[0021] 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.

[0022] Please see Figure 1-4 An adjustable banner includes a base 1, a support column 2 connected to the top of the base 1, and a threaded rod 3 fixedly connected to the bottom of the support column 2. The top of the base 1 has a threaded hole 4 matching the threaded rod 3. Two bases 1 are placed on the ground, and the support column 2 is threadedly connected to the base 1. The top of the support column 2 has a sliding cavity 5, and an extension rod 6 is slidably connected inside the sliding cavity 5. A limit bolt 13 passes through the upper end of the outer wall of the support column 2, and the limit bolt 13 is threadedly connected to the support column 2. One end of the limit bolt 13 abuts against the outer wall of the extension rod 6. The extension rod 6 is slidably slid upwards to adjust to a suitable height, and the limit bolt 13 is tightened to fix the extension rod 6, thus making the banner height adjustment convenient. A connecting plate 7 is slidably connected to the upper end of the outer wall of the extension rod 6, and a T-shaped slider 8 is fixedly connected to one side of the connecting plate 7. A threaded hole 4 matching the T-shaped slider 8 is opened on the upper end of the outer wall of the extension rod 6. The T-shaped slide groove 9 matches the extension rod 6. The upper end of the extension rod 6 is threadedly connected to the top cover 10. When installing the connecting plate 7, the T-shaped slider 8 on one side of the connecting plate 7 is inserted into the T-shaped slide groove 9 on the extension rod 6, and then the top cover 10 is threadedly connected to the extension rod 6. This can provide a good fixing effect for the connecting plate 7. The other side of the connecting plate 7 is connected to the connector 11. The other end of the connector 11 is connected to the frame 12. Multiple frames 12 are connected to each other through the connector 11. The connecting plate 7, the extension rod 6, and the frame 12 can all be detached, making it convenient for people to assemble and disassemble the banner. The top of the frame 12 has an opening. The banner lettering is inserted into the frame 12 through the opening at the top of the frame 12, and the banner can be used normally. When the banner is no longer needed, the banner lettering inside the frame 12 can be taken out and stored, so that the banner can be reused and the problem of banner waste is solved.

[0023] like Figure 4As shown, the connector 11 includes a connecting block 14. Both ends of the connecting block 14 are provided with slots 15 that match the connecting plate 7 and the frame 12. One side of the inner wall of the slot 15 is fixedly connected with a buckle 16, and the other side of the inner wall of the slot 15 is provided with a buckle groove that matches the buckle 16. The connecting plate 7 and the frame 12 are provided with multiple through holes 17 that match the buckles 16. When people install the frame 12, they snap the connecting plate 7 and the frame 12 into the slots 15 on the connecting block 14, press the buckles 16 on the connecting block 14 so that they pass through the connecting plate 7 and the frame 12 and snap into the buckle groove on the connecting block 14. This not only makes it easier for people to disassemble and reassemble the banner, but also makes the banner more stable during use.

[0024] like Figure 3 As shown, a symmetrical guide block 18 is fixedly connected to the lower end of the outer wall of the extension rod 6. A guide groove 19 matching the guide block 18 is opened on the inner wall of the slide cavity 5. When the extension rod 6 slides inside the slide cavity 5, the guide block 18 at the lower end of the outer wall of the extension rod 6 and the guide groove 19 on the inner wall of the slide cavity 5 can play a good role in limiting and guiding the extension rod 6, thereby making the extension rod 6 more stable when sliding inside the slide cavity 5, and effectively preventing the extension rod 6 from leaving the slide cavity 5, thus effectively ensuring the normal operation of the device.

[0025] like Figure 1 As shown, the outer wall of the extension rod 6 has multiple grooves 20 that match the limiting bolts 13, and the grooves 20 are linearly arrayed and equidistantly distributed on the outer wall of the extension rod 6. When the staff adjusts the height of the banner to a suitable level, tightening the limiting bolts 13 can effectively fix the extension rod 6. Through the grooves 20 on the outer wall of the extension rod 6, after tightening the limiting bolts 13, one end of the bolt abuts against the inner wall of the groove 20, which can further improve the stability of the banner during use.

[0026] like Figure 1 As shown, both the connecting plate 7 and the frame 12 are made of acrylic sheet material. Because acrylic sheet material has advantages such as high transparency, lightness, sturdiness, and impact resistance, the connecting plate 7 and the frame 12 are made of acrylic sheet material, which can effectively extend the service life of the banner.

[0027] like Figure 4 As shown, the corners of the connecting block 14 are all rounded. By making the corners of the connecting block 14 rounded, people will not be scratched by the corners of the connecting block 14 when disassembling the banner, thus making it more convenient for people to disassemble the banner.

[0028] like Figure 1As shown, a shaped knob is fixedly connected to one end of the limiting bolt 13, and the outer wall of the shaped knob is fitted with an anti-slip sleeve. When people need to adjust the height of the banner, they need to rotate the limiting bolt 13. Through the shaped knob set at one end of the limiting bolt 13, people can more easily rotate the limiting bolt 13 by rotating the shaped knob. The anti-slip sleeve on the outer wall of the shaped knob can effectively increase the friction between people's hands and the outer wall of the shaped knob, preventing people from slipping when rotating the shaped knob.

[0029] As can be seen from the above, the specific embodiments of this utility model are as follows:

[0030] When using the banner, place the two bases 1 on the ground, then thread the support column 2 onto the base 1, slide the extension rod 6 upwards to adjust it to a suitable height, and tighten the limit bolt 13 to fix the extension rod 6, making it easy to adjust the banner height. When installing the connecting plate 7, insert the T-shaped slider 8 on one side of the connecting plate 7 into the T-shaped groove 9 on the extension rod 6, and then thread the top cover 10 onto the extension rod 6, which can provide a good fixing effect for the connecting plate 7. Secure the connecting plate 7 and the frame 12 into the slots 15 on the connecting block 14, and press the connecting block. The buckle 16 on the 14 allows it to pass through the connecting plate 7 and the frame 12 and engage with the buckle groove on the connecting block 14. This not only makes it easier for people to disassemble the banner, but also makes the banner more stable during use. After the frame 12 is assembled, since there is an opening at the top of the frame 12, the banner lettering can be inserted into the frame 12 through the opening at the top of the frame 12, and the banner can be used normally. When the banner is no longer needed, the banner lettering inside the frame 12 can be taken out and stored, so that the banner can be reused, thereby effectively extending the service life of the banner.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model.
