Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of infant pushchair of being convenient to folding, comprises forward foot in a step assembly 2 and handle assembly 1, and is connected to the folding joint 3 between forward foot in a step assembly 2 and handle assembly 2, and folding joint 3 inner sides are also connected with handrail 4.Keep handle assembly 1 motionless, by folding joint, folding forward foot in a step assembly 2 and handrail 4 simultaneously, coordinates other to connect joint and can realize whole infant pushchair folding.
As shown in Figure 3 and Figure 4, folding joint 3 comprises the handgrip group joint 31, forward foot in a step group joint 32 and the armrest seat 33 that are hinged.Handgrip group joint 31 has axial centre hole 31a, and forward foot in a step group joint 32 has axial centre hole 32a, and armrest seat 33 has axial centre hole 33a, and rotating shaft 35 is located in centre hole 31a, 32a and 33a simultaneously.Forward foot in a step group joint 32 is provided with the first arc groove 321 taking rotating shaft 35 as the center of circle, and handgrip group joint 31 is provided with the second arc groove 311 taking rotating shaft 35 as the center of circle.The first arc groove 321 equates with the radius of the second arc groove 311, and while making to turn an angle, the first arc groove 321 and the second arc groove 311 have intersection.Angle orientation rivet 36 for the fixing anglec of rotation is located in the first arc groove 321 and the second arc groove 311 simultaneously, particularly, is to be located in the cavity of the first arc groove 321 and the second arc groove 311 intersection formation.
The rotation in handgrip group joint 3 and location are the first arc groove 321, the second arc groove 311 and rotating shaft, and complete under the common cooperation of angle orientation rivet 36.Infant pushchair is in the time of extended configuration, and handgrip group joint 31 and forward foot in a step group joint 32 are substantially aligned, and the first arc groove 321 and the second arc groove 311 only partially overlap, and intersection only can be held angle orientation rivet 36.
The outside in handgrip group joint 3 is provided with joint enclosing cover 37, and armrest seat 33 is positioned at the inner side in handgrip group joint 3.The position that armrest seat 33 is corresponding with the first arc groove 321 is also provided with angle orientation hole 331, angle orientation rivet 36 is also located in angle orientation hole 331 near one end of folding joint 3 inner sides, makes armrest seat 33 can follow angle orientation rivet 36 and 35 rotates around the shaft.
Armrest seat 33 sidewalls are provided with deck 332, and deck 332 has the flange for clamping, and the draw-in groove 41 mating with deck 332 is established in handrail 4 ends.The middle part of deck 332 and draw-in groove 41 is equipped with lock hole, snap lock rationed marketing 34 is installed in the lock hole of deck 332, snap lock rationed marketing 34 one end are press-side, the other end is fixed end, fixed end is provided with the gib block 341 of end band claw, and the lock hole bottom of deck 332 is provided with the bullport 332 mating with gib block 341.Snap lock rationed marketing 34 is provided with spring, ensures when mounted, and the press-side of snap lock rationed marketing 34 protrudes the lock hole of deck 332 and stretches in the lock hole of draw-in groove 41.Draw-in groove 41 be locked as through hole, when hole dismounting handrail 4, press snap lock rationed marketing 34 until depart from the lock hole of draw-in groove 41, handrail 4 can be extracted.Press-side also has the lead-in chamfered of being convenient to draw-in groove and deck installation.
As shown in Figure 5, in the time that folding joint launches, the coincidence position of the first arc groove and the second arc groove only can hold angle orientation rivet, gradually folding joint is folded, the intersection of the first arc groove and the second arc groove increases, angle orientation rivet rests on the end of the first arc groove, until the end of the second arc groove overlaps with the end of the first arc groove, the second arc groove drives angle orientation rivet to move until folding joint forms folding state.
The angle that folding joint can rotate is central angle and central angle sum corresponding to the second arc groove that the first arc groove is corresponding.The central angle central angle corresponding with the second arc groove that the first arc groove is corresponding equates, is 80-85 °.The central angle sum that the central angle that the first arc groove is corresponding and the second arc groove are corresponding is 160-170 °, because also have handrail between handgrip group joint and forward foot in a step joint, also leaves the angular region of 10-20 ° between handgrip group joint and forward foot in a step joint in the time of folding.
The angle that angle orientation rivet rotates around the axis equals the angle of the central angle that the first arc groove is corresponding, and therefore handrail equals with the angle of handle assembly the central angle that the first arc groove is corresponding.
The foregoing is only preferred embodiment of the present utility model; not thereby limit scope of patent protection of the present utility model; the equivalent structure transformation that every utilization the utility model specification sheets and accompanying drawing content are done; directly or indirectly be used in other relevant technical fields, be all in like manner included in protection domain of the present utility model.
