[0021] like Figure 1-4 As shown, an adjustable poster stand comprises a base 1, an adjustment component 2 and a poster stand body 3, the adjustment component 2 is arranged on the base 1, the poster stand body 3 is movably arranged on the adjustment component 2, the adjustment component 2 comprises a limit rod 4, a limit slide groove 5, a stud 6, a threaded slide seat 7, a turning handle 23 and an angle adjustment member 8, the limit rod 4 is symmetrically arranged on both sides of the base 1, the limit slide groove 5 is arranged on the limit rod 4, the lower end of the stud 6 is rotatably arranged on the inner bottom wall of the limit slide groove 5, the upper end of the stud 6 passes through the threaded hole at the top of the limit rod 4 and extends upward, the turning handle 23 is arranged at the upper end of the stud 6, the threaded slide seat 7 is slidably arranged in the limit slide groove 5, the threaded slide seat 7 is threadedly connected to the stud 6 through an internal thread, the angle adjustment member 8 is arranged between two symmetrical threaded slide seats 7, and the poster stand body 3 is arranged on the angle adjustment component 2.

[0022] like Figure 2-4 As shown, in order to quickly adjust the angle of the poster frame body 3, the angle adjustment assembly 2 includes a left connecting member 9 and a right connecting member 10, and the left connecting member 9 and the right connecting member 10 are respectively fixedly connected to the two sides of the poster frame and the threaded slide 7. The left connecting member 9 includes a threaded seat 11, a screw rod 12, an insert block 13 and a connecting block 14. The left end of the threaded seat 11 is fixedly connected to the side wall of the threaded slide 7, one end of the screw rod 12 is threadedly connected to the internal thread cavity of the threaded seat 11, and the other end of the screw rod 12 is fixedly connected to the insert block 13. The connecting block 14 is fixedly connected to the poster frame body 3, and the connecting block 14 is provided with a plug-in screw near the plug-in screw 13. The groove of the block 13 matches the groove, and the plug-in block 13 is movably plugged into the internal groove of the connecting block 14. The plug-in block 13 and the groove are both rectangular. The right connecting piece 10 includes a connecting block 2 15, a plug-in rod 16 and a spring 17. The connecting block 2 15 is fixedly arranged on the right side of the poster frame body 3. A cylindrical groove is provided on the side of the connecting block 2 15 away from the poster frame body 3. One end of the plug-in rod 16 is fixedly connected to the threaded slide 7, and the other end of the plug-in rod 16 is movably plugged into the cylindrical groove on one side of the connecting block 2 15. The spring 17 is sleeved on the outside of the plug-in rod 16, and the spring 17 is arranged between the connecting block 2 15 and the threaded slide 7.

[0023] Among them, the connecting block 14 and the connecting block 2 15 are symmetrically arranged, the four corners of the lower surface of the base 1 are fixed with sleeves 18, the bottom opening of the sleeve 18 is internally threaded with a threaded rod 19, and the bottom of the threaded rod 19 is provided with an anti-slip pad 20, the poster frame body 3 is a hollow setting with an opening on one side, and a movable door 21 is hingedly provided at the opening on one side of the poster frame body 3, and a storage groove 22 is opened on the upper surface of the base 1, and the storage groove 22 is arranged below the poster frame body 3.

[0024] When in use, the movable door 21 is opened, and the poster is laid flat in the inner space of the poster rack body 3. The movable door 21 is closed. When adjusting the height of the poster, the handles 23 on both sides of the poster rack body 3 are turned at the same time. The handles 23 drive the studs 6 to rotate, and the threaded slide 7 rotates with the studs 6 and rises upward along the limiting slide groove 5. The left connecting member 9 and the right connecting member 10 connected to the threaded slide 7 drive the poster rack body 3 to rise. If the height needs to be lowered, the handles 23 are turned in the opposite direction.

[0025] When the poster display angle needs to be adjusted, the connection block 15 and the plug rod 16 are pushed in the direction of each other, the spring 17 contracts, the plug rod 16 enters deep into the connection block 15, and the plug block 13 on the other side of the poster frame body 3 is separated from the connection block 14. The plug block 13 is held and rotated to the required angle. The plug block 13 drives the screw 12 to rotate in the threaded seat 11. After the poster frame body 3 is rotated to the required angle along the plug rod 16, the connection block 15 and the plug rod 16 are pushed again to insert the plug block 13 into the groove on the connection block 14. Because the plug block 13 and the groove are both rectangular, they cannot be rotated after being plugged in, so they are fixed. In order to save costs and ensure the stability of this application, the poster frame body 3 is made of lightweight materials;

[0026] When the ground is uneven, the length of the threaded rod 19 inserted into the sleeve 18 is adjusted to make the base 1 level. Adjusting the connection length between the threaded rod 19 and the sleeve 18 can also assist in adjusting the height of the poster stand.

[0027] Although the embodiments of the utility model have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the utility model, and the scope of the utility model is defined by the attached claims and their equivalents. In short, if those skilled in the art are inspired by them and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the scope of protection of the utility model.
