[0026] In order to make the purpose, technical solutions and advantages of the present invention more clear and distinct, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Example 1

[0027] See also Figures 1 to 3The utility model provides a supporting flue fixing bracket, including a flue body 1 and an air inlet pipe 2 connected to the bottom of the flue body 1. The flue body 1 has a built-in fixing component, the bottom surface of the fixing component is connected to a fixing shaft 3, the bottom end of the fixing shaft 3 is provided with a limit block 4, and the outer circumference of the fixing shaft 3 is also provided with a sliding ring 5. The top surface of the sliding ring 5 is connected to the bottom surface of the fixing component through a tension spring 6. The sliding ring 5 abuts against the bottom surface of the air inlet pipe 2 through a movable frame. A pull rope 7 is connected to the bottom of the sliding ring 5, and the pull rope 7 passes through the limit block 4. An elastic component is provided in the fixed shaft 3, and the elastic component is used to fix the sliding ring 5.

[0028] Specifically, the flue body 1 of the present invention has a built-in fixing assembly, and a fixing shaft 3 is connected to the bottom of the fixing assembly. A sliding ring 5 is provided on the outer circumference of the fixing shaft 3 to move up and down on the fixing shaft 3, and cooperates with the elastic assembly to be stably connected below the elastic assembly. When the pull rope 7 pulls down the sliding ring 5 to make it slide down, the sliding ring 5 pulls the tension spring 6 downward, thereby driving the movable frame to open and abut against the bottom of the air outlet pipe, so that the movable frame stably supports the air inlet pipe 2, thereby reinforcing the air inlet pipe 2 at the bottom of the flue body 1, preventing the air inlet pipe 2 from easily falling off and distorting, and failing to perform normal exhaust work, thereby extending the service life. The limit block 4 is used to abut the bottom end of the fixed shaft 3 to limit the pull rope 7 inside it. The pull rope 7 is scattered, affecting the appearance. At the same time, it can also prevent the bottom of the fixed shaft 3 from accidentally stabbing the staff.

[0029] Among them, the limit block 4 is threadedly connected to the bottom of the fixed shaft 3, which makes it easy to disassemble and replace the movable frame, thereby extending the service life of the movable frame and providing a better support foundation for the air inlet pipe 2.

[0030] Preferably, a rubber pad 8 is provided on the bottom surface of the air inlet pipe 2 to abut against the end of the movable frame. By abutting the rubber pad 8 against the end of the movable frame, the friction force possessed by the rubber pad 8 is utilized to stably contact the end of the movable frame, thereby improving the support stability of the movable bracket.

[0031] In the above embodiment, the movable frame includes a first connecting rod 9 and a second connecting rod 10. One end of the first connecting rod 9 is hinged to the outer peripheral surface of the fixed shaft 3, and the other end is abutted against the rubber pad 8. The outer peripheral surface of the first connecting rod 9 is hinged to the second connecting rod 10, and the other end of the second connecting rod 10 is hinged to the outer peripheral surface of the sliding ring 5.

[0032] The first connecting rod 9 and the second connecting rod 10 are steel bars with good stability to support the air inlet pipe 2. When the sliding ring 5 slides along the bottom end of the fixed shaft 3, it pushes the second connecting rod 10, which pushes the first connecting rod 9 to expand, so that the end of the first connecting rod 9 contacts the rubber pad 8, thereby supporting the air inlet pipe 2 and stably connecting it to the flue.

[0033] Preferably, the fixed shaft 3 is a hollow tube with an elastic component built in. The elastic component is conveniently arranged in the hollow tube.

[0034] In the above embodiment, the elastic component includes an elastic plate 11 and a card body 12. One end of the elastic plate 11 is fixed to the inner wall of the fixed shaft 3, and the other end is provided with a card body 12. The card body 12 penetrates the side wall of the fixed shaft 3 and moves inside and outside the fixed shaft 3.

[0035] For example, when the sliding ring 5 slides down, the card body 12 is in the shape of a quarter circle, so that the sliding rod slides through the card body 12, and the card body 12 is pressed into the fixed shaft 3. At this time, the elastic plate 11 is in a curved shape. When the sliding ring 5 completely passes through the card body 12, the card body 12 is ejected from the inside of the fixed shaft 3 by the elastic plate 11, and then the card body 12 can clamp the sliding ring 5 on the bottom surface of the card body 12. Through the tension of the tension spring 6 and the limitation of the card body 12, the sliding ring 5 can stably unfold the first connecting rod 9 and the second connecting rod 10, thereby stably supporting the air inlet.

[0036] Preferably, the fixing assembly includes a telescopic rod, a first bonding plate 19 and a second bonding plate 20. The first bonding plate 19 and the second bonding plate 20 are symmetrically attached to the inner wall of the flue body 1. The first bonding plate 19 and the second bonding plate 20 are provided with a first card slot 21 and a second card slot 22. One end of the telescopic rod extends into the first card slot 21, and the other end is connected to the second card slot 22.

[0037] For example, by extending one end of the telescopic rod into the first slot 21 and the other end into the second slot 22, the telescopic rod can stabilize the fixed shaft 3 in the flue body 1, allowing the sliding ring 5 to perform normal work. In addition, the telescopic rod can be used to disassemble and regularly inspect the fixed shaft 3, improving safety and service life.

[0038] Furthermore, the telescopic rod includes a strip plate 23 , a round rod 24 slides inside the strip plate 23 , one end of the strip plate 23 is engaged with the first slot 21 , and the round rod 24 slides into the second slot 22 and is threadedly connected to the second slot 22 .

[0039] One end of the strip plate 23 is engaged with the first slot 21, and the round rod 24 is extended toward the second slot 22. By rotating the round rod 24, one end of the round rod 24 is connected to the thread on the inner wall of the second slot 22, thereby achieving a fixing effect.

[0040] In addition, the round rod 24 is rotated in the reverse direction according to the above principle, so that the round rod 24 is disengaged from the second slot 22 , and then the strip plate 23 is disengaged from the first slot 21 , thereby completing the disassembly work. Example 2

[0041] See also Figure 4 A magnified image and Figure 5In another possible implementation of the present invention, compared with the first embodiment, the difference is that the elastic component includes a fixed plate 13, a rotating block 14, a telescopic curved rod and a clamping plate 15, both ends of the fixed plate 13 are fixedly connected to the inner wall of the fixed shaft 3 through a cross bar, a rotating block 14 and a telescopic curved rod are provided on one side of the fixed plate 13, the clamping plate 15 passes through the side wall of the fixed shaft 3 and is rotatably connected to the rotating block 14, and the other side is connected to the telescopic curved rod.

[0042] It should be noted that Figure 4 Except for the enlarged view of point A, the rest of the numbers are the same as Figure 3 In order to save time and improve aesthetics, no marking is done.

[0043] For example, the card plate 15 is shaped like the card body 12. When the sliding ring 5 passes through the card plate 15, it is pressed into the fixed shaft 3. At this time, one end of the card plate 15 rotates within the rotating block, while the other end presses down on the telescopic crank rod. The telescopic crank rod adapts the card plate 15 to make a circular motion into the fixed shaft 3, thereby completely sinking the card plate 15 into the fixed shaft 3. When the sliding ring 5 completely passes through the card plate 15, the telescopic crank rod ejects the card plate 15 out of the fixed shaft 3, and the card plate 15 can then be clamped to the bottom surface of the card plate 15, preventing the tension spring 6 from pulling the sliding ring 5 upward and affecting the stable support of the movable frame.

[0044] Furthermore, the telescopic curved rod includes a curved hollow column 16 and a curved roller 17. The bottom end of the curved hollow column 16 is fixed to the side of the fixed plate 13. A spring 18 is provided along the length of the inner wall of the inner bottom. The curved rod extends into the curved hollow column 16 and is fixed to the other end of the spring 18.

[0045] Specifically, when the card plate 15 is pressed down, with the rotating block 14 as the base point, the movement path when the other end is pressed down is an arc, and the adaptive curved roller 17 presses the spring 18 into the curved hollow column 16. When the sliding ring 5 completely passes through the card plate 15, the curved roller 17 is popped out by the spring 18 to pop the card plate 15 out of the fixed shaft 3.

[0046] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
