Abstract

The present invention relates to a canister fixing unit for a hood-type gas mask. The present invention comprises: a tubular cylinder exposed from the inside to the outside of a hood provided with a ventilation hole on the front side thereof through the ventilation hole, and having a female screw on the inner circumferential surface of the cylinder so that a protruding portion on a canister having a screw is coupled thereto, and having a stopper protrusion for hooking onto the inner surface of the hood; an external ring positioned on the exterior of the hood for coupling to the cylinder, and provided with a hole through which the cylinder is inserted; a fixing means for fixing a portion of the external ring to the cylinder; and a locker for preventing reverse rotation of the canister coupled to the cylinder to prevent the canister from separating from the cylinder. The canister coupled to the cylinder is fixed by means of assembly through the fixing means.

Description

technical field [0001] The present invention generally relates to a canister fixing assembly for a hood-shaped gas mask for fixing a canister to a hood-shaped gas mask, and more specifically, a hood-shaped gas mask for easily fixing components of a canister to a turban canister fixing assembly. Background technique [0002] When a fire broke out in a subway or a large building, people on the scene preferentially choose to wear a turban-shaped gas mask (also known as an emergency rescue gas mask) and escape from the scene. [0003] Bandana-shaped gas masks as described come in a variety of materials and shapes, but typically the canister is mounted to a fire-reflecting aluminum coating or a heat-resistant, heat-resistant fabric (e.g., aramid fiber) that blocks fire. or aluminum-coated flame-resistant fabric, etc.) on the scarf made of. [0004] The turban-shaped gas mask is as figure 1 As shown in the figure, it includes: a headscarf 1, the upper hole L1 is provided with a...
