Rotating device with damping structure and swivel chair

Abstract

A rotating device and swivel chair with a damping structure are disclosed. The rotating device includes a rotating shaft component and a bushing component, with the bushing component disposed around the rotating shaft component. A damping element is sleeved on the rotating shaft component and located between the rotating shaft component and the bushing component, engaging with the bushing component. When the rotating shaft component drives the damping element to rotate relative to the bushing component, the damping element and the bushing component rub against each other. This invention, by incorporating a damping element located between the rotating shaft component and the bushing component, and engaging with the bushing component, increases friction during the rotation of the rotating shaft component. This prevents the rotating shaft component from rotating too quickly, thus preventing the chair cushion from rotating too quickly and affecting the user experience. Furthermore, it provides a damped feel during the rotation of the rotating shaft component, thereby improving the tactile feedback of the rotating device.

Technical Field

[0001] This utility model relates to the field of swivel chair technology, and in particular to a rotating device with a damping structure and a swivel chair. Background Technology

[0002] The swivel chair's rotating mechanism includes a pivot component and a bushing component. The bushing component is located around the pivot component, the pivot component is located on the seat cushion, and the bushing component is located on the chair base. The pivot component rotates relative to the bushing component, thereby causing the seat cushion to rotate and be positioned on the chair base. However, the pivot component is prone to rotating too fast relative to the bushing component, causing the seat cushion to rotate too quickly and affecting the user experience.

[0003] Therefore, further improvements are necessary. Utility Model Content

[0007] A damping element is sleeved on the rotating shaft component and located between the rotating shaft component and the bushing component. The damping element is in contact with the bushing component. When the rotating shaft component drives the damping element to rotate relative to the bushing component, the damping element and the bushing component rub against each other.

[0008] The damping component has several damping teeth distributed around its circumference. The damping teeth contact and engage with the inner wall of the bushing component, so that when the rotating shaft component drives the damping component to rotate relative to the bushing component, the damping teeth and the inner wall of the bushing component rub against each other.

[0009] There is a gap between two adjacent damping teeth.

[0010] The outer side of the damping tooth is provided with a mating surface that contacts and engages with the inner sidewall of the bushing component.

[0011] The damping component is provided with a sleeve hole, and the rotating shaft component is provided with a sleeve part. The damping component is sleeved on the sleeve part through the sleeve hole.

[0012] The bushing assembly has an inner hole, the rotating shaft assembly passes through the inner hole, and the damping component is located inside the inner hole.

[0013] It also includes a bearing assembly, which includes a first bearing and a second bearing. The first bearing is sleeved on the rotating shaft component and located on the upper part of the bushing component, and the second bearing is sleeved on the rotating shaft component and located on the lower part of the bushing component. The first bearing and the second bearing are respectively located between the rotating shaft component and the bushing component.

[0014] The upper end of the damping element abuts against the first bearing, and / or the lower end of the damping element abuts against the second bearing.

[0015] The bushing component has a first positioning step and a second positioning step at its upper and lower ends, respectively. The rotating shaft component has a third positioning step and a retaining ring distributed vertically.

[0016] A swivel chair designed for this purpose includes a chair base and a chair cushion, characterized in that it further includes the aforementioned rotating device with a damping structure, wherein a rotating shaft component is disposed on one of the chair base and the chair cushion, and a bushing component is disposed on the other of the chair base and the chair cushion.

[0017] The rotating device of this utility model incorporates a damping element located between the rotating shaft component and the bushing component. The damping element contacts and engages with the bushing component. When the rotating shaft component drives the damping element to rotate relative to the bushing component, the damping element and the bushing component rub against each other. The damping element increases the friction when the rotating shaft component rotates, preventing the rotating shaft component from rotating too fast, thereby preventing the chair cushion from rotating too fast and affecting the user experience. Moreover, it provides a damping feel when the rotating shaft component rotates, thus improving the rotation feel of the rotating device. Attached Figure Description
