Description

Front and back structure of shelf

The present invention relates to a rack, especially a front and back structure of a rack that can be assembled on both sides.

Press, the improved structure of the conventional rack is shown in Figure 9 and Figure 10, which includes: at least four pillars (40) and at least one set with a plurality of ring gaskets (50) on the layer of the four pillars (40) Plate (60), wherein the column (40) has a number of positioning ring grooves (41), and the ring gasket (50) is a tapered ring gasket (50) with a narrow top and a wide bottom. The horizontal fastening rib (51), the layer board (60) is formed by combining a frame body (61) and a storage board (62), the inner surface of the frame body (61) is provided with a fitting convex surface (611), and the upper and lower end edges of the four sides of the frame (61) are all bent with parallel horizontal ribs (612), and a protective lip is set inwardly at the ends of the two horizontal ribs (612) (613), and the two sides of the horizontal ribs (612) are not connected, and are respectively bent at each corner of the frame body (61) to form an inner concave arc groove (614), the inner concave arc grooves (614) A combined arc plate (615) is respectively arranged. Both sides of the combined arc plates (615) are provided with a fin (6151) extending outward, and the upper end of the combined arc plate (615) has a horizontally bent abutment The ribs (6152), and the abutting ribs (6152) are higher than the fins (6151) on both sides, and then the fins (6151) are fixed to the frame (61) so as to pass through the combined arc plate (615) and inner The concave arc grooves (614) are wound to form a hollow cone-shaped sleeve part (63) with an upper narrow and a lower width. The storage plate (62) is accommodated in the frame (61) and fixed to The horizontal ribs (612) on the upper edge of the frame body (61), the part of the frame body (61) that is not connected to the fixed object plate (62) forms a guardrail (616), and the casing part (63) is used on the Narrow and wide hollow cone-shaped inner wall, making Both the ring gasket (50) and the sleeve part (63) of the laminate (60) form a tight state between the surface and the surface, which greatly improves the tightening strength between the ring gasket (50) and the column (40) .

However, in actual use, the improved structure of the rack as described above still has the following shortcomings: the inner concave arc groove (614) and the sleeve part (63) formed by the combined arc plate (615) are the same The upper narrow and lower wide hollow conical sleeve part (63) is assembled with the inner wall of the sleeve part (63) nested in the conical ring gasket (50) to make the ring gasket ( 50) The column (40) is pressed tightly to form a fixation, so the layer board (60) cannot be turned over and assembled at will, so that the user cannot choose whether to have a guardrail (616) on the surface during use.

Therefore, how to develop and improve the shortcomings of the improved structure of the rack described above is actually the goal of the relevant industry’s efforts to develop. In view of this, the inventor has thought and invented the idea, and has spent many years Designed by experience, discussed in many ways and tested on samples, and revised and improved many times, the present invention is introduced.

In the improved structure of the above-mentioned shelf, since the sleeve part of the laminate is a tapered sleeve part with a narrow top and a wide bottom, it can only be nested in the ring-shaped gasket in a single direction, so that the laminate cannot be freely inserted. Flip assembly, this is the technical problem to be solved.

The present invention provides a front and back structure of a rack, which comprises: at least four uprights and at least one layer plate with a plurality of annular gasket sets on the four uprights, wherein: the upright has a number of positioning ring grooves, The ring-shaped gasket is a tapered ring-shaped gasket with a narrow top and a wide bottom. Its inner periphery has a transverse buckling rib. The layer board is formed by combining a frame and a storage board. The inner surface of the frame body is provided with a fitting convex surface, and the upper and lower end edges of the four sides of the frame body are bent with parallel horizontal ribs, and the end of the horizontal ribs at the upper end is curved inwardly with a protection The lip, and the two sides of the horizontal ribs are not connected, and are respectively bent at each corner of the frame to form an inner concave arc groove, the groove wall of the inner concave arc groove goes up and down at a symmetrical angle from the middle section The outer sides of the two ends are inclined, and the inner concave arc groove is respectively equipped with a combined arc plate whose wall is inclined from the middle section to the outer side of the upper and lower ends, and both ends of the combined arc plate are extended outwardly with a fin, and The upper end of the combined arc plate has an abutting rib that is horizontally bent outward, and the abutting rib is higher than the fins on both sides, and then the combined arc is connected to the frame through the fins, and the The two outer ends of the abutting ribs abut against the horizontal ribs on both sides of the inner concave arc groove, so as to form an hourglass-shaped hollow with two outer ends wide and middle section narrow through the circle between the combined arc plate and the inner concave arc groove The sleeve part is used for the locking and fixing of the annular gasket, the storage plate is accommodated in the frame body and connected to the horizontal ribs on the upper edge of the frame body, and the frame body has no connection The part of the fixed object plate forms a guardrail. Through the characteristics of the wide and narrow middle section at the two outer ends of the sleeve part, the layer plate can be reversed and assembled on both sides, which greatly increases the convenience of use, so as to obtain a kind of shelf front and back. Structurer.

The present invention provides a front and back structure of a shelf, because the inner concave arc groove of the frame body and the groove wall and the plate wall of the combined arc plate are inclined from the middle section to the outer side of the upper and lower ends, through the combined arc plate and the inner concave arc groove The middle ring is wound to form one or two hourglass-shaped hollow sleeves with a wide outer end and a narrow middle section, so that the laminate can be flipped and assembled on both sides, so that the user can choose whether to have a frame guardrail when assembling. It greatly increases the convenience of use.
