Detailed description of the invention
The detailed description of the invention of the present invention is made a detailed explanation by 1-4 below in conjunction with the accompanying drawings.
Embodiment: the clamping device of a kind of micro-fluidic chip, its structure specifically include that liquid injection port 1, microfluidic control chip 2,
Device pedestal 3, chip guide rail 4, stent holder 5, pull button 6, support guide 7, fixing bolt 8, universal slide block 9, slide block are fixed
Blank pipe 15, cradling piece 16 in bolt 10, pole 11, spacing granule 12, connector 13, double-deck sucker 14, connector,
On described device pedestal 3, four limits are provided with support guide 7, support guide 7 is mounted with stent holder 5, passes through
Stent holder 5 makes support guide 7 be hinged with cradling piece 16；Cradling piece 16 is provided with multiple universal slide block 9, universal slide block
Being installed with pole 11 in 9, pole 11 1 end is provided with bayonet socket, and cradling piece 16 top is provided with spacing granule 12；On stent holder 5
Being provided with fixing bolt 8, universal slide block 9 is provided with slide block and fixes bolt 10；Chip guide rail 4 is provided with a pair pulls button 6；
Liquid injection port 1 in microfluidic control chip 2 is provided with connector 13, and connector 13 end is provided with double-deck sucker 14.
Described device pedestal 3 bottom surface is transparent baffle.
The described button 6 pulled is pulled for spring and is buckled.
Whole operating process is done the most detailed step below illustrate: because its liquid injection port 1 of microfluidic control chip 2 has
Multiple, and every kind of different its aperture position of microfluidic control chip 2 is all uncertain, so its support should be the most
Become, and its fixed coordinates can be arbitrary.
Clamping work starts: first takes one piece of microfluidic control chip 2, pulls open button 6, is placed in device pedestal 3,
Then will pull button 6 and buckle fixing.It is actually needed according to microfluidic control chip 2 and assigns the quantity of connector 13 to carry out assigning complete,
Take a ruler and measure coordinate points, the fixing bolt 8 on stent holder 5 is unscrewed so that corresponding two cradling pieces 16 are permissible
Move on support guide 7 according to the coordinate points that ruler determines, can determine that the coordinate of horizontal plane after moving, now tighten and prop up
Fixing bolt 8 on frame holder 5.
Then, unscrew the slide block on cradling piece 16 and fix bolt 10 so that can glide on cradling piece 16 to slide block 9
Dynamic, pole 11 can pull and push with all directions.Because possible connector 13 has multiple, therefore pole 11 can be there is at same horizontal plane
During upper support, the situation that two bars intersections crash occurs, and slide block 9 can slide up and down and create the multilevel layout of clamping, real
Show three-dimensional clamping；After level, vertical two direction Coordinates calibrations, tighten slide block and fix bolt 10, it is achieved clamping purpose.
The effect of chip guide rail 4 is the adaptability size adjusting and disposing microfluidic control chip 2, in order to obtain good fixing
Effect；Pull button 6 to pull for spring and to buckle to adapt to the various various thickness of microfluidic control chip 2；The spacing granule 12 on cradling piece 16 top
Effect is to prevent universal slide block 9 from skidding off cradling piece 16；Device pedestal 3 bottom surface is that transparent baffle its purpose is to facilitate liquid stream
To observation.
Connector 13 end is provided with double-deck sucker 14 effect two: one: seals liquid injection port 1 and connects with connector 13；
Its two: position fixation.Its structure is: double-deck sucker 14 has inside and outside two-layer, when double-deck sucker 14 works, inside and outside it in two-layer
Between position be in hollow, it is achieved attracting purpose.
