[0038] As Figures 1 to 6 shown, an embodiment of the present utility model provides a hook structure 100 for installing a wall-mounted device, such as a range hood 200. The hook structure 100 includes a fixed seat 10, a movable seat 20, and an adjusting assembly 30. Among them, the fixed seat 10 is provided with a first connection hole 121; the movable seat 20 is provided with a second connection hole 231, and an anti-rotation space 20a is formed on the movable seat 20; the adjusting assembly 30 includes an adjusting screw 31 and a fixing nut 32. The adjusting screw 31 passes through the first connection hole 121 and the second connection hole 231 in sequence and is threadedly connected to the fixing nut 32. The axial direction of the adjusting screw 31 is parallel to the vertical direction; the fixing nut 32 is located in the anti-rotation space 20a, and the anti-rotation space 20a can limit the rotation of the fixing nut 32. In this embodiment, a hook 22 is provided on the movable seat 20, and a hanging hole is provided on the range hood 200. The range hood 200 can be hung on the hook 22 through the hanging hole. Alternatively, other structures may also be provided on the movable seat 20 to fix the range hood, and this is not limited to this embodiment.

[0039] When installing the range hood 200, first fix the fixing base 10 to the wall, then hang the range hood 200 on the hook 22 of the movable base 20 through the hanging holes, and then rotate the adjusting screw 31. Since there is an anti-rotation space 20a on the movable base 20 to prevent the fixing nut 32 from rotating, the rotation of the fixing nut 32 is restricted when the adjusting screw 31 is rotated, so it is converted into a movement along the axis direction of the adjusting screw 31, further driving the movable base 20 to move along the axis direction of the adjusting screw 31, so as to achieve the purpose of adjusting the position of the hook 22 and the range hood 200, and then the gap between the range hood 200 and the top cabinet can be reduced or even eliminated.

[0040] By setting the hook structure 100 as a split fixing base 10 and movable base 20, and using the adjusting component 30 to connect the two, the relative position between the movable base 20 and the fixing base 10 can be adjusted, so as to adjust the position of the hook 22, and then the position adjustment of the range hood 200 can be realized, and the structure is simple and easy to operate.

[0041] Since the range hood 200 is heavy after being hung on the hook 22, in order to make the adjustment more labor-saving, a radial bearing 33 is arranged between the head of the adjusting screw 31 and the fixing base 10 in this embodiment. The radial bearing 33 is used to support the rotation of the adjusting screw 31, so as to change the sliding friction when the adjusting screw 31 rotates into rolling friction, and then it is more labor-saving to rotate the adjusting screw 31.

[0042] Furthermore, the adjusting component 30 further includes a locking nut 34. The locking nut 34 is threadedly connected to the adjusting screw 31, and the locking nut 34 and the fixing nut 32 jointly clamp the movable base 20. After rotating the adjusting screw 31 to adjust the hook 22 to a suitable position, then lock the locking nut 34 to fix the movable base 20.

[0043] Specifically, the fixing base 10 includes a first base body 11 and a first connecting plate 12 vertically connected to the first base body 11. A fixing hole 111 is arranged on the first base body 11, and the fixing base 10 is fixed to the wall through the fixing hole 111. Optionally, multiple groups of fixing holes 111 are arranged on the first base body 11. During the actual installation process, there may be structures such as wires or water pipes in the wall, and one or more groups can be selected from multiple groups of fixing holes 111 according to the actual situation for fixing, making the installation more flexible. The first connection hole 121 is arranged on the first connecting plate 12. The movable base 20 includes a second base body 21 and a second connecting plate 23 vertically connected to the second base body 21. The hook 22 is arranged on the second base body 21, and the second connection hole 231 is arranged on the second connecting plate 23. Through the above structural settings of the fixing base 10 and the movable base 20, it is convenient not only to fix the fixing base 10 to the wall, but also to connect the fixing base 10 and the movable base 20 by the adjusting component 30.

[0044] In this embodiment, the second seat body 21 is located on the side of the first seat body 11 away from the first connecting plate 12, and the first seat body 11 is provided with an avoidance hole 112, and the second connecting plate 23 extends to the side of the first seat body 11 where the first connecting plate 12 is provided through the avoidance hole 112. In addition, a groove is provided on the side of the first seat body 11 away from the first connecting plate 12, and the second seat body 21 is movably provided in the groove, and the side of the second seat body 21 away from the second connecting plate 23 does not protrude from the side of the first seat body 11 away from the first connecting plate 12, so as to prevent the first seat body 11 from affecting the movement of the movable seat 20 after being fixed to the wall. When the first base body 11 is fixed to the wall, the side of the first base body 11 facing away from the first connecting plate 12 is in contact with the wall. By arranging the second base body 21 on the side of the first base body 11 facing away from the first connecting plate 12 and arranging a groove for accommodating the first base body 11 on the side of the first base body 11 facing away from the first connecting plate 12, the fixed contact area between the first base body 11 and the wall can be ensured, and the position adjustment of the movable base 20 will not be affected, and the overall structural layout is more reasonable.

[0045] Furthermore, the groove is formed by the side of the first base body 11 facing away from the first connecting plate 12 and concave toward the side where the first connecting plate 12 is provided, and at the same time, a protrusion 113 is formed on the side where the first connecting plate 12 is provided on the first base body 11, so that the structural strength of the first base body 11 can be ensured. Furthermore, a reinforcing rib 114 is provided on the protrusion 113 formed on the side where the connecting plate is provided on the first base body 11, and the reinforcing rib 114 is provided on the peripheral side of the avoidance hole 112 to further ensure the structural strength of the first base body 11.

[0046] Further, the first connecting plate 12 is provided with a plurality of first connecting holes 121, which are spaced apart along a first direction, the first direction being parallel to the left-right direction of the range hood 200, and the adjusting screw 31 is selectively inserted into the first connecting hole 121. Through the above arrangement, the position adjustment of the movable seat 20 along the first direction (i.e., along the left-right direction of the range hood 200) can be realized to avoid interference with components on the range hood 200 (e.g., the top air outlet 201). Alternatively, the first connecting hole 121 can also be a waist-shaped hole, which extends along the first direction, and the adjusting screw 31 is inserted into the waist-shaped hole, which can also realize the position adjustment of the movable seat 20 along the first direction, and is stepless adjustment. It should be noted that the length of the avoidance hole 112 along the first direction is not less than the length of the plurality of first connecting holes 121 along the first direction or the length of the waist-shaped hole along the first direction, so as to ensure the space for the movable seat 20 to move left and right.

[0047] In this embodiment, two support plates 13 are arranged at the lower end of the first connecting plate 12 at intervals, and the support plates 13 are connected to the first seat body 11. By arranging the support plates 13, the structural strength of the first connecting plate 12 is enhanced. Further, a folding plate 14 is arranged at one end of the support plate 13 for connecting the first seat body 11, and the folding plates 14 on the two support plates 13 are arranged oppositely and connected to the first seat body 11, that is, the support plate 13 is connected to the first seat body 11 through the folding plate 14, further enhancing the structural strength of the first connecting plate 12.

[0048] In this embodiment, the fixed seat 10 is of an integral structure, which is formed by bending a metal flat plate material, can improve the overall structural strength, and has a lower cost. Of course, the structural form of the fixed seat 10 is not limited to this, and the fixed seat 10 can also be a split structure and then connected by means of welding, fastener connection, etc.

[0049] In this embodiment, a stepped structure 211 is arranged on the second seat body 21 to enhance the structural strength of the second seat body 21. Optionally, the stepped structure 211 is obtained by stamping the part of the second seat body 21 around the stepped structure 211.

[0050] In this embodiment, two turning plates 24 are arranged at the lower end of the second connecting plate 23 at intervals, and the second connecting plate 23 and the two turning plates 24 jointly enclose an anti-rotation space 20a, which can not only prevent the fixing nut 32 from rotating, but also ensure the structural strength of the second connecting plate 23. In this embodiment, the fixing nut 32 is non-circular and can be polygonal to facilitate the restriction of the rotation of the fixing nut 32.

[0051] Further, a reinforcing plate 25 is covered on the second connecting plate 23 and the turning plate 24, the reinforcing plate 25 is connected to the second seat body 21 through a reinforcing rib 26, and a through hole 251 is arranged on the reinforcing plate 25 opposite to the second connecting hole 231 for the adjusting screw 31 to pass through. Through the above settings, the structural strength at the second connecting plate 23 can be improved, so as to provide sufficient strength support after the hook 22 is hooked on the range hood 200.

[0052] In this embodiment, the moving seat 20 is of an integral structure, which is formed by bending a metal flat plate material, can improve the overall structural strength, and has a lower cost. Of course, the structural form of the moving seat 20 is not limited to this, and the moving seat 20 can also be a split structure and then connected by means of welding, fastener connection, etc.

[0053] Obviously, the above-mentioned embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model.
