Description

Technical Field

[0001] The utility model belongs to the technical field of LED screens, and more specifically, it particularly relates to an external wiring device for LED screens. Background Art

[0002] An LED screen is a new type of imaging electronic device made by arranging light-emitting diodes in sequence. Due to its characteristics such as high brightness, wide viewing angle, and long service life, it is widely used in products such as outdoor advertising screens.

[0003] When some current external wiring devices for LED screens connect the wiring to the controller, in order to avoid the situation of insufficient wiring length, the length of the wiring is usually increased. However, this also causes the excess sections of multiple wirings to be stacked together in a messy manner after the connection is completed. When subsequent workers perform maintenance and replacement of the wiring, they need to first sort out the arrangement of the wiring before they can carry out the next maintenance and replacement work. This process is time-consuming and laborious, reducing work efficiency.

[0004] Therefore, in view of this, the existing structures and deficiencies are studied and improved to provide an external wiring device for LED screens, with the expectation of achieving a more practical value. Content of the Utility Model

[0005] In order to solve the above technical problems, the utility model provides an external wiring device for LED screens, which is achieved by the following specific technical means:

[0006] The external wiring device for LED screens includes a controller body and a mounting base. One side of the controller body is provided with a pair of connection slots. One side of the connection slot is installed with a locking bolt. One side of the mounting base is installed with a pair of connection blocks. One side of the upper end surface of the mounting base is installed with a mounting block. The upper end surface of the mounting block is provided with a plurality of placement slots. A wire winding mechanism is installed in the placement slots. The wire winding mechanism includes a pair of circular disks and a wire winding shaft. A wire winding shaft is installed between the pair of circular disks. The bottom end of the wire winding shaft is provided with a movable slot. A support rod is movably connected in the movable slot. The bottom end of the support rod penetrates the bottom surface of one of the circular disks and is connected to the bottom of the placement slot. A compression spring is installed between the bottom surface of one of the circular disks and the bottom of the placement slot around the outer periphery of the support rod. A clamping block is rotatably connected to one side of the upper end surface of the mounting block near the plurality of placement slots.

[0007] Further, a plurality of wiring holes are provided on one side of the controller body close to the pair of connection slots.

[0008] Further, a threaded groove is provided on one side of each of the pair of connection blocks. The thread in the threaded groove matches the thread on the surface of the locking bolt.

[0009] Furthermore, a limiting block is installed at the top end of the support rod within the movable slot.

[0010] Furthermore, a pair of through slots are provided on both sides of the placement slot, and the positions of the through slots correspond to the positions of the wiring holes.

[0011] Furthermore, a rotating block is installed on the upper end surface of the clamping block.

[0012] Furthermore, the connecting block and the connecting slot are of matching dimensions.

[0013] Compared with the prior art, the present utility model has the following beneficial effects:

[0014] Through the combined use of the wire winding shaft, support rod, limiting block, compression spring, rotating block and clamping block, when the staff connects the two ends of the wiring to the controller body and the LED screen respectively, the redundant section of the wiring is wound around the wire winding shaft, and the two ends of the wiring pass through a pair of through slots respectively, and then the wire winding mechanism is pushed into the placement slot. At this time, the rotating block is rotated, and the rotating block drives the clamping block to rotate to the upper end surface of the circular disc to fix the wire winding mechanism, so as to achieve the effect of quickly and conveniently arranging the wiring, avoiding the redundant sections of multiple wirings being wound together in a mess. When it is necessary to replace the wiring or increase the length of the wiring, the clamping block is rotated by the rotating block to move the clamping block away from the circular disc. At this time, under the action of the compression spring, the compression spring pushes the wire winding mechanism upward in the placement slot. At this time, the staff can take out the wiring, so as to facilitate the staff to increase the length of the wiring or replace the wiring, thereby improving the use effect of the product.
