The first cradle head 5, the second cradle head 6, third cradle head 7 are carried out to by above-mentioned unlocking structure below The process description of linkage of unlocking is as follows: pulling knob 81, the first hauling rope drives the rotation of the second sliding block 72 and third is pushed to lock Part 71 is slided towards backrest joint element for bar 61, until third sticking department 711 is detached from the locked groove on service plate connector 73, service plate connector Locking effect failure between 73 and backrest joint element for bar 61, third cradle head 7 are unlocked, and service plate connector 73 is with respect to backrest Bar connection rotation；First hauling rope seat 83 with service plate connector 73 rotate, the second hauling rope 84 drive the first sliding block 62 rotation and The second locking piece 63 is pushed to slide towards upper pright stanchion connector 64, until the second sticking department 631 is detached from the second locked groove 632, back support bar Locking effect failure between connector 61 and upper pright stanchion connector 64, the second cradle head 6 are unlocked, backrest joint element for bar 61 It is rotated relative to upper pright stanchion connector 64；Second hauling rope seat 85 is rotated with backrest joint element for bar 61, and third hauling rope drives first Locking piece 54 moves up, to be detached from the first locked groove 501, the first cradle head 5 is unlocked, and fore-stock connector 52, after-poppet connect Fitting 53 is rotated relative to lower upright bar connector 51.

It should be noted above-mentioned first pivot 91, the second pivot 92, third pivot 93, the 4th pivot 94, Wushu The axial line of axis 95 and the 6th pivot 96 is mutually parallel and preferably extends in left-right direction, as shown in Figure 1.Two side stands The axial line of first pivot 91 coincides, and the axial line of the second pivot 92 of two side stands coincides, and the of two side stands The axial line of three pivots 93 coincides, and the axial line of the 4th pivot 94 of two side stands coincides, and the 5th of two side stands the The axial line of pivot 95 coincides, and the axial line of the 6th pivot 96 of two side stands coincides, so that the children of folded state Dining chair volume further decreases.In above-mentioned four-bar mechanism, the upper end of connecting rod 14 is especially by 92 He of the second pivot The backrest joint element for bar 61 of second cradle head 6 rotates connection, that is to say, that connecting rod 14 and back support bar can pass through back support bar Connector 61 is rotatablely connected indirectly, can also be directly rotatablely connected.5th pivot 95 is located at the front lower place of the second pivot 92, and first Pivot 91 is located at the front lower place of third pivot 93.

Lateral frame includes multiple cross bar components that can be laterally folded or flexible, such as first crossbar component 21, second crossbar group Part 22 and third cross bar component 23.Specific in the present embodiment, each cross bar component respectively includes outer bar 2a and can be along right and left To the interior bar 2b for being slidably connected to outer bar 2a, one of them in outer bar 2a, interior bar 2b connects and another with left side brackets It is connected with right side bracket.As shown in Fig. 2,5, outer bar 2a can be slidably sheathed on interior bar 2b in left-right direction, so as to along a left side Right direction transverse direction folding.Preferably, cross bar component specifically includes the between 11 upper end of back support bar for being connected to the left and right sides One cross bar component 21, be connected to the left and right sides 15 lower part of fore-stock between second crossbar component 22 and be connected to left and right two Third cross bar component 23 between the after-poppet 16 of side.Wherein, in first crossbar component 21, the back support bar 11 in interior bar 2b and left side The back support bar 11 on connection, outer bar 2a and right side connects；In second crossbar component 22, the fore-stock 15 in outer bar 2a and left side is connected, Interior bar 2b and the fore-stock on right side 15 connect；In third cross bar component 23, the after-poppet 16 in interior bar 2b and left side is connected, outer bar 2a It is connected with the after-poppet 16 on right side.It should be noted that in one preferred embodiment, the outer bar 2a's of each cross bar component Length is identical, and the length of interior bar 2b is identical, after laterally folded, the spacing of two sides back support bar 11, the spacing of fore-stock 15 and rear branch The spacing of frame 16 is identical, and folded children dinning chair is more regular, volume further decreases.

Service plate 31 and the service plate connector 73 of third cradle head 7 are detachably connected, thus service plate 31 can connect with service plate Fitting 73 be detached from so that children dinning chair be able to carry out it is laterally folded.

The folding principle of the children dinning chair of the present embodiment is as follows:

The unfolded state shown in Fig. 1-4, the first cradle head 5, the second cradle head 6, third cradle head 7 are locked Fixed, rod assembly 12, back support bar 11, connecting rod 14 and seat post 13 are opposite to be unfolded, fore-stock 15 and the also opposite exhibition of after-poppet 16 It opens, service plate 31 is connected on service plate connector 7332 and is generally in level；

When starting to fold, knob 81 is pulled to make third cradle head 7, the second cradle head 6, the unlock of the first cradle head 5, Service plate 31 is turned over upwards, until drawing close with back support bar 11, as shown in Figure 5,6；

Service plate 31 and back support bar 11 downwardly turn over backward, with back support bar 11 rotate, connecting rod 14 drive seat post 13 with Rotation so that 13 front end of seat post upwards and rear end is downward, until seat post 13 front end, connecting rod 14 and rod assembly 12 Upper end, back support bar 11 lower end draw close and the rear end of seat post 13, connecting rod 14 and rod assembly 12 lower end, lean on The upper end of back bar 11 is drawn close, as shown in Figure 7,8；

Fore-stock 15, after-poppet 16 overturn forward and up to the upper end of its lower end and rod assembly 12 and draw close, and two The side stand of side completes the folding on up and down direction and front-rear direction, as shown in figs. 9-11；

Then, service plate 31 is removed from service plate connector 7332, disengages it from side stand；Left side brackets are pushed to the right And/or right side bracket is pushed to the left, make the interior bar of first crossbar component 21, second crossbar component 22, third cross bar component 23 2b is contained in outer bar 2a, so that two side stands are mutually drawn close, completes the folding on left and right directions, children dinning chair is in as schemed Folded state shown in 12-14.

Children dinning chair according to the present utility model, folded compact；Can linkage of unlocking, folding convenient；Dining chair It is just adjustable, it is easy to use.

Embodiment 2

Substantially with embodiment 1, the difference with embodiment 1 is only that the present embodiment: service plate 31 includes the meal with two sides respectively The service plate left part 311 and service plate right part 312 that disk connector 73 is fixedly connected, service plate left part 311 can slidably connect in left-right direction It is connected to service plate right part 312, service plate left part 311 and service plate right part 312 are mutually drawn close, thus when laterally folded, nothing Service plate 31, which need to be removed, can be carried out lateral folding.In specific such as Figure 15-18, service plate left part 311 can in left-right direction slidably It is inserted in service plate right part 312, when children dinning chair is in folded state, service plate left part 311 is housed in service plate right part 312.

The above embodiments are only for explaining the technical ideas and features of the present invention, is preferred embodiment, purpose It is that person skilled in the art can understand the content of the utility model and implement accordingly, can not be limited with this practical Novel protection scope.
