Detailed description of the invention
Below in conjunction with above-mentioned accompanying drawing and adopt specific embodiment to be described in detail again the utility model.
As shown in Fig. 1 ~ Fig. 5,1. handle pipe, 2. adapting pipe, 3. go up fixed cover, 31. long sliding holes, 4. descend fixed cover, 5. fold button, 6. locking pin, 7. fold stay cord, 8. go up stay hook, 81. fixed plates, 82. slotted holes, 9. descend stay hook, 91. draw-in grooves, 10. retracing spring, 11. guide chutes, 12. stick harnesses, 13. lower fixed seats.
Baby carriage armrest pipe retracting mechanism, as shown in Fig. 1 ~ Fig. 3, it is a kind of rod connection structure being widely used on baby carriage armrest pipe, can launch to use to facilitate promote or pull perambulator to move, also can fold and fold to dwindle packaging volume, be convenient to transport and carry.
Described handrail tube is made up of with the adapting pipe 2 that is connected to handle pipe both ends the handle pipe 1 that is inverse u shape, the connection structure of this handle pipe 1 and two adapting pipes 2 is all identical, therefore the present embodiment is only described in detail with the structure that adapting pipe 2 is connected with the handle pipe 1 of a side wherein.
The front side, " U " type bottom of described handle pipe 1 be provided with expose installation fold button 5, this folds button and adopts common push type structure on baby's perambulator, is no longer repeated in this description herein.
In described handle pipe 1, be provided with and fold stay cord 7, this folds stay cord upper end and is connected to and folds on button 5, is formed pulling action therefore fold button by pressure energy; Handle pipe 1 bottom is provided with fixed cover 3, and on this, fixed cover is fixedly connected in handle pipe 1 by many rivets, is provided with and hides upper stay hook 8 and the retracing spring 10 installed in upper fixed cover 3.
Described upper stay hook 8 and the mounting means of retracing spring 10 are: handle pipe 1 bottom is provided with one along the axially extended guide chute 11 of handle pipe, upper stay hook 8 is arranged in this guide chute 11 and carries out slippage, in order to prevent that the rivet that the slipping motion of upper stay hook 8 is fixedly connected in handle pipe 1 from stopping, at upper stay hook 8 rear sides and be positioned at and be also provided with the slotted hole 82 passing for rivet on the upper stay hook of handle pipe 1; Upper stay hook front side is provided with stretches out the disjunctor fixed plate 81 that the guide chute 11 of handle pipe 1 exposes, on fixed plate, lock pin 6 through one, these locking pin two ends are passed respectively and are arranged in the default long sliding hole 31 in fixed cover 3 two sides, therefore in the time that upper stay hook 8 carries out upper and lower slippage along guide chute 11, can drive locking pin 6 also to carry out upper and lower slippage in long sliding hole 31; Upper stay hook 8 upper ends are connected with the lower end that folds stay cord 7, are driven slippage therefore fold stay cord.Between the described retracing spring 10 two ends fixed plate 81 that pushing tow exposes at upper stay hook 8 respectively and upper fixed cover 3 inwalls, therefore can make stay hook 8 possess all the time a propulsive effort for operation downwards under the elastic force of retracing spring 10 promotes.
Described adapting pipe 2 upper ends are provided with lower fixed seat 13 and are sleeved on the lower fixed cover 4 outside lower fixed seat; Described lower fixed seat 13 is fixed in adapting pipe 2 by rivet, in adapting pipe upper end, plug is equipped with lower stay hook 9, its plug assembling structure is: lower stay hook 9 is provided with identical two of structure, these two lower stay hooks are fixedly connected on respectively the both sides of a stick harness 12, and by stick harness, two lower stay hook 9 fixed plugs are contained in adapting pipe 2 upper ends, each lower stay hook 9 upper ends are exposed and are provided with draw-in groove 91, two draw-in grooves are just in time equipped with and engage with locking pin 6, thereby form locking between the two; Described handle pipe 1 lower end is passed down through fixed cover 3 and is articulated and connected on lower fixed cover 4, this handle pipe 1 is adjacent setting with adapting pipe 2, and be positioned at adapting pipe rear side, therefore handle pipe 1 can relatively be descended fixed cover 4 to form and fold rotation relation, and lower fixed cover 4 can be hidden the various parts that are arranged on adapting pipe 2 upper ends, also can form and coordinate with upper fixed cover 3, with the profile that folds assembly attractive in appearance.
The utility model is divided into and launches use state and folding collapse state: while launching to use, as shown in Figure 4, only need conter clockwise upwards to rotate handle pipe 1, and drive locking pin 6 to be fastened in the draw-in groove 91 of lower stay hook 9 to lock; When folding folding as shown in Figure 5, must press and fold button 5 and drive upper stay hook 8 to move up along guide chute 11 through folding stay cord 7, and then drive the draw-in groove 91 interior disengaging of locking pin 6 from lower stay hook 9, now only need pull handle pipe 1 downwards can fold in relative adapting pipe 2.
