DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-5 In this embodiment, a fire-fighting water pipe connector for firefighting includes a first pipe head 1, a first reinforcement ring 2 is fixedly installed on the right side of the first pipe head 1, a first connector 3 is fixedly installed on the right side of the first reinforcement ring 2, a second connector 4 is movably installed on the right side of the first connector 3, a second reinforcement ring 5 is fixedly installed on the right side of the second connector 4, a second pipe head 6 is fixedly installed on the right side of the second reinforcement ring 5, a fastening mechanism 7 is arranged inside the first connector 3, two baffles 8 are fixedly installed inside the first connector 3, a sealing ring 9 is movably installed inside the first connector 3, a connecting ring 10 is fixedly installed on the left side of the second connector 4, and a limiting plate 11 is fixedly installed on the top and bottom of the connecting ring 10;

[0022] The fastening mechanism 7 includes a limit seat 701, the limit seat 701 is fixedly installed inside the first connecting head 3, the limit seat 701 is fixedly installed inside the limit seat 701, a mounting block 702 is fixedly installed on the right side of the mounting block 702, a telescopic rod 703 is fixedly installed on the outer surface of the telescopic rod 703, a push plate 705 is fixedly installed on the right end of the telescopic rod 703, a fastening ring plate 706 is fixedly installed on the right side of the push plate 705, and sliders 707 are fixedly installed on the top and bottom of the fastening ring plate 706.

[0023] In the case implementation, the settings of the first pipe head 1 and the first reinforcement ring 2 as well as the first connecting head 3, the second pipe head 6, the second reinforcement ring 5, and the second connecting head 4 can provide an installation and fixing effect for the equipment, and at the same time strengthen the fixation of the equipment. The setting of the baffle 8 can provide a limit for the limit plate 11, so that the limit plate 11 is stuck on the left side of the baffle 8. The setting of the connecting ring 10 can extend the limit plate 11 into the first connecting head 3, so that the limit plate 11 is stuck on the left side of the baffle 8. The setting of the sealing ring 9 can strengthen the sealing effect of the equipment and prevent water leakage.

[0024] When implementing, follow these steps:

[0025] 1) First, align the first connector 3 and the second connector 4, and displace the limit plate 11 and the baffle 8, and align the slot and the sealing ring 9, and then directly fit the second connector 4 onto the first connector 3;

[0026] 2) Then the connecting ring 10 will extend to the inside of the annular groove inside the first connecting head 3, and the limiting plate 11 will fit the fastening ring plate 706. At this time, the second connecting head 4 is pushed hard to make the limiting plate 11 compress the fastening ring plate 706;

[0027] 3) As the fastening ring plate 706 is compressed, the telescopic rod 703 and the return spring 704 are squeezed, and the second connector 4 is rotated 90 degrees to change the angle of the limit plate 11, and the limit plate 11 and the baffle plate 8 are located in the same straight line;

[0028] 4) Finally, loosen the second connector 4, and the reset spring 704 resets the telescopic rod 703 through its reaction force, and pushes the push plate 705 to reset, and finally resets the fastening ring plate 706 to push the limit plate 11 against the left side of the baffle 8 to complete the fixation. When disassembly is required, it is only necessary to twist the second connector 4 to displace the limit plate 11 and the baffle 8.

[0029] To sum up, the fire-fighting water pipe connector for firefighting has a better fixing effect by setting the fastening mechanism 7, and is more convenient in the fixing method. It changes the traditional complicated fixing method, effectively saves the test pieces for connecting and fixing the equipment, and improves the use efficiency. At the same time, due to the setting of the sealing ring 9, the sealing effect of the equipment is further improved, and the structure is further stabilized, which effectively improves the pressure-bearing capacity of the equipment. Compared with the existing equipment, it is more outstanding in use effect and more practical.
