Description

Technical Field

[0001] The utility model relates to the technical field of industrial control computers, in particular to an anti-electromagnetic interference cover for an industrial control computer. Background Art

[0002] An industrial computer (IC) is a ruggedized, enhanced personal computer designed for process control applications in harsh environments (such as strong electromagnetic interference, severe vibration, high dust levels, and wide temperature ranges). When in use, an IPC must be resistant to strong magnetic interference when encountering equipment with electromagnetic fields. In environments without electromagnetic fields, a well-ventilated environment is beneficial for its use. However, because IPCs require a confined space to resist strong electromagnetic interference, their heat dissipation and ventilation cannot effectively prevent the hazards of strong electromagnetic interference. Severe vibration can also damage components within the IPC, and the enclosed enclosure design makes maintenance extremely inconvenient, impacting subsequent maintenance and use. Based on this, an IPC anti-electromagnetic interference enclosure is proposed. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] Reference Figure 1-7 A cover body for preventing electromagnetic interference of an industrial computer comprises a cover body 1 and a cover cover 2 detachably connected to the cover body 1. A vent 3 is provided on one side of the cover body 1, and a pull-out frame 4 is provided in the vent 3. Furthermore, a filter screen 14 is provided in the vent 3. A connecting groove 15 is provided on the outer wall of the cover body 1, and a pull ring 16 is fixedly connected to one end of the pull-out frame 4.

[0025] It should be noted that the filter 14 is installed in the drawer frame 4 , and the drawer frame 4 is pulled out through the pull ring 16 to facilitate replacement of the filter 14 .

[0026] The inner walls on both sides of the cover body 1 are rotatably connected to a rotating shaft 5, a baffle plate 6 is provided under the cover 2, and the rotating shaft 5 is provided with a flip assembly. Furthermore, the flip assembly includes a crank 17 fixedly connected to the rotating shaft 5, and the other end of the crank 17 is fixedly connected to a flip connecting rod 18, and the flip connecting rod 18 is rotatably connected to a first connecting plate 19, and the first connecting plate 19 is fixedly connected to the bottom end of the baffle plate 6.

[0027] It should be noted that when electromagnetic interference occurs, the vent 3 can be covered by flipping the shielding plate 6 to form a closed space in the cover body 1, thereby effectively avoiding electromagnetic interference.

[0028] The flip assembly is fixedly connected to the shielding plate 6. Furthermore, a second connecting plate 20 is fixedly connected to the bottom of the shielding plate 6. The second connecting plate 20 is rotatably connected to a rolling wheel 21. A slope slide 22 is provided at the bottom of the rolling wheel 21. The slope slide 22 is fixedly connected to the inner wall of the cover body 1.

[0029] A plurality of wiring holes 9 are provided on the inner wall of one side of the cover body 1. A torsion spring 10 is fixedly connected to the bottom end of the cover body 1. The other end of the torsion spring 10 is fixedly connected to a connecting rod. One end of the connecting rod is rotatably connected to a connecting column 12. Furthermore, the connecting column 12 is fixedly connected to a first gear 23. The first gear 23 is meshedly connected to a second gear 24. The second gear 24 is fixedly connected to a rotating knob 25.

[0030] It should be noted that the torsion spring 10 reduces vibrations caused by other mechanical operations when the mounting base 13 is lowered to the bottom end of the cover 1 .

[0034] The utility model forms a closed structure by installing the cover body 1 and the cover cover 2. Since both materials are metal, they can effectively resist electromagnetic interference. A shielding plate 6 is placed on the inner side of the bottom of the cover cover 2. When electromagnetic interference is generated by surrounding machines, the shielding plate 6 can be turned 90 degrees by rotating the rotating shaft 5 outside the cover body 1 to block the vent 3 of the cover body 1, so that the cover body 1 is completely sealed, effectively resisting electromagnetic interference and protecting the safety of internal devices.

[0035] When the industrial computer fails, the shielding plate 6 is flipped 90 degrees, the cover 2 is removed, and the knob 25 is turned to engage the second gear 24 with the first gear 23, and the mounting base 13 is raised to a height that is convenient for the staff to perform maintenance operations, saving manpower and providing convenience for inspection and maintenance.
