DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0032] See also Figure 1-7 As shown, the utility model is a fire-fighting joint structure, comprising a fire-fighting pipe fitting 1 and a main pipe fitting 2 connected to one side of the fire-fighting pipe fitting 1, and further comprising:

[0033] A connecting pipe 3 is connected to one end of the main pipe 2. A connecting protrusion 4 is provided inside the connecting pipe 3 and is embedded in the connecting pipe 3. A locking mechanism is provided at the end of the main pipe 2 away from the fire pipe 1 and is used to limit the position of the connecting pipe 3. A connecting groove 5 is provided on the inner side of the main pipe 2. The connecting groove 5 is stepped and engages with the connecting protrusion 4. The connecting protrusion 4 provided on one side of the connecting pipe 3 can be slidably embedded in the connecting groove 5, thereby connecting the main pipe 2 and the connecting pipe 3 to prevent the connecting pipe 3 from deflecting. A limiting groove 6 is provided on the inner wall of the connecting groove 5 and the connecting protrusion 4. A sealing gasket 7 is embedded in the limiting groove 6.

[0034] The sealing gasket 7 can be embedded in the limiting groove 6, and the sealing gasket 7 can avoid the formation of a gap at the connection between the main pipe 2 and the connecting pipe 3, which would cause a poor sealing effect between the main pipe 2 and the connecting pipe 3 and affect the subsequent water transportation. The cross section of the limiting groove 6 is a trapezoidal structure. Two sets of sealing gaskets 7 are provided, and are respectively engaged with the limiting groove 6;

[0035] By setting the limiting groove 6 to be a trapezoidal structure, the sealing gasket 7 can be prevented from being deflected when being engaged with the sealing gasket 7 .

[0036] Since multiple sets of sealing gaskets 7 are provided, the sealing effect between the main pipe 2 and the connecting pipe 3 can be improved;

[0037] The locking mechanism includes a locking groove 8, a locking rail 9 and a locking card 10. The locking grooves 8 are evenly arranged on the side of the connecting pipe 3 close to the main pipe 2, and the cross-section of the locking groove 8 is a fan-shaped structure. The locking rail 9 is arranged on one side of the locking groove 8. The locking card 10 is fixed on one side of the main pipe 2, and the locking card 10 is slidably engaged with the inside of the locking groove 8 and rotates to slide on the inside of the locking rail 9.

[0038] The locking groove 8 can be set on the outer side of the locking clamp 10, and then, when the connecting pipe 3 is rotated counterclockwise, the locking clamp 10 can be rotated and clamped on the inner side of the locking track 9, so that the locking clamp 10 can be embedded in the connecting pipe 3, which is convenient for subsequent processing;

[0039] The limiting mechanism is sleeved on the outer surface of the connecting pipe 3 to ensure the connection between the main pipe 2 and the connecting pipe 3. The limiting mechanism includes a positioning protrusion 11, a fixing sleeve 12 and a locking groove 15. The positioning protrusion 11 is evenly fixed to the inner wall of the main pipe 2, the fixing sleeve 12 is sleeved on the outer surface of the connecting pipe 3, and the locking groove 15 is provided on the inner side of the fixing sleeve 12 and is engaged with the positioning protrusion 11.

[0040] The fixed sleeve 12 can be pulled outward, and when the fixed sleeve 12 is pulled outward, the locking mechanism can be completed for connection. When the connection is completed, the fixed sleeve 12 can be pushed to one side, so that the locking groove 15 on one side of the fixed sleeve 12 can be engaged with the outer side of the positioning protrusion 11, thereby preventing the fixed sleeve 12 from deflecting and shaking, thereby facilitating subsequent handling of the fixed sleeve 12; the cross section between the positioning protrusion 11 and the locking groove 15 is an arc-shaped structure;

[0041] Since both are in an arc shape, the connection between the fixed sleeve 12 and the main pipe 2 can be ensured, thereby facilitating subsequent processing;

[0042] The inner wall of the fixed sleeve 12 is evenly provided with reset grooves 13, and a reset spring 14 is fixed inside the reset groove 13, and the other end of the reset spring 14 is in contact with the connecting pipe 3. The reset groove 13 can limit the reset spring 14 to prevent the reset spring 14 from being offset, and one side of the reset spring 14 can be connected to the connecting pipe 3, so that when the fixed sleeve 12 is loosened, the fixed sleeve 12 can be automatically reset, so that the locking groove 15 on one side of the fixed sleeve 12 can be engaged with the positioning protrusion 11.

[0043] A connecting thread 16 is fixed to the outer surface of the fixed sleeve 12, and a connecting sleeve 17 is sleeved on the outer surface of the main pipe 2, and the connecting sleeve 17 is connected to the connecting thread 16. When the fixed sleeve 12 is connected and locked, the connecting sleeve 17 can be rotated so that the connecting sleeve 17 can be screwed onto the connecting thread 16 on the surface of the fixed sleeve 12, thereby locking the fixed sleeve 12, thereby ensuring the connection effect between the main pipe 2 and the connecting pipe 3, and avoiding the use of clamps or bolts to connect, which affects the connection efficiency of the joint.

[0044] The above are only preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions described in the aforementioned embodiments, any equivalent replacement of some of the technical features therein, and any modification, equivalent replacement, and improvement made are within the scope of protection of the present invention.
