There is steering tube 14, the telescoping tube 16 is fixed or unclamped with the steering tube 14 by securing member 18.The top of the telescoping tube 16
Hold leading handle 11.Like the prior art, the tap handle 11 rotates and the steering tube 14 can be driven to rotate.It is described
The bottom of steering tube 14 is provided with a swivel plate 15.
The front end of the main support 9 is further fixed on a bearing support 3, and the bearing support 3 includes two pieces of parallel straight panels, in institute
State and between two pieces of parallel straight panels, be provided with drive mechanism, between the bearing support 3 and the headstock support tube 13, be provided with one turn
Moving axis 131, the two ends of the drive mechanism distinguish pivot in the bearing support 3 and the headstock support tube 13.
With reference to shown in Fig. 3 and Fig. 4, the drive mechanism is bar linkage structure, including the first bar 41 and the second bar 42, described the
By the first pivot 411 on the bearing support 3, second bar 42 is located at the car by the second pivot 421 to one bar 41
On head bracket pipe 13, the end of the middle part of first bar 41 and the second bar 42 is linked together by the 3rd pivot 43, described
The movable end 412 of the first bar 41 is force side.
Force side is pulled, under the driving of the drive mechanism, the headstock support tube 13 is around 131 phase of the rotary shaft
For the bearing support 3 is rotated, and then the foldable reverse tricycle is made to switch under open mode and folded state.
Specifically as shown in figure 3, when the foldable reverse tricycle is in open mode, the 3rd pivot 43 is to front-wheel
The distance between 92 rolling axis less than or equal to first pivot 411 and the second pivot 421 formed link to before
The distance between rolling axis of wheel 92.First bar 41 is resisted against one and is arranged on the 4th axle 44 of the bearing support 3.This
Foldable reverse tricycle when the locking mechanism of sample can make open mode will not produce folding.Further locking mechanism is also wrapped
Include：The 31 outer pivot of one of straight panel of the bearing support 3 is provided with a closing piece 32, when the foldable reverse tricycle is being beaten
During open state, the buckle structure of the closing piece 32 is connected in the 3rd pivot 43.
The bottom of the steering tube 14 is fixed with a fork plate 141, and the steering mechanism of the foldable reverse tricycle includes
Fixed plate 51 and swivel plate 15, the fixed plate 51 are fixed on the bearing support 3, and the swivel plate 15 can by pivot structure
It is rotatably arranged in the fixed plate 51, when the foldable reverse tricycle is in open mode, the fork plate 141 sets up
On the swivel plate 15 and both be relatively fixed.
Specifically, foldable reverse tricycle of the present utility model also includes symmetrical being set by what the swivel plate 15 drove
The pull bar 21 put, one end of two pull bars 21 are individually fixed on a driving piece 22, and the driving piece 22 includes a pivot
Axle 23, the pivot 23 are arranged on the T-shaped support 96.Under the pulling force effect of the pull bar 21, it is described driving piece 22 around
The pivot 23 is rotated and then drives the front-wheel 92 to turn to.
The equal pivot of opposite side of the pull bar 21 of the symmetrical setting is on same connector 24.The connector 24
To be mutually inserted symmetrical two halves formula structure together, the opposite side difference pivot of the pull bar 21 of the symmetrical setting exists
In the wherein half of the two halves formula structure；The two halves formula structure is plugged in together by a round pin 25；The rotary drive
Swivel plate 15 be erected on the connector 24, the two ends of the round pin 25 are stretched in the swivel plate 15.
With reference to shown in Fig. 7 and Fig. 8, the afterbody of the swivel plate 15 is a breach 151；In the fixed plate 51, pivot is provided with
One restoring board 52, the restoring board 52 are alternatively entered or exit the breach 151.When the foldable reverse tricycle exists
During folded state, there is a torsion spring 53 being arranged in the fixed plate 51 to promote the restoring board 52 to enter the breach 151；When
In open mode, the steering tube 14 promotes the restoring board 52 to overcome the torsion spring 53 to the foldable reverse tricycle
Active force exits the breach 151.
Folding process of the present utility model is briefly described below.When the foldable reverse tricycle is in open shape
During state, first bar 41 and the second bar 42 are in the state shown in Fig. 3, and first bar 41 is resisted against one and is arranged in described
On 4th axle 44 of bolster 3.So stable latch-up structure makes headstock support tube 13 with 9 substantially vertical fixation of main support.Now,
With reference to shown in Fig. 1 and Fig. 7, the fork plate 141 is erected on the swivel plate 15 and causes as three faces are firm between the two
Both are relatively fixed, and due to the setting of headstock support tube 13, steering tube 14 is similarly erect, and promote 52 grams of the restoring board
The active force for taking the torsion spring 53 exits the breach 151.So, steering tube 14 is rotated, and drives to shown rotation by fork plate 141
On flap 15, the swivel plate 15 also accordingly can be rotated.As the swivel plate 15 is relatively fixed with connector 24, the connection
Axis of the part 24 substantially also around the steering tube 14 is rotated, and then is pulled or promoted the pull bar positioned at 24 both sides of the connector
21.By taking Fig. 4 as an example, when tricycle needs, the pull bar 21 in figure promotes front-wheel 92 to rotate, and specifically, pull bar 21 is subject to
During thrust, as the reason of pivot 23, the driving piece 22 also receive thrust, the driving piece 22 is schemed around axis X edge
In turn counterclockwise.Likewise, another front-wheel 92 also can be in the pulling force infralevoversion of another pull bar 21.In this moment, due to car
Wheel has the reason of certain frictional force and height difference H with ground, and wheel first can be rolled to the left, make turn inside diameter more when turning left
Plus it is smooth.It is same principle and opposite effect power that vehicle is turned right, and be will not be described here.
When needing to be folded reverse tricycle of the present utility model, first cushion rod 94 is extracted out from main support 9.
Then the movable end 412 of the first bar 41 is pulled, and first bar 41 and the second bar 42 is made in the state shown in Fig. 5 and Fig. 6.At this moment
Due to due to linkage, headstock support tube 13 is rotated relative to the bearing support 3 around the rotary shaft 131, such institute
State steering tube 14 and fork plate 141 is similarly rotated relative to the bearing support 3.Now, the fork plate 141 unclamps the swivel plate
15, the steering tube 14 equally departs from the restoring board 52, and torsion spring 53 promotes the restoring board 52 to enter the breach 151, this
Swivel plate 15 described in sample keeps fixing, so that two front-wheels 92 also keep with respect to positive lock and state that side does not turn.So
It is advantageous in that after reverse tricycle of the present utility model is folded the front-wheel of the tricycle can be walked in tow, in addition,
When the reverse tricycle also being adapted for next time is opened, the fork plate 141 can very successfully swivel plate 15 be stated in clamping residence.
This utility model still has numerous embodiments, all employing equivalents or equivalent transformation and all technologies for being formed
Scheme, all falls within protection domain of the present utility model.
