[0032] like Figure 1 As shown, a preferred embodiment of the present invention provides a slide rail device 100, including a fixed base 10, a movable rail 20, a mounting base 30, and a height adjustment component 40. The movable rail 20 is slidably mounted on the fixed base 10; the mounting base 30 is slidably connected to the movable rail 20, and the mounting base 30 is used to connect with a drawer 200 or other mounting device. Figure 1 (Only a portion of the structure of drawer 200 is shown); the height adjustment component 40 connects the movable rail 20 and the mounting base 30 to drive the mounting base 30 to move vertically relative to the movable rail 20, thereby adjusting the height position of the mounting base 30.
[0033] Please see also Figure 2 , Figure 3 and Figure 5In this embodiment, the movable rail 20 is provided with a mounting slot 21 for connecting to a drawer 200 or other mounting device. Specifically, a protrusion 23 is fixed on the movable rail 20, and the mounting slot 21 is provided on the protrusion 23 and extends vertically through the protrusion 23. The movable rail 20 is provided with a mating part 25, which is an oblong hole on the movable rail 20, and the length direction of the mating part 25 is parallel to the sliding direction of the movable rail 20. In this embodiment, the mating part 25 is located at one end of the movable rail 20, and the mating part 25 and the mounting slot 21 are spaced apart along the length direction of the movable rail 20.
[0034] Please see also Figure 4 The mounting base 30 has a connection slot 31 on its side facing away from the movable rail 20, which is connected to the mounted object. The connection slot 31 and the mounting slot 21 are spaced apart along the length of the movable rail 20. In this embodiment, the mounting base 30 includes a mounting plate 32 and a protrusion 33 fixed to the mounting plate 32 on its side facing away from the movable rail 20. The mounting plate 32 is slidably connected to the movable rail 20. Specifically, the movable rail 20 is fixed with a guide member 26, and the mounting plate 32 of the mounting base 30 has a guide groove 34 corresponding to the guide member 26. The length direction of the guide groove 34 is parallel to the vertical. The mounting base 30 is slidably fitted onto the guide member 26 through the guide groove 34 to guide the sliding of the mounting base 30. In this embodiment, at least one guide groove 34 is provided at each of the opposite ends of the mounting base 30, and the movable rail 20 has multiple guide members 26 that are slidably engaged with the guide groove 34, thereby making the sliding of the mounting base 30 smoother. The guide member 26 can be a rivet vertically fixed to the movable rail 20. The rivet head is located on the side of the mounting plate 32 facing away from the movable rail 20, and the outer diameter of the rivet head is larger than the width of the guide groove 34. This allows it to both guide the sliding of the mounting base 30 and prevent the mounting base 30 from detaching from the movable rail 20. The protrusions 33 and the bumps 23 are spaced apart along the length of the movable rail 20. In this embodiment, the protrusions 33 are located between the guide grooves 34 at opposite ends of the mounting base 30. The connecting slot 31 is provided on the protrusions 33 and extends vertically through them.
[0035] The height adjustment component 40 connects the movable rail 20 to the mounting plate 32. Please refer to the following: Figure 6In this embodiment, the height adjustment component 40 is a rotary cam rotatably mounted on the mounting base 30. When the height adjustment component 40 is subjected to force and rotates, it engages with the mating part 25 to drive the mounting base 30 to move vertically relative to the movable rail 20. Specifically, the height adjustment component 40 includes a rotating disk 41 and a rotating shaft 43 vertically fixed to the end face of the rotating disk 41. The center of the rotating shaft 43 is eccentrically positioned relative to the center of the rotating disk 41. The rotating shaft 43 is rotatably connected to the mounting plate 32 of the mounting base 30, specifically, the mounting plate 32 of the mounting base 30 has a through hole 35, through which the rotating shaft 43 rotatably passes. The rotating disk 41 is movably mounted within the mating part 25, and the outer peripheral surface of the rotating disk 41 slides in contact with the groove wall of the mating part 25. Under the action of external force, the rotating shaft 43 can rotate within the hole 35. Through the engagement of the rotating disk 41 and the mating part 25, the mounting base 30 is driven to reciprocate vertically, thereby adjusting the height position of the mounting base 30. To facilitate the rotation of the rotating shaft 43, in this embodiment, a screwdriver groove 45 is recessed on the end face of the rotating shaft 43 away from the rotating disk 41 for engaging with a screwdriver. The screwdriver groove 45 is approximately hexagonal in shape. In use, the rotating shaft 43 can be rotated by engaging the screwdriver with the screwdriver groove 45, making it convenient to use. It is understood that in other embodiments, other shapes of screwdriver grooves 45 may be used, such as Phillips head grooves, and this invention is not limited thereto.
[0036] In this embodiment, the slide rail device 100 further includes a locking screw 50 for locking the mounting base 30 at the required height position. Specifically, the movable rail 20 is provided with a screw hole 27, which is spaced apart from the mounting slot 21 and the guide member 26. The mounting plate 32 of the mounting base 30 is provided with a sliding hole 36 corresponding to the screw hole 27, and the length direction of the sliding hole 36 is parallel to the vertical. The locking screw 50 includes a screw head 51 and a screw rod portion 53 that is fixedly connected to the screw head 51. The screw rod portion 53 passes through the sliding hole 36 and is threadedly connected to the screw hole 27. The outer diameter of the screw rod portion 53 of the locking screw 50 is smaller than the length of the sliding hole 36 so that the mounting base 30 can be moved vertically under force. When the locking screw 50 is rotated under force, the mounting base 30 can be locked or released by the screw head 51 of the locking screw 50: when the mounting base 30 is in the locked state, the screw head 51 of the locking screw 50 abuts against the mounting plate 32 of the mounting base 30 to clamp the mounting base 30 onto the movable rail 20, thereby locking the mounting base 30; when the mounting base 30 is in the released state, the screw head 51 of the locking screw 50 separates from the mounting plate 32 of the mounting base 30, thereby allowing the mounting base 30 to be moved vertically under force, thereby adjusting the height position.
[0037] The present invention also provides a refrigerator using the above-mentioned slide rail device 100. The refrigerator includes a cabinet (not shown) and drawers 200. The opposite sides of the drawers 200 are slidably connected to the cabinet via the slide rail device 100. During installation, the fixing seat 10 of the slide rail device 100 is fixed to the cabinet, and the slide rail devices 100 on the opposite sides of the drawers 200 are parallel and opposite to each other. The drawers 200 are mounted on the mounting seat 30 of the slide rail device 100. Specifically, each opposite side of the drawers 200 is provided with two insertion parts 210, and the two insertion parts 210 are spaced apart along the length direction of the movable rail 20. Each insertion part 210 extends downward from the bottom of the drawer 200. Two connectors 210 on one side of drawer 200 are respectively inserted into the mounting slot 21 and connecting slot 31 of one slide rail device 100, and two connectors 210 on the other side of drawer 200 are respectively inserted into the mounting slot 21 and connecting slot 31 of the other slide rail device 100, so that drawer 200 and slide rail device 100 can be detachably connected together, which facilitates the disassembly and assembly of drawer 200 and is conducive to subsequent maintenance and cleaning.
[0038] When multiple drawers 200 installed horizontally inside the refrigerator have inconsistent heights, loosen the locking screw 50 to release the mounting base 30. Then, insert a screwdriver into the screwdriver slot 45 of the rotating shaft 43. The screwdriver drives the rotating shaft 43 to rotate, which in turn drives the mounting base 30 and the drawers 200 installed on the mounting base 30 to rise and fall together until the multiple drawers 200 installed horizontally have the same height. After that, loosen the locking screw 50 again so that the screw head 51 of the locking screw 50 abuts against the mounting plate 32 of the mounting base 30 to clamp the mounting base 30 onto the movable rail 20, thereby locking the drawers 200 and the mounting base 30 at the desired height position.
[0039] The slide rail device 100 of the present invention connects the movable rail 20 and the mounting base 30 through the height adjustment member 40. After the slide rail device 100 is installed, the height of the mounting base 30 and the load mounted on the mounting base 30 can be adjusted by the height adjustment member 40 to ensure that multiple loads are at the same height in the horizontal direction.
[0040] The slide rail device 100 of the present invention drives the mounting base 30 to move vertically relative to the movable rail 20 by means of a rotating cam engaging with the mating part 25. It has a simple structure and is easy to adjust. By providing a locking screw 50, the mounting base 30 can be securely locked at the desired height position, preventing accidental sliding of the mounting base 30 relative to the movable rail 20.
[0041] It is understood that the structure of the height adjustment component 40 is not limited to this embodiment, and other height-adjustable structures in the prior art can also be used.
[0042] It is understood that the slide rail device 100 is not limited to the installation of refrigerator drawers, but can also be used on other devices that require sliding guidance.
[0043] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of the present invention, and all of these fall within the protection scope of the present invention.
