Abstract
The utility model discloses a stopper for injection, which comprises a stopper body made of a rubber material, a hole formed in the stopper body, and a blocking surface fixedly arranged at one end part of the stopper body and used for sealing the hole, wherein a center line of the hole is coincided with a center line of the stopper body; and a self-closed elastic opening communicated with the hole is formed in the blocking surface. As the elastic opening is formed in the blocking surface, a needle passes through the elastic opening to enter the hole when the injection is required, the needle is pulled out after use completion, then the elastic opening automatically recovers under the action of an elastic force of the elastic opening, and the operation and use are relatively convenient.
Description
Technical field
The utility model relates to a kind of injection stopper.
Background technique
Injection stopper of the prior art, comprise the plug body made by rubber material, be opened in perforate on the described plug body, be fixedly installed on described plug body an end be used for sealing the shutoff face of described perforate, during injection, need to shutoff face be exposed by syringe end, yet when with syringe end shutoff face being exposed, dynamics is difficult the control, dynamics hour, shutoff face is difficult for being pierced, when dynamics is larger, to fill in easily body and extrude, use inconvenient.
The model utility content
The purpose of this utility model is to overcome the defective that exists in the prior art, and a kind of injection stopper is provided, and by at shutoff face elastic opening being set, injection is used more convenient.
For achieving the above object, the technical solution of the utility model has provided a kind of injection stopper, comprise the plug body made by rubber material, be opened in perforate on the described plug body, be fixedly installed on described plug body an end be used for sealing the shutoff face of described perforate, the center line of the center line of described perforate and described plug body coincides, and offers elastic opening that be connected with described perforate and can auto-closing on the described shutoff face.
As preferably, described elastic opening is cross.
As preferably, described plug body comprise front end, with the rearward end that described front end is fixedly connected, described shutoff face is arranged on the described front end.
As preferably, stepped cylindrical of described front end.
As preferably, stepped cylindrical of described rearward end.
Advantage of the present utility model and beneficial effect are: by at shutoff face elastic opening being set, when needing injection to use, syringe end is passed elastic opening and is entered in the perforate, finish using syringe end extracted after, elastic opening is under the effect of self elastic force, automatically recover, operation is used all more convenient.
Description of drawings
Fig. 1 is the utility model plan view;
Fig. 2 is left view of the present utility model;
Fig. 3 is right elevation of the present utility model.
Among the figure: 1, perforate; 2, shutoff face; 3, elastic opening; 4, front end; 5, rearward end.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1-Figure 3, a kind of injection stopper, comprise the plug body made by rubber material, be opened in perforate 1 on the described plug body, be fixedly installed on described plug body an end be used for sealing the shutoff face 2 of described perforate 1, the center line of the center line of described perforate 1 and described plug body coincides, and offers elastic opening 3 that be connected with described perforate 1 and can auto-closing on the described shutoff face 2.Described shutoff face 2 is very thin one deck sheet rubber, and described plug body, shutoff face 2 are one-body molded.
As shown in Figure 2, described elastic opening 3 is cross.Without diagram, described elastic opening 3 can also be in-line, Mi-shape etc.
As shown in Figure 1, the rearward end 5 that described plug body comprises front end 4, is fixedly connected with described front end 4, described shutoff face 2 is arranged on the described front end 4.Stepped cylindrical of described front end 4.Have circular arc chamfering on the described front end 4, stepped cylindrical of described rearward end 5 also has circular arc chamfering on the described rearward end 5.The size of described front end 4 is less than the size of described rearward end 5.
During use, directly syringe end is passed elastic opening 3 and enter in the perforate 1, after finishing using, syringe end is extracted, elastic opening 3 is closed under the effect of the elastic force of self.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
