[ detailed description ] embodiments

The invention will be further described with reference to the accompanying drawings:

as shown in fig. 1 to 6, the utility model provides a stroller frame can follow the expansion position after the unblock locking Assembly and remove to folding position, stroller frame include: bottom sprag frame 1 that can fold and expand, bottom sprag frame 1 on be connected with and to expand or folding vaulting pole 2 rather than rotating relatively, vaulting pole 2 on be connected with and to expand or folding push rod 3 rather than rotating relatively, vaulting pole 2 on still be connected with handrail assembly 4, just handrail assembly 4 and vaulting pole 2 between be equipped with closure subassembly 5, and closure subassembly 5 is driven the unblock by push rod 3 when push rod 3 is folding relatively vaulting pole 2 rotates and makes handrail assembly 4 rotate relatively by oneself and draw close folding to vaulting pole 2.

The utility model discloses when needs are folding, earlier unblock locking subassembly, locking subassembly unblock back push rod 3 just can relative vaulting pole 2 rotate and to vaulting pole 2 rotate folding, bottom sprag frame 1 also links the unblock this moment, thereby make whole children's shallow frame can be folded, rotate folding in-process to vaulting pole 2 when push rod 3, still with 5 linkage unblocks of locking subassembly, when 5 unblocks of locking subassembly, handrail component 4 just can relative vaulting pole 2 rotate by oneself and to vaulting pole 2 draw close folding, thereby make whole folding process more smooth and easy, it is also more smooth and easy to fold, and the adult need not use push rod 3 roof pressure handrail component 4 when folding children's shallow frame. And the handrail component 4 is arranged on the stay bar 2, so that the size of the joint of the bottom support frame 1 can be reduced, and the occupied space is reduced.

The locking assembly comprises a first locking assembly 61 arranged between the push rod 3 and the support rod 2 and a second locking assembly 62 arranged on the bottom support frame 1, when the first locking assembly 61 is unlocked, the second locking assembly 62 is unlocked in a linkage mode, and the second locking assembly 62 and the first locking assembly 61 are common spline or slide block type child frame locks.

As shown in fig. 2, the locking assembly 5 includes a locking position 51 disposed on the armrest assembly 4, the stay bar 2 is slidably connected with a locking member 52 capable of being locked in or disengaged from the locking position 51, a pull cable 53 capable of disengaging the locking member 52 from the locking position 51 when the push rod 3 is rotated and folded is further disposed between the push rod 3 and the locking member 52, and an elastic element 54 capable of resetting the locking member 52 is further disposed between the locking member 52 and the stay bar 2. When the locking component 5 needs to be unlocked, the first locking component 61 between the support rod 2 and the push rod 3 is unlocked firstly, at the moment, the push rod 3 is rotated to rotate towards the support rod 2 to be close to and folded, when the push rod 3 rotates, the push rod 3 pulls one end of the pull rope 53 to move, the pull rope 53 drives the locking piece 52 to be separated from the locking position 51 after being pulled, when the locking piece 52 is separated from the locking position 51, the locking component 5 is unlocked, and at the moment, the handrail component 4 automatically rotates and folds relative to the support rod 2.

As shown in fig. 2, the middle of the pulling cable 53 is disposed on the stay 2 and deviated from the rotation axis of the pushing rod 3, when the pushing rod 3 rotates relative to the stay 2 to fold, the pulling cable 53 slides around the stay 2 to pull the locking member 52 to disengage from the locking position 51. When the push rod 3 rotates relative to the stay rod 2 to fold, the pull rope 53 slides around the stay rod 2, and the pull rope 53 slides to drive the locking piece 52 to separate from the locking position 51, so that unlocking is more convenient.

As shown in fig. 3, a protrusion 21 is disposed on the stay 2, a groove 211 for sliding the cable 53 is disposed between the protrusion 21 and the stay 2, and a pressing portion 212 capable of pressing against the cable 53 when the cable 53 moves is disposed on the protrusion 21 and at a position eccentric to the rotation shaft of the push rod 3. The groove 211 allows the cable 53 to move, and restricts the cable 53 from moving left and right and shifting. When the pulling cable 53 moves, the pressing portion 212 presses against each other to slide relative to the stay rod 2, and the locking member 52 is pulled to move.

As shown in fig. 3, the pressing portion 212 is a bending piece bent inward. The locking assembly 5 can be used for jacking the inhaul cable 53, and meanwhile, the movable range of the inhaul cable 53 can be limited, so that the inhaul cable is prevented from being separated from the protrusion 21 and the unlocking of the locking assembly 5 cannot be realized.

As shown in fig. 4, the handle assembly 4 includes a handle seat 41 rotatably connected to the push rod 3, a handle rod 42 is connected to the handle seat 41, and the locking portion 51 is disposed on the handle seat 41. The lock position 51 is a slot or the like provided in the armrest base 41.

As shown in fig. 4, the grab bar 42 is detachably attached to the grab seat 41.

As shown in fig. 5 to 6, after the locking assembly 5 is unlocked, the armrest assembly 4 is folded toward the stay bar 2 by its own weight. Realize through self gravity that handrail component 4 rotates to vaulting pole 2 by oneself and folds up after the unblock for whole children's bicycle frame can be more convenient when folding.

As shown in fig. 4, the stay 2 is provided with a relief groove 22 for relieving the armrest unit 4 when the armrest unit 4 is rotated. So that the armrest assembly 4 has a sufficient position to be pivotally folded with respect to the stay 2.
