Description

Technical Field

[0001] This utility model relates to the field of slide rail technology, and in particular to a concealed three-section synchronous slide rail. Background Technology

[0002] Concealed three-section synchronous drawer slides are widely used in various furniture and cabinets, especially drawers that require frequent opening and closing and bear heavy loads, such as kitchen cabinets, office furniture, wardrobes, etc. Concealed three-section synchronous drawer slides can provide excellent performance and convenient user experience.

[0003] Concealed three-section synchronous slide rails have become an indispensable component in modern furniture and cabinets due to their aesthetic appeal, strong load-bearing capacity, smoothness, good cushioning effect, and convenient installation and adjustment.

[0004] Chinese Patent Publication No. CN208870928U discloses a three-section synchronous slide rail, which has a simple structure, is easy to install and replace, and has a longer service life. The technical solution is as follows: A three-section synchronous slide rail includes two sets of slide rail assemblies, each with a synchronization component mounted on it. Each slide rail assembly includes a fixed rail, a middle rail, and a sliding rail. Each synchronization component includes a flexible deflector and a roller mounted on the middle rail. The flexible deflector is connected to both the fixed rail and the sliding rail. A rope base is also connected to the middle rail, allowing the rope base to rotate. One end of the flexible deflector is wrapped around one end of the rope base and fixed thereto. The other end of the flexible deflector passes around the roller and is wrapped in the opposite direction around the other end of the rope base, with that end also fixed thereto. A connecting rod connects the rope bases of the two sets of slide rail assemblies.

[0005] During operation, the fixed rail and the sliding rail move in opposite directions, not the same direction. With this type of sliding rail structure, a lot of space is required for the drawer to slide out. However, drawers usually provide limited installation space for the sliding rail structure, so the above-mentioned device has limitations in practical use. Utility Model Content

[0006] The main purpose of this utility model is to provide a concealed three-section synchronous slide rail, which can effectively solve the problem that the different sliding directions of the three-section slide rail are not the same, which makes this slide rail structure limited in practical use.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A concealed three-section synchronous slide rail includes a rectangular plate. A mounting plate is fixedly connected to the left end of the rectangular plate. A slide rail one is fixedly connected to the upper right part of the rectangular plate. A driven component is provided on the inner surface of the slide rail one. A slide rail two is slidably connected to the outer surface of the slide rail one. A slide rail component is provided on the outer surface of the slide rail two. A sliding component is provided on the upper right part of the rectangular plate.

[0009] Preferably, the sliding component includes a vertical plate, which is fixedly connected to the upper right side of the rectangular plate, and a limit component and a sliding component are provided on the upper right side of the vertical plate.

[0010] Preferably, the limiting component includes a slider, a groove is provided on the upper right end of the upright plate, and steel balls are rotatably connected to the upper and lower inner surfaces of the slider, with the two steel balls slidably connected to the inner surface of the groove.

[0011] Preferably, the sliding assembly includes a second slider, a second groove is provided on the upper right end of the upright plate, and steel balls are rotatably connected to the inner surfaces of the upper and lower sides of the second slider. The two steel balls are slidably connected to the inner surface of the second groove, and the second slider is fixedly connected to the middle of the left end of the second slide rail.

[0012] Preferably, the slide rail assembly includes a slide rail three, which is slidably connected to the outer surface of the slide rail two, the slider one is fixedly connected to the front left end of the slide rail three, and the lower left and right ends of the slide rail three are symmetrically fixedly connected with racks.

[0013] Preferably, the driven component includes a second round rod, which is rotatably connected to the left and right sides of the front side of the inner surface of the first slide rail. The first round rod is rotatably connected to the rear left end of the first slide rail and extends to the rear right end. A gear is symmetrically fixedly connected to the left and right sides of the outer surface of the first round rod. The rack on the same side meshes with the gear. A moving component is provided on the outer surface of the first round rod and the outer surface of the second round rod.

[0014] Preferably, the moving component includes two gears, which are fixedly connected to the middle of the outer surface of the first round rod and the middle of the outer surface of the second round rod, respectively. An inner toothed belt is sleeved on the outer surface of the two gears, and a block is fixedly connected to the front of the upper end of the inner toothed belt. A block is fixedly connected to the middle of the upper side of the inner surface of the second slide rail.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention is equipped with a driven component, which can drive the slide rail three to move outward and inward when the drawer slides outward and inward. The movement of the slide rail three in and out of the cabinet drives the driven component, which in turn drives the slide rail two to move outward and inward. This achieves synchronous movement of the slide rail three and the slide rail two, so that the movement trajectories of the slide rail three and the slide rail two are the same, making the opening and closing process of the drawer smoother.

[0017] 2. The steel balls 1 and 2 provided in this utility model reduce the friction when slider 1 and slider 2 slide in slide groove 1 and slide groove 2 respectively, thus making the sliding process of slider 1 and slider 2 smoother, and thus making the sliding process of slide rail 3 and slide rail 2 smoother; the slider 2 provided allows the rack to drive slider 2 to move from back to front in the slide groove when slide rail 3 moves a certain distance into the cabinet, thus making slide rail 2 slide automatically into the cabinet.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figure 1 and Figure 2 As shown, a concealed three-section synchronous slide rail includes a rectangular plate 1, a mounting plate 2 fixedly connected to the left end of the rectangular plate 1, a slide rail 3 fixedly connected to the upper right side of the rectangular plate 1, a driven component 4 provided on the inner surface of the slide rail 3, a slide rail 5 slidably connected to the outer surface of the slide rail 3, a slide rail component 6 provided on the outer surface of the slide rail 5, and a sliding component 7 provided on the upper right side of the rectangular plate 1.

[0028] Two of these devices are grouped together; this plan only demonstrates and describes the structure and implementation process of one device.

[0029] In practice, the two devices are fixed on the left and right sides of the cabinet where the drawers need to be installed, and the two slide rail assemblies 6 are installed on the lower left and right sides of the drawers, thus completing the installation of the device.

[0030] When the user pulls the drawer out of the cabinet, the slide rail assembly 6 will first move out of the cabinet. When the slide rail assembly 6 moves out of the cabinet, it will drive the driven assembly 4. When the slide rail assembly 6 has moved half the length from inside the cabinet to outside, the driven assembly 4 will drive the slide rail 5 to move from inside the cabinet to outside.

[0031] After the slide rail assembly 6 is completely moved out of the cabinet, slide rail 2 5 will also move a distance outward from the cabinet.

[0032] Conversely, when the slide rail assembly 6 is moved into the cabinet, it will also drive the driven assembly 4 to run. When the slide rail assembly 6 has moved halfway into the cabinet, the continued movement of the slide rail assembly 6 into the cabinet will drive the slide rail 2 5 to move into the cabinet as well, until the slide rail 2 5 and the slide rail assembly 6 are both moved back into the cabinet.

[0033] The presence of sliding component 7 limits the movement of slide rail 2 5 and slide rail component 6 inside and outside the cabinet, while making the movement of slide rail 2 5 and slide rail component 6 smoother.

[0034] Specifically, to achieve synchronized movement between the slide rails, thus making the drawer open and close more smoothly, please refer to... Figure 3 The sliding component 7 includes a vertical plate 71, which is fixedly connected to the upper right part of the rectangular plate 1. A limit component 72 and a sliding component 73 are provided on the upper right part of the vertical plate 71.

[0035] Further reading Figure 4The limiting component 72 includes a slider 722. A groove 721 is provided on the upper right side of the upright plate 71. Steel balls 723 are rotatably connected to the upper and lower inner surfaces of the slider 722. The two steel balls 723 are slidably connected to the inner surface of the groove 721. The sliding component 73 includes a slider 732. A groove 731 is provided on the upper right side of the upright plate 71. Steel balls 733 are rotatably connected to the upper and lower inner surfaces of the slider 732. The two steel balls 733 are slidably connected to the inner surface of the groove 731. The slider 732 is fixedly connected to the middle of the left end of the slide rail 5.

[0036] Further reading Figure 5 The slide rail assembly 6 includes a slide rail 3 61, which is slidably connected to the outer surface of the slide rail 2 5. The slider 1 722 is fixedly connected to the front left end of the slide rail 3 61. The lower left and right ends of the slide rail 3 61 are symmetrically fixedly connected with racks 62.

[0037] Further reading Figure 6 The driven component 4 includes a second round rod 43, which is rotatably connected to the left and right sides of the front side of the inner surface of the first slide rail 3. The left rear end of the first slide rail 3 is rotatably connected to a first round rod 41, and the left and right rear ends of the first round rod 41 are symmetrically fixedly connected to gears 42. The rack 62 on the same side meshes with gears 42. The outer surface of the first round rod 41 and the outer surface of the second round rod 43 are both provided with a moving component 44.

[0038] Further reading Figure 7 The moving component 44 includes two gears 441, which are fixedly connected to the middle of the outer surface of the first round rod 41 and the middle of the outer surface of the second round rod 43, respectively. The outer surfaces of the two gears 441 are jointly fitted with an inner toothed belt 442. A block 443 is fixedly connected to the front of the upper end of the inner toothed belt 442, and a block 444 is fixedly connected to the middle of the upper side of the inner surface of the slide rail 5.

[0039] The sliding connection between slide rail 2 5 and slide rail 1 3, and the sliding connection between slide rail 3 61 and slide rail 2 5 mentioned above are conventional designs in the prior art. The structure and working principle of these designs will not be elaborated further in this solution.

[0040] The rotational connection between the two steel balls 733 and the slider 732, and the rotational connection between the two steel balls 723 and the slider 722, can realize the multi-directional rolling of the two steel balls 723 in the mounting groove of the slider 722 and the two steel balls 733 in the mounting groove of the slider 732. This is a mature technical means in the prior art, and its structure and working principle will not be elaborated further in this solution.

[0041] The aforementioned internal toothed belt 442 meshes with the two gears 441, simultaneously satisfying the wrap angle requirement;

[0042] In practice, after the device is installed on the drawer, when the drawer is moved from inside the cabinet to outside, the slide rail 61 will move from inside the cabinet to outside. During this process, the two racks 62 will also move from inside the cabinet to outside, thereby causing the two gears 42 to rotate counterclockwise.

[0043] Both gears 42 rotate counterclockwise, causing the round rod 41 to rotate counterclockwise, which in turn causes the gear 441, which is fixedly connected to the round rod 41, to rotate. This causes the internal gear belt 442 to rotate back and forth, which in turn causes the block 443 to move continuously from the front to the back from the frontmost position. During this process, the reciprocating rotation of the internal gear belt 442 also causes the gear 441, which is fixedly connected to the round rod 43, to rotate, thus ensuring the stability of the entire process.

[0044] During the above process, slide rail 2 5 will not slide. When slide rail 3 61 moves about half a length out of the cabinet, block 1 443 will move to a position where it abuts against block 2 444. At this time, if slide rail 3 61 continues to move out of the cabinet, the internal toothed belt 442 will rotate back and forth, thereby driving block 1 443 to move from front to back, thereby driving block 2 444 to move from front to back, thereby driving slide rail 2 5 to start sliding from inside the cabinet to outside the cabinet. In this way, slide rail 3 61 and slide rail 2 5 can move synchronously, so that slide rail 3 61 and slide rail 2 5 have the same movement trajectory, thereby making the opening and closing process of the drawer smoother.

[0045] When slide rail 3 61 continues to move out of the cabinet, it will drive slider 1 722 to move continuously from the front to the back in slide groove 1 721. When slide rail 2 5 starts to move continuously out of the cabinet, it will drive slider 2 732 to move continuously from the front to the back in the middle position in slide groove 2 731.

[0046] During this movement, the two steel balls 723 and 733 make the friction of slider 722 and slider 732 sliding in groove 721 and groove 731 respectively less, thus making the sliding process of slider 722 and slider 732 smoother, and thus making the sliding process of slide rail 61 and slide rail 25 smoother.

[0047] When slider 1 722 moves to the rearmost side within slide groove 1 721, slide groove 1 721 limits the movement of slider 1 722. At this time, slide rail 3 61 cannot move out of the cabinet. At the same time, slider 2 732 also moves to the rear position within slide groove 2 731. Under the action of slide groove 2 731, slide rail 2 5 also cannot move out of the rear cabinet. At this time, both block 1 443 and block 2 444 move from the front to the rear position.

[0048] Conversely, when the drawer is moved from the outside to the inside of the cabinet, the slide rail 3 61 will move from the outside to the inside of the cabinet. During this process, the two racks 62 will also move from the outside to the inside of the cabinet, thereby causing the two gears 42 to rotate clockwise.

[0049] Both gears 42 rotate clockwise, and under the same working principle, the internal gear belt 442 reciprocates, thereby driving the block 443 to move continuously from the rear to the front from the rearmost position.

[0050] At this time, slide rail 2 5 will not slide. When slide rail 3 61 continues to move about half a length into the cabinet, slide rail 3 61 on the left side will move to the position where it abuts against slide rail 2 732. At this time, if slide rail 3 61 continues to slide into the cabinet, it will cause slide rail 2 5 to start sliding from outside the cabinet into the cabinet.

[0051] When slider 722 moves from the rearmost side to the frontmost side within slide groove 721, slide groove 721 also limits the movement of slider 722. At this time, slide rail 61 cannot move into the cabinet. Meanwhile, slider 732 moves to the middle position within slide groove 731, thus completing the operation of sliding the drawer back into the cabinet.

[0052] The working principle of this utility model is as follows:

[0053] Fix the two devices to the left and right sides of the cabinet where the drawers are to be installed, and install the two devices at the bottom left and right sides of the drawers respectively.

[0054] When the drawer is pulled out of the cabinet, the slide rail 61 moves from inside the cabinet to outside, and the two racks 62 also move from inside the cabinet to outside, thereby causing the two gears 42 to rotate counterclockwise, which in turn causes the round rod 41 to rotate counterclockwise, which in turn causes the gear 441 to rotate, which in turn causes the internal gear belt 442 to rotate back and forth, which in turn causes the block 443 to move continuously from front to back.

[0055] When slide rail 3 61 moves about halfway out of the cabinet, block 1 443 will come into contact with block 2 444. As slide rail 3 61 continues to move out of the cabinet, block 1 443 will move from front to back, causing block 2 444 to move from front to back. This will cause slide rail 2 5 to start sliding from inside the cabinet to outside the cabinet until slide rail 3 61 is completely moved out of the cabinet.

[0056] When the drawer is moved from the outside to the inside of the cabinet, the slide rail 61 will move from the outside to the inside of the cabinet. During this process, the two racks 62 will also move from the outside to the inside of the cabinet, thereby causing the two gears 42 to rotate clockwise. Under the same working principle, the internal gear belt 442 will rotate back and forth, thereby causing the block 443 to move continuously from the back to the front from the rearmost position.

[0057] When slide rail 3 61 moves about halfway into the cabinet, slide rail 3 61 on the left side will come into contact with slider 2 732. As slide rail 3 61 continues to slide into the cabinet, it will cause slide rail 2 5 to start sliding from outside the cabinet into the cabinet until slide rail 3 61 is completely moved into the cabinet.

[0058] 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.
