Abstract
The invention discloses a folding type tricycle for children, which comprises a front wheel assembly, a front fork stand pipe, a left handlebar, a right handlebar, a tricycle frame, a left rear wheel assembly, a right rear wheel assembly and a tricycle saddle. The front wheel assembly is fixedly connected with the front fork stand pipe and the tricycle saddle is installed on the tricycle frame which is composed of a left tricycle frame and a right tricycle frame. The left tricycle frame and the right tricycle frame are fixedly connected with the left rear wheel assembly and the right rear wheel assembly respectively, and are sheathed and connected on the front fork stand pipe in a rotatable manner through a sleeve at the front end; one respective end facing the front fork stand pipe of the left handle bar and the right handlebar is fixedly connected with a first inner gear wheel and a second inner gear wheel respectively. One of the left handlebar and the right handlebar is fixedly connected with the front fork stand pipe and the first inner gear wheel ant the second inner gear wheel are aligned and superposed. A cavity surrounded by the first inner gear wheel and the second inner gear wheel is internally provided with a clutch gear wheel which can be engaged with the first inner gear wheel and the second inner gear wheel. The clutch gear wheel is pushed between the first inner gear wheel and the second inner gear wheel by a return spring while the other face of the clutch gear wheel matches with a press button. When the press button is pressed down, the clutch gear wheel is only engaged with one of the first inner gear wheel and the second inner gear. After being folded, the folding type tricycle of the invention has small lateral dimension and can be installed in an automobile trunk, thus being convenient for carrying.
Description
(1) technical field
The present invention relates to a kind of folding tricycle for children.
(2) background technology
Existing Foldable tricycle, folding mode be mostly before and after bending, and handlebar can not fold, even if the volume after folding like this is still too big, particularly gauge is excessive, in the boot of the automobile that usually is difficult to pack into.In fact the length of child's tricycle is enough held by the boot of automobile, hinders normally open handlebar, auxiliary rear wheel, thickness of its automobile of packing into etc.And existing folding mode obviously can not reduce the lateral dimension of child's tricycle effectively, can not adapt to the needs of automobile shipment.
(3) summary of the invention
For solve existing folding tricycle for children only can before and after the deficiency of excessive, the automobile trunk of can not packing into of folding, folding back lateral dimension, the present invention proposes that a kind of double left and right sides vehicle frame draws that folding and handlebar is folded into that one, folding back lateral dimension are little in, in the automobile trunk of packing into, folding tricycle for children easy to carry.
The present invention adopts following technical scheme:
Folding tricycle for children, comprise preceding wheel assembly, vertical tube of front fork, left handlebar, right handlebar, vehicle frame, left rear wheel assembly, off hind wheel assembly, saddle, wheel assembly and vertical tube of front fork are affixed before described, saddle is contained on the vehicle frame, vehicle frame is made of left and right vehicle frame, left and right vehicle frame is affixed with left and right rear wheel assembly respectively, and left and right vehicle frame is socketed on the vertical tube of front fork by the sleeve pipe of front end respectively rotationally; End towards vertical tube of front fork of left and right handlebar is connected with first inner gear, secondary annulus respectively, one of left and right handlebar is affixed with vertical tube of front fork, described first inner gear aligns stacked with secondary annulus, be provided with in the cavity that first and second inner gear surrounded can with first and second inner gear ingear clutch gear, described clutch gear is reset spring push between described first and second inner gear, the another side of described clutch gear cooperates with a button, when button is pressed, clutch gear only mesh first and second inner gear one of them.
Further, described saddle comprises a substrate, is hinged with connecting plate on the substrate, connecting plate when deployed position and substrate against, connecting plate, substrate are hinged with left and right vehicle frame respectively.
Principle of work of the present invention is: press the clutch for clutch control button, clutch gear moves downward under the thrust of clutch for clutch control button until breaking away from first inner gear, this moment, left handlebar can rotate relative to vertical tube of front fork, rotating left handlebar aligns with right handlebar, unclamp the clutch for clutch control button again, under the effect of retracing spring, the clutch for clutch control button returns to initial position, this moment, clutch gear and first and second inner gear all meshed, and left handlebar can not rotate relative to vertical tube of front fork; Up move saddle, substrate upwards rotates thereupon, and it is that axle closes up with the vertical tube of front fork that substrate drives left and right vehicle frame by connecting plate, realizes folding.
Beneficial effect of the present invention is: folding back lateral dimension is little, the automobile trunk of packing into is interior, easy to carry.

(5) specific embodiment
The present invention is described further below in conjunction with accompanying drawing.
Folding tricycle for children, wheel assembly 1, vertical tube of front fork 2, left handlebar 3, right handlebar 4, vehicle frame, left rear wheel assembly 5, off hind wheel assembly 6, saddle 7 before comprising, wheel assembly 1 is affixed with vertical tube of front fork 2 before described, saddle 7 is contained on the vehicle frame, vehicle frame is made of left vehicle frame 8 and right vehicle frame 9, left and right vehicle frame is affixed with left and right rear wheel assembly respectively, and left and right vehicle frame is socketed on the vertical tube of front fork 2 rotationally by the sleeve pipe of front end respectively; A left side, end towards vertical tube of front fork of right handlebar is connected with first inner gear 10 respectively, secondary annulus 11, right handlebar and vertical tube of front fork 2 are affixed, 10 alignment of described first inner gear are stacked in secondary annulus 11 tops, first, being provided with in the cavity that two inner geares are surrounded can be with first, two inner gear ingear clutch gears 12, described clutch gear 12 is reset spring 13 pushing tows described first, between two inner geares, the height of described clutch gear 12 is not more than the height of secondary annulus 11, the another side of described clutch gear 12 cooperates with a clutch for clutch control button 14, when button 14 was pressed, 12 of clutch gears meshed with secondary annulus.
Understand easily, first inner gear 10, secondary annulus 11 also can the transposition settings, and this moment, the fixed and movable relation of left and right handlebar was exchanged, and can realize that still handlebar is folding.
Particularly, described clutch for clutch control button 14 belows are provided with three position-limited claws 15, the position-limited claw bottom has the elastic hook of outside bending, first inner gear 10 is provided with the spacing hole 16 that cooperates with three position-limited claws 15, button 14 is packed three position-limited claws 15 in three spacing holes 16 into by elastic deformation, and the design of position-limited claw bottom hook can prevent that position-limited claw from coming off.
