As shown in FIG. 3, the skeleton of the first frame 200 is formed by the first body 210. The first body 210 is formed in a rectangular tube shape penetrating the center thereof, and the space penetrated at the center thereof is the first coupling space 210a. One end of the connection frame 400 is coupled to the first coupling space 210a to be pressed in more detail. Although not shown, the inner groove of the first coupling space 210a is formed such that a seating groove in which the coupling protrusion 400 of the connection frame 400 is hooked. The coupling protrusion 400 is fixed to the seating groove so that the connection frame 400 is fixed to the first frame 200.

The first body 210 is formed to protrude a pair of the first fixing guide 220. The first fixing guide 220 is a portion in which a filter (not shown) for air purification is installed and fixed after the air filter frame assembly 100 is completely assembled.

The extension portion 340 is preferably formed of a length of 3mm ~ 42mm to be firmly coupled to the connection frame 400.

In addition, the widths J and K of the coupling spaces 210a and 310a in the first and second frames 200 and 300 are preferably formed to be between 1 mm and 28 mm. When the width of the coupling space (210a, 310a) is less than 1 mm, the coupling strength is weak, as the thickness of the connection frame 400 inserted into the coupling space (210a, 310a) is less than 1 mm, 28 mm or more In this case, the connection strength is excellent, but since the thickness of the first and second frames 200 and 300 must be thickened, the cost is increased, and the area of the filter used in the air filter frame assembly 100 is reduced, which reduces the performance. Because there is.

The thickness H of the first and second bodies 210 and 310 of the first and second frames 200 and 300 may be formed between 3 mm and 42 mm.

Preferably, the first and second fixing guides 220 and 320 are formed between 2 mm and 12 mm. When the first and second fixing guides 220 and 320 are 2 mm or less, the amount of the adhesive is not enough, so that the occurrence of leakage is high, the adhesive may leak to the outside, and thus the original purpose may not be met. This is because there is a disadvantage in that it acts as a structural resistance to the air flow.

As shown in FIG. 5, the connecting frame 400 is bent in the middle thereof so that its cross section is formed in a substantially '-' shape. The connecting frame 400 is formed in a shape corresponding to a cross section of the coupling spaces 210a and 310a so that its cross section is firmly fixed to the coupling spaces 210a and 310a.

It is formed so that the mounting groove is seated on the coupling protrusion 400, the connection frame 400 is firmly fixed to the first and second frames 200, 300, and as a result the first and second frames ( 200 and 300 are firmly fixed by the connection frame 400.

The length of the portion inserted into the first and second frames in the connecting frame is preferably formed of 20mm ~ 300mm. This is because the strength is lowered and the productivity is lower when 20mm or less, and when it is 300mm or more, the weight is difficult to handle and the unit price increases.

The coupling protrusion 400 is a conical shape in the present embodiment, but may be formed in various shapes such as a cone, a rectangular parallelepiped, a square pyramid, and an elliptical shape as necessary. Of course, in this case, the connection groove should be formed to fit the shape of the coupling protrusion 400.

The first and second frames 200 and 300 and the connection frame 400 may be fixed by an adhesive, if necessary, in this case, the connection frame 400 in the first and second frames 200 and 300. One end of this coupling may be formed to penetrate the through-hole Z so that the adhesive can reach the connection frame 400 when the adhesive is introduced.

In addition, the first and second frames 200 and 300 and the connecting frame 400 are manufactured by extrusion and injection, and the material is appropriately selected from among aluminum, ABS, PP, PET, PBT, and PES according to the specification. Can be used.

More specifically, the coupling space 210a of the first frame 200 is coupled to the connection frame 400 by interference fit, or fixed using an adhesive if necessary. At this time, the connecting frame 400 is formed so that the coupling protrusion 400 is projected to be coupled to fit well in the connecting groove of the first frame 200. As shown in FIG. 6, the first frame 200 prepares a pair and couples the connection frame 400 to each other.

The second frame 300 is coupled to the other end of the connection frame 400 in a state in which the connection frame 400 is all coupled to the first frame 200. In this case, the combining process is the same as the combining process of the first frame 200.

When the second frame 300 is coupled to the connection frame 400, one end of the second frame 300 is coupled to the stepped portion 230 of the first frame 200.

In this case, an additional process (welding, screwing, etc.) for fixing the first and second frames 200 and 300 to the connection frame 400 is unnecessary, thereby assembling the air filter frame assembly 100. This becomes very simple. In addition, the first and second frames 200 and 300 and the connection frame 400 may be fastened by pressure or adhesion rather than by a separate tool, so that the first and second frames 200 and 300 may be fastened. And wider selection of materials for manufacturing the connecting frame 400. In other words, when the strength is not largely required, the frame can be produced through simple manufacturing by extrusion, so that the selection of materials is wider and the range of application thereof becomes wider.

In addition, the first and second frames 200 and 300 are more firmly fixed by the stepped portion 230, so that the strength of the air filter frame assembly 100 is improved.
