Description

Technical Field

[0001] This utility model belongs to the field of office chair technology, specifically relating to a magnetic multifunctional office chair. Background Technology

[0002] In modern office environments, prolonged desk work has led to a growing demand for more comfortable, functional, and customizable office chairs. Traditional office chair backrests typically use fixed installations or simple angle adjustments, making it difficult to meet the precise needs of users of different heights and sitting postures. Some adjustable backrests rely on complex clip and bolt structures, which are not only cumbersome to adjust but also prone to loosening and squeaking after frequent use, affecting the user experience. Furthermore, traditional office chairs have relatively limited functionality and cannot quickly adapt to the diverse needs of work, rest, and meetings. Utility Model Content

[0003] In view of the above-mentioned shortcomings in the existing technology, the present invention provides a magnetic multifunctional office chair to solve the problems mentioned in the background technology.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A magnetic multi-functional office chair includes a seat and a backrest. The seat has armrests and a backrest, with a support rod connected to the lower end. The backrest includes a ring-shaped frame with two vertical rods in the middle. The bottom of the vertical rods is fixedly connected to the seat, and a vertically extending gap is formed between the two vertical rods. A cushion is magnetically connected to the gap, and a protrusion is fixedly connected to the side of the cushion facing the gap. The protrusion is embedded in the gap and forms a sliding guide engagement with the gap.

[0006] Preferably, the vertical rod is arc-shaped, and its curvature matches the main outline of the backrest. The top of the vertical rod is integrally formed with the frame or fixedly connected by bolts.

[0007] Preferably, a first magnet is fixedly embedded in the inner wall of the vertical rod near the gap, and the first magnet extends along the vertical direction of the vertical rod.

[0008] Preferably, a second magnet is fixedly embedded on the outer side wall of the protrusion. The first magnet and the second magnet are opposite pole magnets, and the two achieve a fixed connection between the pillow and the vertical rod through magnetic attraction.

[0009] Preferably, the end of the support rod furthest from the seat is connected to a caster wheel via a connecting rod, and the height of the support rod can be adjusted by an adjustment component.

[0010] Compared with the prior art, this utility model has the following advantages:

[0011] 1. The backrest is connected to the backrest by magnetic attraction. The strong magnetic attraction between opposite magnets can make the backrest firmly fixed in the selected position. The adjustment process does not require any tools. Users only need to manually push the backrest to quickly and accurately adjust its vertical position, which can meet the personalized needs of users with different heights and sitting postures. The operation is simple and efficient.

[0012] 2. Combining multiple functions such as magnetic headrest adjustment, seat height adjustment, and flexible movement with casters, the office chair can adapt to various scenarios such as working, resting, and meetings;

[0013] 3. Compared with the traditional headrest adjustment structure, the magnetic design of this invention reduces complex mechanical parts, lowers the probability of part wear and failure, and improves the overall stability and durability of the office chair structure.

[0023] Example 1:

[0024] like Figure 1-3 As shown, this utility model relates to a magnetically attached multifunctional office chair, comprising a seat 1 and a backrest 2. The seat 1 has armrests 5 and a backrest 2, with a support rod 3 connected to its lower end. The armrests 5 are installed at preset mounting positions on both sides of the seat 1 and fixed using bolts, nuts, and other connectors. The backrest 2 includes a ring-shaped frame 23. Two vertical rods 21 are provided in the middle of the frame 23. The bottom of the vertical rods 21 is fixedly connected to the seat 1, and a vertically extending gap 22 is formed between the two vertical rods 21. A cushion 6 is magnetically attached to the gap 22. A protrusion 61 is fixedly connected to the side of the cushion 6 facing the gap 22, and the protrusion 61 is embedded in the gap 22 and forms a sliding guide engagement with the gap 22. The main body of the cushion 6 is filled with cotton, and a protrusion 61 is provided at its rear end. When in use, the protruding part is located in the gap 22, and the other end is placed behind the backrest 2. Figure 1 As shown.

[0025] In this embodiment, the vertical rod 21 is arc-shaped, and its curvature matches the main outline of the backrest 2. The top of the vertical rod 21 is integrally formed with the frame 23 or fixedly connected by bolts.

[0026] In this embodiment, a first magnet 24 is fixedly embedded on the inner sidewall of the vertical rod 21 near the gap 22, and the first magnet 24 extends along the vertical direction of the vertical rod 21.

[0027] In this embodiment, a second magnet 62 is fixedly embedded on the outer side wall of the protrusion 61. The first magnet 24 and the second magnet 62 are opposite pole magnets. The two achieve a fixed connection between the pillow 6 and the vertical rod 21 through magnetic attraction. The surface of the magnet is provided with an anti-rust coating.

[0028] In this embodiment, the end of the support rod 3 furthest from the seat 1 is connected to a caster wheel 4 via a connecting rod, and the height of the support rod 3 can be adjusted by the adjustment assembly 31. The caster wheel 4 can be fastened with bolts or other suitable connection methods, and both the connection method and the adjustment assembly 31 are existing technologies.

[0029] In practical use

[0030] Height adjustment: The height of seat 1 can be adjusted via adjustment component 31;

[0031] Positioning: By pushing the office chair, the casters 4 can rotate freely on the ground, making it easy to move the office chair to the desired position;

[0032] Pillow Adjustment: Users can hold the pillow 6 with their hands, apply appropriate force to overcome the magnetic attraction between the first magnet 24 and the second magnet 62, and slide the pillow up or down to a suitable position according to their height, sitting posture, and comfort needs. During the sliding process, users can make fine adjustments according to their own feelings to find the most comfortable support position. After releasing their hands, the pillow 6 is stably fixed in the new position under the action of magnetic attraction, providing comfortable neck or waist support for the user.

[0033] The above are merely embodiments of this utility model.
