[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 The present invention provides an embodiment of a duct installation locking bracket, comprising a duct collar 1, a mounting plate on one side of the duct collar 1, and a connecting bolt on the top of the mounting plate for easy locking of the duct collar 1 and easy installation of the duct collar 1 on the outside of the duct. The top and bottom of the duct collar 1 are both hinged with first hinge rods 8, and a hinge frame 7 is hinged between the tops of the two sets of first hinge rods 8. The top of the hinge frame 7 is provided with an internal threaded tube, and the connecting plate 3 is adapted to the internal threaded tube. During the rotation of the external threaded rod 2, it can rotate along the internal threaded tube, which facilitates limiting the position of the external threaded rod 2. A second hinge rod 9 is hinged to one side of the first hinge rod 8. A hinge groove is provided on one side of the first hinge rod 8, and the second hinge rod 9 is located inside the hinge groove for easy installation of the second hinge rod 9.

[0022] The top of the hinge frame 7 is provided with an external threaded rod 2, the bottom of the external threaded rod 2 extends to the bottom of the hinge frame 7 and is provided with a slide rod 13, the outer side of the slide rod 13 is provided with a sleeve 12, and the two sides of the slide rod 13 are symmetrically provided with sliding plates. The top of the sleeve 12 is provided with a sliding hole, and the slide rod 13 and the sliding plate are both adapted to the sliding hole. During the rotation of the slide rod 13, it can drive the sleeve 12 to rotate, while not affecting the movement of the slide rod 13 along the sleeve 12. The bottom of the slide rod 13 is provided with a limiting plate, and the diameter of the limiting plate is larger than the diameter of the slider, so that the slide rod 13 can be drawn off.

[0023] The top of the movable plate 10 is provided with a bearing, and the bottom of the sleeve 12 is located inside the bearing, so that the sleeve 12 avoids rotating the movable plate 10 during rotation. The outside of the slide rod 13 is provided with a spring 11, which is located inside the sleeve 12. The bottom of the sleeve 12 is provided with the movable plate 10. The second hinge rod 9 is hinged to the movable plate 10.

[0024] Working principle: During installation, the duct is first connected and locked at the designated position, and other ducts are assembled. Then, two sets of duct collars 1 are connected to the outside of the two ducts in sequence. Then, the external threaded rod 2 is rotated upward. During the rotation of the external threaded rod 2, the sliding rod 13, the sleeve 12 and the moving plate 10 are pulled upward. When the moving plate 10 moves upward, it drives the second hinge rod 9 to flip. Then, during the flipping process, the second hinge rod 9 drives the first hinge rod 8 and the duct collar 1 to move, so that the two sets of duct collars 1 are brought closer to each other, thereby pressing the connection position of the two ducts. When the pressing reaches a certain limit, the duct collar 1 can no longer move. At this time, the external threaded rod 2 is rotated again. The external threaded rod 2 will drive the sliding rod 13 to move upward along the sleeve 12 and drive the spring 11 to compress. When the external threaded rod 2 moves to the designated position, the elastic collar 6 is hung on the outside of other pipes, thereby restricting the position of the duct collar 1.
