Problems solved by technology
The display cabinet originally needed to install a connecting piece and 4 screws between the 4 cabinets to level the flatness between the cabinets, so as to achieve the effect of no step difference between the cabinets. The installation process is long and the cost of using the connecting piece is high. High; in order to reduce the cost of the screen body and quickly install the screen body, it is urgent to design a fast adjustment installation mechanism for the flatness of the cabinet, which can be quickly removed after the display cabinet is installed, so as to achieve recycling during the installation process

Embodiment 2
Embodiment 3
[0028] Embodiment 3. The difference between this embodiment and Embodiment 1 is that the connecting rod grabbing hook mechanism 3 is evenly provided with three connecting rod grabbing hook assemblies 32. For three hexagonal casings, it is not suitable to adopt the four-corner link grapple mechanism of Embodiment 1, and the triangular link grapple mechanism of the present embodiment is suitable for use this moment.

The invention discloses an installation mechanism for quickly adjusting the flatness of an LED display box, which includes a connecting rod base, a lifting and ejecting mechanism, a connecting rod grabbing hook mechanism and an eccentric handle mechanism. The lifting and ejecting mechanism passes through the connecting rod. Rod base, the connecting rod grab mechanism and the eccentric handle mechanism are covered on the connecting rod base, the eccentric handle mechanism is arranged above the connecting rod grab mechanism; the lifting and ejecting mechanism is set There are threaded lifting and ejecting rods, protective backing plates, opening springs and lifting and ejecting handles, and the connecting rod grab mechanism is provided with connecting rod movable seats, connecting rod grabbing hook assemblies and movable seat springs; its beneficial effect is that the present invention An installation mechanism for quickly adjusting the flatness of the LED display box is equipped with an eccentric cam handle, which can quickly press and release the connecting rod grab mechanism by rotating the eccentric cam handle, thereby controlling the connecting rod grab component to quickly retract inward and outward When opened, there is also a protective backing plate, which can be rotated 360 degrees to protect the pressing surface of the box from damage.
Description
technical field [0001] The invention relates to the technical field of installation of LED fixed-mounted full-color display screens, in particular to an installation mechanism for quickly adjusting the flatness of an LED display screen box. Background technique [0002] At present, the application of small-pitch LED fixed-mounted display screens is becoming more and more extensive, and the display effect requirements for small-pitch display screens are also getting higher and higher. The step difference is installed on the box body to meet the requirements for high-definition display effect of the screen body. The display cabinet originally needed to install a connecting piece and 4 screws between the 4 cabinets to level the flatness between the cabinets, so as to achieve the effect of no step difference between the cabinets. This installation process takes a long time and costs a lot by using the connecting piece. High; in order to reduce the cost of the screen body and qu...
