Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of furniture, in particular to a surface sofa with prolonged service life. BACKGROUND

[0002] The surface sofa is loved by the majority of customers due to its good skin texture. The surface layer material of the surface sofa mainly includes leather, cotton, wool, etc.

[0003] In the prior art, the surface layer of the surface sofa is fixed, so it is difficult to care for: 1. The side in contact with the human body is always worn and aged, so after a period of use, the surface sofa often has scratches and holes on the side in contact with the human body; 2. Since the surface layer is fixed, it is difficult to apply care liquid.

[0004] Therefore, it is necessary to develop a surface sofa with prolonged service life to improve the service life and practical value of the surface sofa. SUMMARY

[0005] The present application discloses a surface sofa with prolonged service life, which can rotate and adjust the surface layer by covering the top shaft and the bottom shaft, prevent only the side in contact with the human body from being worn and aged, facilitate maintenance with care liquid, and ultimately improve the service life and practical value.

[0006] A surface sofa with prolonged service life, which is composed of a sofa seat and a backrest; the backrest is provided with support columns 1 on both sides, the bottom of the support column 1 is provided with an insertion block 2, the backrest is fixed to the sofa seat through the insertion block 2, the top and bottom of the support column 1 are respectively provided with a top shaft 4 and a bottom shaft 5; the middle of the support column 1 is provided with an adjusting groove 8, the adjusting groove 8 is provided with an adjusting rod 9, an adjusting shaft 6 is provided on the adjusting rod 9, and a spring 11 is arranged between the adjusting shaft 6 and the inner wall of the adjusting groove 8; the adjusting shaft 6 is fixedly connected with a back plate 7, the back plate 7 is provided with a foam layer 14; and the surface layer is covered on the top shaft 4 and the bottom shaft 5.

[0007] Further, the support column 1 is provided with an outer cover 15.

[0008] Further, the top of the support column 1 is provided with a first clamping groove 3, and the outer cover 15 is provided with a clamping block 16.

[0009] Further, the adjusting groove 8 is provided with a second clamping groove 10.

[0010] Further, the position of the adjusting shaft 6 is limited by using a card 12, and a through slot 13 is formed in the card 12.

[0011] Advantages of this invention:

[0012] 1. The present invention allows the decorative layer to be rotated and adjusted by covering the top and bottom pivots, thus preventing only the side in contact with the human body from constantly wearing and aging.

[0013] 2. This invention can effectively use contact lens solution: after applying the solution to one side, rotate it to the other side, and repeat this process. Using the solution does not affect the use of the device.

[0014] 3. The back panel and foam layer can be adjusted via the adjusting shaft: When the spring is not compressed, the back panel and foam layer press against the finish layer, keeping the finish layer under a certain tension, and the foam layer can enhance the softness and comfort of the sofa; when the spring is compressed, the tension of the finish layer is eliminated, and adjusting the finish layer at this time will not cause wear.

[0015] 4. This invention is particularly effective when the surface layer is made of genuine leather: by adjusting the surface layer and using care liquid for maintenance, it effectively alleviates wear and aging of the surface layer, improves the aesthetics of the upholstered sofa, and at the same time increases the service life and practical value of the upholstered sofa.

[0021] Example 1

[0022] A sofa with extended service life comprises a sofa seat and a backrest. Support columns 1 are located on both sides of the backrest, with insertion blocks 2 at the bottom of each support column 1. The backrest is fixed to the sofa seat via the insertion blocks 2. A top pivot 4 and a bottom pivot 5 are respectively installed through the top and bottom of the support columns 1. An adjustment groove 8 is located in the middle of the support column 1, with an adjustment rod 9 inside the groove 8. An adjustment shaft 6 is installed through the adjustment rod 9, and a spring 11 is installed between the adjustment shaft 6 and the inner wall of the adjustment groove 8. The adjustment shaft 6 is fixedly connected to a back panel 7, which has a foam layer 14. The upholstery layer covers the top pivot 4 and the bottom pivot 5. An outer cover 15 is provided on the outside of the support column 1. A first slot 3 is located at the top of the support column 1, and a locking block 16 is provided on the outer cover 15. A second slot 10 is provided inside the adjustment groove 8. A card 12 is used to limit the position of the adjustment shaft 6 when adjusting it, and a through groove 13 is provided on the card 12.

[0023] When the above-mentioned upholstered sofa is in use, the springs are not compressed, the back panel and foam layer press against the upholstery layer, so that the upholstery layer maintains a certain tension, and the foam layer can enhance the softness and comfort of the sofa.

[0024] To adjust the position of the finish layer, compress the spring, insert a card into the second slot, and then rotate the top and bottom pivots; once adjusted, remove the card.

[0025] In conclusion, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
