Brackets 6 are fixed at equal angles on the outer walls of the two ends of the connecting pipe 1, and a knob 7 is movably installed on the inner wall of the bracket 6. A stabilizing column 8 is movably provided on the inner wall of the knob 7, and a pressure plate 9 is fixedly connected to the end of the stabilizing column 8. At the same time, a non-slip rubber pad 10 is bonded to the surface of the pressure plate 9 away from the stabilizing column 8, and a limiting mechanism 13 is movably installed on the inner wall of the bracket 6 on the side of the knob 7.

[0022] The bracket 6 and the knob 7 are rotatably connected, and the knob 7 and the stabilizing column 8 are threadedly arranged, so that the user can rotate the knob 7 to move the stabilizing column 8 relative to the knob 7 .

[0023] A clamping rod 11 is fixed to the surface of the pressure plate 9 on both sides of the stabilizing column 8, and a clamping sleeve 12 is slidably installed on the outer wall of the clamping rod 11, and the clamping sleeve 12 is fixedly connected to the bracket 6, which is convenient for the movement of the stabilizing column 8, thereby driving the pressure plate 9 to move, so that the pressure plate 9 drives the anti-slip rubber pad 10 to fit tightly against the water pipe installed on the connecting pipe fitting 1, thereby improving the stability between the connecting device and the water pipe, and as the pressure plate 9 moves, the pressure plate 9 drives the clamping rod 11 to slide relative to the clamping sleeve 12, thereby facilitating the stable movement of the pressure plate 9.

[0024] The limiting mechanism 13 includes a limiting button 1301 and a tooth plate 1302, and the limiting button 1301 is movably installed on the inner wall of the bracket 6, and the end of the limiting button 1301 is movably provided with a tooth plate 1302, so as to limit the knob 7 through the limiting mechanism 13 to avoid the knob 7 from loosening when the device is working.

[0025] The limit button 1301 and the bracket 6 are threadedly connected, and the limit button 1301 and the tooth plate 1302 form a rotating structure, and the bracket 6 and the tooth plate 1302 form a sliding structure, so that the user can rotate the limit button 1301 to make the limit button 1301 move relative to the bracket 6, thereby driving the tooth plate 1302 to slide relative to the bracket 6.

[0027] Working principle: When using the water conservancy project pipeline connection device, first Figure 1-4 As shown, the inner walls at both ends of the connecting pipe 1 are respectively provided with internal threads. When using the device, the user inserts the water pipe with external threads on the outer wall of the end into the two ends of the connecting pipe 1 respectively, and then the user tightens the water pipe. At this time, the water pipe is close to the sealing ring 2, so that the water pipe is connected through the device, and then the user rotates the knob 7, and then the stabilizing column 8 moves relative to the knob 7. Next, the stabilizing column 8 drives the pressure plate 9 to move so that the anti-slip rubber pad 10 is close to the outer wall of the water pipe, and as the pressure plate 9 moves, the pressure plate 9 drives the clamping rod 11 to slide relative to the clamping sleeve 12, and then the user rotates the limit button 1301, and then the limit button 1301 moves relative to the bracket 6, and then the limit button 1301 pushes the tooth plate 1302 relative to the bracket 6 moves, and then with the continuous rotation of the limit button 1301, the tooth plate 1302 finally meshes with the gear 14, thereby limiting the gear 14 and the knob 7 to prevent the knob 7 from loosening when the device is in use. Similarly, the remaining knobs 7 and the limit mechanism 13 are operated, so that the anti-slip rubber pad 10 is squeezed by the pressure plate 9 to fit the water pipe, thereby improving the stability between the water pipe and the connecting device. Therefore, the stability between the device and the water pipe is improved, thereby avoiding the phenomenon of deviation between the water pipe and the connecting pipe when in use, thereby avoiding water pipe leakage, and improving the practicality of the device. Then the protective sleeve 4 and the protective rubber pad 5 protect the connecting pipe 1 to prevent the connecting pipe 1 from being damaged by external force collision.
