Description

Technical Field

[0001] An adjustable range hood filter cover that can be installed on a range hood and whose length, width, and height can be adjusted to accommodate range hoods of different installation sizes. Background Technology

[0002] Most existing range hood filter covers are not compatible with range hoods of different installation lengths, widths, and heights, causing great inconvenience in the installation and use of range hood filter covers. Summary of the Invention

[0003] To overcome the above-mentioned defects, the purpose of this utility model is to provide an adjustable range hood filter cover.

[0004] To achieve the above objectives, this utility model provides an adjustable range hood filter cover, comprising: a 7-type horizontal arm, an upper hanging rod, a lower hanging rod, and a base. One side of the 7-type horizontal arm has a horizontal arm groove, and a horizontal arm set screw nut is provided on the outer side of the horizontal arm groove. The set screw is screwed into the set screw nut and extends into the horizontal arm groove. The other side of the 7-type horizontal arm is equipped with a horizontal arm slide rail, allowing one 7-type horizontal arm's slide rail to slide into the horizontal arm groove of another 7-type horizontal arm. The middle part of the 7-type horizontal arm has a bolt fixing hole and an upper hanging rod hook hole. The upper end of the upper hanging rod has an upper hanging rod hook, and the lower end has a hanging rod groove. A hanging rod set screw nut is provided on the outer side of the hanging rod groove, allowing the set screw to screw into the set screw nut and extend into the hanging rod groove. The upper end of the lower hanging rod is equipped with a hanging rod slide rail, which slides into the hanging rod groove. The lower end of the lower hanging rod has a lower hanging rod hook. The base has a lower hanging rod hook hole, an oil cup retainer, and an oil leakage hole.

[0005] Furthermore, screw the cross arm set screw into the cross arm set screw nut, the head of which presses against the inserted cross arm slide rail, and use the friction force of the contact after pressing to fix the four 7-type cross arms together; by adjusting the insertion depth of the cross arm slide rail, the length and width of the adjustable range hood filter screen cover can be adjusted to adapt to range hoods with different installation lengths and widths.

[0006] Furthermore, screw the mounting screw into the mounting screw nut, and its head presses against the mounting rail. The friction of the contact after pressing together fixes the upper and lower mounting rods together. By adjusting the insertion depth of the mounting rail, the height of the adjustable range hood filter cover can be adjusted to adapt to range hoods installed at different heights.

[0007] Furthermore, hook the lower hanging rod hook into the lower hanging rod hook hole, hook the upper hanging rod hook into the upper hanging rod hook hole, and tighten the hanging rod set screw at the same time to fix the upper hanging rod and the lower hanging rod together. This will fix the type 7 cross arm, the upper hanging rod, the lower hanging rod and the base together.

[0008] When in use, the adjustable range hood filter cover is fixed to the range hood by bolts through the bolt fixing holes. The length and width of the range hood filter cover are adjusted by adjusting the insertion depth of the horizontal arm slide rail, and the height of the range hood filter cover is adjusted by adjusting the insertion depth of the hanging rod slide rail. This allows it to be installed on range hoods with different installation lengths, widths, and heights. Attached Figure Description
