Embodiment

The technical solution of the utility model is clearly and completely described below in conjunction with accompanying drawing, it is clear that described Embodiment is the utility model part of the embodiment, rather than whole embodiments.Based on the embodiment in the utility model, sheet The every other embodiment that field those of ordinary skill is obtained under the premise of creative work is not made, belongs to this practicality Novel protected scope.

Fig. 1 to Fig. 2 shows a kind of volumetric flask bottle stopper attachment means embodiment provided by the utility model.The present embodiment pair Answer the volumetric flask and bottle stopper design shown in Fig. 3 and Fig. 4.

From figure 1 it appears that the volumetric flask bottle stopper attachment means include the first attachment structure 1 and the second attachment structure 2. First attachment structure, 1 corresponding volumetric flask bottleneck design, the corresponding bottle stopper design of the second attachment structure 2.Due to bottle stopper and volumetric flask phase Coordinate, the first attachment structure 1 and the second attachment structure 2 are essentially identical.Fig. 2 is refer to, the first attachment structure 1 includes the first connection Ring 11.First connection ring 11 is circular ring, is detachably sheathed on volumetric flask bottleneck periphery.The one end of first connection ring 11 has There is the first elastic bayonet lock 12, the other end is inlaid with the first magnet 13.Volumetric flask Bottle neck keeper is easy in the setting of first elastic bayonet lock 12 Enter in the first connection ring 11.

Second attachment structure 2 includes the second connection ring.Second connection ring is circular ring, is detachably sheathed on outside bottle stopper Week.The second connection ring one end has the second elastic bayonet lock, and the other end is inlaid with and 13 opposite polarity second magnetic of the first magnet Iron.The setting of second elastic bayonet lock is easy to volumetric flask bottle stopper to be caught in the second connection ring.It should be evident that available can be by the first magnetic Property absorption metal structure replace the second magnet.

The material of first connection ring 11 and the second connection ring is plastics that have certain toughness and hardness, ageing-resistant.

As another embodiment, slot is provided with the first connection ring 11, is provided with and blocks in the second connection ring Close the snap fit tabs that groove coordinates.First attachment structure 1 and the second attachment structure 2 are realized by the cooperation of slot and snap fit tabs Both is detachably connected.

Corresponded for the ease of differentiation and volumetric flask with bottle stopper, the first attachment structure 1 and second attachment structure 2 are set It is equipped with unique corresponding mark structure.The mark structure can be unique corresponding raised and groove.

As another embodiment, the first connection ring 11 and the second connection ring can be only circular ring structure, be not provided with elasticity Bayonet socket, the first connection ring 11 are detachably connected with bottleneck and the second connection ring with bottle stopper by being interference fitted realization.

As another embodiment, the first attachment structure 1 and the second attachment structure 2 are structure as a whole.

It should be noted that the first attachment structure 1 and the second attachment structure 2 are fixed structure made of hard material, this Fixed structure made of place's hard material is i.e. the first attachment structure 1 and the second connection knot for cotton rope compared with the prior art Position between structure 2 is fixed, to own material type without considered critical.

Obviously, above-described embodiment is only intended to clearly illustrate example, and is not the restriction to embodiment.It is right For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of change or Change.There is no necessity and possibility to exhaust all the enbodiments.And the obvious change thus extended out or Among the protection domain that variation is created still in the utility model.
