Novel sealing rubber plug

Abstract

The utility model provides a novel sealing rubber plug, and belongs to the technical field of rubber plugs. The sealing plug solves the problems that when a medicine bottle is sealed through an existing sealing plug in the market, the medicine bottle is sealed only through the elasticity of a rubber plug, the sealing plug is not reinforced, and therefore the using stability of the sealing plug is poor, and the sealing effect is poor. The novel sealing rubber plug comprises a rubber plug body, the inner wall of the rubber plug body is fixedly connected with a fixing plate, the top of the fixing plate is fixedly connected with a threaded rod, the top end of the threaded rod is fixedly connected with a limiting block, the threaded rod is in threaded connection with a reinforcing shell, an annular extrusion pad is arranged on the outer side of the rubber plug body, and an isolating membrane is arranged on the surface of the rubber plug body. The rubber plug has the advantages that the rubber plug body is protected and reinforced, and the sealing effect of the rubber plug body is better.

Description

Technical Field

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

[0002] When bottling medicines, rubber stoppers are commonly used to seal the bottles. However, current methods rely solely on the elasticity of the rubber stopper to achieve a seal, without reinforcing the stopper itself. This results in poor stability and ineffective sealing. Summary of the Invention

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

[0004] The purpose of this utility model can be achieved through the following technical solution: a novel sealing rubber stopper, characterized in that it includes a rubber stopper body, a fixing plate is fixedly connected to the inner wall of the rubber stopper body, a threaded rod is fixedly connected to the top of the fixing plate, a limit block is fixedly connected to the top of the threaded rod, a reinforcing shell is threadedly connected to the threaded rod, an annular compression pad is provided on the outer side of the rubber stopper body, and an isolation membrane is provided on the surface of the rubber stopper body.

[0005] In the aforementioned novel sealing rubber stopper, the main body of the rubber stopper is made of neoprene rubber.

[0006] In the aforementioned novel sealing rubber stopper, the separating membrane is a polymer inert film.

[0007] In the aforementioned novel sealing rubber stopper, the annular extrusion pad is T-shaped.

[0008] Compared with existing technologies, when this novel sealing rubber stopper is used on medicine bottles, the reinforcing shell is rotated, and the reinforcing shell contacts and squeezes the annular compression pad. In turn, the annular compression pad is squeezed, thereby squeezing the rubber stopper body located on the outside of the bottle opening, thus achieving protection and reinforcement of the rubber stopper body and making the sealing effect of the rubber stopper body better.

[0010] Figure 2 This is a cross-sectional schematic diagram of the novel sealing rubber plug.

[0011] In the diagram, 1 is the rubber stopper body; 2 is the fixing plate; 3 is the threaded rod; 4 is the reinforced shell; 5 is the annular extrusion pad; 6 is the limiting block; and 7 is the isolation membrane. Detailed Implementation

[0012] 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.

[0013] like Figure 1 , 2 As shown, this novel sealing rubber stopper is characterized by comprising a rubber stopper body 1, a fixing plate 2 fixedly connected to the inner wall of the rubber stopper body 1, a threaded rod 3 fixedly connected to the top of the fixing plate 2, a limit block 6 fixedly connected to the top of the threaded rod 3, a reinforcing shell 4 threadedly connected to the threaded rod 3, an annular compression pad 5 provided on the outer side of the rubber stopper body 1, and an isolation membrane 7 provided on the surface of the rubber stopper body 1. After the rubber stopper body 1 is installed on the medicine bottle, the reinforcing shell 4 is rotated and moves along the threaded rod 3, so that the reinforcing shell 4 gradually fits against the outer side of the annular compression pad 5 and squeezes the annular compression pad 5. At the same time, the annular compression pad 5 will squeeze the rubber stopper body 1 located outside the bottle mouth, so that the rubber stopper body 1 outside the bottle mouth can fit more tightly against the bottle mouth, making the sealing effect of the rubber stopper body 1 better.

[0014] Preferably, the rubber stopper body 1 is made of neoprene rubber, which has good aging resistance and improves the service life of the rubber stopper body 1.

[0015] Preferably, the separator 7 is a polymer inert film, which can prevent the medicine in the medicine bottle from coming into contact with the rubber stopper body 1 and causing contamination to the rubber stopper body 1.

[0016] Preferably, the annular extrusion pad 5 is T-shaped.

[0017] 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.

[0018] Although this document frequently uses terms such as rubber stopper body 1, fixing plate 2, threaded rod 3, reinforced shell 4, annular compression pad 5, limiting block 6, and separating membrane 7, 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 utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
