Abstract

The utility model provides a folding chair, which comprises front legs, rear legs, a backrest and a seat board. The front legs and the rear legs are respectively assembled at the two sides of the seat board through rotating hinges, the front legs can be glidingly sleeved with guide sleeves, which are hinged with the rear legs, the upper end parts of the front legs are fixed with the position-limiting piece of the guide sleeves, the guide sleeves are matched with the front legs, and the position-limiting piece is the backrest of the folding chair. The guide sleeves are composed of bushings and the lateral wings extended out by the bushings, the rear legs are provided with connecting pieces which are fixed with guide sleeves, and the connecting pieces are hinged with the lateral wings. The utility model adds sliding guide sleeves at the upper ends of the rear legs, thereby being able to move along the front legs. When the guide sleeves are positioned at the lower edge of the backrest, the chair is under the unfolding state, and the backrest at the moment plays the position-limiting function to the guide sleeves, without additionally arranging a position-limiting mechanism to limit the unfolding state of the chair, thereby the structure is simple and the usage is convenient. One side of the bushings which form the guide sleeves is respectively extended with the lateral wing, thus the chair can be more attachable to the front legs when being folded, the contact surface is increased, and the connective stability is improved.

Description

Folding seat

(1) technical field

The utility model relates to a kind of folding seat.

(2) background technology

Daily folding seat generally all adopts the top of back leg is inserted in the shrinkage pool of foreleg, directly connects with coupling spindle again, because when folding and opening, the friction mutually of the front and back leg of chair, thus impaired easily, and influence overall appearance; Also have a kind of outside of adopting back leg as for foreleg, both connect by axle, and the latter can rotate around the axis, and like this, chair needs to add stopping means, complex structure between seat board and front and back leg when opening.

(3) summary of the invention

The purpose of this utility model is to solve existing folding chair structure complexity, impaired shortcoming easily, provide a kind of simple in structure, be difficult for impaired folding seat.

For this reason, the utility model is taked following technical scheme:

A kind of folding seat, comprise foreleg, back leg, backrest and seat board, described foreleg, back leg are installed in the seat board both sides by rotary gemel respectively, slidably be socketed with guide pin bushing on the described foreleg, described guide pin bushing and back leg are hinged, described foreleg upper end is connected with the locating part of guide pin bushing, and described guide pin bushing cooperates with foreleg, and described locating part is the folding seat backrest.

Described guide pin bushing is made up of sleeve pipe, the extended flank of sleeve pipe, and described back leg is provided with guide pin bushing and is fixedly coupled part, and described connector and described flank are hinged.

The utility model has the advantages that: 1, add sliding guide sleeve, can move along foreleg in the back leg upper end.When guide pin bushing was positioned at the lower limb of backrest, chair was in open mode, and at this moment backrest just plays position-limiting action to guide pin bushing, and a mechanism that need not to limit in addition limits the open mode of chair, and is simple in structure, easy to use; 2, be extended with flank in sleeve pipe one side that constitutes guide pin bushing, when chair folds like this and foreleg more fit, increased contact-making surface, improved the connection steadiness.

(4) description of drawings

Fig. 1 is the utility model overall schematic;

Fig. 2 is a guide pin bushing part-structure schematic diagram.

(5) specific embodiment

With reference to accompanying drawing 1, a kind of folding seat, comprise foreleg 1, back leg 2, backrest 3 and seat board 4, described foreleg, back leg are installed in the seat board both sides by rotary gemel respectively, slidably be socketed with guide pin bushing 5 on the described foreleg, described guide pin bushing and back leg are hinged, and described foreleg upper end is connected with the locating part of guide pin bushing, described guide pin bushing cooperates with foreleg, and described locating part is the folding seat backrest.Described guide pin bushing is made up of sleeve pipe 6, the extended flank 7 of sleeve pipe, and described back leg is provided with guide pin bushing and is fixedly coupled part, and described connector and described flank are hinged.

Sliding guide sleeve along foreleg up and down slippage realize opening of chair or folding, when guide pin bushing slided into the backrest lower limb, folding seat was for opening locking state.

Claims (2)

1. folding seat, comprise foreleg, back leg, backrest and seat board, described foreleg, back leg are installed in the seat board both sides by rotary gemel respectively, it is characterized in that slidably being socketed with on the described foreleg guide pin bushing, described guide pin bushing and back leg are hinged, described foreleg upper end is connected with the locating part of guide pin bushing, and described guide pin bushing cooperates with foreleg, and described locating part is the folding seat backrest.
