The headrest is directly flipped upward and then released, and the headrest is automatically stuck and will not fall. This is mainly achieved by an internal latching tooth structure. However, during long-term use, the latching teeth are prone to wear and deformation, resulting in the problem that the headrest cannot be stuck in subsequent use, or it is stuck and cannot be separated for readjustment.

[0025] 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.

[0026] The utility model embodiment discloses a flip headrest device for a sofa.

[0028] A fixing member 21, which is fixedly mounted on the sofa;

[0029] A rotating connecting member 22 is rotatably disposed inside the fixing member 21, and the headrest body 1 is movably clamped on the top of the rotating connecting member 22;

[0030] A locking member 23, comprising:

[0031] The sliding shaft 231 is movably inserted into the fixing member 21, and the sliding shaft 231 rotates synchronously with the rotating connecting member 22;

[0032] The locking pin 235 is fixedly disposed at one end of the sliding shaft 231 , and the locking pin 235 is movably engaged with the fixing member 21 to fix the rotating connecting member 22 .

[0033] The fixing member 21 includes a fixing bar 211 and support portions 212 integrally formed at the top of both ends of the fixing bar 211 . The outer surfaces of both ends of the fixing bar 211 are provided with mounting holes 213 .

[0034] A plurality of fixing holes 214 are formed on the outer surface of a group of supporting parts 212 , and the locking pins 235 are movably inserted into the fixing holes 214 .

[0035] A circular plate 234 is fixedly welded to the end of the sliding shaft 231, and a locking pin 235 is fixedly welded to the inner wall of the circular plate 234. There are multiple locking pins 235 made of stainless steel, which is not easy to deform and rust. The inner diameter of the fixing hole 214 is slightly larger than the outer diameter of the locking pin 235 for easy insertion.

[0036] The rotating connecting member 22 includes a rotating supporting arm 221 rotatably disposed inside the two groups of supporting parts 212 , and a connecting shaft 223 for installation with the headrest body 1 is fixedly welded to the top of the rotating supporting arm 221 .

[0037] A connecting plate 224 and an inner hexagonal tube 222 are fixedly welded between the two sets of rotating support arms 221 . The sliding shaft 231 passes through the two sets of support parts 212 and the rotating support arms 221 . An outer hexagonal shaft 232 is fixedly arranged in the middle of the sliding shaft 231 . The inner hexagonal tube 222 is movably sleeved on the outer surface of the outer hexagonal shaft 232 .

[0038] A return spring 233 is movably sleeved on the outer surface of one end of the sliding shaft 231 close to the locking pin 235 , and a button 237 is rotatably connected to the other end of the sliding shaft 231 , and an anti-drop sleeve 236 is movably sleeved on the outer surface of the button 237 .

[0039] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0040] When the device is in use, the button 237 is pressed inwardly so that the button 237 pushes the sliding shaft 231 to slide. At this time, the end of the sliding shaft 231 drives multiple locking pins 235 to move out of the fixing hole 214 through the circular plate 234. At this time, the return spring 233 is compressed. At this time, the headrest body 1 is rotated to drive the rotating connection 22 to rotate. At this time, the rotating connection 22 drives the outer hexagonal shaft 232 to rotate through the inner hexagonal tube 222, so that the sliding shaft 231 rotates synchronously. When the headrest body 1 is rotated to a suitable position, the button 237 is released. Under the action of the return spring 233, the sliding shaft 231 slides outward, so that the locking pins 235 are inserted into the fixing hole 214 to complete the fixation, and the locking is more reliable and durable.
