Description

Technical Field

[0001] This utility model relates to the field of fire protection technology, specifically to a multifunctional fire hose quick connection device. Background Technology

[0002] Fire hoses are core water delivery equipment in firefighting operations, used to connect fire water sources and nozzles, accurately delivering high-pressure water to the fire scene. They typically consist of two layers: an inner layer made of rubber or polyurethane, providing strong sealing and high-pressure resistance to prevent leakage and withstand water pressures of up to tens of megapascals; and an outer layer mostly made of high-strength polyester, nylon, or other woven materials, which resist abrasion, puncture, and high-temperature baking, adapting to complex fire environments.

[0003] Currently, fire hoses commonly use snap-on rotary connectors, which rely on snap-on positioning and rotational locking to achieve connection. In routine training scenarios, this is convenient to operate and provides good sealing. However, in real fire scenes, amidst high temperatures, dense smoke, and noise, firefighters need to quickly connect the hose to the water source and nozzle. At this point, the operational shortcomings of this type of connector become apparent. Because precise alignment of the snap-on slots and simultaneous rotational locking are required during connection, problems such as snap-on misalignment or incomplete rotation can easily occur in a panic. This not only leads to connection failure but may also waste valuable firefighting time due to repeated adjustments. Utility Model Content

[0004] To solve the above-mentioned problems, this utility model proposes a multifunctional quick-connect device for fire hoses that facilitates connection in chaotic situations and provides a good sealing effect.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is: a multifunctional fire hose quick connection device, comprising:

[0006] One connecting pipe has a docking ring fixedly provided on the outer side of one end, and a docking ring groove is provided on the inner side of the end of the docking ring away from the connecting pipe, and a sealing gasket is fixedly provided in the docking ring groove.

[0007] Connecting pipe two, one end is tightly snapped into the docking ring groove;

[0008] The fixing components are symmetrically arranged on both sides of the docking ring, including buckles and brackets. The buckles are fixed to the docking ring by torsion springs and can rotate. The brackets are fixed to the outer side wall of the connecting pipe and correspond one-to-one with the buckles of the spring seat. The side wall of the bracket is provided with an inner buckling groove. The end of the buckle near the bracket is integrally formed with an insert that matches the inner buckling groove. The insert can be embedded in the inner buckling groove.

[0009] Furthermore, the docking ring sidewall is provided with several anti-slip protrusions.

[0010] Furthermore, the inner walls of the first connecting pipe, the mating ring, and the second connecting pipe are flush.

[0011] Furthermore, the buckle is in the shape of a bent plate, and anti-slip texture is provided on the side wall away from the card seat.

[0012] Furthermore, the insert is semi-cylindrical.

[0013] Compared with existing technologies, the advantages of this invention are as follows: the docking ring has anti-slip raised strips, and the buckle has anti-slip textures, allowing for a stable grip and effortless fastening even with wet or oily hands, eliminating the need for precise operation and facilitating docking in a hurry; furthermore, the insert is semi-cylindrical, resulting in low friction when inserted into the socket, enabling quick docking and avoiding misalignment that wastes time. The sealing gasket inside the docking ring groove tightly fits the connecting pipe, providing a good seal. Simultaneously, the connecting pipe is flush with the inner wall of the docking ring, reducing water flow impact and further ensuring a tight seal, preventing leaks from affecting firefighting.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings.

[0020] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 4 A multifunctional fire hose quick connection device includes: a connecting pipe 1, with a docking ring 2 fixedly provided on the outer side of one end; a docking ring groove provided on the inner side of the end of the docking ring 2 away from the connecting pipe 1; a sealing gasket 3 fixedly provided in the docking ring groove; and several anti-slip protrusions provided on the side wall of the docking ring 2, which can increase the friction between the operator's hand and the docking ring 2, so that even in a fire emergency scenario where the hands are wet or oily, the operator can easily hold the docking ring 2 to perform the connection operation, thus improving the stability of operation.

[0021] Combined with appendix Figure 1Connecting pipe 2 4, one end of which is tightly snapped into the docking ring groove. The inner walls of connecting pipe 1, docking ring 2 and connecting pipe 2 4 are flush, which can prevent water flow from generating eddies at the junction of the three, reduce water flow resistance, ensure the water output efficiency of the fire hose, and at the same time prevent impurities from accumulating on the inner wall protrusions and affecting subsequent use.

[0022] Combined with appendix Figure 1 Appendix Figure 3 Appendix Figure 4 The fixing components are symmetrically arranged on both sides of the docking ring 2, including a buckle 5 and a seat 6. The buckle 5 is fixed to the docking ring 2 by a torsion spring 7 and is rotatable. The seat 6 is fixed to the outer wall of the connecting pipe 4 and corresponds one-to-one with the buckle 5. Its side wall is provided with an inner buckling groove. The end of the buckle 5 near the seat 6 is integrally formed with an insert 8 that matches the inner buckling groove. The insert 8 can be embedded in the inner buckling groove. The buckle 5 is in the shape of a bent plate. The side wall away from the seat 6 is provided with anti-slip texture. The bent structure makes it easy for the operator to press the buckle 5 with their fingers, and the anti-slip texture further increases the contact friction between the hand and the buckle 5, making the separation operation of the buckle 5 and the seat 6 easier and more convenient, and improving the disassembly efficiency of the device. The insert 8 is semi-cylindrical. When the insert 8 is inserted into the inner groove of the card holder 6, the semi-cylindrical arc surface can reduce the frictional resistance between the insert 8 and the inner wall of the inner groove, making the insertion process smoother. At the same time, the arc structure can prevent the insert 8 from being damaged due to excessive force at the corners, thus extending the service life of the insert 8.

[0023] The specific implementation method of this utility model is as follows: First, hold the connecting tube 1 and align the end with the docking ring 2 with the corresponding port of the connecting tube 4, and align the buckle 5 and the seat 6. Push one end of the connecting tube 4 into the docking ring groove inside the docking ring 2. During the pushing process, the anti-slip protrusions on the side wall of the docking ring 2 can increase the friction of the hand, so that even if the hand is wet or oily, the connecting tube 1 can be held stably to avoid slipping and affecting the operation. As the connecting tube 4 is pushed in, the sealing gasket 3 in the docking ring groove will fit tightly against the outer wall of the connecting tube 4. During the process, press the buckle 5 so that it rotates automatically under the action of the torsion spring 7 until the seat 6 is located inside the buckle 5. Release the buckle 5, and it will reset under the action of the torsion spring 7, causing the integrally formed insert 8 at the end of the buckle 5 to be inserted into the inner groove of the seat 6 on the outer wall of the connecting tube 4, thus completing the locking. During disassembly, simply use your finger to press the anti-slip textured part of the buckle 5 away from the card seat 6 to overcome the spring force of the torsion spring 7 and make the insert 8 disengage from the inner groove, thus separating the connecting tube 1 from the connecting tube 2.
