It provides support for all parts of the body, reducing fatigue and health risks caused by prolonged sitting. The support seat 5 includes a support rod and its lower end set on a five-claw foot. The claw ends of the five-claw foot are equipped with casters. The support rod can be a gas rod. The upper end of the support rod is fixedly connected to the middle of the lower surface of the seat 1. The position of the mesh chair can be easily adjusted by rotating the casters. It also includes a folding mechanism 9. The retractable mechanism 9 includes a rotating plate 91, gears 92, and rack plates 93. The rotating plates 91 are slidably connected to the interior of the bracket 6. The sliding columns on the outer arc surface of the support rod 7 are slidably connected to the recessed grooves on the surface of the rotating plates 91. Gears 92 are located in the middle of each rotating plate 91. Rack plates 93 are respectively disposed on the top wall of the bracket 6, and each rack plate 93 meshes with an adjacent gear 92. During use of the foot pedal 8, the rotating plates 91 are fixed in position within the bracket 6. The meshing connection between the gears 92 and rack plates 93 restricts the rotation of the gears 92 and rotating plates 91. The angle of the rotating plate 91 is fixed, and under the support of the rotating plate 91, the angle between the support rod 7 and the bracket 6 is fixed, maintaining the normal use of the foot pedal 8. When the foot pedal 8 is not needed, simply push the rotating plate 91 down inside the bracket 6. Through the meshing connection of the gear 92 and the rack plate 93, the gear 92 drives the rotating plate 91 to rotate clockwise. The sliding column on the outer arc surface of the support rod 7 slides in the clearance groove on the surface of the rotating plate 91. The rotating plate 91 applies force to the support rod 7, pushing the support rod 7 to rotate clockwise, thus retracting the foot pedal 8. Figure 6As shown, the top wall of the bracket 6 is fixedly connected to a protective cover by bolts. The upper end of the protective cover is an open structure. The gear 92 and the rack plate 93 are both located inside the protective cover to avoid the influence of external dust on the transmission components. The rotating plate 91 consists of two rotating plates and a rotating sleeve between the left ends of the two rotating plates. The gear 92 is set on the outer arc surface of the rotating sleeve. The protective cover is located between the two rotating plates of the rotating plate 91. Both the left and right ends of the protective cover are provided with clearance through holes. The inner wall of the clearance through hole and the outer arc surface of the rotating sleeve of the rotating plate 91 are provided with elastic rubber pads. Through the deformation of the elastic rubber pads, the rotating plate 91 can move normally while avoiding the influence of external dust on the transmission components. The closing mechanism 9 also includes a limiting slide groove 94 and a slide tube 97. The limiting slide groove 94 is respectively set on the opposite inner side of the two brackets 6. The slide tube 97 is slidably connected inside the limiting slide groove 94. The rotating plate 91 is respectively set on the outer arc surface of the slide tube 97. The slide tube 97 slides in the limiting slide groove 94, providing sliding support and limiting the sliding range for the rotating plate 91. During the rotation of the rotating plate 91, the slide tube 97 rotates in the limiting slide groove 94. The central axis of the gear 92 is collinear with the central axis of the slide tube 97, ensuring the normal meshing connection between the gear 92 and the rack plate 93. The closing mechanism 9 also includes a pin 95 and a hole 96. The holes 96 are respectively set on the opposite surfaces of the two supports 6. The elastically limited pins 95 are slidably connected to the inside of the slide tube 97. The pins 95 and the holes 96 are installed together. When the slide tube 97 contacts the bottom wall of the limiting slide groove 94, the pins 95 and the lower hole 96 are horizontally overlapped. When the slide tube 97 contacts the top wall of the limiting slide groove 94, the pins 95 and the upper hole 96 are horizontally overlapped. The vertical position of the slide tube 97 is limited by the insertion of the pins 95 and the holes 96. Each end of the insertion post 95 is equipped with an adjusting sleeve 10. The adjusting sleeve 10 is slidably connected laterally to the sliding groove on the outer arc surface of the slide tube 97. A spring 11 is provided between the adjusting sleeve 10 and the limiting ring on the outer arc surface of the slide tube 97. The spring 11 is movably sleeved on the outer arc surface of the slide tube 97. The elastic force of the spring 11 provides elastic limiting for the adjusting sleeve 10. By pushing the adjusting sleeve 10 to move laterally, the insertion post 95 is pulled away from the insertion hole 96. When the adjusting sleeve 10 is released, under the action of the elastic force of the spring 11, The insertion post 95 is inserted into the horizontally overlapping insertion hole 96. The ends of the spring 11 are fixedly connected to the adjusting sleeve 10 and the slide tube 97 respectively by connecting bolts. The connecting bolts are rotated periodically to disassemble, replace or maintain the spring 11 to avoid corrosion and aging affecting the normal operation of the spring 11. The adjusting sleeve 10 is movably sleeved on the outer arc surface of the insertion post 95. The sliding plate of the inner arc surface of the adjusting sleeve 10 is laterally slidably connected to the sliding groove of the outer arc surface of the slide tube 97. The sliding plate of the adjusting sleeve 10 is fixedly connected to the end of the insertion post 95. Rotating sleeves 12 are rotatably connected in the rotating grooves on the outer arc surface of the adjusting sleeve 10. During the process of the rotating plate 91 driving the slide tube 97 and the adjusting sleeve 10 to rotate, the relative rotation between the rotating sleeve 12 and the adjusting sleeve 10 facilitates the gripping of personnel. A connecting tube 13 is fixedly sleeved between the outer arc surfaces of the two slide tubes 97. The limiting bolts pass through the round hole on the surface of the connecting tube 13 and the insertion hole on the surface of the slide tube 97 respectively and are threaded with the nut to connect the two slide tubes 97, so that the two slide tubes 97 rotate synchronously. Each support 6 has an upper support column 15 at its upper end, which is fixedly connected to the lower surface of the seat 1. A lower support plate 14 is provided between the lower ends of the two supports 6. The lower support plate 14 is rotatably connected to the outer arc surface of the support column of the support base 5 to provide support for the installation of the support 6.

[0016] The working principle of the reclining, fully-fitting mesh chair with footrest provided by this utility model is as follows: In use, the user sits on the upper surface of the seat 1, with their back against the backrest 2. The headrest 3 provides support for the user's head and neck, the lumbar support 4 provides support for the user's waist, the armrests at both ends of the seat 1 provide support for the user's arms, and the footrest 8 provides support for the user's feet, facilitating reclining and providing support for various parts of the body, reducing fatigue and health risks caused by prolonged sitting. During the use of the footrest 8, the insertion post 95 is inserted into the upper insertion hole 96, restricting the movement of the rotating plate 91 inside the bracket 6. The meshing connection of the gear 92 and the rack plate 93 restricts the rotation of the gear 92 and the rotating plate 91. The angle of the rotating plate 91 is fixed. Under the support of the rotating plate 91, the angle between the support rod 7 and the bracket 6 is fixed, maintaining the normal use of the footrest 8. When the foot pedal 8 needs to be used, the operator only needs to overcome the elastic force of the spring 11, push the two adjusting sleeves 10 closer together, pull the insert 95 away from the insertion hole 96, and then push the slide tube 97 to slide in the limiting slide groove 94, causing the rotating plate 91 to slide in the bracket 6. Through the meshing connection of the gear 92 and the rack plate 93, the gear 92 drives the rotating plate 91 to rotate clockwise. The sliding column on the outer arc surface of the support rod 7 slides in the clearance slide groove on the surface of the rotating plate 91. The rotating plate 91 applies force to the support rod 7, pushing the support rod 7 to rotate clockwise. When the slide tube 97 contacts the bottom wall of the limiting slide groove 94, the insert 95 and the lower insertion hole 96 are horizontally overlapped. Under the elastic force of the spring 11, the insert 95 is inserted into the lower insertion hole 96, restricting the rotation of the rotating plate 91. At this time, the foot pedal 8 is folded to the lower side of the chair back 2, reducing the space occupied by the overall device.

[0017] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
