Description

[Technical Field]

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

[0002] As shown in Taiwan Patent Application Publication No. 202511677, filters in the prior art, especially corrugated folding filters, are usually fixed to a frame, which is then fixed to the mounting seat of the filter device. The frame is a rectangular frame consisting of two long frame bars and two short frame bars, and the inner ring side of the frame is grooved. The method of assembling the filter and the frame is to place the filter on the frame and then apply adhesive between the filter and the frame to bond them together.

[0003] However, when a filter is placed inside a frame, the gap between the filter and the frame becomes very small, making the bonding process difficult. For example, to smoothly apply the adhesive, the adhesive nozzle must be inserted into the gap between the filter and the frame. However, during the insertion process, the filter and the frame are compressed, which can easily cause damage, deformation, or even overflow of the adhesive. Therefore, it is necessary to address the above problems and shortcomings. [Prior art documents] [Patent documents]

[Means for solving the problem]

[0006] In order to achieve the above object of the invention, the technical means adopted by the present invention is to design a filter frame with a clamping structure used for fixing a filter, and the filter frame with the clamping structure comprises: a frame structure having opposing front and rear sides; Two clamp members respectively installed on the inner ring side surfaces on both the left and right sides of the frame structure; Including, a plurality of side walls are formed on an inner annular side surface of the frame structure, each of the side walls protruding from the frame structure and adjacent to the front side surface and the rear side surface, The two clamping members are used to clamp the filter disposed within the frame structure.

[0007] Further, in the filter frame having the clamp structure, each of the clamp members has a connecting sheet and a clamp sheet, one end of the clamp sheet is connected 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 are interconnected to form a rectangular frame, the connecting sheet of each clamp member is fixed to one of the short frame bars and is adjacent to the front side of the frame structure, and the other end of the clamp sheet extends toward the rear side.

[0009] More specifically, the filter frame having the clamp structure includes a frame structure that includes two long frame bars and two short frame bars, the two long frame bars and the two short frame bars being interconnected to form a rectangular frame, each of the short frame bars having a fixing seat that is located on a side wall adjacent to the front side of the frame structure and extends toward the rear side, and each of the clamp members has a clamp seat, one end of the clamp seat of each of the clamp members being fixed to one of the fixing seats, and the other end of the clamp seat extending toward the rear side.

[0010] More specifically, the filter frame having the clamping structure further includes a plurality of position control plates, each of which has at least one through hole, and 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] More specifically, in the filter frame having the clamp structure, the through holes of each of the position control plates are elongated holes, there are multiple holes, and they extend along the length of each of the position control plates and are arranged at intervals.

[0012] In further detail, the filter frame with the clamping structure further includes a plurality of shielding plates, each of which is installed on the long frame bar and the short frame bar, and covers the inner ring side positions of each corner between the long frame bar and the short frame bar.

[0013] Further, in the filter frame having the clamp structure, each of the shielding plates includes a first sheet and a second sheet, the second sheet extending from the first sheet and fixed to the long frame bar, and the first sheet fixed to the short frame bar.

[0016] The advantages of this invention include the ability to quickly secure both sides of the filter by clamping the filter between the two clamping members and tightly fitting it to the short frame bar, replacing the traditional adhesive-based technique, which requires time for production and assembly, and overcomes the drawbacks of adhesive overflow. The positioning plates abut the top and bottom of the filter, enhancing the stability of the filter's long frame bar across the width. The filter's body is made of a relatively soft material, and the folded sections are aligned in a straight line, ensuring a neat and stable layout. The through-holes allow the adhesive to flow freely when the adhesive is applied, reducing excessive flow resistance across the long frame bar. The four corners of the frame are covered by shielding plates, whose inward bends prevent interference with components (e.g., rivets) used to secure the frame during filter assembly. The shielding plates also increase the adhesive's resistance to flow into the corners, reducing overflow at the corners. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

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

[0019] Referring to Figures 1 and 2, the frame structure 10 includes two long frame bars 11 and two short frame bars 12, and 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 a front side 13 and a rear side 14 facing each other. The inner ring side of the frame structure 10 is formed with a plurality of side walls 15, each of which protrudes from the frame structure 10 and is respectively connected to the front side 13 and the rear side 14. The short frame bars 12 and the long frame bars 11 are adjacent to each other, so that the inner ring side surface of the frame structure 10 is groove-shaped, and a plurality of horizontal joints 16 are formed between the connected short frame bars 12 and the long frame bars 11. In this embodiment, a plurality of folded plates 151 are further extended from both ends of each side wall 15 located on the long side of the long frame bar 11. Specifically, the folded plates 151 are sheets that are folded and extended from the side wall 15 located on the long side of the long frame bar 11 to the side wall 15 located on the short side of the long frame bar 11. The folded plates 151 overlap the side wall 15 located on the short side and are connected and fixed with rivets (not shown), but the present invention is not limited to this, and the folded plates 151 may not be formed.

[0020] 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 connected to the connecting sheet 21. Specifically, the connecting sheet 21 is fixed to one of the short frame bars 12 and is adjacent to the front side surface 13 of the frame structure 10, and the other end of the clamp sheet 22 extends toward the rear side 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, but this is not limited thereto. The clamp sheet 22 may not be bent, and the type of the clamp member 20 may be changed according to the user's needs, such as being integrally molded. In another embodiment, the connecting sheet of the clamping member may be formed as a long sheet body having an L-shaped cross section, one end of which is connected to the clamping sheet and the other end of which is fixed to the side wall 15 of the short frame bar 12 adjacent to the front side 13 of the frame structure 10.

[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 bent toward the rear side 14 is formed on the side wall 15A adjacent to the front side 13 of the frame structure 10 of the short frame bar 12A, one end of the clamp sheet 22A is connected to the fixed sheet 17A, and the other end of the clamp sheet 22A extends 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 may not be bent, which can further reduce the weight of the frame material and the amount of rivets used.

[0022] 1 and 2, the positioning plate 30 is an elongated body with an L-shaped cross section, and has at least one through-hole 31. The positioning plate 30 is installed on the inner surface of the elongated frame bar 11, and the through-holes 31 are positioned corresponding to the side walls 15 located on the rear surface 14, and the positioning plate 30 and the side walls 15 are spaced apart by a certain distance. In this embodiment, the through-holes 31 of the positioning plate 30 are elongated holes, and there are multiple through-holes 31 that extend along the length of the positioning plate 30 and are spaced apart, but this is not limited to this. The shape of the positioning plate 30 can be changed according to user requirements, such as elongated holes 31 extending to both ends.

[0023] The shielding plate 40 is a long sheet that is folded multiple times. The shielding plate 40 includes a first sheet 41 and a second sheet 42. The second sheet 42 is a sheet material that is folded approximately 90 degrees or 270 degrees from the first sheet 41. The inner folded portion 411 is located between the first sheet 41 and the second sheet 42. The inner folded portion 411 is formed as a folded portion that protrudes from the first sheet 41 toward the second sheet 42. In this embodiment, the number of shielding plates 40 is four. Each shielding plate 40 is fixed at the four corners of the frame structure 10, and the shielding plates 40 are used to connect the adjacent long frame bars 11 and short frame bars 12. The clamping member 20 is assembled between the two shielding plates 40 located above and below. After the shielding plates 40 are fixed, a space is formed between the inner bending portion 411 of the first sheet body 41 and the short frame bars 12 and long frame bars 11, but this is not limited to this, and the inner bending portion 411 may not be formed.

[0024] 1-5, when assembling the present invention, the filter 50 is placed on the frame structure 10, positioned in the groove formed by the frame structure 10, and the clamping sheets 22 are inserted into the spaces between the two closest sheets on both sides of the filter 50 using the clamping members 20 on both sides. Because the clamping sheets 22 are elastic, the sheet material closest to the filter 50 can be clamped and tightly attached to the short frame bar 12, thereby quickly securing both sides of the filter 50 and replacing the prior art method of using adhesive to bond both sides of the filter 50 to the short frame bar 12. The positioning plates 30 abut the top and bottom of the filter 50, enhancing the stability of the filter 50 across the width of the long frame bar 11 and aligning each bent portion of the filter 50, which is made of a relatively soft material, on the same straight line, ensuring a neat and stable arrangement. During bonding, the through-holes 31 allow the adhesive to flow through, reducing excessive flow resistance of the adhesive across the width of the long frame bar 11.

[0025] In the above process, the horizontal 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, and maintains a certain distance from the bottom of the groove of the long frame bar 11. A folded plate 151 is formed on the long frame bar 11, which can reduce the situation where the adhesive flows into the corners and spills out from the joint.

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