the first guide groove until enclosing outside unlocking mechanism by lock button 1314 together,
First unlock inclined-plane 1213 and the second unlock inclined-plane are respectively acting on by the first guiding surface 132 and the second guiding surface 133
1223, so as to extrude unlocking mechanism so that it is compressed, to achieve the purpose that unlock.
Wherein, unlocking mechanism is tightened for the ease of solution locked groove 131, the notch edges of the solution locked groove 131 are circular arc
Shape, the edge on the first unlock inclined-plane 1213 and the second unlock inclined-plane 1223 is also arc-shaped in unlocking mechanism, so as to solve locked groove 131
Unlocking inclined-plane 1223 to the first unlock inclined-plane 1213 and second has guiding role, and then, when promoting lock button 1314 together,
Unlocking mechanism is set to be moved toward one another in guiding role, until tightening is in solution locked groove 131.
In the present embodiment, the first unlock piece 121 and the second unlock piece 122 are equipped with drag-line 215；Wherein, the first unlock
Drag-line 215 on 121 and second unlock piece 122 of part connects the turning joint 200 on two fore-stock of perambulator respectively, passes through pulling
First drag-line 1211 and the second drag-line 1221 are unlocked turning joint.
In the present embodiment, drag-line 215 is cable wire, thus not flexible easy to force, so as to flexibly control baby
The unlock and locking of car.
During unlock, the first unlock piece 121 and the second unlock piece 122 are drawn close relatively, drive drag-line 215 to be unlocked, and make
Unlocking mechanism is separated with the first deck 111 and the second deck 112, and then makes 10 and first deck 111 of inner casing and the second deck
112 are changed into being articulated and connected.
