A locking bolt 9 is threaded inside each of the two screw sleeves 12.

[0037] The support frame 2 is externally slidably connected to the interior of the two uprights 11. The interior of the two uprights 11 is provided with movable grooves that are adapted to the support frame 2, which can provide guidance for the movement of the support frame 2. One side of the locking bolt 9 overlaps with one side of the support frame 2, and the support frame 2 is locked by the locking bolt 9. The technology is mature and will not be described in detail here. A positioning groove is opened on the top of the support frame 2. A fixing frame 21 is fixedly installed on one side of the support frame 2. A through hole is opened on one side of the fixing frame 21. Several rotating blocks 22 are fixedly installed on the top of the support frame 2 to support the rotating shaft 33.

[0038] The external of the locking block 7 is slidably connected to the inside of the positioning groove. A connecting rod 71 is fixedly connected to one side of the locking block 7. The external of the connecting rod 71 is slidably connected to the inside of the through hole. A spring 72 is sleeved on the outside of the connecting rod 71. The spring 72 can push the locking block 7 to press against the ratchet 34 to prevent the light box 3 from rotating downward. The two sides of the spring 72 are respectively attached to one side of the locking block 7 and the fixing bracket 21. A pull block 73 is fixedly installed on one side of the connecting rod 71. When it is necessary to rotate the light box 3 downward, the locking block 7 is disengaged from the ratchet 34 by pulling the pull block 73. The ratchet 34 is unrestrained and can rotate downward.

[0039] Two fixing blocks 32 are fixedly installed on one side of the light box 3. A rotating shaft 33 is fixedly installed inside the two fixing blocks 32. The outside of the rotating shaft 33 is adapted to the inside of the rotating block 22. The outside of the rotating shaft 33 is rotatably connected to the inside of the rotating block 22.

[0040] A ratchet 34 is fixedly installed on the outside of the rotating shaft 33. The ratchet 34 is located above the locking block 7. One side of the ratchet 34 is engaged with one side of the locking block 7. The locking block 7 locks the ratchet 34 to prevent the light box 3 from rotating downward. This part has a simple structure and technicians can implement and operate it according to the plan.

[0041] A slot 35 is provided on one side of the light box 3, and a sliding groove 36 is provided on one side of the slot 35. The interior of the sliding groove 36 is adapted to the exterior of the mounting bracket 4, and the interior of the sliding groove 36 is slidably connected to the exterior of the mounting bracket 4. A through groove 37 is provided on one side of the light box 3 to facilitate pushing the push plate 41.

[0042] A push plate 41 is fixedly installed on one side of the mounting bracket 4. The outside of the push plate 41 is snapped into the inside of the slot 35. A placement slot 42 is opened on one side of the mounting bracket 4. The outside of the advertising display board 5 is adapted to the inside of the placement slot 42. When replacing the advertising display board 5, the worker puts his hand into the through slot 37 and pushes the push plate 41. Then the push plate 41 can be pushed out from the slot 35. Then the push plate 41 is pulled to pull the mounting bracket 4 out from the slide 36. The advertising display board 58 can be taken out from the placement slot 37. After taking it out, the advertising display board 5 to be replaced is put into the placement slot 37 and the mounting bracket 4 is reinserted into the slide 36.

[0043] The interior of the placement box 6 is fixedly equipped with several partitions 61, which divide the interior of the placement box 6 into several storage slots. The advertising display board 5 is placed inside the storage slots. With the setting of the placement box 6, the advertising display board 5 that needs to be replaced can be conveniently stored without having to find a place to store it.

[0044] A reinforcing rib 13 is welded between each of the two uprights 11 and the base 1. A crossbar 14 is fixedly installed between the two uprights 11. The setting of the reinforcing rib 13 and the crossbar 14 can increase the mechanical structure between the uprights 11 and the base 1 and improve the stability of the device.

[0045] An easily adjustable LED advertising lightbox works on the following principle:

[0046] 1) When the height needs to be adjusted, the locking bolt 9 is loosened first to free the support frame 2 from restraint. At this time, the support frame 2 can be adjusted up and down. After the adjustment is completed, the locking bolt 9 is tightened again. The adjustment is convenient.

[0047] 2) When angle adjustment is required, the ratchet 34 and the locking block 7 allow the lightbox to rotate only upwards. To rotate upwards, simply pull the lightbox 34 upwards. Releasing the ratchet 34 and locking block 7 will limit the lightbox 34's movement. To rotate downwards, pull the lever 73 to disengage the locking block 7 from the ratchet 34, allowing the ratchet 34 to be released and the lightbox to rotate downwards.

[0048] 3) When the advertising display board 5 needs to be replaced, the staff will put their hand into the through groove 37 and push the push plate 41. Then the push plate 41 can be pushed out from the slot 35. Then the push plate 41 can be pulled out from the slide 36. The advertising display board 58 can be taken out from the placement groove 37. After taking it out, the advertising display board 5 to be replaced is put into the placement groove 37, and the mounting bracket 4 is reinserted into the slide 36.

[0049] Compared with the prior art, the present invention has the following advantages:

[0050] This utility model uses locking bolts 9 to lock the support frame 2. The height of the light box 3 can be adjusted simply by loosening the locking bolts 9. The angle of the light box 3 is limited by ratchet 34 and locking block 7, making adjustment very convenient. The advertising display board 5 is secured inside the slide groove 36 by the mounting bracket 4. When replacing, the advertising display board 5 can be taken out by pulling out the mounting bracket 4. The placement box 6 can store the alternating advertising display boards 5, allowing for quick retrieval and replacement, thus ensuring the practicality of the device.
