The specific embodiment

Below with reference to accompanying drawings preferred implementation of the present utility model is elaborated.

Shown in Fig. 1,8, according to the virgin high pin dining chair folding articulation mechanism 3 of baby of the present utility model mainly is expansion and the folding that is used to control the support frame 10 of the virgin high pin dining chair 2 of baby, thereby it is presented launch stationary state 100 and folding state 200, and make the support of the virgin high pin dining chair 2 of baby when launching stationary state 100 more firm.

In the present embodiment, the virgin high pin dining chair 2 of baby comprises support frame 10 and seat 2.Seat 2 is installed on the support frame 10 movably, and it is used for being sitting in top dining for baby child.Support frame 10 comprises forward foot in a step support 11 and rear foot support 12, and both can folding draw close and launch and fix, thereby can support above-mentioned seat 2.

Cooperate Fig. 1 referring to shown in Fig. 2,3, in the present embodiment, folding articulation mechanism 3 comprises first pivot block 31 and second pivot block 32.First pivot block 31 and second pivot block 32 articulate, and both can comprise connecting

portion

33,34 respectively.In the present embodiment, connecting

portion

33,34 can be embodied as branch sleeve respectively, their sockets and be fixed on forward foot in a step support 11 and the upper end of rear foot support 12 respectively, and by first pivot block 31 and second pivot block, 32 drive forward foot in a step support 11 and rear foot support 12 pivot certain angles, thereby make forward foot in a step support 11 and rear foot support 12 can be folded to folding state parallel to each other 200.

First pivot block 31 and second pivot block 32 comprise radial first locating slot 35 and second locating slot 36 respectively, and folding articulation mechanism 3 can further include first detent mechanism 4 and second detent mechanism 5.

The first above-mentioned detent mechanism 4 is installed between first pivot block 31 and second pivot block 32, is used to control first pivot block 31 and second pivot block 32, makes both can fixed angle or freely rotate.It comprises release button 41, Positioning Gear 42 and elastic component 43.Positioning Gear 42 is installed between second locating slot 36 of first locating slot 35 of first pivot block 31 and second pivot block 32 movably; Elastic component 43 can be known any elastomer, for example compresses spring, and it is installed between second pivot block 32 and the Positioning Gear 42, is used to make Positioning Gear 42 to keep the while clip between first pivot block 31 and second pivot block 32.Discharge button 41 and be installed in movably on first pivot block 31, and extend a plurality of ejection ends 44 with a side butt of Positioning Gear 42.

Please continue referring to shown in Fig. 4,5.When forward foot in a step support 11 and rear foot support 12 are in stationary state, Positioning Gear 42 is subjected to the active force of elastic component 43 and keeps clip between second locating slot 36 of first locating slot 35 of first pivot block 31 and second pivot block 32, can't relatively rotate between the pivot block 31 and second pivot block 32 thereby making wins, thus forward foot in a step support 11 and rear foot support 12 are fixed in and launch stationary state 100 and folding state 200, also the angle of forward foot in a step support 11 and rear foot support 12 can be fixed in scope in addition less than 65 degree.

In the time will discharging forward foot in a step support 11 with rear foot support 12, the operator can press by discharging button 41, utilize its ejection end 44 to drive Positioning Gear 42, make it break away from first locating slot 35 of first pivot block 31 and enter second locating slot 36 of second pivot block 32 fully, can freely rotate thereby make between first pivot block 31 and second pivot block 32.Like this, the operator just can make front leg support frame 11 and rear foot support 12 go to folding state 200 from launching stationary state 100, or goes to expansion stationary state 100 by folding state 200.

When support frame 10 is in stationary state 100 or folding state 200, elastic component 43 can make Positioning Gear 42 automatically reset, make its again clip between first locating slot 35 and second locating slot 36, thereby first pivot block 31 and second pivot block 32 can't be relatively rotated.

Please continue referring to shown in Fig. 6,7, in the present embodiment, second detent mechanism 5 is installed between first pivot block 31 and second pivot block 32, is used to limit the scope of angle between forward foot in a step support 11 and the rear foot support 12.

In the present embodiment, second detent mechanism 5 comprises first limited block 51 and second limited block 52.First limited block 51 is installed in first pivot block 31, and it comprises first and ends to end face 53 and second only to end face 54.Second limited block 52 is installed in second pivot block 32, and it comprises the 3rd and ends to end face 55 and the 4th only to end face 56.In the present embodiment, first limited block 51 of second detent mechanism 5 and second limited block 52 can be respectively by first pivot block 31 and second pivot block, 32 one elongation mouldings, and can rotate with first pivot block 31 and second pivot block 32.

When current foot support 11 was flared to maximum angle with rear foot support 12, first only supports end face 53 and the 3rd only was in contact with one another to end face 55, and support frame 10 is in and launches stationary state 100.And current foot support 11 is when being folded to folding state 200 with rear foot support 12, and second ends and support end face 54 and the 4th and end to end face 56 mutual butts, excessively folds in order to stop first pivot block 31 and second pivot block 32.In these cases, Positioning Gear 42 just in time clip between first pivot block 31 and second pivot block 32, thus, first detent mechanism 4 and second detent mechanism 5 remain in support frame 10 and launch stationary state 100 or folding state 200, thereby reach safely, stablize firm effect.

More than disclosed only be preferred embodiment of the present utility model, can not limit rights protection scope of the present utility model with this certainly.Be appreciated that the equivalent variations of doing according to the utility model essence defined in the appended claims and scope, still belong to the scope that the utility model is contained.
