Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not making creative work premise
Lower obtained every other embodiment, broadly falls into the scope of this utility model protection.
This utility model provides a kind of clamper for clamping experiment body, refer to Fig. 1 to Fig. 4, new in this practicality
In type first embodiment, this clamper includes that connect holds part 2 and holder 4, and wherein, this holds part 2 has and be oppositely arranged
The first end 200 and the second end 220, hold part 2 tool be resilient such that between the first end 200 and the second end 220 distance adjustable
Joint.This holder 4 includes spaced first clamping part 40 and the second clamping part 42, this first clamping part 40 and first end
200 connect, and this first clamping part 40 is provided with the first inner concave arc surface 400；This second clamping part 42 is connected with the second end 220, and
This second clamping part 42 is provided with the second inner concave arc surface 420；This first inner concave arc surface 400 is oppositely arranged with the second inner concave arc surface 420.
The present embodiment clamper is by being respectively provided with first on first clamping part 40 and the second clamping part 42 of holder 4
Inner concave arc surface 400 and the second inner concave arc surface 420, and the first inner concave arc surface 400 and the second inner concave arc surface 420 that are oppositely arranged are permissible
Regulate clamp distance by holding pressing and holding part 2, and then the experiment body of different tube diameters can be clamped, therefore, aseptic behaviour
When making, by using this clamper, it is to avoid centrifuge tube contacts with glove, thus avoid centrifuge tube behaviour that is mobile and that take out
Artificial pollution occurs during work.
It should be noted that this experiment body can be various test tube, it is preferably but not limited to centrifuge tube, for satisfied clamping not
With the needs of caliber, the clamp distance between this first inner concave arc surface 400 and second inner concave arc surface 420 can be according to different tube diameters
Being adjusted/design, the centrifuge tube of 15ml, 50ml, 250ml specification is designed by the clamper preferred pin of the present embodiment.Should
The concrete structure holding part 2 does not limits, if its first end 200 and the second end 220 is oppositely arranged and the first end 200 and the second end
Distance between 220 can flexible adjustment, the technique effect of the present embodiment can be realized；Specifically, this hold part 2 it may be that but
Be not limited to spring, can deformation the elasticity of flexure plastic restored or can deformation the bending elasticity plastic that restores etc..This is years old
One inner concave arc surface 400 can be the recessed formation in inner side of the first clamping part 40, it is possible to because of the first curved setting of clamping part 40
Being formed, similarly, this second inner concave arc surface 420 can be the recessed formation in inner side of the second clamping part 42, it is possible to because of the second clamping
The curved setting in portion 42 and formed.
Further, this first clamping part 40 and second the most curved setting of clamping part 42.
Owing to this first inner concave arc surface 400 and the second inner concave arc surface 420 are because of the first clamping part 40 and the second clamping part 42
Shape and formed, it is not necessary to cambered surface, and then convenient processing are individually set in the inner side of the first clamping part 40 and the second clamping part 42, subtract
Few operation.
Further, this first clamping part 40 and the second clamping part 42 are all arranged in circular arc.
Employing circular arc is arranged, and with the tube wall shape adaptation of centrifuge tube, increases holding area, and clamping effect is more preferable, prevents
Centrifuge tube comes off.Preferably, this first clamping part 40 is identical with the caliber of 50ml centrifuge tube with the second clamping part 42
Section 1/3rd circular arcs.
Further, this first inner concave arc surface 400 and/or this second inner concave arc surface 420 are provided with anti-skid structure 402
(422)。
This anti-skid structure 402 (422) can increase the frictional force between tube wall and cambered surface, prevents centrifuge tube landing, enters one
Step enhances clamping effect.It should be noted that this anti-skid structure 402 (422) can with skid resistant course or projection, use flexible or
Elastomeric material is made, such as plastics or rubber, it is to avoid damage centrifuge tube.
Further, this anti-skid structure 402 (422) is sawtooth projection.
This sawtooth projection, while strengthening friction effect, can be increased pipe by the gap between sawtooth projection
The clamping action of wall, it is best that it grips effect.
Further, this hold part 2 include first holding part the 20, second holding part 22 and connect the first holding part 20 and
The elastic joint part 24 of the second holding part 22, this first end 200 holding part 2 is that the first holding part 20 is away from elastic joint part 24
One end, this second end 220 holding part 2 is the second holding part 22 one end away from elastic joint part 24.
This elastic joint part 24 has elasticity, and then can be with the first end 200 and second of flexible adjustment the first holding part 20
Distance between second end 220 of holding part 22, during use, user holds pressing the first holding part 20 and the second holding part
22, and shorten the distance between the first end 200 and the second end 220；When cancelling pressing, recover deformation at elastic joint part 24,
Range recovery between first end 200 and the second end 220.
It should be noted that this elastic joint part 24 directly can be connected shape by the first holding part 20 and the second holding part 22
Become, it is also possible to be a spring, V-shaped elastomer or curved elastomer etc., as long as possessing elasticity.
Further, this V-shaped setting of elastic joint part 24, wherein, the blind end of this elastic joint part 24 is away from folder
Gripping member 4 is arranged, as it is shown on figure 3, be arranged such, beneficially user holds this clamper of operation.
Further, this elastic joint part 24 is provided with reinforcement 240.
This reinforcement 240 can strengthen the intensity of elastic joint part 24, extends the service life of elastic joint part 24.
Further, this holds part 2 and holder 4 integrated injection molding is made.
Integrated injection molding technique can improve production efficiency, reduces production cost.Specifically, PVC one can be used
Injection mo(u)lding, and sterilize and pack, and single use.
Refer to the top view that Fig. 5, Fig. 5 are this utility model clamper the second embodiment.The clamping of this second embodiment
Device is with the difference of the clamper of first embodiment:
The blind end of the elastic joint part 24 in " V " is arranged near holder 4, is arranged such, and can reduce this clamper
The space taken, is conducive to storage and transport.
Refer to the top view that Fig. 6, Fig. 6 are this utility model clamper the 3rd embodiment.The clamping of this third embodiment
Device is with the difference of the clamper of first embodiment:
This curved setting of elastic joint part 24, and then elastic joint part 24 has good elasticity, convenient operation, and make
Use the life-span long.
The foregoing is only preferred embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model,
