Abstract

The utility model discloses an injecting type refill and an ink injector thereof. The injecting type refill comprises a refill body and a refill needle head which is connected at the lower end of the refill body. Internal threads are arranged at the tail end of the refill body, external threads which are matched with the inner threads of the refill body are arranged at the upper end of the refill needle head, and after the refill body is filled with ink, the refill needle head is connected at the tail end of the refill body. The injecting type refill and the ink injector thereof have the advantages that due to the injecting type refill and the ink injector which is used for injecting the ink into the injecting type refill, when no ink exists in the refill body, the refill needle head of the refill can be dismounted, after the ink is contained in an injector body, the ink can be injected into the refill body through a matching needle head body, through the arrangement, the structure is simple, using is convenient, after the ink in the refill runs out, the ink can be directly injected into the refill through the injector, using can be continued, and the service life is long.

Description

Injecting type pen core and printing ink syringe thereof

Technical field

The utility model relates to a kind of daily study article, especially a kind of injecting type pen core and printing ink syringe thereof.

Background technology

Estimate according to learning experiences, each high school senior 80 water fillables of approximately using up in a year, that national annual high school senior more than one hundred million water fillables of can using up, and these water fillable overwhelming majority are finished and are all thrown away, however they but be difficult to process as rubbish, the plastic tube on pen core and alloy needle point are not recycled utilization, it is very waste, simultaneously because pen core is short and small, processing is not to facilitate especially, is best solution so extend pen core service life.

Summary of the invention

The utility model is intended to address the above problem, and a kind of injecting type pen core and printing ink syringe thereof are provided, and it has overcome water fillable short drawback in service life, and its technical scheme that adopts is as follows:

A kind of injecting type pen core, comprise pen core and the pen core syringe needle that is connected to the pen core lower end, the end of pen core is provided with internal thread, and the upper end of pen core syringe needle is provided with the external screw thread that matches with the internal thread of pen core, rushes in the end that the pen core syringe needle is connected to after printing ink pen core in pen core.

A kind of printing ink syringe of injecting printing ink for the injecting type pen core, comprise syringe body and adaptive spike body, be provided with piston in syringe body, the lower end of syringe body is provided with externally threaded dispensing end, adaptive spike body comprises that one is used for the link that is connected with the dispensing end of syringe body, is provided with the internal thread that matches with the external screw thread of dispensing end on link; Link below is provided with an injection head, and the periphery of injection head is provided with the external screw thread that matches with the internal thread of pen core, can inject printing ink in pen core by adaptive spike body after holding printing ink in syringe body.

The utlity model has following advantage:

Due to the injecting type pen core that arranges and the printing ink syringe of injecting printing ink for the injecting type pen core, the pen core syringe needle of detachable lower pen core when pen core does not have printing ink, can inject printing ink in pen core by adaptive spike body hold printing ink in syringe body after, arrange thus, simple in structure, easy to use, in pen core, printing ink uses rear directly with continuing use, long service life after injector to inject.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, injecting type pen core of the present utility model and printing ink syringe thereof are described in further detail.

As shown in Figure 1, injecting type pen core of the present utility model, comprise pen core 1 and the pen core syringe needle 2 that is connected to pen core 1 lower end, the end of pen core 1 is provided with internal thread, the upper end of pen core syringe needle 2 is provided with the external screw thread that matches with the internal thread of pen core 1, rushes in the end that pen core syringe needle 2 is connected to after printing ink pen core 1 in pen core 1.

As shown in Figure 2 and Figure 3, a kind of printing ink syringe of injecting printing ink for the injecting type pen core, comprise syringe body 5 and adaptive spike body 6, be provided with piston 4 in syringe body 5, the lower end of syringe body 5 is provided with externally threaded dispensing end 7, adaptive spike body 6 comprises that one is used for the link 8 that is connected with the dispensing end 7 of syringe body 5, is provided with the internal thread that matches with the external screw thread of dispensing end 7 on link 8; Link 8 belows are provided with an injection head 9, and the periphery of injection head 9 is provided with the external screw thread that matches with the internal thread of pen core, and holding in syringe body 5 can be by adaptive spike body 6 to the interior injection printing ink of pen core 1 after printing ink.

In use, as shown in Figure 4, pen core 1 is connected with syringe body 5 by adaptive spike body 6, and piston 4 pushes printing ink under the effect of pressure F, and it is injected in pen core 1 by adaptive spike body 6.Wherein, the external screw thread of adaptive spike body 6 has multiple different model, can connect different pen core 1.

The above is illustrated the utility model with way of example, but the utility model is not limited to above-mentioned specific embodiment, and all any change or modification of doing based on the utility model all belong to the claimed scope of the utility model.
