Abstract

The invention discloses an air volume adjustment switch, which comprises a bracket, a push-pull track, an air volume adjustment piece, a rotating shaft, a movable connecting rod and a knob. The push-pull track is arranged on the bracket, and a slide block is arranged inside the push-pull track. , a connecting rod seat is fixed on the slider, and the connecting rod seat is movably connected with one end of the movable connecting rod, and the other end of the movable connecting rod is connected with the air volume regulating piece, and the said knob is threadedly connected with the slider; There are two shaft sleeves, each of which is connected to a rotating shaft, and the other ends of the two rotating shafts are respectively connected to the two ends of the spring, and the spring is fixed in the middle of the air volume adjustment plate through the clamping case , the two rotating shafts are fixed on the surface of the air volume regulating piece. The invention is inlaid on the pipe wall of the range hood, which is easy to replace and repair. At the same time, a longitudinal push-pull track and a movable connecting rod are arranged to make it stretch freely. .

Description

technical field [0001] The invention relates to an air volume regulating switch, in particular to an air volume regulating switch used in barbecue range hoods in the catering industry. Background technique [0002] There are two types of barbecue range hoods for traditional catering: one is square and the other is round. When designing the air volume adjustment switch for square ducts, two parallel slots are mainly added to the inner side of the square duct wall, and the slots are opened horizontally on the square duct wall, and the slots are inserted into the slots by hand to adjust the air volume. Its disadvantages are: the plugboard is only suitable for square shape, and the push and pull of the plugboard is not smooth, easy to lose, and not beautiful. [0003] The other is a circular duct. The circular range hood ducts used in hot pot restaurants are not equipped with air volume adjustment switches. Contents of the invention [0004] In order to solve the above exist...
