Description

Technical Field

[0001] This utility model relates to the field of drawer slide technology, and in particular to a movable slide with a reinforced structure and a three-section concealed slide, which can be widely used in sliding parts of furniture such as drawers. Background Technology

[0002] Drawer slides are hardware accessories used on furniture cabinets. Existing drawer slides generally include two-section and three-section slides. Two-section slides include a sliding rail and a fixed rail, while three-section slides generally include a sliding rail, a center rail, and a fixed rail. Traditionally, the end of the sliding rail is usually integrally formed with a hook structure. This hook engages with the connector at the bottom of the drawer to fix and move the drawer. Although this design is simple in structure, it has the following problems in actual use: First, the hook structure is directly cut into the end of the sliding rail, drastically weakening the cross-section of the hook area, leading to an increased stress concentration coefficient. When the drawer is loaded with heavy objects, the end of the sliding rail is prone to outward deformation, causing the drawer to sink, jam, or even causing the ball bearings to fall out. Second, when the drawer is subjected to vertical impact loads, the thin end of the sliding rail cannot effectively distribute the stress, and excessive deformation may cause the entire slide system to fail.

[0003] Existing technologies attempt to address this issue by increasing the overall wall thickness of the sliding rail, but this leads to increased cost and sliding resistance, contradicting the trend towards thinner, lighter concealed rails. As modern furniture demands greater drawer load-bearing capacity and users expect longer lifespans for sliding rails, the problem of insufficient strength at the sliding rail ends is becoming increasingly prominent. Utility Model Content

[0004] To address the technical problem that when drawers are loaded with heavy objects, the ends of the sliding rails are prone to outward deformation, causing the drawers to sink, jam, or even the entire slide rail system to fail due to excessive deformation, this utility model provides a sliding rail with a reinforced structure and a three-section concealed rail.

[0005] In a first aspect, the present invention provides a movable rail with a reinforced structure, comprising a movable rail body, a reinforced structure provided at one end of the movable rail body, the reinforced structure comprising at least one reinforced plate, the reinforced plate covering the top of one end of the movable rail body to maintain the shape of the end of the movable rail body, and a hook provided at the top of the reinforced plate for fixing to a drawer.

[0006] As a further improvement to the above solution, the reinforcing plate is inverted L-shaped, with the inner side of the top wall of the reinforcing plate connected to the top wall of the movable rail body, and the inner side wall of the reinforcing plate connected to the outer side wall of the movable rail body.

[0007] As a further improvement to the above solution, the reinforcing plate is provided in two sets, with the two sets of reinforcing plates respectively facing each other on the left and right outer sides of the movable rail body and on both sides of the outer top surface of the movable rail body.

[0008] As a further improvement to the above solution, the reinforcing plate is inverted U-shaped and covers the top of one end of the movable rail body. The inner side of the top wall of the reinforcing plate is connected to the top wall of the movable rail body, and the inner side wall of the reinforcing plate is connected to the outer side wall of the movable rail body to prevent the end of the movable rail body from expanding outward and deforming.

[0009] As a further improvement to the above solution, the hook includes a connecting part and a hook part. One end of the connecting part is connected to the reinforcing plate, and the other end of the connecting part is connected to the hook part. The hook part is parallel to the top surface of the movable rail body.

[0010] As a further improvement to the above solution, the thickness of the reinforcing plate is greater than the wall thickness of the movable rail body.

[0011] As a further improvement to the above solution, the ratio of the height of the reinforcing plate to the height of the movable rail body is in the range of 1:3 to 4:5.

[0012] As a further improvement to the above solution, the reinforcing plate is welded to the top wall of the movable rail body via the inner side of its top wall, and the inner side wall of the reinforcing plate is welded to the outer side wall of the movable rail body.

[0013] As a further improvement to the above solution, the reinforcing structure is made of galvanized sheet metal, and its tensile strength is greater than that of the movable rail body.

[0014] Secondly, this utility model also provides a three-section concealed rail, including a fixed rail and a middle rail, and also includes a movable rail with a reinforced structure as described in the first aspect above. The fixed rail is used to be fixedly installed on the side panel of the cabinet, the middle rail is slidably connected to the fixed rail, and the movable rail is slidably connected to the middle rail.

[0015] This utility model discloses a sliding rail with a reinforced structure, comprising a sliding rail body and a reinforcing structure at one end of the sliding rail body. The reinforcing structure includes at least one reinforcing plate, which covers the top of one end of the sliding rail body to maintain the shape of the end of the sliding rail body and ensure that the rail will not fall off under heavy pressure. A hook for fixing to a drawer is provided at the top of the reinforcing plate. By adding an independent reinforcing structure to the end of the sliding rail body and placing the hook at the top of the reinforcing plate, the material weakening problem caused by directly adding a hook to the end of the sliding rail body is avoided, significantly improving the load-bearing capacity of the end of the sliding rail body.

[0016] In addition, the reinforcing plate in this utility model is made of high-strength material and its thickness is greater than that of the sliding rail body. It can effectively disperse the stress generated by the drawer load and prevent the sliding rail body from expanding and deforming. By optimizing the ratio of the length of the reinforcing structure to the length of the sliding rail body, the reinforcing effect is ensured while avoiding material waste and weight increase. Moreover, without changing the main body size of the sliding rail body, the load-bearing capacity can be improved by only local reinforcement, which is in line with the development trend of thinner and lighter concealed rails.

[0017] The three-section concealed rail in this invention uses the movable rail described in this application, avoiding the material weakening problem caused by directly opening hooks at the ends of the movable rail body, and significantly improving the load-bearing capacity at the ends of the movable rail body. Moreover, without changing the main dimensions of the movable rail body, the load-bearing capacity can be improved only through local reinforcement, which is in line with the development trend of thinner and lighter concealed rails.

[0027] Example 1: Figure 1 This is a schematic diagram of the structure of the movable track with a reinforced structure according to Embodiment 1 of this utility model application; Figure 2 for Figure 1 A magnified diagram of A in the middle, for reference. Figure 1 and Figure 2A sliding rail with a reinforced structure includes a sliding rail body 100. A reinforcing structure 200 is provided at one end of the sliding rail body 100. The reinforcing structure 200 includes at least one reinforcing plate, which covers the top of one end of the sliding rail body 100 to maintain the shape of the end of the sliding rail body 100 and ensure that the rail will not fall off under heavy pressure. A hook 300 for fixing to a drawer is provided at the top of the reinforcing plate.

[0028] In this embodiment, a limiting structure 110 is provided at one end of the movable rail body 100. The limiting structure 110 is V-shaped. When the movable rail body 100 slides to the end of the drawer cabinet outlet, it is limited by the limiting structure 110 and the drawer fixed rail to prevent the movable rail body 100 from slipping off the fixed rail.

[0029] Figure 3 This is a schematic diagram of the reinforcing structure of Embodiment 1 of this utility model application, with reference to... Figures 1 to 3 In this embodiment, the reinforcing plate is inverted L-shaped, with the inner side of the top wall of the reinforcing plate connected to the top wall of the movable rail body 100, and the inner side wall of the reinforcing plate connected to the outer side wall of the movable rail body 100.

[0030] In this embodiment, preferably, two sets of reinforcing plates are provided, including a first reinforcing plate 210 and a second reinforcing plate 220. The first reinforcing plate 210 and the second reinforcing plate 220 are respectively disposed facing each other on the left and right outer sides and the outer top surface of the movable rail body 100. A hook 300 is provided at one end of the horizontal plate of the first reinforcing plate 210. Preferably, the length of the horizontal plate of the first reinforcing plate 210 is longer than the length of the horizontal plate of the second reinforcing plate 220. Because the first reinforcing plate 210 is provided with the hook 300, the contact area between the first reinforcing plate 210 and the movable rail body 100 is increased, thus more effectively dispersing the stress generated by the drawer's pulling motion.

[0031] The hook 300 includes a connecting part 310 and a hook part 320. One end of the connecting part 310 is connected to the horizontal plate of the first reinforcing plate 210, and the other end of the connecting part 310 is connected to the hook part 320. The hook part 320 is parallel to the top surface of the movable rail body 100. Specifically, a guide slope 321 is provided on one end of the hook part 320 along the drawer to facilitate the alignment operation during drawer installation and improve assembly efficiency.

[0032] Specifically, the corner 230 between the horizontal and vertical plates of the reinforcing plate adopts an arc-shaped transition surface, which can effectively reduce the stress of the sliding rail body 100 on the corner of the reinforcing plate during the use of the drawer, reduce local stress, and thus significantly improve the life of the reinforcing plate under the impact and vibration of the sliding rail body 100.

[0033] In this embodiment, first riveting holes 240 are provided on the horizontal and vertical plates of the first reinforcing plate 210 and the horizontal and vertical plates of the second reinforcing plate 220. Correspondingly, a second riveting hole (not shown in the figure) is provided on the side of the movable rail body 100 corresponding to the first riveting hole 240 of the reinforcing plate. The reinforcing plate and the movable rail body 100 are fixedly connected by rivets passing through the first riveting hole 240 and the second riveting hole in sequence.

[0034] In an optional embodiment, the reinforcing plate is welded to the top wall of the movable rail body 100 via the inner side of the top wall of the reinforcing plate, and the inner side wall of the reinforcing plate is welded to the outer side wall of the movable rail body 100.

[0035] Example 2: Figure 4 This is a schematic diagram of the movable track with a reinforced structure according to Embodiment 2 of this utility model application. Figure 5 This is a schematic diagram of the reinforcing structure in Embodiment 2 of this utility model application, for reference. Figure 4 and Figure 5 The difference between Embodiment 2 and Embodiment 1 is that the reinforcing structure 200 in Embodiment 2 includes a reinforcing plate. The reinforcing plate is in the shape of an inverted U and is placed on the top of one end of the movable rail body 100. The inner side of the top wall of the reinforcing plate is connected to the top wall of the movable rail body 100, and the inner side wall of the reinforcing plate is connected to the outer side wall of the movable rail body 100 to prevent the end of the movable rail body 100 from expanding outward and deforming.

[0036] The corner 230 between the horizontal and vertical plates of the reinforcing plate adopts an arc-shaped transition surface, which can effectively reduce the stress of the moving rail body 100 on the corner of the reinforcing plate during the use of the drawer, reduce local stress, and thus significantly improve the life of the reinforcing plate under the impact and vibration of the moving rail body 100.

[0037] A hook 300 is provided at one end of the horizontal plate of the reinforcing plate. The hook 300 includes a connecting part 310 and a hook part 320. One end of the connecting part 310 is connected to the horizontal plate of the reinforcing plate, and the other end of the connecting part 310 is connected to the hook part 320. The hook part 320 is parallel to the top surface of the movable rail body 100. Specifically, a guide slope 321 is provided at one end of the hook part 320 along the drawer to facilitate the alignment operation during drawer installation and improve assembly efficiency.

[0038] In this embodiment, first riveting holes 240 are provided on both the horizontal and vertical plates of the reinforcing plate. Correspondingly, a second riveting hole (not shown in the figure) is provided on the side of the movable rail body 100 corresponding to the first riveting hole 240 of the reinforcing plate. The reinforcing plate and the movable rail body 100 are fixedly connected by rivets passing through the first riveting hole 240 and the second riveting hole in sequence.

[0039] In an optional embodiment, the reinforcing plate is welded to the top wall of the movable rail body 100 via the inner side of the top wall of the reinforcing plate, and the inner side wall of the reinforcing plate is welded to the outer side wall of the movable rail body 100.

[0040] Preferably, the reinforcing structure 200 in Embodiments 1 and 2 is made of galvanized sheet metal, and its tensile strength is greater than that of the movable rail body 100. The thickness of the reinforcing plate is greater than the wall thickness of the movable rail body 100, which can effectively disperse the stress generated by the drawer load and prevent the movable rail body 100 from expanding and deforming outward.

[0041] Preferably, the height of the reinforcing plate in Embodiment 1 and Embodiment 2 is in the range of 1:3 to 4:5 relative to the height of the movable rail body 100. This ensures that the movable rail body 100 is prevented from expanding and deforming outwards while maintaining a reinforcing effect, thus avoiding material waste and weight increase, making the movable rail lighter.

[0042] This utility model discloses a sliding rail with a reinforced structure, comprising a sliding rail body 100, and a reinforcing structure 200 at one end of the sliding rail body 100. The reinforcing structure 200 includes at least one reinforcing plate, which covers the top of one end of the sliding rail body 100 to maintain the shape of the end of the sliding rail body 100 and ensure that the rail will not fall off under heavy pressure. A hook 300 for fixing to a drawer is provided at the top of the reinforcing plate. By adding an independent reinforcing structure 200 at the end of the sliding rail body 100 and setting the hook 300 at the top of the reinforcing plate, the material weakening problem caused by directly opening the hook at the end of the sliding rail is avoided, and the load-bearing capacity of the end of the sliding rail is significantly improved.

[0043] In addition, the reinforcing plate in this utility model is made of high-strength material and its thickness is greater than that of the sliding rail wall, which can effectively disperse the stress generated by the drawer load and prevent the sliding rail body from expanding and deforming. By optimizing the ratio of the length of the reinforcing structure to the length of the sliding rail body, the reinforcing effect is ensured while avoiding material waste and weight increase. Moreover, without changing the main body size of the sliding rail body, the load-bearing capacity can be increased by more than 30% by local reinforcement, which is in line with the development trend of thinner and lighter concealed rails.

[0044] Example 3: Figure 6 This is a schematic diagram of the structure of the three-section hidden rail in Embodiment 3 of this utility model application, for reference. Figure 6 A three-section concealed rail includes a movable rail 10 with a reinforced structure as described in Embodiment 1 or Embodiment 2 above, and further includes a middle rail 20 and a fixed rail 30. The fixed rail 30 is used for fixed installation on the side panel of the cabinet. The middle rail 20 is slidably connected to the fixed rail 30, and the movable rail 10 is slidably connected to the middle rail 20. The connections between the movable rail 10 and the middle rail 20 and the fixed rail 30 are prior art and will not be described further here.

[0045] The three-section concealed rail in this embodiment uses the movable rail of Embodiment 1 or Embodiment 2, avoiding the material weakening problem caused by directly opening hooks at the ends of the movable rail body, and significantly improving the load-bearing capacity at the ends of the movable rail body. Moreover, without changing the main dimensions of the movable rail body, the load-bearing capacity can be improved only through local reinforcement, which is in line with the development trend of thinner and lighter concealed rails.

The above are merely preferred embodiments of this application and do not limit the patent scope of this application.
