Description

Technical Field

[0001] The utility model relates to the technical field of chassis sheet metal installation structures, in particular to a fixing mechanism for chassis sheet metal parts. Background Art

[0002] The chassis is a box used to install some electronic components. It is also the installation carrier of many integrated circuits. The most common one is the computer host chassis. In order to facilitate the disassembly and replacement of internal components and daily maintenance, one side panel of the chassis needs to be removable, which is also a common feature of many different chassis nowadays.

[0003] The side panels of a computer chassis are generally made of metal, and there are also side panels of many different materials. Regardless of the material, they are not convenient to install. Traditional computer chassis side panels are fixed by multiple screws, and require a specific screwdriver to disassemble them. This is undoubtedly inconvenient, especially when there is no screwdriver. For this purpose, a fixing mechanism for the sheet metal parts of the chassis is proposed. Utility Model Content

[0004] The technical solution adopted by the present invention to solve the technical problem is: a fixing mechanism for the sheet metal parts of a chassis, comprising a box body, a side panel is provided on one side of the box body, and a connecting plate is embedded and connected at the four corners of the side panel, and a pair of plugs are provided on the side wall opposite to the connecting plate and the box body, and the plugs are two semi-cylindrical structures, and the edge of one end of the plug close to the connecting plate is fixedly connected to an extension plate, and the end of the extension plate away from the plug is fixedly connected to a torsion spring, and the torsion spring is fixedly connected to the side wall of the connecting plate through its side away from the extension plate, the interior of the plug away from the connecting plate is a hollow structure and is fixedly connected to a clamping plate near the inner edge, the clamping plate is a semi-annular structure, and the outer edge of the clamping plate is an inclined structure.

[0005] As an optimal technical solution of the present invention, a control panel is provided on the side wall inside the column and close to the hollow position. The bottom end of the control panel is rotatably connected to the side wall of the column through a torsion spring. The adjacent ends of the two columns are rotatably connected with a rotating shaft, and the two control panels are inclined structures.

[0006] As an optimal technical solution of the present invention, one side of the rotating shaft is rotatably connected to a connecting column, and the end of the connecting column away from the rotating shaft is fixedly connected to a control rod. The control rod is telescopically connected in the middle of the connecting plate, and two extension plates are located on both sides of the control rod.

[0007] As an optimal technical solution of the present invention, slots are provided on the side walls of the box body opposite to the side panels and near the four corners, a fixed column is fixedly connected to one side of the slot, and a circle of card slots is provided on the outer wall of the fixed column, and the position of the slot is opposite to the plug column.

[0008] As a preferred technical solution of the present invention, the plug is inserted into the slot, the plug is clamped in the slot via a clamping plate, and a sealing strip is fixedly connected to the edge of the side plate and the side wall opposite to the slot.

[0009] The present invention has the following advantages: during installation, it is only necessary to align the plug post with the slot, and then push the side panel to insert the plug post into the slot. As the force is applied, the plug post will rotate and expand along the torsion spring. When the card plate is aligned with the slot, the card plate will be smoothly connected to the slot under the action of the torsion spring, thereby realizing the connection and positioning of the side panel. For disassembly, it is only necessary to press the control lever to squeeze the rotating shaft through the connecting column, so as to adjust the originally tilted control panel into an upright state, thereby pushing the plug post up and pulling the card plate out of the slot, and then pulling the side panel outward to pull the plug post out of the slot to realize disassembly. The above effects can effectively improve the efficiency of disassembly and assembly of the side panel without the need for any tools, thereby improving the convenience of disassembly and assembly.

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] Please refer to Figure 1-3The utility model is a fixing mechanism for a chassis sheet metal part, comprising a box body 1, a side panel 3 is provided on one side of the box body 1, and a connecting plate 4 is connected and inlaid at the four corners of the side panel 3. A pair of plug posts 5 are provided on the side wall opposite to the connecting plate 4 and the box body 1. The plug posts 5 are two semi-cylindrical structures. An end edge of the plug post 5 close to the connecting plate 4 is fixedly connected to an extension plate 7. An end of the extension plate 7 away from the plug post 5 is fixedly connected to a torsion spring 8. The torsion spring 8 is fixedly connected to the side wall of the connecting plate 4 through its side away from the extension plate 7. The plug post 5 is away from the connecting plate 4. The interior is a hollow structure and is fixedly connected to a card plate 10 near the inner edge. The card plate 10 is a semi-annular structure, and the outer edge of the card plate 10 is an inclined structure. Slots 2 are provided on the side walls of the box body 1 opposite to the side panels 3 and near the four corners. A fixing column 11 is fixedly connected to one side of the slot 2, and a circle of card slots 12 is provided on the outer wall of the fixing column 11. The position of the slot 2 is opposite to the plug column 5, and the plug column 5 is inserted into the slot 2. The plug column 5 is clamped in the card slot 12 through the card plate 10, and a sealing strip is fixedly connected to the edge of the side wall opposite to the side panel 3 and the slot 2.

[0016] The technical effect of this solution is as follows: insert the plug 5 into the corresponding slot 2, and as the plug 5 is inserted, it will expand, and then the card plate 10 is connected to the corresponding card slot 12 under the drive of the torsion spring 8, so as to realize the connection and positioning of the box body 1 and the side panel 3. When disassembly is required, it is only necessary to press the operating lever 6 inward. As the operating lever 6 is compressed, the transmission of the connecting column 14 pushes the rotating shaft 13 to move. As the rotating shaft 13 is pushed, the two control panels 9 will be driven from an inclined state to an upright state, so that the two plugs 5 can be pushed outward, thereby moving the card plate 10 out of the card slot 12, and then pulling the side panel 3 outward can realize disassembly. The entire disassembly and assembly process is very convenient and does not require specific tools, which improves the convenience of disassembly and assembly.

[0017] A control panel 9 is provided inside the column 5 and on the side wall near the hollow position. The bottom end of the control panel 9 is rotatably connected to the side wall of the column 5 through a torsion spring 8. The adjacent ends of the two columns 5 are rotatably connected to a rotating shaft 13. The two control panels 9 are inclined structures. One side of the rotating shaft 13 is rotatably connected to a connecting column 14. The end of the connecting column 14 away from the rotating shaft 13 is fixedly connected to a control rod 6. The control rod 6 is telescopically connected and inserted in the middle of the connecting plate 4, and the two extension plates 7 are located on both sides of the control rod 6.

[0018] The technical effect of this solution is: because the control board 9 is connected to the plug post 5 through the torsion spring 8, it is always in an inclined state under the influence of the torsion spring 8 under normal circumstances, ensuring the stable closure of the plug post 5. At the same time, the plug post 5 is also connected to the connecting plate 4 through the torsion spring 8, so under the drive of the two torsion springs 8, it can be ensured that the plug post 5 is always in a closed state without sufficient force, ensuring the reliability of the connection between the box body 1 and the side panel 3.

[0019] When the lever 10 is in alignment with the slot 12, the two latches 5 are closed by the torsion spring 8, and the lever 10 is then pulled out of the slot 12, thereby releasing the latch 5 from the engagement.

[0020] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.

[0021] Other parts of the present invention that are not described in detail belong to the prior art and will not be described in detail here.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
