[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0029] Example 1 This embodiment discloses a foldable storage bag frame, such as Figure 1 and Figure 8 As shown, the frame structure mainly consists of three parts: side frame 1, fixed frame 2, and base frame 3. The base frame 3 provides the bottom support; the side frames 1 are provided in two sets, symmetrically distributed on both sides of the long side of the base frame 3; the fixing frames 2 are provided in two sets, symmetrically distributed on both sides of the short side of the base frame 3; the base frame 3, side frames 1 and fixing frames 2 distributed in the above positions together constitute the main structural part of the frame of this foldable storage bag.

[0030] The following is combined Figure 2-5 The specific configuration of the three main structural components of the foldable storage bag frame in this embodiment is described in detail below: First, such as Figure 3 As shown, the side frame 1 adopts a detachable design, including short side frame tubes 16 on both sides and long side frame tubes 12 on the top and bottom. The long side frame tubes 12 and short side frame tubes 16 are assembled and connected at adjacent end positions by single bend joints 13, and then the single bend joints 13 are riveted to the corresponding frame tubes at preset holes to form the overall frame of the side frame 1. A side-opening hinge 17 is fitted onto the long side frame tube 12 located at the bottom edge of the side frame 1. The side-opening hinge 17 is then connected to the long base frame tube 37 of the base frame 3. Mounting holes are reserved on the side-opening hinge 17 and the long base frame tube 37. Rivets 4 are pressed and fixed at the mounting holes. The side-opening hinge 17 enables the side frame 1 and the base frame 3 to be hinged, which satisfies the folding or opening and closing requirements of the side frame 1 relative to the base frame 3.

[0031] Furthermore, side locks 14 are hinged to the short side tubes 16 on both sides of the side frame via positioning rings 15. The positioning rings 15 and side locks 14 are installed together on the short side tubes 16. After reaching the preset position, the positioning rings 15 and the short side tubes 16 are fixedly connected by rivets.

[0032] For example Figure 6 and Figure 7 As shown, the side latch 14 also has a locking groove adapted to the fixed side tube 24 of the fixed frame 2. By setting the side latch 14 with the positioning ring 15, the side latch 14 can complete the rotation action. The locking groove cooperates with the fixed side tube 24 to form a locking structure. It can be seen that by the side latch 14 distributed between the short side frame tube 16 and the fixed side tube 24 adjacent to the side frame 1 and the fixed frame 2, the locking adjustment of the side frame 1 and the fixed frame 2 in the open or closed state can be realized.

[0033] Secondly, such as Figure 4 As shown, the overall frame of the fixing frame 2 also adopts a detachable design, including fixing side tubes 24 on both sides and fixing horizontal tubes 22 at the top and bottom. The fixing horizontal tubes 22 and fixing side tubes 24 of the fixing frame 2 are assembled and connected at adjacent end positions by double-bend joints 23. Similarly, the double-bend joints 23 are riveted to the corresponding frame tubes at preset holes to form the overall frame of the fixing frame 1; For the fixing frame 2, a double-bend joint 23 is used to assemble and connect the fixing side tube 24 and the fixing horizontal tube 22, forming a structure with staggered heights, so as to meet the storage of the protruding side lock 14 and other structures when the foldable storage bag frame is folded up.

[0034] In addition, it should be noted that the side frame 1 is distributed between the two fixed frames 2, so it will not affect the sequential closing operation of the side frame 1 and the fixed frame 2.

[0035] Furthermore, a limiting block 25 is installed on the fixed side tube 24 of the fixing frame 2 to limit the contact with the side frame 1. The limiting block 25 has a groove formed on it to fit the side frame 1 tube. For example... Figure 8 As shown in the diagram, when the foldable storage bag frame is in the open state, the limiting block 25 abuts against the short side frame tube 16 of the side frame 1 to prevent excessive opening; Figure 8 As shown in the folding diagram, when the foldable storage bag frame is in the folded state, the limiting block 25 abuts against the long side frame tube 12 of the side frame 1 to achieve good folding.

[0036] Furthermore, such as Figure 5 As shown, the overall frame of the base frame 3 also adopts a detachable design, including short base frame tubes 34 at the front and rear positions and long base frame tubes 37 on both sides. The long base frame tubes 37 and short base frame tubes 34 of the base frame 3 are assembled and connected at adjacent end positions by single-bend joints 13 (with the same structure as the single-bend joints 13 of the side frame 1). Similarly, the single-bend joints 13 are riveted to the corresponding frame tubes at preset holes to form the four-sided frame of the base frame.

[0037] Preferably, a reinforcing horizontal tube 38 is provided inside the frame of the base frame 3. The reinforcing horizontal tube 38 is fitted onto the base frame 3 through horizontal sleeves 36 at both ends, and is fixed by rivets inserted into preset holes to achieve assembly of the reinforcing horizontal tube 38 and the base frame 3. Multiple sets of reinforcing horizontal tubes 38 can be arranged at intervals to enhance the structural strength and support of the base frame 3.

[0038] A U-shaped fixing plate 32 is installed on the long base tube 37 of the base frame 3 by rivets 4, which is adapted to the position characteristics of the side frame 1 distributed between the two fixing frames 2. The U-shaped fixing plate 32 is distributed near both ends of the long base tube 37.

[0039] The U-shaped fixing plate 32 has an upward-facing slot. The bent structure formed by the double-bend joints 23 at the two bottom corners of the fixing frame 2 and the fixing side tube 24 is inserted into the U-shaped fixing plate 32. Then, rivets 4 are inserted through the pre-reserved mounting holes of the U-shaped fixing plate 32 and the fixing side tube 24 to realize the assembly connection between the fixing frame 2 and the base frame 3.

[0040] The U-shaped fixing plate 32 has an open slot structure and forms a hinged connection with the fixing side tube 24, so that the fixing frame 2 can be flipped relative to the base frame 3 to meet the needs of folding or opening.

[0041] It should be noted that the rivet mounting holes on the U-shaped fixing plate 32 are reserved near the top of the U-shaped fixing plate 32. This design raises the fixing frame 2 when folded and closed, thereby meeting the folding and closing requirements with the fixing frame 2 on top and the side frame 1 on the bottom.

[0042] In addition, positioning posts 33 are installed on the short base tube 34 of the base frame 3, and positioning pads 35 are installed on the long base tube 37 of the base frame 3. The positioning posts 33 can be matched with the positioning holes on the trolley for quick installation; the positioning pads 35 can be matched with the buckles 5 on the trolley for easy detachable installation.

[0043] In summary, the specific structural assembly operations for the foldable storage bag frame disclosed in this embodiment are as follows: 1) For base frame 3: 1.1 Insert the horizontal tube sleeve 36 into the long base tube 37, move it to the mounting hole, and then insert the rivet 4 to press and fix it. 1.2 Insert the positioning pad 35 into the long base tube 37, move it to the mounting hole, and then insert the rivet 4 to press and fix it. 1.3 After inserting one end of the single-bend joint 13 and the U-shaped fixing plate 32 into the long base tube 37, rivets 4 are inserted into the mounting holes for pressing and fixing. 1.4 After inserting the positioning pin 33 into the mounting hole of the short base tube 34, insert the rivet 4 and press it in place; 1.5 The two ends of the reinforced horizontal tube 38 are installed into the horizontal tube sleeve 36, and the two ends of the short base tube 34 are inserted into the other end of the single bend joint 13. The rivets 4 are inserted into the mounting holes of the tube and the joint and then pressed and riveted to fix them. At this point, the base frame is assembled.

[0044] 2) For mounting bracket 2: 2.1 Insert the limiting block 25 into the fixing tube 24, move it to the mounting hole, and then insert the rivet 4 to press and fix it; 2.2 After the fixed horizontal tube 22 and the fixed side tube 24 are connected into a frame using double-bend joints 23, the double-bend joints 23 at the two bottom corners of the fixed frame 2 are inserted into the U-shaped fixed plate 32. The rivets 4 are then inserted into the mounting holes of the fixed horizontal tube and the joint, as well as into the mounting holes of the fixed side tube, the joint and the U-shaped fixed plate 32, and then pressed and riveted to fix them. At this point, the mounting bracket 2 is assembled onto the base frame 3.

[0045] 3) For side frame 1: 3.1 Insert the positioning ring 15 and the side lock 14 into the short side frame tube 16, move them to the mounting hole, and then insert the rivet 4 into the positioning ring 15 to press and fix it. 3.2 After the long side scaffold tube 12 and the short side scaffold tube 16 are connected to form a frame using a single bend joint 13, the rivets 4 are inserted into the mounting holes of the scaffold tube and the joint and then pressed and riveted to fix them. 3.3 Insert the side-opening frame hinge 17 into the long side frame tube 12 at the bottom edge. After the side-opening frame hinge 17 moves to the mounting hole of the long bottom frame tube 37 of the bottom frame 3, insert the rivet 4 to fix it.

[0046] At this point, side frame 1 is assembled onto base frame 3.

[0047] After the above assembly operations, the foldable storage bag frame of this embodiment is obtained, such as... Figure 8 As shown, when folded, the side frame 1 is located below the fixed frame 2, the two sets of side frames are staggered and folded up and down, and the two sets of fixed frames 2 are laid flat and folded on the two sets of side frames. When needed, from the closed state to the open state, flip the fixed frame outward 2 to 90°, then flip the side frame outward 1 to 90° and push it against the limit block 25, then rotate the side lock 14 outward to lock it in the short side frame tube 16 and fix it in place. The storage bag frame is fixed in a stable open state by using a buckle.

[0048] Similarly, when moving from the open state to the closed state, rotate the side lock 14 inward to release the locking effect of the short side frame tube 16, then flip the side frame 1 inward to balance with the base frame 3, and finally flip the fixed frame 2 inward to balance with the base frame 3, thus closing the storage bag frame in a hinged manner.

[0049] Example 2 This embodiment discloses a foldable storage bag, based on the foldable storage bag frame disclosed in Embodiment 1, such as... Figure 1 and Figure 2 As shown, a side cloth 11 is installed on the side frame 1 of the storage bag frame, a fixing cloth 21 is installed on the fixing frame 2, and a bottom cloth 31 is installed on the bottom frame 3.

[0050] For the side fabric 11, the fixing fabric 21, and the bottom fabric 31, clearance holes are reserved at the side positions to avoid the side lock 14, the limit block 15, and the side opening frame hinge 17, etc., and Velcro is installed at the remaining positions. After tearing off the installation Velcro of the side fabric 11, the fixing fabric 21, and the bottom fabric 31, and covering the corresponding side frame, fixing frame, and bottom frame respectively, they can be attached and fixed, which can facilitate the installation or removal of the side fabric 11, the fixing fabric 21, and the bottom fabric 31.

[0051] like Figure 9 The diagram shown illustrates the usage flow of the foldable storage bag from its folded to its open state. The operating principle is the same as that of the foldable storage bag frame in Embodiment 1. Step 1: Lay the storage bag flat with the opening facing upwards; Step 2: Flip the fixing bracket outwards 2 to 90 degrees; Step 3: Flip the side frame 1 outward to 90° and push it against the limit block 25. At this time, both the fixed frame 2 and the side frame 1 are perpendicular to the base frame 3. Step 4: Rotate the side lock 14 outwards and secure it in the short side frame tube 16. All four side locks 14 are now locked in place. Step 5: Open and use the storage bag.

[0052] To move the foldable storage bag from the open to the closed state, the operation is reversed: rotate the side lock 14 inward to release the locking effect of the short side frame tube 16, then fold the side frame 1 inward to balance with the base frame 3, and finally fold the fixed frame 2 inward to balance with the base frame 3, thus closing the storage bag in a hinged manner.

[0053] Example 3 This embodiment discloses a handcart, such as Figure 10 As shown, the foldable storage bag of Embodiment 2 is placed on the cart rack.

[0054] Based on the positioning post 33 set on the foldable storage bag base frame 3, positioning holes adapted to the positioning post 33 are opened on the vehicle frame to facilitate the quick positioning and placement of the storage bag.

[0055] At the same time, such as Figure 11 and Figure 12 As shown, buckles 5 that are adapted to positioning pads 35 are also installed on the cart frame. Buckles 5 are distributed on both the left and right sides. When the buckles 5 are closed, they form locking and fixing points with the positioning pads, so that the storage bags can be detachably installed on the trolley so that the storage bags can be removed and used separately.

[0056] In summary, the foldable storage bag frame, the storage bag containing the foldable storage bag frame, and the trolley using the storage bag disclosed in this utility model have the advantages of convenient operation and use while maintaining the good structural stability of the storage bag. At the same time, the foldable performance effectively reduces the space occupied by the storage bag during storage or transportation, and has good market prospects.

[0057] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
