Embodiment
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is further elaborated.
See the children trolley shown in Fig. 1 ~ Fig. 4, this children trolley comprise have launch and folded state stroller frame 1, be arranged on stroller frame 1 front portion, the end front component 5, be arranged on stroller frame 1 rear portion, the end wheel assembly 6, for stroller frame 1 is locked lockout mechanism in the deployed state.
Stroller frame 1 comprises front support 11, after poppet 12, push rod 13, seat bar 14 and sliding part 15. Front component 5 is arranged on the bottom of front support 11; After poppet 12 comprises the back stay 121 extended along the vertical direction and the rear wheel support 122 being fixedly installed on back stay 121 bottom, wheel assembly 6 is arranged on the bottom of rear wheel support 122, back stay 121 tilts to extend forward from top to bottom, and rear wheel support 122 extends to rear-inclined from top to bottom; The top of the bottom of push rod 13 and back stay 121 is rotated by the first axle 16 and is connected, and when go-cart vehicle carriage 1 is in expansion state, push rod 13 is different from the bearing of trend of back stay 121; Seat bar 14 extends along the longitudinal direction, and being rotated by the 2nd axle 17 between the front portion of seat bar 14 with front support 11 is connected, and being rotated by the 3rd axle 18 between the rear portion of seat bar 14 with back stay 121 is connected; Sliding part 15 can be slidably arranged on back stay 121 along the bearing of trend of back stay 121, the top of front support 11 and sliding part 15 are rotated by the 4th axle 19 and are connected, in the present embodiment, back stay 121 is provided with the fluting extended along the vertical direction, and sliding part 15 is located in this fluting and can slide along the bearing of trend of this fluting. Like this, between front support 11, seat bar 14, back stay 121 and sliding part 15, a slide crank block mechanism is just formed.
Lockout mechanism comprises the 2nd lock machine structure being arranged between push rod 13 with back stay 121 for being used for locking the relative position of slide crank block mechanism mutually between the first lock machine structure locked mutually by the relative position of the two, two parts being arranged in above-mentioned slide crank block mechanism to be flexibly connected mutually arbitrarily; first lock machine structure and the 2nd lock machine structure are not all the technical essentials of this patent protection, can adopt technical scheme of the prior art.
This children trolley also comprises carries band 21, and the both ends carrying band 21 are separately fixed at the left and right sides of a bar 14, and back stay 121 is established finite place piece 22, and spacing part 22 is for when band 21 is carried in lift, to carrying band 21, to carry out constraint spacing. In the present embodiment, it is formed between spacing part 22 and back stay 121 and holds space, carry band 21 to pass from this accommodation space, and the point of fixity carried on the present bar 14 of band 21 is positioned at the front of the 3rd axle 18, on back stay 121, spacing part 22 is positioned at the top of the 3rd axle 18, like this when this children trolley is folding, upwards band 21 is carried in lift, makes a bar 14 and back stay 121 rotate around the 3rd axle 18 respectively and draw close under the acting in conjunction of lift power and spacing part 22.
This children trolley also comprises travel rope 3, and the one end of travel rope 3 is fixed on sliding part 15, and the other end of travel rope 3 extends along back stay 121 and extends certain distance along push rod 13 behind the top of pile warp the 3rd axle 18, and its other end is fixed on push rod 13. push rod 13 is inclined upwardly setting from front to back, when children trolley is in expansion state, travel rope 3 is in tensioning state, now being unlocked by the first lock machine structure makes the first lock machine structure be in released state, push rod 13 still can be made under the effect of travel rope 3 to keep state when launching, when children trolley is folding, sliding part 15 upwards slides along back stay 121, travel rope 3 is relaxed, push rod 13 upset downwards under the effect of self gravitation is folding, when children trolley is opened from folded state, sliding part 15 upwards slides along back stay 121, travel rope 3 is tightened up gradually, thus pull push rod 13 upwards turning unfolding.
When this children trolley uses in the deployed state, the first lock machine structure and the 2nd lock machine structure are all in the lock state, thus make this children trolley be in stable expansion state, as depicted in figs. 1 and 2.
When this children trolley is folding, first unlock the first lock machine structure and the 2nd lock machine structure, upwards band 21 is carried in lift afterwards, a bar 14 is overturn backward around the 3rd axle 18, after poppet 12 overturns forward around the 3rd axle 18, seat bar 14 and after poppet 12 are drawn close gradually, before driving in the process, support 11 overturns backward and draws close with after poppet 12, and promote sliding part 15 upwards to slide along back stay 121, sliding part 15 makes travel rope 3 relax gradually when upwards sliding, the tensioning power making travel rope 3 act on push rod 13 is eliminated, push rod 13 just overturns downwards around the first axle 16 under the effect of self gravitation and draws close with after poppet 12, until each rod member of composition stroller frame is drawn close together, finally fold as shown in Figure 4, this children trolley can whole car disposable folding, realize one to carry and namely roll over.
Launch in a folded configuration for ease of this children trolley, this children trolley also comprises sliding bar 41 and is arranged on foot-operated the 42 of sliding bar 41 times ends, sliding part 15 is positioned at the left and right sides of stroller frame 1, sliding bar 41 is arranged on the sliding part 15 of wherein side, sliding bar 41 and back stay 121 extend in the same direction, when sliding part 15 slides on back stay 121, the relative back stay 121 of sliding bar 41 is driven to slide. as a kind of enforcement mode specifically, back stay 121 has pipe chamber, fluting on back stay 121 extends through in this pipe chamber, and the top of sliding bar 41 is located in this pipe chamber and can slide in pipe chamber along the bearing of trend in pipe chamber, and the upper end of sliding bar 41 is fixedly connected with sliding part 15. when this children trolley launches from folded state, step on foot-operated 42, sliding part 15 slide downward on back stay 121 is made by sliding bar 41, and front support 11 is overturn forward around the 4th axle 19 and launches gradually, seat bar 14 upwards overturns around the 3rd axle 18 and launches gradually, sliding part 15 makes travel rope 3 be tightened up gradually on back stay 121 during slide downward, travel rope 3 pulls push rod 13 upwards to overturn around the first axle 16 to launch gradually, position-limit mechanism also it is provided with between push rod 13 and back stay 121, when push rod 13 is upwards turned to the expansion state shown in Fig. 1 and Fig. 2, due to the effect of position-limit mechanism, make push rod 13 can not continue upwards to overturn, then the first lock machine structure and the locking of the 2nd lock machine structure, this children trolley is just disposable is opened to expansion state from folded state.
To sum up, children trolley structure of the present utility model is simple, and children trolley, when folding, only need to upwards lift and carry band and each rod member of composition stroller frame just can be made mutually to overturn draw close so that whole car can disposable fold, it is achieved one carries and namely rolls over; And when this children trolley is opened from folded state, only need to step on foot-operated, the mutual turning unfolding of each rod member of composition stroller frame can be made, whole car can disposable be launched, thus make the folding of this children trolley and open all very convenient, children trolley volume after simultaneously folding is little, is convenient to packaging, transport and stores.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, 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 done according to the utility model spirit change or modify, and all should be encompassed within protection domain of the present utility model.
