Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

As shown in fig. 1-4, the fire-fighting foam bolt provided in this embodiment includes a bolt body 1, a pressure regulating and stabilizing device for controlling water pressure and a mixing device for mixing foam and water are disposed in the bolt body 1, and is the same as other foam bolts, and the fire-fighting foam bolt provided in this application further includes a base 2, the base 2 is disposed at the bottom of the bolt body 1 for supporting the bolt body 1, and further includes two liquid outlet pipes 3, the number of the liquid outlet pipes 3 is two, the two liquid outlet pipes 3 are respectively disposed at the left and right sides of the bolt body 1, and further includes a liquid outlet cover 33, the liquid outlet cover 33 is located at a liquid outlet of the liquid outlet pipe 3, a rotating hinge 311 is disposed at a connection portion between the liquid outlet cover 33 and the top of the liquid outlet pipe 3, and the liquid outlet cover 33 is lifted and closed by the rotating hinge 311, the foam bolt is used without screwing the liquid outlet cover 33 by a tool such as a wrench, and with the help of the rotating, the liquid outlet pipe is opened by lifting the liquid outlet cover 33, so that the foam bolt is convenient for common people to use, a layer of bulge can be added on the outer ring of the buckle to form a buckle in order to ensure the tightness degree of the buckle, and the bulge is not needed to be added if the liquid outlet cover 33 is normally buckled and is relatively tight.

In order to support the opened liquid outlet cover 33, further, the liquid outlet cover 33 is supported by a link mechanism, the link mechanism comprises movable hinges 312 arranged on the tube walls at two sides of the liquid outlet tube 3 and the inner wall of the liquid outlet cover 33, and a link 313 connecting the tube walls at two sides of the liquid outlet tube 3 and the movable hinges 312 on the inner wall of the liquid outlet cover 33, wherein the movable hinges 312 are also arranged between the link 313, after the liquid outlet cover 33 is opened, a straight line is formed between the tube walls at two sides of the liquid outlet tube 3 and the movable hinges 312 and the link 313 on the inner wall of the liquid outlet cover 33, so as to support the opened liquid outlet cover 33, and after the liquid outlet cover 33 is closed, two folding lines are formed between the tube walls at two sides of the liquid outlet tube 3 and the movable hinges 312 and the link 313 on the inner wall of the.

In order to replace the liquid outlet pipe 3 conveniently, further, due to the frequent buckling of the liquid outlet cover 33, the liquid outlet pipe 3 is worn frequently, so that the tightness degree of the liquid outlet cover 33 during buckling is affected, therefore, the section of the liquid outlet pipe 3 which is buckled frequently needs to be replaced, but if the whole liquid outlet pipe 3 is replaced, materials are wasted, so that the liquid outlet pipe 3 can be changed into a structure composed of two sections of pipelines, the two sections of pipelines are screwed through the pipe thread 32, and only the liquid outlet pipe 3 with one section of the liquid outlet cover 33 needs to be detached separately during replacement.
