[0024] Reference Figure 1-6The utility model provides an embodiment: a sofa, including a sofa body 1, a first mounting groove 101 is opened at the lower end of the sofa body 1, a second mounting groove 102 is opened inside the sofa body 1, a third mounting groove 103 is opened inside the sofa body 1, the third mounting groove 103 and the second mounting groove 102 are both located outside the first mounting groove 101, a push groove 104 is opened at the lower end of the sofa body 1, and a mounting ring 11 is connected to the sofa body 1 through a pin shaft for positioning and rotation. The mounting ring 11 is located in the first mounting groove 101, and the mounting ring 103 is located inside the sofa body 1. The inner wall of the sofa body 1 is slidably connected with a pillar 12, one end of which is fixedly connected with a limiting plate 13, the diameter of which is equal to the length and width of the second mounting groove 102, and a clamping block 14 is slidably connected inside the sofa body 1, the clamping block 14 is located in the third mounting groove 103, one end of the clamping block 14 away from the first mounting groove 101 is fixedly connected with a spring 15, one end of the spring 15 away from the clamping block 14 is fixedly connected to the side wall of the third mounting groove 103, and the lower end of the clamping block 14 is fixedly connected with a pushing block 16, which is slidably connected to the pushing groove 104.

[0025] The arrangement pushes the pushing block 16 to slide in the pushing groove 104, so that the pushing block 16 squeezes the spring 15, and at the same time drives the clamping block 14 to slide into the third mounting groove 103, and then the clamping block 14 releases the limit on the pillar 12, so that the pillar 12 rotates out of the first mounting groove 101 through the mounting ring 11, and then when the pillar 12 is rotated to be perpendicular to the ground, the pillar 12 is pushed upward, so that the limiting plate 13 at one end of the pillar 12 contacts the inner top wall of the second mounting groove 102, thereby quickly completing the installation of the sofa body 1, wherein the diameter of the limiting plate 13 is equal to the length and width of the second mounting groove 102, so as to prevent the pillar 12 from shaking.

[0026] A backrest 2 is fixedly connected to the upper end of the sofa body 1, a fourth mounting groove 201 is provided on the side wall of the backrest 2, an electric push rod 21 is arranged inside the backrest 2, the electric push rod 21 is fixedly connected to the inner wall of the fourth mounting groove 201, a headrest 22 is fixedly connected to the output end of the electric push rod 21, the headrest 22 is slidably connected to the fourth mounting groove 201, and is used to control the length of the headrest 22 extending out of the backrest 2 by starting the electric push rod 21, which can be adjusted according to different usage habits of users to increase usage comfort.

[0027] The block 14 is T-shaped, and an inclined surface is provided at one end of the block 14 away from the spring 15, which is used to limit the spring 15 and directly push the pillar 12, so that the pillar 12 squeezes the block 14 to slide into the third mounting groove 103, and then the block 14 uses the elastic force of the spring 15 to push the block 14 out of the third mounting groove 103, thereby limiting the pillar 12.

[0028] The lower end of the sofa body 1 is fixedly connected with an anti-collision plate 3, and the anti-collision plate 3 is used to protect the lower end of the sofa body 1 during transportation to reduce wear.

[0029] A slide groove 202 is provided inside the backrest 2 and is located outside the fourth mounting groove 201 . A slider 23 is fixedly connected to the side wall of the headrest 22 and is slidably connected to the slide groove 202 to limit the headrest 22 and prevent the headrest 22 from directly sliding out of the slide groove 202 .

[0030] The electric push rod 21 is electrically connected to an external controller, and is used to control the extension and contraction of the electric push rod 21 through the controller, thereby controlling the position of the headrest 22 .

[0031] Working principle: First, by pushing the pushing block 16 to slide in the pushing groove 104, the pushing block 16 squeezes the spring 15 and drives the clamping block 14 to slide into the third mounting groove 103. Then the clamping block 14 releases the limit on the pillar 12. The pillar 12 rotates out of the first mounting groove 101 through the mounting ring 11. Then, when the pillar 12 is rotated to be perpendicular to the ground, the pillar 12 is pushed upward. The limiting plate 13 at one end of the pillar 12 contacts the top wall of the second mounting groove 102, thereby quickly completing the installation of the sofa body 1. Then, according to the different usage habits of users, the length of the headrest 22 extending out of the backrest 2 can be adjusted by starting the electric push rod 21 to increase the comfort of use.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
