Detailed description of the invention
as shown in the drawings, a kind of children trolley, comprise can fold stroller frame, front component 1, wheel assembly 2, stroller frame can be locked in the lockout mechanism of deployed condition.
the front-wheel support 4 that stroller frame comprises pulling handle rod 3, rearward end and the leading section of pulling handle rod 3 rotate to be connected, upper end and the rearward end of front-wheel support 4 rotate the rear wheel support 5 be connected, stroller frame also comprises and extends the bottom supporting rod 7 be connected, the sliding part 8 be slidably arranged in along the length direction of bottom supporting rod 7 on bottom supporting rod 7 and leading section and front-wheel support 4 rotate along the longitudinal direction, and sliding part 8 rotates with rear wheel support 5 and is connected.The rearward end of bottom supporting rod 7 is free end, and the rearward end mentioning bottom supporting rod 7 can complete the folding of stroller frame.In the present embodiment, sliding part 8 is sliding sleeve, and during vehicle frame folding, sliding sleeve can slide on bottom supporting rod 7.
rear wheel support 5 comprises the first rear pole 6 and the second rear pole 19, first rear pole 6 and intersects with the second rear pole 19 and arrange and be connected rotatedly at infall.
sliding part 8 is rotatably connected on the infall of the first rear pole 6 and the second rear pole 19.First rear pole 6 and the second rear pole 19 about the first rear pole 6 and the second rear pole 19 infall in a center of symmetry.First rear pole 6 and the second rear pole 19 all roughly S-type.
be in particular, sliding part 8 is formed with outward extending lug boss 16, the infall of the first rear pole 6 and the second rear pole 19 is provided with connecting portion 17, and the first rear pole 6 and the second rear pole 19 are rotated by the first pivot and be connected, and connecting portion 17 and the first pivot are fixedly connected.Lug boss 16 rotates with connecting portion 17 and is connected, and is in particular, and connecting portion 17 and lug boss 16 are rotated by the second pivot 18 and be connected.The direction of axis line of the first pivot is vertical with the direction of axis line of the second pivot 18, and the axial line of the second pivot 18 extends along the left and right directions of children trolley.
front-wheel support 4 comprises and is positioned at the stroller frame left and right sides and leading section is formed with first front strut 9 on the first inclined-plane and the second front strut 20 respectively, extends and both ends are formed with first cross bar 10 on the second inclined-plane respectively along the left and right directions of children trolley, and the first inclined-plane of every side and the second inclined-plane are coordinated by the rotating shaft 11 simultaneously through the first inclined-plane and the second inclined-plane and rotate thus front-wheel support 4 can laterally be drawn close.
two the second inclined-planes are outward-dipping all from bottom to top, the equal out of plumb of rotating shaft 11 and the first inclined-plane and the second inclined-plane.
pulling handle rod 3 comprises the first push rod 12 of being positioned at the stroller frame left and right sides and the second push rod 13, end and the first push rod 12 the rotate the other end of the 3rd cross bar 15, second cross bar 14 be connected of the second cross bar 14, end of being connected and the second push rod 13 that rotates and rotates with the other end of the 3rd cross bar 15 and be connected.
front component 1 is arranged on the leading section of front-wheel support 4, wheel assembly 2 is arranged on the bottom of rear wheel support 5, be in particular, front component 1 is arranged on the below of the first cross bar 10, and wheel assembly 2 comprises the left rear wheel of the bottom being arranged on the first rear pole 6 and is arranged on the off hind wheel of bottom of the second rear pole 19.
first push rod 12 rotates with front-wheel support 4 respectively with the leading section of the second push rod 13 and is connected, and the rearward end of the first front strut 9 rotates with pulling handle rod 3 respectively with the rearward end of the second front strut 20 and is connected.Be in particular, the leading section of the first push rod 12 rotates with the rearward end of the first front strut 9 and is connected, and the leading section of the second push rod 13 rotates with the rearward end of the second front strut 20 and is connected.
the upper end of the first rear pole 6 and the upper end of the second rear pole 19 rotate with the first front strut 9 and the second front strut 20 respectively and are connected.The leading section of bottom supporting rod 7 rotates with the first cross bar 10 and is connected.
lockout mechanism comprises can by sliding part 8 and the first rear pole 6 sliding part locked component of locking relative to the second rear pole 19.This sliding part 8 locked component is not the emphasis of the utility model protection, as long as can realize locking relative with the second rear pole 19 to sliding part 8 and the first rear pole 6, such as adopts locked groove lock pin to coordinate locking etc.
folding principle: first the junction of the second cross bar 14 and the 3rd cross bar 15 is unlocked, then turning over forward pulling handle rod 3 makes it draw close to front-wheel support 4, then sliding part locked component is unlocked, carry the rearward end of bottom supporting rod 7, under gravity, sliding part 8 along bottom supporting rod 7 forward slip, while driving rear wheel support 5 forward slip, drive the first rear pole 6 and the second rear pole 19 mutually to draw close with pulling handle rod 3 and front-wheel support 4, realize the longitudinal folding of stroller frame.Described front-wheel support 4 is in the above-mentioned process of mutually drawing close, because the first front strut 9 rotates relative to the second inclined-plane of the first cross bar 10 with the first inclined-plane of the second front strut 20, thus realize that the first front strut 9 is relative with the second front strut 20 to be drawn close, namely complete the laterally folded of stroller frame.Of the present utility model stroller frame can realize longitudinal folding and laterally folded, but be not limited to above-mentioned while realize longitudinal folding laterally folded, also can first realize longitudinal folding, rear realize laterally folded.
as mentioned above, we are illustrated according to aim of the present utility model completely, but the utility model is not limited to above-described embodiment and implementation method.Different changes and enforcement is carried out in the scope that the practitioner of correlative technology field can permit at technological thought of the present utility model.
