[0031] This specific embodiment is a multifunctional plastic bag, the structural diagram of which is shown below. Figures 1-12 As shown.

[0032] Example 1

[0033] like Figures 1-6 The multifunctional plastic bag shown includes a box body 1 and a protective cap 11. The top of the box body 1 is open. A movable box 2 is hinged to the top surface of the box body 1. The movable box 2 has a semi-circular structure. A baffle 4 is hinged to the front side wall of the movable box 2. Two shoulder straps 7 are movably connected to the rear side wall of the box body 1. Placement bags 8 are detachably connected to the left and right side walls of the box body 1 near the bottom. The inner cavity of the box body 1 is provided with a layered assembly. The protective cap 11 is snapped onto the side wall of the box body 1.

[0034] The plastic bags in this solution can be used for storing books, food delivery, and other applications.

[0035] like Figure 2 and Figure 3 As shown, the front of the baffle 4 near the top is fixedly connected to the side wall of the movable box 2 with a first Velcro 5. The front of the movable box 2 is fixedly connected to the side wall of the box body 1 near the top with a second Velcro 6.

[0036] The first hook and loop fastener 5 and the second hook and loop fastener 6 are respectively divided into hook side and rough side, so that the hook and loop fasteners on both sides can be attached to each other. In addition, the first hook and loop fastener 5 and the second hook and loop fastener 6 will not be affected by rainwater causing a decrease in adhesion, and have good stability, effectively ensuring the stability between the baffle 4 and the movable box 2, and the stability between the box body 1 and the movable box 2. Other connection structures can also be replaced according to actual needs to achieve fixation.

[0037] like Figure 1As shown, the top surface of the movable box 2 has a concave structure, and a handle 3 is fixedly connected to the side wall of the movable box 2 at the concave part. The handle 3 is provided to facilitate the movement of the box body 1 by hand, making it more flexible.

[0038] like Figure 2 and Figure 6 As shown, the storage bag 8 is fixedly connected to a T-shaped block 9, and multiple connecting blocks are fixedly connected to the left and right side walls of the box body 1. The top surface of each connecting block has a T-shaped groove 10, which fits into the T-shaped block 9. The interlocking method between the T-shaped block 9 and the T-shaped groove 10 allows for the disassembly of the storage bag 8, and the height of the storage bag 8 can be adjusted by using multiple connecting blocks to accommodate different items.

[0039] like Figure 1 and Figure 5 As shown, two restraint straps 12 are fixedly connected to the side wall of the protective cap 11, and a diamond ring 13 is fixedly connected to the other end of the restraint strap 12. The left and right side walls of the box body 1 are respectively fixedly connected with retaining rings 14, and the diamond ring 13 and retaining ring 14 are compatible.

[0040] In rainy weather, the protective helmet 11 can be removed directly for rain protection. The helmet 11 has a large brim diameter, so rainwater will not directly hit the user's face and cause vision interference compared to wearing a raincoat with a rain hood. This ensures the user's vision and facilitates cycling safety.

[0041] like Figure 4 As shown, the layered assembly includes corrugated plates 15 fixedly connected to the inner walls of the left and right sides of the housing 1, and multiple shelves 16 are arranged between the two corrugated plates 15. Each recessed position on the corrugated plate 15 represents a height. The shelf 16 can be placed in the recessed position of the corrugated plate 15 as needed. When placing or removing the shelf 16, it is necessary to remove it with one end tilted to avoid jamming.

[0042] In this embodiment, when in use, the user can adjust the length of the shoulder strap 7 according to their needs. When placing items, the items are first placed at the bottom of the box 1. After the bottom is placed, the height of the shelf 16 is adjusted according to the height of the items so that the items can be stacked. This can effectively increase the space of the box 1. Smaller items can be placed in the movable box 2 to achieve the purpose of partitioned placement. The items are then fixed by the first Velcro 5 and the second Velcro 6.

[0043] Example 2

[0044] The similarities between this embodiment and Embodiment 1 will not be repeated here. The differences between this embodiment and Embodiment 1 are as follows: Figure 7As shown, a movable box 2 is hinged to the top surface of the box 1, and a first Velcro 5 is fixedly installed on the bottom front of the movable box 2. A second Velcro 6 is fixedly installed on the front of the box 1. When the protective cap 11 is snapped onto the box 1, there is a gap between the second Velcro 6 and the protective cap 11. This arrangement will not affect the adhesion and fixation of the first Velcro 5 and the second Velcro 6. In this embodiment, the movable box 2 is designed to open from the front.

[0045] Example 3

[0046] The similarities between this embodiment and Embodiment 1 will not be repeated here. The differences between this embodiment and Embodiment 1 are as follows: Figure 8-9 As shown, the sides of the housing 1 are no longer corrugated plates 15, and the shelves 16 are no longer provided. The sides of the housing 1 are provided with mounting slots 17, which are composed of multiple narrow slots 171 and wide slots 172 connected alternately.

[0047] The housing 1 is provided with multiple horizontal plates 181, and deformable mounting blocks 180 are provided on both sides of the horizontal plates 181. The shape of the mounting blocks 180 matches the wide slot 172, so the mounting blocks 180 can deform under force and then enter the wide slot 172 through the narrow slot 171. Therefore, the horizontal plates 181 can be installed in different positions of the housing 1 by mounting them in different wide slots 172. Thus, the horizontal plates 181 are mounted in the housing 1 and divide the housing 1 into multiple spaces. Moreover, the number and position of the horizontal plates 181 can be increased or decreased according to the actual space requirements.

[0048] Example 4

[0049] The similarities between this embodiment and Embodiment 3 will not be repeated here. The differences between this embodiment and Embodiment 3 are as follows: Figure 10 As shown, the box body 1 is provided with a vertical plate 182, and deformable mounting blocks 180 are provided on both sides of the vertical plate 182. The shape of the mounting block 180 matches the wide slot 172, so the mounting block 180 can deform under force and then enter the wide slot 172 through the narrow slot 171; thereby realizing the mounting of the vertical plate 182 in the box body 1 and dividing the box body 1 into front and rear spaces.

[0050] Example 5

[0051] The similarities between this embodiment and Embodiment 3 will not be repeated here. The differences between this embodiment and Embodiment 3 are as follows: Figure 11-12 As shown, the housing 1 is provided with an L-shaped plate 183, and deformable mounting blocks 180 are provided on both sides of the L-shaped plate 183. Since the shape of the mounting block 180 matches the wide slot 172, the L-shaped plate 183 can be installed in different positions of the housing 1 by mounting it in different wide slots 172.

[0052] Moreover, the mounting block 180 can deform under force and then enter the wide slot 172 through the narrow slot 171; thereby realizing the L-shaped plate being mounted in the box 1 and dividing the box 1 into the front upper space and the rear lower space.

[0053] All technical features in this embodiment can be freely combined according to actual needs.

[0054] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
