Abstract

The utility model relates to a tent frame, which is characterized in that a frame body is composed of more than three groups of U-shaped frames, wherein two vertical rods and transverse rods of the U-shaped frames are hinged together by a connecting piece, and the lower ends of the vertical rods of the same side of the U-shaped frames are hinged together by a foot disc. When the utility model is folded, a plurality of groups of U-shaped frames can be overlapped together along the foot disc, and the vertical rods of the two sides can be folded back onto the transverse rods to be overlapped. When the utility model is unfolded, the U-shaped frames are in radiation shape along the foot disc; thus, a tent cloth can be supported in a relative large range to provide a large service space. The tent frame has the characteristics of simple folding and unfolding operations, and portable and stable whole body. Thus, the utility model can be widely matched with a tent and a mosquito net.

Description

The tent support

The utility model belongs to small stores, particularly a kind of tent support that is used to support tent or mosquito net.

Tent uses in industries such as march camping, field work, Travel Adventures in a large number.The tent structure comprises tent support and paulin mostly, paulin adheres to be fixed on the support and forms, supporting structure is varied, substantially all be folding, there be also having of clumsiness light and handy, two parts of tent patents are disclosed in patent gazette, a for the patent No. is 94215286.7, portable and collapsible tent by name, the similar umbrella of its supporting structure, there is a head tree at the middle part, and the logical keel haul line in each support bar end fuses, but with the same folding of umbrella, but the unique not enough place of this support is that a head tree is arranged, at the tent middle part, taken the optimum position, made originally to seem just littler with regard to little tent; And the patent No. is 97224182.5, folding tent skeleton by name, its skeleton comprises column, goes up ceiling hold and supports grid, ceiling hold is hinged on each column and, fuse through supporting grid between each column and ceiling hold, support grid and in skeleton, play crucial effect, and the network complexity, and infinite place, the fluffy skeleton of account has the possibility of folding at any time.

The purpose of this utility model is to overcome the deficiencies in the prior art, designs a kind of convenient folding, the tent support of supporting ﹠ stablizing.

Task of the present utility model is achieved in that a kind of tent support, it is characterized in that rack body is made up of " door " shape frame more than three groups, two montants and the cross bar of " door " shape frame are hinged through brace, and each " door " shape frame homonymy montant lower end one pin dish is hinged.Organizing " door " shape frame during folding can overlap along the pin dish more, the both sides montant can be along the pin joint inflection of montant and cross bar, stack up to montant is parallel with cross bar, whole one-tenth one tabular, and when opening along pin dish radial, can support cloth of tent or mosquito netting in a big way, and overhang a bigger space in " door " shape frame for using.

The utlity model has reasonable in design, folding and strut simple to operate, whole solid and reliable, and provide maximum usage space, each montant of " door " shape frame and cross bar adopt expansion link, can organically adjust the size of tent support, can extensively be matched in tent, use on the mosquito net at home, collection is carried all very convenient.

Below in conjunction with concrete legend the utility model is described further:

Fig. 1 tent support is opened schematic diagram

Fig. 2 " door " shape frame folding schematic diagram

Fig. 3 expansion link schematic diagram

With reference to Fig. 1, a kind of tent support, its rack body is made up of " door " shape frame 1 more than three groups, among the figure be five groups, two montants 2 of " door " shape frame 1 are hinged through brace 4 with cross bar 3, and each " door " shape frame 1 homonymy montant 2 lower ends one pin dish 5 is hinged, when opening from pin dish 5 radials, the outer semi arch shape that forms, when the montant 2 and the cross bar 3 employing expansion links of " door " shape frame 1, promptly the profile of support also can become rectangular-shaped or other shape.Be hinged with banking stop 6 by 2 of pin dish 5 places adjacent " door " shape frame 1 montants, the position that each " door " shape frame 1 is opened is defined, and further improves whole stability; Or be provided with spacing rope at 3 of the cross bars of adjacent " door " shape frame, show it with dotted line among the figure.

With reference to Fig. 2, the schematic diagram during 1 folding of " door " shape frame, the montant 2 of both sides can turn back and cross bar 3 parallel stacking, and more economize local; Dotted line is represented the state that two montants 2 have not folded.

With reference to Fig. 3, the montant 2 and the cross bar 3 of " door " shape frame 1 can adopt expansion link, the positioning relation of expansion link as shown, interior bar 7 surfaces are provided with protruding pearl 9, are headed on by built-in spring 10, when protruding pearl 9 is walked to the shrinkage pool 11 of outer bar 8, hold out against spacing, when external force was stretched or compressed inside and outside

bar

7,8 hard draw, spring 10 shrank in the protruding pearl 9 and contracts to interior bar 7 surfaces, and stretching and compression are carried out.The detent mechanism of expansion link also can adopt other way, just no longer describes in detail here.

Claims

1, a kind of tent support is characterized in that rack body is made up of " door " shape frame more than three groups, and two montants and the cross bar of " door " shape frame are hinged through brace, and each " door " shape frame homonymy montant lower end one pin dish is hinged.

2, tent support according to claim 1 is characterized in that the montant and the cross bar of " door " shape frame is expansion link.
