Description

Technical Field

[0001] The utility model relates to the technical field of slide rails, in particular to a slide rail with locking, sliding-in, and dismounting opening and closing mechanisms. Background Art

[0002] Common slide rail devices include two-section slide rails and three-section slide rails. The three-section 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 is used as a carrying rail to connect 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 it is also easy for the inner rail to be damaged due to forced disassembly under load. Content of the Utility Model

[0005] To solve the above problems, the utility model provides a slide rail with locking, sliding-in, and dismounting opening and closing mechanisms, which has a reasonable structure. While ensuring reliable locking in the slid-out state of the slide rail, it can achieve sliding-in or disengaging and dismounting operations, which are convenient and smooth, greatly guaranteeing and facilitating the daily maintenance and use of the server, and having good practicability.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A slide rail with locking, sliding-in, and dismounting 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 dismounting 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 slide relatively in the length direction, the limiting protrusion is clamped between the locking block one and the locking block two, constituting a two-way lock in the sliding direction of the rail two and the rail one.

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

[0009] The sliding unlocking mechanism includes a long push rod that slides along the length of rail two. The inner end of the long push rod is located at a locking block. The end of the long push rod and the locking block one form a wedge surface engagement. The movement of the long push rod along its length causes the locking block one to move and unlock along the width of rail two.

[0010] A guide structure I and a reset structure I are respectively installed between the long push rod and the second rail, and between the locking block I and the second rail; the end of the long push rod facing the locking block I is set as a sliding inclined surface I, and the sliding inclined surface I and the sliding inclined surface II on the locking block I are fitted together to form a wedge surface fit.

[0011] A sliding trigger mechanism is installed at the end of the rail two located at the outer end of the long push rod. The sliding trigger mechanism pushes the long push rod to move, thereby causing the locking block one to move.

[0012] The sliding trigger mechanism includes a push plate slidably installed on the side of the end of the second rail. The inner side of the push plate is directly opposite the outer end of the long push rod. The outer side of the push plate extends out of the second rail and then folds over to form a pushing part. A guide structure two and a reset structure two that slide relative to each other are installed between the push plate and the second rail.

[0013] The disassembly and unlocking mechanism includes a short pull rod that slides along the length of rail two. The short pull rod passes through locking block two along its length, and the short pull rod and locking block two form a wedge-shaped fit. The movement of the short pull rod along its length causes locking block two to move and unlock along the width of rail two.

[0014] The locking block 2 and the rail 2 are equipped with a guide structure 3 and a reset structure 3 that slide relative to each other, and the short pull rod and the rail 2 are equipped with a guide structure 4 that slides relative to each other. The short pull rod has a disassembly inclined surface 1 in the middle, and the locking block 2 has a through groove 2 for the short pull rod to pass through. The side of the through groove 2 forms a disassembly inclined surface 2 that matches the disassembly inclined surface 1, thus forming a wedge-shaped fit.

[0015] A disassembly trigger mechanism is installed at the end of the short pull rod away from the second locking block. The disassembly trigger mechanism is installed in the middle of the second rail. When the first and second rails are locked in both directions in the sliding direction, the disassembly trigger mechanism is located outside the end of the first rail.

[0016] The short pull rod extends to form a mounting part, and the disassembly triggering mechanism is a toggle block fitted on the side of the mounting part; the mounting part and the side of the toggle block are fitted together by a concave hole and a convex block, and a fastener is installed through the toggle block toward the mounting part.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The utility model can effectively ensure the reliable locking of the sliding direction after the rail two slides out relative to the rail one. Also, according to actual needs, through the unlocking of the locking block one or the locking block two, the sliding in or detachment of the rail two relative to the rail one can be realized. The operation is convenient and smooth, greatly guaranteeing and facilitating the daily maintenance and use of the server, and having good practicability;

[0019] The utility model also has the following advantages:

[0020] The sliding-in trigger mechanism pushed by the long push rod in the sliding-in unlocking mechanism is arranged at the outer end of the rail two. Through the pushing of the push plate at the end, via force transmission, the unlocking of the locking block one near the inner end of the rail two is realized, which is convenient for the actual force application operation and ensures the smoothness of unlocking;

[0021] The detachment trigger mechanism pulled by the short pull rod in the detachment trigger mechanism is arranged in the middle of the rail two. By manually applying force to the detachment trigger mechanism, via force transmission, the unlocking of the locking block two is realized; compared with the force application of the sliding-in trigger mechanism, the operation of the detachment trigger mechanism is more delicate and requires manual operation by humans, which conforms to the actual use scenario and effectively avoids the misoperation of the detachment trigger mechanism.

[0033] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, a slide rail with locking, sliding, and disassembly opening and closing mechanisms in this embodiment includes a first rail 10 and a second rail 20 that are slidably mounted relative to each other along the length direction. Locking blocks 1 25 and 2 45 are installed at intervals along the length direction on the side of the second rail 20 facing the first rail 10. The first locking block 25 is driven by the sliding unlocking mechanism 2 to move in the width direction of the second rail 20, and the second locking block 45 is driven by the disassembly unlocking mechanism 4 to move in the width direction of the second rail 20. A limiting protrusion 101 is provided on the side of the first rail 10 facing the second rail 20. As the second rail 20 and the first rail 10 slide relative to each other in the length direction, the limiting protrusion 101 is engaged between the first locking block 25 and the second locking block 45, thus forming a bidirectional locking of the second rail 20 and the first rail 10 in the sliding direction.

[0035] In this embodiment, during actual operation, the sliding direction can be reliably locked after the second rail 20 slides out relative to the first rail 10. Alternatively, the second rail 20 can slide in or out relative to the first rail 10 by unlocking the first locking block 25 or the second locking block 45, depending on actual needs.

[0036] like Figure 4As shown, the sliding unlocking mechanism 2 includes a long push rod 21 that slides along the length of the second rail 20. The inner end of the long push rod 21 is located at the locking block 25. The end of the long push rod 21 and the locking block 25 form a wedge-shaped engagement. The movement of the long push rod 21 along its length causes the locking block 25 to move and unlock in the width direction of the second rail 20. Thus, the long push rod 21, combined with the wedge-shaped engagement, enables remote force transmission control of the locking block 25 to unlock. The wedge-shaped engagement ensures the reliability of locking and unlocking.

[0037] In this embodiment, the long push rod 21 moves along the length of the second rail 20, and the locking block 25 moves along the width of the second rail 20, thereby effectively combining and utilizing the wedge surface fit, and driving the locking block 25 to move through the force transmitted by the long push rod 21.

[0038] A guide structure I and a reset structure I are respectively installed between the long push rod 21 and the second rail 20, and between the locking block 25 and the second rail 20; the end of the long push rod 21 facing the locking block 25 is set as a sliding inclined surface 213, and the sliding inclined surface 213 and the sliding inclined surface 251 on the locking block 25 are fitted together to form a wedge surface fit.

[0039] In this embodiment, a plurality of elongated holes 211 are spaced apart along the length of the long push rod 21. Guide pins 22 corresponding to each elongated hole 211 are installed on the rail 20. The relative movement of the guide pins 22 in the corresponding elongated holes 211 constitutes a guide structure for the relative movement between the long push rod 21 and the rail 20.

[0040] In this embodiment, an elastic element 28 is installed between the middle of the long push rod 21 and the second rail 20. The elastic element 28 ensures the reset of the long push rod 21 after it moves and unlocks, thus forming the first reset structure after the long push rod 21 moves relative to the second rail 20.

[0041] In one embodiment, a middle block 27 is installed on the side of the second rail 20 located in the middle of the long push rod 21, and the long push rod 21 passes between the middle block 27 and the second rail 20; the long push rod 21 extends along the width direction of the second rail 20 and has a protrusion 212, and an elastic member 28 arranged along the length direction of the long push rod 21 is installed between the protrusion 212 and the middle block 27.

[0042] In this embodiment, a long hole is provided on the locking block 25 along the width direction of the rail 20. A guide pin 24 is installed through the long hole toward the rail 20, so that the locking block 25 can move relative to the rail 20 in the width direction with the guide pin 24 and the long hole as the guide, thus forming a guide structure 1 for relative movement between the locking block 25 and the rail 20.

[0043] In this embodiment, a support block 26 is installed on the second rail 20 at the end of the moving direction of the first locking block 25. An elastic member 23 is installed between the first locking block 25 and the support block 26. The elastic member 23 ensures the reset of the first locking block 25 relative to the second rail 20 after unlocking by movement, constituting a first reset structure for the relative movement between the first locking block 25 and the second rail 20.

[0044] In this embodiment, the sliding of the first locking block 25 into the second inclined surface 251 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 second rail 20 relative to the first rail 10, as the sliding progresses, the limiting protrusion 101 on the first rail 10 applies a force to the first locking block 25 through the second inclined surface 251 to drive the first locking block 25 to move relative to the second rail 20 until the limiting protrusion 101 passes over the first locking block 25 to achieve locking in the sliding-out state; the second inclined surface 251 effectively ensures locking via the limiting protrusion 101.

[0045] A sliding-in trigger mechanism 1 is installed at the end of the second rail 2 at the outer end of the long push rod 21. The sliding-in trigger mechanism 1 pushes the long push rod 21 to move, thereby causing the first locking block 25 to move.

[0046] In this embodiment, through the setting of the sliding-in trigger mechanism 1 at the end of the second rail 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 first locking block 25.

[0047] As Figure 5 shown, the sliding-in trigger mechanism 1 includes a push plate 12 slidably installed 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.

[0048] In this embodiment, the sliding-in trigger mechanism 1 pushed by the long push rod 21 in the sliding-in 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, unlocking of the first locking block 25 near the inner end of the second rail 20 is achieved, which is convenient for the actual force application operation and ensures smooth unlocking.

[0049] A second guiding structure and a second reset structure for relative sliding are installed between the push plate 12 and the second rail 20.

[0050] In this embodiment, a plurality of long holes 121 are formed in the push plate 12, and a plurality of convex columns 13 or 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 guiding pins 14 in the long holes 121 constitutes a second guiding structure for the relative movement between the push plate 1 and the second rail 20.

[0051] In this embodiment, a support 2 15 is also installed on the side of the second rail 20. An elastic element 4 16 is installed between the support 2 15 and the push plate 12. The elastic element 4 16 ensures the reset of the push plate 12 after it moves and unlocks, thus forming the reset structure 2 after the push plate 12 and the second rail 20 move relative to each other.

[0052] In this embodiment, a limit block 17 is also installed on track 20, which can limit the movement and reset of push plate 12.

[0053] In this embodiment, an end plate 11 is installed via a protruding post 13. The end plate 11 is arranged parallel to the side of the second rail 20. The end plate 11 and the second rail 20 form a space for the push plate 12 to be accommodated and move relative to each other. The two sides of the end plate 11 extend toward the two sides of the second rail 20 and are locked and limited to each other.

[0054] The disassembly and unlocking mechanism 4 includes a short pull rod 41 that slides along the length of the second rail 20. The short pull rod 41 passes through the second locking block 45 along its length. The short pull rod 41 and the second locking block 45 form a wedge-shaped engagement. The movement of the short pull rod 41 along its length causes the second locking block 45 to move and unlock in the width direction of the second rail 20. Thus, the force transmission control for unlocking the second locking block 45 can be achieved through the short pull rod 41 and the wedge-shaped engagement. The wedge-shaped engagement ensures the reliability and stability of locking and unlocking.

[0055] In this embodiment, the short pull rod 41 moves along the length of the second rail 20, and the locking block 45 moves along the width of the second rail 20, thereby effectively combining and utilizing the wedge surface fit, and driving the locking block 45 to move through the force transmitted by the short pull rod 41.

[0056] like Figure 6 and Figure 7 As shown, a guide structure three and a reset structure three are installed between the locking block 2 45 and the rail 2 20, and a guide structure four is installed between the short pull rod 41 and the rail 2 20; a disassembly inclined surface 1 411 is provided in the middle of the short pull rod 41, and a through groove 2 455 is provided on the locking block 2 45 for the short pull rod 41 to pass through. The side of the through groove 2 455 forms a disassembly inclined surface 2 456 that matches the disassembly inclined surface 1 411, forming a wedge-shaped fit.

[0057] In this embodiment, the locking block 2 45 has an elongated hole 453 arranged along the width direction of the rail 2 20. A guide pin 3 42 is installed through the elongated hole 453 toward the rail 2 20, so that the locking block 2 45 can move relative to the rail 2 20 in the width direction with the guide pin 3 42 and the elongated hole 453 as the guide, thus forming a guide structure 3 for relative movement between the locking block 2 45 and the rail 2 20.

[0058] In this embodiment, a support 44 is installed on the rail 20 located in the moving direction of the locking block 2 45. An elastic element 3 43 is installed between the locking block 2 45 and the support 44. The elastic element 3 43 ensures the reset of the locking block 2 45 after it moves and unlocks relative to the rail 2 20, thus forming the reset structure 3 after the relative movement between the locking block 2 45 and the rail 2 20.

[0059] The locking block 45 has a through hole 454 in the middle for the support 44 to be accommodated and move relative to it.

[0060] In this embodiment, the support block 26 has a through groove 261 through which the short tie rod 41 passes. The middle of the through groove 261 extends downward to form a limiting groove 262. The middle of the short tie rod 41 extends towards the width of the second rail 20 to form a protrusion 412. The protrusion 412 is fitted into the limiting groove 262 and moves relative to it within the limiting groove 262. The locking block 45 has a through groove 455 through which the short tie rod 41 passes. The through groove 261 and the through groove 455 are located on the same straight line, forming a guide structure four for the relative movement between the short tie rod 41 and the second rail 20.

[0061] In this embodiment, according to the actual design, a mounting structure can also be provided on the side of locking block 1 25 and locking block 2 45 facing rail 2 20, for example, the protruding card block 452 is mounted into the corresponding elongated hole of rail 2 20.

[0062] A disassembly trigger mechanism 3 is installed at the end of the short pull rod 41 away from the locking block 2 45. The disassembly trigger mechanism 3 is installed in the middle of the rail 2 20. When the rail 1 10 and the rail 2 20 are locked in both directions in the sliding direction, the disassembly trigger mechanism 3 is located outside the end of the rail 1 10.

[0063] In this embodiment, the disassembly trigger mechanism 3, which is pulled by the short pull rod 41 in the disassembly trigger mechanism 3, is set in the middle of the second rail 20. By manually applying force to the disassembly trigger mechanism 3, the locking block 2 45 is unlocked through force transmission. Compared with the force applied by sliding into the trigger mechanism 1, the operation of the disassembly trigger mechanism 3 is more precise and requires manual operation, which is in line with the actual use scenario and effectively avoids misoperation of the disassembly trigger mechanism 3.

[0064] The end of the short pull rod 41 extends to form a mounting part 413. The disassembly triggering mechanism 3 is a toggle block fitted on the side of the mounting part 413. The mounting part 413 and the side of the toggle block are fitted together by a concave hole and a convex block. Fasteners are installed through the toggle block toward the mounting part 413 to achieve stable and reliable installation of the toggle block on the mounting part 413 of the short pull rod 41.

[0065] In this embodiment, the installation of the toggle block on the mounting part 413 constitutes the disassembly trigger mechanism 3, which facilitates the application of force to the end of the short pull rod 41.

[0066] In this embodiment, an elongated hole 414 is provided through the mounting part 413 and the actuating block. A guide pin 46 is installed through the elongated hole 414 toward the side of the rail 20 to realize the sliding mounting support of the short tie rod 41 mounting part 413 relative to the rail 20.

[0067] In this embodiment, by using locking blocks 25 and 45 with similar structures on rail 20, combined with the corresponding sliding trigger mechanism 1 and disassembly trigger mechanism 3 with similar structures, and matching the upper limit protrusion 101 of rail 10, reliable locking of rail 20 after sliding out relative to rail 10 is achieved. Furthermore, by unlocking locking blocks 25 or 45, sliding unlocking or sliding disassembly unlocking of rail 20 relative to rail 10 can be achieved. The overall layout is reasonable and ingenious, the structure is simplified, and it is easy to implement and use in practice.

[0068] In this embodiment, a guide slope 451 can also be provided at the end of the locking block 2 45 facing the limiting protrusion 101. When the disassembled rail 2 20 needs to be slidably installed relative to rail 1 10, the limiting protrusion 101 can apply force to the locking block 2 45 through the guide slope 451 to drive the locking block 2 45 to move relative to rail 2 20 until the limiting protrusion 101 passes over the locking block 2 45 to achieve locking in the sliding state after reinstallation.

[0069] In this embodiment, the force transmission mechanism in the sliding unlocking mechanism 2 of the locking block 1 25 is set as a long push rod 21, and the sliding trigger mechanism 1 that drives the long push rod 21 is set at the end of the rail 2 20, which facilitates the operation of switching from the locked state to the sliding state, and can even push the push plate 12 of the sliding trigger mechanism 1 without using the hand.

[0070] In this embodiment, the force transmission mechanism in the disassembly and unlocking mechanism 4 of the unlocking and locking block 2 45 is set as a short pull rod 41, and the disassembly triggering mechanism 3 that drives the short pull rod 41 to pull is set in the middle of the rail 2 20. This allows for convenient manual operation, enabling the slide rail to switch from the locked state to the sliding disassembly state. Furthermore, the clever arrangement of the operation position and operation method effectively avoids accidental movement of the short pull rod 41.

[0071] The method of using the slide rail with locking, sliding, and disassembly opening / closing mechanisms in this embodiment includes the following steps:

[0072] Rail 20 slides out along the length direction relative to Rail 10 until the limiting protrusion 101 on the side of Rail 10 passes over the locking block 25 on the side of Rail 20. The limiting protrusion 101 is engaged between the locking block 25 and the locking block 45, causing Rail 20 to be locked in both directions relative to Rail 10 in the sliding direction.

[0073] With rail 20 locked relative to rail 10, rail 20 can be unlocked and slid in relative to rail 10, or rail 20 can be unlocked, slid out, and disassembled relative to rail 10, depending on actual operational needs.

[0074] The unlocking and sliding operation is as follows: Pushing the long push rod 21 in the sliding unlocking mechanism 2 causes the locking block 25 to move along the width direction of the second rail 20, thus disengaging from the limiting protrusion 101, allowing the second rail 20 to slide in relative to the first rail 10; specifically:

[0075] The push plate 12, which extends outward along the length of the second rail 20, is pushed. The push plate 12 pushes the long push rod 21. Through the wedge-shaped engagement between the long push rod 21 and the locking block 25, the locking block 25 is driven to move relative to the width of the second rail 20, so that the locking block 25 is released from the locking restriction of the limiting protrusion 101.

[0076] The unlocking and disassembly operation is as follows: Pull the short lever 41 in the disassembly and unlocking mechanism 4 to drive the locking block 45 to move along the width direction of the second rail 20 and disengage from the limiting protrusion 101, so that the second rail 20 can continue to move relative to the first rail 10 in the sliding direction until the second rail 20 disengages from the first rail 10 and disassembly is achieved; specifically:

[0077] The manual force is applied to the disassembly trigger mechanism 3, pulling the short pull rod 41 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 relative to the width direction of the second rail 20, so that the second locking block 45 is released from the locking restriction of the limit protrusion 101.

[0078] In this embodiment, rail 10 and rail 20 can be the middle rail and inner rail in an existing three-section rail, or the outer rail and middle rail, or two rails in an existing two-section rail. It can realize bidirectional locking when the two sliding rails are in the sliding state, and unlocking of one direction of the bidirectional lock according to the operation requirements.

[0079] This utility model has a reasonable and ingenious layout and a simplified structure. While ensuring reliable locking when the slide rail is out, it can also achieve sliding in or disassembly operations, which is convenient and smooth. It greatly ensures and facilitates the daily maintenance and use of the server, and has good practicality.

[0080] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0081] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.

As rail 2 (20) and rail 1 (10) slide relative to each other in the length direction, limiting protrusion (101) is engaged between locking blocks 1 (25) and 2 (45), forming a bidirectional locking of rail 2 (20) and rail 1 (10) in the sliding direction.

2. The slide rail with locking, sliding, and disassembly opening / closing mechanisms as described in claim 1, characterized in that: The sliding unlocking mechanism (2) includes a long push rod (21) that slides along the length of the second rail (20). The inner end of the long push rod (21) is located at the locking block (25). The end of the long push rod (21) and the locking block (25) form a wedge surface fit. The movement of the long push rod (21) along the length of the long push rod causes the locking block (25) to move and unlock in the width direction of the second rail (20).

3. A slide rail with a locking, sliding, and disassembly opening / closing mechanism as described in claim 2, characterized in that: The long push rod (21) and the second rail (20) are respectively equipped with a guide structure and a reset structure that slides relative to each other. The end of the long push rod (21) is set to slide into the first inclined surface (213) facing the first locking block (25). The first inclined surface (213) and the second inclined surface (251) on the first locking block (25) are fitted together to form a wedge surface fit.

4. A slide rail with a locking, sliding, and disassembly opening / closing mechanism as described in claim 2, characterized in that: A sliding trigger mechanism (1) is installed at the end of the second rail (20) located at the outer end of the long push rod (21). The sliding trigger mechanism (1) pushes the long push rod (21) to move, thereby causing the locking block (25) to move.

5. A slide rail with a locking, sliding, and disassembly opening / closing mechanism as described in claim 4, characterized in that: The sliding trigger mechanism (1) includes a push plate (12) slidably installed on the side of the end of the second rail (20). The inner side of the push plate (12) is directly opposite to the outer end of the long push rod (21). The outer side of the push plate (12) extends out of the second rail (20) and then folds and extends to form a pushing part (122). A guide structure II and a reset structure II that slide relative to each other are installed between the push plate (12) and the second rail (20).

6. A slide rail with a locking, sliding, and disassembly opening / closing mechanism as described in claim 1, characterized in that: The disassembly and unlocking mechanism (4) includes a short pull rod (41) that slides along the length of the second rail (20). The short pull rod (41) passes through the second locking block (45) along the length direction. The short pull rod (41) and the second locking block (45) form a wedge-shaped fit. The movement of the short pull rod (41) along the length direction causes the second locking block (45) to move and unlock in the width direction of the second rail (20).

7. A slide rail with a locking, sliding, and disassembly opening / closing mechanism as described in claim 6, characterized in that: The locking block 2 (45) and the rail 2 (20) are equipped with a relative sliding guide structure 3 and a reset structure 3, and the short pull rod (41) and the rail 2 (20) are equipped with a relative sliding guide structure 4; the short pull rod (41) has a disassembly inclined surface 1 (411) in the middle, and the locking block 2 (45) has a through groove 2 (455) for the short pull rod (41) to pass through. The side of the through groove 2 (455) forms a disassembly inclined surface 2 (456) that matches the disassembly inclined surface 1 (411), thus forming a wedge surface fit.

8. A slide rail with a locking, sliding, and disassembly opening / closing mechanism as described in claim 6, characterized in that: A disassembly trigger mechanism (3) is installed at the end of the short pull rod (41) away from the locking block 2 (45). The disassembly trigger mechanism (3) is installed in the middle of the rail 2 (20). When the rail 1 (10) and the rail 2 (20) are locked in both directions in the sliding direction, the disassembly trigger mechanism (3) is located outside the end of the rail 1 (10).

9. A slide rail with a locking, sliding, and disassembly opening / closing mechanism as described in claim 8, characterized in that: The short pull rod (41) extends to form a mounting part (413) at its end. The disassembly triggering mechanism (3) is a toggle block fitted on the side of the mounting part (413). The mounting part (413) and the side of the toggle block are fitted together by a concave hole and a convex block. Fasteners are installed through the toggle block toward the mounting part (413).
