Description

Technical Field

[0001] The present invention relates to a frame structure, particularly a filter frame used for attaching a filter and having a clamp structure.

Background Art

[0002] As shown in the specification of Taiwan Patent Application Publication No. 202511677, a prior art filter, particularly a corrugated folded filter, is usually fixed to a frame, and then the frame is fixed to a mounting seat of a filter device. The frame is a rectangular frame composed of two long frame bars and two short frame bars. The inner ring side surface of the frame is grooved. The method of combining the filter and the frame is to install the filter on the frame and apply an adhesive between the filter and the frame for adhesion.

[0003] However, when the filter is placed inside the frame, the gap between the filter and the frame becomes very small, making the adhesion process difficult. For example, to apply the adhesive smoothly, it is necessary to insert an adhesive nozzle into the gap between the filter and the frame. However, during the insertion process, the filter and the frame are compressed, and damage, deformation, and even adhesive overflow are likely to occur. Therefore, it is necessary to improve the above problems and drawbacks.

[0006] To achieve the object of the above invention, the technical means employed by the present invention is to design a filter frame having a clamp structure used for fixing a filter, and the filter frame having the clamp structure is A frame structure having opposing front and rear surfaces, Two clamp members are installed on the inner ring sides of the left and right sides of the frame structure, Includes, Multiple side walls are formed on the inner ring side surface of the frame structure, and each of the side walls protrudes from the frame structure and is adjacent to the front side surface and the rear side surface, respectively. The two clamping members are used to clamp the filter, which is placed within the frame structure. Each clamp member has a clamp sheet which is an elastic sheet, and the clamp sheet is bent toward the direction of the frame structure and works together with the frame structure to clamp the filter. ru.

[0007] More specifically, in the filter frame having the clamp structure, each clamp member has a connecting sheet and a clamp sheet, one end of the clamp sheet is coupled to the connecting sheet, the connecting sheet is fixed to the frame structure, and the clamp sheet maintains a certain distance from the frame structure.

[0008] More specifically, the filter frame having the clamp structure includes two long frame bars and two short frame bars, the two long frame bars and the two short frame bars being connected to each other to form a rectangular frame, the connecting sheet of each clamp member being fixed to one of the short frame bars and adjacent to the front surface of the frame structure, and the other end of the clamp sheet extending toward the rear surface.

[0009] More specifically, the filter frame having the clamp structure comprises two long frame bars and two short frame bars, the two long frame bars and the two short frame bars being connected to each other to form a rectangular frame, each short frame bar having a fixing sheet, the fixing sheet being located on a side wall adjacent to the front side of the frame structure and extending toward the rear side, each clamp member having a clamp sheet, one end of the clamp sheet of each clamp member being fixed to one of the fixing sheets, and the other end of the clamp sheet extending toward the rear side.

[0010] More specifically, the filter frame having the clamp structure further includes a plurality of position regulating plates, each of which has at least one through-hole, each of which is installed on the inner ring side of the frame structure, and the through-hole is adjacent to the side wall on the same side.

[0011] Furthermore, in the filter frame having the clamp structure, the through holes in each of the position regulating plates are elongated and there are multiple such holes, which extend along the length direction of each position regulating plate and are arranged at intervals.

[0012] Furthermore, the filter frame having the clamp structure further includes a plurality of shielding plates, each of which is installed on the long frame bar and the short frame bar, respectively, and covers the inner ring side position of each corner between the long frame bar and the short frame bar.

[0013] More specifically, the filter frame having the clamp structure includes, for each shielding plate, a first sheet and a second sheet, wherein the second sheet extends from the first sheet and is fixed to the long frame bar, and the first sheet is fixed to the short frame bar.

[0014] Furthermore, in the filter frame having the clamp structure, an inner bent portion is formed at one end of the first sheet of the shielding plate adjacent to the second sheet.

Each positioning plate abuts against both the top and bottom sides of the filter, thereby enhancing the widthwise stability of the filter on the long frame bar. This allows for a filter made of a relatively soft material, ensuring that each folded portion aligns in the same straight line, resulting in an orderly and stable arrangement. The through-holes allow the adhesive to flow when applied, reducing excessive flow resistance of the adhesive on the widthwise direction of the long frame bar. Shielding plates cover the four corners of the frame. The inner folded portion of the shielding plates prevents interference with components (e.g., rivets) used to secure the frame when assembling the filter. At the same time, the shielding plates increase the resistance of the adhesive to flow to the corners, reducing adhesive overflow at the corners. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0018] Referring to FIG. 1, a filter frame having a clamp structure of the present invention includes a frame structure 10, two clamp members 20, a plurality of position regulating plates 30, and a plurality of shielding plates 40.

[0019] Referring to FIGS. 1 and 2, the frame structure 10 includes two long frame bars 11 and two short frame bars 12. The two long frame bars 11 and the two short frame bars 12 are connected to each other to form a rectangular frame. The form of the frame structure 10 is not limited to the above. The frame structure 10 has opposite front side surfaces 13 and rear side surfaces 14. A plurality of side walls 15 are formed on the inner ring side surface of the frame structure 10. Each side wall 15 projects from the frame structure 10 and is adjacent to the front side surface 13 and the rear side surface 14 respectively. Therefore, the inner ring side surface of the frame structure 10 is grooved. A plurality of horizontal joints 16 are formed between the short frame bars 12 and the long frame bars 11 connected to each other. At both ends of each side wall 15 located on the long side of the long frame bar 11 in the present embodiment, a plurality of bending plates 151 are further extended. Specifically, the bending plate 151 is a sheet body bent and extended from the side wall 15 located on the long side of the long frame bar 11 toward the side wall 15 located on the short side of the long frame bar 11. The bending plate 151 overlaps with the side wall 15 located on the short side and is coupled and fixed by a rivet (not shown), but is not limited thereto, and the bending plate 151 may not be formed.

[0020] Referring to Figures 1 to 3, the clamp member 20 has a connecting sheet 21 and a clamp sheet 22. The connecting sheet 21 is a long sheet body having a U-shaped cross-section, and the clamp sheet 22 is a bent sheet body, one end of which is joined to the connecting sheet 21. Specifically, the connecting sheet 21 is fixed to one short frame bar 12 and is adjacent to the front surface 13 of the frame structure 10, the other end of the clamp sheet 22 extends toward the rear surface 14, and the clamp sheet 22 is bent toward the short frame bar 12. The clamp sheet 22 and the frame structure 10 maintain a certain distance from each other, but are not limited to this, the clamp sheet 22 does not have to be bent, and the form of the clamp member 20 may be changed according to the user's needs, such as being integrally molded. In other embodiments, the connecting sheet of the clamp member may be formed as a long sheet having an L-shaped cross-section, with one end connected to the clamp sheet and the other end fixed to a side wall 15 adjacent to the front surface 13 of the frame structure 10 of the short frame bar 12.

[0021] Referring to Figures 2 and 6, in other embodiments, the clamp member 20A may be formed as a folded sheet body having only a clamp sheet 22A, and a fixed sheet 17A is formed on the side wall 15A adjacent to the front side 13 of the frame structure 10 of the short frame bar 12A, bent toward the rear side 14, one end of the clamp sheet 22A is joined to the fixed sheet 17A, and the other end of the clamp sheet 22A is extended toward the rear side 14, and the clamp sheet 22A is bent toward the short frame bar 12A, but is not limited to this, and the clamp sheet 22A does not have to be bent, thereby further reducing the weight of the frame material and the amount of rivets used.

[0022] Referring to Figures 1 and 2, the position regulating plate 30 is a long body having an L-shaped cross-section, and the position regulating plate 30 has at least one through hole 31 passing through it, and the position regulating plate 30 is installed on the inner surface of the long frame bar 11, and the positions of the through holes 31 correspond to each side wall 15 located on the rear surface 14, and the position regulating plate 30 and the side walls 15 are separated by a certain distance, and in this embodiment the through holes 31 of the position regulating plate 30 are long holes and there are multiple such holes, extending along the length direction of the position regulating plate 30 and arranged at intervals, but it is not limited to this. The form of the position regulating plate 30 can be changed according to the user's requirements, such as the through holes 31 being long holes that extend to both ends.

[0023] The shielding plate 40 is a long sheet body that has been folded multiple times, and the shielding plate 40 includes a first sheet body 41 and a second sheet body 42, the second sheet body 42 is a sheet material that has been folded approximately 90 degrees or 270 degrees from the first sheet body 41, the inner folded portion 411 is located between the first sheet body 41 and the second sheet body 42, and the inner folded portion 411 is formed as a folded portion that protrudes toward the second sheet body 42 by the first sheet body 41, and in this embodiment, the number of shielding plates 40 is four. Each shielding plate 40 is fixed to one of the four corners of the frame structure 10, and the shielding plates 40 are used to connect adjacent long frame bars 11 and short frame bars 12. The clamp member 20 is assembled between the two shielding plates 40 located vertically, and after the shielding plates 40 are fixed, a gap is formed between the inner bent portion 411 of the first sheet body 41 and the short frame bar 12 and the long frame bar 11, but this is not limited to this, and the inner bent portion 411 may not be formed.

[0024] During assembly of the present invention, referring to Figures 1 to 5, the filter 50 is placed on the frame structure 10, positioned in the groove formed by the frame structure 10, and the clamp sheets 22 are inserted into the space between the two closest sheet bodies on either side of the filter 50 using the clamp members 20 on both sides. Since the clamp sheets 22 are elastic sheets, the sheet material closest to the filter 50 can be clamped and tightly attached to the short frame bar 12, thereby achieving the effect of quickly fixing both the left and right sides of the filter 50 and replacing the conventional method of bonding both sides of the filter 50 to the short frame bar 12 using adhesive. Each positioning plate 30 abuts against both the upper and lower sides of the filter 50, enhancing the stability of the filter 50 in the width direction of the long frame bar 11, and allowing each bent portion of the filter 50, which is made of a relatively soft main body material, to be positioned on the same straight line, resulting in an orderly and stable arrangement. Simultaneously with bonding, the through holes 31 allow the adhesive to flow, reducing excessive flow resistance of the adhesive in the width direction of the long frame bar 11.

[0025] In the above process, the transverse joint 16 at the intersection of the long frame bar 11 and the short frame bar 12 is located at the upper end of the side wall 15 of the long frame bar 11, maintaining a certain distance from the bottom of the groove of the long frame bar 11. As a bent plate 151 is formed on the long frame bar 11, it is possible to reduce the situation in which the adhesive flows to the corner and overflows from the joint.

[0026] In the above process, all four corner positions of the frame structure 10 are covered by the shielding plates 40, and the inner bent portion 411 of the shielding plates 40 can avoid interference with the components (such as rivets) that fix the frame structure when assembling the filter 50. At the same time, the shielding plates 40 can also increase the resistance of the adhesive flowing to the corner positions, reducing the overflow of adhesive at the corner positions.
