Description

Technical Field

[0001] This utility model relates to the field of server rack installation technology, and in particular to a card connection mechanism for computer server racks. Background Technology

[0002] A computer server rack is a standardized piece of equipment specifically designed for storing, managing, and protecting servers and related network devices. It is widely used in data centers, enterprise server rooms, and other similar environments. A server rack is a closed or open frame structure, consisting of a frame and cover panels (doors), typically rectangular in shape and placed on the floor. Its main function is to centrally house servers, network equipment (such as switches and routers), storage devices, etc., and to facilitate the fixing and removal of these devices via a rail system.

[0003] In existing technologies, servers are typically slidably installed inside server racks using a guide rail system. After the server is installed, it is usually secured to the rack using locking screws or other threaded fasteners to improve server stability, prevent it from sliding and moving, and avoid damage from falling and dropping, thus preventing unnecessary equipment and data loss. However, securing the server with screws or other threaded fasteners requires matching installation tools and is not convenient to install or remove. This reduces the ease of installation and removal. Therefore, there is an urgent need for a snap-fit ​​mechanism for computer server racks to solve the above-mentioned technical problems. Utility Model Content

[0004] This utility model discloses a snap-fit ​​mechanism for a computer server rack. By incorporating a quick-release locking mechanism, during server installation, two levers at the matching positions are first pulled up, compressing a first spring and moving a limiting plate until it is recessed into the slot. Then, the levers are rotated, locking the L-shaped ends into grooves on one side of the baffle, freeing the operator's hands. The server rack can then be slidably installed between the two outer rails. Once the server rack is fully installed, the two levers are pulled up again, rotated to reset, and released. The first spring returns to its original position, resetting the limiting plate until it extends out of the slot and aligns with the end face of the server rack, effectively securing the rack. The server body is further secured with double-limiting mechanisms to prevent damage to one mechanism from affecting the overall securing effect. This effectively prevents the server from sliding, moving, or even falling. When the server needs to be disassembled for maintenance, simply repeat the above steps to pull up the two levers and engage them in the grooves of the baffle to quickly and easily remove the server body. No screws or other threaded fasteners or matching installation and disassembly tools are required during these operations, making the installation and disassembly of the server body time-saving, labor-saving, and highly efficient. In summary, this solves the problems described in the background technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model discloses a card-connecting mechanism for a computer server rack, comprising a rack body and a server body. The rack body has a hinged door on the front, which is a glass door. Multiple through slots are provided on both sides of the rack body. Multiple sets of external rails are fixedly installed on both sides of the interior of the rack body. The external rails are in the shape of an inverted U. The server body is provided with multiple external rails, which are slidably installed between two external rails in the same set. Card-connecting slots are provided on the top and bottom surfaces of the external rails.

[0007] A quick-release locking mechanism includes a mounting frame, a pull rod, a stop plate, and a first spring. Multiple mounting frames, pull rods, a stop plates, and first springs are provided. The mounting frames are arranged in pairs, with two mounting frames in the same pair fixedly installed on both sides of the main body of the server rack. The pull rod is an L-shaped cylinder, with one end movably penetrating through the mounting frame. The side of the pull rod penetrating the mounting frame is rotatably connected to a limiting plate via a rotating connector. The limiting plate movably extends through a through-slot into the interior of the main body of the server rack, with one side of the limiting plate abutting against the end face of the server body. The abutment plate abuts against the outer wall of the main body of the server rack. The first springs are arranged in pairs, with one end of each pair of first springs in the same pair fixedly connected to the mounting frame, and the other end of each pair of first springs fixedly connected to the abutment plate.

[0008] A preliminary limiting and mounting mechanism is located on both sides of the server body and engages with the mounting slot.

[0009] Furthermore, the dimensions of the through groove match the dimensions of the limiting plate, and the outer surfaces of the limiting plate are all smooth surfaces.

[0010] Furthermore, the limiting plate, abutment plate, pull rod, and mounting bracket are all made of insulating materials.

[0011] Furthermore, the mounting bracket has a baffle on the side away from the main body of the cabinet, and the baffle has a groove on the side away from the mounting bracket.

[0012] Furthermore, the preliminary limiting and locking mechanism includes a mounting block, a second spring, a top plate, and a locking block. Multiple mounting blocks, second springs, top plates, and locking blocks are provided. The mounting blocks are grouped in pairs, with two mounting blocks in the same group fixedly installed on both sides of the server body. The second springs are grouped in pairs, with two second springs in the same group fixedly installed on the top of the mounting blocks. The top of the top plate is fixedly connected to the top of the second springs. A locking block is fixedly connected to the top of the top plate. The top plate abuts against the top and bottom surfaces of the outer track, and the locking block matches and engages with the locking groove.

[0013] Furthermore, two telescopic guide rods are fixedly connected to the top of the mounting block, and the telescopic ends of the telescopic guide rods are fixedly connected to the top of the top plate.

[0014] Furthermore, the outer track has a movable groove inside, which is connected to the snap-fit ​​groove. A pressure rod is movably installed in the movable groove. The bottom end of the pressure rod contacts the top of the snap-fit ​​block, and the top of the pressure rod movably passes through the top of the outer track.

[0015] The present invention has the following advantages over the prior art:

[0016] 1. This technical solution incorporates a quick-release locking mechanism, allowing the server body to slide between two outer rails during installation. After the server body is pushed in fully, the quick-release locking mechanism quickly and easily locks and secures it, effectively preventing subsequent sliding, movement, or even falling. When disassembling the server body for maintenance or repair, it can also be quickly and easily removed. Furthermore, neither screws nor other threaded fasteners, nor matching installation and disassembly tools are required for installation and disassembly, making the installation and disassembly of the server body time-saving, labor-saving, highly efficient, and practical.

[0017] 2. This technical solution incorporates a preliminary limiting and locking mechanism. During the sliding installation of the server body between the two outer rails, the preliminary limiting and locking mechanism can initially limit the server body, making it less prone to sliding and moving. This effectively prevents the server body from accidentally sliding or even falling off when operators use the levers and limiting plates to limit and fix the server body, further improving the safety of server body installation and making it highly practical.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] In the description of this utility model, it should be understood that the terms "surface", "side", "gap", "peripheral", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Specific Implementation Example 1:

[0028] Reference Figures 1-5 A card-connecting mechanism for a computer server rack includes a rack body 1 and a server body 2. The front of the rack body 1 is hinged with a cabinet door 3, which is a glass door. Multiple through slots 4 are provided on both sides of the rack body 1. Multiple sets of external rails 5 are fixedly installed on both sides of the inside of the rack body 1. The external rails 5 are in the shape of an inverted U. The server body 2 is provided with multiple external rails 5. The server body 2 is slidably installed between two external rails 5 in the same set. Card-connecting slots 6 are provided on the top and bottom surfaces of the external rails 5.

[0029] The quick-release locking mechanism 7 includes a mounting bracket 701, a pull rod 702, a contact plate 703, and a first spring 704. Multiple mounting brackets 701, pull rods 702, contact plates 703, and first springs 704 are provided. The mounting brackets 701 are arranged in pairs, with two mounting brackets 701 in the same pair fixedly installed on both sides of the cabinet body 1. The pull rod 702 is an L-shaped cylinder, with one end of the pull rod 702 movably passing through the mounting bracket 701. The side of the pull rod 702 passing through the mounting bracket 701 is rotatably connected to a limiting device via a rotating connector. The positioning plate 705 extends through the through slot 4 into the interior of the rack body 1, and one side of the positioning plate 705 is in contact with the end face of the server body 2. The abutment plate 703 abuts against the outer wall of the rack body 1. The first springs 704 are in pairs, and one end of each pair of first springs 704 in the same pair is fixedly connected to the mounting bracket 701, and the other end of each pair of first springs 704 in the same pair is fixedly connected to the abutment plate 703. The preliminary positioning and mounting mechanism 8 is located on both sides of the server body 2 and is engaged with the mounting slot 6.

[0030] The dimensions of the through groove 4 match the dimensions of the limiting plate 705, and the outer surface of the limiting plate 705 is smooth. The limiting plate 705, the abutment plate 703, the pull rod 702 and the mounting bracket 701 are all made of insulating material. The mounting bracket 701 has a baffle 706 on the side away from the main body 1 of the cabinet, and the baffle 706 has a groove on the side away from the mounting bracket 701.

[0031] In the specific implementation process, when installing the server body 2, first pull up the two levers 702 at the matching position to compress the first spring 704, causing the limiting plate 705 to move until the limiting plate 705 is housed in the through slot 4. Then rotate the lever 702 to lock the L-shaped bend end of the lever 702 into the groove on one side of the baffle 706, thus freeing the operator's hands. At this point, the server body 2 can be slidably installed between the two outer rails 5. After pushing the server body 2 to the bottom, pull up the two levers 702 again and rotate... After the reset is released, the first spring 704 also resets and rebounds, driving the limit plate 705 to reset until the limit plate 705 extends out of the through slot 4 and fits against the end face of the server body 2. This effectively limits and fixes the server body 2, thereby effectively preventing the server from sliding, moving, or even falling off. When it is necessary to disassemble the server body 2 for maintenance and repair, simply repeat the above operation, pull up the two levers 702 and lock them in the groove of the baffle 706, and the server body 2 can be quickly and easily pulled out and removed.

[0032] The dimensions of the through groove 4 match the dimensions of the limiting plate 705, and the outer surface of the limiting plate 705 is smooth to ensure the overall stability of the limiting plate 705 and reduce the sliding friction between the limiting plate 705 and the through groove 4, thereby facilitating the pulling and resetting of the limiting plate 705.

[0033] The limiting plate 705, the abutment plate 703, the pull rod 702 and the mounting bracket 701 are all made of insulating materials to ensure that the limiting plate 705, the abutment plate 703, the pull rod 702 and the mounting bracket 701 have good insulation performance, thereby improving the safety of the staff when installing and disassembling the server body 2.

[0034] After pulling up the lever 702, the lever 702 can be rotated to lock the L-shaped bend end of the lever 702 into the groove on one side of the baffle 706, thus freeing the operator's hands and facilitating the installation or removal of the server body 2. Specific Implementation Example 2:

[0036] Reference Figure 4 and Figure 5 In a preferred embodiment, the initial limiting and mounting mechanism 8 includes a mounting block 801, a second spring 802, a top plate 803, and a locking block 804. Multiple mounting blocks 801, second springs 802, top plates 803, and locking blocks 804 are provided. Multiple mounting blocks 801 are grouped in pairs, with two mounting blocks 801 in the same group fixedly mounted on both sides of the server body 2. Second springs 802 are grouped in pairs, with two second springs 802 in the same group fixedly mounted on the top of the mounting block 801. The top of the top plate 803 is fixedly connected to the top of the second spring 802. A locking block 804 is fixedly connected to the top of the top plate 803. The top plate 803 abuts against the top and bottom surfaces of the outer track 5. The locking block 804 matches and engages with the locking groove 6.

[0037] Two telescopic guide rods 805 are fixedly connected to the top of the mounting block 801. The telescopic ends of the telescopic guide rods 805 are fixedly connected to the top of the top plate 803. The outer track 5 has a movable groove 9 inside. The movable groove 9 is connected to the snap-fit ​​groove 6. A pressing rod 10 is movably installed in the movable groove 9. The bottom end of the pressing rod 10 contacts the top of the snap-fit ​​block 804. The top of the pressing rod 10 moves through the top of the outer track 5.

[0038] In the specific implementation process, when the server body 2 is slidably installed between the two outer rails 5, after the locking block 804 contacts the outer rail 5, the two top plates 803 can be pressed manually with both hands, so that the second spring 802 is compressed, and the locking block 804 is moved down until its top is lower than the top and bottom surfaces of the outer rail 5. Then the server body 2 can continue to be slidably installed. When the server body 2 is slidably installed to the bottom, the second spring 802 will rebound, causing the top plate 803 to move up, thereby causing the locking block 804 to move up until the locking block 804 matches and engages with the locking slot 6, thus initially limiting the server body 2 and making it difficult for it to slide or move easily. This effectively prevents the server body 2 from accidentally sliding or even falling off when the operator operates the lever 702 and the limiting plate 705 to limit and fix the server body 2.

[0039] Among them, the telescopic guide rod 805 can improve the overall stability of the top plate 803;

[0040] The pressure bar 10 is designed so that when disassembling the server body 2, pressing the two pressure bars 10 will cause them to move down in the movable slot 9, allowing the pressure bar 10 to push the latching block 804 out of the latching slot 6. This makes it easy for the latching block 804 to separate from the latching slot 6 and release the limiting fixation on the server body 2. At this time, it is convenient for the staff to pull out the server body 2.

[0041] Working principle: When installing the server body 2, first pull up the two levers 702 at the matching position to compress the first spring 704, which in turn moves the limiting plate 705 until it is retracted into the through slot 4. Then, rotate the lever 702 to lock the L-shaped bend end of the lever 702 into the groove on one side of the baffle 706, thus freeing the operator's hands. At this point, the server body 2 can be slidably installed between the two outer rails 5. During the process of sliding the server body 2 between the two outer rails 5, once the locking block 804 contacts the outer rail 5, the two top plates 803 can be manually pressed down with both hands, causing... The second spring 802 is compressed, causing the locking block 804 to move down until its top is lower than the top and bottom surfaces of the outer track 5. Then, the server body 2 can continue to slide and install. When the server body 2 is slid to the bottom, the second spring 802 will rebound, causing the top plate 803 to move up, thereby causing the locking block 804 to move up until the locking block 804 matches and engages with the locking slot 6, thus initially limiting the server body 2 and making it difficult for it to slide or move easily. This effectively prevents the server body 2 from accidentally sliding or even falling off when the operator performs the limiting and fixing operation on the server body 2 by operating the pull rod 702 and the limiting plate 705.

[0042] Once the server body 2 is initially fixed, the two levers 702 can be pulled up again, rotated to reset, and then released. The first spring 704 also resets and rebounds, driving the limiting plate 705 to reset until the limiting plate 705 extends out of the through slot 4 and fits against the end face of the server body 2. This effectively further limits and fixes the server body 2, forming a double-limiting fixation. This prevents the limiting and fixing effect of the server body 2 from being affected by the failure or damage of one of the limiting and fixing mechanisms, and effectively prevents the server from sliding, moving, or even falling off. When the server body 2 needs to be disassembled for maintenance, simply repeat the above operation, pull up the two levers 702 and lock them in the groove of the baffle 706, and the server body 2 can be quickly and easily pulled out and removed. In the above operation, no screws or other threaded fasteners are needed, nor are matching installation and disassembly tools required, making the installation and disassembly of the server body 2 time-saving, labor-saving, and highly efficient.
