The embodiments of the present application can reduce the cost of the balance mechanism and thereby reduce the cost of the mounting bracket.

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.

Provided is an articulated structure for connecting at least one arm rod, including a first connecting piece, a second connecting piece, a friction member and a pressing assembly. The friction member is inserted into one end of the arm rod, one end of the arm rod is articulated between the first connecting piece and the second connecting piece through a driving member, the driving member includes a stud, and the stud of the driving member sequentially penetrates through the first connecting piece, the friction member and one end of the arm rod and then threading mount with the second connecting piece. The pressing assembly is positioned between the first connecting piece and the second connecting piece and driven by the driving member to press against the friction member.

A support system for a display device includes a first arm configured to extend from a support surface. A second arm is rotatably connected to the first arm. The second arm has a range of movement relative to the first arm. A tilt head is rotatably connected to the second arm and configured to connect to a display. A first biasing member is positioned in the second arm and configured to provide a first counterbalancing force to the second arm to offset a load of the display. A second biasing member is positioned in the second arm and configured to provide a second counterbalancing force to the second arm to offset the load of the display. A lockout mechanism is configured to disengage the second biasing member and eliminate the second counterbalancing through at least a portion of the range of motion.

An adjustable support arm capable of providing users with a wide range of height, depth, tilt, and swivel options. The adjustable support arm may comprise an arm assembly releasably mounted to a base assembly. In further embodiments, the adjustable support arm may also comprise an articulating joint connected to the arm assembly, and an accessory bracket assembly connected to the articulating joint. A quick-release joint comprising a spring-loaded pivot latch may be utilized to releasably connect the arm assembly to the base assembly. To dampen side-to-side movement of the arm assembly, the adjustable support arm may also comprise a friction cartridge assembly comprising a taper-lock bushing and one or more set screws. A ring-shaped, adjustable panning insert can be coupled to the arm assembly to restrict the range of side-to-side motion of the support arm. The adjustable arm can further comprise a quick-release accessory fastening mechanism for easy removal and attachment of a mounted object (e.g., an electronic display, keyboard, or other item) to the support arm.

A display support having a freely adjustable height, including a base and a connector for installing a display, wherein an upper connecting arm and a lower connecting arm, which are parallel to each other, are arranged between the base and the connector. The display support further includes a mechanical spring, wherein an end of the mechanical spring is hinged with the connector or the lower connecting arm, the other end of the mechanical spring is hinged with a threaded sliding block, the threaded sliding block sleeves on a threaded rod, the threaded rod is arranged in the base, so that when an end part of the threaded rod is operated to drive the threaded rod to rotate, the threaded sliding block moves along the threaded rod, and a position of the threaded sliding block on the threaded rod is adjusted according to the weight of the display on the connector, so that when the connector is moved upwards or downwards, the connector is stopped at different heights relative to the base. The display support having the freely adjustable height can realize free stop of height adjustment, and thus is better than an air spring support.

A mounting system capable of mounting objects to support structures. The mounting system includes a wall mount including a display bracket configured to hold the object, a fixed support bracket coupleable to a vertical support structure, and a linkage assembly. The linkage assembly has a low-profile stowed configuration in which the object is held in a raised position close to the support structure. Tilt adjustment mechanisms are used to adjust the tilt of the display bracket.

Proposed is a vibration-proof hanger. According to one embodiment, the vibration-proof hanger includes a fitting bracket having a fixed plate configured to allow a first surface to be integrally fixed to an artificial structure, wherein a hinge unit is provided on a second surface of the fixed plate, a tilting arm unit configured to allow one end to be rotatably fixed to the hinge unit to be tilted, and a vibration-proof unit configured to be coupled to the tilting arm unit to absorb vibration transferred to the tilting arm unit or rotate to prevent vibration of the tilting arm unit.

An adjustable support arm capable of providing users with a wide range of height, depth, tilt, and swivel options. The adjustable support arm may comprise an arm assembly releasably mounted to a base assembly. In further embodiments, the adjustable support arm may also comprise an articulating joint connected to the arm assembly, and an accessory bracket assembly connected to the articulating joint. A quick-release joint comprising a spring-loaded pivot latch may be utilized to releasably connect the arm assembly to the base assembly. To dampen side-to-side movement of the arm assembly, the adjustable support arm may also comprise a friction cartridge assembly comprising a taper-lock bushing and one or more set screws. A ring-shaped, adjustable panning insert can be coupled to the arm assembly to restrict the range of side-to-side motion of the support arm. The adjustable arm can further comprise a quick-release accessory fastening mechanism for easy removal and attachment of a mounted object (e.g., an electronic display, keyboard, or other item) to the support arm.

A display device according to an embodiment includes: a display panel; a side frame that is disposed on a rear side of the display panel and disposed on opposite edges in a first direction of the display panel; a length change member that is disposed on the rear side of the display panel and has a changing length in the first direction; a link bar that is connected to one edge of the length change member; and a guide member where a connection portion of the length change member and the link bar is disposed, wherein the other edge of the link bar is connected to the side frame, and the guide member includes a curved groove, and the connection portion of the length change member and the link bar moves in the groove.
