[0028] Reference Figure 1As shown, the utility model provides a technical solution: a high-temperature metal hose with a flame-retardant structure, comprising a hose body 1, a protective device 2 is provided on the arc surface of the hose body 1, and the protective device 2 is provided to prevent the hose body 1 from being burned and damaged, thereby avoiding the hose body 1 being burned and damaged by external flames when the hose body 1 is used in a special environment, resulting in the hose body 1 being unusable, thereby improving the protectiveness of the device, and a dustproof device 3 is provided on one side of the flame-proof cover 201, and the dustproof device 3 is provided to prevent the two ends of the hose body 1 from being dustproof, thereby avoiding dust and impurities from entering the hose body 1 through the two ends of the hose body 1 when the hose body 1 is stored, thereby avoiding the hose body 1 being covered and blocked by dust and impurities, thereby causing the hose body 1 to be difficult to use.

[0029] The specific settings and functions of the protective device 2 and the dustproof device 3 are described in detail below.

[0030] Reference Figure 2 and Figure 3As shown, in this embodiment: the protection device 2 includes a flame retardant hood 201, the flame retardant hood 201 is slidably connected to the circular arc surface of the hose body 1, a flame retardant plate 202 is slidably inserted in the flame retardant hood 201, a handle 203 is fixedly connected to one side of the flame retardant plate 202, two sliding grooves are provided on the surface of the flame retardant hood 201, a plug plate 204 is slidably connected to the inner surface of the sliding groove of the flame retardant hood 201, the surface of the plug plate 204 is slidably connected to the flame retardant plate 202, two fixed rods 205 are fixedly connected to the surface of the flame retardant hood 201, an operating panel 206 is slidably connected to the circular arc surface of the fixed rod 205, a plug rod 207 is fixedly connected to the side of the operating panel 206 close to the flame retardant hood 201, a slot is provided on the surface of the plug plate 204, and when the staff adjusts the hose body After the fire prevention is performed, the operating plate 206 is pushed to make the operating plate 206 slide on the arc surface of the fixing rod 205. At the same time, the operating plate 206 drives the plug rod 207 to move until the plug rod 207 is inserted into the slot of the plug plate 204. At this time, the effect of limiting the sliding of the plug plate 204 is achieved, and the effect of fixing the fireproof plate 202 is achieved, which prevents the fireproof plate 202 from being separated from the fireproof cover 201 due to the external force generated after the hose body 1 is hit by an external force. The end of the fixing rod 205 away from the fireproof cover 201 is fixedly connected to the limiting plate 208. The size of the plug rod 207 is adapted to the size of the slot of the plug plate 204. When the staff pulls the operating plate 206, the operating plate 206 slides on the arc surface of the fixing rod 205. At this time, the limit plate 208 has achieved the effect of limiting the maximum sliding distance of the operating plate 206 on the fixed rod 205, avoiding the situation that the operating plate 206 is separated from the arc surface of the fixed rod 205 due to excessive pulling force when the staff pulls the operating plate 206. The arc surface of the fixed rod 205 is sleeved with a first spring 209, and the two ends of the first spring 209 are respectively fixedly connected to the operating plate 206 and the flameproof cover 201. When the staff releases the operating plate 206, the rebound force of the first spring 209 drives the operating plate 206 to slide on the arc surface of the fixed rod 205. At the same time, the operating plate 206 drives the insertion rod 207 to move until the insertion rod 207 is inserted into the slot of the insertion plate 204. At this time, the first spring 209 increases the insertion rod To ensure the stability of the plug plate 204 when 207 limits the position, a screw 210 is fixedly connected to the side of the flame retardant hood 201 close to the fixed rod 205, and the arc surface thread of the screw 210 is connected to the blocking plate 211. When the staff releases the limit of the plug plate 204 by the plug rod 207, they continue to pull the operating plate 206 until the operating plate 206 moves to the highest point of the fixed rod 205. At this time, the blocking plate 211 is rotated to make the blocking plate 211 rotate on the arc surface thread of the screw 210 until the blocking plate 211 moves to the bottom of the operating plate 206. At this time, the blocking plate 211 has the effect of limiting the movement of the operating plate 206, thereby preventing the operating plate 206 from driving the plug rod 207 to rub against the plug plate 204 too much, thereby causing damage to the plug rod 207.

[0031] Reference Figure 2 and Figure 4 The cam 33 is provided with a plurality of cams 34, each of which is provided with a plurality of cams 35. The cam 33 is provided with a plurality of cams 36, each of which is provided with a plurality of cams 37. The cam 33 is provided with a plurality of cams 37, each of which is provided with a plurality of cams 37.

[0032] Working principle: when the staff needs to perform fire protection on the hose body 1, the legs push the fire hood 201, and the fire hood 201 slides on the arc surface of the hose body 1 until the fire hood 201 covers the hose body 1. At this time, the handle 203 is pushed, and the handle 203 drives the fire resistant plate 202 to slide in the fire resistant plate 201 until the fire resistant plate 201 is closed. At this time, the operating plate 206 is pulled to slide on the arc surface of the fixed rod 205, and the first spring 209 is stretched. At the same time, the operating plate 206 drives the plug rod 207 to move until the plug rod 207 no longer blocks the movement of the plug plate 204. At this time, the operating plate 206 is continued to be pulled until the operating plate 206 moves to the highest point of the fixed rod 205. At this time, the blocking plate 211 is rotated so that the blocking plate 211 is screwed on the arc surface of the screw 210. The blocking plate 211 rotates until the blocking plate 211 moves to the bottom of the operating plate 206, and the plug plate 204 is pushed to move until the plug plate 204 is inserted into the flameproof plate 202, and the blocking plate 211 is rotated again to make the blocking plate 211 rotate on the arc surface thread of the screw rod 210 until the blocking plate 211 is disengaged from the bottom of the operating plate 206. At this time, the resilience of the first spring 209 drives the operating plate 206 to slide on the arc surface of the fixing rod 205, and at the same time, the operating plate 206 drives the plug rod 207 to move until the plug rod 207 is inserted into the slot of the plug plate 204. At this time, the effect of preventing the hose body 1 from being burned and damaged is achieved, and when the hose body 1 is used in a special environment, the external flame burns and damages the hose body 1, resulting in the hose body 1 being unusable, thereby improving the protection of the device.

[0033] When the staff needs to dustproof the two ends of the hose body 1, the driving rod 33 is rotated, and the driving rod 33 moves in the internal thread of the fixing plate 32. At the same time, the driving rod 33 drives the connecting block 34 to move, and the connecting block 34 drives the positioning rod 36 to slide in the fixing plate 32. At the same time, the connecting block 34 drives the dustproof plate 35 to move until the dustproof plate 35 covers one end of the hose body 1. At this time, the effect of dustproofing the two ends of the hose body 1 is achieved, which prevents dust and impurities from entering the hose body 1 through the two ends of the hose body 1 when the hose body 1 is stored, causing the hose body 1 to be covered and blocked by dust and impurities, thereby making the hose body 1 difficult to use.
