[0031] Example 1

[0032] See Figures 1-5 This embodiment discloses a specific implementation of an industrial control display screen that is easy to assemble.

[0033] For easy-to-assemble industrial control displays, see [link / reference]. Figures 1-4The system includes a first cavity 1 and a second cavity 2; the first cavity houses a display screen assembly 3, preferably a 21.5-inch display screen; the second cavity 2 houses a display screen switch assembly 4, and the dimensions of the second cavity 2 are 553mm × 60mm × 30mm; the first cavity 1 includes a back cover 11 and a third cavity 5 mounted on the back cover 11, the third cavity 5 housing a PCB assembly 6; the back cover 11 has a cutout portion 111, the cutout portion 111 having three first notches 112, the... The third cavity 5 includes a heat dissipation cover 51, an arc-shaped cover 52, and a top cover 53. The heat dissipation cover 51 is provided with a first L-shaped hook 511 corresponding to the first defect 112. The top cover 53 is provided with a first mounting hole 531 for fastening the PCB assembly 6. The heat dissipation cover 51 is provided with three second defect 512. The arc-shaped cover 52 is provided with a second L-shaped hook 521 corresponding to the second defect 512 at one end. The arc-shaped cover 52 is provided with a second mounting hole 522 at the other end.

[0034] Specifically, see Figures 1-5 The industrial control display screen is divided into a first cavity 1 and a second cavity 2. The first cavity 1 houses the display screen assembly 3, and the second cavity 2 houses the display screen switch assembly 4, allowing the display screen switch assembly 4 to be customized according to the customer's actual needs. The first cavity 1 includes a rear cover 11 and a third cavity 5. The third cavity 5 includes a heat dissipation cover 51, an arc-shaped cover 52, and a top cover 53. The heat dissipation cover 51 is provided with several fins to facilitate heat dissipation. The heat dissipation cover 51 is quickly assembled with the first notch 112 via a first L-shaped hook 511. The arc-shaped cover 52 is concave. The curved surface makes the external dimensions of the third cavity 5 smaller and more aesthetically pleasing. The curved cover 52 is quickly assembled with the second L-shaped hook 521 and the second defect 512, and then fastened to the other end of the curved cover 52 with a screw 7. That is, the curved cover 52 is fastened with a screw 7 and the second mounting hole 522, so that the third cavity 5 can be quickly assembled to the back cover 11 of the first cavity. Moreover, only one screw 7 is visible on the appearance of the third cavity 5, making the appearance more concise and elegant. The top cover 53 is provided with a cantilever 532, and the curved cover 52 transitions from the top cover 53 to the heat dissipation cover 51 in an arc shape.

[0035] See Figures 1-5The display switch assembly 4 includes a start button, a stop button, and an emergency stop button. The display switch assembly 4 and the display assembly 3 are electrically connected via control lines. To facilitate the arrangement of the control lines, two cable receiving cavities 12 are provided within the first cavity 1, and the PCB assembly 6 is disposed between the two cable receiving cavities 12. The first cavity 1 has a first cable hole 13, and the second cavity 2 has a second cable hole 21, which are concentrically arranged. The control lines of the PCB assembly 6 pass through the cable receiving cavities 12, the first cable hole 13, and the second cable hole 21. The second cable hole 21 is electrically connected to the display screen switch assembly 4. During the arrangement of the control line, in order to facilitate the observation and manual arrangement of the control line, the cable receiving cavity 12 is provided with a first transparent window 121 and a second transparent window 122. The first transparent window 121 and the second transparent window 122 are respectively detachably installed in the cable receiving cavity 12. When it is observed that the control line passes through the first transparent window 121 or the second transparent window 122, the first transparent window 121 or the second transparent window 122 can be removed, so that the control line can be further threaded manually so that the control line passes through the larger first cavity 1.

[0036] See Figures 1-5 Locking screws 23 are respectively provided at both ends of the bottom plate 22 of the second cavity 2. The first cavity 1 and the second cavity 2 are locked together by the locking screws 23. Since the locking screws 23 are located at the bottom plate 22, the locking screws 23 are not easy to be found, which further increases the overall aesthetics of the industrial control display screen.

[0037] See Figures 1-5 The bottom plate 22 of the second cavity 2 is provided with an L-shaped support 24, and a workbench 25 is provided on the L-shaped support 24. The L-shaped support 24 and the workbench 25 form a support frame for the industrial control display screen. Users can place items such as keyboards and notebooks on the workbench 25.
