Description

Technical Field

[0001] This utility model relates to a screw reinforcement structure for an adhesive trolley case. Background Technology

[0002] With the increasing demand for modern travel, rolling suitcases, as a convenient travel tool, have become an essential item for people's daily travel. Rolling suitcases not only need to have high load-bearing capacity, but also need to be shock-resistant, pressure-resistant, and stable for long-term use. Therefore, the design and manufacturing quality of rolling suitcases have become key factors affecting their performance and market competitiveness. In particular, the frame, as the supporting structure of the rolling suitcase, bears the main load of the suitcase and is subjected to various external impacts and pressures.

[0003] Most suitcases on the market currently use traditional assembly methods, fixing the frame to other components with screws, rivets, etc. However, existing technology has the following major drawbacks:

[0004] Poor stability of locking structure: Traditional locking structures often rely on screws or external clips for connection. Such structures are prone to loosening or damage due to frequent vibration or external force during long-term use, affecting the stability of the frame, causing deformation of the box, and affecting its service life.

[0005] Low assembly efficiency: Traditional suitcase assembly methods typically require multiple parts and tools, and the assembly and installation of each part is quite complex. This cumbersome assembly method not only increases production costs but also extends the production cycle and affects product delivery time.

[0006] Insufficient sealing and shock resistance: Most existing locking structures cannot guarantee sufficient sealing and shock resistance, especially at the connection between the box frame and other components, which are easily subjected to external pressure and impact, resulting in damage to the items inside the box, or cracks and deformation of the box during transportation.

[0007] Poor material and process adaptability: Existing locking structure designs are poorly adaptable to production processes. Many designs can only adapt to a single material or a single process, and cannot effectively meet the needs of different materials and different production processes, thus limiting product diversification and market adaptability. Utility Model Content

[0008] The purpose of this utility model is to provide a screw reinforcement structure for an adhesive trolley case. By reasonably combining the design of adhesive and screw reinforcement, the problem of structural instability and poor impact resistance that may exist in traditional trolley cases during long-term use is solved, thereby improving the overall performance and service life of the trolley case.

[0009] The technical solution adopted by this utility model to solve its technical problem is:

[0010] A screw-reinforced structure for an adhesive trolley case includes a case frame body and side panels on both sides of the case frame body that are adhesively connected to the case frame body. The side of the case frame body has a tapered connecting edge, and the side panel is fitted onto the tapered connecting edge and fits into the tapered connecting edge. The connecting edge has a plurality of plug holes for injecting glue to form a plug structure. The periphery of the plug holes has screw-reinforced holes for screws to be screwed in from the inside out to abut against the side panel.

[0011] Preferably, there is one or more screw reinforcement holes, and at least two are provided at each edge of the connection.

[0012] Preferably, the screw screwed into the screw reinforcement hole forms a screw-in fixation or a screw-in through-hole at the opposite side of the box plate.

[0013] Preferably, the plug hole is a strip-shaped, elliptical, polygonal, or circular hole structure.

[0014] Preferably, the glue injection direction of the plug hole is from the inside out to form the plug structure.

[0015] Preferably, the structural direction of the screw reinforcement hole is perpendicular to the glue injection direction of the plug hole, and the thread length of the screw reinforcement hole is adapted to the depth of the plug hole.

[0016] Preferably, the adhesive bonding area between the side panel and the frame body is evenly distributed along the entire length of the bonding edge, and is fitted with multiple adhesive plug holes and screw reinforcement holes.

[0017] The beneficial effects of this utility model are:

[0018] Improving the structural strength and stability of suitcases: Traditional adhesive connections can easily loosen or detach after prolonged use or impact. By combining adhesive and screw reinforcement, the overall stability and impact resistance of the suitcase can be effectively improved, thus extending its service life. This solution involves designing adhesive plug holes on the connection edges of the suitcase frame and adding screw reinforcement holes around these holes. This combination of adhesive injection and screw reinforcement ensures a more secure connection between the side panels and the frame, preventing loosening at the connection points due to prolonged use or excessive loads.

[0019] The tapered design of the connecting edges and their adaptation to the side panels ensures precise and tight connections, reducing errors during installation and thus improving production efficiency and product quality. The design of the glue plug holes and screw reinforcement holes makes the assembly process of the suitcase simpler and more efficient. This structure allows for faster assembly of the suitcase and provides a more reliable fixation effect through two connection methods (glue and screws), avoiding the instability that may result from a single connection method. By rationally designing the number and position of the glue plug holes and screw reinforcement holes, adjustments can be made according to the size and usage requirements of the suitcase, ensuring that different models of suitcases have sufficient load-bearing capacity under different load conditions.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Example

[0025] See Figure 1-2 As shown, a screw reinforcement structure for an adhesive trolley case includes a case frame body 1 and side case panels 2 disposed on both sides of the case frame body 1 and adhesively connected to the case frame body 1. The side of the case frame body 1 is provided with a tapered connecting edge 11. The side case panel 2 is fitted onto the tapered connecting edge 11 and is adapted to the tapered connecting edge 11. The connecting edge 11 is provided with a plurality of glue plug holes 12 for injecting glue to form a glue plug structure. The periphery of the glue plug hole 12 is provided with screw reinforcement holes 13 for screws to be screwed in from the inside to the outside to abut against the side case panel 2.

[0026] By combining adhesive bonding and screw reinforcement, the connection stability between the main frame 1 and the side panel 2 can be effectively improved. When subjected to external impacts or weight, the adhesive and screws work together to enhance the impact resistance of the case structure and prevent the suitcase from loosening or deforming during long-term use.

[0027] The tapered design of the connecting edge 11, which fits perfectly with the side panel 2, not only makes the connection more precise but also reduces errors in production, making the assembly process simpler and more efficient. Furthermore, the well-placed plug holes 12 and screw reinforcement holes 13 allow for quick installation while ensuring a strong connection, thereby improving production efficiency.

[0028] This design, by incorporating multiple plug holes 12 and screw reinforcement holes 13, allows for adjustment of reinforcement points according to different sizes and load requirements, ensuring the stability and load-bearing capacity of the suitcase in various usage environments. This design is particularly suitable for suitcases requiring high load-bearing capacity and frequent handling, adapting to different usage scenarios while maintaining excellent structural performance.

[0029] The screw reinforcement hole 13 is provided in more than one way, and at least two are provided at each edge of the connecting edge 11. The screw screw screwed into the screw reinforcement hole 13 forms a screw-in fixation or a screw-in through-hole at the opposite side box plate 2.

[0030] Providing at least two screw reinforcement holes 13 along each side ensures a more uniform and stable connection. The distribution of multiple screws allows each screw to bear a relatively balanced load, avoiding localized stress concentration, thereby enhancing the fixing strength between the side panel 2 and the box frame body 1, and ensuring the structural stability of the suitcase under high loads or impacts.

[0031] By providing multiple screw reinforcement holes 13 on the connecting edge 11, the screws can be screwed in through or screwed in for fixation, further enhancing the fixing effect on the side panel 2. This design can effectively reduce the risk of loosening when the case is subjected to external impacts, increase the resistance of the suitcase to vibration and impact during use, and extend the service life of the product.

[0032] The placement of multiple screw reinforcement holes 13 is flexible and can be adjusted according to different models, sizes, or load-bearing requirements. During production, the number of screw reinforcement holes 13 can be increased or decreased as needed, thus better adapting to the demands of different markets and usage environments. Furthermore, the multiple screw hole design provides more adjustment space for production, facilitating quality control and consistency during mass production.

[0033] The plug hole 12 is a strip-shaped, elliptical, polygonal, or circular hole structure. The glue injection direction of the plug hole 12 is from the inside to the outside to form the plug structure. The structure direction of the screw reinforcement hole 13 is perpendicular to the glue injection direction of the plug hole 12, and the thread length of the screw reinforcement hole 13 is adapted to the depth of the plug hole 12. The adhesive bonding area between the side panel 2 and the box frame body 1 is evenly distributed along the entire length of the connecting edge 11 and is matched with the screw reinforcement hole 13 through multiple plug holes 12.

[0034] Because the plug hole 12 and the screw reinforcement hole 13 are structurally optimized, with the screw reinforcement hole 13 perpendicular to the glue injection direction of the plug hole 12, the connection between the plug and the screw is ensured to be tighter, avoiding mutual interference between the two connection methods. The plug provides strong adhesive force, while the screw reinforcement strengthens the mechanical fixing force. This dual protection significantly improves the stability and tensile strength of the connection, ensuring the reliability of the suitcase under external impact and long-term use.

[0035] The adhesive bonding area is evenly distributed along the entire length of the bonding edge 11, which allows the load to be evenly distributed across the entire bonding surface, reducing stress concentration and preventing localized structural deformation or damage. The combination of multiple adhesive plug holes 12 and screw reinforcement holes 13 disperses pressure, providing more balanced support and enhancing the overall durability and pressure resistance of the suitcase.

[0036] This design allows for more precise control over the depth of the plug hole 12 and the thread length of the screw reinforcement hole 13 during production, ensuring a good fit between the two and thus improving assembly efficiency and accuracy. The combination of multiple plug holes 12 and screw reinforcement holes 13 reduces assembly errors, improves overall assembly quality, further increases production efficiency, and reduces process complexity. Simultaneously, the optimized design also enhances consistency and quality stability in mass production.

[0037] The above embodiments of this utility model are not intended to limit the scope of protection of this utility model. The implementation of this utility model is not limited thereto. All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
