Description

Connecting device

The present invention relates to a connection device, 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 areas range 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 the display screen is damaged due to several display units, the damaged display unit module needs to be removed from the grid to repair or replace the display panel. The removal of a large display unit module 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 module is repeatedly disassembled, the attached building structure or decorative panel may be damaged. The disassembly and maintenance work is complicated, labor-intensive, and time-consuming.

In addition, the display screen is usually set 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 inconvenience in repairing 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. Only in this way can you provide space for repairing or replacing the display unit. However, because the transparent surface of the display panel is farther away from the building glass, it affects the visual display effect of the luminous surface.

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

The connecting device comprises: a first fixing unit, comprising at least one first locking hole; a first locking piece passing through the first locking hole and fixed to the frame; a second fixing unit, wherein the second fixing unit is connected to the first fixing unit in an L-shape; a third fixing unit, comprising at least one third locking hole; and a fourth fixing unit, The fourth fixing unit is connected to the third fixing unit in an L-shape; wherein the display unit is fixed by the second fixing unit and the fourth fixing unit, and is fixed to the frame by the first fixing unit, and the third fixing unit is fixed to the frame; wherein the frame further comprises at least two first sub-frames, the first sub-frames are arranged in parallel, and both ends of each first sub-frame are connected to the frame; wherein the second fixing unit comprises at least one second locking hole, and the fourth fixing unit comprises at least one fourth locking hole. The connection device of item 1 of the patent application further includes a first locking base, a second locking base, a second locking fixture and a fourth locking fixture. The first locking base is disposed on the back of the display unit, the second locking base is disposed on the back 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 item 2 of the patent application, 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. For example, the connection device of item 1 of the patent application scope, wherein the first fixing unit and the third fixing unit have a short side and a long side, the long side of the first fixing unit is connected to the second fixing unit in an L-shape, the long side of the third fixing unit is connected to the fourth fixing unit in an L-shape, the length of the short side of the first fixing unit is equal to the length of the short side of the third fixing unit, and the length of the short side of the first fixing unit is greater than a first depth of the first sub-frame. A connecting device is provided for fixing a back side of a display unit on a frame, wherein the front side of the display unit includes a light-transmitting surface, and the display unit displays through the light-transmitting surface. The connecting device includes: a first fixing unit including at least one first locking hole; a first locking piece passing through the first locking hole and fixed to the frame; a second fixing unit, the second fixing unit and the first fixing unit are connected in an L-shape; a third fixing unit including at least one third locking hole; and a fourth fixing unit, the fourth fixing unit and the third fixing unit are connected in an L-shape; wherein the display unit is connected by the second fixing unit and the fourth fixing unit. The first fixing unit is fixed to the frame, and the third fixing unit is fixed to the frame; wherein the frame further comprises at least two second sub-frames, the second sub-frames are arranged in parallel, and the two ends of each second sub-frame are connected to the frame; wherein 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 released, the first fixing unit slides forward and backward, and the first locking piece slides in the first locking hole. When the first locking piece is locked, 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 5 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 a strip shape. 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. For example, the connection device of item 6 of the patent application scope, wherein 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 by one side of the display unit. A connecting 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 connecting 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 fixing unit in an L-shape, and the long side of the first fixing unit is connected to the seventh fixing unit in an L-shape; wherein 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; wherein the first locking seat and the third locking seat are tubular, the first locking seat and the third locking seat have a locking seat length in the axial direction, the second locking piece is accommodated in the first locking seat, and a sixth locking piece is accommodated in the third locking seat.
