Folding seat has Foldable and portable feature, and it is not only applicable to the use in open air and interim place, is also the Emergency use article of household indispensability.Mostly traditional folding seat is that supporting cloth cover by folding rack is formed, and the folding rack of formation coordinates multiple module composition by many poles, therefore folds volume comparatively large, preferably cannot embody the feature of light portable, easy-to-collection.

Utility model content

The purpose of this utility model is to provide that a kind of structure is simple, to fold volume compacter, the more portable folding chair frame with collection.

For achieving the above object, solution of the present utility model is:

A kind of folding chair frame, wherein: comprise a seat bracket, a chair foot support and be flexibly connected the connection bracing frame of seat bracket and chair foot support; Seat bracket is combined with seat support cloth cover; Described seat bracket comprises two front support rods and two back poles; This chair foot support comprises at least four foot levers; This connection bracing frame comprises four U-tube and two terminal pads, and terminal pad is respectively equipped with four perforation, be fixed together with terminal pad after two legs of each U-tube are each passed through the perforation of two terminal pads, and terminal pad is the leg place being fixed on each U-tube, two legs of each U-tube are planted with each rod member of chair foot support coordinate for seat brackets, arrange elastic threads between two rod members being plugged on same U-tube.

The cooperative end part of described seat bracket and each rod member of chair foot support forms necking down to be inserted in the leg port of each U-tube.

The leg port of described each U-tube forms necking down and is inserted in each rod member of seat bracket and chair foot support.

The back pole of described seat bracket is made up of more piece rod member.

Each rod member of described seat bracket and chair foot support adopts more piece rod member to form.

After adopting such scheme, the utility model utilizes two terminal pad location, directed four U-tube formation link, the port of the leg of each U-tube forms the jack of each rod member coordinating seat bracket and chair foot support, the collapsible chair frame of formation one like this, and realize each rod member of folding seat by the elastic threads be arranged in each U-tube and be connected folding of bracing frame, realize structure simple, cost of manufacture is low and to fold volume compacter, more portable effect with collection.

Detailed description of the invention

As shown in Figures 1 to 4, the utility model discloses a kind of folding chair frame, and 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 is combined with seat support cloth cover 5.

Described connection bracing frame 3 comprises four U-tube 31 and two terminal pads 32, and terminal pad 32 is respectively equipped with four perforation 321, after two legs 311 of each U-tube 31 are each passed through the perforation 321 of two terminal pads 32 and terminal pad 32 be fixed together, and terminal pad 32 is leg 311 places being fixed on each U-tube 31, the leg 311 of each U-tube 31 is adopt the fixed form of welding with terminal pad 32 herein, and make two legs 311 of each U-tube 31 radially distribute, and two legs 311 of each U-tube 31 are planted with each rod member of chair foot support 2 coordinate for seat brackets 1, described connection bracing frame 3 is the location realizing each U-tube 31 by two terminal pads 32, directed, arrange elastic threads 4 between two rod members being plugged on same U-tube 31, that is: this elastic threads 4 is through U-tube 31 and connects two rod members.

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.

Coordinate shown in Fig. 2, the leg port of each U-tube of described connection bracing frame 3 31 is the jacks defining seat bracket 1 and each rod member of chair foot support 2, certainly, also the leg port of each U-tube 31 can be formed necking down and be inserted in seat bracket 1 with each rod member of chair foot support 2.This embodiment is that seat bracket 1 and the cooperative end part of chair foot support 2 each rod member are formed necking down 10 to be inserted in the leg port of each U-tube 31, and so guarantee rod member is with to be connected bracing frame 3 overall appearance better.Wearing of elastic threads 4 is convenient in the setting of U-tube 31.

During combination, connect in each U-tube 31 of bracing frame 3 and wear elastic threads 4, the two ends of elastic threads 4 connect the rod member coordinated with respective U-tube 31, 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 U-tube of bracing frame 3 31; 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 U-tube of bracing frame 3 31 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. 3, 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, the utility model be utilize two terminal pads 32 to locate, directed four U-tube 31 form link 3, the port of the leg 311 of each U-tube 31 forms the jack of each rod member coordinating seat bracket 1 and chair foot support 2, the collapsible chair frame of formation one like this, and realize each rod member of folding seat by the elastic threads 4 be arranged in each U-tube 31 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.
