Abstract

The utility model relates to the tent technology field, in particular to a foldable tent frame. The technical scheme is that: a vertical pole of the rent is flexibly jacketed with a lower nest. And the upper end of the vertical pole is fixedly connected with an upper nest. One end of a large supporting pole is pivoted on the upper nest, and the other end of the large supporting pole is pivoted with a small supporting pole. The other end of the small supporting pole is pivoted on the top nest. One end of a branch pole is pivoted on the middle segment of the large supporting pole, and the other end of the branch pole is pivoted on the lower nest. The adjacent two lower nests and two lower nests are connected by a plurality of branch poles. The connecting poles are intertwined and hinged together to form a movable and extendable parallelogram bracket. In this way, the up-and-down movement of the lower nest can be realized by the continuous interaction of the large supporting pole, the small supporting pole, the branch pole and the branch pole. And the opening and closing of the rent bracket can be realized. The utility model is of convenient operation. The folded rent bracket is of relatively-small volume, and can be conveniently carried.

Description

Folding tent frame

Technical field:

The utility model relates to the tent technical field, refers in particular to a kind of folding tent frame.

Background technology:

The people that tent can be and go sightseeing, cooks a meal in the open air or be engaged in other outdoor study provide the environment of a provisional sun-shading rain-proof, have a wide range of applications in the modern life.The tent of Chu Shouing has two kinds of structures in the market: a kind of for assembly type, and when using, such tent earlier each tent frames is assembled, and cover tarpaulin on it again and fasten and can use.This class tent assembling and dismounting are all pretty troublesome, and skeleton is scattered, bad carrying.Another kind is collapsible, each skeleton of such tent is connected as a single entity, collapsible folding and unfolding, it is comparatively convenient to install and dismantle, but present most break camp causes the overall weight of break camp bigger because its ceiling bone adopts space truss structure, carry and be not very convenient, and because the structure of space truss is comparatively complicated, thereby the stability of the ceiling bone of this break camp is also bad, occurs the phenomenon that swings easily once meeting wind slightly.What the ceiling bone of some tent adopted is detachable crossbeam, and this structure has reduced mounting hardness, and its width or length are bigger but crossbeam is pulled down the back, need occupy suitable space when transportation, gives the very big problem of having brought of carrying again.

Summary of the invention:

The purpose of this utility model be to provide a kind of installation and the dismounting all very convenient, and fold the back volume less, carry folding tent frame more easily.

The utility model is achieved by the following technical solution: movable sleeve is connected to nest on the column of tent, and the upper end of column is fixed with nest, one end of big support bar is articulated in nest, the other end and ramuscule strut articulate, the other end of little support bar is articulated on the nest of top, an end that props up push rod is articulated in the stage casing of big support bar, the other end is articulated in down on the nest, nest and the connection of some poles is arranged respectively between the nest down on adjacent two, and respectively connect between pole and constitute the movable parallelogram bracket of stretching receipts after the cross-articulation mutually.

Described big support bar is provided with holding tank with the end that the ramuscule strut articulates and matches with the articulated section of little support bar; And the articulated section of little support bar can be integral production with little support bar or separate and make the back and engage and be one, little support bar with have a gap to cooperate after support bar folds greatly to fold with tarpaulin; Big support bar, little support bar and a push rod can be the entity body of rod or the hollow rod body of different shape.

Described column can be made as stretches two sections of receipts formulas or multistage cylinder; End face is an inclined-plane on the last nest, and last nest is provided with some pivot connected slots and articulates with big support bar and pole, so that make various difform tent framves.

After adopting such structure, only need to descend nest to slide up and down and to realize opening and folding of tent frame by big or small support bar, a push rod and the mutual sequence of pole, use easily, and it is less to fold the volume of back tent frame, carries very light.

The specific embodiment:

See accompanying drawing 1～5, the utility model includes some columns 1, top nest 2, ramuscule strut 3, big support bar 4, upward nest 5 reaches nest 6 down, and column 1 can be made as stretches two sections of receipts formulas or multistage cylinder, so that the volume of tent frame is further dwindled; Column 1 lower end connects a holder 7, and following nest 6 pivot bush units are on column 1, fixedlys connected with last nest 5 in the upper end of column 1, and the upper surface of last nest 5 is an inclined-plane, and like this, the tent that covers thereon is furnished with a gradient, makes things convenient for the rainwater landing.One end of big support bar 4 is articulated in nest 5, the other end is provided with holding tank 41 and matches with the articulated section 31 of ramuscule strut 3, and articulate with ramuscule strut 3, the other end of ramuscule strut 3 is articulated on the top nest 2, engage after ramuscule strut 3 can be integral production with its articulated section 31 or separates making and be one, an end that props up push rod 8 is articulated in the stage casing of big support bar 4, the other end is articulated in down on the nest 6, nest 5 reaches on adjacent two has some poles 9 to connect down respectively between the nest 6, and constitutes the movable parallelogram bracket of stretching receipts after respectively connecting 9 mutual cross-articulation of pole.

When using the utility model, to descend nest 6 upwards to pass, at this moment the push rod 8 and the pole 9 that are connected in down on the nest 6 are all launched outward, an end that props up push rod 8 acts on big support bar 4 upwards struts its pivoting point around last nest 5, act on ramuscule strut 3 when moving on the other end of big support bar 4, the other end of ramuscule strut 3 is propped up top nest 2, expand on the same axis until ramuscule strut 3 and big support bar 4, catching groove in nest 6 and the button hook 11 on the column 1 are fastened and connected at present for these, thereby fasten down nest 6, prevent down that nest 6 glides, and then support big support bar 4, the most whole tent frame struts.When launching outward for pole 9, the some poles that are hinged 9 interact, and movable parallelogram changes and struts adjacent upright posts 1, makes the tent frame expand into a square.By the holder 7 on column 1 lower end, each column 1 is fixed in ground or other appropriate location, i.e. tent installation at last.After using, earlier fixing nail on the holder 7 is dismantled during dismounting, pressing down button 61 on the nest 6 again makes button hook 11 on the column 1 withdraw from down the catching groove of nest 6, pulling nest 6 is down glided along column 1, at this moment being articulated in down the big support bar 4 of push rod 8 pullings on the nest 6 is directed downwards toward columns 1 and folds, when also acting on ramuscule strut 3 it is moved down, the outer end of big support bar 4 folds to big support bar 4 doublings, ramuscule strut 3 other ends move down along band top nest 2, to four columns 1 with its bag cage in inside, ramuscule strut 3 has a gap can hold tarpaulin after folding with big support bar 4, in order to avoid the tent frame damages tarpaulin and scratch by pressure can not fold fully or fold the time; And pole 9 is when down nest 6 moves down, and the movable parallelogram of its formation changes, and draws together existing function of stretching receipts in.Tent can folding be a branch of, very convenient to carry like this.
