Description

Technical Field

[0001] This utility model belongs to the field of rubber stopper technology, and relates to a rubber stopper, particularly a high-stability rubber stopper. Background Technology

[0002] Most existing bottled medicine bottles use rubber stoppers for sealing. When sealing a medicine bottle, the rubber stopper is usually squeezed by the mouth of the bottle to achieve a tight seal between the rubber stopper and the inside of the mouth. However, when it is necessary to remove the rubber stopper, due to the characteristics of the rubber stopper, it is difficult to reduce the squeezing force exerted by the rubber stopper on the mouth of the bottle. This makes it extremely difficult to remove the tightly sealed rubber stopper, which cannot meet the usage requirements. Therefore, designing a highly stable rubber stopper is of great significance. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a highly stable rubber stopper.

[0004] The objective of this utility model can be achieved through the following technical solution: A high-stability rubber stopper, characterized in that it includes a rubber stopper body, a circular groove is formed inside the rubber stopper body, a threaded sleeve communicating with the circular groove is fixedly arranged inside the rubber stopper body, a threaded rod is threadedly connected inside the threaded sleeve, a circular plate is fixedly arranged at the bottom end of the threaded rod and the circular plate is located inside the circular groove, a pressing part is arranged on the outside of the circular plate and the pressing part squeezes the inside of the circular groove, and an adjusting plate is fixedly arranged at the top of the threaded rod.

[0005] In the aforementioned high-stability rubber stopper, the main body of the rubber stopper is made of halogenated butyl material.

[0006] In the aforementioned high-stability rubber stopper, the pressure-retaining portion is arranged in a semi-circular shape.

[0007] Compared with existing technologies, this high-stability rubber stopper reduces the squeezing force exerted by the rubber stopper on the mouth of the medicine bottle when disassembling the rubber stopper, making the disassembly of the rubber stopper easier and more convenient. Attached Figure Description

[0008] Figure 1 This is a three-dimensional schematic diagram of a highly stable rubber stopper.

[0009] Figure 2 This is a cross-sectional structural diagram of the highly stable rubber stopper.

[0010] In the diagram, 1 is the rubber stopper body; 2 is the circular groove; 3 is the threaded sleeve; 4 is the threaded rod; 5 is the circular plate; 6 is the pressing part; and 7 is the adjusting plate. Detailed Implementation

[0011] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0012] like Figure 1-2 As shown, this high-stability rubber stopper includes a rubber stopper body 1. A circular groove 2 is formed inside the rubber stopper body 1. A threaded sleeve 3, communicating with the circular groove 2, is fixedly installed inside the rubber stopper body 1. A threaded rod 4 is threadedly connected inside the threaded sleeve 3. A circular plate 5 is fixedly installed at the bottom end of the threaded rod 4, and the circular plate 5 is located inside the circular groove 2. A pressing part 6 is provided on the outer side of the circular plate 5, and the pressing part 6 exerts pressure on the inner side of the circular groove 2. An adjusting plate 7 is fixedly installed at the top of the threaded rod 4. When in use, the surface of the rubber stopper body 1 is in contact with the inner side of the bottle mouth. At this time, the rubber stopper body 1 is not squeezed by the bottle mouth. Then, by holding the rubber stopper body 1 still and rotating the adjusting plate 7, the threaded rod 4 and the threaded rod 4 are engaged. With the cooperation of the sleeve 3, the circular plate 5 is moved to the lower part of the circular groove 2. When the circular plate 5 moves to the lower part of the circular groove 2, the pressing part 6 of the circular plate 5 squeezes the rubber stopper body 1, so that the rubber stopper body 1 makes close contact with the inside of the medicine bottle mouth, thereby achieving a tight seal. When it is necessary to disassemble the rubber stopper body 1, the adjusting plate 7 is rotated to move the circular plate 5 to the upper part of the circular groove 2. When the circular plate 5 moves to the upper part of the circular groove 2, the position of the circular plate 5 exceeds the position where the rubber stopper body 1 contacts the medicine bottle mouth. At this time, the rubber stopper body 1 no longer makes close contact with the inside of the medicine bottle mouth, and the operator can easily disassemble the rubber stopper body 1, improving the convenience of using the rubber stopper body 1.

[0013] Preferably, the rubber stopper body 1 is made of halogenated butyl material, which can withstand the erosion of corrosive substances such as strong acids and strong alkalis in the medicine, maintain long-term sealing performance, and has high storage stability.

[0014] Preferably, the pressing part 6 is semi-circular. When the circular plate 5 moves in the circular groove 2, the semi-circular shape can reduce the moving resistance of the circular plate 5 and make it easier for the circular plate 5 to move.

[0015] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0016] Although this document uses a number of technical terms, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.
