Main purpose of the present utility model is to solve plug easily from the problem that piston main body comes off.
For arriving above-mentioned technical purpose, this utility model provides a kind of piston component, the plug of one end that described piston component comprises piston main body and is sheathed on described piston main body in order to be slidably connected with the inwall of syringe cylinder, described plug and described piston main body one-body molded.
Preferably, described plug adopts silica gel or rubber to make, and described piston main body adopts plastic cement to make.
Preferably, described piston main body and described plug are one-body molded by quadric injection mould.
Preferably, the lateral surface of described piston main body has the embedded surface mutually embedded with described plug, and described embedded surface is that male and fomale(M&F) is arranged.
Preferably, described piston main body comprises push rod and is located at the plunger of described push rod one end, and described plug is sheathed on described plunger.
For arriving above-mentioned technical purpose, this utility model also provides a kind of syringe, described syringe comprises syringe cylinder and piston component, described piston component comprises piston main body and is sheathed on one end of described piston main body and the plug be slidably connected with the inwall of syringe cylinder, described plug and described piston main body one-body molded.
Preferably, described plug adopts silica gel or rubber to make, and described piston main body adopts plastic cement to make.
Preferably, described piston main body and described plug are one-body molded by quadric injection mould.
Preferably, the lateral surface of described piston main body has the embedded surface mutually embedded with described plug, and described embedded surface is that male and fomale(M&F) is arranged.
