Description

Technical Field

[0001] This utility model relates to the field of seating technology, and in particular to a campus seat with adjustable angle. Background Technology

[0002] Campus seating, serving as elegant resting places, promoting communication, adding scenery, and beautifying educational spaces, is commonly seen in daily campus life. Many designs incorporate technological elements, offering not only practical functionality but also stimulating students' creativity and imagination. Furthermore, the designs are becoming increasingly diverse, with some featuring staggered heights, others incorporating mathematical elements, and still others drawing inspiration from traditional Chinese culture, making the seating an integral part of the campus culture. Adjustable backrests can be customized to meet students' needs, enhancing comfort. Modular designs allow for flexible combinations to accommodate various teaching requirements, such as group discussions and project collaborations. However, current campus seating designs are limited to fixed usage modes and lack necessary adjustment functions, significantly restricting students' flexibility in adapting to diverse scenarios. For example, students cannot adjust the backrest angle for personal comfort or level it for use as an additional seat or for reclining. This limitation clearly fails to fully address students' urgent need for multifunctional and adaptable seating, lacking applicability to more scenarios and requiring improvement.

[0023] Example 1

[0024] Please see Figure 1-5This utility model provides a technical solution: an angle-adjustable campus seat, including a back panel 1 and a seat 9. A second support column 12 is fixedly installed at the bottom of the seat 9, and a rubber protective sleeve 11 is fitted onto the bottom of the second support column 12 to better protect it and extend the service life of the seat. A U-shaped groove block 2 is fixedly installed on the back of the back panel 1. The two ends of the U-shaped groove block 2 have first circular slots. The two ends of the first support column 5 have second circular slots 23. Bolts 3 are installed inside the first circular slots 22 and the second circular slots 23, allowing the first support column 5 to rotate around the U-shaped groove block 2. Bolts 3 are fixedly installed on the inner side of the U-shaped groove block 2, and the first support column 5 is rotatably connected to the outer side of the bolts 3. A rotating shaft 13 is rotatably connected at the connection between the back panel 1 and the seat 9, and a rotating shaft 13 is fixedly installed on the outer side of the rotating shaft 13. The device includes a retainer 10 and angle adjusters 14 installed at both ends of a rotating shaft 13. Gear-shaped grooves 24 are formed inside the angle adjusters 14, and the outer contour of a gear 16 corresponds to and fits into the gear-shaped grooves 24, allowing the gear 16 to be locked in the grooves and preventing rotation. The gear 16 is fixedly installed inside the angle adjuster 14 on its outer side. An adjustment handle 15 is inserted into one end of the rotating shaft 13. A first spring 21 is installed on the side of the gear 16 away from the adjustment handle 15. There are two sets of first support columns 5, U-shaped groove blocks 2, angle adjusters 14, and bolts 3. These two sets are symmetrically distributed on the outer bottom surface of the back plate 1, facilitating better support when the back plate 1 is flat and allowing for adjustment of the back plate 1's angle according to individual needs.

[0025] Example 2

[0026] Please see Figure 1-3 A locking block 4 is fixedly installed on the back of the seat plate 9 and the back of the back plate 1. A square groove 17 is opened on the outer side of the first support column 5, and a first pressing block 7 is inserted into the square groove 17. A second spring 8 is fixedly installed between the first pressing block 7 and the second pressing block 18. A first pressing rod 6 and a second pressing rod 19 are installed on the side of the first pressing block 7 and the second pressing block 18 away from the second spring 8. This facilitates the compression of the first pressing block 7 and the second pressing block 18. A locking block 4 is fixedly installed on the outer surface of the back plate 1. A straight groove 20 is opened inside the locking block 4, which can be aligned with the square groove 17 after rotation. This allows the first pressing block 7 and the second pressing block 18 to be fixed in the square groove of the locking block 4.

[0027] Working principle: When adjusting the angle of the backrest 1 of the school seat, first press the adjustment handle 15 inward, causing the gear 16 connected to the adjustment handle 15 to move inward and disengage from the gear-shaped groove 24 inside the angle adjuster 14. Then rotate the adjustment handle 15, causing the gear 16 to drive the rotating shaft 13 to rotate, thereby causing the backrest 1 connected to the rotating shaft 13 to rotate. Adjust the backrest 1 to the required angle, release the adjustment handle 15, and the built-in first spring 21 will spring the gear 16 back into the gear-shaped groove 24, thereby fixing the gear 16, and then fixing the rotating shaft 13 and the backrest 1. When it is necessary to lay the backrest 1 flat as the seat 9, adjust the backrest 1 to be horizontal with the seat 9, then adjust the first support column 5 to be perpendicular to the backrest 1, and then press... The first pressure rod 6 and the second pressure rod 19 bring the first pressure block 7 and the second pressure block 18 close together. Then, the first pressure block 7 and the second pressure block 18 are inserted into the straight slot 20 in the locking block 4. The first pressure rod 6 and the second pressure rod 19 are released, and the second spring 8 built between the first pressure block 7 and the second pressure block 18 separates the first pressure block 7 and the second pressure block 18, thereby fixing the first support column 5. This allows the first support column 5 to support the back panel 1 and flatten the back panel 1, so that the back panel 1 can be used as a seat 9. Through the above operation, students can adjust the angle of the chair back according to their personal comfort and adjust the chair back to a horizontal state so that it can be used as an additional seat or for reclining and resting, thus fully responding to students' urgent needs for the multi-functionality and adaptability of the chair.
