[0026] 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. 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.
[0027] See also Figures 1 to 5The utility model provides a technical solution: a fire hydrant connection terminal, including a fire hydrant body 1, both sides of the surface of the fire hydrant body 1 are connected through the connection terminal 2, the top surface of the connection terminal 2 is connected through the water distribution pipe 3, the inner wall of the water distribution pipe 3 is fixedly installed with a support frame 4, the top surface of the support frame 4 is fixedly provided with a telescopic mechanism 5, and the top of the telescopic mechanism 5 is fixedly provided with a closing cover 6. Through the arrangement of the water distribution pipe 3, the telescopic mechanism 5 and the closing cover 6, the fire hose is connected to the connection terminal 2. When the fire hydrant body 1 discharges water, the instantaneous water flow is large, part of the water source surges through the water distribution pipe 3, and the closing cover 6 is pushed open. The telescopic spring 501 and the A hydraulic rod 502 are stretched accordingly, and part of the water source is discharged from the water distribution pipe 3, thereby achieving the effect of reducing the instantaneous water pressure and avoiding excessive instantaneous water pressure to cause fire. After the hose bursts and the water flow stabilizes, the telescopic spring 501 drives the closing cover 6 to reset and close the water distribution pipe 3. A fixing ring 7 is fixedly installed on one side of the surface of the connecting terminal 2. A connecting strip 8 is welded on the bottom surface of the fixing ring 7. A lower fixing ring 9 is welded on the edge of the top surface of the connecting strip 8. An upper fixing ring 10 is hinged on the edge of the top surface of the lower fixing ring 9 through a hinge. Fire hose fixings 11 are fixedly installed on the surfaces of the lower fixing ring 9 and the upper fixing ring 10. Through the setting of the fire hose fixings 11, after the fire hose is connected, the upper fixing ring 10 is covered, and the connecting bolts 13 are screwed to fix it, and then the two groups of B hydraulic rods 1101 are opened, driving the fixing plate 1102 and the anti-slip plate 12 to press against the surface of the fire hose, and reinforcing the connection between the fire hose and the connecting terminal 2 to prevent the fire hose from loosening and falling off.
[0028] The telescopic mechanism 5 includes a telescopic spring 501 fixedly arranged on the top surface of the support frame 4, and the interior of the telescopic spring 501 is sleeved with an A hydraulic rod 502. Through the setting of the telescopic mechanism 5, it plays a role of synchronous telescoping when the closing cover 6 is pushed out by the water body. After the water flow is stable, the closing cover 6 can close the water distribution pipe 3.
[0029] The bottom of the A hydraulic rod 502 is fixedly mounted on the top of the support frame 4, and the top of the A hydraulic rod 502 is fixedly mounted on the bottom surface of the closing cover 6. The setting of the A hydraulic rod 502 plays a damping role to avoid water leakage when the water flow is stable.
[0030] The fire hose fixing 11 includes a B hydraulic rod 1101 fixedly mounted on the surface of the lower fixing ring 9 and the upper fixing ring 10. A fixing plate 1102 is fixedly mounted on one end of the B hydraulic rod 1101. The setting of the fire hose fixing 11 serves to reinforce the connection between the fire hose and the connecting terminal 2.
[0031] The bottom surface of the fixing plate 1102 is affixed with an anti-skid sheet 12 , which is made of rubber. The anti-skid sheet 12 can increase friction and protect the surface of the fire hose joint.
[0032] A connecting plate is welded on one side of the lower fixing ring 9 and the upper fixing ring 10. A connecting hole is opened on the surface of the connecting plate. The internal thread of the connecting hole is penetrated by a connecting bolt 13. The setting of the connecting bolt 13 plays a role in connecting the lower fixing ring 9 and the upper fixing ring 10.
[0033] The bottom surface of the closing cover 6 is sleeved with an A waterproof sealing ring 14, and the setting of the A waterproof sealing ring 14 plays a role in sealing the water distribution pipe 3. The side of the connecting terminal 2 is sleeved with a B waterproof sealing ring 15, and the setting of the B waterproof sealing ring 15 plays a role in sealing the connection of the connecting terminal 2.
[0034] Two groups of connecting ropes 16 are symmetrically arranged at the bottom of the surface of the fire hydrant body 1. A terminal cover 17 is fixedly arranged at one end of the connecting rope 16. The terminal cover 17 serves to cover the connecting terminal 2 after use.
[0035] In the utility model, the working steps of the device are as follows:
[0036] Step 1: Open the terminal cover 17, put the B waterproof sealing ring 15 on the connection terminal 2, and then connect the interface of the fire hose to the connection terminal 2. At this time, the interface of the fire hose fits the lower fixing ring 9;
[0037] Step 2: Then cover the upper fixing ring 10 on the lower fixing ring 9, tighten the connecting bolts 13 to fix it, and then open the two groups of B hydraulic rods 1101, drive the fixing plate 1102 and the anti-slip plate 12 to press against the surface of the fire hose, and reinforce the connection between the fire hose and the connecting terminal 2;
[0038] The third step: after the fire hydrant body 1 is passed through water, the instantaneous water flow is relatively large, and part of the water source surges up through the water distribution pipe 3, pushing the closing cover 6 open. The telescopic spring 501 and the A hydraulic rod 502 are stretched accordingly, and part of the water source is discharged from the water distribution pipe 3, reducing the instantaneous water pressure to avoid the fire hose bursting due to excessive instantaneous water pressure. After the water flow stabilizes, the telescopic spring 501 drives the closing cover 6 to reset and close the water distribution pipe 3.
