[0033] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features within these embodiments may be combined with one another, unless they conflict.

[0034] The purpose of the utility model is to provide a sheet metal shell with a quick assembly structure in view of the defects of the prior art.

[0035] Example 1

[0036] This embodiment provides a sheet metal housing with a quick assembly structure, such as Figure 1-5 As shown, it includes a bottom shell 1 and an upper cover 2 adapted to the bottom shell 1 . The upper cover 2 and the bottom shell 1 are detachably connected through adapted buckle structures and slot structures.

[0037] The sheet metal housing of this embodiment is cut from sheet metal using a CNC cutting machine or other process according to the design drawings to form the initial shapes of the upper cover 2 and bottom shell 1. The edges and sidewalls of the upper cover 2 and bottom shell 1 are then formed through bending and other processes. The initial shapes of the slot structure and buckle structure are also formed by bending. The sheet metal thickness is selected to be 0.8mm to 1.5mm to ensure the elasticity and strength of the elastic buckle.

[0038] The buckle structure includes a first buckle and a second buckle; the slot structure includes a first fixed slot 5 and a second fixed slot 6; the first buckle cooperates with the first fixed slot 5, and the second buckle cooperates with the second fixed slot 6.

[0039] The first buckle adopts a fixed buckle 3, and the second buckle adopts a fixed buckle or an elastic buckle 4, that is, the fixed buckle 3 cooperates with the first fixed slot 5, and the fixed buckle or elastic buckle 4 cooperates with the second fixed slot 6. This embodiment takes the elastic buckle 4 as an example for explanation.

[0040] The fixing clip 3 and the elastic clip 4 are respectively installed on both sides of the upper cover 2, and the first fixing slot 5 and the second fixing slot 6 are respectively installed on both sides of the bottom shell 1, and the fixing clip 3 and the first fixing slot 5 are adapted and are both located on one side of the sheet metal shell, and the elastic clip 4 and the second fixing slot 6 are adapted and are both located on the other side of the sheet metal shell, so that the fixing clip 3 is clamped with the first fixing slot 5, and the elastic clip 4 is clamped with the second fixing slot 6; in this embodiment, the height positions of the first fixing slot 5 and the second fixing slot 6 formed on both sides of the bottom shell are different, and the height positions of the fixing clips 3 and the elastic clip 4 formed on both sides of the upper cover are also different. For example, in this embodiment, the elastic clip 4 is set close to the top of the upper cover 2, the fixing clip 3 is set close to the bottom of the upper cover 2, the second fixing slot 6 is set close to the top of the bottom shell 1, and the first fixing slot 5 is set away from the top of the bottom shell 1. By setting different heights, a foolproof effect is achieved to prevent the upper cover 2 and the bottom shell 1 from being misplaced and installed by rotating 180 degrees in the horizontal plane, which causes the indicator light port on the upper cover 2 and the fan position to be misplaced.

[0041] In the process of manufacturing the upper cover 2 and the bottom shell 1 of this embodiment, the elastic buckle 4, the fixed buckle 3, the first fixed slot 5, and the second fixed slot 6 are formed simultaneously by bending the upper cover and the bottom shell after the plate is cut. No additional processing steps are added. Compared with the screw assembly structure, the pressing rivet nut or the hole tapping process is omitted, thereby improving the processing efficiency.

[0042] In this embodiment, in order to ensure that the excess material falls off smoothly and automatically when the plate is cut, the width of the elastic clip cutting groove 41 is preferably 1.5mm~2.0mm, so that the elastic clip 4 forms a square structure with a width of 1.0mm~2.0mm and a length of 10.0mm~20.0mm, thereby ensuring the elasticity and strength of the elastic clip 4. The width of the elastic clip cutting groove 41 provides deformation space for the elastic clip 4.

[0043] A snap-on installation guide structure 7 is provided on both sides of the bottom shell 1 to ensure that the elastic snap-on can be smoothly pressed into the fixed slot. The specific snap-on installation guide structure 7 is arranged at both ends of each side of the bottom shell 1 and close to the top. Both ends of each side of the upper cover 2 are notches that are compatible with the snap-on installation guide structure 7. When the upper cover 2 is installed with the bottom shell 1, the upper cover 2 moves downward along the snap-on installation guide structure 7 through the notch, thereby causing the elastic snap-on 4 to be engaged with the second fixed slot 6, and the fixed snap-on 3 to be engaged with the first fixed slot 5.

[0044] A disassembly handle structure 8 is provided near the middle of both sides of the upper cover. The disassembly handle structure 8 may be a groove structure so that the upper cover can be easily disassembled when necessary.

[0045] In this embodiment, a fan air inlet and a fan pressure riveted stud are further provided in the middle position of the top of the upper cover 2, an indicator light port is provided near the other side of the top of the upper cover 2, PCB board mounting studs and PCB board mounting pressure riveted studs are further provided in the bottom shell 1, and ventilation and heat dissipation holes are also opened on the outer shell of the bottom shell 1; it should be noted that the actual conditions of the other components installed on the bottom shell 1 and the upper cover 2 are set, and this embodiment has only been described in detail.

[0046] The specific usage of the sheet metal housing in this embodiment is as follows:

[0047] Assembly method of sheet metal housing:

[0048] Place the upper cover 2 on the bottom shell 1 and ensure that the position is aligned; then press the side of the elastic clip 4, and use the clip installation guide structure 7 on the bottom shell 1 and the elasticity of the elastic clip 4 to press the elastic clip 4 into the second fixed slot 6; then, press the fixed slot 3 on the other side into the matching first fixed slot 5 to complete the assembly of the upper cover 2 and the bottom shell 1.

[0049] How to disassemble the sheet metal casing:

[0050] After the upper cover 2 and the shell 1 are assembled, the upper cover can be removed by manually fastening the disassembly buckle structure 8 on both sides of the upper cover. If necessary, a tool (such as a flat-blade screwdriver) can be used to first remove the elastic buckle 4 from the second fixed slot 6, and then the upper cover 2 can be removed by manually fastening the disassembly buckle structure 8 on both sides of the upper cover.

[0052] 1. Quick assembly and disassembly: The sheet metal housing of the utility model realizes the function of quick assembly and disassembly by designing fixed buckles and elastic buckle structures, which significantly improves production efficiency and reduces labor costs.
