Abstract

The utility model discloses a folding chair. The folding chair comprises two front supporting legs and two rear supporting legs, wherein an upper connecting rod is arranged between the two front supporting legs; an upper connecting rod and a lower connecting rod which are parallel with each other are arranged between the two rear supporting legs; a seat plate and a backing plate are connected with the two front supporting legs and the two rear supporting legs; the middle part of each front supporting leg is bended twice to form a supporting part; an arc-shaped groove and a mounting hole are formed on the rear side part of a lower bending section of the supporting part; a supporting base is arranged on the top of each rear supporting leg; a small supporting plate which extends slantways and upwards and can be inserted into the arc-shaped groove is arranged on the supporting base; the end part of the small supporting plate is hinged with the mounting hole through a connecting pin; and folding hardware components by which the front supporting legs and the rear supporting legs can be folded are arranged between the upper connecting rod of the front supporting legs and the upper connecting rod of the rear supporting legs at intervals. The front supporting legs of the chair are designed to be a two-section bending structure and the upper semi-section of each front supporting leg is inclined backward after being bended, so that a back can be farther away from the seat plate; and the front supporting legs, the rear supporting legs and the seat plate are connected to be a whole through the folding hardware components, so the chair is more stable and durable after being unfolded.

Description

A kind of folding seat

Technical field

The utility model relates to furniture, is specifically related to a kind of folding seat.

Background technology

In the prior art, folding seat all has application in household and work, the structure of existing folding seat all is by front support leg usually, rear leg, seat and backrest are formed, its front support leg adopts straight-bar shape structure, the backrest that connects in the top can be very forward, when the people is sitting on the chair, because backrest is forward, people's upper body can not obtain bigger gradient, this folding seat is sat up so uncomfortable, if backrest is installed backward, then must strengthen the gradient of front support leg, do like this, can influence the moulding of chair and attractive in appearance, in addition, the folding component of existing folding seat is simple in structure, before normally the mode of employing exposure is contained in, the junction of rear leg, also to offer chute in the both sides of seat, there are following defective in this foldable structure and mode: make that the profile of chair is not attractive in appearance, folding hardware component is arranged on the both sides of chair, chair stable bad.

The utility model content

The purpose of this utility model is, at the above-mentioned defective of prior art, provides a kind of good looking appearance, the comfortable folding seat of seating.

The technical scheme that the utility model provides is as follows: a kind of folding seat is provided, comprise two front support legs, article two, rear leg, article two, be provided with upper connecting rod between the front support leg, article two, be provided with between the rear leg two parallel on, lower link, between the leg of described front and back, be connected with seat board and backup plate, twice crooked formation, one support portion, the middle part of described front support leg, rear lateral portion at the following bending section of this support portion has a deep-slotted chip breaker and installing hole, a supporting seat is equipped with at the top of described two rear legs, have one to tilt to protrude upward on the supporting seat, and can insert the little gripper shoe in the described deep-slotted chip breaker, the end of little gripper shoe is hinged by connecting pin and described installing hole, at the folding hardware component that is interval with between the connecting rod on connecting rod on the described front support leg and the described rear leg for described front support leg and rear leg folding.

In above-mentioned folding seat, described folding hardware component is connected to form by two folding bearings, one of them folding bearing is provided with a Connection Block and is connected with the last connecting rod of described rear leg, be hinged with second Connection Block on this Connection Block, second Connection Block is connected with described seat board bottom, the outer end of second Connection Block has the hole, another folding bearing is provided with a Connection Block that is connected with connecting rod on the described front support leg, be hinged with a microscler brace on the Connection Block, the other end of brace is connected by the hole of connecting pin with the described second Connection Block outer end.

Advantage of the present utility model is as follows: be designed to two sections bending-type structures by the front support leg with chair, the upper semisection of front support leg is that the bending back is sweptback, so backrest can be farther from the position of seat, when sitting down, people's the upper part of the body can be more comfortable, folding hardware component is arranged on below seat and with forward and backward leg on connecting rod be connected, folding hardware component does not expose, simultaneously, folding hardware component is connected as a single entity forward and backward leg and seat, can be more firm and durable after chair is opened.
