Together.
Such structure can guarantee that card and positioning port have enough contacts area, so as to ensure its connective stability.
In above-mentioned chromatographic analyzer of liquid phase in the bindiny mechanism of spacer and positioning strip, described spacer is plastics
Material.
The spacer of plastic material is by Shooting Technique energy one-shot forming, and cost is than relatively low.
In above-mentioned chromatographic analyzer of liquid phase in the bindiny mechanism of spacer and positioning strip, the width of described positioning recess
Degree is less than positioning port width and when spacer and positioning strip are connected, and above-mentioned positioning recess is located on the inside of positioning port.
Such structure positioning bar can cover positioning recess, it is ensured that the connective stability between spacer and positioning strip.
In above-mentioned chromatographic analyzer of liquid phase in the bindiny mechanism of spacer and positioning strip, have on the inside of the positioning port
The contact site of frictional force can be increased, above-mentioned card leans under the elastic force effect of itself with contact.
The frictional force between spacer and positioning strip can be improved in the presence of contact site, makes spacer stable with positioning strip
Connection.
In above-mentioned chromatographic analyzer of liquid phase in the bindiny mechanism of spacer and positioning strip, the depth of the positioning recess
More than positioning port depth and when spacer and positioning strip are connected, positioning port is exposed in above-mentioned positioning recess part.
Once after spacer and the insertion of positioning strip aligned in position, just part exposes above-mentioned positioning recess.Conversely, not right
During neat insertion, positioning recess can deviate positioning strip, user can be made to understand spacer and positioning strip in time by such structure
Link position it is whether correct.
In above-mentioned chromatographic analyzer of liquid phase in the bindiny mechanism of spacer and positioning strip, the positioning strip and shackle member
One group of clamping unit is formed, the quantity of the clamping unit is 2-5.
In above-mentioned chromatographic analyzer of liquid phase in the bindiny mechanism of spacer and positioning strip, the quantity of the clamping unit
For two.
Multiple clamping units can further improve the connective stability between positioning strip and spacer.
Compared with prior art, in this chromatographic analyzer of liquid phase the bindiny mechanism of spacer and positioning strip can make spacer with
Positioning strip is stably connected with, and not only connective stability is high, and it realizes that therefore, its structure is also simply by single shackle member
It is fairly simple.
