Description

Technical Field

[0001] This utility model relates to the field of fire protection, and in particular to a water gun fixing device used by firefighters for interior attack. Background Technology

[0002] Firefighters often encounter intense heat and toxic fumes, high-temperature radiation, and sudden explosions during rescue operations in buildings or fires with strong radiant heat. This can result in injuries or fatalities. When conducting interior attacks, firefighters typically carry water hoses and cannot carry heavy equipment such as water cannons. Furthermore, using water hoses for interior attacks or smoke cutting requires firefighters to hold and operate them, preventing them from freeing their hands or moving away from the danger zone. This forces firefighters to work in hazardous locations for extended periods, increasing the probability of injury or death.

[0003] Utility model patent 201721133794 discloses a fire hose fixing bracket, which facilitates fixing the fire hose and adjusting the angle of the fire hose. However, it uses a ball joint connection, which means that after adjusting the angle of the fire hose, it is still necessary to hold the fire hose to maintain its direction, making it impossible to free the hands or move away from the danger point.

Detailed Implementation

[0025] To make the purpose, technical solution and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and examples. Example 1

[0026] like Figures 1-3 The illustrated water gun fixing device for firefighters' interior attack includes a horizontal rod 1. One end of the horizontal rod 1 is fitted with a clamping and fixing mechanism 2 and slidably connected to a first sliding frame 3. The first sliding frame 3 is threadedly connected to a first fixing bolt 4. The first sliding frame 3 is connected to a vertical rotating mechanism 5, which is connected to a horizontal rotating mechanism 6. The horizontal rotating mechanism 6 is connected to a water gun fixing mechanism 7. The other end of the horizontal rod 1 is threadedly connected to a limit bolt 9.

[0027] In use, the clamping and fixing mechanism 2 is clamped and fixed to objects in the fire scene such as windowsills, solid walls, railings, guardrails, and trees. Then, the water gun is clamped and fixed to the water gun fixing mechanism 7. The fixing position of the water gun is then adjusted by the first sliding frame 3 and the first fixing bolt 4. Finally, the direction of the water gun is adjusted by the vertical rotation mechanism 5 and the horizontal rotation mechanism 6 to complete the adjustment and fixing of the water gun. At this time, firefighters can free their hands to carry out other rescue work or evacuate the dangerous scene.

[0028] The transverse rod 1 is a rack; the clamping and fixing mechanism 2 includes a fixed clamping arm 21 at the bottom of one end of the rack and a second sliding block 22 sleeved on the rack. A movable clamping arm 23, which cooperates with the second sliding block 22, is fixedly fixed to the bottom of the second sliding block 22. A rotating shaft 24 is rotatably connected to the second sliding block 22, and a gear 25 and a wrench 26 are fixedly connected to the rotating shaft 24. By turning the wrench, the rack can be rotated, which in turn moves the second sliding block 22 and the movable clamping arm 23, thereby clamping and fixing the fixed clamping arm 21 and the movable clamping arm 23. The wrench 26 utilizes the lever principle to quickly and stably achieve clamping.

[0029] A triangular resistance block 29, which slidably connects to the gear 25, is also rotatably connected to the second sliding block 22. The triangular resistance block 29 is positioned between the gear 25 and the rotation limit block 210. When the wrench 26 applies force, it rotates the rotation limit block 210, causing it to press against the triangular resistance block 29, thereby preventing the gear 25 from reversing and maintaining the applied force. Figure 3 As shown. When it is necessary to remove it, simply rotate the rotation limit block 210 to stop pressing the triangular resistance block 29.

[0030] Both the fixed clamping arm 21 and the movable clamping arm 23 have clamping teeth 27 on their inner sides, and an arc-shaped groove 28 in the middle. The clamping teeth 27 are used to improve the clamping friction, and the arc-shaped groove 28 is convenient for clamping and fixing to tubular objects, such as water pipes, guardrails, etc.

[0031] The vertical rotation mechanism 5 includes a fixed plate 51 fixedly connected to the first sliding frame 3. The fixed plate 51 passes through a second horizontal fixing bolt 52. The second fixing bolt 52 and the nut cooperate to clamp and fix an inverted L-shaped swing arm 53. In this way, by loosening the nut and the second fixing bolt 52, the inverted L-shaped swing arm 53 can swing vertically. After swinging to a suitable position, it is fixed, thus realizing vertical rotation adjustment.

[0032] The lateral rotation mechanism 6 includes a mounting frame 61 fixed to the top of the inverted L-shaped swing arm 53. A worm gear 62 is laterally rotatably connected to the mounting frame 61. The worm gear 62 is connected to a perforated turntable 63. A turbine is meshed with the worm gear 62, and a vertical rotating shaft is fixedly connected to the center of the turbine. A mounting base 64 is fixed to the top of the vertical rotating shaft. Thus, rotating the perforated turntable 63 drives the worm gear 62 to rotate, which in turn drives the turbine to rotate, thereby achieving lateral swing adjustment of the water gun.

[0033] The water gun fixing mechanism 7 includes a fixed semicircular hoop 71 fixed on a fixing base 64, with a movable semicircular hoop 72 hinged to one end of the fixed semicircular hoop 71; connecting pieces 73 are fixed to the other end of the fixed semicircular hoop 71 and the free end of the movable semicircular hoop 72, and a screw is tightened through the connecting piece 73 to fix the water gun 8 between the fixed semicircular hoop 71 and the movable semicircular hoop 72. Thus, when it is necessary to fix the water gun, it can be fixed between the movable semicircular hoop 72 and the fixed semicircular hoop 71.

[0034] The other end of the horizontal bar 1 is threaded with a limit bolt 9, thus forming a limit structure, which facilitates the formation of a safety fulcrum and provides limit protection for firefighters working at height.

[0035] To prevent situations where there are no suitable clamping and fixing points in the fire scene, the top and bottom of the first sliding frame 3 are formed with oppositely arranged fixing holes 31. Furthermore, the fixing holes 31 are threaded holes, and a threaded rod is fixed to the top of the support, so that the threaded hole and the threaded rod can be quickly fixed by rotation.

[0036] Supports include, but are not limited to, tripod supports.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the essence and scope of the technical solution of this utility model.
