Abstract
The utility model discloses a core rod structure for a safety self-destruction syringe, which is different from the prior art as follows: a locking piece base is arranged at the end part of a rod body, the two, namely the rod body and the locking piece base form an integral structure, at least one small hole is formed in the side wall of the locking piece base, the small hole is communicated with a pipy cavity which is longitudinally arranged in the locking piece base, a locking piece is arranged at the locking piece base, and the lower end of the locking piece is positioned in the pipy cavity and extends to a same horizontal plane with the small hole. A split type steel hook assembly structure is adopted by the core rod structure, and a simplified assembly process step can reduce the difficulty in the assembly process step of a steel hook; and simultaneously, a secondary fixing structure is adopted, so that the stability of the metal steel hook is effectively enhanced, the integral design of a product is reasonable in structure and ingenious in concept, the practicability is very good and the core rod structure has prominent substantive features and significant progress in comparison with the prior art.
Description
Technical field
This utility model relates to technical field of medical, a kind of specifically core bar structure that is used for safe self-breaking syringe, particularly its mechanical connecting structure.
Background technology
Documents, the patent No.: ZL200720067715.4, the applying date: 2007.03.08; Notification number: CN201076648, the patentee: Shanghai DingJianTang biochemistry Science Co., Ltd, this case discloses " a kind of core bar that has the Metallic hook structure "; Comprise: the core bar body, the upper end of core bar body is provided with the column fastener, and column fastener place is socketed with plug; It is characterized in that: said plug place is provided with installing hole, is provided with barbed body in the installing hole.
Visible from above-mentioned documents, traditional steel hook-type core bar structure is that the metallic steel hook directly is assemblied in the core bar end, carries out a glue then from top and fixes, and this kind fit is difficult to the stability of control products.
Summary of the invention
The purpose of this utility model is to provide a kind of core bar structure that is used for safe self-breaking syringe; Product adopts split type steel hook mounting structure and steel hook secondary fixed structure; Effectively increase the stability of steel hook, simplified assembly process, overcome the shortcoming and defect that exists in the prior art.
To achieve these goals; The technical scheme of this utility model is: a kind of core bar structure that is used for safe self-breaking syringe; It comprises the body of rod; It is characterized in that: the upper end of the said body of rod forms locking piece pedestal department of assembly, and the lower end of locking piece pedestal is positioned at locking piece pedestal department of assembly, and locking piece pedestal place is provided with locking piece.
A kind of core bar structure that is used for safe self-breaking syringe, it comprises the body of rod, it is characterized in that: said body of rod end is provided with the locking piece pedestal; Both are integrative-structure; Locking piece pedestal side-walls offers at least one aperture, and the tubular housing that vertically is provided with in this aperture and the locking piece pedestal links, and locking piece pedestal place is provided with locking piece; The lower end of locking piece is positioned at tubular housing, and extends to aperture and be positioned at same horizontal plane.
