The right side of the first protection cover 101 is movably connected to a second protection cover 102, which is sleeved on the right side of the surface of the connecting ring 4.

[0025] As a technical optimization solution of the utility model, by setting the protective component 10, it is convenient for the user to put the first protective cover 101 on the bottom of the surface of the connecting ring 4, and then put the second protective cover 102 on the right side of the surface of the connecting ring 4, so as to cover the connection between the first fire protection pipe 1 and the second fire protection pipe 2, and avoid the situation where foreign objects collide and affect the installation effect.

[0026] refer to Figure 3 The first protective cover 101 is fixedly connected to the right side of the front and rear sides with a plug-in board 11, and the second protective cover 102 is fixedly connected to the left side of the front and rear sides with a connector 12. The left side of the connector 12 is plugged into the plug-in board 11, and the left side of the surface of the connector 12 is sleeved with a rubber limiting ring 13.

[0027] As a technical optimization scheme of the utility model, by setting the plug board 11, the connecting piece 12 and the rubber limiting ring 13, when the user needs to connect the first protective cover 101 with the second protective cover 102, the left side of the connecting piece 12 will be plugged into the right side of the plug board 11, and the rubber limiting ring 13 will be deformed. When the rubber limiting ring 13 moves to the left side of the plug board 11, it will be restored, so that the connecting piece 12 cannot be easily separated from the plug board 11, so that the first protective cover 101 and the second protective cover 102 can be quickly connected and installed.

[0036] The working principle and usage process of the utility model are as follows: when it is necessary to connect the first fire-fighting pipe 1 with the second fire-fighting pipe 2, the user first moves the stress ring 8 to the inner side of the connecting ring 4, and then the user uses the bolt 7 to fix the first mounting ring 5 and the second mounting ring 6, and then the first fire-fighting pipe 1 and the second fire-fighting pipe 2 will move toward the stress ring 8, so that the connecting ring 4 will press and fix the stress ring 8, and at the same time, the fitting groove 9 opened at the bottom of the first fire-fighting pipe 1 and the fitting groove 9 opened at the top of the second fire-fighting pipe 2 will fit with the two sides of the sealing ring 3, so as to use the sealing ring 3 for sealing, and at the same time, when the stress ring 8 is pressed and fixed, the sealing ring 3 will not be offset, and then the user can put the first protective cover 101 on the bottom of the surface of the connecting ring 4, and then put the second protective cover 102 on the right side of the surface of the connecting ring 4, so as to cover the connection between the first fire-fighting pipe 1 and the second fire-fighting pipe 2, avoid the situation where foreign objects collide and affect the installation effect, and have the ability to assist in the installation of the sealing ring 3.

[0037] To sum up: the fire-fighting pipe connection sealing structure, by setting the first mounting ring 5 and the second mounting ring 6, using bolts 7 to fix the first mounting ring 5 and the second mounting ring 6, so that the force ring 8 is pressed and fixed, and at the same time, the fitting groove 9 opened at the bottom of the first fire-fighting pipe 1 and the fitting groove 9 opened at the top of the second fire-fighting pipe 2 will fit with the two sides of the sealing ring 3, so as to use the sealing ring 3 for sealing, which solves the problem of lack of installation structure for the sealing ring, and directly inserting the sealing ring into the installation ring, resulting in the sealing ring being not stable enough and prone to deviation and shaking when the user connects the fire-fighting pipe.
