Abstract

The utility model relates to a clip for pipet stand. In the experiment of subjects such as life science, medical science, chemistry, the volume often can use the pipette when getting reagent, and can not use same root pipette to take multiple reagent, if the experiment relates to multiple reagent, then need a fairly large number of pipette experiment, generally use the pipet stand to place the pipette. The pipet stand that uses at present easily causes the pollution of pipette, and the operation is inconvenient, still needs the problem of bimanualness. The utility model discloses a body, support arm, arm lock, shell fragment, pivot, be equipped with the pivot between the one end with dissection of body, intermediate layer, the support arm is fixed in the pivot, and the shell fragment encircles the pivot, and the shell fragment both ends are fixed on the support arm, the support arm other end and anchor clamps coupling. The utility model discloses can realize getting the one -hand operation when putting the pipette, the simple operation, but have variable damping's pivot and improved the stability of clip centre gripping pipette.

Description

A kind of clip for pipet stand

Technical field

This utility model relates to a kind of experiment auxiliary device, especially for clamping the clip of pipet on pipet stand.

Background technology

In the experiment of the subjects such as life sciences, medical science, chemistry; often use pipet when measuring reagent, and same pipet can not be used to take plurality of reagents, if experiment relates to plurality of reagents; then need a fairly large number of pipet to test, generally use pipet stand to place pipet.The structure of the pipet stand used at present such as documents below:

Patent documentation 1:CN204294290U；

Patent documentation 2:CN201959818U；

Patent documentation 3:CN204448067U；

Patent documentation 4:CN201783338U；

Patent documentation 5:CN204544239U；

Patent documentation 6:CN204122157U；

Patent documentation 7:CN203494532U；.

If document 1,4,5 is to arrange height two-ply, top plate is dug circular hole, lower plywood is dug round taper hole, during use, pipet is inserted in corresponding aperture, the bellmouth of lower plywood can hold up pipet, because pipette tip comes in contact with lower plywood, easily causes the pollution of pipet；Document 2,3 places pipet by two grooves in horizontal direction, and arranges shell fragment or the structure stability with reinforcement pipet of unrolling in groove, but its poor effect, operation inconvenience；Document 6,7 fixes pipet by clamping devices such as clips, has preferable stability, but still has the problem needing bimanualness when placing and take out pipet, and convenience is poor.

Summary of the invention

For solving the problems referred to above, this utility model devises a kind of clip for pipet stand, and described clip can automatically close and clamp, and uses and can keep open configuration after finishing, in order to reuses.Described clip assists without external force in use, can realize one-handed performance.

This utility model solution technical problem be the technical scheme is that to include body, support arm, jig arm, shell fragment, rotating shaft；One end of body is provided with interlayer, is provided with rotating shaft between interlayer, and support arm is fixed in rotating shaft, shell fragment twisted rotary shaft, and shell fragment two ends are fixed on support arm；The support arm other end connects with clamp shaft.

Further, described rotating shaft is adaptive damping rotating shaft.

Further, described shell fragment is fixed on inside the interlayer of body.

Further, described jig arm is divided into jig arm I and jig arm II two parts, and jig arm one end is flat part, and the other end is bending section.

Further, the bending section of described jig arm I and jig arm II can fasten in interdigitate mode.

Further, with one layer of rubber inside the bending section of described jig arm I and jig arm II.

The beneficial effects of the utility model are, it is possible to achieve pick and place one-handed performance during pipet, simple operation, and the rotating shaft with adaptive damping improves the stability of described clip clamping pipet.

Accompanying drawing explanation

With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.

Fig. 1 is the structural representation of this utility model embodiment；

Wherein,

1, body；2, rotating shaft；3, support arm；4, shell fragment；51, jig arm I；52, jig arm II；53, flat part；54, bending section；55, rubber layer.

Detailed description of the invention

First embodiment is arranged on pipet stand.When placing pipet, one hand is held in the middle part of pipet, makes pipet top or bottom press close to the flat part 53 of jig arm I 51 and jig arm II 52, advance to inner side simultaneously, now two support arms 3 are exerted a force by shell fragment 4, and support arm 3 will rotate centered by rotating shaft 2, drive and inwardly close up and clamp pipet.During this, because rotating shaft 2 is the rotating shaft with damping, the holding action of support arm 3 and jig arm I 51, jig arm II 52 has certain buffering, therefore does not results in the damage of pipet.It is provided with rubber layer 55 inside the bending section 54 of jig arm I 51 and jig arm II 52, can firmly clamp pipet to prevent it from gliding.

When taking out pipet, pulling out pipet, the bending section 54 of jig arm I 51 and jig arm II 52 outwards launches, and i.e. can be taken off pipet.The most again the flat part 53 of jig arm I 51 and jig arm II 52 is evened up alignment, set back, in order to next time uses.
