[0021] The technical solution of the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] As Figure 1 shown, the horizontal adjustment hanger of the present utility model adjusts the position of the range hood hung thereon by means of horizontal adjustment. The hanger includes a hanging plate 1 installed on the wall, and a hook 2 provided on the hanging plate 1 and having a hook portion. The hook 2 is located at the lower end of the hanging plate 1. The hanging plate 1 can be a frame structure, and a limiting end matching the hook 2 is provided on the bracket at its lower end. Or the hanging plate 1 can be a U-shaped structure, and limiting ends 8 matching the hook 2 are provided on both sides of its lower end extending inwards.

[0023] The hanger further includes an adjustment mechanism for driving the hook 2 to move up and down. That is, through the adjustment mechanism, not only the support of the hook 2 is realized, but also its up and down movement can be realized, and finally the position of the range hood is adjusted. The adjustment mechanism includes a horizontally arranged threaded rod 3, and a connecting plate 4 located on the threaded rod 3 that can move towards or away from each other by the rotation of the threaded rod 3. A locking nut 9 for tightening the threaded rod 3 is also provided at the tail end of the threaded rod 3 to lock the threaded rod 3 after reaching the preset position. And the threaded rod 3 and the connecting plate 4 are arranged in a non-contact connection with the hanging plate 1.

[0024] The movement modes of the connecting plate 4 and the threaded rod 3 can be realized through the following two major structural modes. One of the major categories is that the rotation of the threaded rod 3 drives the two connecting plates 4 to rotate, realizing their movement towards or away from each other. That is, relative to the threaded rod 3, the two connecting plates 4 both move left and right. This structure can include the following four structural modes:

[0025] The first structure is that the thread provided on the threaded rod 3 can be composed of two threads with different helix directions, that is, including a left-handed thread and a right-handed thread. Two connecting plates 4 that can move towards or away from each other with the rotation of the threaded rod 3 are respectively provided at the positions of the left-handed thread and the right-handed thread on the threaded rod 3, and nuts 10 matching the threaded rod 3 are fixedly provided on the inner side walls of the connecting plates 4, that is, a lead screw drive mode with different rotations is formed.

[0026] The second structure is that the thread provided on the threaded rod 3 can be composed of two threads with different helix directions, that is, including a left-handed thread and a right-handed thread. Two connecting plates 4 that can move towards or away from each other with the rotation of the threaded rod 3 are respectively provided at the positions of the left-handed thread and the right-handed thread on the threaded rod 3, and the contact positions of the connecting plates 4 with the threaded rod 3 are arranged in a thread shape matching the threaded rod 3, that is, a lead screw drive mode with different rotations is formed.

[0027] The third structure is that two nuts 10 matching with the threaded rod 3 are fixedly provided on the inner side wall of the connecting plate 4, and the two nuts 10 are respectively a left-handed nut and a right-handed nut, that is, the threads with different rotation directions on the threaded rod 3 are replaced by the different rotation directions of the nuts 10, so that the connection plate 4 can move towards or in the opposite direction by the rotation of the threaded rod 3.

[0028] The fourth structure is that the contact and matching parts between the connecting plate 4 and the threaded rod 3 are set to have thread structures with different rotation directions, namely left-handed thread and right-handed thread, and then the two connecting plates 4 can move towards or in opposite directions through the matching of the threads with different rotation directions.

[0029] The second type of movement is actually achieved through the relative movement of the connecting plate 4 away from the nut end of the threaded rod 3, while the movement of the connecting plate 4 close to the nut end of the threaded rod 3 is limited by the horizontal movement distance relative to the threaded rod 3 to avoid the generation of the same-direction movement of the two connecting plates 4. That is, it includes the following structural methods:

[0030] The first structure is that the connecting plate 4 near the nut end of the threaded rod 3 is limited by a limiting piece located on its inner side and fixed on the threaded rod 3, and a nut 10 matching the threaded rod 3 is fixed on the inner wall of the other connecting plate 4. Therefore, during the movement, the connecting plate 4 near the nut end is actually restricted in movement relative to the threaded rod 3, that is, through the forward or reverse rotation of the threaded rod 3, the connecting plate 4 away from the nut end of the threaded rod 3 is able to move closer to or farther from the connecting plate 4 near the nut end of the threaded rod 3.

[0031] The second structure is that the connecting plate 4 near the nut end of the threaded rod 3 is limited by a limiting piece located on its inner side and fixed on the threaded rod 3, and the end face of the other connecting plate 4 connected to the threaded rod 3 is a threaded surface that matches the threaded rod 3, so that the movement of the connecting plate 4 approaching or moving away can be achieved through the rotation of the threaded rod 3.

[0032] Regardless of the first structure or the second structure in the second category, the limiting member used can be a limiting pin or a limiting nut 11, and the limiting pin or the limiting nut 11 can be fixed on the threaded rod 3 by welding and located on the inner side of the connecting plate 4, such as Figure 2 shown.

[0033] The movement of the threaded rod 3 and the connecting plate 4 of the adjustment mechanism realizes horizontal movement toward or in the opposite direction to finally link the vertical movement of the hook 2, and the formation of this movement mode also benefits from the movable connecting rod assembly provided on the connecting plate 4. The movable connecting rod assembly is a connecting rod mechanism composed of two upper groups of connecting rods 5 and two lower groups of connecting rods 6. Through this connecting rod mechanism, not only can the adjustment mechanism be fixedly supported, but also the hook 2 can be linked to move up and down through this connecting rod mechanism. A connecting plate 7 for connecting with the adjustment mechanism is extended at the upper end bracket of the hanging plate 1 and the upper end of the hook 2. Among them, one end of the upper two groups of connecting rods 5 is rotatably connected to the connecting plate 7 extending from the hanging plate 1, and the other end is rotatably connected to the two connecting plates 4 respectively. One end of the lower two groups of connecting rods 6 is rotatably connected to the connecting plate 7 extending from the hook 2, and the other end is rotatably connected to the two connecting plates 4 respectively.

[0034] like Figure 3 and Figure 4 As shown, by rotating the threaded rod 3, based on the movement mode of the two connecting plates 4 on the threaded rod 3, under the drive of the movable connecting rod mechanism, when the threaded rod 3 is rotated to realize the two connecting plates 4 moving toward each other, the hook 2 is driven to move downward; when the threaded rod 3 is rotated to realize the two connecting plates 4 moving in the opposite direction, the hook 2 is driven to move upward, and finally the height position adjustment of the hung range hood is realized.
