[0028] In this embodiment, when the first clamping joint 1 and the second clamping joint 2 are connected, the L-shaped plate 3 on the first clamping joint 1 is inserted into the groove 4, and then the first clamping joint 1 and the second clamping joint 2 are rotated in the opposite direction, so that the L-shaped plate 3 is rotated to conflict with the fixing plate 5, and then the fixing rod 6 is driven to move under the movement of the elastic component 9, and the fixing rod 6 drives the fixing block 7 to be inserted into the fixing groove 8, so that the L-shaped plate 3 can be fixed, thereby avoiding the loose connection between the first clamping joint 1 and the second clamping joint 2, facilitating the use of the fire hose, and improving the use effect of the fire hose.

[0029] In a further embodiment, Figure 2-3 As shown, the elastic component 9 includes a first slide groove 91 opened on the outer wall of the second card joint 2, and a first slider 92 fixed to the fixing rod 6 is slidably connected in the first slide groove 91. The first slider 92 is fixedly connected to the first slide groove 91 through a first spring 93. A first positioning block 10 is fixed to the outer wall of the first card joint 1, and a second positioning block 11 corresponding to the first positioning block 10 is fixed to the outer wall of the second card joint 2.

[0030] When making the connection, the first clamping joint 1 and the second clamping joint 2 are brought into contact with each other, and the L-shaped plate 3 is inserted into the groove 4. Then, the first clamping joint 1 and the second clamping joint 2 are rotated in the opposite direction, so that the L-shaped plate 3 is rotated to conflict with the fixing plate 5. During the rotation of the first clamping joint 1 and the second clamping joint 2, when the first positioning block 10 and the second positioning block 11 are rotated to the corresponding positions, the rotation is stopped. At this time, under the elastic action of the first spring 93, the movement of the first slider 92 is driven, the first slider 92 drives the fixing rod 6 to move, and the fixing rod 6 drives the fixing block 7 to move, so that the fixing block 7 is inserted into the fixing groove 8, and the L-shaped plate 3 can be fixed, thereby connecting and fixing the first clamping joint 1 and the second clamping joint 2, avoiding loosening and falling off between the first clamping joint 1 and the second clamping joint 2, facilitating the use of the fire hose, and improving the use effect of the fire hose.

[0031] In a further preferred embodiment of the present invention, Figure 2As shown, a sealing ring 12 that contacts the second clamping joint 2 is provided on one side of the first clamping joint 1, an annular rubber pad 13 is fixed on one side of the sealing ring 12, an annular groove 14 that adapts to the annular rubber pad 13 is opened on one side of the first clamping joint 1, the annular groove 14 is connected to the annular rubber pad 13 through a reset assembly 15, and a sealing assembly 16 is provided in the annular groove 14.

[0032] When the first clamping joint 1 and the second clamping joint 2 are connected correspondingly, the first clamping joint 1 and the second clamping joint 2 are sealed by the sealing ring 12 and the annular rubber pad 13. At the same time, with the cooperation of the reset component 15 and the sealing component 16, the sealing ring 12 and the annular rubber pad 13 are driven to move, so that the sealing ring 12 is in full contact with the second clamping joint 2, thereby facilitating full sealing between the first clamping joint 1 and the second clamping joint 2, facilitating the use of the fire hose, and improving the use effect of the fire hose.

[0033] In a further embodiment, Figure 2-4 As shown, the reset assembly 15 includes a second slider 151 fixedly arranged on both sides of the annular rubber pad 13, and second slide grooves 152 for the second slider 151 to slide are opened on both sides of the inner wall of the annular groove 14. The second slide groove 152 is fixedly connected to the second slider 151 through a second spring 153. The sealing assembly 16 includes a first airbag 161 fixedly arranged between the annular rubber pad 13 and the annular groove 14, and a second airbag 162 connected to the first airbag 161 is fixed on the inner wall of the annular groove 14.

[0034] When the first clamping joint 1 and the second clamping joint 2 are connected, the sealing ring 12 on the first clamping joint 1 contacts the second clamping joint 2, and then the sealing ring 12 is driven to move under the extrusion between the first clamping joint 1 and the second clamping joint 2, and the sealing ring 12 drives the movement of the annular rubber pad 13. During the movement of the annular rubber pad 13, the second slider 151 is driven to squeeze the second spring 153, so that the second spring 153 provides a reaction force to the annular rubber pad 13, which is convenient for maintaining the stability of the annular rubber pad 13. At the same time, during the movement of the annular rubber pad 13, the first air bag 161 is squeezed, and the first air bag 161 inflates the second air bag 162 under the extrusion action, so that the second air bag 162 seals the annular rubber pad 13 and the annular groove 14, so that the sealing ring 12 is convenient for fully sealing the first clamping joint 1 and the second clamping joint 2, avoiding leakage caused by insufficient connection between the sealing ring 12 and the first clamping joint 1 and the second clamping joint 2, facilitating the use of the fire hose, and improving the use effect of the fire hose.

When the first positioning block 10 and the second positioning block 11 are rotated to the corresponding positions, the rotation is stopped. At this time, under the elastic action of the first spring 93, the first slider 92 is driven to move, and the first slider 92 drives the fixing rod 6 to move, and the fixing rod 6 drives the fixing block 7 to move, so that the fixing block 7 is inserted into the fixing groove 8, and the L-shaped plate 3 can be fixed, so that the first clamping joint 1 and the second clamping joint 2 are connected and fixed, and loosening and falling off between the first clamping joint 1 and the second clamping joint 2 are avoided, which is convenient for the use of the fire hose and improves the use effect of the fire hose. During the contact, the sealing ring 12 on the first clamping joint 1 contacts the second clamping joint 2, and then the sealing ring 12 is driven to move under the extrusion between the first clamping joint 1 and the second clamping joint 2, and the sealing ring 12 drives the movement of the annular rubber pad 13. During the movement of the annular rubber pad 13, the second slider 151 is driven to squeeze the second spring 153, so that the second spring 153 provides a reaction force to the annular rubber pad 13, which is convenient for maintaining the stability of the annular rubber pad 13. At the same time, during the movement of the annular rubber pad 13, the first airbag 161 is squeezed, and the first airbag 161 inflates the second airbag 162 under the extrusion, so that the second airbag 162 seals the annular rubber pad 13 and the annular groove 14, so that the sealing ring 12 is convenient for fully sealing the first clamping joint 1 and the second clamping joint 2, avoiding leakage caused by insufficient connection between the sealing ring 12 and the first clamping joint 1 and the second clamping joint 2, facilitating the use of the fire hose and improving the use effect of the fire hose.
