Before the utility model discloses a kind of doll carriage, rear tread adjustment structure, including vehicle frame, it is arranged on the front component below vehicle frame, and wheel assembly, before being connected with by lateral shaft on rear side of vehicle frame, the backward after-poppet assembly being in tilted layout, wheel assembly is arranged on after-poppet assembly lower end, after-poppet assembly can rotate around before and after lateral shaft, it has first, second operating position, when after-poppet assembly is in the first operating position, after-poppet assembly is positioned on front side of lateral shaft, and it is low to be in front end, the state that rear end is high, when after-poppet assembly is in the second operating position, after-poppet assembly is positioned on rear side of lateral shaft, and it is low to be in front end, the state that rear end is high, this adjustment structure also includes can be first, second operating position realizes the locking mechanism of locking to vehicle frame and after-poppet assembly；This utility model is by rotating and lock before and after after-poppet assembly, it is achieved front and rear wheel away from regulation, simple in construction, cost is relatively low, and regulation is got up the most very convenient.
Description
Technical field
This utility model relates to the front and rear wheel of a kind of doll carriage away from adjustment structure.
Background technology
Doll carriage has been the instrument that the trip of a kind of infant is indispensable, and user is pursuing doll carriage
Outside firm, safe basic demand, increasingly pay attention to the multifunctionality of doll carriage.The most on the market
Occur in that can the doll carriage of single, double people seat conversion, two seat front-end geometry arrange, this structure is past
Toward requiring that the distance between the front wheels and rear wheels of go-cart can regulate, to improve stability in the large.
Summary of the invention
This utility model purpose is: providing the front and rear wheel of a kind of doll carriage away from adjustment structure, it passes through
Rotate before and after after-poppet assembly and lock, it is achieved front and rear wheel away from regulation, simple in construction, cost is relatively
Low, and regulate the most very convenient.
The technical solution of the utility model is: the front and rear wheel of a kind of doll carriage away from adjustment structure, including
Vehicle frame, it is arranged on the front component below vehicle frame and wheel assembly, by laterally on rear side of described vehicle frame
Pivot pin is connected to the after-poppet assembly that forward and backward is in tilted layout, and described wheel assembly is arranged on after-poppet assembly
Lower end, described after-poppet assembly can rotate around before and after lateral shaft, and it has the first operating position and second
Operating position, when after-poppet assembly is in the first operating position, after-poppet assembly is positioned on front side of lateral shaft,
And it is in the state that front end is low, rear end is high, and when after-poppet assembly is in the second operating position, after-poppet
Assembly is positioned on rear side of lateral shaft, and is in the state that front end is low, rear end is high, and described adjustment structure also includes
In first, second operating position, vehicle frame and after-poppet assembly can be realized the locking mechanism of locking.
Further, when described after-poppet assembly is in the first operating position, place, lateral shaft axle center with
It is formed with angle between plane A and plane B1 at lateral shaft axle center and place, wheel shaft axle center that ground is vertical
β, when described after-poppet assembly is in the second operating position, place, lateral shaft axle center perpendicular to the ground
Angle α, described folder it is formed with between plane B2 at plane A and lateral shaft axle center and place, wheel shaft axle center
Angle α is equal with angle β.During above two operating position, angle α is equal to angle β, in simple terms,
Be exactly plane B1 and plane B2 opposite planar A is mirror-image arrangement, this design can ensure that front and rear wheel away from
Before regulation and after regulation, the height on rear side of vehicle frame is always consistent, and then it is comfortable to ensure that entirety is taken
Property.
The utility model has the advantages that:
1. this utility model is by rotating and lock before and after after-poppet assembly, it is achieved front and rear wheel away from
Regulation, simple in construction, cost is relatively low, and regulation is got up the most very convenient.
2. when in this utility model, after-poppet assembly is in two kinds of operating positions, plane B1 and plane B2
Opposite planar A is mirror-image arrangement, this design can ensure that front and rear wheel away from regulation before and regulate after, after vehicle frame
The height of side is always consistent, and then ensures the comfortableness that entirety is taken.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings and this utility model is further described by embodiment:
Fig. 1 is the after-poppet of the present utility model easy structure schematic diagram when being in the first operating position；
Fig. 2 is the after-poppet of the present utility model easy structure schematic diagram when being in the first operating position.
Wherein: 1 vehicle frame；2 front components；3 wheel assemblies；4 lateral shafts；5 after-poppet assemblies.
Detailed description of the invention
Embodiment: as depicted in figs. 1 and 2, the front and rear wheel of a kind of doll carriage is away from adjustment structure, bag
Include vehicle frame 1, be arranged on the front component 2 below vehicle frame 1 and wheel assembly 3, described vehicle frame 1
Rear side is connected with the after-poppet assembly 5 that forward and backward is in tilted layout, described wheel assembly by lateral shaft 4
3 are arranged on after-poppet assembly 5 lower end, and described after-poppet assembly 5 can rotate around before and after lateral shaft 4,
It has the first operating position and the second operating position, when after-poppet assembly 5 is in the first operating position,
After-poppet assembly 5 is positioned on front side of lateral shaft 4, and is in the state that front end is low, rear end is high, works as after-poppet
When assembly 5 is in the second operating position, after-poppet assembly 5 is positioned on rear side of lateral shaft 4, and is in front end
The state that low, rear end is high, described adjustment structure also includes can be in first, second operating position to vehicle frame 1
With the locking mechanism that after-poppet assembly 5 realizes locking.
Further, when described after-poppet assembly 5 is in the first operating position, place, lateral shaft 4 axle center
Plane A perpendicular to the ground and plane B1 at lateral shaft 4 axle center and place, wheel shaft axle center between formed
Have angle β, when described after-poppet assembly 5 is in the second operating position, place, lateral shaft 4 axle center with
