Technical Field

[0001] The utility model relates to the field of fire-fighting equipment, in particular to a fire-fighting pipe joint with quick docking. Background Technique

[0002] A fire truck is a special vehicle used to perform fire-fighting tasks. It can transport firefighters to the fire scene quickly and rescue at the fire scene. There are various fire-fighting appliances in the fire truck. When in use, the experience and proficiency of firefighters need to be tested to save time and provide valuable time for disaster relief. Therefore, various appliances in the fire truck require firefighters to practice and master them continuously. At the disaster relief scene of the fire source, the most important appliance is the docking and installation of pipes to use water to extinguish the fire source.

[0003] For the existing fire-fighting pipe joints, during the docking process, firefighters need to first dock and then twist in the latter two procedures to completely connect the pipes. During the docking process of the two pipes, there is no guiding function, and they need to be aligned before twisting, which affects the docking time. At the same time, there is a lack of a limiting device, and there is a risk of disconnection at the connection during the fire-fighting process. Content of the Utility Model

[0006] For further improvement of the above solution, annular grooves are arranged in both the first joint and the second joint, and sealing washers are arranged in the annular grooves.

[0007] For further improvement of the above solution, springs are arranged in the insertion blocks, the bottom ends of the telescopic rods are connected with the springs, and the front ends of the telescopic rods are smooth curved surfaces.

[0024] The preferred embodiments of the present utility model will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0025] A fire hose connector for quick docking, comprising a first connector 1 and a second connector 2. A first flange 3 is provided on the first connector 1, a second flange 4 is provided on the second connector 2, and a plurality of insertion blocks 5 are provided on the second flange 4. The insertion blocks 5 are L-shaped arc-shaped blocks with a wider outer width and a narrower inner width. Telescopic rods 6 are provided at the front ends of the insertion blocks 5. A plurality of chutes 7 cooperating with the insertion blocks 5 are provided in the first flange 3. The chutes 7 are arc-shaped grooves cooperating with the insertion blocks 5. A through hole 8 is provided in the first flange 3, and a limiting block 9 is provided in the chute 7. The insertion blocks 5 on the second flange 4 can play a guiding role. The staff inserts the insertion blocks 5 into the chutes 7 of the first flange 3, so that the first flange 3 and the second flange 4 are closely attached, and the telescopic rods 6 contract. Then rotate the second connector 2 until the telescopic rods 6 reach the through hole 8 and extend out. The telescopic rods 6 enter the through hole 8, so that the first connector 1 and the second connector 2 will not rotate relative to each other, and the limiting block 9 limits the insertion blocks 5 to achieve quick connection.

[0026] Wherein, annular grooves 10 are provided in both the first connector 1 and the second connector 2, and sealing washers 11 are provided in the annular grooves 10.

[0027] Wherein, a spring 12 is provided in the insertion block 5. The bottom end of the telescopic rod 6 is connected to the spring 12, and the front end of the telescopic rod 6 is a smooth curved surface. When the insertion block is inserted into the chute 7, the telescopic rod 6 contracts into the interior of the insertion block 5. When sliding a certain distance, the front end of the telescopic rod 6 automatically pops out and enters the through hole 8 to achieve quick connection.

[0028] Wherein, the inner diameter of the through hole 8 is the same as the outer diameter of the telescopic rod 6. The through hole 8 is a threaded hole, and a reset rod 13 is provided in the through hole 8. The reset rod 13 is a bolt rod, and the length of the reset rod 13 is the same as the length of the through hole 8. When it is necessary to disconnect the connection between the first connector 1 and the second connector 2, rotate the reset rod 13. The reset rod 13 rotates and pushes the telescopic rod 6 downward to contract into the insertion block 5. At this time, rotating the second flange 4 can complete the disassembly.

[0029] Wherein, the annular groove 10 is a space structure with a narrower outer width and a wider inner width, and the sealing washer 11 is an annular rubber ring with a narrower middle and wider ends. One side of the sealing washer 11 is arranged in the annular groove 10 of the second flange 4. When the first connector 1 and the second connector 2 are connected, the sealing washer 11 deforms, and the other side enters the annular groove 10 of the first flange 3 to ensure the sealing performance of the connection part.

[0030] Wherein, a handle 14 is provided on the second flange 4 to facilitate the staff to rotate the second flange 4.

[0031] Working principle:

[0032] The staff positions through the insertion block 5 and the sliding groove 7, inserting the insertion block 5 on the second flange 4 into the sliding groove 7 of the first flange 3. This makes the first flange 3 closely adhere to the second flange 4, and the telescopic rod 6 is squeezed by the inner wall of the sliding groove 7 and enters the jack. Then, the second flange 4 is rotated through the grip 14, causing the second flange 4 to rotate closely against the first flange 3 until the telescopic rod 6 enters the inside of the through hole 8. At the same time, the limit block 9 cooperates with the L-shaped insertion block 5 to complete the fixation, realizing the rapid docking of the first joint 1 and the second joint 2. When the insertion block 5 is inserted into the sliding groove 7, the first flange 3 and the second flange 4 closely squeeze the sealing gasket 11, and the sealing gasket 11 deforms and closely adheres to the inner wall of the annular groove 10 in the first flange 3 and the second flange 4, ensuring the sealing performance at the docking part of the first joint 1 and the second joint 2. When it is necessary to disassemble the first joint 1 and the second joint 2, rotate the reset rod 13. The reset rod 13 gradually enters the through hole 8 and pushes the telescopic rod 6 to contract into the insertion block 5, and then rotate the second flange 4 in the reverse direction to complete the disassembly.
