[0026] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The embodiment of the present application provides a rotating disk locking mechanism for a sofa and a rotating sofa, thereby solving the problem that the single sofas currently on the market mainly include two categories. One category is a fixed base with a reliable supporting structure, but it is not convenient to rotate during use and needs to be lifted up to adjust the direction; the other category is a rotating single sofa, which is similar to a rotating seat structure and has a rotating support member at the bottom, which is rotated by the rotating support member, but cannot be fixed during use.

[0028] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] The utility model discloses a rotating disc locking mechanism for a sofa and a rotating sofa.

[0030] According to the attached Figure 1-6 As shown, it includes a support base 1 and a rotating connection member 2 rotatably arranged on the top of the support base 1, and a rotating locking member 3 is arranged inside the rotating connection member 2, and the rotating locking member 3 includes;

[0031] A chuck 31 is vertically slidably disposed inside the rotating connector 2, and the bottom end of the chuck 31 is movably plugged into the supporting base 1;

[0032] A wedge-shaped top block 35 is disposed on one side of the chuck 31, and the wedge-shaped top block 35 is used to push the bottom end of the chuck 31 out from the top of the support base 1;

[0033] The locking spring 32 is disposed on the top of the chuck 31 , and is used to push the chuck 31 into the support base 1 .

[0034] A rotating support shaft 7 is fixedly connected to the middle of the support base 1 , and the rotating support shaft 7 is connected to the inside of the rotating connector 2 by a bearing.

[0035] A fixed disk 5 is fixedly connected between the bottom end of the rotating support shaft 7 and the supporting base 1. A plurality of clamping holes 6 are annularly arranged on the outer surface of the fixed disk 5. A clamping column 36 is fixedly welded to the bottom of the chuck 31. The clamping column 36 passes through the rotating connection 2 and is movably inserted into the inside of the clamping hole 6. There are four groups of clamping columns 36 and sixteen groups of clamping holes 6. When in use, they are always kept in the inner wall of the rotating connection 2, so that the chuck 31 can rotate synchronously with the rotating connection 2.

[0036] A slide groove 37 is provided at the bottom of the chuck 31 , and a guide frame 34 is slidably connected inside the slide groove 37 . A wedge-shaped top block 35 is fixedly connected to one end of the guide frame 34 , and a self-locking handle 4 is installed at the other end of the guide frame 34 .

[0037] The locking spring 32 and the chuck 31 are both movably sleeved on the outer surface of the rotating support shaft 7 , and a fixed retaining ring 33 is fixedly sleeved on the outer surface of the upper end of the rotating support shaft 7 .

[0038] The self-locking handle 4 includes:

[0039] A sliding bar 41, one end of which is fixedly connected to the guide frame 34, and a fixed stopper 44 is disposed inside the other end of the sliding bar 41 for transverse sliding;

[0040] The locking seat 42 has a J-shaped groove 43 in the middle, the sliding bar 41 is movably inserted into the locking seat 42, and the fixed baffle 44 is slidably connected to the inside of the J-shaped groove 43. When the fixed baffle 44 slides into the bending part at the end of the J-shaped groove 43, the locking spring 32 pulls the sliding bar 41, making it tend to slide inward, thereby ensuring that the fixed baffle 44 is stuck in the bending part at the end of the J-shaped groove 43.

[0041] A rotating sofa comprises a sofa body 8, wherein a rotating connector 2 is fixedly mounted on the bottom of the sofa body 8 by means of bolts.

[0042] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0043] When the device is in use, the fixed stopper 44 is pulled outward along the J-shaped groove 43 to the end, and then the fixed stopper 44 is moved horizontally so that it enters the bent part of the end of the J-shaped groove 43, thereby fixing the fixed stopper 44. In this process, the fixed stopper 44 drives the guide frame 34 to slide through the sliding bar 41, so that the wedge-shaped top block 35 enters the inside of the slide groove 37, and the chuck 31 is pushed upward, so that the locking spring 32 is compressed, so that the clamping column 36 is moved out from the inside of the clamping hole 6, and the end of the clamping column 36 is kept in the inner wall of the rotating connection member 2. At this time, the rotating connection member 2 can rotate freely on the top of the support base 1, and the fixed stopper 44 is moved out from the end of the J-shaped groove 43. At this time, under the action of the locking spring 32, the wedge-shaped top block 35 slides to the outside of the slide groove 37, and the clamping column 36 falls back. By rotating the rotating connection member 2, when the clamping hole 6 is facing the clamping column 36, the clamping column 36 automatically enters the inside of the clamping hole 6 for fixing, thereby facilitating rotation and locking.

[0044] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
