Abstract

The invention relates to a folding supporting frame of a tent, which comprises four supporting rods and a middle seat, wherein the middle seat are pivoted with the top end of each supporting rod through a folding rod respectively; each supporting rod is connected with an assistant supporting rod; each assistant supporting rod forms a telescopic structure through the socket joint of an upper sleeve and a lower sleeve; the lower end of the lower sleeve is pivoted with the upper half of a corresponding supporting rod; a cross folding mechanism is arranged between two adjacent assistant supporting rods and is provided with an upper pair of pivoting points and a lower pair of pivoting points; the upper pair of the pivoting points are fixedly pivoted at the top ends of the upper sleeves of the two assistant supporting rods; and the lower pair of the pivoting points are pivoted on the lower sleeves of the two assistant supporting rods. Because the cross folding mechanism is connected on the assistant supporting rods and the assistant supporting rods are connected between the outer sides of the supporting rods and the extending ends of the folding rods at the top, the supporting rods tilts from the external underside towards the internal upside, and the entire folding supporting frame is cone-shaped and can better resist wind blowing or other transverse external force.

Description

A kind of folding supporting frame of tent

Technical field

The present invention relates to the structure of tent, specifically be meant a kind of folding supporting frame of tent.

Background technology

Existing foldable tent bracing frame; Generally include four support bars that vertically are provided with, these four support bars are positioned on foursquare four angles, are respectively equipped with a cross folding mechanism between two support bars on this each limit of square; This cross folding mechanism has two pairs of pivoting points up and down; Top a pair of pivoting point fixedly is articulated in the apical position with two support bars on one side, and following a pair of pivoting point can slide up and down to be articulated on these two support bars, forms folding structure thus.And the center top of four support bars is provided with a middle base, articulates through a folding rod respectively between the top of this middle base and four support bars, and when four support bar foldings were close together, each folding rod also can carry out corresponding folding.

In order to realize the folding of each cross folding mechanism, must guarantee that two support bars that this cross folding mechanism connected are parallel to each other, therefore four support bars are all perpendicular to the ground, are unfavorable for wind resistance or resist the active force in the external world, are easy to generate inclination.

Summary of the invention

The present invention provides a kind of folding supporting frame of tent, and its main purpose is that the structure that overcomes existing folding support frame is unfavorable for wind resistance or extraneous active force, the crank-sided shortcoming of opposing.

The present invention adopts following technical scheme: a kind of folding supporting frame of tent; Comprise at least three support bars and a middle base; Articulate through a folding rod respectively between this middle base and each supporting bar top; Be connected with an auxiliary support bar on its each support bar, each auxiliary support bar forms Collapsible structure by last sleeve pipe and setting of casing socket respectively, and its cased lower ending pivot is connected to the corresponding support bar first half; Be provided with a cross folding mechanism between adjacent two auxiliary support bars; This cross folding mechanism has two pairs of pivoting points up and down, and top a pair of pivoting point fixedly is articulated in the apical position of the last sleeve pipe of this two auxiliary support bar, and following a pair of pivoting point is articulated on the setting of casing of this two auxiliary support bar.

Aforementioned a kind of folding supporting frame of tent; Its each support bar becomes skewed setting, is tilted by top in the outer lower direction, and said each auxiliary support bar correspondence is positioned at each support bar outside; The said outer end that is connected in each folding rod between middle base and each supporting bar top stretches out; Form an extension, this each extension is provided with downward lug, and each lug is articulated in the upper end of the last sleeve pipe of corresponding auxiliary support bar.

Aforementioned a kind of folding supporting frame of tent, its cross folding mechanism comprises at least two pairs of crossbars horizontal and corresponding end articulates mutually.

Aforementioned a kind of folding supporting frame of tent; Its each folding rod that is connected between middle base and each supporting bar top comprises outer half section and interior half section respectively; Should connect through a connection piece between outer half section and interior half section; This connector comprises a diapire and this upwardly extending two side of diapire dual-side certainly, and outer half section, interior half section of said folding rod is articulated between this two side.

Aforementioned a kind of folding supporting frame of tent, its support bar are telescopic sleeve pipe.

Can know by above-mentioned description structure of the present invention; Compare with prior art, the present invention has following advantage: owing to cross folding mechanism is connected on the support bar, but be connected on the auxiliary support bar; And auxiliary support bar is connected between the folding rod elongated end at the support bar outside and top; Therefore support bar is tilted by top in the outer lower direction, and whole folding support frame is tapered, thereby can resist wind or other horizontal external force better.

The specific embodiment

The specific embodiment of the present invention is described with reference to the accompanying drawings.

A kind of folding supporting frame of tent; With reference to Fig. 1; Comprise four support bars 1 and a middle base 5; Articulate through a folding rod 3 respectively between this middle base 5 and each support bar 1 top, each support bar 1 residing position is foursquare four bights, and each folding rod 3 is that center one-tenth is radial with this middle base 5.Each support bar 1 comprises two joint sleeve pipes 11,12 of mutual socket, forms telescopic sleeve pipe.

Referring to figs. 1 through Fig. 4, be connected with an auxiliary support bar 4 on each support bar 1, each auxiliary support bar 4 forms Collapsible structure by last sleeve pipe 41 with setting of casing 42 sockets respectively, and the lower ending pivot of its setting of casing 42 is connected to corresponding support bar 1 first half.Be provided with a cross folding mechanism 2 between adjacent two auxiliary support bars 4; Cross folding mechanism 2 comprises three pairs of collapsible crossbars horizontal and corresponding end articulates mutually; This cross folding mechanism has two pairs of pivoting points up and down; Top a pair of pivoting point fixedly is articulated in the apical position of the last sleeve pipe 41 of this two auxiliary support bar 4, and following a pair of pivoting point is articulated on the setting of casing 42 of this two auxiliary support bar 4.

Referring to figs. 1 through Fig. 4,1 one-tenth skewed setting of its each support bar is tilted by top in the outer lower direction, and it is tapered that whole folding support frame struts the back.Each auxiliary support bar 4 correspondence is positioned at each support bar 1 outside; The said outer end that is connected in each folding rod 3 between middle base 5 and each support bar 1 top stretches out; Form an extension 33; This each extension 33 is provided with downward lug 34, and each lug 34 is articulated in the upper end of the last sleeve pipe 41 of corresponding auxiliary support bar 4.
