The first plate 112 and the third plate 114 are parallel to each other. The second plate 116 and the fourth plate 118 are parallel to each other. The first plate 112 is connected to the second plate 116, the second plate 116 is connected to the third plate 114, the third plate 114 is connected to the fourth plate 118, the fourth plate 118 is connected back to the first plate 112, and thus these four plates can be integrated together so as to form a square tube having a hollow space PA. The trapezoidal hole G is provided to one of these four plates; for example, the first plate 112 in this embodiment. However, for a concise explanation in the following description, in this embodiment, the trapezoidal hole G is furnished at the first plate 112, and the first trapezoidal hole G1 and the second trapezoidal hole G2 are integrated as a hole set of the trapezoidal hole G, any two neighboring trapezoidal holes G are separated by the same distance, and the trapezoidal holes G are orderly arranged in a vertical manner.

Namely, in the upright assembly direction LC2, the first trapezoidal hole G1 is shaped as a trapezoid having a wider upper end. Similarly, the second trapezoidal hole G2 would be shaped the same as the first trapezoidal hole G1. In addition, the top side GA of the first trapezoidal hole G1 is spaced from the top side GA of the second trapezoidal hole G2 by a first distance D1, the top side GA of the first trapezoidal hole G1 is spaced from another top side GA of the next first trapezoidal hole G1 by a second distance D2, and the distance between the second trapezoidal hole G2 and the upper first trapezoidal hole G1 is less than that between the second trapezoidal hole G2 and the lower first trapezoidal hole G2.

The first bent plate M1 and the second bent plate M2 are individually bent into the first trapezoidal hole G1 (and the second trapezoidal hole G2), and the first bent plate M1 and the second bent plate M2 are individually bent and extended into an inner surface of the first plate 112 from a first side GC and a second side GD of the first trapezoidal hole G1, respectively, such that the first bent plate M1 and the second bent plate M2 can be both located in the hollow space PA. For example, either of the first bent plate M1 and the second bent plate M2 can be an internal plate bent from an exterior surface of the first plate 112, and each of the first bent plate M1 and the second bent plate M2 has a protrusive length K3.

The first bent plate M1 and the second bent plate M2 are both obliquely disposed to match the wide-top trapezoidal hole G. For example, the first bent plate M1 and the second bent plate M2 are oppositely disposed, and a top end of the first bent plate M1 (close to the top side GA of the first trapezoidal hole G1) and a corresponding top end of the second bent plate M2 (close to the top side GA of the first trapezoidal hole G1) are separated by a distance K1 greater than a distance K2 between a bottom end of the first bent plate M1 (close to the bottom side GB of the first trapezoidal hole G1) and a corresponding bottom end of the second bent plate M2 (close to the bottom side GB of the first trapezoidal hole G1). Obviously, both the first bent plate M1 and the second bent plate M2 are individually slope pieces.

The connecting components 120 are disposed to opposite sides of the second transverse member 136, such that these four connecting components 120 can be fallen into four corners of the storage layer 130.

The connecting component 120 includes a fixing piece 122, a bent connecting piece 124, a first hook piece N1, a second hook piece N2 and a resisting piece 126. The fixing piece 122 fixed to one of the opposite ends of the second transverse member 136 is to assemble the connecting component 120 to the storage layer 130. A side of the bent connecting piece 124 is connected with the fixing piece 122, while another end thereof is connected to the first hook piece N1 and the second hook piece N2 so as to form a U-shape part.

In addition, the first hook piece N1 and the second hook piece N2 are individually not parallel to the fixing piece 122, such that each of the first hook piece N1 and second hook piece N2 can form an inclined angle A1 with respect to the fixing piece 122. In some other embodiments, only one hook piece is included.

In the following description, FIG. 9 to FIG. 17 are utilized to elucidate the assembly process of this disclosure. In order to explain concisely, FIG. 9 to FIG. 16 do not show the storage layers of FIG. 1. Firstly, as shown in FIG. 9 and FIG. 10, the connecting component 120 is moved toward along an assembly direction LC1. The assembly direction LC1 is guided to the first trapezoidal hole G1 and the second trapezoidal hole G2 of the first plate 112 of the post component 110, with the first hook piece N1 to face the first trapezoidal hole G1, and the second hook piece N2 to face the second trapezoidal hole G2. Then, in FIG. 11 and FIG. 12, the first hook piece N1 is inserted into the first trapezoidal hole G1, and the second hook piece N2 is inserted into the second trapezoidal hole G2. The resisting piece 126 disposed on an outer surface of the first plate 112 of the post component 110, and the fixing piece 122 is to contact an outer surface of the second plate 116 of the post component 110.

Then, in FIG. 13 and FIG. 14, the connecting component 120 is depressed down along the upright assembly direction LC2 (i.e., a downward application) so as to have the first hook piece N1 to buckle the first trapezoidal hole G1 and the second hook piece N2 to buckle the second trapezoidal hole G2, respectively. In the downward assembling of the connecting component 120 along the upright assembly direction LC2, since both the first trapezoidal hole G1 and the second trapezoidal hole G2 are wide-top trapezoidal hole designs, thus the first hook piece N1 and the second hook piece N2 would be designed accordingly. As shown in FIG. 15 and FIG. 16, along with the first hook piece N1 and the second hook piece N2 to move in the upright assembly direction LC2, the first hook piece N1 and the second hook piece would be tightly fitted by the first trapezoidal hole G1 and the second trapezoidal hole G2, respectively. Thereupon, the assembly is obviously convenient. Also, through the structuring match, the connecting component 120 can be firmly assembled to the post component 110, as shown in FIG. 17. Namely, the storage layer 130 can be assembled to the post component 110.

As shown, the first hook piece N1 and the second hook piece N2 are respectively contacted at the first bent plate M1, and the extension piece N11 and the extension piece N21 of the second hook piece N2 are respectively disposed inner the first plate 112. In addition, as shown in FIG. 16, the first trapezoidal hole G1 and the second trapezoidal hole G2 still have rooms for another connecting component 120 to engage, as shown in FIG. 18, for horizontal extension or further assembly of the screw-less and no rivet combined type shelf 100 of FIG. 1 along the horizontal direction L1, and thus the assembly convenience can be substantially enhanced.

Referring to FIG. 19 and FIG. 20, where FIG. 19 is a rear side view of FIG. 1. The post components 110 along the stacking direction L2 can be divided into the first post components 110A and the second post components 110B, and the second post components 110B is located above the first post components 110A. In one embodiment, a connector 140 can be used to connect linearly the first post component 110A and the second post component 110B in the stacking direction L2, so as to reach a desired height of the screw-less and no rivet combined type shelf 100. For example, the connector 140 includes a first protruded end 142 and second protruded end 144. The first protruded end 142 is to be plugged into the first post component 110A, and the second protruded end 144 is to be plugged into the second post component 110B. The first protruded end 142 has an empty space F1 for exposing the first trapezoidal hole G1, and the second protruded end 144 has another empty space F2 for exposing the second trapezoidal hole G2.
