When using this device, the adjustment sleeve and movable adjustment rod in the multi-angle adjustment device cooperate to allow the front and rear adjustment tubes to rotate at any angle. Therefore, when using the fire hose, the spray angle of the water flow can be changed by rotating the rear adjustment tube. This device is applicable to firefighting and disaster relief in any scenario, enabling faster and more effective fire suppression and reducing losses caused by fires.

[0004] When workers need to extinguish a fire, they connect the fire hose to the water supply pipe so that they can use the fire hose to extinguish the fire. However, existing fire hoses need to be tilted to adjust the angle during use. Because the fire hose is relatively long, workers need a lot of space to adjust it, which causes inconvenience when extinguishing a fire. Summary of the Invention

[0005] The purpose of this utility model is to solve the problem of inconvenience for workers when extinguishing fires in the existing technology, and to propose a fire hose with multi-angle adjustment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a fire hose with multi-angle adjustment, including a nozzle, a connecting handle on one side of the nozzle, an adjustment device on the surface of the connecting handle, the adjustment device including a rotating ring, the rotating ring being placed on one end of the connecting handle, a rotating groove being formed on the inner side of the rotating ring, a limiting plate being fixedly connected to the surface of the connecting handle, the rotating groove being rotatably connected to the surface of the limiting plate, a support block being fixedly connected to the surface of the rotating ring, a connecting ring being fixedly connected to one end of the nozzle, the connecting ring being rotatably connected to the surface of the support block, a connecting hose being rotatably connected between the nozzle and the connecting handle, a limiting component being provided on the surface of the rotating ring, the limiting component consisting of a positioning rod and a positioning hole, a positioning hole being formed on the surface of the limiting plate, the positioning hole being located inside the rotating groove, the positioning hole being able to cooperate with the limiting plate to achieve the purpose of accommodating the positioning rod.

[0008] Preferably, the surface of the rotating ring is provided with a positioning device, the positioning device including an adjusting ring, the adjusting ring being placed on the surface of the rotating ring, the surface of the adjusting ring being fixedly connected to an insert plate, the insert plate being slidably connected to the inside of the support block, and the adjusting ring being able to cooperate with the insert plate to achieve the purpose of supporting the sliding of the insert plate.

[0009] Preferably, the rotating shaft of the connecting ring is fixedly connected to a rotating block, the surface of the rotating block is provided with a storage groove, the insert plate is inserted into the inside of the storage groove, the rotating block can cooperate with the connecting ring to achieve the purpose of supporting the rotating block, and the insert plate can cooperate with the rotating block and the storage groove to achieve the purpose of restricting the rotation of the rotating block.

[0010] Preferably, an extension ring is fixedly connected to one side of the rotating ring, and a return spring is fixedly connected between the adjusting ring and the extension ring. The return spring is located on both sides of the connecting grip, and the extension ring can cooperate with the adjusting ring and the return spring to achieve the purpose of pushing the adjusting ring to return to its original position.

[0011] Preferably, a magnetic block is fixedly connected to one side of the adjusting ring. The magnetic block is located on one side of the extension ring and can cooperate with the adjusting ring to restrict the sliding of the adjusting ring.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting an adjustment device, when the worker needs to adjust the spray angle of the fire hose, the worker adjusts the positioning device, which releases the limiting position on the connecting ring. The worker pulls or pushes the nozzle, causing the nozzle to drive the connecting ring, bending the connecting hose. The support block guides the connecting ring to rotate, causing the nozzle to tilt. When the nozzle tilts to a certain angle, the worker adjusts the positioning device, which then restricts the connecting ring. The worker rotates the positioning rod as needed, causing the positioning rod to retract and disengage from the positioning hole. The worker then rotates the nozzle, causing the nozzle to drive the connecting ring, which in turn drives the support block. The support block drives the rotating ring, which is guided by the limiting plate and rotates. When the nozzle rotates to the specified angle, the nozzle's orientation changes. The worker then rotates the positioning rod, which extends and inserts into the positioning hole, fixing the nozzle's orientation. By setting an adjustment device, the worker can effectively and conveniently adjust the spray angle of the fire hose, avoiding the need for a large space when adjusting the fire hose, thus reducing inconvenience for the worker during firefighting.

[0013] In this invention, by setting a positioning device, when the worker needs to restrict the rotation of the nozzle, the worker pulls the adjusting ring backward. The adjusting ring drives the insert plate, which retracts and disengages from the receiving groove. The adjusting ring pushes the magnetic block to contact the surface of the extension ring. The magnetic block restricts the sliding of the adjusting ring through magnetic force. The worker adjusts the angle of the nozzle. After the nozzle angle is adjusted, the worker pushes the adjusting ring forward. The adjusting ring is pushed by the return spring, and the adjusting ring drives the magnetic block to disengage from the extension ring. The adjusting ring pushes the insert plate, which inserts into the receiving groove of the rotating block. By setting a positioning device, the rotation of the nozzle can be effectively restricted, avoiding the need for the worker to keep manually restricting the nozzle after adjusting the angle, thereby reducing the worker's workload.

[0019] Specifically, the surface of the limiting plate 36 is provided with a positioning hole 37, which is located inside the rotating groove 35. The positioning hole 37 can cooperate with the limiting plate 36 to achieve the purpose of storing the positioning rod 32.

[0020] Specifically, the rotating ring 31 has an internal threaded connection to a positioning rod 32, which is inserted into the positioning hole 37.

[0021] In this embodiment, the positioning rod 32 can cooperate with the rotating ring 31 to guide the positioning rod 32.

[0022] In this embodiment: a positioning device 4 is provided on the surface of the rotating ring 31. The positioning device 4 includes an adjusting ring 45. The adjusting ring 45 is placed on the surface of the rotating ring 31. An insert plate 43 is fixedly connected to the surface of the adjusting ring 45. The insert plate 43 is slidably connected to the inside of the support block 34. The adjusting ring 45 can cooperate with the insert plate 43 to achieve the purpose of supporting the sliding of the insert plate 43.

[0023] Specifically, the rotating shaft of the connecting ring 33 is fixedly connected to the rotating block 41, and the surface of the rotating block 41 is provided with a storage groove 42, and the insert plate 43 is inserted into the inside of the storage groove 42.

[0024] In this embodiment: the rotating block 41 can cooperate with the connecting ring 33 to support the rotating block 41, and the insert plate 43 can cooperate with the rotating block 41 and the storage groove 42 to restrict the rotation of the rotating block 41.

[0026] Specifically, a magnetic block 46 is fixedly connected to one side of the adjusting ring 45, and the magnetic block 46 is located on one side of the extension ring 47.

[0027] In this embodiment, the magnetic block 46 can cooperate with the adjusting ring 45 to restrict the sliding of the adjusting ring 45.

[0028] Working Principle: By setting the adjustment device 3, when the worker needs to adjust the spray angle of the fire hose, the worker adjusts the positioning device 4. The positioning device 4 releases the limit on the connecting ring 33. The worker pulls or pushes the nozzle 1, which drives the connecting ring 33, causing the connecting hose 38 to bend. The support block 34 guides the connecting ring 33 to rotate, and the nozzle 1 tilts. When the nozzle 1 tilts to a certain angle, the worker adjusts the positioning device 4, which restricts the connecting ring 33. The worker rotates the positioning rod 32 as needed. The positioning rod 32 retracts and disengages from the positioning hole 37. The worker rotates the nozzle 1, which drives the connecting ring 33. The connecting ring 33 drives the support block 34, which drives the rotating ring 31. The rotating ring 31 is guided by the limiting disc 36 and rotates. When the nozzle 1 rotates to the specified angle, the orientation of the nozzle 1 changes. The worker rotates the positioning rod 32, which extends and inserts into the positioning hole 37, fixing the orientation of the nozzle 1. By setting the adjustment device 3, the worker can effectively facilitate the adjustment of the nozzle. Adjusting the spray angle of the fire hose eliminates the need for workers to have a large space when adjusting the hose, thus reducing inconvenience during firefighting. Furthermore, by incorporating the positioning device 4, when workers need to restrict the rotation of the nozzle 1, they pull the adjusting ring 45 backward. The adjusting ring 45 drives the insert plate 43, which retracts and disengages from the receiving groove 42. The adjusting ring 45 then pushes the magnetic block 46 into contact with the surface of the extension ring 47. The magnetic block 46 uses magnetic force to restrict the sliding of the adjusting ring 45. After adjusting the nozzle 1 angle, the worker pushes the adjusting ring 45 forward. The adjusting ring 45, pushed by the return spring 44, causes the magnetic block 46 to disengage from the extension ring 47. The adjusting ring 45 then pushes the insert plate 43, which inserts into the receiving groove 42 of the rotating block 41. By incorporating the positioning device 4, the rotation of the nozzle 1 can be effectively restricted, avoiding the need for workers to continuously restrain the nozzle 1 by hand after adjusting its angle, thus reducing the workload of the workers.
