[0021] See also Figure 1-5The present invention provides a technical solution for the earthquake-resistant device of a data center cabinet: it includes an outer shell 1, an inner shell 2 and a buffer groove 5. The inner shell 2 is movably provided inside the outer shell 1, and a buffer groove 5 is formed between the outer shell 1 and the inner shell 2. The inner top wall and bottom surface of the outer shell 1 are provided with slide grooves 7. The top and bottom of the inner shell 2 are fixedly welded with movable plates 6. The movable plates 6 are fixedly installed with sliders 8 extending into the interior of the slide groove 7 at both ends of the side away from the inner shell 2. The slider 8 is placed inside the slide groove 7 and is slidably connected to its inner wall. A partition 9 is fixedly installed in the middle of the slide groove 7. The slider 8 is close to the partition. A first shock-absorbing cylinder 10 is provided on one side of the plate 9, and a first cavity 13 is opened inside the first shock-absorbing cylinder 10. A first air hole 12 is provided at one end of the interior of the first cavity 13. A first piston 14 is slidably and sealedly connected to the interior of the first cavity 13. One side of the first piston 14 is fixedly connected to a first telescopic rod 11 extending to the outside. The outer end of the first telescopic rod 11 is fixedly connected to the partition 9, and first shock-absorbing springs 15 are provided at both ends of the partition 9. The first shock-absorbing spring 15 is sleeved on the outer periphery of the first shock-absorbing cylinder 10 and the first telescopic rod 11, and the two ends are fixedly connected to the partition 9 and the slider 8 respectively.
[0022] Specifically, a second shock-absorbing cylinder 16 is fixedly installed on the inner walls on both sides of the inner portion of the outer shell 1, a second cavity 17 is opened inside the second shock-absorbing cylinder 16, a second shock-absorbing spring 20 is arranged inside the second cavity 17, and a second piston 22 is also slidably and sealedly arranged inside the second cavity 17. A second telescopic rod 18 is provided on one side of the second piston 22, one end of the second telescopic rod 18 extends to the outside of the second shock-absorbing cylinder 16 and is slidably connected thereto, and a second air hole 21 communicating with the outside is provided at one end of the interior of the second cavity 17.
[0023] Specifically, a corrugated rubber sleeve 4 is provided at the opening of the buffer groove 5. The outer periphery of the corrugated rubber sleeve 4 is fixedly connected to the inner wall of the outer shell 1 by gluing, and the inner ring of the corrugated rubber sleeve 4 is fixedly connected to the outer periphery of the inner shell 2 by gluing.
[0024] Specifically, a rubber pad 19 is fixed to the end of the second telescopic rod 18 by gluing, and the rubber pad 19 does not contact the outer wall of the inner shell 2 .
[0025] Specifically, a mounting plate 3 is provided inside the inner shell 2 , and the mounting plate 3 is fixedly installed inside the inner shell 2 by welding.
[0026] Specifically, a reinforcement base 23 is provided at the bottom of the outer shell 1 , and the reinforcement base 23 is fixedly installed on the bottom of the outer shell 1 by welding.
[0027] In this embodiment, during use, when the outer shell 1 vibrates or impacts, the vibration is transmitted to the inside of the buffer groove 5, causing the slider 8 to displace inside the slide groove 7. The slider 8 applies pressure to the first shock-absorbing cylinder 10, causing the first piston 14 inside the first shock-absorbing cylinder 10 on both sides of the partition 9 to slide inside the first shock-absorbing cylinder 10, thereby driving the first telescopic rod 11 to extend and retract. Due to the sliding of the first piston 14, the space inside the first cavity 13 changes, resulting in a change in the air pressure in the first cavity 13, and air is discharged or inhaled from the first air hole 12. Due to the small aperture of the first air hole 12, air cannot be discharged or inhaled quickly, thereby forming a certain resistance to the movement of the second piston 14, and then cooperating with the first shock-absorbing spring 15 to alleviate the displacement effect of vibration or impact on the movable plate 6 and the inner shell 2. To achieve the purpose of alleviating the vibration amplitude, when the vibration amplitude subjected to the movable plate 6 and the inner shell 2 is large, the displacement amplitude of the inner shell 2 increases, so that the two sides of the outer side of the inner shell 2 are alternately released from the rubber pads 19, and the second telescopic rod 18 is pressed by the rubber pads 19, so that it pushes the second piston 22 to move inside the second cavity 17, and pressurizes the second shock-absorbing spring 20, while compressing the air in the second cavity 17 so that it is slowly discharged from the second air hole 21, so as to achieve the purpose of buffering and shock absorption. When the inner shell 2 is displaced to the maximum distance caused by the vibration, the second shock-absorbing spring 20 pushes the second piston 22 to reset, and then cooperates with the slow suction of the second air hole 21, so that the second telescopic rod 18 pushes the inner shell 2 to slowly reset, thereby reducing the frequency of the vibration displacement of the inner shell 2, achieving the purpose of buffering and shock absorption, and improving its seismic performance.
