[0032] Through the above technical solution, when the user needs to adjust the position of the sofa body 1, the user rotates and adjusts the sofa body 1. At this time, the plug-in end 9 of the fixed pin 8 will correspond to any adjustment socket. When the user sits down on the sofa body 1, due to the increase in the weight of the sofa body 1, the gravity of the sofa body 1 is greater than the elastic force of the fixed spring 15, so that the sofa body 1 drives the connecting push rod 11 to push downward, and the pushing end 12 of the connecting push rod 11 drives the fixed spring 15 to contract, so that the plug-in end 9 of the fixed pin 8 will be plugged into any adjustment socket 20, so that the position of the sofa body 1 after rotation can be fixed by relying on the weight of the user without manually inserting the pin.
[0033] In addition, when the position of the sofa body 1 needs to be adjusted again, the user leaves the sofa body 1. At this time, the weight of the sofa body 1 is reduced, and the elastic force of the fixed spring 15 is greater than the gravity of the sofa body 1. The fixed spring 15 stretches, thereby driving the pushing end 12 of the connecting push rod 11 to move upward, and the connecting push rod 11 drives the bottom plate 2 to move upward, so that the plug-in end 9 of the fixed pin 8 is disengaged from the adjustment socket 20, so that the sofa body 1 can be restored to the rotation state without the need for user operation.
[0034] Reference Figure 4-Figure 5 In some specific embodiments, a guide groove 17 is provided on the inner edge of the movable cavity 18, and the guide groove 17 is arranged along the height direction of the fixed seat 16. The guide groove 17 passes through the top of the fixed seat 16, and a guide slider 14 is provided on the outer edge of the pushing end 12, and the guide slider 14 slides in cooperation with the guide groove 17.
[0035] Through the above technical solution, when the pushing end 12 of the connecting push rod 11 slides along the movable cavity 18, the guide slider 14 of the pushing end 12 slides with the guide groove 17 of the movable cavity 18, thereby facilitating the guiding of the moving position of the pushing end 12; and under the limitation of the guide slider 14 by the guide groove 17, the connecting push rod 11 can only move up and down, thereby preventing the connecting push rod 11 from rotating and causing friction with the fixed spring 15.
[0036] Reference Figure 4-Figure 5 In some specific implementations, a first limiting ring 19 is provided on the top of the fixing seat 16 , and the first limiting ring 19 is located above the guide groove 17 .
[0037] Through the above technical solution, when the elastic force of the fixed spring 15 is greater than the gravity of the sofa body 1, the fixed spring 15 stretches. Since the first limiting ring 19 is located above the guide slide groove 17, it is convenient to limit the position of the guide slider 14 to prevent the connecting push rod 11 from being separated from the movable cavity 18 under the action of the elastic force.
[0038] Reference Figure 4-Figure 5In some specific embodiments, a second limiting ring 13 is provided on the outer edge of the connecting push rod 11 . The second limiting ring 13 is located above the pushing end 12 , and the second limiting ring 13 faces the fixing seat 16 .
[0039] Through the above technical solution, when the user sits down on the sofa body 1, the sofa body 1 drives the connecting push rod 11 to be pushed downward, and the connecting push rod 11 drives the second limiting ring 13 to conflict with the fixing seat 16, thereby avoiding the fixing seat 16 from colliding with the base plate 2, thereby improving the service life of the base plate 2.
