A floating mechanism (300) and an ultrasonic diagnostic apparatus. The floating mechanism (300) and the ultrasonic diagnostic apparatus can implement the direct superposition of lifting movements and rotational movements, so that the floating mechanism (300) can move in more directions. In addition, a lifting structure and a rotation structure in the floating mechanism (300) are integrally linked in design, accordingly, the link performance is good, the response is fast, the occupied space is small, and the operation range is great.

A supporting device for bearing a display is provided. The supporting device comprises a base, a hollow housing, a bearing module, a linkage module, and an elastic element, wherein an elastic force provided by the elastic element is the greatest when the hollow housing is in a horizontal position; the elastic force decreases when the hollow housing moves from the horizontal position to a raised position, hence, the hollow housing can stop at any positons between the horizontal position and the raised position.

A display device and a driving method of the display device are provided. The display device includes a case, a first reel, a flexible display screen, and a retractable component. The first reel is located inside the case. The flexible display screen is wound on the first reel, and is retractable or expandable along a first direction. The retractable component includes a first retractable component including N retractable parts that are capable of sliding with respect to each other along the first direction, where N is a positive integer greater than or equal to 2. When the flexible display screen is expanded, the N retractable parts are expanded along the first direction and are arranged along a second direction, where the second direction intersects the first direction. When the flexible display screen is retracted, the N retractable parts are arranged in sequence along the second direction.

A mobile device holder that includes a body having a plurality of cavities. The mobile device holder includes a first assembly, a second assembly, and a third assembly. The first assembly is coupled to the body. The first assembly is configurable to be coupled to different portions of the body. The first assembly includes a first arm configured to be coupled to the body, a first slider coupled to the first arm, where the first slider is configured to move along the first arm, a first cap coupled to the first arm, and a first screw coupled to the first cap, where the first screw is configured to move the first slider along the first arm and towards the body.

Display assemblies for supporting displays on stands or support arms have mount portions to removably attach to the displays using magnetic assemblies and latches. The magnetic assemblies and latches can improve user experience and allow the display to be installed on a support arm from the viewing side of the display and without having to see or reach behind the display. Magnetic structures can center a mount portion of the support arm and a recess of the display and can attract them to each other. Laterally-extending latches can ensure the display is not inadvertently removed. Locking mechanisms can prevent the display from being rotated to a portrait orientation when sufficient space around the display and the necessary user intent is not provided.

The present disclosure relates to a movable rack arm assembly including a cam housing, a circular gear, a rack arm, a cam, and a spring assembly for contoured non-linear force transfer.

A phone gravity holder comprises a base, a pull rod configured to hold the phone, and a left clamping arm and a right clamping arm configured to clamp the phone, wherein the base is provided with a positioning shaft, the left clamping arm and the right clamping arm are both mounted on the positioning shaft in a rotatable manner, and the pull rod is respectively in transmission connection with the left clamping arm and the right clamping arm, respectively. When the phone is used, the phone is directly placed on the pull rod, and under the gravity effect of the phone, the pull rod drives the left clamping arm and the right clamping arm to rotate in reverse to clamp the phone. The phone can be clamped automatically by utilizing the gravity of the phone and simple mechanical principles, the structure is simple, and the production cost is greatly reduced.

Disclosed herein is an articulated support device. The articulated support device is formed to include a plurality of links connected to each other. A device stand is detachably coupled to the front end of the articulated support device and the rear end of the articulated support device is fixedly coupled to a structure detachably. The connection portions of the plurality of links are fixed not to move relative to each other or the connection portions are released to be rotatable relative to each other through an operation of a handle part provided on a front side of the articulated support device. The articulated support device includes a plurality of rotation and fixing units. Each of the plurality of rotation and fixing units includes a front link connection adapter, a wire central binding portion, a rotation regulation portion, a casing pipe, and an inner connection pipe.

The present disclosure provides a display mounting device, including a wall panel, an expansion hinge connection rod assembly, an adapter bracket, and a display bracket. The wall panel includes a main frame, two upper extension rods, and two lower extension rods. The main frame includes an upper beam, a lower beam, and a bearing plate. The two upper extension rods are respectively rotatably coupled to two ends of the upper beam to allow the two upper extension rods to be unfolded or folded relative to the upper beam. The lower extension rods are respectively rotatably coupled to two ends of the lower beam to allow the two lower extension rods to be unfolded or folded relative to the lower beam. Upper extension rods and lower extension rods can be folded and unfolded relative to the upper beam and the lower beam, thus meeting requirements of packaging size and installation size.
