AI Technical Summary
Traditional standing swan chairs have a fixed height, making it inconvenient to adjust according to the user's height or usage scenario. They also require being fully lifted or dragged when moved, which is not convenient.
The chair height is adjusted by using a rotating worm gear to drive a worm wheel and a threaded rod, which in turn raises the threaded cylinder. Combined with the limiting structure of the casters, this ensures the stability and safety of the chair during movement.
It enables flexible adjustment of chair height, reduces pressure on the lower back, improves sitting comfort, and maintains stability and safety during movement, thereby enhancing the user experience and work efficiency.

[0038] With reference to Figure 1 , Figure 2 and Figure 3 , the present application provides an embodiment: a novel vertical swan chair, comprising a fixed seat 3 and a chair 4, the lower end of the chair 4 being provided with a lifting mechanism 1, and the outer wall of the fixed seat 3 being provided with a moving mechanism 2, the lifting mechanism 1 comprising a support rod 101, the lower end of the outer wall of the support rod 101 being fixedly connected to the inner wall of the fixed seat 3, a hollow groove 102 being formed in the upper end of the support rod 101, a threaded rod 103 being rotatably connected to the inner bottom surface of the hollow groove 102, a threaded cylinder 104 being sleeved on the outer wall of the threaded rod 103, limiting blocks 105 being fixedly connected to the two sides of the outer wall of the threaded cylinder 104, a worm gear 106 being fixedly connected to the lower end of the outer wall of the threaded rod 103, and a worm 107 being arranged at the lower part of the rear end of the inner wall of the hollow groove 102;
[0039] When the worm 107 is rotated, the worm gear 106 is rotated, the threaded rod 103 is rotated, the threaded cylinder 104 is moved upward, and thus the chair 4 is pushed to be lifted, the user can easily adjust the height of the chair 4, the feet can be placed flat on the ground, the knees are kept at 90 degrees bending, the waist and back pressure is effectively reduced, different height and body type users can be adapted, and the sitting comfort is improved.
[0040] With reference to Figure 4 , Figure 5 , Figure 6 andFigure 7 The outer wall of the fixed seat 3 is uniformly and fixedly connected with a plurality of support blocks 201. The lower part of the plurality of support blocks 201 away from the center of the fixed seat 3 is provided with a cavity 202. The side of the plurality of cavities 202 away from the center of the fixed seat 3 is provided with a first sliding groove 203. The side of the plurality of cavities 202 close to the center of the fixed seat 3 is provided with a second sliding groove 204. The inner wall of the plurality of first sliding grooves 203 is provided with a first sliding block 205. The inner wall of the plurality of second sliding grooves 204 is provided with a second sliding block 206. The side of the plurality of support blocks 201 away from the center of the fixed seat 3 is fixedly connected with a plurality of damping rods 209. The outer wall of the plurality of damping rods 209 is sleeved with a spring 210. The side of the plurality of damping rods 209 away from the center of the fixed seat 3 is fixedly connected with a connecting block 207. The two ends of the side of the plurality of connecting blocks 207 close to the center of the fixed seat 3 are fixedly connected with a protrusion 208. When the chair 4 is moved, the connecting block 207 is pulled, the upper end protrusion 208 of the connecting block 207 is disengaged from the first sliding block 205, the universal wheel 5 is lowered to the lowest position, and the chair 4 can stably contact the ground during movement. Then, the lower end protrusion 208 is engaged with the first sliding block 205 to prevent the universal wheel 5 from retracting during movement, thereby effectively limiting the movement of the chair 4 and making the movement of the chair 4 more convenient.
