一种灭火装置安全销
摘要：
本发明涉及一种灭火装置安全销，其包括连接部与连接于连接部下端的卡接头；所述卡接头包括第一弹片以及连接于第一弹片末端且与第一弹片形成夹角的第二弹片；所述第一弹片与第二弹片分别具有自由度；本发明通过设置一种由从不同方向设置的第一弹片和第二弹片组成的卡接头，从而提供了一种构件之间紧密卡接并可靠定位的安全销，本发明的灭火装置安全销充分利用了弹性材料的弹性性能，具有两个自由度的弹性扩张与拉伸实现了灭火装置的安全销卡紧与拔出功能，而且在整个拉出的过程中，形成连续的阻力，使拉出阻力在拉出的全过程中都存在，使得拉出力相对稳定，增强了灭火装置的安全性能。
摘要（英）：

The invention relates to a safety pin of a fire extinguisher which comprises a connecting portion and a fastener connected to the lower end of the connecting portion. The fastener comprises a first elastic piece and a second elastic piece, the second elastic piece is connected to the tail end of the first elastic piece and forms an included angle with the first elastic piece, and both the first elastic piece and the second elastic piece have freedom degrees. The first elastic piece and the second elastic piece arranged in different directions form the fastener, and accordingly the safety pin is capable of realizing close fastening and reliable positioning of components. Elasticity of elastic materials is utilized effectively, and the safety pin of the fire extinguisher is tightened and pulled out by action of elastic expansion and stretching with two freedom degrees. Continuous resistance force is formed and lasts in the whole pulling process and is stable relatively, so that safety performance of the fire extinguisher is enhanced.
