Detailed description of the invention
In order to explain the technical solution of the utility model further, below by specific embodiment, the utility model is elaborated.
As shown in Figures 1 to 4, the utility model discloses a kind of folding chair frame structure, it comprises seat bracket 1, chair foot support 2 and is flexibly connected seat bracket 1 and the connection bracing frame 3 of chair foot support 2, seat bracket 1 can be combined with seat support cloth cover (not shown).
Described connection bracing frame 3 is one-body molded by plastic material, this connection bracing frame 3 comprises the connecting rod 32 of two groups of links 31 and lateral connection two link 31, each group of link 31 is fixed with each other by the leg sidewall of the two by two v-shaped tube 30 make-ups respectively, and the space internal fixtion that two v-shaped tubes that are placed in two link 31 make-ups are formed is stretched at the two ends of connecting rod 32 respectively, and the port of two legs of each v-shaped tube 30 is planted with each rod member of chair foot support 2 coordinate for seat bracket 1; Arrange elastic threads 4 between two rod members being plugged on same v-shaped tube 30, that is: this elastic threads 4 is through v-shaped tube 30 and connects two rod members.The connecting rod 32 of this connection bracing frame 3 is for having the hollow tube of at least openings at one side 321, and in connecting rod 32, activity is inserted with metal reinforced pipe 5.
Described seat bracket 1 comprises at least two front support rod 11 and at least two back poles 12, and wherein the length of back pole 12 is the length being greater than front support rod 11.
Described chair foot support 2 comprises at least four foot levers 21, and the bottom of each foot lever 21 is respectively equipped with a footmuff 6.
One end of described two front support rod 11, two back poles 12 and four foot levers 21 is inserted in each v-shaped tube 30 of connection bracing frame 3 respectively, the other end is arranged with a pipe close 7 respectively, pipe close 7 protrudes out a connecting piece 71 towards one end of rod member, brace 71 is provided with a perforate 72, and the setting of this brace 71 and perforate 72 is that to be convenient to wearing of elastic threads fixing.
Coordinate shown in Fig. 2, the leg port of each v-shaped tube of described connection bracing frame 3 30 is the jacks defining seat bracket 1 and each rod member of chair foot support 2, certainly, also the leg port of each v-shaped tube 30 can be formed necking down and be inserted in seat bracket 1 with each rod member of chair foot support 2.Wearing of elastic threads 4 is convenient in the setting of v-shaped tube 30.
During combination, connect in each v-shaped tube 30 of bracing frame 3 and wear elastic threads 4, the two ends of elastic threads 4 connect the rod member coordinated with respective v-shaped tube 30, then to wear to the perforate 72 of the pipe close 7 of each rod member fixing, so make seat bracket 1, chair foot support 2 and are connected bracing frame 3 and form Foldable chair frame.
When chair uses, only need seat bracket 1 and each rod member of chair foot support 2 be inserted in each port being connected each v-shaped tube of bracing frame 3 30; Otherwise the folding chair period of the day from 11 p.m. to 1 a.m, only seat bracket 1 need be extracted from each port being connected each v-shaped tube of bracing frame 3 30 with each rod member of chair foot support 2, owing to being limited to the effect of elastic threads 4, each parts are made to be unlikely to depart from, and can the compactest folding be realized, reach minimum folding volume, to facilitate collection and to carry.
Coordinate shown in Fig. 1, Fig. 2, the front support rod of seat bracket 1 11 and back pole 12 can be made up of more piece rod member again, and namely the end of each rod member can form the socket that necking down is beneficial to each other, so can shorten further rod member fold after length, order more reasonable fold.During use, pine oil, to the binding force of each rod member, shakes each rod member, under the resilient force of elastic threads 4, chair frame easily can be launched.
The above-mentioned front support rod 11 be made up of more piece rod member is or/and back pole 12 also realizes coordinating by connecting rod, and namely one end of each connecting rod is fixed in a rod member, and the other end and adjacent rod member are pivot bush unit relation.
Certainly, each foot lever 21 of chair foot support 2 also can adopt more piece rod member to form.
To sum up, after adopting such scheme, the utility model utilizes the v-shaped tube 30 of two mutual make-ups to form link 31, the connection bracing frame 3 that two links 31 form folding seat is connected again by a connecting rod 32, the port of each v-shaped tube 30 leg forms the jack of each rod member coordinating seat bracket 1 and chair foot support 2, formation one folding seat like this, and realize each rod member of folding seat by the elastic threads 4 be arranged in each v-shaped tube and be connected folding of bracing frame 3, realize structure simple, cost of manufacture is low and to fold volume compacter, more portable effect with collection.This connection bracing frame 3 adopts plastic material one-body molded, not only can ensure its stability, and processing is quick, plastic material cost is low and light, is easier to carry.In addition, the reinforced pipe 5 be located in connecting rod 32 increases the support strength connecting bracing frame 3 simultaneously.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field, to its suitable change done or modification, all should be considered as not departing from patent category of the present utility model.
