[0026] Reference Figure 1-Figure 4 , a new type of buckle lifting smoke exhaust pipe, including a first smoke exhaust pipe 1, a connecting seat 3 is fixed to the top of the first smoke exhaust pipe 1 by screws, a circular fire damper 4 is fixed to the top of the connecting seat 3, so that the circular fire damper 4 can effectively stop the fire and prevent the fire from spreading when a fire occurs. The model of the circular fire damper 4 is FYHF-SFVD, so that the smoke exhaust pipe can be safer when in use, a fixed base 2 is fixed to the bottom of the first smoke exhaust pipe 1 by screws, a second smoke exhaust pipe 5 is slidably connected to the inside of the first smoke exhaust pipe 1, and the second smoke exhaust pipe 5 is slidably connected to the fixed base 2, so that the second smoke exhaust pipe 5 can be adjusted inside the first smoke exhaust pipe 1 and lifted inside the fixed base 2, so that the suction force inside the first smoke exhaust pipe 1 can be directly given to the second smoke exhaust pipe 5 through the fit between the fixed base 2 and the second smoke exhaust pipe 5, and a suction hood 6 is fixed to the bottom of the second smoke exhaust pipe 5 by screws, so that the smoke on the top of the barbecue stove is absorbed and discharged to the outside through the suction hood 6;

[0027] A lifting mechanism for height adjustment is installed inside the second smoke exhaust pipe 5, and the lifting mechanism includes an adjusting column 7, a fixing platform 8, a connecting platform 9, a fixing frame 11, a limit block 12, a positioning bolt 13 and a torsion spring 14. A fixing platform 8 is fixed to the top of the adjusting column 7, and the fixing platform 8 is fixed to the first smoke exhaust pipe 1, so that the fixing platform 8 can be fixed inside the top of the first smoke exhaust pipe 1, and the fixing platform 8 is located at the bottom of the connecting seat 3. The outer side of the adjusting column 7 is slidably connected with a fixing frame 11, and the outer side of the fixing frame 11 is fixed with a connecting platform 9, and the connecting platform 9 is fixed to the second smoke exhaust pipe 5, so that the lifting and rotation of the second smoke exhaust pipe 5 drives the connecting platform 9 to be lifted and rotated, and the connecting platform 9 drives the fixing frame 11 to be lifted and rotated on the outer side of the adjusting column 7;

[0028] A limit block 12 is fixed to one side of the fixing frame 11, and the limit block 12 is fixed to the connecting platform 9, so that the rotation of the connecting platform 9 drives the fixing frame 11 and the limit block 12 to rotate simultaneously, and the internal thread of the limit block 12 is connected with a positioning bolt 13, and the outer side of the positioning bolt 13 and the bottom of the limit block 12 are sleeved with a torsion spring 14, so that the height position of the torsion spring 14 can be limited by the cooperation of the nut on the positioning bolt 13 and the limit block 12, and the plane position of the torsion spring 14 can be limited by the threaded outer side of the positioning bolt 13, and one end of the torsion spring 14 is slidably connected with the adjusting column 7, so that one end of the torsion spring 14 can enter the interior of the adjusting column 7, and the interior of one end of the adjusting column 7 is evenly provided with positioning grooves 10, one end of the torsion spring 14 is slidably connected with the positioning groove 10, and the other end of the torsion spring 14 contacts with the connecting platform 9, so that the rotation of the connecting platform 9 drives one end of the torsion spring 14 to disengage from the interior of the positioning groove 10 on the adjusting column 7, so that the connecting platform 9 can be raised and lowered on the outer side of the adjusting column 7.

[0029] In this embodiment, the diameter of the torsion spring 14 is only for reference. In other embodiments, the diameter of the torsion spring 14 can be replaced according to the specific weight of the second smoke exhaust pipe 5, the air suction hood 6, the connecting platform 9, etc., and the size of the positioning groove 10 can be adjusted according to the diameter of the torsion spring 14.

[0030] The use process of a novel buckle lifting smoke exhaust pipe provided by the utility model is as follows: after the position of the first smoke exhaust pipe 1 is installed and fixed, the height of the second smoke exhaust pipe 5 is adjusted according to the height of the barbecue grill, and then the distance between the air suction hood 6 and the barbecue grill is adjusted, first the second smoke exhaust pipe 5 is rotated so that the second smoke exhaust pipe 5 drives the connecting platform 9 to rotate, and the rotation of the connecting platform 9 drives the fixing frame 11 and the limit block 12 to rotate at the same time, so that the rotation of the limit block 12 drives the positioning bolt 13 to rotate, and the rotation of the positioning bolt 13 drives the torsion spring 14 to rotate at the same time, so that one end of the torsion spring 14 located inside the positioning groove 10 is disengaged from the positioning groove 10 by rotation, so that one end of the torsion spring 14 contacts the smooth surface on the adjusting column 7, and the torsion spring 14 is compressed by the contact between the other end of the torsion spring 14 and the connecting platform 9, at this time, the second smoke exhaust pipe 5 is pulled, so that the second smoke exhaust pipe 5 is lifted and lowered to drive the connecting platform 9 to lift and lower, so that the connecting platform 9 and the fixing frame 11 are lifted and lowered on the outside of the adjusting column 7 to adjust the height;

[0031] When the height of the second smoke exhaust pipe 5 is raised or lowered, the second smoke exhaust pipe 5 is rotated in the opposite direction, so that the second smoke exhaust pipe 5 drives the connecting platform 9 to rotate in the opposite direction, and the connecting platform 9 drives the fixing frame 11 and the limit block 12 to rotate in the opposite direction at the same time, and the rotation of the limit block 12 drives the torsion spring 14 to rotate in the opposite direction through the positioning bolt 13. At this time, the compression of the torsion spring 14 rebounds, so that one end of the torsion spring 14 enters the interior of the positioning groove 10, and the height of the second smoke exhaust pipe 5 is fixed by the rigidity and hardness of the positioning groove 10 itself.
