Description

Technical Field

[0001] The utility model relates to the technical field of leather sofas, in particular to a leather sofa with replaceable surface. Background Art

[0002] Leather sofas are a common type of furniture. They are usually made of animal leather such as cowhide, pigskin, horsehide, donkey skin, etc. They have natural pores and leather grain, and feel plump, soft, and elastic. The advantages of leather sofas include luxury, atmosphere, fashion, as well as good comfort and durability. However, the maintenance of leather sofas is relatively complicated and requires regular cleaning and maintenance to prevent leather aging and damage. When the sofa is damaged, its surface needs to be replaced.

[0003] The existing leather sofa is connected to the sofa frame by fastening nails. When the leather is damaged, the fastening nails need to be removed to replace new leather. When the new leather is installed on the sofa frame, it still needs to be connected with the fastening nails. Since the fastening nails have been removed once, nail holes have appeared in the sofa frame, making the secondary fastening effect of the fastening nails poor.

[0004] Therefore, we propose a method that can replace fastening nails as a connection method between the leather and the sofa frame, so that the leather can still be firmly attached to the surface of the sofa frame, so as to improve the effect of leather replacement and provide a leather sofa with replaceable surface.
