Description

A kind of folded linkage and have the Collapsible dining chair for children of this mechanism

Technical field

The utility model relates to a kind of folded linkage, and the utility model also relates to a kind of Collapsible dining chair for children that has this folded linkage.

Background technology

Folding children's dining chair of the prior art, because the folding lock pin of control pallet separates setting with the folding lock pin of control backrest, in folding process, need respectively pallet and backrest to be carried out folding operation, this just needs the compounding practice of two hands just can finish the folding of dining chair, and can't carry out the one-hand fold action.

The utility model content

The Collapsible dining chair for children that the purpose of this utility model is to provide a kind of pallet, backrest folded linkage and has this link gear, make pallet fold mechanism and backrest fold mechanism have the interlock effect, like this, in folding process, by once singlehanded control operation, folding when can realize pallet and backrest.

For achieving the above object, the technical scheme that the utility model adopted is:

The folded linkage of a kind of pallet and backrest, first pallet folds lock pin, the folding lock pin of backrest that separable bottom with the folding lock pin of first pallet, upper end is replaced setting mutually, fold the hauling rope that is used to draw the folding lock pin movement of backrest that lock pin is connected and is provided with backrest, have first chute that matches with the shank of the folding lock pin of first pallet on it, second chute that matches with the shank of the folding lock pin of backrest and the guide member of fixedlying connected with rack body, the secondary locking piece that is rotationally connected with pallet and rack body respectively, the secondary locking piece is provided with the 3rd chute that matches with the shank of the folding lock pin of first pallet, slidably be provided with the folding lock pin of second pallet that an end has protuberance on the secondary locking piece, guide member is provided with a recess that is used to insert protuberance.

A kind of Collapsible dining chair for children, comprise rack body, be arranged on the pallet on the rack body, the rotating backrest that is arranged on the rack body and is positioned at the pallet rear, be used to control pallet and the folding folded linkage of backrest, folded linkage comprises that first pallet folds lock pin, the folding lock pin of backrest that separable bottom with the folding lock pin of first pallet, upper end is replaced setting mutually, fold the hauling rope that is used to draw the folding lock pin movement of backrest that lock pin is connected and is provided with backrest, have first chute that matches with the shank of the folding lock pin of first pallet on it, second chute that matches with the shank of the folding lock pin of backrest and the guide member of fixedlying connected with rack body, the secondary locking piece that is rotationally connected with pallet and rack body respectively, the secondary locking piece is provided with the 3rd chute that matches with the shank of the folding lock pin of first pallet, slidably be provided with the folding lock pin of second pallet that an end has protuberance on the secondary locking piece, guide member is provided with a recess that is used to insert protuberance.

Because the employing of technique scheme, the utility model compared with prior art has the following advantages:

In the folded linkage, folding lock pin of first pallet and backrest folded lock pin is separable replaces setting mutually, and form a cover pallet with the folding lock pin of second pallet, backrest folds linked system, in folding process, by the folding lock pin movement of hauling rope pulling backrest, the effect that reaches folding back or regulate the backrest inclination degree, simultaneously folding back and pallet if desired, then by increasing the displacement of the folding lock pin of hauling rope pulling backrest, make the folding lock pin of backrest replace the folding lock pin of first pallet, the folding lock pin of first pallet is replaced the folding lock pin of second pallet, make its protuberance take off recess on the guide member, the secondary locking piece can be rotated relative to rack body, realize the folding of pallet and backrest.Like this, by a control operation, folding when can realize pallet and backrest, the utility model also has advantage of simple structure simultaneously.
