Abstract

A folding type draw-bar box comprises an extensible draw bar arranged at the box bottom and rollers arranged at one end of the box bottom. Folding boards capable of being fold horizontally inside the box bottom or being fold vertically outside the box bottom are arranged at the periphery of the box body walls. At least an upper folding board and a lower folding board parallel to each other are arranged in any side wall. The upper folding board and the lower folding board are respectively arranged in an upper lining bag and a lower lining bag which are connected vertically and separated by parallel seam lines in the middle. An upper edge of an outer fiber cloth layer of each corresponding long edge is provided with a piece buckle belt cloth movably connected with the upper lining bag. According to the folding type draw-bar box, volume of a box body can be changed according to using requirements. When the volume needs to be enlarged, the two corresponding long edges are turned to be vertical from horizontal positions and then a vertical zipper buckle belt is tightened. When the volume needs to be shrunk, two upper folding boards of the two corresponding long edges are fold inwards to be horizontal, short edges are fold inwards on the long edges so that the volume of the box body can be decreased by half and therefore folding type draw-bar box is convenient to carry in use or place when not in use.

Description

Collapsible draw-bar box

Technical field

The utility model relates to a kind of tourism case and bag, is specifically related to a kind of foldable draw-bar box.

Background technology

At present, draw-bar box is more for travelling, all is deposited in together as idle article in time spent not, because draw-bar box volume when idle is larger, has accounted for larger place, space.Even at whilst on tour, few when many during article going along with, when object was few, box volume was still constant, give to carry and deposit and all bring inconvenience, so a kind of draw-bar box that can adjust according to the use needs box volume, the necessity that seems and fashion.

Summary of the invention

The utility model designs a kind of folding draw-bar box for present draw-bar box above shortcomings, can be according to using needs to change tank-volumes, and convenient use or idle stack.

Design of the present utility model is, collapsible draw-bar box, it comprise be located at the telescopic bar at the bottom of the case and be located at case at the bottom of the roller of an end, it is characterized in that: establish around the box body wall be converted in can be at the bottom of the case level or outside be converted into upright flap, at least establish two blocks of parallel upper and lower flaps in arbitrary sidewall, in the upper and lower lining bag of being separated by parallel suture in the middle of upper and lower flap is contained in respectively up and down and links to each other, the outer fiber layer of cloth upper limb on corresponding long limit establish one with the cingulum cloth of upper lining bag flexible connection.

Described casing two corresponding minor faces are established with tank-volumes and are changed and length-adjustable fastening tape.

The upper flap infolding on the corresponding long limit of described casing formerly, the upper flap infolding of corresponding minor face is rear.

Establish the slide fastener that three limits link to each other on the described case lid.

Vertical height of described upper flap is 2～3 times of lower flap portion.

The beneficial effect of above-mentioned design is and can when enlarging volume two corresponding long limits upwards be turned into uprightly by horizontal level according to using needs to change the volume of casing, and upright slide fastener cingulum tension is got final product.First the upper flap on two corresponding long limits inwardly is converted into horizontally in the time of need dwindling volume, the minor face infolding can be reduced to half with tank-volumes on long limit, and convenient the use carried or idle stacks.

The specific embodiment

Below in conjunction with accompanying drawing the utility model embodiment is further specified.

Referring to Fig. 1 and shown in Figure 3, draw-bar box by casing 11, be located at the bottom of the case 1 expansion link 10, be located at that the roller 9 of 1 one ends forms at the bottom of the case.1 is supported by box body wall with case lid 5 at the bottom of the case, and box body wall is comprised of outer fiber layer of cloth, middle hard layer and liner fiber cloth, and case lid 5 only forms soft lid by inside and outside fiber cloth.Middle hard layer is flap, at least establish two blocks of parallel upper and lower flaps in arbitrary sidewall, on first on the flap 7 or second flap 3 and the first lower flap portion 8 or the second lower flap portion 2 be contained in respectively in the upper and lower lining cloth bag of being separated by parallel suture in the middle of linking to each other up and down, so that the upper flap around the box body wall can be in a horizontal position to 1 infolding at the bottom of the case.Left and right sides wall is the long limit of casing, the outer fiber layer of cloth upper limb on corresponding long limit is established a cingulum cloth 13 that is flexibly connected with upper lining bag, when the upper lining bagging on long limit and cingulum cloth 13 during by magic glue chain 15 fastening, on first on the flap 7 or second flap 3 and the first lower flap portion 8 or the second lower flap portion 2 stand vertically with the case bottom surface, tank-volumes expands to maximum, on first on the flap 7 or second vertical height of flap 3 be the first lower flap portion 8 or the second lower flap portion 2 2～3 times, such as Fig. 3 and shown in Figure 5.Lining cloth 14 on the pull bar 10 at the bottom of the case in 1 is used for isolation, makes not tension member expanding-contracting action impact of article.Also establish the slide fastener 4 that three limits link to each other on the

case lid

5,11 liang of relative short end of casing are also established with box volume and are changed and length-adjustable fastening tape 6.

Referring to Fig. 2 and shown in Figure 4, when needs dwindle tank-volumes, at first take the adhesion of casing 11 outer fiber layer of cloths and cingulum cloth 13 apart, again with long limit about casing first on flap 7 infoldings in the middle of the casing 11 turn over, about making on first of long limit flap 7 be tiled on the case bottom surface, and then with the front and back end minor face second on flap 3 turn over to infolding, namely on first of corresponding long limit flap 7 infoldings formerly, corresponding minor face second on flap 3 infoldings rear.Pull on slide fastener 4 and tension fastening fastening tape 6 on case lid three limits, advance telescopic lever 12, namely become flat draw-bar box as shown in Figure 2, box volume dwindles below 1/2 at least, convenient folding the placement, and effective conserve space, and can carried by handle 12.
