Abstract
The utility model provides an experimental bottle plug. According to the technical scheme, the experimental bottle plug comprises a plug body, a nut and a stirring shaft, wherein a central hole is formed inside the plug body; an internal thread hole is formed in the nut; the stirring shaft penetrates through the central hole of the plug body and the internal thread hole of the nut; clearances between the stirring shaft and the central hole of the plug body and between the stirring shaft and the internal thread hole of the nut are wound by asbestos wires; the asbestos wires are screwed and fixed through the internal thread hole of the nut. The aim of stirring under the condition of sealing can be achieved. According to the scheme, the plug body consists of four circular truncated cones of different shapes, and an included angle between the side wall of the third circular truncated cone and a horizontal plane is greater than an included angle between the side wall of the fourth circular truncated cone and the horizontal plane. By virtue of only one plug body, three-stage sealing can be realized, and the sealing effect of the plug body is further ensured.

Summary of the invention
Technical problem to be solved in the utility model, is exactly for the existing deficiency of prior art, and the experiment bottle stopper that a kind of not only good sealing effect is provided and can stirs under air-proof condition.
This programme is achieved by the following technical measures: experiment bottle stopper of the present utility model, comprise cock body, nut and shaft, described cock body inside is provided with centre hole, on nut, be provided with internal thread hole, shaft runs through the centre hole of cock body and the internal thread hole of nut, space between space between described shaft and cock body centre hole, shaft and nut internal thread hole is all wound with asbestos yarn, and this asbestos yarn is tightened by the internal thread hole of nut.Centre hole is set on cock body shaft can be installed easily, to realize agitating function.Space between shaft and centre hole and internal thread hole is wound around upper asbestos yarn, is used for guaranteeing sealing effectiveness between shaft and cock body.
Further improvement of the utility model is: described cock body consists of four sections of difform round platforms, first paragraph round platform is/the trapezoidal round platform of shape, the trapezoidal round platform of the 3rd section of round platform and the 4th section of round platform Wei/shape, the second segment round platform between first paragraph round platform and the 3rd section of round platform is arc round platform.Four sections of difformity round platform designs of cock body, except first paragraph round platform, other each round platforms are respectively primary seals, a cock body just can be realized three grades of sealings, has further guaranteed the sealing effectiveness of cock body.
Further improvement of the utility model is: the angle between first paragraph round platform sidewall and horizontal surface is γ, 90 ° of 85 ° of < γ <.
Further improvement of the utility model is: the angle between the 3rd section of round platform sidewall and horizontal surface is β, 110 ° of 105 ° of < β <.
Further improvement of the utility model is: the angle between the 4th section of round platform sidewall and horizontal surface is α, 100 ° of 90 ° of < α <.Angle between the 3rd section of round platform sidewall and horizontal surface is greater than the angle between the 4th section of round platform sidewall and horizontal surface, and this kind is designed with and is beneficial to the leak tightness that guarantees cock body.
Further improvement of the utility model is: described cock body is the cock body that soft-plastic material is made.The flexible ability of soft-plastic material is strong, good sealing effect.
Further improvement of the utility model is: described cock body is the cock body that vegetable cork is made.The flexible ability of vegetable cork can either meet the seal request while testing, and is conducive to again the location of shaft, and sealing and the mixing effect of the cock body made from vegetable cork are ideal.
The beneficial effect of this programme can be learnt according to the narration to such scheme, because shaft in this scheme runs through the centre hole of cock body and the internal thread hole of nut, and the space between the space between shaft and cock body centre hole, shaft and nut internal thread hole is all wound with asbestos yarn, can realize the object stirring under air-proof condition; The cock body of this programme consists of four sections of difform round platforms, and the angle between the 3rd section of round platform sidewall and horizontal surface is greater than the angle between the 4th section of round platform sidewall and horizontal surface, and a cock body just can be realized three grades of sealings, has further guaranteed the sealing effectiveness of cock body.As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.
