Abstract
The utility model provides a novel halogenated butyl rubber plug with strong sealing performance for fat emulsion for injection, which comprises a plug body and a press plug, wherein the top of the plug body is provided with an annular groove, the press plug is clamped with the groove, and the thickness of the press plug is larger than the width of the groove; the groove wall is covered with a spring plate. The utility model discloses a theory of operation does: firstly, the plug body is arranged in a bottle mouth, a gap is arranged between the plug body and the bottle mouth, then the press plug is inserted into the groove, and the groove is extruded because the thickness of the press plug is larger than the width of the groove, so that the plug body deforms, the plug body is tightly attached to the bottle mouth, and the sealing connection of the plug body and the bottle mouth is realized; because the press plug and the elastic sheet are made of metal, the friction force between the press plug and the elastic sheet is small, the press plug can be easily inserted into the groove, and the problem that the rubber plug is difficult to install is solved.
Description
Technical Field
The utility model relates to a plug field specifically is a novel halogenated butyl rubber buffer of strong leakproofness is used to fat emulsion for injection.
Background
The butyl rubber plug for encapsulating the solvent medicine bottle has very wide application in the field of medicine. The common rubber plug consists of a plug crown and a plug neck, and the plug neck is in direct contact with the inner wall of the bottle mouth of the solvent bottle for sealing. Because the plug neck is in interference fit with the inner wall of the bottle mouth, the plug neck is also provided with a certain length, and the installation is laborious.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: the technical problem that the traditional rubber plug is difficult to install is solved.
The utility model provides a novel halogenated butyl rubber plug with strong sealing performance for fat emulsion for injection, which comprises a plug body and a press plug, wherein the top of the plug body is provided with an annular groove, the press plug is clamped with the groove, and the thickness of the press plug is larger than the width of the groove; the groove wall is covered with a spring plate.
The utility model discloses a theory of operation does: firstly, the plug body is arranged in a bottle mouth, a gap is arranged between the plug body and the bottle mouth, then the press plug is inserted into the groove, and the groove is extruded because the thickness of the press plug is larger than the width of the groove, so that the plug body deforms, the plug body is tightly attached to the bottle mouth, and the sealing connection of the plug body and the bottle mouth is realized; because the press plug and the elastic sheet are made of metal, the friction force between the press plug and the elastic sheet is small, the press plug can be easily inserted into the groove, and the problem that the rubber plug is difficult to install is solved.
Furthermore, the lower end of the press plug is provided with a latch, and the bottom of the elastic sheet is provided with a bayonet which is clamped with the latch. Through latch and bayonet joint, realize the fixed mounting of tamponade, avoid tamponade to break away from the cock body.
Further, the bottom of the plug body is provided with a notch. The arrangement of the notch reduces the thickness of the rubber plug at the insertion position of the injector, and the injector can conveniently penetrate through the rubber plug.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a cross-sectional view of the present invention;
in the figure: 1. a plug body; 2. pressing and plugging; 3. a spring plate; 11. a groove; 12. a recess; 21. clamping teeth; 31. and (4) a bayonet.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1, the utility model relates to a novel halogenated butyl rubber plug with strong sealing performance for fat emulsion for injection, which comprises a plug body 1 and a press plug 2, wherein the top of the plug body 1 is provided with an annular groove 11, the press plug 2 is clamped with the groove 11, and the thickness of the press plug 2 is larger than the width of the groove 11; the groove wall of the groove 11 is covered with an elastic sheet 3; the lower end of the press plug 2 is provided with a latch 21, the bottom of the elastic sheet 3 is provided with a bayonet 31 clamped with the latch 21, the press plug 2 is fixedly installed by clamping the latch 21 with the bayonet 31, and the press plug 2 is prevented from being separated from the plug body 1;
the bottom of the plug body 1 is provided with a notch 12, and the arrangement of the notch 12 reduces the thickness of a rubber plug at the insertion position of the injector, so that the injector can conveniently penetrate through the rubber plug;
the utility model discloses a theory of operation does: firstly, the plug body 1 is arranged in a bottle mouth, a gap is arranged between the plug body 1 and the bottle mouth, then the press plug 2 is inserted into the groove 11, and the groove 11 is extruded because the thickness of the press plug 2 is larger than the width of the groove 11, so that the plug body 1 deforms, the plug body 1 is tightly attached to the bottle mouth, and the sealing connection of the plug body 1 and the bottle mouth is realized; because the press plug 2 and the elastic sheet 3 are made of metal, the friction force between the press plug 2 and the elastic sheet 3 is small, the press plug 2 can be easily inserted into the groove 11, and the problem that the rubber plug is difficult to install is solved.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
