[0027] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] Example 1

[0029] like Figures 1 to 4As shown, a bag described in this embodiment comprises an upper box shell 1 and a lower box shell 2, and side box surfaces 3 connected to the upper box shell 1 and the lower box shell 2 are respectively provided between the upper box shell 1 and the lower box shell 2, and the upper box shell 1 and the lower box shell 2 are respectively provided with mounting portions 50 for inserting rods 4. In this embodiment, the rods 4 can support the upper box shell 1, so it has a certain rigidity; the side box surfaces 3 are made of flexible material, and the upper box shell 1 and the lower box shell 2 are connected by a plurality of rods 4. Preferably, the number of rods 4 is at least 4, and the four rods 4 can form a three-dimensional space. An elastic member 5 is provided between the rod 4 and the upper box shell 1 or / and the lower box shell 2, and the elastic member 5 can be adjusted on both sides of the rod 4 as needed. The ends of the rod 4 are all arranged or only arranged at one end of the rod 4, and the elastic member 5 is arranged at the installation portion 50; in this embodiment, the installation portion 50 can be a cylindrical cavity or a cavity surrounded by a plurality of discrete ribs. The above embodiments can all achieve horizontal limitation of the rod 4, and the elastic member 5 arranged there can also be limited, which is convenient for installation; when no external force is applied to the elastic member 5, the sum of the length dimensions of the elastic member 5 and the rod 4 is greater than the installation length between the upper box shell 1 and the lower box shell 2, and the length dimension of the rod 4 is less than the installation length between the upper box shell 1 and the lower box shell 2; the installation length is the distance between the upper box shell 1 and the lower box shell 2 where the rod 4 is installed when the rod 4 is installed between the upper box shell 1 and the lower box shell 2 and the side box surface 3 is tightened. If the length of the rod 4 is too long, the installation of the rod 4 cannot be achieved after the side box surface 3 has been tightened; if the length of the rod 4 is too short, the side box surface 3 cannot be tightened when the rod 4 and the elastic member 5 are against each other. When the bag is assembled, one end of the elastic member 5 is against the upper box shell 1 and / or the lower box shell 2, and the other end of the elastic member 5 is against the rod 4. When the bag is assembled, the elastic member 5 needs to be compressed first so that the rod 4 can be installed between the upper box shell 1 and the lower box shell 2. After the rod 4 is installed, the elastic member 5 applies a force to the rod 4 to make the upper box shell 1 and the lower box shell 2 tend to move away. In this embodiment, the length of the elastic member 5 and the rod 4 is suitable. The elastic member 5 needs to be compressed before the rod 4 can be installed between the upper box shell 1 and the lower box shell 2. After the elastic member 5 rebounds, the length of the elastic member 5 and the rod 4 increases, tightening the flexible material to form a suitable side box surface 3.

[0030] In this embodiment, a side plate 6 is provided between two adjacent rods 4, and the side plate 6 is made of plastic or metal material, and is arranged on the inner side of the side box surface 3. Since the side box surface 3 is made of flexible material, the side plate 6 made of plastic or metal material has a certain rigidity, so that the side box surface 3 is prevented from bulging outwards when the bag is filled with clothes.

[0031] In this embodiment, the two ends of the side plate 6 are respectively sleeved on two adjacent rods 4. Through holes are provided at both ends of the side plate 6, and the rods 4 are inserted through the through holes and sleeved to connect. By sleeved, the side plate 6 and the rods 4 can be firmly connected and have strong lateral force.

[0032] In this embodiment, the side plate 6 includes a rear side plate 61, a left side plate 62 and a right side plate 63, and the rod 4 includes a first rod 41, a second rod 42, a third rod 43 and a fourth rod 44, and the first rod 41, the second rod 42, the third rod 43 and the fourth rod 44 are distributed in a 4-point rectangular shape, one end of the left side plate 62 is connected to the first rod 41, and the other end of the left side plate 62 and one end of the rear side plate 61 are jointly arranged on the second rod 42, one end of the right side plate 63 is connected to the fourth rod 44, and the other end of the right side plate 63 and the other end of the rear side plate 61 are jointly arranged on the third rod 43. In this structure, the side plate 6 is split, and the manufacturing efficiency and manufacturing cost are greatly reduced. Although it is a split structure, the sleeve installation method does not reduce the lateral force.

[0033] In this embodiment, a handle 7 is also included, and the handle 7 is arranged on the left side plate 62 and / or the right side plate 63. The mounting structure uses the left side plate 62 and / or the right side plate 63 as a mounting platform for the handle 7, and no mounting position is required for the handle 7.

[0034] In this embodiment, the upper box shell 1 is provided with a storage chamber 8, and the opening of the storage chamber 8 is provided with a cover body for covering the opening. The storage chamber 8 is a concave cavity on the upper box shell 1, or a cloth pocket provided on the upper box shell 1. The storage chamber 8 has an opening for storing and taking out articles, and a cover body for closing the opening is provided at the opening. Preferably, the cover body includes a cover cloth, and a zipper is provided between the cover cloth and the storage chamber 8; another embodiment is that the cover body is a plastic plate, and the plastic plate can cover the opening.

[0035] In this embodiment, a reinforcement member 11 is provided on one side of the upper case shell 1 close to the bag opening, and the reinforcement member 11 is provided along the width direction of the bag. Existing bags all have an opening for taking and placing items, and the opening is the bag opening. The reinforcement member 11 can be directly formed on one side of the upper case shell 1 close to the bag opening during manufacturing, or it can be assembled later. Because the bag opening is at the front / back of the bag, the reinforcement member 11 is provided along the width direction of the bag to reinforce the force reduced by the opening.

[0036] In this embodiment, the reinforcement member 11 is a fifth rod member, and the fifth rod member is fixedly connected to the upper box shell 1 .

[0037] In this embodiment, the rod 4 is a hollow structure. Compared with a solid tube, a hollow tube has less stress loss, but is lightweight and can reduce the weight of the bag.

[0038] In this embodiment, the rod 4 is made of glass fiber material, aluminum alloy material or plastic.

[0039] In this embodiment, two recessed portions 20 are provided below the lower case 2, and a rib 21 protruding from the recessed portions 20 is provided between the two recessed portions 20, and the rib 21 extends along the width of the case. The two recessed portions 20 can enhance the load capacity of the lower case 2, and the rib 21 can further enhance the load capacity. When moving the case, the rib 21 can serve as a hand grip, achieving multiple goals at one stroke.

[0040] In this embodiment, the flexible material is a textile or a plastic film, or a combination of a textile and a plastic film.
