In, the limited cover bolt for being symmetricly set on injection needle both sides is vertically equipped with pin fixed seat, it is arranged with down on the limited cover bolt
The elastic component that end contacts with pin fixed seat upper surface.
The pin guide holder outside is provided with pilot sleeve.
The anti-pollution eluting pin for reaction cup cleaning that this utility model is provided, it is simple structure, easily operated, it is provided with
Buffer gear, can fully imbibition, effectively prevent needle body pollution, crystallize.Between eluting pin of the present utility model is included side by side
Every the injection needle and aspirating needle that arrange, in injection process, two pins can be fully avoided mutually to pollute and injection needle wall hanging liquid knot
It is brilliant；Liquid injection port is located at vertical direction, cleanout fluid can be filled in reaction cup and effectively prevents liquid from spilling；Liquid sucting port surrounding is opened
Imbibition groove is provided with, aspirating needle fully imbibition is enable；Meanwhile, when multiple pins are applied in combination, due to reaction cup and whole dress
There is tolerance between the depth put, therefore in the presence of elastic component on limited cover bolt, eluting pin can be in limited cover bolt
Stroke range in move up and down, it is ensured that each pin can touch reaction cup cup bottom.

Specific embodiment
As Figure 1-4, the anti-pollution eluting pin for reaction cup cleaning described in the utility model, including pin fixed seat
1st, pin guide holder 2 and the eluting pin of pin fixed seat 1 and the center of pin guide holder 2 is socketed in, eluting pin includes and cleanout fluid with pressure
Injection needle 3 that container is connected and the aspirating needle 4 being connected with vacuum pump, injection needle 3 is shorter than aspirating needle 4, can fully avoid note
Liquid pin 3 submerges below cleanout fluid liquid level and is contaminated.Injection needle 3 and aspirating needle 4 are spaced vertical needle body, and its end is divided
Do not offer liquid injection port 5 straight down and liquid sucting port 6.Interval offers at least one imbibition on the pin wall of the surrounding of liquid sucting port 6
Groove 7（See Fig. 4）, imbibition groove 7 can select suitable quantity and shape according to actually used situation, can avoid liquid sucting port
6 with reaction cup bottom suppress extremely, can fully carry out imbibition and be defined.Injection needle 3 and the middle position of aspirating needle 4 are provided with connection two
Person, both are made to keep the separation fixture 8 of released state.Anti-pollution eluting pin fluid injection liquid with said structure flow direction is vertical
Downwards, even if needle body leaves completely reaction cup, can still fill reaction cup, therefore the cleaning way of marginal not liquid side imbibition can be adopted,
The concentration of liquid in diluting reaction cup, reduces needle body pollution；Secondly as injection needle 3 and aspirating needle 4 are vertical needle body, therefore
Liquid flowing is more smooth, and liquid injection port 5 and liquid sucting port 6 will not occur retardance and condense, and fluid injection liquid vertical is dirty, can be prevented effectively from
Liquid spills the phenomenon outside reaction cup in injection process, easy to operate, it is easy to grasp；Additionally, two pins and separate, Ke Yichong
It is divided to and avoids two pins from mutually polluting and the crystallization of injection needle wall hanging liquid.
As shown in figure 3, injection needle 3 and the root of aspirating needle 4 fix the pin fixed seat 1 and pin guide holder 2 in integrated setting
In, the limited cover bolt 9 for being symmetricly set on the both sides of injection needle 3 is vertically equipped with pin fixed seat 1, it is arranged with down on limited cover bolt 9
The elastic component 10 that end contacts with the upper surface of pin fixed seat 1, the lower end of limited cover bolt 9 is fixed with the eluting arm 11 for placing eluting pin and is connected
Connect.The pilot sleeve 12 for being set in the outside of pin guide holder 2 is provided between pin fixed seat 1 and eluting arm 10.Cover anti-pollution washing more
Run-bake-needle fault is arranged on eluting arm 11 simultaneously when, due to there is tolerance between reaction cup and the depth of whole device, can not reach
All eluting pins are contacted with reaction cup cup bottom simultaneously.When eluting arm 11 continues to move down, for touching reaction cup cup bottom first
Aspirating needle 4, aspirating needle 4 and the relative elutropic arm of pin fixed seat 1 being connected with aspirating needle 4 are moved up, positioned at the He of limited cover bolt 9
Elastic component 10 between pin fixed seat 1 is compressed；When elastic component 10 is fully compressed, edge and limited cover bolt 9 in pin fixed seat 1
When lid bolt contacts, single eluting pin anticollision adjusting means is reached the limit values.In this trip, due to the work of above-mentioned buffer structure
With the needle point of aspirating needle 4 is contacted all the time with reaction cup cup bottom, and avoid hard collision, the dependent part such as effective protection aspirating needle 4
Part.Above-mentioned two sets of limited cover bolts 9 and elastic component 10 are symmetricly set on eluting pin both sides, and the length of pilot sleeve 12 can prolong always
Reach the position of pin fixed seat 1, it is ensured that aspirating needle 4 is more vertically and smooth in cushion stroke, simultaneously as pilot sleeve
12 are vertically directed effect, it is not necessary to require that elastic component 10 provides thrust and keeps vertical ensureing aspirating needle 4, therefore can select
The elastic component 10 of less elastic force, can avoid the frequent haptoreaction cup cup bottom of aspirating needle 4 from occurring additionally, the elastic force of elastic component 10 is less
Fierce collision.
