DETAILED DESCRIPTION

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0021] Reference Figure 1 - Figure 6As shown, the utility model provides a technical solution: a fiberglass chimney, comprising a chimney body 1, an arc-shaped adjusting block 2 is installed on the surface of the chimney body 1, an arc-shaped limiting block 3 is installed on one end of the arc-shaped adjusting block 2, the inner cavity of the arc-shaped adjusting block 2 is slidably connected to a connecting block 4, both sides of the connecting block 4 are fixedly connected to a fixing rod 5, the surface of the fixing rod 5 is slidably connected to a slide 6, a limiting groove 7 is provided inside the arc-shaped limiting block 3, the inner cavity of the limiting groove 7 is slidably connected to a fixing block 8, one end of the fixing block 8 close to the slide 6 is fixedly connected to the slide 6, one end of the connecting block 4 is fixedly connected to a connecting cylinder 9, an L-shaped notch 10 is provided on the surface of the arc-shaped limiting block 3, and the inner cavity of the L-shaped notch 10 is slidably connected to the There is a pull rod 11, and one end of the pull rod 11 close to the slide 6 is fixedly connected to the slide 6. When the staff needs to quickly splice the chimneys, the staff pulls the pull rod 11 vertically to make the surface of the pull rod 11 slide in the inner cavity of the L-shaped groove 10, and at the same time makes the pull rod 11 drive the slide 6 to move, so that the inner cavity of the slide 6 slides on the surface of the fixed rod 5. As the slide 6 moves, the slide 6 drives the surface of the fixed block 8 to gradually separate from the inner cavity of the limit groove 7. Then the staff pulls the pull rod 11 horizontally to drive the surfaces of the slide 6 and the fixed block 8 to gradually separate from the inner cavity of the arc-shaped limit block 3. Through the setting of the above structure, it is convenient to quickly splice the chimneys, thereby improving the splicing efficiency between the chimneys.

[0022] Reference Figure 3 As shown, in this embodiment: the inner cavity of the arc-shaped adjustment block 2 is fixedly connected with a first spring 12, and the end of the first spring 12 close to the connecting cylinder 9 is fixedly connected to the connecting cylinder 9. The staff pulls the pull rod 11 horizontally to drive the slide 6 and the fixed rod 5 to move. At the same time, the fixed rod 5 drives the connecting block 4 to move, so that the connecting block 4 drives the connecting cylinder 9 to move, and at the same time squeezes the first spring 12 to accumulate force. Through the setting of the first spring 12, the rebound force of the first spring 12 continues to push the connecting cylinder 9 and the connecting block 4 to reset, which facilitates the slide 6 and the fixed block 8 to move into the inner cavity of the arc-shaped limit block 3, further improving the coordination of the structure.

[0023] Reference Figure 3 As shown, in this embodiment, a slot 13 is formed within the arc-shaped adjustment block 2. A slider 14 is slidably connected to the inner cavity of the slot 13. The end of the slider 14, which is closest to the fixed rod 5, is fixedly connected to the fixed rod 5. When a worker pulls the pull rod 11, the fixed rod 5 is displaced. The fixed rod 5 drives the surface of the slider 14 to slide within the inner cavity of the slot 13. This arrangement ensures that the connecting block 4 maintains a directional displacement during displacement, preventing the connecting block 4 from deflecting and thus affecting the structural stability.

[0024] Reference Figure 3As shown, in this embodiment: both sides of the connecting block 4 are fixedly connected with a second spring 15, and the end of the second spring 15 close to the slide 6 is fixedly connected to the slide 6. The staff pulls the pull rod 11 vertically to drive the slide 6 to move, and at the same time squeezes the second spring 15 to store force. Through the setting of the second spring 15, the rebound force of the second spring 15 continues to push the slide 6 to reset, and at the same time, the slide 6 drives the surface of the fixed block 8 to insert into the inner cavity of the limit groove 7, completing the docking of the arc adjustment block 2 and the arc limit block 3.

[0025] Reference Figure 6 As shown, in this embodiment: the inner cavity of the chimney body 1 is fixedly connected with a first protective layer 16, and the shape of the first protective layer 16 is tubular. Through the setting of the first protective layer 16, the surface of the first protective layer 16 is more closely attached to the inner wall of the chimney body 1. At the same time, the material of the first protective layer 16 is glass fiber, which further improves the strength and rigidity of the glass fiber reinforced plastic.

[0026] Reference Figure 6 As shown, in this embodiment: the interior of the first protective layer 16 is fixedly connected to the second protective layer 17, and the shape of the second protective layer 17 is tubular. Through the setting of the second protective layer 17, the surface of the second protective layer 17 is more closely attached to the inner wall of the first protective layer 16. At the same time, the material of the second protective layer 17 is lining resin, which has good corrosion resistance and can resist acidic substances in the flue gas.

[0027] Working principle: When the staff needs to quickly splice the chimneys, the staff pulls the pull rod 11 vertically to make the surface of the pull rod 11 slide in the inner cavity of the L-shaped groove 10, and at the same time makes the pull rod 11 drive the slide 6 to move, so that the inner cavity of the slide 6 slides on the surface of the fixed rod 5. As the slide 6 moves, the slide 6 drives the surface of the fixed block 8 to gradually separate from the inner cavity of the limit groove 7. Then the staff pulls the pull rod 11 horizontally to drive the surfaces of the slide 6 and the fixed block 8 to gradually separate from the inner cavity of the arc-shaped limit block 3. Through the setting of the above structure, it is convenient to quickly splice the chimneys, thereby improving the splicing efficiency between the chimneys.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
