Description

Technical Field

[0001] This utility model relates to the field of fire hose anti-twisting technology, and in particular to a fire hose anti-twisting structure. Background Technology

[0002] Fire hoses are flexible hoses used to deliver water to fire scenes. They are mainly used to transport water to the fire scene and extinguish flames and reduce the temperature of burning materials through water spraying and cooling, thereby controlling the fire and extinguishing it. If fire hoses are coiled too tightly or stored in poor environments (such as dampness or high temperature), they may twist and deform during use. Twisting of fire hoses during use will affect the delivery of fire-fighting water.

[0003] Currently, when performing anti-twisting operations on fire hoses, the user usually rolls the fire hose into a double-roll type. This double-roll type of hose is less prone to twisting when unrolled. However, manually winding the anti-twisting hose is cumbersome and laborious when winding long hoses. Furthermore, fire hoses are prone to twisting when unwinding due to friction and aging caused by repeated use. Therefore, we propose an anti-twisting structure for fire hoses. Utility Model Content

[0004] The main objective of this invention is to provide an anti-twisting structure for fire hoses. A winding mechanism is installed at the base plate, using a sleeve and a pressure plate to clamp the folded fire hose. The mechanism then rotates and winds the hose around the base plate using a smooth rod. This double-wrap winding method prevents the fire hose from twisting during use, significantly improving the ease of winding. Even if the fire hose twists due to friction, it can be manually straightened by holding the sleeve and pressure plate, effectively preventing twisting and solving the problems in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A fire hose anti-twisting structure includes a base plate and a hose reeling mechanism. The hose reeling mechanism includes a rotating column, a fixed column, an L-shaped support plate, a smooth rod bolt shaft, a sleeve, a pressure plate, and a handle. Branch pipes are symmetrically welded to the surface of the base plate, and a rotating column is screwed onto the top of each branch pipe. A fixed column is inserted into the rotating column and fixed to the bottom of the vertical plate of the L-shaped support plate. A U-shaped groove for inserting the smooth rod bolt shaft is formed on the surface of the vertical plate of the L-shaped support plate. A flange nut is screwed onto the smooth rod bolt shaft where it passes through the bolt body of the L-shaped support plate. A sleeve is fitted around the smooth rod bolt shaft between the two sets of plates of the L-shaped support plate. A bent plate at one end of the pressure plate is fixed to the outside of the sleeve. A handle is inserted into the outer end face of the threaded bolt of the smooth rod bolt shaft. A guide rod is fixed to the long plate surface of the L-shaped support plate away from the U-shaped groove, and an upper guide rod is fitted onto the surface of the L-shaped support plate above the guide rod.

[0007] Furthermore, a hexagonal block is fixed to the upper end of the rotating column, and an insertion hole for inserting the insertion post is provided at the upper end of the rotating column. The outer side of the insertion post has protruding ribs, and the inner wall of the insertion hole has recessed grooves.

[0008] By adopting the above technical solution, a wrench can be used to rotate the hexagonal block of the rotating column, thereby screwing the rotating column into the branch pipe, while the insertion pin can be firmly inserted into the insertion hole for connection.

[0009] Furthermore, the U-shaped rotating groove has three protruding hemispherical fulcrums on its arc-shaped groove wall, and a smooth rod bolt is supported at the hemispherical fulcrum of the U-shaped rotating groove.

[0010] By adopting the above technical solution, the arc-shaped groove wall of the U-shaped rotating groove can support the smooth rotation of the smooth rod bolt shaft with a hemispherical fulcrum.

[0011] Furthermore, the outer end face of the threaded bolt of the optical rod is provided with a side fixing hole for inserting the side fixing rod, and the inner wall of the side fixing hole is recessed with an inner groove. The rod body of the side fixing rod has a protruding rib, and one end of the rod body of the side fixing rod is welded to the surface of the handle plate of the rotating handle.

[0012] By adopting the above technical solution, the rotating handle can be inserted and connected to the side fixing hole of the smooth rod bolt shaft by the side fixing rod, and then the rotating handle can rotate with the bushing through the side fixing rod.

[0013] Furthermore, a side column groove is provided on the surface of the L-shaped support plate above the guide rod, and a side column plate is installed in the side column groove. An upper guide rod is welded to the rounded surface of the side column plate.

[0014] By adopting the above technical solution, the guide rod and side column plate can be positioned and clamped at the side column groove of the L-shaped support plate.

[0015] Furthermore, the inner wall of the sleeve is symmetrically provided with semi-circular grooves, and semi-circular ribs protruding from the outer surface of the smooth rod bolt are inserted into the semi-circular grooves.

[0016] By adopting the above technical solution, when the bushing is sleeved on the outside of the smooth rod bolt shaft, the smooth rod bolt shaft can be clamped and connected at the semi-circular groove of the bushing with the help of the semi-circular rib.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This utility model installs a winding mechanism at the base plate. The winding mechanism uses a sleeve sleeve and a pressure plate to clamp the folded fire hose, and uses a smooth rod bolt at the L-shaped support plate to rotate and wind the hose. By using a double-winding method, the fire hose is folded in half and then wound up. The fire hose is wound into a double-winding body and is not easily twisted when thrown out for use, which effectively avoids twisting of the fire hose during use and effectively improves the convenience of winding the fire hose.

[0019] Even if the fire hose twists due to friction during use, it can be manually straightened by holding the sleeve and pressure plate to prevent twisting. Attached Figure Description

[0025] like Figure 1-3As shown, a fire hose anti-twisting structure includes a base plate 1 and a hose reel mechanism 3. The hose reel mechanism 3 includes a rotating column 4, a fixed insertion column 6, an L-shaped support plate 7, a smooth rod bolt shaft 9, a sleeve sleeve 11, a pressure plate 12, and a rotating handle 15. Branch pipes 2 are symmetrically welded to the surface of the base plate 1, and a rotating column 4 is screwed onto the top of the branch pipe 2. The fixed insertion column 6 is inserted into the rotating column 4 and fixed to the bottom of the vertical plate of the L-shaped support plate 7. The surface of the vertical plate of the L-shaped support plate 7 has openings for inserting smooth rod bolts. The U-shaped groove 8 of shaft 9, the flange nut 10 is screwed into the bolt body of the smooth rod bolt 9 through the L-shaped support plate 7, and the smooth rod bolt 9 between the two sets of plates of the L-shaped support plate 7 is fitted with a sleeve sleeve 11. One end of the pressure plate 12 is fixed to the outside of the sleeve sleeve 11. A rotating handle 15 is inserted into the outer end face of the threaded bolt of the smooth rod bolt 9. A guide rod 19 is fixed to the long plate surface of the L-shaped support plate 7 away from the U-shaped groove 8, and an upper guide rod 18 is fitted onto the surface of the L-shaped support plate 7 above the guide rod 19.

[0026] Among them, a hexagonal block is fixed on the upper end of the rotating column 4, and an insertion hole 5 for inserting the insertion post 6 is opened at the upper end of the rotating column 4. The outer side of the insertion post 6 has protruding ribs, and the inner groove wall of the insertion hole 5 is recessed with a groove.

[0027] By adopting the above technical solution, a wrench can be used to rotate the hexagonal block of the rotating column 4, thereby screwing the rotating column 4 into the branch pipe 2, while the insertion column 6 can be firmly inserted into the insertion hole 5 for connection.

[0028] Among them, the U-shaped rotating groove 8 has three protruding hemispherical support points inside the arc-shaped groove wall, and the smooth rod bolt shaft 9 is supported at the hemispherical support point of the U-shaped rotating groove 8.

[0029] By adopting the above technical solution, the arc-shaped groove wall of the U-shaped rotating groove 8 can support the smooth rotation of the smooth rod bolt shaft 9 with a hemispherical fulcrum.

[0030] The threaded bolt body of the optical rod 9 has a side fixing hole 13 for inserting the side fixing rod 14 on its outer end face, and the inner wall of the side fixing hole 13 is recessed with an inner groove. The rod body of the side fixing rod 14 has a protruding rib, and one end of the rod body of the side fixing rod 14 is welded to the surface of the handle plate of the rotating handle 15.

[0031] By adopting the above technical solution, the rotating handle 15 can be inserted and connected to the side fixing hole 13 of the smooth rod bolt shaft 9 via the side fixing rod 14, and then the rotating handle 15 can rotate with the bushing 11 via the side fixing rod 14.

[0032] Among them, the L-shaped support plate 7 above the guide rod 19 has a side column groove 16, and a side column plate 17 is installed in the side column groove 16. The upper guide rod 18 is welded to the round head plate surface of the side column plate 17.

[0033] By adopting the above technical solution, the guide rod 19 and the side column plate 17 can be positioned and clamped at the side column groove 16 of the L-shaped support plate 7.

[0034] The inner wall of the sleeve 11 is symmetrically provided with semi-circular grooves, and a semi-circular rib protruding from the outer surface of the smooth rod bolt 9 is inserted into the semi-circular groove.

[0035] By adopting the above technical solution, when the sleeve 11 is sleeved on the outside of the smooth rod bolt 9, the smooth rod bolt 9 can be connected by means of the semi-circular bar rib at the semi-circular groove of the sleeve 11.

[0036] It should be noted that this utility model is a fire hose anti-twisting structure. When the fire hose needs to be anti-twisted during winding, the hose body can be folded in half so that the two folded sections are of the same length. Then, the folded section is inserted between the pressure plate 12 and the sleeve 11. At this time, the smooth rod 9 can be inserted through the sleeve 11. The smooth rod 9 can then be inserted into the U-shaped groove 8 of the L-shaped support plate 7, so that the sleeve 11 is positioned between the two sets of plates of the L-shaped support plate 7. Next, the smooth rod 9 can be threaded through the threaded bolt of the L-shaped support plate 7 and screwed onto the flange nut 10, ensuring that the smooth rod 9 can be restricted to rotate smoothly in the U-shaped groove 8. Then, the hose between the L-shaped support plates 7 can be placed on the surface of the guide rod 19. The upper guide rod 18 and the side column plate 17 can be clamped into the side column groove 16 of the L-shaped support plate 7 for clamping, so that the water hose is between the upper guide rod 18 and the support rod 19. Then, the rotating handle 15 can be inserted and connected to the side fixing hole 13 of the smooth rod bolt shaft 9 with the help of the side fixing rod 14. Then, the person winding the hose steps on the side plate surface of the base plate 1 and holds the rotating handle 15 to drive the smooth rod bolt shaft 9 to rotate with the sleeve sleeve 11. After the sleeve sleeve 11 rotates, it can wind up the fire hose until the fire hose is wound into a double-wound water hose body. The water hose wound into a double-wound water hose body is not easy to twist when it is thrown out for use. Even if the water hose body is twisted due to friction, the sleeve sleeve 11 and the pressure plate 12 can be manually held to straighten the water hose body and prevent the fire hose from twisting.
