Description

Technical Field

[0001] This invention relates to the field of server rack vibration reduction, and in particular to a server rack seismic energy dissipation device. Background Technology

[0002] A network server rack is a network cabinet used to house servers. It is used to assemble and install panels, plug-ins, boxes, electronic components, devices, and mechanical parts and components to form a complete installation box. A server rack consists of a frame and a cover plate, and generally has a rectangular shape and is placed on the ground.

[0003] Currently, most network server racks are fixed to the ground using support frames and multiple bolts. During earthquakes or other shaking events, the support frames can sway, twist, and deform, making it difficult for the server rack to withstand significant kinetic energy. This can lead to the rack collapsing or being destroyed, leaving the servers inside with little protection. To address this, shock-absorbing springs are typically installed on the outside of the server rack to dissipate energy and improve its shock resistance.

[0004] However, in related technologies, directly adding shock-absorbing springs will cause the server rack to be in a constant state of shock absorption and energy dissipation. For some weak earthquakes that will not damage the server rack, the server rack will shake due to the operation of the shock-absorbing springs, which will cause the network server to have unstable connections with the outside world and thus lead to disconnection. Therefore, the method of adding shock-absorbing springs has poor applicability and is unreliable.

[0005] Therefore, how to effectively improve the applicability of seismic energy dissipation devices for server racks is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to provide a server rack earthquake energy dissipation device, which can distinguish different types of earthquakes, ensure the stability of the server rack, and effectively dissipate the kinetic energy generated by earthquakes.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A server rack seismic energy dissipation device, comprising:

[0009] The shock absorption mechanism includes a cover, a swing rod, a limiting ring, and a shock absorption assembly. The cover and the limiting ring are both sleeved on the swing rod. The first end of the swing rod extends out of the cover and is connected to the limiting ring. The first end of the swing rod is used to install the server rack. The shock absorption assembly is installed between the cover and the swing rod.

[0010] The limiting mechanism includes several fixed slide rails and several slide rods. The fixed slide rails are fixedly installed on the cover, and the slide rods are movably installed on the fixed slide rails. The slide rods can slide to the locked position or the unlocked position.

[0011] When the slide rod is in the locked position, one end of the slide rod abuts against the limiting ring to lock the cover; when the slide rod is in the unlocked position, one end of the slide rod separates from the limiting ring to unlock the cover, and the cover and the swing rod can swing relative to each other.

[0012] On the other hand, one end of the swing rod is provided with a counterweight, and the other end is provided with a placement platform for placing and connecting the server rack. The limiting ring is sleeved on the placement platform, and the limiting ring is adapted to the size of the placement platform.

[0013] On the other hand, the limiting ring is provided with a limiting ring groove on the side near the cover, and the slide rod is provided with a pressing block at the end away from the fixed slide rail. The pressing block is adapted to the shape of the limiting ring groove so that the pressing block abuts against the inner wall of the limiting ring groove.

[0014] On the other hand, the swing rod is also provided with a rolling ball, which is located between the counterweight and the limiting ring and close to the limiting ring. The cover is sleeved between the rolling ball and the limiting ring, and the cover can swing relative to the rolling ball.

[0015] On the other hand, the shock absorption assembly includes several shock absorption elastic components, one end of which is connected to the counterweight and the other end of which is connected to the inner wall of the cover; each of the shock absorption elastic components is distributed sequentially along the circumference of the counterweight.

[0016] On the other hand, the shock absorption assembly also includes an arc-shaped sleeve, an arc-shaped rod, and a first telescopic elastic component. The arc-shaped rod and the first telescopic elastic component are both located inside the arc-shaped sleeve. One end of the first telescopic elastic component is mounted on the swing rod, and the other end is connected to the arc-shaped rod. An impact ball is provided at the end of the arc-shaped rod away from the swing rod. The impact ball is used to impact the cover when the swing rod swings.

[0017] On the other hand, the limiting mechanism also includes a second telescopic elastic component and a rope. The second telescopic elastic component is installed in the fixed slide rail. A stop is fixedly connected to the outer surface of the slide rod. The second telescopic elastic component is fixedly connected between the stop and the fixed slide rail. The stop is located in the fixed slide rail. The end of the slide rod away from the limiting ring is connected to the first end of the rope.

[0018] It also includes a linkage mechanism connected to the second end of the rope, which is used to pull the rope to move the slide bar to the locking position. The second telescopic elastic component is used to drive the slide bar to the unlocking position when the linkage mechanism releases the rope.

[0019] On the other hand, it also includes a support frame, on which the cover is mounted;

[0020] The linkage mechanism includes a fixed shaft, a sliding tube, an electric telescopic rod, and a locking assembly. The fixed shaft is mounted on the support frame, the sliding tube is movably sleeved on the fixed shaft, and the sliding tube is connected to the second end of the rope. The locking assembly is connected to the electric telescopic rod and is used to lock or release the sliding tube under the drive of the electric telescopic rod.

[0021] On the other hand, the snap-fit ​​assembly includes a connecting plate, at least two hinge rods, a limiting sleeve, snap-fit ​​posts, and a third telescopic elastic component. The periphery of the slide tube is provided with a snap-fit ​​groove, and the number of snap-fit ​​posts and the snap-fit ​​grooves are the same and correspond one-to-one.

[0022] The limiting mechanism further includes a first roller and a second roller. The first roller is mounted on the cover and is located close to the fixed slide rail. The second roller is mounted on the edge of the cover away from the limiting ring. The rope is connected to the slide tube after passing through the first roller and the second roller in sequence from the end of the slide rod.

[0023] One side of the connecting plate is connected to the electric telescopic rod, and the other side has a hinge rod at each end. The side of the hinge rod away from the connecting plate is hinged to the locking post. The locking post and the third telescopic elastic component are both located inside the limiting sleeve. The electric telescopic rod can push the connecting plate to move, thereby pushing each of the hinge rods to separate. The hinge rod drives the locking post to move and compress the third telescopic elastic component. The locking post releases the slide tube.

[0024] The snap-fit ​​post is provided with a guide slope. When the slide tube moves toward the snap-fit ​​post, the slide tube abuts against the guide slope of the snap-fit ​​post to push the snap-fit ​​post to compress the third telescopic elastic component. When the snap-fit ​​post enters the slot, the third telescopic elastic component drives the snap-fit ​​post to reset.

[0025] It also includes a pedal, which is mounted on the slide tube and is used to drive the slide tube to slide toward the locking post.

[0026] On the other hand, it also includes:

[0027] Seismographs are used to detect earthquake magnitudes.

[0028] The controller, connected to the seismograph and the electric telescopic rod, is used to control the electric telescopic rod to lock or release the sliding tube when the earthquake level reaches a preset level.

[0029] The server rack earthquake energy dissipation device provided by this invention has the following advantages: With the damping mechanism in place, when an earthquake occurs, the server rack will shake due to the earthquake's influence. The server rack will cause the swing arm in the damping mechanism to deflect. After the swing arm deflects, it will dissipate energy through the damping components, reducing the kinetic energy generated by the earthquake. This allows the device to withstand larger vibrations, preventing the server rack from disintegrating or being damaged, thus effectively protecting the servers inside the server rack.

[0030] Simultaneously, through the setting of the limiting mechanism and the limiting ring, the sliding rod can switch between the locked position and the unlocked position to achieve contact or separation with the limiting ring. The limiting ring can be fixed on the swing rod, or the limiting ring can only rotate axially relative to the swing rod without moving in other directions. Since the fixed slide rail is fixed on the cover, when the sliding rod contacts the limiting ring, the positions of the sliding rod, the limiting ring, the swing rod, and the cover are relatively fixed, which is suitable for weak earthquakes that will not damage the server rack.

[0031] Specifically, when an earthquake occurs that does not require the server rack's earthquake energy dissipation device to be activated, in order to ensure the stability of the server rack, the sliding rod is pulled to the locking position and abuts against the limiting ring, thereby keeping the cover perpendicular to the ground and maintaining the stability of the device. When a larger earthquake occurs, the sliding rod is driven to the unlocking position, thereby directly activating the earthquake energy dissipation function of the server rack's earthquake energy dissipation device.

[0032] The server rack seismic energy dissipation device provided by this invention is applicable to earthquakes of varying degrees, is easy to operate, and can avoid the problem of unstable connection between servers inside the server rack and external devices caused by minor earthquakes. It is easy to operate, reliable in use, and low in cost.

[0033] In one embodiment, the limiting mechanism, through the arrangement of the second telescopic elastic component and the rope, uses the rope to drive the sliding rod, while the second telescopic elastic component is used to reset the sliding rod. When there is no external force applied to the rope, the sliding rod is in the unlocked position, at which time the server rack seismic energy dissipation device activates its seismic energy dissipation function. When the rope receives an external force, the sliding rod is in the locked position, at which time the server rack seismic energy dissipation device deactivates its seismic energy dissipation function. Simultaneously, by setting up the linkage mechanism, which is connected to the second end of the rope, it is used to pull the rope to move the sliding rod to the locked position. The second telescopic elastic component is used to drive the sliding rod to the unlocked position when the linkage mechanism releases the rope. This design is convenient to operate, low in cost, and reliable in use. Attached Figure Description

Detailed Implementation

[0044] The core of this invention is to provide a server rack earthquake energy dissipation device that is applicable to earthquakes of different magnitudes, ensuring the stability of the server rack, and has high energy dissipation efficiency for larger earthquakes.

[0045] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0046] Please refer to Figure 1 and Figure 2 In this embodiment, the server rack seismic energy dissipation device includes:

[0047] The shock absorption mechanism 3 includes a cover 301, a swing rod 302, a limiting ring 305, and a shock absorption assembly. The cover 301 and the limiting ring 305 are both sleeved on the swing rod 302. The first end of the swing rod 302 extends outside the cover 301 and is connected to the limiting ring 305. The first end of the swing rod 302 is used to install the server rack 6. The shock absorption assembly is installed between the cover 301 and the swing rod 302.

[0048] Limiting mechanism 4, please refer to Figure 5 It includes several fixed slide rails 401 and several slide rods 402. The fixed slide rails 401 are fixedly installed on the cover 301, and the slide rods 402 are movably installed on the fixed slide rails 401. The slide rods 402 can slide to the locked position or the unlocked position.

[0049] When the slide bar 402 is in the locked position, one end of the slide bar 402 abuts against the limiting ring 305 to lock the cover 301; when the slide bar 402 is in the unlocked position, one end of the slide bar 402 separates from the limiting ring 305 to unlock the cover 301, and the cover 301 and the swing bar 302 can swing relative to each other.

[0050] Specifically, the cover 301 is conical, with the smaller diameter end of the cover 301 fitted onto the swing rod 302. The first end of the swing rod 302 is installed at the bottom of the server rack 6 to support and install the server rack 6. The limiting ring 305 can be a separate structural component or an integral structure with the cover 301. Preferably, the limiting ring 305 is machined separately and then installed at the first end of the swing rod 302 for easy replacement and improved reliability.

[0051] The server rack earthquake energy dissipation device, through the setting of the shock absorption mechanism 3, will cause the server rack 6 to shake during an earthquake. The server rack 6 will cause the swing rod 302 in the shock absorption mechanism 3 to deflect. After the swing rod 302 deflects, it will dissipate energy through the shock absorption components, reducing the kinetic energy generated by the earthquake. This allows the device to withstand large vibrations, preventing the server rack 6 from falling apart or being destroyed, and thus effectively protecting the servers inside the server rack 6.

[0052] Meanwhile, the limiting mechanism 4 limits the server rack in the event of a minor earthquake or no earthquake, reducing swaying. The limiting ring 305 is used to switch the sliding rod 402 between locked and unlocked positions, allowing it to engage or disengage. The limiting ring 305 can be fixed to the swing rod 302, or it can only rotate axially relative to the swing rod 302 without moving in other directions. Since the fixed slide rail 401 is fixed to the cover 301, when the sliding rod 402 engages with the limiting ring 305, the positions of the sliding rod 402, the limiting ring 305, the swing rod 302, and the cover 301 are relatively fixed, making it suitable for weak earthquakes that will not damage the server rack 6.

[0053] Specifically, when an earthquake occurs that does not require the server rack's seismic energy dissipation device to be activated, in order to ensure the stability of the server rack 6, the slide bar 402 is pulled to the locked position and abuts against the limit ring 305, thereby keeping the cover 301 perpendicular to the ground and maintaining the stability of the device; when a larger earthquake occurs, the slide bar 402 is driven to the unlocked position, thereby directly activating the seismic energy dissipation function of the server rack's seismic energy dissipation device.

[0054] The server rack earthquake energy dissipation device provided by this invention is applicable to earthquakes of different degrees, is easy to operate, and can avoid the problem of unstable connection between the server inside the server rack and external equipment due to minor earthquakes. It is easy to operate, reliable to use, and low in cost.

[0055] In some embodiments, one end of the swing arm 302 is provided with a counterweight 306, and the other end is provided with a placement platform 304 for placing and connecting the server rack 6. A limiting ring 305 is sleeved on the placement platform 304, and the size of the limiting ring 305 is adapted to the size of the placement platform 304. Specifically, the counterweight 306 can be frustum-shaped, with the larger diameter end located at the second end of the swing arm 302. The setting of the counterweight 306 can ensure that the swing arm 302 is in a vertical state and maintain stability. The placement platform 304 is disc-shaped and has a platform surface for connecting the server rack 6. The side of the placement platform 304 facing away from the platform surface is connected to the limiting ring 305. The limiting ring 305 has an annular mounting groove for the placement platform 304 to be inserted. The placement platform 304 and the main body of the swing rod 302 can be fixed by threaded connection or welding. After the limiting ring 305 and the placement platform 304 are assembled, the placement platform 304 is then installed on the main body of the swing rod 302, which is convenient for processing.

[0056] In some embodiments, the limiting ring 305 has a limiting ring groove on the side near the cover 301, and the slide rod 402 has a pressing block 403 at the end opposite to the fixed slide rail 401. The pressing block 403 is adapted to the shape of the limiting ring groove so that the pressing block 403 abuts against the inner wall of the limiting ring groove. Specifically, the surface of the pressing block 403 opposite to the fixed slide rail 401 is arc-shaped and adapted to the limiting ring groove. In order to ensure the limiting effect of the pressing block 403 on the limiting ring groove, the sum of the lengths of all pressing blocks 403 is the same as the circumference of the limiting ring groove.

[0057] In some embodiments, the swing rod 302 is further provided with a rolling ball 303, which is located between the counterweight 306 and the limiting ring 305, and close to the limiting ring 305. The cover 301 is sleeved between the rolling ball 303 and the limiting ring 305, and the cover 301 can swing relative to the rolling ball 303. Specifically, the cover 301 is provided with a clearance hole, through which the swing rod 302 passes. The clearance hole is located between the counterweight 306 and the placement platform 304. The diameter of the rolling ball 303 is larger than the diameter of the clearance hole, facilitating the rotational connection between the cover 301 and the rolling ball 303.

[0058] In some implementation methods, please refer to Figure 6The shock-absorbing assembly includes several shock-absorbing elastic components 307, which can be springs. One end of each shock-absorbing elastic component 307 is connected to a counterweight 306, and the other end is connected to the inner wall of the cover 301. Each shock-absorbing elastic component 307 is distributed sequentially along the circumference of the counterweight 306. Specifically, the end of the cover 301 with the larger diameter is provided with several cover legs 3011, which extend from the edge of the cover 301. The number of shock-absorbing elastic components 307 is the same as the number of cover legs 3011, and they correspond one-to-one. One end of each shock-absorbing elastic component 307 is connected to the inner wall of the cover leg 3011, and the other end is connected to the counterweight 306 of the swing rod 302. The cover legs 3011 facilitate the installation of the shock-absorbing elastic components 307, reduce the volume of the cover 301, save materials, reduce weight, and improve energy dissipation.

[0059] Furthermore, a plurality of shock-absorbing elastic components 307 arranged in a circular array are fixedly connected to the outer surface of the counterweight 306. For example, the number of shock-absorbing elastic components 307 can be 6-10. The end of each shock-absorbing elastic component 307 away from the counterweight 306 is fixedly connected to the inner wall of the cover 301. A plurality of limiting mechanisms 4 arranged in a circular array are provided on the outside of the cover 301. The number of limiting mechanisms 4 is the same as that of the shock-absorbing elastic components 307, and they correspond one-to-one.

[0060] In some embodiments, the shock-absorbing assembly further includes an arc-shaped sleeve 308, an arc-shaped rod 309, and a first telescopic elastic component 310. The arc-shaped rod 309 and the first telescopic elastic component 310 are both located inside the arc-shaped sleeve 308. One end of the first telescopic elastic component 310 is mounted on the swing rod 302, and the other end is connected to the arc-shaped rod 309. An impact ball 311 is provided at the end of the arc-shaped rod 309 away from the swing rod 302. The impact ball 311 is used to impact the cover 301 when the swing rod 302 swings. Specifically, the outer surface of the swing rod 302 is fixedly connected with a number of circumferentially arrayed arc-shaped sleeves 308. For example, the number of arc-shaped sleeves 308 can be 6-10. The inner wall of each arc-shaped sleeve 308 is slidably connected with an arc-shaped rod 309. One end of each arc-shaped rod 309 is fixedly connected with an impact ball 311. When an earthquake occurs, the swing rod 302 twists, causing the impact ball 311 to impact the inner wall of the cover 301 to dissipate energy. The arc-shaped rod 309 will be damped by the elastic pressure of the first telescopic elastic component 310, thereby further dissipating the kinetic energy generated by the earthquake. Furthermore, each of the arc-shaped rods 309 near the swing rod 302 is fixedly connected to a first telescopic elastic component 310. The number of first telescopic elastic components 310, arc-shaped sleeves 308, and arc-shaped rods 309 are the same and correspond one-to-one. One end of the first telescopic elastic component 310 is fixedly connected to the inner bottom wall of the arc-shaped sleeve 308. After the impact ball 311 hits the inner wall of the cover 301, the arc-shaped rod 309 will retract into the arc-shaped sleeve 308. After the impact ball 311 no longer presses against the inner wall of the cover 301, the arc-shaped rod 309 will be reset by the elastic component pressure of the first telescopic elastic component 310, waiting for the impact ball 311 to hit the inner wall of the cover 301 again.

[0061] In some embodiments, the limiting mechanism 4 further includes a second telescopic elastic component 405 and a rope 406. The second telescopic elastic component 405 is installed inside the fixed slide rail 401. A stop 404 is fixedly connected to the outer surface of the slide rod 402. The second telescopic elastic component 405 is fixedly connected between the stop 404 and the fixed slide rail 401. The stop 404 is located inside the fixed slide rail 401. One end of the slide rod 402 away from the limiting ring 305 is connected to the first end of the rope 406. Specifically, the limiting mechanism 4 uses the second telescopic elastic component 405 and the rope 406 to drive the slide rod 402, while the second telescopic elastic component 405 is used to reset the slide rod 402. When there is no external force on the rope 406, the slide rod 402 is in the unlocked position, at which time the earthquake energy dissipation device of the server rack activates the earthquake energy dissipation function. When the rope 406 receives an external force, the slide rod 402 is in the locked position, at which time the earthquake energy dissipation device of the server rack deactivates the earthquake energy dissipation function. Specifically, when each pressing block 403 presses against the confined annular groove simultaneously, the cover 301 remains perpendicular to the ground, thus maintaining the stability of the device. Furthermore, a second telescopic elastic component 405 is sleeved on the outer surface of the slide rod 402, and a stop block 404 is fixedly connected to the outer surface of the slide rod 402. The second telescopic elastic component 405 is fixedly connected between the stop block 404 and the fixed slide rail 401. When the rope 406 stops pulling the slide rod 402, the slide rod 402 will be reset by the elastic force of the second telescopic elastic component 405, causing the stop block 404 to drive the top pressing block 403 on the slide rod 402 away from the confined ring groove, so that the top pressing block 403 no longer squeezes the confined ring groove. At this time, the slide rod 402 is in the unlocked position. When the rope 406 pulls the slide rod 402, the slide rod 402 will stretch the second telescopic elastic component 405, causing the stop block 404 to drive the top pressing block 403 on the slide rod 402 closer to the confined ring groove, until the stop block 404 abuts against the edge of the fixed slide rail 401. At this time, the top pressing block 403 enters the confined ring groove, and the slide rod 402 is in the locked position.

[0062] In some embodiments, a linkage mechanism 5 is also included. The linkage mechanism 5 is connected to the second end of the rope 406 and is used to pull the rope 406 to move the slide bar 402 to the locked position. The second telescopic elastic member 405 is used to drive the slide bar 402 to the unlocked position when the linkage mechanism 5 releases the rope 406. Specifically, the linkage mechanism 5 can be an electric mechanism, such as a motor driving the rope 406 to wind or release, or it can be other forms. The rope 406 can be a steel rope, which has high strength and reliable use. By setting the linkage mechanism 5, which is connected to the second end of the rope 406, and is used to pull the rope 406 to move the slide bar 402 to the locked position, and the second telescopic elastic member 405 is used to drive the slide bar 402 to the unlocked position when the linkage mechanism 5 releases the rope 406, the operation is convenient, the cost is low, and the use is reliable.

[0063] In some implementation methods, please refer to Figure 3 It also includes a support frame 1, and the cover 301 is mounted on the support frame 1; specifically, the support frame 1 is U-shaped with the opening facing the horizontal direction, the top of the support frame 1 forms a ring-shaped connecting frame 2, and the inner side of the periphery of the connecting frame 2 is provided with several connecting legs 201, the connecting legs 201 are bent, one end of the connecting legs 201 is connected to the connecting frame 2, and the other end is connected to the outer surface of the cover 301.

[0064] Furthermore, the linkage mechanism 5 includes a fixed shaft 501, a slide tube 502, an electric telescopic rod 509, and a locking assembly. The fixed shaft 501 is mounted on the support frame 1, the slide tube 502 is movably sleeved on the fixed shaft 501, and the slide tube 502 is connected to the second end of the rope 406. The locking assembly is connected to the electric telescopic rod 509 and is used to lock or release the slide tube 502 under the drive of the electric telescopic rod 509. Specifically, the fixed shaft 501 is fixedly connected to the inner bottom wall of the support frame 1, and the fixed shaft 501 provides a guiding function for the slide tube 502. The counterweight 306 of the swing rod 302 can be placed on top of the fixed shaft 501.

[0065] In some embodiments, the snap-fit ​​assembly includes a connecting plate 508, at least two hinge rods 507, a limiting sleeve 504, snap-fit ​​posts 505, and a third telescopic elastic component 506. The periphery of the slide tube 502 is provided with a slot. The number of snap-fit ​​posts 505 is the same as the number of slots and they correspond one-to-one. When the snap-fit ​​post 505 is inserted into the slot, it locks the slide tube 502. When the snap-fit ​​post 505 is dislodged from the slot, it releases the slide tube 502. Specifically, the inner bottom wall of the support frame 1 is fixedly connected with a number of limiting sleeves 504, which can be two. The limiting sleeves 504 are square sleeves. The inner walls of the two limiting sleeves 504 are slidably connected with snap-fit ​​posts 505. The outer surface of the slide tube 502 is provided with slots that are adapted to the snap-fit ​​posts 505 and are the same number. After each snap-fit ​​post 505 snaps and limits the slide tube 502, it limits and locks the slide tube 502, so that the slide tube 502 is kept at the bottom of the fixed shaft 501.

[0066] Specifically, the first telescopic elastic component 310, the second telescopic elastic component 405, and the third telescopic elastic component 506 are all preferably springs, which are easy to source, easy to install, and have good elasticity.

[0067] In some implementation methods, please refer to Figure 4The limiting mechanism 4 also includes a first roller 407 and a second roller 408. The first roller 407 is mounted on the cover 301 and is positioned close to the fixed slide rail 401. The second roller 408 is mounted on the edge of the cover 301 away from the limiting ring 305. The rope 406 passes from the end of the slide rod 402, passes around the first roller 407 and the second roller 408 in sequence, and is connected to the slide tube 502. Specifically, the number of limiting mechanisms 4 is the same as the number of cover legs 3011, and they correspond one-to-one. That is, the limiting mechanisms 4 are mounted on the cover 301 at positions corresponding to the cover legs 3011. This arrangement is to facilitate the setting of the second roller 408. Each limiting mechanism 4 includes a first roller 407, a second roller 408, a fixed slide rail 401, and a slide rod 402, and the limiting mechanisms 4 are evenly distributed along the circumference of the cover 301. Furthermore, a rope 406 is fixedly connected to one end of the slide rod 402 away from the top pressing block 403, and a first roller 407 is fixedly connected to the outer surface of the fixed slide rail 401. The rope 406 is connected to the first roller 407 in a transmission connection. A second roller 408 is fixedly connected to the outer surface of the cover 301. The rope 406 is connected to the second roller 408 in a transmission connection. When the slide tube 502 drags the rope 406 downward, after transmission through the second roller 408 and the first roller 407, the rope 406 will drag the slide rod 402 to make the top pressing block 403 press against the restricted annular groove.

[0068] Furthermore, one side of the connecting plate 508 is connected to the electric telescopic rod 509, and the other side is hinged to a hinge rod 507 at each end. The side of the hinge rod 507 away from the connecting plate 508 is hinged to the locking post 505. The locking post 505 and the third telescopic elastic component 506 are both located inside the limiting sleeve 504. The electric telescopic rod 509 can push the connecting plate 508 to move, thereby pushing each hinge rod 507 to separate. The hinge rod 507 drives the locking post 505 to move and compress the third telescopic elastic component 506. The locking post 505 releases the slide tube 502. When the slide tube 502 is released, that is, when the linkage mechanism 5 releases the rope 406, the second telescopic elastic component 405 drives the slide rod 402 to move to the unlock position, thereby releasing the limit on the limiting ring 305. At this time, the shock absorption mechanism 3 will dissipate the vibration of the server rack 6 and reduce the damage to the server rack 6 caused by the earthquake. Specifically, the outer surface of each snap-fit ​​post 505 is fixedly connected to a third telescopic elastic component 506. The end of each third telescopic elastic component 506 away from the fixed shaft 501 is fixedly connected to the corresponding limiting sleeve 504. The outer surface of each snap-fit ​​post 505 is hinged to the hinge rod 507 through a pin. Through the setting of the third telescopic elastic component 506, the snap-fit ​​post 505 bears the elastic component pressure of the third telescopic elastic component 506, so that the snap-fit ​​post 505 maintains the snap-fit ​​state to the slide tube 502. Furthermore, the inner bottom wall of the support frame 1 is fixedly connected to an electric telescopic rod 509. The telescopic end of the electric telescopic rod 509 is provided with a connecting plate 508. One end of each hinge rod 507 is hinged to the connecting plate 508 through a pin.

[0069] Furthermore, the locking post 505 is provided with a guide slope. When the slide tube 502 moves toward the locking post 505, the slide tube 502 abuts against the guide slope of the locking post 505, thereby pushing the locking post 505 to compress the third telescopic elastic component 506. When the locking post 505 enters the locking slot, the third telescopic elastic component 506 drives the locking post 505 to reset, facilitating operation. It also includes a pedal 503, which is installed on the slide tube 502 and used to drive the slide tube 502 to slide toward the locking post 505. Specifically, each rope 406 is fixedly connected to the outer surface of the slide tube 502, and a pedal 503 is fixedly connected to the outer surface of the slide tube 502. The outer surface of the pedal 503 is provided with anti-slip texture, making it convenient for workers to step on the pedal 503 to move the slide tube 502 downwards, saving time and effort.

[0070] In some implementations, it also includes:

[0071] Seismograph 510, used to detect earthquake magnitude;

[0072] The controller, connected to the seismograph 510 and the electric telescopic rod 509, is used to control the electric telescopic rod 509 to lock or release the slide tube 502 when the earthquake level reaches a preset level.

[0073] Specifically, it may also include a judgment module connected to the controller. When the seismograph 510 detects an earthquake level, it sends the earthquake level to the judgment module. The judgment module judges whether the earthquake level has reached a preset level and sends the judgment result to the controller. The controller then determines whether to drive the slide rod 402 based on the judgment result of the judgment module. Specifically, when the earthquake level reaches the preset level, the slide tube 502 is released by controlling the linkage mechanism 5. The release of the slide tube 502 is specifically achieved by controlling the electric telescopic rod 509. When the earthquake level reaches the preset level, the controller controls the electric telescopic rod 509 to retract. The electric telescopic rod 509 no longer locks the slide tube 502, but releases the slide tube 502. Then the slide rod 402 of the locking mechanism can disengage from the limiting ring 305 and move to the unlocked position. Of course, the locking or releasing of the slide tube 502 can also be achieved in other ways. For example, the electric telescopic rod 509 can be directly inserted into the slot of the slide tube 502 to directly lock or release the slide tube 502.

[0074] Furthermore, a seismograph 510 is installed on the inner wall of the support frame 1. The seismograph 510 is compatible with the electric telescopic rod 509. In the event of a large earthquake, the seismograph 510 will detect the earthquake and activate the electric telescopic rod 509. The electric telescopic rod 509 will press against the connecting plate 508, causing each hinge rod 507 to drive the corresponding locking post 505 away from each other, so that each locking post 505 cancels the locking of the slide tube 502. At this time, the rope 406 no longer drags the slide rod 402.

[0075] In some embodiments, a pressure sensor is also included. The pressure sensor is connected to the controller and is installed within the confined ring groove of the confined ring member, or on the surface of the top pressure block 403 near the confined ring groove. The pressure sensor monitors whether the top pressure block 403 has entered the confined ring groove and sends a position signal to the controller when the top pressure block 403 enters the confined ring groove. The controller issues an alarm signal when the earthquake magnitude does not reach a preset level and no position signal is received from the pressure sensor. A warning component is also included, connected to the controller, and emits an audible or visual signal upon receiving the alarm signal. Specifically, the warning component can be a buzzer or a warning light. The aforementioned pressure sensor configuration ensures that the top pressure block 403 enters the confined ring groove when the seismic energy dissipation function of the device is not activated, thereby guaranteeing the stability of the server rack 6 and improving its reliability. Furthermore, when the earthquake level reaches a preset level, i.e., when the seismic energy dissipation function of the device needs to be activated, the controller is also used to issue an alarm signal upon receiving the positioning signal from the pressure sensor. At this time, if the seismic energy dissipation function of the device needs to be activated, the slide bar 402 should be in the unlocked position. If the controller can still receive the positioning signal from the pressure sensor, it indicates that the slide bar 402 has not moved, and the staff should be reminded to check to ensure that the top pressure block 403 smoothly leaves the confined ring groove, thereby reducing damage caused by the earthquake.

[0076] This invention incorporates a shock-absorbing mechanism 3. In the event of an earthquake, the server rack 6 will shake, causing the swing arm 302 to deflect. After deflection, the swing arm 302 is damped by the pressure of multiple shock-absorbing elastic components 307, reducing the kinetic energy generated by the earthquake. Simultaneously, when the swing arm 302 twists, the impact ball 311 will strike the inner wall of the cover 301, and the arc-shaped rod 309 will be damped by the pressure of the first telescopic elastic component 310, further dissipating the kinetic energy generated by the earthquake. This allows the device to withstand significant tremors, preventing the network server rack 6 from disintegrating or being damaged, thus effectively protecting the servers inside the server rack 6. By setting the limiting mechanism 4, in the event of a weak earthquake that will not damage the server rack 6, it is not necessary to activate the energy dissipation device. Therefore, it is necessary to maintain the stability of the server rack 6 on the enclosure 301. By pulling the slide tube 502 downward and pulling the rope 406, the rope 406 pulls the slide bar 402, causing the top pressure block 403 to enter the confined ring groove. This allows each top pressure block 403 to simultaneously press against the confined ring groove, keeping the enclosure 301 perpendicular to the ground and maintaining the stability of the device. In the event of a larger earthquake, the seismograph 510 will detect the earthquake and activate the electric telescopic rod 509, causing each locking post 505 to release its locking to the slide tube 502, thus directly activating the seismic energy dissipation function of the device.

Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this invention. It should be noted that those skilled in the art can make various improvements and modifications to this invention without departing from its principles, and these improvements and modifications also fall within the protection scope of this invention.
