[0022] Please refer to Figures 1-4. This utility model provides a technical solution: a mobile platform device for a photopolymerization 3D printer, including a base plate 1, an adjustment structure 2 on the base plate 1, and a plurality of fixing structures 3 on the base plate 1;

[0023] The adjustment structure 2 includes a support frame 201, a rotating frame 202, a first pulley 203, a rotating threaded rod 204, a movable plate 205, a guide rod 206, a connecting frame 207, a motor 208, a second pulley 209, and a transmission belt 210. The support frame 201 is mounted on the base plate 1. The rotating frame 202 is movably mounted on the support frame 201. The first pulley 203 is mounted on the rotating frame 202. The rotating threaded rod 204 is movably mounted on the rotating frame 202. The movable plate 205 is movably mounted on the rotating threaded rod 204. The guide rod 206 is mounted on the movable plate 205 and is movably connected to the support frame 201. The connecting frame 207 is mounted on the support frame 201. The motor 208 is mounted on the connecting frame 207. The second pulley 209 is mounted on the drive end of the motor 208. The transmission belt 210 is located on the first pulley 203 and the second pulley 209. The 3D printer is placed on the moving plate 205. When the height of the 3D printer needs to be adjusted, the drive motor 208 is activated. The motor 208 can drive the second pulley 209 to rotate. Under the action of the second pulley 209, the transmission belt 210 drives the first pulley 203 to rotate. The rotating frame 202 rotates on the support frame 201 under the action of the first pulley 203. The rotating threaded rod 204 rotates and moves under the action of the rotating frame 202. The moving plate 205 moves under the action of the rotating threaded rod 204. The guide rod 206 follows the moving plate 205 and moves on the support frame 201, making the moving plate 205 move stably. The moving plate 205 can drive the 3D printer to be adjusted to a predetermined height.

[0024] Furthermore, the support frame 201 is provided with reinforcing ribs, and the guide rod 206 is adapted to the support frame 201. The reinforcing ribs increase the stability of the support frame 201, and the adapted guide rod 206 moves stably on the support frame 201.

[0025] Furthermore, there are several guide rods 206, and the motor 208 is fixed to the connecting frame 207 by bolts. There are four guide rods 206, which are symmetrically and movable in pairs on the support frame 201. The four guide rods 206 make the moving plate 205 more stable when it moves. The motor 208 fixed by bolts is easy to install and remove on the connecting frame 207.

[0026] Furthermore, one of the plurality of fixed structures 3 includes a movable wheel 301, a fixed frame 302, a sliding frame 303, a slot 304, a stop plate 305, a placement frame 306, a slider 307, a rotating threaded rod 308, a mounting frame 309, a rotating frame 310, and an auxiliary wheel 311. The movable wheel 301 is mounted on the base plate 1, the fixed frame 302 is mounted on the base plate 1, the sliding frame 303 is movably disposed on the fixed frame 302, and the slot 304 is disposed on the sliding frame. On frame 303, the abutment 305 is mounted on the sliding frame 303, the placement frame 306 is mounted on the fixed frame 302, the slider 307 is movably mounted on the placement frame 306, the rotating threaded rod 308 is movably mounted on the placement frame 306 and is movably connected to the slider 307, the mounting frame 309 is mounted on the fixed frame 302, the rotating frame 310 is movably mounted on the mounting frame 309, and the auxiliary wheel 311 is movably mounted on... Mounted on the rotating frame 310, with the auxiliary wheel 311 abutting against the slider 307, the movable wheel 301 can drive the entire device to move. After moving to a predetermined position, the distance between the sliding frame 303 and the fixed frame 302 is adjusted so that the abutment plate 305 abuts against the placement plane, and the movable wheel 301 moves away from the placement plane. The device remains stable during operation. Rotating the threaded rod 308 allows it to rotate and move on the placement frame 306. Under the action of the threaded rod 308, the slider 307 moves on the placement frame 306. The auxiliary wheel 311 rotates under the action of the slider 307. The end of the rotating frame 310 with the auxiliary wheel 311 rotates away from the placement frame 306 under the action of the slider 307. The end of the rotating frame 310 away from the auxiliary wheel 311 moves towards the placement frame 306 until the end of the rotating frame 310 away from the auxiliary wheel 311 enters the slot 304 in the sliding frame 303. The rotating frame 310 can restrict the sliding frame 303 to prevent it from moving during operation and ensure the stability of the device during operation.

[0027] Furthermore, the card slots 304 are provided in several places, and the placement frame 306 is provided with reinforcing ribs. The card slots 304 are equally spaced on the sliding frame 303. The card slots 304, together with the rotating frame 310, can fix and limit the sliding frame 303 at different positions. The reinforcing ribs increase the stability of the placement frame 306.

[0028] Furthermore, the rotating threaded rod 308 is provided with a rotating handle at the end away from the slider 307, and the slot 304 is adapted to the rotating frame 310. The rotating handle can easily drive the rotating threaded rod 308 to rotate, and the matching slot 304 and the rotating frame 310 cooperate to make the sliding frame 303 more stable.

[0029] Furthermore, the end of the abutment 305 away from the sliding frame 303 is provided with anti-slip texture, and the bottom plate 1 is provided with a push frame. The anti-slip texture increases the friction when the abutment 305 contacts the placement surface, and the push frame facilitates the movement of the pushing device.

[0030] Working principle: When the height of the 3D printer needs to be adjusted, the drive motor 208 drives the second pulley 209 to rotate. The transmission belt 210, under the action of the second pulley 209, drives the first pulley 203 to rotate. The rotating frame 202 rotates on the support frame 201 under the action of the first pulley 203. The rotating threaded rod 204 rotates and moves under the action of the rotating frame 202. The moving plate 205 moves under the action of the rotating threaded rod 204. The guide rod 206 follows the moving plate 205 on the support frame 201, making the moving plate 205 move stably. The moving plate 205 can drive the 3D printer to adjust to the predetermined height. The moving wheel 301 can drive the entire device to move. After the entire device moves to the predetermined position, the distance between the sliding frame 303 and the fixed frame 302 is adjusted so that the support plate... 305 abuts against the placement plane, causing the moving wheel 301 to move away from the placement plane, thus maintaining stability during operation. Rotating the threaded rod 308 allows it to rotate and move on the placement frame 306. The slider 307 slides on the placement frame 306 under the action of the threaded rod 308. The auxiliary wheel 311 rotates under the action of the slider 307. The end of the rotating frame 310 with the auxiliary wheel 311 rotates away from the placement frame 306 under the action of the slider 307. The end of the rotating frame 310 away from the auxiliary wheel 311 moves towards the placement frame 306 until the end of the rotating frame 310 away from the auxiliary wheel 311 enters the slot 304 in the sliding frame 303. The rotating frame 310 can restrict the sliding frame 303 to prevent it from moving during operation, ensuring the stability of the device during operation.
