Abstract
The utility model belongs to the field of chemical apparatus and equipment, in particular to a suction flask connector. The connector comprises a rubber stopper (1). A through hole (2) is arranged between the upper and lower bottom faces of the rubber stopper (1). A rubber sleeve (3) is arranged at the top of the rubber stopper (1). The rubber sleeve (3) is big at the top but small at the bottom. The inner diameter at the bottom of the rubber sleeve (3) is equal to the aperture of the through hole (2). The wall thickness of the rubber stopper (1) is 0.5-1cm. The rubber stopper (1) is big at the top but small at the bottom. The suction flask connector provided by the utility model has the advantages of simple structure and convenience in use, and sealed connection between a sand core crucible and the suction flask can be realized easily.
Description
Technical field
The utility model belongs to the chemical apparatuses apparatus field, particularly a kind of bottle,suction connector.
Background technology
Suction filtration is a kind of common experimental implementation, is mainly used in Separation of Solid and Liquid.The suction filtration device generally comprises bottle,suction and Buchner funnel.Be with the rubber stopper of perforate on the handle of Buchner funnel,, can guarantee the sealing between Buchner funnel and the bottle,suction the bottleneck of rubber stopper plug to bottle,suction.In the analytical chemistry test, core crucible also commonly used cooperates with bottle,suction realizes Separation of Solid and Liquid.But core crucible volume is less, and is mainly processed by glass material, how to realize that being tightly connected of core crucible and bottle,suction is a difficult problem.The bottleneck that one section bicycle tube inserts bottle,suction is generally cut in the laboratory, inserts the inner tube of a tyre to the core crucible again, and bicycle tube plays the effect that is tightly connected between the outer wall of the bottleneck of bottle,suction and core crucible.The weak point of this solution is: 1. the internal diameter of the bottleneck of the caliber of bicycle tube and bottle,suction does not match, and thin, the poor plasticity of the inner tube of a tyre is difficult to accomplish the sealing between the inner tube of a tyre and the bottle,suction bottleneck in addition; 2. the core crucible is mainly processed by glass material, can not exert oneself toward the bottle,suction bottle plug, and the core crucible not only is difficult to be fixed on the bottle,suction bottleneck, and broken easily.
The utility model content
The purpose of the utility model is the deficiency that overcomes prior art, and a kind of bottle,suction connector is provided, and this connector can easily be realized being tightly connected of core crucible and bottle,suction.
The scheme that the utility model solve the technical problem is: a kind of bottle,suction connector; It comprises rubber stopper, between the last bottom surface of rubber stopper through hole is set, and the top of rubber stopper is provided with rubber sleeve; The rubber sleeve top is big, the bottom is little, and the internal diameter of rubber sleeve bottom equates with the aperture of through hole.
During use, rubber stopper is filled in the bottle,suction bottleneck, guarantee being tightly connected of connector and bottle,suction bottleneck; The rubber sleeve top is big, the bottom is little; The internal diameter of rubber sleeve bottom equates that with the aperture of through hole rubber stopper turns under the rubber sleeve after filling in the bottle,suction bottleneck, lets the bottom of core crucible prop up the through hole of rubber stopper; With turning on the rubber sleeve, rubber sleeve is enclosed within on the outer wall of core crucible again.Like this, can realize being tightly connected between core crucible and the bottle,suction.
As further technical scheme, the wall thickness of said rubber stopper is 0.5～1 centimetre.
The wall thickness of rubber stopper is 0.5～1 centimetre, can guarantee the sealing effectiveness of rubber stopper, makes rubber stopper comparatively soft again, conveniently rubber stopper is filled in or is extracted from the bottle,suction bottleneck smoothly.
As further technical scheme, said rubber stopper top is big, the bottom is little.
The rubber stopper top is big, the bottom is little, further just with rubber stopper fills in or extracts from the bottle,suction bottleneck smoothly.
The utlity model has advantage simple in structure, easy to use, can easily realize being tightly connected of core crucible and bottle,suction.
Description of drawings
Fig. 1 is the cutaway view of the utility model, and rubber sleeve is the down turning shape attitude among the figure;
Fig. 2 is the structural representation of the utility model, and rubber sleeve is presented the state of turning among the figure;
Fig. 3 is the utility model with after bottle,suction is connected, the state diagram when the core crucible is put on connector;
The state diagram of Fig. 4 after to be the utility model bottle,suction and core crucible be tightly connected.
The specific embodiment
Like Fig. 1, shown in Figure 2, a kind of bottle,suction connector comprises rubber stopper 1; Rubber stopper 1 top is big, the bottom is little; Between the last bottom surface of rubber stopper 1 through hole 2 is set, the wall thickness of rubber stopper 1 is 0.5～1 centimetre, and the top of rubber stopper 1 is provided with rubber sleeve 3; Rubber sleeve 3 tops are big, the bottom is little, and the internal diameter of rubber sleeve 3 bottoms equates with the aperture of through hole 2.
The method for using of this connector is: as shown in Figure 3; Rubber stopper 1 is filled in the bottleneck of bottle,suction 4; Turn down rubber sleeve 3, let rubber sleeve 3 be enclosed within on the outer wall of bottle,suction 4 bottlenecks, prop up the bottom of core crucible 5 at through hole 2 places of rubber stopper 1; With turning on the rubber sleeve 3, rubber sleeve 3 is enclosed within on the outer wall of core crucible 5 again.Like this, can realize being tightly connected between core crucible 5 and the bottle,suction 4, the state after being tightly connected is as shown in Figure 4.
Claims (3)
1. bottle,suction connector; It is characterized in that: it comprises rubber stopper (1); Through hole (2) is set between the last bottom surface of rubber stopper (1); The top of rubber stopper (1) is provided with rubber sleeve (3), and rubber sleeve (3) top is big, the bottom is little, and the internal diameter of rubber sleeve (3) bottom equates with the aperture of through hole (2).
2. a kind of bottle,suction connector as claimed in claim 1 is characterized in that: the wall thickness of said rubber stopper (1) is 0.5～1 centimetre.
3. according to claim 1 or claim 2 a kind of bottle,suction connector, it is characterized in that: said rubber stopper (1) top is big, the bottom is little.
