Description

Technical Field

[0001] This utility model relates to the field of computer chassis technology, specifically to an adjustable height computer chassis bracket. Background Technology

[0002] As an important carrier of computer hardware, the computer case plays a role in protecting internal components and assisting in heat dissipation. It is widely used in various office, production and entertainment scenarios. With the deepening of ergonomics concepts and the diversification of usage scenarios, users have put forward higher requirements for the placement height and installation stability of computer cases. Traditional fixed-height case brackets can no longer meet the personalized needs of different users in terms of sitting posture, space layout and other aspects.

[0003] Most computer chassis brackets on the market are fixed structures, which cannot flexibly adjust the height of the chassis according to factors such as the user's height and workbench height. Long-term use can easily lead to neck and shoulder fatigue, affecting work efficiency and physical health. At the same time, traditional brackets have a single way of fixing the chassis and lack self-adaptive clamping function, making it difficult to adapt to chassis of different sizes. During equipment operation, the chassis is prone to displacement due to vibration, which not only affects the user experience but may also cause internal wiring to loosen, increasing the risk of hardware failure. To address this, we have proposed a height-adjustable computer chassis bracket. Utility Model Content

[0027] Structural Description: Computer chassis 1: As the main body to be supported, it is placed between chassis support plate 9 and cover plate 15 and is firmly fixed by clamping components; Chassis Bracket 2: The basic structure, with a top integrated support plate, transmission module and clamping components, supports and adjusts the computer chassis; Lifting cylinder 3: connects the chassis support plate 9 and the transmission structure, and achieves lifting by linkage between the mounting column 19 and the threaded bushing 4; Threaded bushing 4: Fitted onto threaded screw 5, and engaged with the mounting post of lifting cylinder 3, converting the rotation of the screw into linear lifting motion; Threaded screw 5: Located in the guide groove 17 of the fixed frame 16, it cooperates with the threaded bushing 4 to provide the core transmission for height adjustment; First bevel tooth 6: connects to the top of the threaded screw 5, meshes with the second bevel tooth 7, and transmits the rotational power of the drive shaft 8; The second bevel tooth 7 is fitted onto the drive shaft 8 and engages with the first bevel tooth 6. Their symmetrical distribution ensures synchronous drive of the lead screws on both sides.

Chassis support plate 9: Supports the computer chassis, with lifting cylinder 3 connected to the right end, and support bar 20 and clamping components on the left side; Storage strip 10: L-shaped structure, with the end inserted into the storage frame 21, and a built-in clamping spring 11, which works with the telescopic strip 12 to clamp the chassis; Clamping spring 11: Installed at the ends of storage bar 10 and telescopic bar 12, it generates elastic force when compressed to achieve self-adaptive clamping of the chassis; Telescopic strip 12: L-shaped, with the end inserted into the storage box 21 and the front end inserted into the storage strip 10, and is tightly attached to the chassis by spring force; Adjusting bar 13: Inserted into the support bar 20, with a top cover plate 15 and an inner telescopic spring 14 to assist in stabilizing the support; Telescopic spring 14: Located inside the adjusting bar 13, it provides elastic cushioning when the cover plate 15 is raised or lowered, ensuring stable placement; Cover plate 15: clamps the chassis with the chassis support plate 9, and has a storage frame 21 on the back for installing and fixing the clamping components; Fixed bracket 16: symmetrically fixed to the top of the bracket, with an internal guide groove 17 to support the movement of the guide screw and the mounting column; Guide groove 17: runs through the fixed frame 16, providing a movement track for the threaded screw 5 and the mounting column 19 to ensure accurate lifting; Fixed frame 18: Fixed to the top of the fixed bracket 16, it accommodates the drive assembly components and provides mounting support for the drive shaft 8 and the bevel gear; Mounting column 19: Fixed to both ends of the lifting cylinder 3, inserted into the guide groove 17, and engaged with the threaded bushing 4 to achieve linkage lifting; Support bar 20: Symmetrically arranged on the left side of support plate 9, with internal receiving bar 10, providing support and guidance for adjustment bar 13; Storage frame 21: fixed to the back of support plate 9 and cover plate 15, with an internal telescopic groove for installing storage clamping components.

[0028] Working principle: When the height of the computer chassis 1 needs to be adjusted, the operator rotates the rings at both ends of the drive shaft 8. The drive shaft 8 rotates, causing the symmetrically distributed second bevel teeth 7 on its cylindrical surface to rotate. Since the second bevel teeth 7 mesh with the first bevel teeth 6, the first bevel teeth 6 rotate accordingly. The end of the first bevel teeth 6 is fixedly connected to the top of the threaded screw 5, so the threaded screw 5 starts to rotate. The threaded screw 5 is set in the guide groove 17 inside the fixed frame 16, and interacts with the threaded bushing 4 that is sleeved on it and threadedly engaged. As the threaded screw 5 rotates, the threaded bushing 4 will move linearly along the threaded screw 5. Because the mounting posts 19 at both ends of the lifting cylinder 3 are set in the guide groove 17, and the threaded bushing 4 is snapped and fixed in the mounting holes of the mounting posts 19, the linear movement of the threaded bushing 4 causes the lifting cylinder 3 to rise or fall, thereby causing the chassis support plate 9 fixed on the lifting cylinder 3 to achieve height adjustment. The top of the adjusting bar 13 is fixedly connected to the cover plate 15 by bolts, thereby causing the cover plate 15 to move in the vertical direction, realizing the adjustment of the computer chassis height. The height of the computer chassis 1 is adjusted. Simultaneously, the adjustable strip 13, inserted into the symmetrically distributed support strips 20 on the top left side of the chassis support plate 9, has a telescopic spring 14 at its inner bottom end. This provides elastic support when the cover plate 15 is raised or lowered, ensuring stability during adjustment and placement. When the computer chassis 1 is placed between the chassis support plate 9 and the cover plate 15, the clamping assembly begins to function. The clamping assembly consists of a storage strip 10, a clamping spring 11, and a telescopic strip 12. The end of the storage strip 10 is inserted into the back of the chassis support plate 9 for storage. Inside the telescopic groove of the frame 21, the end of the telescopic strip 12 is inserted into the telescopic groove inside the storage frame 21 on the back of the cover plate 15, and the front end of the telescopic strip 12 is inserted into the storage strip 10. When the computer case 1 is placed, the telescopic strip 12 is squeezed, and the clamping spring 11 is compressed. Using the elastic force of the clamping spring 11, the telescopic strip 12 and the storage strip 10 are pressed tightly against both sides of the computer case 1, thereby firmly clamping the computer case 1 and preventing it from shaking on the bracket, ensuring the stability and safety of the computer case 1 during use.
