[0026] In the description of this invention, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. The various embodiments of this invention are described in detail below with reference to the accompanying drawings.

[0027] Example 1:

[0028] Please see Figures 1 to 5The present invention provides a preferred technical solution: a draggable schoolbag, comprising: a bag body 6, and a mesh handle 16 connected to the top of the bag body 6. The mesh handle 16 has a grid structure, and by adjusting the different positions of the hand gripping the grid structure, the schoolbag can be dragged more conveniently and comfortably when the human body is upright; and an assembly structure set at the bottom of the bag body 6 for assembling and connecting a lightweight moving bracket; under the action of the mesh handle 16 and the lightweight moving bracket, the bag body 6 can be dragged on the ground.

[0029] In this embodiment, such as Figure 1 and 3 As shown, in use, the bag body can be connected and supported on the lightweight moving bracket by the assembly structure set at the bottom of the bag body 6. At this time, the bag body can be moved by the moving wheel assembly at the bottom of the lightweight moving bracket. The lightweight moving bracket is made of lightweight material, and after the plate assembly and the bag body are combined, it does not affect the use of the bag body itself.

[0030] The combination of a lightweight mobile support and the bag body is especially suitable for primary school students carrying heavy loads to and from school. It can support the bottom of the existing schoolbag, giving the schoolbag the function of a mobile wheel. Through the rolling of the mobile wheel, its labor-saving and efficient operation greatly facilitates the students' carrying process.

[0031] And as Figure 1 As shown, the mesh handle 16 is designed so that children of different heights can choose the position to pull. The flexible handle, combined with the lightweight mobile support and the bag body 6, solves the problem of backpack weight and also solves the drawbacks of wheeled backpacks, which has great practical significance.

[0032] Furthermore, when the mesh handle 16 is naturally stretched, the distance between it and the top of the backpack is greater than 10 centimeters, and the bottom of the mesh handle 16 is provided with a buckle 17 and a slot 18 provided at the bottom of the bag body 6, the buckle 17 can engage with the slot 18.

[0033] The design of the buckle 17 and the slot 18 facilitates the locking of the end of the mesh handle 16, which can be used as a strap or net to tie and carry accessories such as umbrellas and sleeping mats.

[0034] Furthermore, the lattice structure is a ladder-like structure, preferably designed to grow in stages.

[0035] Furthermore, the assembly structure includes a fixing strap 7 disposed on the bag body 6, which can be used to fix the lightweight mobile support to the bottom of the bag.

[0036] like Figure 3As shown, in one embodiment of the assembly structure, the lightweight mobile support is mainly combined with the backpack. A fixing strap 7, preferably two, is provided at the bottom of the backpack body 6 for inserting the plate body 3. In the embodiment of the soft-bottom backpack, the soft bottom is transformed into a hard bottom, which facilitates the subsequent installation of the mobile wheel assembly.

[0037] Example 2:

[0038] A lightweight mobile support can be applied to the aforementioned draggable backpack, including: a plate 3, and a movable wheel assembly detachably mounted on the plate 3; the plate 3 can be inserted between the fixing straps 7, the length and width of the plate 3 are not greater than the length and width of the bottom of the corresponding backpack, and the plate is made of lightweight material. By setting the size and material of the plate 3, the overall safety and lightweight of the backpack are optimized to a certain extent.

[0039] As one implementation of a lightweight mobile support, the plate 3 is inserted between the fixing straps 7, which can realize the function of changing the soft bottom of the backpack to a hard bottom. With the mobile wheel assembly, it can be assembled into a simplified mobile backpack.

[0040] Furthermore, the movable wheel assembly includes waterproof feet 11 located at the four corners of the plate 3, and the waterproof feet 11 have threaded holes inside for mounting the wheel body 5.

[0041] When the wheel 5 is installed on the waterproof foot 11, it can be used to form a mobile support frame, making it easy to move the backpack with minimal effort. When the wheel 5 is not installed, the waterproof foot 11 forms the four legs of the plate 3, which are used to suspend and support the bottom of the bag, preventing the bottom of the bag from getting wet or dusty.

[0042] Another implementation of the lightweight mobile support also includes a support plate 1 and a locking post 10 disposed on the lower surface of the support plate 1; a locking groove 9 is also provided in the middle of the plate body 3, the locking groove 9 corresponding to the locking post 10. When the support plate 1 is inside the bottom of the backpack and the plate body 3 is outside the bottom of the backpack, the soft bottom of the backpack can be clamped in the middle and locked, so that the plate body 3 can be fixed to the bottom of the backpack. As another combination of the support plate 1 and the plate body 3, such as Figure 2 As shown, at this time, the card plate 10 engages with the card slot 9 where the plate body 3 is located, and the limiting sleeve 8 is attached to the lower surface of the plate body 3. The limiting sleeve 8 is made of elastic rubber material.

[0043] The support plate 1 has mounting holes 2, and each mounting hole corresponds to a threaded hole inside the waterproof foot.

[0044] In this embodiment, when the support plate 1 is assembled on the soft bag body 6, the corresponding wheels can be assembled under the action of the mounting holes 2, thus transforming the existing soft backpack into a hard-bottomed movable backpack.

[0045] Example 3:

[0046] As another embodiment of the present invention, the plate 3 is also provided with a backrest 12, the backrest 12 is provided with a fixing hole 13, and the backrest 12 is provided with a concave surface in the middle so as to better fit the back when carrying it, and at the same time effectively reduce the impact force when the rigid lightweight plate accidentally hits the body.

[0047] One end of the fixing strap 7 is detachably connected to the bag body 6 and is used to pass through the fixing hole 13 where the backing plate 12 is located.

[0048] like Figure 4 As shown, a backrest 12 is also provided on the side where the support plate 1 is located. The shape of the backrest 12 fits the student's spine. Under the structural action of the backrest 12 and the support plate 1, on the one hand, it can improve the support force when the student carries the schoolbag, and on the other hand, it can reduce the risk of the student's spine deformation and bending.

[0049] Example 4:

[0050] In another embodiment of the present invention, a backrest 12 is provided on the lightweight mobile support, and a backrest fixing sleeve 14 is also provided on the bag body 6; a pocket cavity is formed between the fixing sleeve and the back of the bag body, which fixes the backrest to the back of the backpack, thereby improving the carrying comfort while ensuring the support strength.

[0051] In this embodiment, the protrusion of the backrest 12 is first inserted into the plug sleeve 14. At this time, the limiting straps 15 on both sides of the bag body 6 are inserted through the inside of the backrest 12, through the through groove 13, and extended to the bottom of the support plate 1 and connected to the front part of the bag body 6. The connection method can be a buckle or Velcro, which realizes the quick assembly of the lightweight mobile bracket and the backpack.

[0052] One construction method can be applied to the aforementioned draggable backpack:

[0053] A mesh handle 16 with a lattice structure is positioned on the top of the package 6 to form a flexible handle, wherein the mesh handle 16 has a ladder-like structure;

[0054] The two open fixing straps 7 are positioned at the bottom of the bag body 6 to form a connecting layer structure, which facilitates the assembly of the moving bracket.
