Description

Technical Field

[0002] Fire hoses are water-shooting tools for firefighting. When connected to a hose, they can spray dense and substantial water. Usually, during the spraying process, the operator moves the hose up, down, left, and right to adjust the spraying direction to extinguish the fire.

The support seat cooperates with the support frame, and the support seat cooperates with the support plate, so that the spray angle of the fire hose can be accurately and flexibly adjusted up, down, left and right, thereby improving the fire extinguishing efficiency.

[0025] In actual use, the pedal 23 is stepped on with the foot, and the pedal 23 moves downward through the movable rod 22 and the movable hole 21, and the spring stretches at the same time. When the pedal 23 contacts the ground, the friction between the bottom of the pedal 23 and the ground increases, so that the support foot 1 and the ground will not slide easily, thereby making the fire hose fixing device more stable. At the same time, under the action of the first spring 24, when the pedal 23 is not under force, the pedal 23 automatically returns to the initial position through the contraction force of the first spring 24, which improves the convenience of using the pedal 23. By using the body to contact the support frame 53, the recoil force of the water gun spraying water is transmitted to the support frame 53 through the support plate 5 and the support rod 52.

One end of the rotating shaft 61 passes through the rotating hole 621 and is fixedly connected to the inside of the rotating sleeve 623; the connecting shaft 631 rotates to drive the rotating sleeve 623 to rotate in the rotating groove 622, so that the connecting shaft 631 can rotate stably without being separated from the rotating hole 621.

[0029] refer to Figure 3 The clamping assembly 8 includes a second screw rod 81, a second screw hole 82 and a clamping assembly 83. The second screw hole 82 is opened on one side of the mounting block 7. The second screw rod 81 is threadedly connected to the inside of the second screw hole 82. The clamping assembly 83 is movably installed on one side of the clamping block 72. One end of the clamping assembly 83 is fixedly connected to the end of the second screw rod 81. When the second screw rod 81 is rotated, the second screw rod 81 is displaced under the action of the second screw hole 82 to drive the clamping block 72 to move, so that the clamping block 72 can be conveniently clamped.

[0030] refer to Figure 3 The locking assembly 83 includes a locking hole 831, a locking groove 832 and a locking ring 833. The locking hole 831 is provided on one side of the clamping block 72, the locking groove 832 is provided inside the locking hole 831, the locking groove 832 and the locking hole 831 are communicated with each other, the locking ring 833 is rotatably connected inside the locking groove 832, one end of the second screw rod 81 passes through the locking hole 831 and is fixedly connected inside the locking ring 833; the rotation of the second screw rod 81 drives the locking ring 833 to rotate in the locking groove 832, so that the second screw rod 81 will not be separated from the clamping block 72, and the clamping block 72 will not rotate with the rotation of the second screw rod 81.

[0031] refer to Figure 5 The connecting assembly 63 includes a connecting shaft 631, a second connecting hole 632 and a connecting block 633. The two ends of the connecting shaft 631 are respectively fixedly connected to the opposite sides inside the fixing frame 6. The second connecting hole 632 is opened on one side of the connecting block 633. The connecting block 633 is rotatably connected to the outer wall of the connecting shaft 631 through the second connecting hole 632; the connecting block 633 is rotated on the outer wall of the connecting shaft 631 through the second connecting hole 632, so that the mounting block 7 can conveniently adjust the vertical angle.

[0032] Principle and advantages of use: Place the fire hose gun inside the through slot 71 of the mounting block 7, adjust the clamping assembly 8 to drive the clamping block 72 to clamp the hose gun, rotate the second screw hole 82, and under the action of the second screw hole 82, the screw pushes the clamping block 72 to clamp, and at the same time, the second screw 81 passes through the clamping hole 831 and the clamping slot 832 of the clamping assembly 83, and the rotation of the second screw 81 drives the clamping ring 833 to rotate, so that the clamping block 72 slides stably without rotating, and the pedal 23 is stepped on by the foot, and the pedal 23 moves to the movable hole 21 on the movable rod 22 and the cross bar 2. When the pedal 23 contacts the ground, the friction between the support leg 1 and the ground increases, thereby improving the stability of the support leg 1. Under the action of the first spring 24, when the pedal 23 is not under force, the pedal 23 can automatically return to the initial position, so that the body contacts the support frame 53. When the fire hose is started, the recoil of the hose is transmitted to the support rod 52 through the support plate 5, the buffer groove 51 and the support rod 52. Under the restriction of the body, the support plate 5 can be stable and immovable. The recoil of the hose causes the second spring 54 to limit and compress, thereby The second spring 54 has a tendency to stretch, which improves the anti-collision ability of the support frame 53. The height of the support plate 5 is adjusted by the lifting component 4, and the first screw 41 is rotated. The lifting block 32 moves up and down in the lifting slot 31 of the fixed plate 3 through the first screw hole 42. The first screw 41 drives the limiting ring 433 to rotate in the limiting slot 432 while penetrating the connecting hole 431 and the limiting slot 432 of the limiting component 43, so that the first screw 41 does not generate displacement when rotating. By pushing one end of the fixing frame 6, under the action of the rotating component 62, the rotating shaft 61 rotates The rotation in the hole 621 and the rotating groove 622 drives the rotating sleeve 623 to rotate in the rotating groove 622, so that the rotating shaft 61 will not be separated from the rotating hole 621, so that the fixation can be stably rotated, and the purpose of convenient adjustment of the horizontal angle of the fire water gun is achieved. Through the connecting component 63, the handle is pushed to make the mounting block 7 rotate on the outer wall of the connecting shaft 631 through the connecting hole 2 632 of the connecting block 633, thereby achieving the purpose of convenient adjustment of the vertical angle of the fire water gun. This structure improves the anti-slip ability of the fire water gun fixing device and improves the stability at the same time.
