Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] See also Figure 1-5 As shown, a propaganda stand with easily replaceable advertising paper comprises a propaganda stand body 1, the front and rear sides of the propaganda stand body 1 are fixedly connected with a first card plate 2, a second card plate 3 is provided on the upper inner side of the propaganda stand body 1, the interiors of the first card plate 2 and the second card plate 3 are provided with a limiting structure 4 for fixing the advertising paper, a fixed plate 5 is fixedly connected to the middle position of the propaganda stand body 1, the interior of the fixed plate 5 is rotatably connected with a bidirectional screw 6, both sides of the surface of the bidirectional screw 6 are threadedly connected with movable blocks 7, one side of the movable block 7 is fixedly connected with a third card plate 8, a force-applying structure 9 for driving the bidirectional screw 6 to rotate is provided inside the rear of the fixed plate 5, a vertical plate 10 is fixedly connected to the top of the fixed plate 5, a threaded rod 11 is internally threaded at the other end of the vertical plate 10, one end of the threaded rod 11 is fixedly connected to a turntable 12, and the other end of the threaded rod 11 is rotatably connected to the bottom of the second card plate 3.
[0025] The limiting structure 4 includes a folding rod 41, a limiting disk 42 and a spring 43. Both ends of the folding rod 41 are movably connected to the inside of the first clamping plate 2. Both ends of the folding rod 41 are fixed to one side of the two limiting disks 42. The spring 43 is sleeved on the surface of the folding rod 41. Both ends of the spring 43 are respectively fixed between the limiting disk 42 and the inner wall of the first clamping plate 2. In this way, with the elastic force of the spring 43 itself, the limiting disk 42 can be driven to always move toward the surface of the advertising paper, thereby facilitating the limiting of the advertising paper.
[0026] The force-applying structure 9 includes a torsion plate 91, a rotating rod 92, a first bevel gear 93 and a second bevel gear 94. The torsion plate 91 is arranged on the outside of the fixed plate 5, and one side of the torsion plate 91 is fixed to one end of the rotating rod 92. The other end of the rotating rod 92 extends to the interior of the fixed plate 5 and is fixed to one side of the first bevel gear 93. The interior of the second bevel gear 94 is fixed to the surface of the bidirectional screw 6, and one side of the first bevel gear 93 is meshed with one side of the second bevel gear 94. In this way, when driving the bidirectional screw 6 to rotate, the torsion plate 91 can be rotated, and the rotating rod 92 and the first bevel gear 93 can be driven to rotate, while driving the second bevel gear 94 to rotate, thereby driving the bidirectional screw 6 to rotate.
[0027] Slide grooves 13 are provided on the top of both sides of the inner cavity of the promotional stand body 1. Both sides of the second clamping plate 3 are slidably connected to the inside of the slide grooves 13, so that the second clamping plate 3 can be auxiliary limited to facilitate its up and down movement.
[0028] The upper and lower parts of the inner side of the promotional stand body 1 are fixedly connected with connecting plates 14, and movable grooves 15 are provided on both sides of the surface of the connecting plate 14. The interior of the movable groove 15 is slidably connected with a movable block 16, and one side of the movable block 16 is fixed to one side of the third card plate 8, so that the third card plate 8 can be auxiliary supported and the stability of the third card plate 8 can be maintained during movement.
[0029] A handle 17 for applying force to the folding rod 41 is fixedly connected to the surface of the folding rod 41 , so that before placing the advertising paper each time, the folding rod 41 can be pulled outward by applying force through the handle 17 .
[0030] It is worth noting that: the technical features proposed in this technical solution should be regarded as prior art, and the specific structure, working principle, and possible control method and spatial layout method of these technical features can be selected by conventional options in the field, and this technical solution will not further elaborate on them.
[0031] Working principle: When in use, the limiting structure 4 on the surface of the first card board 2 can be pulled outward, and then the bottom surface of the advertising paper can be placed on the inner side of the first card board 2, and then the limiting structure 4 can be released to limit the bottom of the advertising paper. Then the turntable 12 can be rotated to drive the threaded rod 11 to rotate, so that the second card board 3 can move up and down, so that the position can be adjusted according to the length of the advertising paper. After the adjustment is completed, the second card board 3 can limit the top surface of the advertising paper. Then the bidirectional screw 6 can be driven to rotate by the force structure 9, and at the same time, the left and right movable blocks 7 can be driven to move toward or opposite sides, and the third card board 8 can be driven to move together, so that the third card board 8 can limit the two sides of the advertising paper. When the advertising paper is replaced subsequently, the above operation is repeated, first driving the left and right third card boards 8 to move to the opposite side, and then driving the second card board 3 to move upward, and finally the advertising paper can be taken out and replaced.
