[0001] The utility model relates to the technical field of electroplating tooling, in particular to an electroplating quick locking device for a metal shell of an electronic product. Background Art

[0002] The metal casing of electronic products usually needs to be electroplated to give the casing surface some special properties.

[0003] like Fig. 1-2 As shown, an electronic product housing to be processed in this embodiment includes a metal part and a plastic part, wherein the metal parts 1 and 2 are separated by a plastic part. Therefore, during the electroplating process of the above-mentioned product, it is necessary to apply positive and negative voltages to the two metal parts respectively to complete the electroplating. At the same time, the current production model on the market adopts the traditional manual installation of the metal housing on the electroplating hanger by bolting. This method is relatively traditional. Although it can complete the assembly of the metal housing, the traditional assembly method has the following main disadvantages: First, since the manual operation of fixing the metal housing to the locking device with several screws is relatively multi-step, it takes a relatively long time and is relatively slow; second, the screws used are immersed in the strong acid of the electroplating tank for a long time, and repeated disassembly and assembly can easily cause the threads to slip, and they need to be replaced after several uses, which has a high production cost. Utility Model Content

[0004] The purpose of this utility model is to provide a quick-read locking device for electroplating the metal shell of an electronic product to at least solve one of the above problems. The utility model adopts the following technical solutions:

DETAILED DESCRIPTION

[0027] In order to facilitate the understanding of those skilled in the art, the utility model is further described below in combination with examples and drawings, and the content mentioned in the implementation manner is not a limitation on the utility model. The utility model is described in detail below in combination with drawings.

[0028] As Fig. 1-2 shown, it is a metal shell of an electronic product needing electroplating, which is related to the utility model embodiment, which mainly comprises two metal pieces 1 and a plastic piece 2 for separating the two metal pieces 1, the electroplating quick locking device provided by the utility model embodiment can quickly lock the metal shell and install it on the electroplating hanger, at the same time, the two metal pieces 1 can be conducted at the same time, which is convenient for passing the two metal pieces 1 into positive and negative voltage for electroplating processing.

[0029] As Fig. 3-7The embodiment of the present invention provides a quick locking device for electroplating a metal shell of an electronic product, comprising: a base 100 and a connecting assembly 200. During the process of locking the metal shell, the metal shell is placed between the base 100 and the connecting assembly 200, and the shell is fixed by the clamping connection between the base 100 and the connecting assembly 200, so that the locking device is hung on the electroplating hanger. Specifically, a connecting column 111 is formed on one end surface of the base 100, and the connecting column 111 is provided with a clamping portion 112 extending radially; the connecting assembly 200 includes a bracket 210 and a connecting piece 220, wherein a clamping groove 211 is provided on the bracket 210 for the connecting column 111 to pass through and be clamped therein, the connecting piece 220 is fixedly mounted on the bracket 210, and a plurality of connecting legs 221 extend outward from the edge of the connecting piece 220, and the ends of the connecting legs 221 are bent toward the base 100 to form abutting ends 222.

[0030] When locking the metal shell, the metal shell is placed between the base 100 and the connecting assembly 200, and the connecting column 111 and the card slot 211 on the bracket 210 are engaged with each other, thereby locking the metal shell. Specifically, Fig. 4-6 As shown, the slot 211 has an avoidance hole for the clamping portion 112 to pass through, and a clamping block is also provided. When the connecting column 111 extends out of the slot 211 along the avoidance hole, the base 100 is rotated so that the clamping portion 112 is rotated to the bottom of the clamping block, thereby locking the connecting column 111 in the slot 211. At this time, the base 100 locks the metal shell inside the device. At this time, the abutting ends 222 of the several connecting feet 221 on the connecting piece 220 are respectively abutted against the two metal parts 1, thereby connecting the metal parts 1 in series through the connecting piece 220. Only one set of positive and negative poles can be set to complete the application of positive and negative voltages to the metal part 1, which is convenient for electroplating processing.

[0031] The locking device provided by the embodiment of the present invention can quickly lock the metal shell. The shell can be locked only by mutually engaging the base 100 and the connecting assembly 200. The locking method is simple and reliable, which can reduce the labor intensity of manual labor in the process of assembling the metal shell on the electroplating hanger and avoid the above-mentioned problems caused by the bolt locking process, thereby saving production costs and improving production efficiency. It is worth noting that after the metal shell is locked in the present device, the connecting pin 221 on the connecting piece 220 extends outward, which can make the abutting end 222 abut against the two metal parts 1. After the metal shell is locked, the abutting end 222 is pressed against the two metal pieces, thereby causing the connecting pin 221 to produce elastic deformation. The elastic force of the connecting pin 221 can make the abutting end 222 and the metal piece directly contact each other tightly and reliably, thereby ensuring conductivity during the electroplating process and ensuring the electroplating effect.

[0032] In the embodiment of the present invention, in order to be able to quickly assemble the base 100 and the connecting assembly 200, as shown in FIG. Fig. 3-6 As shown, a rotating portion 113 is provided on the end face of the base 100 facing away from the connecting assembly 200. The rotating portion 113 protrudes from the base 100 and includes two opposing and parallel torsional flat surfaces 114 on its side. In a further improvement, a notch 115 is formed on the end face of the rotating portion 113, recessed into the end face of the rotating portion 113. The notch 115 has a straight or cross-shaped structure. In other words, the two torsional flat surfaces 114 of the rotating portion 113 make it easier to clamp the rotating portion 113, thereby driving the base 100 to rotate and securely engage the base 100 with the connecting member. Similarly, the rotating portion 113 can also be operated through the slot.

[0033] In this embodiment, in order to ensure high precision in the connection between the base 100 and the connecting assembly 200, at least two positioning holes 101 are formed on the base 100, and positioning posts 201 that match the positioning holes 101 are provided on the bracket. In addition, to prevent errors between the positioning posts 201 and the positioning holes 101 during assembly, fool-proof designs are provided on the at least two positioning holes 101 and the at least two positioning posts 201. Fig. 3-6 As shown, in this embodiment, two positioning posts 201 and two positioning holes 101 are respectively provided. By setting the two positioning posts 201 to different diameters, fool-proofing is achieved. In other embodiments, they can also be set to different cross-sectional shapes to prevent fool-proofing.

[0034] In this embodiment, in order to ensure the accuracy of locking the base 100 and the connecting assembly 200 and facilitate separation and assembly, as shown in FIG. Fig. 5As shown, this embodiment designs the structure of the base 100, the connecting post 111, and the rotating portion 113. A through hole 102 is defined on the base 100, and a rod 110 is rotatably connected within the through hole 102. One end of the rod 110 is defined as the connecting post 111, and the other end is defined as the rotating portion 113. A retaining spring 116 is also provided on the rod to engage therewith and restrict axial movement of the rod. In other words, the connecting post 111 and the rotating portion 113 are configured as an integrated structure and are capable of rotating within the through hole 102, thereby rotating the engaging portion 112 to a position corresponding to or offset from the avoidance hole, thereby locking or unlocking the connecting post 111 within the retaining groove 211. The integrated rotating portion 113 and connecting post 111 enable the base 100 and the bracket 210 to be locked and released after positioning, thereby ensuring the precise assembly of the base 100 and the connecting assembly 200.

[0035] In this embodiment, in order to facilitate the assembly of the connecting column 111 and the rotating part 113 of the integrated structure on the base 100, the through hole 102 includes a main hole 1021, and a side hole 1022 adapted to the clamping part 112 is opened along the edge of the main hole 1021. During the assembly process, the clamping part 112 located on the connecting column 111 can pass through the side hole 1022, thereby improving the efficiency of assembly, and the clamping part 112 and the connecting column 111 can be assembled in advance and then installed in the through hole 102, thereby improving the convenience of assembly.

[0036] In this embodiment, in order to facilitate the processing of the connecting piece 220, the connecting piece 220 includes a main body 223, which is fixedly connected to the bracket 210. One end of the connecting leg 221 is molded with the main body 223, and the other end extends outward, and the abutting portion on each connecting leg 221 is bent and set according to a predetermined position.
