Specific embodiment
A kind of new Pram folding structure including car body 11, folds swivel head 3 and button 8, is erected on the car body 11
It heads straight for being equipped with and folds cavity 4, laterally offers button cavity 6, fold cavity 4 and connected with button cavity 6, it is logical to fold swivel head 3
It crosses screw shaft 2 and screw hole 5 is mounted on and folds in cavity 4, folded swivel head 3 can be rotated along screw shaft 2, and screw hole 5 is opened in car body 11
It above and with folding cavity 4 connects, folding swivel head 3 includes the upright bar connecting portion 3-2 on top, the chuck 3-1 of rear side and bottom
Rotary head latch 3-3, rotary head latch 3-3 form a rotary head card slot 3-4, button at least provided with two groups between rotary head latch 3-3
8 are set in button cavity 6, and the bottom of car body 11 offers the positioning square hole 10 connected with button cavity 6, position in square hole 10
Set screw 9 is penetrated from bottom to top, button 8 includes the location hole 8-2 that button boss 8-1, the center vertical of outer end open up, preceding
The spring retention posts 8-3 and the button latch 8-4 of lower part that side is laterally set, button latch 8-4 ecto-entads be provided with it is outer, in,
Interior three pieces, three pieces button latch 8-4 are formed on inside and outside two buttons card slot 8-5, spring retention posts 8-3 and are arranged with resetting spring
7.There are one the positioning tools of square hole 10 along the length on 6 length direction of button cavity.Set screw 9 can be along the length of positioning square hole 10
Direction slidably reciprocates.
The outer end of the screw shaft 2 has been connected through a screw thread nut 1.
When installation, resetting spring 7 is put into the round hole of button cavity 6, button 8 is pushed into button cavity 6.Under
On and, set screw 9 is screwed into location hole 8-2, the positioning of complete paired keys 8 through positioning square hole 10, set screw 9.From upper and
Under, folding swivel head 3 is inserted into and is folded in cavity 4, the hole 3-5 folded on swivel head 3 is alignd with screw hole 5, screw shaft 2 passes through
Hole 3-5 and screw hole 5, resetting spring 7 is in compressive state at this time, and button 8 keeps the state of push-in button cavity 6.With screw shaft 2 with
The locking of nut 1 folds swivel head 3, completes to fold the installation of swivel head 3.At this point, button 8 pops up button cavity 6, resetting spring 7
It is released.Complete the installation of folding means.
When folding, under normality, upright bar connecting portion 3-2 is upright vertically, folds swivel head 3 and is locked in folding cavity 4
In, button 8 is positioned 9 latched position of screw, meanwhile, the mutual top pressures of rotary head latch 3-3 and button latch 8-4 coordinate, and mutually interlock
