[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0032] Reference Figures 1 to 3The utility model provides an embodiment of a smoke exhaust duct guide device, comprising a guide pipe 1 and a connecting pipe 2. The rear end of the guide pipe 1 contacts the front end of the connecting pipe 2. The corners of the guide pipe 1 are rounded to perform a rounded corner treatment so that it can guide the discharged smoke. The inner wall of the guide pipe 1 is rotatably connected to a rotating shaft 3. The guide pipe 1 here provides a stable support for the rotating shaft 3. The outside of the rotating shaft 3 is fixedly connected to a side plate 1 4. The outside of the side plate 1 4 is slidably connected to the inner wall of the guide pipe 1. The outside of the rotating shaft 3 can drive the side plate 1 4 here to rotate when the rotating shaft 3 rotates. The outside of the rotating shaft 3 is rotatably connected to the inner wall of the top end of the guide pipe 1. The outside of the multiple collars 5 is fixedly connected to the side plate 2 6. The collar 5 here can drive the side plate 2 6 here to rotate when it rotates. The outside of the side plate 2 6 is slidably connected to the inner wall of the guide pipe 1. The outer top of the rotating shaft 3 and the outer top of one of the collars 5 are fixedly connected to a sliding column 7.
[0033] The outer sides of the two slide posts 7 are slidably connected with a slide box 8. When the slide box 8 here slides, it can drive the slide post 7 here to slide and change its angle at the same time. The bottom end of the slide box 8 is slidably connected to the top of the guide tube 1. The outer side of one of the collars 5 is rotatably connected to the inner wall of the slide box 8. The rear end of the slide box 8 is fixedly connected with a rubber plate 9. The rubber plate 9 here has a certain elasticity, and the stable state is shown in the figure. The bottom end of the rubber plate 9 is fixedly connected with a card block 10. The outer side of the card block 10 is in a card-engaging relationship with the inner wall of the top end of the guide tube 1. When the smoke exhaust rate needs to be adjusted, the rubber plate 9 can be pulled upward to make the card block 10 disengage from the inner wall of the top end of the guide tube 1, and then the rubber plate 9 is pulled backward to drive the slide box 8 to slide, thereby driving the slide post 7, the collar 5 and the rotating shaft 3 to rotate, and further driving the rotation of the side plate 1 4 and the side plate 2 6.
[0034] The rear end of the inner wall of the guide tube 1 is fixedly connected with a sealing component for providing sealing. The sealing component includes a retaining ring 11. The outer portion of the retaining ring 11 is fixedly connected to the rear end inner wall of the guide tube 1. The guide tube 1 here provides a stable support for the retaining ring 11. The front end inner wall of the connecting tube 2 is fixedly connected with an inner box 12. The inner wall of the inner box 12 is slidably connected with an extrusion ring 13. The front end of the extrusion ring 13 contacts the rear end of the retaining ring 11. The rear end of the extrusion ring 13 is fixedly connected with a limiting ring 14. The limiting ring 14 here can effectively prevent the extrusion ring 13 from accidentally detaching from the interior of the inner box 12. The outer sliding connection of the limiting ring 14 On the inner wall of the inner box 12, the rear end of the limiting ring 14 is fixedly connected with a spring 15, and the spring 15 here is in an extruded state. The other end of the spring 15 is fixedly connected to one side of the inner wall of the inner box 12, and the rear end of the guide pipe 1 is slidably connected to the outside with a fixed ring 16. When the guide pipe 1 and the connecting pipe 2 are in contact, the extrusion ring 13 here will be squeezed by the fixed retaining ring 11, thereby squeezing the spring 15 inside the inner box 12 to cause it to shrink, and at the same time giving the extrusion ring 13 a reaction force to squeeze it more tightly with the retaining ring 11, thereby improving the sealing between the guide pipe 1 and the connecting pipe 2 and preventing smoke leakage.
[0035] The inner wall of the fixing ring 16 is slidably connected to the outside of the connecting pipe 2, and the upper and lower inner walls of the fixing ring 16 are fixedly connected to the limiting blocks 17. The fixing ring 16 here provides a stable support for the limiting blocks 17, and the outer part of the limiting blocks 17 is slidably connected to the inner wall of the guide pipe 1. The rear end of the limiting block 17 is fixedly connected with a clip 18. The limiting block 17 here can effectively prevent the clip 18 from accidentally detaching from the inner wall of the fixing ring 16. At the same time, the material of the clip 18 here is plastic, which has strong elasticity and toughness. The outer part of the clip 18 is in a snap-fitting relationship with the front inner wall of the connecting pipe 2.
[0036] When the connecting pipe 2 and the guide pipe 1 need to be installed, the two can be aligned first, and then the fixing ring 16 can be slid to move it toward the front end of the connecting pipe 2. When it moves to the rear end of the connecting pipe 2, the card strip 18 will contact the connecting pipe 2. Because the front end of the card strip 18 is hook-shaped and has a small slope, and the groove opened at the rear end of the connecting pipe 2 is also larger, the card strip 18 will slide into the inside of the groove, and then the fixing ring 16 continues to move toward the front end of the connecting pipe 2 until the card strip 18 moves to the position of the card groove. At this time, the card strip 18 will quickly reset, thereby completing the installation with the guide pipe 1 and the connecting pipe 2. This installation method is more tight and stable under the extrusion of the extrusion ring 13 and the retaining ring 11.
[0037] Working principle: First, when the smoke exhaust rate needs to be adjusted, the rubber plate 9 can be pulled upward (the rubber plate 9 here has strong elasticity and can be quickly reset after bending to a certain extent) to make the block 10 separate from the top inner wall of the guide tube 1, and then the rubber plate 9 is pulled backward to drive the slide box 8 to slide, thereby driving the slide column 7, the ring 5 and the rotating shaft 3 to rotate, and further driving the rotation of the side plate 1 4 and the side plate 2 6.
[0038] At the same time, when the guide pipe 1 and the connecting pipe 2 are in contact, the extrusion ring 13 here will be squeezed by the fixed retaining ring 11, thereby squeezing the spring 15 inside the inner box 12, causing it to shrink, and at the same time giving the extrusion ring 13 a reaction force, so that it is squeezed more tightly with the retaining ring 11, thereby improving the sealing between the guide pipe 1 and the connecting pipe 2 and preventing smoke leakage.
[0039] Secondly, when the connecting pipe 2 and the guide pipe 1 need to be installed, the two can be aligned first, and then the fixing ring 16 can be slid to move it toward the front end of the connecting pipe 2. When it moves to the rear end of the connecting pipe 2, the card strip 18 (the card strip 18 is made of rubber, has strong elasticity and toughness, and can be quickly reset after bending) will contact the connecting pipe 2. Because the front end of the card strip 18 is hook-shaped, it has a small landslide, and the groove opened at the rear end of the connecting pipe 2 is also large. At this time, the card strip 18 will slide into the inside of the groove, and then the fixing ring 16 continues to move toward the front end of the connecting pipe 2 until the card strip 18 moves to the position of the card groove. At this time, the card strip 18 will quickly reset, thereby completing the installation with the guide pipe 1 and the connecting pipe 2. This installation method is more tight and stable under the extrusion of the extrusion ring 13 and the retaining ring 11.
[0040] 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. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
