Abstract
The utility model discloses the structural improvement of a tent brace rod support, which comprises four pillars and a top brace rod; side brace rods are arranged among each two contiguous pillars; a sliding seat is glidingly sheathed on the pillar, and the side brace rods are hinged on the sliding seat; in addition, a middle brace rod is provided for supporting the top brace rod; the middle brace rod comprises two independent support rods; one ends of the two support rods are hinged on the top brace rod, and the other end are respectively hinged on the side brace rods arranged at both sides of the top brace rod. When the brace rod support is unfolded, a tripodism is formed by two brace rods and the top brace rod; thus, the entirety support is firm.
Description
Technical field
The utility model relates to a kind of tent strut shelf structure improvement.
Background technology
In the prior art, the strut shelf structure of foldable tent, generally include four masts 1 ' and top supporting rod 2 ', and between every adjacent two masts, also be provided with side support bar 3 ', this side support bar 3 ' in order to support the cross bar between adjacent mast, perhaps as shown in Figure 1, support adjacent mast 1 ' cross bar change cross support bar group into, described side support bar 3 ' for be arranged at two adjacent masts 1 ' of one group of cross support bar group side downside, in addition, also have support bar 4 in ' with support, top support bar 2 ', above-mentioned side support bar 3 ' with middle support bar 4 ' all a be articulated in sliding seat 5 ' on, four masts 1 of this sliding seat 5 ' then be placed in ' on.
There is following shortcoming in above-mentioned tent strut frame:
1, because middle support bar 4 ' top supporting rod 2 ' and mast 1 ' between in the formed plane, therefore when expansion and folding, middle support bar 4 ' can only in described plane, produce stay bolt power, and to top supporting rod 2 ' side direction can't produce active force, thereby after expansion, the integrated support of tent strut frame is unsatisfactory, especially it supports unstable more for large-scale tent, because, large-scale tent takes advantage of the weight of carrying heavier, downforce in the single plane of top supporting rod 2 ' centering support bar 4 ' produced, support bar 4 in the often making ' phenomenon of double swerve occurs causes support firm inadequately.
2, on the operating principle during from folding, since this top supporting rod 2 ' in the centre, during folding, user's strength all act on side support bar 3 ' on, so its folding process be side support bar 3 ' drive sliding seat 5 ', support bar 4 in the pulling of sliding seat 5 ' again ', middle support bar 4 ' drive again top supporting rod 2 ', finish the folding action at last, be not difficult to find out, in the folding process, sliding seat 5 ' stressed bigger, sliding seat 5 ' just must adopt material to make like this with higher-strength, cost is higher, in addition, finally act on during folding top supporting rod 2 ' on folding power less, thereby be unfavorable for folding.
The utility model content
The purpose of this utility model is to provide a kind of tent strut shelf structure improvement, and it supports firm and is easier to folding.
For achieving the above object, technical solution of the present utility model is: a kind of tent strut shelf structure improvement, comprise four masts and top supporting rod, between every adjacent two masts, be provided with the side support bar, the mast upper sliding sleeve has a sliding seat, this side support bar is articulated on this sliding seat, in addition, also has in one support bar with the support, top support bar; Should comprise two independently struts by middle support bar, an end of this two strut is articulated on the top supporting rod, and the other end then is articulated in respectively on the side support bar of top supporting rod both sides.
This side support bar is provided with a connecting seat, and the described strut other end is articulated on this Connection Block.
The described strut other end is articulated on the sliding seat of side support bar end.
After adopting such scheme, because support bar is set to independently two struts in of the present utility model, and the other end of this two strut is articulated on the side support bar of both sides correspondence, tent strut frame upon deployment, described two struts are positioned at different planes with top supporting rod, and the formation gusseted, so integrated support is not quite firmly rocked.
In addition, the utility model is when folding, and the side support bar is the inside folding of support bar in the direct pull, and need not pass through sliding seat, so the power that sliding seat bore is much smaller relatively, and the support bar pulling force is also relatively large in acting on, thereby makes folding easier.
Description of drawings
Fig. 1 is an overall structure schematic diagram of commonly using tent strut frame;
Fig. 2 is an overall structure schematic diagram of the present utility model;
Fig. 3 is the partial enlarged drawing of Fig. 2;
Fig. 4 is the partial structurtes schematic diagram of another embodiment of the utility model.
The specific embodiment
As Fig. 2, the utility model shown in 3 is identical with located by prior art, comprise four masts 1 and top supporting rod 2, and between every adjacent two masts, also be provided with side support bar 3, this side support bar 3 is in order to support the cross bar between adjacent mast, perhaps as shown in the figure, the cross bar that supports 1 of adjacent mast changes cross support bar group into, described side support bar 3 is one of one group of cross support bar group side downside being arranged at 1 of two adjacent mast, on mast 1, go back sliding sleeve one sliding seat 5 is arranged, this side support bar 3 is articulated on this sliding seat 5, in addition, also has in one support bar 4 with support, top support bar 2.
Different is the utility model: support bar 4 comprises two independently struts 41,42 in described, and an end of this strut 41,42 is articulated on the top supporting rod 2, and the other end then is articulated in respectively on the side support bar 3 of top supporting rod 2 both sides; Hinged more smooth and easy for making, respectively be provided with a connecting seat 6 on the side support bar of both sides, the other end of strut 41,42 then is articulated on this Connection Block 6.
As shown in Figure 4, it is another embodiment of the present utility model, and the other end of described strut 41,42 also can directly be articulated on the sliding seat 5 of side support bar 3 ends, perhaps is articulated on the sliding seat 5 of side support bar 3 ends (as shown in FIG.) by Connection Block.
Because support bar 4 is set to independently two struts 41,42 in of the present utility model, and the other end of this two strut 41,42 is articulated on the side support bar 3 of both sides correspondence, tent strut frame upon deployment, described two struts 41,42 are positioned at different planes with top supporting rod 2, and the formation gusseted, so integrated support is not quite firmly rocked.
In addition, the utility model is when folding, and side support bar 3 is the 4 inside foldings of support bar in the direct pull, and need not pass through sliding seat 5, so the power that sliding seat 5 is born is much smaller relatively, and support bar 4 pulling force are also relatively large in acting on, thereby make folding easier.
