[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-4 This utility model provides a technical solution: a fire rescue hose dragging trainer, including a hose dragging trainer connecting base plate 1, a limiting sleeve 6 that is limited and snapped onto the upper surface of the hose dragging trainer connecting base plate 1, a fixed limiting support rod 5 that is fixedly connected to the inner ring surface of the limiting sleeve 6, and a hose dragging mechanism 3 that is installed on the upper surface of the limiting sleeve 6.
[0020] The hose dragging mechanism 3 includes a plug rod 305, which is snapped onto a limiting sleeve 6. A fixing block 301 is fixedly connected to the side surface of the limiting sleeve 6. A cylindrical guide rod 302 is plugged into the inner ring surface of the fixing block 301. A return spring 308 is fixedly connected to the side surface of the cylindrical guide rod 302. A pull ring 304 is fixedly connected to the side surface of the cylindrical guide rod 302. A plug block 303 is fixedly connected to the side surface of the cylindrical guide rod 302. A fixing plate 307 is attached to the upper surface of the plug rod 305. A mounting plate 307 is installed on the upper surface of the fixing plate 307. The water tank body 309 has a water hose 311 fitted around its outer surface. A connecting shaft 312 is movably connected to the upper surface of the water tank body 309. A sealing cover 314 is fixedly connected to the upper surface of the connecting shaft 312. A push handle 315 is installed on the upper surface of the sealing cover 314. A water inlet pipe 313 is installed on the upper surface of the water tank body 309. A discharge pipe 316 is fixedly connected to the side surface of the water tank body 309. A retaining plug 317 is inserted into the inner surface of the discharge pipe 316. A push handle 315 is also installed on the upper surface of the water tank body 309. The fire hose has a water inlet pipe 319. When the user needs to use the fire hose dragging training device, they need to push open the sealing cover 314 using the push handle 315. After pushing open the sealing cover 314, water can be injected into the water tank body 309 through the water inlet pipe 313, and then water can be injected into the surrounding water hose 311 through the water inlet pipe 319. After water injection, when pulling simulation is required, the user needs to grasp the end of the surrounding water hose 311 and pull it outward along the limiting pull sleeve 310. The limiting sleeve 6 limits the insertion rod 305. The water tank body 309 can be rotated as a whole, which allows the water hose 311 wrapped around the water tank body 309 to be pulled. This allows the user to simulate training by pulling the water hose when the water tank body 309 is full. When it is necessary to weigh the water tank body 309, the pull ring 304 needs to be pulled to remove the cylindrical guide rod 302 and the plug block 303 from the plug rod 305. This allows the plug rod 305 and the water tank body 309 to be pulled off the limiting sleeve 6. This allows the user to perform efficient weighing to achieve a unified standard and then formulate assessment standards.
[0021] Furthermore, a limiting extraction sleeve 310 is fixedly connected to the upper surface of the main base plate 1 of the water hose dragging trainer, and the surrounding water hose 311 passes through the limiting extraction sleeve 310 and is matched in size with the surrounding water hose 311. The surrounding water hose 311, which passes through the limiting extraction sleeve 310 and is matched in size with the surrounding water hose 311, makes it convenient for the user to pull and limit the surrounding water hose 311.
[0022] Furthermore, a mounting positioning plate 2 is fixedly connected to the side surface of the main base plate 1 of the hose dragging trainer, and the mounting positioning plate 2 is arranged around the main base plate 1 of the hose dragging trainer as the center point. The mounting positioning plate 2 arranged around the main base plate 1 of the hose dragging trainer as the center point makes it convenient for the user to install the main base plate 1 of the hose dragging trainer as a whole.
[0023] Furthermore, the upper surface of the mounting positioning plate 2 is provided with a positioning opening 4, and there are multiple positioning openings 4. The multiple positioning openings 4 make it convenient for users to install the mounting positioning plate 2 with bolts.
[0024] Furthermore, an operating handle 318 is installed on the side surface of the snap-fit plate 317, and the operating handle 318 is connected to the water tank body 309 through the snap-fit plate 317, the discharge pipe 316, and the water tank body 309. The operating handle 318, which is connected to the water tank body 309 through the snap-fit plate 317, the discharge pipe 316, and the water tank body 309, makes it convenient for the user to connect the water tank body 309 and the operating handle 318.
[0025] Furthermore, the inner ring surface of the plug rod 305 is provided with a snap-fit opening 306, and the snap-fit opening 306 and the plug block 303 are structurally compatible. The snap-fit opening 306, which is structurally compatible with the plug block 303, facilitates the user to use and limit the snap-fit of the plug block 303.
[0026] Working principle: When the user needs to use this fire rescue hose dragging training device, the sealing cover 314 needs to be pushed open by the push handle 315. After the sealing cover 314 is opened, water can be injected into the water tank body 309 through the water inlet pipe 313, and then water can be injected into the surrounding hose 311 through the hose injection pipe 319. After water injection, when pulling simulation is required, the user needs to grasp the end of the surrounding hose 311 and pull it outward along the limiting extraction sleeve 310. The limiting sleeve 6 limits the insertion rod 305, thus... The water tank body 309 can be rotated as a whole, which allows the water hose 311 wrapped around the water tank body 309 to be pulled. This allows the user to simulate training by pulling the water hose when the water tank body 309 is full. When it is necessary to weigh the water tank body 309, the pull ring 304 needs to be pulled to remove the cylindrical guide rod 302 and the plug block 303 from the plug rod 305. This allows the plug rod 305 and the water tank body 309 to be removed from the limit sleeve 6. This allows the user to perform efficient weighing to achieve a unified standard and then formulate assessment standards.
[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
