Description

Technical Field

[0001] This utility model relates to the field of fire rescue technology, and in particular to a hose reel for fire rescue. Background Technology

[0002] When a fire breaks out, it is necessary to call the fire department immediately. Firefighters will use hoses connected to fire hydrants to spray water from the hydrants towards the fire. However, after the fire is extinguished, a hose reel is needed to retract the hose. The hose reel has some defects and shortcomings, specifically requiring improvement: 1. When the hose reel is working, a manual crank is required to retract the hose. However, the lower support of the CN214550823U hose is weak, causing it to wobble during use and making retraction difficult; 2. When retracting the hose, its position needs to be fixed to prevent it from shifting during retraction. Also, water may remain inside the hose, requiring it to be leveled and drained before retracting. Therefore, we propose a hose reel for fire rescue. Utility Model Content

[0003] The main objective of this invention is to provide a hose reel for fire rescue, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A hose reel for fire rescue includes a fixed plate. A rotating handle is movably connected to the middle of the left end of the fixed plate. Rubber strips are fixedly connected at equal intervals to the outer surface of the left side of the rotating handle. Positioning holes are opened at the front and rear of the left end of the fixed plate. A main reel is fixedly connected to the right end of the rotating handle. A rectangular plate is fixedly connected to the left side of the outer surface of the main reel. A secondary reel is fixedly connected to the lower right end of the rectangular plate. A support mechanism is fixedly connected to the middle of the left end of the fixed plate. A limit mechanism is fixedly connected to the left front end of the support mechanism.

[0006] Preferably, the support mechanism includes a connecting column, on which two sets of connecting rings are inserted and movably engaged. A limit plate is inserted and fixedly connected to the left side of the connecting column. Folded support legs are fixedly connected to the outer surfaces of both sets of connecting rings. Positioning rods are threaded and engaged on both sets of folded support legs. A turntable is fixedly connected to the left end of both sets of positioning rods.

[0007] By adopting the above technical solution, the two sets of folded support legs can be separated to form a stable triangular mechanism, which supports the upper structure and water hose, thereby improving stability.

[0008] Preferably, the connecting column is fixedly connected to the fixed plate, the two sets of connecting rings are located between the limiting plate and the fixed plate, and the upper end of the front folded support leg is fixedly connected to the limiting mechanism.

[0009] By adopting the above technical solution, the angle of the folded support leg can be fixed by inserting and engaging the positioning rod with the nearby positioning hole.

[0010] Preferably, the limiting mechanism includes two sets of rectangular frames, left and right. A threaded rod is movably disposed inside the left rectangular frame, and a second turntable is fixedly connected to the upper end of the threaded rod. A round rod is fixedly connected between the upper inner wall and the lower inner wall of the right rectangular frame. A limiting rod is threadedly inserted and snapped onto the threaded rod. A scraping plate is fixedly connected to the lower left and lower right ends of the limiting rod.

[0011] By adopting the above technical solution, the position of the hose can be limited by two sets of rectangular frames, preventing the hose from shifting when it is being wound up.

[0012] Preferably, the two sets of rectangular frames are fixedly connected to the front folded support legs, and the limiting rod passes through the two sets of rectangular frames.

[0013] By adopting the above technical solution, the height of the limiting rod can be adjusted by passing the threaded rod through the limiting rod.

[0014] Preferably, the limiting rod and the round rod are interlocked and engaged, and both sets of the scraping plates are inclined.

[0015] By adopting the above technical solution, two sets of scraping plates are set at an angle, forming a V-shape, which can flatten the water hose and drain the water inside.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By setting up a support mechanism, the two sets of folded support legs can rotate outward to form a stable triangular structure, which supports the upper structure and the water hose. The positioning rod on the folded support leg engages with the positioning hole to fix the angle of the two sets of folded support legs, which helps to reduce shaking when winding the water hose.

[0018] 2. By setting a limiting mechanism, the two sets of rectangular frames on the limiting mechanism can facilitate the left and right displacement of the water hose when it is being wound up. At the same time, the scraping plate at the bottom can flatten the water hose and press it down to discharge the water from the water hose. Attached Figure Description

[0027] Please see Figure 1-4 This utility model provides a technical solution:

[0028] A hose reel for fire rescue includes a fixed plate 1. A rotating handle 2 is movably connected to the middle of the left end of the fixed plate 1. Rubber strips 3 are fixedly connected at equal intervals to the outer surface of the left side of the rotating handle 2. Positioning holes 4 are opened at the front and rear of the left end of the fixed plate 1. A main reel 5 is fixedly connected to the right end of the rotating handle 2. A rectangular plate 6 is fixedly connected to the left side of the outer surface of the main reel 5. A secondary reel 7 is fixedly connected to the lower right end of the rectangular plate 6. A support mechanism 8 is fixedly connected to the middle of the left end of the fixed plate 1. A limit mechanism 9 is fixedly connected to the left front end of the support mechanism 8.

[0029] In this embodiment, the support mechanism 8 includes a connecting column 10, on which two sets of connecting rings 11 are inserted and movably engaged. A limiting plate 12 is inserted and fixedly connected to the left side of the connecting column 10. Folded support legs 13 are fixedly connected to the outer surfaces of the two sets of connecting rings 11. Positioning rods 14 are threaded and engaged on the two sets of folded support legs 13. A turntable 15 is fixedly connected to the left end of the two sets of positioning rods 14. The connecting column 10 is fixedly connected to the fixed plate 1. The two sets of connecting rings 11 are located between the limiting plate 12 and the fixed plate 1. A limiting mechanism 9 is fixedly connected to the upper end of the folded support legs 13 at the front.

[0030] Through the above scheme: under the action of the positioning rod 14 and the positioning hole 4, the angle between the two sets of folded support legs 13 can be fixed, and the two sets of folded support legs 13 form a triangular support space with the ground, which supports the upper structure and the water hose and reduces shaking when winding the water hose.

[0031] In this embodiment, the limiting mechanism 9 includes two sets of rectangular frames 16, one on the left and one on the right. A threaded rod 17 is movably disposed inside the left rectangular frame 16. A second turntable 18 is fixedly connected to the upper end of the threaded rod 17. A round rod 19 is fixedly connected between the upper inner wall and the lower inner wall of the right rectangular frame 16. A limiting rod 20 is threadedly inserted and snapped onto the threaded rod 17. A scraping plate 21 is fixedly connected to the lower left and lower right ends of the limiting rod 20. The two sets of rectangular frames 16 are fixedly connected to the front folded support leg 13. The limiting rod 20 passes through the two sets of rectangular frames 16. The limiting rod 20 and the round rod 19 are inserted and snapped together. Both sets of scraping plates 21 are inclined.

[0032] Through the above scheme: the two sets of rectangular frames 16 on the limiting mechanism 9 can prevent the water hose from shifting left and right during winding, while the two sets of scraping plates 21 at the bottom of the limiting rod 20 can flatten the passing water hose and drain the water in the water hose, making it easier for the water hose to be wound up.

[0033] It should be noted that this utility model is a hose reel for fire rescue. During use, after the fire is extinguished, the hose needs to be reeled in. First, rotate the two sets of turntables 15 and positioning rods 14, rotating the two sets of folded support legs 13 outwards. Then, rotate the positioning rods 14 in the opposite direction, engaging with the adjacent positioning holes 4 to fix the angle between the two sets of folded support legs 13. The two sets of folded support legs 13 form a triangular support structure with the ground, supporting the upper structure and the hose, reducing swaying during use. Shake the hose and pass it through the middle of the limiting rod 20 and the front folded support leg 13. Rotate the second turntable 18 and the threaded rod 17 so that the scraping plate 21 at the lower end of the limiting rod 20 contacts the surface of the hose. Then wrap one end of the hose that has passed through the limiting rod 20 around the main winding rod 5 and then around the auxiliary winding rod 7. After turning the rotating handle 2, the main winding rod 5 will rotate to wind up the hose. The hose is smoothed by the scraping plate 21, which makes it easier to wind up and also drains the residual water inside. After one section of hose is wound up, move the hose roll to the right to release it.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
