Wherein:

1. an ink bag main body; 2. sealing the cover; 3. a rear clamping groove; 4. a seal spring; 5. an external thread convex ring; 6. a first cone; 7. a second cone; 8. a seal ring; 9. and (5) sealing the film.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, a pen ink bag convenient to disassemble includes a cylindrical ink bag main body 1 for storing ink, one end of the ink bag main body 1 is closed and the other end is opened, a rear clamping groove 3 is formed at the closed end of the ink bag main body 1, a sealing spring 4 is fixed in the rear clamping groove 3, the sealing spring 4 is supported inside a pen holder when in use, so that the ink bag main body 1 can be ensured to be tightly attached to the end of a pen, the ink bag main body 1 is prevented from loosening, an external thread convex ring 5 is formed at the open end of the ink bag main body 1, a first cone 6 is formed on the outer end face of the external thread convex ring 5, a second cone 7 is integrally formed at the outer end of the first cone 6, a sealing ring 8 is fixed on the outer end face of the second cone 7, so that the sealing performance can be improved, a sealing film 9 is arranged at the joint of the first cone 6 and the second cone 7 for sealing ink after filling, a sealing cap 2 is installed on the external thread convex ring 5 through threads, the protection capability is improved, and the sealing membrane 9 is prevented from being punctured accidentally.

Specifically, the ink bag main body 1 is made of a transparent material, and thus, the user can know the color of the ink inside the ink bag main body 1 and the remaining amount of the ink conveniently.

Specifically, the diameters of the small ends of the first cone 6 and the second cone 7 are the same, the small ends of the first cone 6 and the second cone 7 are molded together to form a diabolo shape, the first cone 6 and the second cone 7 are made of PE materials, and therefore the first cone 6 and the second cone 7 can deform and expand at the joint during installation and then are in tight fit contact with a fixing table on a pen body, installation and replacement of the ink bag are facilitated, and ink leakage can be avoided by means of mechanical sealing.

Specifically, the inner diameter of the large end of the first cone 6 is the same as the inner diameter of the external thread convex ring 5, the inner diameter of the large end of the first cone 6 is larger than the inner diameter of the small end of the first cone 6 by 0.5-2mm, and due to the arrangement, the ink bag main body 1 can be prevented from shaking left and right after being fixed, and the fixing firmness is not affected.

Specifically, the inner diameter of the large end of the second cone 7 is larger than that of the first cone 6, and the outer diameter of the large end of the second cone 7 is smaller than that of the external thread convex ring 5, so that the ink bag main body 1 can be conveniently mounted, and the influence on the mounting and dismounting of the sealing cover 2 can be avoided.

The working principle is as follows:

during the use, select the ink bag of suitable size, lift off the pen-holder after pulling out original ink bag, take out new ink bag, the closing cap 2 is taken off in the rotation, then aim at the arch of installation ink bag on the pen body of steel pen with second cone 7, the extrusion makes the protruding bursting seal membrane 9 on the pen body of pen hard, strut the contact position of first cone 6 and second cone 7 simultaneously, make ink bag tight fit install on the pen body of steel pen, then guarantee sealing washer 8 and pen body contact, after reinstallating the pen-holder sealing spring 4 support top in the pen-holder and be in the compression state, utilize sealing spring 4 to guarantee that sealing washer 8 and pen-holder hug closely together.
