Description

Technical Field

[0001] The utility model relates to the technical field of industrial computer dust prevention, in particular to a ventilation and dust prevention device for an industrial computer. Background Art

[0002] Industrial computers are a small category of computers. Due to the large number of industrial sites in the application field, the single performance of the product, the requirement for stability, and the unattended functions, the laptops used in special operation scenarios such as industry are generally specially customized. The industry commonly calls them reinforced laptops. They are somewhat different from the conventional laptops we have seen. The interface may be more complicated, the size is slightly larger, and the weight is slightly heavier. However, the protective design of computers is more important in industrial environments. Some existing industrial computers use cooling fans in the host, but in order to ensure air intake, only simple through holes are opened at the ventilation holes, and no dustproof design is done. This causes external dust to enter the computer from the ventilation holes, resulting in excessive dust accumulation inside the computer, affecting the performance of the internal electronic components. Therefore, those skilled in the art provide a ventilation and dustproof device for industrial computers to solve the problems raised in the above background technology. Utility Model Content

[0003] The utility model aims to provide an industrial computer ventilation and dust prevention device to solve the problems raised in the above background technology.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A ventilation and dustproof device for an industrial computer comprises a computer body, wherein an operation panel is rotatably connected to the side of the computer body, a control key area and an interface area are arranged on the surface of the operation panel facing the computer body, a display screen is installed on the surface of the computer body facing the operation panel, a heat dissipation window is opened on the side of the computer body, fixed transverse pieces are fixedly connected to the inside of the heat dissipation window at equal intervals, a heat dissipation fan is installed inside the computer body, the heat dissipation fan is located on the inner side of the heat dissipation window, and a dustproof mechanism is arranged between the heat dissipation window and the heat dissipation fan.

[0006] As a further solution of the utility model: the dustproof mechanism includes a connecting frame, which is frame-shaped and slidably connected to the inside of the computer body. The inside of the connecting frame is equidistantly and laterally fixed with baffles, which are located on the inner side of the fixed transverse piece and are arranged in close proximity to the fixed transverse piece. The spacing between adjacent baffles is equal to the height of the fixed transverse piece, the height of the baffle is equal to the spacing between adjacent fixed transverse pieces, and the height of the baffle is not greater than the height of the fixed transverse piece.

[0007] As a further solution of the utility model: a telescopic rod is installed inside the computer body, and a driving end of the telescopic rod is fixedly connected to the bottom of the connecting frame.

[0008] As a further solution of the utility model: a mesh plate is slidably installed inside the computer body, the mesh plate is located on a side of the cooling fan away from the cooling window, and the upper end of the mesh plate passes through the upper part of the computer body.

[0009] As a further solution of the utility model: an opening handle is fixedly connected to the surface of the operating panel away from the computer body, an opening groove is provided inside the opening handle, a foot is fixedly connected to the lower surface of the computer body, and the height of the opening handle is equal to the distance from the lower surface of the operating panel when it is laid flat to the bottom surface of the foot.

[0010] As a further solution of the utility model: a placement cavity is opened on the surface of the operation panel close to the computer body, a support block is fixedly connected to the corner of the placement cavity, a magnet is embedded and fixed inside the support block, iron sheets are embedded and fixed at the four corners of the surface of the cover plate, and the sum of the height of the support block and the thickness of the cover plate is equal to the depth of the placement cavity.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] By setting an adjustable baffle, when the industrial computer needs to be used, the connection frame can be controlled to move by the telescopic rod, so that the baffle and the fixed horizontal plate overlap, so that the baffle no longer blocks the gap of the fixed horizontal plate, and the air exchange inside and outside the computer body is guaranteed. When the industrial computer is not in use, the baffle blocks the gap of the fixed horizontal plate, which can block external dust and prevent dust from entering the interior of the industrial computer body. By setting a mesh plate, external dust is further isolated to prevent dust from entering and contacting the electronic components inside the industrial computer body, thereby strengthening the protection of the electronic components inside the industrial computer body. The mesh plate can be disassembled and can be cleaned regularly to ensure the cleanliness of the inside of the computer body. BRIEF DESCRIPTION OF THE DRAWINGS
