Description

Technical Field

[0001] This utility model relates to a general-purpose sheet metal protection accessory, specifically, a general-purpose sheet metal protection functional module. Background Technology

[0002] Sheet metal protective panels sometimes require observation windows, access doors, or mouse / keyboard trays. Currently, the most common practice during installation is to design these features as an integral part of the sheet metal protective panel at the required locations. While the methods for creating observation windows, access doors, and mouse / keyboard trays entirely through sheet metal molding vary from company to company, errors or changes are inevitable during each design communication and final use. When errors occur or changes are needed, the integrated sheet metal protective panel becomes unusable, leading to the entire protective panel being scrapped or returned to the factory for modification. This not only wastes materials but also makes it difficult to respond promptly to user changes. Utility Model Content

[0003] The purpose of this utility model is to provide a universal sheet metal protection module to solve the problems mentioned in the background art.

[0004] To address the aforementioned issues, a universal sheet metal protection module is provided, comprising a sheet metal protection panel with an installation opening. A sheet metal frame is installed in the installation opening, and several fixing clips are arranged around the perimeter of the sheet metal frame. The fixing clips are secured to the sheet metal protection panel by set screws, thus fixing the sheet metal frame to the sheet metal protection panel. The sheet metal frame is composed of several four-fold basic profiles and several combined frames. The four-fold basic profiles are generally shaped like a "Z" and include inner and outer plates arranged parallel to each other. One end of the inner and outer plates is fixedly connected by a connecting plate. The length of the inner plate is shorter than the length of the outer plate. Several square modular holes and bolt holes are provided on both the inner and outer plates, and these square modular holes and bolt holes are arranged alternately.

One end of the inner plate and the outer plate are inserted into this space. The outer card plate and the inner card plate are set inside the observation module profile. The side of the inner card plate near the middle connecting plate is fixedly connected to the side of the inner observation plate near the bottom observation plate, and the side of the observation card plate near the bottom observation plate is fixedly connected to the side of the outer card plate near the middle connecting plate.

The access door 7 is a product that can be purchased on the market. Double doors, single doors or hatch covers can be installed according to the specific use on site.

[0054] Example 3

[0055] Please refer to Figures 14-20The combined frame consists of human-computer interaction module profile 4, which is formed by bending a single sheet metal piece. The mounting frame of this solution is composed of four human-computer interaction module profiles 4. Each human-computer interaction module profile 4 includes an interactive base plate 41. An interactive outer plate 46 is vertically fixed to one side of the interactive base plate 41, and an interactive card plate 47 is vertically fixed to the other side of the interactive outer plate 46. The interactive card plate 47 is positioned above the interactive base plate 41, i.e., on the side of the interactive outer plate 46 closest to the interactive base plate 41. An interactive vertical plate 42 is vertically fixed to the other side of the interactive base plate 41, and an interactive inner extension plate 43 is vertically fixed to the other side of the interactive vertical plate 42. The interactive inner extension plate 43 and the interactive card plate 47 are located on the same side of the interactive base plate 41. The interactive inner extension plate 43 is positioned on the side of the interactive vertical plate 42 furthest from the interactive base plate 41. An interactive inner vertical plate 44 is vertically fixed away from the interactive base plate 41. An interactive inner plate 45 is vertically fixed to one side of the interactive inner vertical plate 44. The interactive inner plate 45 is positioned above the interactive inner extension plate 43, i.e., the interactive inner extension plate 43 and the interactive inner plate 45 are on the same side of the interactive inner vertical plate 44. A gap is left between the interactive card plate 47 and the interactive inner plate 45 for placing the four-fold base profile 1. The vertical distance between the ends of the interactive inner plate 45 and the interactive card plate 47 is the same as the vertical distance between the outer surfaces of the inner plate 11 and the outer plate 12. The difference in distance between the interactive inner plate 45 and the interactive card plate 47 from the interactive base plate 41 is the same as the installation spacing. The side of the outer card plate 14 near the middle connecting plate 13 and the side of the interactive card plate 47 near the interactive base plate 41 are fixedly connected. The side of the inner card plate 15 near the middle connecting plate 13 and the side of the interactive inner plate 45 near the interactive base plate 41 are fixedly connected.

[0056] Meanwhile, a hinge interface 48 is opened in the middle of the two human-computer interaction module profiles 4 opposite to the mounting frame. The hinge interface 48 is opened at the connection position of the interactive inner panel 45 and the interactive inner vertical panel 44. When the installer is installing, the partition 81 is fixed inside the connecting frame. The partition 81 is installed on the inner side of the human-computer interaction module frame 4, so that the sheet metal frame forms a closed whole. One end of the keyboard tray 8 is fixed to the mounting frame through the hinge bracket. The hinge bracket is installed in one of the hinge interfaces 48. The keyboard tray 8 is set as a flip-plate design that can be opened and closed from 0° to 90°. Then, one end of the connecting frame is passed through the mounting opening and connected with several fixing buckles 9.

[0057] It should be emphasized that when the fixing buckle 9 fixes the four-fold base profile 1 and the transparent cover plate 6, it uses the insertion and cooperation of the inclined plate and the square modular hole 16. The inclined plate blocks the square modular hole 16 to fix the four-fold base profile 1 and the transparent cover plate 6 in the designated position.

[0058] In summary: By combining the four-fold basic profile 1 with different shaped combination frames, different sheet metal frames can be formed to install the observation window, inspection door 7, and mouse / keyboard, eliminating the hassle of one-piece sheet metal protection processing. At the same time, during installation, only holes need to be drilled at any position on the sheet metal protection, allowing the installation of the observation window, inspection door 7, and mouse / keyboard to be adjusted according to the on-site requirements of the sheet metal protection, thus improving the flexibility of sheet metal protection installation.

[0059] This device can adapt to any sheet metal protection requirements for observation, maintenance, and human-machine interaction, and it is quick to install. It is not limited to any specific manufacturer and can be installed at any designated location on the sheet metal protection, making it highly versatile. It saves design time and avoids the error rate of non-standard designs. It does not involve dismantling or replacement, making it more suitable for the practical needs of key industrial nodes. It does not require prior system design, especially for the sheet metal external protection of large-scale automated production lines, which can be arbitrarily arranged according to needs at the end of equipment commissioning.
