Abstract
The invention discloses a base of a rear projection box. The base comprises a base frame, wherein two longitudinal sections, four transverse sections and four longitudinal installation upright posts are arranged on the base frame; two installation upright posts are arranged between two transverse sections on the same vertical plane; a built-in cabinet is formed by the four installation upright posts; the side face of the base frame is provided with an air switch; an external power wire is connected with internal equipment through the air switch; and a natural heat dissipation hole is formed on a rear sealing plate of the base frame. The base meets the installation size requirement of the conventional 19-inch standard cabinet, is compatible with the conventional base, and can be added or saved at any time according to the field actual condition.
Description
Technical field
The present invention relates to the field of installing and using of 67 cun rear-projection casees, be specifically related to a kind of rear-projection case base.
Background technology
At present, 67 cun rear-projection casees in use often need be used opertaing devices such as node machine, processor, matrix.In common use, these opertaing devices need 19 cun racks of other configuration standard, together use with the rear-projection case.
In actual use, often face the situation that insufficient space is installed and used in old place.Because the space requirement of system's rear-projection case is bigger, the same place that causes 19 cun standard cabinets to place.If be not placed on same place, when 19 cun standard cabinets and rear-projection case standoff distance are far away excessively so, will cause transmission line long, signal attenuation is serious; Perhaps transmission line is externally in the transmission course of place, and it is too much excessive to be subjected to interference source such as high-voltage ac power, signal serious interference and cause projector to show that operation is undesired.
Common interim workaround is for directly to be placed on the base internal ground to opertaing device, and this method drawback is more: dustproof, poor radiation, not attractive in appearance, to place material lack of standardization etc.
Summary of the invention
The present invention is in order to overcome the deficiency that above prior art exists, a kind of rear-projection case base is provided, and this base not only meets the installation dimension of present 19 cun standard cabinets, and compatible mutually with existing base, can increase at any time or reduce according to on-site actual situations.
Purpose of the present invention realizes by following technical scheme: this rear-projection case base, comprise bedframe, it is characterized in that: described bedframe is installed two longitudinal profiles, four horizontal section bars and four column is installed longitudinally, two installation columns are installed between two horizontal section bars of same vertical plane, article four, the installation column constitutes built-in rack, the side of bedframe is equipped with air switch (avoiding producing interference with internal unit), external power cord connects internal unit by air switch, offers the natural heat dissipation hole on the back shrouding of bedframe.
Described internal unit comprises node machine, processor, matrix, and node machine, processor, matrix are directly installed between four described installation columns.
Described node machine, processor, matrix are directly installed between four installation columns by M6 screw, buckle or the mode of inlaying.
Described internal unit comprises switch, transformer, because switch, transformer size are less, switch, transformer are installed between four described installation columns by pallet or carriage.
Described pallet or carriage are installed between four installation columns by M6 screw, buckle or the mode of inlaying.
Described installation column adopts 1.5mm cold-reduced sheet bending and molding, and plating blue zinc in surface is installed column and is provided with a standard M6 grounding nut mounting hole, in attractive in appearance, guarantees good ground connection performance requirement.
In concrete use, opertaing devices such as the node machine that the rear-projection case adopted, processor, matrix are the following power of 300W through the statistics major part, thus aspect heat radiation based on natural heat dissipation, by afterwards offering the louvre natural heat dissipation on the shrouding.When big or thermal source was concentrated when internal unit power, then front or reverse side were equipped with 120 fans in the bedframe, and fan connects air switch, by the fan active heat removal.The installation site will meet the installation dimension of 120 fans.
Described base is the base of 67 cun rear-projection casees, and the bottom of bedframe is equipped with eight identical lower margins.The weight of considering built-in device can increase the stressed of base, base is increased to eight lower margins from four original lower margins, four lower margins that increase newly are directly installed on the bottom of built-in rack aluminium section bar, disperse, bear the stressed of base, guarantee the structural strength of total system.Adopt identical ground leg structure, integrally-built installation, fixed form are constant, reduce cost.
Dustproof protection against rodents bottom sealing plate is installed below the described bedframe.
For realizing the present invention better, according to existing line footpath and quantity, and present general mould, described bottom sealing plate both sides are provided with the easy abate cable hole of diameter 80mm.Can use according to the position of ground trough is convenient in actual use.
The present invention has following advantage with respect to prior art:
This rear-projection case base improves existing base, has increased by 19 cun built-in standard cabinets, designs according to international standard IEC297 " 482.6mm (19in) series mechanical physical dimension ", at the general international standard rack of the inner installation of base.The present invention only increases six section bars and four installation columns newly, and mounting means, erecting tools and old base are identical, only needs singlely to carry general utility tool operation and can finish installation, and is simple in structure, easy for installation.Can increase according to actual needs or reduce, reduce cost.
This base only increases the M6 mounting hole newly in production and processing, it is promptly scalable that existing old base only needs to increase the M6 mounting hole, and section bar and column are installed on the base by the M6 screw, and the M6 hole of increase is very little to the overall construction intensity influence, and outward appearance does not have difference.The material that is adopted is existing material, and the general 19 cun racks of mounting means, and existing project installation personnel all do not need extra training to use by direct control.
When internal unit when being a plurality of, internal unit adopts the mode of stack up and down to install so, such structure conserve space, and a plurality of internal unit is independent of each other.
