Description

Technical Field

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

[0002] Fire hoses are the core tools used in firefighting operations to spray water or other extinguishing agents. Their main function is to extinguish fires or provide cooling and protection by controlling the water flow pattern and range.

[0003] Chinese utility model patent CN218589584U discloses a fire hose nozzle that facilitates water volume adjustment. The main pipe has a valve core on its inner side, a first side cylinder and an end cap are connected to the right side of the main pipe, and a second side cylinder is connected to the left side of the main pipe. The valve core has a water passage hole, the radius of the first arc surface of the water passage hole is larger than the radius of the second arc surface, the top and bottom of the valve core have raised ribs, the first and second side cylinders and the inside of the main pipe all have strip-shaped limiting grooves, the right side of the valve core has a drive gear, the right side of the drive gear has a handwheel, the end cap is rotatably connected to a drive shaft, the raised rib has a lead screw, the end of the lead screw is fixed with a driven gear, and the radius of the drive gear is larger than the radius of the driven gear.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: In the above-mentioned equipment, the main rotating shaft is driven by the handwheel to drive the active gear, so that the radius of the first arc surface of the water passage is greater than the radius of the second arc surface, thereby realizing the adjustment of the water volume. However, the handwheel needs to be turned by one hand, and the other hand needs to hold the side of the main pipe, which is cumbersome and reduces the fire extinguishing efficiency. Utility Model Content

[0005] To solve the above problems, this utility model provides a fire sprinkler nozzle.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a fire sprinkler nozzle includes an inlet pipe, a connecting pipe connected to the inlet pipe is provided on the side wall of the inlet pipe, a sleeve is provided on the side wall of the connecting pipe away from the inlet pipe, a conduit connected to the connecting pipe is provided inside the sleeve, a cross-connector connected to the conduit is provided on the side wall of the sleeve away from the connecting pipe, an outlet pipe is provided on the side of the cross-connector away from the sleeve, a slider is slidably provided inside the conduit, a water outlet groove connected to the water outlet hole in the conduit is provided on the slider, and a closing component is provided on the sleeve for controlling the movement of the slider to control the water output of the outlet pipe.

[0007] By adopting the above technical solution, workers first connect the inlet pipe to the external water supply system, open the water supply valve of the external water supply system, and water flows in through the inlet pipe, then through the conduit and jumper pipe, and finally out through the outlet pipe. When workers need to adjust the water flow rate of the outlet pipe, they control the slider to move through the closing component, so that the water outlet groove on the slider corresponds to the water outlet hole in the conduit, thereby adjusting the water flow rate. This application changes the traditional method of adjusting the water flow rate by requiring two hands, simplifies the operation steps, and improves fire extinguishing efficiency.

[0008] Furthermore, the closing assembly includes a connecting rod fixed to the bottom of the slider, a sliding rod fixed to the side wall of the connecting rod, and a fixing block fixed to the bottom of the sleeve. The fixing block has a groove for the sliding rod to slide. The closing assembly also includes a spring fixed to the side of the groove away from the sliding rod. The side of the spring away from the fixing block abuts against the sliding rod. The bottom of the guide tube has a through hole for the connecting rod to slide. The bottom of the sleeve has a through hole corresponding to the through hole and for the sliding rod to slide.

[0009] By adopting the above technical solution, when the worker needs to reduce the water flow from the outlet pipe, they first hold the connecting rod and move it away from the outlet pipe. The connecting rod moves the slider, thus connecting the water outlet trough with the water outlet hole in the guide tube, thereby reducing the water flow. When the worker needs to increase the water flow, they release the connecting rod. At this time, the spring is pushed back to its original position by the elastic force, which in turn moves the connecting rod and the slider to their original positions, making the water outlet trough and the water outlet hole fully connected, thus increasing the water flow.

[0010] Furthermore, a sealing rubber gasket is attached and fixed at the intersection of the conduit and the slider.

[0011] By adopting the above technical solution, the sealing rubber gasket increases the sealing between the slider and the conduit, preventing water from flowing out.

[0012] Furthermore, the connecting rod has multiple anti-slip grooves on the side away from the slide bar.

[0013] By adopting the above technical solution, the anti-slip groove increases the friction between the worker's hand and the connecting rod.

[0014] Furthermore, an annular groove is provided inside the cross-connector, and an annular block is provided inside the annular groove. A branch pipe communicating with the cross-connector is provided on the side away from the sleeve. Multiple branch pipes are provided. Corresponding holes corresponding to the multiple branch pipes are provided on the annular block. A fixing rod is fixed to the top of the annular block. An arc-shaped groove for the fixing rod to slide is provided on the cross-connector.

[0015] By adopting the above technical solution, when workers need to increase the coverage area of ​​the water spray, they rotate the fixed rod, which drives the annular block to rotate, thereby aligning the corresponding holes on the annular block with the branch pipes, thus increasing the coverage area of ​​the water spray. Conversely, workers rotate the fixed rod in the opposite direction, dislocating the corresponding holes on the annular block from the branch pipes, thus closing the corresponding holes and reducing the coverage area of ​​the water spray.

[0016] Furthermore, an annular rubber pad is attached and fixed to the side of the annular block away from the sleeve.

[0017] By adopting the above technical solution, the setting of the annular rubber gasket increases the sealing between the annular block and the cross-connector, preventing water from flowing out.

[0018] Furthermore, a positioning block is provided at the top of the sleeve.

[0019] By adopting the above technical solution, the positioning block is designed to facilitate the operator to hold it with their left hand while holding the fixing block and operating the connecting rod with their right hand, thereby increasing the stability of the water outlet and improving the water spraying efficiency.

[0020] Furthermore, the side wall of the fixing block is provided with an anti-slip rubber pad.

[0021] By adopting the above technical solution, the anti-slip rubber pad increases the friction between the worker's hands and the fixed block.

[0022] In summary, this utility model has the following beneficial effects: The operator first connects the inlet pipe to the external water supply system, opens the water supply valve of the external water supply system, and the water flows in from the inlet pipe, then passes through the conduit and the cross-connection in sequence, and finally exits through the outlet pipe. When the operator needs to adjust the water flow of the outlet pipe, the sliding block is controlled by the closing component to move, so that the water outlet groove on the sliding block corresponds to the water outlet hole in the conduit, thereby realizing the adjustment of the water flow.

[0030] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0031] like Figure 1-6 As shown in the illustration, this application discloses a fire sprinkler nozzle, including an inlet pipe 1, a connecting pipe 11, a sleeve 12, a conduit 13, a crossover pipe 14, an outlet pipe 15, a slider 2, and a closing assembly 3. The connecting pipe 11 is disposed on the side wall of the inlet pipe 1 and communicates with it. The sleeve 12 is disposed on the side wall of the connecting pipe 11 away from the inlet pipe 1. The conduit 13 is disposed inside the sleeve 12 and communicates with the connecting pipe 11. The crossover pipe 14 is disposed on the side wall of the sleeve 12 away from the connecting pipe 11 and communicates with the conduit 13. The outlet pipe 15 is disposed on the side of the crossover pipe 14 away from the sleeve 12. The slider 2 is slidably disposed inside the conduit 13. The slider 2 is provided with an outlet groove 21, which communicates with an outlet hole in the conduit 13.

[0032] The closing component 3 is mounted on the sleeve 12 and is used to control the movement of the slider 2 to control the water flow rate of the outlet pipe 15. The closing component 3 includes a connecting rod 31, a sliding rod 32, a fixing block 33, and a spring 34. The connecting rod 31 is fixed to the bottom of the slider 2, and the sliding rod 32 is fixed to the side wall of the connecting rod 31. The fixing block 33 is fixed to the bottom of the sleeve 12, and a groove 331 is provided on the fixing block 33 for the sliding rod 32 to slide. The spring 34 is fixed to the side of the groove 331 away from the sliding rod 32, and the side of the spring 34 away from the fixing block 33 abuts against the sliding rod 32. In this embodiment, a through hole 131 is provided at the bottom of the guide tube 13 for the connecting rod 31 to slide. A through hole 121 is provided at the bottom of the sleeve, which corresponds to the through hole 131 and allows the sliding rod 32 to slide.

[0033] First, the worker connects the inlet pipe 1 to the external water supply system and opens the water supply valve. Water enters through the inlet pipe 1, then flows through the conduit 13 and the jumper pipe 14, and finally exits through the outlet pipe 15. When the worker needs to adjust the water flow of the outlet pipe 15, they first hold the connecting rod 31 and move it away from the outlet pipe 15. The connecting rod 31 moves the slider 2, thus connecting the water outlet trough 21 with the water outlet hole in the conduit 13, thereby reducing the water flow of the outlet pipe 15. When the worker needs to increase the water flow of the outlet pipe 15, they release the connecting rod 31. At this time, the spring 34 is pushed by the elastic force to reset the slider 32, which in turn moves the connecting rod 31 and the slider 2 to their original positions, making the water outlet trough 21 fully connected with the water outlet hole, thus increasing the water flow.

[0034] In this embodiment, a sealing rubber gasket 4 is affixed and fixed at the intersection of the conduit 13 and the slider 2. The sealing rubber gasket 4 increases the sealing between the slider 2 and the conduit 13, preventing water leakage. In this embodiment, an anti-slip groove 311 is provided on the side of the connecting rod 31 away from the slide rod 32, and multiple anti-slip grooves 311 are provided. The anti-slip groove 311 increases the friction between the operator's hand and the connecting rod 31.

[0035] In this embodiment, an annular groove 141 is formed inside the cross-connector 14, and an annular block 5 is disposed within the annular groove 141. A branch pipe 6 is disposed on the side of the cross-connector 14 away from the sleeve 12, and multiple branch pipes 6 are provided. Corresponding holes 51 are formed on the annular block 5, and each corresponding hole 51 corresponds one-to-one with a branch pipe 6. A fixing rod 52 is fixed to the top of the annular block 5, and an arc-shaped groove 142 is formed on the cross-connector 14, which allows the fixing rod 52 to slide. When the operator needs to increase the coverage area of ​​the water spray, the fixing rod 52 is rotated, which drives the annular block 5 to rotate, thereby aligning the corresponding hole 51 on the annular block 5 with the branch pipe 6, thus increasing the coverage area of ​​the water spray. When the operator rotates the fixing rod 52 in the opposite direction, the corresponding hole 51 on the annular block 5 is displaced from the branch pipe 6, thus closing the corresponding hole 51 and reducing the coverage area of ​​the water spray.

[0036] In this embodiment, an annular rubber pad 7 is attached and fixed to the side of the annular block 5 away from the sleeve 12. The annular rubber pad 7 increases the sealing between the annular block 5 and the cross-connector 14, preventing water leakage. In this embodiment, a positioning block 8 is provided on the top of the sleeve 12. The positioning block 8 facilitates the operator's left hand gripping the fixed block 33 and operating the connecting rod 31, increasing the stability of the water outlet pipe 15 when water is discharged and improving the water spraying efficiency. In this embodiment, an anti-slip rubber pad 9 is provided on the side wall of the fixed block 33. The anti-slip rubber pad 9 increases the friction between the operator's hand and the fixed block 33.
