[0026] Example:

[0027] Reference Figure 1-Figure 6A push-in and pull-out device for a server chassis comprises a slide rail 1, an outer wall of which is symmetrically slidably connected with a mounting frame 2, and further comprises:

[0028] A clamping height adjustment component, the clamping height adjustment component includes a bidirectional screw rod 4 rotatably connected to the inner wall of the mounting frame 2, the outer wall of the bidirectional screw rod 4 is symmetrically threadedly connected with a T-block 6, and the T-block 6 is slidably connected to the mounting frame 2, and a knob 5 is fixedly connected to the top wall of the bidirectional screw rod 4. The knob 5 is held and rotated, thereby driving the bidirectional screw rod 4 to rotate in the mounting frame 2, and the threads of the bidirectional screw rod 4 and the T-block 6 cooperate, so that the T-block 6 is close to each other or moves relatively in the mounting frame 2, that is, the clamping box 7 and the clamping plate 20 inside the clamping box 7 are driven to move synchronously, thereby clamping the server chassis structure;

[0029] A driving height adjustment component includes a clamping box 7 fixedly connected to the outer wall of the T-block 6, a slide plate 8 is slidably connected to the inner wall of the clamping box 7, a card block 9 is slidably connected to the inner wall of the slide plate 8, a telescopic rod 10 is fixedly connected to the outer wall of the card block 9, and a concave frame 12 is fixedly connected to the end of the telescopic rod 10 away from the slide plate 8. A spring 11 is sleeved on the outer wall of the telescopic rod 10, and the spring 11 is fixedly connected to the card block 9. A rotating rod 13 is rotatably connected to the inner wall of the concave frame 12. By toggling the rotating rod 13, the concave frame 12 is driven to move, and then the telescopic rod 10 and the slide plate 8 are driven to slide in the clamping box 7, thereby driving the card block 9 to move. The surface and the inner wall of the card slot 18 are both arc-shaped structures. When the card block 9 moves, it will squeeze the surface of the card slot 18. When the force of the card block 9 inserted into the card slot 18 is less than the thrust, it will shrink toward the position of the telescopic rod 10, thereby moving out of the card slot 18. At this time, the spring 11 stores elastic energy until the card block 9 moves to the position of the designated card slot 18. The elastic energy stored is released by the spring 11 to push the card block 9 to re-enter the designated card slot 18 position. At this time, the gear 14 follows the concave frame 12 to move to the horizontal position of the corresponding card slot 18. The outer wall of the rotating rod 13 is fixedly connected with the gear 14. The gear 14 is used to drive the rack 21 to mesh and drive the clamping plate 20 to move;

[0030] The thickness adjustment component is arranged on the inner wall of the clamping box 7, and the thickness adjustment component cooperates with the driving height adjustment component.

[0031] Reference Figure 4 , Figure 5 and Figure 6The thickness adjustment component includes a slide groove 17 opened on the inner wall of the clamping box 7, and the slide groove 17 is evenly distributed in three to five groups. The inner wall of the slide groove 17 is slidably connected with a slider 19, and the end of the slider 19 away from the slide groove 17 is fixedly connected with a clamping plate 20, and the end of the clamping plate 20 away from the slider 19 is fixedly connected with a rack 21, and the rack 21 is meshed with the gear 14. The rotating rod 13 is rotated to drive the gear 14 to rotate, and the corresponding rack 21 is moved through the meshing transmission of the gear 14, so that the clamping plate 20 follows the rack 21 to slide inside the slide groove 17 through the slider 19, so as to realize the position adjustment of the clamping plate 20, and each clamping plate 20 can be adjusted separately.

[0032] Reference Figure 3 and Figure 6 The inner wall of the clamping box 7 is threadedly connected with a one-way screw 15, and the outer wall of the one-way screw 15 is fixedly connected with a limiting tooth block 16, and the outer wall of the limiting tooth block 16 is against the outer wall of the rack 21. The one-way screw 15 is rotated so that the one-way screw 15 and the clamping box 7 are threadedly matched, so that the limiting tooth block 16 moves and is stuck in all the racks 21, thereby realizing the limitation of the clamping plate 20.

[0033] Reference Figure 3 , Figure 4 and Figure 6 The outer wall of the clamping box 7 is provided with evenly distributed card slots 18, and the card block 9 is located on the inner wall of the card slot 18. The card block 9 is inserted into the card slot 18 to limit the position of the telescopic rod 10, the concave frame 12, the rotating rod 13 and the gear 14.

[0034] Reference Figure 1 A handle 3 is fixedly connected to the outer wall of the slide rail 1. The slide rail 1 is moved by pulling the handle 3, thereby driving the mounting frame 2, the T-block 6, the clamping box 7 and the clamping plate 20 inside the clamping box 7 to move, and then the structure of the clamped server chassis is pulled out.

[0035] Specifically, when the push-and-pull device of the server chassis is working / in use: first, according to the size of the installation gap of the server chassis, the concave frame 12 is driven to move by toggling the rotating rod 13, and then the telescopic rod 10 and the slide plate 8 are driven to slide in the clamping box 7, thereby driving the block 9 to move. The surface of the block 9 and the inner wall of the slot 18 are both arc-shaped structures. When the block 9 moves, it will squeeze the surface of the slot 18. When the force of the block 9 inserted into the slot 18 is less than the thrust, it will shrink toward the position of the telescopic rod 10, thereby moving out of the slot 18. At this time, the spring 11 elastically stores energy until the block 9 moves to the position of the designated slot 18, and the spring 11 releases the elastic energy to push the block 9 to re-enter the designated slot 18 position. At this time, the gear 14 follows the concave frame 12 to move to the corresponding horizontal position of the slot 18. At this time, the rotating rod 13 is rotated to drive the gear 14 to rotate, and the gear 14 is meshed with the corresponding rack 21. After the adjustment is completed, it is only necessary to rotate the one-way screw 15 so that the one-way screw 15 and the clamping box 7 are threadedly matched, so that the limiting tooth block 16 moves and is stuck on all the racks 21, that is, the clamping plate 20 is limited, and then the clamping structure composed of the adjusted clamping plate 20 is inserted into the gap, and then the knob 5 is held and rotated, thereby driving the bidirectional screw 4 to rotate in the mounting frame 2, and the bidirectional screw 4 and the T-block 6 are threadedly matched, so that the T-block 6 is close to or relatively moved in the mounting frame 2, that is, the clamping box 7 and the clamping plate 20 inside the clamping box 7 are driven to move synchronously, thereby clamping the server chassis structure, and finally the handle 3 is held and the slide rail 1 is pulled.
