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.

[0027] Example 1:

[0028] Please see Figure 1-5 The present invention will describe the above technical solution in detail through the following embodiments:

[0029] A billboard that is easy to replace advertisements includes:

[0030] Advertising box 1 includes a base box 11 and a front cover 12. The base box 11 has a light box 15 inside. The light box 15 has mounting components 2 on both sides. The mounting components 2 include lifting components and fixing components. Each of the lifting components and fixing components is connected to a suspension component 3. The suspension components 3 are connected to an advertising cloth 4. The lifting components are used to drive the suspension components 3 to move in the vertical direction and can adjust the spacing of the suspension components 3.

[0031] Once the lightbox 15 is operational, it can provide illumination and increase the brightness of the advertising banner 4.

[0032] The top of the front cover 12 is rotatably connected to the top of the bottom box 11 via a hinge. Telescopic rods 14 are rotatably installed on both sides inside the bottom box 11, and the top of the telescopic rods 14 is rotatably connected to the inside of the front cover 12.

[0033] The telescopic rod 14 can be a known gas spring support rod. The elastic force of the telescopic rod 14 can support the front cover 12, so that the front cover 12 can be maintained at a certain angle when it rotates upward.

[0034] The bottom surface of the front cover 12 is fixedly connected to the bottom surface of the base box 11 via a movable connector 13.

[0035] The movable connector 13 can be a snap or a pin.

[0036] The front cover 12 has a rectangular through hole running through it from front to back, and the size of the rectangular through hole is smaller than that of the light box 15.

[0037] The through-hole in the middle of the front cover 12 can be fitted with transparent materials such as glass or plexiglass to protect the internal advertising cloth 4.

[0038] The rectangular through-hole is smaller than the light box 15, which can cover the mounting component 2 and the hanging component 3, improving the aesthetics.

[0039] The fixing component includes two first buckles 21. An adjusting plate 22 is fixedly connected to the bottom of the first buckles 21 by adjusting bolts 23. The adjusting plate 22 is fixedly connected to the bottom surface inside the base box 11.

[0040] After the adjusting bolt 23 is tightened, the first clip 21 and the adjusting plate 22 cannot be moved.

[0041] The adjusting plate 22 has a waist-shaped through hole in the middle, and the adjusting bolt 23 can slide along the waist-shaped through hole.

[0042] After the adjusting bolt 23 is loosened, the adjusting bolt 23 can move along the axis of the adjusting plate 22, thereby changing the height of the first buckle 21.

[0043] The lifting assembly includes two synchronous belts 25, which are rotatably mounted on both sides of the light box 15 and located directly above the first buckle 21 via a drive assembly. The drive assembly is used to drive the two synchronous belts 25 to rotate simultaneously in the same direction.

[0044] The drive assembly includes four synchronous pulleys 24, which are symmetrically installed on the left and right sides of the light box 15. A synchronous belt 25 wraps around two of the synchronous pulleys 24.

[0045] A power source 26 is fixedly installed between the two synchronous pulleys 24 on the top surface of the light box 15. The power source 26 is simultaneously engaged with the two synchronous pulleys 24 via a drive shaft 27.

[0046] The power source 26 uses a DC motor with a worm gear reducer. When the power source 26 is working, it can drive the two synchronous pulleys 24 above it to rotate simultaneously in the same direction and at the same speed via the transmission shaft 27. When the synchronous pulleys 24 rotate, they can drive the synchronous belts 25 on both sides to rotate.

[0047] The front side of the timing belt 25 is fitted with a second buckle 28, and the two second buckles 28 are at the same height.

[0048] When the timing belt 25 rotates, it can drive the second latch 28 to move in the vertical direction.

[0049] The suspension assembly 3 includes a pivot 31, with the upper pivot 31 engaging with the second buckle 28 and the lower pivot 31 engaging with the first buckle 21. Two clamps 32 are rotatably mounted on the pivot 31, and the clamps 32 are used to hold the advertising cloth 4.

[0050] The inner side of the clamping plate 32 is provided with interlocking teeth 33, and the interlocking teeth 33 on the two clamping plates 32 interlock with each other. The outer side of the clamping plate 32 is threaded with a fixing screw 34, which can pass through the outer clamping plate 32 and the advertising cloth 4 and be threadedly connected to the inner clamping plate 32.

[0051] After the fixing screw 34 is tightened, it can drive the two clamping plates 32 to approach each other and thus clamp the advertising cloth 4.

[0052] After the rotating shaft 31 is engaged, controlling the synchronous belt 25 to rotate upward can drive the two rotating shafts 31 to move away from each other, thereby unfolding the advertising cloth 4.

[0053] Controlling the synchronous belt 25 to rotate downwards can drive the upper suspension assembly 3 to descend, making it easier to release the engagement between the rotating shaft 31 and the first buckle 21 and the second buckle 28.

[0054] In this embodiment, when the operator uses this device, the movable connector 13 is released from its fixation, the front cover 12 is rotated upward, and the telescopic rod 14 is used to support the front cover 12.

[0055] The power source 26 is controlled to operate, driving the synchronous belt 25 to rotate downwards, which in turn drives the upper suspension assembly 3 to descend.

[0056] Once the upper suspension assembly 3 has been lowered to the appropriate height, the engagement between the pivot 31 and the first buckle 21 and the second buckle 28 can be released, allowing the old advertising cloth 4 and the two suspension assemblies 3 to be removed.

[0057] Loosen the fixing screw 34 to release the clamp 32 from holding the advertising cloth 4.

[0058] Remove the old advertising cloth 4, use the clamp 32 to hold the new clamp 32, and then engage the rotating shaft 31 with the first buckle 21 and the second buckle 28.

[0059] The power source 26 is controlled to operate, driving the synchronous belt 25 to rotate upwards, which in turn drives the upper suspension assembly 3 to rise. The advertising cloth 4 is then unfurled.

[0060] After the advertising cloth 4 is unfolded, observe its unfolded state. If the advertising cloth 4 is not flat enough, loosen the adjusting bolt 23 and adjust the height of the first buckle 21 on both sides to adjust the flatness of the advertising cloth 4.

[0061] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
