[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) The pipe fixing connector with mutual locking function, when connecting and fixing the first pipe and the second pipe, firstly, the connecting ring is placed between the first pipe and the second pipe, and the two locking rings are placed on the outer surfaces of the first pipe and the second pipe respectively, and the two locking rings are locked, and then the locking assembly is used to drive the first pipe and the second pipe to approach each other. When the first pipe and the second pipe approach each other, the limiting block cooperates with the limiting rod to limit the movement trajectory to avoid deviation after approaching, and when the two locking rings are not close to each other, they are limited by the limiting plate to avoid the locking ring and the limiting rod from being separated. Through the above structure, when the first pipe and the second pipe are connected and fixed, not only can they be locked by the connecting ring, but also the first pipe and the second pipe can be tightened with the help of the two locking rings to avoid the problem of gap at the connection, which leads to the problem of reduced overall sealing performance.

At the same time, the contact friction between the contact plate and the upper surface of the locking block can be used to prevent the control block from rotating. In addition, since the two locking rings are connected to the bidirectional threaded rod, they restrict and lock each other, thereby improving the overall locking strength.

When the first pipe 3 and the second pipe 4 approach each other, the movement trajectory is limited by the limit block 7 and the limit rod 8 to avoid deviation after approaching, and when the two locking rings 2 are not close to each other, they are limited by the limit plate 9 to avoid the locking ring 2 and the limit rod 8 from being separated. Through the above structure, when the first pipe 3 and the second pipe 4 are connected and fixed, not only can they be locked by the connecting ring 1, but the first pipe 3 and the second pipe 4 can also be tightened with the help of the two locking rings 2 to avoid gaps in the connection, which leads to the problem of reduced overall sealing performance.

[0024] Furthermore, the locking assembly includes a bidirectional threaded rod 10, which is rotatably sleeved inside the locking block 5, and the two ends of the bidirectional threaded rod 10 are respectively threaded through the opposite side surfaces of the two second locking blocks 6, and the two ends of the bidirectional threaded rod 10 are also fixedly connected to the limiting plate 9, the upper surface of the locking block 5 is rotatably connected with a control block 11, and the lower side surface of the control block 11 is fixedly connected with a driving rod 12, and the lower end of the driving rod 12 is rotatably penetrated into the interior of the locking block 5, and the lower end of the driving rod 12 is fixedly connected with a bevel gear 13, and the outer surface of the bidirectional threaded rod 10 is sleeved with a second bevel gear 14, and the bevel gear 13 meshes with the second bevel gear 14 The upper surface of the control block 11 is provided with a hexagonal groove 15, the outer surface of the control block 11 is provided with a threaded groove 16, the outer surface of the control block 11 is provided with a locking ring 17 through the threaded groove 16, the lower surface of the locking ring 17 is fixedly connected with a contact plate 18, the inner wall of the connecting ring 1 is provided with a mounting groove 19, the interior of the mounting groove 19 is provided with a sealing ring 20, the inner wall of the sealing ring 20 is provided with an arc groove 21, the inner wall of the sealing ring 20 is fixedly connected with a sealing ring 22, the outer surfaces of the connecting ring 1 and the locking ring 2 are both provided with openings, the outer surfaces of the connecting ring 1 and the locking ring 2 are respectively fixedly connected with two mounting plates 23, and the upper and lower mounting plates 23 are fixedly connected with the upper and lower mounting plates 23. The internal threaded sleeve is provided with a bolt 24, through which the two locking rings 2 are respectively locked on the outer surfaces of the first pipe 3 and the second pipe 4, and then the hexagonal tool is used to limit the control block 11 from rotating. At this time, the locking ring 17 drives the contact plate 18 to rise, and the contact between the contact plate 18 and the upper surface of the locking block 5 is released. Then, the control block 11 is rotated by the hexagonal tool. When the control block 11 rotates, the driving rod 12 is used to drive the bevel gear 13 to rotate synchronously. After the bevel gear 13 rotates, the second bevel gear 14 is driven to rotate synchronously. After the second bevel gear 14 rotates, the bidirectional threaded rod 10 is driven to rotate synchronously.

[0025] Working principle: when connecting and fixing the first pipe 3 and the second pipe 4, first place the connecting ring 1 between the first pipe 3 and the second pipe 4, and place the two locking rings 2 on the outer surfaces of the first pipe 3 and the second pipe 4 respectively, and lock the two locking rings 2, and use the bolts 24 to lock the two locking rings 2 on the outer surfaces of the first pipe 3 and the second pipe 4 respectively, and then use the locking assembly to drive the first pipe 3 and the second pipe 4 to approach each other. When the first pipe 3 and the second pipe 4 approach each other, the limiting block 7 cooperates with the limiting rod 8 to limit the movement trajectory to avoid deviation after approaching, and when the two locking rings 2 are not close to each other, they are limited by the limiting plate 9 to prevent the locking ring 2 from being separated from the limiting rod 8, and then use the hexagonal tool The tool restricts the control block 11 from rotating. At this time, the locking ring 17 drives the contact plate 18 to rise, and releases the contact between the contact plate 18 and the upper surface of the locking block 5. Then, the control block 11 is rotated by the hexagonal tool. When the control block 11 rotates, the driving rod 12 is synchronously used to drive the bevel gear 13 to rotate. After the bevel gear 13 rotates, the second bevel gear 14 is synchronously driven to rotate. After the second bevel gear 14 rotates, the bidirectional threaded rod 10 is synchronously driven to rotate. Since the movement trajectories of the two locking rings 2 are restricted, when the bidirectional threaded rod 10 rotates, the two locking rings 2 will be driven to approach each other, and the side surface of the first pipe 3 and the second pipe 4 close to each other will contact the sealing ring 22, and then the connecting ring 1 can be locked with the bolt 24.
