Description

Technical Field

[0001] This utility model relates to the field of home hardware accessories technology, specifically a concealed heavy-duty jewelry display cabinet guide rail. Background Technology

[0002] Drawers are a common storage unit in cabinetry, and their smooth sliding operation relies on drawer slides. Traditional drawer slides, such as common ball bearing slides or bottom-mounted slides, are widely used in some ordinary household furniture. However, with the rise of high-end custom furniture, especially jewelry display cases and luxury goods display cases, higher requirements have been placed on the performance and installation efficiency of drawer slides.

[0003] Firstly, in applications such as jewelry display cases, the overall aesthetics are of paramount importance. Users do not want to see exposed, complex drawer slides when the drawer is open, as this would disrupt the clean and sophisticated feel of the display case. Therefore, concealed drawer slides have emerged. While existing concealed drawer slides strive to make the slides invisible when the drawer is closed, some slide structures or mounting components may still be exposed when the drawer is open, failing to achieve the ideal of "complete concealment" or an ultra-simple visual effect.

[0004] Secondly, drawers in jewelry display cases often need to support heavy, valuable items, such as large quantities of jewelry, watches, or related display props. Therefore, there are specific requirements for the load-bearing capacity of the drawer slides, i.e., "heavy-duty" slides. Ordinary light-duty slides cannot meet the long-term stable operation under such high loads. While some heavy-duty slides have strong load-bearing capacity, their structures are often more complex and bulky, making it difficult to achieve a good concealment effect.

[0005] More importantly, some existing jewelry display case rails or similar heavy-duty rails fail to adequately consider the long-term impact of the cleanliness of the working environment on their performance. Specifically, the core rolling components of these rails, such as guide wheels and load-bearing pulleys, often have their working surfaces or rolling tracks partially or completely exposed. This exposed design has the following significant drawbacks: 1. In actual use, dust, fibers, and small debris easily accumulate on the exposed pulley and track surfaces. For applications like jewelry display cases that require a certain level of cleanliness, even tiny particles, once they enter the gaps in the rolling fit, will significantly increase frictional resistance, causing drawers to be difficult to push and pull, producing abnormal noises, or even jamming.

[0006] 2. When contaminants mix with lubricating grease, they form a viscous oily residue, further deteriorating the working condition of the guide rails. Users need to clean and maintain them frequently, increasing operating costs. In the long run, continuous wear and contamination will significantly shorten the lifespan of the guide rails, affecting the normal use of the display case.

[0007] 3. Exposed pulleys and the dust and oil stains on them, even if they do not affect short-term use, will give users a direct impression of uncleanliness and low quality, which is contrary to the high-end positioning pursued by jewelry display cases. Therefore, it is necessary to make further improvements. Utility Model Content

[0008] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a jewelry display case guide rail that is simple in structure, low in manufacturing cost, can meet heavy load requirements, achieve a good concealment effect, and effectively protect its core rolling components from external environmental pollution, thereby ensuring long-term smooth and stable operation.

[0009] The purpose of this utility model is achieved in the following way: a concealed heavy-duty jewelry display cabinet guide rail, which includes a guide rail fixed on the drawer and a sliding block fixed on the cabinet body. The sliding block is provided with a plurality of load-bearing pulleys on the inner side facing the guide rail. The load-bearing pulleys roll in cooperation with the bearing surface of the guide rail to bear the vertical gravity.

[0010] The sliding block is also provided with several guide pulleys, which roll in cooperation with the guide surface of the guide rail to bear the lateral force and limit the lateral movement of the sliding block within the guide rail.

[0011] Furthermore: at least four load-bearing pulleys are provided, distributed at the four corners of the inner side of the sliding block, and the outer circle of the load-bearing pulley protrudes from the side of the sliding block on one side.

[0012] Furthermore, at least four guide pulleys are provided, distributed at the four corners of the inner side of the sliding block.

[0013] Furthermore, guide wheel seats that bend toward the guide rail are provided at the four corners of the inner side of the sliding block, and the guide pulley is mounted on the guide wheel seats.

[0014] Furthermore, the outer surface of the sliding block is covered with a connecting plate, through which the sliding block is connected to the cabinet.

[0015] Furthermore, the load-bearing pulley and guide pulley are bearings mounted on the sliding block by rivets.

[0016] Furthermore, the guide rail is covered with end caps at both ends.

[0017] The beneficial effects of this utility model are: 1. Simple structure, low manufacturing cost, and improved market competitiveness.

[0018] 2. This utility model designs by placing the load-bearing pulley and guide pulley on the inner side of the sliding block facing the guide rail, and making them roll-fit with the bearing surface and guide surface of the guide rail. This design ensures that during operation, most of the pulley's structure and the contact track with the guide rail are shielded and protected by the structure of the guide rail and the sliding block. Compared to existing technologies where most guide wheels are exposed, this utility model significantly reduces the chance of dust, debris, and other contaminants entering the contact area between the pulley and the rail, thereby avoiding problems such as increased friction, stalling, or abnormal noise caused by contaminants.

[0019] 3. In this case, the guide rails are covered with end caps at both ends, further preventing contaminants from entering from the ends of the guide rails and providing more comprehensive protection for the internal rolling components. This structural design not only ensures the smoothness and quietness of the drawer's long-term sliding operation, but also greatly reduces the frequency of cleaning and maintenance, extending the overall service life of the guide rails.

[0020] 4. The guide rail is fixed to the drawer, and the sliding block is fixed to the cabinet body. The core rolling components and matching tracks are all housed between the guide rail and the sliding block. When the drawer is closed, the guide rail structure can be completely hidden. Even when the drawer is open, because the main moving parts, such as the casters, are located inside the sliding block and cooperate with the inside of the guide rail, the exterior of the guide rail is almost invisible or only reveals a clean, simple outer surface, avoiding the cluttered look of traditional guide rails due to exposed structure.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings. A concealed heavy-duty jewelry display cabinet guide rail includes a guide rail 1 fixed to a drawer and a sliding block 2 fixed to the cabinet body. The sliding block 2 has a plurality of load-bearing pulleys 3 arranged on its inner side facing the guide rail 1. The load-bearing pulleys 3 roll in cooperation with the bearing surface of the guide rail 1 to bear the vertical gravity. The sliding block 2 is also provided with a plurality of guide pulleys 4. The guide pulleys 4 roll in cooperation with the guide surface of the guide rail 1 to bear the lateral force and limit the lateral movement of the sliding block 2 within the guide rail 1.

[0027] In this embodiment: the guide rail 1 is attached to the drawer, while the sliding block 2 is fixed to the cabinet. When the drawer is pushed or pulled, the guide rail 1 moves relative to the fixed sliding block 2. This relative movement is achieved by two different sets of pulleys: the load-bearing pulley 3 is installed on the inside of the sliding block 2, i.e., the side facing the guide rail 1. They contact and roll with a specific "bearing surface" on the guide rail 1. Their main function is to bear the vertical weight from the drawer and its contents.

[0028] The guide pulleys 4 are mounted on the sliding blocks 2, and they contact and roll with a specific "guide surface" on the guide rail 1. Their main function is to withstand lateral forces, such as slight wobbling or uneven force generated during pushing and pulling, and to ensure that the lateral movement of the sliding blocks 2 inside the guide rail 1 is constrained, that is, to keep the drawer moving in a straight line.

[0029] In this embodiment, the load-bearing pulley that bears vertical gravity and the guide pulley that bears lateral force and guides are separated. This allows for targeted optimization of the pulley and track design, resulting in more efficient force transmission and a more stable structure.

[0030] Meanwhile, setting the pulley on the "inner side" of the sliding block 2 facing the guide rail 1 lays the foundation for achieving the overall "hidden" effect, because the working parts are located between the guide rail and the slider and are not easily seen from the outside.

[0031] At least four load-bearing pulleys 3 are provided, distributed at the four corners of the inner side of the sliding block 2, and the outer circle of the load-bearing pulley 3 protrudes from the side of the sliding block 2 on one side.

[0032] In this embodiment, the layout of the four corners allows the vertical load to be distributed more evenly on the sliding block, providing a more stable support platform, significantly improving the overall load-bearing capacity of the guide rail, and preventing the drawer from tilting or deforming under heavy load.

[0033] At least four guide pulleys 4 are provided, distributed at the four corners of the inner side of the sliding block 2.

[0034] Similarly, at least four guide rollers are provided, and they are also distributed at the "four corners" of the inner side of the sliding block 2. This arrangement ensures that the sliding block is constrained at multiple points in the lateral direction. Placing guide rollers at the four corners of the sliding block more effectively resists lateral forces from different directions, preventing the drawer from wobbling, shifting, or jamming during pushing and pulling, ensuring the drawer moves precisely in a straight line. Multi-point guidance gives the entire system better resistance to lateral impacts or uneven forces, protecting the guide rail structure.

[0035] In one embodiment, guide wheel seats 5, bent towards the guide rail 1, are provided at the four corners of the inner side of the sliding block 2, and the guide pulley 4 is mounted on the guide wheel seats 5. This bent structure allows the guide pulley to precisely engage with the guide surface of the guide rail 1 at a suitable angle and position. The bent design of the guide wheel seats ensures that the guide pulley contacts the guide surface of the guide rail at the optimal angle and predetermined position, thereby achieving more effective guidance and less friction. The dedicated guide wheel seats provide a stable mounting base for the guide pulley, which helps to improve the rigidity of the overall structure and the reliability of guidance, and may make the structure more compact.

[0036] In one embodiment: the outer surface of the sliding block 2 is covered with a connecting plate 6, and the sliding block is connected to the cabinet through the connecting plate.

[0037] In one embodiment, the load-bearing pulley 3 and guide pulley 4 are bearings mounted on the sliding block 2 by rivets. These bearings are permanently fixed to the sliding block 2 using this rivet connection method. Using bearings as pulleys significantly reduces sliding friction, allowing the drawer to be pushed and pulled very smoothly and effortlessly, even under heavy loads. At the same time, the bearings are designed to withstand high loads and long-term operation, exhibiting good wear resistance and service life. The rivet connection is a robust and reliable fixing method, ensuring that the bearings will not loosen during long-term use.

[0038] In one embodiment, the guide rail 1 is covered with end caps 7 at both ends. These end caps are installed at both ends of the guide rail 1, sealing their openings. The end caps effectively prevent dust, debris, and other contaminants from entering the working area of ​​the pulley from both ends of the guide rail, keeping the rail clean and thus avoiding poor sliding, accelerated wear, or abnormal noise caused by contamination. At the same time, the end caps make the ends of the guide rail look more complete and aesthetically pleasing, and may also cover the sharp edges of the cut ends of the guide rail, improving safety during use.

[0039] In summary, the drawer slide system consists of a guide rail 1 fixed to the drawer and a sliding block 2 fixed to the cabinet. The push-pull movement of the drawer is the linear reciprocating movement of the guide rail 1 relative to the sliding block 2.

[0040] Among them, the sliding block 2 has two types of rolling components, load-bearing pulleys 3 and guide pulleys 4, cleverly arranged on its inner side facing the guide rail 1. They are all bearings and are firmly installed by rivets.

[0041] At least four load-bearing pulleys 3 are distributed at the four corners of the inner side of the sliding block 2, with their outer circles protruding and forming a rolling engagement with the specially designed "bearing surface" of the guide rail 1. These load-bearing pulleys are specifically responsible for bearing the vertical weight of the drawer and its contents, ensuring stable support and smooth movement of the drawer in the vertical direction.

[0042] At least four guide pulleys 4 are also distributed at the four corners of the inner side of the sliding block 2, and they are mounted on the guide wheel seats 5 that bend towards the guide rail 1. These guide pulleys form a rolling engagement with the specially designed "guide surface" of the guide rail 1, which is responsible for bearing the lateral force and precisely limiting the lateral movement of the sliding block 2 within the guide rail 1, preventing the drawer from shaking and ensuring that it moves stably and accurately along the predetermined trajectory.

[0043] To achieve a stable installation and a good appearance, the sliding block 2 is connected and fixed to the cabinet by the connecting plate 6 covering its outer surface.

[0044] To protect the internal rolling mechanism and improve durability, the guide rail 1 is covered with end caps 7 at both ends to effectively prevent contaminants from entering the interior of the rail, thereby ensuring the cleanliness of the pulleys and rails and maintaining smooth operation over a long period of time.

[0045] Compared to traditional technologies, this design achieves strong load-bearing capacity and precise guiding performance by separating the load-bearing pulleys and guide pulleys, and optimizing their quantity and layout, thus meeting heavy-duty requirements. Furthermore, the core rolling components are all located inside the sliding blocks and cooperate with the guide rails. Combined with the installation method of the connecting plates, the guide rails are well concealed after installation, enhancing the overall aesthetics of the display case. Therefore, this design can be widely adopted.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
