(15) In order to further understand the goal, characteristics and effect of the present invention, a number of embodiments along with the drawings are illustrated as following:

(16) Referring to FIGS. 1 to 4, the present invention provides a shelving structure which comprises at least four vertical posts (10), at least four annular spacers (20), and at least a shelf board (30). Wherein the posts (10) are configured to be mounted on the shelf board (30) through the annular spacers (20). The shelf board (30) has a frame (31) and a panel (32), and a convex portion (311) is formed at an inner edge of the frame (31). At least eight horizontal supporting boards (312) which are respectively tilted with a preferable angle are formed at four upper edges and four lower edges of the frame (31) respectively, and each two opposed supporting boards are parallel with each other. Moreover, each of the supporting boards (312) has an inner edge which is bent to form a hook-like lip portion (313). Each two adjacent supporting boards (312) are not connected to each other, and each of four corners of the frame (31) is bent to form a concave groove (314). Moreover, four arc boards (33) are respectively assembled with the four concave grooves (314), and each of the arc boards (33) has two wings (331) extending from two lateral sides thereof, and an abutting portion (332) is horizontally bent and formed at an upper end of the arc board (33). Wherein a position of the abutting portion (332) is higher than the wings (331) such that the wings (331) are configured to be welded with the frame (31) and each of the abutting portions (332) is configured to abut against the supporting boards (312), which are located at the upper edge of the frame (31), at two sides thereof, thereby forming a connecting tube (34) between the arc board (33) and the concave groove (314) to couple with and secure the annular spacer (20). In addition, the panel (32) received in the frame (31) through an outer edge thereof is secured with the supporting boards (312) at the upper edge of the frame (31). Also, at least a reinforcing bar (35) is formed inside the panel (32), and two ends of the reinforcing bar (35) are respectively secured on two parallel edges of the frame (31). Wherein each of the two ends of the reinforcing bar (35) has a recess portion (351), and the two recess portions (351) are configured to respectively engage with the convex portion (311) at the two parallel edges of the frame (31). Moreover, each of the two ends of the reinforcing bar (35) comprises two engaging notches (352) respectively formed at an upper edge and a lower edge thereof.

(17) Structurally, referring to FIGS. 3 and 4, the four arc boards (33) are respectively secured with the four concave grooves (314) located at the four corners of the frame (31) of the shelf board (30), and each of the arc boards (33) is inserted into the frame (31) through the two wings (331) thereof. Furthermore, the two wings (331) are configured to be welded on the convex portion (311) of the frame (31), and concurrently the abutting portion (332) of the arc board (33) is configured to upwardly abut against the two supporting boards (312) located at two sides of the concave groove (314), thus securing the arc board (33) on the corner of the frame (31). Additionally, each of the four connecting tubes (34) is formed between the arc board (33) and the concave groove (314). In one embodiment, the panel (32) is a general enclosed panel or a mesh panel. The panel (32) is positioned on an upper portion of the frame (31), and four edges of the panel (32) are respectively secured by the four supporting boards (312). Also, the shelf board (30) has at least one reinforcing bar (35), and the two ends thereof are respectively received in two parallel edges of the frame (31). Moreover, the two ends of the reinforcing bar (35) comprises the recess portions (351) which are configured to engage with the convex portion at the two parallel edges of the frame (31) such that the reinforcing bar (35) is configured to support a bottom of the panel (32), thereby enhancing the loading capability of the panel (32).

(18) In actual application, referring to FIGS. 1, 2, and 5 to 7, the four posts (10) are mounted on the shelf board (30) at four corners thereof, and each of the four annular spacers (20) disposed on an upper portion of the post (10) is configured to receive in the connecting tube (34) of the shelf board (30). Wherein each of the four annular spaces (20) is configured to concurrently abut against the arc board (33) and the convex portion (311) of the frame (31) located at two sides of the arc board (33), thus firmly securing the annular spacer (20) with the connecting tube (34). In addition, the posts (10) are formed in bamboo shape, and each of the annular spacers (20) has at least a horizontal engaging rib (21) protruding from an inner surface thereof. Thus, each of the annular spacers (20) is configured to be abutted by the connecting tube (34) to firmly dispose on the post (10).

(19) Comparing with conventional shelves, the present invention is advantageous because: (i) the shelf board (30) has the four concave grooves (314) formed at the four corners thereof, and each of the concave grooves (314) is engaged with the arc board (33) which is configured to reduce the manufacturing cost; (ii) each of the arc boards (33) has the two wings (331) which are configured to be welded with the convex portion (311) of the frame (31), thus improving the structural strength and life time of the shelf; (iii) when each of the annular spacers (20) is received in the connecting tube (35), the convex portion (311) of the frame (31) is configured to abut against the annular spacer (20) such that the annular spacer (20) is configured to abut against the connecting tube (34) of the shelf board (30) with a large contact area, thus improving the structural strength between the annular spacer (20) and the post (10); and (iv) each of the supporting boards (312) has one bend lip portion (313), which is configured to prevent a user from cuts by the supporting boards (312) during installation or moving process thereby improving the safety of use.

(20) Having described the invention by the description and illustrations above, it should be understood that these are exemplary of the invention and are not to be considered as limiting. Accordingly, the invention is not to be considered as limited by the foregoing description, but includes any equivalents.
