Abstract
The utility model discloses an X pin connected member group's structure improvement. The utility model comprises member bars connected by the two fulcrums; the flank of one bar covers the thickening sheet which connects the fulcrum at the fulcrum joint place. Using the above structure, as two bars connecting position is provided with thickening sheet which tallies with the bar shape and connects the fulcrum, the thickening sheet increases the partial member thickness, and the spot is precisely the pivot link bar's main withstanding strength spot, moreover the thickening sheet covers the bars, while the utility model saves the cost, the model also increases the member joint and the stress intensity, thus also increases each kind of chair frame, the table composed of the utility model and the bed frame and so on each product support's stress intensity and the service life. Therefore the utility model has the simple structure, increases the member stress intensity, the service life, and the cost increases few and so on merits.
Description
Technical field
The X type that the utility model relates to a kind of folding table frame that is used to lie fallow, folding bedstead, folding seat frame articulates the structural improvement of rod member group.
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 leisure chaise longue, bed, table, tradition is not collapsible relatively for it, have take up room after light, the folding little, be convenient to that transportation is stocked, simple in structure, easy production, use comfortable, advantage such as loosen, be widely used in family and various leisure occasion.
For day by day ripe fold furniture, all kinds of supporting structures also improve gradually, as folding bedstead, folding seat frame and folding table frame, yet the support of all kinds of leisure products of prior art form for the ease of many being coupled to each other by X type connection pole group of folding, and X type connection pole is organized its two bar by pivoting together, when leisure chaise longue opens and uses, pivot end need bear bigger pressure, after long-term the use, and easy deformation, bending; Therefore in order to address this problem, businessman has taked the increase pipe thickness, or at pipe box of two pipe pivot points place's suits, is subjected to intensity of force to increase by two pipes, 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 being subjected to force intensity, increasing the service life of connecting rod that increase, and cost increases the structural improvement that few X type articulates the rod member group.
Technical solution adopted in the utility model is: the X type articulates the structural improvement of rod member group, articulate the structure of rod member group based on existing X type, it comprises two pivotally connected rod members, and at pivotally connected place, the outside of two bars all partly is coated with reinforced sheet and is connected jointly with pivot.
Described bar cross section is circular, or square.
Described reinforced sheet, its cross section are arc, U-shaped, I shape, L shaped or shape that other and rod member match.
The another technical scheme that the utility model is taked is: the X type articulates the structural improvement of rod member group, and it comprises two pivotally connected rod members, and at pivotally connected place, the outside of a bar is coated with reinforced sheet and is connected jointly with pivot.
Described bar cross section is circular, or square.
Described reinforced sheet, its cross section are arc, U-shaped, I shape, L shaped or shape that other and rod member match.
The beneficial effects of the utility model are: adopt said structure, because the position that two bar pivots connect, be provided with the rod member shape and match, jointly with pivotally connected reinforced sheet, this reinforced sheet has increased the thickness of local rod member, and this position just pivoted pole mainly bear the position of strength, and reinforced sheet partly coats rod member, like this in the cost-effective while, also increased the connection of rod member and be subjected to force intensity, thereby also increased being subjected to force intensity and service life by various product shelves such as its various chair framves of forming, table frame and bedsteads.So the utlity model has simple in structurely, increase rod member and be subjected to force intensity, service life, and cost increase advantages such as less.

The specific embodiment
Embodiment one, and as shown in Figure 1, the utility model X type articulates the structural improvement of rod member group, articulate the structure of rod member group based on existing X type, it comprises two pivotally connected rod members 11,11 ', and at pivotally connected place, the outside of two bars all partly is coated with reinforced sheet 10 and is connected jointly with pivot.
Embodiment two, and as accompanying drawing 2, shown in Figure 3, the structural improvement that the utility model X type is articulated the rod member group is used for the composition of chair shelf structure, and this chair frame comprises:
Chair seat frame 1 articulates four facades 101,102,103,104 that rod member group 10 constitutes chair seat frame 1 by four groups of X types, and each pole 11 end of adjacent facade are corresponding to articulate; The X type articulates the rod member group, comprises two pivotally connected circular rod members, and at pivotally connected place, the outside of two bars all partly is coated with arc reinforced sheet 12 and is connected jointly with pivot, and this reinforced sheet 12 matches with rod member 11 shapes; After two poles 11 of preceding facade 101 articulate, extend upward respectively and form left and right sides arm-rest frame 4;
Back rest 2 is fixedly installed on behind the chair seat frame vertical rod of facade both sides by two and forms.
The chair frame that adopts said structure to form, articulate rod member group 10 owing to form the X type of chair frame, the position that its two bar 11 articulates, be provided with rod member 11 shapes and match, jointly with pivotally connected reinforced sheet 12, this reinforced sheet 12 has increased the thickness of local rod member 11, and this position just pivoted pole mainly bear the position of strength, and reinforced sheet 12 partly coats rod member, like this in the cost-effective while, also increased the connection of rod member 11 and be subjected to force intensity, be subjected to force intensity and service life thereby also increased the chair frame of forming by it.
