Description

Connecting device

The present invention relates to a connection device, and in particular to a connection device in the field of display devices.

Traditional outdoor displays are mostly hung outside buildings, or closely attached between building glass and structures. Their area ranges from a few square meters to tens of meters or hundreds of square meters. The display is installed on a frame, which is set on the building structure. The frame is composed of multiple partitions, and the display is composed of several display units. The display is connected to a display unit with a grid.

When a display screen is damaged due to several display units, the damaged display unit modules need to be removed from the grid to repair or replace the display panel. The removal of large display unit modules is usually not something that can be done by one person alone, and usually requires 2 or 3 people or more. In addition, when the display unit modules are repeatedly removed, the attached building structure or decorative panels may be damaged. The removal and maintenance work is complicated, labor-intensive, and time-consuming.

In addition, the display screen is usually placed between the frame and the building glass. In order to achieve a good display effect, the distance between the front of the display unit and the building glass is usually very close, but this will cause space restrictions and make it inconvenient to repair the display unit. If you want to easily remove the display unit, the transparent surface of the display unit must be farther away from the building glass to provide space for repair or replacement of the display unit. However, because the transparent surface of the display panel is farther away from the building glass, the visual display effect of the luminous surface is affected.

Therefore, the current display connection device has the problem of being difficult to repair and needs to be improved.

The connecting device of item 3 of the patent application further includes a first locking base, a second locking base, a second locking fixture and a fourth locking fixture, wherein the first locking base is arranged on the back side of the display unit, the second locking base is arranged on the back side of the display unit, the second locking fixture is connected to the first locking base, and the fourth locking fixture is connected to the second locking base. For example, in the connection device of claim 4, the first locking seat and the second locking seat are tubular, the first locking seat and the second locking seat have a locking seat length in the axial direction, the second locking member is accommodated in the first locking seat, and a fourth locking member is accommodated in the second locking seat. As in the connection device of item 2 of the patent application scope, the first fixed unit and the third fixed unit have a short side and a long side, the long side of the first fixed unit is connected to the second fixed unit in an L-shape, the long side of the third fixed unit is connected to the fourth fixed unit in an L-shape, the length of the short side of the first fixed unit is equal to the length of the short side of the third fixed unit, and the length of the short side of the first fixed unit is greater than a first depth of the first sub-frame. For example, in the connection device of claim 1, the frame further comprises at least two second sub-frames, the second sub-frames are arranged in parallel, and two ends of each second sub-frame are connected to the frame. For example, in the connection device of item 7 of the patent application, the first locking hole is in the shape of a long strip, and the first locking piece passes through the first locking hole. When the first locking piece is loosened, the first fixing unit slides back and forth, and the first locking piece slides in the first locking hole. When the first locking piece is tightened, the first locking piece is fixed to the second sub-frame, and the display unit is clamped between the second fixing unit and the second sub-frame by sliding the first locking unit. For example, the connection device of item 8 of the patent application further includes a fifth fixing unit, a sixth fixing unit and a fifth locking piece. The sixth fixing unit is connected to the fifth fixing unit in an L-shape. The fifth fixing unit includes at least one fifth locking hole. The fifth locking piece passes through the fifth locking hole and is fixed to the frame. The fifth locking hole is in the shape of a long strip. The fifth locking piece passes through the fifth locking hole. When the fifth locking piece is released, the fifth fixing unit slides forward and backward, and the fifth locking piece slides in the fifth locking hole. When the fifth locking piece is locked, the fifth locking piece is fixed to the second sub-frame. By sliding the fifth locking unit, the display unit is clamped between the sixth fixing unit and the second sub-frame. As for the connection device of item 9 of the patent application scope, the second subframe includes two long sides and two short sides, the short side close to the sixth fixing unit includes a clamping unit, the width of the clamping unit is greater than the width of the short side, and the clamping unit is connected to a soft pad against one side of the display unit. A connection device is provided for fixing a back side of a display unit on a frame, the front side of the display unit includes a light-transmitting surface, and the display unit displays through the light-transmitting surface. The connection device includes: a first fixing unit; a second fixing unit, the second fixing unit is connected to the first fixing unit in an L-shape; a second locking piece passes through the second locking hole to fix the display unit; a fifth fixing unit; a sixth fixing unit, including at least one sixth locking hole, the fifth fixing unit is connected to the sixth fixing unit in an L-shape; a sixth locking piece passes through the sixth locking hole to fix the display unit; and, a seventh fixing unit, the long side of the fifth fixing unit is connected to the seventh connection unit in an L-shape, and the long side of the first fixing unit is connected to the seventh connection unit in an L-shape; The display unit is fixed by the second fixing unit and the sixth fixing unit, and is fixed to the frame by the short sides of the first fixing unit, the fifth fixing unit and the seventh fixing unit. For example, in the connection device of claim 11, the first locking seat and the third locking seat are tubular, and the first locking seat and the third locking seat have a locking seat length in the axial direction. The second locking member is accommodated in the first locking seat, and a sixth locking member is accommodated in the third locking seat.
