[0004] A quick-release fire-fighting pipeline interface includes a first connecting pipe and a second connecting pipe, which are connected by a connecting structure.

[0005] The connecting structure includes a fixing ring, a rotating block, a pressing block, an ear block, and a limiting part. The fixing ring is fixedly connected to one end of the first connecting tube, and the second connecting tube can be inserted into the fixing ring. Symmetrical ear blocks are fixedly arranged on the circumferential surface of the fixing ring. One end of the limiting part is rotatably connected to each ear block. The fixing ring is provided with a square opening corresponding to the position of the ear block. The end of the limiting part can pass through the square opening and engage with the annular groove opened on the second connecting tube.

[0007] Furthermore, the limiting groove includes a limiting hole formed on the rotating block and a slot formed at the edge of the rotating block. The slot is connected to one end of the corresponding limiting hole, and the slot and the limiting hole are arranged in an L-shape.

[0008] Furthermore, the width of the limiting hole is greater than the width of the limiting part, the length of the limiting hole is greater than the length of the limiting part in the first direction, and the limiting part can pass through the slot and enter the limiting hole.

[0009] Furthermore, a pressure block is provided on the rotating block, and the pressure block is screwed to the first connecting ring.

[0010] Furthermore, the upper end of the limiting part is a handle extending away from the axis of the rotating block.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] The quick-release fire-fighting pipe interface includes a first connecting pipe 1 and a second connecting pipe 6, which are connected by a connecting structure.

[0025] The connecting structure includes a fixing ring 5, a rotating block 4, a pressing block 3, an ear block 7, and a limiting part 8. The fixing ring 5 is fixedly connected to one end of the first connecting tube 1. The second connecting tube 6 can be inserted into the fixing ring 5. The circumferential surface of the fixing ring 5 is fixedly provided with symmetrical ear blocks 7. One end of the limiting part 8 is rotatably connected to each ear block 7. The fixing ring 5 is provided with a square opening 501 corresponding to the position of the ear block 7. The end of the limiting part 8 can pass through the square opening 501 and engage with the annular groove 12 opened on the second connecting tube 6.

[0026] The rotating block 4 is rotatably connected to the first connecting ring 2. The first connecting ring 2 is fixed by a ring 5 and fitted onto the first connecting tube 1. One side of the rotating block 4 abuts against the fixed ring 5. The rotating block 4 is provided with a limiting groove corresponding to the position of the limiting part 8. The limiting groove can accommodate the limiting part 8.

[0027] In this embodiment, the first connecting pipe 1 and the second connecting pipe 6 should be fixed to one end of the two flexible tubes respectively.

[0028] The limiting groove includes a limiting hole 11 formed on the rotating block 4 and a slot 10 formed at the edge of the rotating block 4. The slot 10 is connected to one end of the corresponding limiting hole 11, and the slot 10 and the limiting hole 11 are arranged in an L-shape.

[0029] The width of the limiting hole 11 is greater than the width of the limiting part 8, and the length of the limiting hole 11 is greater than the length of the limiting part 8 in the first direction. The limiting part 8 can pass through the slot 10 and enter the limiting hole 11.

[0030] The rotating block 4 is provided with a pressure block 3, which is screwed to the first connecting ring 2.

[0031] In this embodiment, the rotating pressure block 3 can press the rotating block 4 tightly to prevent it from loosening.

[0032] The upper end of the limiting part 8 is a handle 802 extending away from the axis of the rotating block 4. A stop block 801 is fixedly provided on one side of the upper end of the limiting part 8 corresponding to the other end of the limiting hole 11. The stop block 801 can abut against the other end of the limiting hole 11 provided on the rotating block 4. The lower side of the handle 802 is a first abutting surface 803. The first abutting surface 803 is an inclined surface. The first abutting surface 803 can contact the upper side of the rotating block 4. The side of the limiting part 8 away from the axis of the rotating block 4 is a second abutting surface 804. The second abutting surface 804 can abut against the side of the limiting hole 11 provided on the rotating block 4 away from the axis.

[0033] The lower end of the limiting part 8 is an inwardly extending arc-shaped pressing part 13 corresponding to the position of the square opening 501. The pressing part 13 can pass through the square opening 501. An annular groove 12 is provided on the circumferential surface of one end of the second connecting tube 6. The pressing part 13 can be engaged with the annular groove 12.

[0034] In this embodiment, the second connecting tube 6 is inserted into the fixing ring 5, and the limiting part 8 is rotated so that the pressing part 13 of the limiting part 8 passes through the square opening 501 and engages with the annular groove 12 on the second connecting tube 6.

[0035] At this time, the rotating block 4 can be in three positions. In the first position, the rotating block 4 is rotated so that the slot 10 of the rotating block 4 corresponds to the limiting part 8, which facilitates the opening and closing of the limiting part 8. The limiting part 8 can be easily inserted into the slot 10 and can also be easily pulled out of the slot 10, which can achieve quick operation. The rotating block 4 plays a certain protective role.

[0036] In the second position, after the limiting part 8 is inserted into the slot 10, the rotating block 4 is rotated so that the limiting part 8 enters the limiting groove of the rotating block 4. The abutment 801 of the limiting part 8 abuts against one end of the limiting hole 11, the first abutment surface 803 contacts the upper side of the rotating block 4, and the second abutment surface 804 abuts against the side of the limiting hole 11 away from the axis, thereby achieving all-round limiting of the limiting part 8, thus stably connecting the first connecting pipe 1 and the second connecting pipe 6. At this time, the limiting part 8 is locked by the rotating block 4, and the limiting block cannot be opened by collision, accidental touch or other operations.

[0037] In the third position, the limiting part 8 is inserted into the slot 10. Rotating the rotating block 4 makes the slot 10 not correspond to the limiting part 8, so that the limiting part 8 cannot be inserted into the slot 10, which facilitates the insertion of the first connecting pipe 1 and the second connecting pipe 6.

[0038] The method of using this utility model is as follows: Align the second connecting tube 6 with the fixing ring 5 and insert it into the fixing ring 5. Rotate the handle 802 of the limiting part 8 so that the pressing part 13 at the lower end of the limiting part 8 passes through the square opening 501 and is inserted into the annular groove 12 of the second connecting tube 6. Select the position of the adjusting rotating block 4 as needed and adjust the position of the limiting part 8 to complete the connection of the first connecting tube 1 and the second connecting tube 6.

[0039] The above-disclosed embodiments are merely specific examples of this utility model. However, this utility model is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
