[0004] In order to achieve the above purpose, a fire protection pipe quick repair joint is provided, comprising: a repair joint ring block and a fire protection pipe body, wherein the fire protection pipe body is tightly fixed on the inner side of the repair joint ring block.

[0005] The threaded surface at the outer end of the emergency joint ring block is screwed with a joint ring and a pressure holding ring. The joint ring surface is respectively connected to an upper anti-slip pad and a lower anti-slip pad through an adjusting stud. The upper anti-slip pad and the lower anti-slip pad are pressed onto the outer surface of the fire pipe body. The side end of the emergency joint ring block is connected to a metal hose through a threaded interface, and the pipe mouth end of the metal hose is provided with an external threaded pipe head.

[0006] Furthermore, the emergency repair joint ring block is composed of two upper and lower symmetrical half ring blocks pressed together at the outer end of the fire protection pipe body, and a sealing gasket is bonded to the inner ring surface of the emergency repair joint ring block.

[0007] Furthermore, a spacer block is welded on the outer surface of the emergency repair joint ring block; and the joint ring and the pressure-holding ring are respectively screwed and attached to the left and right sides of the spacer block.

[0008] Furthermore, the outer end surfaces of the upper anti-slip pad and the lower anti-slip pad are connected to the adjusting studs through a connecting plate, and a push block is welded to the outer surface of the joint ring.

[0009] Furthermore, the left and right ends of the inner side of the emergency joint ring block are respectively pressed with a fire protection pipe body and an external threaded pipe head, and the threaded interface at the side end of the emergency joint ring block is screwed with the external threaded pipe head.

[0010] Furthermore, a water-blocking gasket is sleeved on the surface of the externally threaded pipe head; and the water-blocking gasket is sealed and pressed against the inner wall of the side end of the emergency joint ring block.

[0011] Furthermore, the emergency repair joint ring block, joint collar, holding collar, upper anti-slip pad, lower anti-slip pad and adjusting stud constitute a quick connection mechanism for the fire protection pipe body and the metal hose.

[0012] The beneficial effect of the present invention is that the fire-fighting pipe quick repair joint of the present invention utilizes the joint ring and the pressure-holding ring that are screwed on the outer side of the repair joint ring block to seal and press the repair joint ring block on the outer surface of the fire-fighting pipe body and the metal hose, so that the damaged two ends of the fire-fighting pipe body and the metal hose form a normal liquid pipeline, which is convenient for fast screwing in and installing the repair joint, and facilitates a more firm and tight connection between the fire-fighting pipe and the repair joint, effectively preventing leakage of the repair joint installed with the fire-fighting pipe, and at the same time widening the length adjustment range of the repair joint, thereby improving the practicality of the fire-fighting pipe quick repair joint.
