Description

Technical Field

[0001] This utility model relates to the field of office chair technology, and in particular to detachable office chair armrests and support structures. Background Technology

[0002] Office chairs are furniture designed specifically for office settings and for users to sit on. The armrests of office chairs are mainly used to improve comfort and convenience. On the one hand, they provide stable support for the arms, allowing the shoulder and arm muscles to relax naturally and reducing fatigue caused by the upper limbs being suspended for a long time. This is beneficial for long-term office operations such as typing and using a mouse. On the other hand, the armrests define a comfortable sitting range, helping users find the right sitting posture and maintain the stability of the body on the chair. Together with the backrest and seat, they create a more ergonomic office seating experience.

[0003] The design of a typical office chair usually involves welding and assembling multiple steel pipes. The armrests are made of a single bent steel pipe. To protect the user's arms from direct contact with the metal edges, these armrests are usually equipped with a soft plastic protective shell.

[0004] In existing technologies, the connection between armrests and chair frames is often quite complex, difficult to disassemble, and prone to damaging the chair frame. This not only makes cleaning and maintenance inconvenient, but also fails to meet the personalized needs of different users for armrest angles, heights, and other aspects. Utility Model Content

[0005] The detachable office chair armrest and support structure proposed in this utility model aims to improve the problems in the existing technology where the connection between the armrest and the chair frame is relatively complicated, disassembly is difficult, and the individual needs of different users for armrest angle, height, etc. are not met.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a detachable office chair armrest and support structure, including a seat support base, a seat cushion fixedly connected to the top of the seat support base, a backrest fixedly connected to one end of the seat cushion, a base frame fixedly connected to the bottom of the seat support base, support bolts threadedly connected to the interior of the seat support base, support mechanisms provided on both sides of the seat support base, disassembly components provided inside the support mechanisms, armrest structures provided on the top of each support mechanism, support components provided inside the armrest structures, the support mechanisms including an adjusting connecting plate, one end of the adjusting connecting plate fixedly connected to both sides of the seat support base, and an armrest base slidably connected to the end of the adjusting connecting plate away from the seat support base, with adjusting grooves provided inside the armrest base on both sides near the adjusting connecting plate, connecting bolts slidably connected inside the adjusting grooves, and fixing nuts threadedly connected to both ends of the connecting bolts.

[0007] As a further description of the above technical solution: the disassembly component includes an armrest slot, which is located at the top of the armrest base away from the adjusting connecting plate. An armrest buckle is slidably connected inside the armrest slot, and a fixing groove is provided inside the armrest buckle.

[0008] As a further description of the above technical solution: a fixing buckle is rotatably connected inside the fixing groove, a knob is fixedly connected inside the fixing buckle, and the knob is rotatably connected to the end of the armrest base away from the adjusting connecting plate.

[0009] As a further description of the above technical solution: a sliding shell is fixedly connected to the top of the armrest buckle, and a disassembly seat is fixedly connected to the top of the sliding shell on the side near the adjusting connecting plate. A limit plate is fixedly connected to the inner side of the sliding shell on the side near the disassembly seat.

[0010] As a further description of the above technical solution: a button is slidably connected to the end of the disassembly seat away from the limiting plate, a spring is fixedly connected to the bottom inner side of the disassembly seat, a baffle is fixedly connected to the end of the spring away from the disassembly seat, and a disassembly fixing block is slidably connected to the end of the baffle close to the limiting plate.

[0011] As a further description of the above technical solution: the handrail structure includes a handrail frame, the outside of which is slidably connected to the inside of the sliding shell, a limiting groove is provided on the side of the handrail frame near the limiting plate, and a support plate is fixedly connected to the top of the handrail frame.

[0012] As a further description of the above technical solution: the top of the support plate is rotatably connected to a rotating shaft, the outer side of the rotating shaft is slidably connected to an adjusting plate, the top of the adjusting plate is provided with a movable groove, and the inside of the movable groove is slidably connected to a movable slider.

[0013] As a further description of the above technical solution: the internal rotating connection of the movable slider is to the top outside of the rotating shaft, and the internal fixed connection of the adjusting plate is to three fixing bolts, and the top of the fixing bolts is fixedly connected to a handle.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by adjusting the connecting bolts and fixing nuts on the connecting plate, the distance between the armrest and the office chair can be adjusted by sliding them in the adjustment groove on the armrest base. Loosening the fixing nuts and pulling out the connecting bolts allows the armrest base to be detached. By rotating the knob on the armrest base, the armrest clips can be removed from the armrest clip groove in the armrest base. By pressing the button in the disassembly seat, the baffle compresses the spring, allowing the armrest frame to be removed from the sliding shell. This simplifies the connection method between the armrest and the chair frame and makes disassembly convenient.

[0016] 2. In this utility model, the rotating shaft and movable slider in the support plate on the handrail frame allow the adjustment plate to rotate. The adjustment plate slides on the outside of the movable slider through the movable groove in the adjustment plate, thereby adjusting the position of the handrail handle. The adjustment plate and the handrail handle are fixed by fixing bolts, making the user more comfortable and solving the problem of not being able to meet the personalized needs of different users for handrail angle, height and other personalized requirements.
