Description

一种按压自锁结构以及采用该结构的按压笔Pressing self-locking structure and pressing pen adopting the structure 技术领域Technical field
本发明涉及按压自锁技术领域，更具体地说，涉及一种按压自锁结构。The present invention relates to the technical field of press self-locking, and more specifically, to a press self-locking structure.
背景技术Background technique
按压自锁结构应用于生活中的方方面面，如插座开关、按压手电筒开关、按压写字笔等现有的按压自锁结构在使用过程中为了方便使用通常只需要用较小的力度就能触发下压按钮，使用时不小心触碰到该按钮时，整个装置启动，对于应用于涉电方面的开关按钮时，容易导致不必要的能耗浪费，且对于年纪小的孩童来说，经常来回反复按压生活的开关按钮，按压次数过多容易使其的使用寿命降低，对于按压笔来说在使用或携带过程中外界物品不小心按压到按压笔后端的按压件时，容易使笔芯的笔头露出，进而笔油容易沾染到外界物品上，同时外界物品也容易对笔头造成磨损，有可能使笔珠掉落导致书写过程中漏油。The pressing self-locking structure is used in all aspects of life, such as socket switch, pressing flashlight switch, pressing writing pen, etc. The existing pressing self-locking structure usually only needs a small amount of force to trigger the depression during use in order to facilitate the use. Button, when the button is accidentally touched during use, the whole device will start up. When applied to the switch button for electricity, it will easily lead to unnecessary waste of energy consumption, and for young children, it is often pressed back and forth repeatedly. Too many times of pressing the switch button of life can easily reduce its service life. For the pressing pen, when external objects accidentally press the pressing part at the back of the pressing pen during use or carrying, it is easy to expose the tip of the pen core. Furthermore, the pen oil is easily contaminated on external objects, and at the same time, the external objects are also likely to cause abrasion on the pen tip, which may cause the pen ball to fall and cause oil leakage during the writing process.
发明内容Summary of the invention
1. 要解决的技术问题1. Technical problem to be solved
针对现有技术中存在的问题，本发明的目的在于提供一种按压自锁结构，它可以按压按压件来实现滑动连接件在右框体中的轴向移动，进而促使滑动连接件带动外接部件移动，以实现外接部件的使用和未使用两种状态，操作简单方便，灵活性较强，且在外界作用力较小时，按压件不易在右框体中向下活动，进而不易导致整个装置的触发，装置保持在未使用状态，从而减少了外界误触作用下而引起的不必要的麻烦。本发明的第二个发明目的在于提供一种上述带按压自锁结构的笔。In view of the problems in the prior art, the purpose of the present invention is to provide a pressing self-locking structure, which can press the pressing piece to realize the axial movement of the sliding connection piece in the right frame, thereby prompting the sliding connection piece to drive the external component Move to realize the use and unused states of the external components. The operation is simple and convenient, the flexibility is strong, and when the external force is small, the pressing piece is not easy to move downwards in the right frame, and it is not easy to cause the entire device to fail. When triggered, the device remains in an unused state, thereby reducing unnecessary trouble caused by false touches from the outside world. The second objective of the present invention is to provide the above-mentioned pen with a pressing and self-locking structure.
