[0028] See also Figure 1-Figure 7 A leisure office chair comprises a chair body 1, a retractable leg support 2 is installed on the chair body 1 corresponding to the position of the human leg, a waist pad 4 is installed on the chair body 1 corresponding to the position of the human waist, and the waist pad 4 is reinforced by a reinforcing rod 3;

[0029] Specifically, the lumbar pad 4 is installed behind the backrest of the chair body 1 corresponding to the human waist, one end of the reinforcing rod 3 is connected to the frame of the chair body 1, and the other end of the reinforcing rod 3 is fixedly connected to the back of the lumbar pad 4. By installing the lumbar pad 4 behind the backrest, the comfort of leaning can be improved, and the reinforcing rod 3 is used to support the lumbar pad 4 and the backrest, thereby improving the overall strength and further improving the leaning stability;

[0030] Specifically, Figure 2 As shown, the retractable leg rest 2 includes a retractable frame 21 and a support plate 22, the retractable frame 21 is fixedly mounted on the bottom of the seat cushion of the chair body 1, and the support plate 22 is mounted on the movable end of the retractable frame 21 and can be turned up and down and locked by a fastener 5;

[0031] The turning axis of the support plate 22 is perpendicular to the length direction of the human leg. When the upper end surface of the support plate 22 is turned to a horizontal state, it can be locked by the fastener 5 to support the user's legs. When the leg support is not needed, the support plate 22 can be turned down for storage, and the support plate 22 can be driven forward or backward by the telescopic frame 21, which is convenient for users of different body shapes to use and easy to fold and store.

[0032] Furthermore, if Figure 4 As shown, the telescopic frame 21 includes a telescopic rod 211 and a cross bar 212. One end of the telescopic rod 211 is fixed to the bottom of the seat cushion of the chair body 1, and the other end of the telescopic rod 211 is a movable end and is fixedly connected to the middle of the cross bar 212. Both ends of the cross bar 212 are rotatably connected to the support plates 22. The symmetrical distribution of the two support plates 22 can support the user's legs at the same time.

[0033] Specifically, Figure 5As shown, the fastener 5 includes a base block 51, a limit block 52, and a rotating shaft 53. The base block 51 is mounted on the support plate 22, the limit block 52 is mounted on a side of the base block 51 close to the cross bar 212, and the rotating shaft 53 is mounted on a side of the limit block 52 away from the base block 51. The rotating shaft 53 is rotatably arranged inside the cross bar 212 and is limited by an elastic component, and the limit block 52 is clamped with the inner cavity opening of the cross bar 212;

[0034] It should be noted that the fastener 5 may also be directly a fastener such as a bolt or a positioning pin;

[0035] Furthermore, the elastic component includes a fixed ring 7, a stopper 8, a sliding ring 9, and a spring 10. The fixed ring 7 is installed in the inner cavity of the cross bar 212 near the opening. The end of the rotating shaft 53 away from the limit block 52 passes through the fixed ring 7 and is fixedly connected to the stopper 8. The sliding ring 9 is slidably mounted on the rotating shaft 53 and is located between the fixed ring 7 and the stopper 8. The spring 10 is mounted on the rotating shaft 53, and the two ends of the spring 10 are respectively fixedly connected to the fixed ring 7 and the sliding ring 9.

[0036] Furthermore, the inner diameters of the fixed ring 7 and the sliding ring 9 are consistent, the rotating shaft 53 passes through the inner holes of the fixed ring 7 and the sliding ring 9, and the outer circumference of the rotating shaft 53 is slidably connected to the inner walls of the fixed ring 7 and the sliding ring 9 and is rotatable.

[0037] Furthermore, if Figure 5 and Figure 7 As shown, the end surface of the cross bar 212 is provided with a limiting groove 6 communicating with its inner cavity, and the outer diameter of the limiting block 52 is larger than the inner diameter of the cross bar 212 and is adapted and clamped with the limiting groove 6;

[0038] Furthermore, if Figure 7 As shown, the limit block 52 is in the shape of a regular quadrangular prism, and the limit groove 6 is a regular quadrangular prism matched with the limit block 52. The regular quadrangular prism design makes it difficult for the base block 51 and the support plate 22 to rotate when the limit block 52 is engaged with the limit groove 6, so that it is convenient to support the user's legs; other multi-prism structures can also be used;

[0039] When the user needs to support the legs, the user only needs to extend the telescopic rod 211 to move the cross bar 212 to the front of the seat cushion of the chair body 1, then fix the extension length of the telescopic rod 211, and then pull the support plate 22 to both sides of the chair body 1, the support plate 22 drives the base block 51 and the limit block 52 to move outward, and the rotating shaft 53 drives the stop block 8 to move to the outside of the cross bar 212, the stop block 8 contacts the sliding ring 9 and drives the sliding ring 9 to move toward the fixed ring 7, the distance between the fixed ring 7 and the sliding ring 9 is gradually shortened, the spring 10 is compressed and deformed, and the limit block 52 is disengaged from the limit groove 6 at this time, the support plate 22 can be turned over, the rotating shaft 53 rotates along the inner holes of the fixed ring 7 and the sliding ring 9, and after rotating a certain angle, the support plate 22 is released, and under the elastic deformation of the spring 10, the rotating shaft 53 moves back and resets, and the limit block 52 is engaged with the limit groove 6 again, so that the support plate 22 can be limited, and the user's legs can be supported.

[0040] It should be noted that, in the specific embodiment, the limiting groove 6 and the limiting block 52 are mutually adapted regular quadrangular prism structures. Therefore, when actually adjusting and using, the support plate 22 in the initial state of the three o'clock direction can be rotated 180 degrees to turn the supporting surface upward, or the support plate 22 in the initial state of the six o'clock direction can be rotated 90 degrees to turn the supporting surface upward;

[0041] In summary, the leisure office chair proposed by the utility model, by adding a retractable leg rest 2 on the chair body 1, conveniently supports the user's legs, conforms to ergonomic design, and is beneficial to improving the user's sitting comfort. The retractable design of the retractable leg rest 2 makes it convenient to store the retractable leg rest 2 in the bottom space of the chair body 1, and the support plate 22 can also be flipped up and down, further improving the convenience of storage, making full use of the lower space of the chair, and the overall structural design is reasonable, taking into account ergonomics and space utilization, giving the user a better sitting experience.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
