In this embodiment, the fixed member 1 and the movable member 2 are in a relatively movable relationship. The fixture 1 may be fixedly connected to a load-bearing structure, such as a wall of a kitchen. The moving member 2 is used for being connected with a range hood to drive the range hood to move along the mounting height direction of the range hood, the moving direction of the moving member 2 (the mounting height direction of the range hood) is the direction in which the fixing member 1 and the moving member 2 are relatively close to each other, for example, the fixing member 1 is fixed on a wall body in vertical arrangement, and the mounting height direction of the range hood is vertical upwards to adjust the height of the range hood.

The limiting part 3 moves along the mounting height direction of the range hood synchronously with the moving part 2, and moves between the limiting position and the avoiding position in the stage of moving along the mounting height direction of the range hood.

The guide portion 11 is not connected to the stopper 3 at the stage of moving the stopper 3 to the stopper position, and when the stopper 3 is positioned at the stopper position, the next guide portion 11 is opposed to the sliding surface 1. The supporting portion 12 is used for supporting the limiting member 3 to limit the movement of the limiting member 3, so as to prevent the moving member 2 and the fixing member 1 from falling off, and achieve anti-falling.

The end of the spacing element 3 remote from the fixing element 1, i.e. the forward end of the spacing element 3, is provided with a projection extending radially along the spacing element 3, which projection serves as a spacing structure 33. The top of the limiting member 3, which is close to one end of the fixing member 1, i.e., the rearward end of the limiting member 3, is provided with an inclined interference surface which is inclined downward toward the fixing member 1, i.e., rearward and downward, as an inclined sliding surface 32; the bottom has an arc-shaped surface, i.e. the side of the limiting member 3, for abutting against the supporting portion 12 of the fixing member 1 under the action of gravity.

The locking member 5 includes a threaded rod and a rod head provided at an end of the threaded rod. The threaded rod is the rod-shaped structure 51, and the club head is the abutting structure 52. In the screw axis direction, the projection of the head covers the projection of the threaded rod. The outer edge of the threaded rod is provided with a threaded rod which is arranged vertically and which is connected with the connecting plate 21 of the moving part 2 through the first plate 14 of the fixed part 1, the threaded rod being movable in the vertical direction.

In order to further understand the height adjusting device of the range hood provided by the embodiment of the application, the installation and adjustment process of the height adjusting device of the range hood is specifically described below.

Under the condition that the mounting seat 24 is not mounted, the threaded rod is rotated anticlockwise, the moving part 2 moves downwards to the lowest position, then the mounting seat 24 is mounted, at the moment, the limiting part 3 is located at the limiting position, one end of the limiting part 3 stretches into the limiting hole 13 at the lowest end, and the limiting part 3 is abutted with the supporting part 12, so that the assembly of the range hood height adjusting device is completed.

4 holes with the diameter of about 10 mm and the depth of about 80 mm are drilled in the kitchen wall, expansion pipes are plugged into the holes, and 2 two range hood height adjusting devices are fixed on the wall by using wood screws. And then, fixing the assembled range hood height adjusting device on a wall body by using bolts, and hanging the range hood on the hook 23 of the moving part 2, wherein the top of the range hood is at a distance of 35-40 mm from the lower end of the cabinet 6.

The left lower corner or the right lower corner of the bottom of the range hood is lifted by hands, and the range hood is lifted slightly upwards to drive the moving part 2 to move upwards vertically. In the vertical upward stage of the stopper 3, the inclined interference surface comes into contact with the guide portion 11 of the fixing member 1 from the top, and the guide portion 11 pushes the stopper 3 to move forward from the stopper position. In the pushing process, the spring is compressed to accumulate elastic potential energy, the guide part 11 slides along the interference surface from the top of the interference surface to the bottom of the interference surface, the limiting piece 3 correspondingly reaches the avoiding position, then the end part of the limiting piece 3, which is close to the fixing piece 1, continues to move upwards, passes through the communication part of the two circular limiting holes 13 and then stretches into the next limiting hole 13, and the spring releases the accumulated elastic potential energy to push the limiting piece 3 to move from the avoiding position to the limiting position, namely to move to the rear side. The limiting piece 3 is abutted with the supporting part 12 of the next round limiting hole 13, and meanwhile the moving piece 2 drives the threaded rod to move upwards synchronously.

The above is the process of moving the moving member 2 from one circular limiting hole 13 to the next circular limiting hole 13.

After the range hood is moved to a proper height, the limiting piece 3 is abutted against the supporting part 12 so as to fix the relative positions of the moving piece 2 and the fixing piece 1, and the pre-fixing is realized. Then, the threaded rod is rotated clockwise to descend to the lowest position capable of moving, so that the bottom of the abutting structure 52 abuts against the top of the first plate 14 of the fixed part 1, the threaded rod is tightly connected with the connecting plate 21 of the moving part 2 in a threaded mode, so that the moving part 2 is tensioned, the limiting part 3 is not supported by the fixed part 1 any more, even the limiting part 3 is not contacted with the supporting part 12 of the fixed part 1 any more, and the force for keeping the range hood at the current height is the tensioning force of the threaded rod.

After one side of the range hood is adjusted, the other side is adjusted by the same method, so that the range hood reaches the level and is close to the lower end face of the cabinet 6. The adjustment of the moving member 2 in the vertically upward direction is a one-way adjustment, and if the height of the range hood is adjusted in the vertically downward direction, the mounting seat 24 needs to be removed, and the moving member 2 is lowered.

Details of the range hood height adjustment device are next supplemented. The top of the third plate 16 of the fixture 1 is also provided with a spring positioning cylinder 19, which spring positioning cylinder 19 has a downwardly concave recess, the opening of which recess is upwards and corresponds to the threaded rod. The range hood height adjusting device further comprises a hook spring 7, and the hook spring 7 is sleeved on the outer side of the pre-threaded rod. The hooking spring 7 comprises an upper end portion, which is located between the third plate 16 of the fixed member 1 and the connecting plate 21 of the movable member 2, and a lower end portion, which is located between the connecting plate 21 of the movable member 2 and the first plate 14 of the fixed member 1. Wherein, the bottom end of the lower section is arranged in the spring positioning cylinder 19. The lower end part is used for providing the elastic force for the upward movement of the moving part 2 and the downward buffering force through the connecting plate 21 acting on the moving part 2; the upper end portion is provided with an elastic force for downward movement of the moving member 2 and an upward buffering force by a connection plate 21 acting on the moving member 2.
