Description

Technical Field

[0001] This utility model relates to the technical field of wheeled fire extinguishers, specifically to a reel-type wheeled fire extinguisher. Background Technology

[0002] At current gas extraction sites, wheeled fire extinguishers are commonly used. When using them, two people usually work together to push or pull the fire extinguisher to the vicinity of the fire. One person removes the horn at the end of the spray hose and unfolds the spray hose, keeping the spray nozzle facing the fire through the handle at the end of the horn. The other person operates the rotary switch handle on the fire extinguisher to extinguish the fire.

[0003] In practical use, it has been found that the spray hose of existing wheeled fire extinguishers is generally wrapped horizontally around the handle of the cart. When firefighters want to remove the spray hose quickly, they are very likely to pull the spray hose upwards, causing the spray hose to come off the handle while it is wrapped, which then twists and deforms, or even causes blockage. This requires extra time to adjust the spray hose, affecting the fire extinguishing efficiency. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing wheeled fire extinguishers where the spray hose is wrapped around the handle and easily twists and deforms when removed, affecting the fire extinguishing efficiency. This invention provides a reel-type wheeled fire extinguisher.

[0005] This utility model provides a reel-type wheeled fire extinguisher, including... A base, on which a first bracket and a second bracket are provided opposite to each other, the first bracket being rotatably connected to a tube winding mechanism, and the second bracket being provided with a limit hole; A fire extinguishing canister, wherein one end of the fire extinguishing canister is provided with a sleeve and the other end of the fire extinguishing canister is provided with a rotating shaft, the hose reel mechanism is detachably connected to the sleeve, the rotating shaft is rotatably engaged with the limiting hole, the sleeve is provided with an operating handle, and the sleeve is provided with an operating window.

[0006] This utility model discloses a reel-type wheeled fire extinguisher. By connecting a hose reel mechanism to the fire extinguisher canister, a convenient storage location for winding the spray hose is provided. This allows the spray hose to be wound or removed during the rotation of the hose reel mechanism, effectively preventing twisting deformation during the removal process and thus improving fire extinguishing efficiency. Furthermore, by adding a rotating shaft to the fire extinguisher canister, the canister and hose reel mechanism can rotate together as a whole, further facilitating the winding or removal of the spray hose. The fire extinguisher can also be rotated and shaken before and after use, making the dry powder extinguishing agent more dispersed and further enhancing the fire extinguishing effect.

[0007] Preferably, the hose reel mechanism includes a baffle, a connecting portion on one side of the baffle, and a connecting shaft on the other side of the baffle. The connecting shaft is rotatably engaged with the first bracket, and the connecting portion is limitedly connected to the sleeve, forming a coil space between the baffle and the fire extinguisher. The hose reel mechanism has a simple structure and can be easily limitedly connected to the sleeve on the fire extinguisher, making the hose reel mechanism and the fire extinguisher an integral unit. Furthermore, the design of this hose reel mechanism does not easily obstruct the original operating window on the fire extinguisher, ensuring the normal use of the fire extinguisher. It can be modified and formed based on existing fire extinguishers at a relatively low cost.

[0008] Preferably, the tube winding mechanism includes two parallel baffles, and the connecting part is disposed between the two baffles, forming a tube winding space between the two baffles.

[0009] Preferably, the connecting part has a cutout corresponding to the operating window. This ensures that the handle on the fire extinguisher can be operated normally after the reel mechanism is installed.

[0010] Preferably, the connecting part is threadedly connected to the sleeve.

[0011] Preferably, the connecting part is provided with a groove and / or a protruding ridge, the connecting part is nested with the sleeve, and the connecting part and the sleeve are connected by a limiting member.

[0012] Preferably, a bearing is provided between the rotating shaft and the limiting hole, and a bearing is provided between the connecting shaft and the first bracket. This allows the entire assembly of the fire extinguisher and the hose reel mechanism to rotate smoothly and reduces rotational resistance.

[0013] Preferably, the baffle is provided with a thickened plate on the side near the first support. This gives the baffle sufficient strength to prevent deformation during the removal or winding of the spray hose.

[0014] Preferably, the base is equipped with wheels and a handrail to facilitate the movement and use of the fire extinguisher.

[0015] Preferably, the fire extinguishing canister is arranged vertically or horizontally on the base.

[0031] Example 1 like Figures 1-2 As shown, a reel-type wheeled fire extinguisher includes a base 1 and a fire extinguishing tank 3. A first support 11 and a second support 12 are provided opposite to each other on the base 1. The first support 11 is rotatably connected to a reel mechanism 2, and the second support 12 is provided with a limit hole. One end of the fire extinguishing tank 3 is provided with a sleeve 31, and the other end of the fire extinguishing tank 3 is provided with a rotating shaft 32. The reel mechanism 2 is detachably connected to the sleeve 31. The rotating shaft 32 is rotatably engaged with the limit hole. An operating handle 33 is provided inside the sleeve 31, and an operating window 34 is provided on the sleeve 31.

[0032] In one or more implementations, such as Figure 1 , Figure 2 As shown, the first bracket 11 and the second bracket 12 can be plate-shaped structural components. The first bracket 11 and the second bracket 12 can be detachably connected to the base 1 by welding or bolts on one side of the plate surface to facilitate the assembly and disassembly of the fire extinguishing tank 3 and the hose reel mechanism 2 on the base 1.

[0033] In one or more implementations, such as Figure 3 As shown, the fire extinguishing canister 3 can be a conventional canister-type dry powder fire extinguisher. A cylindrical sleeve 31 is provided at one end of the fire extinguishing canister 3. An operating handle 33 is provided inside the sleeve 31. An operating window 34 is provided on the sleeve 31, which allows the spray hose to extend and the hand to reach in to operate the operating handle 33. In this embodiment, a rotating shaft 32 is further fixedly provided at the other end of the fire extinguishing canister 3 so as to be rotatably connected to the second bracket 12 through the rotating shaft 32.

[0034] In one or more implementations, such as Figures 4-6As shown, the hose reel mechanism 2 may include a baffle 21, with a connecting part 22 on one side and a connecting shaft 23 on the other side. The connecting shaft 23 is rotatably engaged with the first bracket 11, and the connecting part 22 is limitedly connected to the sleeve 31, forming a coil space between the baffle 21 and the fire extinguisher 3. The hose reel mechanism 2 has a simple structure and can be easily limitedly connected to the sleeve 31 on the fire extinguisher 3, making the hose reel mechanism 2 and the fire extinguisher 3 form an integral whole. Moreover, the setting of the hose reel mechanism 2 does not easily obstruct the original operating window 34 on the fire extinguisher 3, ensuring the normal use of the fire extinguisher 3. It can be modified and formed based on the existing fire extinguisher 3 at a relatively low cost.

[0035] In one or more implementations, such as Figure 7 As shown, the tube winding mechanism 2 may also include two parallel baffles 21, with a connecting part 22 disposed between the two baffles 21, forming a coil space between the two baffles 21.

[0036] In one or more implementations, such as Figures 4-7 As shown, the connecting part 22 is provided with a hollow part 24 corresponding to the operating window 34. This ensures that the handle on the fire extinguisher 3 can be operated normally after the hose reel mechanism 2 is installed.

[0037] In an optional embodiment, the connecting part 22 is threadedly connected to the sleeve 31.

[0038] Preferred, such as Figures 4-7 As shown, the connecting part 22 can be a cylindrical structure. The connecting part 22 is provided with a hollow part 24 corresponding to the operation window 34. The inner wall of the connecting part 22 is provided with an internal thread, and the outer wall of the sleeve 31 is provided with an external thread. After the connecting part 22 and the sleeve 31 are threadedly connected, the hollow part 24 is aligned and connected with the operation window 34 on the sleeve 31.

[0039] In optional implementations, such as Figures 5-6 As shown, the connecting part 22 is provided with a groove 25 and / or a protrusion 26. The connecting part 22 is nested with the sleeve 31, and the connecting part 22 and the sleeve 31 are connected by a limiting member 4.

[0040] Preferably, the connecting part 22 can be a cylindrical structure, and the inner wall of the connecting part 22 can be provided with a groove 25 along the axial direction. The sleeve 31 can be a cylindrical structure used to cover the handle on an existing fire extinguisher 3. A convex rib 26 along the axial direction is welded to the outer wall of the sleeve 31. When connecting the connecting part 22 and the sleeve 31, it is only necessary to align the groove 25 and the convex rib 26. Compared with the threaded connection method, it is easier to ensure that the hollow part 24 on the connecting part 22 is aligned with the operating window 34 on the sleeve 31.

[0041] Preferably, the connecting part 22 can also be a partially cylindrical structure. After the connecting part 22 and the sleeve 31 are engaged by the protrusion 26 and the groove 25, they are connected by limiting parts 4 such as screws and pins that are inserted radially into the sleeve 31, so as to realize the limiting connection between the connecting part 22 and the sleeve 31. This ensures that the operating window 34 on the connecting part 22 and the sleeve 31 are misaligned, so as to avoid affecting the normal operation of the handle on the fire extinguisher 3.

[0042] In one or more embodiments, a bearing may be provided between the rotating shaft 32 and the limiting hole, and a bearing may be provided between the connecting shaft 23 and the first bracket 11. This allows the entire assembly of the fire extinguishing canister 3 and the hose reel mechanism 2 to rotate smoothly, reducing rotational resistance.

[0043] In one or more embodiments, a thickened plate 5 is provided on the side of the baffle 21 near the first support 11. This gives the baffle 21 sufficient strength to prevent deformation during the removal or winding of the spray hose.

[0044] In an optional embodiment, the thickened plate 5 may be a metal plate welded to one side of the baffle 21, and its thickness is greater than that of the baffle 21. The connecting shaft 23 may be welded to the thickened plate 5.

[0045] In one or more embodiments, the base 1 may be an L-shaped structural member with a vertical plate and a bottom plate, with a walking wheel 13 at the bottom of the bottom plate and a handrail at the top or rear of the vertical plate to facilitate the movement and use of the fire extinguisher.

[0046] In optional implementations, such as Figure 1 As shown, the fire extinguisher 3 can be installed vertically on the base plate.

[0047] In optional implementations, such as Figure 2 As shown, the fire extinguisher 3 can be installed horizontally on the base plate.

[0048] This embodiment of a reel-type wheeled fire extinguisher provides a convenient storage location for winding the spray hose by connecting a hose reel mechanism 2 to the fire extinguishing tank 3. This allows the spray hose to be wound or removed during the rotation of the hose reel mechanism 2, effectively preventing twisting deformation during the removal process and thus improving fire extinguishing efficiency. Furthermore, by adding a rotating shaft 32 to the fire extinguishing tank 3, the fire extinguishing tank 3 and the hose reel mechanism 2 can rotate together as a whole, further facilitating the winding or removal of the spray hose. The fire extinguishing tank 3 can also be rotated and shaken before and after use, making the dry powder extinguishing agent more dispersed and further enhancing the fire extinguishing effect.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
