Embodiment Construction

[0026] The present invention will be further described in detail through the accompanying drawings and specific embodiments below.

[0027] Such as Figure 1-4 As shown, this embodiment provides a rotating device, which includes a rotating part 1 and a fixed part 2 that can rotate relatively and are arranged coaxially. The fixed part 2 includes a lower half 21 and an upper half 22. The lower half 21 is a plate shape provided with a recessed chamber, the upper half 22 is ring-shaped covering the lower half 21, and the rotating part is installed in the recessed chamber.

[0028] Several rollers 3 are arranged between the rotating part 1 and the fixed part 2, and the rollers 3 support the rotating part 1 and when the rotating part 1 and the fixed part 2 rotate relatively, the The roller 3 can rotate by itself under the action of the rotating part 1 (rolling friction). Such as figure 2 As shown, the roller 3 includes a roller shaft 31 and a wheel disc 32, the roller 3 is locat...

Abstract

The invention discloses a rotating device. The rotating device comprises a rotating portion and a fixed portion which are coaxially arranged, wherein the rotating portion can rotate relative to the fixed portion. A plurality of rollers are arranged between the rotating portion and the fixed portion and support the rotating portion. When the rotating portion rotates relative to the fixed portion, the rollers can rotate around the axes of the rollers under the action of the rotating portion. A locking portion is arranged on the fixed portion and installed on the fixed portion through a rotating shaft. The locking portion comprises a circular plate portion provided with a gap. The circular plate portion is located on the radial outer side of the rotating portion. A plurality of arc receding grooves are formed in the outer circumferential wall of the rotating portion. By the adoption of the rotating device, uniform friction force can be provided in the circumferential direction of the rotating portion through rotation of the rollers, it is guaranteed that the rotating portion rotates stably, the rotating portion can be locked tightly through the locking portion when rotating to an appointed position, and besides the locking portion is simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to a rotating device and belongs to the technical field of medical instruments. Background technique [0002] Rotating devices are often used in the technical field of medical instruments, that is, the rotating parts are installed on the fixed parts, and the rotating parts are turned to adjust to a proper position during use to facilitate medical operations. The rotary devices in the prior art are unstable in the rotation process and easy to wear, and some have no locking device, and although some have a locking device, the structure of the locking device is relatively complicated and difficult to operate. Contents of the invention [0003] Therefore, the purpose of the present invention is to overcome the defects in the prior art, to provide a locking and positioning in the process of reciprocating rotation, and stable structure, relatively stable relative rotation between parts, not easy to cause wear, long service life rotat...
