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.
stroller frame comprises the two groups of side stands be symmetrical set, and often organizes side stand and comprises front frame 3, pulling handle rod 4, after poppet 5, front stall bar 6, back seat bar 7, first connecting rod 8, second connecting rod 9 and sliding part 10.Front component 1 is arranged on the bottom of front frame 3, and wheel assembly 2 is arranged on the bottom of after poppet 5.Be provided with between the leading section of two back seat bars 7 of the left and right sides and separate lock strap 11.
the upper end of pulling handle rod 4 and after poppet 5 is rotated by the 3rd rotating shaft 14 and is connected; The leading section of front stall bar 6 and front frame 3 rotated by the 5th rotating shaft 16 be connected, the leading section of rearward end and back seat bar 7 rotated by the 6th rotating shaft 17 and is connected; The both ends of second connecting rod 9 to rotate with after poppet 5 and back seat bar 7 respectively by the first rotating shaft 12 and the second rotating shaft 13 and are connected; Sliding part 10 is slidably arranged on after poppet 5 along the length direction of after poppet 5, and in the present embodiment, sliding part 10 is sliding sleeve, and sliding sleeve is set on after poppet 5 slidably.
the leading section of pulling handle rod 4 and the upper end of front frame 3 are rotated by the 4th rotating shaft 15 and are connected, and the upper end of first connecting rod 8 and pulling handle rod 4 and/or front frame 3 are rotated by the 9th rotating shaft and be connected.In the present embodiment, as shown in Figures 1 to 4, upper end three's coaxial rotation of the leading section of pulling handle rod 4, the upper end of front frame 3, first connecting rod 8 connects, and namely the 4th rotating shaft 15 and the 9th rotating shaft are same axis.When stroller frame is in deployed condition, front frame 3 and pulling handle rod 4 are roughly on same straight line.
back seat bar 7 and sliding part 10 are rotated by the 7th rotating shaft 18 and are connected, the bottom of first connecting rod 8 and sliding part 10 are rotated by the 8th rotating shaft and are connected, in the present embodiment, as shown in Figures 1 to 4, bottom, the sliding part 10 three coaxial rotation of back seat bar 7, first connecting rod 8 connect, and namely the 7th rotating shaft 18 and the 8th rotating shaft are same axis.
due in this enforcement, 4th rotating shaft 15 and the 9th rotating shaft are same axis, 7th rotating shaft 18 and the 8th rotating shaft are same axis, therefore, only the 4th rotating shaft 15 and the 7th rotating shaft 18 are marked in the drawings and in which, also the 4th rotating shaft 15 and the 9th rotating shaft are merged below and be described as the 4th rotating shaft the 15, seven rotating shaft 18 and the 8th rotating shaft and merge and be described as the 7th rotating shaft 18.
first rotating shaft 12 is positioned at the below of sliding part 10, and the second rotating shaft 13 is positioned at the rear being rotationally connected point (i.e. the 7th rotating shaft 18) of back seat bar 7 and sliding part 10.When stroller frame is in deployed condition, 4th rotating shaft 15 is positioned at the front lower place of the 3rd rotating shaft 14, the back upper place of the 5th rotating shaft 16, the top of the 6th rotating shaft 17, the front upper place of the 7th rotating shaft 18,7th rotating shaft 18 is positioned at the rear of the 6th rotating shaft 17, roughly on the same line, the 5th rotating shaft 16, the 6th rotating shaft 17, the 7th rotating shaft 18, second rotating shaft 13 are roughly on the same line for 3rd rotating shaft 14, the 4th rotating shaft 15 and the 5th rotating shaft 16.The axial line of the first rotating shaft 12 and the second rotating shaft 13, the 3rd rotating shaft 14, the 4th rotating shaft 15, the 5th rotating shaft 16, the 6th rotating shaft 17, the 7th rotating shaft 18 is parallel to each other and left and right directions along children trolley extends.
lockout mechanism is arranged between sliding part 10 and after poppet 5 for both relatively being locked.The concrete structure of lockout mechanism is not the emphasis of the utility model protection, as long as can realize locking relative with after poppet 5 for sliding part 10, such as, can adopt following structure: the cooperation locking etc. of locking piece and locking part.
principle of work: when children trolley is changed from deployed condition to folded state by needs, unlock lock mechanism, upwards pull and separate lock strap 11, the leading section of back seat bar 7 and the rearward end of front stall bar 6 is driven upwards to rotate, front frame 3 is driven and rotates towards after poppet 5, sliding part 10 is driven upward sliding, and pulling handle rod 4 rotates under gravity near after poppet 5, completes children trolley from deployed condition to the conversion of folded state.
when children trolley is changed from folded state to deployed condition by needs, upwards pull pulling handle rod 4, the rearward end of front stall bar 6 and the leading section of back seat bar 7 rotate, front frame 3 moves towards the direction away from after poppet 5, sliding part 10 slide downward, lockout mechanism relocks, and completes children trolley from folded state to the conversion of deployed condition.
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.
