Description

Technical Field

[0001] This utility model relates to the field of guide rail technology, specifically a bidirectional disassembly mechanism for heavy-duty steel ball guide rails. Background Technology

[0002] Ball bearing guides, due to their high load-bearing capacity and smooth sliding, are widely used in server rack drawers, sliding parts of industrial equipment, and furniture pull-out structures. For easy installation, maintenance, or replacement, the inner rail of the guide needs to be easily detachable from its mating middle or outer rail. Commercially available inner rail disassembly mechanisms often include a lever for disassembly. Users release the barrier between the middle and inner rails by moving the lever or pressing down on a clip, allowing the inner rail to be removed. Guide rails are used in pairs, and their unlocking mechanisms often operate in opposite or mirror-symmetrical directions. This requires users to first distinguish between the left and right rails when disassembling the inner rail. When users are unfamiliar with the guide rail design, or operate in poor lighting or confined spaces, confusion is easily caused, requiring repeated attempts at different operating directions. This not only wastes time and reduces disassembly efficiency but may also damage the guide rail itself due to improper operation or applying excessive force in the wrong direction. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of existing technologies and provide a heavy-duty steel ball guide rail bidirectional disassembly mechanism that is simple in structure, low in manufacturing cost, has no directional restriction on unlocking operation, can improve disassembly efficiency, extend service life, has reliable and stable drive, and has a wide range of applications.

[0004] The purpose of this utility model is achieved by the following method: a heavy-duty steel ball guide rail bidirectional disassembly mechanism, comprising an outer rail, a middle rail and an inner rail sequentially mounted from the outside to the inside, wherein an anti-disengagement buckle is provided between the inner rail and the middle rail, and the anti-disengagement buckle is hooked to the middle rail to prevent the inner rail from detaching from the middle rail; a locking mechanism is also provided on the inner rail, the locking mechanism comprising a locking plate and a driving plate; the inner end of the locking plate is engaged with the anti-disengagement buckle to push the anti-disengagement buckle to move, and the other end of the locking plate is connected to the driving plate;

[0005] It also includes a wrench hinged to the outer end of the inner rail. The wrench has an upper drive column and a lower drive column protruding on both sides. Correspondingly, the drive plate has an upper drive groove and a lower drive groove through it. The upper drive column is slidably installed in the upper drive groove, and the lower drive column is slidably installed in the lower drive groove.

[0006] The outer end of the inner rail is provided with a first hinge hole, and the wrench is provided with a second hinge hole. The hinge shaft passes through the second hinge hole and connects to the first hinge hole, and the wrench swings along the hinge shaft.

[0007] The outer end of the drive plate is provided with a guide groove, which is fitted onto the outside of the hinge shaft.

[0008] The guide groove is a horizontally extending waist-shaped groove.

[0009] The upper and lower drive slots are symmetrically distributed arc slots.

[0010] The wrench is fitted with a protective cover on its outer surface.

[0011] The anti-disengagement swing hinge is installed on the inner rail. The anti-disengagement hook has a buckle groove on the side facing the drive plate. Correspondingly, the locking plate has a buckle hook that goes into the buckle groove. When the locking plate moves, the anti-disengagement hook is driven to swing through the buckle groove.

[0012] A reset torsion spring is provided between the anti-disengagement buckle and the inner cabinet, which drives the anti-disengagement buckle to swing towards the buckle platform.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings. A heavy-duty steel ball guide rail bidirectional disassembly mechanism includes an outer rail 1, a middle rail 2, and an inner rail 3, which are sequentially mounted from the outside to the inside. An anti-disengagement buckle 4 is provided between the inner rail 3 and the middle rail 2. The anti-disengagement buckle 4 is hooked to the middle rail 2 to prevent the inner rail 3 from disengaging from the middle rail 2. A locking mechanism 5 is also provided on the inner rail 3. The locking mechanism 5 includes a locking plate 51 and a driving plate 52. The inner end of the locking plate 51 is engaged with the anti-disengagement buckle 4 to push the anti-disengagement buckle 4 to move. The other end of the locking plate 51 is connected to the driving plate 52.

[0024] It also includes a wrench 53 hinged to the outer end of the inner rail 3. The wrench 53 has an upper drive column 61 and a lower drive column 62 protruding on both sides. Correspondingly, the drive plate 52 has an upper drive groove 71 and a lower drive groove 72 through it. The upper drive column 61 is slidably installed in the upper drive groove 71, and the lower drive column 62 is slidably installed in the lower drive groove 72.

[0025] like Figure 1-3 As shown. The guide rail structure in this case is a three-section guide rail, including an outer rail, a middle rail, and an inner rail. The inner rail slides along the middle rail until the anti-disengagement buckle engages with the middle rail, locking the inner rail within the middle rail and preventing it from slipping off. A locking mechanism is provided on the inner rail to drive the anti-disengagement buckle. The locking mechanism includes a locking plate, a drive plate, and a wrench hinged to the outer end of the inner rail. The inner end of the locking plate engages with the anti-disengagement buckle, while the other end of the locking plate is connected to the drive plate, and the wrench is connected to the outer end of the drive plate.

[0026] When the user swings the wrench upwards around its hinge point, the lower drive column presses against the inner wall of the outer end of the lower drive groove, pushing the drive plate outwards. Simultaneously, the upper drive column slides along the upper drive groove. Conversely, when the user swings the wrench downwards around its hinge point, the upper drive column presses against the inner wall of the outer end of the upper drive groove, pushing the drive plate outwards. Simultaneously, the lower drive column slides along the lower drive groove.

[0027] Therefore, through the ingenious cooperation between the upper drive column and the upper drive groove, and the lower drive column and the lower drive groove, whether the user pulls the wrench up or down, one of the drive columns will press against the inner wall of the corresponding drive groove to push it, while the other drive column will slide in the corresponding drive groove, driving the drive plate to pull outward, and simultaneously driving the locking plate to move. The movement of the locking plate will push the anti-disengagement latch to release the hook state with the middle rail, no longer restricting the locking of the inner rail. At this time, the inner rail can be easily pulled out from the middle rail, so that the structure and operation of the wrench no longer distinguish between the left guide rail and the right guide rail, realizing that the locking mechanism can be driven by a single wrench whether it is moving up or down.

[0028] The outer end of the inner rail 3 is provided with a first hinge hole 31, and the wrench 53 is provided with a second hinge hole 531. The hinge shaft passes through the second hinge hole 531 and connects to the first hinge hole 31. The wrench 53 swings along the hinge shaft.

[0029] like Figure 4-5 As shown. To further limit the swing trajectory and connection method of the wrench, a first hinge hole is provided at the inner rail end, and a second hinge hole is provided at the wrench end. A hinge shaft passes through the second hinge hole and connects to the first hinge hole, limiting the wrench to swing only along this hinge shaft and ensuring the stability of the wrench during swing. Secondly, the hinge connection method is a common and effective way to achieve lever operation. It has a simple structure, low manufacturing cost, and requires only a small amount of force from the user to drive the locking mechanism.

[0030] The outer end of the drive plate 52 is provided with a guide groove 521, which is fitted onto the hinge shaft.

[0031] like Figure 4-6 As shown, a guide groove is provided to guide the movement of the drive plate, and the guide groove is fitted with a hinge shaft. By using the existing hinge shaft as a guide element, no additional parts are needed for the guiding operation, simplifying the structure and making it compact.

[0032] When the wrench swings and pushes the drive plate to move, it forces the drive plate to move along the hinge axis in the guide groove, providing a stable guide environment for the movement of the drive plate, preventing the drive plate from shaking or deviating when under force, ensuring that the movement trajectory of the drive plate is accurate, and the pushing force can be accurately transmitted to the locking plate.

[0033] The guide groove 521 is a horizontally extending waist-shaped groove.

[0034] like Figure 4-6 As shown, the guide groove is designed as a horizontally extending waist-shaped groove. The shape of the waist-shaped groove allows the hinge shaft to slide relatively within the groove, while also restricting and constraining the direction and range of motion of the drive plate. The waist-shaped groove can better ensure the linear motion stroke of the drive plate and ensure the smooth movement of the drive plate.

[0035] The upper drive groove 71 and the lower drive groove 72 are symmetrically distributed arc grooves.

[0036] like Figure 6 As shown, the upper and lower drive slots are symmetrically distributed arc-shaped grooves. Due to their arc-shaped and symmetrical design, the drive column can slide within the corresponding drive slot regardless of whether the user pulls the wrench up or down. The rotational motion of the wrench is converted into the translational motion of the drive plate, thereby driving the locking plate and anti-disengagement mechanism. The symmetrical arc-shaped grooves ensure that the wrench operates in two opposite directions, producing the same driving effect, thus unlocking the inner rail. Users do not need to distinguish between the left and right guide rails, greatly simplifying the disassembly operation, improving convenience, and enhancing the user experience. Furthermore, the arc-shaped grooves improve the smooth sliding of the drive column within the grooves, reducing the possibility of jamming.

[0037] The outer surface of the wrench 53 is fitted with a protective cover 8.

[0038] like Figure 3-4 As shown, a protective cover is fitted onto the outer surface of the wrench. Conventional protective covers are made of rubber or plastic, providing a non-slip surface and offering some protection to the wrench body from impacts or wear. Furthermore, this provides a better feel for the user, reducing hand discomfort caused by prolonged or frequent use, and enhancing the overall aesthetics of the product.

[0039] The anti-disengagement buckle 4 is mounted on the inner rail 3 in a swing hinge manner. The anti-disengagement buckle 4 has a buckle groove 41 on the side facing the drive plate 52. Correspondingly, the locking plate 51 has a buckle platform 511 that hooks into the buckle groove 41. When the locking plate 51 moves, it drives the anti-disengagement buckle 4 to swing through the buckle groove 41.

[0040] like Figure 3 , 5 As shown, the anti-disengagement buckle is hinged and swing-mounted on the inner rail. Its body has a latching groove, while the locking plate has a latching platform. The latching platform and the latching groove engage to lock the connection between the anti-disengagement buckle and the locking plate. When the drive plate moves, it synchronously drives the locking plate. The latching platform acts directly on the latching groove, driving the anti-disengagement buckle to swing around its hinge point, releasing the latch from the middle rail. This direct drive method effectively acts on the anti-disengagement buckle, resulting in more efficient and stable driving force, ensuring the anti-disengagement buckle is effectively driven, thus achieving the unlocking purpose.

[0041] A reset torsion spring 9 is provided between the anti-disengagement buckle 4 and the inner cabinet, driving the anti-disengagement buckle 4 to swing towards the buckle platform 511.

[0042] like Figure 4As shown: In this case, a reset torsion spring is installed. This ensures that even without external force or wrench operation, the reset torsion spring continuously applies a swinging force to the anti-disengagement clip, pushing it to swing towards the locking platform. This ensures the anti-disengagement clip automatically remains in the locked position, guaranteeing the normal and safe use of the guide rail. Users only need to disassemble and unlock the clip; manual reset is unnecessary. Releasing the wrench automatically locks it. Furthermore, the reset torsion spring enhances the connection strength of the anti-disengagement clip, effectively preventing accidental unlocking due to external vibrations, thus ensuring high safety.

[0043] In summary, when the user needs to disassemble the inner rail, they can move the wrench up or down, causing the drive pin of the wrench to slide along the corresponding drive groove. It should be noted that there are two drive pins: an upper drive pin and a lower drive pin. Correspondingly, there are two drive grooves: an upper drive groove and a lower drive groove. Whether the user moves the wrench up or down, one drive pin will press against the inner wall of the corresponding drive groove, while the other drive pin will slide within the corresponding drive groove, pulling the drive plate outwards and simultaneously driving the locking plate. The movement of the locking plate will disengage the anti-disengagement mechanism from the middle rail, removing the lock from the inner rail. At this point, the inner rail can be easily pulled out from the middle rail. Therefore, the wrench's structure and operation no longer distinguish between the left and right guide rails, allowing a single wrench to drive the locking mechanism whether it is moved up or down.

[0044] The locking mechanism design completely solves the pain points of existing technologies where disassembly mechanisms have a single operating direction, requiring users to distinguish between left and right guide rails or memorize specific unlocking directions. When disassembling the inner rail, users don't need to think or try; simply applying upward or downward force to the wrench completes the unlocking action, greatly simplifying the operation and improving the user experience. Therefore, users can quickly and intuitively complete disassembly tasks without repeated attempts, significantly improving disassembly efficiency and greatly reducing the risk of misoperation due to unfamiliarity with or confusion of the operating direction, avoiding potential damage to the mechanism or wasted time. This unlocking method, which eliminates the need to distinguish directions, is particularly important and user-friendly, especially in situations requiring frequent disassembly and assembly or in environments with limited visibility and space constraints. Both professional repair personnel and ordinary users can easily learn to use it, lowering the barrier to entry and making it suitable for widespread adoption.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
