The utility model adopts following technical scheme to realize: a kind of folding-type portable rack, this rack comprises: at least two folding tripods that spacing arranges, each folding tripod comprises first support bar and second support bar that is X-shaped or cross oblique crank Z connection setting, and the lower end of first support bar of each folding tripod is hinged by a L shaped brace and a vertical rod respectively; Between many vertical rods, by a L shaped brace connection cross bar is set, on two ends of cross bar, connect the one group of push rod that comprises first push rod and second push rod by T shape brace respectively, and between first push rod and the cross bar and between second push rod and the cross bar position-limit mechanism is set respectively.
Wherein, on two first support bars of outermost two folding tripods between the end and two second support bars of outermost two folding tripods on connect respectively between the end fixed bar be set, the frame cloth of placing article is set between fixed bar, is connected with foot piece respectively at two ends of frame cloth.
Wherein, position-limit mechanism is by first banking stop and second banking stop is hinged forms, first end of first banking stop is hinged on first push rod or second push rod, and second terminal second end with second banking stop of first banking stop is hinged, and first end of second banking stop is hinged on the cross bar; Second end at first banking stop arranges recess, and second terminal go up setting and can be connected to extension among the recess of second banking stop.
Wherein, vertical rod is made of at least two branch bars, scalable connection between adjacent minute bar.
Compared with prior art, the utlity model has following beneficial effect:
1, is provided with the position-limit mechanism that can limit the vertical rod moving position, guaranteeing to have strengthened the entire firmness of rack on the basis that stand is convenient to fold, also guaranteed the stable of stand.2, vertical rod is made of at least two branch bars, and the convenient mobile demand of client to rack satisfied in scalable connection between adjacent minute bar; 3, folding tripod adopts X type or the cross that axle connects, easy accessibility, and volume after folding is less, and very portable.4, at two vertical rod tops in the rack outside folding push rod structure is set, can occlusion part (such as waterproof cloth) be set in push rod structure, thereby the article on the convenient protection rack are user-friendly to.
Description of drawings
Fig. 1 is the structural representation of the utility model first embodiment;
Fig. 2 is the schematic diagram of the utility model push rod and cross bar syndeton.
The specific embodiment
The utility model proposes a kind of employing folding-type portable rack, have the characteristics of sound construction, convenient disassembly.
As shown in Figure 1, the portable rack that the utility model proposes comprises: three folding tripods, be provided with spacing between the adjacent folds foot rest, this folding tripod comprise be X-shaped or cross oblique crank Z connect first support bar 1 that arranges and second support bar, 2, the first support bars 1 and second support bar 2 can be movable; Wherein second support bar 2 comprises the two parts 21 and 22 that connected by bending brace 23, and first support bar 1 is connected setting with 23 of braces of bending; The lower end of first support bar 1 of each folding tripod is hinged by a L shaped brace 51 and a vertical rod 3 respectively, and vertical rod 3 vertical grounds (or the plane of placing rack) arrange; Between many vertical rods 3, also by L shaped brace 51 connections a cross bar 8 is set, will be connected together between the adjacent folding tripod by L shaped brace 51 by cross bar 3; Between first support bar 1 of each folding tripod and corresponding vertical rod 3, be provided with the position-limit mechanism that is constituted by the first hinged banking stop 61 and second banking stop 62; On two ends of cross bar 8, connect the one group of push rod that comprises first push rod 91 and second push rod 92 by T shape brace 53 respectively; On 2 first support bars 1 of outermost 2 folding tripods between the end and 2 second support bars 2 of outermost 2 folding tripods on connect respectively between the end fixed bar be set, the frame cloth 7 of placing article is set between fixed bar, two ends at frame cloth 7 are connected with foot piece 4 respectively, can prop up frame cloth 7 like this, the outward appearance better appearance can be placed on the end of fixed bar within the frame cloth 7.
