Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal parts, in particular to a combined sheet metal part. Background Art

[0002] Sheet metal is a comprehensive cold processing technology for metal sheets, including shearing, punching, cutting, compounding, folding, welding, riveting, splicing and forming, etc. Its notable feature is that the thickness of the same part is consistent. The products processed by the sheet metal process are called sheet metal parts. Sheet metal parts are made by filament power winding, laser cutting, heavy processing, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, metal plate bending forming, die forging and water jet cutting. Existing capacitor cabinets and electric boxes basically use sheet metal parts in production and processing. Capacitor cabinets and electric boxes need to be assembled and installed with sheet metal parts. Existing sheet metal parts are usually fixed with bolts when assembled and installed. It takes a lot of time to align the threaded holes between the sheet metal parts during installation, which makes the installation of sheet metal parts more complicated, inconvenient to disassemble and install the sheet metal parts conveniently, and makes the efficiency of sheet metal parts relatively low when assembled and installed;

[0003] After searching, in the prior art, Chinese patent application number: CN201922206746.9 discloses a modular sheet metal part that can be quickly disassembled and assembled. The utility model realizes close cooperation between the first modular block and the second modular block through the mutual clamping and interlocking of the connecting block of the first modular block and the connecting groove of the second modular block, and the assembly effect is good. At the same time, the mutual cooperation and embedding of the positioning guide block in the middle of the first modular block and the positioning groove of the second modular block realizes the rapid alignment of the first modular block and the second modular block, which is convenient for rapid assembly. The first modular block and the second modular block are fixedly connected by a positioning rod with a square cross section, which is in place in one step and easy to disassemble and assemble. At the same time, the first modular block and the second modular block can be aligned in plane and the vertical connection mode can be freely switched, which has strong flexibility.

[0004] However, the device has a problem that when splicing, the operator needs to fit the sheet metal parts together and then fix them with bolts. However, when fixing, the sheet metal parts are often not fitted tightly enough, resulting in the inability to align the threaded holes, making the operation difficult. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] Reference Figure 1-Figure 5A combined sheet metal part includes a sheet metal frame 1, a sheet metal cover 3 and a sheet metal base 9. The top inner wall of the sheet metal frame 1 is fixedly connected with a positioning frame 2. Two fixing grooves are provided on the two side walls of the sheet metal cover 3. The top of the inner wall of the fixing groove is rotatably connected with a damping shaft 4. The damping shaft 4 is connected with a mounting slide 7 through a linkage component. Further, the linkage component includes a linkage gear 5 fixedly connected to the bottom of the damping shaft 4. The linkage gear 5 is meshingly connected with a linkage rack 6. The end of the linkage rack 6 is fixedly connected to the side wall of the mounting slide 7. By setting the linkage component, when installing the sheet metal frame 1 and the sheet metal cover 3, first place the sheet metal cover 3 on The positioning frame 2 can ensure the accurate positioning of the sheet metal cover 3, and then the damping shaft 4 is rotated to drive the linkage gear 5 to rotate. At this time, since the linkage rack 6 is meshed with the linkage gear 5 and the mounting slide 7 and the linkage gear 5 are both slidably connected with the inner wall of the fixing groove, as the linkage gear 5 rotates, the linkage rack 6 can drive the mounting slide 7 to rotate. At this time, the mounting slide 7 can drive the mounting pin 8 to be inserted into the mounting hole, thereby realizing the installation between the sheet metal frame 1 and the sheet metal cover 3. The mounting pin 8 can directly fix the sheet metal cover on the top of the sheet metal frame, thereby avoiding the problem of inaccurate positioning during bolt connection.

[0022] A mounting pin 8 is fixedly connected to the side wall of the mounting slide plate 7. Furthermore, the mounting slide plate 7 is located in the fixing groove and is slidably connected to the inner wall thereof. The linkage rack 6 is located in the fixing groove and is slidably connected to the inner wall thereof. A mounting hole adapted to the mounting pin 8 is provided on the inner wall of the sheet metal frame 1 located at the top of the positioning frame 2.

A fixing screw hole is provided on the inner wall of the limit groove above the trapezoidal plug plate 13, and a fixing bolt 14 is threadedly connected to the inner wall of the fixing screw hole. When installing the sheet metal frame 1 and the sheet metal base 9, first insert the limit frame 10 at the bottom of the sheet metal frame 1 into the limit groove at the top of the sheet metal base 9. As the limit frame 10 is inserted into the limit groove at the top of the sheet metal base 9, When the slot reaches the position of the trapezoidal plug plate 13, the limiting slide plate 12 drives the trapezoidal plug plate 13 to slide outward under the action of the limiting spring 11, and the trapezoidal plug plate 13 is inserted into the slot. The trapezoidal plug plate 13 can directly fix the limiting frame 10, and the mounting screw holes on the limiting frame 10 will be aligned with the fixing screw holes. In order to enhance the stability of the connection, the limiting frame 10 can be directly fixed with bolts. At this time, the problem that the mounting screw holes and the fixing screw holes cannot be aligned can be effectively avoided, and the trapezoidal plug plate can effectively ensure the stability of the limiting frame when the fixing bolts 14 are installed.
