Description

[Detailed Description of the Invention] The present invention is intended to provide a safety pin used to prevent erroneous operation of an oxygen generating can (chlorate candle) and to prevent the operating pin from spontaneously coming off due to vibration or the like.

An embodiment of the present invention will be described below based on the drawings. 1 is an oxygen generating can with a built-in candle core, 2 is a striker provided at one end of the oxygen generating can 1, and 3 is a space provided on the outer periphery of the oxygen generating can 1. 4 is a heat insulating tube made of solidified paper tube poured between the oxygen generating can 1 and the paper tube 3, and 5 is a heat insulating tube made of corrugated paper wrapped in several layers around the outer circumference of the paper tube 3. A case body 6 covers the outer periphery of the heat insulating material 5 and extends beyond both ends of the oxygen generating can 1 to form spaces 7 and 8. A mask 9 is provided at the other end of the oxygen generating can 1. A flexible tube 10 is connected between the space 8 and the oxygen outlet, and the flexible tube 10 is rolled into the space 8 and a mask 9 is stored therein. 11 is a stand that supports the oxygen generating can 1, the paper tube 3, the heat insulating tube 4, and the heat insulating material 5 in the space 7; 12 is the operating pin of the striker 2, which moves the striker 2 from the striking core connected to the candle core with the elasticity of the spring; A ring 13 is provided at the rear end of the operating pin 12. 14 is a safety pin inserted into ring 13, 15 is safety pin 1
4 and the connecting end of the flexible tube 10 wound in the space 8 to the mask 9, and is made of thread, wire, or other material. 1
Reference numeral 6 denotes a heat insulating plate that covers the middle part of the outer periphery of the case body 6, and is made of paper or the like, and has a corrugated plate surface. 17 is a heat insulating plate 1 from the upper end of the case body 6.
18 is a bottom lid that is placed over the lower end of the case body 6 and the heat insulating plate 16; 19 is a pull attached to the ring 13 of the safety pin 14; the tip thereof is provided on a part of the bottom cover 18; It can be pulled out from the hole.

In the above configuration, while the mask 9 and the flexible tube 10 are not removed from the space 8, even if an attempt is made to remove the operating pin 12 using the handle 19, the safety pin 14 is inserted through the ring 13 and cannot be removed. When the top cover 17 is removed and the mask 9 is taken out and the flexible tube 10 is stretched out, the string 15 is pulled and the safety pin 14 comes out of the ring 13, so the operating pin 12
will come off. Then, when the operating pin 12 is removed and the striker 2 is operated so as to strike the striking core with the elasticity of the spring, the candle core starts the reaction of generating oxygen, and the generated oxygen passes through the flexible tube 10 and passes through the mask. 9 is involved.

Since the present invention is configured as described above, the operating pin of the oxygen generating can is locked by the safety pin and cannot be removed unless the mask is removed from the case body. It has the advantage of preventing erroneous operation and erroneous operation, and since the lock of the safety pin is automatically released when the mask is removed from the case body, it does not take much time to remove the operation pin.
