[0002] Fire fighting buckle is a kind of fire fighting equipment, mainly used between fire hoses or fire hose guns. The hose interface is used to connect the hoses with the hoses, fire trucks, fire hydrants, and water guns to transport water or foam mixture for fire fighting. It consists of the main body, sealing ring seat, rubber sealing ring and retaining ring. There is a groove on the sealing ring seat for tying the hose.

[0003] The existing fire-fighting buckles can basically meet the use needs. When disassembling and assembling, you only need to align the fire-fighting buckle on one side with the fire-fighting buckle on the other side, and then rotate the fire-fighting buckle on one side so that the plug hook on the inner wall of the fire-fighting buckle on this side and the plug plate on the inner wall of the fire-fighting buckle on the other side can be plugged in and disconnected, so that quick disassembly and assembly can be achieved. However, due to the lack of a limiting component, when firefighters are dragging water guns and fire hoses, the plug-in buckle between the plug hook and the plug plate is not strong enough, and it is inevitable that the buckles on both sides will loosen and fall off, affecting firefighting and rescue work. Based on this, the utility model provides a quick-release fire-fighting buckle. Utility Model Content

[0028] Principle of the utility model

[0029] When in use, when docking and installing the connector 1 and the connector 2, the staff aligns the interfaces of the connector 1 and the connector 2 together, so that the hook 5 goes deep into the inside of the connector 1. At this time, the hook 5 is located between the L-shaped plug plates 4. Then, the connector 2 is rotated to make the hook 5 in the connector 2 move toward the direction close to the L-shaped plug plate 4, so that the hook groove of the hook 5 is plugged and hooked on the horizontal plate of the L-shaped plug plate 4 until the limit rod 8 blocks the horizontal plate of the L-shaped plug plate 4. Then the staff holds the annular handle 10, pulls it outward and rotates it. The annular handle 10 moves outward to drive the connecting rod 9, the slide plate 7, and the limit rod 8 to move outward. At this time, the reset spring 11 is compressed by force. , so that the limiting rod 8 is retracted into the hollow block 6, and the annular handle 10 is held and rotated to make the connecting buckle 2 2 and the plug hook 5 continue to move toward the L-shaped plug plate 4 until the plug hook 5 is blocked and limited by the vertical plate of the L-shaped plug plate 4. At this time, the limiting rod 8 is connected with the limiting hole 14, and the annular handle 10 is released. The return spring 11 in the compressed state rebounds and resets, driving the connecting rod 9, the slide plate 7, and the limiting rod 8 to move inward, and the limiting rod 8 is inserted into the limiting hole 14, so that the plug hook 5 can be locked on the L-shaped plug plate. The whole installation process is labor-saving and convenient, and the connecting buckle 1 and the connecting buckle 2 2 can be firmly connected together to prevent loosening and falling off, which affects the firefighting and rescue work.

[0030] When disassembly is required, the staff directly holds the annular handle 10, pulls it outward and rotates it, so that the limiting rod 8 is moved out of the limiting hole 14, and the hook 5 can fall off from the L-shaped plug plate 4 as the annular handle 10 rotates, so that the fire-fighting buckle can be quickly disassembled.
