[0040] Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0041] like Figure 1-10 As shown, the utility model provides a connecting device for detachably connecting two sheet metal parts of a cabinet, wherein the connecting device comprises a first connecting component 100 and a second connecting component, and the first connecting component 100 and the second connecting component are respectively fixedly mounted on the two sheet metal parts to be connected.

[0042] Furthermore, the structures of the first connection component 100 and the second connection component are completely the same, and both include a substrate 1 and a clamping member 2. The substrate 1 is provided with a first circular through hole 111 and a first strip hole 112. The first circular through hole 111 is connected to the first strip hole 112, and the inner diameter of the first circular through hole 111 is greater than the width of the first strip hole 112. The first circular through hole 111 and the first strip hole 112 form a structure similar to a gourd hole with one side larger and the other side smaller. The clamping member 2 includes a connecting column 22 and a fixing head 21. The first end of the connecting column 22 is vertically connected to the substrate 1, and the second end of the connecting column 22 is connected to the fixing head 21. The diameter of the fixing head 21 is greater than the diameter of the connecting column 22, the diameter of the fixing head 21 is smaller than the inner diameter of the first circular through hole 111 and larger than the width of the first strip hole 112, and the diameter of the connecting column 22 is smaller than the width of the first strip hole 112. The first strip hole 112, the first circular through hole 111 and the connecting column 22 are located on the same straight line. When the first connecting component 100 is connected to the second connecting component, the connecting column 22 of the first connecting component 100 slides into the first strip hole 112 of the second connecting component after the fixing head 21 thereof passes through the first circular through hole 111 of the second connecting component, so that the connecting component 2 of the first connecting component 100 is clamped in the strip hole of the second connecting component; and, the connecting column 22 of the second connecting component slides into the first strip hole 112 of the first connecting component 100 after the fixing head 21 thereof passes through the first circular through hole 111 of the first connecting component 100, so that the connecting component 2 of the second connecting component is clamped in the strip hole of the first connecting component 100.

[0043] When assembling the first connecting component 100 and the second connecting component, the clamping piece 2 is directly engaged with the other party's bar hole. The installation method is simple, and the two clamping pieces 2 make the connection more stable and stronger. Moreover, the first connecting component 100 and the second connecting component combine the functions of traditional male buckles and female buckles, and there is no need to produce two types of connecting parts, male buckles and female buckles, which reduces the manufacturing difficulty and improves the production efficiency.

[0044] The substrate 1 is provided with a first boss 113, the cross section of which is fan-shaped, and the first boss 113 is provided on the side of the first strip hole 112 away from the first circular through hole 111. The first boss 113 is provided around the first strip hole 112, and after the clamping member 2 is clamped into the strip hole, the fixing head 21 abuts against the first boss 113 to compensate for the gap between the two sheet metal parts through the first boss 113, thereby increasing the stability of the connection between the two sheet metal parts. In a preferred embodiment, both ends of the first boss 113 are provided with inclined surfaces 114, so that the side of the first boss 113 close to the large hole end smoothly transitions with the surface of the substrate 1 through the inclined surface 114, so that the clamping member 2 can quickly slide into the strip hole, thereby improving the convenience of operation.

[0045] The base plate 1 is also provided with a fixing hole 12, and a connecting column 22 is connected to the fixing hole 12. In a specific embodiment, the connecting column 22 is fixedly connected to the fixing hole 12 by riveting; or an internal thread is provided in the fixing hole 12, and a fixing column 23 having a diameter smaller than that of the connecting column 22 is provided at the first end of the connecting column 22, and the fixed rod is threadedly connected to the fixing hole 12; or the fixing column 23 is sleeved in the fixing hole 12 and fixed by welding.

[0046] The central axes of the fixing hole 12, the first circular through hole 111 and the first strip hole 112 are located on the same plane, and the fixing hole 12 is close to the first end of the substrate 1. Preferably, the central axes of the fixing hole 12, the first circular through hole 111 and the first strip hole 112 are all located on the symmetric plane of the substrate 1. The first circular through hole 111 and the first strip hole 112 are close to the second end of the substrate 1. When the first connecting component 100 is connected to the second connecting component, as long as the first connecting component 100 is installed upside down on the sheet metal, the fixing head 21 of the first connecting component 100 can be directed toward the first circular through hole 111 of the second connecting component, and the fixing head 21 of the second connecting component can be directed toward the first circular through hole 111 of the first connecting component 100.

[0047] At least one second boss 13 is disposed on the substrate 1, and the second boss 13 and the clamping member 2 are located on the same surface of the substrate 1. In a preferred embodiment, the substrate 1 is directly stamped and formed to reduce the difficulty of processing.

[0048] In addition, the utility model also provides a cabinet, which includes multiple sheet metal parts and multiple connecting devices.

At this time, the first circular through hole 111 corresponds to the second circular through hole 2021, the first strip hole 112 corresponds to the second strip hole 2022, and the connecting column 22 is sleeved in the third strip hole 2012. When installing the second connection component, the fixing head 21 is passed through the second circular through hole 2021 and then slid down into the second strip hole 2022, and then the base plate 1 is fixed on the second sheet metal 300. At this time, the first circular through hole 111 corresponds to the third circular through hole 2011, the first strip hole 112 corresponds to the third strip hole 2012, and the connecting column 22 is sleeved in the second strip hole 2022. When assembling the cabinet, the first connection component 100 and the second connection component can be directly engaged with each other's strip holes.

[0050] A plurality of fourth circular through holes 203 are provided on the sheet metal component, and the second bosses 13 are fixedly connected to the fourth circular through holes 203 correspondingly. The second bosses 13 not only play a positioning role, but also facilitate welding and fixing the substrate 1 to the sheet metal component.

[0051] When leaving the factory, the first connecting component 100 and the second connecting component have been pre-fixed (welded) to the first sheet metal part 200 and the second sheet metal part 300, respectively. During assembly, the clamping member 2 on the first sheet metal part 200 is aligned and inserted into the third circular through hole 2011 on the second sheet metal part 300, and the clamping member 2 on the second sheet metal part 300 is aligned and inserted into the third circular through hole 2011 on the first sheet metal part 200, and then the first sheet metal part 200 is pushed to slide relative to the second sheet metal part 300, so that the clamping member 2 slides from the corresponding circular through hole into the strip hole and abuts against the first boss 113.
