Description

Technical Field

[0001] This utility model relates to the field of fire-fighting equipment technology, and in particular to a fixing device for fire hose reels. Background Technology

[0002] Fire hose reels are important fire-fighting equipment, mainly used for quickly reeling in and storing fire hoses. Fire hose reels are usually composed of reel supports, rotating shafts, handles, and housings. They are mostly made of metal or high-strength plastics, which have corrosion-resistant and wear-resistant properties. Fire hose reels can effectively protect fire hoses from damage by the external environment and extend the service life of the fire hoses.

[0003] After installation, fire hose reels can rotate via a fixed shaft and bushing. While this installation method increases the flexibility of the reel, there is a possibility that the reel may rotate due to impact even when it is not needed to rotate. This could increase the time required to retrieve and reload the fire hose. Therefore, a fixing device for fire hose reels is needed to solve these problems. Utility Model Content

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.

[0047] This utility model provides, for example Figure 1-4 The fire hose reel fixing device shown includes a reel body 1, a connecting plate 2, a bushing 3, two fixing plates 4, a fixing shaft 5, a mounting plate 6, and a fixing mechanism 7. The connecting plate 2 is fixedly connected to the front of the reel body 1, the bushing 3 is fixedly connected to one side of the connecting plate 2, the two fixing plates 4 are respectively disposed above and below the bushing 3, the fixing shaft 5 is fixedly connected between the two fixing plates 4, the bushing 3 is rotatably sleeved on the outer wall of the fixing shaft 5, the mounting plate 6 is fixedly connected to the back of the two fixing plates 4, the front of the mounting plate 6 has four mounting holes arranged in a rectangular array, and the fixing mechanism 7 is disposed on the front of the mounting plate 6. The fixing mechanism 7 is used to restrict the rotation of the bushing 3 and fix the position of the reel body 1.

[0048] The fixing mechanism 7 includes a ring 71, multiple rotation-limiting holes, a fixing block 72, a long through hole, a short through hole, a rotation-limiting rod 73, a rotating block 74, an annular extrusion groove, a ball groove, a movable ball 75, a reset assembly, and a force-applying assembly. The ring 71 is fixedly sleeved on the outer wall of the bushing 3. Multiple rotation-limiting holes are arranged in a ring array on the top of the ring 71. The number of rotation-limiting holes can be changed according to actual needs. The fixing block 72 is fixedly connected to the top of one of the fixing plates 4. The long through hole is opened on the top of the fixing block 72, and the short through hole is opened on the top of one of the fixing plates 4. The inner diameters of the long through hole and the short through hole are the same. The rotation-limiting rod 73 is slidably sleeved on the inner diameters of the long through hole and the short through hole. The bottom end of the limiting rod 73 is movably sleeved with the corresponding limiting hole cavity. The rotating block 74 is rotatably connected to the top of the fixed block 72. The annular extrusion groove is opened at the bottom of the rotating block 74, and the top of the inner wall of the annular extrusion groove is inclined. The ball groove is opened at the top of the limiting rod 73. The movable ball 75 is movably embedded in the inner cavity of the ball groove. The movable ball 75 is used to increase the smoothness of the movement of the limiting rod 73 driven by the annular extrusion groove. The reset component is set outside the limiting rod 73. The reset component is used to drive the limiting rod 73 to automatically perform a reset movement. The force application component is set on one side of the rotating block 74. The force application component is used to facilitate the application of force to drive the rotating block 74 to rotate and also saves more effort.

[0049] The reset assembly includes an annular groove, a reset ring 76, and a reset spring 77. The annular groove is formed on the inner wall of the elongated through hole. The reset ring 76 is fixedly sleeved on the outer wall of the rotation limiting rod 73. The reset spring 77 is sleeved on the outside of the rotation limiting rod 73. One end of the reset spring 77 is fixedly connected to the top of the inner wall of the annular groove, and the other end of the reset spring 77 is fixedly connected to the top of the reset ring 76. The reset spring 77 can undergo elastic deformation, thereby driving the reset ring 76 and the rotation limiting rod 73 to automatically perform a reset movement, which improves the convenience of operation.

[0050] The force-applying assembly includes an inner rod 78, a force-applying sleeve 79, two limiting grooves, two limiting sliders 710, and an anti-detachment ball 711. The inner rod 78 is fixedly connected to the outer wall of the rotating block 74. The force-applying sleeve 79 is movably sleeved on the outer wall of the inner rod 78. The two limiting grooves are symmetrically opened on the inner wall of the force-applying sleeve 79. The two limiting sliders 710 are slidably sleeved in the inner cavity of the corresponding limiting groove. The two limiting sliders 710 are symmetrically fixedly connected to the outer wall of the inner rod 78. The limiting sliders 710 and the limiting grooves are used to prevent the force-applying sleeve 79 and the inner rod 78 from completely separating. The anti-detachment ball 711 is fixedly connected to one end of the force-applying sleeve 79 and serves as a limiting ball.

[0051] Working principle of this utility model:

[0052] When the fire hose reel needs to be secured, first apply force to the anti-detachment ball 711 to change the relative position between the force-applying sleeve 79 and the inner rod 78. When the position of the force-applying sleeve 79 is convenient for the operator to apply force, it drives the rotating block 74 to rotate clockwise. The clockwise rotating block 74 will drive the rotation-limiting rod 73 to move vertically downward through the annular compression groove at its bottom. During this process, the movable ball 75 moves downward under the compression of the inclined surface of the annular compression groove, while the return spring 77 is stretched and deformed. When the rotation-limiting rod 73 is inserted into the corresponding rotation-limiting hole, the securing work of the fire hose reel is completed. When the fire hose reel does not need to be secured, simply repeat the above operation in reverse. This avoids the fire hose from rotating due to collision when it does not need to rotate, thus improving the stability of the fire hose reel.

[0053] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
