Abstract
Description
Technical Field
[0001] This utility model belongs to the field of stationery technology, and in particular relates to a fun neutral pen. Background Technology
[0002] A gel pen, also known as a "neutral ink ballpoint pen," is a writing instrument that combines the characteristics of ballpoint pens and water-based pens, using neutral ink as the writing medium. Neutral ink is an ink with a viscosity between oil-based and water-based inks. Therefore, gel pens possess the advantages of ballpoint pens, such as smooth writing and resistance to drying out, as well as water-based pens, such as clear writing and vibrant colors.
[0003] In real life, ballpoint pens are mainly divided into retractable and non-retractable types. When using retractable ballpoint pens at work or school, many people often press the pen cap to extend and retract the pen tip to relieve pressure. However, existing retractable ballpoint pens make a sound when pressed, which can easily disturb people around them.
[0004] Therefore, we have proposed a fun neutral pen. Utility Model Content
[0005] The purpose of this invention is to address the drawback of existing telescopic gel pens, which make noise when pressed and easily disturb those around them, and to propose a fun gel pen.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A fun ballpoint pen, including:
[0008] The lower housing has an upper housing connected to its top end via a thread, and the inner sides of the lower and upper housings are provided with pen refills;
[0009] The upper housing has a groove on the top outer wall, a screw is rotatably installed in the groove, a rotating wheel is fixedly sleeved on the outer wall of the screw, the bottom end of the screw extends to the inner side of the upper housing and forms a threaded engagement with the push block, and the push block is slidably installed in the inner cavity of the upper housing and abuts against the pen refill;
[0010] The lower housing is provided with an elastic reset mechanism for pushing the pen refill back to its original position.
[0011] The top of the upper shell is fixedly connected to a connecting shell. The outer wall of the connecting shell is provided with a through hole, and its inner cavity is provided with a fixing rod. A rotatable movable block is sleeved on the fixing rod, and the outer wall of the movable block is provided with several patterned areas.
[0012] In one possible design, the elastic reset mechanism includes a mounting tube fixedly disposed on the inner wall of the lower housing, a lifting ring that can slide axially inside the mounting tube, a spring between the lifting ring and the mounting tube, and the pen refill passing through the lifting ring and the mounting tube and abutting against the surface of the lifting ring.
[0013] In one possible design, two limiting blocks are fixedly provided at the top of the mounting tube.
[0014] In one possible design, a limiting ring is fixedly provided on the inner wall of the upper housing.
[0015] In one possible design, two rubber blocks are fixedly provided on the inner wall of the bottom of the connecting shell, and the bottom of the movable block is provided with a limiting groove that cooperates with the rubber blocks.
[0016] In one possible design, the outer wall of the lower housing is provided with an annular groove, and a rubber sleeve is embedded in the annular groove.
[0017] In one possible design, a pen clip is fixedly provided on the outer wall of the upper housing, and a top cap is threadedly connected to the top of the connecting shell.
[0018] In this application, when adjusting the pen tip extension, the rotating wheel is rotated, which drives the screw to rotate, thereby driving the push block to push the pen tip out of the lower housing. At this time, the pen tip pushes the lifting ring to move, and the spring is in a compressed state. When adjusting the pen tip extension, the rotating wheel is rotated in the opposite direction, thereby driving the push block to reset, and the spring pushes the lifting ring, thereby pushing the pen tip to retract.
[0019] When adjusting the pattern, simply insert your finger through the through hole to rotate the movable block. The rubber block will disengage from the limiting groove and deform in contact with the movable block. When the rubber block aligns with the next limiting groove, it will return to its original shape, preventing the pattern from rotating arbitrarily. The pattern area can be printed with popular cartoon characters, animal patterns, or emoticons from the internet. Multiple movable blocks with different patterns can be customized, and users can adjust and change them according to their own preferences.
[0020] Beneficial effects: The fun ballpoint pen described in this utility model, through the setting of multiple structures such as a rotating wheel, screw and push block, can rotate the rotating wheel to adjust the extension and retraction of the pen tip, thereby achieving the decompression effect, improving fun, and the silent adjustment avoids disturbing others;
[0021] In this utility model, the aforementioned fun ballpoint pen, through the setting of multiple structures such as movable blocks, pattern areas, and rubber blocks, allows for the adjustment of different patterns for viewing during work and study. Furthermore, the movable blocks are detachable, and different styles of patterns can be pre-made for replacement, further enhancing the fun of use.
[0022] In this invention, the pen refill can be adjusted by rotating the wheel to achieve a decompression effect, thus increasing the fun. The silent adjustment avoids disturbing others. Different patterns can be adjusted for viewing while working or studying. Furthermore, the movable block is detachable, and different patterns can be pre-made for replacement, further enhancing the fun of use. Attached Figure Description
