Description

Technical Field

[0001] This application relates to the field of fire water pipe fitting technology, and in particular to a fire water pipe fitting that is easy to assemble and disassemble. Background Technology

[0002] In firefighting operations, the rapid connection and stable sealing of water pipe joints are crucial for ensuring firefighting efficiency and rescue safety. Traditional fire water pipe joints mostly use threaded or flanged connections, which have significant limitations. Threaded connections require repeated manual tightening, which is time-consuming and cannot meet the needs of rapid response in emergencies such as fires. Flange connections require the use of wrenches and other tools to tighten bolts, which is not only cumbersome to install but also requires more space, making them extremely inconvenient to operate in narrow or complex rescue environments.

[0003] Furthermore, existing fire hose joints have poor sealing performance, making them prone to leakage under high-pressure water flow, leading to a drop in water pressure and affecting firefighting effectiveness. Some joint structures are also prone to wear and loosening after frequent disassembly and assembly, reducing connection stability and posing a safety hazard of pipe detachment.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] To address the issues of threaded connections requiring repeated manual tightening, which is time-consuming and unsuitable for rapid response in emergencies such as fires, and flange connections requiring wrenches and other tools for bolt tightening, which are not only cumbersome to install but also require ample installation space, this application provides a fire water pipe connector that is easy to install and disassemble.

[0006] The fire water pipe joint provided in this application adopts the following technical solution for easy assembly and disassembly:

[0007] A fire hose connector that is easy to assemble and disassemble includes a pipe, which consists of a first pipe and a second pipe. The inner wall of the second pipe has an integral structure with an inner pipe at its top end. Several sliding rods are fixed at equal intervals on the edge of the top end of the second pipe. The top end of each sliding rod has a retractable elastic block inside. The outer wall of the first pipe has a set of sliding tracks that are adapted to the sliding rods at equal intervals. The end of each sliding track has a communicating movable cavity. One side of the movable cavity has a snap-fit ​​mechanism. The snap-fit ​​mechanism includes a sliding block and an insert rod fixed to the inner wall of the sliding block.

[0008] Preferably, connector one and connector two are fixed to the outer walls of the opposite ends of pipe one and pipe two, respectively.

[0009] Preferably, the bottom end of the outer wall of the second pipe is provided with threads, and a matching threaded fastening sleeve is connected to the outside of the threads.

[0010] Preferably, the inner wall of the pipe has an integral extension pipe in the middle, and the side of the extension pipe has a sealing cavity adapted to the inner pipe.

[0011] Preferably, the top side wall of the slide rod has an insertion hole adapted to the insertion rod, and the inside of the top of the slide rod has a contraction opening adapted to the elastic block. A spring for support is connected between the elastic block and the inner wall of the contraction opening.

[0012] Preferably, one side of the movable cavity is provided with an adjustment port adapted to the sliding block, the inner wall of the adjustment port is provided with a sliding hole adapted to the insertion rod, and a spring is sleeved on the outside of the insertion rod.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] This application allows the insertion rod to retract by adjusting the sliding block. Combined with the guide of the sliding rod and track, initial insertion is quickly completed. The elastic block and insertion rod automatically reset to form a double lock. Tightening the threaded fastening sleeve further strengthens the seal. The entire process requires no tools, making it highly efficient and time-saving. For disassembly, simply unscrew the threaded fastening sleeve and pull the sliding block to easily separate the pipe. This multi-layered structure ensures the joint remains stable and does not detach under high-pressure water flow, effectively preventing leakage. Simultaneously, the safety anti-misoperation design avoids operational errors, providing reliable support for firefighting operations. Attached Figure Description

[0019] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0020] This application discloses a fire hose connector that is easy to assemble and disassemble. (Refer to...) Figures 1-2 The system includes pipes, which consist of pipe 1 (2) and pipe 2 (4). Connector 1 (1) and connector 2 (3) are fixed to the outer walls of the ends of pipes 1 (2) and 2 (3) respectively. The inner wall of the top of pipe 2 (4) has an integral inner tube 8. Several sliding rods 6 are equidistantly fixed to the edge of the top of pipe 2 (4). The top of each sliding rod 6 has a retractable elastic block 11 inside, and a contraction opening 10 adapted to the elastic block 11 is opened inside the top of the sliding rod 6. A spring for support connects the elastic block 11 and the inner wall of the contraction opening 10, facilitating the retraction and reset of the elastic block 11 within the inner wall of the contraction opening 10.

[0021] In this application, the inner wall of pipe 2 has an integral extension tube 13 in the middle. The edge of the extension tube 13 has a sealing cavity 12 that matches the inner tube 8. The inner tube 8 is inserted into the sealing cavity 12 to form an initial seal, preventing water leakage. The outer wall of pipe 2 has a set of slide rails 14 that match the slide rod 6 at equal intervals. The end of the slide rail 14 has a communicating movable cavity 15. The sliding guide of the slide rod 6 and the slide rail 14, together with the anti-reverse limit of the elastic block 11, form the first layer of mechanical locking.

[0022] Combination Figures 2-3 As shown, a latching mechanism is provided on one side of the movable cavity 15. The latching mechanism includes a sliding block 17 and an insertion rod 18 fixed to the inner wall of the sliding block 17. The top side wall of the sliding rod 6 has an insertion hole 9 adapted to the insertion rod 18. An adjustment port 16 adapted to the sliding block 17 is provided on one side of the movable cavity 15. The inner wall of the adjustment port 16 has a sliding hole adapted to the insertion rod 18. A spring element 19 is sleeved on the outside of the insertion rod 18. By adjusting the sliding block 17 back through the adjustment port 16, the insertion rod 18 can be retracted. Combined with the guiding design of the sliding rod 6 and the slide rail 14, pipe 2 and pipe 4 can be quickly aligned and initially connected without additional tools. The automatic reset mechanism of the spring element 19 and the elastic block 11 allows the insertion rod 18 to automatically engage with the insertion hole 9 and the elastic block 11 to pop out to its limit, significantly reducing installation time and meeting the rapid connection requirements in fire emergency scenarios.

[0023] In this application, the bottom end of the outer wall of pipe 2 4 is provided with thread 7, and a matching threaded fastening sleeve 5 is connected to the outside of thread 7. The tightening of threaded fastening sleeve 5 and thread 7 wraps around and reinforces the connection from the outside. The triple structure works together to ensure that the joint remains stable under the impact of high-pressure water flow and avoids the risk of falling off.

[0024] The implementation principle of the fire water pipe joint that is easy to assemble and disassemble in this application embodiment is as follows:

[0025] When connecting the water pipes, align the ends of pipe 2 and pipe 4, aligning the sliding rod 6 with the slide rail 14. Next, by adjusting the port 16, the sliding block 17 is retracted, and the insertion rod 18 retracts against the resistance of the spring 19, pushing pipe 2 forward. The sliding rod 6 slides along the slide rail 14, while the inner tube 8 inserts into the sealing cavity 12, forming a preliminary seal. When the sliding rod 6 slides to the end of the slide rail 14 and enters the movable cavity 15, the elastic block 11 pops out from the contraction port 10 under the action of the spring, preventing the sliding rod 6 from sliding out in the opposite direction. At this point, release the sliding block 17. Due to the elasticity of the spring 19, the sliding block 17 returns to its original position, and the insertion rod 18 is inserted into the insertion hole 9 of the sliding rod 6, completing the locking mechanism and ensuring a secure connection between pipe 2 and pipe 4, preventing separation. Finally, rotate the threaded fastening sleeve 5 so that it covers the outer wall of the connection between pipe 2 and pipe 4 and tightens with the thread 7 of pipe 4, further enhancing the sealing and stability of the joint.

[0026] When disassembling the water pipe, first unscrew the threaded fastening sleeve 5 to release the external sealing pressure. Then, pull the sliding block 17 to disengage the insertion rod 18 from the insertion hole 9. At this time, the elastic block 11 is compressed and retracts into the contraction port 10. Next, slide pipe 2 in the opposite direction along the slide rail 14 to disengage the sliding rod 6 from the movable cavity 15. The inner pipe 8 is then pulled out from the sealing cavity 12, which quickly separates pipe 2 from pipe 4, completing the disassembly process.
