DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the following will be described clearly and completely in combination with the technical solution in the embodiments of the utility model. Obviously, the described embodiments are partial embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0025] A foldable storage bag that is easy to seal and lift according to a preferred embodiment of the utility model; Figure 1-4 As shown, the storage bag is formed by the front side 10 of the storage bag and the rear side 11 of the storage bag. The bottom of the front side and the rear side of the storage bag are connected by a folding part 12. The top is provided with a mouth 13. The front side and the rear side of the storage bag enclose a storage cavity 14 for placing objects. The upper ends of the front side and the rear side of the storage bag are provided with a locking assembly 14. The mouth is opened or closed by a locking assembly 15, so that objects can be placed in or taken out of the storage cavity. The locking assembly 15 is connected to the front side and the rear side of the storage bag through an arc-shaped connecting part 16.

[0026] Specifically, Figure 2As shown, the folding portion 12 includes a folding bottom 120 and a folding side 121 integrally formed with the folding bottom. The folding bottom connects the front side of the storage bag and the bottom of the rear side of the storage bag. The folding side 121 connects part of the front side of the storage bag and the side of the rear side of the storage bag. The folding bottom and the middle of the folding side are both provided with a folding edge 123. The folding bottom and the folding side can be folded through the folding edge to fold the folding storage bag, or the folding storage bag can be opened through the folding edge to reduce the volume of the folded storage bag, save space, and facilitate the transportation and placement of the folding storage bag. At the same time, due to the provision of the folding side, the storage cavity is larger in volume after opening, and more items can be placed.

[0027] Furthermore, if Figure 1-2 As shown, the folding part 12 is connected to the front side 10 of the storage bag and the back side 11 of the storage bag through a fixing part 17, and the fixing part includes a fixed connection part 170 and a movable connection part 171. The fixed connection points of the front side and the back side of the storage bag form a fixed connection part at the side, the connection between the front side of the storage bag and the folded side part forms a movable connection part 171, and the connection between the back side of the storage bag and the folded side part also forms a movable connection part 171. The length of the movable connection part can be determined by adjusting the position of the connection point of the fixed connection part at the front side of the storage bag and the back side of the storage bag, so that the volume of the storage cavity is further increased. In the present utility model, the fixed connection part is set at the middle position of the storage bag. It should be noted that the change in the position of the fixed connection part so as to change the length of the movable connection part and thus change the volume of the storage cavity should belong to the protection scope of the present utility model. At the same time, in order to make the connection between the front side 10 of the storage bag and the back side of the storage bag more stable, the fixing part 17 is set to an outer convex column shape, so as to provide a greater load-bearing capacity for the storage bag. The folding portion can be folded or opened through the relative or back-to-back movement of the movable connection portion 171, which facilitates the opening and folding of the storage bag.

[0028] Furthermore, if Figure 1-2 and Figure 4 As shown, the arc surfaces of the two sets of arc-shaped connecting parts 16 are arranged opposite to each other, and the arc angle of the arc surface is less than 90 degrees, thereby enhancing the sealing of the foldable bag. The arc-shaped connecting parts also facilitate the kneading of the foldable storage bag after closing, and the arc-shaped connecting parts can increase the contact area with the hand, making it convenient to lift the foldable storage bag without providing a handle.

[0029] Furthermore, if Figure 1-3As shown, the locking assembly 15 includes a first locking wall 150 connected to the front side 10 of the storage bag, and a second locking wall 151 connected to the rear side 11 of the storage bag. The first locking wall is provided with a locking strip, and the second locking wall is provided with a locking groove 154. The locking strip is inserted into the locking groove to lock the locking assembly, thereby closing and sealing the mouth of the storage bag. The first locking wall 150 and the second locking wall 151 are provided with contact surfaces 155 on the opposite sides. When the locking assembly is locked, the adsorption between the contact surfaces also enhances the sealing of the folding bag. A concave portion 152 is provided on the side of the contact surface away from the storage cavity, and a gap is left between the two groups of concave portions, so that it is convenient to pull the contact surfaces apart and continue to pull apart to unlock the locking assembly.

[0030] Furthermore, if Figure 4 As shown, the locking strip 153 is provided with a connecting column 1531 on the contact surface, and a sealing column 1530 is provided at the end of the connecting column. A first stopping column 1532 extending outward is formed on the upper and lower sides of the sealing column, and the distance between the two groups of first stopping columns is greater than the thickness of the connecting column. The locking groove 154 is provided with an insertion groove 1540 corresponding to the sealing column, and a first sealing groove 1541 connected to the insertion groove. After the sealing column is inserted into the insertion groove, it is squeezed and continuously enters the first sealing groove to lock the locking assembly. At this time, the connecting column is placed at the insertion groove, and second stopping columns 1542 are correspondingly provided at both ends of the insertion groove. A stopping force is generated between the first stopping column and the second stopping column, so that the sealing effect of the folding belt after locking is better, and due to the stopping force between the first stopping column and the second stopping column, a moving pulling force needs to be applied to unlock the locking assembly. In order to further increase the tension and sealing of unlocking, the end of the arc-shaped connecting part 16 connected to the locking strip 153 is provided with an outer edge end 161, and a second sealing groove 156 is formed between the upper part of the outer edge end and the connecting column 1531 and the lower first stop column. When the sealing strip is inserted into the sealing groove, the lower second stop column 1542 and the smooth end 161 enter the second sealing groove 156, so that the sealing of the folding storage bag is stronger and the tension required to open it is greater. It should be noted that since the locking component needs to deform during the locking and unlocking process, the material of the folding storage bag should be silicone material, which can be restored after a certain deformation, and the folding storage bag can be molded by one-piece molding.

[0031] It should be understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application belong to the scope protected by the present invention.
