[0029] Embodiment 1:

[0030] As Figures 1 to 3 shown, a pull-out variable-volume computer case proposed by the present utility model includes: a first case 1, and the first case 1 is arranged in a "C" shape. A heat dissipation plate 2 is fixedly arranged on one side of the first case 1 to facilitate the heat dissipation of various components installed inside the first case 1; a set of guide rails 3 fixedly arranged on the inner side of the first case 1, a guide block 4 is slidably arranged on the guide rails 3, and one end of the guide block 4 is fixedly provided with a second case 5, and the second case 5 is arranged in a "C" shape to facilitate the horizontal sliding of the second case 5 inside the first case 1. A fixing plate 6 is fixedly arranged on one side of the second case 5; a cover plate assembly 7 clamped on one side of the first case 1 for limiting the second case 5 is provided to facilitate the limiting and fixing after adjusting the first case 1 and the second case 5. A limiting assembly 8 for limiting the cover plate assembly 7 is arranged at the upper end of the first case 1, which can stably limit the cover plate assembly 7 and prevent it from moving.

[0031] As Figure 1 、 Figure 4 and Figure 5 shown, the cover plate assembly 7 includes a frame 71, a chute 72 is opened on the frame 71, a slider 73 is slidably arranged inside the chute 72, and a side plate 74 is fixedly arranged between the sliders 73 to facilitate the guiding of the side plate 74 and make the side plate 74 slide horizontally stably. A connecting seat 75 is fixedly arranged on one side of the side plate 74, a threaded rod 76 is fixedly arranged on one side of the frame 71, a set of first telescopic rods 77 is movably sleeved on the outer wall of the threaded rod 76, and one end of the first telescopic rod 77 is rotatably connected to the side plate 74 to facilitate the movement of the side plate 74. A limiting threaded nut 78 is threadedly sleeved on the outer wall of the threaded rod 76, which can limit the first telescopic rod 77 and facilitate the adjustment of the position of the side plate 74.

[0032] Furthermore, a plurality of clamping blocks 9 are fixedly arranged on one side of the first case 1, a plurality of corresponding clamping grooves 10 are opened on one side of the frame 71, and the clamping blocks 9 can be stably clamped with the clamping grooves 10, so that the cover plate assembly 7 is stably installed on one side of the first case 1, and the first case 1 and the second case 5 are sealed after the adjustment of the space.

[0033] Secondly, a slot 11 is provided on one side of the fixing plate 6, and a corresponding insert block 12 is fixedly provided on one side of the side plate 74, which enables the side plate 74 to be stably engaged with the second chassis 5, thereby stably limiting the position of the side plate 74.

[0034] In addition, the snap-fit ​​block 9 is designed with an "L" shape, which allows the snap-fit ​​block 9 to be stably snapped into the snap-fit ​​slot 10, making it easy to install and remove.

[0035] The working principle of this embodiment is as follows: When adjusting the volume of the computer case, the limit thread cap 78 is manually loosened from the threaded rod 76, pushing the side plate 74. The side plate 74 drives the slider 73 to slide horizontally in the slide groove 72. At the same time, the side plate 74 drives the first telescopic rod 77 to retract or extend through the connecting seat 75. One end of the first telescopic rod 77 rotates on the threaded rod 76.

[0036] While pushing the side plate 74 to move, the side plate 74 drives the fixing plate 6 to move horizontally through the insert block 12 and the slot 11. The fixing plate 6 drives the second chassis 5 to move horizontally. The second chassis 5 drives the guide block 4 to slide in the guide rail 3, so that the second chassis 5 slides horizontally stably.

[0037] Once the second chassis 5 is moved to the appropriate position, manually tighten the limiting thread cap 78 onto the threaded rod 76. The limiting thread cap 78 applies pressure to the first telescopic rod 77, causing the first telescopic rod 77 to be limited. The first telescopic rod 77 limits the side plate 74 through the connecting seat 75, thereby allowing the computer chassis to quickly adjust its volume, saving space and facilitating computer upgrades and expansions.

[0038] Example 2:

[0039] like Figures 1 to 3 As shown, based on Embodiment 1, the limiting component 8 includes two sets of second telescopic rods 81. One end of the second telescopic rod 81 is fixedly connected to the first housing 1, and the other end of the second telescopic rod 81 is fixedly provided with a locking block 82, which facilitates the stable horizontal movement of the locking block 82. A spring 83 is sleeved on the outer wall of the second telescopic rod 81. One end of the spring 83 is fixedly connected to the first housing 1, and the other end of the spring 83 is fixedly connected to the locking block 82, which facilitates the stable locking of the locking block 82 with the frame 71, thereby stably limiting the frame 71.

[0040] Furthermore, a slot 13 is provided on one side of the frame 71, and the slot 13 can engage with the spring 83, thereby stably limiting the cover assembly 7 to one side of the first housing 1 and sealing the first housing 1.

[0041] The working principle of this embodiment is as follows: When the cover plate assembly 7 is disassembled, the limiting thread cap 78 is manually loosened from the threaded rod 76, pushing the side plate 74 to drive the slider 73 to move out of the slide groove 72. At the same time, the side plate 74 drives the fixing plate 6 to move horizontally through the insert block 12 and the slot 11. The fixing plate 6 drives the guide block 4 to move out of the guide rail 3 through the second housing 5, thereby removing the second housing 5 and the side plate 74.

[0042] Then, push the locking block 82 to move horizontally out of the locking slot 13. The locking block 82 drives the second telescopic rod 81 to retract. At the same time, the locking block 82 pushes the spring 83 to retract. Then, push the frame 71 vertically upward to move vertically upward, so that the locking slot 10 on the frame 71 moves out of the locking block 9, thereby disassembling the frame 71, which facilitates the disassembly and assembly of the internally installed components and improves maintenance efficiency.

[0043] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
