Detailed Description

In order to facilitate the understanding of the technical solutions of the present invention for those skilled in the art, the technical solutions of the present invention will be further described with reference to the drawings attached to the specification.

First, the bag body according to the present embodiment is a storage bag that can be a backpack, a rucksack, a handbag, or other common shape type. In the present embodiment, a backpack is taken as an example for explanation, and it is needless to say that, in the technical solution of the present invention, a solution that is simply replaced and improved is also within the protection scope of the technical solution of the present invention, such as a structure that the same or similar supporting plate and traveling wheels in the technical solution are installed at the bottom of a general handbag. The following embodiment takes a backpack as an example, according to the conventional backpack habit of people, the back surface facing the back of the human body is the back surface and the back surface of the backpack body, the opposite surface is the front surface, the upper surface of the general backpack is provided with an opening, and the lower surface is the bottom surface.

As shown in fig. 1 and 3, the present invention relates to a variable volume travel bag, which comprises a bag body 1 having a folding portion 15, a support tray 2 disposed at the bottom of the bag body 1, and a travel roller 22 mounted on the support tray 2. The supporting plate 2 is L-shaped and comprises a supporting bottom plate 21 arranged at the bottom of the bag body 1 and a limiting plate 23 fixedly connected to one side of the supporting bottom plate 21 and arranged at the back of the bag body 1. The walking roller 22 is arranged at the side edge position of the supporting bottom plate 21 close to the limit plate 23.

Based on above-mentioned technical scheme, will wrap body 1 and arrange support plate 2 in and fixed, can realize the walking that drags of large capacity package body, avoid the problem of shoulder back of the body, avoid the pressure of the heavier package body of large capacity, weight to shoulder and waist, reduced the intensity of carrying luggage. Simultaneously, the setting of support plate 2, the carrier can realize arranging the package body in subaerially, avoids the bottom of package body 1 to be polluted.

As shown in fig. 5 and 6, the supporting bottom plate 21 includes a first plate 211 and a second plate 212 detachably connected, the first plate 211 and the second plate 212 are arranged side by side along the front and rear direction of the bag body 1, and during dragging of the bag body, the first plate and the second plate move synchronously, so that the problem of separation and detachment does not occur, and the stability is good. Limiting plate 23 rigid coupling is kept away from on the side of first board 211 in second board 212, and the setting of limiting plate 23, better realization support plate 2 fixed with package body 1, realized package body and support plate 2's relatively fixed, avoid the in use to appear breaking away from or the problem of skew.

As shown in fig. 5 and 6, the side of the first plate 211 close to the second plate 212 is provided with a connecting arm 214 corresponding to the left-right direction of the bag body 1, the second plate 212 is provided with a connecting groove 215 corresponding to the connecting arm 214, and the second plate 212 is detachably connected with the first plate 211 through the connecting groove 215 and the connecting arm 214. The structure has the advantages that the first plate and the second plate are connected and are convenient to install, the first plate and the second plate move synchronously, the problem of separation and separation cannot occur, and the stability is good.

As shown in fig. 5 and 6, the limit plate 23 and the second plate 212 are fixedly connected to the side far away from the first plate 211, and the limit plate 23 and the second plate 212 are integrally formed to enhance the strength thereof, so that the problems of breakage or breakage do not occur. The supporting support plate 2 and the limiting plate 23 can be formed by direct foaming of EPP, EPO and the like, can be formed by materials such as PE, PP, PVC and the like, and have the advantages of light weight, low cost and good strength.

A third plate 213 is detachably attached to the side of the first plate 211 remote from the second plate 212. Supporting baseplate 21 adopts the concatenation of multiple boards, convenient to detach, when the package body is in little volume, directly wears on the back, does not need supporting plate 2's use, can carry out the split to supporting plate 2 this moment, and the split is the less state of size, then directly accomodates at this internal, convenient to carry of package.

A plurality of long round holes 216 are respectively formed in the first plate, the second plate, the limiting plate and the third plate, the long round holes 216 are arranged, and the bag body is fixed to the supporting plate 2 in cooperation with the connecting ropes and the like at corresponding positions on the bag body. The width of the supporting bottom plate 21 in the front-back direction of the bag body is larger than the width of the bag body in the front-back direction, so that the complete support of the holding body is realized, and the influence on the cleanness of the bag body caused by the fact that a part of the bottom of the bag body falls on the bottom surface is avoided.

As shown in fig. 1 to 3, the bag body 1 includes an upper bag body 11 and a lower bag body 12, and the folding portion 15 includes a cylindrical cloth tube 150 with a cross section adapted to the cross section of the bag body. Two ends of the columnar cloth cylinder 150 are fixedly sewed with the bottom end of the upper bag body 11 and the top end of the lower bag body 12 respectively. The outer side surface of the bottom end of the upper bag body 11 and the outer side surface of the top end of the lower bag body 12 are respectively provided with a letter zipper 14 and a letter button 13 which are matched with each other. When a small-capacity bag body is needed, the columnar cloth tube 150 is folded according to the state of figure 2, rolled up and fixed according to the arrow direction, and then the letter zippers 14 and the letter buttons 13 are respectively matched and fixed, so that the small-capacity bag body is obtained and is convenient to carry.

As shown in fig. 2, the tether 17 is respectively disposed on the inner side surface of the bottom end of the upper bag body 11 and the inner side surface of the top end of the lower bag body 12, the tether 17 folds and fixes the cylindrical cloth tube 150, as shown in fig. 2, the cylindrical cloth tube 150 is folded in a rolling manner according to the arrow direction in fig. 2, and then the two tether 17 are connected, so that the fixation of the cylindrical cloth tube 150 is realized, and the influence of scattering and falling surfaces on the storage in the folding process is avoided.

In the technical scheme, the bag body is a backpack with two shoulders and a single shoulder or a handbag, and the top of the bag body 1 is provided with a pull ring 16. The setting of pull ring 16, when the package body is arranged in support pallet 2 under the large capacity state on, can manually stimulate pull ring 16, drag the package body and walk with support pallet 2 under walking gyro wheel 23 rolls, the carrying and the transport of the package body of the large capacity of being convenient for.

Technical solution of the invention is described above with reference to the accompanying drawings, it is obvious that the specific implementation of the invention is not limited by the above-mentioned manner, and it is within the scope of the invention to adopt various insubstantial modifications of the inventive method concept and technical solution, or to apply the inventive concept and technical solution to other occasions without modification.
