[0036] Some furniture is assembled from panels, either partially or entirely. Intersecting panels are usually connected and fixed with threaded fasteners (such as screws and bolts). During assembly, the threaded fasteners require tools and are prone to damage to the panels. As a result, the operation is cumbersome, the assembly efficiency is low, and it is not conducive to disassembly and reassembly.

[0037] This utility model provides a connecting device for connecting at least two intersecting panels, simplifying assembly and facilitating panel disassembly, effectively reducing panel damage. This utility model also provides a panel-type connecting assembly, which uses the connecting device to connect at least two intersecting panels. The connecting device engages with the panels within the connecting angle formed by their intersection, enabling convenient assembly. The engagement method facilitates panel disassembly and reduces damage. Using this panel-type connecting assembly for partial or overall furniture assembly is simple and convenient, minimizes damage to the panels, effectively improves assembly efficiency, and facilitates repeated assembly and disassembly. The following description, in conjunction with the accompanying drawings, describes the embodiments of this utility model.

[0038] Please see Figure 1 The plate-type connecting assembly of this utility model embodiment includes a connecting device and at least two intersecting plates 300. The intersection of the at least two plates 300 defines a connecting angle, and the connecting device is located within the connecting angle for connecting the intersecting plates 300.

[0039] The connecting device includes a connecting element 100 and a plug-in element 200. The connecting element 100 includes at least two intersecting connecting surfaces, each adapted to abut against a corresponding plate 300. Each connecting surface is provided with a first recess 140, and each plate 300 is provided with a second recess 340 corresponding to the first recess 140. The plug-in element 200 includes a first connecting portion 210 and a second connecting portion 220 connected together. The first connecting portion 210 is adapted to be engaged within the first recess 140, and the second connecting portion 220 is exposed outside the first recess 140. The second connecting portion 220 is adapted to be engaged within the second recess 340 on the corresponding plate 300. By inserting and engaging the first connecting portion 210 of the plug-in element 200 into the first recess 140, and by inserting and engaging the second connecting portion 220 of the plug-in element 200 into the second recess 340 on the corresponding plate 300, the connection and fixation between the connecting element 100 and the plate 300 are achieved.

[0040] Therefore, in this invention, when assembling adjacent plates 300, it is only necessary to insert the plug-in element 200 into the second recess 340 on the plate 300 and the first recess 140 on the connecting element 100, avoiding the use of installation tools. Compared with the prior art, this avoids the cumbersome operation of screw installation, making the operation simple and convenient, and greatly improving installation efficiency. Furthermore, because the plug-in element 200 is inserted, even with repeated disassembly and assembly, the plate is less likely to be damaged due to secondary disassembly, resulting in high reliability.

[0041] In the plate-type connection assembly, the plate 300 and the corresponding connecting surface of the connecting device are abutted together. Specifically, a second recess 340 is provided on the side of the plate 300 facing the connecting element 100, corresponding to the position of the first recess 140. The second connecting portion 220 of the plug-in element 200 is adapted to be snapped into the second recess 340. The connecting element 100 is detachably connected to the corresponding plate 300 via the plug-in element 200. During assembly, the plate 300 and the second connecting portion 220 do not require drilling with bolts or screws, thus improving assembly convenience and minimizing damage to the plate 300 when disassembly and reassembly are necessary. In one embodiment of the connecting device, a first recess 140 extends to a predetermined length and passes through the connecting element 100 along its extending direction to form a first opening 144. A first connecting portion 210 is adapted to be inserted into the first recess 140 from the first opening 144. After the first connecting portion 210 is inserted and engaged in the first recess 140, a second connecting portion 220 is exposed outside the first recess 140. By withdrawing the first connecting portion 210 along the first recess 140 from the first opening 144, the plug-in element 200 and the connecting element 100 can be detached.

[0042] Correspondingly, the second recess 340 on the plate 300 can extend to a predetermined length, and the extension direction of the first recess 140 is consistent with the extension direction of the second recess 340 on the corresponding plate 300. The second recess 340 extends through one side edge of the plate 300 to form a second opening 345. The second connecting part 220 is adapted to be inserted into the second recess 340 from the second opening 345 and engaged in the second recess 340. The second connecting part 220 can be disassembled from the plate 300 by exiting from the second opening 345 along the second recess 340.

[0043] When assembling the plate 300, connecting element 100, and plug-in element 200, the first connecting portion 210 of the plug-in element 200 can be inserted into the first recess 140 of the connecting element 100, so that the first connecting portion 210 is engaged with the first recess 140, thereby forming an exposed second connecting portion 220 on the connecting surface 110. Then, the second connecting portion 220 is inserted into the second recess 340 of the plate 300, so that the second connecting portion 220 is engaged with the second recess 340. Alternatively, the second connecting portion 220 of the plug-in element 200 can be engaged with the second recess 340 of the plate 300, thereby forming an exposed first connecting portion 210 on each plate 300, and then the first connecting portion 210 is engaged with the corresponding first recess 140 of the connecting element 100.

[0044] When disassembling panel 300, panel 300 can be detached from connector 200. The remaining exposed second connecting portion 220 on connector 100 can be used to re-engage with the second countersunk groove 340 of the current panel 300 or with the second countersunk groove 340 of other panels 300. Alternatively, when disassembling panel 300, panel 300 and connector 200 can be detached together from connector 100. The remaining exposed first connecting portion 210 on panel 300 can be used to re-engage with the first countersunk groove 140 on the current connecting surface or with the first countersunk groove 140 on other connecting surfaces.

[0045] In the connecting device of this application embodiment, the connecting element 100 may include two intersecting connecting surfaces or three intersecting connecting surfaces. The extension directions of the first grooves 140 on two different connecting surfaces may be parallel to each other or perpendicular to the same axis. Thus, the connecting element 200 can be used to connect at least two intersecting plates 300. The three intersecting connecting surfaces can be used to connect three intersecting plates 300 respectively. By reasonably arranging the number of intersecting connecting surfaces on the connecting element 100 and the extension directions of the first grooves 140 on different connecting surfaces, various assembly methods of the plates 300 and the connecting device can be realized.

[0046] In some embodiments, the connecting element 100 includes two intersecting connecting surfaces, and the extension direction of the first groove 140 on the two connecting surfaces is perpendicular to the same axis. See also... Figure 1 and Figure 2 As shown, the two intersecting connecting surfaces can be defined as a first connecting surface 110 and a second connecting surface 120, respectively, intersecting at a first axis. First grooves 140 on the first connecting surface 110 and the second connecting surface 120 are perpendicular to the first axis and extend along their respective directions through the edge of the connecting element 100 opposite to the first axis, forming a first opening 144. When the plug-in element 200 and the connecting element 100 are assembled, the first connecting portion 210 of the plug-in element 200 can be inserted from each first opening 144 into the corresponding first groove 140 in a direction perpendicular to the first axis, and engage with the first groove 140.

[0047] Correspondingly, the plate-type connecting assembly includes two intersecting plates 300, which can be defined as a first plate 310 and a second plate 320, respectively. The first plate 310 has a plate surface parallel to the first connecting surface 110, and the second plate 320 has a plate surface parallel to the second connecting surface 120. The plate surfaces of the first plate 310 and the second plate 320 are respectively provided with second recesses 340 whose extension direction is consistent with the first recesses 140 on the corresponding connecting surfaces. When the plate 300 is assembled with the plug-in element 200, the second connecting portion 220 of the plug-in element 200 can be inserted into the corresponding second recesses 340 from each second opening 345 in a direction perpendicular to the first axis, and engage with the second recesses 340.

[0048] During assembly, the plug-in components 200 can be first snapped onto the first connecting surface 110 and the second connecting surface 120 to form exposed second connecting portions 220. Then, the second opening 345 on the first plate 310 is aligned with the second connecting portion 220 on the first connecting surface 110, and the first plate 310 is pushed along the extending direction of the second recess 340. Similarly, the second opening 345 on the second plate 320 is aligned with the second connecting portion 220 on the second connecting surface 120, and the first plate 310 is pushed along the extending direction of the second recess 340. Pushing the second plate 320 will engage the second recess 340 on the first plate 310 and the second plate 320 with the second connecting part 220. After engagement, the ends of the first plate 310 and the second plate 320 that intersect each other will abut against the first connecting surface 110 and the second connecting surface 120, respectively. Each plug-in element 200 will effectively constrain the position of the corresponding plate 300 in the direction along the first axis and in the direction perpendicular to the corresponding connecting surface.

[0049] During disassembly, the first plate 310 and the second plate 320 can be removed from the plug-in element 200 in a direction perpendicular to the first axis, or the first plate 310 or the second plate 320 and the plug-in element 200 can be removed together from the connecting element 100 in a direction perpendicular to the first axis.

[0050] As an example, see Figure 1 The first connecting surface 110 and the second connecting surface 120 are two intersecting surfaces parallel to the vertical direction 600. The first axis extends along the vertical direction 600. The first groove 140 on the first connecting surface 110 extends along the first horizontal direction 400. The first groove 140 on the second connecting surface 120 extends along the second horizontal direction 500. The first horizontal direction 400 and the second horizontal direction 500 intersect with the vertical direction 600. The first plate 310 and the second plate 320 can be assembled along the first horizontal direction 400 and the second horizontal direction 500, respectively. The plug-in element 200 effectively constrains the position of the corresponding plate 300 in the vertical direction 600 and in the direction perpendicular to the corresponding connecting surface.

[0051] In some embodiments, where the connecting element 100 includes two intersecting connecting surfaces, the extending directions of the first recesses 140 on the two different connecting surfaces can also be parallel to each other. For example, the first connecting surface 110 and the second connecting surface 120 intersect at a first axis, and the first recesses 140 on the first connecting surface 110 and the second connecting surface 120 are respectively parallel to the first axis and respectively extend through one side edge of the connecting element 100 along their respective extending directions to form a first opening 144. When the plug-in element 200 and the connecting element 100 are assembled, the first connecting portion 210 of the plug-in element 200 can be snapped into the corresponding first recess 140 from each first opening 144 in a direction parallel to the first axis.

[0052] Correspondingly, the plate-type connecting assembly includes two intersecting plates 300, which can be defined as a first plate 310 and a second plate 320, respectively. The first plate 310 has a plate surface parallel to the first connecting surface 110, and the second plate 320 has a plate surface parallel to the second connecting surface 120. The plate surfaces of the first plate 310 and the second plate 320 are respectively provided with second recesses 340 whose extension direction is consistent with the first recesses 140 on the corresponding connecting surfaces. When the plate 300 is assembled with the plug-in element 200, the second connecting portion 220 of the plug-in element 200 can be engaged with the corresponding second recesses 340 from each second opening 345 in a direction parallel to the first axis.

[0053] During assembly, firstly, insert components 200 are snapped onto the first connecting surface 110 and the second connecting surface 120 to form exposed second connecting portions 220. Then, the second opening 345 on the first plate 310 is aligned with the second connecting portion 220 on the first connecting surface 110, and the first plate 310 is pushed along the extending direction of the second recess 340. Similarly, the second opening 345 on the second plate 320 is aligned with the second connecting portion 220 on the second connecting surface 120, and the second plate 320 is pushed along the extending direction of the second recess 340. This allows the first plate 310 to be assembled. The second recess 340 on the first plate 310 and the second plate 320 engages with the second connecting part 220. After engagement, the ends of the first plate 310 and the second plate intersect each other, or the end of one of the plates 300 in the first plate 310 and the second plate 320 intersects with the middle of the surface of the other plate 300. The surfaces of the first plate 310 and the second plate 320 abut against the first connecting surface 110 and the second connecting surface 120, respectively. Each plug-in element 200 effectively constrains the position of the corresponding plate 300 in a direction perpendicular to the first axis.

[0054] During disassembly, the first plate 310 and the second plate 320 can be removed from the plug-in element 200 in a direction parallel to the first axis, or the first plate 310 or the second plate 320 and the plug-in element 200 can be removed together from the connecting element 100 in a direction parallel to the first axis.

[0055] As an example, the first connecting surface 110 and the second connecting surface 120 are two intersecting surfaces parallel to the vertical direction 600. The first axis extends along the vertical direction 600. The first grooves 140 on the first connecting surface 110 and the second connecting surface 120 are respectively extended along the vertical direction 600. The first plate 310 and the second plate 320 can be assembled along the vertical direction 600 respectively. The plug-in element 200 effectively constrains the position of the corresponding plate 300 in the direction perpendicular to the first axis.

[0056] Please see Figure 1 and Figure 2 As shown, in the scheme where the connecting element 100 includes two intersecting connecting surfaces, in addition to the first connecting surface 110 and the second connecting surface 120 with the first recess 140, the connecting element 100 may also include a third connecting surface 130 without the first recess 140. The third connecting surface 130 intersects with the first connecting surface 110 and the second connecting surface 120 respectively, and can serve as a reinforcing structure between the first connecting surface 110 and the second connecting surface 120.

[0057] Please see Figure 3 and Figure 4As shown, in some embodiments, the connecting element 100 may include three intersecting connecting surfaces, wherein the extension direction of the first groove 140 on any two connecting surfaces is perpendicular to the same axis. The three intersecting connecting surfaces may be defined as a first connecting surface 110, a second connecting surface 120, and a third connecting surface 130, respectively. The first connecting surface 110 intersects with the second connecting surface 120 at a first axis and with the third connecting surface 130, respectively. The first connecting surface 110 and the third connecting surface 130 intersect at a second axis, and the second connecting surface 120 and the third connecting surface 130 intersect at a third axis. The first grooves 140 on the first connecting surface 110 and the second connecting surface 120 are perpendicular to the third axis and extend through the edge of the connecting element 100 away from the third axis along their respective extension directions to form a first opening 144. The first grooves 140 on the first connecting surface 110 and the third connecting surface 130 are perpendicular to the first axis and extend through the edge of the connecting element 100 away from the first axis along their respective extension directions to form a first opening 144. The first recesses 140 on the second connecting surface 120 and the third connecting surface 130 are perpendicular to the second axis. When the plug-in element 200 and the connecting element 100 are assembled, the first connecting portion 210 of the plug-in element 200 can be snapped into the corresponding first recess 140 from each first opening 144 in a direction perpendicular to each axis.

[0058] Correspondingly, the plate-type connecting assembly includes three intersecting plates 300, which can be defined as a first plate 310, a second plate 320, and a third plate 330, respectively. The first plate 310 intersects with the second plate 320 and also with the third plate 330. The first plate 310 has a plate surface parallel to the first connecting surface 110, the second plate 320 has a plate surface parallel to the second connecting surface 120, and the third plate 330 has a plate surface parallel to the third connecting surface 130. The plate surfaces of the first plate 310, the second plate 320, and the third plate 330 are respectively provided with second recesses 340 whose extension direction is consistent with the first recesses 140 on the corresponding connecting surfaces. When the plate 300 is assembled with the plug-in element 200, the second connecting portion 220 of the plug-in element 200 can be snapped into the corresponding second recess 340 from each second opening 345 in a direction perpendicular to each axis.

[0059] During assembly, firstly, insert components 200 can be snapped onto the first connecting surface 110, the second connecting surface 120, and the third connecting surface 130 to form exposed second connecting portions 220. Then, align the second opening 345 on the third plate 330 with the second connecting portion 220 on the third connecting surface 130, and push the third plate 330 along the extending direction of the second countersunk groove 340. Next, align the second opening 345 on the first plate 310 with the second connecting portion 220 on the first connecting surface 110, and push the first plate 310 along the extending direction of the second countersunk groove 340 on the first plate 310. Finally, align the second opening 345 on the second plate 320 with the second connecting portion 220 on the second connecting surface 120. The connecting part 220 pushes the second plate 320 along the extension direction of the second recess 340 on the second plate 320, so that the second recess 340 on the first plate 310, the second plate 320 and the third plate 330 can be engaged with the second connecting part 220. After engagement, the first plate 310, the second plate 320 and the third plate 330 intersect at their ends. The plate surfaces of the first plate 310, the second plate 320 and the third plate 330 abut against the first connecting surface 110, the second connecting surface 120 and the third connecting surface 130 respectively. Each plug-in element 200 effectively constrains the position of the corresponding plate 300 in the direction perpendicular to the corresponding axis and in the direction perpendicular to the corresponding connecting surface.

[0060] During disassembly, the first plate 310, the second plate 320, or the third plate 330 can be removed from the plug-in element 200 respectively, or the first plate 310, the second plate 320, or the third plate 330 can be removed from the connecting element 100 together with the plug-in element 200.

[0061] As an example, the first connecting surface 110 and the second connecting surface 120 are two intersecting surfaces parallel to the vertical direction 600, and the third connecting surface 130 is another intersecting surface perpendicular to the vertical direction 600 (for example, the third connecting surface 130 may be parallel to the horizontal plane). The first axis extends along the vertical direction 600, the second axis extends along the first horizontal direction 400, and the third axis extends along the second horizontal direction 500. The first groove 140 on the first connecting surface 110 extends along the first horizontal direction 400, and the second connecting surface 120... The first sink 140 extends along the vertical direction 600, and the first sink 140 on the third connecting surface 130 extends along the second horizontal direction 500. The first horizontal direction 400, the second horizontal direction 500 and the vertical direction 600 intersect. The first plate 310, the second plate 320 and the third plate 330 can be assembled along the first horizontal direction 400, the vertical direction 600 and the second horizontal direction 500 respectively. The plug-in element 200 effectively constrains the position of the corresponding plate 300 in the direction perpendicular to the corresponding connecting surface.

[0062] In some embodiments, where the connecting element 100 includes three connecting surfaces, the extension directions of the first recesses 140 on different connecting surfaces can also be other ways. For example, the first recesses 140 on two connecting surfaces are parallel to the same axis, and the first recesses 140 on another connecting surface are perpendicular to the axis. The three connecting surfaces can be defined as a first connecting surface 110, a second connecting surface 120, and a third connecting surface 130, respectively. The first connecting surface 110 and the second connecting surface 120 intersect at a first axis, the first connecting surface 110 and the third connecting surface 130 intersect at a second axis, and the second connecting surface 120 and the third connecting surface 130 intersect at a third axis. The first recesses 140 on the first connecting surface 110 and the second connecting surface 120 are parallel to the first axis and extend through the edge of the connecting element 100 away from the second axis to form a first opening 144, respectively. The first recess 140 on the third connecting surface 130 is perpendicular to the second axis. When the plug-in element 200 and the connecting element 100 are assembled, the first connecting portion 210 of the plug-in element 200 can be snapped into the corresponding first groove 140 from each first opening 144 in a direction parallel to the first axis and in a direction perpendicular to the second axis, respectively.

[0063] Correspondingly, the plate-type connecting assembly includes three intersecting plates 300, which can be defined as a first plate 310, a second plate 320, and a third plate 330, respectively. The first plate 310 has a plate surface parallel to the first connecting surface 110, the second plate 320 has a plate surface parallel to the second connecting surface 120, and the third plate 330 has a plate surface parallel to the third connecting surface 130. The plates of the first plate 310, the second plate 320, and the third plate 330 are each provided with a second recess 340 whose extension direction is consistent with the first recess 140 on the corresponding connecting surface. When the plate 300 is assembled with the plug-in element 200, the second connecting portion 220 of the plug-in element 200 can be engaged with the corresponding second recess 340 from each second opening 345 in a direction parallel to the first axis and a direction perpendicular to the second axis.

[0064] During assembly, firstly, insert the plug-in element 200 onto the first connecting surface 110, the second connecting surface 120, and the third connecting surface 130 to form exposed second connecting portions 220. Then, align the second opening 345 on the third plate 330 with the second connecting portion 220 on the third connecting surface 130, and push the third plate 330 along the extending direction of the second countersunk groove 340. Next, align the second opening 345 on the first plate 310 with the second connecting portion 220 on the first connecting surface 110, and push the first plate 310 along the extending direction of the second countersunk groove 340 on the first plate 310. Finally, align the second opening 345 on the second plate 320 with the second connecting portion 220 on the second connecting surface 120. The connecting part 220 pushes the second plate 320 along the extension direction of the second recess 340 on the second plate 320, so that the second recess 340 on the first plate 310, the second plate 320 and the third plate 330 can be engaged with the second connecting part 220. After engagement, the first plate 310, the second plate 320 and the third plate 330 intersect at their ends. The plate surfaces of the first plate 310, the second plate 320 and the third plate 330 abut against the first connecting surface 110, the second connecting surface 120 and the third connecting surface 130 respectively. Each plug-in element 200 effectively constrains the position of the corresponding plate 300 in the direction perpendicular to the corresponding axis and in the direction perpendicular to the corresponding connecting surface.

[0065] During disassembly, the first plate 310, the second plate 320, or the third plate 330 can be removed from the plug-in element 200 respectively, or the first plate 310, the second plate 320, or the third plate 330 can be removed from the connecting element 100 together with the plug-in element 200.

[0066] As an example, the first connecting surface 110 and the second connecting surface 120 are two intersecting surfaces parallel to the vertical direction 600, and the third connecting surface 130 is another intersecting surface perpendicular to the vertical direction 600 (for example, the third connecting surface 130 may be parallel to the horizontal plane). The first axis extends along the vertical direction 600, the second axis extends along the first horizontal direction 400, and the third axis extends along the second horizontal direction 500. The first groove 140 on the first connecting surface 110 extends along the vertical direction 600, the first groove 140 on the second connecting surface 120 extends along the vertical direction 600, and the first groove 140 on the third connecting surface 130 extends along the second horizontal direction 500. The second horizontal direction 500 intersects with the vertical direction 600. The first plate 310, the second plate 320, and the third plate 330 can be assembled along the vertical direction 600 and the second horizontal direction 500, respectively. The plug-in element 200 effectively constrains the position of the corresponding plate 300 in a direction perpendicular to the corresponding connecting surface.

[0067] In practical applications, the two intersecting plates 300 can be such that one of them intersects at one end of the other plate 300, forming a connecting angle. The connecting device is set inside the connecting angle to connect the two plates 300 together. Alternatively, one end of one of the two plates 300 can abut against any position in the middle of the surface of the other plate 300. In this case, the two plates 300 form two connecting angles, and a connecting device can be set in each of the two connecting angles to connect the two plates 300. The two scenarios apply to different panel 300 assembly structures in furniture. For example, when used to connect two outer side panels or outer frames in furniture, the two panels constituting the outer side panel intersect at their ends to form the outer wall or outer frame of the furniture. A connecting angle is formed on the inner side of the two panels 300, and they are connected and fixed by a connecting device. When used to connect a partition and a side panel in furniture, one end of the partition panel 300 abuts against one side panel of the side panel 300, forming two connecting angles. The partition and the side panel can be connected and fixed by a connecting device in each connecting angle.

[0068] In a specific application, the third plate 330 can be laid flat as a bottom or top plate, connecting the first plate 310, the second plate 320, and the third plate 330 respectively via a connecting device. First, the plug-in element 200 is inserted into the second recesses 340 on the first plate 310, the second plate 320, and the third plate 330, forming an exposed first connecting portion 210. Then, the first opening 144 on the third connecting surface 130 is aligned with the first connecting portion 210 on the third plate 330, and the first recess is... The connecting element 100 is pushed along the extension direction of the groove, and the first connecting portion 210 on the first plate 310 is aligned with the first opening 144 on the first connecting surface 110. The first plate 310 is pushed along the extension direction of the first groove 140 on the first connecting surface 110. The first connecting portion 210 on the second plate 320 is aligned with the first opening 144 on the second connecting surface 120. The second plate 320 is pushed along the extension direction of the first groove 140 on the second connecting surface 110 to complete the assembly.

[0069] The third plate 330 can be a polygonal plate, such as a triangular plate, a quadrilateral plate, a pentagonal plate, or a hexagonal plate. It is understood that two adjacent sides of a polygonal plate intersect to form a corner. Therefore, multiple sides of a polygonal plate intersect in pairs to form a number of corners equal to the number of sides. A second recess 340 can be provided at each corner of the third plate 330. Two intersecting plates 300 are assembled at the two sides of the third plate 330 that intersect at the same corner, thus defining a connection angle with the third plate 330 at the corner. The connecting element 100 connects to the corresponding plate 300 within each connection angle via a plug-in element 200. Thus, at each corner of the third plate 330, a structure is formed in which the third plate 330 and two plates 300 (such as the first plate 310 and the second plate 320) are fixed by a connecting device.

[0070] As an example, the third plate 330 can be a triangular plate. The number of corners formed by the third plate 330, the first plate 310, and the second plate 320 can be three. Each of the three corners can be provided with a second recess 340. In this scheme, the included angle between the two intersecting plates (the first plate 310 and the second plate 320) can be an acute angle. The first plate 310 and the second plate 320 also have a second recess 340 on the side facing the connecting element 100. During assembly, the plug-in element 200 is first installed in the four second recesses 340 of the third plate 330. The connecting element 100 is then installed on each plug-in element 200. Subsequently, the first plate 310 and the second plate 320 equipped with the plug-in element 200 are assembled onto the connecting element 100 to complete the assembly.

[0071] As another example, the third plate 330 can be a quadrilateral plate, such as a rectangular plate. The third plate 330 can be a rectangular plate, and the four corners of the third plate 330 can be provided with a second recess 340. The first plate 310 and the second plate 320 are provided with second recesses 340 on both sides. In this way, they can be assembled according to the assembly sequence in the example where the third plate 330 is a triangular plate. Two first plates 310 and two second plates 320 are assembled around the third plate 330.

[0072] As another example, the third plate 330 can also be a pentagonal plate, a hexagonal plate, or a polygonal plate with more sides. Correspondingly, the number of corners can be five, six, or more. Taking the scheme with five corners as an example, each of the five corners can be provided with a second recess 340. In this scheme, the included angle between the two intersecting plates (the first plate 310 and the second plate 320) can be an obtuse angle. The first plate 310 and the second plate 320 are also provided with a second recess 340 on the side facing the connecting element 100. During assembly, the plug-in element 200 is first installed in the five second recesses 340 of the third plate 330. The connecting element 100 is then installed on each plug-in element 200. Subsequently, the first plate 310 and the second plate 320 equipped with the plug-in element 200 are assembled onto the connecting element 100 to complete the assembly.

[0073] In a scheme where the connecting element 100 includes three connecting surfaces, the connecting device can be used for the mating connection of three plates 300, or for connecting two plates 300. When the connecting device is only used to connect two plates 300, any two intersecting connecting surfaces on the connecting element 100 can be mated with the plug-in element 200 and snap-fitted together with the two plates 300. The remaining connecting surface of the connecting element 100 may not be connected to the plug-in element 200, and can be used as a reinforcing structure between the two connecting surfaces used to connect the plates 300.

[0074] In some embodiments, the two intersecting connecting surfaces can be perpendicular to each other, or the included angle between the two intersecting connecting surfaces can be an obtuse angle or an acute angle, respectively used to connect two or three plates 300 with an acute angle, or to connect two or three plates 300 with an obtuse angle, so as to be suitable for some custom furniture with special angle corners.

[0075] In some embodiments, two first recesses 140 on the connecting element 100 that are perpendicular to the same axis can extend to the same position on the axis, i.e., the two first recesses 140 are connected to each other, or they can be located at different positions on the same axis, with the two first recesses 140 being staggered to accommodate different mounting positions on different plates 300.

[0076] This embodiment of the application achieves convenient assembly and disassembly of intersecting plates 300 through a first recess 140 on the connecting element 100, a plug-in element 200, and a second recess 340 on the plate 300. Please refer to... Figures 5 to 7As shown, in some embodiments, the first settling tank 140 includes a first opening 141, a first bottom wall 142, and a first side wall 143. The first opening 141 and the first bottom wall 142 are spaced apart and opposite to each other. The first side wall 143 extends from the first opening 141 to the first bottom wall 142. The distance D6 between the two first side walls 143 at the first opening 141 is less than the distance D7 between the two first side walls 143 at the first bottom wall 142. The first settling tank 140 can be configured as a trapezoidal structure that expands from the first opening 141 along the depth direction.

[0077] Correspondingly, the first connecting portion 210 of the plug-in element 200 may include a first top wall 211 and a second side wall 212. The second side wall 212 extends from the connection between the first connecting portion 210 and the second connecting portion 220 to the first top wall 211. The distance D3 between the two second side walls 212 at the connection with the second connecting portion 220 is smaller than the distance D1 between the two second side walls 212 at the first top wall 211. The first connecting portion 210 is used to be assembled in the first sink 140. The first sink 140 effectively constrains the first connecting portion 210 in a direction perpendicular to the bottom wall 142 of the first sink.

[0078] Please see Figures 5 to 7 As shown, in some embodiments, the second connecting portion 220 includes a second top wall 221 and a fourth side wall 222. The fourth side wall 222 extends from the connection between the second connecting portion 220 and the first connecting portion 210 to the second top wall 221. The distance D3 between the two fourth side walls 222 at the connection with the first connecting portion 210 is smaller than the distance D2 between the two fourth side walls 222 at the second top wall 221.

[0079] Correspondingly, the second settling tank 340 includes a second slot 341, a second bottom wall 342, and a third side wall 343. The second slot 341 and the second bottom wall 342 are spaced apart and opposite to each other. The third side wall 343 extends from the second slot 341 to the second bottom wall 342. The distance D4 between the two third side walls 343 at the second slot 341 is less than the distance D5 between the two third side walls 343 at the second bottom wall 342. The second settling tank 340 effectively constrains the second connecting portion 220 in the direction perpendicular to the second bottom wall 342.

[0080] Please see Figure 6As shown, in some embodiments, the thickness H1 of the first connecting portion 210 and the thickness H2 of the second connecting portion 220 can be set to the same size, and the distance D2 between the two fourth sidewalls 222 located at the second top wall 221 and the distance D1 between the two second sidewalls 212 located at the first top wall 211 can be set to the same size. Both the first connecting portion 210 and the second connecting portion 220 can be assembled and snapped into the first recess 140 or the second recess 340 for foolproof purposes. Alternatively, the thickness H1 of the first connecting portion 210 is smaller than the thickness H2 of the second connecting portion 220, thereby reducing the depth of the first recess 140 and thus reducing the overall size of the connecting element 100, which can reduce the space occupied by the connecting corner of the plate 300 after assembly. Alternatively, the thickness H1 of the first connecting portion 210 can be greater than the thickness H2 of the second connecting portion 220, thereby reducing the depth of the second groove 340 on the plate 300, thus improving the structural strength of the plate 300 itself and improving the stability of the overall assembly. On the other hand, the thinner second connecting portion 220 can be used when the plate 300 is thinner, so that the plate 300 has sufficient thickness at the second groove 340 position to ensure the strength of the connection position.

[0081] Please see Figure 8 and Figure 9 As shown, in some embodiments, the plate 300 includes a plate body and a connecting seat 360. The plate bodies of intersecting plates 300 intersect and define a connecting angle at the intersection. A third recess 350 is provided on the side of the plate body facing the connecting element 100, corresponding to the position of the first recess 140. The connecting seat 360 is disposed in the third recess 350 and connected to the plate body. A second recess 340 is disposed on the side of the connecting seat 360 facing the connecting element 100. By assembling a connecting seat 360 with a second recess 340 in the third recess 350, the second connecting part 220 is stably assembled with the plate 300 through the connecting seat 360. Glue or other adhesive substances can be laid in the third recess 350 to improve the stability of the assembly, thereby realizing the assembly of the plate 300 and the second connecting part 220. The third sink 350 can be a rectangular sink, and the second connecting part 220 can be assembled with the plate 300 through the setting of the connecting seat 360. Alternatively, the third sink 350 can also be the same shape as the second sink 340, so as to reduce the damage to the plate 300 when friction or collision damage occurs at the connection between the second connecting part 220 and the connecting seat 360, and reassemble by replacing the connecting seat 360.

[0082] Please see Figure 5 and Figure 7 As shown, in some embodiments, the plate 300 may not have a connecting seat 360, and the second groove 340 may be directly formed on the plate body of the plate 300, and the second connecting part 220 may be directly connected to the plate body of the plate 300, which is beneficial to simplify the structure and reduce the number of parts.

[0083] The furniture according to this utility model embodiment includes a panel-type connecting assembly based on the second aspect embodiment of this utility model described above. Specifically, the furniture may be a table, a cabinet, or a bed, or other furniture product with a corner structure. When used as a table, the tabletop, side panels, and back panel can be constructed using the panel-type connecting assembly. When used as a cabinet, the cabinet's partitions, side panels, and top panel can be constructed using the panel-type connecting assembly. When used as a bed, the bed's base and two side panels can be constructed using the panel-type connecting assembly.

[0084] As an example, the table includes a first panel, a second panel, and a third panel, wherein the first panel can serve as the back panel of the table, the second panel can serve as one of the side panels of the table, and the third panel can serve as the tabletop. The first panel, the second panel, and the third panel are connected to the connecting element 100 at a corner of the table via a plug-in element 200, which is located inside the corner of the table.

[0085] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
