[0022] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0023] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0024] Reference Figure 1 and Figure 2 as well as Figure 3 As shown, the armrests of an office chair are used to protect and support office workers, which can greatly improve the safety and comfort of office workers. The armrests of most existing office chairs are fixed one-piece structures. When the armrests of the office chair need to be adjusted or the office chair is stored, the fixed one-piece armrests cannot meet the above requirements, and in some special scenarios, the armrests do not have an extension effect, resulting in a significant reduction in practicality. In order to solve such problems, an office chair with a rotating armrest structure is proposed, including an armrest frame 1, one side of the armrest frame 1 is rotatably provided with an office chair body 12 for installing the armrest frame 1, a limiting member for limiting the rotation of the armrest frame 1 is provided between the armrest frame 1 and the office chair body 12, and a groove 11 is also provided in the armrest frame 1, and an extension member 2 is provided in the groove 11, and the extension member 2 includes an extended armrest 21 rotatably arranged in the groove 11, A first rotating shaft 211 is rotatably provided between the extended armrest 21 and the groove 11, and the extended armrest 21 is rotated along the opening direction of the groove 11 to extend to one side of the armrest frame 1 for extending the length of the armrest frame 1, and a fixing member 3 for fixing the extended armrest 21 is provided on one side of the extended armrest 21. By setting the rotational connection between the armrest frame 1 and the office chair body 12, the armrest frame 1 can be rotated for storage when the office chair body 12 needs to be stored, and the setting of the limiting member can ensure the stability of the setting of the armrest frame 1 to a certain extent. By setting the extension member 2, when the length of the armrest frame 1 is not enough, the length of the armrest frame 1 can be increased by rotating and extending the extended armrest 21, which can greatly improve the practicality of the entire armrest structure, and the setting of the fixing member 3 can also be used to fix and limit the extended armrest 21 to ensure its rotation stability.

[0025] It should be noted that the armrest frame 1 is rotated along the office chair body 12, and its normal setting state is a horizontal setting state. When it needs to be stored and rotated, the armrest frame 1 rotates clockwise and is attached to one side of the office chair body 12; and the stability of the horizontal setting state of the armrest frame 1 can be ensured by the setting of the above-mentioned limit member.

[0026] Furthermore, the specific structure of the above-mentioned limit member is as follows: the limit member includes a second rotating shaft 13 arranged in the armrest frame 1, one end of the second rotating shaft 13 extends outwardly into the office chair body 12, and the outer periphery of the second rotating shaft 13 protrudes outward to form a card block 131, and a rotating groove for the second rotating shaft 13 to be inserted is opened in the office chair body 12, and a card slot 121 for the card block 131 to slide is opened outward on the side of the rotating groove close to the card block 131; the second rotating shaft 13 is rotated to drive the card block 131 to rotate at a small angle in the card slot 121, so as to ensure that the second rotating shaft 13 has a certain angle limitation, which also ensures that when the armrest frame 1 is set to the maximum rotation value in the horizontal state, it cannot continue to rotate counterclockwise, which also ensures the stability of the horizontal setting of the armrest frame 1.

[0027] Additionally, when the armrest frame 1 is in the vertical accommodation state, the clamping groove 121 can also prevent the clamping block 131 and the second rotating shaft 13 from sliding over the stroke, thereby ensuring an overall limiting effect.

[0028] It should also be noted that the angle of the above-mentioned slot 121 is 120°, and the top side wall of the slot 121 is set in a vertical state. The top side wall mentioned here is in a vertical state. It means that when the handrail frame 1 is set horizontally, one side of the block 131 is attached to the top side wall and cannot be rotated. Figure 3 shown.

[0029] In addition, the specific structure of the above-mentioned fixing member 3 is as follows: the fixing member 3 includes a limiting slide plate 31 which is horizontally slidably arranged on the top of the handrail frame 1, and the limiting slide plate 31 slides close to or away from the groove 11 to fix and limit the top of the extended handrail 21; the limiting slide plate 31 can slide to the upper side of the groove 11 by horizontally sliding. When the limiting slide plate 31 slides to the upper side of the groove 11, the extended handrail 21 cannot be rotated to the outside by rotation, thereby achieving the purpose of fixing and limiting the extended handrail 21.

[0030] It is worth mentioning that when the above-mentioned limiting slide plate 31 is on the side away from the groove 11, the extended armrest 21 in the groove 11 can be rotated out of the groove 11 and rotated 180° to one side of the armrest frame 1 to extend the armrest frame 1. In order to make the extended armrest 21 better support and protect the arms of the seated person, in this embodiment, a protective pad 22 for protecting the arms of the seated person is provided on a side surface of the bottom of the extended armrest 21 close to the groove 11; the provision of the protective pad 22 can achieve the purpose of further protecting the seated person.

[0031] Furthermore, in order to facilitate the sitting person to rotate out the above-mentioned extended armrest 21, in this embodiment, a pull groove 212 is provided on the top of the extended armrest 21 for convenient grasping of the extended armrest 21; through the setting of the pull groove 212, the hand of the sitting person can be inserted into the pull groove 212 in an orderly manner, and the extended armrest 21 can be pulled out conveniently.

[0032] It should be noted that in order to make the handrail frame 1 more stable, in the present embodiment, buffer pads 14 for buffering external impacts are respectively provided on both sides of the handrail frame 1; the provision of the buffer pads 14 can ensure that the handrail frame 1 is more stable when subjected to external impacts.

[0033] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention is not limited to the embodiments described in the specific implementation manner. Any other implementation manners derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of protection of the present invention.
