Description

Technical Field

[0001] This utility model relates to the field of range hood suspension installation, and in particular to a suspension device for range hoods. Background Technology

[0002] Most range hoods are installed by hooks that are interlocked. One hook is fixed to the wall with expansion bolts or other fixing devices, while the other hook is located on the surface of the range hood. The hooks on both sides are interlocked to complete the hanging of the range hood.

[0003] However, in actual use, there may be a height difference that is not visible to the naked eye when the operator installs the hooks along the wall, which may cause the range hood to tilt after it is hung. If adjustment is needed, the hooks on the wall surface must be removed and the wall repaired. Then the installation position must be re-determined and the range hood re-installed. This process may require the operator to perform the operation repeatedly. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the purpose of this utility model is to solve the problem that once the hooks on the wall surface are fixed in position, adjustments are required, which necessitates the removal and re-fixing of the hooks by operators. This process damages the wall, necessitates wall repair, and extends the construction period.

[0005] To solve the problems of the prior art, the technical solution of this utility model is as follows: It includes a fixing plate, on the surface of which two sets of retaining rails are symmetrically arranged. Each set of retaining rails is slidably connected to a hook assembly. The bottom of each hook assembly is provided with a passive slider. The bottom of each passive slider abuts against an active slider. The bottom of each active slider is provided with a connecting seat. Each connecting seat is threadedly connected to a lead screw. The two lead screws are sleeved with mounting seats and connected to the fixing plate through the mounting seats.

[0006] Furthermore, the passive slider and the active slider are mutually adapted right-angled triangles, with a smooth and flat inclined surface on the opposite side. The passive slider and the active slider are combined to form a rectangular structure, ensuring that the active slider can drive the passive slider to move in the vertical direction through the inclined surface when it moves.

[0007] Furthermore, the active slider has two connecting seats at its bottom. The two connecting seats are respectively located on both sides of the bottom of the active slider and have threads on their inner walls, ensuring that when the lead screw rotates, the connecting seats drive the active slider to move horizontally under the action of the internal threads.

[0008] Furthermore, the passive sliders at the bottom of the two hook assemblies and the active sliders that abut against the passive sliders are both arranged in a facing position.

[0009] Furthermore, each lead screw has a mounting base that is fixedly connected to the fixing plate on one side near both ends. The mounting base is equipped with a bearing that is compatible with the lead screw to ensure that the lead screw will not be displaced during rotation and will always remain in the same position.

[0010] Furthermore, an internal hexagonal nut is provided at the opposite end of the two lead screws so that the operator can rotate the lead screw through the internal hexagonal nut.

[0011] Furthermore, the fixed plate has a limiting groove on the side near the active slider, and the active slider has a sliding protrusion extending into the limiting groove on the side near the limiting groove, so that the sliding protrusion is located in the limiting groove and moves with the active slider when it moves, thus limiting the active slider to always remain in a vertical state and not to rotate with the lead screw.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] This invention allows the operator to rotate a lead screw, which in turn moves the active slider connected to the lead screw via a connecting seat. When the active slider moves toward the edge of the fixed plate, the passive slider slides down. When the active slider moves toward the center of the fixed plate, the passive slider is pushed upward. During the vertical movement of the passive slider, the hook assembly at its top changes its height along the vertical direction, thereby adjusting the position of the hook assembly. This can be done without removing the entire assembly from the wall surface and without damaging the wall. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] like Figure 1-3As shown, a suspension device for a range hood includes a fixed plate 1. Two sets of rails 2 are symmetrically arranged on the surface of the fixed plate 1. Each set of rails 2 is slidably connected to a hook assembly 3. A passive slider 4 is provided at the bottom of each hook assembly 3. An active slider 5 is abutted at the bottom of each passive slider 4. The passive slider 4 and the active slider 5 are mutually adapted right-angled triangles. The opposite side is a smooth and flat inclined surface. The passive slider 4 and the active slider 5 are combined to form a rectangular structure, ensuring that the active slider 5 can drive the passive slider 4 to move in the vertical direction through the inclined surface when moving.

[0020] The passive slider 4 at the bottom of the two hook assemblies 3 and the active slider 5 that abuts against the passive slider 4 are both arranged in a facing state. Each of the two active sliders 5 is provided with a connecting seat 6 at the bottom. Each connecting seat 6 is threaded with a lead screw 7 inside. There are two connecting seats 6 at the bottom of the active slider 5. The two connecting seats 6 are respectively arranged on both sides of the bottom of the active slider 5 and the inner wall is provided with threads to ensure that when the lead screw 7 rotates, the connecting seat 6 drives the active slider 5 to move horizontally under the action of the internal threads.

[0021] Two lead screws 7 are fitted with mounting seats 8 and connected to the fixed plate 1 through the mounting seats 8. The two lead screws 7 are provided with hexagonal nuts at their opposite ends so that the operator can rotate the lead screws 7 through the hexagonal nuts. Each lead screw 7 is provided with a mounting seat 8 that is fixedly connected to the fixed plate 1 on one side near both ends. The mounting seat 8 is provided with a bearing that is compatible with the lead screw 7 to ensure that the lead screw 7 will not be displaced during rotation and will always remain in the same position. The fixed plate 1 is provided with a limiting groove on the side near the active slider 5. The active slider 5 is provided with a sliding protrusion that extends into the limiting groove on the side near the limiting groove. When the active slider 5 moves, the sliding protrusion is located in the limiting groove and moves with it, limiting the active slider 5 to always remain in a vertical state and will not rotate with the lead screw 7.

[0022] Working principle description: First, during use, the operator places the fixing plate 1 in the desired position on the wall using the fixing bolts. Then, when it is necessary to adjust the height of the hook assembly 3, the operator uses a hex wrench to turn the screw 7. When the screw 7 turns, it drives the active slider 5 to move towards the center or edge of the fixing plate 1.

[0023] When the active slider 5 moves toward the center of the fixed plate 1, the inclined surface of the active slider 5 and the inclined surface of the passive slider 4 interact to push the passive slider 4 upward. During the upward movement, the passive slider 4 drives the hook assembly 3 to move upward.

[0024] When the active slider 5 moves toward the edge of the fixed plate 1, the active slider 5 moves away from the passive slider 4. The passive slider 4 slides down while always keeping the inclined surface of the active slider 5 in contact. During the downward slide, the passive slider 4 drives the hook assembly 3 to move downward.

[0025] The range of movement of the two hook components 3 can be controlled by the operator, thereby allowing for position adjustment.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
