DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1-Figure 3As shown, a sofa composite corner structure includes a first fixed side panel 1, a second fixed side panel 2 is arranged above the first fixed side panel 1, a card slot 11 is provided on the left inner wall of the first fixed side panel 1, and a connecting block 18 is fixedly provided on the outer surface of the lower end of the second fixed side panel 2. The connecting block 18 is clamped on the inner side of the card slot 11. The staff passes the connecting rod 12 through the left inner wall of the first fixed side panel 1 and the inner side of the fixing hole 19, so that the fixing block 14 is in close contact with the rear end surface of the first fixed side panel 1. At the same time, the limit block 13 is threadedly connected to the connecting rod 12 through the provided threaded hole 15, thereby fixing the second fixed side panel. 2 is movably connected to the first fixed side panel 1, so that the staff can adjust the angle of the corner. The staff wraps the corner of the sofa with the first fixed side panel 1 and the second fixed side panel 2. The countersunk holes 6 are convenient for the staff to fix the first fixed side panel 1 and the second fixed side panel 2 to the sofa with screws. A plurality of groups of protective pads 5 are provided on the inner side of the corner wrapping mechanism. The protective pads 5 are used to separate the first fixed side panel 1 and the second fixed side panel 2 from the sofa respectively, so as to protect the surface of the sofa. At the same time, since the protective pads 5 have a certain elasticity, they can prevent the screws from loosening after the staff fixes the corner wrapping mechanism.

[0025] like Figure 4-Figure 6 As shown, a sofa composite corner wrapping structure, when the staff needs to adjust the size of the wrapping angle, stretch the first extension plate 3 and the second extension plate 4, and pull the extension rod 16 out from the inside of the slide 7. At this time, the size of the wrapping angle can be adjusted according to work needs. The staff presses the limit plate 9 to place the fixed block 17 inside the fixed groove 8, slides the fixed block 17 and the extension rod 16 into the inside of the slide 7, and the upper surface of the extension rod 16 is flush with the horizontal plane of the first fixed side plate 1. Loosen the limit plate 9, and push the limit plate 9 to the right through the spring 10. Move to limit the fixed block 17 to prevent the fixed block 17 from slipping out of the inside of the fixed groove 8. Similarly, the second extension plate 4 and the second fixed side plate 2 are connected in the same way. After the installation is completed, the protective pad 5 is glued to the surface of the first fixed side plate 1 and the second fixed side plate 2. When the staff needs to adjust the size of the wrap angle, they only need to stretch the second extension plate 4 and the first extension plate 3 outward, which greatly reduces the labor intensity of the staff, facilitates the workers' operation, improves the practicability of the equipment, reduces the investment cost, and improves the market competitive advantage.

[0026] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
