[0024] In order to adjust the angle of the connecting fixing frame 7, the rotating component 5 includes a connecting shaft 51. The left and right end faces of the connecting shaft 51 are respectively bearing connected to the left and right sides of the inner wall of the connecting seat 4 and near the top.

The top surfaces of the two fixing blocks 52 are respectively fixedly connected to the left and right sides of the bottom surface of the outer wall of the mounting seat 6.

[0025] In order to lock the connecting shaft 51 and prevent it from rotating after adjusting the angle of the connecting fixing bracket 7, locking gears 53 are fixedly sleeved on the left and right ends of the surface of the connecting shaft 51. Third screws 54 are threadedly connected to the left and right sides of the connecting seat 4 near the bottom.

Third rotating handles are fixedly connected to the end faces of the two third screws 54 away from each other.

[0026] In order to restrict the locking rack 55 so that it does not rotate with the third screw 54, the bottom inner surface of the connecting seat 4 is provided with a sliding groove 14 on both the left and right sides. The bottom surfaces of the two locking racks 55 are fixedly connected with sliders 56, and the two sliders 56 are slidably connected in the sliding grooves 14 on the left and right sides respectively.

[0027] To facilitate the fixing of HVAC pipes to the connecting bracket 7, the connecting bracket 7 includes a lower bracket 71. The top surface of the connecting block 8 is fixedly connected to the middle of the outer bottom surface of the lower bracket 71.

[0028] In order to restrict the movable block 11 so that it does not rotate with the first screw 10, the second guide rod 15 is fixedly connected to the left and right sides of the inner wall of the mounting base 6 near the bottom. The bottoms of the two movable blocks 11 are movably sleeved on the second guide rod 15.

[0029] Working principle: When using this utility model, all the connecting fixing brackets 7 have the same outer dimensions and shape, but the shape and size of the mounting groove can be designed in different styles. Therefore, the connecting fixing bracket 7 that matches the shape and size of the pipe can be selected to clamp pipes of different sizes and shapes. When it is necessary to replace the connecting fixing bracket 7, the first screw 10 can be turned by twisting the first handle. The rotation of the first screw 10 causes the two movable blocks 11 to move apart, so that the insert block 12 is pulled out from the slot 13, thereby releasing the fixation of the connecting block 8. Then the connecting fixing bracket is... Pull upwards 7 to remove the connecting block 8 from the mounting base 6, thus removing the connecting bracket 7. Then, select a connecting bracket 7 whose mounting slot matches the pipe, and insert the connecting bracket 7 into the top of the mounting base 6 through the connecting opening 9. Next, twist the first handle in the opposite direction to move the two insert blocks 12 towards each other and insert them into the slot 13, fixing the connecting block 8 in place. This completes the installation of the connecting bracket 7. Replacing the connecting bracket 7 is relatively convenient, reducing construction difficulty and time costs, and improving installation quality and efficiency. Place the pipe in the mounting slot on the lower frame 71, and then twist the first handle... The fourth screw 73 is rotated by the fourth handle, causing it to move downwards. This movement of the fourth screw 73 moves the upper frame 74 downwards, allowing it to fit onto the pipe and clamp it in place. This simple and quick operation improves pipe installation efficiency. Twisting the second handle rotates the second screw 32, causing it to move up and down. This movement of the second screw 32 moves the connecting seat 4 up and down, which in turn moves the rotating assembly 5 up and down. The rotating assembly 5 then moves the connecting mounting seat 6 up and down, which in turn moves the connecting fixing bracket 7 up and down. Twisting the third handle... When screw 54 rotates, the third screw 54 rotates and moves left and right. The third screw 54 drives the locking rack 55 to move left and right, causing the locking rack 55 to disengage from the locking gear 53, thereby releasing the lock on the connecting shaft 51. At this time, the connecting shaft 51 can rotate back and forth. The connecting shaft 51 drives the fixing block 52 to rotate, the fixing block 52 drives the mounting base 6 to rotate, and the mounting base 6 drives the connecting fixing bracket 7 to rotate, thereby adjusting the tilt angle of the connecting fixing bracket 7. After the angle is adjusted, the third handle is turned in the opposite direction, causing the locking rack 55 to move in the opposite direction and engage with the locking gear 53, thus fixing the connecting shaft 51.

[0030] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0031] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
