Detailed Implementation

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] Please refer to the appendix. Figures 1-4 The present invention provides a multifunctional smoke exhaust duct connection structure, including a first smoke exhaust duct 1 and a second smoke exhaust duct 2. A connection mechanism is detachably installed between the first smoke exhaust duct 1 and the second smoke exhaust duct 2. The connection mechanism includes a connection component, which is detachably installed between the first smoke exhaust duct 1 and the second smoke exhaust duct 2. A hoisting component is installed on the top of the connection component through a shock-absorbing component.

[0023] The connecting assembly includes a connecting pipe 3. Both ends of the connecting pipe 3 are fixedly installed at the opposite ends of the first smoke exhaust duct 1 and the second smoke exhaust duct 2 by the first fixing bolt 4. Rubber sealing gaskets 5 are also fixed at the opposite ends of the first smoke exhaust duct 1 and the second smoke exhaust duct 2. The rubber sealing gaskets 5 abut against the ends of the connecting pipe 3. Specifically, under the connection action of the first fixing bolt 4, the connecting pipe 3 can be detachably and fixedly installed between the first smoke exhaust duct 1 and the second smoke exhaust duct 2. The operator only needs to remove and install the first fixing bolt 4 to control the disassembly and assembly of the connecting pipe 3 with the first smoke exhaust duct 1 and the second smoke exhaust duct 2. The operation is convenient. Moreover, under the sealing action of the rubber sealing gasket 5, the sealing performance of the connection between the connecting pipe 3 and the first smoke exhaust duct 1 and the second smoke exhaust duct 2 can be effectively guaranteed.

[0024] The hoisting assembly includes a fixed plate 6, with mounting screws 7 threaded at the corners of the fixed plate 6 to fix the fixed plate 6 in the required position. An adjusting pipe 8 is vertically fixed at the bottom center of the fixed plate 6. Several adjusting holes 9 are symmetrically opened on both sides of the adjusting pipe 8, arranged from top to bottom. An adjusting plate 10 is vertically inserted inside the adjusting pipe 8. A connecting hole 11 is opened at the top of the adjusting plate 10. The connecting hole 11 and the adjusting hole 9 are fixedly connected by a second fixing bolt 12. Specifically, under the fixing action of the second fixing bolt 12, the adjusting plate 10 and the adjusting pipe 8 can be fixedly connected. Moreover, the operator can pull the adjusting plate 10 up and down, and then pass the second fixing bolt 12 through the connecting hole 11 and the adjusting holes 9 at different positions to achieve the function of fixing the adjusting plate 10 at different heights. That is, this smoke exhaust duct connection structure can not only connect the smoke exhaust duct, but also realize the function of hoisting the smoke exhaust duct at different heights.

[0025] The shock absorption assembly includes a vertically arranged connecting guide rod 13, the top of which is fixed to the bottom of the adjusting plate 10. A housing 14 is fixed to the top of the connecting pipe 3. A limit hole 15 is vertically opened at the center of the top of the housing 14. The connecting guide rod 13 vertically passes through the limit hole 15, and the surface of the connecting guide rod 13 is in contact with the wall of the limit hole 15. A limit plate 16 is fixed to the bottom of the connecting guide rod 13. A buffer spring 17 is vertically fixed to the top of the limit plate 16. The top of the buffer spring 17 is fixed to the top of the inner wall of the housing 14. Several damping springs are vertically fixed to the bottom of the inner wall of the housing 14. Dampers 18, the movable ends of several dampers 18 are all fixed to the bottom of the limiting plate 16. Specifically, when the first exhaust duct 1, the connecting pipe 3 and the second exhaust duct 2 vibrate due to gas flow, the box 14 can be driven to shake up and down, thereby causing the buffer spring 17 to undergo elastic deformation and generate buffering force, thus buffering the vibration force. Under the damping action of the dampers 18, the vibrating exhaust duct can quickly stabilize. That is, the exhaust duct connection structure can also effectively buffer the vibrating exhaust duct, which is beneficial to the stability of the exhaust duct.

[0026] The usage process of this utility model is as follows: First, the operator only needs to remove and install the first fixing bolt 4 to control the disassembly and assembly of the connecting pipe 3 with the first smoke exhaust duct 1 and the second smoke exhaust duct 2. The operation is convenient, and the sealing performance of the connection between the connecting pipe 3 and the first smoke exhaust duct 1 and the second smoke exhaust duct 2 can be effectively guaranteed by the sealing effect of the rubber sealing gasket 5. Second, the operator can pull the adjusting plate 10 up and down, and then use the second fixing bolt 12 to pass through the connecting hole 11 and the adjusting holes 9 at different positions to achieve the function of fixing the adjusting plate 10 at different heights. The smoke exhaust duct connection structure not only connects the smoke exhaust ducts but also allows for the installation of smoke exhaust ducts at different heights. Finally, when the first smoke exhaust duct 1, connecting pipe 3, and second smoke exhaust duct 2 vibrate due to gas flow, the housing 14 can be moved up and down, causing the buffer spring 17 to undergo elastic deformation and generate buffering force, thereby buffering the vibration force. Under the damping action of the damper 18, the vibrating smoke exhaust duct can quickly stabilize. In other words, the smoke exhaust duct connection structure can effectively buffer the vibrating smoke exhaust duct, which is beneficial to the stability of the smoke exhaust duct in use.
