Description

Technical Field

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

[0002] In fire fighting and firefighting operations in hazardous materials warehouses, traditional fire extinguishing spray devices often require firefighters to operate them in dangerous environments for extended periods, continuously spraying water from handheld nozzles to extinguish fires or cool them down, in order to ensure the stability of the nozzles and the accuracy of the spray direction. This poses a serious threat to the personal safety of firefighters.

[0003] Referring to patent document CN118304602A, a fire extinguishing spray device is proposed. This device solves the problem of fixing the fire hose by using an angle adjustment component and a fixing block. However, in hazardous operating environments, the challenge of on-site operation by personnel still needs to be addressed. Furthermore, while the device is equipped with wheels for easy movement, the recoil force generated by the water hose makes it difficult to keep the wheels stationary, and the device is prone to movement during spraying.

[0004] In existing technologies, there are single-pole supports, but these supports lack sufficient lateral support and are prone to tipping over when spraying water. There are also supports that use tripods, but these supports cannot be properly fixed to the ground and rely solely on their own weight to hold the water gun in place, making them unstable when spraying water. Summary of the Invention

[0044] like Figure 1 , 2As shown, the fire hose bracket includes a pole assembly, an adjustable mounting base 1, a tripod support assembly, and a snap-fit ​​assembly 20. The pole assembly includes a fixed pole 4 and a telescopic pole 2 that are relatively telescopic and rotatable. A pole locking nut 3 is fitted onto the telescopic pole 2 and locked to the fixed pole 4 to achieve a fixed and limited position. Specifically, the telescopic pole 2 extends from top to bottom into the fixed pole 4, and the two are fitted with a clearance fit. The relative position of the telescopic pole 2 and the fixed pole 4 is adjusted to regulate the overall height of the pole assembly, and then locked by the pole locking nut 3. The pole locking nut 3 can be locked in such a way that it has an internal thread, the upper end of the fixed pole 4 has an external thread, and the pole locking nut 3 is fitted onto the outside of the telescopic pole 2 and locked to the fixed pole 4 via a threaded connection. When the pole locking nut 3 is tightened onto the fixed pole 4, it applies radial pressure to the telescopic pole 2, such as through a conical surface, rubber pad, or friction plate, ensuring tight contact between the telescopic pole 2 and its outer wall, and connecting it threadedly to the fixed pole 4, preventing relative rotation and extension / retraction between the telescopic pole 2 and the fixed pole 4. When the pole locking nut 3 is not tightened, the telescopic pole 2 is in its lowest position and can rotate relative to the fixed pole 4, allowing for remote adjustment of the fire hose's horizontal angle by moving the hose connected to the fire hose.

[0045] like Figure 4As shown, the adjustable mounting base 1 is located at the top of the telescopic rod 2 and is used to mount the fire hose and adjust its pitch angle. The adjustable mounting base 1 includes a base 11, a U-shaped mounting plate 14, and a latch 15. The base 11 is fixed to the top of the telescopic rod 2. Specifically, a connector is provided below the base 11 and inserted into the telescopic rod 2, and is locked with screws. The U-shaped mounting plate 14 is used to support the fire hose, one end of which is hinged to the upper part of the base 11, and the other end is connected to the lower part of the base 11 through an arc-shaped adjusting plate 18 to adjust the pitch angle of the U-shaped mounting plate 14 and the fire hose. Specifically, the base 11 is a symmetrical triangular base, and one end of the U-shaped mounting plate 14 is hinged to the upper corner of the two triangles of the symmetrical triangular base through an axis, and can be locked by a second locking screw 13. One end of the arc-shaped adjusting plate 18 is fixedly connected to the other end of the U-shaped mounting plate 14. The other end of the arc-shaped adjusting plate 18 has an arc-shaped groove, and another shaft passes through the arc-shaped groove and connects to the lower corner of one side of the triangle of the symmetrical triangular base. The U-shaped mounting plate 14 can rotate along the arc-shaped groove with the axis as the center to adjust the pitch angle, and can be locked by the first locking screw 12. The arc-shaped adjusting plate 18 can also be symmetrically connected to the two triangles of the symmetrical triangular base. Generally, after adjusting the pitch angle, first lock the first locking screw 12, and then lock the second locking screw 13 to complete the double locking and make the structure stable. The latch 12 is provided on the U-shaped mounting plate 14 and is used to fix the fire hose to the U-shaped mounting plate 14. Specifically, the latch 15 includes a hook 16 and a clamping part 17, and the hook 16 is provided on one side of the U-shaped mounting plate 14. The clamping member 17 is arc-shaped to fit the shape of the fire hose reel. One end is hinged to the other side of the U-shaped mounting plate 14, and the other end overlaps with the hook 16. It also has a locking member to lock the hook 16 and the clamping member 17 together. This is used to cooperate with the U-shaped support structure of the U-shaped mounting plate 14 to securely fix the fire hose reel. The latch 15 is not limited to... Figure 4 Any structure shown that can achieve the function of fixing the fire hose is acceptable.

[0046] like Figure 1 , 2 As shown, the tripod support assembly includes a movable tripod base 5, a tripod locking nut 6, and a tripod rod 7. The movable tripod base 5 is slidably sleeved on the fixed upright 4. One end of the tripod rod 7 is hinged to the movable tripod base 5, and the other end is used to support the ground. The movable tripod base 5 is threadedly connected to the movable tripod base 5 via the tripod locking nut 6, thus locking the position of the movable tripod base 5 on the fixed upright 4. Further, the tripod locking nut 6 is confined to the middle of the fixed upright 4 by a retaining ring, and the movable tripod base 5 is located above the tripod locking nut 6. Specifically, the fixed upright 4 has a groove in the middle, and the retaining ring is disposed within the groove and protrudes from the groove. The tripod locking nut 6 is sleeved on the retaining ring, so that the retaining ring at least restricts the upward movement of the tripod locking nut 6. Figure 9As shown, the bottom of the tripod locking nut 6 has a protrusion, which restricts the upward movement of the tripod locking nut 6 by the retaining ring. Alternatively, a corresponding groove can be provided on the inner wall of the tripod locking nut 6, with the retaining ring placed between the groove of the tripod locking nut 6 and the groove of the fixed pole 4, restricting the vertical movement of the tripod locking nut 6 to rotation only. The movable tripod 5 has an external thread, and the tripod locking nut 6 has an internal thread. The external thread of the movable tripod 5 and the internal thread of the tripod locking nut 6 can be threadedly connected. When the tripod support assembly needs to be unfolded, the movable tripod 5 moves downward above the tripod locking nut 6 and connects with it threadedly. The movable tripod 5 can be held appropriately, and the tripod locking nut 6 can be rotated to move the movable tripod 5 downward along the fixed pole 4. When the tripod support assembly needs to be folded, the tripod locking nut 6 is rotated in the opposite direction to move the movable tripod 5 upward along the fixed pole 4, disengaging from the tripod locking nut 6.

[0047] The tripod assembly also includes a support member 8 and a fixed tripod base 10. The fixed tripod base 10 is fixedly sleeved on the lower part of the fixed upright 4. One end of the support member 8 is hinged to the fixed tripod base 10, and the other end is hinged to the middle of the tripod support rod 7. The fixed tripod base 10 also ensures that the movable tripod base 5 can only move up and down along the fixed upright 4 and cannot rotate. When the tripod support locking nut 6 locks the position of the movable tripod base 5, the fixed upright 4, the tripod support rod 7, and the support member 8 form a stable triangular structure, and the tripod support rod 7 can be stably supported on the bottom surface. Specifically, the tripod support rod 7 can be provided with three support rods around the circumference of the movable tripod base 5. The support member 8 can be provided with three support rods around the circumference of the fixed tripod base 10, which are respectively connected to the three support rods of the tripod support rod 7. The lower end of the tripod support rod 7 is provided with a movable foot 9, and the bottom surface of the movable foot 9 can be provided with anti-slip texture. The support member 8 has a U-shaped structure, and the two ends of the U-shaped structure are hinged to the two sides of the tripod support rod 7, such as... Figure 3 As shown, when the fire hose bracket is not in use, the tripod 7 can be folded up and neatly hidden inside the U-shaped structure, thereby reducing storage space.

[0048] like Figures 5 to 8As shown, the latching assembly 20 is disposed at the bottom of the fixed pole 4 and is used to lock with the T-shaped post 114 pre-embedded in the ground. The latching assembly 20 includes a latching body 111, a latching outer ring 112, and a spring pin 113. The latching body 111 is connected to the bottom of the fixed pole 4 and has a cavity 115 for accommodating the upper part of the T-shaped post 114. An opening 116 is provided on its side for the upper part of the T-shaped post 114 to enter the cavity 115. The latching outer ring 112 is movably sleeved on the latching body 111 and has a movable opening 117 on its side that cooperates with the opening 116 and can be staggered vertically. The spring pin 113 is disposed between the latching body 111 and the latching outer ring 112 and is engaged with the upper positioning hole 118 or the lower positioning hole 119 on the inner side of the latching outer ring 112 to realize the vertical staggering of the opening 116 and the movable opening 117. T-shaped column 114 is a T-shaped structure pre-embedded in a groove set in the ground. Its upper cross-sectional dimensions are larger than its lower dimensions, while the height and diameter of the upper part are slightly smaller than the height and diameter of the cavity. Furthermore, the top surface of T-shaped column 114 does not exceed the ground level. Specifically, as... Figure 8 As shown, the buckle body 111 includes a connecting portion 120 connected to the bottom of the fixed upright 4, an extension portion 121 extending outward from the lower end of the connecting portion 120, a receiving portion 122 extending downward from the extension portion 121, and a limiting portion 123 extending inward from the lower end of the receiving portion 122 to a diameter equivalent to the lower part of the T-shaped post 114. The extension portion 121, the receiving portion 122, and the limiting portion 123 form a cavity 115 that can accommodate the upper part of the T-shaped post 114. An opening 116 is formed on the side of the receiving portion 122 and the limiting portion 123. The buckle outer ring 112 includes a snap-fit ​​portion 124 fitted onto the receiving portion 122, and a movable opening 116 is formed on the side of the snap-fit ​​portion 124. A spring pin 113 is provided in the receiving portion 122, and an upper positioning hole 118 and a lower positioning hole 119 are provided inside the snap-fit ​​portion 124. Two pairs of upper positioning holes 118 and lower positioning holes 119 are symmetrically arranged on both inner sides of the latching part 124, and spring pins 113 are arranged at corresponding positions in the receiving part 122 to make the latching more stable. When the outer ring 112 of the latch is in the upper position and the spring pin 113 is engaged with the lower positioning hole 119, the movable opening 117 and the opening 116 coincide, allowing the upper part of the T-shaped post 114 to enter the cavity 115, and the latching assembly 20 is in the unlocked state. When the outer ring 112 of the latch is in the lower position and the spring pin 113 is engaged with the upper positioning hole 118, the movable opening 117 is lower than the opening 116, the upper part of the T-shaped post 114 is limited in the cavity 115, and the latching assembly 20 is in the locked state.
