However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and complete.

[0019] For examples, please refer to Figure 1-4 This utility model provides a technical solution: A movable reusable signboard includes a display column 1. A forward and reverse motor 101 is embedded in the front side of the top of the display column 1. The output end of the forward and reverse motor 101 passes through the interior of the display column 1 and is connected to a drive screw 102. A screw sleeve 103 is threaded onto the outer side of the drive screw 102. A slide rail assembly 104 extending along the height direction of the display column 1 is embedded in the rear side of the display column 1. A movable base 2 is slidably sleeved on the outer side of the display column 1. A connecting screw hole 201 is opened inward on the front side of the movable base 2 and at the four corners. An assembly plate 3 is provided on the front side of the movable base 2. Locking bolts 301 are rotatably connected to the corners inside the assembly plate 3. A mounting bracket 302 is fixed on the front side of the assembly plate 3. A signboard frame 4 is fixed on the front side of the mounting bracket 302.

[0020] The slide rail assembly 104 includes a slide rail and a slide block. The front and rear sides of the inner side of the movable seat 2 are fixedly connected to the screw sleeve 103 and the slide block by bolts, respectively, so that the movement is more stable. The movable base 2 and the assembly plate 3 are designed to be detachable. The locking bolt 301 and the connecting screw hole 201 are locked and fixed by threads, which makes it easy to replace the sign frame 4. A control switch is installed on the outside of the display column 1. The control switch is connected to the forward and reverse motor 101 by a wire, and the connection is electrical.

[0021] In this embodiment, a transparent display window 401 is provided on one side of the signboard frame 4, a rectangular opening 402 is provided horizontally at the top of the signboard frame 4, a waist-shaped groove 403 is provided vertically at the front side of the signboard frame 4, a connecting vertical seat 404 is slidably provided at the front end of the inner side of the signboard frame 4, an adjusting screw 405 is provided at the bottom of the outer side of the connecting vertical seat 404, which passes through the waist-shaped groove 403, and a locking nut 406 is threadedly connected to the outer side of the adjusting screw 405. The top of the connecting vertical seat 404... A pull rod 407 is provided inward. A fixing sleeve with an abutment plate 408 is provided inside the vertical base 404 and outside the pull rod 407. A pressure spring 409 is connected between the top left and right sides of the abutment plate 408 and the inside of the vertical base 404. A connecting block 410 is provided inside the vertical base 404. A fixing hole 411 for cooperating with the pull rod 407 is opened on the top of the connecting block 410. A display board 412 is provided on the rear side of the connecting block 410. The external structural size of the connecting vertical base 404 and the display board 412 is adapted to the internal structural size of the signboard frame 4. The top of the connecting vertical base 404 is provided with a through hole for the pull rod 407 to move up and down. The connecting vertical base 404 and the connecting plug 410 are connected in a separable structure by plugging and unplugging.

[0022] The working process of this utility model is as follows: When the movable reusable signboard or structure designed in this scheme needs to be replaced during operation, loosen the adjusting screw 407 and the locking nut 406. Move the connecting vertical seat 404 upward inside the waist-shaped slide groove 403, so that the display letter board 412 also moves upward. The display letter board 412 is usually made of foam plastic board, which is relatively lightweight. Then, pull the pulling rod 407 upward, so that the abutment plate 408 drives the pressure spring 409 to retract. The pulling rod 407, which was originally inserted into the fixing hole 411 in the connecting plug 410, is disengaged, and the connecting plug 410 can be removed. Then, replace it with a new display letter board 412, and put the corresponding end of the connecting plug 410 back on. Continue to insert it into the connecting vertical seat 404 for fixation, and finally put it back into the letter frame 4 so that the font can be displayed in the transparent display window 401. Compared with disposable letter display racks, it greatly improves the use value and reuse rate, and the display height of the displayed letter 412 can be adjusted. By starting the forward and reverse motor 101 to drive the rotation of the drive screw 103, the thread drives the rotation of the screw slide sleeve 103. With the assistance of the slide rail assembly 104, the height of the movable seat 2 can be adjusted up and down, which improves its practicality. When the letter frame 4 is damaged, the connection between the locking bolt 301 and the connecting screw hole 201 can be removed to separate the movable seat 2 from the assembly plate 3, so as to facilitate the replacement of the letter frame 4.
