The invention relates to a rotary connection device, a computer and electronic equipment including the rotary connection device, and the connection device is used for rotary connection of components of the computer and electronic equipment. The technical solution is: a rotary connection device, including at least one spindle, at least one bushing covering the outer surface of the spindle, at least one bushing is provided with a connecting piece for connection, and the bushing can be connected relative to the spindle. Rotation, characterized in that: the sleeve has an interference fit with the mandrel, so that the sleeve can rotate relative to the mandrel and stay at any position. According to the rotary connection device of the present invention, computers and electronic equipment realize reliable connection between the computer host and the display, and the display can stay in any position relative to the host, as well as the overall small size design.
Description
technical field [0001] The invention relates to a rotary connection device, a computer and electronic equipment including the rotary connection device, and the connection device is used for the rotary connection of parts of the computer and the electronic equipment. Background technique [0002] Existing structures that connect components of electronic equipment, such as the connection structure that connects the display of an all-in-one computer to the host computer, usually include a rotating shaft, and use a compression spring or a disc spring to keep the rotating shaft at a specific position by means of its torsion. In this way, the display can be kept at the desired angle, but in this case, the compression spring or disc spring is required to reach a torque of 10kg.cm, the diameter of the shaft needs to be above 8mm, and the integrated computer needs a small Volume, for some products, the maximum shaft size that can be accepted is 6mm. Therefore, the existing design of...
