Detailed description of the invention
By above-mentioned accompanying drawing, this utility model embodiment will be elaborated again below.
As shown in Fig. 1～Fig. 8,1. upper joint, rotation dish, 12. slide openings, 13. rotation dish locating pieces, 2. hypozygal, 21. times rotation dishes, 22. locating dowels, 23. spring stacks, 3. armrest seat, 31. armrest seat locating pieces, 4. gear piece, 41. centre bores, 42. location hole, 43. joint tooths, 431. thrust surfaces, 432. sliding surfaces, 5. flexible member on 11..
Baby's umbrella carriage elasticity folding/unfolding joint mechanism, as shown in Figure 1 and Figure 2, serves mainly to facilitate rapid deployment or the Quick folding of Baby's umbrella carriage, and by applying this elastic joint mechanism on Baby's umbrella carriage, it is possible to facilitate the expansion of Baby's umbrella carriage to use and carry with.
Described elastic joint mechanism includes upper joint 1, hypozygal 2, armrest seat 3 and gear piece 4；Wherein, upper joint 1 is generally used for connecting handrail tube, and its lower end is provided with the upper rotation dish 11 of conjoined structure；Hypozygal 2 is generally used for connecting car foot tube, and its upper end is provided with the lower rotation dish 21 of conjoined structure, rotates up and down dish and be designed as the discoid of same diameter；The described circle centre position rotating up and down dish is attached also cross a center rivet, so that form concentric to be between the two rotationally connected relation.
The center of rotation of described lower rotation dish 21 is provided with the spring stack 23 of a cylindrical shape, elastic elements 5 it is set with on this spring stack, such as cylindrical spring, is additionally provided with two and makees symmetrically arranged locating dowel 22 centered by spring stack 23, and each locating dowel is both designed as flat rod structure.
It is provided with the gear piece 4 of disc-shaped between described upper rotation dish 11 and lower rotation dish 21, specifically gear piece closing is arranged between upper rotation dish 11 and lower rotation dish 21 and is interlocked mutually in formed installation cavity；Described gear piece 4 center is provided with the centre bore 41 passed for spring stack 23 activity, and pushing tow gear piece 4 is displaced outwardly by flexible member 5 under normal conditions along spring stack 23, the trend that i.e. moves away from lower rotation dish 21 direction；Be additionally provided with two on described gear piece 4 centered by centre bore 41, make hole, symmetrically arranged location 42, hole, each location to arrange position all corresponding with locating dowel 22 position on lower rotation dish 21, and use flat pore structure and with locating dowel 22 positioning assembling one by one；Therefore, gear piece 4 can relative under rotate dish 21 and move axially and but rotated by restriction.
Described upper rotation dish 11 is provided with two and makees symmetrically arranged slide opening 12 centered by center of rotation, then on adjacent, on the gear piece 4 of rotation dish 11 side, it is provided with two joint tooths 43 accordingly, each joint tooth is just fitted in the slide opening 12 of correspondence, each joint tooth 43 is both designed as right angled triangle block, the vertical of this right angled triangle block is set to thrust surface 431, and the inclined-plane of right angled triangle block is set to sliding surface 432.Therefore, when upper and lower joint relatively rotates expansion as shown in Fig. 3 ~ Fig. 5, joint tooth 43 can be slided by flexible member 5 pushing tow in slide opening 12, until thrust surface 431 contacts slide opening 12 inwall and obtains spacing, thus limits being rotated further when upper and lower joint is in deployed condition；When upper and lower joint relatively rotates as shown in Fig. 6 ~ Fig. 8 and folds, joint tooth 43 is just skidded off slide opening 12 by sliding surface 432 and pushing tow gear piece 4 compression elastic element 5 moves axially, thus releases joint tooth 43 and limit for the rotation rotating up and down between dish.
Described armrest seat 3 is rotatably installed in outside rotation dish 11, and be calculated as and rotate up and down discoid with diameter of dish, armrest seat locating piece 31 and the rotation dish locating piece 13 of rotary spacing it is respectively equipped with between this armrest seat 3 and upper rotation dish 11, specifically: launch when upper joint 1 is relative with hypozygal 2, this armrest seat locating piece 31 and rotation dish locating piece 13 contact with each other as shown in Figure 5, thus limit armrest seat 3 relative on rotate the rotation of dish 11 so that armrest seat 3 is maintained at horizontal level；Fold when upper joint 1 is relative with hypozygal 2, then armrest seat locating piece 31 and rotation dish locating piece 13 the most reversely depart from, thus do not interfere with and fold operation.
This utility model can be by designing joint tooth 43, hole 42, location on the gear piece 4 set up, and make joint tooth 43 coordinate the slide opening 12 of upper rotation dish 11, hole 42, location coordinates the locating dowel 22 of lower rotation dish 21, elastic pushing tow in conjunction with flexible member 5, can realize the expansion of whole articulation mechanism or fold operation, the design of this structure is simple, easy to operate, flexible, use reliable, therefore greatly facilitate the use of baby father and mother.
The above is only better embodiment of the present utility model, therefore all equivalence changes done according to structure, feature and the principle described in this utility model patent claim or modification, all should be included in this utility model patent claim.
