Description

Technical Field

[0001] This utility model relates to the field of folding containers, and in particular to a folding container and a side plate connection structure. Background Technology

[0002] With the rapid development of China's economy, the logistics industry has also flourished. Compared to the transportation of general goods, liquid transportation places higher demands on transportation equipment. Generally, packaging capable of storing and transporting various non-hazardous liquids or bulk goods is called a container. Compared to traditional transport packaging methods, collapsible containers can significantly reduce costs associated with loading, unloading, packaging, transportation, and material management, offering substantial economic advantages. Therefore, they are more widely used in various fields such as chemicals, petroleum, food, feed, and agricultural products.

[0003] Common existing structures include: (a) A structure in which the base and side panel are connected by a metal pivot. The base has corresponding holes on its side, through which the metal pivot passes to connect the base and the side panel. The holes on the side panel are then plugged, allowing the side panel to rotate freely. The advantage of this connection method is that the side panel will not fall off. However, due to its complex structure, it can cause inconvenience in assembly and use.

[0004] (ii) The connection structure between the base and the side panel features a built-in plastic snap-fit ​​hinge. Relying on the elastic pre-tensioning effect of the plastic, the side panel engages with the matching structure on the base during use, and then the side panel unfolds into an upright state. This type of hinge is subjected to shear stress over a long period. After repeated use, the engaging parts will wear down, reducing or even eliminating the original design effect of the side panel's upright position due to the elastic pre-tensioning effect of the plastic. When the side panel changes from a folded state to an unfolded upright state, there is a risk of tipping over. Once damaged, it becomes difficult to repair and has poor practicality.

[0005] Therefore, how to develop a new type of folding container and side plate connection structure has become an urgent problem for those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a side plate connection structure that solves the problems of low strength and overall safety of existing side plate connection structures.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This utility model discloses a side plate connection structure, including a base body and a first side plate. The base body has side wall structures on its four sides, and the top of the side wall structures has a base guide groove and a base positioning groove. The bottom of the first side plate has an extension plate that mates with the base guide groove. The extension plate has protrusions on both sides. The base guide groove has square blocks and edge grooves that mate with the protrusions. The bottom of the first side plate has a protrusion that mates with the base positioning groove.

[0008] Furthermore, the top of the base guide groove has an opening that mates with the protrusion; the extension plate is rotatably disposed within the base guide groove via the protrusion.

[0009] Furthermore, the back plate of the base guide groove is provided with protruding ribs that cooperate with the extension plate.

[0010] Furthermore, the front and rear faces of the extension plate are provided with inclined surfaces that mate with the opening.

[0011] Furthermore, the inclined surface is provided with a groove that mates with the raised rib.

[0012] Furthermore, wedge-shaped blocks are provided on both sides of the base positioning groove, and wedge-shaped blocks corresponding to the wedge-shaped blocks are provided on both sides of the protrusion.

[0013] Furthermore, the upper surface of the wedge block engages with the lower surface of the wedge block.

[0014] Furthermore, the length of the extension plate is greater than the length of the protrusion.

[0015] A folding container further includes a second side panel, which is disposed adjacent to the first side panel.

[0016] Compared with the prior art, the beneficial technical effects of this utility model are as follows: This utility model relates to a folding container and side panel connection structure. Through the connection and fixation of the base body with the first and second side panels, and the staggered arrangement of the base guide groove and base positioning groove, the stress on the positioning and installation structure is distributed, reducing the possibility of structural damage during installation and folding. This enhances the expandability of the side panels, enabling convenient assembly and folding of the container, and ensuring the firmness and accuracy of the container connection and positioning. In summary, this utility model's folding container and side panel connection structure is ingeniously designed, simple in structure, and practical in function, effectively solving the problem of low strength and overall safety of the side panel connection structure in existing folding containers.

Detailed Implementation

[0019] like Figures 1 to 9 As shown, a folding container includes a base body 001, a first side plate 002, and a second side plate 003, wherein the second side plate 003 is disposed adjacent to the first side plate 002. The two first side plates 002 and the two second side plates 003 together with the base body 001 form a container.

[0020] The base body 001 has side wall structures on its four sides, and a base guide groove 101 and a base positioning groove 102 are formed on the inner side of the top of the side wall structure. The base guide groove 101 and the base positioning groove 102 are staggered. The connection structure between the first side plate 002 and the base body 001 is the same as the connection structure between the second side plate 003 and the base body 001.

[0021] The bottom end of the first side plate 002 is provided with an extension plate 201 that mates with the base guide groove 101. The extension plate 201 can be inserted into the base guide groove 101. Protrusions 204 are provided on both sides of the extension plate 201. A retaining groove 104 that mates with the protrusions 204 is provided in the base guide groove 101. The cross-section of the base guide groove 101 is "[" shaped. The upper end of the retaining groove 104 is provided with a square stop block 105 for preventing the protrusions 204 on the extension plate 201 from falling out.

[0022] The top of the base guide groove 101 has an opening 106 that mates with the protrusion 204. The opening 106 is used for the protrusion 204 on the extension plate 201 to move in and out. The maximum size of the protrusion 204 is larger than the distance between the openings 106 at both ends of the base guide groove 101. The extension plate 201 is rotatably mounted in the base guide groove 101 via the protrusion 204. The back of the base guide groove 101 is provided with a rib 103. The upper end of the rib 103 is provided with a ramp to facilitate the entry of the extension plate 201. The extension plate 201 is provided with a groove 205 that mates with the rib 103.

[0023] The protruding rib 103 serves to increase the strength of the back plate of the base guide groove 101. The front and rear faces of the extension plate 201 are provided with inclined surfaces 203 that cooperate with the opening 106.

[0024] The bottom end of the first side plate 002 is provided with a protrusion 202 that mates with the base positioning groove 102. The protrusion 202 can be embedded in the base positioning groove 102.

[0025] The base positioning groove 102 has wedge-shaped blocks 107 on both sides, with a through-hole in the middle, forming a "⊥" shape. The protrusion 202 has wedge-shaped blocks 206 on both sides corresponding to the wedge-shaped blocks 107. The wedge-shaped blocks 107 are hollow, with a sloping lower part, and are adapted to the wedge-shaped blocks 206 at both ends of the protrusion 202.

[0026] The upper surface of the wedge block 206 engages with the lower surface of the wedge block 107.

[0027] The length of the extension plate 201 is greater than the length of the protrusion 202, so that when the extension plate 201 is inserted into the base guide groove 101 from the top, the protrusion 202 and the base positioning groove 102 do not interfere.

[0028] like Figures 6 to 8 As shown, taking the installation of the first side panel 002 as an example: First, rotate the first side plate 002 to tilt it at 60°. At this time, the inclined surface 203 on the extension plate 201 of the first side plate 002 is parallel to the back plate of the base guide groove 101, and the plane 207 on the protrusions 204 on both sides of the top of the extension plate 201 is also parallel to the back plate of the base guide groove 101.

[0029] At this time, the distance between the inclined surface 203 on the extension plate 201 and the flat surface 207 on the protrusion 204 is smaller than the openings 106 at both ends of the base guide groove 101.

[0030] When the first side plate 002 is moved downward in the vertical direction, the protrusions 204 at both ends of the extension plate 201 enter the openings 106 at both ends of the base guide groove 101. When the top of the extension plate 201 touches the rib 103 on the back of the base guide groove 101, the first side plate 002 is rotated inward towards the base body 001. At this time, the protrusions 204 on both sides of the top of the extension plate 201 enter the retaining grooves 104 at both ends of the base guide groove 101 along the slope of the rib 103 on the side wall of the base guide groove 101.

[0031] Place the first side panel 002 horizontally; this completes the installation of the first side panel 002.

[0032] like Figure 9 As shown, when the first side plate 002 is upright, the protrusions 204 at both ends of the extension plate 201 on the first side plate 002 rotate within the retaining grooves 104 at both ends of the base guide groove 101. Simultaneously, the protrusion 202 on the bottom side of the first side plate 002 is inserted into the base positioning groove 102, and the wedge-shaped blocks 206 at both ends of the protrusion 202 are adapted to the wedge-shaped stops 107 of the base positioning groove 102. At this time, the first side plate 002 is vertically fixed.

[0033] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
