[0027] As shown in Figure 1 , Figure 2 and Figure 3 a novel sofa base structure includes a plurality of support frames 1 and a plurality of support mechanisms 2. A plurality of support plates 13 are uniformly arranged between the inner walls of the support frame 1 along the front-rear direction. Rectangular grooves 3 are respectively arranged at the lower corners of the support frame 1. A blind hole 4 is arranged on the inner wall of the bottom of the rectangular groove 3. The support mechanism 2 includes a rod body 5. An insertion block 6 that cooperates with the rectangular groove 3 is arranged at the upper end of the rod body 5. A through hole 7 is arranged between the insertion block 6 and the rod body 5. A connecting rod 8 is rotatably arranged in the through hole 7. An insertion block two 9 that cooperates with the blind hole 4 is arranged at the upper end of the connecting rod 8. The lower end of the connecting rod 8 is connected with a disc 10. Slots 11 that are opposite left and right are arranged above the support frame 1. One end of the slot 11 far from the support frame 1 extends out of the support frame 1, and the cross section is a trapezoidal structure. The length of one end of the slot 11 close to the center of the support frame 1 is greater than the length of the other end. A limiting block 12 is inserted and cooperated in two mutually cooperating slots 11.
[0028] Through the above structure, the support frame 1 is respectively supported by inserting the support mechanism 2 into the rectangular groove 3 and the blind hole 4 below, and the support mechanism 2 and the support frame 1 are installed and disassembled by rotating and adjusting the angle of the insertion block two 9, so that the installation and disassembly are convenient. According to the required length of the sofa base, the support frames 1 are sequentially attached to each other, and then the connection is realized by inserting the limiting block 12 into the two mutually attached slots 11, so that the structure of the sofa base is adjustable and the application range is wider.
[0029] The length of the connecting rod 8 is equal to the length between the insertion block 6 and the rod body 5. The diameter of the disc 10 is equal to the diameter of the lower end of the rod body 5. The diameter of the blind hole 4 is smaller than the length of the rectangular groove 3. The length and width of the insertion block two 9 are respectively smaller than the length and width of the insertion block 6.
[0030] Through the above structure, the connecting rod 8 rotates in the rod body 5 to change the angle of the insertion block two 9, so that the insertion block two 9 can pass through the rectangular groove 3 and be inserted into the blind hole 4.
[0031] Embodiment 2
[0032] On the basis of Embodiment 1, please refer to Figure 4and appendix Figure 5
[0033] Above the described support frame 1, there are the same slots 11 opposite to each other front and back, and the distances from the slots 11 to the corners of the adjacent support frames 1 are the same.
[0034] With the above structure, the support frame 1 can be connected not only left and right but also front and back to form different sofa base structures.
[0035] An arc-shaped groove 14 is provided on the inner wall of the support frame 1 close to the slot 11, and a rubber block 15 is provided on the side wall of the limit block 12 to cooperate with the arc-shaped groove 14.
[0036] With the above structure, after the limit block 12 is inserted into the slot 11, the rubber block 15 is exactly located in the arc-shaped groove 14, making the fastening tighter and preventing it from moving up and down.
[0037] All the vertical corners of the limit block 12 are rounded; an inverted T-shaped groove 16 is provided at the upper end of the limit block 12.
[0038] With the above structure, the edge of the limit block 12 is round, avoiding bumps, and the limit block 12 can be disassembled more easily through the T-shaped groove 16, facilitating the installation and disassembly of the device.
[0039] The specific usage method is as follows: The support frame 1 is respectively supported by inserting the support mechanism 2 into the rectangular groove 3 and the blind hole 4 below, and the support mechanism 2 and the support frame 1 are installed and disassembled by rotating and adjusting the angle of the second insertion block 9, making the installation and disassembly convenient. According to the required length of the sofa base, the support frame 1 can be connected not only left and right but also front and back to form different sofa base structures, making the support frames 1 adjacent to each other in sequence, and then the connection is realized by inserting the limit block 12 into the two adjacent slots 11. After the limit block 12 is inserted into the slot 11, the rubber block 15 is exactly located in the arc-shaped groove 14, making the fastening tighter and preventing it from moving up and down. The limit block 12 can be disassembled more easily through the T-shaped groove 16, facilitating the installation and disassembly of the device, making the structure of the sofa base adjustable and having a wide range of applications.
