The pull plate 212 moves away from the fixed plate 201, so that the first spring 205 is in a stretched state, at the same time, the round rod 202 slides on the fixed plate 201, so that the limiting plate 203 moves away from the limiting frame 204, until the limiting plate 203 completely eliminates the limiting effect of the limiting frame 204. One end of the limiting plate 203 is fixedly connected with two limiting rods 210, the arc surfaces of the two limiting rods 210 are slidingly connected with the fixed plate 201. The limiting plate 203 moves to drive the limiting rods 210 to slide on the fixed plate 201, so that the position of the limiting plate 203 is prevented from deviating during movement. One end of the limiting rod 210 is fixedly connected with a limiting block 211, the outside of the pull plate 212 is fixedly connected with a U-shaped anti-skid pad 209. The U-shaped anti-skid pad 209 increases the friction effect. Both sides of the pull plate 212 are fixedly connected with a T-shaped groove plate 207, the inside of the T-shaped groove plate 207 is slidingly connected with a T-shaped plate 208. The pull plate 212 moves to drive the T-shaped groove plate 207 to slide on the T-shaped plate 208. Both ends of the T-shaped plate 208 are fixedly connected with a fixed rod 206, one end of the four fixed rods 206 is fixedly connected with the connector body 1. The fixed rod 206 is fixed on the connector body 1, and the T-shaped plate 208 is fixed on the fixed rod 206.

[0034] Referring to Figure 4 As shown, in the embodiment: the sealing device 3 includes a fixed ring 31, the arc surface of the fixed ring 31 is fixedly connected with the connector 4, one end of the fixed ring 31 close to the connector body 1 is fixedly connected with a second spring 32, one end of the second spring 32 is fixedly connected with a connecting ring 33, the arc surface of the connecting ring 33 is slidingly connected with the connector 4. The connecting ring 33 moves close to the fixed ring 31, so that the second spring 32 is in a compressed state. One end of the connecting ring 33 is fixedly connected with a sealing gasket ring 34, the sealing gasket ring 34 is made of rubber. The sealing gasket ring 34 is fixed on the connecting ring 33. One end of the sealing gasket ring 34 is fixedly connected with a sealing ring 35, the sealing ring 35 is made of rubber. The sealing ring 35 is fixed on the sealing gasket ring 34. One end of the sealing ring 35 is fixedly connected with a guide ring 36. The guide ring 36 prevents the sealing ring 35 from deforming.

[0035] Working principle: When it is necessary to assemble the connector body 1 and the connector head to prevent reverse rotation, the operator first pulls the U-shaped anti-slip pad 209 away from the fixed plate 201 using the limiting device 2. The force of the U-shaped pad is transmitted to the pull plate 212. The movement of the pull plate 212 stretches the first spring 205. At the same time, the round rod 202 slides on the fixed plate 201, driving the limiting plate 203 to move until the limiting plate 203 contacts the fixed plate 201. Then, the connector head and the connector body 1 are assembled by screwing them together. At this time, the position of the limiting frame 204 is aligned with the limiting plate 203, and the U-shaped anti-slip pad can be released. 209. Eliminating the limiting effect of the pull plate 212, the first spring 205 rebounds, causing the pull plate 212 to move the round rod 202, and moving the limiting plate 203 into the limiting frame 204, thus completing the limiting of the limiting frame 204 and preventing the connector from reversing. Through the limiting device 2, the problem of traditional multi-purpose fire hydrant connectors, which are basically connected by threaded connection, is solved. After the fire hydrant connector is connected, the flowing water will generate a large impact force. The impact force will cause the threaded connection of the connector to reverse under the impact of the water flow, thus causing the connector to detach and affecting the fire protection use.

[0036] When it is necessary to increase the sealing between the connector body 1 and the connector head through the sealing device 3, the operator first installs and fixes the fixing ring 31 inside the connector head. When the connector head and the connector body 1 are screwed together, the threaded end of the connector body 1 abuts against the sealing gasket ring 34, causing the second spring 32 to contract and generate elastic force that is transmitted to the connecting ring 33. The connecting ring 33 drives the sealing gasket ring 34 to continuously abut against the threaded end of the connector body 1, increasing the sealing performance. Through the sealing device 3, the problem of poor sealing effect of traditional multi-purpose fire hydrant connectors, which easily leads to water waste, is solved.
