In the prior art, the paulin strut frame of large-scale account and small-sized tent-like seemingly generally include four masts and top supporting rod, are beneficial to folding (shown in Fig. 1 and Figure 1A) and between every adjacent two masts cross support bar group is set also.Different with small-sized tent is, in the strut frame of large-scale tent, the cross support bar group of at least two groups is set between every adjacent two masts, the strut frame is after propping up, four masts are perpendicular to the ground, and by two to three groups cross support bar group connection, cover tent cloth afterwards again and form complete tent between adjacent two masts.Be not difficult to find out that four weight that mast carried of large-scale tent strut frame are far longer than small-sized tent, when therefore bigger weight is pressed on the mast, often make the mast double swerve, and cause the strut frame built on the sand, especially when mast was perpendicular to the ground, this phenomenon was more obvious.

For solving above-mentioned deficiency, there is the dealer to design a kind of strut frame of mast introversion formula, as shown in Figure 2, the strut frame of this large-scale introversion formula tent is after propping up, and its four masts slope inwardly, after the weight of tent top presses down, four masts are not the vertical pressure that bears, but support outside the bottom, so its support steadiness is quite high, mast can double swerve.And be the purpose that reaches the mast introversion, the scheme that this strut frame adopts is shown in Fig. 2 A, the movable carriage 4 of this mast 1 ' go up to be provided with ' (shown in Figure 1A) of connection lug 41 ' more traditional long, and cross support bar group 3 ' a wherein inclined support bar 31 ' be articulated in this connection lug 41 ' outboard end, therefore, after whole strut frame is propped up, four masts 1 ' be subjected to movable carriage 4 ' ejection, make mast 1 ' the bottom outside support, thereby form the form of mast introversion.Yet there is certain defective also in this scheme: because described connection lug 41 ' more traditional length, after the folding of whole strut frame, its four masts 1 ' still be the form of introversion make folding back brace bridge form down the big little trapezoidal shape of, therefore volume is bigger after the folding, is unfavorable for collection.

The utility model content

The purpose of this utility model is to provide a kind of large-scale introversion formula tent strut frame, after it supports, and the mast introversion, and after the folding, mast is vertical.

For achieving the above object, technical solution of the present utility model is: a kind of large-scale introversion formula tent strut frame, comprise four masts and top supporting rod, and between every adjacent two masts, being provided with cross support bar group, this cross support bar group is made up of two cross-articulation inclined support bar together; Be movably equipped with in addition movable carriage on mast, a wherein inclined support bar of this movable carriage and adjacent cross support bar group is hinged; Wherein: the inclined support bar of the cross support bar group that is hinged with movable carriage, from the crosspoint to longer than all the other crosspoints of this cross support bar group to the length of end pin joint with the pin joint length of movable carriage.

Described large-scale introversion formula tent strut frame is provided with the cross support bar group of at least two groups between per two masts.

The inclined support bar of the cross support bar group that described and movable carriage are hinged, from the crosspoint to the pin joint length of movable carriage than all the other crosspoints of this cross support bar group the long 2-8 of length centimetre to the end pin joint.

After adopting such scheme, the utility model is after propping up, because the inclined support bar that links to each other with movable carriage is longer than remaining to the length in crosspoint by the end pin joint, therefore movable carriage will be subjected to this inclined support bar ejection and outwards, and then outwards support the bottom that drives mast, thereby make mast propping up the intilted form of back formation, support firm purpose to reach.

And the utility model is when folding, owing to driving four masts, the gathering effect of each cross support bar group inwardly draws in, at this moment, though the length of the inclined support bar that is hinged with movable carriage is long than the length of another inclined support bar, in the gathering process, this length will continue to drive movable carriage and move downward along mast, thereby make mast in vertical state, then be rectangular configuration after the folding of whole strut frame, so the volume after its folding is little, does not take up room.

The specific embodiment

As shown in Figure 3, the utility model comprises four masts 1 and top supporting rod 2 equally, and be provided with at least two groups between the every adjacent two masts 1 cross support bar group 3 of (among the figure be example with three groups) is beneficial to folding.Wherein:

Four masts 1 are the shape that can stretch up and down, further to reduce the folding volume of whole strut frame; And on four masts 1, be movably equipped with movable carriage 4, and movable carriage 4 is provided with and connects lug 41, and it is hinged with a wherein inclined support bar 31 of adjacent cross support bar group 3 that this connects lug 41; The top of four masts 1 also is provided with holder 5, and 5 of this holders are hinged with another inclined support bar 32 of cross support bar 2 with adjacent top supporting rod 2 respectively.

Cross support bar group 3 is made up of two cross-articulation

inclined support bar

31,32 together, and the two ends of two

inclined support bars

31,32 are hinged with holder 5 with the movable carriage 4 of adjacent another cross support bar group 3 or mast 1 respectively.
