Description

Technical Field

[0001] This invention belongs to the field of server slide rail technology, specifically relating to a server slide rail and fixing device. Background Technology

[0002] Server rails are connected to the front and rear ends of the server rack via brackets, allowing the rails to be installed in the server rack. The server chassis is installed inside the rack via the rails, and the server chassis can be easily pulled out and pushed back in the rack using the rails.

[0003] However, existing server rails are generally manufactured to fit the depth of the server rack, resulting in the need for different lengths of server rails for racks of different depths. This lack of versatility leads to high assembly costs. Summary of the Invention

[0004] Purpose of the invention: To provide a server slide rail and fixing device to solve the problems mentioned above.

[0005] Technical solution: Firstly, a fixing device for a server slide rail, the fixing device comprising: First support assembly and second support assembly. Both the first support assembly and the second support assembly are mounted on the server slide rail and are used to connect to and support other components of the slide rail.

[0006] Specifically, the first support assembly includes: a first support frame, an unlocking device, a locking device, a first elastic element, and a first connecting element. The second support assembly includes: a second support frame, a guide element, and a second connecting element.

[0007] The first support frame of the first support component and the second support frame of the second support component are slidably connected along the length direction. They are arranged in parallel and abut against each other, thereby forming a retractable slide rail base frame.

[0008] In a preferred embodiment of the present invention, the unlocking device is a mechanism that triggers the unlocking action, specifically comprising: an actuating element, a lever, and a stop. The actuating element is fixed to the first end of the lever, serving as the point where the operator applies force; the stop is fixed to the second end of the lever, used to drive the locking device. To facilitate the sliding of the lever, the lever and the stop are provided with oblong holes. The first connecting member passes through the oblong hole and securely connects the unlocking device as a whole to the first support frame, allowing the unlocking device to slide within a certain range relative to the first support frame.

[0009] As a preferred embodiment of the present invention, in order to achieve automatic reset after unlocking, the first support frame is provided with a first hole, the lever of the unlocking device is provided with a second hole, and the first elastic element (e.g., a tension spring) is installed between the first hole and the second hole. When the operator releases the actuating element, the restoring force of the first elastic element can pull the lever, causing it to reset the entire unlocking device.

[0010] As a preferred embodiment of the present invention, the locking device is a key component for achieving length locking, specifically comprising: a limiting fastener, a pin, and a second elastic element. The limiting fastener is designed as a symmetrical component to ensure force balance. Each end of the limiting fastener has a third hole and a fourth hole. The third hole is hinged to the upper and lower sides of the first support frame via a pin, allowing the limiting fastener to pivot around the pin. The second elastic element (e.g., a torsion spring or compression spring) is installed between the fourth holes of the two limiting fasteners, providing a continuous pivoting driving force for the limiting fastener. A limiting portion is also provided between the third and fourth holes of the limiting fastener, this limiting portion containing several toothed features for cooperating with a guide element to achieve locking.

[0011] As a preferred embodiment of the present invention, the second support frame of the second support assembly is provided with a plurality of mounting holes, and the guide is fixed to the second support frame by a second connector (such as a screw or rivet).

[0012] In a preferred embodiment of the present invention, the guide member is not horizontally positioned, but rather at a certain angle to the length direction of the second support frame. This inclined design is intended to create a more reliable locking mechanism with the limiting portion of the locking device.

[0013] As a preferred embodiment of the present invention, when the fixing device is in the locked state, the limiting fastener of the locking device, driven by the second elastic member, will have its toothed groove on its limiting part engage with the guide member. Since the guide member itself is inclined, this locking not only restricts the longitudinal (length direction) movement between the first and second support frames, but also uses the reaction force of the inclined surface to prevent the limiting fastener from further pivoting, thereby forming a self-locking mechanism and ensuring the stability of the locked state.

[0014] As a preferred embodiment of the present invention, a transverse channel is formed between the first support frame of the first support component and the second support frame of the second support component, and the fixing device is installed in the transverse channel.

[0015] Secondly, the present invention also provides a server slide rail including the aforementioned fixing device, comprising: a first bracket device, a second bracket device, and the aforementioned fixing device. The first bracket device is mounted on a first support component of the fixing device and is used to connect to the front end of the server rack; the second bracket device is mounted on a second support component of the fixing device and is used to connect to the rear end of the server rack.

[0016] Compared with the prior art, the present invention has the following beneficial effects: Versatility and cost: The fixing device of the present invention, through its relatively sliding first and second support components, allows the overall length of the slide rail assembly to be flexibly adjusted according to the actual cabinet depth, realizing the adaptation of a single specification of slide rail to cabinets of multiple depths, greatly reducing the manufacturing, inventory and installation costs of the slide rail.

[0017] Structural stability and ease of operation: The unlocking and locking devices adopt a modular design, with fewer parts and a simpler structure. The locking and unlocking process is logically clear and operates stably and reliably. The operator only needs to simply pull the actuating element to unlock and adjust; it automatically locks upon release. The simple operation effectively improves the assembly efficiency and stability of the slide rail.

[0018] Locking reliability: The inclined guide and the toothed limit fastener cooperate with each other. The inclined surface of the guide generates reverse constraint on the limit fastener in the locked state, forming a stable self-locking structure. This effectively prevents accidental unlocking due to vibration or accidental contact and improves the load-bearing safety of the slide rail. Attached Figure Description

[0036] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] A server slide rail and fixing device, the core of which is that the slide rail assembly can adapt to racks 6 of different depths through an adjustable fixing device 3.

[0038] See Figures 1 to 3 The server slide rail assembly of the present invention mainly includes: a first support device 1, a second support device 2, and a fixing device 3. The first support device 1 is used to connect to the front upright of the server rack 6, and the second support device 2 is used to connect to the rear upright of the server rack 6. The fixing device 3 is connected between the first support device 1 and the second support device 2, and its length is adjustable, thereby changing the overall length of the entire slide rail assembly.

[0039] Detailed structure of fixing device 3: like Figure 3 and combined Figure 4 , Figure 5 and Figure 9 , Figure 10 As shown, the fixing device 3 is mainly composed of a first support component 4 and a second support component 5 that can slide relative to each other.

[0040] The first support assembly 4 includes a generally groove-shaped first support frame 41, and an unlocking device 42, a locking device 43, a first elastic member 44, and a first connector 45 mounted on the first support frame 41.

[0041] The second support assembly 5 includes a second support frame 51 that can be nested inside or slidably engaged with the outside of the first support frame 41, and a guide 52 and a second connector 53 fixed on the second support frame 51.

[0042] The first support frame 41 and the second support frame 51 are parallel and abut against each other. They can move relative to each other along the length direction, thereby changing the overall length of the fixing device 3.

[0043] Detailed structure of unlocking device 42: like Figure 7As shown, the unlocking device 42 is the interface for operator adjustment, and it includes an actuating element 421, a lever 422, and a stop 423. The actuating element 421 (such as a button or wrench) is fixed to the first end 4221 of the lever 422, and the stop 423 is fixed to the second end 4222 of the lever 422. The lever 422 and the stop 423 have oblong holes. A first connecting element 45 (such as a rivet or screw) passes through these oblong holes and is fixedly connected to the first support frame 41. Thus, the unlocking device 42 is slidably constrained to the first support frame 41, and its sliding stroke is limited by the length of the oblong holes.

[0044] like Figure 5 and Figure 6 As shown, to achieve automatic reset of the unlocking device 42, the first support frame 41 is provided with a first hole 411, and the lever 422 is provided with a corresponding second hole 4223. The first elastic element 44, in this embodiment, is preferably a tension spring, with its two ends hooked onto the first hole 411 and the second hole 4223, respectively. When the lever 422 moves under the action of an external force, the first elastic element 44 is stretched and stores elastic potential energy.

[0045] Detailed structure of locking device 43: like Figure 8 As shown, the locking device 43 is the core of the length locking mechanism, and it includes a limiting fastener 431, a pin 432, and a second elastic element 433. The limiting fastener 431 is a symmetrical structural component, and in this embodiment, it is configured as a pair, located on the upper and lower sides of the first support frame 41, respectively. Each limiting fastener 431 has a third hole 4311 and a fourth hole 4312 at both ends. The pin 432 passes through the third hole 4311 and is fixed to the side wall of the first support frame 41, allowing the limiting fastener 431 to pivot freely around the pin 432. A second elastic element 433 is installed between the fourth holes 4312 of the two limiting fasteners 431, which is preferably a compression spring in this embodiment. This spring always applies a force to the two limiting fasteners 431, causing them to rotate towards each other (or away from each other). The specific direction depends on the installation method. In this embodiment, the elastic force causes the limiting portion 4313 of the limiting fastener 431 to tend to rotate towards the second support assembly 5. On the limiting fastener 431, between the third hole 4311 and the fourth hole 4312, there is also a protruding limiting part 4313. The limiting part 4313 is machined with multiple tooth grooves for engaging with the guide 52.

[0046] Detailed structure of the second support component 5: like Figure 9 and Figure 10As shown, the second support frame 51 has several holes for mounting the guide member 52. The guide member 52 is fixed to these holes by a second connector 53 (such as a screw). In particular, the guide member 52 is not parallel to the length direction of the second support frame 51, but is at a predetermined tilt angle θ (e.g., 15°-30°). This angle is designed to form a stable self-locking mechanism with the limiting portion 4313 of the limiting fastener 431 when locked.

[0047] Horizontal passageway: like Figure 3 As shown, a transverse channel is formed between the first support frame 41 of the first support component 4 and the second support frame 51 of the second support component 5, and the fixing device 3 is installed in the transverse channel; Specifically, the first support component 4 is composed of a first wall (bottom surface), a second wall (upper side) and a third wall (lower side), and the second support component 5 is composed of a fourth wall (bottom surface), a fifth wall (upper side) and a sixth wall (lower side). The other components of the fixing device 3 are installed in the transverse channel formed between the first wall of the first support component 4 and the fourth wall of the second support component 5.

[0048] Working principle and dynamic process: Locked status: like Figure 1 , Figure 11 and Figure 12 As shown, when the slide rail assembly is adjusted to the required length, it is in a locked state. In this state, the second elastic element 433 of the locking device 43 releases its elastic force, driving a pair of limiting fasteners 431 to pivot around the pin 432, causing the teeth on the limiting portion 4313 of the limiting fastener 431 to tightly engage and abut against the guide 52 of the second support assembly 5. Since the guide 52 itself is inclined, a normal pressure is generated when the teeth of the limiting portion 4313 contact it. A component of this pressure further forces the limiting fastener 431 to press tightly against the guide 52, preventing the limiting fastener 431 from pivoting in the opposite direction, thus forming a stable self-locking mechanism. At this time, any force attempting to pull the first support assembly 4 and the second support assembly 5 relative to each other will be canceled out by the engagement of the limiting fastener 431 and the guide 52, thus the length of the fixing device 3 is firmly locked.

[0049] Unlocked status: When the slide rail length needs to be adjusted to accommodate racks 6 of different depths, the operator only needs to operate the unlocking device 42. For example... Figure 13 and Figure 14As shown, the operator uses their finger to activate the actuating element 421, causing it to move in the direction shown. The actuating element 421 drives the lever 422 and the stop element 423 to move together. During the movement, the stop element 423 contacts the limiting fastener 431 of the locking device 43 (for example, contacts the tail of the limiting fastener 431), and overcomes the elastic force of the second elastic element 433, pushing the limiting fastener 431 to pivot in the opposite direction around the pin 432. This action causes the limiting portion 4313 of the limiting fastener 431 to lift off the guide 52 and disengage. At this point, the lock between the first support assembly 4 and the second support assembly 5 is released.

[0050] In the unlocked state, the operator can easily push or pull the first support component 4 or the second support component 5, causing them to slide relative to each other, thereby changing the overall length of the fixing device 3. When adjusted to a new length suitable for the depth of the cabinet 6, the operator simply releases the actuating element 421.

[0051] Reset and Relock: After the actuating element 421 is released, the previously stretched first elastic element 44 (tension spring) begins to recover, and its contraction force pulls the lever 422, causing the entire unlocking device 42 to slide in the opposite direction until the stop 423 returns to its initial position. After the stop 423 retracts, it releases the constraint on the limiting fastener 431. At this time, the compressed second elastic element 433 (compression spring) quickly releases its elastic force, driving the limiting fastener 431 to pivot again, causing its limiting part 4313 to re-engage and abut against the guide 52, and the fixing device 3 immediately returns to the locked state.

[0052] Application examples: like Figure 15 and Figure 16 As shown, the server slide rail of the present invention can easily adapt to racks of different depths. Figure 15 The image shows the slide rail assembly installed in a frame 6 with a depth of L1, at which point the fixing device 3 is in a short retracted state. Figure 16 The diagram illustrates the state when the same slide rail assembly is installed in a deeper rack 6 (L2>L1). In this case, through the aforementioned unlocking-adjustment-locking steps, the fixing device 3 is adjusted to a longer extended state, thus perfectly matching the rack depth. Therefore, the technical solution of this invention successfully achieves the versatility of a single slide rail assembly for racks of different depths.

[0053] In summary, this invention, through its meticulously designed fixing device 3, particularly the modular structure and linkage logic of its internal unlocking device 42 and locking device 43, not only achieves flexible adjustment of the slide rail length, solving the problem of poor versatility in existing technologies, but also ensures operational stability and reliability through a self-locking mechanism and reset design. The entire solution is simple in structure, low in cost, and highly effective.

[0054] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
