Abstract
The utility model discloses a puckering chair, the structure of the front leg of which is ameliorated comprising a backset, a pair of front legs, a pair of back front and a seat. The joint where the front leg and the frame of the seat are articulated connected is provided with reinforce, which is inosculated and fixed on the shape of the front leg. The reinforce partly increases the thickness of the parts of the front leg, the parts is the position where the front leg mainly bears strength; and the distance between the bottom of reinforce and the articulated spindle is longer than the distance between the articulated spindle and the top of the reinforce, so that the intensity of the front leg is reinforced during use and increase the life of the chair. The utility model has the advantages of simple conformation, reinforcing the strength bearing intensity of the front legs as well as reducing the cost increment.
Description
Technical field
The utility model relates to a kind of folding seat, relates in particular to the improvement of draw bail between foreleg and the seat frame.
Background technology
The convenience of carrying, depositing and transport because go out, fold furniture is subjected to the welcome of consumer and producer deeply, especially folding seat, it is tradition foldable chair not relatively, have take up room after light, the folding little, be convenient to advantages such as transportation is stocked, simple in structure, easy production, be widely used in various occasions such as family, meeting room, office.
For day by day ripe folding seat, its structure is also improved gradually.Yet the folding seat of prior art, the seat frame generally is directly to be connected by rivet with the foreleg of both sides, because folding seat is in use, foreleg need bear bigger pressure with riveted joint place of seat frame, after long-term the use, easy deformation, bending; Therefore in order to address this problem, businessman has taked the increase pipe thickness, or at pipe box of the position suit that is connected with the seat frame, with the intensity of increase foreleg, yet no matter adopts which kind of measure, and the cost of product is increased greatly.
The utility model content
The purpose of this utility model is to provide a kind of increase foreleg intensity, increases the service life, and cost increases the folding seat of few foreleg architecture advances.
Technical solution adopted in the utility model is: the folding seat of foreleg architecture advances, and the structure based on existing folding seat comprises:
A backrest;
A pair of foreleg is fixedly installed on the both sides of backrest respectively;
A pair of back leg is rotationally connected with a pair of foreleg;
A seat support, the both sides of its back end of frame are rotationally connected with two back legs respectively, and the both sides of approximate center seat frame are rotationally connected with two forelegs respectively, are provided with banking stop between foreleg and seat frame (or back leg and seat frame);
A pair of reinforced sheet is arranged on the inboard of foreleg, and the position that is connected with seat support seat frame, and it and foreleg shape match, and fixing with it.
Described foreleg is arc, U-shaped, I shape, L shaped or shape that other and foreleg match.
Described reinforced sheet is connected with the foreleg rivet.
Described reinforced sheet is threaded with foreleg.
Described reinforced sheet and foreleg welding.
The length of described reinforced sheet is greater than the width of chair frame, its bottom apart from the distance of foreleg and seat support drive-connecting shaft greater than the distance of drive-connecting shaft apart from its top.
The beneficial effects of the utility model are: adopt said structure, because foreleg, in the position that articulates with seat support seat frame, be provided with the foreleg shape and match, and fixing with it reinforced sheet, this reinforced sheet part has increased the thickness of foreleg, the position of strength is mainly born in this position foreleg just, and reinforced sheet bottom apart from the distance of drive-connecting shaft greater than the distance that articulates apart from the reinforced sheet top, so more foreleg intensity in use, the while has also increased the service life of folding seat.And adopt this structure, simple in structure, reach increase foreleg and be subjected to force intensity in, it is less that its cost increases.

Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model foreleg structural representation;
Fig. 3 is the A-A view of Fig. 2;
Fig. 4 is the utility model embodiment two foreleg structural representations;
Fig. 5 is the utility model embodiment three foreleg structural representations;
Fig. 6 is the utility model embodiment four foreleg structural representations;
Fig. 7 is the utility model embodiment four foreleg structural representations.
The specific embodiment
Embodiment one, as accompanying drawing 1, Fig. 2, shown in Figure 3, and the folding seat of the utility model foreleg architecture advances, the structure based on existing folding seat comprises:
A backrest 1;
A pair of foreleg 2 is fixedly set in respectively in the sleeve pipe of backrest 1 both sides, has been provided with the crossbeam 20 of reinforcement, firm effect between two forelegs;
A pair of back leg 3, the end is connected with foreleg 2 upsides by connector 30, and the sleeve pipe 301 and foreleg 2 suits of this connector 30 are fixed, and triangle body 302 articulates with the end of back leg 3;
A seat support 4, the both sides of its frame 41 rear ends articulate with two back legs 3 respectively, and the both sides of approximate center seat frame 41 articulate with two forelegs 2 respectively;
In the inboard of foreleg 2, as shown in Figure 3,, be provided with a pair of reinforced sheet 21 that matches with foreleg 2 shapes, this reinforced sheet 21 and foreleg 2 welding with the position that seat support seat frame 41 is connected; The length of reinforced sheet 21 is greater than the width of chair frame 41, its bottom apart from the distance of foreleg and seat support drive-connecting shaft greater than the distance of drive-connecting shaft apart from its top.
Adopt said structure, because foreleg 2, in the position that articulates with seat support seat frame 41, be provided with foreleg 2 shapes and match, and fixing with it reinforced sheet 21, these reinforced sheet 21 parts have increased the thickness of foreleg 2, the position of strength is mainly born in this position foreleg 2 just, and reinforced sheet 21 bottoms apart from the distance of drive-connecting shaft greater than the distance that articulates apart from reinforced sheet 21 tops, so more foreleg 2 intensity in use, the while has also increased the service life of folding seat.And adopt this structure, simple in structure, reach increase foreleg and be subjected to force intensity in, it is less that its cost increases.
Embodiment two, and as shown in Figure 4, be with embodiment one difference: foreleg is made by rectangular tube, and the reinforced sheet 21 of rivet connection is an I shape with it.
Embodiment three, as shown in Figure 5, are with embodiment one difference: foreleg 2 is made by rectangular tube, and the reinforced sheet 21 that is threaded with it is for L shaped.
Embodiment four, as shown in Figure 6, are with embodiment one difference: foreleg 2 is made by rectangular tube, and the reinforced sheet 21 that is threaded with it is U-shaped.
