Description

Technical Field

[0001] The utility model relates to the field of joints, in particular to a water-leakage-proof fire-fighting joint structure. Background Art

[0002] As one of the most common devices in life, fire hydrants play an irreplaceable role in social fire prevention. When a fire occurs, firefighters only need to install the fire pipe to the water outlet of the fire hydrant, open the fire hydrant, and aim it at the fire site to extinguish the fire. In order to save water resources, the joint structure connecting the fire hydrant must have the characteristic of leak-proof while ensuring quick connection.

[0003] The existing anti-leakage fire joint structure generally arranges a sealing gasket between the water outlet of the joint A and the water inlet of the joint B, and when the buckle protrusion and the buckle groove are closed, the sealing gasket is compacted to perform a leak-proof seal.

[0004] Although this sealing method can effectively prevent leakage, whether it can be completely sealed depends on the tightness of the connection between the closing buckle protrusion and the buckle groove. Once the closing buckle protrusion and the buckle groove do not match, a gap will appear at the connection of the sealing gasket, causing water leakage. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the sealing degree of the existing anti-leakage fire joint structure depends on the sealing degree of the closing buckle protrusion and the buckle groove. If the connection between the closing buckle protrusion and the buckle groove is loose, gaps will appear at both ends of the sealing gasket.

[0006] In order to solve the above technical problems, the technical solution provided by the utility model is: a water-leakage-proof fire-fighting joint structure, including a fire hydrant, the water outlet of the fire hydrant is provided with a joint A, one end of the joint A is provided with a plurality of snap-on protrusions, the water outlet of the joint A is provided with a joint B corresponding to the joint A, the water inlet end of the joint B is provided with a snap-on groove corresponding to the snap-on protrusions, the joint A is connected to the joint B through a sealing gasket, the water outlet end of the joint A is provided with a water-leakage-proof convex groove column, the water inlet end of the joint B is provided with a water-leakage-proof groove column corresponding to the water-leakage-proof convex column groove, the sealing gasket is located between the inner wall of the water-leakage-proof groove column and the outer wall of the water-leakage-proof convex groove column, and the sealing gasket is a water-swelling water-stop gasket.

[0007] As an improvement, an anti-retreat column is provided at the top of the anti-leakage convex groove column to prevent the sealing gasket from sliding out.

[0008] As an improvement, an error groove is provided below the anti-leakage convex groove column to prevent the anti-leakage concave groove column from making an error.

[0009] As an improvement, the snap groove is connected to the snap protrusion through body contact, and the water outlet of the fire hydrant is connected to the water inlet of the connector A through a thread.

[0010] As an improvement, the buckle protrusion passes through the side wall of the water leakage prevention groove column, and a stopper is provided inside the water leakage prevention groove column to prevent the buckle protrusion from sliding out.

[0011] As an improvement, the inner wall dimension length of the anti-leakage water groove column is not greater than the outer wall dimension length of the anti-leakage water convex groove column.

[0012] The advantages of the utility model compared with the prior art are: the device sleeves the sealing gasket on the outer wall of the anti-leakage convex groove column, and the inner wall of the anti-leakage groove column is sleeved on the outer wall of the sealing gasket, so as to seal the anti-leakage groove column and the anti-leakage convex groove column, and the sliding connection between the buckle protrusion and the buckle groove is ensured that the anti-leakage groove column and the anti-leakage convex groove column will not be separated due to water pressure; the sealing gasket is a water-swelling water-stop gasket, which ensures that even if there is a gap when the anti-leakage groove column and the anti-leakage convex groove column are connected, it will be sealed as the water flow soaks.
