Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of filters, in particular to an X-bracket foldable and shrinkable filter. Background Art
[0002] There is a filter in the air purifier. The filter part used by Aprilaire in business, such as the filter in the 1210 machine, uses arc-shaped hooks at the upper and lower ends to hang on the slide rail to form a suspension technology, which also blocks the lateral movement of the filter. The height of the entire filter is not fixed and is adjusted according to the arc-shaped hooks at the upper and lower ends to fix it in the frame, resulting in poor structural stability. Utility Model Content
[0003] One purpose of the utility model is to provide an X-bracket foldable shrink filter, which adopts the foldable form of the X-bracket to determine the height, the door-shaped protrusion ensures the sealing, and the porous position on the X-bracket is height-adjustable.
[0004] To achieve this purpose, the present invention adopts the following technical solutions:
[0005] An X-bracket foldable and shrinkable filter comprises a filter frame, a foldable filter screen and two mounting profiles, wherein the two mounting profiles are respectively located at the upper and lower ends of the foldable filter screen, and a door-shaped protrusion is formed on the mounting profile, and the door-shaped protrusion contacts the inner side of the filter frame. Adjustment support strips are provided on the sides of the two mounting profiles, and the two adjustment support strips are hinged in the middle position in a cross form to form an X-bracket, and the upper end of the adjustment support strip is screwed to the mounting profile above, and the lower end of the adjustment support strip is screwed to the mounting profile below.
[0006] As a preferred technical solution, the material of the mounting profile is plastic.
[0007] As a preferred technical solution, side barrier strips are formed on both sides of the installation profile, and the upper and lower ends of the foldable filter are located between the side barrier strips on both sides.
[0008] As a preferred technical solution, a plurality of holes are symmetrically arranged on the mounting profile.
[0009] As a preferred technical solution, one side of the filter frame is a sealing plate, and the other side of the filter frame is provided with a filter screen inlet, and the filter screen inlet is covered with a sealing cover.
[0010] The beneficial effects of the utility model are: providing an X-bracket foldable shrink filter, which can prevent lateral movement during use, and the protrusions of the profile play a sealing role. The angle between the support bars on the X-bracket can be adjusted to meet the filter sizes of different models, and the adaptability is strong. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.
[0018] like Figures 1 to 3 As shown, in this embodiment, an X-bracket foldable and shrinkable filter includes a filter frame 1, a foldable filter screen 2 and two mounting profiles 3. The two mounting profiles 3 are respectively located at the upper and lower ends of the foldable filter screen 2. A door-shaped protrusion 4 is formed on the mounting profile 3. The door-shaped protrusion 4 contacts the inner side of the filter frame 1. Adjustment support strips 5 are provided on the sides of the two mounting profiles 3. The two adjustment support strips 5 are hinged in the middle position in a cross form to form an X-bracket 6. The upper end of the adjustment support strip 5 is screwed to the upper mounting profile 3, and the lower end of the adjustment support strip 5 is screwed to the lower mounting profile 3.
[0019] When the filter frame 1 is empty inside, the foldable filter screen 2 is prevented from being placed between the upper and lower mounting profiles 3. The upper end of the foldable filter screen 2 is on the upper mounting profile 3, and the lower end of the foldable filter screen 2 is on the lower mounting profile 3. The upper and lower mounting profiles 3 are located at the upper and lower ends of the filter frame 1. For filters of different heights, the hinge angle between the two adjustment support bars 5 can be changed, thereby changing the distance between the two mounting profiles 3. Correspondingly, the position of the adjustment support bar 5 locked on the mounting profile 3 also changes.
[0020] Under the action of the door-shaped protrusion 4, the installation profile 3 will not move laterally when wind enters, thus playing a sealing role.
[0021] The mounting profile 3 is made of plastic, and side barrier strips 7 are formed on both sides of the mounting profile 3. The upper and lower ends of the foldable filter screen 2 are located between the side barrier strips 7 on both sides, and the foldable filter screen 2 is located between the side barrier strips 7 and will not fall off.
[0022] Several holes 8 are symmetrically arranged on the mounting profile 3. The length of the adjustment support strip 5 used is 612 mm, the width of the adjustment support strip 5 is 15 mm, the length of the mounting profile 3 is 640 mm, the distance between the center of the outermost hole 8 and the end of the mounting profile 3 is 152.75 mm, the center distance between two adjacent holes 8 is 7.25 mm, and the edge distance between two adjacent holes 8 is 3.25 mm.
[0023] One side of the filter frame 1 is a sealing plate 9, and the other side of the filter frame 1 is provided with a filter screen inlet, which is covered with a sealing cover 10. The foldable filter screen 2 is placed into the filter frame 1 from the filter screen inlet, and then covered with the sealing cover 10 to maintain the stability of the overall structure.
[0024] It should be stated that the above-mentioned specific implementation methods are only preferred embodiments of the present invention and the technical principles used. Within the technical scope disclosed by the present invention, any changes or replacements that can be easily thought of by technicians familiar with this technical field should be included in the scope of protection of the present invention.
