Description

Technical Field

[0001] This utility model relates to the field of luggage technology, specifically to a luggage frame side mechanism that facilitates assembly. Background Technology

[0002] When people go out to work, visit relatives, study, or travel, they need to carry the items they need. Suitcases are essential tools for carrying these items, and suitcases with pull handles and wheels make it easier to carry luggage without having to carry it on your back. Therefore, pull handle suitcases are popular.

[0003] For example, Chinese patent application CN221813372U discloses a zipper structure and a case, including two zipper bodies. Each zipper body comprises a zipper fabric and a rib. One end of the zipper fabric is provided with a first zipper tooth, and the other end is used to connect to the inner lining of the case. The first zipper tooth engages with the first zipper tooth of the other zipper body. The rib is connected to the zipper fabric, and the zipper body is fixed to the case by fixing the rib to the case. The zipper body is fixed to the case by fixing it to the case. No manual high-speed sewing is required during the fixing process, thus reducing labor costs. Furthermore, the rib can be fixed by assembly, which is far less difficult than high-speed sewing, ensuring assembly quality and improving yield. At the same time, the rib assembly and fixing method can be easily automated in production.

[0004] The aforementioned technologies still have some drawbacks. For example, the closure method still relies on the meshing of zipper teeth, which are prone to failure due to friction, impact, and wear from prolonged exposure. Furthermore, although the zipper body is installed, the closure of the suitcase still requires operation of the zipper head, failing to simplify the closure process. Therefore, a convenient assembly mechanism for the suitcase frame is proposed to address these issues. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a convenient assembly mechanism for the frame of a suitcase. By setting a locking block on the upper frame and a limiting groove on the lower frame for embedded engagement, the upper and lower connecting parts are closed. Subsequently, only a combination lock component needs to be set between the upper and lower connecting parts to lock them together, without relying on the zipper on the outside of the suitcase.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a convenient assembly mechanism for a suitcase frame, comprising an upper connecting part and a lower connecting part located on the suitcase body, wherein the upper connecting part and the lower connecting part are respectively provided with mounting grooves, and the mounting grooves in the upper connecting part and the lower connecting part are respectively provided with a first engaging component and a second engaging component, and the first engaging component and the second engaging component are respectively provided with connecting components for engaging with the second zipper teeth at the end of the inner lining fabric in the upper connecting part and the lower connecting part; The first engaging component includes an upper frame that is adapted to be installed in the mounting groove of the upper connecting part, and a locking block is provided at the lower end of the upper frame along the length of the frame. The second engaging component includes a lower frame that is adapted to be installed in the mounting groove of the lower connecting part. The lower frame is provided with a limiting groove corresponding to the locking block. The locking block is adapted to the limiting groove for engaging and fitting into the limiting groove, so that the upper connecting part and the lower connecting part are closed. The cross-sections of the limiting groove and the locking block are both isosceles trapezoids that fit together, and the hypotenuses of the two trapezoids adapt to each other to form a guide structure, which makes it easy for the locking block to be quickly aligned and slide into the limiting groove. It also includes fasteners, with the first and last ends of the upper and lower frame frames respectively fixed to the mounting grooves of the upper and lower connecting parts by fasteners. The upper and lower frame frames are made of aluminum profiles.

[0007] Preferably, the outer surface of the card block is provided with a sealing strip along its circumference. The sealing strip is made of silicone or rubber, and the outer diameter of the sealing strip is larger than the inner diameter of the limiting groove, so that the sealing strip and the inner wall of the limiting groove form an interference fit.

[0008] Preferably, the top and bottom borders are integrally molded structures.

[0009] Preferably, it also includes fasteners, with the first and last ends of the upper and lower frame edges respectively fixed to the mounting grooves of the upper and lower connecting parts by fasteners.

[0010] Preferably, the fastener is a rivet, and the groove wall of the mounting groove is provided with mounting holes that are compatible with the fastener.

[0011] Preferably, the connecting component includes cavities respectively opened in the upper frame and the lower frame, and one side of the cavity has an opening communicating with the outside; It also includes a card strip, the side wall of which is provided with zipper fabric. The card strip and zipper fabric are inserted from one end of the frame to the other end along the extension direction of the cavity, so that the zipper fabric wraps around to form a loop structure and is completely embedded in the cavity. The cross-section of the card strip has a combined structure, consisting of a circular area and a rectangular area molded as one piece, and the cross-sectional shape of the card strip is adapted to the inner wall contour of the cavity and the bonding surface of the zipper fabric.

[0012] Preferably, it also includes a combination lock assembly, which is mounted on the connecting part and the lower connecting part.

[0013] Preferably, one end of the zipper fabric is fixed with a first zipper tooth, which meshes with a second zipper tooth inside the box.

[0014] This utility model provides a convenient assembly mechanism for luggage frame edges. It has the following advantages: This convenient luggage frame assembly mechanism achieves closure between the upper and lower connecting parts by setting a locking block on the upper frame and an embedded locking groove on the lower frame. A combination lock component can then be used to lock both parts securely, eliminating the need for an external zipper. This avoids the problems of exposed zipper teeth leading to wear, jamming, and large sealing gaps, as well as the risk of zipper protrusions scratching clothing. Combined with a sealing strip, it further enhances waterproof and dustproof performance, providing a better seal than existing zipper structures. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1-4As shown, this utility model provides a technical solution: a convenient assembly luggage frame mechanism, including an upper connecting part 1 and a lower connecting part 2 for connecting the luggage body 14. The upper connecting part 1 and the lower connecting part 2 are the main frame of the luggage body 14. They are rotated and opened and closed by hinges or flexible connecting strips. The inner sidewalls of the upper connecting part 1 and the lower connecting part 2 are provided with annular mounting grooves 7. The cross-sectional contour of the mounting grooves 7 is adapted to the shape of the first engaging component 3 and the second engaging component 5, and is used to accommodate and position the engaging components. The upper connecting part 1 and the lower connecting part 2 are respectively provided with mounting grooves 7. The upper connecting part 1 and the lower connecting part 2 are respectively provided with inner lining fabric 9. One end of the inner lining fabric 9 is fixed with a second zipper tooth 10. The mounting grooves 7 in the upper connecting part 1 and the lower connecting part 2 are respectively provided with the first engaging component 3 and the second engaging component 5. The first engaging component 3 and the second engaging component 5 are respectively provided with connecting components 15 that mesh with the second zipper tooth 10 at the end of the inner lining fabric 9 in the upper connecting part 1 and the lower connecting part 2. like Figure 2 As shown, it also includes a fixing member 11. The first and last ends of the upper frame 16 and the lower frame 17 are respectively fixed to the mounting grooves 7 of the upper connecting part 1 and the lower connecting part 2 by the fixing member 11. After the frame is embedded in the mounting groove 7, its first and last ends are the stress concentration points. Fixing the first and last ends by the fixing member 11 can limit the displacement of the frame and ensure that the relative position of the frame and the mounting groove 7 remains unchanged.

[0019] The upper frame 16 and lower frame 17 are made of aluminum profiles and are integrally formed structures. The high strength of the aluminum profiles enables the frame to withstand the pressure during engagement and the impact and vibration during daily use, preventing frame deformation that could lead to engagement failure. The integral forming process ensures the connection strength between the locking block 4, the limiting groove 6 and the frame, preventing the locking block 4 from falling off or the limiting groove 6 from cracking during long-term use.

[0020] like Figure 3 As shown, the first engaging component 3 includes an upper frame 16 adapted to be installed in the mounting groove 7 of the upper connecting part 1, and a locking block 4 is provided at the lower end of the upper frame 16 along the length of the frame. like Figures 3-4 As shown, the second engaging component 5 includes a lower frame 17 adapted to be installed in the mounting groove 7 of the lower connecting part 2. The lower frame 17 is provided with a limiting groove 6 corresponding to the locking block 4. The locking block 4 is adapted to the limiting groove 6 for engaging and engaging with the limiting groove 6, so that the upper connecting part 1 and the lower connecting part 2 are closed.

[0021] like Figures 3-4As shown, the cross-sections of the limiting groove 6 and the locking block 4 are both isosceles trapezoids that fit together, and their trapezoidal hypotenuses adapt to each other to form a guiding structure, facilitating the quick alignment and sliding of the locking block 4 into the limiting groove 6. Specifically, the inclination angle of the inner wall hypotenuse of the limiting groove 6 is consistent with the hypotenuse of the locking block 4, ensuring a seamless fit and greatly guaranteeing the stability between the locking block 4 and the limiting groove 6, making the locking block 4 less prone to loosening. When the housing 14 is closed, the trapezoidal hypotenuse of the locking block 4 contacts the hypotenuse of the limiting groove 6, and the inclination angle of the hypotenuse forms a natural guide. The pressure of the upper connecting part 1 is decomposed into a force along the depth direction of the limiting groove 6 through the inclined surface of the hypotenuse, guiding the locking block 4 to automatically align with the opening of the limiting groove 6 and slide smoothly in. After engagement, the lower trapezoidal base of the locking block 4 fits tightly with the lower trapezoidal base of the limiting groove 6.

[0022] In use, first, the upper frame 16 and the lower frame 17 are respectively fitted into the mounting slots 7 of the upper connecting part 1 and the lower connecting part 2, and the initial positioning is completed by the subsequent fastener 11; then, the connecting component 15 is engaged with the second zipper tooth 10 of the inner lining fabric 9 to achieve the pre-assembly of the inner lining fabric 9 and the engaging component. When it is necessary to close the box 14, align the upper connecting part 1 and the lower connecting part 2 around the circumferential position, press the upper connecting part 1 downwards, so that the locking block 4 of the upper frame 16 slides into the limiting groove 6 of the lower frame 17 along the guide structure of the limiting groove 6. The upper connecting part 1 and the lower connecting part 2 are closed by the tight fit between the locking block 4 and the limiting groove 6. At the same time, the matching structure between the locking block 4 and the limiting groove 6 blocks the communication between the inside and outside of the box 14, forming a seal. Conversely, by pulling the upper connecting part 1 upwards, the locking block 4 can be disengaged from the limiting groove 6, thus enabling the box 14 to open and close without relying on the zipper head, making opening and closing more convenient.

[0023] In addition, a sealing strip (not shown in the figure) can be provided on the outer surface of the locking block 4 along its circumference. The sealing strip is made of silicone or rubber, and its outer diameter is larger than the inner diameter of the limiting groove 6, so that the sealing strip and the inner wall of the limiting groove 6 form an interference fit. When the locking block 4 slides into the limiting groove 6, the sealing strip is squeezed and deformed by the inner wall of the limiting groove 6 due to the interference fit, filling the tiny gap between the locking block 4 and the limiting groove 6. The elastic recovery force of the sealing strip keeps it in close contact with the inner wall of the limiting groove 6 and the side wall of the groove of the locking block 4, forming a continuous sealing surface, preventing dust and water stains from entering the interior of the housing 14 from the locking gap, and achieving a waterproof and dustproof sealing effect. At the same time, the elastic deformation of the sealing strip can also buffer the impact force during locking, reduce the wear of the locking block 4 and the limiting groove 6, and extend the service life.

[0024] Furthermore, the fastener 11 is a rivet, and the groove wall of the mounting groove 7 is provided with mounting holes (not shown in the figure) that are adapted to the fastener 11. The fastener 11, through its adaptation and cooperation with the mounting holes, fixes the first engaging component 3 and the second engaging component 5 to the upper connecting part 1 and the lower connecting part 2, respectively.

[0025] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0026] like Figure 3-4 As shown, this utility model provides a technical solution: a convenient assembly of a suitcase frame side mechanism, wherein the connecting component 15 includes cavities 13 respectively opened in the upper frame 16 and the lower frame 17, and one side of the cavity 13 is provided with an opening communicating with the outside. like Figure 3 As shown, it also includes a card strip 18, and a zipper fabric 12 is provided on the side wall of the card strip 18. The card strip 18 and the zipper fabric 12 are inserted from one end of the frame to the other end along the extension direction of the cavity 13, so that the zipper fabric 12 surrounds to form a loop structure and is completely embedded in the cavity 13. In this embodiment, the cross-section of the clip 18 has a combined structure, integrally formed from a circular area and a rectangular area, and the cross-sectional shape of the clip 18 is adapted to the inner wall contour of the cavity 13 and the contact surface of the zipper fabric. During assembly, the zipper fabric 12 is first fixed to the side wall of the clip 18, and the clip 18 and the zipper fabric 12 are combined; then the combination is passed through from one end of the frame to the other end along the extension direction of the frame cavity 13, so that the zipper fabric 12 is exposed through the opening of the cavity 13, thus completing the pre-installation of the connecting component 15 and the frame.

[0027] like Figure 3 As shown, after the upper connecting part 1 and the lower connecting part 2 are closed, the bottom edges of the opposite surfaces of the upper connecting part 1 and the lower connecting part 2 are folded corner structures 19 facing the inside of the box 14. The folded corner structure 19 is an inverted L-shaped folded edge, which increases the strength of the opposite surfaces of the upper connecting part 1 and the lower connecting part 2 respectively.

[0028] It also includes a combination lock assembly (not shown in the figure), which is installed on the upper connecting part 1 and the lower connecting part 2.

[0029] The combination lock assembly includes a lock body disposed on the upper connecting part 1, a retractable bolt disposed on the lock body, and a limiting block disposed on the lower connecting part 2. In the locked state, the bolt extends and engages with the limiting block of the lower connecting part 2 to restrict the relative separation of the locking block 4 and the limiting groove 6. In the unlocked state, the bolt retracts, releasing the limiting, allowing the upper connecting part 1 and the lower connecting part 2 to separate through the locking block 4 from the limiting groove 6.

[0030] When the cabinet 14 is closed and the locking block 4 engages with the limiting groove 6, the combination lock is adjusted to the locked state. The bolt extends and engages with the limiting block, preventing the locking block 4 from disengaging from the limiting groove 6. Even if subjected to external impact, the locking block 4 cannot move, preventing the cabinet 14 from opening or closing accidentally. When unlocking is required, the correct password is entered, the bolt retracts, and the limiting of the locking block 4 is released. At this time, the upper connecting part 1 can be pulled normally to open or close. The design of the combination lock component does not affect the normal operation of the locking structure and works in conjunction with the locking structure, retaining the convenience of locking and closing while adding anti-theft function, thus improving the practicality of the product.

[0031] Meanwhile, a first zipper tooth 8 is fixed to one end of the zipper fabric 12, and the first zipper tooth 8 engages with the second zipper tooth 10 inside the box body 14. When it is necessary to install the inner lining fabric 9, align the second zipper tooth 10 of the inner lining fabric 9 with the first zipper tooth 8 of the zipper fabric 12, and pull the zipper head to achieve engagement between the two, thus completing the fixation of the inner lining fabric 9 to the upper frame 16 and the lower frame 17.

[0032] In summary, this convenient luggage frame assembly mechanism first fixes the clip 18 and zipper fabric 12 together, then pre-installs the connecting component 15 by passing it through the cavity 13 of the upper frame 16 and lower frame 17. Next, the upper frame 16 and lower frame 17 are respectively fitted into the annular mounting grooves 7 of the upper connecting part 1 and the lower connecting part 2, and the two ends of the frame are fixed by fasteners such as rivets 11 to prevent the frame from shifting. Then, the second zipper tooth 10 of the inner lining fabric 9 is engaged with the first zipper tooth 8 of the connecting component 15 to realize the assembly of the inner lining fabric 9. When the box 14 is closed, the trapezoidal cross-section locking block 4 and the inclined side of the limiting groove 6 guide the locking block 4 to slide precisely into the limiting groove 6 to complete the locking. At the same time, the sealing strip on the outer periphery of the locking block 4 and the limiting groove 6 are interference fit to achieve waterproof and dustproof sealing. The combination lock component can further lock the locking structure to prevent accidental opening and closing.

[0033] This utility model is not limited to the above-described embodiments. If any modifications or variations to this utility model do not depart from the spirit and scope of this utility model, and if such modifications and variations fall within the scope of the claims and equivalent technologies of this utility model, then this utility model also intends to include such modifications and variations.
