[0025] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0026] This application discloses a compressible modular sofa. (Refer to...) Figures 1-6A compressible modular sofa includes a base 1, with flipping components 2 on both sides of the base 1, a mounting shell 3 fixedly connected to the rear side of the top of the base 1, a lifting block 4 in the inner cavity of the mounting shell 3, a headrest 5 fixedly connected to the top of the lifting block 4 extending to the top of the mounting shell 3, and a limit component 6 fixedly connected to both sides of the mounting shell 3, and several slots 7 sequentially opened from top to bottom on both sides of the lifting block 4.

[0027] The flipping assembly 2 includes a handrail 201. The surface of the handrail 201 is movably connected to the base 1 via a pivot. A first screw 202 is fixedly connected to both the front and rear sides of the bottom of the handrail 201. A support leg 203 is threaded onto the surface of the first screw 202. A first spring 204 is provided inside the handrail 201. A moving block 205 is fixedly connected to both the front and rear sides of the first spring 204. An operating block 206 is fixedly connected to one side of the moving block 205. One side of the operating block 206 extends to the outside of the handrail 201. A positioning element is fixedly connected to the surface of the moving block 205. The positioning rod 207 extends through to the outside of the armrest 201 and is fitted with a positioning shell 208. The surface of the positioning shell 208 is fixedly connected to the base 1. By setting the flipping component 2, the armrest can be folded when the sofa is not in use, thereby compressing and storing the entire sofa. When the sofa is in use, the armrest 201 can be flipped to a vertical state and limited. In addition, the headrest 5 can be quickly installed, removed, and its height adjusted for convenient use. At the same time, the length of the support block 10 can be adjusted to facilitate the placement of the user's legs.

[0028] Reference Figure 1 , Figure 2 and Figure 6 A handwheel 8 is provided on the rear side of the base 1, and a second screw 9 is fixedly connected to the front side of the handwheel 8. The front end of the second screw 9 passes through the inner cavity of the base 1 and is fitted with a support block 10. The front side of the support block 10 passes through the front side of the base 1. The surface of the second screw 9 is rotatably connected to the base 1 through a bearing, and the surface of the second screw 9 is threadedly connected to the support block 10. By providing the handwheel 8, the user can easily rotate the second screw 9. By providing the support block 10, the user's legs can be supported. By providing the bearing, the rotation of the second screw 9 can be facilitated.

[0029] Reference Figure 4 and Figure 5The limiting component 6 includes a limiting box 601. The two limiting boxes 601 are fixedly connected to the two sides of the mounting shell 3 on opposite sides. The inner cavity of the limiting box 601 is provided with a pull plate 602. The two sides of the pull plate 602 are fixedly connected with a plug rod 603 and a pull rod 604 respectively. One end of the plug rod 603 passes through the limiting box 601 and the mounting shell 3 and extends into the inner cavity of the slot 7. A second spring 605 is sleeved on the surface of the pull rod 604. The two sides of the second spring 605 are fixedly connected to the pull plate 602 and the limiting box 601 respectively. One end of the pull rod 604 passes through the outer side of the limiting box 601 and is fixedly connected with a pull block 606. By setting the plug rod 603, it can be inserted into the slot 7 to fix the lifting block 4. By setting the pull block 606, it is easy for the user to pull the pull rod 604. By setting the second spring 605, it is easy for the two plug rods 603 to move towards the middle for reset.

[0030] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The inner cavity of the mounting shell 3 is fixedly connected to both sides of the slider 11, and the lifting block 4 is provided with sliding grooves 12 on both sides to cooperate with the slider 11. The surface of the first screw 202 is connected to the support leg 203 by a thread, and the surface of the moving block 205 is slidably connected to the inner wall of the armrest 201. By setting the slider 11 and the sliding groove 12, the movement of the lifting block 4 can be facilitated, and the range of movement of the lifting block 4 can be increased. By setting the support leg 203, it can support the entire sofa.

[0031] Working principle: When the user needs to use the sofa, they only need to adjust the two front and rear operating blocks 206 towards the center. The operating blocks 206 drive the two moving blocks 205 to move towards the center, compressing the first spring 204. The moving blocks 205 drive the two positioning rods 207 to move towards the center. Then, the armrests 201 can be flipped over through the cooperation of the pivot, so that the armrests 201 are perpendicular to the base 1. At the same time, the positioning rods 207 correspond to the positioning shell 208. Releasing the operating blocks 206, the first spring 204 returns to its original position, and through the cooperation of the moving blocks 205, the positioning rods 207 are inserted into the positioning shell 208, which can fix the armrests 201. When the sofa is not in use, the positioning rods 207 can be removed from the positioning shell 208, and then the two armrests 201 can be flipped towards the center, facilitating the transportation of the entire sofa. The wheel 8 can rotate the second screw 9, which in turn moves the support block 10 for adjustment. The support block 10 can support the user's legs and can be adjusted according to the user's needs. The pull block 606 can pull the pull rod 604, which moves the two pull blocks 606 away from each other and compresses the second spring 605. The pull block 606 moves the insertion rod 603 out of the slot 7, which can release the fixation of the lifting block 4 and the headrest 5. Then, not only can the height of the lifting block 4 and the headrest 5 be adjusted, but the headrest 5 and the lifting block 4 can also be disassembled for easy combination of the headrest 5 and the sofa. After the height of the headrest 5 is adjusted, the pull block 606 is released, and the second spring 605 returns to its original position. The pull block 606 will then move the insertion rod 603 into the slot 7 to fix the headrest 5.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
