[0005] By adopting the above technical solution, after the chair back is rotated and adjusted, the rotating arm is rotated, and the limiting disc will rotate relative to the end of the rotating arm. At this time, the elastic part can be separated from the notch and then embedded in another notch. The pressing effect of the elastic part limits the rotation angle, and the predetermined angle can be maintained during use. When a larger force is applied, the elastic part will be separated from the notch, which is convenient for overall adjustment.

[0006] Preferably, the notch is an open structure toward the outside, the end of the rotating arm has a rotating ring which is sleeved and rotatably connected to the fixed block, the limiting disc is located inside the rotating ring, and the elastic member is arranged on the inner wall of the rotating ring.

[0008] Preferably, the other end of the rotating arm has a sliding block which is positionably slidably connected to the support plate, and the support plate has a slideway for the sliding block to slide in the horizontal reverse direction.

[0009] Preferably, the inner wall of one end of the slideway is wavy, the sliding block has a second elastic ring embedded in a recessed portion of the inner wall, and the outer wall of the sliding block fits the non-wavy inner wall.

[0010] In summary, the present application includes at least one of the following beneficial technical effects: after the chair back is rotated and adjusted, by rotating the rotating arm, the limiting disc will rotate relative to the end of the rotating arm. At this time, the elastic part can be disengaged from the notch and then embedded in another notch.

DETAILED DESCRIPTION

[0016] The present application is further described in detail below in conjunction with the accompanying drawings.

[0017] The present application discloses a multi-position adjustable chair armrest structure. Figure 1 , Figure 2 , including a fixed block 100 for connecting the main body, a rotating arm 110 is positionably connected to the fixed block 100, one end of the rotating arm 110 has a rotating ring 111 rotatably connected to the fixed block 100, a limiting disk 112 is fixedly connected to the fixed block 100, the limiting disk 112 is located in the rotating ring 111, the limiting disk 112 is fixed to the fixed block 100 by bolts, and the rotating ring 111 and the limiting disk 112 rotate relative to each other.

[0018] The limiting disc 112 has a plurality of notches 113 along the circumference. The notches 113 are open toward the outside and concave inside, with arc transitions at both ends of the notches 113. An elastic member is provided on the inner wall of the rotating ring 111 for embedding into the notches 113 to limit the rotation angle of the limiting disc 112.

[0019] Specifically, the elastic member is a first elastic ring 114, which is in an arc shape as a whole, and its two ends are fixedly connected to the inner wall of the rotating ring 111, and the connection position is located in the middle position of the rotating ring 111 along the axial direction to facilitate deformation. The middle part of the first elastic circle is an outwardly convex arc shape, which is used to be embedded in the notch 113.

[0020] Under the action of external force, the first elastic ring 114 will be deformed, thereby disengaging from the previous notch 113, and at this time, it is convenient for rotation, and there is a gap between the outer side of the limiting disc 112 and the rotating ring 111 for the deformed first elastic ring 114 to pass through. In this way, after rotating to a certain angle, the first elastic ring 114 will remain embedded in the notch 113, providing a limit for the rotation angle. In this embodiment, in order to maintain the elasticity of the first elastic ring 114 itself and facilitate its return to its original state, an auxiliary spring 115 is also fixedly connected between the rotating ring 111 and the inner wall of the first elastic ring 114, so as to help the first elastic ring 114 have good resilience.

[0021] Reference Figure 3 At the same time, a limit block 120 is provided on the inner side of the rotating ring 111, and a rotating groove 121 is provided on the fixed block 100 for the limit block 120 to be embedded in and rotated in the circumferential direction. A thrust block 122 is provided in the rotating groove 121 for contacting the limit block 120 to limit the rotation angle of the rotating arm 110.

[0022] Reference Figure 1 , Figure 4 A support plate 130 for supporting the arm is provided at the other end of the movable arm 110. A slide 131 is provided in the middle of the support plate 130. A sliding block 132 is slidably connected in the slide 131. The sliding block 132 is fixedly connected to the rotating arm 110 by bolts, so that after adjusting the rotation angle of the armrest, the position of the support plate 130 can also be adjusted to improve the user experience.

[0023] Specifically, the inner wall of one end of the slideway 131 is wavy, and the other end is a plane. One end of the sliding block 132 has a second elastic ring 133 embedded in the inner wall depression, and the outer wall of the other end of the sliding block 132 is in contact with the non-wavy inner wall. The plane is used to guide, and the second elastic ring 133 will be limited in the horizontal sliding direction by the wavy inner wall, thereby fixing the position of the support plate 130.

[0024] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
