Description

Technical Field

[0001] This invention belongs to the technical field of turnover equipment, and particularly relates to a novel connection structure for a collapsible box and a collapsible box having the structure. Background Technology

[0002] Collapsible crates are a common tool for logistics turnover due to their lightweight nature, stackability during transport, and foldability when empty. Existing collapsible crates generally consist of a base, a body, and a lid. The body provides support and forms a cavity, while the lid typically only covers the body. Therefore, existing lids simply fit over the body, requiring removal and opening to load or unload goods or fold the crate. With increasing demands for cargo transportation, customized collapsible crates have become larger to accommodate larger loads. This design not only hinders loading and unloading but also makes folding the crate inconvenient, often requiring multiple people to work together. Summary of the Invention

[0003] The purpose of this invention is to provide a novel connection structure for a box with a panel, which facilitates the closing and opening of the box lid and body without affecting the folding of the box body.

[0004] Based on this, the present invention provides a novel connection structure for a panel box, including a connector, a supporting connector, and a guide bar;

[0005] The connector is used to connect to the housing;

[0006] The supporting connector includes a hinge seat and a connecting terminal. The hinge seat is hinged to the connecting body, and the connecting terminal is movably disposed on the hinge seat and has a snap-fit ​​end located outside the connecting body.

[0007] The guide strip is connected to the box cover. The guide strip has a sliding cavity and a sliding groove opened along the length of the guide strip. The snap-fit ​​end extends from the sliding groove into the sliding cavity.

[0008] As described above, in a novel connection structure for a panel box, the snap-fit ​​end is further provided with a rolling element that can rotate relative to the snap-fit ​​end.

[0009] As described above, in a novel connection structure for a panel box, the hinge seat has an internal mounting cavity, and the outer surface of the hinge seat has a through hole communicating with the mounting cavity. One end of the connection terminal is located inside the mounting cavity, and its snap-fit ​​end extends through the through hole to the outside of the hinge seat.

[0010] As described above, a novel connection structure for a panel box includes a hinge shaft on the connecting body and a hinge hole on the hinge seat that mates with the hinge shaft. The diameter of the hinge hole is slightly larger than the shaft diameter of the hinge shaft.

[0011] As described above, in a novel connection structure for a enclosure box, the outer peripheral surface of the rolling element is spherical, the upper side of the rolling element is a flat cut, and the flat cut has a downwardly recessed cavity. The lower side of the rolling element has a connecting hole communicating with the cavity. The snap-fit ​​end passes through the connecting hole into the cavity, and the rolling element cavity is rotatably connected to the snap-fit ​​end by a bearing.

[0012] As described above, in a novel connection structure for a coffered box, the connecting body is concave in shape, and the supporting connector is hinged to the concave opening.

[0013] As described above, a novel connection structure for a collapsible box includes a connecting plate and a connecting frame, which are connected to each other and form a clamping space for clamping and mounting on the box body.

[0014] The present invention also provides a collapsible box, comprising a box body, a box cover, and a bottom support, wherein the bottom support is disposed at the bottom of the box body, and further comprising a collapsible box cover connecting structure as described above, wherein the box body is connected to the box cover through the collapsible box cover connecting structure.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] like Figures 1 to 6 As shown, this embodiment of the invention provides a novel connection structure for a enclosure box, including a connector 2, a support connector 3, and a guide bar 4.

[0031] The connecting body 2 is used to connect to the box body, and the guide strip 4 is connected to the box cover. The box body and the box cover are connected through the connecting body connected to the box body, the guide strip connected to the box cover, and the supporting connector connecting the connecting body and the guide strip.

[0032] In this embodiment of the invention, the supporting connector 3 includes a hinge seat 31 and a connecting terminal 32. The hinge seat 31 is hinged to the connecting body 2, and the connecting terminal 32 is movably disposed on the hinge seat 31 and has a snap-fit ​​end located outside the connecting body 2. The guide strip 4 has a sliding cavity and a sliding groove opened along the length direction of the guide strip 4, and the snap-fit ​​end extends from the sliding groove into the sliding cavity. After connection, the lid can rotate relative to the box body through the hinge seat, and the lid can slide relative to the box body through the sliding of the connecting terminal in the guide strip. At the same time, the connecting terminal can also move relative to the hinge seat to facilitate the lid to close onto or detach from the box body. Therefore, the entire structure allows the lid to be slightly lifted when opening the box, greatly simplifying manual operation and reducing operational intensity.

[0033] In order to increase the smoothness of the movement of the lid relative to the box body and reduce the noise of this process, in this embodiment of the invention, the snap-fit ​​end is further provided with a rolling element 321 that can rotate relative to the snap-fit ​​end.

[0034] Specifically, the outer peripheral surface of the rolling element 321 is spherical, the upper side of the rolling element 321 is a flat cut portion, and the flat cut portion has a downwardly recessed cavity. The lower side of the rolling element 321 has a connecting hole communicating with the cavity. The snap-fit ​​end passes through the connecting hole into the cavity, and the rolling element 321 is rotatably connected to the snap-fit ​​end in the cavity through a bearing. The function of the rolling element 321 is to generate rolling friction when the cover moves relative to the box body, thereby reducing wear between components and greatly improving service life.

[0035] In this embodiment of the invention, the hinge base 31 has a mounting cavity 301 inside, and a through hole communicating with the mounting cavity 301 is provided on the outer side of the hinge base 31. One end of the connecting terminal 32 is located inside the mounting cavity 301, and its snap-fit ​​end extends out to the outside of the hinge base 31 through the through hole. This can be understood as the movement of the connecting terminal 32 relative to the hinge base 31 enabling the movement of the lid relative to the hinge base 31. Since the lid typically has a recess or step on its inner side that mates with the upper edge of the box body when it is closed, making it difficult for the lid to detach from the box body, manual operation requires first lifting the lid to completely detach it from the box body before moving it horizontally. This solution achieves this upward movement operation through the hinge base 31 and the connecting terminal 32 movably connected to the hinge base 31.

[0036] In addition, in this embodiment of the invention, after the lid is opened, a hinge seat is provided to facilitate its placement and allow it to change from a horizontal position when closed to an inclined or upright position. In this design, the connecting body 2 has a hinge shaft 21, and the hinge seat 31 has a hinge hole 302 that mates with the hinge shaft 21. The diameter of the hinge hole 302 is slightly larger than the shaft diameter of the hinge shaft 21. This allows the hinge seat 31 to have more space in the radial direction. Since the total volume of the lid is much larger than the hinge seat 31, it is difficult for the lid to press the hinge seat 31 tightly against the hinge shaft 21, preventing it from rotating.

[0037] In this embodiment of the invention, the connecting body 2 is generally concave, and the supporting connecting member 3 is hinged to its concave opening. Its structure is simple, and the hinge seat 31 allows the connecting body 2 to be embedded in the periphery of the box, resulting in a more aesthetically pleasing product appearance.

[0038] In addition, in this embodiment of the invention, the connecting body 2 includes a connecting plate 201 and a connecting frame 202, which are connected to each other and form a clamping space for clamping and mounting on the housing. Its structure is simple and easy to install.

[0039] This invention also provides a pallet box, comprising a box body 91, a box cover 92, and a bottom support 93. The bottom support 93 is located at the bottom of the box body 91. The invention also includes a box cover connecting structure, through which the box body 91 is connected to the box cover 92. To ensure smoother movement of the box cover 92, this design typically includes two sets of connecting bodies 2 and supporting connectors 3 on the same side wall of the box body 91. Similarly, double parallel guide strips 4 are provided on the box cover 92. Of course, more sets of connecting bodies 2, supporting connectors 3, and a corresponding number of guide strips 4 can be provided depending on the size of the pallet box.

[0040] The operation of this invention is as follows: when the lid 92 is closed on the box body 91, the operator only needs to lift the lid 92 as a whole. At this time, the lid 92 drives the connecting terminal 32 to extend outward relative to the hinge seat 31. Then, the lid 92 is tilted. Utilizing the weight of the lid and the guiding and limiting effects of the guide strip 4 and the supporting connecting member 3, the lid 92 moves automatically relative to the box body 91 without detaching from the box body, thus reducing the intensity of operation. In addition, after the lid 92 is opened, it can be in a basically upright state on the side wall of the box body 91, so it can also be folded together with the box body 91.

[0041] In the embodiment of the present invention, the specific structure of the box body 91 is as follows: the box body 91 at least includes a front side plate 911, a rear side plate 912, a left side plate 913 and a right side plate 914 that are sequentially connected and enclosed. The left side plate 913 and the right side plate 914 have folding positions, and the front side plate 911, the rear side plate 912, the left side plate 913 and the right side plate 914 can all rotate along the connection points to achieve folding.

[0042] In the embodiment of the present invention, a concave cavity is provided on the bottom support 93. After the box body 91 is folded, it can be directly placed into the concave cavity. In addition, in order to facilitate the positioning and folding of the box cover, a limiting step is provided on the inner peripheral wall of the concave cavity. In this way, when placing the box cover, the bottom of the box cover contacts the limiting step, so that the box cover does not press on the box body 91, preventing damage to the box during transportation.

[0043] In the embodiment of the present invention, a first long groove 921, a second long groove 922 and a third long groove 923 that are recessed downward are provided on the upper end surface of the box cover 92. Among them, the first long groove 921, the second long groove 922 and the third long groove 923 are arranged in parallel in a "Sichuan" character shape; for the common Sichuan character-shaped bottom feet, three strip-shaped long grooves are provided for them to be embedded, so that the corrugated box can have a certain limiting effect on the bottom feet of the upper corrugated box when stacked.

[0044] In addition, in order to facilitate the placement of the bottom feet of a single plurality of feet in this solution, a foot pad position 95 with a width greater than the corresponding groove width is provided in each of the first long groove 921, the second long groove 922 and the third long groove 923. The first long groove 921, the second long groove 922 and the third long groove 923 are used to accommodate the strip-shaped bottom feet 992 at the bottom of the corrugated box, and the foot pad position 95 is used to accommodate the feet 991 at the bottom of the corrugated box. It corresponds to the strip-shaped bottom feet to be embedded and installed by setting the concave long grooves on the upper end surface of the box cover, and at the same time, a foot pad position is added in the long groove to accommodate the foot-type bottom feet, so that when the box cover of this solution is stacked and placed after the corrugated box is folded, it can limit the upper corrugated box and is not easy to displace during transportation.

[0045] In the embodiment of the present invention, the first long groove 921, the second long groove 922 and the third long groove 923 penetrate through the left and right sides of the box cover 92. Moreover, the first long groove 921 is located on the front side of the box cover 92, the third long groove 923 is located on the rear side of the box cover 92, and the second long groove 922 is located between the first long groove 921 and the third long groove 923. One side of the first long groove 921 penetrates to the front side of the box cover 92, and one side of the third long groove 923 penetrates to the rear side of the box cover 92. Its structure is simple and it is adapted to the use of the current Sichuan character-shaped bottom support on the market.

[0046] Of course, this solution can also be adapted to more uses such as the Japanese character shape or the field character shape. Only on the basis of the above, add long grooves that penetrate the front and rear sides to correspond to the shape for use.

[0047] In this embodiment of the invention, each long slot is provided with three equally spaced foot positions 95, with each foot position 95 distributed on the left, middle, and right sides of the corresponding long slot. That is, a single box cover is provided with nine such foot positions 95, and the nine such foot positions 95 are evenly distributed in a nine-square grid, which is also the structure of a common support-type base on the market.

[0048] In addition, in this embodiment of the invention, a GPS mounting part 96 is provided on the upper side of the box cover 92, and the GPS mounting part 96 is located between the second long groove 922 and the third long groove 923. To meet the need for positional positioning in the pallet box, the GPS kit can be directly embedded into the mounting part 96 of the box cover. Furthermore, since the GPS mounting part 96 is also embedded into the box cover, it is less likely to be touched when stacked.

[0049] In this embodiment of the invention, to facilitate drainage, the GPS mounting part 96 is further provided with a notch 961 that connects the GPS mounting part 96 to the second elongated groove 922. Furthermore, the notch 961 connects to the foot pad 95 in the middle of the second elongated groove 922.

[0050] In this design, the top of the lid also has a logo area, which can be used to affix labels or to reserve space for printing labels. For easy display, logo areas are also provided on the sides of the lid.

[0051] In addition, to facilitate the handling of the lid, a handle 962 is provided on the upper side of the foot position 95 in the middle of the first long slot 921 and the third long slot 923.

[0052] This invention provides a novel connection structure for a box with a protective panel. The box body and the box cover are connected by a connector that connects to the box body, a guide strip that connects to the box cover, and a support connector that connects the connector and the guide strip. After connection, the box cover can rotate relative to the box body through a hinge seat. The box cover can slide relative to the box body by sliding the connecting terminal within the guide strip. At the same time, the connecting terminal can also move relative to the hinge seat to facilitate the box cover to be closed on the box body or to be detached from the box body. Therefore, the entire structure allows the box body to be opened by only slightly lifting the box cover, which greatly simplifies manual operation and reduces the intensity of operation.
