DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] In order to solve the problem that the connection parts of existing furniture are exposed, affecting the appearance, and the connection structure of the board may also affect the use of the board surface if it is exposed, please refer to Figure 1-Figure 6 , this embodiment provides the following technical solutions:

[0028] A modular furniture panel concealed connection structure includes a panel body 1 and a locking member 2 connected to the panel body 1, wherein two side walls of the panel body 1 are fixedly connected with a plug-in rod 11, and the other two side walls of the panel body 1 are provided with a plug-in hole 12 matching the plug-in rod 11, and adjacent panel bodies 1 are connected via the plug-in rod 11 and the plug-in hole 12. The connection method is simple, and the plug-in rod 11 after plugging is completely placed in the plug-in hole 12, so that the connection structure is completely hidden.

[0029] However, simply plugging the plug rod 11 into the plug hole 12 may cause the sheet body 1 to become loose and have poor structural strength. Therefore, a locking groove 13 is provided on the side wall of the sheet body 1 and a locking member 2 is installed to achieve a tight connection between the sheet bodies 1. The locking groove 13 is a flat right triangle structure. The locking member 2 is installed along the vertical side of the right triangle. After rotation, the locking member 2 is fixed to the hypotenuse of the locking groove 13 and locks the adjacent sheet body 1.

[0030] The locking member 2 includes a first pressure rod 21, a second pressure rod 22 and a connecting shaft 23, wherein one end of the first pressure rod 21 and the second pressure rod 22 are hingedly connected by the connecting shaft 23, wherein the first pressure rod 21 and the second pressure rod 22 have the same structure, and both the first pressure rod 21 and the second pressure rod 22 include a spring barrel 211, a positioning spring 212 and a telescopic rod 213, a positioning spring 212 is arranged in the spring barrel 211, both ends of the spring barrel 211 are sealed structures, and a guide hole 2111 is opened at one end of the spring barrel 211, and the telescopic rod 213 passes through the guide hole 2111, and the telescopic rod 213 is a double-rod structure, and a certain gap is left between the double rods, which improves the stability of the guide and prevents the spring barrel 211 from being pulled out of the locking groove 13 obliquely, and one end of the telescopic rod 213 placed in the spring barrel 211 is fixedly connected with a guide block 2131, and the guide block 2131 is movably connected to the inner wall of the spring tube 211, one end of the positioning spring 212 is fixedly connected to the guide block 2131, and the other end of the positioning spring 212 is fixedly connected to the bottom of the spring tube 211. Under the action of the positioning spring 212, the guide block 2131 is supported to move toward the top of the spring tube 211. In the absence of external force, the telescopic rod 213 extends out of the spring tube 213. At the same time, when the telescopic rod 213 is pushed, the telescopic rod 213 can be controlled to move to the inner position of the spring tube 211, squeezing the positioning spring 212. The squeezing of the telescopic rod 213 is mainly used to install the first pressure rod 21 and the second pressure rod 22. The end of the telescopic rod 213 placed outside the spring tube 211 is provided with a rotating hole 2132, and the rotating hole 2132 is sleeved with the connecting shaft 23. The telescopic rod 213 drives the spring tube 211 as a whole to rotate around the connecting shaft 23.

[0031] The notch position of the locking groove 13 is provided with a cylindrical socket 131, and the cylindrical socket 131 is used for inserting the spring barrel 211. Due to the limitation of the cylindrical socket 131, when the first pressure rod 21 and the second pressure rod 22 are installed, the spring barrel 211 is vertically inserted, and at the same time, positioning grooves 1311 matching the connecting shaft 23 are opened on both sides of the cylindrical socket 131. The positioning groove 1311 is a semi-cylindrical structure, and the connecting shaft 23 is integrally stuck in the two connected plate bodies 1. After the engagement, the connecting shaft 23 cannot move. A plug-in block 132 is provided on the side wall of the locking groove 13. The plug-in block 132 is arranged on the side of the locking groove 13 where the inclined wall is provided, and is used to limit the installation path of the spring barrel 211. At the same time, after the spring barrel 211 rotates, the gap between the double rods of the telescopic rod 213 is plugged into the plug-in block 132, and a wedge block 133 is provided at the bottom of the locking groove 13. The setting of the wedge block 133 can limit the spring barrel 21 One-way sliding prevents the spring barrel 211 from being displaced during use. One end of the wedge block 133 corresponding to the cylindrical socket 131 is provided with a pushing slope 1331. When the spring barrel 211 moves downward, it contacts the pushing slope 1331 and continuously pushes the spring barrel 211 to move into the locking groove 13. The pushing slope 1331 pushes the spring barrel 211 to move along the direction of the wedge block 133. The other end of the wedge block 133 is provided with a positioning slope 1332. When the spring barrel 211 is in contact with the inclined wall of the locking groove 13, the bottom of the spring barrel 211 is pressed against the positioning slope 1332. The spring barrel 211 and the telescopic rod 213 are extended to the maximum as a whole. The distance from the cylindrical socket 131 to the bottom of the groove is short and cannot meet the extension requirement of the spring barrel 211. Therefore, the spring barrel 211 cannot rotate in the reverse direction. In addition, the resistance of the wedge block 133 makes the spring barrel 211 not easily loose after installation, and the structure is more stable.

[0032] The locking member 2 is provided with a symmetrical first pressure rod 21 and a second pressure rod 22, which are respectively used to connect the two plate bodies 1. After the first pressure rod 21 and the second pressure rod 22 are fixed in position by the connecting shaft 23, the first pressure rod 21 and the second pressure rod 22 cannot move and can only rotate around the connecting shaft 23. Because of the force applied by the positioning spring 212, the telescopic rod 213 extends outward. In order to meet the need for the extension space of the telescopic rod 213, the spring tube 211 is tilted, and the first pressure rod 21 and the second pressure rod 22 form a certain angle, which applies pressure to the plate body 1 so that it cannot be separated.

[0033] In order to better demonstrate the connection process of the modular furniture panel hidden connection structure, this embodiment now proposes a connection method of the modular furniture panel hidden connection structure, including the following steps:

[0034] Step 1: Prepare the plate body 1 to be connected and the locking member 2 for connecting the plate body 1, sleeve the first pressure rod 21 and the second pressure rod 22 through the connecting shaft 23, insert the spring tubes 211 of the first pressure rod 21 and the second pressure rod 22 from the cylindrical sockets 131 corresponding to the two plate bodies 1 to be connected, and align the plug rod 11 with the plug hole 12;

[0035] Step 2: Push the two sheet bodies 1 closer to each other, the spring tube 211 is sent into the locking groove 13, and the spring tube 211 contacts the pushing slope 1331 and rotates. As the distance between the two sheet bodies 1 gets closer and closer, the spring tube 211 turns to the side wall close to the locking groove 13. At this time, the connecting shaft 23 is engaged with the positioning groove 1311 of one of the sheet bodies 1, and the other sheet body 1 is pushed closer to it until the plug-in rod 11 and the plug-in hole 12 are fully plugged in. The positioning groove 1311 of the other sheet body 1 wraps the connecting shaft 23. The two sheet bodies 1 are positioned by a clamping force applied by the positioning spring 212, which increases the friction between the plug-in rod 11 and the plug-in hole 12 to prevent the two sheet bodies 1 from separating.

[0036] Embodiment 2:

[0037] See also Figure 7 In this embodiment, an annular protrusion 2112 is provided on the outer wall of the spring tube 211, and an annular groove matching the annular protrusion 2112 is provided on the oblique side wall of the locking groove 13. The annular protrusion 2112 is engaged with the annular groove to increase the contact area between the spring tube 211 and the locking groove 13, thereby improving the clamping force of the spring tube 211 on the plate body 1 under the action of the positioning spring 212. The other structures are the same as those in the first embodiment.

[0038] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
