Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, and in particular to a window sill mounting and fixing device for a variable direction fire hose. Background Technology

[0002] Fire hoses are devices used to deliver and spray water during firefighting operations. They control the fire through their spraying function and are a key tool for fire safety. In building fire scenarios, windowsills provide stable support. Fixing fire hoses on windowsills can avoid the physical exhaustion of holding the hoses for a long time and keep firefighters away from dangerous areas. Therefore, fixing fire hoses on windowsills has become an important application of fire hoses in specific rescue scenarios.

[0003] In existing technologies, fire hose mounting devices on windowsills use fixed clamping components to hold the fire hoses, which makes it easy for the fire hoses to be restricted in direction, creating blind spots in fire suppression and making it difficult to adapt to different fire scenarios. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a variable-direction fire hose window sill mounting and fixing device, which aims to improve the problem that fire hoses are easily restricted in direction adjustment, resulting in fire extinguishing blind spots and difficulty in adapting to different fire scenarios.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a variable-direction fire hose nozzle window sill mounting and fixing device, comprising a first fixing box, a first turntable rotatably connected inside the first fixing box, a connecting block fixedly connected to the upper surface of the first turntable, a first fixing plate fixedly connected to the upper surface of the connecting block, a second fixing box fixedly connected to the inner wall of the first fixing plate, a second turntable rotatably connected inside the second fixing box, a clamping block fixedly connected to the outer wall of the second turntable, a worm gear fixedly connected to the outer wall of the second turntable, a worm gear meshing with the tooth end of the worm gear, a first handle fixedly connected to the outer wall of the worm gear, a damping column threadedly connected to the other end of the second fixing box, and a rotating assembly provided on the lower surface of the first turntable.

[0006] Preferably, the rotating assembly includes a vertical shaft, the upper surface of which is fixedly connected to the lower surface of the first turntable, a gear fixedly connected to the outer wall of the vertical shaft, a rack meshing with the tooth ends of the gear, a first lead screw connected to the internal thread of the rack, and a second handle fixedly connected to the outer wall of the first lead screw.

[0007] Preferably, the outer wall of the worm gear is rotatably connected to the inside of the first fixed plate, and the outer wall of the damping column is fixedly connected to the inside of the clamping block at the other end.

[0008] Preferably, the outer wall of the vertical shaft is rotatably connected to the inside of the first fixed box, and the outer wall of the first lead screw is threadedly connected to the inside of the first fixed box.

[0009] Preferably, a first slide rail is fixedly connected to the lower surface of the first fixed box, a first moving block is slidably connected to the outer wall of the first slide rail, an X-shaped bracket is rotatably connected to the inner wall of the first moving block, a first fixed block is rotatably connected to the outer wall of the X-shaped bracket, a second moving block is rotatably connected to the outer wall of the X-shaped bracket, a second slide rail is slidably connected to the inside of the second moving block, a base is fixedly connected to the lower surface of the second slide rail, and a second fixed block is rotatably connected to the outer wall of the X-shaped bracket.

[0010] Preferably, a limiting block is fixedly connected to the upper surface of the base, a second lead screw is threadedly connected to the inside of the limiting block, a connecting plate is rotatably connected to the outer wall of the second lead screw, a second fixing plate is rotatably connected to the outer wall of the second lead screw, and a third handle is fixedly connected to the outer wall of the second lead screw.

[0011] Preferably, the upper surface of the first fixing block is fixed to the lower surface of the first fixing box, and the lower surface of the second fixing block is fixedly connected to the upper surface of the base.

[0012] Preferably, the outer wall of the connecting plate is fixedly connected to the outer wall of the second movable block, and the outer wall of the second fixed plate is fixedly connected to the outer wall of the base.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, by rotating the first handle, the worm gear is driven to rotate, thereby causing the clamping blocks on both sides to rotate synchronously under the action of the second turntable and the damping column. In addition, by rotating the second handle, the first lead screw is driven to rotate, which causes the rack and gear to drive the first turntable to rotate, and then drives the clamping blocks on both sides to rotate. Finally, the fire hose can be used in a different direction, which improves the flexibility and accuracy of the fire hose. It can be adapted to different fire scenarios and does not require manual fixing to avoid fatigue.

[0015] 2. In this utility model, by starting and rotating the third handle, the lead screw is rotated, causing the connecting plate to slide on the second slide rail. This causes the X-shaped bracket to retract under the action of the rotation of the inner walls of the second moving block, the first moving block, the second fixed block, and the first fixed block, thereby raising the position of the first fixed box. This allows for adjustment of the height of the clamping block, thus avoiding the safety hazard of the user's center of gravity becoming unstable due to frequent adjustments of body posture.

Detailed Implementation

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figure 1 , Figure 2 and Figure 3An embodiment of this utility model provides a variable direction fire hose sill mounting and fixing device, including a first fixing box 1, a first turntable 2 rotatably connected inside the first fixing box 1, a connecting block 3 fixedly connected to the upper surface of the first turntable 2, a first fixing plate 4 fixedly connected to the upper surface of the connecting block 3, a second fixing box 5 fixedly connected to the inner wall of the first fixing plate 4, a second turntable 6 rotatably connected inside the second fixing box 5, a clamping block 7 fixedly connected to the outer wall of the second turntable 6, a worm gear 8 fixedly connected to the outer wall of the second turntable 6, a worm 9 meshing with the tooth end of the worm gear 8, a first handle 10 fixedly connected to the outer wall of the worm 9, a damping column 11 rotatably connected to the other end of the second fixing box 5, and a rotating assembly provided on the lower surface of the first turntable 2;

[0025] Specifically, rotating the first handle 10 causes the worm 9 to rotate, which in turn drives the worm wheel 8 to rotate through the meshing action with the worm 9. This, in turn, causes the second turntable 6 to rotate the clamping block 7. Since the fire hose is positioned between the clamping blocks 7 on both sides, the clamping block 7 causes the damping column 11 on the other side to rotate. The first fixing box 1 provides rotational support for the first turntable 2, the first turntable 2 provides fixed support for the connecting block 3, the connecting block 3 provides fixed support for the first fixing plate 4, the first fixing plate 4 provides fixed support for the second fixing box 5, and the second fixing box 5 restricts and guides the worm 9, causing it to rotate along the inner wall of the second fixing box 5 and preventing it from falling off during rotation. The lever 9 provides fixed support for the first handle 10. The second fixed box 5 restricts the second turntable 6 and the damping column 11, preventing them from falling off during rotation. The second turntable 6 restricts the worm gear 8 and the clamping block 7, preventing the worm gear 8 from changing position during rotation. The damping column 11 is located inside the second fixed box 5. Due to sufficient friction between the damping column 11 and the second fixed box 5, and in conjunction with the worm gear 8 and worm 9 on the other side, the fire hose can rotate up and down, changing the longitudinal spray position while ensuring that the hose does not change position, thereby improving the flexibility of the fire hose. The lower surface of the first turntable 2 is equipped with a rotating component for adjusting the lateral direction of the fire hose.

[0026] Reference Figure 4 The rotating assembly includes a vertical shaft 12, the upper surface of which is fixedly connected to the lower surface of the first turntable 2. A gear 13 is fixedly connected to the outer wall of the vertical shaft 12. A rack 14 is meshed with the tooth end of the gear 13. A first lead screw 15 is threadedly connected to the inside of the rack 14. A second handle 16 is fixedly connected to the outer wall of the first lead screw 15.

[0027] Specifically, manually rotating the second handle 16 causes the first lead screw 15 to rotate, which in turn drives the rack 14 to move. The first fixing box 1 restricts the rack 14, ensuring it can only move linearly without rotating. The meshing of the rack 14 and gear 13 causes the gear 13 to rotate, which in turn drives the vertical shaft 12 and the first turntable 2 to rotate. The vertical shaft 12 provides fixed support for the gear 13, ensuring that the gear 13 and rack 14 are always in mesh. The vertical shaft 12 also provides fixed support for the first turntable 2, ultimately causing the connecting block 3 on the upper surface of the first turntable 2 to rotate. This, in turn, causes the first fixing plate 4, the second fixing box 5, the second turntable 6, the damping column 11, and the clamping blocks on both sides to rotate along the central axis of the second turntable 6. This allows the fire hose to rotate left and right, changing the lateral spraying position, thus further improving the flexibility and accuracy of the fire hose. It can adapt to different fire scenarios, reduce blind spots in firefighting, and eliminate the fatigue caused by prolonged manual fixing.

[0028] Reference Figure 2 , Figure 3 and Figure 4 The outer wall of the worm gear 9 is rotatably connected to the inside of the first fixed plate 4, and the outer wall of the damping column 11 is fixedly connected to the inside of the clamping block 7 at the other end; the outer wall of the vertical shaft 12 is rotatably connected to the inside of the first fixed box 1, and the outer wall of the first lead screw 15 is threadedly connected to the inside of the first fixed box 1.

[0029] Specifically, the first fixed plate 4 restricts the worm 9. By rotating the worm 9 inside the first fixed plate 4, the position of the worm 9 does not change when the worm wheel 8 is rotated and subjected to force, so that the worm wheel 8 and the worm 9 always remain in a meshed state. The damping column 11 provides fixed support for the clamping block 7. The first fixed box 1 provides rotational support for the vertical shaft 12 and restricts the first lead screw 15, so as to prevent the first lead screw 15 from falling off when it rotates.

[0030] Reference Figure 1 and Figure 5A first slide rail 17 is fixedly connected to the lower surface of the first fixed box 1. A first moving block 18 is slidably connected to the outer wall of the first slide rail 17. An X-shaped bracket 19 is rotatably connected to the inner wall of the first moving block 18. A first fixed block 20 is rotatably connected to the outer wall of the X-shaped bracket 19. A second moving block 21 is rotatably connected to the outer wall of the X-shaped bracket 19. A second slide rail 22 is connected to the inner sliding block of the second moving block 21. A base 23 is fixedly connected to the lower surface of the second slide rail 22. A second fixed block 24 is rotatably connected to the outer wall of the X-shaped bracket 19. A second fixed block 24 is fixedly connected to the upper surface of the base 23. A limit block 25 is connected to the second lead screw 26 via an internal thread. A connecting plate 27 is rotatably connected to the outer wall of the second lead screw 26, and a second fixing plate 28 is rotatably connected to the outer wall of the second lead screw 26. A third handle 29 is fixedly connected to the outer wall of the second lead screw 26. The upper surface of the first fixing block 20 is fixed to the lower surface of the first fixing box 1, and the lower surface of the second fixing block 24 is fixedly connected to the upper surface of the base 23. The outer wall of the connecting plate 27 is fixedly connected to the outer wall of the second moving block 21, and the outer wall of the second fixing plate 28 is fixedly connected to the outer wall of the base 23.

[0031] Specifically, by rotating the third handle 29, the second lead screw 26 is rotated, thereby causing the connecting plate 27 to slide along the outer wall of the second lead screw 26. This, in turn, causes the second moving blocks 21 on both sides to slide along the upper surface of the base 23 along the outer wall of the second slide rail 22 under the constraint of the limiting block 25. The base 23 provides fixed support to the limiting block 25. The second fixed plate 28 and the limiting block 25 restrict the second lead screw 26, preventing it from falling off during rotation. The second moving blocks 21 restrict the connecting plate 27, and their outer walls are fixedly connected to the outer wall of the connecting plate 27, restricting the connecting plate 27 to only perform linear motion on the outer wall of the second lead screw 26 and preventing it from rotating. The limiting block 25 restricts the connecting plate 27, preventing... The connecting plate 27 slides away from the outer wall of the second lead screw 26. The base 23 provides fixed support for the second slide rail 22. When the second moving block 21 slides, it pushes the outer wall of the X-shaped bracket 19 to rotate on the inner walls of the second moving block 21, the first fixed block 20, the first moving block 18, and the second fixed block 24, and pulls the first moving block 18 to slide along the lower surface of the first fixed box 1 on the outer wall of the first slide rail 17, causing the X-shaped bracket 19 to retract. The first slide rail 17 and the second slide rail 22 provide sliding support for the first moving block 18 and the second moving block 21, respectively. When the X-shaped bracket 19 retracts, it raises the position of the first fixed box 1, thereby adjusting the height of the clamping block 7 and preventing the user from becoming unstable due to frequent changes in body posture, which could pose a safety hazard.

[0032] Working principle: When it is necessary to adjust the spray direction of the fire hose, rotating the first handle 10 causes the worm gear 9 fixed inside the first handle 10 to rotate. The worm gear 9 drives the worm wheel 8 to rotate through meshing, thereby driving the second turntable 6 to rotate along the axis of the worm wheel 8. This causes the clamping block 7 fixed on the outer wall of the second turntable 6 and the clamping block 7 fixed on the outer wall of the damping column 11 on the other side to rotate synchronously, thereby adjusting the longitudinal direction of the fire hose. In addition, rotating the second handle 16 causes the first lead screw 15 to rotate, driving the rack 14 to slide along the inner wall of the first fixed box 1. Through meshing, the rack 14 is fixed on the outer wall of the vertical shaft 12. The gear 13 on the wall rotates, which in turn drives the first turntable 2 fixed on the upper surface of the vertical shaft 12 to rotate. When the first turntable 2 rotates, the connecting block 3, the first fixing plate 4, and the second fixing box 5 rotate synchronously along the central axis of the first turntable 2. Finally, the second turntable 6, the damping column 11, and the clamping blocks on both sides rotate along the central axis of the worm gear 8, which plays the role of adjusting the longitudinal direction of the fire hose. By using the fire hose in a variable direction, the flexibility and accuracy of the fire hose can be improved, achieving the effect of adapting to different fire scenarios, reducing fire extinguishing blind spots, and eliminating the fatigue caused by long-term manual fixing.

[0033] When the height of the fire hose needs to be adjusted, the second lead screw 26 fixed to the inner wall of the third handle 29 is rotated by turning the third handle 29, thereby causing the connecting plate 27 to slide along the outer wall of the second lead screw 26 under the restriction of the limiting block 25. This causes the second moving blocks 21 fixed on both sides of the outer wall of the connecting plate 27 to slide against the upper surface of the base 23 on the outer wall of the second slide rail 22. This, in turn, pushes the X-shaped bracket 19 to rotate on the inner walls of the second moving block 21, the first fixed block 20, the first moving block 18, and the second fixed block 24. This pulls the first moving block 18 to slide against the lower surface of the first fixed box 1 on the outer wall of the first slide rail 17. Finally, the X-shaped bracket 19 retracts, thereby raising the position of the first fixed box 1. This achieves the effect of adjusting the height of the clamping block 7, thus avoiding the safety hazard of the user's unstable center of gravity due to frequent adjustments of body posture.

[0034] In other words, when using this device, it can not only improve the flexibility and accuracy of fire hoses and adapt to various fire scenarios, but also eliminate the need for long-term manual fixing, thus avoiding the safety hazard of the user's unstable center of gravity.
