Description

Technical Field

[0001] The utility model relates to a connection structure, in particular to a storage rack connection structure. Background Art

[0002] Existing shelf structures for storing items, such as the folding shoe rack described in Chinese Utility Model Patent Publication No. CN217851896U, primarily comprise an upper base plate and a lower base plate, with left and right side panels connected between the upper and lower base plates. Both left and right side panels are X-shaped flat plates. Once connected, the left and right side panels are flush with the sides of the base plate. The side panels, flush with the sides of the base plate, support the upper and lower base plates. This can easily cause the upper and lower base plates to wobble, resulting in poor support stability.

[0003] In order to solve the above-mentioned problem of poor support stability, the Chinese utility model with announcement number CN217851896U also adopted a technical solution of additionally installing a rear side plate between the upper base plate and the lower base plate, and its stability was greatly improved. However, since the left and right side plates and the rear side plate of the X-shaped flat structure are respectively installed on the left, right and rear sides of the entire folding shoe rack, the entire shoe rack only has a front opening, and the convenience of placing and taking shoes is relatively low. Utility Model Content

[0004] In view of this, an object of the present invention is to provide a storage rack connection structure, which can not only greatly improve the structural strength of the storage rack, but also effectively improve the convenience of use of the storage rack.

[0005] In order to solve the above technical problems, the technical solution of the utility model is:

[0006] A storage rack connection structure includes an upper storage plate and a lower storage plate, wherein the upper storage plate includes upper plate sides, and two adjacent upper plate sides intersect to form an upper plate corner; and the lower storage plate includes lower plate sides, and two adjacent lower plate sides intersect to form a lower plate corner.

[0007] Also included is a connecting portion, the connecting portion being located between the upper storage plate and the lower storage plate;

[0008] The connecting portion includes a first connecting member and a second connecting member, the first connecting member and the second connecting member are connected by a deformable connecting member, both ends of the first connecting member and the second connecting member are provided with a first plug-in member, and the upper plate side of the upper storage plate and the lower plate side of the lower storage plate are provided with a second plug-in member;

[0009] The first connector and the second connector are folded together via a deformable connector, the first connector on the connecting portion is correspondingly plugged into the second connector, and the folding points between the first connector and the second connector correspond to the upper plate corner and the lower plate corner respectively.

[0010] With the above technical solution, when the upper storage plate and the lower storage plate are connected by the connecting portion, from the perspective of structural strength, the two ends of the connecting portion respectively abut against the corners of the upper plate and the lower plate, and the first connectors at one end of the first connector and the second connector are respectively plugged into the second connectors on the two adjacent sides of the upper plate, and the first connectors at the other end of the first connector and the second connector are respectively plugged into the second connectors on the two adjacent sides of the lower plate. With this structure, regardless of the horizontal or vertical thrust applied to the storage rack, the structure remains stable.

[0011] From the perspective of ease of use, the connection portion only exists between the upper corner of the upper storage plate and the lower corner of the lower storage plate. The entire storage rack is formed with multiple openings, making it more convenient to place and take items.

[0012] Preferably, the deformable connecting member comprises a bendable plastic sheet, and the plastic sheet is integrally injection-molded between the first connecting member and the second connecting member.

[0013] Through the above technical solution, firstly, the plastic sheet, the first connecting member and the second connecting member can be formed by one-time injection molding, which has high production efficiency; secondly, by adopting the bendable plastic sheet solution, smoother bending can be achieved between the first connecting member and the second connecting member.

[0014] Preferably, a fixing groove is provided on the side wall of the first connecting member, and a fixing block is provided on the side wall of the second connecting member;

[0015] When the first connecting member and the second connecting member are relatively folded, the fixing block is inserted into the fixing groove.

[0016] Through the above technical solution, firstly, the angular stability of the folding of the first connecting member and the second connecting member can be ensured; secondly, when the connecting portion is connected between the upper storage plate and the lower storage plate, the fixing block is inserted into the fixing groove, the connection stability between the first connecting member and the second connecting member is higher, and the supporting stability of the connecting portion for the upper storage plate and the lower storage plate is higher.

[0017] Preferably, the first connector includes a connector block, and the second connector includes a connector slot provided on the side of the upper plate and the side of the lower plate, and the connector block is plugged into the connector slot.

[0018] Through the above technical solution, when the connecting part needs to be connected to the upper storage plate and the lower storage plate, the plug-in block is plugged into the plug-in slot, which not only has high connection stability but also makes disassembly and assembly more convenient.

[0019] Preferably, the first connector further comprises an elastic block provided on the plug-in block, the elastic block is provided with a hook portion, and the groove wall of the fixing groove is provided with a hook groove;

[0020] When the plug-in block is plugged into the plug-in slot, the hook portion is hooked into the hook slot.

[0021] Through the above technical solution, when the plug-in block is plugged into the plug-in slot, the hook portion can be directly hooked into the hook slot, which can effectively improve the plug-in connection stability between the plug-in block and the plug-in slot.

[0022] Preferably, the plug-in block is provided with an elastic groove, one end of the elastic block is connected to the groove wall of the elastic groove, and the hook is provided on the free end of the elastic block.

[0023] Through the above technical solution, when the plug-in block is plugged into the plug-in slot, the free end of the spring block can be deformed into the spring slot until the hook portion is opposite to the hook slot, and the spring block will drive the hook portion to hook into the hook slot to achieve mutual hooking.

[0024] Preferably, both ends of the first connecting member and the second connecting member are respectively abutting ends, the cross-sectional area of the abutting ends is larger than the cross-sectional area of the middle position of the first connecting member and the second connecting member, and the two abutting ends are respectively against the upper plate side of the upper storage plate and the lower plate side of the lower storage plate.

[0025] Through the above technical solution, on the one hand, the effective contact area between the two ends of the connecting part and the upper storage plate and the lower storage plate is increased, thereby effectively improving the support stability; on the other hand, the middle position of the first connecting member and the second connecting member is relatively small, which can make the mouth of the storage rack larger, and the convenience of placing and taking items is further improved.

[0026] Preferably, the plug-in block is located on the abutting end.

[0027] Through the above technical solution, the abutting end abuts against the upper plate side of the upper storage plate and the lower plate side of the lower storage plate, and the plug-in block is also plugged into the plug-in slot, and the overall structural stability is high.

[0039] The connecting portion 3 includes a first connecting member 31 and a second connecting member 32. The first and second connecting members 31 and 32 are connected via a deformable connecting member 33. The deformable connecting member 33 comprises a bendable plastic sheet 331, which is integrally injection-molded between the first and second connecting members 31 and 32. The plastic sheet 331 can bend and deform to a certain extent, allowing the first and second connecting members 31 and 32 to be flexed freely.

[0040] First connectors 4 are provided at both ends of the first connecting member 31 and both ends of the second connecting member 32, and second connectors 5 are provided on the upper plate side 11 of the upper storage plate 1 and the lower plate side 21 of the lower storage plate 2. The second connector 5 on the upper plate side 11 of the upper storage plate 1 has the same structure as the second connector 5 on the lower plate side 21 of the lower storage plate 2.

[0041] The first connecting member 31 and the second connecting member 32 are folded together by a deformable connecting member 33, and the first plug-in connector 4 on the connecting portion 3 is correspondingly plugged into the second plug-in connector 5. The folding points between the first connecting member 31 and the second connecting member 32 correspond to the upper plate corner 12 and the lower plate corner 22 respectively.

[0042] A fixing groove 6 is provided on the side wall of the first connecting member 31, and a fixing block 7 is provided on the side wall of the second connecting member 32; when the first connecting member 31 and the second connecting member 32 are relatively folded, the fixing block 7 is inserted into the fixing groove 6, which helps to improve the structural strength between the first connecting member 31 and the second connecting member 32.
