Description

Technical Field

[0001] This application relates to the technical field of sofas, specifically to a sofa leg frame connecting mechanism and the sofa thereof. Background Technology

[0002] Sofas are a common type of furniture used in homes and offices. They typically consist of a seat cushion and a support frame, with sofa legs positioned below the support frame. Traditionally, the support frame and sofa legs are connected using screws and bolts. For example, a quick-assembly sofa support frame disclosed in application number CN202322062692.X includes a frame, support legs for supporting the frame, and a first screw connecting the frame and the support legs. A non-circular convex shank is fixedly installed on either side of the support leg opposite the frame. The block has a groove on one side that matches the protrusion; each of the support legs or frames has at least one first through hole and a first threaded hole corresponding to the first through hole. When the protrusion is inserted into the groove, the first through hole and the corresponding first threaded hole are coaxial. At this time, the first screw passes through the first through hole and is threadedly connected to the corresponding first threaded hole. Although this solution improves the assembly efficiency to a certain extent, it still inevitably requires the use of screws for connection and assembly, which leads to a complex disassembly and assembly process. Moreover, the screws may loosen during long-term use, causing structural instability. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the prior art, this application provides a sofa leg frame connection mechanism that does not require screws or other additional connectors, making the assembly and disassembly of the entire frame more convenient and quick, and less likely to cause the connection to loosen.

[0004] To solve the above-mentioned technical problems, the technical solution adopted in this application is as follows: a sofa leg frame connecting mechanism, the structure of which includes a sofa leg and a connecting beam. The sofa leg is provided with a vertically extending slot, and the end of the corresponding connecting beam is provided with a snap-fit ​​connector that engages with the slot. The snap-fit ​​connector includes a plug that engages with the slot and an abutment block for abutting against the inner wall of the sofa leg. The snap-fit ​​connector is inserted into the slot from above, so that the abutment block abuts against the inner wall of the sofa leg.

[0005] By adopting the above structure, this application provides vertically extending slots on the sofa legs and corresponding snap-fit ​​connectors at the ends of the connecting beams. When assembling the sofa legs and connecting beams, simply insert the snap-fit ​​connectors downwards from the top of the slots, allowing the inserts in the snap-fit ​​connectors to enter the slots and the abutting blocks to abut against the inner wall of the sofa legs, thus achieving the connection between the two. This connection method does not require screws or bolts, nor any other additional connectors; simply snapping the slots and snap-fit ​​connectors together achieves the connection. Disassembly is achieved by lifting the connecting beams upwards from the slots, making the operation simpler and faster, and preventing loosening during use. The resulting sofa leg frame connection mechanism is also more stable.

[0006] Furthermore, the sofa leg is provided with at least two slots, which are set at a 90-degree angle to each other. With this structure, two perpendicular connecting beams can be assembled on one sofa leg at the same time, thus forming a complete frame structure consisting of four beams and four sofa legs to support the sofa cushions.

[0007] Furthermore, the cross-section of the sofa leg is circular, and the abutment block in the corresponding snap-fit ​​connector is adapted to the inner wall of the sofa leg, which has a circular cross-section. With this structure, when the snap-fit ​​connector is snapped into the slot, full contact and abutment between the abutment block and the inner wall of the sofa leg can be achieved, improving the firmness of the connection between the two.

[0008] Furthermore, the circular cross-section sofa leg is composed of a first connecting part at the top and a second connecting part at the bottom. The cross-section of the second connecting part is smaller than that of the first connecting part, and the slot is provided on the first connecting part. With this structure, a larger contact area can be provided between the slot and the sofa leg, achieving a more stable connection between the two. The smaller cross-section of the second connecting part at the bottom can lower the center of gravity, making it easier to move the sofa.

[0009] Furthermore, the cross-section of the sofa leg is rectangular, and the abutment block in the corresponding snap-fit ​​connector is adapted to the inner wall of the sofa leg with a rectangular cross-section. With this structure, when the snap-fit ​​connector is snapped into the slot, full contact and abutment between the abutment block and the inner wall of the sofa leg can be achieved, improving the firmness of the connection between the two.

[0010] Furthermore, the snap-fit ​​connector extends end to end along the thickness direction of the connecting beam, and the extension length of the snap-fit ​​groove is equal to the extension length of the snap-fit ​​connector. This structure provides the snap-fit ​​connector with sufficient extension length and area, improving the connection strength between it and the sofa leg after snap-fitting.

[0011] Furthermore, the thickness of the insert block is adapted to the extension width of the slot, meaning that after the two are inserted and fitted together, there is almost no gap between them, thus avoiding shaking after the fastening and affecting stability.

[0012] Furthermore, when the connecting beams and the two slots on the sofa legs are engaged, there is a gap between the abutting blocks on the two adjacent connecting beams. With this structure, after assembly, the two adjacent connecting beams do not interfere with each other and achieve full contact with the inner wall of the sofa legs, thus improving the stability of the connection.

[0013] Furthermore, the connecting beams are solid beams, and each connecting beam is provided with multiple connecting holes that penetrate along its vertical thickness direction. The connecting holes are used to connect the sofa cushions. Specifically, self-tapping screws are inserted into the connecting holes, and the upper ends of the self-tapping screws are connected to the sofa cushions to assemble a complete sofa structure.

[0014] This application also provides a sofa that includes the sofa leg frame connecting mechanism described above. This sofa allows for quick assembly and disassembly of the sofa frame. Moreover, the assembly and disassembly process does not require any additional connecting parts such as screws or bolts. It is only necessary to directly snap the connecting beam and the sofa legs together. The operation is simple and quick, and it is not easy to loosen during use, making the structure more stable.

[0027] As attached Figure 1-9The image shows a sofa leg frame connecting mechanism according to this application. The mechanism includes a sofa leg 1 and a connecting beam 2. The sofa leg 1 has a vertically extending slot 101. The end of the connecting beam 2 has a corresponding locking connector 201 that engages with the slot 101. The locking connector 201 includes an insertion block 202 that inserts into the slot 101 and an abutment block 203 that abuts against the inner wall of the sofa leg 1. The locking connector 201 is inserted into the slot 101 from above. This allows the abutting block 203 to abut against the inner wall of the sofa leg 1. Specifically, this application provides a vertically extending slot 101 on each sofa leg 1, and a corresponding snap-fit ​​connector 201 at each end of the connecting beam 2. The snap-fit ​​connector 201 and the slot 101 are connected and engaged with each other to assemble the overall sofa leg frame connection mechanism. This process does not require additional screws or other connecting parts, nor does it require any turning action. Disassembly and assembly can be done directly by snapping and disassembling, making the operation simple and quick.

[0028] By adopting the above structure, this application provides vertically extending slots on the sofa legs and corresponding snap-fit ​​connectors at the ends of the connecting beams. When assembling the sofa legs and connecting beams, simply insert the snap-fit ​​connectors downwards from the top of the slots, allowing the inserts in the snap-fit ​​connectors to enter the slots and the abutting blocks to abut against the inner wall of the sofa legs, thus achieving the connection between the two. This connection method does not require screws or bolts, nor any other additional connectors; simply snapping the slots and snap-fit ​​connectors together achieves the connection. Disassembly is achieved by lifting the connecting beams upwards from the slots, making the operation simpler and faster, and preventing loosening during use. The resulting sofa leg frame connection mechanism is also more stable.

[0029] As attached Figure 1-5 As shown, the sofa leg 1 described in this application is provided with at least two slots 101, which are arranged at a 90-degree angle to each other. Specifically, the two slots are respectively arranged at a 90-degree angle to each other on the circumferential side wall of the sofa leg 1. With this structure, two perpendicular connecting beams 2 can be assembled on one sofa leg 1 at the same time, thus forming... Figure 1-4 The complete frame structure shown consists of four connecting beams 2 and four sofa legs 1, which provide support for the sofa cushions 3.

[0030] As attached Figure 1-5 As shown, the sofa leg 1 described in this application has a circular cross-section, and the corresponding abutment block 203 in the snap-fit ​​connector 201 is adapted to the inner wall of the sofa leg 1 with a circular cross-section; specifically, as shown in the attached... Figure 4 and 5As shown, there is a gap between the snap-fit ​​connector 201 at the end of the connecting beam 2 and the end face of the connecting beam. This gap is exactly matched with the wall thickness of the side wall of the sofa leg 1, and the curvature of the bend is also matched with the curvature of the side wall of the sofa leg 1. In this way, when the snap-fit ​​connector 201 is snapped into the slot 101, the end face of the connecting beam 2 is located on the outer circumferential surface of the side wall of the sofa leg 1, while the abutment block 203 is located on the inner wall of the side wall of the sofa leg 1 and abuts against it respectively. When the snap-fit ​​connector 201 is snapped into the slot 101, the abutment block 203 and the inner wall of the sofa leg 1 can be fully contacted and abutted, improving the firmness of the connection between the two.

[0031] As attached Figure 4-5 As shown in the figure, the circular cross-section sofa leg 1 described in the second panel application is composed of a first connecting part 102 located at the top and a second connecting part 103 located at the bottom. The cross-section of the second connecting part 103 is smaller than that of the first connecting part 102. The slot 101 is provided on the first connecting part 102. Specifically, the first connecting part located at the top is a hollow cylindrical structure, and the second connecting part located at the bottom is a frustum-shaped structure with a gradually decreasing cross-section. It can be a solid or a hollow structure. With this structure, the larger cross-section of the first connecting part 102 at the top can provide a larger contact area between the connector 201 and the sofa leg 1, achieving a more stable connection between the two. The smaller cross-section of the second connecting part 103 at the bottom can lower the overall center of gravity of the sofa, making it more stable and convenient for moving the sofa.

[0032] As another example, the cross-section of the sofa leg 1 described in this application is rectangular, and the abutment block 203 in the corresponding snap-fit ​​connector 201 is adapted to the inner wall of the sofa leg 1 with a rectangular cross-section. Specifically, the sofa leg 1 can be a structure with a square or rectangular cross-section. With this structure, when the snap-fit ​​connector 201 is snapped into the snap-fit ​​groove 101, the abutment block 203 and the inner wall of the sofa leg 1 can be fully contacted and abutted, improving the firmness of the connection between the two.

[0033] As attached Figure 4-5 As shown, the snap-fit ​​connector 201 of this application extends end to end along the thickness direction of the connecting beam 2, and the extension length of the snap-fit ​​groove 101 is equal to the extension length of the snap-fit ​​connector 201; that is, the snap-fit ​​connector 201 extends at the same height as the connecting beam 2 along the thickness direction of the upper and lower vertical directions; with this structure, the snap-fit ​​connector 201 can be given sufficient extension length and area, which improves the connection firmness between it and the sofa leg 1 after snap-fitting.

[0034] As an example, see attached Figure 1-4As shown, the thickness of the insert 202 described in this application is adapted to the extension width of the slot 101. That is, after the two are inserted and matched, there is almost no gap between them, which avoids shaking after fastening and affecting stability. However, they can be separated under external force without hindering their disassembly and assembly.

[0035] As attached Figure 1 , Figure 3 and Figure 7 As shown, when the connecting beam 2 and the two slots 101 on the sofa leg 1 are engaged with each other, the abutment blocks 203 on the two adjacent connecting beams 2 have gaps between each other; that is, the two adjacent abutment blocks 203 will not contact or interfere with each other. With this structure, after assembly, the two adjacent connecting beams 2 will not interfere with each other and will fully abut against the inner wall of the sofa leg 1, thereby improving the stability of the connection.

[0036] As attached Figure 1-2 and Figure 7 As shown, the connecting beam 2 described in this application is a solid beam. Each connecting beam 2 is provided with multiple connecting holes 204 that penetrate along its vertical thickness direction. The connecting holes 204 are used for connecting the sofa cushion 3. Specifically, by inserting self-tapping screws 4 into the connecting holes 204, the upper end of the self-tapping screws 4 is connected to the sofa cushion 3, thereby assembling a complete sofa structure.

[0037] As attached Figure 8-9 As shown, this application also provides a sofa containing the sofa leg frame connecting mechanism described above. This sofa allows for quick assembly and disassembly of the sofa frame without the need for any additional connecting parts such as screws or bolts. The connecting beam and sofa legs can be directly snapped together, making the operation simple and quick. It is also less prone to loosening during use, resulting in a more stable structure. Specifically, the sofa cushion is placed on the sofa leg frame connecting mechanism, and then an automatic screw is inserted into the connecting hole on the connecting beam to connect with the sofa cushion, thus forming a complete sofa structure.

[0038] The sofa with the sofa leg frame connecting mechanism described in this application simplifies the connection steps and processes between the sofa leg 1 and the connecting beam 2. It eliminates the need for additional connecting parts such as screws and bolts, as well as the need for unscrewing, disassembly, and assembly, thereby reducing the difficulty of installation, effectively lowering installation costs, and improving installation efficiency. This connection method also makes it less likely for the connecting parts to detach during use, resulting in a more stable connection.
