Abstract

The utility model discloses a telescopic material holding tube which can be folded and extended. A spiral elastic metal bar(1) and a frame are wrapped by two clipping layers of a tube-shaped bag which matches with the size of the frame and is made of a double-layer soft material(2). The clipping layers beside the metal bar are sewed together so that the metal bars are positioned inside the sewing thread. The opening of the material holding tube is connected with a cover(3) made of the same material, and the upper and the lower rims of the sidewall of the material holding tube are correspondingly fixed with two buckles(4,5) which can be interlocked with each other. The material holding tube of the utility model can be folded with a flat shape and a compacted volume when out of use, which facilitates the carrying, storage, simplifies the production and lowers the use cost. The utility model can be widely used for holding and turning over the materials of the garbage cans in parks and residential districts or during the process in the textile enterprises.

Description

Flexible storage tube

The utility model relates to a kind of cylindrical container that holds article, specifically a kind of flexible storage tube that can be shrunk to offset flat shape.

Need hold the cylindrical container nothing to be surprised at of article in the daily life temporarily, lose the rubbish shoot of collecting sorting rubbish in leaf or the residential quarter such as collecting residual branch in the park, in the light textile enterprise material course of processing, half-blank holds, the material container tube that shifts etc., the at present this storage tube that is using in a large number, basically be solid shape, the material of making has made of ironly also has the cardboard ironware compound, cost of manufacture is higher relatively, the empty tube when running condition not, the storage tube that volume is big more, its volume shared in the space is also big more, and this just makes the storage tube strengthen in circular flow hollow carrying throughput rate.

The purpose of this utility model provides a kind of storage tube of variable-volume, and it has enough big volume to hold article during normality, and empty tube shifts, and is retractable into flats during storage.

For reaching above-mentioned purpose, flexible storage tube of the present utility model, what comprise that support frame and double-deck flexible material are made uncoveredly has an end cylindrical shell, spiral fashion resilient metal strip skeleton is wrapped in the interlayer of the double-deck flexible material cylindrical shell that coincide with the skeleton framework, the double-deck flexible material of helical metal bar both sides is sewed up, the spiral fashion resilient metal strip is positioned in the two sutural interlayers the last lower edge of flexible material cylindrical shell, the corresponding fixing lockable button of climbing; The uncovered edge of cylindrical shell connects the cover that same material is made, and cylindrical shell is connected folding with cover with slide fastener.

The utility model is owing to be skeleton with the spiral fashion resilient metal strip, the storage tube is when normality, the formed framework of skeleton supports the cylindrical shell of double-deck flexible material, make it to become cylindrical container with a constant volume, transportation, in the collection process, when not needing it to have container function, as long as the storage tube is compressed from top to bottom, spiral fashion resilient metal strip skeleton compresses thereupon, flexible material between the bonding jumper is folding, the cooresponding up and down padlock of climbing of tube side is fixed, can make the very big storage tube of original volume dwindle into flats, be convenient to shift, transportation, collection, simultaneously, it to have cost of manufacture cheap, damage at the bottom of the barrel tube and change conveniently, can repeat nonexpondable advantage.

Fig. 1 is a three-dimensional structure diagram of the present utility model.

Fig. 2 is the utility model confined state block diagram.

Fig. 3 is the three-dimensional structure diagram of the utility model cross-sectional plane different conditions.

The utility model is described in further detail in conjunction with the embodiments with reference to the accompanying drawings.

Shown in Figure 1, the cylindric framework (1) that spiral fashion resilient metal strip skeleton forms, be wrapped in the interlayer of the tube-shape bag (2) that the double-deck flexible material that coincide with cylinder-shaped frame makes, metallic framework rigidity steel wire coiling spiral coil, comprise, following two annulus are five circles, the double tubular bag is made with synthetic leather and is formed, the double tubular sackholder layered suture of bonding jumper both sides closes, spiral fashion resilient metal strip (1) is positioned in the sutural interlayer, with the uncovered cover that matches of the storage tube that supports by spiral fashion resilient metal strip skeleton (3), be attached thereto with identical synthetic leather material, the connection slide fastener is sewed up at the edge of cover (3) and the uncovered edge of cylindrical shell, make it folding freely, the last lower edge of cylindrical shell side, correspondence position connects respectively, and what can connect locking climbs button (4,5).The spiral elasticity bonding jumper can turn to cross-sectional plane ellipse, square, oblong and vertical section respectively and be down trapezoidal skeleton framework, the tube-shape bag made from the double-deck flexible material that coincide with difformity skeleton framework is combined into round erect cylinder, oval column shape, positive box type column shape, the flexible bag of rectangular column shape, taper type.
