Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "plurality" means two or more.

[0041] Reference Figure 1-Figure 9 , which is an embodiment of the positioning column and clothing processing equipment of the utility model.

[0042] The clothes processing device may be a washing machine, a shoe washing machine, a clothes drying machine, etc. The clothes processing device comprises a housing, and the housing comprises a side plate 100 , a back plate, a bottom plate, a top plate, and a front plate 200 .

[0043] During assembly, the front plate 200 can be first positioned and locked on the side plate 100 by means of the positioning columns 300 , and then the front plate 200 can be fastened and connected by means of fasteners such as screws 500 .

[0044] Specifically, the side panel 100 and the front panel 200 respectively form a side panel fold 110 and a front panel fold 210 that are attached to each other. Figure 3 The front side edge of the side panel 100 is vertically bent inward to form a side panel fold 110. Figure 8 The two side edges of the front plate 200 are vertically bent backwards and then vertically bent inwards to form a front plate folded edge 210.

[0045] like Figure 5 As shown, a side panel fixing hole 111 and a side panel positioning hole 112 are provided on the side panel fold 110. Figure 8 As shown, a front plate positioning hole 211 is provided on the front plate folding edge 210 .

[0046] For the specific structure of the positioning column 300, see Figure 6 and Figure 7 The positioning column 300 includes a columnar body 310 , a positioning protrusion 320 and at least two undercut portions 330 .

[0047] The columnar body 310 is provided with a through hole 311 in the axial direction, the through hole 311 is a stepped hole, and one end surface of the columnar body 310 is a positioning surface A. The positioning surface A is used to position and abut against the side panel folding edge 110, and the through hole 311 is opposite to the side panel fixing hole 111, and is used to pass fasteners such as screws to fasten with the side panel folding edge 110.

[0048] The positioning protrusion 320 is disposed on the positioning surface of the columnar body 310 and is used to cooperate with the side plate positioning hole 112 on the side plate 100 to achieve precise positioning.

[0049] The undercut portion 330 is disposed on the side of the columnar body 310 , and has an undercut locking surface B at one end close to the positioning surface, which is used to cooperate with a corresponding structure on the front plate 200 to achieve locking and fixing of the front plate 200 .

[0050] like Figure 8 and Fig. 9 As shown, when the positioning column 300 is assembled, the positioning column 300 is inserted into the side panel positioning hole 112 through the positioning protrusion 320, so that the positioning surface of the positioning column 300 abuts against the front side of the side panel folding edge 110; the screw 500 passes through the through hole 311 of the positioning column 300 and the side panel fixing hole 111 to fix the positioning column 300 on the side panel folding edge 110.

[0051] When assembling the front plate 200, align the front plate positioning hole 211 on the front plate fold 210 with the positioning post 300 and push it vertically in a direction perpendicular to the front plate 200 (such as Figure 2 Due to the structural obstruction in the dotted frame shown, the front plate 200 can only be assembled vertically). The positioning column 300 is fixed to the front plate folded edge 210 through the undercut portion 330, thereby achieving rapid assembly and firm locking of the front plate 200.

[0052] The above-mentioned positioning column 300 can enable the front panel 200 to be vertically installed into the positioning column 300, and the assembly method is simple and quick, thereby improving the assembly efficiency; at the same time, through the locking effect of the undercut portion 330, it can ensure a tight fit between the front panel 200 and the positioning column 300 and the side panel 100, and there will be no flashing seam phenomenon, thereby improving the overall quality and appearance of the product.

[0053] Furthermore, the columnar body 310 can adopt a cylindrical structure for easy processing and assembly. The outer surface of one end of the columnar body 310 away from the positioning protrusion 320 is inclined inward to form a tapered side surface C, which helps to guide the front plate 200 to smoothly enter the positioning column 300 during the assembly process, thereby improving assembly efficiency.

[0054] The positioning protrusion 320 can be designed as a cylindrical structure, and at least two can be provided as needed to enhance the stability and accuracy of positioning. In other embodiments, one positioning protrusion can be provided, and its cross section can be asymmetric or irregular, and the side plate positioning hole is provided with a matching shape corresponding thereto.

[0055] The side wall of the columnar body 310 may be provided with an undercut groove, and the undercut portion 330 is provided in the undercut groove. One end of the undercut portion 330 is connected to the undercut groove, and the other end forms an inclined undercut locking surface B. Such a design enables the front plate 200 to slide in smoothly and be firmly locked during assembly.

[0056] A plurality of positioning posts 300 may be respectively disposed on the side panels 100 on the left and right sides to improve positioning accuracy and structural strength.

[0057] Furthermore, the periphery of the front panel positioning hole 211 may form a front panel flange portion 212 that is folded away from the side panel flange 110, such as Fig. 9 As shown, the edge of the front plate flange 212 is fixedly abutted against the undercut locking surface B of the undercut portion 330. The front plate flange 212 can not only enhance the structural strength at the front plate positioning hole 211, but also, in this embodiment, the undercut portion 330 is a certain distance away from the positioning surface, and the height of the front plate flange 212 can make up for the distance between the undercut locking surface and the positioning surface, so that the front plate folding edge 210 and the side plate folding edge 110 can fit tightly. It can be understood that in other embodiments, when the front plate positioning hole 211 has no flange structure, in order to ensure that the front plate folding edge 210 and the side plate folding edge 110 can fit tightly, the undercut locking surface of the undercut portion 330 needs to be set close to the positioning surface.

[0058] In this embodiment, if Figure 5 As shown, an inwardly recessed pressing profile 113 may be provided at the position of the side panel fold 110 abutting against the positioning surface of the positioning post 300 , so as to further improve the positioning accuracy and stability when the positioning post 300 is assembled.

[0059] In order to further enhance the strength and stability of the structure, a reinforcing plate 400 may be provided inside the side panel fold 110. The reinforcing plate 400 is fixedly connected to the side panel 100, and a reinforcing plate mounting hole 410 is provided at a position corresponding to the side panel fixing hole 111 so that screws can pass through for fastening.

[0060] The periphery of the reinforcing plate mounting hole 410 may form a reinforcing plate flange portion that is folded away from the side plate flange 110. The fastener passes through the through hole 311, the side plate fixing hole 111 and the reinforcing plate mounting hole 410 to fix the positioning column 300 to the side plate flange 110 and the reinforcing plate 400, thereby forming a stable overall structure.

[0061] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the above embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the above embodiments, or to replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions claimed to be protected by the present invention.
