Description

Technical Field

[0001] The utility model relates to the technical field of rubber plugs, in particular to a rubber plug for a syringe which is convenient to draw out. Background Art

[0002] As we all know, rubber stoppers for syringes usually refer to syringe accessories used in medical or laboratory applications. Rubber stoppers are usually made of medical grade rubber or silicone to ensure compatibility with drugs or chemicals while maintaining their sealing properties. These rubber stoppers can ensure that the drug will not leak when the syringe is used, and can keep the internal environment clean and sterile. Due to the air squeeze during the push, the push rod is pulled out after the push is completed, which is particularly laborious. Utility Model Content

[0003] 1. Technical issues to be solved

[0004] In view of the deficiencies in the prior art, the utility model provides a rubber stopper for a syringe which is easy to draw out.

[0005] (II) Technical solution

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a rubber plug for a syringe that is easy to pull out, comprising a rubber plug body, wherein the upper end of the rubber plug body is provided with a plurality of grooves and protrusions, an elastic block is provided inside the groove, a card slot is provided inside the elastic block, a docking block is provided at the lower end of the protrusion that is inserted into the card slot, and the bottom end of the protrusion contacts the rubber plug body.

[0007] Furthermore, the present invention is improved in that the number of the grooves and the number of the protrusions are both 6.

[0008] Furthermore, the present invention is improved in that the protrusion is a spherical structure, and the groove, the docking block and the elastic block are all cylindrical structures.

[0009] Furthermore, the present invention is improved in that the bottom end of the docking block is bonded to the inside of the card slot.

[0010] Furthermore, the present invention has been improved in that the protruding block and the docking block are both made of rubber.

[0011] Furthermore, the present invention is improved in that the protruding block and the docking block are an integrated structure.

[0012] (III) Beneficial effects

[0013] Compared with the prior art, the utility model provides a conveniently withdrawn rubber plug for a syringe, which has the following beneficial effects:

[0014] The conveniently-pulled rubber plug for syringes can support the convex block by means of the elastic block and the docking block when the rubber plug body is in use, so that the convex block can contact the top of the needle tube. At this time, the top of the rubber plug body will not fit the top of the needle tube, so that the rubber plug body can be pulled out with less effort.

[0015] When the plug body is pushed, the liquid in the syringe can be injected. As the plug body moves, the protrusion can contact the top of the syringe. Continuing to apply force can compress the elastic block. At this time, the protrusion will also be slightly compressed, so that the protrusion can be completely inside the groove, and the liquid in the syringe can be injected more thoroughly.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 The utility model discloses a conveniently-pulled rubber plug for a syringe, comprising a rubber plug body 1, wherein a plurality of grooves 2 and a convex block 3 are arranged at the upper end of the rubber plug body 1, wherein an elastic block 5 is arranged inside the groove 2, wherein a card slot 6 is arranged inside the elastic block 5, and a docking block 4 is arranged at the lower end of the convex block 3 to be inserted into the card slot 6, wherein the bottom end of the convex block 3 contacts the rubber plug body 1. In this structure, before the rubber plug body 1 is used, the convex block 3 can be supported by the elastic block 5 and the docking block 4, so that the convex block 3 can contact the top end of the needle tube, and the top end of the rubber plug body 1 will not fit with the top end of the needle tube, so that the rubber plug body 1 can be pulled out with more effort.

[0022] When the plug body 1 is pushed, the liquid in the syringe can be injected. As the plug body 1 moves, the protrusion 3 can contact the top of the syringe. Continuing to apply force can compress the elastic block 5. At this time, the protrusion 3 will also be slightly compressed, so that the protrusion 3 can be completely inside the groove 2, so that the liquid in the syringe can be injected more thoroughly.

[0023] Furthermore, the number of the grooves 2 and the number of the protrusions 3 can be 6.

[0024] In this structure, the protrusion 3 can be a spherical structure, and the groove 2, the docking block 4 and the elastic block 5 can be a cylindrical structure.

[0025] Furthermore, the bottom end of the docking block 4 is bonded to the inside of the slot 6, which can facilitate the assembly of the protrusion 3. The protrusion 3 and the docking block 4 are both made of rubber, and the protrusion 3 and the docking block 4 are an integrated structure.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
