Technical Field

[0001] This utility model relates to the field of seating technology, specifically to an easily adjustable seat. Background Technology

[0002] In educational settings, students spend a significant amount of time in their seats every day. Whether the seats are comfortable and at an appropriate height has a direct and profound impact on students' learning efficiency and physical health.

[0003] Based on the above, the inventors have discovered the following problems: In a school environment, students have varying heights, and the appropriate seat heights also differ. However, most existing school seats have a fixed height, and while a few can be adjusted by connecting bolts and pin holes, this adjustment method is extremely inconvenient. Every time a new semester begins and students change seats, they may need to adjust the seat height. Students need to find tools to remove the bolts, but these tools are hard to find in a school environment, making it impossible to adjust the seat height. Some students feel uncomfortable sitting or standing due to the uncomfortable seat height, making it difficult to concentrate on their studies and affecting their learning outcomes.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings to provide an adjustable seat with greater practical value. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figure 1 - Figure 4 The angle adjustment mechanism 104 also includes a transmission box 10402. One side of the transmission box 10402 is connected to one side of the base plate 10202. A worm gear 10405 is rotatably connected inside the transmission box 10402. The opposing ends of a pair of rotating shafts 10406 ​​extend through the transmission box 10402 and are respectively connected to the two central shafts on both sides of the worm gear 10405. A worm 10407 is rotatably connected inside the transmission box 10402 at the bottom end of the worm gear 10405. The worm 10407 meshes with the worm gear 10405. One end of the worm 10407 extends through the transmission box 10402 to the outside and is fitted with a second handwheel. A pair of buffer sleeves 101, made of rubber, are fitted at both ends of the base 100. The transmission box 10402 of the angle adjustment mechanism 104 is connected to... The base plate 10202 has a worm gear 10405 connected to a rotating shaft 10406, which transmits the rotation of the worm gear 10405 to the rotating shaft 10406, achieving synchronous adjustment of the angle of the back plate 10404 and ensuring consistent rotation of the back plate 10404. The worm 10407 in the transmission box 10402 meshes with the worm gear 10405. By rotating the second handwheel at one end of the worm 10407, the worm gear 10405 can be rotated, thereby adjusting the angle of the back plate 10404. The worm gear 10407 and worm gear 10405 mechanism has a self-locking characteristic, which can prevent the back plate 10404 from rotating on its own due to external force, ensuring stability after adjustment. The rubber buffer sleeves 101 at both ends of the base 100 can reduce the impact between the base 100 and the ground, protect the base 100 from damage, and reduce noise.

[0034] Specifically, the working principle of this adjustable seat is as follows: When using the adjustable seat, firstly, the seat is placed stably on the ground via the rubber buffer sleeves 101 at both ends of the base 100. The buffer sleeves 101 can reduce the impact between the base 100 and the ground, reduce noise, and protect the base 100. When the height of the seat plate 10202 needs to be adjusted, the user rotates the first handwheel 10210 on the bottom side of the support base 10201. The first handwheel 10210 drives the connected second bevel gear 10209 to rotate. Since the second bevel gear 10209 meshes with the first bevel gear 10207, the direction of power transmission changes, and the first bevel gear 10207 rotates accordingly, which in turn drives the screw 10204 to rotate at the center of the bottom of the support base 10201. Because the sleeve 10205 at the bottom of the adjusting seat 10203 is threadedly connected to the screw 10204, according to the principle of threaded transmission, the rotation of the screw 10204... The adjustment seat 10203 moves linearly up and down. It slides along the grooves 10206 on both sides of the support seat 10201, thus adjusting the height of the seat plate 10202. To adjust the angle of the back plate 10404, the user rotates the second handwheel outside the transmission box 10402. The second handwheel drives the worm gear 10407 to rotate. The worm gear 10407 meshes with the worm wheel 10405, causing the worm wheel 10405 to rotate accordingly. Due to the pair of rotating... The opposing ends of shaft 10406 ​​are connected to the central shafts on both sides of worm gear 10405. The rotation of worm gear 10405 is transmitted to shaft 10406. Shaft 10406 ​​rotates in mounting base 10401, driving connecting frame 10403 to rotate, thereby realizing synchronous adjustment of the angle of back plate 10404. At the same time, the self-locking characteristics of worm 10407 and worm gear 10405 mechanism ensure that back plate 10404 remains stable after adjustment and will not rotate on its own due to external force.
