[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figure 1 As shown, a multi-dimensional adjustable support device for an office chair includes a support base 1, a seat 2 fixedly connected to the upper surface of the support base 1, an adjustment component 4 fixedly connected to the right side of the support base 1, a chair back 3 fixedly connected to the left side of the upper part of the adjustment component 4 and the chair back 3 being located above the seat 2, and a support component 5 fixedly connected to the left side of the upper part of the adjustment component 4, the left side of the support component 5 overlapping the right side of the middle part of the chair back 3.

[0019] First, the height of the chair back 3 can be adjusted according to the user's needs under the action of the adjustment component 4. Then, under the action of the support component 5, the support strength of the support mesh in the middle of the chair back 3 can be adjusted, thereby improving the user's comfort.

[0020] like Figure 2 As shown, the adjustment assembly 4 includes a U-shaped plate 41. The left side of the U-shaped plate 41 is fixedly connected to the right side of the upper part of the support base 1. A support plate 42 is slidably connected to the inner wall of the U-shaped plate 41. The left side of the middle part of the support plate 42 is fixedly connected to the right side of the lower part of the chair back 3. An adjustment seat 43 is fixedly connected to the left side of the lower part of the support plate 42 and is located below the seat 2. A threaded rod 44 is threadedly connected to the inner cavity of the adjustment seat 43. The outer walls of the upper and lower parts of the threaded rod 44 are rotatably connected to the inner cavities of the upper and lower parts of the support base 1, respectively. An anti-slip sleeve 45 is fixedly connected to the outer wall of the threaded rod 44 and is located below the adjustment seat 43. By rotating the anti-slip sleeve 45, the threaded rod 44 can be rotated, thereby allowing the adjusting seat 43 to move downward under the action of the guide rod 46. Through the action of the adjusting seat 43, the support plate 42 can drive the backrest 3 to move downward, so that the lumbar support height can be adjusted according to the user's needs during use.

[0021] like Figure 3 As shown, guide rods 46 are slidably connected to the inner cavities of the front and rear parts of the adjusting seat 43, and the two guide rods 46 are located on the front and rear sides of the threaded rod 44 respectively. The upper and lower sides of the two guide rods 46 are fixedly connected to the inner wall of the support base 1 respectively. Through the action of the guide rod 46 and the U-shaped plate 41, the adjusting seat 43 and the support plate 42 can move up and down steadily, thereby playing a guiding and supporting role.

[0022] An arc-shaped support rod 421 is fixedly connected to the left side of the upper part of the support plate 42, and the left side of the arc-shaped support rod 421 is fixedly connected to the right side of the chair back 3. The curved support rod 421 increases the support strength of the chair back 3, thereby ensuring safety during use.

[0023] like Figure 4 As shown, two L-shaped guide rods 56 are fixedly connected to the upper surface of the fixing block 52. The outer walls of the upper part of the two L-shaped guide rods 56 are respectively inserted into the inner cavity of the arc-shaped support rod 421 and the support plate 42. The L-shaped guide rod 56 enables the arc-shaped support plate 51 to move left and right between the support plate 42 and the chair back 3, thereby playing a guiding role.

A fixing block 52 is fixedly connected to the right side of the arc-shaped support plate 51. A sleeve rod 53 is rotatably connected to the right side of the fixing block 52. A threaded rod 54 is threadedly connected to the inner wall of the sleeve rod 53. The right side of the threaded rod 54 is fixedly connected to the left side of the support plate 42. Operating rods 55 are fixedly connected to both the upper and lower sides of the outer wall of the sleeve rod 53. By rotating the operating lever 55, the sleeve lever 53 can rotate to the left under the action of the threaded rod 54, thereby allowing the arc-shaped support plate 51 to move to the left under the action of the L-shaped guide rod 56, thus adjusting the support curvature of the waist and improving the user's comfort.

[0025] The working principle of this utility model is as follows: First, by rotating the anti-slip sleeve 45, the threaded rod 44 can rotate, thereby allowing the adjusting seat 43 to move downward under the action of the guide rod 46. Through the action of the adjusting seat 43, the support plate 42 can drive the backrest 3 to move downward, thereby adjusting the lumbar support height according to the user's needs. Then, by rotating the operating lever 55, the sleeve 53 can rotate to the left under the action of the threaded rod 54, thereby allowing the arc-shaped support plate 51 to move to the left under the action of the L-shaped guide rod 56, thereby adjusting the lumbar support curvature and improving the user's comfort.
