Description

LED display frame fixture {LED DISPLAY FRAME ANCHOR}

The present invention relates to an LED display frame fixture, and in particular, a locking guide having a locking pin is coupled to one side of the fixed frame, and a locking hook corresponding to the locking guide is coupled to the inside of the fixed frame so that the fixed frame is engaged with each other. The hook is caught by the locking pin to maintain the pulled state.

In general, a multi-vision system uses a display device such as a CRT or LCD as a unit and arranges the display devices in a plurality of rows and columns to form a large screen. A different screen is displayed on each unit display device or a single screen is displayed. Refers to a device that is divided and displayed on a unit display device.

Such multi-vision display devices include products such as a multi-cube with a transmissive screen and a projector installed in a box of a predetermined size, a multi-cube using an LCD monitor, a multi-cube using a DLP, etc. These multi-vision systems are becoming increasingly important as visual information transmission devices in various fields such as broadcast programs, large stages, big events, concerts, and brand presentations.

Such a multi-vision system may be used for fixed installation, such as indoor and outdoor electronic signboards, but is generally used for rental of repeating installation and dismantling on a large screen having a predetermined size and shape as needed in a performance hall or an event event.

However, the conventional multi-vision display device generally has a structure including a box-shaped frame having a predetermined width and length. Therefore, when a plurality of display devices are arranged in a row, a large installation space is required. In particular, since the weight and volume of each unit display device go out, there is a problem in that repeated installation and dismantling operations are not easy.

On the other hand, in recent years, display devices using brighter, lighter, and semi-permanent LEDs are being used as rental multi-visions as well as conventional outdoor display boards, compared to existing multi-vision displays using CRT, LCD, and DLP. to be.

However, the conventional LED display device is made of a structure in which the LED module consisting of a plurality of LEDs are coupled to a single LED panel fixing frame in a constant array, and the fixing frame is coupled horizontally and vertically and detachably coupled with screws. Since it is necessary to manufacture a separate fixed frame according to a change in screen size or a change in screen form required when renting, there is a problem that the restriction of the productivity and the size and shape of the installation screen are bound to follow.

According to the present invention, the fixing frame in which the LED module is arranged is aligned horizontally and vertically so that the locking hooks provided in the lead-out guides are pulled in a locked state by the locking pins of the locking guides. According to the shape change, it is possible to freely expand the size and shape of the installation screen.

In addition, by reducing the volume and weight of the fixed frame through this, it is possible to obtain an effect that can be easily installed and dismantled the LED display device.

The process of installing the LED display frame having such a fixture is as follows.

First, as shown in FIG. 6A, the lower horizontal member 101 constituting another fixed frame 10 is positioned in a parallel state on the upper part of the upper horizontal member 101 constituting the fixed frame 10. The catch guide 20 formed in the lower horizontal member 101 is matched with the draw-out guide 31 coupled to the upper horizontal member 101 in a state.

At this time, the catching hook piece 36 coupled to the pull-out guide 31 is struck or pulled downward by the weight of the catching hook piece 36 and the handle screw 35, that is, of the catching hook piece 36. The tip of the hook head 365 formed on the top is maintained in the inserted state of the second long hole 321 of the pull-out guide 31. Therefore, in the process of moving or storing the fixed frame 10 it can be prevented from being touched or caught outside.

On the other hand, the portion shown by the dashed line is an expression that when the latching hook 30 is installed on the other left and right vertical member 102 having the longitudinal direction, it can be maintained inclined to one side due to the load.

Next, as shown in FIG. 6B, the lower portion of the lower horizontal member 101 is brought into contact with the upper portion of the upper horizontal member 101, and the handle screw 35 is pushed upward while holding the finger with the hook. The head pulling hole 366 and the vertical guide hole 363 formed in the piece 36 are guided by the guide pins 33, and the second head hole 321 in which the hook head 365 is formed in the draw-out guide 31 is formed. Will be withdrawn to the top of.

Next, the locking pin hook groove 367 formed in the hook head 365 of the hook hook piece 36 drawn out is caught by the locking pin 21 provided in the locking guide 20, and then the handle screw 35 is removed. At the same time as the rotation, the male screw 342 coupled to the female screw 352 is moved to the lower portion of the hollow handle 351. That is, while the male screw 34 is pulled, the portion where the female screw 352 of the handle screw 35 starts is rotated in a state where the lower portion of the upper horizontal member 101 abuts the inner side of the left vertical member 102. As a result, the state in which the hook hook piece 36 is strongly pulled is maintained.

Meanwhile, the dismantling process of the LED display frame is performed through the reverse process described above.
