Technical Field

[0001] This utility model relates to the field of fire hose sprinklers, and in particular to a water hose sprinkler. Background Technology

[0002] A fire sprinkler head is a device used to control and direct the flow of fire-fighting water. It is usually connected to a fire-fighting water pipe and is used to adjust the direction and spray pattern of the water flow during fire extinguishing.

[0003] During the installation of the sprinkler head on the fire hose, if it is used for a long time or operated in harsh environments, the threads at the connection may wear or be damaged, deformed or fail, resulting in an unstable connection, increasing the risk of detachment and affecting the effectiveness of fire extinguishing. Utility Model Content

[0004] The technical problem this utility model aims to solve is that during the use of the sprinkler head body installed on the fire water pipe body, if it is used for a long time or operated in a harsh environment, the threads at the connection may wear or be damaged, deformed or fail, resulting in an unstable connection, increasing the risk of falling off, and affecting the fire extinguishing effect.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a handheld and stable fire hose sprinkler head, including a sprinkler head body, a fire hose body being threadedly connected to the inner wall of one end of the sprinkler head body, a hand handle being fixedly connected to the outer surface of the sprinkler head body, a limiting device being provided on the outer surface of one end of the sprinkler head body, and an auxiliary device being provided on one side of the hand handle. The limiting device can perform secondary limiting and fixing of one end of the fire hose body screwed onto one end of the sprinkler head body, and the auxiliary device can bind and limit the hand holding the hand handle to the hand handle, thereby improving the stability of the handheld grip.

[0006] Preferably, the limiting device includes two limiting frames and two pads. A plurality of first protrusions are symmetrically fixedly connected to the outer surface of one end of the nozzle body. One side of one end of the two limiting frames is rotatably connected to one side of the two pairs of first protrusions respectively. One side of the limiting frame abuts against one side of one end of the fire water pipe body. A threaded rod is rotatably connected to the inner wall of one end of the limiting frame. One end of the threaded rod is inserted into the inner wall of one end of the other limiting frame. A screw hole block is fixedly connected to one end of the threaded rod.

[0007] The effect achieved by the above-mentioned components is as follows: By setting a limiting device, when the opposite water pipe is screwed into the inner wall of one end of the sprinkler head body for installation, the two limiting devices can be rotated to a certain angle in the inner walls of the two pairs of first protrusions, so that one end of the limiting device abuts against one side of the fire water pipe body. Then, the threaded rod is rotated to a certain angle in the inner wall of one end of the limiting frame, so that the other end of the threaded rod is inserted into the inner wall of one end of another limiting frame. Then, the screw hole block is screwed into the threaded rod to a certain position, so that one side of the threaded rod abuts against one side of the limiting frame, thus limiting and fixing it. In this way, after the two limiting frames limit and fix the fire water pipe body a second time, they limit and fix each other, making the sprinkler head body installed on the fire water pipe body more firmly and stably, reducing the risk of falling off during use, improving the fire extinguishing effect, and facilitating use.

[0008] Preferably, the pad is fitted onto the outer surface of one end of the threaded rod, and the pad is fitted between the threaded rod on one side of the threaded hole block and the side of the limiting frame.

[0009] The effect achieved by the above components is that by setting the pad, the contact area between one side of the screw hole block and the other side of the limit frame can be increased, making it more secure and stable when limiting and fixing the two limit frames.

[0010] Preferably, an anti-slip block is fixedly connected to one side of the limiting frame, and the anti-slip block is made of rubber.

[0011] The effect achieved by the above components is that by setting anti-slip blocks, the contact friction on one side of the limit bracket can be increased, making it more secure and stable when it abuts against the main body of the fire water pipe, and less prone to slippage.

[0012] Preferably, bearings are fixedly connected to both outer surfaces of one end of the limiting frame, and the outer ring of the bearing is fixedly connected to one side of the first protrusion.

[0013] The effect achieved by the above components is that by setting bearings, the rotational wear between one end of the limit frame and the first protrusion can be reduced, making rotation easier and improving service life.

[0014] Preferably, the auxiliary device includes a rectangular ring block, one end of which is fixedly connected to one side of a hand handle. A strap is fixedly connected to one side of the hand handle, and hook-and-loop fasteners are symmetrically fixedly connected to one side of the strap. Loose-and-loop fasteners are also symmetrically fixedly connected to one side of the strap. The strap, hook-and-loop fasteners, and loose-and-loop fasteners are inserted into the inner wall of the rectangular ring block.

[0015] The effect achieved by the above-mentioned components is as follows: By setting up the auxiliary device, when firefighters are holding the handle for firefighting, after the firefighters hold the handle, the strap can be passed through the inner wall of the rectangular ring block, and then folded back and tightened so that the strap is close to the back of the firefighter's hand. Then, the hook and loop fastener on one side of the strap is attached to the corresponding position of the loop fastener for fixation, thus binding and limiting the hand holding the handle to the handle, improving the stability of the hand and making it less likely to fall off during use.

[0016] Preferably, a second protrusion is fixedly connected to one side of the strap, and the cross-section of the second protrusion is trapezoidal.

[0017] The effect achieved by the above-mentioned components is that by setting the second protrusion, the area of ​​one end of the strap can be reduced, so that one end can be quickly aligned with the inner wall of the rectangular ring and inserted, which facilitates installation.

[0018] Preferably, a round block is fixedly connected to the outer surface of the rectangular ring block, and a plurality of locking holes are provided on one side of the strap, with the round block inserted into the inner wall of the locking holes.

[0019] The effect achieved by the above components is as follows: by setting the round block and the locking hole, when the strap is inserted into the inner wall of the rectangular ring block and then folded back, the corresponding locking hole on the strap can be fitted onto the outer surface of the round block to initially fix the strap, making the strap more secure and stable when fixing the hand holding the handle, and less prone to loosening.

[0020] The beneficial effects of this utility model are:

[0021] By setting a limiting device, when installing the opposite water pipe by screwing it into the inner wall of one end of the sprinkler head body, the two limiting devices can be rotated to a certain angle in the inner walls of the two pairs of first protrusions, so that one end of the limiting device abuts against one side of the fire water pipe body. Then, the threaded rod is rotated to a certain angle in the inner wall of one end of the limiting bracket, so that the other end of the threaded rod is inserted into the inner wall of one end of another limiting bracket. Then, the screw hole block is screwed into the threaded rod to a certain position, so that one side of the threaded rod abuts against one side of the limiting bracket, thus limiting and fixing it. In this way, the two limiting brackets can limit and fix the fire water pipe body twice, and then limit and fix each other, making the sprinkler head body installed on the fire water pipe body more firmly and stably, reducing the risk of falling off during use, improving the fire extinguishing effect, and facilitating use.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0030] Figure 1-4 The illustrated handheld stable fire hose sprinkler head includes a sprinkler body 1, a fire hose body 5 threadedly connected to the inner wall of one end of the sprinkler body 1, a handle 4 fixedly connected to the outer surface of the sprinkler body 1, a limiting device 2 provided on the outer surface of one end of the sprinkler body 1, and an auxiliary device 3 provided on one side of the handle 4. The limiting device 2 can provide secondary limiting and fixing of one end of the fire hose body 5 screwed onto one end of the sprinkler body 1, and the auxiliary device 3 can bind and limit the hand holding the handle 4 to the handle 4, thereby improving the stability of the handheld grip.

[0031] Figure 2The limiting device 2 shown includes two limiting frames 22 and two pads 25. Several first protrusions 21 are symmetrically fixedly connected to the outer surface of one end of the nozzle body 1. The two sides of one end of the two limiting frames 22 are rotatably connected to one side of the two pairs of first protrusions 21 respectively. One side of the limiting frame 22 abuts against one side of one end of the fire water pipe body 5. A threaded rod 23 is rotatably connected to the inner wall of one end of the limiting frame 22. One end of the threaded rod 23 is inserted into the inner wall of one end of another limiting frame 22. A screw hole block 24 is fixedly connected to one end of the threaded rod 23. When installing the sprinkler head body 1 by screwing the opposite water pipe into the inner wall of one end, the two limiters in the inner walls of the two pairs of first protrusions 21 can be rotated to a certain angle so that one end of them abuts against one side of the fire water pipe body 5. Then, the threaded rod 23 can be rotated to a certain angle in the inner wall of one end of the limiter 22 so that the other end of it can be inserted into the inner wall of one end of the other limiter 22. Then, the screw hole block 24 can be screwed into the threaded rod 23 to a certain position so that one side of it abuts against one side of the limiter 22, thus limiting and fixing it. In this way, after the two limiters 22 limit and fix the fire water pipe body 5 a second time, they can limit and fix each other, making the sprinkler head body 1 more firmly and stably installed on the fire water pipe body 5, reducing the risk of falling off during use, improving the fire extinguishing effect, and making it convenient to use.

[0032] Figure 2 The pad 25 shown is fitted onto the outer surface of one end of the threaded rod 23, between one side of the threaded rod 23 located in the threaded hole block 24 and the other side of the limiting frame 22. By setting the pad 25, the contact area between one side of the threaded hole block 24 and the other side of the limiting frame 22 is increased, making the limiting frame 22 more secure and stable when it is fixed. An anti-slip block 26, made of rubber, is fixedly connected to one side of the limiting frame 22. The anti-slip block 26 increases the contact friction on one side of the limiting frame 22, making it more secure and stable when it abuts against the fire hose body 5, and less prone to slippage. Bearings 27 are fixedly connected to both outer surfaces of one end of the limiting frame 22, and the outer ring of the bearing 27 is fixedly connected to one side of the first protrusion 21. The bearings 27 reduce rotational wear between one end of the limiting frame 22 and the first protrusion 21, facilitating rotation and improving service life.

[0033] Figure 3 and Figure 4The auxiliary device 3 shown includes a rectangular ring block 31. One end of the rectangular ring block 31 is fixedly connected to one side of the handle 4. A strap 32 is fixedly connected to one side of the handle 4. Hook and loop fasteners 33 and loop fasteners 34 are symmetrically fixedly connected to one side of the strap 32. The strap 32, hook and loop fasteners 33, and loop fasteners 34 are inserted into the inner wall of the rectangular ring block 31. When firefighters hold the handle 4 to extinguish fires, after the firefighters hold the handle 4, they can pass the strap 32 through the inner wall of the rectangular ring block 31, then fold it back and tighten it so that the strap 32 is close to the back of the firefighter's hand. Then, the hook and loop fasteners 33 on one side of the strap 32 are attached to the corresponding position of the loop fasteners 34 for fixation. This binds and limits the hand holding the handle 4 to the handle 4, improving the stability of the hand and making it less likely to fall off during use.

[0034] Figure 3 and Figure 4 A second protrusion 35 is fixedly connected to one side of the strap 32, and the cross-section of the second protrusion 35 is trapezoidal. By setting the second protrusion 35, the area of ​​one end of the strap 32 can be reduced, allowing one end to be quickly aligned with the inner wall of the rectangular ring block 31 and inserted, facilitating installation. A round block 37 is fixedly connected to the outer surface of the rectangular ring block 31, and several locking holes 36 are opened on one side of the strap 32. The round block 37 is inserted into the inner wall of the locking holes 36. By setting the round block 37 and the locking holes 36, when the strap 32 is inserted into the inner wall of the rectangular ring block 31 and then folded back, the corresponding locking holes 36 on the strap 32 can be fitted onto the outer surface of the round block 37 to initially fix the strap 32, making the strap 32 more secure and stable when the hand holding the handle 4 is fixed, and less prone to loosening.

[0035] Working principle: When installing the sprinkler head body 1 by screwing the opposite water pipe into the inner wall of one end, the two limiters in the inner walls of the two pairs of first protrusions 21 can be rotated to a certain angle so that one end of them abuts against one side of the fire water pipe body 5. Then, the threaded rod 23 is rotated to a certain angle in the inner wall of one end of the limiter 22 so that the other end of it is inserted into the inner wall of one end of the other limiter 22. Then, the screw hole block 24 is screwed into the threaded rod 23 to a certain position so that one side of it abuts against one side of the limiter 22, thus limiting and fixing it. In this way, after the two limiters 22 limit and fix the fire water pipe body 5 a second time, they limit and fix each other, making the sprinkler head body 1 more firmly and stably installed on the fire water pipe body 5, reducing the risk of falling off during use, improving the fire extinguishing effect, and making it convenient to use.

[0036] When firefighters are extinguishing fires by holding the handle 4, after they hold the handle 4, they can pass the strap 32 through the inner wall of the rectangular ring block 31, and then fold it back and tighten it so that the strap 32 is close to the back of the firefighter's hand. Then, the hook and loop fastener 33 on one side of the strap 32 is attached to the corresponding position of the loop fastener 34 to fix it. This binds and limits the hand holding the handle 4 to the handle 4, improving the stability of the hand and making it less likely to fall off during use.

[0037] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
