Detailed description of the invention
below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is further elaborated.
referring to the children trolley shown in Fig. 1～3, comprise folding vehicle frame, be located at front portion at the bottom of vehicle frame front-wheel 4, be located at the trailing wheel 5 at rear portion at the bottom of vehicle frame.
vehicle frame comprises push rod 1, front frame 2, after poppet 3, and front-wheel 4 is arranged on the bottom of front frame 2, and trailing wheel 5 is arranged on the bottom of after poppet 3.Push rod 1 comprises lower push-rod 11 and upper push-rod 12, lower push-rod 11 has the lower push-rod 11 of hollow tube chamber, the bottom of upper push-rod 12 can be plugged in slidably along its length and in the above-mentioned hollow tube chamber of lower push-rod 11, make the push rod 1 can be flexible along self length direction, between upper push-rod 12 and lower push-rod 11, be also provided with push rod locking piece 13, this push rod locking piece 13 can be by wherein arranging stop pin on parts in upper push-rod 12 and 11 liang of parts of lower push-rod, on another parts, offering lock hole can realize again, push rod locking piece 13 should at least have two latched positions, thereby lock mutually while making upper push-rod 12 expansion relative to lower push-rod 11 with folding.
the bottom of lower push-rod 11 rotates and is connected with the top of after poppet 3, both places of being rotationally connected are provided with the first locking piece 7, the electric bell that this first locking piece 7 adopts, when electric bell locking, lower push-rod 11 interfixes with after poppet 3, and in the time of electric bell release, lower push-rod 11 can relatively rotate with after poppet 3.Electric bell is the conventional a kind of locking member in this area, no longer its detailed structure is repeated herein, wherein electric bell has two electric bell covers that can mutually rotate, when two electric bell covers rotate mutually, electric bell gets final product release, two electric bell covers are connected on lower push-rod 11 and after poppet 3, only need make like this push rod 1 rotation relative to after poppet 3 can realize the release of electric bell in the time of release.
the top of front frame 2 is connected to the middle part of after poppet 3 rotationally by rotating shaft 6, the axial line of rotating shaft 6 distributes along the left and right directions of vehicle frame.Front frame 2 is provided with when the second locking piece 8, the second locking pieces 8 lock and can makes front frame 2 and after poppet 3 keep fixing with switching place of after poppet 3.Shown in Fig. 1, Fig. 3, the second locking piece 8 comprises the lock 81 that is arranged on regularly after poppet 3 middle parts, on lock 81, offer chute, the length bearing of trend of this chute is mutually vertical with the length bearing of trend of after poppet 3, in above-mentioned chute, be provided with slidably dead bolt 82, the top of front frame 2 offers the locked groove 83 that can insert ordinatedly along direction of slip for dead bolt 82.When the second locking piece 8 locks, the upper support of front frame 2 on lock 81, dead bolt 82 along direction of slip skid off and dead bolt 82 on have at least part to skid off chute outside and be plugged in ordinatedly in locked groove 83, front frame 2 keeps fixing with after poppet 3.In the time of the second locking piece 8 release, dead bolt 82 departs from locked groove 83, and front frame 2 can relatively rotate with after poppet 3.The second locking piece 8 also comprises an elastic component (not shown), thereby dead bolt 82 can be stably inserted in locked groove 83 in the time that the second locking piece 8 locks, and the elastic force of above-mentioned elastic component can drive dead bolt 82 to slide and lock in locked groove 83 when the traction force of dead bolt is eliminated in the time of release.
on above-mentioned vehicle frame, the first locking piece 7 and the second locking piece 8 linkage of unlocking ground arrange, and only need like this one of them locking piece release can carry out the release of go-cart and fold in the time of Folding trolley.Here, between the dead bolt 82 of the electric bell of the first locking piece 7 and the second locking piece 8, be fixed with trailing cable (not shown), trailing cable one end is fixedly connected on dead bolt 82, its other end is fixed on an electric bell cover in two counterrotating electric bell covers of electric bell, or is fixed on that on electric bell, other can produce on the parts of displacement in the time of electric bell release.In the time of electric bell release, trailing cable is connected to the end under tension on electric bell and pulls dead bolt 82 like this, makes dead bolt 82 slide and depart from locked groove 83 and realize the release of the second locking piece 8 along chute.
in the time that vehicle frame launches, the first locking piece 7 and the second locking piece 8 are all in the lock state, upper push-rod 12 and lower push-rod 11 relative deformations of push rod 1, and deployed condition is as shown in Figure 1.In the time of needs folding stand, first upper push-rod 12 is reclaimed along lower push-rod 11, make the contraction in length of push rod 1, then the push rod 1 of turning over, the electric bell release of the first locking piece 7, in electric bell releasing process, pull trailing cable, make trailing cable pull dead bolt 82 to slide along the chute on lock 81, the final disengaging in locked groove 83, the second also release of locking piece 8, like this, turns over push rod 1 until itself and after poppet 3 are folded after continuation, front frame 26 rotates and draws close with after poppet 3, push rod 1 relative to after poppet 3 around the shaft, is finally folded into state as shown in Figure 3.
in the time that needs launch vehicle frame, push rod 1 is carried and upset forward, until the relative after poppet 3 of push rod 1 turn to electric bell when locking of the first locking piece 7, trailing cable is released, dead bolt 82 skids off along chute under elastic component effect, when turning over before push rod 1, the bottom of front frame 2 is drawn close towards the bottom of after poppet 3, until the top of front frame 2 is while keeping out mutually with the lock 81 on after poppet 3, dead bolt 82 inserts in locked groove 83, front frame 2 and after poppet 3 are locked, finally again the upper push-rod on push rod 1 12 is pulled out from lower push-rod 11, go-cart returns back to the deployed condition shown in Fig. 1.
above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection domain of the present utility model.
