Abstract
The utility model relates to a beaker cap, wherein a circular hole a (2) is formed on a flat-top cup cap (1), a rubber sheet (3) is arranged at the circular hole a (2), covers the whole circular hole a (2) in a sealing manner and is fixed on the flat-top cup cap (2), a circular hole b (4) is formed on the rubber sheet (3), a rugged edge (5) is arranged at the edge of the lower surface of the flat-top cup cap (1), and the size of the flat-top cup cap (1) is fitted with the size of a beaker opening. The beaker cap disclosed by the utility model can be used for carrying out stirring and temperature measurement under a sealed beaker environment.
Description
Technical field
The utility model relates to a kind of beaker lid.
Background technology
At present, using beaker generally all is uncovered operation, when the reactant in the beaker reacts; Unsafe situation appears easily, when beaker lid is provided to beaker, and can be when reactant reacts in the beaker; The environment of a sealing is provided; But some reactant need react under the operation of stirring, and so just can't a sealed environment be provided for the reactant that need stir, and can't carry out thermometric to the beaker environment of sealing.
Summary of the invention
The utility model is to above-mentioned technical problem, and technical problem to be solved is a kind of beaker lid that can stir the beaker environment of sealing with thermometric of design.
A kind of beaker Gai Eryan with regard to the utility model design; On the flat-top bowl cover, have circular hole a, at circular hole a place sheet rubber is installed, sealing covers whole circular hole a; And fix with the flat-top bowl cover; On sheet rubber, have circular hole b, be provided with the friction limit in the edge of flat-top bowl cover lower surface, the specification of the size of flat-top bowl cover and beaker mouth adapts.
Said sheet rubber is to fix with the inward flange of circular hole a and near the upper and lower surfaces of the flat-top bowl cover at circular hole a edge.
The diameter of said circular hole b is 1mm-2mm, and the diameter of said circular hole a is greater than the diameter of circular hole b.
Designed a kind of can the stirring the beaker environment of sealing and the beaker of thermometric lid with regard to the utility model; Because the diameter of circular hole b is merely 1mm-2mm, and circular hole b is elastomeric material, has shrinkage and elasticity; Can from circular hole b, insert stirring rod or thermometer; And circular hole b closely contacts with stirring rod or thermometer, forms good sealing in the contact position, and sheet rubber sealing covers circular hole a and is provided with the friction limit in the edge of flat-top bowl cover lower surface in addition; Have good sealing effectiveness with beaker, so just realized the beaker environment of sealing is stirred the operation with thermometric.
Figure of description
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the specific embodiment a of the utility model.
Fig. 3 is the specific embodiment b of the utility model.
Wherein, 1. flat-top bowl cover, 2. circular hole a, 3. sheet rubber, 4. circular hole b, 5. friction limit, 6. stirring rod, 7. thermometer.
The specific embodiment
Below in conjunction with Figure of description the specific embodiment of the utility model is done further detailed explanation.
In the accompanying drawing 1; On flat-top bowl cover 1, have circular hole a, at circular hole a place sheet rubber 3 is installed, sealing covers whole circular hole a; And it is fixing with flat-top bowl cover 1; On sheet rubber 3, have circular hole b, be provided with friction limit 5 in the edge of flat-top bowl cover 1 lower surface, the specification of the size of flat-top bowl cover 1 and beaker mouth adapts.
Said sheet rubber 3 is to fix with the inward flange of circular hole a and near the upper and lower surfaces of the flat-top bowl cover 1 at circular hole a edge.
The diameter of said circular hole b is 1mm-2mm, and the diameter of said circular hole a is greater than the diameter of circular hole b.
This beaker lid can specifically be used in beaker environment to sealing and stir the operation with thermometric, and shown in Fig. 2, the related beaker lid of this utility model is used in combination with stirring rod 6, accomplishes the operation that the beaker environment that seals is stirred.Stirring rod 6 is inserted from circular hole b; And circular hole b closely contacts with stirring rod 6; Form good sealing in the contact position; Sheet rubber 3 sealing covers circular hole a and is provided with friction limit 5 in the edge of flat-top bowl cover 1 lower surface in addition, has good sealing effectiveness with beaker, has so just realized the operation that the beaker environment that seals is stirred.
Shown in Fig. 3, the related beaker lid of this utility model is used in combination with thermometer 7, accomplishes the operation that the beaker environment that seals is stirred.Thermometer 7 inserts from circular hole b; And circular hole b closely contacts with thermometer 7; Form good sealing in the contact position; Sheet rubber 3 sealing covers circular hole a and is provided with friction limit 5 in the edge of flat-top bowl cover 1 lower surface in addition, has good sealing effectiveness with beaker, has so just realized the beaker environment that seals is carried out the operation of thermometric.
Combine accompanying drawing that the embodiment of the utility model has been done detailed description above; But the utility model is not limited to above-mentioned embodiment; In the ken that those of ordinary skills possessed, can also under the prerequisite that does not break away from the utility model aim, make various variations.
