That is, the existing connectors usually include expansion bolts (rubber plugs / wooden plugs), eccentric parts, and three parts. The connection of panel furniture is achieved through the assembly of the above structure. This connection has the advantage of convenient assembly, but the disadvantages are also obvious. Since the tight connection is achieved by rotating the eccentric cap and pulling the connecting rod mounted on the eccentric cap to move, the connection force of this structure is not strong, the tightness is not high, and the bearing capacity is insufficient. After a long time, it is inevitable that it will loosen, which will lead to the loosening of the connection between the panels. In addition, furniture connected with this structure will leave eccentric holes on the surface of the furniture and affect the appearance of the product.

DETAILED DESCRIPTION

[0036] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments.

[0037] Embodiment 1:

[0038] like Figure 1-6 As shown, this embodiment provides a connecting member, including a first connecting mechanism 1, a second connecting mechanism 2 and a plurality of countersunk screws 3.

[0039] like Figure 1-4 As shown, the first connecting mechanism 1 includes an upper surface 101 and a lower surface 102 arranged opposite to the upper surface 101. The upper surface 101 faces the second connecting mechanism 2 and contacts at least part of the surface of the second connecting mechanism 2. The first connecting mechanism 1 is provided with a plug hole 11 that passes through the upper surface 101 and the lower surface 102, and a slide groove 12 that is connected to the plug hole 11. The inner diameter of the plug hole 11 is greater than the width of the slide groove 12. It should be noted that the width of the slide groove 12 mentioned here refers to the distance between the two inner walls arranged along the long axis direction of the slide groove 12. In other words, along the Figure 2 In the direction of YY, the inner diameter of the insertion hole is larger than the inner diameter of the slide groove 12. By assembling with the second connecting mechanism 2, the connection piece can be engaged and fixed.

[0040] like Figure 3 , 4As shown, transition structures 13 are provided on both sides of the slide groove 12, which are recessed and extend from the lower surface 102 toward the insertion hole. Specifically, in this embodiment, the transition structure 13 is a U-shaped groove slope surrounding the slide groove 12. The transition structure 13 includes two inclined surfaces symmetrically arranged on both sides of the slide groove 12, one end of the inclined surface is connected to the lower surface 102, and the other end extends into the insertion hole 11. Such a structure will play a guiding role when the second connection mechanism is assembled, and it is convenient to assemble.

[0041] Furthermore, at least one first fixing hole 14 is provided on the first connecting mechanism 1, and the countersunk screw 3 is inserted into the first fixing hole 14 to realize the installation and fixation of the first connecting mechanism 1. Specifically, in the present embodiment, there are two first fixing holes 14, which are respectively located at the two ends of the first connecting mechanism 1 and in the extension direction of the slide groove 12. The extension direction of the slide groove mentioned here refers to the long axis direction of the slide groove 12. In this way, it can be ensured that both sides of the first connecting mechanism 1 are evenly stressed, not easy to fall off or be damaged, and the product reliability is high. Further, as Figure 3 As shown, the first fixing hole 14 is a prism-shaped hole. Specifically, the diameter of the first fixing hole 14 on the lower surface 102 is smaller than the diameter on the upper surface 101. From the upper surface 101 to the lower surface 102, the hole diameter of the first fixing hole 14 gradually decreases, so that the countersunk screw 3 is tightened and the firmness of the assembly is improved. Specifically, in this embodiment, the minimum inner diameter of the first fixing hole 14 is 5 mm.

[0042] In this embodiment, the countersunk screw 3 is preferably a wood screw, which makes the board connection more solid and has high reliability.

[0043] like Figure 5 , 6 As shown, the second connection mechanism 2 includes a main body 21 , a locking structure 22 protruding and extending from the main body 21 , and a spring bolt positioning structure 23 .

[0044] After assembly, the main body 21 is attached to the upper surface of the first connecting mechanism 1. Specifically, in this embodiment, the locking structure 22 is a mushroom bolt head connection, including a head 221 matching the socket 11 and a connecting portion 222 connecting the head 221 and the main body 21. The diameter of the head 221 is greater than the width of the slide groove 12 and less than or equal to the inner diameter of the socket 11. Such a structure allows the head 221 to pass through the socket 11 and slide along the long axis direction of the slide groove 12 under the guidance of the transition structure 13. Figure 6As shown, a conical head 231 is provided on the side of the spring bolt positioning structure 23 close to the first connecting mechanism 1, and a return spring 232 is provided on the side away from the first connecting mechanism 1. The return spring is squeezed by force so that the second connecting mechanism 2 is pressed toward the first connecting mechanism 1. Specifically, during the assembly process, when the head 221 slides to the end of the slide groove 12 away from the socket 11, the return spring 232 of the spring bolt positioning structure 23 pushes the conical head 231 to be inserted into the socket 11, so as to realize the assembly of the first connecting mechanism 1 and the second connecting mechanism 2.

[0045] Similar to the first connecting mechanism 1, further, the second connecting mechanism 2 is also provided with at least one second fixing hole 24, and the countersunk screw 3 is inserted into the second fixing hole 24 to realize the installation and fixation of the second connecting mechanism 2. Specifically, in the present embodiment, there are two second fixing holes 24, which are respectively located on both sides of the locking structure 22. The spring bolt positioning structure 23 is arranged at one end of the second connecting mechanism 2 to facilitate the locking of the spring bolt positioning structure 23 with the socket 11. That is, the two second fixing holes and the locking structure 22 and the spring bolt positioning structure 23 are arranged in sequence. In this way, the second connecting mechanism 2 can be guaranteed to be uniformly stressed, not easy to fall off or be damaged, and the product reliability is high. Further, as Figure 6 As shown, the second fixing hole 24 is a prism-shaped hole. Specifically, the diameter of the second fixing hole 24 on the side surface away from the first connecting mechanism 1 is smaller than the diameter on the side surface close to the first connecting mechanism 1, that is, the second fixing hole 24 gradually decreases in the direction away from the first connecting mechanism 1, so that it plays a role in tightening the countersunk screw 3 and improves the firmness of the assembly. Specifically, in this embodiment, the minimum inner diameter of the second fixing hole 24 is 5mm.

[0046] Specifically, in this embodiment, there are four countersunk screws 3, which are respectively matched with the two first fixing holes 14 and the two second fixing holes 24. Of course, the protection scope of the present invention is not limited thereto. In fact, the number and position of the countersunk screws 3 can be adjusted according to actual needs. In other optional embodiments, the assembly method of the connector can also be changed, such as by gluing or welding.

[0047] Example 2

[0048] like Figure 7 As shown, the second embodiment of the present invention is an improvement made on the basis of the first embodiment. It is substantially the same as the first embodiment, a connecting member including a first connecting mechanism 1', a second connecting mechanism and a plurality of countersunk screws.

[0049] like Figure 1-4As shown, the first connecting mechanism 1' includes an upper surface and a lower surface arranged opposite to the upper surface. The upper surface faces the second connecting mechanism and contacts at least part of the surface of the second connecting mechanism. The first connecting mechanism 1' is provided with a plug hole 11' that passes through the upper surface and the lower surface, and a slide groove 12' that is connected to the plug hole 11'. The inner diameter of the plug hole 11' is greater than the width of the slide groove 12'. It should be noted that the width of the slide groove 12 mentioned here refers to the distance between the two inner walls arranged along the long axis direction of the slide groove 12. In other words, along Figure 2 In the direction of YY, the inner diameter of the insertion hole 11' is larger than the inner diameter of the sliding groove 12'. By combining with the second connecting mechanism, the connection piece can be engaged and fixed.

[0050] The two sides of the slide groove 12' are provided with transition structures that are recessed and extend from the lower surface toward the insertion hole '. Specifically, in this embodiment, the transition structure is a U-shaped groove slope surrounding the slide groove 12'. The transition structure includes two inclined surfaces symmetrically arranged on both sides of the slide groove 12', one end of the inclined surface is connected to the lower surface, and the other end extends into the insertion hole 11'. Such a structure will play a guiding role when the second connection mechanism is assembled, and it is convenient to assemble.

[0051] Furthermore, at least one first fixing hole 14' is provided on the first connecting mechanism 1', and a countersunk screw is inserted into the first fixing hole 14' to realize the installation and fixation of the first connecting mechanism 1'. Specifically, in this embodiment, there are two first fixing holes 14', which are respectively located at the two ends of the first connecting mechanism 1' and are located in the extension direction of the slide 12'. The extension direction of the slide 12' mentioned here refers to the long axis direction of the slide 12'. In this way, it can be ensured that both sides of the first connecting mechanism 1' are evenly stressed, not easy to fall off or damage, and the product reliability is high. The first fixing hole 14' is a prism-shaped hole. Specifically, the diameter of the first fixing hole 14' on the lower surface is smaller than the diameter on the upper surface. From the upper surface to the lower surface, the aperture of the first fixing hole 14' gradually decreases, so that it plays a role in tightening the countersunk screw and improves the firmness of the assembly. Specifically, in this embodiment, the minimum inner diameter of the first fixing hole 14' is 5mm.

[0052] Different from the first embodiment, in this embodiment, the first connecting mechanism 1' includes a slot portion and fixed ends 15' that are bent and extended from both sides of the slot portion in a direction away from the upper surface, the socket 11' and the slide 12' are located on the slot portion, and the first fixing hole 14' is located on the two fixed ends 15'. The structure of the slot portion is equivalent to the structure of the first connecting mechanism 1 in the first embodiment. This embodiment is equivalent to bending and extending on the basis of the first embodiment to form two fixed ends 15', and the first fixing hole 14' is arranged on the fixed ends 15'. The function of the fixed end 15' is to give the first connecting mechanism 1' a processing and installation margin, and to give the slide 12' and the slot 11' a avoidance space to facilitate the assembly between the first connecting mechanism 1' and the second connecting mechanism.

[0053] The second connection mechanism of this embodiment has the same structure as that of the first embodiment. The second connection mechanism 2 includes a main body 21 , a locking structure 22 protruding and extending from the main body 21 , and a spring bolt positioning structure 23 .

[0054] After the assembly is completed, the main body 21 is attached to the upper surface of the first connecting mechanism 1'. Specifically, in this embodiment, the locking structure 22 is a mushroom bolt head connection, including a head 221 matching the socket 11' and a connecting portion 222 connecting the head 221 and the main body 21. The diameter of the head 221 is greater than the width of the slide groove 12' and less than or equal to the inner diameter of the socket 11'. Such a structure allows the head 221 to pass through the socket 11' and slide along the long axis direction of the slide groove 12' under the guidance of the transition structure. A conical head 231 is provided on the side of the spring bolt positioning structure 23 close to the first connecting mechanism 1', and a return spring 232 is provided on the side away from the first connecting mechanism 1'. The return spring is squeezed by force to press the second connecting mechanism 2 toward the first connecting mechanism 1'. Specifically, during the assembly process, when the head 221 slides to the end of the slide groove 12' away from the socket 11', the return spring 232 of the spring bolt positioning structure 23 pushes the conical head 231 to be inserted into the socket 11', so as to realize the assembly of the first connecting mechanism 1' and the second connecting mechanism 2.

[0055] Similar to the first connecting mechanism 1', further, at least one second fixing hole 24 is provided on the second connecting mechanism 2, and the countersunk screw 3 is inserted into the second fixing hole 24, which is used to realize the installation and fixation of the second connecting mechanism 2. Specifically, in this embodiment, there are two second fixing holes 24, which are respectively located on both sides of the locking structure 22. The spring bolt positioning structure 23 is arranged at one end of the second connecting mechanism 2, so as to realize the locking of the spring bolt positioning structure 23 and the jack 11. That is, the two second fixing holes and the locking structure 22 and the spring bolt positioning structure 23 are arranged in sequence. In this way, the uniform force of the second connecting mechanism 2 can be guaranteed, and it is not easy to fall off or be damaged, and the product reliability is high. The second fixing hole 24 is a prism-shaped hole. Specifically, the diameter of the second fixing hole 24 on the side surface away from the first connecting mechanism 1' is smaller than the diameter on the side surface close to the first connecting mechanism 1', that is, the second fixing hole 24 is in the direction away from the first connecting mechanism 1', and the aperture gradually decreases, so that the countersunk screw 3 is tightened and the firmness of the assembly is improved. Specifically, in this embodiment, the minimum inner diameter of the second fixing hole 24 is 5 mm.

[0056] Specifically, in this embodiment, there are four countersunk screws 3, which are respectively matched with the two first fixing holes 14 and the two second fixing holes 24. Of course, the protection scope of the present invention is not limited thereto. In fact, the number and position of the countersunk screws 3 can be adjusted according to actual needs. In other optional embodiments, the assembly method of the connector can also be changed, such as by gluing or welding.

[0057] In other optional embodiments, the second connecting mechanism may also be provided with a fixed end, and the principle is the same.

[0058] like Figure 8-13 As shown, the present invention also provides a panel furniture connection structure, which adopts the connection piece as described above, and further includes a first connection plate 4 and a second connection plate 5.

[0059] like Fig. 9 As shown, in the first embodiment, the first connecting plate 4 is provided with a first recessed groove along its length direction, and the second connecting plate is provided with a second recessed groove 51 along its thickness direction. The first connecting mechanism 1 is installed in the first recessed groove, and the second connecting mechanism 2 is installed in the second recessed groove 51. In this embodiment, the first connecting mechanism 1 is flush with the surface of the first connecting plate 4, which has the advantage of beautiful appearance. Furthermore, a positioning countersunk hole 52 is also provided in the second recessed groove 51, and during the matching assembly process, the spring bolt positioning structure 23 on the second connecting mechanism 2 matches the spring bolt positioning structure and the positioning countersunk hole.

[0060] like Fig.10As shown, in the second embodiment, the first connecting plate 4 is provided with a plurality of mounting screw holes matching with the countersunk screws along its length direction, and the second connecting plate is provided with a second countersunk groove 51 along its thickness direction. The first connecting mechanism 1 is tightened and fixed to the first connecting plate by the countersunk screws 3 and the mounting screw holes. At this time, the first connecting mechanism protrudes from the surface of the first connecting plate 4, giving the first connecting mechanism 1' a processing and installation margin, and giving the slide groove 12' and the socket 11' a space to avoid to facilitate the assembly between the first connecting mechanism 1' and the second connecting mechanism. Similar to the first embodiment, the second connecting mechanism 2 is installed in the second countersunk groove 51. Furthermore, a positioning countersunk hole 52 is also provided in the second countersunk groove 51. During the matching assembly process, the spring bolt positioning structure 23 on the second connecting mechanism 2 matches the spring bolt positioning structure and the positioning countersunk hole.

[0061] like Fig.13 As shown, the present invention also provides a panel furniture assembly method, which adopts the panel furniture connection structure as described above, and comprises the following steps:

[0062] Install the first connecting mechanism in the first recessed groove and tighten it with countersunk screws;

[0063] Install the second connecting mechanism in the second sink groove, match the spring bolt positioning structure with the positioning sink hole, and lock and fix them with countersunk screws;

[0064] The first connecting plate and the second connecting plate are arranged alternately in the height direction so that the locking structure is inserted into the insertion hole;

[0065] The second connecting plate is pushed downward in the height direction, so that the locking structure moves downward along the slide groove, and the spring bolt positioning structure is inserted into the insertion hole to complete the assembly of the panel furniture.

[0066] The present invention realizes the assembly of panel furniture by cooperating the locking structure with the socket and the slide groove, replacing the prior art method of realizing the coordination of three parts including expansion bolts, bolts and eccentric parts. It not only has a simple structure, but also is not easy to slip, has stronger connection force and higher reliability. The connection structure formed by the connecting piece of the present invention can be completely hidden, beautiful and generous, and can be disassembled multiple times and repeatedly installed and reused, thus providing a good user experience.

[0067] The present invention is not limited to the above optional implementations, and anyone can derive other various forms of products under the enlightenment of the present invention. The above specific implementations should not be understood as limiting the scope of protection of the present invention. The scope of protection of the present invention should be based on the definition in the claims, and the description can be used to interpret the claims.
