Computers are composed of software and hardware. Computer hardware refers to the electronic components and mechanical parts of the computer, including chassis, bus, power supply, memory, motherboard, graphics card, CPU, hard disk, etc. The main function of the computer chassis is to place and fix various computer accessories, and play a supporting and protective role; the computer chassis includes a case and side panels. The side panels are generally located on the left side of the case. The computer accessories can be installed in the case by opening the side panels.

[0003] During use, computer accessories may be damaged. For example, insufficient heat dissipation may cause damage to the motherboard, accessories may become loose, or dust may fall on the computer motherboard, hard disk, memory stick and other related hardware. After a long period of accumulation, it will lead to poor internal electrical contact and slow heat dissipation. This requires opening the side panel to inspect, repair or replace the hardware inside the chassis.

[0004] The existing box body and side panels are mainly fixed by screws. After the screws are turned for many times, the slotted groove or cross groove on the screw cap of the screw is easily damaged by the screwdriver, commonly known as "slipping the thread". After the screw is slipped, it is very inconvenient to remove the screw. Generally, destructive disassembly can only be performed, such as removing it with electric welding or a cutting gun, or slowly prying or clamping the screw cap with needle-nosed pliers and screwing it out, which can easily cause the threaded holes on the side panel or box body to deform, affecting the next use, and also increasing the time required for repairing the chassis, indirectly increasing the repair cost; and in the long-term use process, the threads on the screws are also prone to wear, resulting in poor fixing effect of the side panel.

[0025] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

[0026] The computer hardware fixing device described in this embodiment is as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the chassis body includes a box body 1 with an opening on the left and a side panel 2. The box body 1 is a rectangular structure. The box body 1 and the side panel 2 are the chassis structure of an existing computer. The box body 1 includes a top surface, a bottom surface, a front panel, a rear panel, and a right panel. The front panel of the box body 1 is the panel we often touch. The front panel has a USB interface and a power button, etc., and the side panel 2 is the left panel of the box body 1. Other hardware of the computer is installed in the box body 1 through the side panel 2.

[0027] The inner wall on the left side of the box body 1 is fixed with a fixing block 3, and the edge of the side plate 2 is provided with a plurality of through holes communicating with each other on the left and right sides. Figure 4 As shown, the edge of the side panel 2 is around the left side wall of the side panel 2, and the number of through holes on the side panel 2 is preferably 12, with 3 holes each opened at the top and bottom and the left and right sides of the side panel 2. Of course, in actual use, the appropriate number of through holes can be selected according to the height and width of the box body 1, and fixing rods 4 are independently installed in the through holes. The side wall of the fixing rod 4 close to one end of the fixing block 3 is fixed with a limiting block 7, and the outer side wall of the left end of the fixing rod 4 is fixed with a limiting block 7.

[0028] The fixing block 3 is provided with a first slot 3.1 for horizontal insertion of the limit block 7 and the fixing rod 4. Figure 5 and Figure 6 As shown, the first groove 3.1 includes a circular groove and a rectangular groove, the rectangular groove is used for inserting the limit block 7, and the circular groove is used for inserting the fixing rod 4. The bottom of the first groove 3.1 is provided with a second groove 3.2 for rotating the limit block 7, and the second groove 3.2 is a circular groove. The radius of the second groove 3.2 is a circular groove with the center of the circular groove of the first groove 3.1 as the center, and the distance from the center of the circular groove of the first groove 3.1 to the top of the rectangular groove as the radius, that is, the radius of the second groove 3.2 is a groove with the distance from the center of the end of the fixing rod 4 to the end of the limit block 7 away from the fixing rod 4 as the radius. Preferably, the rectangular groove of the first groove 3.1 is located above the circular groove, so that after the limit block 7 is inserted into the second groove 3.2, the limit block 7 can be rotated downward, so that the circular groove of the first groove 3.1 blocks the limit block 7, which can prevent the limit block 7 from escaping from the second groove 3.2 under non-human conditions.

[0029] A bearing is arranged between the fixing rod 4 and the through hole, the inner ring of the bearing is fixedly sleeved on the fixing rod 4, and the outer ring of the bearing is fixed to the through hole, so that the fixing rod 4 can rotate in the through hole through the bearing, and the fixing rod 4 can be prevented from moving horizontally in the through hole. When the side plate 2 is to be installed on the box body 1, the limit block 7 can be rotated to the top of the fixing rod 4 first, and then the side plate 2 is moved to insert the limit block 7 and the fixing rod 4 into the first groove 3.1, and then the limit block 7 is rotated by the fixing rod 4. This paragraph of text as a whole constitutes a limit assembly that prevents the fixing rod 4 from escaping from the through hole when the limit block 7 is located in the second groove 3.2.

[0030] The end face of the fixing rod 4 away from the fixing block 3 is flush with the side face of the side plate 2, the left end of the fixing rod 4 is flush with the left side wall of the side plate 2, the end of the fixing rod 4 away from the fixing block 3 is provided with a first groove with a prism structure, the left end of the fixing rod 4 is provided with a first groove, and a prism 5 with the same shape is arranged in the first groove, such as Figure 3 As shown, the prism 5 is in the shape of a hexagonal prism, and the first groove is in the shape of a hexagonal prism. The depth of the first groove is less than the length of the prism 5, so that the prism 5 exceeds the first groove. Of course, the prism 5 and the first groove can also be in the shape of a triangular prism. When in use, the left end of the fixing rod 4 is flush with the left side wall of the side panel 2, which can prevent the fixing rod 4 from exceeding the left side wall of the side panel 2, and avoid the fixing rod 4 protruding from the side panel 2 to cause obstruction, and it is also relatively neat and beautiful. By inserting the prism 5 into the first groove, it is convenient to rotate the fixing rod 4. After rotation, the prism 5 can be taken out of the first groove, so that the prism 5 becomes the key for rotating the fixing rod 4, thereby preventing some unrelated personnel from misoperating the fixing rod 4.

[0031] A hanging ring 6 is provided at one end of the prism 5. The hanging ring 6 is in a circular ring shape. The prism 5 can be hung on a keychain through the hanging ring 6, which is convenient for carrying the prism 5. Of course, the hanging ring 6 can also be an existing keychain structure.

[0032] The number of the fixing blocks 3 is consistent with the number of the through holes on the side plate 2, and they correspond one to one. The number of the through holes on the side plate 2 is 12. Figure 5 As shown, the number of the fixing blocks 3 is also 12. When the side panel 2 is located on the left side of the box body 1, the fixing blocks 3 are aligned with the through holes on the side panel 2. This can reduce the material usage of the fixing blocks 3 and save costs. Of course, in actual use, four fixing blocks 3 can also be provided, and the four fixing blocks 3 form a rectangular frame as a whole.

[0033] The left side surface of side panel 2 is flush with the left side wall of box body 1, and the width of side panel 2 is consistent with the width of the inner wall of box body 1, that is, the distance between the front and rear side walls of side panel 2 is consistent with the distance between the front and rear inner walls of box body 1, the height of side panel 2 is consistent with the height of the inner wall of box body 1, and the distance from the left side wall of fixing block 3 to the left side wall of box body 1 is equal to the thickness of side panel 2. When side panel 2 is fitted with fixing block 3, side panel 2 is located inside the left side wall of box body 1, and the left side wall of side panel 2 is flush with the left side wall of box body 1; of course, in actual use, the left side wall of fixing block 3 can also be flush with the left side wall of box body 1, the length of the front and rear side walls of side panel 2 is consistent with the length of the front and rear outer walls of box body 1, and the height of side panel 2 is consistent with the height of the outer wall of box body 1, so that the top and bottom ends of side panel 2 are flush with the top and bottom surfaces of box body 1, and the front and rear side walls of side panel 2 are flush with the front and rear side walls of box body 1.

[0034] like Figure 7 and Figure 8 As shown, the left end of the fixing rod 4 is fixed with a limiting plate 8, which is a circular plate. The diameter of the fixing rod 4 is smaller than that of the limiting plate 8. When the limiting block 7 is located in the second groove 3.2, the limiting plate 8 fits with the side plate 2. The length of the fixing rod 4 is equal to the depth of the first groove 3.1 plus the thickness of the side plate 2. In this way, when the limiting block 7 is inserted into the bottom of the first groove 3.1, the limiting plate 8 is flush with the left side wall of the side plate 2. Then, the fixing rod 4 is rotated by the limiting plate 8, so that the limiting block 7 is in the second groove 3.2, and the side plate 2 and the fixing block 3 are in close contact. This paragraph of text as a whole constitutes another structure of the limiting assembly that prevents the fixing rod 4 from escaping from the through hole when the limiting block 7 is located in the second groove 3.2.

[0035] The side plate 2 is provided with a third groove for inserting the limit plate 8, the thickness of the limit plate 8 is consistent with the depth of the third groove, and when the limit block 7 is located in the second groove 3.2, the limit plate 8 is fitted with the bottom of the third groove, and the length of the fixing rod 4 is equal to the depth of the first groove 3.1 plus the distance from the bottom of the third groove to the right side wall of the side plate 2. Similarly, when the limit block 7 is located at the bottom of the first groove 3.1, the limit plate 8 is fitted with the bottom of the third groove, and the limit plate 8 is located in the third groove, which can prevent the limit plate 8 from protruding out of the side plate 2. A second groove with a prismatic structure is provided at one end of the limit plate 8 away from the fixing rod 4, and a second prism with the same shape as the second groove is provided in the second groove. The shape of the second prism and the second groove is consistent with the shape of the first groove and the prism 5. The second prism also facilitates the rotation of the limit plate 8, thereby rotating the fixing rod 4.

[0036] Working principle:

[0037] When in use, to fix the side panel 2 on the box body 1, the limit block 7 is located at the top of the fixing rod 4, and then the fixing rod 4 and the limit block 7 are inserted from the first groove 3.1, so that the fixing rod 4 and the limit block 7 are located at the bottom of the first groove 3.1, and then the limit block 7 is rotated by the fixing rod 4 to make the limit block 7 located at the bottom of the fixing rod 4, so that the first groove 3.1 will block the limit block 7 and prevent the limit block 7 from escaping from the second groove 3.2. At the same time, the bearing or limit plate 8 in the first through hole will limit the movement of the fixing rod 4 and prevent the fixing rod 4 from escaping from the through hole, so that the side panel 2 and the fixing block 3 are fitted together to fix the side panel 2 to the box body 1; and when the side panel 2 is to be disassembled, Similarly, it is only necessary to rotate the limit block 7 through the fixing rod 4 so that the limit block 7 is located at the top of the fixing rod 4, and then pull the limit block 7 to the left through the fixing rod 4 to make the fixing rod 4 and the limit block 7 disengage from the first groove 3.1, so as to complete the separation of the side panel 2 and the fixing block 3, that is, to remove the side panel 2 from the left side of the box body 1, and fix the side panel 2 on the box body 1 by sliding and rotating the limit block 7 through the fixing rod 4. The operation is simple and can effectively reduce the slippage of the screws, making the installation and removal of the side panel 2 relatively simple, and it is not easy to be damaged compared with the screw fixing method. In this way, during use, it is convenient to open the side panel 2 to inspect, repair or replace the hardware in the box body 1.
