Seeing also first figure and second figure, is known signal shielded box structure decomposition map and combination schematic diagram, as shown in the figure:
Known signal shielded box 1 mainly is made up of a lid module 11, a casing module 12 and a base 313, wherein, the have drawn from aluminium alloy plate body of nine to 12 kinds of different sizes of the combination of this lid module 11, casing module 12 and base 313, after raw material processing, welding, finishing, the processing of CNC composition surface, surface treatment, application and check, finish the manufacturing of a signal shielded box, and be the design of a miter by the composition surface 14 of lid module 11 and casing module 12, the person of being easy to use uses.But this structure contains following shortcoming:
1, the processing of CNC composition surface is consuming time: because composition surface 14 is designs of a miter, must have at miter under the situation of certain adaptation, construction must be accurate and fine and smooth, causes the difficult and consuming time of construction.
2, can not change impaired plate body separately, cause the wasting of resources: form lid module 11 and casing module 12 because this each aluminium alloy plate body welds respectively,, cause the wasting of resources so when generation is impaired, impaired plate body can not be changed separately.
3, complex structure is difficult for the stock: of a great variety owing to the combination of lid module 11, casing module 12 and base 313 is drawn materials from the aluminium alloy plate body of nine to 12 kinds of different sizes, be difficult for the stock.
4, welding application increases cost: because welding respectively, this aluminium alloy plate body forms lid module 11 and casing module 12, thus need through the application step to reach aesthetic in appearance, also thereby the increase cost.
Summary of the invention
The purpose of this utility model is intended to overcome the shortcoming of known signal shielded box, provide a kind of utilize simple design reach assembling easily, stock's materials and parts signal shielded box few and with low cost.
The utility model comprises at least: a loam cake, a casing that loam cake can be covered on it, and loam cake and this casing are combination modules.
Described loam cake can be combined by a top board, a gang form and a base plate;
Described casing can be combined by a top board, a combination module and a base plate;
Described gang form is to be combined by some side plates and some set squares;
The top board bottom surface of described loam cake is provided with a sealing, and plate top surface is provided with a sealing;
The top board bottom surface of described casing is provided with a sealing, and plate top surface is provided with a sealing;
One end of the side plate of described gang form is provided with a raised line, and the other end is provided with a groove.
Owing to adopt said structure, the utility model composite type signal isolates its case lid and this casing is a combination modular structure, so as to assembling easily, reaches stock's materials and parts order few and with low cost.Effectively overcome existing signal shielded box CNC composition surface processing consuming time, can not change impaired plate body separately, complex structure is difficult for stock, the big defect of insufficient of welding painting cost.
