Description

Technical Field

[0001] The present invention relates to the technical field of slide rails, and in particular to a slide rail with locking, sliding-in, and disassembly opening and closing mechanisms and its usage method. Background Art

[0002] Common slide rail devices include two-stage slide rails and three-stage slide rails. The three-stage slide rail usually includes an outer rail, a middle rail, and an inner rail. The outer rail is fixed to the server rack, the inner rail is fixed to both sides of the server, and the middle rail serves as a load-bearing rail and is connected between the outer rail and the inner rail to extend the moving range of the server, and enables the inner rail and the middle rail to slide back and forth relative to the outer rail along the length direction of the outer rail. Therefore, the server can be freely pulled out or pushed back through the slide rail device.

[0003] In actual use, after the server slides out with the inner rail, a locking mechanism needs to be provided on the inner rail to prevent the inner rail from accidentally sliding; when maintaining the server, the server also needs to be removed for easy operation.

[0004] In the prior art, a fixed limiting mechanism is usually provided between the inner rail and the middle rail to prevent the inner rail from accidentally sliding out or even disengaging; when the server needs to be disassembled and maintained, either the server is directly removed from the inner rail, or force needs to be applied to cause the inner rail to cross the limiting mechanism and then be removed synchronously with the server. The operation is quite inconvenient, and the inner rail is also prone to damage due to forced disassembly under load. Summary of the Invention

[0005] To solve the above problems, the present invention provides a slide rail with reasonable structure and locking, sliding-in, and disassembly opening and closing mechanisms and its usage method, so that while ensuring reliable locking in the slid-out state of the slide rail, sliding-in or disengaging and disassembling operations can be realized, which is convenient and smooth, greatly ensuring and facilitating the daily maintenance and use of the server, and having good practicability.

[0006] The technical solution adopted by the present invention is as follows:

[0007] A slide rail with locking, sliding-in, and disassembly opening and closing mechanisms includes a rail one and a rail two that are relatively slidably assembled along the length direction. On the side of the rail two facing the rail one, a locking block one and a locking block two are installed at intervals along the length direction; the locking block one is driven by a sliding-in unlocking mechanism to move in the width direction of the rail two, and the locking block two is driven by a disassembly unlocking mechanism to move in the width direction of the rail two; on the side of the rail one facing the rail two, a limiting protrusion is provided. As the rail two and the rail one relatively slide in the length direction, the limiting protrusion is clamped between the locking block one and the locking block two, constituting a two-way lock of the rail two and the rail one in the sliding direction.

[0008] As a further improvement of the above technical solution:

[0009] The sliding unlocking mechanism includes a long push rod slidably arranged along the length direction of the second rail, the inner end of the long push rod is located at a locking block, and a wedge surface is formed between the end of the long push rod and the locking block one. The movement of the long push rod in the length direction causes the locking block one to move in the width direction of the second rail to unlock.

[0010] A relatively sliding guide structure 1 and a reset structure 1 are respectively installed between the long push rod and the second rail, and between the locking block 1 and the second rail; the end of the long push rod is arranged to be a sliding inclined surface 1 toward the locking block 1, and the sliding inclined surface 1 is matched with the sliding inclined surface 2 on the locking block 1 to form a wedge surface fit.

[0011] The two ends of the rail located at the outer end of the long push rod are equipped with a slide-in trigger mechanism, and the slide-in trigger mechanism pushes the long push rod to move, thereby prompting the locking block to move.

[0012] The slide-in trigger mechanism includes a push plate slidably installed on the side of the second end of the rail, the inner side of the push plate is opposite to the outer end of the long push rod, and the outer side of the push plate extends out of the second rail and then folds and extends to form a pushing portion; a relatively sliding guide structure 2 and a reset structure 2 are installed between the push plate and the second rail.

[0013] The disassembly and unlocking mechanism includes a short pull rod slidably arranged along the length direction of the second rail. The short pull rod passes through the second locking block along the length direction. A wedge surface fit is formed between the short pull rod and the second locking block. The movement of the short pull rod in the length direction causes the second locking block to move and unlock in the width direction of the second rail.

[0014] A relatively sliding guide structure three and a reset structure three are installed between the locking block two and the rail two, and a relatively sliding guide structure four is installed between the short pull rod and the rail two; a disassembly slope one is provided in the middle of the short pull rod, and a through groove two is provided on the locking block two for the short pull rod to pass through, and a disassembly slope two is formed on the side surface of the through groove two to match the disassembly slope one, forming a wedge surface fit.

[0015] A disassembly trigger mechanism is installed at the end of the short pull rod away from the locking block 2, and the disassembly trigger mechanism is installed at the middle of the rail 2; when the rails 1 and 2 are bidirectionally locked in the sliding direction, the disassembly trigger mechanism is located outside the end of the rail 1.

[0016] The end of the short pull rod extends to form a mounting portion, and the disassembly trigger mechanism is a toggle block mounted on the side of the mounting portion; the sides of the mounting portion and the toggle block are fitted together via recessed holes and protruding blocks, and a fastener is installed through the toggle block toward the mounting portion.

[0017] A method for using the slide rail with a locking, sliding in, and disassembling opening and closing mechanism comprises the following steps:

[0018] The second rail slides out along the length direction relative to the first rail until the limiting protrusion on one side of the first rail crosses the first locking block on the side of the second rail, and the limiting protrusion is clamped between the first locking block and the second locking block, prompting the two-way locking of the second rail relative to the first rail in the sliding direction;

[0019] Push the long push rod in the sliding-in unlocking mechanism to drive the first locking block to move along the width direction of the second rail and disengage from locking the limiting protrusion, so that the second rail can slide into the first rail;

[0020] Pull the short pull rod in the disassembly unlocking mechanism to drive the second locking block to move along the width direction of the second rail and disengage from locking the limiting protrusion, so that the second rail can continue to move along the sliding-out direction relative to the first rail until the second rail disengages from the first rail to achieve disassembly.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The present invention can effectively ensure the reliable locking in the sliding direction after the second rail slides out relative to the first rail, and can also, according to actual needs, realize the sliding-in or detachment of the second rail relative to the first rail by unlocking the first locking block or the second locking block. The operation is convenient and smooth, greatly ensuring and facilitating the daily maintenance and use of the server, and having good practicability;

[0023] The present invention also has the following advantages:

[0024] The sliding-in triggering mechanism pushed by the long push rod in the sliding-in unlocking mechanism is arranged at the outer end of the second rail. Through the push of the push plate at the end and force transmission, the unlocking of the first locking block near the inner end of the second rail is realized, which is convenient for the actual force application operation and ensures the smoothness of unlocking;

[0025] The disassembly triggering mechanism pulled by the short pull rod in the disassembly triggering mechanism is arranged in the middle of the second rail. By manually applying force to the disassembly triggering mechanism and through force transmission, the unlocking of the second locking block is realized; compared with the force application of the sliding-in triggering mechanism, the operation of the disassembly triggering mechanism is more delicate and requires manual operation, which conforms to the actual use scenario and effectively avoids the misoperation of the disassembly triggering mechanism.

Specific embodiments

[0037] The following will describe the specific embodiments of the present invention with reference to the accompanying drawings.

[0038] As shown in Figure 1 , Figure 2 and Figure 3As shown in the figure, a slide rail with a locking, sliding-in, and disassembly opening and closing mechanism in this embodiment includes a rail one 10 and a rail two 20 that are relatively slidably assembled along the length direction. On the side of the rail two 20 facing the rail one 10, a locking block one 25 and a locking block two 45 are installed at intervals along the length direction. The locking block one 25 is driven by the sliding-in unlocking mechanism 2 to move in the width direction of the rail two 20, and the locking block two 45 is driven by the disassembly unlocking mechanism 4 to move in the width direction of the rail two 20. A limiting protrusion 101 is provided on the side of the rail one 10 facing the rail two 20. As the rail two 20 and the rail one 10 slide relative to each other in the length direction, the limiting protrusion 101 is clamped between the locking block one 25 and the locking block two 45, forming a two-way lock for the rail two 20 and the rail one 10 in the sliding direction.

[0039] In this embodiment, during actual operation, reliable locking in the sliding direction can be effectively ensured after the rail two 20 slides out relative to the rail one 10. Also, according to actual needs, by unlocking the locking block one 25 or the locking block two 45, the rail two 20 can be slid into or disengaged from the rail one 10.

[0040] As Figure 4 shown, the sliding-in unlocking mechanism 2 includes a long push rod 21 slidably arranged along the length direction of the rail two 20. The inner end of the long push rod 21 is located at the locking block one 25. A wedge surface fit is formed between the end of the long push rod 21 and the locking block one 25. The movement of the long push rod 21 in its length direction causes the locking block one 25 to move and unlock in the width direction of the rail two 20. Thus, through the long push rod 21 and in combination with the wedge surface fit, remote force transmission control for unlocking the locking block one 25 can be achieved, and the reliability of locking and unlocking is ensured by the wedge surface fit.

[0041] In this embodiment, the moving direction of the long push rod 21 relative to the rail two 20 is along the length direction of the rail two 20, and the moving direction of the locking block one 25 relative to the rail two 20 is along the width direction of the rail two 20. Thus, the wedge surface fit is effectively combined and utilized, and the locking block one 25 is driven to act by the force transmitted through the long push rod 21.

[0042] A relatively sliding guiding structure one and a reset structure one are respectively installed between the long push rod 21 and the rail two 20, and between the locking block one 25 and the rail two 20. The end of the long push rod 21 facing the locking block one 25 is provided with a sliding-in inclined surface one 213, and the sliding-in inclined surface one 213 is fitted with the sliding-in inclined surface two 251 on the locking block one 25 to form a wedge surface fit.

[0043] In this embodiment, a plurality of long holes one 211 are provided at intervals along the length direction of the long push rod 21. A guiding pin one 22 is installed on the rail two 20 and correspondingly passes through each of the long holes one 211. The relative movement of the guiding pin one 22 in the corresponding long hole one 211 forms the guiding structure one for the relative movement between the long push rod 21 and the rail two 20.

[0044] In this embodiment, an elastic member II (28) is installed between the middle part of the long push rod (21) and the track II (20). The elastic member II (28) ensures the reset of the long push rod (21) after moving and unlocking, constituting a first reset structure for the relative movement between the long push rod (21) and the track II (20).

[0045] In one of the embodiments, an intermediate block (27) is installed on the side of the track II (20) at the middle part of the long push rod (21). The long push rod (21) passes through between the intermediate block (27) and the track II (20). The long push rod (21) extends a first convex part (212) along the width direction of the track II (20), and an elastic member II (28) arranged along the length direction of the long push rod (21) is installed between the first convex part (212) and the intermediate block (27).

[0046] In this embodiment, a long hole arranged along the width direction of the track II (20) is formed on the locking block I (25), and a second guide pin (24) is installed through the long hole and facing the track II (20), so that the locking block I (25) can move relative to the track II (20) in the width direction guided by the fitting of the second guide pin (24) and the long hole, constituting a first guiding structure for the relative movement between the locking block I (25) and the track II (20).

[0047] In this embodiment, a support block (26) is installed on the track II (20) at the end of the moving direction of the locking block I (25), and an elastic member I (23) is installed between the locking block I (25) and the support block (26). The elastic member I (23) ensures the reset of the locking block I (25) after moving and unlocking relative to the track II (20), constituting a first reset structure for the relative movement between the locking block I (25) and the track II (20).

[0048] In this embodiment, the sliding-in inclined surface II (251) on the locking block I (25) is not only used to form a wedge surface fit with the long push rod (21), but also during the sliding-out operation of the track II (20) relative to the track I (10), as the sliding progresses, the limiting protrusion (101) on the track I (10) applies a force to the locking block I (25) through the sliding-in inclined surface II (251) to drive the locking block I (25) to move relative to the track II (20) until the limiting protrusion (101) passes over the locking block I (25) to achieve locking in the sliding-out state; the sliding-in inclined surface II (251) effectively ensures locking via the limiting protrusion (101).

[0049] A sliding-in trigger mechanism (1) is installed at the end of the track II (20) at the outer end of the long push rod (21), and the sliding-in trigger mechanism (1) pushes the long push rod (21) to move, thereby promoting the movement of the locking block I (25).

[0050] In this embodiment, through the arrangement of the sliding-in trigger mechanism (1) at the end of the track II (20), it is convenient to operate the long push rod (21), and the force is transmitted by the long push rod (21) to achieve remote unlocking of the locking block I (25).

[0051] Such as Figure 5As shown, the sliding trigger mechanism 1 includes a push plate 12 slidably mounted on the side surface at the end of the second rail 20. The inner side surface of the push plate 12 faces the outer end of the long push rod 21. The outer side surface of the push plate 12 extends and folds after protruding from the second rail 20 to form a pushing portion 122, which is convenient for pushing the push plate 12 and the long push rod 21.

[0052] In this embodiment, the sliding trigger mechanism 1 pushed by the long push rod 21 in the sliding unlocking mechanism 2 is arranged at the outer end of the second rail 20. Through the pushing of the push plate 12 at the end, via force transmission, the unlocking of the first locking block 25 near the inner end of the second rail 20 is realized, which is convenient for the actual force application operation and ensures the smoothness of unlocking.

[0053] A second guiding structure for relative sliding and a second reset structure are installed between the push plate 12 and the second rail 20.

[0054] In this embodiment, a plurality of long holes 121 are formed in the push plate 12, and a plurality of convex columns 13 or fifth guiding pins 14 fixed to the second rail 20 are installed through the long holes 121. The relative movement of the convex columns 13 and the fifth guiding pins 14 in the long holes 121 constitutes the second guiding structure for the relative movement between the push plate 12 and the second rail 20.

[0055] In this embodiment, a second support 15 is further installed on the side surface of the second rail 20, and a fourth elastic member 16 is installed between the second support 15 and the push plate 12. The fourth elastic member 16 ensures the reset of the push plate 12 after moving and unlocking, constituting the second reset structure for the relative movement between the push plate 12 and the second rail 20.

[0056] In this embodiment, a limiting block 17 is further installed on the second rail 20, and the movement and reset of the push plate 12 can be limited by the limiting block 17.

[0057] In this embodiment, an end plate 11 is installed via the convex column 13. The end plate 11 is arranged parallel to the side surface of the second rail 20. A space for accommodating and relatively moving the push plate 12 is formed between the end plate 11 and the second rail 20; the two side edges of the end plate 11 extend towards the two side edges of the second rail 20 and are clamped and limited to each other.

[0058] The disassembly unlocking mechanism 4 includes a short pull rod 41 slidably arranged along the length direction of the second rail 20. The short pull rod 41 passes through the second locking block 45 along the length direction. A wedge surface fit is formed between the short pull rod 41 and the second locking block 45. The movement of the short pull rod 41 in the length direction causes the second locking block 45 to move and unlock in the width direction of the second rail 20; thus, through the short pull rod 41 and in combination with the wedge surface fit, the force transmission control for unlocking the second locking block 45 can be realized, and the reliability and stability of locking and unlocking are ensured by the wedge surface fit.

[0059] In this embodiment, the moving direction of the short pull rod 41 relative to the second rail 20 is along the length direction of the second rail 20, and the moving direction of the second locking block 45 relative to the second rail 20 is along the width direction of the second rail 20, so as to effectively combine and utilize the wedge surface fit, and drive the second locking block 45 to act by transmitting force through the short pull rod 41.

[0060] As Figure 6 and Figure 7 shown, a third guiding structure and a third reset structure for relative sliding are installed between the second locking block 45 and the second rail 20, and a fourth guiding structure for relative sliding is installed between the short pull rod 41 and the second rail 20; a first disassembly inclined surface 411 is formed in the middle of the short pull rod 41, a second through groove 455 for the short pull rod 41 to pass through is formed in the second locking block 45, and a second disassembly inclined surface 456 fitted with the first disassembly inclined surface 411 is formed on the side surface of the second through groove 455, forming a wedge surface fit.

[0061] In this embodiment, a long hole four 453 arranged along the width direction of the second rail 20 is formed in the second locking block 45, and a third guiding pin 42 is installed through the long hole four 453 and towards the second rail 20, so that the second locking block 45 can move relative to the second rail 20 in the width direction guided by the fitting of the third guiding pin 42 and the long hole four 453, constituting the third guiding structure for relative movement between the second locking block 45 and the second rail 20.

[0062] In this embodiment, a first support 44 is installed on the second rail 20 in the moving direction of the second locking block 45, and a third elastic member 43 is installed between the second locking block 45 and the first support 44 to ensure the reset of the second locking block 45 relative to the second rail 20 after unlocking the movement, constituting the third reset structure for relative movement between the second locking block 45 and the second rail 20.

[0063] A through hole 454 for accommodating and relatively moving the first support 44 is formed in the middle of the second locking block 45.

[0064] In this embodiment, a first through groove 261 for the short pull rod 41 to pass through is formed in the support block 26, a limiting groove 262 extends downward in the middle of the first through groove 261, a second protruding portion 412 extending towards the width direction of the second rail 20 is formed in the middle of the short pull rod 41, and the second protruding portion 412 is fitted in the limiting groove 262 and relatively moves in the limiting groove 262; a second through groove 455 for the short pull rod 41 to pass through is formed in the second locking block 45, and the first through groove 261 and the second through groove 455 are located on the same straight line, constituting the fourth guiding structure for relative movement between the short pull rod 41 and the second rail 20.

[0065] In this embodiment, according to the actual design, a fitting structure can also be provided on the side surfaces of the first locking block 25 and the second locking block 45 facing the second rail 20, for example, an outwardly protruding clamping block 452 is fitted into the corresponding long hole of the second rail 20.

[0066] At the end of the short pull rod 41 away from the locking block two 45, a disassembly trigger mechanism 3 is installed, and the disassembly trigger mechanism 3 is installed at the middle part of the rail two 20; when the rail one 10 and the rail two 20 are locked bidirectionally in the sliding direction, the disassembly trigger mechanism 3 is located outside the end of the rail one 10.

[0067] In this embodiment, the disassembly trigger mechanism 3 pulled by the short pull rod 41 in the disassembly trigger mechanism 3 is arranged in the middle of the rail two 20. By manually applying force to the disassembly trigger mechanism 3 and through force transmission, the unlocking of the locking block two 45 is realized; compared with the force application of the sliding trigger mechanism 1, the operation of the disassembly trigger mechanism 3 is more delicate and requires manual operation, which conforms to the actual use scenario and effectively avoids misoperation of the disassembly trigger mechanism 3.

[0068] An installation part 413 is formed by extending the end of the short pull rod 41, and the disassembly trigger mechanism 3 is a toggle block assembled on the side of the installation part 413; the side surfaces of the installation part 413 and the toggle block that are in contact are assembled by clamping with concave holes and convex blocks, and a fastener is installed through the toggle block towards the installation part 413 to realize the stable and reliable installation of the toggle block on the installation part 413 of the short pull rod 41.

[0069] In this embodiment, by installing the toggle block on the installation part 413, the disassembly trigger mechanism 3 is formed, which is convenient for applying force to the end of the short pull rod 41.

[0070] In this embodiment, a long hole three 414 is formed through the installation part 413 and the toggle block, and a guide pin four 46 is installed through the long hole three 414 towards the side of the rail two 20 to realize the sliding installation support of the installation part 413 of the short pull rod 41 relative to the rail two 20.

[0071] In this embodiment, through the locking block one 25 and the locking block two 45 with similar structures on the rail two 20, combined with the layout of the sliding trigger mechanism 1 and the disassembly trigger mechanism 3 with similar structures, and matching the setting of the limit protrusion 101 on the rail one 10, reliable locking after the rail two 20 slides out relative to the rail one 10 is realized, and the sliding-in unlocking or sliding-out disassembly unlocking of the rail two 20 relative to the rail one 10 can be realized by selecting the unlocking of the locking block one 25 or the locking block two 45; the overall layout is reasonable and ingenious, the structure is simplified, and it is convenient to implement and use in practice.

[0072] In this embodiment, a guide inclined surface 451 can also be set at the end of the locking block two 45 facing the limit protrusion 101. When the rail two 20 needs to slide and be installed relative to the rail one 10 after disassembly, the limit protrusion 101 can apply force to the locking block two 45 through the guide inclined surface 451 to drive the locking block two 45 to move relative to the rail two 20 until the limit protrusion 101 passes over the locking block two 45 to realize locking in the slid-out state after reinstallation.

[0073] In this embodiment, the force transmission mechanism in the slide-in unlocking mechanism 2 of the unlocking locking block 1 25 is set as a long push rod 21, and the slide-in trigger mechanism 1 driven by the long push rod 21 is set at the end of the rail 2 20, which is convenient for the operation of switching from the locked state to the slide-in state, and the push plate 12 of the slide-in trigger mechanism 1 can be pushed without using hands;

[0074] In this embodiment, the force transmission mechanism in the disassembly unlocking mechanism 4 for unlocking the locking block 2 45 is set as a short pull rod 41, and the disassembly trigger mechanism 3 for driving the short pull rod 41 to be pulled is set in the middle of the rail 2 20. It can be conveniently operated manually to switch the slide rail from a locked state to a sliding disassembly state, and the ingenious arrangement of the operating position and the operating method can effectively avoid accidental movement of the short pull rod 41.

[0075] The method for using the slide rail with a locking, sliding in, and disassembling opening and closing mechanism of this embodiment includes the following steps:

[0076] Rail 2 20 slides out relative to Rail 1 10 along the length direction until the limiting protrusion 101 on the side of Rail 1 10 passes over the locking block 1 25 on the side of Rail 2 20, and the limiting protrusion 101 is clamped between the locking block 1 25 and the locking block 2 45, so that Rail 2 20 is bidirectionally locked relative to Rail 1 10 in the sliding direction.

[0077] When the rail 20 is slid out and locked relative to the rail 1 10, the rail 20 can be unlocked and slid in relative to the rail 1 10 according to actual operation requirements, or the rail 20 can be unlocked, slid out and disassembled relative to the rail 1 10.

[0078] The unlocking and sliding operation is: pushing the long push rod 21 in the sliding unlocking mechanism 2, driving the locking block 1 25 to move along the width direction of the rail 2 20 and disengage the locking of the limiting protrusion 101, so that the rail 2 20 can slide relative to the rail 1 10; specifically:

[0079] The push plate 12 extending out from the end of the rail 20 is pushed along the length direction thereof, and the push plate 12 pushes the long push rod 21. The wedge surface between the long push rod 21 and the locking block 25 cooperates to drive the locking block 25 to move relative to the width direction of the rail 20, so that the locking block 25 is disengaged from the locking restriction on the limit protrusion 101.

[0080] The unlocking and sliding disassembly operation is as follows: pull the short pull rod 41 in the disassembly unlocking mechanism 4 to drive the locking block 45 to move along the width direction of the rail 20 and disengage from the locking of the limiting protrusion 101, so that the rail 20 can continue to move along the sliding direction relative to the rail 1 10 until the rail 20 is disengaged from the rail 10 to achieve disassembly; specifically:

[0081] The artificial hand applies force to the disassembly trigger mechanism 3, pulling the short pull rod 41 to move towards the outer end of the second rail 20. Through the wedge surface cooperation between the short pull rod 41 and the second locking block 45, the second locking block 45 is driven to move in the width direction of the second rail 20, so that the second locking block 45 is disengaged from the locking restriction on the limit protrusion 101.

[0082] In this embodiment, the first rail 10 and the second rail 20 can be the middle rail and the inner rail in the existing three-section rail, or the outer rail and the middle rail, or the two rails in the existing two-section rail, which can achieve two-way locking when the two mutually sliding rails are in the sliding-out state, and unlock one of the two directions according to the operation requirements.

[0083] The layout of the present invention is reasonable and ingenious, and the structure is simplified. While ensuring reliable locking in the sliding-out state of the slide rail, it can achieve sliding-in or disassembly operations, which are convenient and smooth, greatly guaranteeing and facilitating the daily maintenance and use of the server, and having good practicability.

[0084] In this specification, each embodiment is described in a progressive manner. The key point of each embodiment is the difference from other embodiments. For the same and similar parts between the embodiments, reference can be made to each other.

[0085] The above description is an explanation of the present invention, not a limitation of the invention. The scope defined by the present invention can be seen in the claims, and any form of modification can be made within the protection scope of the present invention.
