To realize the assembly of entire firm banking 2, the cabinet 1 that will then amplify is installed in fixing seat, first by two clip assemblies 4
On upper card frame 12 disassemble, the cabinet 1 that will then amplify is put on two lower card frames 13, then upper card frame 12 is installed to down
It when card frame 13, is fastened and fixed by fastening screw 15, two clampings is then carried out according to the length dimension for the cabinet 1 that amplifies and structure
The fastening nut 26 on sliding bar 18 is unscrewed in the adjustment of spacing between component 4, allows slider box 10 sliding along sliding panel 7
It is dynamic, while sliding bar 18 being driven to slide in perforation 25, when two clip assemblies 4 are moved to appropriate position, tighten two
Fastening nut 26 on clip assembly 4, so that two clip assemblies 4 can not continue to move to, overall construction design compact and reasonable, peace
It is more convenient to use for dress, and by structure split type between upper card frame 12 and lower card frame 13 in clip assembly 4, by adjusting
Limited block 17 is inserted into the length in limiting slot 16, and card frame 9 can be allowed to carry out card slot 14 according to the thickness for the cabinet 1 that amplifies
Size changes, while can be according to the adjustment of spacing between the progress of the length for the cabinet 1 that amplifies, effectively between two clip assemblies 4
The scope of application for expanding firm banking 2, so that the various sizes of cabinet 1 that amplifies can be fixed.
The present invention is practical, and overall construction design is ingenious rationally, by the design of firm banking 2 so that the cabinet 1 that amplifies
Installation place it is more convenient securely, effectively avoid Intelligent platform from carrying or amplified cabinet 1 when by external force collision to inside
Damage, while being designed by the overall structure to firm banking 2, not only to amplify between cabinet 1 and firm banking 2
Dismounting it is more convenient, and firm banking 2 can be adjusted according to the actual size for the cabinet 1 that amplifies, it is ensured that amplify case
Performance is firmly installed between body 1 and firm banking 2, expands the use scope of firm banking 2.
The above is only specific embodiments of the present invention, but technical characteristic of the invention is not limited thereto.It is any with this hair
Based on bright, to solve essentially identical technical problem, essentially identical technical effect is realized, made simple change, etc.
With replacement or modification etc., all it is covered by among protection scope of the present invention.
