Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, specifically a bicycle wheel fixing box. Background Technology

[0002] In the production and transportation of bicycles, wheels are typically sealed in enclosed cardboard boxes. However, existing sealing methods have the following problems:

[0003] 1. The wheels lack effective positioning inside the box, making them prone to shaking during transportation, which can lead to deformation of the packaging box or scratches and damage to the surface of the wheels.

[0004] 2. The wheel axle has a small contact area with the inner wall of the cardboard box. Under transportation vibration or stacking pressure, the wheel axle is easy to puncture the packaging box, reducing the protective effect.

[0005] 3. Currently, inflatable bags, foam, or newspapers are commonly used as fillers to secure wheels and absorb impacts. However, the specifications of these fillers are not uniform, and the quality of filling depends on the experience of workers, resulting in low efficiency, high cost, and inconsistent protective effects.

[0006] While existing solutions can partially alleviate the aforementioned problems, they still suffer from drawbacks such as uncontrollable manual operation, material waste, and low standardization. Therefore, there is an urgent need for a packaging solution that is structurally stable, highly standardized, and can effectively protect bicycle wheels to improve transportation safety and reduce packaging costs. Utility Model Content

[0007] To address the technical problems in the background art, this utility model discloses a bicycle wheel fixing box.

[0008] This utility model provides a bicycle wheel fixing box, including a box body, which is encapsulated in a packaging box; the bicycle wheel locking limit is located in the box body;

[0009] The box is open at one end, aligning with the wheel axis.

[0010] The opening end of the box extends inward to a limiting part;

[0011] The wheel is engaged between the limiting part and the bottom of the box;

[0012] The box is made of a flat piece of cardboard, which is formed by bending and snapping together.

[0013] Furthermore, the box body has an open end face that is square.

[0014] Furthermore, inclined blocking parts are also provided at the four corners of the box.

[0015] The blocking part extends in the thickness direction of the box body;

[0016] The outer radial side of the wheel abuts against the inner side of the blocking part.

[0017] Furthermore, the box body includes a box bottom; the box bottom extends vertically to form two symmetrically arranged first sides and two symmetrically arranged second sides; the open end of the first side extends inward to form a limiting part that is bent four times and forms a rectangular tube shape; the last bent part of the limiting part is fixedly connected to the inner side of the first side by glue.

[0018] Furthermore, the opening end of the second side extends inward to form a connecting surface.

[0019] Furthermore, a groove is provided on the connecting surface; the groove is in the shape of an isosceles trapezoid, with the lower base of the isosceles trapezoid being the opening end of the groove.

[0020] Furthermore, the two ends of the first side are bent to extend out blocking parts; the second side is provided with an inwardly protruding snap-fit ​​plate; the end of the blocking part snaps into the snap-fit ​​plate.

[0021] Furthermore, a slot is provided at the connection between the first side and the bottom of the box; the two ends of the connecting surface are led out in sequence by bending twice; the connecting part fits against the outer side of the first side; the slot is inserted into the slot from the outside to the inside.

[0022] Furthermore, the snap-fit ​​part is designed as two folded layers; when the snap-fit ​​part is snapped into the slot, one layer of the snap-fit ​​part unfolds towards the opening end of the box to form an acute angle.

[0023] The beneficial effects of this utility model are:

[0024] 1. The wheel is axially locked and fixed by the limiting part designed inside the box and the bottom, which effectively limits the radial and axial displacement during transportation, avoids the deformation of the packaging box or scratches on the surface caused by wheel shaking, and significantly improves transportation safety.

[0025] 2. The limiting part forms a multi-point contact support with the bottom of the box, which increases the contact area between the wheel axle and the packaging box, disperses the stacking pressure and vibration impact, prevents the wheel axle from being concentrated and puncturing the cardboard box, and extends the service life of the packaging.

[0026] 3. The box body is formed by bending and snapping together a single sheet of hardboard paper, with an integrated structure and no need for additional fillers. This simplifies the production process, avoids the randomness of manual filling, achieves uniform packaging specifications, and reduces material waste and labor costs.

[0027] 4. It abandons traditional non-degradable fillers such as foam and air bags, and can achieve high protection with only cardboard. The material is recyclable and inexpensive, which is in line with the trend of green packaging.

[0039] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0040] This utility model discloses a bicycle wheel fixing box, including a box body 1, which is encapsulated inside a packaging box, and the outer side of the box body 1 is attached to the inner side of the packaging box. The bicycle wheel is snapped into the box body 1 to achieve limiting and fixing.

[0041] The specific structure of box 1 is as follows:

[0042] like Figure 1-3 As shown, the box body 1 includes a square flat box bottom 11. Two of the opposite outer sides of the box bottom 11 extend outwards perpendicularly to the first side 12, and the other two outer sides extend outwards perpendicularly to the second side 13, so that the box body 1 is in the shape of an opening at one end, and the opening end is located on the axial direction of the wheel.

[0043] like Figure 4 As shown, the opening end of the first side 12 extends inward to form a limiting part 2, which is bent four times and forms a rectangular tube shape; the last bent part of the limiting part 2 is fixedly connected to the inner side of the first side 12 with glue. The limiting part 2 and the bracket of the box bottom 11 are spaced apart. One end of the wheel axle is fitted with a hub protective cover made of ABS material, and the outer side of the hub protective cover abuts against the box bottom 11; the wheel part abuts against the limiting part 2, thereby realizing the wheel installation limiting.

[0044] Both ends of the first side surface 12 extend blocking portions 3 formed by two bends; the portion of the blocking portion 3 that is bent in the first bend extends toward the limiting portion 2 and forms an acute angle with the first side surface 12; the portion that is bent in the second bend extends toward the second side surface 13 and forms an obtuse angle with the second side surface 13. The radially outer side surface of the wheel abuts against the inner side surface of the portion of the blocking portion 3 that is bent in the second bend. The blocking portions 3 are arranged symmetrically, forming a square, and are used to limit the radial movement of the wheel.

[0045] The second side 13 has two symmetrical, back-to-back U-shaped slots 20; the part inside the slots 20 is a snap-fit ​​plate 16, as shown in the figure. Figure 5 As shown, the snap-fit ​​plate 16 is bent inward at an acute angle; after bending, a rectangular hole is formed at the cut groove 20. The end of the second bend of the blocking part 3 snaps into the side of the snap-fit ​​plate 16 opposite the rectangular hole and extends to the root of the snap-fit ​​plate 16. Due to the restoring stress after bending, there is pressure between the snap-fit ​​plate 16 and the blocking plate, making the position of the blocking part 3 more stable.

[0046] The opening end of the second side 13 extends inward to form a connecting surface 14, increasing the contact area between the opening end of the box body 1 and the packaging box, thus preventing the box body 1 from deforming. Since only the four corners of the box body 1 are subjected to force when sealed inside the packaging box, a slot 15 is also provided at the end of the connecting surface 14. The slot 15 and the two ends of the connecting surface 14 are spaced equally to save material and reduce costs. The slot 15 is an isosceles trapezoid, with the lower base of the trapezoid forming the opening end of the slot 15. This maximizes the area of ​​the slot 15, saving material.

[0047] The connecting surface 14 has two 90° bends at both ends, leading out the connecting part 18 and the snap-fit ​​part 19 in sequence. The connecting part 18 fits against the outer surface of the first side 12; the snap-fit ​​part 19 snaps into the slot 17 at the connection between the first side 12 and the bottom of the box 11 from the outside in, thereby fixing the second side 13. The connecting part 18 limits the outer surface of the first side 12, and the slot 17 is also used to fix the second side 13, thus making the structure of the box 1 more stable.

[0048] The snap-fit ​​part 19 is designed as a double-layer structure with a fold; the layer of the snap-fit ​​part 19 near the opening end of the box body 1 unfolds under the action of bending stress, so that the snap-fit ​​part 19 of the double-layer structure forms an acute angle. This design can improve the snap-fit ​​stability of the snap-fit ​​part 19 and make it less likely to detach from the slot 17.

[0049] Based on the above structure, it can be seen that, Figure 6 As shown, box 1 is made from a flat sheet of cardboard, which is formed by bending and snapping. This design allows box 1 to unfold into a flat, flat shape before packaging and transportation, reducing the space occupied during transport, increasing the cargo capacity per shipment, and thus lowering transportation costs.

[0050] The first side 12 is also provided with two symmetrically arranged through holes 21, into which fingers can be inserted to facilitate handling.

[0051] Before assembling the box body 1, place the wheels at the bottom 11 of the box, and then bend the first side 12 and the second side 13.

[0052] Compared to existing technologies, the advantages of this embodiment are: 1. By using the limiting part 2 designed inside the box body 1 in conjunction with the bottom, the wheel is axially engaged and fixed, effectively limiting radial and axial displacement during transportation, avoiding deformation or surface scratches caused by wheel shaking, and significantly improving transportation safety. 2. The limiting part 2 and the bottom of the box body 1 form multi-point contact support, increasing the contact area between the wheel axle and the packaging box, dispersing stacking pressure and vibration impact, preventing the wheel axle from being punctured by concentrated force, and extending the service life of the packaging. 3. The box body 1 is formed by bending and snapping together a single sheet of hardboard paper, with an integrated structure and no need for additional fillers. This simplifies the production process, avoids the randomness of manual filling, achieves uniform packaging specifications, and reduces material waste and labor costs. 4. It abandons traditional non-degradable fillers such as foam and air bags, and only hardboard paper can achieve high protection. The material is recyclable and inexpensive, which is in line with the trend of green packaging. 5. During packaging, first secure the wheel to box 1, then seal box 1 inside the packaging box. This not only makes the wheel more stable but also provides double protection. 6. The wheel can be clearly seen without removing the fixing box during display; moreover, the fixing box provides stable support for the wheel during display, making its position more stable and less prone to bumps or scratches.

[0053] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
