Baby's umbrella carriage rounded knuckle structure, as shown in Fig. 1, Fig. 3, Fig. 5, it is a kind of articulation structure for the front foot pipe 1 in Baby's umbrella carriage, handle pipe 2 and handrail tube 3 are launched or folded simultaneously simultaneously, and the both sides of a Baby's umbrella carriage often all can possess front foot pipe 1 and handle pipe 2, therefore articulation structure also can arrange identical two groups of structure, the two ends of handrail tube 3 are then installed with two groups of articulation structures respectively.
Described often group articulation structure includes terminal pad 4, lower terminal pad 6, handrail socket 5 and handrail plug 51 etc., the present embodiment, by the inner side as this articulation structure on the left of the view shown in Fig. 2, Fig. 4, Fig. 5, is described explanation as the outside of this articulation structure on the right side of view.
Described upper terminal pad 4 lower end is provided with the lower connection pipe 41 to downward-extension, and upper terminal pad 4 is connected as plug-in mounting with front foot pipe 1 upper end by lower connection pipe 41, then is connected and fixed with rivet 8; Lower terminal pad 6 upper end is provided with the upper connection pipe 61 upwards extended, and lower terminal pad 6 is connected as plug-in mounting with handle pipe 2 lower end by upper connection pipe 61, then is connected and fixed with rivet 8; Handrail socket 5 is arranged on the inner side of lower terminal pad 6, and the inner end surface of handrail socket 5 is provided with slot 53, is provided with the handrail plug 51 that removable jew plug-in mounting connects, then is provided with on handrail plug and connects fixing handrail tube 3 by rivet 8 in this slot.
Described upper terminal pad 4, lower terminal pad 6 and handrail socket 5 are set to the disc structure of same diameter, form concentric through a hinge 14 at the circle centre position of three parts, i.e. axle center place to be articulated and connected simultaneously, again between upper terminal pad 4 inner end surface with lower terminal pad 6 outer face, be respectively equipped with mutually equipped annular groove 15 and bulge loop 13 between lower terminal pad 6 inner end surface and handrail socket 5 outer face, thus make between three, can form mutual rotation.Described upper terminal pad 4 outer face is provided with removable jew and fastens the enclosing cover 7 installed, and hinge 14 end can be closed by this enclosing cover, thus the profile of articulation structure attractive in appearance.
Described lower terminal pad 6 is provided with two slide openings 62, and these two slide openings are symmetrical arranged centered by hinged axle center, and each slide opening 62 is axially through hole, and the mounting structure in each slide opening 62 is all identical.The present embodiment is described for structure set in one of them slide opening 62, it be in slide opening 62, install one can inwardly or outwards as the set pin 9 of axial reciprocating movement, this set pin is straight pin, be set with outside set pin 9 and unlock spring 10, the inner pushing installation of this unblock spring preset in slide opening 62 on shoulder, on the outer shoulder 91 that the outer end pushing installation unlocking spring 10 is preset on set pin 9, therefore set pin 9 is made to possess the propulsive effort of axially outwards movement all the time by the pushing tow unlocking spring 10 under normality; Described set pin 9 outer end is provided with spring bearing 92 as shown in Figure 7, this spring bearing is provided with the inner of retracing spring 11, and the outer end of retracing spring is then provided with the plunger 12 of hat shape, and the head of this plunger is smooth structure.
Described upper terminal pad 4 inner end surface is provided with two convex tendons 42 as shown in Figure 6, each convex tendon is all the echelon form structures be jointly made up of the slope 421 of both sides and the plateau 422 at middle part, and this convex tendon 42 still with hinged axle center for the center of circle is arc-shaped bend; Described two convex tendons 42 form action by upper terminal pad 4 respectively relative to descending terminal pad 6 to rotate with the set pin 9 in two slide openings 62 supporting, namely terminal pad 4 is gone up when lower terminal pad 6 rotates, convex tendon 42 can contact pushing tow plunger 12 and then pushing tow retracing spring 11 and set pin 9 and move inward, or convex tendon 42 departs from the contact with plunger 12, now makes set pin 9 outwards movement by the pushing tow unlocking spring 10; Meanwhile, the slope 421 convex tendon 42 arranged be conveniently plunger 12 head more labour-saving enter convex tendon 42 plateau 422 on or to leave from convex tendon 42.
Described handrail socket 5 outer face is provided with two lockholes 52, it is supporting that these two lockholes also can form action with the set pin 9 in two slide openings 62 when articulation structure carries out launching or folding respectively, namely when articulation structure launches, contact pushing tow plunger 12, retracing spring 11 and set pin 9 move inward by the convex tendon 42 on upper terminal pad 4 inner end surface, correct and enter equipped locking in lockhole on handrail socket 5 outer face 52 in this set pin; When articulation structure folds, the convex tendon 42 on upper terminal pad 4 inner end surface will depart from the contact with plunger 12, now make set pin 9 outwards movement by the pushing tow unlocking spring 10, and the inner of this set pin unlocked from lockhole 52 interior disengaging the handrail socket 5 outer face.
Operating mode of the present utility model is simple, flexible, only need by the cooperation of convex tendon 42 and plunger 12, the inner turnover of set pin 9 can be driven to coordinate lockhole 52 in conjunction with retracing spring 11, the pushing tow that unlocks spring 10 again, thus achieve front foot pipe 1, handle pipe 2 and handrail tube 3 and launch simultaneously or fold simultaneously, greatly facilitate the use of numerous babies father and mother.
