Problems solved by technology

[0003] In recent years, the working environment of the industrial computer is relatively complicated, and because the components of the industrial computer have a high degree of precision, there are high requirements for heat dissipation, dustproof and electromagnetic shielding, and the replacement of the dustproof net is more frequent
The heat dissipation dust cover of the chassis of the traditional industrial computer is mostly fixed with the box by screws, and the daily maintenance and disassembly are more complicated. Some dust covers are made of plastic, and the electromagnetic shielding performance is poor.

Embodiment 1

[0037] Such as figure 1As indicated in , since the chassis of the industrial computer needs to dissipate heat, the heat dissipation port will be set to dissipate heat from the chassis, and the dust-proof measures for the heat dissipation port will directly affect the service status and life of the industrial computer, so dust-proof parts are usually installed on the heat dissipation port 300 is used for dust prevention. As time goes by, the dust-proof component 300 will need to be replaced or cleaned due to the accumulation of dust. Therefore, in order to facilitate the disassembly, replacement and maintenance of the heat-dissipating and dust-proof component 300 on the chassis of the industrial computer, this embodiment Among them, the dustproof device is used on the industrial control computer case, and the device includes a case panel 100 , a turning assembly 200 and a dustproof part 300 . Specifically, the chassis panel 100 is provided with a heat dissipation hole 101 of th...

Embodiment 2

[0039] Such as figure 2 Indicated in, and refer to figure 1 As shown in the figure, in order to realize the automatic reset of the turning assembly 200 and the closing under force in the initial state, the turning assembly 200 in this embodiment further includes a turning plate 201 , a turning shaft 202 and a turning spring 203 . Specifically, the chassis panel 100 is provided with a heat dissipation hole 101 of the chassis for heat dissipation of the chassis; the flip assembly 200 is arranged in the heat dissipation hole 101 and is hinged between one end and the chassis panel 100, and the heat dissipation hole 101 is turned over by the flip assembly 200. The opening of the cabinet is sealed or opened; and the dustproof part 300 is arranged in the flip assembly 200; it should be noted that it is not difficult to find that the cabinet panel 100 can be arranged on any surface of the cabinet as a closing plate on any face of the cabinet , the general chassis is a regular cuboid...

Embodiment 3

[0041] This embodiment provides a sensor assembly applied to the dust-proof component 300 in the above-mentioned embodiment. By installing a temperature sensor in the dust-proof component 300, the temperature of the chassis is monitored, and an alarm can be issued when the temperature is too high. pass image 3 The indicator light shown in the picture (not shown in the figure) or the existing loudspeaker is used to realize the alarm, which can promptly notify the staff to deal with it, prevent the case from burning out when the temperature is too high, and curb the potential safety hazard of fire. What needs to be explained here is that because the temperature sensor is set in the dust-proof member 300, a large amount of dust will accumulate and affect the performance of the sensor as time goes by. Therefore, in order to facilitate disassembly, replacement or maintenance of the sensor device, to maintain the performance of the temperature sensor , so that the monitoring is mor...

Abstract

The invention discloses a dust-proof device, which comprises a chassis panel, on which a heat dissipation hole of the chassis is arranged for heat dissipation of the chassis; The overturning of the overturning component seals or opens the opening of the heat dissipation hole; and the dustproof part is arranged in the overturning component. The beneficial effects of the present invention are as follows: one is to adopt the structure that a rotary spring is arranged between the rotating shaft and the dust-proof mesh, which is convenient for opening and closing, and is convenient for maintenance. It is made of metal, which can ensure the electromagnetic compatibility performance of the chassis; the third is to properly set up cooling holes, which can not only ensure the heat dissipation requirements, but also ensure the electromagnetic shielding performance of the chassis.

Description
