Description

Improvement of refill control structure

This creation is related to the improvement of a refill control structure, especially one that can be rotated to push out the refill, which can be used to return the pen to the pen tube when not in use, and prevent the refill from sliding down when the refill is replaced. The improvement of the refill control structure.

Because of the convenience of use, the rotary ball pen has gradually replaced the traditional ball pen in recent years, which is favored by the general consumers. However, the use of the conventional rotary ball pen is to push the refill by the rotation of the upper pipe body. For writing. The applicant has previously designed a rotary ballpoint pen, which comprises a driving unit 1, a refill 2 and an inner tube body 3, a spring 4 and a lower pen tube 5, an upper pen tube 6 and the like, and the pen is rotated by rotating the upper tube body 6. The core 2 is extended by the tip of the lower tubular body 5 for writing. The driving unit 1 comprises a hollow guide sleeve 11, a sleeve 12 and a pushing body 13, and the hollow guiding sleeve 11 is provided with an arc-shaped slope 111. And the arc-shaped slope 111 is provided with a concave portion 112 for facilitating the positioning of the pushing body 13. The sleeve 12 is provided with a vertical hole 121, and the pushing body 13 is provided with a protruding rib 131 for making the protruding rib The 131 is sleeved in the hole 121 of the sleeve 12, slides up and down along the hole 121, and cooperates with the spring 4 disposed under the pen core 2 to push out the refill 2 or return the refill 2 to the pen tube 5. However, since the split hole 121 is open, when the refill 2 is replaced, the pusher 13 is easily slid down. After the applicant has thought about it, after continuous research and experimentation, Yan Mengsheng has improved and prayed that the rotary ball pen is more perfect.

The main purpose of this creation is to provide an improvement of the refill control structure, so that the rotary atomic pen can prevent the refill from falling down to improve the refill control structure when the refill is replaced.

The improvement of the above-mentioned refill control structure comprises a structure of a driving unit, a refill and an inner tube body, and the pen core is extended by the pen tube by a suitable length for writing by rotation; the feature is a driving unit for rotating and pushing out The utility model comprises a hollow guide sleeve, a sleeve and a pushing body, wherein the hollow guiding sleeve is provided with an arc-shaped slope, and the arc-shaped slope is provided with a concave portion for facilitating positioning of the pushing body, the sleeve is provided with a vertical The split hole is provided with a limiting portion at the bottom edge of the split hole, and the pusher body is provided with a protrusion, so that the protruding piece is sleeved in the split hole of the sleeve, and the refill is pushed up or down along the split hole or the refill is returned. In the income pen tube, when the refill is replaced, the limit of the resisting body can be restricted by the limiting portion, so that the pushing body does not slip outward, so as to facilitate the replacement of the refill.

The improvement of the above-mentioned refill control structure, wherein the split hole provided in the sleeve and the upper edge of the protrusion of the pusher body are respectively set as a pointed portion, and the tip is slid upward to the top end of the split hole by the tip The shape is configured to form a position.

Please also refer to Fig. 2 and Fig. 3, which are the three-dimensional exploded view of the rotary pen atomic structure and the three-dimensional exploded view of the driving unit. As shown in the figure, the present invention mainly includes the driving unit 1 and the structure of the refill 2 and the inner tube body 3, the spring 4, the lower pen tube 5, and the upper pen tube 6. The driving unit 1 includes a hollow guiding sleeve 11, a sleeve 12 and a pushing body 13, wherein the hollow guiding sleeve 11 is sleeved and fixed to the upper tube body, and the lower part is provided with an upper part. The lower arc-shaped ramp 111 is provided with a recess 112 at the lowest point of the arc-shaped ramp 111.

The sleeve 12 is provided with a hole 121, and the top edge of the hole 121 is a pointed portion. The bottom edge of the hole 121 is provided with a limiting portion 122. The bottom edge of the pushing body 13 is provided with a stop. The ridge 132 is provided with a rod body 133 at the upper portion, and a protrusion 134 is disposed on the rod body 133, so that the top edge of the protrusion 134 is a pointed portion. The sleeve 12 is sleeved on the arc-shaped slope 111 of the hollow guide sleeve 11, and the thrust body 13 is inserted into the arc-shaped slope 111 from the bottom up, so that the protrusion 134 is cut by the sleeve 12. The hole 121 is exposed, and when the hollow guide sleeve 11 is rotated, the arc-shaped ramp wave 111 can push down the protrusion 134 of the pushing body 13, thereby pushing the pushing body 13 downward, and by the limiting portion. 122 constitutes a limit. After the entire assembly is completed, it is embedded in an inner tube body 3. The refill 2 is fixedly attached to the bottom edge of the urging body 13.

By the combination of the foregoing members, the rotary ballpoint pen is configured to rotate the tubular body 6 above the rotary ballpoint pen, thereby driving the rotation of the hollow guide sleeve 11 of the driving unit 1, so that the thrusting body 13 follows Moving downward, the protrusion 134 is slid along the arc-shaped slope 111, and is engaged with the concave portion 112 at the lowest point of the bottom end of the slope 111 to form a positioning, and the refill 2 is extended from the lower pen tube 5 for writing, and when not When in use, the pen tube 6 above the rotating atom is reversed, and the spring 4 is used to slide the protrusion 134 upward along the arc slope, and the refill 2 is recycled to the lower pen tube. 5, to facilitate carrying, so that the use of the rotary ball pen is more convenient.

In the foregoing, when the refill 2 is replaced, the protrusion 134 of the urging body 13 is slid downward, and the refill 2 is detached, because the bottom edge of the hole 121 of the sleeve 12 is provided with a limit. The portion 122 constitutes a stop for the protrusion 134 so that the urging body 13 does not slip outward, so as to facilitate the replacement of the refill 2 and make the rotary ball pen more practical.

Please refer to Figure 4 for the action state diagram of this creation. Please cooperate with Figure 2, as shown in the figure, when the creation is not in use, the tube 6 above the rotary ball pen is reversed, and the spring 4 is used to slide the protrusion 134 upward along the arc ramp 111. The refill 2 is retracted in the lower pen tube 5.

Please refer to Figure 5 for another action state diagram of this creation. Please cooperate with Figure 2, as shown in the figure, when the creation is in use, the tube 6 above the rotary ball pen is rotated, so that the protrusion 134 of the thrust body 13 is along the hole 121 of the sleeve 12. Sliding downwards, which in turn drives the rotation of the hollow guide sleeve 11 of the driving unit 1 to move the urging body 13 downward, so that the protrusion 134 slides along the arc-shaped slope 111 and engages at the lowest point of the bottom end of the slope 111. The recess 112 is configured to position such that the refill 2 protrudes from the lower pen tube 5 for writing. When the refill 2 is replaced, the limiting portion 122 of the bottom edge of the split hole 121 of the sleeve 12 can form a stop for the protrusion 134, so that the resisting body 13 does not slip outward, thereby enabling The replacement of the refill 2 is more convenient.

The foregoing embodiments are merely illustrative of the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and the details of the present invention are not deviated from the spirit of the present invention.

In summary, the present invention comprises a hollow guide sleeve with an arc-shaped slope, a pusher body movable along the hollow guide sleeve, and a sleeve provided with a split hole and a limit portion to form a refill control structure. Improvement. When the automatic pencil is replaced, the component is prevented from being improperly slipped, and the operation and assembly are more convenient. For a practical design, it is a novelty creation. If you apply for a patent in accordance with the law, you will be punished by the Bureau of Public Information, and you will be granted a patent as soon as possible.
