[0022] See also Figure 1-5 , a galvanized square pipe that can be bent and connected, including a first pipe body 1 and a butt joint 6, a bending structure 2 is installed on the top edge of the first pipe body 1, and a second pipe body 3 is arranged above the bending structure 2, the first pipe body 1 is rotatably connected to the second pipe body 3 through the bending structure 2, and the rotation angle range of the bending structure 2 is 0° to 180°, this setting allows the first pipe body 1 and the second pipe body 3 to be bent, which is convenient for cleaning the inside of the pipeline, and secondly, the pipeline is bent for transportation, a limiting groove 4 is arranged on the cross-section of the second pipe body 3, a sealing strip 5 adapted to the limiting groove 4 is arranged on the cross-section of the first pipe body 1, and the sealing strip 5 and the limiting groove 4 are arranged at the connection between the first pipe body 1 and the second pipe body 3, and the outer surface of the sealing strip 5 is in contact with the inner surface of the limiting groove 4, and the gap at the connection between the first pipe body 1 and the second pipe body 3 is filled by the mutual cooperation of the sealing strip 5 and the limiting groove 4, thereby improving the sealing of the connection between the first pipe body 1 and the second pipe body 3 and reducing the probability of pipeline leakage;
[0023] The docking joint 6 is fixed to the left and right sides of the first tube body 1. The docking joint 6 includes two side plates 601, and a slide groove 602 is provided inside the side plate 601. A slider 603 is installed inside the slide groove 602, and a movable plug plate 604 is fixed to the end of the slider 603 away from the side plate 601. The slider 603 is set to a "T"-shaped structure. This setting allows the slider 603 to slide stably inside the slide groove 602 to prevent the slider 603 from escaping from the slide groove 602. Therefore, the movable plug plate 604 slides stably on the outside of the side plate 601. A cavity 605 is provided inside the movable plug plate 604, and one end of a spring 606 is installed on the inner wall of the cavity 605. A clamping block 607 is connected to the other end of the spring 606. A groove 608 is provided on the surface of the movable plug plate 604, and a protrusion 609 is integrally provided on the surface of the movable plug plate 604. The setting of the spring 606 makes the clamping block 607 retractable, and the clamping block 607 penetrates the movable plug plate 604 through the groove 608. The movable plug plate 604 and the setting of the protrusion 609 are convenient for the staff to push the movable plug plate 604.

Pressing the block 607 causes the spring 606 to contract, pushing the movable plug plate 604 to approach the fixed block 701 until the front end of the movable plug plate 604 passes through the fixed block 701. The spring 606 without pressure is reset, pushing the block 607 to pass through the groove 608, and the block 607 is against the fixed block 701, so that the docking seat 7 and the docking head 6 are fixed. In this way, the assembly of the first tube body 1 and the second tube body 3 is realized without the help of external tools, and it is convenient and quick to use.
[0024] Working principle: When transporting the pipeline, the first tube body 1 and the second tube body 3 can be bent to shorten the length for easy transportation. When in use, the cross-section of the first tube body 1 and the cross-section of the second tube body 3 are integrated through the bending structure 2. At this time, the sealing strip 5 is inserted into the limiting groove 4. The sealing strip 5 and the limiting groove 4 cooperate with each other to improve the sealing of the connection between the first tube body 1 and the second tube body 3. Since the movable plug plate 604 is slidably connected to the outer side of the side plate 601 through the sliding groove 602 and the slider 603, the finger is pushed against the protrusion 609 to push The movable plug plate 604 approaches the fixed block 701, and at the same time presses the block 607 to shrink the spring 606 until the front end of the movable plug plate 604 passes through the fixed block 701 through the passage groove 702. At this time, the slider 603 moves to the end of the slide groove 602, and the spring 606 without pressure is reset, pushing the block 607 to pass through the groove 608. The block 607 abuts against the fixed block 701, so that the docking seat 7 and the docking head 6 are fixed. In this way, the first tube body 1 and the second tube body 3 are assembled without the help of external tools, which is convenient and quick to use.
