Abstract
The invention discloses a reversing child stroller. A seat pocket rod is connected with a supporting rod in a rotatable mode, and a first locking device and a second locking device used for limiting relative positions of the seat pocket rod and the supporting rod are arranged between the seat pocket rod and the supporting rod. A push rod is connected with a seat pocket rod in a rotatable mode and is respectively connected with the first locking device and a second locking device. When the push rod is located at a third working position and the seat pocket rod is located at a first working position, the first locking device is in a locking state, and the second locking device is in an unlocking state. When the push rod rotates to be at a fourth working position and the seat pocket rod is located at the first working position, or when the push rod rotates to be at the third working position and the seat pocket rod is located at a second working position, the first locking device and the second locking device are both in the unlocking state. When the push rod is located at the fourth working position and the seat pocket rod rotates to be at the second working position, the first locking device is in the unlocking state, and the second locking device is in the locking state. Only the push rod needs to be operated, and then mutual steering of the front and the back of a seat pocket can be achieved easily.
Description
Technical field
the present invention relates to a kind of commutation children trolley.
Background technology
children trolley generally comprises that underframe, bottom that wheel is installed are connected to strut bar on underframe, the top that is connected to strut bar is for the seat pocket bar of mount pad pocket and connect the push rod on present pocket bar, existing switchable children trolley, its structure is that push rod can be connected front and back rotationally with seat pocket bar, by rotating push-rod, carries out the purpose that front and back position converts to realize the go-cart commutation.But this reversing mode is very single, and can only convert the position of push rod, can not change a pocket towards.
Summary of the invention
in order to address the above problem, the object of the present invention is to provide a kind of be convertible push rod position again convertible seat pocket towards the commutation children trolley.
in order to reach above purpose, the technical solution used in the present invention is: a kind of commutation children trolley, it comprises that bottom is equipped with the underframe of wheel, be connected to the strut bar on underframe, be connected to the seat pocket bar on strut bar, the push rod that two ends are connected with the two ends of seat pocket bar respectively, the middle part of seat pocket bar can be connected to rotationally strut bar top and at least have the first and second two control positioies around the strut bar axial line, be provided with the first blocking device and the second blocking device that limits the two relative position between seat pocket bar and strut bar, push rod can before and after connect rotationally on present pocket bar and at least there are the third and fourth two control positioies, and push rod is connected with the second blocking device with the first blocking device respectively, when push rod at the 3rd control position and seat pocket bar during at the first control position, the first blocking device is in the lock state, the second blocking device is in released state, when push rod turns to the 4th control position and seat pocket bar at the first control position, the first blocking device and the second blocking device are all in released state, when push rod, when the 4th control position and a seat pocket bar turn to the second control position, the first blocking device is in released state, and the second blocking device is in the lock state, when push rod turns to the 3rd control position and seat pocket bar at the second control position, the first blocking device and the second blocking device are all in released state.The 3rd control position of push rod and the 4th control position are to define according to the relative position between push rod and seat pocket bar, and in whole commutation process, the control position of push rod has nothing to do with the relative position between itself and his parts; And the first control position and second control position of seat pocket bar are to define according to the relative position between seat pocket bar and strut bar.
further, be provided with draw-in groove on strut bar, the first blocking device comprise arrange on present pocket bar and with the first lock pin, an end of draw-in groove clamping separatably the first trailing cable that the other end is connected with push rod by the first operating mechanism that is connected with the first lock pin; The second blocking device comprises and arranges on present pocket bar and pass through the second trailing cable of second operation machine structure and push rod with the second lock pin, an end of the draw-in groove clamping separatably other end that is connected with lock pin; When push rod at the 3rd control position and seat pocket bar during at the first control position, the first lock pin and the clamping of draw-in groove phase, the second lock pin and draw-in groove are separated; When push rod turns to the 4th control position and seat pocket bar at the first control position, the first lock pin and the second lock pin all are separated with draw-in groove; When push rod, when the 4th control position and a seat pocket bar turn to the second control position, the first lock pin draw-in groove is separated, the second lock pin and the clamping of draw-in groove phase; When push rod turns to the 3rd control position and seat pocket bar at the second control position, the first lock pin and the second lock pin all are separated with draw-in groove.
further, the first lock pin arranges a side of the pivot center of present pocket bar, and the second lock pin arranges the opposite side of the pivot center of present pocket bar.
further, when push rod, during at the 4th control position, the first trailing cable applies the power that makes the first lock pin exit draw-in groove to the first lock pin.
further, when push rod, during at the 3rd control position, the second trailing cable applies the power that makes the second lock pin exit draw-in groove to the second lock pin.
further, the first operating mechanism comprises and is arranged on push rod and the STATEMENT OF FEDERALLY SPONSORED be connected with the other end of the first trailing cable, and the junction of the first trailing cable on STATEMENT OF FEDERALLY SPONSORED and the pivot center of push rod have certain distance.
