Description

Technical Field

[0001] This utility model relates to the field of chimney damper technology, and in particular to an adjustable-angle chimney damper. Background Technology

[0002] Boilers are installed in many factories. In order for the flue gas produced by the boiler to be discharged from the factory, a chimney is connected to the flue pipe of the boiler. In order to reduce the swaying and vibration of the chimney caused by external factors such as wind and pressure changes, a chimney damper is installed at the outer end of the chimney to ensure the stability of the chimney.

[0003] However, existing chimney dampers are generally fixed support iron frames that cannot be adjusted and are difficult to apply to chimneys of different radii. Moreover, sometimes in order to reduce the impact of flue gas on the surrounding environment or residential areas, chimneys are tilted to adjust the direction of flue gas emission. Existing chimney dampers cannot adjust the angle, making them difficult to use, and they have poor flexibility and limited applicability.

[0004] To solve this technical problem, this utility model proposes an adjustable-angle chimney damper. Utility Model Content

[0005] The main objective of this invention is to provide an adjustable-angle chimney damper that can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An adjustable-angle chimney damper includes a rotating semicircular frame, a clamping plate disposed inside the rotating semicircular frame, a rotating shaft connected to the outer end of the rotating semicircular frame, a fixed rod connected inside the rotating shaft, a groove formed on the outer surface of the fixed rod, a fixed tube rotatably connected to the outer end of the rotating shaft, a fixed bolt rod threadedly connected inside the fixed tube, a fixed semicircular plate rotatably connected to the side end of the fixed bolt rod, a protruding strip connected to the inner surface of the fixed semicircular plate, a first rotating head connected to the side end of the fixed bolt rod, and a support frame connected to the lower end of the fixed tube.

[0008] Preferably, a connecting groove is provided on one side of the rotating semicircular frame, and a connecting block is connected to the other side. The size of the connecting block is such that it can be inserted into the connecting groove. A connecting plate is connected to the outer end of the rotating semicircular frame, and a connecting hole is provided in the connecting plate, into which a bolt is connected.

[0009] Preferably, the outer surface of the clamping plate is provided with an anti-slip groove, the outer end of the rotating semi-circular frame is connected to a sleeve, the sleeve is provided with a square groove, and a movable square tube is slidably connected inside the sleeve.

[0010] Preferably, the side end of the movable square tube is connected to the clamping plate, the movable square tube is slidably connected within the rotating semicircular frame, the movable square tube has a threaded groove, and an adjusting threaded rod is threadedly connected within the movable square tube.

[0011] Preferably, the side end of the adjusting threaded rod is rotatably connected inside the sleeve, and the side end of the sleeve is provided with a second rotating head. The second rotating head is connected to the adjusting threaded rod, and anti-slip grooves are provided at the outer ends of both the second rotating head and the first rotating head.

[0012] Preferably, the fixing rod is located inside the fixing tube, the fixing semicircular plate slides between the fixing rod and the fixing tube, and the protrusion can be engaged in the groove.

[0013] Preferably, mounting plates are connected to both sides of the support frame, and mounting holes are provided in the mounting plates.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In this invention, a rotating shaft and a fixed tube are provided. The rotating shaft can rotate within the fixed tube, thereby causing the rotating semicircular frame to rotate. This allows adjustment of the clamping direction of the clamping plate, making the device suitable for chimneys at different angles. It offers good flexibility and strong applicability. A fixed semicircular plate and a fixed bolt are also provided. Once the clamping plate is in place to hold the chimney, rotating the first rotating head will cause the fixed bolt to rotate. The rotation of the fixed bolt will push the fixed semicircular plate to move, allowing the protrusion on the inner side of the fixed semicircular plate to engage with the groove at the outer end of the fixed rod. This clamps and fixes the rotating shaft, thereby securing the rotating semicircular frame and the clamping plate, and ultimately fixing the chimney. The operation is simple and effectively improves the stability of the chimney.

[0016] In this invention, a clamping plate is provided, which can clamp the outer end of the chimney. A movable square tube and an adjusting threaded rod are provided. Rotating the second rotating head will drive the adjusting threaded rod to rotate. The rotation of the adjusting threaded rod and the movable square tube act together. Under the constraint of the sleeve, the movable square tube cannot rotate, thereby pushing the clamping plate to move. This allows the chimney to be clamped and fixed, and chimneys of different radii can be clamped and fixed. This device has a simple structure, is easy to operate, and can clamp and fix chimneys of different radii. It has good flexibility and strong applicability. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1-5 As shown, an adjustable-angle chimney damper includes a rotating semicircular frame 1. A connecting groove 12 is provided on one side of the rotating semicircular frame 1, and a connecting block 13 is connected to the other side. The size of the connecting block 13 is such that it can be inserted into the connecting groove 12, thereby enabling two rotating semicircular frames 1 to be joined together. A connecting plate 14 is connected to the outer end of the rotating semicircular frame 1. A connecting hole is provided in the connecting plate 14, and a bolt is connected in the connecting hole. By passing the bolt through the two connecting plates 14, the two rotating semicircular frames 1 can be connected and fixed together.

[0025] A clamping plate 2 is installed inside the rotating semicircular frame 1. The outer surface of the clamping plate 2 has an anti-slip groove to increase friction between the clamping plate 2 and the chimney, thereby improving the clamping and fixing effect of the clamping plate 2. A sleeve 15 is connected to the outer end of the rotating semicircular frame 1. A square groove is provided inside the sleeve 15, and a movable square tube 16 is slidably connected inside the sleeve 15. The movable square tube 16 cannot rotate under the constraint of the sleeve 15. The side end of the movable square tube 16 is connected to the clamping plate 2, and the movable square tube 16 is slidably connected... The movable square tube 16, which is connected to the rotating semi-circular frame 1, has a threaded groove. An adjusting threaded rod 17 is threadedly connected to the movable square tube 16. The side end of the adjusting threaded rod 17 is rotatably connected to the sleeve 15. A second rotating head 18 is provided on the side end of the sleeve 15. The second rotating head 18 is connected to the adjusting threaded rod 17. The second rotating head 18 can drive the adjusting threaded rod 17 to rotate, thereby driving the movable square tube 16 to move, which in turn pushes the clamping plate 2 to move, thereby clamping and fixing the chimney.

[0026] A rotating shaft rod 3 is connected to the outer end of the rotating semicircular frame 1. A fixing rod 4 is connected inside the rotating shaft rod 3. A groove 5 is opened on the outer surface of the fixing rod 4. A fixing tube 6 is rotatably connected to the outer end of the rotating shaft rod 3. The rotating shaft rod 3 can drive the rotating semicircular frame 1 to rotate, thereby adjusting the direction of the clamping plate 2 so that it can be applied to chimneys with different inclination angles. The fixing rod 4 is located inside the fixing tube 6. A fixing bolt rod 7 is threaded inside the fixing tube 6. A fixing semicircular plate 8 is rotatably connected to the side end of the fixing bolt rod 7. The fixing semicircular plate 8 slides between the fixing rod 4 and the fixing tube 6, so that the fixing semicircular plate 8 cannot rotate. A protrusion 9 is connected to the inner surface of the fixing semicircular plate 8. The protrusion 9 can be locked in the groove 5, thereby clamping and fixing the fixing rod 4, thereby fixing the angle of the rotating shaft rod 3, the rotating semicircular frame 1, and the clamping plate 2.

[0027] The first rotating head 10 is connected to the side end of the fixing bolt rod 7. The second rotating head 18 and the outer end of the first rotating head 10 are both provided with anti-slip grooves. The anti-slip grooves are used to facilitate manual rotation of the first rotating head 10 and the second rotating head 18. The lower end of the fixing tube 6 is connected to the support frame 11. The support frame 11 is connected to the two sides of the support frame 11 with mounting plates 19. The mounting plates 19 are provided with mounting holes. The support frame 11 can be connected and fixed to the wall or the ceiling through the mounting plates 19.

[0028] When using this device: Position the two rotating semicircular frames 1 at the outer end of the chimney, then insert the connecting blocks 13 at the sides of the two rotating semicircular frames 1 into each other's connecting slots 12, thus aligning the two rotating semicircular frames 1. Then, use bolts to pass through the connecting plates 14 of both, thus connecting and fixing the two rotating semicircular frames 1 together. Then, fix the support frame 11 to the wall or roof using the mounting plate 19. Since the rotating shaft 3 can rotate within the fixed tube 6, the angle of the rotating semicircular frames 1 and the clamping plate 2 can be adjusted so that the clamping plate 2 is parallel to the chimney. Rotate the second rotating head 18 to drive the adjustment... The threaded rod 17 rotates, and the rotation of the threaded rod 17 interacts with the moving square tube 16. The moving square tube 16 cannot rotate under the constraint of the sleeve 15, thus pushing the clamping plate 2 to move, thereby clamping and fixing the chimney. After the clamping plate 2 is fixed, the first rotating head 10 is rotated, which will drive the fixing bolt rod 7 to rotate, thereby pushing the fixing semicircular plate 8 to move, so that the inner protrusion 9 connects with the groove 5 at the outer end of the fixing rod 4, thereby fixing the fixing rod 4, thereby fixing the rotating shaft rod 3, and fixing the angle of the rotating semicircular frame 1 and the clamping plate 2.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
