[0030] Embodiment:

[0031] The embodiment of the present application discloses a single-person sofa frame structure. Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , including a base 1, and an auxiliary mechanism is provided on the top of the base 1;

[0032] The auxiliary mechanism includes a support frame 2, which is located at the top of the base 1, and an arc-shaped plate 3 is embedded in the support frame 2. Two grooves 4 are provided on the rear side of the arc-shaped plate 3, and a positioning block 15 is embedded in the bottom groove 4. The rear side of the positioning block 15 extends to the inside of the support frame 2. Connecting plates 5 are fixedly connected on both sides of the positioning block 15. Guide rods 6 are movably embedded in the two connecting plates 5. The two guide rods 6 are fixedly embedded in the support frame 2. Memory springs 7 are fixedly connected between the two connecting plates 5 and the support frame 2. The two memory springs 7 are respectively sleeved on the outside of the two guide rods 6. A handle 8 is fixedly embedded in the rear side of the positioning block 15.

[0033] See also Figure 3 A connecting component is provided on the outside of the handle 8, and the connecting component includes three springs 9. The three springs 9 are embedded between the arc plate 3 and the base 1, and the three springs 9 are evenly distributed. The handle 8 is made of non-slip material. By providing three springs 9, the arc plate 3 can be supported, so that the structure can be more effective during use. At the same time, because the handle 8 is made of non-slip material, the friction between the handle 8 and the palm can be strengthened, so that the operation efficiency can be higher;

[0034] See also Figure 1 A plurality of support rods 10 are fixedly connected between the support frame 2 and the base 1, and the plurality of support rods 10 are evenly distributed. A fixed frame 11 is fixedly embedded inside the support frame 2, and the fixed frame 11 matches the arc-shaped plate 3. A supporting rod 12 is fixedly embedded inside the fixed frame 11. By providing a plurality of support rods 10, a stronger support purpose can be provided to the support frame 2, so that the structure can be more firm and stable when in use;

[0035] See also Figure 2 Two reinforcement rods 13 are fixedly connected to the top of the support frame 2. The two reinforcement rods 13 are symmetrically arranged with the center line of the support frame 2 as the axis. Reinforcement sleeves 14 are screwed on the outer sides of the top ends of the two reinforcement rods 13. The two reinforcement sleeves 14 are made of flexible material. By setting up two reinforcement rods 13, it is convenient to install and disassemble the two reinforcement sleeves 14 later. At the same time, by setting up two reinforcement sleeves 14, the overall stability of the curved plate 3 during use can be made stronger.

[0036] The implementation principle of this embodiment is as follows: When storage is required, the handle 8 can be grasped and pulled, and then the positioning block 15 and the two connecting plates 5 will move accordingly. When the two connecting plates 5 move, the two memory springs 7 will be stressed and deformed, being in a stretched state. Since there are two guide rods 6, and the two guide rods 6 respectively match the two connecting plates 5, the positioning block 15 can be made to maintain a horizontal straight track when moving. When the positioning block 15 disengages from the arc-shaped plate 3, the arc-shaped plate 3 can be pressed downward to extend it between the support frame 2 and the multiple support rods 10, completing the storage operation. After the multiple springs 9 are all compressed to the minimum limit, the handle 8 can be released. Subsequently, the positioning block 15 will be affected by the rebound of the two memory springs 7 and extend into the top groove 4, completing the positioning operation of the arc-shaped plate 3 again. Through the above structure, the effect of being able to quickly carry out storage and maximizing the reduction of its overall occupied space is achieved, solving the problem that because the existing sofa frame structure is a fixed integrated structure as a whole and does not have a storage function, it is not easy to move, and it will be time-consuming and laborious during assembly and handling.

[0037] At the same time, through the mutual cooperation of the two reinforcing rods 13 and the two reinforcing sleeves 14, the purpose of further supporting the arc-shaped plate 3 can be achieved, so that the service life can be longer during the later use period. And because the two reinforcing sleeves 14 are both made of flexible materials, their contact with the sofa fabric can be made more fitting.

[0038] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
