Description

Technical Field

[0001] This utility model relates to the field of frame technology, specifically to a foldable and deformable upholstered sofa frame. Background Technology

[0002] Foldable and deformable upholstered sofa frames are an innovative design aimed at improving the space utilization and versatility of furniture. These sofa frames are typically made of lightweight yet sturdy materials, such as aluminum alloy or reinforced plastic, ensuring structural stability while also facilitating movement and shape transformation.

[0003] However, upholstered sofa frames have some shortcomings in actual use. For example, the sofa frame is inconvenient to operate and lacks stability during folding and deformation, as well as lacking effective auxiliary restraint devices. This not only affects the user experience but also results in poor stability of the upholstered sofa frame.

[0004] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

There are two magnets 303. The inner wall of the adjustment groove is fixedly connected to one side of the magnets 303. The magnets 303 and magnets 302 are positioned opposite each other.

[0030] The inner wall of the folding assembly 2 has multiple mounting holes on both sides, with a total of four mounting holes. Every two mounting holes are located on the inner wall of the adjustment groove. The mounting holes are located on both sides of the inner wall of the adjustment groove. A spring-loaded telescopic rod 304 is fixed to the inner wall of the multiple mounting holes. The spring-loaded telescopic rod 304 consists of a telescopic rod one, a telescopic rod two, and a spring. One end of the telescopic rod one is nested and connected to the inner wall of the telescopic rod two through a sealing block or sealing gasket.

Limiting holes are provided on both sides of the limiting plate 301, and the inner wall of the limiting hole contacts one end of the limiting block 305.

[0031] Example 2:

[0032] like Figures 1-5As shown, according to an embodiment of the present utility model, a foldable and deformable upholstered sofa frame is provided with an auxiliary component 4 at one end of the folding component 2. The auxiliary component 4 includes an auxiliary ratchet 401 fixedly disposed with one end of a rotating rod 201 passing through the folding groove. An auxiliary block 402 is engaged with the teeth of the auxiliary ratchet 401. An auxiliary spring 403 is fixedly connected to one side of the auxiliary block 402. A fixing block 404 is fixed to one end of the auxiliary spring 403.

The auxiliary block 402 is located on the inner wall of the auxiliary opening.

[0034] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0035] In summary, with the help of the above-mentioned technical solution of this utility model, when the sofa needs to be unfolded, the user pulls the sofa armrest frame 203 and the sofa backrest frame 204, causing the folding column 202 to rotate around the rotating rod 201, which drives the sofa armrest frame 203 and the sofa backrest frame 204 to unfold from the folding slot, and the tabletop 205 unfolds with the sofa armrest frame 203 to form a flat surface, which can be used as a temporary tabletop;

[0036] Meanwhile, the limiting plate 301 set on the sofa armrest frame 203 moves on the inner wall of the folding column 202, and the magnet 302 set on one side of the limiting plate 301 and the magnet 303 set on one side of the inner wall of the folding column 202 are magnetically attracted to each other, ensuring that the components fit tightly after unfolding. The spring sleeve telescopic rod 304 is embedded in the mounting hole of the adjustment groove. The limiting block 305 set on the spring sleeve telescopic rod 304 extends under the action of the spring and inserts into the limiting holes on both sides of the limiting plate 301 to form a mechanical lock to prevent accidental unfolding or loosening. The auxiliary ratchet 401 is installed at the end of the rotating rod 201, and its teeth mesh with the auxiliary block 402. During the unfolding process, the auxiliary ratchet 401 rotates with the rotating rod 201. The auxiliary block 402 keeps in contact with the teeth of the auxiliary ratchet 401 under the tension of the auxiliary spring 403, restricting the unidirectional movement of the rotating rod 201 and ensuring the stability after unfolding.

[0037] When folding, the user connects the auxiliary block 402 to the limiting rod 6 via the limiting rope 5. The limiting rod 6 is inserted into the protective cover 7, releasing the restriction of the auxiliary block 402 on the auxiliary ratchet 401. After release, the user pushes the sofa armrest frame 203 and sofa backrest frame 204 in the opposite direction. At the same time, the limiting plate 301 moves on the inner wall of the folding column 202. The magnet 1 302 on the other side of the limiting plate 301 and the magnet 2 303 on the other side of the inner wall of the folding column 202 are attracted by magnetic force, ensuring that the parts fit tightly after folding. Meanwhile, the spring sleeve telescopic rod 304 is embedded in the mounting hole of the adjustment groove. The limiting block 305 set on the spring sleeve telescopic rod 304 extends out under the action of the spring and inserts into the limiting hole opened in the limiting plate 301, forming a mechanical lock to prevent accidental folding or loosening. A protective pad 8 is set at the connection between the sofa armrest frame 203 and the folding column 202 to reduce friction noise of metal parts and protect the user from being hit by hard objects during operation.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
