Abstract
The utility model discloses a needle bed improved structure of a safe self-destruction syringe. The needle bed improved structure of the safe self-destruction syringe comprises a needle bed body, and the outer wall of the needle bed body is provided with at least one elastic sealing ring which is integrally and seamlessly connected with the needle bed body. The needle bed and the sealing structure on the needle bed are of an integrated connecting structure, the assembling process of the needle bed and the sealing structure is omitted fundamentally, the assembling efficiency of the syringe can be effectively improved, and the connecting sealing performance of the needle bed and a needle tube can be improved to a certain degree.
Description
Technical field
The utility model discloses a kind of safe self-breaking syringe, be specially a kind of needle stand structure-improved of safe self-breaking syringe.
Background technology
In safe self-breaking syringe, the needle point that wherein has a type is to be positioned at syringe endoporus front end by needle stand, at this, because needle stand and syringe form by the plastic material of hard relatively, for the sealing that guarantees that both connect, the general sealing ring of interference fit that arranges between needle stand and syringe, and sealing ring and needle stand are split settings and independently process separately, both need the later stage to carry out assembly connection, in practice, the sealing ring assembling that interference is nested with is more difficult, by manual assembly, can cause work efficiency lower, by machine, assemble very high to the required precision of equipment, and often there will be sealing ring that the phenomenon of sideslip is installed, need shutdown frequently correct and safeguard.
Utility model content
For the problems referred to above, this utility model has designed a kind of needle stand structure-improved of safe self-breaking syringe, needle stand and the hermetically-sealed construction on it adopt integral connecting structure, both assembly processes have fundamentally been omitted, the efficiency of assembling of syringe can be effectively promoted, and the connection sealing of needle stand and syringe can be promoted to a certain extent.
For achieving the above object, this utility model is by the following technical solutions:
A needle stand structure-improved for safe self-breaking syringe, comprises needle stand body, it is characterized in that: described needle stand body outer wall is provided with at least one one and the elastic sealing ring of seamless link.
The hermetically-sealed construction of needle stand of the present utility model and syringe is the sealing ring that is arranged on needle stand body outer wall, sealing ring adopts elastomeric material, be different from the plastic material of needle stand body, both are by two-shot process and one-body molded, fundamentally omit the interference of sealing ring in existing structure and be nested with assembling process, can effectively simplify technique, promote the efficiency of assembling of syringe.
Sealing ring and needle stand body is one-body molded simultaneously, can realize absolute fix and positive confinement between sealing ring and needle stand body, can further promote to a certain extent the connection sealing of needle stand and syringe.
Accompanying drawing explanation
Fig. 1, structural representation of the present utility model.
The specific embodiment
As described in Figure 1, a kind of needle stand structure-improved of safe self-breaking syringe, comprise needle stand body 1, described needle stand body 1 outer wall is directly provided with at least one by two-shot process and the elastic sealing ring 11 that one generates, in the present embodiment, sealing ring 11 is arranged to together, in practice, can need to be arranged to twice or multiple tracks according to sealing property.
With upper sealing ring 11, adopt elastomeric material, it is different from the plastic material of needle stand body 1, sealing ring 11 and needle stand body 1 is by two-shot process and one-body molded, this structure arranges, fundamentally omit the interference of sealing ring and needle stand in existing structure and be nested with assembling process, can effectively simplify technique, promote the efficiency of assembling of syringe.
The integrated formed structure of while sealing ring 11 and needle stand body 1, can realize absolute fix and positive confinement between sealing ring 11 and needle stand body 1, stop the generation of sealing ring 11 deviation phenomenons, can further promote to a certain extent the connection sealing of needle stand and syringe.
The above, it is only better embodiment of the present invention, not the present invention is done to any pro forma restriction, every foundation know-why of the present invention, to any simple modification made for any of the above embodiments, equivalent variations or modification, still belongs in the scope of technical solution of the present invention.
