The specific embodiment
Shown in Fig. 1, Fig. 2 and Fig. 3, the joint regulating mechanism of this doll carriage that the present embodiment provides, comprises locating dowel pin 2, dead bolt 3, support 4 and sleeve pipe 5.Sleeve pipe 5 and support 4 are hinged by the hinge 6 of horizontal arrangement, concrete connection structure is: on sleeve pipe 5, be shaped with the first hinge hole 53, on support 4, be shaped with the second hinge hole 41, thereby described hinge 6 levels are through in the first hinge hole 53 and the second hinge hole 41, sleeve pipe 5 and support 4 is hinged.Locating dowel pin 2 consists of the circular pin rod 21 being connected as a single entity and circular pegs cap 22, and wherein the sectional dimension of circular pegs cap 22 is greater than the sectional dimension of circular pin rod 21.On sleeve pipe 5, radially to wearing, offer rivet hole 51 and pin-and-hole 52, demountable rivet 7 is wherein installed in rivet hole 51, pin-and-hole 52 vertical layouts and its aperture are slightly larger than the diameter of described pin cap 22.In a part of threading 5 of dead bolt 3, another part stretches out outside sleeve pipe 5, and is clipped in the stage clip 1 between dead bolt 3 and rivet 7 in the interior layout of sleeve pipe 5.And, on dead bolt 3, be shaped with the vertical through hole 31 of prolate shape and the horizontal through hole 32 of prolate shape, so-called " prolate shape ", is that the cross section of finger-hole is prolate shape, for the hinge 6 of hinged sleeve pipe 5 and support 4 through described horizontal through hole 32.Vertically place, the aperture, top of through hole 31 offers the deep gouge 33 corresponding with described pin cap 22.The pin rod 21 of locating dowel pin 2 from top to bottom penetrates in described pin-and-hole 52 and described vertical through hole 31, that one end that dead bolt 3 stretches out outside sleeve pipe 5 is shaped with the curved end (not marking in figure) that contacts cooperation with support 4, on support 4, be shaped with at least one can be stuck on dead bolt 3, with the locating groove 42 of the angle between fixed support 4 and sleeve pipe 5, on this routine medium-height trestle 4, be shaped with altogether the draw-in groove 42 described in two, on support 4, be also shaped with the pressure section 43 matching with pin rod 21.
In conjunction with shown in Fig. 3～Fig. 5, first the principle of work of the present embodiment is simply described below again: generally, a draw-in groove 42 on support 4 is stuck on dead bolt 3, and makes support 4 remain on the level attitude of Fig. 3.If support 4 cws need to be put down, need the conter clockwise tilting force first making progress to support 4, support 4 is subject to after tilting force upwards, under the curved end 34 of dead bolt 3 coordinates with contacting of support 4, support 4 is can extruding dead bolts 3 mobile to left side in Fig. 3, in this process, between dead bolt 3 and locating dowel pin 2, relatively moves, locating dowel pin 2 is shifted to the right part of vertical through holes 31 gradually, and stage clip 1 pressurized shortens.When locating dowel pin 2 moves to deep gouge 33 place of vertical through holes 31 rightmost sides, under self gravitation effect, the pin cap 22 on locating dowel pin 2 can sink in deep gouge 33, thereby dead bolt 3 is fixed in sleeve pipe 5 and can not sway, as Fig. 4.Afterwards, then reversing sense is to 4 one clws tilting forces of support, and because dead bolt 3 is to the interior segment distance that moved of sleeve pipe 5, while being turned to level angle under support 4 clockwise directions, dead bolt 3 just can not be stuck in aforementioned draw-in groove 42 again.Continue turnover bracket 4 under clockwise direction, the pressure section 43 on support 4 will upwards compress the bottom of locating dowel pin pin rod 21, and makes pin cap 22 leave deep gouge 33, and dead bolt 3 just moves right and contacts with support 4 under the elastic force effect of stage clip 1 like this.After support 4 is turned to the position shown in Fig. 5 downwards, dead bolt 3 just snaps in the another one draw-in groove 42 on support 4, from but support 4 can not continuing, turn over, locked the angle between support 4 and sleeve pipe 5.
In the present embodiment, the circular trough of described deep gouge 33, its slightly larger in diameter is in the diameter of described pin cap 22.
In the present embodiment, the axially bored line of described rivet hole 51 is horizontal distribution on described sleeve pipe 5.
Certainly, above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow people can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalent transformations of doing according to the Spirit Essence of the utility model main technical schemes or modification, within all should being encompassed in protection domain of the present utility model.
