They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more, unless otherwise expressly defined.

[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0025] For clarity, in this invention, the side where the user sits is considered the front, and the opposite side is considered the back; the side closer to the center of the chair is considered the inside, and the opposite side is considered the outside.

[0026] like Figures 1 to 10 As shown, this utility model discloses a headrest mechanism with an adjustable clothes hanger, including: a headrest component; a fixed base 3 connected to the headrest component; and a clothes hanger including two hanging rods 4 on the left and right sides, with the opposite ends of the two hanging rods 4 rotatably mounted on the fixed base 3 so that the two hanging rods 4 can be retracted forward or extended backward; when the two hanging rods 4 are extended backward, the two hanging rods 4 can be used to hang clothes.

[0027] In this way, by setting the clothes hanger installed in the mounting hole 31 of the fixed base as two independently rotatable hanging rods 4, the angle between the two hanging rods 4 can be adjusted. When the clothes hanger is not in use, it can be folded forward so that it does not protrude from the back of the chair and is hidden. When the clothes hanger is in use, it can be unfolded backward so that it is easy to hang clothes, which is both beautiful and practical.

[0028] In this invention, the mounting base 3 has a through mounting hole 31. Two hanging rods 4 are rotatably mounted at opposite ends within the mounting hole 31 of the mounting base 3, with the other ends extending out of the mounting hole 31. To fix the angle between the two hanging rods 4, a groove 32 is formed on the inner surface of the mounting hole 31. A locking member 5 is provided within the groove 32, and the locking member 5 is connected to the bottom of the groove 32 via a first elastic member 7. The end of the locking member 5 near the hanging rod 4 extends out of the groove 32 and can press the two hanging rods 4 against the inner wall of the mounting hole 31. Therefore, by setting the locking member 5 to press the two hanging rods against the inner wall of the mounting hole, the angle between the two hanging rods 4 is fixed. In this design, because a groove 32 is formed on the inner surface of the mounting hole 31, the locking member 5 can move within the groove 32, thus preventing the locking member 5 from shifting. Furthermore, the cross-sectional shape of the groove 32 is polygonal, and the shape of the locking member 5 is adapted to the groove 32, thereby ensuring that the locking member 5 moves radially along the groove 32 without rotating or shifting. The locking member 5 has a limiting groove 52 on the side near the bottom of the groove 32. A mounting post 37 is provided at the bottom of the groove 32. One end of the first elastic member 7 is fitted onto the mounting post 37, and the other end of the first elastic member 7 is fixedly disposed within the limiting groove 52, thereby limiting the position of the first elastic member 7. Alternatively, in other embodiments, the position of the first elastic member 7 can be limited by providing a mounting post on the side of the locking member 5 near the bottom of the groove 32 or by creating a limiting groove at the bottom of the groove 32. The first elastic member 7 is preferably a spring.

[0029] In this design, one end of the hanging rod 4 that extends into the mounting hole 31 is provided with a pivot or rotating hole. The inner surface of the mounting hole 31 is provided with a rotating hole or pivot that matches the pivot or rotating hole on the hanging rod 4. The hanging rod 4 and the fixing seat 3 are rotatably connected through the pivot and rotating hole. Figure 6 and Figure 10 As shown, in this utility model, the end of the hanging rod 4 that extends into the mounting hole 31 is provided with a rotating shaft 42. The lower surface of the mounting hole 31 is provided with a rotating hole 36 that is adapted to the rotating shaft 42 on the hanging rod 4. Specifically, the rotating hole 36 is opened on the base 301. In order to prevent the rotating shaft 42 of the hanging rod 4 from coming out of the rotating hole 36, the fitting depth between the hanging rod 4 and the fixing seat 3 is greater than the distance between the side of the hanging rod 4 away from the rotating shaft 42 and the inner wall of the mounting hole 31, thereby ensuring that the rotating shaft 42 is always located in the rotating hole 36.

[0030] like Figure 10 As shown, each of the two hanging rods 4 has a plurality of toothed structures 41 at one end opposite to the other. The toothed structures 41 of the two hanging rods 4 mesh with each other, thereby preventing the two hanging rods 4 from misaligning and getting stuck. Moreover, the two hanging rods 4 can also be linked together by meshing the toothed structures 41. Only one hanging rod 4 needs to be rotated to make the other hanging rod 4 rotate accordingly, making the adjustment faster and more convenient.

[0031] In one embodiment, the locking member 5 always presses the two hanging rods 4 against the inner wall of the mounting hole to fix the angle between the two hanging rods 4. When adjusting the angle between the two hanging rods 4, a large force needs to be applied to overcome the friction between the hanging rods 4 and the inner wall of the mounting hole 31 so as to rotate the hanging rods 4.

[0032] In another embodiment, to reduce effort and wear on the two hanging rods 4 when adjusting their angles, a plug 6 that engages with the locking member 5 is provided to displace the locking member 5 and unlock the two hanging rods 4. In this invention, a first insertion port 33 communicating with the mounting hole 31 is opened on the side wall of the base 3. The first insertion port 33 communicates with the groove 32. A plug 6 is movably disposed within the first insertion port 33. The insertion end 61 of the plug 6 can extend into the groove 32 and engage with the locking member 5 to displace the locking member 5 and compress the first elastic member 7, thereby unlocking the two hanging rods 4. The user can freely adjust the rotation angle of the two hanging rods 4.

[0033] The groove 32 can be formed on the upper surface, front surface, rear surface or lower surface of the mounting hole 31. In this utility model, the example of the groove 32 being formed on the lower surface of the mounting hole 31 will be used for illustration.

[0034] When the groove 32 is formed on the lower surface of the mounting hole 31, the opening of the groove 32 faces upward, and the locking member 5 is located below the hanging rod 4. The locking member 5 can move up and down within the groove 32 to press the hanging rod 4 tightly against the upper surface of the mounting hole 31 or to create a gap between the hanging rod 4 and the upper surface of the mounting hole 31. The first insertion port 33 can be formed on the front or rear side of the fixing base 3. The locking member 5 is provided with a second insertion port 51. When the first elastic member 7 is reset, the second insertion port 51 of the locking member 5 is located above the first insertion port 33 of the fixing base 3, and the second insertion port 51 partially overlaps with the first insertion port 33. In this way, when the insertion end 51 of the plug 6 passes through the first insertion port 33 and is inserted into the second insertion port 51 of the locking member 5, it can drive the locking member 5 to move downward, and the locking member 5 no longer presses against the hanging rod 4, and the first elastic member 7 is compressed. In order to facilitate the insertion end of the plug 6 into the second insertion port 51 of the locking member 5, such as Figures 7 to 9 As shown, the second socket 51 is provided with a first guide slope 511, and the plug end 61 of the plug 6 is provided with a second guide slope 611 that is adapted to the first guide slope 511.

[0035] A torsion spring 8 for resetting the hanging rod 4 is also provided between the hanging rod 4 and the fixed base 3. The base 301 has a first torsion spring groove 34 around the pivot hole 36 near the hanging rod 4, and a second torsion spring groove 43 around the pivot shaft 42 of the hanging rod 4. One end of the torsion spring 8 is located in the first torsion spring groove 34, and the other end of the torsion spring 8 is located in the second torsion spring groove 43. The reset position of the hanging rod 4 can be either when the hanging rod 4 is retracted forward to the position where it does not protrude from the chair back, or when it is extended backward to its limit.

[0036] In this utility model, such as Figure 1 and Figure 4 As shown, the fixing base 3 includes a base 301 and a cover 302, which are fixedly connected. A mounting hole 31 is formed between the base 301 and the cover 302, and the cover 302 is located at the front of the base 301. The upper part of the base 301 is fixedly connected to the lower end of the connector 2, and the upper part of the cover 302 is fixed to the chair back frame. The hanging rod 4 is arc-shaped; when the hanging rod 4 is retracted forward to abut against the entire chair back frame, it is hidden.

[0037] like Figures 4 to 6As shown, the groove 32 is disposed on the base 301, and the first insertion port 33 is located on the front or rear side of the base 301. The side of the base 301 with the first insertion port 33 also has a mounting groove 35. The first insertion port 33 is located within the mounting groove 35, and the plug 6 is installed within the mounting groove 35. The insertion end 61 of the plug 6 can pass through the first insertion port 33 and be inserted into the groove 32 to engage with the locking member 5. For aesthetic purposes, when the insertion end 61 of the plug 6 is not engaged with the locking member 5, the side of the plug 6 away from the insertion end 61 is flush with the outer surface of the mounting groove 35; pressing the plug 6 can cause the insertion end 61 to engage with the locking member 5. Preferably, a second elastic member 9 for resetting the plug 6 is provided between the plug 6 and the bottom of the mounting groove 35. Specifically, the second elastic member 9 is a spring.

[0038] In this invention, the headrest component includes a support frame 11, a headrest frame 12, and a connector 2. The connector 2 connects the headrest component to the fixing base 3. The rear end of the support frame 11 is connected to the upper part of the connector 2, and the front end of the support frame 11 is connected to the headrest frame 12. The outer surface of the headrest frame 12 is covered with a mesh fabric or similar material.

[0039] In this utility model, such as Figures 1 to 2 As shown, the rear end of the support frame 11 is hinged to the upper part of the connector 2, and the headrest frame 12 is height-adjustable and rotatably connected to the support frame 11. Specifically, as... Figures 1 to 3 As shown, a fixed plate 121 is vertically arranged between the upper and lower frame edges of the headrest frame 12. A mounting plate 14 is fixedly installed on the front of the fixed plate 121. A connecting shaft 13 is hinged to the front end of the support member 11. The connecting shaft 13 is clamped between the fixed plate 121 and the mounting plate 14 and can move up and down between the fixed plate 121 and the mounting plate 14, thereby realizing that the headrest frame 12 can be lifted and lowered and is rotatably connected to the support frame 11. In order to prevent the connecting shaft 13 from moving left and right or tilting, several rows of vertical guide holes 141 are opened on the mounting plate 14. Several rows of protrusions 131 that are adapted to the guide holes 141 are provided on the front of the connecting shaft 13. When the connecting shaft 13 is clamped between the fixed plate 121 and the mounting plate 14, the protrusions 131 of the connecting shaft 13 are located in the guide holes 141 of the mounting port 14 and can move up and down along the guide holes 141. To increase the friction between the connecting shaft 13 and the fixing plate 121, the fixing plate 121 is provided with several vertical ribs 1211 protruding forward, and the front surface of the ribs 1211 is provided with wave grooves 1212. More preferably, the rear surface of the connecting shaft 13 is provided with elastic elements such as rubber strips, so that the connecting shaft 13 can be fixed in relative position with the fixing plate 121 by friction, thereby fixing the position of the headrest frame 12. When it is necessary to adjust the height of the headrest frame 12, the headrest frame 12 can be pulled up or down; when it is necessary to adjust the angle of the headrest frame 12, the headrest frame 12 can be rotated back and forth.
