Description

Technical Field

[0001] This utility model relates to the field of chassis sheet metal, and more specifically, to a fixing mechanism for chassis sheet metal parts. Background Technology

[0002] Sheet metal parts are a comprehensive cold working process for thin metal sheets, including shearing, punching / cutting / combined cutting, bending, welding, riveting, splicing, forming, etc. Sheet metal parts are characterized by light weight, high strength, electrical conductivity, and low cost, and are widely used in fields such as electronics, electronic communications, automotive industry, and medical devices. For example, sheet metal parts are an essential component in computer cases, mobile phones, and so on.

[0003] The utility model patent with authorization announcement number CN221595600U discloses a fixing mechanism for a chassis sheet metal part, belonging to the field of sheet metal part technology. The mechanism includes a fixing mechanism, which includes a plug-in shell. The outer wall of the plug-in shell is connected to a limiting block that inserts into a limiting groove. A semi-circular block is rotatably connected to the outer wall of the plug-in shell near the second mounting hole. The semi-circular block rotates outward and is locked onto the outer wall of the internal sheet metal part. A rotating disk drives a rotating rod to rotate, which, in conjunction with the meshing of the gear column and the gear shaft, causes the semi-circular block to be housed inside the semi-circular groove. The elastic force of the return spring causes a sliding rod to insert into the plug-in hole, inserting the plug-in shell into the second mounting hole. The limiting block is inserted into the limiting groove. Pushing the push block causes the sliding rod to be pulled out from the plug-in hole. The rotational force of the torsion spring shaft causes the rotating rod to drive the gear column to rotate, which, in conjunction with the meshing of the gear column and the gear shaft, causes each semi-circular block to unfold outward and fit against the inner wall of the sheet metal part on each splicing piece.

[0004] In the above-disclosed structure, the sheet metal is positioned by inserting the outer shell and using internal prying blocks and other structures. This not only makes the structure complex and difficult to fix during production, but also makes it inconvenient to quickly insert and remove the sheet metal for positioning. It has poor adaptability and is not conducive to installing other components after positioning. Therefore, it needs to be improved. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a fixing mechanism for a chassis sheet metal part.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1 , Figure 3 , Figure 5 and Figure 6A fixing mechanism for a chassis sheet metal part includes a chassis body 1. A U-shaped positioning ring 11 is fixedly connected to one side of the interior of the chassis body 1. A sheet metal body 12 is snapped onto the upper end of the U-shaped positioning ring 11. The surface of the sheet metal body 12 is provided with a mounting groove 13, through which other components can be hung, facilitating installation and use. The sheet metal body 12 is positioned on one side of the interior of the chassis body 1 and can be separately inserted for easy installation and disassembly, facilitating fixed use. A spherical positioning head 14 is fixedly welded to the inner side of the U-shaped positioning ring 11, and a positioning head 15 is fixedly welded to the lower end surface of the sheet metal body 12. The positioning head 15 can be inserted into the U-shaped positioning ring 11, with two separate insertion positions, facilitating separate installation, and providing high efficiency and stability. Attached to the inside of the U-shaped positioning ring 11, one end of the positioning head 15 is provided with an elastic plate 16. An elastic ball head 17 is fixedly connected to one side surface of the elastic plate 16. The elastic ball head 17 is snapped into one side surface of the spherical positioning head 14. An arc-shaped support plate 18 is fixedly welded to one side surface of the sheet metal body 12. The arc-shaped support plate 18 is elastically pressed against the inner wall of the chassis body 1, which can support and assist positioning, making it convenient and stable. One end of the arc-shaped support plate 18 is provided with a free end 19. The free end 19 can leave a gap for the elastic deformation of the arc-shaped support plate 18, avoiding interference, facilitating assembly positioning, and ensuring high efficiency and stability. A gap is left between the free end 19 and the sheet metal body 12. One side surface of the arc-shaped support plate 18 is pressed against and connected to the inner wall surface of the chassis body 1.

[0028] Please see Figure 2 and Figure 4 A fixing block 2 is fixedly connected to the upper inner side of the chassis body 1. A right-angle rod 21 is rotatably installed on one end of the fixing block 2. One end of the right-angle rod 21 is snapped onto one end surface of the sheet metal body 12 and is located in the middle of the upper end of the sheet metal body 12. A rotating head 22 is fixedly connected to one end of the fixing block 2. The rotating head 22 is rotatably connected to the inside of the fixing block 2. The right-angle rod is connected through the fixing block. Combined with the rotation adjustment of the rotating head, it is convenient for combination snap-fit ​​positioning and also convenient for rotation separation for disassembly, with high adaptability.

[0029] A friction block 23 is fixedly connected to one end of the right-angle rod 21. The friction block 23 is tightly connected to the end face of the fixed block 2. A limiting groove 24 is provided on one side surface of the sheet metal body 12. The limiting groove 24 is located on one side of the end of the right-angle rod 21. A limiting head 25 is fixedly connected to one end of the right-angle rod 21. The limiting head 25 is elastically engaged inside the limiting groove 24. By connecting the friction block to the right-angle rod, damping and limiting can be achieved to prevent loosening. In addition, the locking and positioning of the limiting head provides precise stability and convenient adjustment. After the body 12 is positioned by inserting the positioning head 15, it can fit against the side of the chassis body 1. Then, the right-angle rod 21 can be rotated so that the right-angle head faces down, thereby locking the limiting head 25 into the limiting groove 24. This combination positioning can lock the upper end of the sheet metal body 12 into the limiting position, thus ensuring stability and facilitating positioning adjustment. Furthermore, during disassembly, it can be manually rotated so that the end of the right-angle rod 21 faces up, allowing it to be separated from the sheet metal body 12 for easy removal without interference, demonstrating high adaptability.
