Detailed Implementation

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1-4 As shown, an office chair with leg support function includes two support plates 1, which are fixed to the bottom surface of the seat body 2. A movable seat 3 is movably arranged between the two support plates 1. A foot pedal 4 is rotatably arranged inside the movable seat 3. Slots 5 are opened on the left and right sides of the outer wall of the movable seat 3. Several insertion holes 6 are opened on one side of the two support plates 1. Insert plates 7 are slidably inserted into the two slots 5 and slidably inserted into the insertion holes 6.

[0023] In use, the support plate 1 provides a solid foundation for the entire leg support structure. When the user needs to adjust the height of the foot pedal 4 to adapt to different leg support needs, the operation is very simple. Simply pull the two insert plates 7 out of the slots 5 and corresponding holes 6 respectively. At this time, the movable seat 3 and foot pedal 4 can move up and down between the two support plates 1. The user can adjust the foot pedal 4 to a suitable height according to their own comfort. After adjustment, accurately pass the two insert plates 7 through the corresponding holes 6 and insert them into the two slots 5 to quickly and effectively limit the movable seat 3 and foot pedal 4, thereby adjusting the leg support height. This not only allows users to flexibly adjust the leg support according to their individual needs, but also makes the entire assembly and disassembly process simple and quick. Through the combined use of the support plate 1, movable seat 3, foot pedal 4, slots 5, holes 6, and insert plates 7, the leg support height can be adjusted. At the same time, the simple structural design and convenient assembly and disassembly method reduce production and maintenance costs.

[0024] like Figures 1-3 As shown, a first magnet 8 is fixed inside the two slots 5 respectively, and a second magnet 9 is fixed inside the two insert plates 7 respectively. The two second magnets 9 are magnetically attracted to the two first magnets 8 respectively.

[0025] During use, when the user inserts the plug 7 through the socket 6 and into the slot 5, the first magnet 8 and the second magnet 9 will quickly generate a strong magnetic attraction force to fix the plug 7 in the slot 5. This can effectively prevent the plug 7 from falling off due to shaking or external force during use, thereby ensuring that the moving base 3 and the foot pedal 4 are always in a stable support state.

[0026] like Figures 1-4 As shown, the top surface of the foot pedal 4 has two fixing grooves 10, and a third magnet 11 is fixed in each of the two fixing grooves 10. A connecting rod 12 is fixed between the two support plates 1. Two mounting grooves 13 are opened on the front side of the connecting rod 12. A fourth magnet 14 is fixed in each of the two mounting grooves 13. The two fourth magnets 14 are magnetically attracted to the two third magnets 11 respectively. The top surface of the foot pedal 4 has a movable hole 15. An extension plate 16 is slidably arranged inside the movable hole 15. Slide grooves 17 are opened on the left and right sides of the inner wall of the movable hole 15. Slider blocks 18 are fixed on the left and right sides of the extension plate 16 respectively. The two sliders 18 are slidably arranged in the two slide grooves 17 respectively.

[0027] In use, when the user needs to fold up the foot pedal 4, first adjust the foot pedal 4 to its lowest position, then rotate the foot pedal 4 clockwise so that it rotates inside the movable seat 3. When the foot pedal 4 rotates to the vertical position, the connecting rod 12 can just block and fit the foot pedal 4. At this time, the third magnet 11 and the fourth magnet 14 will quickly generate a magnetic attraction, fixing the foot pedal 4 in the vertical position and completing the folding. This folding method not only saves office space and makes the office environment more tidy and orderly, but also is simple to operate without complicated steps, making it convenient for users to quickly unfold and use the foot pedal 4 when needed, greatly improving the practicality and convenience of the office chair. When the user feels that the length of the foot pedal 4 is insufficient to comfortably support the legs, the extension plate 16 can be moved. The extension plate 16 can slide within the movable hole 15, thereby extending the overall length of the foot pedal 4. While the extension plate 16 slides, the slider 18 will slide synchronously within the slide groove 17. The slide groove 17 plays a limiting role for the slider 18, effectively preventing the extension plate 16 from detaching from the foot pedal 4 during the sliding process, ensuring that the sliding of the extension plate 16 is stable and reliable, and providing the user with a safe and comfortable usage environment.

[0028] like Figures 1-4 As shown, a support plate 19 is fixed to the top surface of the foot pedal 4. The top surface of the support plate 19 is wavy. Armrests 20 are fixed to the left and right sides of the seat body 2, respectively. Rubber pads 21 are fixed to the top surfaces of the two armrests 20, and a headrest 22 is fixed to the top surface of the seat body 2.

[0029] During use, when the foot pedal 4 is moved to the top, the support plate 19 provides support for the user's legs. The wave-shaped design of the support plate 19 conforms to the curve of the human leg, which can evenly distribute leg pressure, effectively reduce leg fatigue, and provide a more comfortable and supportive effect. The armrest 20 provides a comfortable support platform for the user's arms, effectively reducing arm fatigue during long hours of office work, allowing the user to relax more during work or rest. The rubber pad 21, with its soft texture, further enhances arm comfort and also serves as a non-slip surface. The headrest 22 provides good support for the user's head and neck. When the user feels tired and needs to rest, they can lean on the headrest 22 to relieve neck pressure and relax their mind and body.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
