[0033] The present utility model provides an industrial control equipment installation component 1, and the installation component 1 is used to install and fix an industrial control equipment 2 on an installation panel 3. The industrial control equipment 2 can be an industrial control equipment such as a touch screen, an industrial tablet computer, an HMI (Human Machine Interface) device, an operation keyboard, etc. The installation panel 3 is usually a sheet metal panel on a device or a cabinet, and the installation panel 3 is provided with an installation window 31 for embedding the industrial control equipment 2.

[0034] Please refer to Figures 1 to 4, in an embodiment of the present utility model, the mounting assembly 1 includes a connecting rod 11 and a mounting screw 12. The connecting rod 11 is mounted on the outer side portion 21 of the rear housing of the industrial control device 2. Specifically, the connecting rod 11 is elliptical with a certain height and has a threaded hole 111. The mounting screw 12 is threadedly connected to the threaded hole 111. The mounting screw 12 can be a cross-head long screw or a flat-head long screw, which is not limited herein. The height of the mounting screw 12 is greater than the height of the connecting rod 11. The mounting screw 12 can move in the threaded hole 111, and the mounting screw 12 can be tightened or loosened. During the tightening process, the bottom of the mounting screw 12 can protrude from the bottom surface of the connecting rod 11. It should be noted that the thread of the mounting screw 12 has an anti-loosening structure 121, and the anti-loosening structure 121 is used to limit the movement range of the mounting screw 12 in the threaded hole 111. Specifically, when the mounting screw 12 is loosened, the mounting screw 12 will gradually withdraw from the threaded hole 111. When it retreats to the position where the anti-loosening structure 121 is located, since the anti-loosening structure 121 cannot move in the threaded hole 11, the mounting screw 12 cannot withdraw further, so that the mounting screw 12 remains on the connecting rod 11 in any state, avoiding the problem of falling.

[0035] In this embodiment, please refer to Figure 5 , the bottom thread of the mounting screw 12 can be embossed to form the anti-loosening structure 121, damaging the bottom thread of the mounting screw 12, and forming at least one embossment 1211 at the bottom thread. The embossment 1211 can be an inclined surface or a flat surface. In other embodiments, please refer to Figure 6 and Figure 7 , a bump 1212 or a snap ring 1213 can also be provided at the bottom thread of the mounting screw 12. The bump 1212 or the snap ring 1213 is the anti-loosening structure 121, and the 1212 or the snap ring 1213 protrudes from the threaded hole 111.

[0036] Please refer to Figures 1 to 4 , in an embodiment, the mounting assembly 1 further includes a rotating shaft 13. The rotating shaft 13 is fixedly arranged on the outer side portion 21 of the rear housing of the industrial control device 2. The rotating shaft 13 is located at one end of the connecting rod 11. Specifically, the rotating shaft 13 can be an internal hexagonal screw, and the internal hexagonal screw fixes one end of the connecting rod 11 on the outer side portion 21 of the rear housing of the industrial control device 2. The mounting screw 12 is located at the other end of the connecting rod 11, and the connecting rod 11 can rotate around the rotating shaft 13 from the first position to the second position.

[0037] Please refer to Figure 2 and Figure 3, when the connecting rod 11 is in the first position, the mounting screw 12 is located in the area of the outer part 21. In this state, the industrial control device 2 can be inserted into the installation window 31 of the installation panel 3 from the front. The outer side of the industrial control device 2 abuts against the front of the installation panel 3, and the installation component 1 protrudes from the back of the installation panel 3. At this time, the connecting rod 11 can be rotated to the second position. Please refer to Figure 4 , when the connecting rod 11 is in the second position, the mounting screw 12 protrudes from the area of the outer part 21, and the bottom of the mounting screw 12 abuts against the back of the installation panel 3. The installation panel 3 is clamped between the industrial control device 2 and the mounting screw 12, so as to fixedly install the industrial control device 2 on the installation panel 3. Similarly, when disassembling the industrial control device 2 from the installation panel 3, loosen the mounting screw 12 and rotate the connecting rod 11 from the second position to the first position.

[0038] In this embodiment, since the thread of the mounting screw 12 has an anti-loosening structure 121, the mounting screw 12 cannot be further withdrawn after retreating to the position where the anti-loosening structure 121 is located, so that the mounting screw can always remain on the connecting rod 11, avoiding the detachment of the mounting screw 12 during the disassembly and assembly of the industrial control device 2. And by installing the installation component 1 on the outer part 21 of the rear shell of the industrial control device 2 as an integral body, the connecting rod 11 can be moved between the first position and the second position by simple rotation, and the disassembly and assembly process of the industrial control device 2 can be completed independently by one person, improving the maintenance convenience.

[0039] In addition, please refer to Figure 1 , in an embodiment, a counterbore 1111 is provided in the screw hole 111 through which the mounting screw 12 passes in the connecting rod 11. The counterbore 1111 is located at one end of the screw hole 111 close to the thread bottom of the mounting screw 12, and the thread bottom of the mounting screw 12 can be received in the counterbore 1111. In this way, it can be ensured that during the movement of the connecting rod 11 between the first position and the second position, the bottom of the mounting screw 12 will not interfere with the installation panel 3.

[0040] Optionally, a positioning member (not shown) is provided on the outer part 21, and the rotating shaft 13 can be fixedly arranged on one side of the positioning member. When the connecting rod 11 is in the second position, the connecting rod 11 abuts against the positioning member.
