Perambulator is without rocking folding/unfolding joint, as shown in Figure 1 and Figure 2, relate to a kind of for launching to use for baby car joint or the folding retracting mechanism folding, it comprises the upper tube connector 1 and the lower tube connector 2 that are designed to flat tube configuration, on this, the end of tube connector 1 is provided with the upper joint 3 that plug-in mounting connects, and the end of lower tube connector 2 is provided with the hypozygal 4 that plug-in mounting connects.
Described upper joint 3 is to be made up of two hinged disks 32 that be arranged in parallel of the coupling sleeve 31 of upper end and lower end, and coupling sleeve 31 and two hinged disks 32 are made as conjoined structure; Described coupling sleeve 31 is inserted into behind the bottom of tube connector 1, be fixed connection by upper rivet 5 and packing ring 13, in coupling sleeve 31, be provided with along coupling sleeve extend axially and between two hinged disks 32 connect axis hole 312, in two opposed inner walls of this axis hole, be respectively equipped with one along the axially extended gathering sill 311 of coupling sleeve 31; Described hypozygal 4 is to be made up of the hinged disk 42 of upper end and the connecting axle 41 of lower end, and hinged disk 42 is made as conjoined structure with connecting axle 41; Described connecting axle 41 is inserted into behind the upper end of lower tube connector 2, also be fixed connection by lower rivet 7 and packing ring 13, described hinged disk 42 is the circle that diameter is identical with two hinged disks 32, and hinged disk 42 is arranged between two hinged disks 32, through realizing between the two hinged after hard-wired hinged rivet 6, between hinged disk 42 and two hinged disks 32, can realize mutual rotation at concentric place; Meanwhile, upper the rectifying of hinged disk 42, axis hole 312 positions of upper joint 3 are provided with to a lockhole 421.
In the axis hole 312 of described upper joint 3, be provided with locking mechanism, this locking mechanism comprises the joint sleeve 8 that is axially movably arranged on the cylindrical tube shape in axis hole, be connected with drag-line 10 in joint sleeve upper end, this drag-line is hidden and is arranged in tube connector 1, and has realized the release of locking mechanism by drag-line 10; Described joint sleeve 8 lower ends are provided with the female axle 9 of hard-wired ball by connecting pin 11, joint sleeve 8 outer walls are provided with two symmetrically arranged guide pads 82, these two guide pad active mountings are in two gathering sills 311 of axis hole 312 inwalls, therefore can realize the axial orientation motion of joint sleeve 8 in axis hole 312; Described joint sleeve 8 outer walls are also provided with two chutes 81 symmetrical and extend axially setting along joint sleeve, and upper rivet 5 on upper joint 3 passes and is arranged in the chute 81 of joint sleeve 8, therefore it is spacing to have realized the movement travel of joint sleeve 8 in axis hole 312 by chute and upper rivet 5 equipped; The interior flexible member 12 that arranges of described joint sleeve 8, this flexible member upper end pushing tow is passing on the upper rivet 5 of joint sleeve 8, lower end pushing tow is in the upper end of the female axle 9 of ball, therefore be subject to the pushing tow of flexible member 12 to make joint sleeve 8 drive the female axle 9 of ball to be all the state of moving downward under normality, now on this, rivet 5 will be positioned at the top of chute 81.
The female axle 9 of described ball is provided with four radially annular grooves 91 that are axially equally spaced the most successively along the female axle of ball, and every is radially all embedded with ball 92 in annular groove, outside it, supporting ball sleeve 93 is set again, can be used for preventing that ball 92 is from radially coming off in annular groove 91; Simultaneously, the bottom of the female axle 9 of ball is also provided with the fixing ball sleeve of screw 94 93, on the end face of adjacent two ball sleeves, be respectively equipped with engagement gear ring 931, so that connect closely, and ball sleeve 93 can be subject to the axial activity of the female axle 9 of ball and gapless is coincide active mounting axis hole 312 in or the identical active mounting of gapless in lockhole 421.
The present invention has deployed condition and folding collapse state, when deployed condition as shown in Figure 3, Figure 4, its upper and lower tube connector 1,2 is on same level line, joint sleeve 8 is subject to the pushing tow of flexible member 12 to drive the female axle of ball 9 lower ends to be fitted in the lockhole 421 of hypozygal 4 through axis hole 312, now between upper and lower joint, cannot rotate, this state is expansion lock-out state, namely the normal operating condition of perambulator; When folding folding as shown in Figure 5, the elastic band that need pull drag-line 10 and overcome flexible member 12 sleeve pipe 8 that is dynamically connected moves upward, upper rivet 5 will be positioned at chute 81 bottom, moving upward of joint sleeve 8 will drive the female axle 9 of the ball being connected with its lower end also to move upward, thereby make the lockhole 421 interior disengaging of the female axle of ball lower end from hypozygal 4, upper and lower tube connector just can form folded state, namely the folding rounding state of perambulator. In the course of action of the above-mentioned deployed condition of formation or folding collapse state, form the gapless active mounting that coincide by the many groups of balls that match 92 and ball sleeve 93 with axis hole 312 and lockhole 421 on hypozygal 4 in upper joint 3, therefore bring more stable and reliable serviceability for the expansion of whole perambulator is used and fold to fold.
