Technical Field

[0001] This utility model belongs to the field of fire-fighting equipment technology, specifically relating to a fire-fighting water spray nozzle with adjustable water volume. Background Technology

[0002] As a key component of automatic sprinkler fire extinguishing systems, the technology of sprinkler heads has evolved from simple spraying to multi-functional integrated systems. This involves the optimization of core parameters such as response time index and water density. They are widely used in various building sites, not only for fire extinguishing but also for fire isolation and fire control functions, demonstrating their important role and wide application in modern fire safety.

[0003] In the use of existing water spray nozzles, users often have to go through a series of cumbersome steps to adjust the water flow, including rotating the regulating valve and adjusting the pressure setting. These operations are not only time-consuming, but may also lead to operational errors in emergency situations, affecting the fire extinguishing efficiency and ease of use of the water spray nozzle. Therefore, a fire-fighting water spray nozzle with adjustable water flow has emerged. Utility Model Content

Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0026] Example

[0027] Reference Figures 1-5 This is an embodiment of the present utility model, which provides a fire-fighting water spray nozzle with adjustable water volume, comprising:

[0028] The connecting mechanism 100 includes a connecting seat 101, a latch 102 fixedly installed at the bottom of the connecting seat 101, a slot 103 opened on the side wall of the connecting seat 101, and a connecting pipe 104 communicating with the side wall of the connecting seat 101.

[0029] The adjustment mechanism 200 includes a transfer pipe 201 connected to the side wall of the connecting pipe 104, an anti-slip block 202 fixedly installed on the side wall of the transfer pipe 201, a water spray assembly 203 disposed at the end of the transfer pipe 201, and a control assembly 204 disposed in the inner cavity of the transfer pipe 201.

[0030] Specifically, the water spray assembly 203 includes a connecting shell 203a connected to the end of the transfer pipe 201 via a bearing, a torsion thread 203b disposed on the inner wall of the connecting shell 203a, a pressurizing chamber 203c disposed in the inner cavity of the connecting shell 203a, and a nozzle 203d communicating with the end of the connecting shell 203a.

[0031] Furthermore, the control component 204 includes a fixing component 204a disposed in the inner cavity of the transfer tube 201, and an adjusting component 204b disposed in the inner cavity of the connecting shell 203a to cooperate with the fixing component 204a.

[0032] The fixing component 204a includes a fixing strip 204a-1 fixedly installed in the inner cavity of the transfer tube 201, and a connecting rod 204a-2 fixedly installed on the side wall of the fixing strip 204a-1. The fixing component 204a also includes a sleeve 204a-3 sleeved on the surface of the connecting rod 204a-2, a tension spring 204a-4 fixedly installed at the end of the connecting rod 204a-2, and a piston 204a-5 fixedly installed at the end of the tension spring 204a-4.

[0033] Preferably, the piston 204a-5 is made of rubber material to ensure smooth movement, while the rubber material also has good sealing properties.

[0034] The adjusting component 204b includes a connecting pipe 204b-1 connected to the end of the sleeve 204a-3, an inlet pipe 204b-2 connected to the side wall of the connecting pipe 204b-1, and a transmission plate 204b-3 sleeved on the surface of the connecting pipe 204b-1. The adjusting component 204b also includes a connecting cylinder 204b-4 fixedly installed at the end of the connecting pipe 204b-1, an outlet 204b-5 opened on the side wall of the connecting cylinder 204b-4, and a water-blocking ball 204b-6 slidably connected to the inner wall of the connecting cylinder 204b-4.

[0035] It should be noted that the transmission plate 204b-3 is movably connected to the torsion thread 203b, ensuring that the connecting pipe 204b-1 can be moved when the connecting shell 203a rotates. At the same time, the transmission plate 204b-3 ensures the seal at the connection between the transfer pipe 201 and the water spray assembly 203, ensuring that the connected water source will not affect the control of the water output.

[0036] In use, the fire hose is connected via the latch 102 on the connecting seat 101, and the end of the hose is secured by the latch 103. Water is then supplied through the transfer pipe 201 into the sprinkler assembly 203, from which the water is sprayed out. To adjust the water flow, the connecting shell 203a is twisted, causing it to rotate and rotate the connecting thread. This rotation drives the transmission plate 204b-3 to move back and forth, which in turn moves the connecting pipe 204b-1. The fixing strip 204a-1 secures the connecting rod 204a-2. Pulling the tension spring 204a-4... 204a-4 pulls piston 204a-5 to move towards fixed bar 204a-1. Piston 204a-5 pulls water-blocking ball 204b-6 to move towards fixed bar 204a-1. The area of ​​water-blocking ball 204b-6 blocking outlet 204b-5 is controlled according to the number of twists, thereby reducing the water output. When water-blocking ball 204b-6 completely blocks outlet 204b-5, the nozzle is closed. Twisting water spray assembly 203 in the opposite direction increases the water output. The setting of pressurization chamber 203c ensures the distance of water source spraying, and the setting of nozzle 203d ensures easy control of water flow direction.

[0037] In summary, the fire hose is connected via the latch 102 on the connecting seat 101, and the end of the hose is secured by the slot 103, allowing for quick connection to the water source. This enables convenient installation and rapid response. The water source flows into the sprinkler assembly 203 through the transfer pipe 201, and is then sprayed out through the sprinkler assembly 203, achieving efficient fire extinguishing. When adjusting the water volume, the connecting shell 203a is twisted, causing the connecting thread to rotate. Through the precise cooperation of the transmission plate 204b-3, the connecting pipe 204b-1, the fixing strip 204a-1, the tension spring 204a-4, the piston 204a-5, and the water-blocking ball 204b-6, the water output can be finely adjusted. This design makes operation simpler and improves the efficiency and controllability of fire extinguishing. The pressurization chamber 203c ensures the distance of the water spray, while the nozzle 203d facilitates the control of the water flow direction, making the sprinkler head more flexible and effective in practical applications, and significantly improving the safety and efficiency of fire fighting operations.
