DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] Reference Figures 1 to 7 As shown, an embodiment of the utility model provides a connecting piece.

[0030] The connector comprises: a connector body 1; a first connecting portion 2, located on one side of the connector body 1, and used to directly or indirectly connect to one of at least two items to be connected together; a second connecting portion 3, located on the other side of the connector body 1, and used to connect to a second connecting groove 51 of the other of the at least two items to be connected together; the second connecting groove 51 has a second main groove 511, a second neck 512 located on the opening side of the second main groove 511, and a second shoulder 513 located at the junction of the second main groove 511 and the second neck 512; a wing portion 31 is provided on the second connecting portion 3, which is suitable for abutting against the second shoulder 513 when the second connecting portion 3 is embedded in the second connecting groove 51 to achieve the connection between the second connecting portion 3 and the second connecting groove 51, and the second connecting portion 3 and the second connecting groove 51 are slidably matched in their extending direction; a first groove 11 (such as Figures 2 to 3 shown).

[0031] In the process of the connector realizing the connection of the two objects to be connected, especially in the process of the second connection part 3 being installed in the second connection groove 51, it is necessary to cooperate with the sliding step of the second connection part 3 in the extension direction of the second connection groove 51. In the sliding process of the second connection part 3, there may be tiny dust and other granular impurities in the second connection groove 51 (for example, the inner wall of the processed second connection groove may have burrs), which will block the sliding of the second connection part 3 and cause sliding difficulty. In some practical applications, when the two objects to be connected are made of wood, due to the characteristics of the wood itself, the inner wall of the processed second connection groove 51 may have burrs, especially at the angular position, which may affect the relative sliding of the second connection part 3 and the second connection groove 51. For this reason, by opening a first groove 11 at the junction of the connector body 1 and the second connection part 3, corresponding to the position of the second shoulder 513, when the second connection part 3 slides in the second connection groove 51, it can collect or store the wood chips, dust, burrs and other granular impurities generated, so as to ensure the smooth sliding of the second connection part 3 in the second connection groove 51.

[0032] As a preferred implementation of this embodiment, the connector body 1 is provided with a second groove 12 (such as Figure 2 and Figure 6 ), when the connector connects the two items together, the second groove 12 corresponds to the joint of the two items. After the two items are connected by the connector, there will be two connection situations, such as the connection surfaces of the two items are in contact or there is a gap. If the opening of the second connection groove 51 of the connected items is accidentally caused to have burrs, or slight deformation or bulges during the processing, transportation or assembly process of the connected items, the second groove can provide a certain avoidance space for the burrs, bulges, etc. at the opening of the second connection groove when the two connected items are assembled by the connector, so as to ensure the smoothness of the connection of the two items by the connector, and avoid the situation that the two connected items cannot be installed in place or jammed during the assembly process.

[0033] Specifically, the second connecting groove 51 is a T-shaped groove (such as Figure 3 As shown in the figure, the second connecting portion 3 is embedded in the T-slot and slidably cooperates with the T-slot in the extension direction of the T-slot, that is, the second main groove 511, the second neck 512 and the second shoulder 513 of the second connecting groove 51 are combined to form a T-shaped groove body, and the second shoulder 513 and the second neck 512 are used to limit the wing 31 of the second connecting portion 3 to avoid separation of the second connecting portion 3 after being connected to the second connecting groove 51.

[0034] In some practical applications, the T-slot may have at least two shapes:

[0035] First, one end of the T-slot can penetrate the other of the at least two objects along its extension direction, so that when the second connecting part 3 is inserted into the T-slot, it is inserted or slid into the end of the T-slot, and when the second connecting part 3 slides in the T-slot until it contacts the other end of the T-slot, the connecting piece is installed in place;

[0036] In the actual assembly process, the first connection part 2 of the connector is first installed on one of the two objects, and then the second connection part 3 is installed in the T-slot of the other object. When the second connection part 3 abuts against the end of the T-slot, the two connected objects are installed in place, ensuring the relative positions of the two connected objects. In addition, in this case, during the sliding process of the second connection part 3, its wing part 31 is always limited by the second neck part 512 and the second shoulder part 513 of the T-slot, ensuring that the two connected objects fit together or maintain a set gap.

[0037] Secondly, the T-shaped slot is provided with a second notch 514 (such as Figure 4 , 5 In this case, one or more T-slots of the aforementioned structure can be provided according to the size of the other of the two objects, and the second connecting portion 3 is inserted in a direction perpendicular to the connecting surface of the object and completely abuts against the T-slot. During the insertion process, the wing 31 at the side end of the second connecting portion 3 enters the T-slot from the second notch 514, and then the connecting piece slides in the T-slot, so that the wing 31 of the second connecting portion 3 abuts against the second shoulder 513, thereby realizing the connection between the connecting piece and the connected object;

[0038] In the actual assembly process, the first connecting part 2 of the connecting piece is first installed on one of the two objects, and then the second connecting part 3 is installed in the T-slot of the other object, and the relative sliding between the T-slot and the connecting piece is coordinated so that the second connecting part 3 abuts against the end of the T-slot and the wing 31 abuts against the wall of the second shoulder 513. The connecting piece is then installed in place and the relative positions of the two connected objects are guaranteed.

[0039] Further, one of the at least two objects has a first connecting groove 41, and the first connecting groove 41 has a first main groove 411, a first neck portion 412 located at the opening side of the first main groove 411, and a first shoulder portion 413 located at the junction of the first main groove 411 and the first neck portion 412;

[0040] In practical applications, the shape of the first connecting groove 41 can adopt any shape of the second connecting groove 51 mentioned above. The two connected items have at least four combination methods under the combination of different shapes of the corresponding first connecting groove or the second connecting groove. After actual testing, it is best for the first connecting groove and the second connecting groove to adopt the second shape of the T-slot mentioned above. While achieving the connection of the two items, the strength of the grooves of the two items (that is, the first connecting groove or the second connecting groove) can be guaranteed.

[0041] In addition, when the first connecting groove 41 and the second connecting groove 51 adopt the same shape, this configuration can facilitate the unified processing of the objects to be connected and save costs.

[0042] Specifically, the first connecting part 2 has a supporting part 21, one end of which is connected to the connecting piece body 1, and the other end is connected to a pair of elastic arms 22 with free ends suspended in the air, which are suitable for abutting against the first shoulder 413 when the first connecting part 2 is embedded in the first connecting groove 41 to achieve the connection between the first connecting part 2 and the first connecting groove 41.

[0043] In this embodiment, the first connecting portion 2 is also embedded in the first connecting groove 41. When the elastic arm 22 first contacts the first neck 412, it is squeezed by the first neck 412 and elastically deformed inward. When the elastic arm 22 is completely separated from the first neck 412, the support portion 21 also abuts against the inner bottom of the first connecting groove 41, and the elastic arm 22 is elastically reset, so that the end of the elastic arm 22 is stretched open and abuts against the first shoulder 413, thereby realizing the connection between the first connecting portion 2 and the first connecting groove 41. The elastic arm 22 is deformed to achieve the placement of the connecting member in the first connecting groove 41, thereby stabilizing the connection between the first connecting member and the connected object.

[0044] In addition, the first connecting groove 41 also has first notches 414 (such as Figure 5 As shown in the figure, the structure of the second notch 514 on the second connecting groove is consistent with that of the first connecting portion 2, and the corresponding first connecting portion 2 is also provided with circular limiting portions 23 at both ends in the length direction. After the first connecting member is completely installed in the first connecting groove 41, the two circular limiting portions are just embedded in the two circular limiting portions to ensure the connection stability between the connecting member and the first connecting groove 41.

[0045] Furthermore, linear grooves 13 are provided on one side of the connector body 1 close to the first connecting portion 2 and on both sides of the supporting portion 21 .

[0046] A connection structure, reference Figures 1 to 5 As shown:

[0047] The connection structure comprises: a first connection object 4; a second connection object 5 having a second connection groove 51, wherein the second connection groove 51 has a second main groove 511, a second neck portion 512 located at the opening side of the second main groove 511, and a second shoulder portion 513 located at the junction of the second main groove 511 and the second neck portion 512;

[0048] The connector comprises a connector body 1, a first connecting portion 2 located at one side of the connector body 1 and suitable for being directly or indirectly connected to a first connecting object 4, and a second connecting portion 3 located at the other side of the connector body 1 and suitable for being connected to a second connecting groove 51;

[0049] The second connecting portion 3 is provided with a wing portion 31, which is suitable for abutting against the second shoulder portion 513 to achieve the connection between the second connecting portion 3 and the second connecting groove 51 when the second connecting portion 3 is embedded in the second connecting groove 51; a first groove 11 is opened at the junction of the connecting member body 1 and the second connecting portion 3, corresponding to the position of the second shoulder portion 513.

[0050] Furthermore, the connector body 1 is provided with a second groove 12. When the connector connects the first connected article 4 and the second connected article 5 together, the second groove 12 corresponds to the seam of the two articles.

[0051] Specifically, the second connecting groove 51 is a T-shaped groove, and the second connecting portion 3 is embedded in the T-shaped groove and slidably cooperates with the T-shaped groove in the extending direction of the T-shaped groove.

[0052] Specifically, the first connecting article 4 has a first connecting groove 41 , which has a first main groove 411 , a first neck 412 located at the opening side of the first main groove 411 , and a first shoulder 413 located at the junction of the first main groove 411 and the first neck 412 .

[0053] Specifically, the first connecting part 2 has a supporting part 21, one end of which is connected to the connecting piece body 1, and the other end is connected to a pair of elastic arms 22 with free ends suspended in the air, which are suitable for abutting against the first shoulder 413 when the first connecting part 2 is embedded in the first connecting groove 41 to achieve the connection between the first connecting part 2 and the first connecting groove 41.

[0054] In some practical applications, the first connecting object 4 of the connecting structure is a wooden board, and the second connecting object 5 is also a wooden board. The connecting member is used to realize the assembly of two wooden boards at various angles.

[0055] The connecting surface of the two wooden boards can be set to be a 45-degree inclined surface, and the first connecting groove 41 and the second connecting groove 51 are respectively located on the connecting surfaces of the two wooden boards. The connecting piece can realize the assembly or connection of the two wooden boards at a ninety-degree angle. By opening a first groove 11 at the junction of the connecting piece body 1 and the second connecting part 3, corresponding to the position of the second shoulder 513, when the second connecting part 3 slides in the second connecting groove 51, granular impurities such as wood chips and dust generated by the wooden board during the installation process can be collected or stored to ensure that the second connecting part 3 slides smoothly in the second connecting groove 51, that is, the installation convenience of the two wooden boards is improved, and the first connecting part 2 is clamped in the first connecting groove 41 on one of the wooden boards by elastic deformation of the elastic arm 22, and the second connecting part 3 is embedded in the second connecting groove 51 on the other wooden board, and cooperates with a step of sliding or pushing the wooden board, so that the connecting piece reaches a fixed position in the second connecting groove 51, ensuring the relative installation position of the two wooden boards, and one of the wooden boards can be disassembled and reassembled in case of damage or other circumstances, which is convenient to operate.

[0056] The connecting surface of the two wooden boards can also be set as a vertical plane. Similarly, the first connecting groove 41 and the second connecting groove 51 are respectively processed on the connecting surfaces of the two wooden boards. The two wooden boards can be assembled in the horizontal direction through the connecting piece.
