[0001] This utility model relates to the field of server rack technology, and more specifically, to a server rack tray. Background Technology

[0002] A server rack is a metal frame structure used for the centralized installation, management, and protection of servers, network equipment, and other IT hardware. Its internal trays achieve high-density device management through a layered layout, while optimizing airflow to prevent hot air backflow and effectively isolating cables to reduce interference between devices. It integrates space planning, heat dissipation control, and cable management.

[0003] Most existing server rack trays are bolted to the inside of the rack. When users need to maintain the server rack, they must remove the trays, requiring this process to be repeated every time. This leads to inefficiency in equipment maintenance and layout adjustments. Furthermore, repeated tightening can cause thread stripping or bolt breakage, resulting in decreased reliability over long-term use. Therefore, we have proposed an improvement: a new server rack tray. Summary of the Invention

[0004] The purpose of this utility model is to address the issue that most existing server rack trays are fixed inside the rack with bolts. When users perform maintenance on the server rack, they need to remove the trays. This requires repeating the process every time the rack is maintained, resulting in low efficiency in equipment maintenance and layout adjustments. Furthermore, repeated tightening can easily cause thread stripping or bolt breakage, leading to a decrease in the reliability of the fixing after long-term use.

[0009] As a preferred technical solution of this application, a worm gear is rotatably connected to the inner wall of the working cavity, and a worm wheel is fixedly sleeved at the middle of the outer side of the two bidirectional screws. The worm gear and the two worm wheels mesh with each other.

[0010] As a preferred technical solution of this application, each of the two mounting plates is equipped with two pressing components for further fixing the tray body, and the four pressing components correspond one-to-one with the fixing grooves.

[0011] As a preferred technical solution of this application, the extrusion assembly includes a lifting cavity and a guide port. The lifting cavity is opened inside the mounting plate. There are two guide ports, which are symmetrically opened on both sides of the inner wall of the fixing groove and are connected to the lifting cavity.

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0020] As described in the background section, most existing server rack trays are fixed inside the rack with bolts. When users perform maintenance on the server rack, they need to remove the trays. This requires repeating the process every time the rack is maintained, resulting in low efficiency in equipment maintenance and layout adjustment. Furthermore, repeated tightening can cause stripped threads or broken bolts, leading to a decrease in the reliability of the fixing after long-term use.

[0021] To solve this technical problem, this utility model provides a server rack tray for managing the internal space of server racks.

[0022] For details, please refer to Figures 1-5 Server rack pallets specifically include: Two mounting plates 1 and a tray body 2 are provided. The tray body 2 is positioned between the two mounting plates 1. A fixing component 3 for fixing the tray body 2 between the two mounting plates 1 is installed at the lower end of the tray body 2.

[0023] The server rack tray provided by this utility model uses a fixing component 3 to install the tray body 2 between two mounting plates 1, which simplifies the installation and disassembly process of the tray body 2 and makes it easier for users to maintain the internal space of the rack. When fixing the tray body 2, the fixing component 3, in combination with the squeezing action of the squeezing component 4, supports the bottom of the fixing component 3, thereby improving the stability of the tray body 2 structure after installation.

[0024] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0025] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] Example 1, please refer to Figures 1-4A server rack tray includes two mounting plates 1 and a tray body 2. The tray body 2 is positioned between the two mounting plates 1. A fixing component 3 for fixing the tray body 2 between the two mounting plates 1 is installed at the lower end of the tray body 2. When it is necessary to fix the tray body 2, rotating the knob 309 drives the worm gear 307 to rotate, which drives the bidirectional screw 305 to rotate synchronously through the meshing worm wheel 308. When the bidirectional screw 305 rotates, the four fixing rods 306 slide synchronously along the sliding groove 304. The fixing rods 306 engage with the fixing grooves 302 of the mounting plate 1, thus fixing the tray body 2 between the two mounting plates 1. Since the worm wheel 308 and the worm gear 307 have a reverse self-locking function, it ensures that the fixing rods 306 will not shift or loosen under vibration. Similarly, reversing the knob 309 will allow the fixing rods 306 to be removed from the fixing grooves 302, simplifying the installation and disassembly process of the tray body 2 and making it easier for users to maintain the internal space of the server rack.

[0028] Furthermore, such as Figures 3-4 As shown, the fixing component 3 includes a reinforcing rib 301 and a fixing groove 302. The reinforcing rib 301 is fixedly connected to the lower end face of the pallet body 2. There are two sets of fixing grooves 302, which are arranged in pairs. The two sets of fixing grooves 302 are respectively opened on one side wall of the two mounting plates 1 near the pallet body 2. A working cavity 303 is opened in the middle of the reinforcing rib 301. Two sliding grooves 304 are opened on both sides of the reinforcing rib 301. The reinforcing rib 301 provides a rigid support frame for the pallet body 2, preventing the pallet body 2 from bending easily and significantly improving the service life of the pallet body 2.

[0029] Furthermore, such as Figure 4 As shown, the inner wall of the working cavity 303 is rotatably connected to two symmetrically arranged bidirectional screws 305. The two ends of the two bidirectional screws 305 penetrate through the inner walls of both sides of the working cavity 303, and the two ends of the two bidirectional screws 305 are respectively rotatably set inside four sliding grooves 304. Each of the four sliding grooves 304 is slidably connected to a fixed rod 306. The two ends of the two bidirectional screws 305 are respectively threaded into the four fixed rods 306. The four fixed rods 306 are respectively engaged with the four fixed grooves 302. When the bidirectional screws 305 rotate, the four fixed rods 306 slide synchronously along the sliding grooves 304. The fixed rods 306 engage with the fixed grooves 302 of the mounting plate 1, realizing balanced force fixation at the four corners of the tray body 2. This can effectively disperse vibration loads, avoid single-point stress concentration, and ensure a rigid connection between the tray body 2 and the mounting plate 1. While simplifying the operation process, it enhances the torsional resistance of the overall structure, so that the tray body 2 maintains a stable and reliable support state during cabinet operation.

[0030] Furthermore, such as Figure 4As shown, a worm gear 307 is rotatably connected to the inner wall of the working chamber 303. A worm wheel 308 is fixedly sleeved at the middle of the outer side of each of the two bidirectional screws 305. The worm gear 307 and the two worm wheels 308 mesh with each other. A knob 309 is rotatably connected to one side of the reinforcing rib 301. The output end of the knob 309 passes through the reinforcing rib 301 and is fixedly connected to one end of the worm gear 307. Rotating the knob 309 drives the worm gear 307 to rotate, which drives the bidirectional screws 305 to rotate synchronously through the meshing worm wheels 308. Since the transmission of the worm wheel 308 and the worm gear 307 has a reverse self-locking function, it ensures that the fixed rod 306 will not be displaced or loosened under vibration environment, which significantly improves the reliability of the device.

[0031] Example 2 further optimizes the server rack tray provided in Example 1, specifically, as follows: Figure 5 As shown, each of the two mounting plates 1 has two compression components 4 for further fixing the pallet body 2. The four compression components 4 correspond one-to-one with the fixing grooves 302. When fixing the pallet body 2, the fixing component 3, in combination with the compression action of the compression components 4, supports the bottom of the fixing component 3, thereby improving the stability of the pallet body 2 structure after installation.

[0032] Furthermore, such as Figure 5 As shown, the extrusion assembly 4 includes a lifting cavity 401 and a guide port 402. The lifting cavity 401 is opened in the mounting plate 1. There are two guide ports 402. The two guide ports 402 are symmetrically opened on both sides of the inner wall of the fixing groove 302, and the two guide ports 402 are connected to the lifting cavity 401. The two guide ports 402 are inclined upward from the outside to the inside. A connecting rod 406 is hinged to both sides of the upper end of the lifting plate 404. A moving rod 407 is slidably connected to both guide ports 402. The two moving rods 407 are rotatably connected to the upper side wall of the two connecting rods 406 near the fixed groove 302. Two symmetrically arranged counterweights 408 are fixedly connected to the lower end of the lifting plate 404. A limit block 409 is fixedly connected to the lower side of the inner wall of the lifting cavity 401. The limit block 409 is located below the lifting plate 404. As the fixed rod 306 slides into the fixed groove 302, its front end contacts the movable rod 407. Pushed by the fixed rod 306, the movable rod 407 slides upwards along the guide opening 402, causing the connecting rod 406 to rise. The connecting rod 406 rotates on the movable rod 407 and the lifting plate 404. With the movement of the movable rod 407 and the limitation imposed by the lifting cavity 401 on the lifting plate 404, which allows it to slide only vertically, the connecting rod 406 pulls the lifting plate 404 upwards a short distance, stretching the spring 403. This causes the pressing block 405 to move from the lifting cavity 401 into the fixed groove 302. As the fixed rod 306 continues to move, the pressing block 405 applies an upward pushing force to the fixed rod 306, causing the upper end of the fixed rod 306 to fit tightly against the upper end of the fixing groove 302, eliminating the gap between the fixed rod 306 and the inner wall of the fixing groove 302, thereby improving the stability of the pallet body 2 and preventing the pallet body 2 from vibrating. When the fixed rod 306 moves out of the fixing groove 302, the spring 403 returns to its original position, and under the action of the counterweight 408 and the pressing block 405, the pressing block 405 moves back into the lifting cavity 401, making it easier for the user to fix it next time. The limiting block 409 is used to limit the lifting plate 404, so that the lifting plate 404 stops descending after the spring 403 returns to its normal state.

[0033] Example 3 further optimizes the server rack tray provided in Example 1, specifically, as follows: Figure 2 and Figure 3 As shown, two mounting plates 1 are fixedly connected to two pads 5 on the side near the pallet body 2. Each of the four pads 5 has a positioning hole 6 at its center. Each of the four corners of the lower end of the pallet body 2 is fixedly connected to a positioning rod 7. The four positioning holes 6 are matched with the four positioning rods 7 one by one. The cooperation between the positioning rods 7 and the positioning holes 6 achieves rapid and accurate alignment between the pallet body 2 and the mounting plate 1 through mechanical reference points. This not only ensures the guiding stability of the pallet body 2 during installation, but also significantly improves the installation efficiency and structural reliability of the pallet body 2.

[0034] Furthermore, such as Figure 1 and Figure 2 As shown, both mounting plates 1 have multiple mounting holes 8 on both sides, and each mounting hole 8 has a fixing screw 9. The mounting plates 1 are fixed to the preset position of the cabinet column by the fixing screws 9.

[0035] The usage process of the server rack tray provided by this utility model is as follows: Mounting plate 1 is fixed to the preset position on the rack column using fixing screws 9. The positioning rod 7 under the tray body 2 is aligned with the positioning hole 6 in the center of the pad 5 for initial positioning. After the lower end of the tray body 2 contacts the upper end of the pad 5, the knob 309 is rotated to drive the worm gear 307 to rotate. The worm wheel 308 drives the bidirectional screw 305 to rotate synchronously. When the bidirectional screw 305 rotates, the four fixing rods 306 slide synchronously along the sliding groove 304. The fixing rods 306 and the fixing groove 302 of the mounting plate 1 are engaged, so that the tray body 2 can be fixedly installed between the two mounting plates 1. Since the worm wheel 308 and the worm gear 307 have a reverse self-locking function, it ensures that the fixing rods 306 will not be displaced or loosened under vibration. Similarly, the knob 309 can be reversed to remove the fixing rods 306 from the fixing groove 302, which simplifies the installation and disassembly process of the tray body 2 and makes it easier for users to maintain the internal space of the rack. As the fixed rod 306 slides into the fixed groove 302, its front end contacts the movable rod 407. As the fixed rod 306 pushes, the movable rod 407 slides upwards along the guide opening 402. The movable rod 407 then drives the connecting rod 406 upwards, and the connecting rod 406 rotates on the movable rod 407 and the lifting plate 404. With the movement of the movable rod 407, the connecting rod 406 pulls the lifting plate 404 upwards a certain distance, stretching the spring 403, thereby causing the pressing block 405 to move from the lifting cavity 401 into the fixed groove 302. Within 2, as the fixing rod 306 continues to move, the pressing block 405 applies an upward pushing force to the fixing rod 306, thereby making the upper end of the fixing rod 306 tightly fit against the upper end of the fixing groove 302, eliminating the gap between the fixing rod 306 and the inner wall of the fixing groove 302, thus improving the stability of the pallet body 2 and preventing the pallet body 2 from vibrating. When the fixing rod 306 moves out of the fixing groove 302, the spring 403 resets, and under the action of the counterweight 408 and the pressing block 405, the pressing block 405 moves back into the lifting cavity 401, making it easier for the user to fix it next time.
