1 and 2 show a preferred embodiment of the composite frame strip 1 of the present invention, which includes a long core material 11 and a long hollow frame 12 for accommodating the long core material 11. The elongated core material 11 is inserted into the elongated hollow frame 12 after applying glue on its surface, so that the elongated core material 11 is bonded and fixed in the elongated hollow frame 12 by the glue.

The long core material 11 can be made of solid wood board, wood core board, plywood, dense board, plastic plywood, or other wooden boards. The long hollow frame 12 can be made of plastic or metal. For example, an aluminum extrusion method is selected to make the long hollow frame 12, or a plastic steel is selected to make the long hollow frame 12. In addition, the surface of the long hollow frame 12 can be coated or electroplated with a desired color as required, for example, a layer of black baking varnish or electroplating to form a bright metal layer.

Preferably, one or more combined holes 113 can be made on the long core material 11 as required, but this is not necessary. The long hollow frame 12 needs to make a perforation 123 at the position corresponding to the combined holes 113. Each combination hole 113 and the corresponding through hole 123 can be used to install a KD coupler or other connecting components.

Figures 4 and 5 show a situation where two composite frame strips 1 are assembled with each other using two KD couplers. Each KD coupling includes a KD bolt 13 and a KD rotating block 14. The two KD rotating blocks 14 respectively pass through the two perforations 123 of the long hollow frame 12 of one of the composite frame strips 1 and then are inserted into the two combined holes 113 of the long core material 11. The two KD bolts 13 respectively pass through the two through holes 123 of the long hollow frame 12 of the other composite frame strip 1 and then are screwed into the two combined holes 113 of the long core material 11. In this way, the two composite frame strips 1 can be quickly assembled together by the KD coupler. In any case, multiple composite frame strips 1 and multiple KD couplers can form a frame (not shown in the figure).

The long hollow frame 12 made of metal or plastic not only protects the wooden long core material 11 inside it, reduces the chance of the wooden long core material 11 from being damp, but also improves the overall structural strength and is not easy to bend, which solves the traditional wooden system cabinet The wooden connecting column is prone to damp and easy to bend. In addition, the metal long hollow frame 12 provides the texture of industrial style, so the composite frame strip 1 is applied to the wooden system cabinet to form an industrial air system cabinet. Since the assembly of the composite frame strip 1 also uses the KD coupler commonly used in wooden cabinets, there is no need to use special connecting components like the assembly of traditional metal pipe columns, so the complexity of the assembly can be reduced, and the assembly speed can be accelerated. Solve the problems of high complexity and slow combination speed of cabinets in the industrial air system in the past.

In this embodiment, as shown in FIG. 3, the outer wall surface of the elongated hollow frame 12 has a plurality of grooves 122 that are parallel to each other and extend along the length of the elongated hollow frame 12, and the inner wall surface of the elongated hollow frame 12 has multiple There are protruding strips 121 parallel to each other and extending along the length of the long hollow frame 12, and each groove 122 faces away from each protruding strip 121 respectively. As shown in FIG. 2, the thickness of each convex strip 121 of the long hollow frame 12 is thicker than other parts of the long hollow frame 12, so each convex strip 121 has enough thickness to make the groove 122 on its back. . In addition, the cross-sectional shape of each groove 122 is preferably V-shaped.

As shown in Figure 1, the center of the perforation 123 on the long hollow frame 12 falls in the groove 122. This is because when a construction worker drills the perforation 123 with a drilling tool, the drilling tool is used first. The tip of the drill bit enters the groove 122 and then drills, so the center of the perforation 123 will fall on the groove 122. Since the groove 122 can provide the tip of the drill bit to abut against, so that the drill bit can drill smoothly, avoiding the situation that the drill bit will slide at will when it starts to rotate. That is to say, if there is no groove 122, the tip of the drill bit There is no place to lean against. If the hand does not hold the drilling tool firmly, the drill bit will slide arbitrarily as soon as it rotates, which will damage the surface of the long hollow frame 12 and even drill the worker.

As shown in FIGS. 1 and 2, the two sides of each groove 122 of the elongated hollow frame 12 have the same or substantially the same width W. Therefore, when the two composite frame strips 1 are assembled to each other, the groove 122 can be used for alignment. The groove 122 is aligned with the groove 122 on the left side of the wide side of the long hollow frame 12 of the other composite frame strip 1, as shown in FIG. 7 and 8 shows that the groove 122 on the short side of the long hollow frame 12 of one of the composite frame strips 1 is aligned with the groove 122 in the middle of the wide side of the long hollow frame 12 of the other composite frame strip 1. 9 and 10 show that the groove 122 on the short side of the long hollow frame 12 of one of the composite frame strips 1 is aligned with the wide side of the long hollow frame 12 of the other composite frame strip 1 to the right的槽122。 The groove 122. Through the aforementioned alignment operation, one of the composite frame strips 1 can accurately abut the left, middle, or right positions of the wide side of the other composite frame strip 1, regardless of the one of the composite frame strips. The strip 1 is against the left or right side of the wide side of the other frame strip 1, and one of the composite frame strips 1 is aligned with or does not exceed the edge of the other composite frame strip 1. There will be outstanding situations.

In the above embodiment, the composite frame strip 1 is rectangular, but not limited to this. For example, as shown in FIGS. 11 and 12, the composite frame strip 1 is square. It should be pointed out that composite frame strips 1 of different shapes can also be assembled to each other using KD couplers. For example, as shown in Figures 12 and 14, a square composite frame strip 1 is assembled to a rectangular composite frame strip 1 .

In addition, as shown in FIG. 2 again, each convex strip 121 of the elongated hollow frame 12 is spaced apart from each other by a certain distance and each abuts against the elongated core material 11, so that there is a gap between the elongated hollow frame 12 and the elongated core material 11 A plurality of gaps 10 are formed, and the gaps 10 can accommodate a large amount of glue, so that the long core material 11 and the long hollow frame 12 are firmly combined.

As shown in Figures 15 and 16, multiple composite frame strips 1, multiple KD couplers (not shown in the figure) and multiple wooden cabinets 15 or multiple wooden boards 16 can be combined to form a storage cabinet or A cabinet, but its shape is not limited to what is shown in the figure.
