Shelf structure (I)

Abstract

A shelf structure (a) includes: a plurality of frame rods, a plurality of fasteners, and a plurality of shelf panels. The frame rods have two perpendicular facades, each of which has a plurality of snap-fit ​​parts arranged sequentially from top to bottom. The snap-fit ​​parts provide fasteners for assembly from the outside, allowing the fasteners to be freely installed on the snap-fit ​​parts at any height on the frame rods. The shelf panels are provided on the inside for snap-fitting with the fasteners. This allows the shelf panels to be directly inserted into the assembly side of the frame rods for snap-fit ​​installation during assembly, and other shelf panels can be replaced and assembled at any time, greatly improving the flexibility of structural assembly and use.

Claims

1. A shelf structure, comprising: A plurality of frame poles, each frame pole having two mutually perpendicular facades, the inner sides of the two facades forming a combined side, and the outer sides of the two facades forming a connecting side, each facade having a plurality of buckle portions arranged sequentially from top to bottom, each buckle portion having a first buckle hole and a second buckle hole, the first buckle hole having a first buckle groove recessed downward in the middle section, and the second buckle hole having a second buckle groove recessed downward in the middle section; A plurality of fasteners, wherein the fastener is formed by bending a long plate to have a first side plate and a second side plate. The first and second side plates are horizontally bent at their upper edges to provide two upper wing plates, and the first and second side plates are horizontally bent at their lower edges to provide two lower wing plates. The upper and lower wing plates are assembled into the first and second buckle holes of the buckle part from the connecting side of the frame rod. The rear section of the upper wing plate is recessed to provide an upper limit part that overlaps and is positioned with the first buckle groove. The rear section of the lower wing plate is recessed to provide a lower limit part that overlaps and is positioned with the second buckle groove. The upper limit part has an upper clamping gap on both sides and the inner side of the first and second side plates. The lower limit part has a lower clamping gap on both sides and the inner side of the first and second side plates. Each of the multiple shelves has a snap-fit ​​part at its corner. The snap-fit ​​part is bent to have a first side and a second side. The first side has a first snap-fit ​​groove from bottom to top, and the second side has a second snap-fit ​​groove from bottom to top. The snap-fit ​​part is used to snap the shelf to the combined side of the frame rod and each of the fasteners.

2. The shelving structure as described in claim 1, wherein, The width of the first buckle hole of the frame pole is greater than the width of the second buckle hole, and the width of the first buckle groove is less than the width of the second buckle groove. The width of the upper wing plate of the fastener is greater than the width of the lower wing plate, and the width of the upper limit part of the fastener is less than the width of the lower limit part. Furthermore, the first and second fastening grooves of the fastening part gradually expand from top to bottom to form a conical groove.

3. The shelving structure as described in claim 1, wherein, The second fastener has an upper guide bevel cut at the end edge adjacent to the upper wing plate, and the two upper guide bevels are parallel. The second fastener also has a lower guide bevel cut at the end edge adjacent to the lower wing plate, and the two lower guide bevels are parallel.

4. The shelf structure as described in claim 1, wherein, The first and second sides of the fastening part are both expanded outward from top to bottom, so that the first and second sides are inclined sides that are not parallel to the two vertical surfaces of the frame rod, and the first and second sides have a first tapering gap and a second tapering gap with the two vertical surfaces respectively.

5. The shelving structure as described in claim 4, wherein, The first and second tapering gaps are connected and are fitted together with an expansion block. The expansion block has two perpendicular side blocks. The lower half of the inner side of the two side blocks tapers to form an insertion slope, and the two insertion slopes are inserted into the first and second tapering gaps to be tightened and fixed.

6. The shelving structure as described in claim 5, wherein, The second expansion block has two through holes on its upper surface between the two side blocks. The two through holes provide a means to connect the two expansion strips. Both ends of the two expansion strips are vertically bent with two connecting parts, so that one expansion strip is connected to the through holes of the two expansion blocks by means of the two connecting parts, thus completing the installation of the expansion strip.

7. The shelving structure as described in claim 1, wherein, Each of the two support poles has an upper connecting hole at the top of its facade and a lower connecting hole at the bottom of its facade. The upper connecting hole is the same as the second buckle hole and has an upper snap-fit ​​hole recessed downwards. The lower connecting hole is the same as the first buckle hole and has a lower snap-fit ​​hole recessed downwards. When the two support poles are stacked on top of each other, the upper and lower connecting holes between the two support poles are adjacent and equivalent to the buckle parts of the two facades. This allows the upper and lower connecting holes to be connected from the joint side of the support pole using the fastener. Then, a connecting piece is used to snap and fix the support pole to the joint side of the support pole using the fastener, thereby completing the height extension of the support pole.
