Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment, specifically a quick-installation fire protection interface. Background Technology

[0002] In the field of fire rescue, quick-installation fire hose couplings are key components for ensuring rapid connection of water pipelines and improving emergency response efficiency. The ease of connection and disassembly directly affects the timing of rescue operations. For example, a quick-installation fire hose coupling disclosed in CN 222392266 U uses a structure such as a retaining ring, connecting block, and spring to fix the connector to the fire hydrant. Although it improves the connection stability to some extent, it still has significant drawbacks: the disassembly and assembly process of this coupling requires multiple steps, such as pressing the retaining ring, rotating the connector, pulling the pull plate, and rotating the fixing rod. The steps are cumbersome and lack continuity. In emergency rescue scenarios, each step may lead to errors due to time constraints, prolonging the time required for coupling disassembly and assembly.

[0003] Furthermore, the complex disassembly and assembly process requires a high level of operator proficiency, and in emergency situations, improper operation can easily lead to problems such as loose connections and leaks, further hindering rescue efficiency. Therefore, developing a quick-installation fire hose connector with simpler disassembly and assembly steps and faster operation has become an urgent need to shorten rescue preparation time and improve emergency response efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a quick-installation fire-fighting interface to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A quick-install fire hydrant connector includes a fixed connector installed on a fire hydrant and a connector inserted into the fixed connector and connected to fire water. A fixed ring is fixedly installed on the fixed connector, and a fixed plate is fixedly installed on the side wall of the fixed ring. Multiple circular holes are arrayed on one side of the fixed connector near the fixed ring. Multiple grooves are also formed on the inner wall of the fixed connector corresponding to the circular holes. Limiting elements are movably inserted into the grooves. A circular rod is movably inserted into each of the circular holes. One end of the circular rod passes through the fixed plate and is fitted with a fixing block, while the other end is fixedly connected to the limiting element. A first spring is sleeved on the rod body located between the limiting element and the fixed plate. A limiting ring is fixedly installed on the outer wall of the connector, and an annular groove is formed on the limiting ring to accommodate the insertion of the limiting element. A driving assembly is also provided on the fixed connector to provide power for the multiple circular rods to move synchronously away from the axis of the fixed connector.

[0007] As a further embodiment of this utility model: one side of the limiting member is an inclined surface, and the side of the limiting ring is provided with a bevel with the same inclination angle as the inclined surface.

[0008] As a further embodiment of this utility model: the driving assembly includes a movable tube, a connecting rod, and a second spring. The movable tube is movably sleeved on the fixed joint through the second spring, and multiple connecting rods are hinged to the end face of the movable tube. The multiple connecting rods are connected to the fixed block one by one, and the connecting rods are hinged to the fixed block.

[0009] As a further embodiment of this utility model: the side of the fixing ring is symmetrically fixed with limiting plates on both sides of the fixing plate, and the fixing block is slidably disposed between the two limiting plates.

[0010] As a further embodiment of this utility model: the inner wall of the fixed joint is provided with a plurality of annular grooves, and the outer wall of the connector is provided with an annular sealing rubber ring adapted to the annular grooves.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model's fixed connector and connector employ a plug-in fit between a limiting member and an annular groove. Under the action of a first spring, the limiting member automatically embeds into the annular groove, achieving rapid locking of the connector without complex rotation or pressing operations, simplifying the connection process. The drive component synchronously drives multiple round rods to move away from the axis, thereby pulling the limiting member out of the annular groove, achieving one-click unlocking. This solves the problem of cumbersome disassembly and assembly steps in traditional interfaces, significantly shortening operation time. It is particularly suitable for emergency fire rescue scenarios, preventing missed opportunities due to time-consuming operations. The overall structure is compact, with strong synergy among components, reducing the skill requirements for operators and enabling rapid connection and disassembly of interfaces in emergency situations. This effectively improves the response speed and efficiency of fire rescue, significantly enhancing its practicality. Attached Figure Description

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] Example 1

[0021] Please see Figure 1-5 A quick-install fire hydrant interface includes a fixed connector 1 installed on a fire hydrant and a connector 2 inserted into the fixed connector 1 and connected to the fire water. A fixed ring 3 is fixedly installed on the fixed connector 1, and a fixed plate 4 is fixedly installed on the side wall of the fixed ring 3. The fixed ring 3 and the fixed plate 4 form a limiting mechanism mounting frame. Multiple circular holes 5 are arrayed on one side of the fixed ring 3. Multiple grooves 6 are also formed on the inner wall of the fixed connector 1 corresponding to the circular holes 5. Limiting elements 7 are movably inserted into the grooves 6, and the limiting elements 7 achieve a locking function through radial extension and retraction. A circular rod 8 is movably inserted into the circular holes 5. One end of the circular rod 8 passes through the fixed plate 4 and is fitted with a fixing block 9, while the other end is connected to the limiting element 9. The positioning component 7 is fixedly connected, wherein the round rod 8 is linked to the limiting component 7 and the fixing block 9. The round rod 8 located between the limiting component 7 and the fixing plate 4 is also fitted with a first spring 10, wherein the first spring 10 provides locking elastic force for the limiting component 7. The outer wall of the connector 2 is fixedly provided with a limiting ring 11, and the limiting ring 11 has an annular groove 12 that is adapted to the insertion of the limiting component 7. The annular groove 12 receives the limiting component 7 to form an axial lock. The fixed joint 1 is also provided with a driving component, which is used to provide power for the multiple round rods 8 to move synchronously away from the axis of the fixed joint 1. The driving component realizes one-click unlocking, solving the problem of cumbersome multi-step operation in the background art.

[0022] Example 2

[0023] Please see Figure 2 and Figure 3 One side of the limiting member 7 is an inclined surface, and the side of the limiting ring 11 is provided with a bevel 13 with the same inclination angle as the inclined surface. When the connector 2 is inserted into the fixed connector 1, the inclined surface of the limiting member 7 and the bevel 13 cooperate to achieve automatic guidance and locking during insertion, which further improves the installation efficiency.

[0024] Example 3

[0025] Please see Figure 1 and Figure 2The drive assembly includes a movable tube 14, connecting rods 15, and a second spring 16. The movable tube 14 is a single-handed operating component. The movable tube 14 is movably sleeved on the fixed joint 1 via the second spring 16. The second spring 16 provides the movable tube 14 with a return force. Multiple connecting rods 15 are hinged to the end face of the movable tube 14. The multiple connecting rods 15 are connected one-to-one with the fixed block 9, and the connecting rods 15 are hinged to the fixed block 9. The connecting rods 15 convert the axial displacement of the movable tube 14 into the radial movement of the fixed block 9, and simultaneously unlock all limiting parts 7.

[0026] Example 4

[0027] Please see Figure 4 and Figure 5 The fixed ring 3 is symmetrically fixed with limiting plates on both sides of the fixed plate 4. The fixed block 9 is slidably disposed between the two limiting plates. The limiting plates constrain the movement trajectory of the fixed block 9 to prevent deviation.

[0028] Example 5

[0029] Please see Figure 1 and Figure 2 The inner wall of the fixed joint 1 is also provided with multiple annular grooves, and the outer wall of the connector 2 is equipped with an annular sealing rubber ring 17 that is adapted to the annular grooves. The annular sealing rubber ring 17 ensures high-pressure water sealing and prevents leakage.

[0030] Working principle:

[0031] During connection, the connector 2 is inserted into the fixed connector 1, and the bevel 13 of the limiting ring 11 contacts the inclined surface of the limiting member 7, pushing the limiting member 7 to radially contract and compress the first spring 10; when the limiting ring 11 moves to the point where the annular groove 12 is aligned with the limiting member 7, the first spring 10 pushes the limiting member 7 into the annular groove 12 to complete self-locking, and the annular sealing rubber ring 17 achieves sealing.

[0032] During disassembly, push the movable tube 14 towards the fixed ring 3. The movable tube 14 compresses the second spring 16, and the connecting rod 15 drives all the fixed blocks 9 and the round rod 8 to move radially outward synchronously. The limiting piece 7 disengages from the annular groove 12 and is released from locking, allowing the connector 2 to be pulled out. This design, through the inclined self-locking and linkage unlocking mechanism, achieves a quick operation of "insertion locks, pull releases," solving the efficiency bottleneck of multi-step operations in the background technology and meeting the timeliness requirements of fire rescue.

[0033] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
