Description

Technical Field

[0001] This application relates to the field of slide rail technology, and in particular to a slide rail mechanism and a jewelry display case. Background Technology

[0002] Drawer slides are hardware connection components commonly used in furniture assembly to allow drawers or cabinet panels to move in and out. They are used to install sliding parts of furniture, such as drawers in storage cabinets, tabletops of dining tables, cabinet doors of wardrobes, and drawers in jewelry display cases, etc.

[0003] Traditional drawer slides lack internal cushioning devices, causing drawers or cabinet panels to collide with the cabinet body when pulled out or pushed in, resulting in abnormal noises and a poor user experience. To meet user needs, drawer slide mechanisms with cushioning devices have emerged on the market. However, the cushioning effect of current drawer slide mechanisms is not ideal, and their complex structure increases the time required to assemble the various components. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a slide rail mechanism and a jewelry display case, aiming to solve the problems of complex structure and poor buffering effect of current slide rail mechanisms.

[0005] In a first aspect, embodiments of this application provide a slide rail mechanism having a first direction, a second direction, and a third direction that are mutually perpendicular to each other, including: A slide rail extends along the first direction, and a slider is slidably connected to the slide rail; A buffer assembly includes a damper, a movable plate, and a limiting frame. The limiting frame is fixedly connected to one end of the slide rail and located on one side of the slide rail in the second direction. The limiting frame has a sliding cavity extending along the first direction. The movable plate is slidably fitted in the sliding cavity. The damper is fixed in the sliding cavity, and the piston rod of the damper extends along the first direction and is connected to the movable plate. A connecting plate is fixedly connected to the slider. The surface of the connecting plate facing the slide rail is provided with an abutment post extending along the third direction. The abutment post is located on the extension path of the sliding cavity in the first direction, so that when the slider slides along the first direction, the abutment post extends into the sliding cavity and abuts against the moving plate to push the moving plate to slide in the sliding cavity.

[0006] In one embodiment, the buffer assembly further includes a mounting bracket, which is fixed within the sliding cavity along the first direction. The movable plate is slidably connected to the mounting bracket, and the mounting bracket is further provided with a mounting cavity extending along the first direction. The damper is installed within the mounting cavity, and the piston rod of the damper passes through the mounting bracket and is connected to the movable plate.

[0007] In one embodiment, the buffer assembly further includes an elastic element disposed within the sliding cavity along the first direction, with one end of the elastic element connected to the end of the mounting bracket away from the movable plate, and the other end connected to the end of the movable plate away from the mounting bracket.

[0008] In one embodiment, the mounting bracket has an extension at one end away from the movable plate, the extension extending along the second direction, and the movable plate has a mounting portion at one end away from the mounting bracket, the mounting portion extending along the first direction. One end of the elastic member is engaged with the extension, and the other end is engaged with the mounting portion.

[0009] In one embodiment, the buffer assembly further includes a buffer disposed on the surface of the connecting plate facing the slide rail and located on the opposite side of the abutment post, and the buffer end of the buffer is arranged along the first direction for abutting against one end of the drawer extending into the cabinet body.

[0010] In one embodiment, the slide rail mechanism further includes at least two fixing plates, all of which are disposed on the side of the slide rail facing away from the slider in the third direction and are spaced apart along the first direction. The fixing plates are all fixedly connected to the slide rail, and the surface of the fixing plate facing away from the slide rail is used to connect with the bottom surface of the drawer. The limiting bracket is detachably connected to the surface of one of the fixing plates facing the slide rail.

[0011] In one embodiment, the slide rail is provided with a plurality of through holes spaced apart along the first direction, and the fixing plate is provided with fixing holes that cooperate with the through holes.

[0012] In one embodiment, the slide rail has a limiting post at one end away from the limiting frame. The limiting post extends along the third direction and abuts against the slider to prevent the slide rail from slipping off the slider.

[0013] Secondly, this application also provides a jewelry display case, comprising: The cabinet body has drawer slots; The drawers contain multiple storage compartments for jewelry; and... The slide rail mechanism described in the above embodiment is fixed to the bottom surface of the drawer, and the connecting plate of the slide rail mechanism is connected to the bottom surface of the drawer slot, so that the drawer can be pulled out and installed in the drawer slot.

[0014] In one embodiment, a pulley is fixedly connected to the bottom surface of the drawer, and when the drawer is inserted into the drawer slot, the wheel surface of the pulley makes rolling contact with the bottom surface of the drawer slot.

[0015] Compared with the prior art, the technical solutions provided in this application have the following advantages: A cleverly designed movable plate is slidably positioned within the sliding cavity, and the piston rod of the damper is connected to the movable plate. As the drawer is pushed back into its slot, the slide rail moves relative to the slider, while the damper and movable plate move closer to the connecting plate. Once the movable plate abuts against the abutment post on the connecting plate, a counterforce is applied, causing the movable plate to slide within the sliding cavity. This, in turn, pushes the piston rod of the damper to retract, generating a damping force within the damper that acts in the opposite direction on the movable plate. This reduces the speed at which the drawer is pushed back, achieving a gradual and smooth deceleration with excellent buffering effect. It fundamentally avoids rigid collisions with the cabinet and eliminates abnormal noise. Furthermore, the slide rail, damper, movable plate, and two limiting components are all directly mounted on the first mounting surface of the fixed plate, eliminating the need for complex spatial alignment, simplifying the structure, and significantly reducing assembly time.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. When an component is referred to as being "on" or "below" another component, the component can be located "directly" or "indirectly" on the other component, or there may be one or more intermediary components. The terms "first," "second," "third," etc., are only for the convenience of describing this technical solution and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first," "second," "third," etc., may explicitly or implicitly include one or more of that feature. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0020] In the following description, specific details such as particular system structures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art will understand that the present invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0021] The technical terms used in the embodiments of this application are explained and described below.

[0022] The terms "first direction X", "second direction Y", and "third direction Z" used in this application are defined to describe the positional relationship between components and can be specifically defined with a certain component as a reference. For clarity, this embodiment uses the first fixing plate 31 as a reference, and the first direction X is the length direction of the first fixing plate 31 (refer to...). Figure 4 The X direction is the first fixed plate 31, and the Y direction is the width direction (refer to the X direction). Figure 4 (Y direction in the middle), the third direction Z is the height direction of the first fixed plate 31 (refer to the Y direction), and the third direction Z is the height direction of the first fixed plate 31 (refer to the Y direction). Figure 4 (in the Z direction).

[0023] The damper 352 is specifically a hydraulic damper 352, which is filled with hydraulic oil. The piston rod is connected to the piston, and the piston has a small through hole. When the piston rod is pushed, the hydraulic oil needs to flow from one side to the other through the through hole. The throttling effect of the through hole generates a damping force. The faster the speed, the greater the resistance to oil flow and the stronger the damping force.

[0024] The slide rail mechanism 30 in this application embodiment can be applied to home furnishings (such as cabinets, wardrobe pull-out panels, TV cabinets, etc.), office equipment (such as file cabinet drawers, archive cabinet pull-out shelves, concealed keyboard trays), and luxury goods and cultural relics display (such as pull-out display stands, jewelry display drawers, etc.). The specific structure of the slide rail mechanism 30 in this application embodiment will be described in detail below using its application in a jewelry display case as an example.

[0025] Figure 1 This is a schematic diagram of a drawer in a jewelry display case in the pulled-out state according to this application; Figure 2 This is a schematic diagram from another perspective of a drawer in the extended position in a jewelry display case according to this application; Figure 3 This is a schematic diagram of a drawer in the pushed-back position of a jewelry display case according to this application. Please refer to... Figures 1 to 3This application also provides a jewelry display case, which includes a cabinet body 10, a drawer 20, and a slide rail mechanism 30. The cabinet body 10 has a drawer groove 10a, and the slide rail mechanism 30 is fixed to the bottom surface of the drawer 20. The connecting plate 34 of the slide rail mechanism 30 is connected to the bottom surface of the drawer groove 10a, so that the drawer 20 can be pulled out and installed in the drawer groove 10a. At this time, the slide rail mechanism 30 is concealed by the drawer 20. During the process of pulling out the drawer 20, the slide rail mechanism 30 is hidden between the drawer 20 and the cabinet body 10, which does not affect the aesthetic appearance of the jewelry display case. Furthermore, the slide rail mechanism 30 is installed on the bottom surface of the drawer groove 10a, which does not occupy the side space of the drawer groove 10a, and can maximize the lateral storage size of the drawer 20, which is conducive to improving space utilization. In addition, the drawer 20 has multiple storage compartments 20a inside for storing jewelry, which can be divided into sections according to the type and size of the jewelry. For example, small compartments can be used to store rings, long compartments can be used to store necklaces, and compartments with hooks can be used to store earrings, thus avoiding the chaos caused by mixing different jewelry and making it easy to locate and retrieve them quickly.

[0026] Figure 4 This is a schematic diagram illustrating the connection between the slide rail mechanism and the drawer in a jewelry display case according to this application. (Refer to...) Figure 4 The bottom surface of drawer 20 is fixedly connected with a pulley 40. When drawer 20 is inserted into drawer groove 10a, the wheel surface of pulley 40 rolls in contact with the bottom surface of drawer groove 10a, so that there is no jamming or jerking during the process of pushing and pulling drawer 20, ensuring that drawer 20 always slides smoothly along drawer groove 10a, improving the stability of operation and user experience.

[0027] Figure 5 This is a structural schematic diagram of a slide rail mechanism according to this application; Figure 6 This is a structural schematic diagram of a slide rail mechanism from another perspective according to this application. Please refer to... Figure 5 and Figure 6 Specifically, the slide rail mechanism 30 includes a connecting plate 34, a slide rail 32, and a buffer assembly 35. The slide rail 32 extends along the first direction X and is fixedly connected to the bottom surface of the drawer 20. A slider 33 is slidably connected to the slide rail 32, and the slider 33 is connected to the connecting plate 34, which is used to connect to the cabinet body 10. In other words, since the connecting plate 34 is fixed to the cabinet body 10 and connected to the slider 33, while the slide rail 32 is fixedly connected to the drawer 20, the slider 33 is restricted from moving when the drawer 20 is pulled out. Only the slide rail 32 moves relative to the slider 33 as the drawer 20 moves, thus providing a reference guide for the pulling out of the drawer 20, ensuring that the drawer 20 moves smoothly along a preset trajectory and avoiding deviation.

[0028] In addition, to prevent the slide rail 32 from slipping off the slider 33, a limiting post 38 is provided at the end of the slide rail 32 away from the drawer slot 10a. The limiting post 38 extends in the third direction and is used to abut against the slider, so that the limiting post 38 will restrict the slider 33 during the movement of the slide rail 32 relative to the slider 33, thereby preventing the slide rail 32 from slipping off.

[0029] Figure 7 This is a structural diagram of the moving plate, mounting bracket, and limiting bracket in a slide rail mechanism according to this application. Please refer to... Figure 7 The buffer assembly 35 includes a damper 352, a movable plate 351, and a limiting frame 353. The limiting frame 353 is fixedly connected to one end of the slide rail 32 and is located on one side of the slide rail 32 in the second direction Y. The limiting frame 353 has a sliding cavity A extending along the first direction X. The movable plate 351 is slidably fitted into the sliding cavity A. The damper 352 is fixed in the sliding cavity A, and the piston rod of the damper 352 extends along the first direction X and is connected to the movable plate 351. Meanwhile, in order to ensure that the movable plate 351 can slide in the sliding cavity A when the drawer 20 pushes back into the drawer slot 10a, an abutment post 37 extends along the third direction Z on the surface of the connecting plate 34 facing the slide rail 32. The abutment post 37 is located on the extension path of the sliding cavity A in the first direction X. In other words, during the process of the drawer 20 being pushed back into the drawer slot 10a, the limiting bracket 353, the moving plate 351, and the damper 352 move together with the drawer 20, so that the moving plate 351 continuously approaches the connecting plate 34. Since the limiting post 38 is located on the extension path of the sliding cavity A in the first direction X, the abutting post 37 can abut against the moving plate 351. When the moving plate 351 abuts against the abutting post 37, the moving plate 351 is pushed by the abutting post 37 to slide in the sliding cavity A. At this time, the piston rod of the damper 352 is squeezed by the moving plate 351 and contracts, thereby reducing the speed at which the drawer 20 is pushed back and achieving a buffering effect.

[0030] To facilitate understanding of the buffering principle of the buffer component 35 during the pulling out and pushing back of the drawer 20, the following explanation uses the pulling out and pushing back processes of the drawer 20 as examples: Drawer pull-out process: During the process of pulling the drawer 20 outward, the slide rail 32 moves relative to the slider 33, causing the damper 352 and the moving plate 351 to move away from the connecting plate 34 along with the movement of the drawer 20, allowing the moving plate 351 to disengage from the contact post 37, so that the force exerted by the moving plate 351 on the damper 352 disappears. At this time, since the piston rod of the damper 352 is in a compressed state, the piston rod of the damper 352 pushes the moving plate 351 to slide in the sliding cavity A until the piston rod of the damper 352 returns to its natural extension state, and the drawer 20 is in the pulled-out state.

[0031] Drawer push-back process: During the process of pushing drawer 20 inward back into drawer slot 10a, slide rail 32 moves relative to slider 33, causing damper 352 and moving plate 351 to move closer to connecting plate 34 as drawer 20 moves. After moving plate 351 contacts abutting post 37 on connecting plate 34, as drawer 20 continues to be pushed back, the abutting post 37 blocks moving plate 351, causing abutting post 37 to exert a reverse force on moving plate 351, thereby driving moving plate 351 to slide outward in the sliding cavity A along the first direction X, pushing the piston rod of damper 352 to retract, causing the medium inside damper 352 to generate damping force to act in the opposite direction on moving plate 351, thereby reducing the speed at which drawer 20 is pushed back, preventing drawer 20 from directly impacting cabinet 10 due to inertia, achieving soft closure, reducing impact noise and wear of components.

[0032] As can be seen, the slide rail mechanism 30 of this embodiment cleverly arranges a movable plate 351 slidably in the sliding cavity A, and connects the piston rod of the damper 352 to the movable plate 351. So that when the drawer 20 is pushed back into the drawer slot 10a, the slide rail 32 moves relative to the slider 33, and the damper 352 and the movable plate 351 move closer and closer to the connecting plate 34 as the drawer 20 moves. After the movable plate 351 abuts against the abutting post 37 on the connecting plate 34, the movable plate 351 is subjected to a reverse force and slides in the sliding cavity A, thereby pushing the piston rod of the damper 352 to retract. This causes the medium inside the damper 352 to generate a damping force to act in the opposite direction on the movable plate 351, thereby reducing the speed at which the drawer 20 is pushed back, achieving a gradual and smooth deceleration, with a good buffering effect, which can fundamentally avoid rigid collisions with the cabinet 10 and eliminate abnormal noise.

[0033] Please continue to refer to Figure 7 and Figure 8 In one embodiment, the buffer assembly 35 further includes a mounting bracket 354, which is fixed in the sliding cavity A along the first direction X. The movable plate 351 is slidably connected to the mounting bracket 354 so that when the abutment post 37 pushes the movable plate 351 to compress the piston rod or the piston rod pushes the movable plate 351 to slide, the mounting bracket 354 can provide a reference for the movable plate 351 to slide along the first direction X, and cooperate with the cavity wall of the sliding cavity A to limit the offset of the movable plate 351 in the second direction Y, thereby forming a double constraint to control the sliding deviation of the movable plate 351 within a preset range, avoiding sudden changes in damping force caused by the shaking of the movable plate 351, and ensuring a smoother buffering process.

[0034] In practical applications, in order to ensure good damping effect, it is necessary to ensure that the damper 352 does not move relative to the fixed plate 31. Figure 8This is a schematic diagram of the damper and mounting bracket in a slide rail mechanism according to this application. Therefore, in this embodiment, the mounting bracket 354 is further provided with a mounting cavity 354c extending along the first direction X. The damper 352 is installed in the mounting cavity 354c, and the piston rod of the damper 352 passes through the mounting bracket 354 and is connected to the moving plate 351. In other words, by opening a mounting cavity 354c on the mounting bracket 354, the damper 352 can be precisely positioned along the first direction X. Furthermore, the inner wall of the mounting cavity 354c constrains the damper 352 to prevent it from loosening or shifting in angle due to vibration during frequent buffering (such as the drawer 20 being repeatedly pushed back and forth). Compared to the existing buffering device where the damper 352 is directly fixed to the fixed plate 31 with fasteners (such as bolts), this method is simple to install and remove, and facilitates the maintenance or replacement of the damper 352 in the future. At the same time, it can also ensure that the piston rod of the damper 352 always extends and retracts along the first direction X, and the direction of the damping force is completely consistent with the movement direction of the moving plate 351 and the connecting plate 34. This avoids buffering force loss or local stress concentration caused by deviation in the direction of the force, thereby significantly improving the stability of the buffering effect.

[0035] Please refer to Figure 7 Furthermore, the mounting bracket 354 has an abutment portion 354a at the end away from the moving plate in the first direction X. When the mounting bracket 354 is inserted into the sliding cavity A, the abutment portion 354a abuts against the end face of the limiting bracket 353, so that the mounting bracket 354 is detachably connected to the limiting bracket 353. That is to say, during assembly, the end of the mounting bracket 354 without the abutment portion 354a can be inserted into the sliding cavity A from one end of the limiting bracket 353. As the mounting bracket 354 is continuously inserted, the abutment portion 354a continuously approaches the end face of the limiting bracket 353 until the abutment portion 354a abuts against the end face of the limiting bracket 353, thus enabling the mounting bracket 354 to be detachably connected to the limiting bracket 353. When the damper 352 or the moving plate 351 in the buffer assembly 35 is worn or malfunctions, simply pull the mounting bracket 354 out of the sliding cavity A, and then remove the damper 352, the moving plate 351 and the auxiliary parts separately. There is no need to disassemble the entire slide rail mechanism 30 (such as the slide rail 32, the slider 33, and the fixed plate 31), which greatly simplifies the maintenance process.

[0036] In one embodiment, the buffer assembly 35 further includes an elastic element 355, which passes through the sliding cavity A along the first direction X. One end of the elastic element 355 is connected to the end of the mounting bracket 354 away from the moving plate 351, and the other end is connected to the end of the moving plate 351 away from the mounting bracket 354. It should be noted that the elastic element 355 can specifically be a spring, but is not limited to this.

[0037] In other words, after the drawer 20 is pushed back into the drawer slot 10a, the elastic element 355 is compressed by the moving plate 351 and stores energy. When the drawer 20 is pulled outward, the elastic element 355 exerts an inward force on the moving plate 351 due to its own elasticity, causing the moving plate 351 to move inward, thereby pulling the piston rod of the damper 352 back to its natural extension state in order to prepare for the next buffering.

[0038] Specifically, the mounting bracket 354 has an extension 354b at one end away from the movable plate, the extension extending along the second direction Y. The movable plate 351 has a mounting part 351a on the outer side of one end away from the mounting bracket 354, the mounting part 351a extending along the third direction Z. One end of the elastic member 355 is engaged with the extension 354b, and the other end is engaged with the mounting part 351a.

[0039] In one embodiment, a buffer 39 is also included. The buffer is disposed on the surface of the connecting plate 34 facing the slide rail 32 and located on the opposite side of the abutment post 37. The buffer end of the buffer 39 is arranged along the first direction X and is used to abut against the end of the drawer 20 that extends into the cabinet 10. That is, when the drawer 20 is pushed into the cabinet 10 to a near-closed position, the buffer end of the buffer 39 will first contact the end of the drawer 20. Through its own deformation (such as elastic extension, hydraulic damping, etc.), it absorbs the kinetic energy when the drawer is closed, which can greatly reduce or even eliminate the collision impact noise, solve the problem of abnormal noise when closing traditional drawers, and improve the quietness of the use environment.

[0040] In one embodiment, the slide rail mechanism 30 further includes at least two fixing plates. All fixing plates are located on the side of the slide rail facing away from the slider 33 in the third direction Z and are spaced apart along the first direction X. The fixing plates are all fixedly connected to the slide rail 32, and the surface of the fixing plate facing away from the slide rail 32 is used to be fixedly connected to the bottom surface of the drawer 20. The limiting bracket 353 is detachably connected to the surface of one of the fixing plates facing the slide rail 32.

[0041] It should be noted that the "at least two" mentioned above refers to two or more, depending on the required length of the slide rail. To save costs and ensure installation efficiency, two fixing plates are used in practical applications. For ease of description, they are referred to as the first fixing plate 31 and the second fixing plate 36. The first fixing plate 31 and the second fixing plate 36 are fixedly connected to the slide rail 32 at intervals along the first direction X. Then, the surfaces of the first fixing plate 31 and the second fixing plate 36 facing away from the slide rail 32 are fixedly connected to the bottom surface of the drawer 20, thus completing the quick installation of the entire slide rail mechanism 30 and the drawer 20. This allows for the installation of slide rails 32 of various lengths onto corresponding drawers 20. Compared to using a single fixing plate, this method offers wider adaptability and eliminates the need to replace the fixing plate for different slide rail lengths, thus saving costs.

[0042] Furthermore, the fixing plate and the slide rail 32 are connected in a detachable manner. Specifically, multiple through holes are spaced apart along the first direction X on the slide rail, and fixing holes that mate with the through holes are provided on the fixing plate. When fixing, the fixing plate and the slide rail 32 are pressed together, and the fixing holes and through holes are aligned. Then, fasteners (such as bolts) are passed through the fixing holes and through holes in sequence and locked, thus completing the detachable connection between the fixing plate and the slide rail. The structure is simple and easy to assemble and disassemble.

[0043] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
