DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0022] Embodiment 1:

[0023] See also Figure 1-4 A sofa cushion fixing structure comprises a sofa seat body 1 and a sofa cushion body 2. Quick-install through slots 3 are provided on both sides and the back of the sofa seat body 1. Quick-install straps 4 and matching straps 5 are fixedly connected on both sides and the back of the sofa cushion body 2. One end of the matching strap 5 is fixedly connected with a carrying seat 6. A positioning mechanism 7 is installed on the inner side of the carrying seat 6. The positioning mechanism 7 is used to cooperate with the quick-install strap 4 to fix the sofa cushion body 2. Positioning seats 8 are fixedly connected on both sides and the back of the sofa seat body 1. The positioning seats 8 are used to support the carrying seat 6.

[0024] It can be understood that the mounting seat 6 is pushed to cause the assembly plate 16 to move into the positioning seat 8. When the limiting protrusion 18 contacts the inner wall of the mounting seat 6, the limiting protrusion 18 is squeezed by the mounting seat 6 through the structural characteristics of the limiting protrusion 18, causing the deformation plate 17 to deform. With the continuous movement of the assembly plate 16, when the limiting protrusion 18 corresponds to the positioning groove 19, the limiting protrusion 18 loses its limit, which can reset the deformation plate 17 and cause the limiting protrusion 18 to snap into the positioning groove 19, thereby forming a support for the mounting seat 6.

[0025] One side of the mounting seat 6 is fixedly connected with an assembly plate 16, both ends of the assembly plate 16 are fixedly connected with a deformation plate 17, one side of the deformation plate 17 is fixedly connected with a limiting protrusion 18, and a positioning groove 19 is opened inside the positioning seat 8, and the limiting protrusion 18 is connected with the positioning groove 19 by snapping;

[0026] Embodiment 2:

[0027] See also Figure 1-4, this embodiment provides a technical solution based on the first embodiment: the positioning mechanism 7 includes a central shaft 9, a positioning wheel 11, a positioning protrusion 12, an extension frame 13, a force plate 14 and a force rod 15, the inner side of the carrying seat 6 is rotatably connected to the central shaft 9, the middle part of the central shaft 9 is fixedly connected to the positioning wheel 11, the outer side of the positioning wheel 11 is fixedly connected to the positioning protrusion 12, the top of the carrying seat 6 is fixedly connected to the extension frame 13, the top of the central shaft 9 is fixedly connected to the force plate 14, the top of the force plate 14 is slidably connected to the force rod 15, and the bottom end of the force rod 15 is connected to the extension frame 13 by a clamping connection;

[0028] In summary, the quick-loading strap 4 and the matching strap 5 are passed through the quick-loading slot 3, and then the quick-loading strap 4 is inserted into the interior of the carrying seat 6 and led out from the end of the carrying seat 6, so as to form a splicing of the quick-loading strap 4 and the matching strap 5, so that the sofa cushion body 2 can be bound to the sofa seat body 1. After the initial binding, the force-bearing rod 15 is pulled upward to move it out of the extension frame 13, so as to release the lock of the central shaft rod 9, and then the central shaft rod 9 is rotated, and the connection between the central shaft rod 9 and the positioning wheel 11 is coordinated, which will be able to drive the positioning wheel 11 to rotate, so that the positioning protrusion 12 contacts the quick-loading strap 4, and then the quick-loading strap 4 is pressed between the positioning protrusion 12 and the inner wall of the carrying seat 6, so as to form the positioning of the quick-loading strap 4, and then the force-bearing rod 15 is pushed downward to make it snap into the extension frame 13, so as to form a quick fixation of the sofa cushion body 2;

[0029] Specifically, the outer side of the central shaft 9 is rotatably connected to a guide wheel 10, and the outer side of the guide wheel 10 is fixedly connected to an anti-skid pad. The setting of the guide wheel 10 can guide the quick-release strap 4 when the quick-release strap 4 passes, thereby improving the smoothness of the quick-release strap 4 when passing;

[0030] The top of the extension frame 13 is provided with a plurality of locking holes, and the bottom end of the force-bearing rod 15 is connected to the inside of the locking hole by snapping. Through the setting of the locking hole, the force-bearing rod 15 can be conveniently connected to the extension frame 13, thereby improving the stability of the application of the central shaft rod 9;

[0031] In detail, force-bearing inclined surfaces are provided on both sides of the limiting protrusion 18, and wear-resistant pads are fixedly connected to the outer sides of the force-bearing inclined surfaces. Through the setting of the force-bearing inclined surfaces, when the limiting protrusion 18 contacts the positioning seat 8, the deformation plate 17 can be deformed, and subsequently, the assembly plate 16 can be stuck into the positioning seat 8.

[0032] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0033] When working, first place the sofa cushion body 2 on the inner side of the sofa seat body 1, and make the quick-install strap 4 and the matching strap 5 pass through the quick-install slot 3, then pass the quick-install strap 4 into the inside of the carrying seat 6, and lead it out from the end of the carrying seat 6, so as to form the splicing of the quick-install strap 4 and the matching strap 5, so that the sofa cushion body 2 can be bound to the sofa seat body 1. After the initial binding, pull the force-bearing rod 15 upward to move it out of the extension frame 13, so as to release the lock of the central shaft rod 9, and then rotate the central shaft rod 9, and cooperate with the connection between the central shaft rod 9 and the positioning wheel 11, which will be able to drive the positioning wheel 11 to rotate, so that the positioning protrusion 12 contacts the quick-install strap 4, and then the quick-install strap 4 is pressed between the positioning protrusion 12 and the inner wall of the carrying seat 6, so as to form the positioning of the quick-install strap 4, and then push the force-bearing rod 15 downward to make it snap into the extension frame 13, so as to form a quick fixation of the sofa cushion body 2;

[0034] After the quick-release strap 4 and the carrying seat 6 are connected, the carrying seat 6 is aligned with the positioning seat 8, and then the carrying seat 6 is pushed to prompt the assembly plate 16 to move into the positioning seat 8. When the limiting protrusion 18 contacts the inner wall of the carrying seat 6, the limiting protrusion 18 is squeezed by the carrying seat 6 through the structural characteristics of the limiting protrusion 18, prompting the deformation plate 17 to deform. As the assembly plate 16 continues to move, when the limiting protrusion 18 corresponds to the positioning groove 19, the limiting protrusion 18 loses its limit, which can reset the deformation plate 17 and prompt the limiting protrusion 18 to be stuck in the positioning groove 19, thereby forming a support for the carrying seat 6.
