Description

Technical Field

[0001] This utility model relates to the field of luggage accessories technology, and in particular to a detachable luggage wheel. Background Technology

[0002] As an important component of travel bags, trolley cases, and luggage, the design and performance of luggage wheels directly affect the portability, durability, and user experience of the bags.

[0003] For example, Chinese utility model patent with publication number CN215837475U discloses a detachable wheel, whose fixing plate is fastened to the fixing part by screws. This installation method has many parts and the disassembly and assembly operation is cumbersome. In addition, the spring plate is reset by only a return spring, which is prone to jamming and the reset process is not smooth.

[0004] Therefore, it is necessary to improve upon the shortcomings of the existing technologies mentioned above. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a detachable bag wheel to address the shortcomings of the prior art, thereby solving the problems of numerous mounting parts, cumbersome disassembly and assembly, and easy jamming during resetting of the detachable wheel in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a detachable bag wheel, comprising a fixing part and a wheel part detachably connected to the fixing part, wherein the fixing part is provided with a limiting groove and a fixing plate, and a plug-in mechanism for fixing the two is provided between the fixing plate and the limiting groove.

[0007] By adopting the above technical solution, the plug-in mechanism replaces the traditional screw connection, reducing the number of parts, simplifying the installation structure, and making disassembly and assembly simpler and faster.

[0008] A further provision of the above technical solution is that the insertion mechanism includes locking feet at both ends of the bottom surface of the fixed plate and locking posts on both sides of the limiting groove. The locking posts are provided with locking holes, and the locking feet can be inserted into the locking holes with an interference fit.

[0009] By adopting the above technical solution, the connection between the fixed plate and the limiting groove is achieved by inserting the clips on the bottom surface of the fixed plate into the clip holes of the clip post. This ensures the stability of the connection between the fixed plate and the limiting groove, while also making disassembly and assembly simple and quick with fewer parts.

[0010] A further configuration of the above technical solution is as follows: a limiting plate is slidably connected within the limiting groove; one end of the limiting plate is provided with a limiting slot, and the other side is provided with a first return spring; one end of the first return spring abuts against the side of the limiting plate, and the other end abuts against the side wall of the limiting groove; the bottom of the fixing part is provided with a first mounting hole communicating with one end of the limiting groove; a disassembly connecting rod is transitionally connected to the first mounting hole; the upper end of the disassembly connecting rod is provided with a limiting slot that mates with the limiting slot; the bottom of the fixing part is provided with a second mounting hole communicating with the middle of the limiting groove; a top contact rod is clearance-fitted to the second mounting hole; the top of the top contact rod is provided with a first inclined surface; the bottom of the limiting plate is provided with a second inclined surface; when the top contact rod moves upward, the first inclined surface presses against the second inclined surface, causing the limiting plate to drive the limiting slot to disengage from the limiting slot; the end of the disassembly connecting rod away from the limiting slot is connected to the wheel part.

[0011] Using the above technical solution, during disassembly, push the top contact rod, and the top contact rod moves upward. The first inclined surface at the top of the rod presses against the second inclined surface at the bottom of the limiting plate, causing the limiting plate to disengage the limiting slot from the limiting groove. The disassembly and assembly connecting rod can then be removed from the first mounting hole, thereby separating the wheel part from the fixed part. During installation, the operation is reversed.

[0012] A further provision of the above technical solution is as follows: the limiting plate is provided with an avoidance through hole in the middle, the top center of the top contact rod and the bottom of the fixing plate are provided with corresponding first limiting posts, and a second reset spring passing through the avoidance through hole is sleeved between the two first limiting posts.

[0013] By adopting the above technical solution, the setting of the second reset spring enables the top contact rod to reset quickly, no longer relying on the first reset spring to act on the limit plate before pushing the top contact rod to reset, thus speeding up the reset speed, ensuring a smooth reset process, and making it less prone to jamming.

[0014] A further provision of the above technical solution is as follows: the side of the limiting plate is provided with a second limiting post for limiting the first reset spring, the side wall of the limiting groove is provided with a U-shaped groove for limiting the other end of the first reset spring, and the bottom surface of the fixing plate is provided with a limiting protrusion above the U-shaped groove.

[0015] By adopting the above technical solution, the second limiting post, U-shaped groove and limiting protrusion can effectively limit the two ends of the first reset spring, ensuring its stability and reliability during operation.

[0016] A further provision of the above technical solution is as follows: the bottom of the fixing part is provided with a fixing protrusion at the outer periphery of the first mounting hole; the wheel part includes a wheel and a wheel seat; the wheel seat is provided with a fixing boss that transitions with the inner side of the fixing protrusion; a T-shaped mounting groove is provided on one side of the fixing boss; and a mounting ring is provided at the lower end of the disassembly and assembly connecting rod. The mounting ring can slide into the center position of the fixing boss through the mounting groove.

[0017] Using the above technical solution, the fixed boss can be inserted into the fixed boss ring to fix the wheel seat circumferentially, while the mounting ring at the lower end of the disassembly and assembly connecting rod can be inserted into the mounting groove to fix the wheel seat axially. This achieves the goal of fixing the wheel seat to the fixed part, so that the wheel part and the fixed part can be quickly installed and connected stably.

[0018] A further provision of the above technical solution is that the top of the fixing part is provided with a plurality of third mounting holes for mounting to the body of the bag.

[0019] By adopting the above technical solution, the fixing part can be easily installed onto the body of the bag through the third mounting hole, thus realizing the connection between the wheel and the bag.

[0020] The beneficial effects achieved by this utility model are: the fixed part and the fixed plate are fixedly connected by plugging, thereby eliminating screws and making disassembly and assembly simple and quick; a second return spring is set between the top of the top contact rod and the bottom of the fixed plate, which enables the top contact rod to be quickly reset, no longer relying on the first return spring to act on the limit plate before pushing the top contact rod to reset, and the whole reset process is smooth and not prone to jamming.

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.

[0029] like Figure 1-4 As shown, a detachable bag wheel includes a fixing part 1 and a wheel part 7 detachably connected to the fixing part 1. The fixing part 1 is provided with a limiting groove 11 and a fixing plate 12. A plug-in mechanism for fixed connection is provided between the fixing plate 12 and the limiting groove 11. The plug-in mechanism includes locking feet 121 provided at both ends of the bottom surface of the fixing plate 12 and locking posts 13 provided on both sides of the limiting groove 11. The locking posts 13 are provided with locking holes 131, and the locking feet 121 can be inserted into the locking holes 131 with an interference fit.

[0030] like Figure 1-6As shown, a limiting plate 2 is slidably connected inside the limiting groove 11. One end of the limiting plate 2 is provided with a limiting slot 21, and the other side is provided with a first return spring 22. One end of the first return spring 22 abuts against the side of the limiting plate 2, and the other end abuts against the side wall of the limiting groove 11. The bottom of the fixing part 1 is provided with a first mounting hole 14 that communicates with one end of the limiting groove 11. A disassembly and assembly connecting rod 5 is connected to the first mounting hole 14 through a transition fit. The upper end of the disassembly and assembly connecting rod 5 is provided with a fitting that matches the limiting slot 21. The limiting slot 51 is fitted together. The bottom of the fixing part 1 is provided with a second mounting hole 15 that communicates with the middle of the limiting slot 11. The second mounting hole 15 is connected to the top contact rod 6 with clearance fit. The top of the top contact rod 6 is provided with a first inclined surface 61. The bottom of the limiting plate 2 is provided with a second inclined surface 25. When the top contact rod 6 moves upward, the first inclined surface 61 presses against the second inclined surface 25, which can cause the limiting plate 2 to drive the limiting slot 21 to disengage from the limiting slot 51. The end of the disassembly and assembly connecting rod 5 away from the limiting slot 51 is connected to the wheel part 7. The middle of the limiting plate 2 is provided with an avoidance through hole 23. The top middle of the top of the top contact rod 6 and the bottom of the fixing plate 12 are both provided with first limiting posts 3 with corresponding positions. A second return spring 4 passing through the avoidance through hole 23 is sleeved between the two first limiting posts 3. The side of the limiting plate 2 is provided with a second limiting post 24 to limit the first reset spring 22. The side wall of the limiting groove 11 is provided with a U-shaped groove 111 to limit the other end of the first reset spring 22. The bottom surface of the fixing plate 12 is provided with a limiting protrusion 122 above the U-shaped groove 111.

[0031] like Figure 1-3 As shown, the bottom of the fixing part 1 has a fixing protrusion 16 located on the outer periphery of the first mounting hole 14. The wheel part 7 includes a wheel 71 and a wheel seat 72. The wheel seat 72 has a fixing boss 721 that transitions into the inner side of the fixing protrusion 16. One side of the fixing boss 721 has a T-shaped mounting groove 722. The lower end of the detachable connecting rod 5 has a mounting ring 52. The mounting ring 52 can slide into the center position of the fixing boss 721 through the mounting groove 722. The top of the fixing part 1 has several third mounting holes 17 for mounting to the main body of the bag.

[0032] In the above embodiment, during installation, the fixing boss 721 of the wheel seat 72 is engaged with the fixing ring 16 of the fixing part 1, and the mounting ring 52 slides into the center position of the fixing boss 721 through the mounting groove 722. At this time, the limiting slot 21 engages with the limiting groove 51 to achieve fixation. During disassembly, the top contact rod 6 is pushed, and the top contact rod 6 moves upward. The first inclined surface 61 at its top presses against the second inclined surface 25 at the bottom of the limiting plate 2, causing the limiting plate 2 to drive the limiting slot 21 to disengage from the limiting groove 51. The disassembly and assembly connecting rod 5 can then be removed from the first mounting hole 14, thereby separating the wheel part 7 from the fixing part 1. This utility model achieves a fixed connection between the fixing part 1 and the fixing plate 12 by inserting the locking foot 121 on the bottom surface of the fixing plate 12 into the locking hole 131 of the locking post 13, making disassembly and assembly simple and quick. The setting of the second return spring 4 allows the top contact rod 6 to quickly return to its original position without relying on the indirect action of the first return spring 22, ensuring the smoothness of the return process.
