Abstract
The utility model relates to a stable syringe. The stable syringe comprises a needle cylinder and a needle rod matched with the needle cylinder, wherein a rubber piston matched with the inner wall of the needle cylinder is arranged at the front end of the needle rod; a needle bed for being connected with a needle head is arranged at the front end of the needle cylinder; a needle bed jacket is arranged at the front end of the needle cylinder; the needle bed is positioned in the needle bed jacket; a groove for accommodating the needle head is formed by an outer ring surface of the needle bed and an inner ring of the needle bed jacket; and threads are formed on an inner ring surface of the needle bed jacket. The needle bed jacket is arranged on an outer ring of the needle bed, so that a connecting end of the needle head is limited between a line needle bed and the needle bed jacket, so that the needle head is not likely to shake leftwards and rightwards and the stability of the needle head is improved.
Description
Technical field
This utility model relates to a kind of steady type syringe.
Background technology
Syringe is a kind of thing commonly used in hospital; mainly syringe and shank form again; be provided with needle stand for connecting needle at the front end of syringe; traditional syringe front end just only arranges a needle stand; lack the protection to syringe needle, the phenomenon that drops appears in syringe needle easily after the double swerve on needle stand.
The utility model content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of steady type syringe is provided, solve traditional syringe needle and rock easily the defective that drops at last on needle stand.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of steady type syringe, comprise syringe and the shank that matches with syringe, described shank front end is provided with the rubber piston suitable with the syringe inwall, described syringe front end is provided with the needle stand for connecting needle, described syringe front end also is provided with the needle stand sheath, described needle stand is positioned at the needle stand sheath, and the outer ring face of needle stand and the inner ring of needle stand sheath are formed for placing the groove of syringe needle.
Further, the inner ring face of described needle stand sheath is provided with screw thread.
The beneficial effects of the utility model are: by the outer ring at needle stand the needle stand sheath is set, makes between the link restraining line needle stand and needle stand sheath of syringe needle, make syringe needle be difficult for double swerve, improve the stable of syringe needle.
Description of drawings
Below in conjunction with accompanying drawing this utility model is further specified.
Fig. 1 is the structural representation that partly cuts open of the present utility model;
Wherein: 1, syringe, 2, shank, 3, needle stand, 4, the needle stand sheath, 41, screw thread.
The specific embodiment
By reference to the accompanying drawings this utility model is further described now.The sketch map that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with this utility model.
A kind of steady type syringe as shown in Figure 1, comprise syringe 1 and the shank 2 that matches with syringe 1, shank 2 front ends are provided with the rubber piston suitable with syringe 1 inwall, syringe 1 front end is provided with the needle stand 3 for connecting needle, syringe 1 front end also is provided with needle stand sheath 4, needle stand 3 is positioned at needle stand sheath 4, and the outer ring face of needle stand 3 and the inner ring of needle stand sheath 4 are formed for placing the groove of syringe needle.
By the outer ring at needle stand 3 needle stand sheath 4 is set, makes between the link restraining line needle stand 3 and needle stand sheath 4 of syringe needle, make syringe needle be difficult for double swerve, improve the stable of syringe needle.
In order to make fixing more stable of syringe needle, the inner ring face of needle stand sheath 4 is provided with screw thread 41, like this needle stand just can be connected with the external screw thread syringe needle, make more stable that syringe needle fixes.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on the description, must determine its technical scope according to the claim scope.
