Technical Field
[0001] This utility model relates to the field of luggage wheel assembly technology, and in particular to a luggage wheel assembly that is easy to disassemble. Background Technology
[0002] Suitcase wheels are a core component that determines the travel experience, and their quality directly affects the smoothness and durability of the suitcase. High-quality wheels typically use wear-resistant rubber or polyurethane materials, which are not only quiet and smooth but also adaptable to various complex road surfaces such as cobblestones and pebbles. In terms of bearing design, double-row steel balls or high-precision bearings can effectively reduce friction and achieve 360° free steering. Some high-end wheels also have shock absorption functions, maintaining a smooth ride even on bumpy roads, making long-distance travel easier and less strenuous.
[0003] Most suitcase wheels on the market today are constructed by injection molding a central wheel core, then wrapping the edge of the wheel core with a soft rubber part that contacts the ground, and finally fixing the wheel core cover to the outside of the wheel hub with clips.
[0004] The following defects exist in suitcase wheelsets: during movement, the wheelsets are easily subjected to external impacts or heavy pressure, and the soft rubber parts and wheel core covers are prone to deformation and detachment, resulting in malfunctions. However, the wheelsets are often directly fixed to the suitcase, and damage to the wheelsets renders the entire suitcase unusable, making replacement costs high. Therefore, a suitcase wheelset that is easy to disassemble is proposed to solve the above problems. Utility Model Content

[0024] 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.
[0025] Reference Figures 1-3This utility model provides an embodiment of a conveniently detachable suitcase wheel set, comprising a wheel core body 1, a wheel body 2, and a support frame 3. The wheel body 2 is fixedly connected to the outer side wall of the wheel core body 1, and the support frame 3 is rotatably connected to the outer side wall of the wheel core body 1. The support frame 3 serves to support and connect the suitcase body, ensuring a stable connection between the wheel set and the suitcase body. An adjustment mechanism 4 and an auxiliary mechanism 5 are provided on the support frame 3. The adjustment mechanism 4 includes a support cylinder 42, which is fixedly connected to the top inner wall of the support frame 3. The support cylinder 42 serves as the wheel set. The important component connected to the box body is fixedly connected to the support frame 3, laying the foundation for subsequent connection with the box body fixing column 44. The top inner wall of the support cylinder 42 is provided with a socket 43, and the box body fixing column 44 is slidably connected to the side inner wall of the socket 43. The top inner wall of the support frame 3 is slidably connected to an adjusting plate 46. The left outer wall of the adjusting plate 46 is fixedly connected to a plug rod 47. Under the action of the adjusting plate 46, the plug rod 47 can be inserted into or pulled out of the box body fixing column 44, which plays the role of locking or unlocking the connection between the wheel assembly and the box body. The right outer wall of the adjusting plate 46 is fixedly connected to a compression spring 48.
[0026] Reference Figures 2-4 The wheel body 2 includes a soft rubber and a wheel core cover. An integrated process connector 41 is fixedly connected to the inner side wall of the wheel body 2. The integrated process connector 41 is designed to integrate the wheel body 2, the soft rubber, and the wheel core cover into one piece, completely wrapping the wheel core body 1 with the soft rubber. Through the integrated design, the soft rubber completely wraps the wheel core, so the impact resistance is better and it is less likely to fall off and fail under impact. In addition, compared with the traditional separately manufactured wheel core cover assembly, it can reduce problems such as seams and color difference. The outer side wall of the box fixing column 44 is fixedly connected to a directional plate 45, and the top outer wall of the support frame 3 is fitted with six The side groove and the directional disc 45 are snapped into the inner side wall of the hexagonal groove. The insertion rod 47 passes through the inner right side wall of the housing fixing post 44. The end of the compression spring 48 away from the adjustment plate 46 is fixedly connected to the inner right side wall of the compression spring 48. The outer walls on both sides of the adjustment plate 46 are fixedly connected with frosted pads. The frosted pads increase the friction of the surface of the adjustment plate 46, making it easier for the user to pull the adjustment plate 46 and making the operation more effortless. The outer right side wall of the support frame 3 is fixedly connected with a directional mark 49. The directional mark 49 provides a clear guide for the installation direction of the wheelset, making it easy for the user to accurately install the wheelset and avoid affecting the use due to incorrect installation direction.
[0027] Reference Figures 3-4The auxiliary mechanism 5 includes a chute 51, which is located on the right inner wall of the support frame 3. A movable plate 52 is slidably connected to the left inner wall of the chute 51. A sliding plate 53 is fixedly connected to the right outer wall of the movable plate 52. A scraper 54 is fixedly connected to the right outer wall of the sliding plate 53. The movable plate 52 slides within the chute 51, and its sliding motion drives the sliding plate 53 and the scraper 54 to move, thereby achieving the cleaning function of the wheel body 2. A telescopic spring 55 is fixedly connected to the right outer wall of the movable plate 52. The sliding plate 53 passes through the right outer wall of the support frame 3. The scraper 54 contacts the side outer wall of the wheel body 2. There are two wheel bodies 2. The length of the telescopic spring 55 is adapted to the width of the two wheel bodies 2. This size design ensures that the telescopic spring 55 can provide appropriate pressure to the scraper 54, so that the scraper 54 contacts the two wheel bodies 2 evenly, ensuring the cleaning effect.
[0028] Working principle: When a single wheel body 2 is damaged, the suitcase is laid flat beforehand. Then, the adjusting plate 46 is pulled to move the insert rod 47, which separates from the suitcase fixing post 44. This then separates the support cylinder 42 from the suitcase fixing post 44, allowing for easy separation of the single wheel core body 1 and wheel body 2 from the suitcase. The support cylinder 42 on the new support frame 3 is then reinserted into the suitcase fixing post 44. No other fixing tools are needed for quick installation. Simultaneously, when the wheel body 2 supports the suitcase on the ground, since the ground usually has some dirt stuck to it, as the wheel body 2 rotates, the scraper 54, under the thrust of the telescopic spring 55 pushing the movable plate 52, causes the sliding plate 53 to continuously scrape the scraper 54. This ensures that the scraper 54 is always in flexible contact with the surface of the wheel body 2, effectively scraping away some of the impurities. This prevents the wheel body 2 from accumulating too much dirt, which could cause the suitcase to shake or move along a difficult path, affecting overall use.
[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
