Description

Anti-pressure automatic pen module

This creation relates to a pressure-resistant automatic pen module design, especially a pressure-resistant module design suitable for pencil pen refills and atomic refills, such as writing pens, which makes the anti-pressure module of such automatic pens easier. Manufacturing and assembly, the entire anti-pressure automatic pen module is designed for the user's improper and excessive force through the elastic compression sheath related structure to form a more stable and reliable cushioning and compression function to prevent the pen tip from breaking.

In the existing automatic pen structure design, the pen core structure can usually be assembled into a pressing pen after being modularly combined, and separately produced by the pressing pen and the automatic pen core module, thereby improving production efficiency. However, in such a structure including an automatic pen new module, such as the Taiwan New Patent Publication No. 498860, the combination process of some main components such as a copper bundle, a movable claw, and a damping is quite troublesome and time consuming.

Afterwards, through the continuous improvement of the manufacturer's design, there is an automatic pen module design that is more suitable for rapid production and assembly, including the applicant's new Taiwanese patent M389035 "Anti-pressure pen with elastic structure", the entire automatic pen module In addition to having superior module performance, it can also make such automatic pen writing, through the preset pressure-resistant structure without causing the writing force to be too large, resulting in the advantage of the broken core, but it is used to form a compressive effect. The elastic element and the inner core tube are two separate elements, which may cause assembly failure and unstable buffering action.

That is why the applicant further provides improved solutions, such as Taiwan's new patents. M420439 "Improved Compression Pen", in addition to the compression sheath is a one-piece molded component, which makes the assembly of the puncture-resistant pen easier, and can achieve the stabilization effect of the elastic buffering action, but at the end of the compression sheath The set elastomer also has process complexity, and the entire automatic pen compression module structure is still not perfect.

The purpose of this creation is to provide a pressure-resistant automatic pen module, which makes the anti-pressure module of such an automatic pen easier to manufacture and assemble, and makes the entire anti-pressure automatic pen module more effective for the user's improper use. Stable and reliable cushioning and compression function.
