Description

Technical Field

[0001] This utility model relates to the field of server slide rail technology, and in particular to an inner frame for server slide rails with a push-type two-way lock. Background Technology

[0002] A slide rail is a type of hardware component. In servers, a slide rail is a highly precise mechanical part. Through the slide rail assembly, servers can be stored layer by layer inside the rack. For example, first, the outer frame is installed on the server rack using front and rear brackets. Then, the side walls of the server chassis are installed on the inner frame. At this time, the server chassis is installed on the rack by inserting the inner frames on both sides into the outer frame.

[0003] To facilitate maintenance, upgrades, and troubleshooting of server hardware, current server slide rails typically feature a limiting mechanism on the inner frame. This mechanism is usually one-way locking (e.g., locking only when fully extended), relying on latches, springs, or buttons for fixation. Manual unlocking is required. When the limiting mechanism is not unlocked, it restricts the slider, preventing the outer frame from opening and facilitating server fixation during use. Furthermore, it prevents the slide rail from closing during maintenance (e.g., the drawer automatically jams when fully extended, requiring a button to close), thus facilitating server repair.

[0004] Existing server slide rail limit mechanisms typically consist of a single limit block or two limit blocks. When a single limit block performs bidirectional limiting, slide rail overshoot (i.e., the slide rail or server exceeds the preset stop position due to inertia during movement) is prone to occur. Two limit blocks are usually pulled by one component or two components respectively, which has a complex structure and often requires the design of new connecting parts to accommodate the adjustment and changes of the chassis pins, which is quite troublesome. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a server slide rail inner frame with a push-type two-way lock. The inner frame uses two limit blocks that work synchronously and work together with a push-to-unlock method, which has the function of automatic locking and easy operation, thereby achieving the technical effect of maintaining the stability of the server slide rail.

[0006] To solve the above-mentioned technical problems and achieve the above-mentioned technical effects, this utility model is implemented through the following technical solution: The technical solution of this utility model is: an inner frame for a server slide rail with a push-type two-way lock, including an inner frame, a movable plate slidably connected to the inner wall of the inner frame, a two-way lock groove being opened on one side of the upper surface of the movable plate, and a limiting block rotatably connected to the two-way lock groove on the inner wall of the inner frame. Two limiting blocks are provided, and the two limiting blocks are respectively provided on both sides of the bidirectional locking groove. Each limiting block has a protrusion on both sides. When a single limiting block is in the locked state, one of the protrusions moves downward and is located in the bidirectional locking groove, while the other protrusion moves upward and contacts the top of the inner wall of the inner frame. When a single limiting block is in the unlocked state, the two protrusions are at the same height.

[0007] Furthermore, the bidirectional locking groove is composed of a parallel section, a front guide section, a rear guide section, and a groove. The front guide section is composed of an upper inclined part, a parallel part, and a lower inclined part from top to bottom. The top of the upper inclined part is fixedly connected to the top of the moving plate, and the bottom of the lower inclined part is connected to the bottom of the parallel section. The rear guide section is composed of a vertical part and a horizontal part. The bottom end of the vertical part is fixedly connected to the other side of the parallel section, and the height of the horizontal part is higher than that of the parallel section. The bottom end of the groove is connected to the horizontal part in the rear guide section, and the top end of the groove is fixedly connected to the top of the moving plate.

[0008] Furthermore, the limiting block is fixedly connected to the moving plate via a connecting rod, and the limiting block has a storage groove inside that matches the connecting rod, with a connecting hole extending through the storage groove.

[0009] Furthermore, a pull ring is provided at the bottom of the limiting block, and a telescopic spring is provided between the two pull rings.

[0010] Furthermore, the protrusion rotates around the connecting rod. When one side of the protrusion moves to the bottom, the other side of the protrusion moves to the top, and the protrusion at the top contacts the inner wall of the inner frame.

[0011] Furthermore, the length of the movable plate is less than the length of the inner frame, and the height of the movable plate is less than the height of the inner frame.

[0012] Furthermore, a guide post is provided on the rear side of the inner wall of the inner frame, and a sliding groove adapted to the guide post is provided on the movable plate, so that the movable plate can move horizontally along the surface of the guide post through the sliding groove.

[0013] Furthermore, a push groove is provided on the rear side of the inner frame, and a through hole adapted to the push groove is provided on the back side of the inner frame.

[0014] Furthermore, an installation hole is provided inside the inner frame and on the front side of the guide post, and a slot adapted to the installation hole is provided through the surface of the movable plate.

[0015] The beneficial technical effects of this utility model are as follows: By setting two limiting blocks on both sides of the bidirectional locking groove, compared with the setting of a single limiting block, the two limiting blocks are mirrored. Compared with the method of a single limiting block, when the slide rail slides quickly, after passing through the limiting block on one side, it will be blocked by the limiting block on the other side. This is because the slide rail or server exceeds the preset stop position due to inertia during the movement. Compared with the method of pulling the two limiting blocks by one part or pulling the two parts separately, this solution triggers unlocking by pushing force, without the need for additional buttons or pull rings. The structure is simple and does not require redesigning the connecting parts according to the position of the chassis pin. It is easy to use. In addition, with the help of the telescopic spring, it can drive the two limiting blocks at the same time, avoiding the problem that the limiting block in one direction cannot lock in time during the rapid sliding of the slide rail, causing the slide rail or server to fall off. After unfolding, when the moving plate is released, the telescopic spring can also pull the limiting block to automatically lock the slide rail, which has strong stability.

[0018] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0019] See appendix Figure 1 - Appendix Figure 6As shown, an inner frame for a server slide rail with a push-type two-way lock includes an inner frame 2. A movable plate 1 is slidably connected to the inner wall of the inner frame 2. A push groove 5 is provided on the rear side of the inner frame 2. A through hole adapted to the push groove 5 is opened on the back of the inner frame 2. The length of the movable plate 1 is less than the length of the inner frame 2, and the height of the movable plate 1 is less than the height of the inner frame 2. A movable groove is formed between the top of the movable plate 1 and the inner frame 2, which allows the outer frame slider to move horizontally.

[0020] By setting the push groove 5, it is convenient for staff to push the moving plate 1 to move, so that the moving plate 1 can be better subjected to force and the operation can be more convenient.

[0021] The bidirectional locking groove 4 is composed of a parallel section 41, a front guide section 42, a rear guide section 43, and a groove 44. The front guide section 42 is composed of an upper inclined part, a parallel part, and a lower inclined part from top to bottom. The top of the upper inclined part is fixedly connected to the top of the moving plate 1, and the bottom of the lower inclined part is connected to the bottom of the parallel section 41. The rear guide section 43 is composed of a vertical part and a horizontal part. The bottom end of the vertical part is fixedly connected to the other side of the parallel section 41, and the height of the horizontal part is higher than that of the parallel section 41. The bottom end of the groove 44 is connected to the horizontal part in the rear guide section 43, and the top end of the groove 44 is fixedly connected to the top of the moving plate 1.

[0022] The inner wall of the inner frame 2 is rotatably connected to a limiting block 3 that is connected to the bidirectional locking groove 4. There are two limiting blocks 3, which are respectively located on both sides of the bidirectional locking groove 4. Each limiting block 3 has a protrusion 32 on both sides. When the limiting block 3 is locked, one protrusion 32 moves downward and is located in the bidirectional locking groove 4, while the other protrusion 32 moves upward and contacts the top of the inner wall of the inner frame 2. When the limiting block 3 is unlocked, the two protrusions 32 are at the same height.

[0023] As attached Figure 2 - Appendix Figure 4 As shown, when the moving plate 1 moves forward, the rear protrusion 32 on the rear limiting block 3 moves along the surface of the front guide section 42, and at the same time, the front protrusion 32 on the front limiting block 3 moves along the surface of the rear guide section 43, so that the two limiting blocks 3 are in parallel directions, thereby unlocking. At this time, the slider on the outer frame can move along the gap between the top of the moving plate 1 and the inner frame 2.

[0024] Furthermore, the limiting block 3 is fixedly connected to the moving plate 1 via the connecting rod 31. The protrusion 32 on the limiting block 3 rotates around the connecting rod 31. When one protrusion 32 is at the bottom of the connecting rod 31, the other protrusion 32 is at the top of the connecting rod 31. The limiting block 3 has a storage groove 33 that matches the connecting rod 31 inside. A connecting hole 34 is provided through the inside of the storage groove 33. The connecting rod 31 is rotatably connected to the inner frame 2 through the connecting hole 34 at one end. The storage groove 33 allows the other end of the connecting rod 31 to be stored so that it does not protrude from the surface of the limiting block 3, thus preventing the connecting rod 31 from protruding and affecting the normal movement of the outer frame.

[0025] A tension spring connected to the inner frame 2 is provided on the rear side of the movable plate 1. When the inner frame 2 moves forward and drives the limit block 3 to unlock, the tension spring is in the unfolded state. When the movable plate 1 is no longer under force, the tension spring pulls the movable plate 1 to reset. At this time, after the telescopic spring 11 pulls the two limit blocks 3 to reset, the limit blocks 3 can limit the slider on the outer frame in the opposite direction to prevent the server from moving due to the force on the slide rail during maintenance.

[0026] Furthermore, a pull ring 35 is provided at the bottom of the limiting block 3, and a telescopic spring 11 is provided between the two pull rings 35. By providing the telescopic spring 11, when the slider on the outer frame moves to the middle of the two limiting blocks 3 without pushing the moving plate 1, the two limiting blocks 3 can limit and fix the middle slider. When the moving plate 1 moves, the slider on the slide rail pushes the inner frame 2 forward, so that the connecting rod 31 on the outer side of the two limiting blocks 3 is guided by the front guide section 42 and the rear guide section 43, so that the limiting block 3 rotates around the connecting hole 34, so that the two protrusions 32 on the limiting block 3 are parallel, thereby facilitating the slider on the outer frame to move out. After unlocking, after the outer frame unfolds, the force applied to the inner frame 2 is released, and the telescopic spring 11 will pull the two limiting blocks 3 to reset, thereby limiting the slider in the opposite direction, avoiding the phenomenon that the slide rail or server exceeds the preset stop position, and preventing the limiting block 3 in one direction from not locking in time during the rapid sliding of the slide rail, which could cause the slide rail or server to fall off.

[0027] When the operator releases their grip and no longer applies force to the moving plate 1, the telescopic spring 11 will pull the two limit blocks 3 back to their original position via the pull ring 35. When the outer frame is subjected to force and the slider returns to the limit block 3, the limit block 3 will limit it to prevent the slide rail from shrinking, thus achieving automatic locking and increasing the stability of the slide rail.

[0028] Furthermore, the protrusion 32 rotates around the connecting rod 31. When one side of the protrusion 32 moves to the bottom, the other side of the protrusion 32 moves to the top, and the protrusion 32 at the top contacts the inner wall of the inner frame 2.

[0029] Initial state (as shown in the attached image) Figure 2 As shown in the diagram (limiting block 3), when the slider on the outer frame moves from between the moving plate 1 and the inner frame 2 and approaches the rear limiting block 3, the slider will pass through the rear limiting block 3 and then be stopped by the front limiting block 3. Alternatively, when the slider on the outer frame passes through the front limiting block 3 from the front of the inner frame 2, it will be stopped by the rear limiting block 3. Only when both limiting blocks 3 are in a horizontal state can the slider on the outer frame pass smoothly.

[0030] Furthermore, a guide post 21 is provided on the rear side of the inner wall of the inner frame 2, and a sliding groove adapted to the guide post 21 is provided on the movable plate 1. The movable plate 1 can move horizontally along the surface of the guide post 21 through the sliding groove.

[0031] The sliding groove and guide post 21 can assist the moving plate 1 to move horizontally on the inner wall of the inner frame 2.

[0032] Furthermore, an installation hole 22 is provided inside the inner frame 2 and on the front side of the guide post 21, and a slot adapted to the installation hole 22 is provided through the surface of the movable plate 1.

[0033] By setting a slot, after the movable plate 1 is fixed to the server by screwing a bolt into the mounting hole 22, when the staff pushes the movable plate 1 through the push groove 5, the movable plate 1 can move horizontally on the bolt surface through the slot, without affecting the bolt fixing or the normal operation of the movable plate 1.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
