[0027] Embodiment

[0028] Refer to Figures 1-6, A protection device for a fire hose, comprising a protection cylinder 1, a connecting ring 2 and a fixing frame 3. The fixing frame 3 is rectangular as a whole, and the fixing frame 3 and the connecting ring 2 are fixedly connected by a connecting rod. The surface of the fixing frame 3 is penetrated with screw holes. The protection cylinder 1 is installed inside the equipment box of the fire truck through the connecting ring 2 and the fixing frame 3. The firefighter can fit the fixing frame 3 against the inside of the equipment box and then use bolts to fix the fixing frame 3 to the inner wall of the equipment box.

[0029] A connecting ring 2 is fixedly connected to the outside of the protection cylinder 1, and a fixing frame 3 is fixedly connected to one end of the connecting ring 2. A display lamp mechanism 4 is fitted and connected to the surface of the protection cylinder 1. A rotating cylinder 5 is fitted and connected to the outside of the protection cylinder 1. A water hose socket 7 is penetrated through the inside of the rotating cylinder 5, and a water hose 6 is fitted and connected to the inside of the water hose socket 7. A water hose limiting rod 8 is fixedly connected to the surface of the water hose 6. A water hose positioning groove 10 is provided inside the water hose socket 7. A water hose positioning block 16 is fixedly connected to the surface of the water hose 6. When using this device, the firefighter can insert the water hose 6 into the inside of the rotating cylinder 5, so that the water hose 6 enters the inside of the inner tank 9 through the water hose socket 7, so that the water hose limiting rod 8 on the surface of the water hose 6 is inserted into the card slot 11, and the water hose positioning block 16 on the surface of the water hose 6 is fitted into the water hose positioning groove 10 on the inner wall of the rotating cylinder 5. Subsequently, the firefighter rotates the rotating cylinder 5, so that the rotating cylinder 5 drives the water hose 6 to rotate inside the inner tank 9. At this time, the water hose limiting rod 8 on the surface of the water hose 6 rotates into the inside of the baffle 13 in the card slot 11, so that the water hose limiting rod 8 rotates to the inside of the baffle 13. Furthermore, the protection cylinder 1 and the rotating cylinder 5 limit the water hose 6 at multiple angles by the way that the water hose limiting rod 8 is stuck into the baffle 13 and the water hose positioning block 16 is stuck into the water hose positioning groove 10, so that the water hose 6 can be stably fixed inside the protection cylinder 1 and the rotating cylinder 5.

[0030] Inside the protective cylinder 1, an inner liner 9 is fitted and connected. At the other end of the inner liner 9, a rotary cylinder 5 is fixedly fitted and connected. The water gun socket 7 is connected to the inner liner 9 in a through manner. Inside the protective cylinder 1, a card slot 11 is fitted and connected, and inside the card slot 11, a touch switch 12 is fitted and connected. One end of the card slot 11 is connected in a through manner to a sliding groove 14, and inside the sliding groove 14, a second touch switch 15 is fitted and connected. Outside the sliding groove 14, a baffle 13 is fixedly connected. When the water gun 6 is inserted into the protective cylinder 1, the water gun limit rod 8 on the outside of the water gun 6 will be inserted into the card slot 11 inside the protective cylinder 1. At the same time, the water gun limit rod 8 will squeeze the touch switch 12 inside the card slot 11, causing the touch switch 12 to trigger the display lamp mechanism 4 on the surface of the protective cylinder 1. Thus, the firefighter can know through the display lamp mechanism 4 that the water gun 6 is normally inserted into the protective cylinder 1. Subsequently, by rotating the rotary cylinder 5, the water gun limit rod 8 is screwed into the sliding groove 14 until the water gun limit rod 8 contacts the second touch switch 15 inside the sliding groove 14. Then, by squeezing the second touch switch 15, the second touch switch 15 is triggered, and the firefighter can know through the information feedback by the display lamp on the surface of the display lamp mechanism 4 that the water gun limit rod 8 is completely screwed into the sliding groove 14.

[0031] The display lamp mechanism 4 as a whole consists of a base and two display lamps fitted on the upper surface of the base. Inside the base, a wire groove is provided, and inside the wire groove, a control wire for controlling the display lamps is provided. The control wires are respectively connected to the second touch switch 15 and the display lamps. There are two display lamps, and the two display lamps respectively correspond to the touch switch 12 and the second touch switch 15.

[0032] The rotary cylinder 5 as a whole is a hollow circular ring, and anti-slip patterns are fixedly connected to the surface of the rotary cylinder 5. Through this design, when the firefighter rotates the rotary cylinder 5, the anti-slip patterns can increase the friction between the rotary cylinder 5 and the palm.

[0033] The water gun socket 7 as a whole is divided into upper and lower parts. The upper part of the water gun socket 7 is fixedly connected to the inner wall of the rotary cylinder 5, and the lower part of the water gun socket 7 is fixedly connected to the inner liner 9. The two parts of the water gun socket 7 are connected by a spring. When taking the water gun, the firefighter can press down the rotary cylinder 5, causing the rotary cylinder 5 to move towards one side of the protective cylinder 1 through the spring at the bottom of the upper part of the water gun socket 7, so that the water gun 6 can be exposed outside the rotary cylinder 5.

[0034] On the surface of the protective cylinder 1, two connecting rings 2 are symmetrically arranged. One end of each of the two connecting rings 2 is fixedly connected to a fixing bracket 3. Through the two connecting rings 2 and the fixing brackets 3, the protective cylinder 1 can be fixed more firmly inside the equipment box.

[0035] It should be noted that the upper surfaces of the tact switch 12 and the second tact switch 15 and the bottom of the water gun limiting rod 8 are all arc surfaces with arcs. When the water gun limiting rod 8 is inserted into the inside of the card slot 11, the water gun limiting rod 8 can more smoothly squeeze the tact switch 12 and the second tact switch 15 inward.

[0036] Working principle: When using this device, a firefighter can insert the water gun 6 into the inside of the rotating cylinder 5, so that the water gun 6 enters the inside of the inner tank 9 through the water gun socket 7, and the water gun limiting rod 8 on the surface of the water gun 6 is inserted into the card slot 11, and the water gun positioning block 16 on the surface of the water gun 6 is fitted into the water gun positioning groove 10 on the inner wall of the rotating cylinder 5. Subsequently, the firefighter rotates the rotating cylinder 5, so that the rotating cylinder 5 drives the water gun 6 to rotate inside the inner tank 9. At this time, the water gun limiting rod 8 on the surface of the water gun 6 rotates into the inside of the baffle 13 in the card slot 11, so that the water gun limiting rod 8 rotates to the inside of the baffle 13. Furthermore, the protection cylinder 1 and the rotating cylinder 5 limit the water gun 6 at multiple angles by the way that the water gun limiting rod 8 is stuck into the baffle 13 and the water gun positioning block 16 is stuck into the water gun positioning groove 10, so that the water gun 6 can be stably fixed inside the protection cylinder 1 and the rotating cylinder 5.

[0037] The above embodiments are the preferred embodiments of the present invention, but the embodiments of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention shall be equivalent replacement methods and are all included in the protection scope of the present invention.

[0038] In the description of the present invention, it should be understood that the terms indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.
