Detailed Implementation

[0029] Example 1

[0030] like Figure 1-4 As shown, the present invention proposes a sealing device for outdoor fire-fighting equipment, including a connecting sleeve 2, a sealing sleeve 5, and a sleeve 6 for being fitted onto the outside of the outlet of the fire hydrant body 1.

[0031] The outlet of the fire hydrant body 1 is provided with a connecting pipe 4 for connecting with the fire hydrant body 1 in use;

[0032] The sleeve 6 is wrapped around the outside of the end of the connecting pipe 4;

[0033] The connecting sleeve 2 is rotatably installed on the outside of the connecting pipe 4 and wraps around the outside of the sleeve 6;

[0034] The sealing sleeve 5 is fitted on the outside of the end of the connecting pipe 4 and located inside the sleeve 6. One end of the sealing sleeve 5 extends between the outlet of the fire hydrant body 1 and the end of the connecting pipe 4, and the other end extends between the end of the connecting pipe 4 and the end of the sleeve 6.

[0035] In this embodiment, by placing the sealing sleeve 5 on the outer side of the end of the connecting pipe 4 and moving the connecting pipe 4 towards the outlet of the fire hydrant body 1, the connecting pipe 4 is inserted into the sleeve 6, and the sealing sleeve 5 is connected to the inner wall of the sleeve 6, thus sealing the connection between the connecting pipe 4 and the sleeve 6. Simultaneously, the connecting sleeve 2 is rotated outside the connecting pipe 4, connecting the connecting pipe 4 to the outlet end of the fire hydrant body 1, fixing the connecting pipe 4 to the inner side of the sleeve 6. At the same time, one end of the sealing sleeve 5 extends between the outlet of the fire hydrant body 1 and the end of the connecting pipe 4, and the other end extends between the end of the connecting pipe 4 and the end of the sleeve 6. When the connecting sleeve 2 moves the connecting pipe 4 towards the fire hydrant body 1, the connecting pipe 4 simultaneously squeezes both ends of the sealing sleeve 5, sealing the connection between the fire hydrant body 1 and the connecting pipe 4, as well as between the connecting pipe 4 and the sleeve 6. This improves the sealing performance of the connecting pipe 4 after installation, ensuring no leakage during use, achieving reliable sealing of outdoor fire-fighting equipment in extreme environments, and effectively improving the stability and durability of the equipment.

[0036] Example 2

[0037] like Figure 1-2 As shown, the sealing device for outdoor fire-fighting equipment proposed in this utility model differs from that in Embodiment 1 in that the outer side of the sleeve 6 is provided with an external thread 9, and the inner side of the connecting sleeve 2 is provided with a threaded groove 8. When the connecting sleeve 2 and the fire hydrant body 1 are installed together, the external thread 9 is accommodated in the threaded groove 8.

[0038] In an optional embodiment, a handle 3 is provided on the outer side of the connecting sleeve 2, and the number of handles 3 is at least one.

[0039] In an optional embodiment, a connecting groove 10 is provided at the middle of one end of the handle 3.

[0040] In this embodiment, the connection between the connecting sleeve 2 and the sleeve 6 is made more convenient by the cooperation of the threaded groove 8 and the external thread 9. The connection stability between the connecting sleeve 2 and the handle 3 is improved by setting a handle 3 on the outside of the connecting sleeve 2 so that the handle 3 can drive the connecting sleeve 2 to rotate. The connection stability between the connecting sleeve 2 and the handle 3 is further improved by setting a connecting groove 10 at the end of the handle 3 so that the tool can be inserted into the connecting groove 10 for use.

[0041] Example 3

[0042] like Figure 3-4 As shown, the sealing device for outdoor fire-fighting equipment proposed in this utility model differs from that in Embodiment 1 in that a connecting ring 7 is provided at the end of the connecting pipe 4 and inside the connecting sleeve 2, and the connecting ring 7 is arranged to match the size of the connecting sleeve 2.

[0043] In an optional embodiment, a slot 12 is provided on the inner side of the end of the sleeve 6, and a block 13 is provided on the side of the connecting ring 7. The block 13 is inserted into the slot 12, and the size of the block 13 and the slot 12 are matched.

[0044] In this embodiment, by setting a connecting ring 7 on the outside of the connecting pipe 4, when the connecting sleeve 2 is connected to the sleeve 6, the connecting ring 7 drives the connecting pipe 4 to move towards the sleeve 6, so that the connecting pipe 4 and the connecting ring 7 respectively squeeze one end of the sealing sleeve 5. At the same time, the rotation of the connecting pipe 4 is limited by the cooperation of the slot 12 and the block 13, so as to prevent the connecting pipe 4 from rotating with the connecting sleeve 2.

[0045] Example 4

[0046] like Figure 3 As shown, the sealing device for outdoor fire-fighting equipment proposed in this utility model differs from that in Embodiment 1 in that the sealing sleeve 5 includes a first gasket 51, an mounting sleeve 52, and a second gasket 55.

[0047] The mounting sleeve 52 is fitted onto the outer side of the end of the connecting pipe 4 and is located on the inner side of the sleeve 6, and is movably connected to the inner wall of the sleeve 6.

[0048] The second gasket 55 is disposed between the connecting pipe 4 and the outlet of the fire hydrant body 1 and is connected to one end of the mounting sleeve 52, and has a through hole in the middle.

[0049] The first gasket 51 is disposed between the sleeve 6 and the connecting ring 7 and is connected to the other end of the mounting sleeve 52.

[0050] In this embodiment, by placing the mounting sleeve 52 on the outside of the connecting pipe 4, and placing the first gasket 51 and the second gasket 55 between the end of the connecting ring 7 and the end of the sleeve 6, and between the outlet of the fire hydrant body 1 and the end of the connecting pipe 4, when the connecting pipe 4 is connected to the fire hydrant body 1, the first gasket 51 and the second gasket 55 are squeezed, which seals the connection between the connecting pipe 4 and the sleeve 6 and between the fire hydrant body 1 and the connecting pipe 4, resulting in a better sealing effect.

[0051] Example 5

[0052] like Figure 3 As shown, the sealing device for outdoor fire-fighting equipment proposed in this utility model differs from that in Embodiment 1 in that multiple convex rings 11 are arranged at equal intervals on the outer side of the end of the connecting pipe 4 and on the inner side of the sleeve 6, and multiple sealing grooves 54 are provided on the inner side of the mounting sleeve 52. When the mounting sleeve 52 and the connecting pipe 4 are installed together, the convex rings 11 are accommodated in the sealing grooves 54.

[0053] In an optional embodiment, a plurality of sealing rings 53 that are movably connected to the inner wall of the sleeve 6 are arranged at equal intervals on the outer side of the mounting sleeve 52.

[0054] In this embodiment, the cooperation between the sealing groove 54 and the convex ring 11, and the multiple sealing rings 53 provided on the outside of the mounting sleeve 52, form a stable sealing structure between the outer wall of the connecting pipe 4 and the inner wall of the sleeve 6 and the inner and outer walls of the mounting sleeve 52, which effectively improves the sealing performance and further enhances the sealing effect.

[0055] In this invention, the mounting sleeve 52 is fitted onto the outer side of the end of the connecting pipe 4, with the first gasket 51 located on the side of the connecting ring 7 and the second gasket 55 located at the end of the connecting pipe 4. The connecting pipe 4 is then inserted into the sleeve 6, with the second gasket 55 in contact with the fire hydrant body 1, the first gasket 51 in contact with the sleeve 6, and the sealing ring 53 in contact with the inner wall of the sleeve 6. This seals the outer wall of the mounting sleeve 52 and the inner wall of the sleeve 6. Simultaneously, the sealing groove 54, in cooperation with the protruding ring 11, ensures a sealed connection between the outer wall of the connecting pipe 4 and the inner wall of the mounting sleeve 52, making the mounting sleeve 52 more securely installed on the outer side of the connecting pipe 4. The connecting sleeve 2 is rotated outside the connecting pipe 4 by the handle 3. At the same time, the connecting sleeve 2 is connected to the sleeve 6 by the engagement of the threaded groove 8 and the external thread 9. The connecting sleeve 2 moves towards the fire hydrant body 1 outside the sleeve 6. Meanwhile, the connecting sleeve 2 moves the connecting pipe 4 towards the fire hydrant body 1 through the connecting ring 7. The connecting pipe 4 and the connecting ring 7 squeeze the second gasket 55 and the first gasket 51 respectively, so that the sleeve 6 and the connecting ring 7, as well as the fire hydrant body 1 and the connecting pipe 4, are sealed. This gives the connection between the fire hydrant body 1 and the connecting pipe 4 a triple sealing effect, ensuring that no leakage occurs during use.

[0056] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
