[0003] The processing of the existing filter outer frame is all done using traditional process flow; it is completed through multiple processes such as cutting, corner cutting, forming, punching, and riveting. The horizontal frame and the vertical frame have different structures and need to be designed and processed separately. There are disadvantages such as long processing cycle, large dimensional deviation, and the edges of the filter outer frame cannot be interchanged. Utility Model Content
[0004] The utility model aims to provide a novel filter outer frame with a short processing period and interchangeable sides.

[0014] The horizontal outer frame and the vertical outer frame are fixedly connected.
[0015] Furthermore, the first bottom surface and the second bottom surface are respectively provided with reinforcing ribs.
[0016] Furthermore, the first bottom surface and the second bottom surface are concave with two grooves toward the inner side of the rectangular frame to form the reinforcing ribs, and the length of the grooves is set along the length of the first bottom surface and the second bottom surface.
[0017] Furthermore, a first sealing groove is provided on a surface of the first side surface perpendicular to the first bottom surface, and the first sealing groove is used to accommodate a first sealing strip;

The filter frame's sides are interchangeable, significantly improving efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.
[0034] It should be noted that the terms "above", "one end", "upper", etc. used in this article indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. Similar expressions are only for illustrative purposes, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention; in addition, the terms "one part", "two parts", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance.
[0035] like Figure 5-7 The novel filter outer frame shown in the figure comprises two opposite horizontal outer frames and two opposite vertical outer frames which can be assembled into a rectangular frame. The horizontal outer frames and the vertical outer frames are arranged alternately.
[0036] The transverse outer frame includes a first bottom surface 1 , two first side surfaces 2 arranged opposite to each other at the width ends of the first bottom surface 1 , and a first mounting plate 3 arranged at one length end of the first bottom surface 1 .
[0037] The first side surface 2 is a 90° bent plate structure and is fixed perpendicularly to the first bottom surface 1. The transverse cross-section of the transverse outer frame is a rectangular shape with an open edge, the edge of which is opposite to the first bottom surface 1. The first side surface 2 and the first bottom surface 1 can be integrally formed by bending the entire steel plate.
[0038] The first mounting plate 3 is perpendicular to the first bottom surface 1 ; the first mounting plate 3 and the first bottom surface 1 can be formed as one piece, and both are formed by bending the entire steel plate.
[0039] The vertical outer frame includes a second bottom surface, two second side surfaces arranged oppositely at both ends of the width of the second bottom surface, and a second mounting plate arranged at one end of the length of the second bottom surface; the structure of the vertical outer frame is the same as that of the horizontal outer frame, but the length size can be the same or different according to the requirements of the outer frame, and the width of the first bottom surface and the second bottom surface is the same.
[0040] The second side surface is a 90° bent plate structure and is fixed perpendicularly to the second bottom surface.
[0041] The second mounting plate is perpendicular to the second bottom surface.
[0042] The first side surface 2 is cut off at an angle at both ends, and the second side surface is cut off at a corresponding angle at both ends, so that the cross-sections of the first and second side surfaces can be seamlessly joined. When seamlessly joined, the first mounting plate 3 abuts the second bottom surface, and the second mounting plate abuts the first bottom surface. Specifically, the first mounting plate 3 of the horizontal outer frame abuts the second bottom surface of the vertical outer frame, the second mounting plate of the vertical outer frame abuts the first bottom surface of another horizontal outer frame, and the second mounting plate of another horizontal outer frame abuts the first bottom surface of another vertical outer frame. The second mounting plate and the first mounting plate 3 serve as positioning devices. The widths of the first mounting plate 3 and the second mounting plate are less than the widths of either the first or second bottom surfaces.
[0043] Preferably, the cross-sections of the first side surface and the second side surface are 45° respectively, and 45° with the first bottom surface or the second bottom surface.
[0044] The horizontal outer frame and the vertical outer frame can be fixedly connected by connecting pieces or welding.
[0045] Preferably, in order to enhance the strength of the horizontal outer frame or the vertical outer frame, the first bottom surface 1 and the second bottom surface are respectively provided with reinforcing ribs.
[0046] Specifically, the first bottom surface 1 and the second bottom surface are concave with two grooves toward the inner side of the rectangular frame to form reinforcing ribs, and the length of the grooves is set along the length of the first bottom surface 1 and the second bottom surface. This increases the strength of each side of the filter and makes the surface look more beautiful.
[0047] In order to better install the sealing strip, a first sealing groove is provided on a surface of the first side surface 2 perpendicular to the first bottom surface 1 , and the first sealing groove is used to accommodate the first sealing strip.
[0048] A second sealing groove is provided on the second side surface, perpendicular to the second bottom surface, to accommodate a second sealing strip. Specifically, two U-shaped grooves are added to the filter thickness to serve as the first or second sealing grooves, providing a reference for bonding the sealing strip to the outer frame. The shape of the U-shaped grooves matches the sealing strip, enhancing its fit and achieving a superior sealing effect.
[0049] Preferably, the horizontal outer frame and the vertical outer frame are fixed by rivets provided on the first mounting plate 3 and the second mounting plate. Figure 6 As shown, there are two rivets on the first mounting plate, which can both accurately position the filter and increase the stability of the filter frame.
[0050] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
