Detailed Description

The embodiment of the utility model provides an ink storage pen, the ink storage pen includes pen-holder and refill, the pen-holder includes pen container and pen cap, the pen cap includes two piece arc pieces that can move up and down along the inner wall of the lower end of the pen container at least; when the arc sheet moves to the lowest end, the radial direction of the pen point of the pen core is covered by the arc sheet.

In one embodiment, the pen cap comprises two arc sheets, and the two arc sheets are uniformly distributed in the circumferential direction of the pen holder. The structure is simpler due to the design of two pieces. It will be appreciated that three or more sheets are possible, but would increase the cost.

In one embodiment, the pen container comprises a fixed cylinder and a rotating ring, wherein the rotating ring is arranged at the lower end of the fixed cylinder and can rotate relative to the fixed cylinder; the lower end of the rotating ring is provided with an inverted frustum-shaped cavity, the inner wall of the cavity is provided with internal threads, and the outer wall of the arc piece is provided with external threads matched with the internal threads. Therefore, the circular arc sheet can ascend and descend by rotating the rotating ring, namely the rotating ring rotates and does not move axially, so that the circular arc sheet can do rotating motion and move axially, and the circular arc sheet is more convenient and more stable to ascend and descend similar to the motion of a nut screw. It will be appreciated that other arrangements are possible, for example, a sliding slot may be provided in which the circular arc piece moves axially to cover the writing tip, a radial slot may be provided at the upper limit of the circular arc piece to prevent the circular arc piece from sliding downwards during writing, and the circular arc piece may be manually removed from the slot when it is desired to lower the circular arc piece.

The outer circular surface of the circular arc piece can be a part of a circular truncated cone shape, so that the circular arc piece is closer to a circular truncated cone shape when being folded, or can be a part of a cylindrical shape, so that the lower end of the circular arc piece needs to be trimmed, and details are not described.

In one embodiment, the internal thread and the external thread are both triangular threads. The triangular thread has self-locking performance, so the circular arc piece can not slide down freely due to gravity and the like, and the method is the preferred mode.

In one embodiment, the lower end of the fixed cylinder comprises elastic barbs, and the rotating ring comprises an annular groove matched with the elastic barbs; when the rotating ring rotates relative to the fixed cylinder, the elastic barbs limit the axial movement of the rotating ring. Thus, the rotating ring does not move axially when rotating. It will be appreciated that other rotational arrangements that limit axial movement are possible. Here, the elasticity overhead kick owing to have certain elasticity, during the assembly, can directly insert by force, the assembly of being convenient for, because be the overhead kick, but be difficult to deviate from after inserting, guarantee the firm connection between fixed section of thick bamboo and the rotating ring.

In one embodiment, the outer circumferential surface of the rotating ring is provided with knurls. Therefore, a certain friction force is provided, so that the rotation is easier, and it can be understood that the friction force can be increased without arranging other structures, for example, a rubber sleeve can be sleeved on the outer circular surface of the rotating ring.

In one embodiment, the upper end of the barrel further comprises an opening for receiving the refill, and the reservoir pen further comprises a refill cap for filling the opening. Therefore, the refill is convenient to load. This is a common design of existing ink pens and will not be described in detail.

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.

The ink storage pen of the embodiment is a gel ink pen, and it can be understood that other ink storage pens can be the structure of the embodiment; as shown in fig. 1 and 2, the gel-ink pen comprises a pen holder and a pen core 21, wherein the pen holder comprises a pen container and a pen cap, and the pen cap comprises two arc sheets 31 which can move up and down along the inner wall of the lower end of the pen container; when the arc piece 31 moves to the lowermost end, the radial direction of the pen point of the pen core 21 is covered by the arc piece 31. The two arc sheets 31 are uniformly distributed in the circumferential direction of the penholder.

Here, when the two circular arcs 31 move to the lowest end, the radial direction of the pen point of the pen core 21 is not completely covered by the circular arcs 31, that is, the two circular arcs 31 are not completely folded, so that the existing cap of the gel pen is not completely closed due to safety considerations, and the manufacture is more convenient, otherwise, the manufacture precision requirement is high, and the circular arcs are more easily interfered due to complete closure.

In this embodiment, the pen container comprises a fixed container 11 and a rotating ring 12, the rotating ring 12 is arranged at the lower end of the fixed container 11, and the rotating ring 12 can rotate relative to the fixed container 11; the lower end of the rotating ring 12 is provided with an inverted frustum-shaped cavity, the inner wall of the cavity is provided with an internal thread, and the outer wall of the arc piece 31 is provided with an external thread matched with the internal thread. Thus, the circular arc piece 31 can rise and fall more conveniently and stably.

In this embodiment, the outer circular surface of the circular arc piece 31 may be a part of an inverted truncated cone shape, so as to be closer to an inverted truncated cone shape when being folded. Namely, the ring is firstly processed into a circular truncated cone and then divided into two pieces.

In this embodiment, the internal thread and the external thread are both triangular threads. The triangular thread has self-locking properties, so that the circular arc piece 31 cannot slide down freely due to gravity and the like. Of course, the self-locking feature also requires that the threads be manufactured to a certain tolerance fit and not be too tight or otherwise unable to make a helical motion, and will not be described in detail.

In this embodiment, the lower end of the fixed cylinder 11 includes an elastic barb 111, and the rotating ring 12 includes an annular groove 121 matching with the elastic barb 111; when the rotating ring 12 rotates relative to the fixed cylinder 11, the elastic barbs 111 limit the axial movement of the rotating ring 12. Thus, the rotating ring 12 does not move axially when rotating.

In this embodiment, the outer circumferential surface of the rotating ring 12 is provided with knurling (not shown in the drawings). Thus, a certain friction force is provided, and the rotation is easier.

In this embodiment, the upper end of the barrel further includes an opening 13 for receiving the cartridge 21, and the gel pen further includes a cartridge cap (not shown) for filling the opening 13. Thus, the cartridge 21 is easily loaded.

the above-mentioned embodiments further explain the technical problems, technical solutions and advantages of the present invention in detail, it should be understood that the above-mentioned embodiments are only examples of the present invention, and are not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
