When the range hood works (or is used), the hanging plate frame 10 is installed on a wall, then the body 201 of the range hood is installed on the installation rod 23, when the height of the range hood needs to be adjusted, the control frame 40 is pulled downwards, two ends of the control frame 40 respectively drive the transmission belt 3153 to rotate, in the rotation process of the transmission belt 3153, the bevel gear 3152 and the transmission belt 3153 rotate in the same direction and drive the first vertical long rod 314 and the second vertical long rod 324 to rotate through the bevel gear 3151, the first pulley 3121 on the first vertical long rod 314 winds the first transmission rope 3122 on the surface thereof, at this time, the first fixture block 311 moves towards the second position under the action of the first transmission rope 3122 and compresses the first elastic member 313, meanwhile, the second pulley 3221 on the second vertical long rod 324 winds the second transmission rope 3222 on the surface thereof, at this time, the second fixture block 321 moves towards the second position under the action of the second transmission rope 3222 and compresses the second elastic member 323, when the first fixture block 311 is completely moved out of the bottom of the first positioning block 235 and the second fixture block 321 is completely moved out of the bottom of the second positioning block 236, the adjusting knob 21 is rotated again, the adjusting knob 21 drives the first threaded rod 223 and the second threaded rod 224 to rotate in the same direction, the first connecting section 231 and the second connecting section 232 move in the same direction under the action of the first threaded rod 223 and the second threaded rod 224, after the position of the range hood is adjusted, the control frame 40 is loosened first, the first fixture block 311 automatically resets under the action of the first elastic member 313 to fix the first fixture block 235 between the two first fixture blocks 311, the second fixture block 321 automatically resets under the action of the second elastic member 323 to fix the second positioning block 236 between the two second fixture blocks 321, the adjusting knob 21 is loosened, the whole range hood is fixed completely, and if other heights need to be adjusted, the operations are repeated. It is worth noting that in the embodiment, due to the fact that different range hoods are different in weight, the adjusting knob 21 cannot be rotated manually, and an operator can drive the adjusting knob 21 to rotate through the motor to fix the height of the range hood.

The utility model discloses an among the lampblack absorber, through the first threaded rod 223 of adjust knob 21 control, thereby second threaded rod 224 rotates the regulation and installs the lampblack absorber height on installation pole 23, and can use first fixture block 311 after the regulation, second fixture block 321 is respectively to first locating piece 235, the position of second locating piece 236 is fixed, prevent that the lampblack absorber from taking place the vibration and leading to first threaded rod 223 in the use, second threaded rod 224 rotates and produces the influence to the lampblack absorber position, also can greatly reduce simultaneously because lampblack absorber gravity is to first threaded rod 223, the pressure of screw thread on the second threaded rod 224, prevent first threaded rod 223, the screw thread damage on the second threaded rod 224 and lead to the lampblack absorber unable regulation and fixed.

In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the orientation words such as "upper", "lower", etc. is usually based on the orientation or positional relationship shown in the drawings, and is only for convenience of description and simplification of description, and in the case of not making a contrary explanation, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be interpreted as limiting the scope of the present invention; the terms "inner and outer" refer to the inner and outer relative to the profile of the respective component itself.

Spatially relative terms, such as "above … …," "above … …," "above … …," "above," and the like, may be used herein for ease of description to describe the spatial relationship of one or more components or features shown in the figures to other components or features. It is to be understood that the spatially relative terms are intended to encompass not only the orientation of the component as depicted in the figures, but also different orientations of the component in use or operation. For example, if an element in the drawings is turned over in its entirety, the articles "over" or "on" other elements or features will include the articles "under" or "beneath" the other elements or features. Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". Further, these components or features may also be positioned at various other angles (e.g., rotated 90 degrees or other angles), all of which are intended to be encompassed herein.
