Technical Field
[0001] This utility model relates to the field of writing instrument technology, and in particular to a silent retractable pen. Background Technology
[0002] In the office environment, people are paying more and more attention to a quiet and comfortable working atmosphere. Traditional retractable pens make a clicking sound when pressed to extend or retract, which can be particularly abrupt in quiet offices and meeting rooms, easily disturbing others' attention and affecting work efficiency and meeting order. The emergence of silent retractable pens effectively solves this problem, providing office workers with a quieter writing environment. In addition, in school classrooms and libraries, where students need to concentrate on studying and thinking, the noise of traditional retractable pens can interrupt students' train of thought and affect their learning outcomes, especially in situations requiring a high degree of quiet, such as exams. Silent retractable pens can avoid the interference caused by the sound of pen operation, allowing students to focus more on answering questions.
[0003] As consumers demand higher quality and better user experience from stationery, in addition to basic requirements such as smooth writing and attractive appearance, the silent function has become an important factor for some consumers when choosing retractable pens. They are willing to pay a higher price for silent retractable pens with a better user experience. This has prompted stationery manufacturers to increase their investment in the research and development and production of silent retractable pens. With the continuous advancement of pen manufacturing technology, the silent effect of retracting the pen tip has been achieved by improving the pressing mechanism and using new materials, while ensuring the writing performance and durability of the pen. However, the retractable structure is not stable enough, and the pen tip is prone to shaking and unexpected retraction during use. Utility Model Content

The presence of the spring 10 allows the pen core 12 to receive appropriate elastic support during use, achieving a retraction effect. The support column 11 provides stable support for the entire pen core 12, ensuring the stability of the pen core 12 during extension and retraction.
[0034] Please see the appendix Figure 4 Appendix Figure 5 and attached Figure 6 The noise reduction mechanism 2 includes a soundproof sleeve 201, the outer wall of which is fixedly connected to the inner wall of the pen barrel 1, a shock-absorbing ring 202 fixedly connected to the top of the collar 6, a silent sleeve 203 fixedly connected to the outer wall of the sliding column 5, a shock-absorbing pad 204 fixedly connected to the bottom of the support column 11, and two guide blocks 205 fixedly connected to the bottom of the elastic rod 7, with protective sleeves 206 fixedly connected to the outer walls of the guide blocks 205.
[0035] Specifically, the outer wall of the soundproof sleeve 201 is fixedly connected to the inner wall of the pen barrel 1, thereby effectively isolating noise interference. The top of the collar 6 is connected to the shock-absorbing ring 202, which can absorb and reduce the vibration and noise generated during writing, bringing a quieter writing environment.
