Embodiment Construction

[0020] See figure 1 with figure 2 . The safety helmet for self-rescue and escape comprises a cap shell 1, a cap liner 2 and a face shield 3. in:

[0021] The cap shell 1 is hemispherical, firm, smooth and has certain elasticity, has certain anti-shock and puncture function, and it can be supported by materials such as steel. The cap shell 1 is provided with a clean room 11 , a locking button 12 , a tightening guide rail 13 and a fixing part 14 . in:

[0022] The clean room 11 is provided with an air inlet and an air outlet, and a carbon dioxide filter is built in it, which can filter the carbon dioxide in the exhaled gas.

[0023] The locking button 12 is used to lock the mask 3 on the cap shell 1, so that the mask 3 will not fall and unfold when it is folded and stored in the cap shell, and when the locking button 12 is unscrewed, the mask can be removed from the cap shell Let it go. The locking button 12 is arranged on the side of the cap shell 1 so as to be operated...

Abstract

The invention discloses a safety helmet for self-rescue and escape, and aims to provide a safety helmet capable of supplying oxygen to people when an accident occurs in a mine. There is a buffer gap between the cap shell and the cap liner, and the safety helmet for self-rescue and escape also includes a mask that is connected to the cap shell and can be folded in the cap shell. The airtight breathing part that can seal the mouth and the nose of a person is provided with an oxygen delivery tube that can be communicated with the oxygen bottle and an exhalation hose for exhaling gas. The invention can be used in various mine operations.

Description

technical field [0001] The invention relates to a safety helmet, in particular to a safety helmet for self-rescue and escape. Background technique [0002] Since most of the self-rescue and protective equipment equipped in existing coal mines are fixed in a certain position, mine workers usually only rely on a safety helmet worn with them to prevent heavy objects from hitting the brain. Such equipment cannot be quickly used. Therefore, when gas explosions and harmful gas exceed the standard accidents occur in coal mines, underground miners are likely to lose their lives due to lack of oxygen and harmful gas attacks. As a result, once an accident occurs in coal mines, the chances of survival for mine workers are very small. Contents of the invention [0003] The invention provides a safety helmet for self-rescue and escape in order to solve the technical problem in the prior art that underground miners are prone to lose their lives due to lack of oxygen and harmful gas atta...
