The connecting head 2 is provided with a second inner ring 5, and the connecting pipe 1 is provided with a plurality of steel balls 9 (GCr15 bearing steel, HRC 58-62), which are used to cooperate with the annular clamping groove 10 in the connecting head 2 to realize the clamping of the connecting pipe 1 and the connecting head 2.

[0043] Referring to Figures 3-5The clamping structure comprises a plurality of guide rods 6 fixed to the inner wall of the connecting head 2 away from the fixed pipe 3 and a first inner ring 4. The connecting pipe 1 is provided with a plurality of mounting grooves 8, and a steel ball 9 is arranged in each mounting groove 8. The inner wall of the connecting head 2 is provided with an annular clamping groove 10, and the annular clamping groove 10 is clamped and matched with the steel ball 9. One end of each of the plurality of guide rods 6 extends into the second inner ring 5, the outer wall of the guide rod 6 is sleeved with a first spring 7, and the two ends of the first spring 7 are fixedly connected with one side of the second inner ring 5 and the inner wall of one side of the connecting head 2 through spring seats. The stiffness coefficient of the first spring 7 ranges from 50 N / m to 150 N / m, so as to ensure that when the connecting pipe 1 is inserted into the connecting head 2, the second inner ring 5 can stably push the steel ball 9 to move outward and be clamped into the annular clamping groove 10.

[0044] Referring to Figures 3-5 , the second inner ring 5 is slidably sleeved on the outer wall of the first inner ring 4, and the outer wall of the second inner ring 5 is in contact with the inner wall of the connecting pipe 1. A rubber annular stopper 11 (fluorine rubber material) is fixed in the connecting pipe 1, and the rubber annular stopper 11 is used for limiting the second inner ring 5 and increasing the sealing property between the second inner ring 5 and the inner wall of the connecting pipe 1. The thickness of the rubber annular stopper 11 ranges from 2 mm to 5 mm, and the material is high-elasticity rubber, so as to ensure good sealing effect.

[0045] Referring to Figure 3 , Figure 4 and Figure 8 , the locking structure is used for limiting the second inner ring 5, so as to avoid that the second inner ring 5 moves towards the fixed pipe 3 under the condition of external force error. The locking structure comprises a plurality of fixed rods 12 fixed to the inner wall of the connecting pipe 1 and a lifting plate 13 slidably arranged on the outer wall of the fixed rod 12. The outer wall of the fixed rod 12 is sleeved with a tension spring 15, and the two ends of the tension spring 15 are fixedly connected with the lifting plate 13 and the inner wall of the connecting pipe 1 through spring seats. The stiffness coefficient of the tension spring 15 ranges from 30 N / m to 100 N / m, so as to ensure that the lifting plate 13 can tightly abut against the inner wall of the second inner ring 5. The side of the lifting plate 13 close to the connecting head 2 is fixed with a trapezoidal clamping block 16, the inner wall of the second inner ring 5 is provided with an annular positioning groove 17, the trapezoidal clamping block 16 is clamped and matched with the annular positioning groove 17, and the trapezoidal clamping block 16 is used for limiting the second inner ring 5.

[0046] Specifically, when the second inner ring 5 extends into the connecting pipe 1 and pushes the steel ball 9 to move, the trapezoidal clamping block 16 is clamped into the annular positioning groove 17 under the action of the pulling force of the tension spring 15, and the cooperation between the trapezoidal clamping block 16 and the annular positioning groove 17 can limit the second inner ring 5, so as to avoid that the second inner ring 5 moves towards the fixed pipe 3 under the action of water pressure.

[0047] Referring to Figure 2 , Figure 3 and Figure 7, the dismounting structure is used for facilitating quick dismounting between the connecting pipe 1 and the connecting head 2.

The stopper 19 is internally provided with an inclined groove 20, the inclined groove 20 is slidingly connected with a first pin rod 21, and the first pin rod 21 is fixed in the H-shaped plate 22. The top end of the H-shaped plate 22 extends to the outside of the connecting head 2, the top of the connecting head 2 is rotationally connected with a rotating plate 23 through a base, the rotating plate 23 is internally provided with a let-in groove 24, the let-in groove 24 is slidingly connected with a second pin rod 25, and the second pin rod 25 is fixed in the H-shaped plate 22. The top of the connecting head 2 is fixed with a second spring 26 through a spring base, and the top end of the second spring 26 is fixedly connected with the bottom of the rotating plate 23 through the spring base. The stiffness coefficient of the second spring 26 ranges from 20 N / m to 80 N / m, so as to ensure that the rotating plate 23 can be automatically reset after being pressed.

[0048] Specifically, by pressing the rotating plate 23, the rotating plate 23 drives the H-shaped plate 22 to move upwards through the second pin rod 25, the H-shaped plate 22 drives the stopper 19 and the second inner ring 5 to move towards the fixed pipe 3 through the cooperation of the first pin rod 21 and the inclined groove 20, so as to release the brake of the second inner ring 5 on the steel ball 9, and then the dismounting of the connecting pipe 1 and the connecting head 2 can be quickly completed.

[0049] Referring to Figures 1-4 and Figure 9 , the driving structure is used for releasing the locking of the second inner ring 5 by the locking structure. The driving structure comprises a rotating ring 27 rotating at one end of the connecting head 2, and a plurality of second magnets 28 and third magnets 30 are fixedly embedded in the inner wall of the rotating ring 27. The side close to the connecting head 2 of the lifting plate 13 is fixed with a first magnet 14 (neodymium iron boron N35 grade magnet), and magnetic attraction force is generated between the first magnet 14 and the second magnet 28, which is used to increase the pressing force of the lifting plate 13 on the second inner ring 5, so as to ensure the brake of the second inner ring 5. Repulsion force is generated between the third magnet 30 and the first magnet 14, which is used to drive the lifting plate 13 and the trapezoidal clamping block 16 to move, so that the trapezoidal clamping block 16 is separated from the annular positioning groove 17, and the dismounting structure is convenient to operate in the later stage. The repulsion force between the third magnet 30 and the first magnet 14 is greater than the pulling force of the tension spring 15.

[0050] Referring to Figure 9 , a plurality of first indicating plates 29 and second indicating plates 31 are fixed to one side of the rotating ring 27, the plurality of first indicating plates 29 correspond to the plurality of second magnets 28 in position, and the plurality of second indicating plates 31 correspond to the plurality of third magnets 30 in position. The top of the connecting head 2 is fixed with an indicating mark 32, the indicating mark 32 cooperates with the adjacent first magnet 14, and the indicating mark 32 cooperates with the second indicating plate 31 and the first indicating plate 29, which is used to determine that the third magnet 30, the second magnet 28 and the first magnet 14 correspond in position through the second indicating plate 31 and the first indicating plate 29.

[0051] Specifically, rotating the rotating ring 27, through the magnetic attraction force between the second magnet 28 and the first magnet 14, the lifting plate 13 can be tightly attached to the inner wall of the second inner ring 5, so that the trapezoidal clamping block 16 is stably positioned to the second inner ring 5. In order to be able to release the brake of the trapezoidal clamping block 16 to the second inner ring 5, rotate the rotating ring 27, the third magnet 30 is aligned with the first magnet 14, the repulsion between the third magnet 30 and the first magnet 14 pushes the lifting plate 13 to move, and the trapezoidal clamping block 16 is separated from the annular positioning groove 17, which is convenient for driving the second inner ring 5 to move to the fixed tube 3 direction in the later stage.

[0052] With reference to Figure 3 , Figure 4 and Figure 8 , the end of the lifting plate 13 away from the fixed tube 3 is fixed with a beveled flow guide plate 18, one end of the beveled flow guide plate 18 abuts against the inner wall of the connecting pipe 1. When the water flows through, the extrusion of the water flow to the beveled flow guide plate 18 can further increase the clamping of the lifting plate 13 to the second inner ring 5. The side of the rubber annular baffle 11 away from the second inner ring 5 is provided with a slope, which is used to reduce the impact force of the water flow to the second inner ring 5, and avoid the water flow driving the second inner ring 5 to move.

[0053] With reference to Figure 1 and Figure 2 , the ball valve core 33 is sealingly and rotatably connected in the connecting pipe 1, which is used to control the opening and closing of the connecting pipe 1. The top of the ball valve core 33 is fixed with a rotating rod 34, the top end of the rotating rod 34 is sealingly and rotatably penetrated through the connecting pipe 1 and extends above the connecting pipe 1, and the top end of the rotating rod 34 is fixed with a rotating disc 35. By rotating the rotating disc 35, the ball valve core 33 can be driven to rotate, thereby controlling the opening and closing of the connecting pipe 1.

[0054] With reference to Figures 8-10 , the conversion joint comprises the above-mentioned locking assembly, and further comprises a limiting ring 41 fixed on the outer wall of the fixed tube 3. The end of the connecting head 2 away from the connecting pipe 1 is fixed with a plurality of L-shaped clamping blocks 42, and the limiting ring 41 is located in the plurality of L-shaped clamping blocks 42. The limiting ring 41 and the L-shaped clamping blocks 42 are matched to limit the fixed tube 3, thereby increasing the stability between the fixed tube 3 and the connecting head 2.

[0055] With reference to Figure 1 , Figure 2 and Figure 10 , the hollow universal ball 38 is sealingly and rotatably connected in the fixed tube 3, the side of the hollow universal ball 38 close to the connecting pipe 1 is provided with a liquid inlet 40, and the other side of the hollow universal ball 38 is fixedly connected with a mounting sleeve 39. The mounting sleeve 39 is connected with the fire hose under pressure, and the connecting head 2 is made of aluminum-magnesium alloy to reduce the overall weight.

[0056] With reference to Figure 1 , Figure 2 and Figure 10When the fire pressure water belt is connected with the mounting sleeve 39, the angle of the mounting sleeve 39 can be adjusted through the cooperation of the mounting sleeve 39, the hollow universal ball 38 and the fixed pipe 3, so that the fire pressure water belt can be sprayed conveniently. The rupture of the connection position between the mounting sleeve 39 and the fire pressure water belt can be avoided when the fire pressure water belt is sprayed at different angles in the later period.

[0057] In another embodiment, referring to Figure 3 、 Figure 6 and Figure 7 , the outer wall of the second inner ring 5 is fixedly sleeved with a fixed stop ring 36, one side of the fixed stop ring 36 is fixedly connected with one side of the plurality of stop blocks 19. The side of the fixed stop ring 36 away from the stop blocks 19 is fixedly connected with a sealing rubber ring 37 abutting against one end of the connecting pipe 1. When the connecting pipe 1 and the connecting head 2 are butted, the sealing property between the connecting pipe 1 and the second inner ring 5 can be increased through the cooperation of the fixed stop ring 36 and the sealing rubber ring 37. The thickness of the sealing rubber ring 37 ranges from 3mm to 6mm, and the material is high-elasticity rubber, so as to ensure good sealing effect.

[0058] The use method of the light-weight fire pressure water belt conversion joint comprises the following steps:

[0059] S1, the connecting head 2 is sleeved on the outer wall of the connecting pipe 1, and when the connecting head 2 is inserted into the connecting pipe 1, the first inner ring 4 and the second inner ring 5 are inserted into the connecting pipe 1, and the cooperation of the second inner ring 5 and the steel ball 9 drives the steel ball 9 to move outward, and the steel ball 9 just extends into the annular clamping groove 10. At this time, the cooperation of the second inner ring 5 and the annular clamping groove 10 can limit the steel ball 9, and the cooperation of the steel ball 9, the annular clamping groove 10 and the mounting groove 8 can easily and quickly fix the connecting pipe 1 and the connecting head 2;

[0060] S2, when the second inner ring 5 extends into the connecting pipe 1 and pushes the steel ball 9 to move, the trapezoidal clamping block 16 is clamped into the annular positioning groove 17 under the action of the tension of the tension spring 15.
