DETAILED DESCRIPTION Example 1

[0024] See also Figure 1-3 The utility model relates to a quick shaping connection structure of a corrugated board, comprising a corrugated board 1, wherein the corrugated board 1 is alternately provided with crest sections 1.1 and trough sections 1.2 along the length direction, wherein a U-shaped keel 2 is clamped at the end of the corrugated board 1, and a clamping protrusion 2.1 is provided on one side of the inner wall of the U-shaped keel 2 along the length direction, and each crest section 1.1 of the corrugated board 1 is provided with a slot 1.1.1 corresponding to the clamping protrusion 2.1, ensuring that the clamping protrusion 2.1 matches each slot 1.1.1, and the inner wall of the U-shaped keel 2 on the side of the clamping protrusion fits with the crest section 1.1, and the inner wall of the U-shaped keel 2 away from the side of the clamping protrusion fits with the trough section 1.2.

[0025] The cross-section of the snap-fitting protrusion 2.1 is a right-angled triangle, which improves the strength of the snap-fitting protrusion, and includes a guiding bevel 2.1.1 and a horizontal right-angled side 2.1.2. The guiding bevel 2.1.1 is close to the slot of the U-shaped keel 2. When the corrugated board 1 is installed, the corrugated board 1 first contacts the guiding bevel 2.1.1 to guide the corrugated board 1 to be inserted into the bottom of the slot of the U-shaped keel 2. After snap-fitting, the horizontal right-angled side 2.1.2 contacts the slot hole 1.1.1, and the snap-fitting protrusion 2.1 will not be deformed after being subjected to force.

[0026] The bottom of the U-shaped keel 2 is provided with drainage holes 2.2, and the drainage holes 2.2 are arranged at two corners of the bottom of the groove to prevent water accumulation.

[0027] Adjacent U-shaped keels 2 are spliced ​​together by connecting pieces, so the ends of the U-shaped keels 2 in the length direction are provided with connecting holes to facilitate the clamping of the connecting pieces.

[0028] The U-shaped keel 2 is an integrally formed plastic part or aluminum alloy part, wherein the plastic part is integrally injection molded and the aluminum alloy part is integrally extruded. The clamping protrusion will not be deformed after the whole is subjected to force, thereby ensuring a more stable connection between the U-shaped keel and the corrugated board. Example 2

[0029] See also Figure 4-6The U-shaped keel 2 is formed by integral bending, including a U-shaped base section 2.3, one end of the U-shaped base section 2.3 is bent inward to form a first vertical extension side 2.4, and the other end is bent inward to form a second vertical extension side 2.5, a guide bevel side 2.1.1, a horizontal right-angle side 2.1.2 and a third vertical extension side 2.6 in sequence, wherein the guide bevel side 2.1.1 and the horizontal right-angle side 2.1.2 form a snap-on protrusion 2.1.

[0030] The first vertical extension side 2.4 is in contact with the inner wall of one side of the U-shaped base section 2.3, and the second vertical extension side 2.5 and the third vertical extension side 2.6 are in contact with the inner wall of the other side of the U-shaped base section 2.3 at the same time. The snap-fit ​​protrusion 2.1 is formed into a stable triangular structure by bending, thereby improving the strength of the snap-fit ​​protrusion. The snap-fit ​​protrusion 2.1 is protected by the second vertical extension side 2.5 and the third vertical extension side 2.6 and will not be deformed during the force application process.

[0031] The rest of the structure is the same as that of Example 1.

[0032] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
