Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model detailed description of the invention is described。
As it is shown in figure 1, a kind of telescopic folding baby stroller, including front foot lever 10, rear foot lever 20, pushing hands bar and seat frame 50；Pushing hands bar includes the mutually folding upper pushing hands bar 30 coordinated and lower pushing hands bar 40, between be provided with to be controlled by and control switch 31 and the pushing hands lever switch 70 in big joint 60 can be unlocked；The bottom of lower pushing hands bar 40 is provided with a pair big joint 60 that transverse axis 80 connects, and big joint 60 includes fixing joint and the rotary joint coordinated with fixing joint coaxial rotation；Front foot lever 10 slides and is located in fixing joint, and rear foot lever 20 slides and is located in rotary joint；Seat frame 50 is connected with fixing joint and front foot lever 10 respectively by connecting rod 51；Between upper pushing hands bar 30 and lower pushing hands bar 40。
As shown in Figures 2 and 3, pushing hands lever switch is followed successively by upper pushing hands bar joint 71 by left-to-right, unlocks throw-out collar 72, lock gear 73, big knuckle lock 74, lower pushing hands bar joint 75。Wherein go up pushing hands bar joint 71 and lower pushing hands bar joint 75 to be fixed in pushing hands lever switch by above-mentioned parts for right section 752 by pushing hands lever switch axis left section 711 and the pushing hands lever switch axis coordinated。
Unlock throw-out collar 72 to be connected with controlling switch by the hauling rope connected on hauling rope hole 722。Without, under External Force Acting, unlocking throw-out collar 72 and fitted with the inclined-plane tooth 713 in upper pushing hands bar joint 71 by the inclined-plane tooth 721 that unlocks of self。Because unlocking the thickness thickness less than the locking teeth 712 in upper pushing hands bar joint 71 of throw-out collar 72, so, it is pressed on the lock gear 73 unlocked on throw-out collar 72 to engage with the locking teeth 712 in upper pushing hands bar joint 71, and the locking teeth 751 in lower pushing hands bar joint remains and the engaging of lock gear 73, in this case, upper pushing hands bar joint 71 and lower pushing hands bar joint 75 keep locking, it is impossible to rotate。When triggering control switch, when hauling rope drives the hauling rope hole 722 unlocking throw-out collar 72 to move upward, by unlocking the unblock inclined-plane tooth 721 of throw-out collar 72 self and coordinating of the inclined-plane tooth 713 in upper pushing hands bar joint 71, unlock throw-out collar 72 and push down on hand lever joint 75 axially-movable, lock gear 73 is released the region engaged with the locking teeth 712 in upper pushing hands bar joint 71, upper pushing hands bar joint 71 and lower pushing hands bar joint 75 along gathering sill 731 unlock。
When upper pushing hands bar is centered by pushing hands lever switch, push down on hand lever when drawing close, big joint in upper pushing hands bar joint 71 unlocks tooth 713 can stir the locking face 741 of high point joint lock 74 by unlocking gear, pulls hauling rope to unlock big joint thereby through the hauling rope connected on hauling rope hole 742。
As shown in Figure 4, the parts in big joint are followed successively by side lid 61, rotary joint 62, rear follower block 63, rear follower block set 64, front follower block 65, axial stretching pin 66, guide 67, hauling rope steering block 68 and fixing joint 69 from left to right。Wherein rotary joint 62 is provided with rear foot lever insertion hole 622, coordinates the pin-and-hole 624 of axial telescopic pin 66, rear foot lever to stretch out hole 623 and the guiding shaft shoulder 621；Rear follower block set 64 is provided with mean for the arcuate groove that after back leg bar connects through rear follower block set 64, the through hole 641 of follower block 63 coordinates with front follower block 65 and the spacing shaft shoulder 642 coordinated with front follower block 65；Front follower block 65 is provided with mean for the lower pushing hands rod through-hole 652 of lower pushing hands bar traverse overlap inserted link 651 that on 64, arcuate groove coordinates with rear follower block and overlap the spacing flanging 652 that the 64 upper limit shaft shoulders 642 coordinate with rear follower block；Axial stretching pin 66 is provided with the towing pad 661 for fixed traction rope,；Guide 67 is provided with the passage 671 for installing axial stretching pin 66 and installs hauling rope steering block 68 installed surface 672；The chamfering for being transformed in horizontal direction by the hauling rope on vertical direction hauling rope it is provided with in hauling rope steering block 68；Fixing joint 69 is provided with the axis hole 693 of fixing transverse axis, wears the forward foot in a step through hole 692 of front foot lever, wears the lower pushing hands rod through-hole 691 of lower pushing hands bar。
As shown in Figure 5, view direction shown in figure is towards the foreleg bar 10 on right side and rear push-rod 20 and along the figure seen by the direction of transverse axis 80, the wherein middle part of first connecting rod 511 hinged seat chair frame 50 and fixing joint 69, for avoiding interference with, first connecting rod 511 is designed as J-shaped；Second connecting rod 512 is connected to seat frame 50 by two fixing points, and the other end is fixed in front follower block 65。
Work process is as follows:
When needs are folding, as shown in Fig. 1～Fig. 8, trigger and control switch 31, when hauling rope drives the hauling rope hole 722 unlocking throw-out collar 72 to move upward, by unlocking the unblock inclined-plane tooth 721 of throw-out collar 72 self and coordinating of the inclined-plane tooth 713 in upper pushing hands bar joint 71, unlock throw-out collar 72 and push down on hand lever joint 75 axially-movable, lock gear 73 is released along gathering sill 731 region engaged with the locking teeth 712 in upper pushing hands bar joint 71, upper pushing hands bar joint 71 and lower pushing hands bar joint 75 and unlocks。Now drive upper pushing hands bar 30 centered by pushing hands lever switch 70, push down on hand lever 40 when drawing close, big joint in upper pushing hands bar joint 71 unlocks tooth 713 can stir the locking face 741 of high point joint lock 74 by unlocking gear, hauling rope is pulled to unlock the axial limiting pin 66 in big joint 60 thereby through hauling rope hole 742, now rotary joint 62 can centered by transverse axis 80, rotate freely with arcuate groove for scope, when manually back leg bar 20 is rotated to when reclining with foreleg bar 10 (such as Fig. 7), lower pushing hands bar 40, back leg bar 20 is with foreleg bar 10 in the same direction, the trailing edge of seat frame 50 is done in now lift, under the drive of connecting rod 51, foreleg bar 10 and back leg bar 20 is driven to be upward through fixing joint 69 by slider-crank mechanism, overall structure is received in supreme pushing hands bar 30。
Launch reverse operating during baby stroller。
The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, for a person skilled in the art, this utility model can have various modifications and variations。All within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model。
