DETAILED DESCRIPTION
[0020] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0021] Example:
[0022] Reference Figure 1 to Figure 3 The device is an adjustable dining chair, comprising a seat frame 1 and a seat board 2. The seat frame 1 is located on one side of the seat board 2 and is detachably connected to the seat board 2. The bottom of the seat frame 1 is fixedly connected to the bottom of the seat board 2 by bolts and nuts. A cushion 21 is provided on the seat board 2. An adjustment frame 3 is provided below the seat board 2. An adjustment assembly for adjusting the height of the seat board 2 is provided on the adjustment frame 3. The adjustment assembly comprises a screw 5, a worm wheel 6 with a thread on the inner wall, and a worm 7. The screw 5 is rotatably mounted on the bottom of the seat board 2 through a bearing. A threaded sleeve 8 is fixed on the adjustment frame 3. The other end of the screw 5 is vertically downwardly threaded in the threaded sleeve 8. The worm wheel 6 is coaxial with the threaded sleeve 8 and rotatably mounted on the threaded sleeve 8. A bearing is provided between the worm wheel 6 and the threaded sleeve 8 to realize rotatable mounting. The inner wall of the worm wheel 6 is threadedly connected to the screw 5. The worm 7 is rotatably mounted on the adjustment frame 3. The worm 7 and the worm wheel 6 are meshed with each other. A rotating handle 9 is provided at the end of the worm 7 extending out of the adjustment frame 3. This arrangement can effectively drive the meshing worm wheel 6 to rotate through the rotation of the worm 7. When the worm wheel 6 rotates, it will further drive the screw 5 to move up and down in the threaded sleeve 8, so that the height of the seat plate 2 relative to the adjustment frame 3 can be adjusted.
[0023] like Figure 1 and Figure 3As shown, the bottom of the adjustment frame 3 is provided with a base 4, the adjustment frame 3 is horizontally slidably arranged in the base 4, the base 4 is provided with a slide groove 10, and a horizontal slide rod 11 is arranged in the slide groove 10. The bottom of the adjustment frame 3 is slidably sleeved on the slide rod 11, and the adjustment frame 3 is provided with a fixing component for limiting the sliding of the adjustment frame 3, the fixing component includes a rotating shaft 12, a pedal 13, a fixing rod 14 and a pin 15, the rotating shaft 12 is rotatably mounted on the side wall of the adjustment frame 3, the pedal 13 is fixedly mounted on one side of the rotating shaft 12 and extends outward, and the fixing rod 14 is fixedly mounted On the other side of the rotating shaft 12, the pin rod 15 is rotatably mounted on the end of the fixing rod 14 away from the rotating shaft 12. A fixing hole 16 is opened at the bottom of the adjusting frame 3, and a plurality of connecting holes 17 are axially opened on the sliding rod 11. The bottom of the pin rod 15 slides through the fixing hole 16 and extends into one of the connecting holes 17. A protrusion 18 is provided on the side wall of the adjusting frame 3 and below the pedal 13. A return spring 19 is fixed between the protrusion 18 and the pedal 13. A plurality of guide rods 20 are also provided at the bottom of the seat plate 2. The plurality of guide rods 20 extend vertically downward and slide into the adjusting frame 3. This arrangement can effectively enable the rotating shaft 12 to drive the fixing rod 14 to rotate upward by stepping on the pedal 13. At this time, the pin rod 15 located at the end of the fixing rod 14 will slide out of one of the connecting holes 17, and the position of the entire seat on the base 4 can be adjusted by further sliding the adjustment frame 3 on the slide rod 11. When it is necessary to fix, the pedal 13 is released, and the pedal 13 is rebounded by the return spring 19. As the adjustment frame 3 slides on the connecting rod, the pin rod 15 will re-enter one of the connecting holes 17 for positioning.
[0024] Working principle:
[0025] When in use, the user can adjust the height of the seat plate 2 according to his / her height, specifically by rotating the worm 7 to drive the meshing worm wheel 6 to rotate, and when the worm wheel 6 rotates, it will further drive the screw 5 to move up and down in the threaded sleeve 8, so that the height of the seat plate 2 relative to the adjustment frame 3 can be adjusted. When the distance between multiple users is too close, the user can step on the pedal 13 to make the rotating shaft 12 drive the fixing rod 14 to rotate upward, and then the pin rod 15 at the end of the fixing rod 14 will slide out of one of the connecting holes 17, and further adjust the position of the seat as a whole on the base 4 by sliding the adjusting frame 3 on the sliding rod 11. When it is necessary to fix, release the pedal 13, and the pedal 13 will rebound through the reset spring 19. As the adjusting frame 3 slides on the connecting rod, the pin rod 15 will re-enter one of the connecting holes 17 for positioning.
[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
