The rack trough
Technical field
The utility model relates to depositing the rack technical field of main frame, control appliance etc., is specifically a kind of rack trough.
Background technology
Existing rack trough generally comprises U-lag and cover plate; the opening portion snapping of cover plate and U-lag; thereby form the tubulose wire casing; cover plate plays a protective role; due to said structure pick and place cable, when maintenance cable etc. operates cable; all need to pull down described cover plate fully, so said structure is comparatively loaded down with trivial details, inconvenient when carrying out the cable operation.
The utility model content
The technical problems to be solved in the utility model is, provide a kind of when carrying out the cable operation rack trough comparatively simply and easily.
The technical solution of the utility model is, the utility model rack trough, and it comprises U-lag and cover plate, one side of cover plate one side and U-lag opening is hinged, the removable snapping of another side of another side of cover plate and U-lag opening.
after adopting said structure, the utility model compared with prior art, have the following advantages: because one side of cover plate one side and U-lag opening is hinged, the removable snapping of another side of another side of cover plate and U-lag opening, like this, after removing snapping, cover plate is rotated around one side of U-lag opening, thereby open cover plate conveniently to carry out the cable operation, after the cable operation is completed, the backward rotation cover plate also finally makes the another side snapping of another side of cover plate and U-lag opening close the purpose of cover plate with realization, said process, it is the cover plate opening-closing process, when cable operates, cover plate does not need to pull down fully, so the utlity model has when carrying out the cable operation comparatively simple, advantage easily, and efficient is high.
As improvement, hinged the referring in one side of described cover plate one side and U-lag opening, one side along the U-lag opening sequentially arranges at least two hinges, wherein one page plate of each hinge all is connected with cover plate one side, one side wherein another page plate of each hinge all with being connected of U-lag opening, because hinge structure is simple and reliable, be easy to make, cost is lower, and is easy for installation, so more be conducive to the raising of enforcement of the present utility model and performance.
