Abstract
The utility model relates to an ink-charge injector and can effectively solve the problems that a traditional injector is inconvenient to use in writing instruments industry and the effectiveness is poor. The technical scheme includes a needle cylinder, a push rod and a piston. The push rod is arranged inside the needle cylinder, wherein the rear end of the push rod is protruded from the needle cylinder. The piston is fixed with the needle cylinder by means of interference fit and is arranged at the front end of the push rod. Ink is disposed between the needle cylinder and the piston. A cone-shaped body is mounted at the front end of the needle cylinder and is provided with through holes along the axis in the center. The ink-charge injector has the advantages of being novel and unique in structure, convenient to use, good in effectiveness, easy in process and low in cost.
Description
Technical field
The utility model relates to a kind of black formula syringe that fills.
Background technology
Because Neutral ball-point for ball-point pen and refill for ball-point pen is lightweight, price is low, easy to use, write comfortable feel, and quite be subjected to liking of people, but the service life that is Neutral ball-point for ball-point pen and refill for ball-point pen is all shorter, the life-span that how much has determined pen core of the quantity of ink in the pen core, use the light time when printing ink, pen core has also just been scrapped, not only cause the waste on the material, also environmental pollution is found to use syringe that pen core is filled China ink, to solve the problem of pen core recycling after deliberation, but existing syringe is owing to structural reason, limited its application in system pen industry, the one, the end tapering of syringe is little, and syringe just cooperates with syringe needle, cooperate then too smallly because of tapering with pen core, needing very, length could cooperate with it; The 2nd, injection head divides external diameter excessive, thus can not with gel ink pen, the pen core internal diameter of ball pen etc. is nested, can not be used for being the ink filling of pen refills such as Neutral ball-point for ball-point pen, refill for ball-point pen, thus use inconvenient, weak effect.
Summary of the invention
For above-mentioned situation, for overcoming the prior art defective, the purpose of the utility model just provides a kind of black formula syringe that fills, and can effectively solve syringe uses inconvenient and weak effect in system pen industry problem.
The technical scheme that the utility model solves is, comprises syringe, push rod and piston, and the push rod that stretch out the rear end is housed in the syringe, the front end of push rod has the piston with the syringe interference fit, between syringe and the piston ink is arranged, the front end of syringe has bullet, and the bullet center has through hole vertically.
The utility model novel structure is unique, and is easy to use, effective, easily processing, and cost is low.
Description of drawings
Fig. 1 is the utility model structural front view.
Fig. 2 is the use state diagram of the utility model structure.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.
Provided by Fig. 1-Fig. 2, the utility model comprises syringe, push rod and piston, and the push rod 1 that stretches out the rear end is housed in the syringe 2, the front end of push rod has the piston 3 with syringe 2 interference fit, ink 6 is arranged between syringe and the piston, and the front end of syringe has bullet 4, and the bullet center has through hole 5 vertically.Described bullet 4 inswepts, the rear end is wide; The tapering of described bullet 4 is
α is coning angle, and coning angle is the 7.628-150 degree, and tapering is 0.1333-7.4641.
The utility model is the improvement of carrying out on the basis of injector for medical purpose, increased bullet in its end, after utilizing taper seat and pen core internal diameter fitted seal, add China ink, its structure is substantially identical with common injector for medical purpose, only need and will make the tapering that matches with pen core with the pen core mating part, used syringe adopts taper seat to seal, and the large I of its tapering is according to pen core internal diameter size, tapering adjusts accordingly between 0.1333 ~ 7.4641, in order to can utilize this taper seat to realize and the combining closely of pen core internal diameter, during use, carry out ink 6 filling before, first nib is extracted, syringe is inserted in the ink bottle, spur push rod 1, utilize the interference fit seal of piston 3 and plastic needle cylinder 2, ink 6 is entered in the syringe 2 of plastics, aim at pen core 7 internal diameter inks 6, after filling is finished, the nib installation is gone back, nib is firmly got rid of twice down, wipe the ink 6 be infected with on pen and the syringe off, in order to the next time of usefulness again, namely finish the whole black process that adds.
After the utility model is improved existing syringe, namely can be used for the printing ink filling of the pen cores such as Neutral ball-point for ball-point pen, refill for ball-point pen, so that making pen core can reuse, the utility model utilizes the taper seat of bullet and pen core internal diameter to seal, and suitable tapering is set according to actual needs, with the needs of the pen core that adapts to different tube diameters, utilize the utility model that original disposable pen core is reused, the economize on resources energy, environmental contamination reduction, easy to use, effective.
