[0026] Example

[0027] like Figures 1-4 As shown, the present invention proposes a fire-fighting water pipe connector, including a main pipe 1. A first connector 2 is fixedly installed at one end of the main pipe 1. The end of the first connector 2 is chiseled with several connecting slots 23. A second connector 3 is installed at the end of the first connector 2 away from the main pipe 1. Several connecting plates 31 are fixedly installed at one end of the second connector 3. The connecting plates 31 are inserted into the matching connecting slots 23 and engaged with them. The connecting plates 31 can be fixed by bolts installed on the first connector 2, ensuring that the first connector 2 and the second connector 3 are firmly connected as one unit. The ends of the first connector 2 and the second connector 3 that are close to each other are respectively chiseled with a first annular groove 21 and a second annular groove 33. A rubber sealing ring 22 is installed between the first annular groove 21 and the second annular groove 33. When the first connector 2 and the second connector 3 are joined together, the rubber sealing ring 22 is stably clamped in the gap between the two connectors, which can seal the gap and prevent water leakage.

[0028] A clamp 4 is fixedly installed at the end of the second connector 3 away from the first connector 2. The clamp 4 can clamp and fix the fire hose sleeved on the end of the second connector 3, ensuring that the fire hose can be firmly connected to the second connector 3 as one unit. A second pair of connecting pipes 34 is fixedly installed at one end of the second connector 3. A rubber sleeve 35 is sleeved on the second pair of connecting pipes 34. When the fire hose is sleeved on the second pair of connecting pipes 34, the clamp 4 fixes the end of the fire hose on the second pair of connecting pipes 34. At this time, the rubber sleeve 35 seals the part where the fire hose is connected to the second pair of connecting pipes 34, enhancing its anti-leakage effect.

[0029] Furthermore, the clamp 4 consists of a semi-circular clamping plate 41, a positioning plate 42, and a limiting screw 43. The positioning plate 42 is fixedly installed at one end of the second connector 3. Two limiting screws 43 are fixedly installed between the two positioning plates 42 in the same group. The limiting screws 43 pass through the circular openings carved on the semi-circular clamping plate 41 and are movably connected to it, ensuring that the semi-circular clamping plate 41 can move along the limiting screws 43, which facilitates the adjustment of the distance between the semi-circular clamping plate 41 and the second connecting pipe 34, and makes it convenient for workers to operate during the installation of fire hoses.

[0030] Secondly, two limiting nuts 44 are threaded onto the aforementioned limiting screw 43. These limiting nuts 44 are positioned between the positioning plate 42 and the semi-circular clamping plate 41. When the semi-circular clamping plate 41 is in close contact with the outer surface of the fire hose, the limiting nuts 44 are rotated and made to fit against the semi-circular clamping plate 41. At this time, the semi-circular clamping plate 41 can be locked and fixed, ensuring that the semi-circular clamping plate 41 can firmly clamp the fire hose, effectively improving the firmness of the connection between the end of the fire hose and the second connector 3.

[0031] Furthermore, the second connector 3 is fixedly installed with a first pair of connecting pipes 32 at one end near the first connector 2. When the first connector 2 and the second connector 3 are joined together, the first pair of connecting pipes 32 are inserted into the first connector 2 and can act as an inner lining support inside the joint of the two connectors, ensuring that the first connector 2 and the second connector 3 can be joined together more stably.

[0032] In this embodiment, when the second connector 3 needs to be installed on the main pipe 1, the second connector 3 is first mated with the first connector 2. At this time, the connecting plate 31 is inserted into the connecting slot 23 so that the two connectors can fit together. Then, the bolt installed on the outer wall of the first connector 2 is rotated. When the threaded end of the bolt is inserted into the connecting slot 23, it can be threadedly connected with the connecting plate 31. Then, the connecting plate 31 is locked and fixed to ensure that the first connector 2 and the second connector 3 can be firmly connected as one. At this time, the rubber sealing ring 22 is tightly clamped between the two connectors to seal the gap at the connection and prevent water leakage at the joint of the two connectors.

[0033] When the fire hose needs to be installed on the second connector 3, first put the end of the fire hose onto the second connecting pipe 34, and then push the semi-circular clamp 41 toward the second connecting pipe 34. After the semi-circular clamp 41 is in close contact with the outer surface of the fire hose, rotate the limiting nut 44 threaded on the limiting screw 43 to limit the semi-circular clamp 41, ensuring that the semi-circular clamp 41 can tightly clamp the fire hose. At this time, the rubber sleeve 35 is tightly clamped between the second connecting pipe 34 and the inner wall of the fire hose, which can seal the connection between the fire hose and the second connecting pipe 34 and prevent water leakage at the connection.

[0034] The second connector 3 in this application is fixed to the first connector 2 by plug-in installation, and the fire hose is installed on the second connector 3 by clamping. Compared with the traditional threaded connection structure that requires rotation installation, it can solve the problem of the torsion generated by rotation causing the rubber seal (rubber sealing ring 22 and rubber sleeve 35) to twist and deform. It avoids the rubber seal leaving gaps at the water pipe connection due to twisting, so that the rubber seal has a more stable sealing effect and effectively reduces the probability of water leakage at the water pipe connection.

[0035] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
