Description

Rotary pen

Technical Field

The utility model relates to an office supplies especially relates to a rotatory pen.

Background

When people use ball pens, gel pens and the like to write in daily life, the problem that the pen core is not filled with ink and needs to be replaced is often encountered, if the whole pen is replaced, the pen container is wasted, generally, the pen core in the pen container is directly replaced, because different pen containers have different lengths, when the pen core is replaced, the pen core with the length corresponding to the pen container is replaced according to the length of the pen container, and if the pen core is too long or too short, the pen core cannot be installed in the pen container, so that normal writing cannot be carried out.

SUMMERY OF THE UTILITY MODEL

The present invention is directed to a rotary pen, which solves one or more problems of the prior art and provides at least one of the advantages of the present invention.

The utility model provides a solution of its technical problem is:

a rotary pen, comprising: the pen container is internally connected with a movable cover in a sliding manner, the movable cover is provided with a limiting cavity with a downward opening, and the movable cover can move along the length direction of the pen container; the adjusting sleeve is rotatably connected to the top end of the pen container, an internal thread section is arranged on the inner wall of the adjusting sleeve, an external thread section is arranged on the outer wall of the movable cover, and the internal thread section and the external thread section are connected in a matched mode; and the pen point is detachably connected to the bottom end of the pen container.

The technical scheme at least has the following beneficial effects: when the pen core is too long to install the pen core, the adjusting sleeve can be rotated, the rotating direction of the adjusting sleeve is taken as the forward direction, and the adjusting sleeve can be rotated reversely to lower the movable cover so as to push the pen core downwards out of the pen core when the pen core is too short to extend out of the pen core, so that the utility model is suitable for the pen cores with different lengths, is more flexible to use, and can tightly push the pen core on the pen core by utilizing the movable cover so as to reduce the jumping of the pen core in the writing process, further improving the use experience.

As a further improvement of the above technical solution, a spring is disposed in the adjusting sleeve, one end of the spring abuts against an inner top wall of the adjusting sleeve, and the other end of the spring abuts against a top surface of the movable cover. The spring provides pretightening force for the movable cover, so that the external thread section and the internal thread section are matched more tightly, when an external pen core is arranged in the pen container and in the using process, the movable cover bears upward force, and the spring applies downward force to the movable cover, so that the state of the movable cover is not easy to change.

Because the rotation stopping ring can only slide along the length direction of the pen container but can not rotate, when the adjusting sleeve needs to rotate, the rotation stopping ring is far away from the follow-up ring on the adjusting sleeve, after the adjusting sleeve rotates, the rotation stopping ring is close to the follow-up ring, the clamping teeth and the clamping grooves are mutually matched and connected, the rotation stopping ring and the follow-up ring are mutually attracted to keep the matching state of the clamping teeth and the clamping grooves, and the rotation of the adjusting sleeve can be limited by utilizing the mutual matching of the clamping teeth and the clamping grooves, so that the height of the movable cover in the pen container is better ensured not to change.

As a further improvement of the technical scheme, a plurality of first limiting pieces are arranged on the inner wall of the pen point along the circumference of the center line of the pen point in an array mode, and a bottom limiting space is defined among the first limiting pieces. The bottom limiting space surrounded by the first limiting sheet can be used for better limiting the bottom of the pen core, and the stability of the pen core in the using process is further improved.

As a further improvement of the technical scheme, a plurality of second limiting pieces are arranged on the inner wall of the adjusting sleeve along the circumference of the center line of the adjusting sleeve in an array mode, and a top limiting space is defined between the second limiting pieces. The top limit space surrounded by the second limit sheet can be used for better limiting the head of the refill, and the stability of the refill in the using process is further improved.

As a further improvement of the above technical solution, the second limiting piece is provided with a stepped notch near the bottom corner of the adjusting sleeve. The spacing space of head that the echelonment breach on the spacing piece of a plurality of seconds formed has a plurality of sizes that hold, can correspond the refill that matches different external diameter, with the refill insert the spacing space of head can, the outer wall of refill can with the spacing piece of second closely butt, utilize the spacing space of head to fix the head of refill.

As a further improvement of the above technical scheme, the utility model discloses still include the pen cover, pen cover detachably cup joint in the top of pen container, the nib is located in the pen cover. The pen cap can be covered on the head of the pen container to protect the pen core.

As a further improvement of the technical scheme, the pen point is matched and connected with the pen container through threads. The pen point can be quickly assembled and disassembled from the pen container through threads.
