Detailed description of the invention

Clearer for the purpose making this utility model implement, technical scheme and advantage, implement below in conjunction with the present invention Accompanying drawing in example, is further described in more detail the technical scheme in the embodiment of the present invention.In the accompanying drawings, the most identical Or similar label represents same or similar element or has the element of same or like function.Described embodiment is this Invent a part of embodiment rather than whole embodiments.The embodiment described below with reference to accompanying drawing is exemplary, purport It is being used for explaining the present invention, and is being not considered as limiting the invention.Based on the embodiment in the present invention, the common skill in this area The every other embodiment that art personnel are obtained under not making creative work premise, broadly falls into the model of present invention protection Enclose.

In the description of the technical program, it is to be understood that term " " center ", " longitudinally ", " laterally ", "front", "rear", The orientation of the instruction such as "left", "right", " vertically ", " level ", " top ", " end " " interior ", " outward " or position relationship are for based on accompanying drawing institute The orientation shown or position relationship, be for only for ease of and describe the present invention and simplify description rather than instruction or the dress of hint indication Put or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that protect the present invention The restriction of scope, the utility model is described in further detail below in conjunction with the accompanying drawings:

Embodiment: refer to shown in Fig. 1 to Fig. 3, a kind of folding seat, including the seat support 1 being hinged, backrest 2, and it is used for The front support leg 3 of support, rear leg 4, also include that symmetrically arranged two handrails 5, any one handrail tail 5 end described are hinged on backrest 2 lateral surface and its be provided with can front support leg hinge hole 51 hinged with front support leg 3, rear leg 4 respectively and rear leg hinge hole 52, Described front support leg hinge hole 51, rear leg hinge hole 52 are separately positioned on inside and outside handrail 5, for hinged front support leg 3 and Rear leg 4.Specifically, seat support 1 described in the present embodiment and backrest 2 include seat pipe and penstock, wherein seat pipe and penstock respectively On be arranged with support cloth, the rotatable riveting of described seat pipe have connection sheet 6, also rotatable with the penstock riveting of this connection sheet 6, from And realize between seat support 1 and backrest 2 hinged, aforesaid front support leg 3 termination is hinged on and is positioned at the front support leg in front inside handrail 5 On hinge hole 51 and also optional with seat support 1 riveting at its corresponding seat support 1, and rear leg 4 be hinged on be positioned at outside handrail 5 close On the rear leg hinge hole 52 of tail end；Each handrail 5 includes that front portion, middle part and rear portion, described handrail 5 rear portion are articulated with backrest 2 side In the middle part of wall, it is anterior that rear leg 4 top is articulated with handrail 5.

As shown in Figure 1 to Figure 3, for the space reducing front support leg 3 further, rear leg 4 folds and occupies, described respectively hold up Hands 5 arranges the forward foot in a step groove 53 suitable with front support leg hinge hole 51 and rear leg hinge hole 52 and rear foot groove 54, for respectively Front support leg 3 after accommodating and folding and rear leg 4.Specifically, shown in Fig. 9, described forward foot in a step groove 53 inside handrail 5, And rear foot groove 54 is outside handrail 5, and forward foot in a step groove 53 and rear foot groove 54 be arranged in parallel, before front support leg 3 and rear leg 4 difference Leg hinge hole 51, rear leg hinge hole 52 rotate towards backrest side counterclockwise for axle, and then obtain front support leg 3 and be positioned at rear leg Foldable structure in 4, thus effectively solve existing because foot tube stacking and cause the technology such as area occupied is big, cost of transportation is high to ask Topic.

As shown in Fig. 1, Fig. 4, Fig. 5, Fig. 6, Fig. 7 and Fig. 8, aforementioned rear leg 4 is provided with for realizing stable support Rotate fixed mechanism 7.Described rotation fixed mechanism 7 includes rotation seat 71 and location fastener 72, and described location fastener 72 is positioned at and turns Above dynamic seat 71, wherein said rotation seat 71 one end is rotatable to be riveted on rear leg 4, its other end and the rotatable riveting of backrest 2 Connecing, described location fastener 72 is set on rear leg 4 and can coordinate fixing with rotation seat 71, in order to realize location fastener 72 Along rear leg 4 axial limiting.Specifically: described location fastener 72 coordinates clamping one end to be block end with rotation seat 71, this card Fixed end is provided with the positioning convex column 721 suitable with rotation seat recess, also has and can coordinate to solid with rotation seat corresponding surface Confined planes 722.

As shown in Fig. 1, Fig. 4, Fig. 5, Fig. 6, Fig. 7 and Fig. 8, fastener 72 side, aforementioned location is further opened with U-shaped slot segmentation 723, form flexure strip 724, this flexure strip 724 is provided with positioning boss 725, described positioning boss 725 inside the fastener of location Can coordinate, in order to realize this location fastener 72 at any one place of rear leg 4 with leg 4 outer surface after installing location fastener 72 Location.Specifically: rear foot tube 4 is through location fastener 72 thus extrudes positioning boss 725 and makes flexure strip 724 elastic deformation, institute State positioning boss 725 and produce frictional force under the effect of elastic-restoring force and between its rear leg 4 outer surface with flexure strip 724, So that the location fastener 72 any point on rear foot tube 4 can overcome self gravitation to remain static, thus solve Prior art exists the technical problems such as bearing capacity the best operation simultaneously inconvenience.

Preferred technical scheme is: as shown in Fig. 1, Fig. 4, Fig. 5, Fig. 6, Fig. 7 and Fig. 8, in order to limit location fastener 72 Displacement on rear leg 4, described location fastener 72 is offered a displacement position-limiting hole 726, and this displacement position-limiting hole 726 can be with spacing Post 73 coordinates, in order to limit the displacement along rear leg 4 of the location fastener 72；Specifically, described displacement position-limiting hole 726 is along rear The bar hole that foot 4 is axially arranged, limited post 73 is then that rear leg 4 stretches out that to be formed can be that hole coordinates location with displacement county Cylinder, described displacement position-limiting hole 726 can coordinate with limited post 73, in order to limit location fastener along the displacement of rear leg.

As shown in Figures 1 to 9, this structure specifically folds as follows:

Seat support 1 and backrest 2 first to folding so that front support leg 3 and rear leg 4 respectively with front support leg hinge hole 51, after Leg hinge hole 52 rotates towards backrest side counterclockwise for axle so that front support leg 3 is placed in the forward foot in a step groove 53 of handrail 5, then props up Foot 4 is placed in the rear foot groove 54 of handrail, and rotation seat 71 separates with location fastener 72, thus realizes the folding (see Fig. 9) of folding seat； Otherwise, it is achieved the expansion of folding seat.

Described above, only utilize the embodiment of this origination techniques content, any those skilled in the art to use this wound Make modification, the change done, all belong to the scope of the claims that this creation is advocated, and be not limited to those disclosed embodiments.
