Abstract
Description
Technical Field
[0001] This utility model relates to the field of furniture technology, and in particular to a 180-degree corner cabinet mechanism. Background Technology
[0002] A corner cabinet is a storage unit specifically designed for kitchens, bathrooms, or other enclosed spaces. Its key feature is utilizing corner space, transforming the intersection of two walls into a practical storage area. Corner spaces are often difficult to utilize effectively, but corner cabinets maximize their use and increase overall storage capacity.
[0003] In the process of developing this application, the inventors discovered the following problems with the existing technology: Conventional corner cabinets are generally at a fixed angle. Because the cabinet doors are designed at a fixed angle and are not convenient to close completely, dust, grease, and other pollutants can easily enter the interior, causing stored items to become dirty and difficult to keep clean. Moreover, exposed items and cluttered placement may make the overall space look untidy and unsightly, affecting the living experience.
[0004] Therefore, those skilled in the art have provided a 180-degree corner cabinet mechanism to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a 180-degree rotating cabinet mechanism. When the user applies force to rotate the cabinet body, the guide wheel slides from one end of the guide rail to the other end, allowing the cabinet body to achieve a 180-degree orientation change, which can prevent dust, fumes and pollutants from entering the cabinet interior.
[0006] To achieve the above objectives, the present invention provides the following technical solution: A 180-degree corner cabinet mechanism includes an outer shell, a cabinet body, a movable plate, and a cover plate. A base is fixedly installed at the inner end of the upper end of the cabinet body. A guide rail is provided at the upper end of the base. A washer bearing is rotatably installed at the upper end of the base near the guide rail. A connecting post is provided at the inner end of the washer bearing. Slider blocks are fixedly installed on both sides of the rear of the upper end of the movable plate. A threaded post is threaded on the front side of the upper end of the movable plate. Slide rails are fixedly installed on both sides of the lower end of the cover plate. Buffer boxes are fixedly installed at the lower end of the cover plate near the opposite positions of the two slide rails. Buffer dampers are fixedly installed inside the two buffer boxes. Guide wheels are rotatably installed on one side of the lower end of the cover plate near the edge.
[0007] Furthermore, the upper end of the cover plate is fixedly connected to the outer shell, and the cabinet body is rotatably mounted on the inner side of the front end of the outer shell.
[0008] Furthermore, the movable plate is rotatably connected to the connecting column, and the two threaded columns are respectively fixedly connected to the two buffer dampers.
[0009] Furthermore, the two sliders are slidably disposed on the upper ends of the two slide rails, and the movable plate is rotatably disposed between the base and the cover plate.
[0010] Furthermore, the guide wheel is movably disposed at the inner end of the guide rail.
[0011] Furthermore, a through hole is provided on the lower end of the cover plate away from the guide wheel, and the connecting post is located at the lower end of the through hole.
[0012] This utility model has the following beneficial effects: This invention proposes a 180-degree corner cabinet mechanism. When the user applies force to rotate the cabinet body, this rotational action is first transmitted to the connected movable plate, causing it to rotate synchronously. Then, power is transmitted through the connecting column, causing the end-positioned bearing to rotate. Simultaneously, a guide wheel fixed to the lower end of the cover slides along a preset guide rail, working in conjunction with a slider mounted on the movable plate or cabinet components to form a motion constraint mechanism, effectively guiding the cabinet to rotate along a predetermined trajectory. During the entire rotation process, when the guide wheel slides from one end of the guide rail to the other, it indicates that the cabinet has achieved a precise 180-degree orientation change. Through power transmission and motion constraint mechanisms, the smooth and precise rotation of the cabinet is ensured, improving operational stability and reliability, and ensuring the accuracy of the cabinet's trajectory during rotation. Furthermore, after the cabinet body rotates, it prevents dust, grease, and pollutants from entering the cabinet interior, maintaining the cleanliness and aesthetics of the overall space.

[0015] 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.
[0016] Reference Figures 1-10 One embodiment provided by this utility model: A 180-degree corner cabinet mechanism includes an outer shell 1, a cabinet body 2, a movable plate 7, and a cover plate 11. A base 3 is fixedly mounted on the inner upper end of the cabinet body 2. A guide rail 4 is provided on the upper end of the base 3. A shim bearing 5 is rotatably mounted on the upper end of the base 3 near the guide rail 4. A connecting post 6 is provided on the inner end of the shim bearing 5. Slider blocks 8 are fixedly mounted on both sides of the rear upper end of the movable plate 7. A threaded post 9 is threaded on the front upper end of the movable plate 7. Slide rails 12 are fixedly mounted on both sides of the lower lower end of the cover plate 11. Buffer boxes 13 are fixedly mounted on the lower end of the cover plate 11 near the opposite positions of the two slide rails 12. A buffer damper 10 is fixedly installed at the inner end of each cover plate 11. A guide wheel 14 is rotatably installed on one side of the lower end of the cover plate 11 near the edge. The upper end of the cover plate 11 is fixedly connected to the outer shell 1. The cabinet body 2 is rotatably installed on the inner side of the front end of the outer shell 1. The movable plate 7 is rotatably connected to the connecting column 6. The two threaded columns 9 are fixedly connected to the two buffer dampers 10 respectively. The two sliders 8 are slidably installed on the upper end of the two slide rails 12. The movable plate 7 is rotatably installed between the base 3 and the cover plate 11. The guide wheel 14 is movably installed on the inner end of the guide rail 4. A through hole 15 is opened on the lower end of the cover plate 11 away from the guide wheel 14. The connecting column 6 is located at the lower end of the through hole 15.
[0017] Specifically, when the user applies force to rotate the cabinet body 2, this rotation action is first transmitted to the movable plate 7 connected to it, causing the movable plate 7 to rotate synchronously. The rotation of the movable plate 7 then transmits power through the connecting column 6 on it, driving the washer bearing 5 located at the end of the connecting column 6 to rotate. This bearing design is intended to reduce friction and ensure smooth power transmission. Meanwhile, in order to precisely guide and control the rotation trajectory of the cabinet, the guide wheel 14 fixed at the lower end of the cover plate 11 will slide along the interior of the preset guide rail 4, while the slider 8 installed on the movable plate 7 or related parts of the cabinet will move along the slide rail 12 accordingly. The sliding path of the guide wheel 14 in the guide rail 4 and the movement trajectory of the slider 8 on the slide rail 12 constitute a specific motion constraint mechanism to ensure the stability of the rotation. During the entire rotation stroke, when the guide wheel 14 smoothly slides from the starting side of the guide rail 4 to the opposite end position, it signifies that the cabinet body 2 has precisely completed a 180-degree orientation change. To prevent the cabinet from violently impacting the outer shell 1 due to inertia or excessive speed of operation when it rotates to the end position, the buffer damper 10 generates progressive resistance as the rotation approaches the end point, effectively absorbing kinetic energy and ensuring a smooth stop of rotation. In addition, to adapt to different usage habits or environmental requirements, the tightness of the internal mechanism of the buffer damper 10 can be finely adjusted by rotating the threaded column 9, thereby changing the magnitude of the damping force it provides, realizing customized optimization of the rotation speed buffering effect, and ultimately ensuring that the entire 180-degree turn process is both smooth and reliable and can be completed safely and stably.
[0018] Working principle: When the user applies force to rotate the cabinet body 2, this rotational action is first transmitted to the movable plate 7 connected to it, causing the movable plate 7 to rotate synchronously. The rotation of the movable plate 7 then transmits power through the connecting column 6 on it, driving the washer bearing 5 located at the end of the connecting column 6 to rotate. At the same time, the guide wheel 14 fixed to the lower end of the cover plate 11 will slide along the preset guide rail 4, and the slider 8 installed on the movable plate 7 or related parts of the cabinet will move along the slide rail 12 accordingly. When the guide wheel 14 smoothly slides from the starting side of the guide rail 4 to the opposite end position, it means that the cabinet body 2 has accurately completed a 180-degree orientation change.
[0019] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
