Display stand for marketing teaching

[0033] The present invention provides a technical solution: a display platform for marketing teaching, including three support columns 11 and a motor frame 21, the upper surfaces of the three support columns 11 are fixedly connected with a support plate 1, and a There are guide grooves 12 and six sliding rods 32 are slidably connected through the guide grooves 12. The upper surfaces of every two sliding rods 32 are fixedly connected with oval gears 3 for double-sided display panels to slide and to facilitate viewing of double-sided display panels. Each elliptical gear 3 is provided with a preliminary fixing mechanism for initially fixing the double-sided display board, and three placement slots 13 are provided on the diagonal of the guide slot 12, and each placement slot 13 is fixedly rotated and connected with a rotating rod 71, each rotating rod 71 is sleeved with a torsion spring 72, and each rotating rod 71 is hinged with a guide block 7 for guiding the slide rod 32 to slide t

[0047] It is basically the same as the first embodiment, furthermore, the support plate 1 is provided with a maintenance mechanism for applying lubricating oil to each oval gear 3, the maintenance mechanism includes an arc-shaped piston cylinder 8, and the support plate 1 is close to the mating plate 14 One end of one end is provided with a receiving groove and is fixedly connected with the arc-shaped piston barrel 8 through the containing groove. The inner wall of the arc-shaped piston barrel 8 is axially slidably connected with an arc-shaped sealing plug 82, and the arc-shaped sealing plug 82 is fixedly connected with a through arc-shaped The arc-shaped piston barrel 8 extends to the arc-shaped piston rod 81 in the placement groove 13 , and the end of the arc-shaped piston rod 81 away from the arc-shaped sealing plug 82 is fixedly connected with the guide block 7 .

[0048] refer to image 3 and Figure 6 When the sliding rod 32 at the front end of the oval gear 3 slides to me
