Abstract: A device for mounting an electronic display to a wall includes: a fixing plate defining an inner gear wheel; a display-mounting bracket configured to vertically tilt relative to the fixing plate, the display-mounting bracket having a proximal extension with an eccentric gear having a locking shaft, the eccentric gear being configured to engage with the inner gear wheel; a spring coupled between the main fixing plate and the locking shaft such that the spring retains a vertical-tilt orientation of the display-mounting bracket relative to the main fixing plate; and an adjustment screw coupled to the lower end of the tension spring, wherein rotation of the adjustment screw expands or compresses the spring.

Abstract: A device for mounting an electronic display to a wall includes: a fixing plate; a display-mounting bracket configured to vertically tilt relative to the fixing plate, wherein the display-mounting bracket includes a proximal extension defining a damper housing; an adjustment screw extending through the damper housing; a damper slider disposed around the screw; and a spring coupled between the fixing plate and the slider such that: the spring provides a counterbalancing force against a weight of the display to retain a vertical-tilt orientation of the display, and rotation of the screw causes a proximal or distal translation of the slider relative to the fixing plate and adjusts an orientation of the spring relative to a vertical axis of the fixing plate, thereby modifying the counterbalancing force.

Abstract: An angle adjustment apparatus includes a first connector, a second connector, a first adjusting member, a second adjusting member, and a third adjusting member. The third end of the second connector is rotatably connected to the first end of the first connector through a pivot shaft. The first adjusting member is connected to the second end of the first connector. The second adjusting member is connected to the fourth end of the second connector. The third adjusting member is configured to adjust a distance between the second end of the first connector and the fourth end of the second connector. At least one of the first adjusting member and the second adjusting member is rotatably connected to the first connector corresponding thereto or the second connector corresponding thereto, and a rotation axis for the rotatable connection is parallel to the pivot shaft.
