[0008] As a further embodiment of this utility model, a rotating seat is fixedly connected to one side of the support sleeve, and the other end of the buffer spring is fixedly connected to the inside of the support sleeve. The rotating seat facilitates the rotation of the limiting rod.
[0009] As a further embodiment of this utility model, the rotating seat is internally connected to a limiting rod, and both ends of the limiting rod are fitted with limiting rings. The limiting rings serve to limit the movement of the limiting rod.
[0010] As a further embodiment of this utility model, both ends of the limiting rod are rotatably connected to positioning plates, and several sets of stress plates are fixedly connected to the surface of the positioning plates. The stress plates increase the supporting force.
[0011] As a further embodiment of this utility model, one end of the positioning piece is fixedly connected to a mounting plate, and the surface of the mounting plate is provided with four sets of positioning holes in a rectangular array. The positioning holes facilitate positioning and installation.
[0012] As a further embodiment of this utility model, threaded holes are provided on the surfaces of both the positioning plate and the fixing frame, and threaded bolts pass through the interior of the threaded holes. The use of threaded bolts facilitates the installation of the positioning plate and the fixing frame.
[0013] As a further embodiment of this utility model, one end of the rotating shaft is connected to a water inlet pipe, and a groove adapted to the conical roller is provided on one side of the fire hose reel body. The groove facilitates the sliding of the conical roller.
[0014] As a further embodiment of this utility model, a water outlet pipe is provided on the surface of the fire hose reel body, and a nozzle is fixedly connected to one end of the water outlet pipe. The surface of the fire hose reel body is coated with polyurethane wear-resistant coating, and the nozzle facilitates spraying.
[0015] (III) Beneficial Effects
[0016] This utility model provides a wear-resistant and impact-resistant fire hose reel, which has the following beneficial effects:
[0017] 1. This wear-resistant and impact-resistant fire hose reel, through the setting of the sliding component, allows the main body of the fire hose reel to rotate when the personnel pull the water pipe. As it rotates, the conical roller slides in the groove on one side of the main body of the fire hose reel. Since the position of the positioning plate remains unchanged, the positioning plate always supports the fixed frame. In turn, the conical roller rotates stably on the connecting rod in the fixed frame, thereby avoiding friction between the main body of the fire hose reel and the support rod. At the same time, it provides lateral support during rotation to prevent shaking and improve the stability of the fire hose reel.
[0018] 2. This wear-resistant and impact-resistant fire hose reel, through the inclusion of a buffer component, allows for rotation of the main body of the fire hose reel and outward pulling force when personnel pull the hose during use. This, in turn, causes one end of the support rod to slide within the support sleeve, stretching and deforming the buffer spring. The positioning rod slides within the support sleeve and maintains stable movement. The deformation of the buffer spring generates elastic force, pulling the support rod in the opposite direction, thereby offsetting part of the pulling force and preventing excessive pulling force from causing deformation or breakage of the support rod. This reduces the impact of pulling and improves the service life of the fire hose reel. Attached Figure Description

[0025] Please see Figures 1 to 4This utility model provides a technical solution: a wear-resistant and impact-resistant fire hose reel, including a support rod 1. A positioning plate 2 is fixedly connected to one side of the support rod 1. Four sets of sliding components 3 are threadedly connected in a ring array to one side of the positioning plate 2. The sliding components 3 prevent friction between the fire hose reel body 7 and the support rod 1, and provide lateral support during rotation to prevent shaking and improve the stability of the fire hose reel. Two sets of buffer components 4 are fixedly connected to one side of the support rod 1. The buffer components 4 offset part of the tension to prevent excessive tension from causing deformation of the support rod 1. Or break, reduce the impact of pulling, and improve the service life of the fire hose reel. One end of the support rod 1 is slidably connected to the support sleeve 5. The inside of one end of the support rod 1 is sleeved with the rotating shaft 6. The surface of the rotating shaft 6 is rotatably connected to the fire hose reel body 7. The sliding component 3 includes a fixed frame 301 that is threadedly connected to one side of the positioning plate 2 in an annular array. The fixed frame 301 is rotatably connected to the connecting rod 302. The surface of the connecting rod 302 is rotatably connected to the tapered roller 303. The buffer component 4 includes a buffer spring 401 that is fixedly connected to one side of the support rod 1. The inside of the buffer spring 401 is sleeved with the positioning rod 402.
[0026] A rotating seat 8 is fixedly connected to one side of the support sleeve 5, and the other end of the buffer spring 401 is fixedly connected to the inside of the support sleeve 5. The rotating seat 8 facilitates the rotation of the limit rod 9.
[0027] The rotating seat 8 has an internal rotatable connection to a limiting rod 9. Both ends of the limiting rod 9 are fitted with limiting rings 10. The limiting rings 10 limit the position of the limiting rod 9.
[0028] Both ends of the limiting rod 9 are rotatably connected to positioning plates 11. Several sets of stress plates 12 are fixedly connected to the surface of the positioning plates 11. The stress plates 12 are used to increase the supporting force.
[0029] One end of the positioning piece 11 is fixedly connected to the mounting plate 13. The surface of the mounting plate 13 has four sets of positioning holes arranged in a rectangular array. The positioning holes facilitate positioning and installation.
[0030] Both the positioning plate 2 and the fixing bracket 301 have threaded holes on their surfaces, and threaded bolts 14 pass through the inside of the threaded holes. The threaded bolts 14 facilitate the installation of the positioning plate 2 and the fixing bracket 301.
[0031] One end of the rotating shaft 6 is connected to the water inlet pipe 15. A sliding groove adapted to the conical roller 303 is provided on one side of the fire hose reel body 7. The sliding groove facilitates the sliding of the conical roller 303.
[0032] The surface of the fire hose reel body 7 is provided with a water outlet pipe 16, and a nozzle 17 is fixedly connected to one end of the water outlet pipe 16. The surface of the fire hose reel body 7 is coated with polyurethane wear-resistant coating. The nozzle 17 facilitates the spraying of water.
[0033] In this invention, the working steps of the device are as follows:
[0034] First step: When in use, the personnel pull the water pipe 16 to make the fire hose reel body 7 rotate. As it rotates, the conical roller 303 slides in the groove on one side of the fire hose reel body 7. Since the position of the positioning plate 2 remains unchanged, the positioning plate 2 always supports the fixing frame 301, and the conical roller 303 rotates stably on the connecting rod 302 in the fixing frame 301.
[0035] The second step: When in use, the personnel pull the water pipe 16, causing the fire hose reel body 7 to rotate and have an outward pulling force, which in turn drives one end of the support rod 1 to slide inside the support sleeve 5, and drives the buffer spring 401 to stretch and deform.
[0036] Third step: The positioning rod 402 slides within the support sleeve 5 and remains stable. The buffer spring 401 deforms to generate elastic force, pulling the support rod 1 in the opposite direction.
