[0021] In the following, embodiments of the hose fixing structure of the compressed oxygen self-rescuer detector of the present utility model will be described with reference to the accompanying drawings.

[0022] Figures 1-4 Shown is a hose fixing structure of a compressed oxygen self-rescuer detector according to an embodiment of the present utility model, including a gas detector 1. At the top of the front side of the gas detector 1, a protective cover 2 is rotatably connected. On both sides of the top of the protective cover 2, circular grooves 3 are provided. On both sides of the top of the protective cover 2, a turning plate 4 is rotatably connected. On one side of the turning plate 4, a tube winding column 5 is provided. At the top of the turning plate 4, a rotatable knob 8 is provided through. One end of the knob 8 is fixedly connected to the tube winding column 5. On the surface of the tube winding column 5, a jack 10 is provided. Inside the cavity of the jack 10, a sealing plug 11 is fixedly connected. One end of the hose 9 penetrates into the cavity of the gas detector 1 and is sleeved on the surface of the sealing plug 11. Through the cooperation of the jack 10 and the sealing plug 11, one end of the hose 9 is limited, thus facilitating the user to wind the hose 9 and avoiding the hose 9 from becoming scattered during the winding process. At the top and bottom of the surface of the tube winding column 5, anti-detachment plates 6 are fixedly connected. Between the two anti-detachment plates 6, a hose 9 wound around the surface of the tube winding column 5 is provided. On the top of the protective cover 2, a fixing component 7 is provided. The fixing component 7 includes a fixing shell 71 fixedly connected to the center of the top of the protective cover 2. On both sides of the fixing shell 71, a limiting card 72 is provided through. On the side of the turning plate 4 close to the fixing shell 71, a limiting slot 73 adapted to the limiting card 72 is provided. Inside the cavity of the fixing shell 71, a spring 75 is provided. The two ends of the spring 75 are respectively welded to the two limiting cards 72. On both sides of the top of the fixing shell 71, rectangular sliding grooves 74 are provided. The limiting card 72 is slidably connected inside the rectangular sliding groove 74. Through the setting of the fixing component 7, the cooperation of the limiting card 72 and the limiting slot 73 plays a role in limiting and locking the turning plate 4, enabling the turning plate 4 to drive the tube winding column 5, the anti-detachment plates 6 and the hose 9 to be stably stored in the cavity of the circular groove 3. At the same time, with the cooperation of the spring 75 and the fixing shell 71, the limiting card 72 can actively and accurately engage in the cavity of the limiting slot 73.

[0023] Working principle: When the utility model is in use, the user inserts one end of the hose 9 into the inner cavity of the jack 10 and sleevs the hose 9 on the surface of the sealing plug 11. Then the user rotates the knob 8. During the rotation of the knob 8, the winding column 5 and the anti-detachment plate 6 are driven to rotate, so that the hose 9 can be wound and wound around the surface of the winding column 5. After the winding is completed, the user pushes the flip plate 4, causing the flip plate 4 to rotate, and making the winding column 5, the anti-detachment plate 6 and the hose 9 enter the inner cavity of the circular groove 3. The end of the flip plate 4 close to the fixed shell 71 first contacts the limit card 72 and exerts extrusion on the limit card 72, causing the limit card 72 to slide and compress the spring 75. After the flip plate 4 rotates to the horizontal state, under the elastic pushing action of the spring 75, the limit card 72 is engaged in the inner cavity of the limit card slot 73 to limit and lock the flip plate 4, so that the winding column 5, the anti-detachment plate 6 and the hose 9 can be stably fixed in the inner cavity of the circular groove 3. When the hose 9 needs to be used, the user presses the two limit cards 72 at the same time, causing the limit card 72 to disengage from the inner cavity of the limit card slot 73, and rotates the flip plate 4 to remove the hose 9 from the surface of the winding column 5.

[0024] In summary: For the hose fixing structure of the compressed oxygen self-rescuer detector, through the combined use of the winding column 5 and the anti-detachment plate 6, the hose 9 is wound. Then, through the combined use of the flip plate 4 and the fixing assembly 7, the wound hose 9 is stably fixed in the inner cavity of the circular groove 3, so as to achieve the purposes of strong fixing, integrated design and convenient winding.
