Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 The present invention provides an LED advertising lightbox that facilitates the replacement of advertising boards, comprising a lightbox body 1, wherein the interior of the lightbox body 1 is provided with a hollow groove 6, and a placement plate 5 is pulled out and disposed inside the hollow groove 6, and two support components are symmetrically arranged on both sides of the lightbox body 1.

[0022] The rear end of the light box body 1 is symmetrically provided with multiple sliding grooves 7. The back of the placement plate 5 is provided with a slider 8 that passes through the sliding grooves 7 and slides with the sliding grooves 7. The rear end of the light box body 1 is symmetrically provided with two driven shafts 11. A rotating shaft 9 is rotatably provided between the two driven shafts 11. A driven shaft 11 is fixedly provided on the rotating shaft 9. The driven shaft 11 meshes with the slider 8. Positioning plates 12 are fixedly provided at both ends of the rotating shaft 9. The positioning plates 12 are located outside the positioning seat 10. Two support rods 13 are symmetrically provided on both sides of the light box body 1. The support rods 13 are provided with a second limiting rod 14 for limiting the positioning plate 12. The second limiting rod 14 is threadedly connected to the support rod 13.

[0023] In this embodiment, the advertising board can be attached to the placement plate 5, and the placement plate 5 is placed in the empty slot 6, so that the advertising board can be displayed inside the light box body 1.

[0024] When the advertising board needs to be replaced, rotate the second limiting rod 14 so that one end of the second limiting rod 14 does not contact the positioning plate 12. At this time, the second limiting rod 14 will not limit the positioning plate 12. Then, pull the placement plate 5 so that the placement plate 5 can be pulled out in the empty groove 6. During this process, the slider 8 will slide in the slide groove 7, and through the meshing action, the slider 8 can drive the driven shaft 11 to rotate, which in turn can drive the rotating shaft 9 to drive the two positioning plates 12 to rotate. When the placement plate 5 descends to the designated position, rotate the second limiting rod 14 to lock the positioning plate 12, which can fix the position of the placement plate 5. Then the advertising board can be removed from the placement plate 5. This process does not require disassembling the multiple screws on the light box body 1. When the advertising board is replaced, the placement plate 5 is located below the light box body 1, which makes the advertising board easy to disassemble.

[0025] When the initial position of the light box body 1 is high, it will be difficult for the placement plate 5 to be pulled out of the empty slot 6. The support assembly includes a first branch pipe 2 and a second branch pipe 3. The first branch pipe 2 can be inserted into the interior of the second branch pipe 3, and the top of the second branch pipe 3 is provided with a first limiting rod 4 for limiting the first branch pipe 2. The first limiting rod 4 is threadedly connected to the second branch pipe 3. When the initial position of the light box body 1 is high, the first limiting rod 4 is rotated so that the first limiting rod 4 will not limit the first branch pipe 2. At this time, the first branch pipe 2 can be lowered into the second branch pipe 3, which can further reduce the height of the light box body 1, making it easier to grab the placement plate 5, thereby making it easier to pull out of the empty slot 6.

[0026] In this embodiment, the cross-section of the groove 7 is T-shaped.

[0027] The lack of a limiting structure on the light box body 1 for the placement plate 5 makes it easy for the placement plate 5 to be completely pulled out of the empty slot 6. Multiple limiting seats 17 are fixedly installed at the rear end of the light box body 1, located at the bottom of the light box body 1. A spring is installed in the limiting seat 17, and a buffer block 16 is installed on the top of the spring. A limiting plate 15 is installed at the bottom of the light box body 1. The limiting plate 15 can contact the buffer block 16. When the placement plate 5 is about to be completely pulled out, the limiting plate 15 will contact the buffer block 16, which will compress the spring. The spring and the buffer block 16 can provide a buffering effect at the limiting plate 15, which can reduce the impact force at the limiting plate 15. The limiting plate 15 can prevent the placement plate 5 from being completely pulled out of the empty slot 6.

[0028] In this embodiment, one end of the first limiting rod 4 and the second limiting rod 14 are provided with anti-slip pads. The anti-slip pads are made of rubber. The anti-slip pads can increase the friction between the first limiting rod 4 and the first branch pipe 2 and the friction between the second limiting rod 14 and the positioning plate 12.
