Detailed description of the invention
With presently preferred embodiments of the present invention, technical scheme is further elaborated below in conjunction with the accompanying drawings.
Seeing the Folding trolley shown in Fig. 1～6, this go-cart includes having expanded position and the vehicle frame of folding position, installation
Vehicle frame lower front front-wheel 3, be arranged on the trailing wheel 4 of vehicle frame lower rear, and for vehicle frame is stably locked at exhibition
Locking device (not shown) under open position or folding position.In the present embodiment described before and after direction according to go-cart just
Custom when often using and define, the direction of advance is front, in contrast be after, accordingly, left and right directions refers to child
Sitting is the left and right directions of child in go-cart.
The vehicle frame of this go-cart includes fixed mount 2, is positioned at two side stands 1 of both sides, and for connecting two side stands 1
And can the lateral frame 5 of horizontal folding.Front-wheel 3 is one and is arranged on below the middle part of fixed mount 2, fixed mount 2 in two ends all to
The arc frame of rear bending.Each side stand 1 includes push rod 11, fore-stock 12, after-poppet 13, seat bar 16, the bottom of fore-stock 12
Being connected to the two ends of fixed mount 2 rotationally, fixed mount 2 is provided with for fore-stock 12 is carried out spacing stopper slot 21, props up afterwards
The top of frame 13 is connected to the top of fore-stock 12 rotationally, and trailing wheel 4 is arranged on the bottom of after-poppet 13.The bottom of push rod 11 turns
It is provided with the first sliding part 14 dynamicly, this first sliding part 14 being axially slidably arranged on after-poppet 13 along after-poppet 13,
Push rod 11 is provided with the second sliding part 15, and the second sliding part 15 is along the push rod 11 axially slidably arranged of push rod 11, front
The top of support 12 rotates with the second sliding part 15 and is connected.First sliding part 14 can use and be set in slidably on after-poppet 13
The first sliding sleeve, the second sliding part 15 can use the second sliding sleeve being set in slidably on push rod 11.The front end of seat bar 16 is hinged
On the middle part of fore-stock 12, its rear end is rotatably connected on bottom or first sliding part 14 of push rod 11, so that
The rear end of seat bar 16 is slidably and rotatably connected on the middle part of after-poppet 13.
In the present embodiment, lateral frame 5 includes first connecting rod 51 and the second connecting rod 52 intersected, the two of first connecting rod 51
End rotate be connected with the after-poppet 13 in left side and second sliding part 15 on right side respectively, the two ends of second connecting rod 52 respectively with the right side
The after-poppet 13 of side and second sliding part 15 in left side rotate connection.Here, locking device is for for by the second sliding part
The locking piece (not shown) being locked on push rod 11, this locking piece has at least two latched position, the two locking bit
Put and correspond respectively to vehicle frame and be in the deployed or the locking piece latched position to the second sliding part 15 during folding position.
Seeing Fig. 1, Fig. 2 to show under the state that stroller frame is fully deployed, locking piece is positioned under the first latched position, the
Two sliding parts 15 are fixedly located in push rod 11 bottom, and the first sliding part 14 is positioned at after-poppet 13 top.When needs unlock, see
Shown in Fig. 3, Fig. 4, the part that first unlocks to the locking between the second sliding part 15 and push rod 11, forward upset push rod 11, first
Sliding part 14 glides along after-poppet 13, and the second sliding part 15 moves fore-stock 12 along the axially upper slide strips of push rod 11 and turns over backward simultaneously
Turn so that vehicle frame fore-and-aft direction generation folding, while the second sliding part 15 is slided, drive first connecting rod 51 and second connecting rod 52
Upper end on move so that lateral frame 5 is horizontal folding along left and right, and the distance between two push rods 11 is gradually reduced, and drives fore-stock
11 realize horizontal folding around the rotation that is rotationally connected between itself and fixed mount 2.To be folded to ad-hoc location time, locking piece position
Being locked on push rod 11 by second sliding part 15 in the second latched position makes vehicle frame stably be under folding position, this vehicle frame
The state erected in vertical direction under folding position, as shown in Figure 5, Figure 6.Otherwise, during unblock, the most only need the part pair that unlocks
The locking of the second sliding sleeve 15, vehicle frame Automatic-expanding under gravity is until the second sliding sleeve 15 is locked in by locking piece again
On push rod 11, vehicle frame is stably in the deployed.During above-mentioned folding or expansion vehicle frame, user is without curved
Waist operates, and folds, launches the most more convenient, and the body frame structure for automotive of this go-cart simultaneously is simple, and rod member is less, and the structure after folding is tight
Gather, take up an area less, there is good Practical Performance.
Above-described embodiment, only for technology design and the feature of the explanation present invention, its object is to allow person skilled in the art
Scholar will appreciate that present disclosure and implements according to this, can not limit the scope of the invention with this.All according to the present invention
The equivalence that spirit is made changes or modifies, and all should contain within protection scope of the present invention.
