Detailed Description

In the following description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like refer to the orientation or position relationship shown in the drawings, and are only for convenience of description and simplification of the description, but do not refer to or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus are not to be construed as limiting the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1, fig. 2, fig. 3, fig. 4, fig. 5, a removable leather sheath sofa, including leather sheath 13, seat 1 and back 2 all are provided with straining device, straining device includes fixing device 12 and rotary device, fixing device 12 includes pressing from both sides tight seat 8 and moving clamp 9, press from both sides tight seat 8 and move clamp 9 and directly be provided with torsional spring 10, rotary device includes axis of rotation 3 and rotation seat 5, be provided with elasticity locating part 6 on the axis of rotation 3, it is provided with spacing arch 7 with locating part 6 assorted to rotate seat 5, axis of rotation 3 is located and rotates seat 5 is inside to be rotated, 13 one end of leather sheath twines with axis of rotation 3 and cooperates, the other end is through moving clamp 9 and pressing from both sides tight seat 8 and press from both. When the leather sheath 13 of the sofa needs to be replaced, the old leather sheath 13 is detached, one end of the new leather sheath 13 is clamped through the clamping seat 8 and the movable clamp 9 in a matching manner, then the leather sheath 13 is wound around the surface of the seat 1 or the backrest 2 to reach the rotating device at one end of the seat 1 or the backrest 2 far away from the fixing device 12, then the other end of the leather sheath 13 is inserted into the limiting groove 14 on the rotating shaft 3, then the rotating cap 4 connected with the rotating shaft 3 is rotated, the rotating shaft 3 winds the leather sheath 13 on the rotating shaft 3, the rotating cap 4 is continuously rotated to enable the leather sheath 13 to be completely tightened and attached to the surface of the sofa, then the decorative plate 11 hinged to the seat 1 or the backrest 2 is put down, the decorative plate 11 presses the edge of the leather sheath 13, the sofa with the leather sheath 13 replaced is more attractive, in order to facilitate the detachment of the leather sheath 13, a section of stroke for the limiting protrusion 7 to move is arranged in the rotating seat 5, through removing spacing arch 7 for locating part 6 breaks away from spacing arch 7, thereby it is spacing to cancel, makes axis of rotation 3 can reverse the rotation transfer leather sheath 13 break away from axis of rotation 3, thereby changes.
