[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Example 1, by Figure 1-2 As shown, this utility model includes two support columns 1, which are arranged parallel to each other. A folding mechanism 2 is installed between the two support columns 1, and a display plate 4 is provided between the two support columns 1. A base plate 13 is fixedly installed at the bottom end of the support column 1, and a side groove 5 is provided at the top end of the support column 1. A limiting mechanism 3 is installed inside the side groove 5.

[0028] Specifically, by Figure 3-5 The folding mechanism 2 includes two support plates 201 fixed to the adjacent sides of two pillars 1. Each support plate 201 has a placement groove 204 on its top, on which the display board 4 is placed. Each support plate 201 has a movable plate 202 rotatably connected to its bottom. A connecting plate 203 is provided between the two pillars 1. The adjacent sides of the two movable plates 202 are rotatably connected to the connecting plate 203. A U-shaped rod 2014 is fixedly installed at the bottom of the connecting plate 203. Two sliders 2016 are symmetrically and movably sleeved on the outer side of the U-shaped rod 2014. Insert rods 207 are fixedly installed on the opposite sides of the two sliders 2016. Base blocks 2013 are fixedly installed at the bottom of each of the two movable plates 202. Insert holes 2017 are provided on the adjacent sides of the two base blocks 2013. The two insert rods 207 pass through the U-shaped rod 2014 and are inserted into the two insertion holes 2017 respectively. Inside 17, magnet 1 205 and magnet 2 206 are fixedly installed on the side of the two support plates 201 that are close to each other. Magnet 1 205 and magnet 2 206 have opposite magnetic properties. A sleeve plate 2015 is fixedly installed at the bottom of the connecting plate 203. The sleeve plate 2015 is fixedly sleeved on the middle of the outer side of the U-shaped round rod 2014. The sleeve plate 2015 is located between the two sliders 2016. Two guide rods 209 are symmetrically fixedly installed at the bottom of the sleeve plate 2015. The same screw sleeve 2012 is movably sleeved on the outer side of the two guide rods 209. Two movable rods 208 are symmetrically rotatably connected to the outer side of the screw sleeve 2012. The ends of the two movable rods 208 away from the screw sleeve 2012 are rotatably connected to the two sliders 2016 respectively. A screw rod 2011 is rotatably connected to the bottom of the sleeve plate 2015. A turntable 2010 is fixedly installed at the bottom end of the screw rod 2011. The screw sleeve 2012 is threadedly sleeved on the outer side of the screw rod 2011.

[0029] In the initial state of use, the display board 4 is placed on the two placement slots 204, and the two insert rods 207 are respectively inserted into the two insertion holes 2017. The distance between the two support pillars 1 remains fixed. When it is necessary to carry the support pillars 1 and the display board 4, first remove the display board 4 from between the two support pillars 1, then rotate the turntable 2010 to drive the screw 2011 to rotate, and drive the screw sleeve 2012 to slide down along the two guide rods 209. Then, through the two movable rods 208, drive the two sliders 2016 to slide along the U-shaped round rod 2014. At the same time, the two insert rods 207 move closer to each other until they are separated from the two insertion holes 2017. At this time, the fixation between the two movable plates 202 and the connecting plate 203 is released. Then, the two support pillars 1 are moved and moved closer to each other until the magnet 1 205 and the magnet 206 are in contact. Since the magnets 1 205 and 206 have opposite magnetism, they attract each other, thus fixing the two support pillars 1 after they move closer to each other. Finally, the volume of the entire bracket is reduced for easy carrying.

[0030] Specifically, by Figure 6 The limiting mechanism 3 includes a support shaft 301 rotatably connected within the side groove 5. A column 302 is fixedly mounted on the top of the support shaft 301, and a top plate 309 is fixedly mounted on the top of the column 302. A movable plate 303 is movably sleeved on the outer side of the column 302. Two connecting columns 3010 are symmetrically fixedly connected to the top of the movable plate 303. The tops of the two connecting columns 3010 penetrate the top plate 309 and are fixedly connected to the same top plate 307. Both connecting columns 3010 are connected to the top plate 309. 09 Movable connection, a handle 305 is fixedly installed on the top of the top plate 307, a limit rod 308 is fixedly installed on the bottom of the top plate 307, a top rod 306 is fixedly installed on the top of the support column 1, the top plate 307 is sleeved on the outside of the top rod 306, two limit holes 7 are symmetrically provided on the top of the display plate 4, and the two limit rods 308 are respectively inserted into the two limit holes 7. A spring 304 is fixedly connected between the movable plate 303 and the top plate 309, and the spring 304 is sleeved on the outside of the column 302;

[0031] In use, initially, the top plate 307 is located inside the side groove 5. First, pull the handle 305 upward to raise the top plate 307. Through the two connecting columns 3010, the movable plate 303 slides upward along the column 302. At this time, the spring 304 is compressed. When the bottom height of the top plate 307 is greater than the top height of the top rod 306, the top plate 307 is rotated by a certain angle through the handle 305 so that the top plate 307 is fitted on the outside of the top rod 306. Then, release the control of the handle 305. At this time, the spring 304 resets and drives the movable plate 303 to slide downward along the column 302. Through the two connecting columns 3010, the top plate 307 moves downward until the limiting rod 308 is inserted into the limiting hole 7 to limit the display plate 4. Finally, the display plate 4 is fixed between the two support columns 1.

[0032] Specifically, by Figure 7 The bottom of the base plate 13 is symmetrically and fixedly connected to two base columns 14. The bottom end of each base column 14 is provided with a caster wheel 6. A lifting plate 15 is movably sleeved between the two base columns 14. A limit plate 16 is fixedly connected to the bottom of the lifting plate 15. The bottom of the limit plate 16 is provided with multiple anti-slip particles to increase its friction with the ground. Two springs 8 are symmetrically and fixedly connected between the lifting plate 15 and the base plate 13. The two springs 8 are respectively sleeved on the outside of the two base columns 14. Two rotating shafts 9 are symmetrically and rotatably connected to the top of the lifting plate 15. The top ends of the two rotating shafts 9 pass through the base plate 13 and are fixedly connected to a top block 12. An outer frame 10 is fixedly sleeved on the outside of the support column 1. The two top blocks 12 are located on the top of the outer frame 10. Two positioning rods 11 are symmetrically and fixedly connected to the top of the outer frame 10. The two top blocks 12 are respectively sleeved on the outside of the two positioning rods 11.

[0033] In the initial state, the caster 6 is in contact with the ground, while the limiting plate 16 is not in contact with the ground. The second spring 8 is in a compressed state, and the support column 1 can be moved by the caster 6 to realize the transfer of the entire device. When the entire device is in the required position, firstly, the two top blocks 12 on the top of the outer frame 10 are moved upward, and the lifting plate 15 is driven to slide upward along the two bottom columns 14 through the two rotating shafts 9. At this time, the second spring 8 is compressed again until the two top blocks 12 are separated from the outside of the two positioning rods 11 respectively. Then, the two top blocks 12 are rotated until they are removed from the top of the outer frame 10. Then, the two top blocks 12 are released. At this time, the second spring 8 is reset and drives the lifting plate 15 to move downward. At the same time, the limiting plate 16 descends until it is in close contact with the ground to prevent the support column 1 from moving arbitrarily. Finally, the entire device is fixed to achieve the stable placement of the display board 4 for publicity.
