Detailed description of the invention
As Fig. 1 is to shown in 5, according to the present embodiment
Children trolley, it includes having the stroller frame 1 of deployed condition and folded state, front component 2 and wheel assembly 3, seat pocket interface 4 and stroller frame 1 is locked in the locking device of deployed condition.
Stroller frame 1 includes being positioned at the side stand that both sides are symmetrical.The side stand of every side includes that rotate with the rearward end of bottom bar 10 rear pole 11 that is connected, bottom of the bottom bar 10 extended along the longitudinal direction, bottom rotates with the upper end of rear pole 11 push rod 12 being connected.
Front component 2 includes front-wheel 20 and front-wheel joint 21, and wheel assembly 3 includes trailing wheel 30 and trailing wheel joint 31, and wherein front-wheel joint 21 and trailing wheel joint 31 rotate be connected with leading section and the rearward end of bottom bar 10 respectively.Concrete, in bottom bar 10, it is provided with the length direction along bottom bar 10 extends and can fixing with the both ends of rotating shaft a respectively around the rotating shaft a of own axis, front-wheel joint 21 and trailing wheel joint 31 be connected.It addition, be provided with gathering sill b in the inner side of bottom bar 10, on rotating shaft a, the position at corresponding gathering sill b has protruding c, protruding c to insert in gathering sill b, and the two coordinates the rotation of countershaft a to guide and limit.So, the front component 2 and the wheel assembly 3 that are positioned at homonymy synchronize to carry out relative to the rotation of bottom bar 10, and all make one-directional rotation.
In this example, locking device includes the second lock cell being used for the two relatively being locked between the first lock cell, the upper end being arranged on rear pole 11 and the bottom of push rod 12 locked that rear pole 11 is relative with wheel assembly 3.By hauling rope linkage of unlocking between second lock cell and the first lock cell.This locking device is after operation unlock piece, and the second lock cell and the first lock cell unlock simultaneously, and the stroller frame after unblock can be folded.
Concrete, the second lock cell includes the locking piece 5(electric bell part being arranged between push rod 12 bottom and rear pole 11 upper end), be arranged on push rod 12 unlock piece 6 making locking piece 5 unlock.First lock cell includes the locked groove 7 being arranged on inside trailing wheel joint 21, coordinates the dead bolt 8 of locking with locked groove 7.Rear pole 11 has below bottom bar 10 the pin portion 9 extending and having breach d, and dead bolt 8 is arranged in this pin portion 9, and is fastened in locked groove 7 via breach d, it is achieved locking.Meanwhile, dead bolt 8 is also connected by hauling rope with locking piece 5, and when locking piece 5 unlocks, dead bolt 8, under the drive of locking piece 5, departs from from locked groove 7 and unlocks.
Further, stroller frame also includes the first connecting rod 13 between both sides rear pole 11 and the second connecting rod between both sides bottom bar 10 14, wherein the bottom, pin portion 9 of both sides is connected by first connecting rod 13, second connecting rod 14 is positioned at the middle part of bottom bar 10, for being connected by the bottom bar 10 of both sides.First connecting rod 13 is additionally provided with braking mechanism i(conventional design, does not do tired stating at this).
In addition, push rod 12 in this example self can telescopic adjustment, concrete include that bottom is connected to the first pole 120 that rear pole 11 upper end connects, wherein can be additionally provided with, along flexible the second pole 121 being arranged in the first pole 120 of the bearing of trend of the first pole 120, for the handle 122 being connected the second pole 121 upper end of both sides, the control piece e that can control the second pole 121 relative telescopic in the first pole 120 on handle 122.
The concrete side the first pole 120 is provided with the round f arranged along the first pole 120 bearing of trend, opposite side the second pole 121 is provided with the locking bolt g that can stretch and coordinate with round f, and the control knob h being arranged on handle 122 and the pull rope for being connected with locking bolt g by control knob h.
The present embodiment children trolley folding process is as follows: operation control piece, the second pole making push rod is contracted in the first pole, the locking piece (electric bell) of both sides is unlocked by the unlock piece the most simultaneously operating both sides, now, first lock cell is also with unblock, then push rod and rear pole it are pressed downward against, push rod and rear pole is made to draw close to bottom bar, thus realize the folding of vehicle frame, and along with the folding of rear pole, its pin portion departs from locking with wheel assembly, operable wheel assembly, itself and front component is made to synchronize inside folding in the accommodation space between the bottom bar of both sides, thus complete the folding of car load.
It is as follows that the present embodiment children trolley launches process: front component and wheel assembly is produced from accommodation space, mention push rod then up, the pin portion of the bottom of rear pole inserts between the wheel assembly of both sides, until dead bolt is fastened in locked groove, rotating shaft cannot be rotated, so that wheel assembly and the metastable expansion of front component, then locked relative with rear pole for push rod by locking piece (electric bell), last operation control piece, regulation push rod, to appropriate length, i.e. completes the expansion of car load.
Above the present invention is described in detail; its object is to allow the personage being familiar with this art will appreciate that present disclosure and to be carried out; can not limit the scope of the invention with this; all equivalence changes made according to the spirit of the present invention or modification, all should contain within the scope of the present invention。
