Abstract
The utility model discloses a prevent syringe that syringe needle pine takes off, including cylinder and syringe needle, the cylinder front end is provided with the arrangement head, settle the head to include big footpath section of being connected with the cylinder and the path section of being connected with big footpath section, big footpath section and path section are cylindricly, the global articulated pawl that is provided with of path section, the syringe needle includes connecting portion and pjncture needle, connecting portion include the overcoat in big footpath section and with big footpath section threaded connection's first linkage segment and the second linkage segment of being connected with first linkage segment, be provided with the cylinder hole in the second linkage segment, circumference evenly is provided with the ratchet teeth that matees with the pawl on the cylinder pore wall. The syringe of this structure in the use, can avoid the syringe needle pine to take off.
Description
Technical field
This utility model relates to medical instruments field, is specifically related to a kind of syringe preventing syringe needle from getting loose.
Background technology
The syringe of existing structure comprises syringe and syringe needle, described syringe front end is provided with arrangement head, described syringe needle is placed on to settle head outer and utilize frictional force to realize syringe needle and is connected with arrangement the firm of head, and the advantage of this connected mode is that structure is simple, convenient disassembly between syringe and syringe needle.But this connected mode exists syringe needle and settles the drawback easily got loose between head, brings very large not convenient property to user, especially in injection process, if syringe needle getting loose with settling head, not only can leak medicinal liquid, also can bring very large misery to patient.
Utility model content
In view of this, the purpose of this utility model improves with settling the connected mode of head the syringe needle of prior art, provides a kind of syringe preventing syringe needle from getting loose.
This utility model is solved the problem by following technological means: a kind of syringe preventing syringe needle from getting loose, comprise syringe and syringe needle, described syringe front end is provided with arrangement head, described arrangement head comprises the large footpath section be connected with syringe and the path section be connected with large footpath section, large footpath section and path section are cylindric, hingedly on the side face of described path section be provided with ratchet, described syringe needle comprises connecting portion and puncture needle, described connecting portion comprises and is coated at large footpath section and the first linkage section be threaded with large footpath section and the second linkage section be connected with the first linkage section, cylindrical hole is provided with in described second linkage section, described cylinder hole wall last week is to being evenly provided with the hook tooth mated with ratchet.
Further, described puncture needle is fixedly connected with the second linkage section.
Further, described first linkage section and the second linkage section one-body molded.
The beneficial effects of the utility model: the syringe preventing syringe needle from getting loose of the present utility model, comprise syringe and syringe needle, described syringe front end is provided with arrangement head, described arrangement head comprises the large footpath section be connected with syringe and the path section be connected with large footpath section, large footpath section and path section are cylindric, hingedly on the side face of described path section be provided with ratchet, described syringe needle comprises connecting portion and puncture needle, described connecting portion comprises and is coated at large footpath section and the first linkage section be threaded with large footpath section and the second linkage section be connected with the first linkage section, cylindrical hole is provided with in described second linkage section, described cylinder hole wall last week is to being evenly provided with the hook tooth mated with ratchet.The syringe of this structure, in use, can avoid syringe needle to get loose.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further described.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is A-A schematic diagram.
Detailed description of the invention
Below with reference to accompanying drawing, this utility model is described in detail, as shown in Figure 1-2: a kind of syringe preventing syringe needle from getting loose, comprise syringe 1 and syringe needle, described syringe front end is provided with arrangement head, described arrangement head comprises the large footpath section 31 be connected with syringe and the path section 32 be connected with large footpath section, large footpath section and path section are cylindric, hingedly on the side face of described path section be provided with ratchet 4, described syringe needle comprises connecting portion and puncture needle 23, described connecting portion comprises and is coated at large footpath section and the first linkage section 21 be threaded with large footpath section and the second linkage section 22 be connected with the first linkage section, described first linkage section and the second linkage section one-body molded, described puncture needle is fixedly connected with the second linkage section, cylindrical hole is provided with in described second linkage section, described cylindrical hole is communicated with the screwed hole in the first linkage section, described cylinder hole wall last week is to being evenly provided with the hook tooth 5 mated with ratchet.The syringe of this structure, on the one hand, syringe needle is connected with arrangement head thread by the first linkage section, ensure that and firmly connects effect, can not get loose, on the other hand, pawl-and-gearing tooth forms one-directional rotation structure, and syringe needle can only rotate towards the direction of tightening, and is tightening after syringe needle realizes syringe needle and settle head to be firmly connected, syringe needle arranged opposite head can be avoided freely to rotate backward and cause getting loose, further ensure the firm effect connected.In sum, the syringe of this structure, in use, can avoid syringe needle to get loose.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail this utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
