The utility model provides a print platform, including print platform 1, place board 2, electro-magnet 3, iron plate 4 down, go up iron plate 5, spring 6, screw 7, it fixes on print platform 1 to go up iron plate 5, and electro-magnet 3 and iron plate 4 down are fixed respectively and are being placed the different positions on board 2, go up iron plate 5 and correspond with mutual perpendicular down between the iron plate 4, when electro-magnet 3 circular telegram, electro-magnet 3 passes to iron plate 4 down with magnetism, and attract and go up iron plate 5, thereby with print platform 1 and place and fix mutually between the board 2. Simultaneously, go up iron plate 5 and pass through 6 fixed connection of spring on print platform 1, the accessible adjusts the flexible distance of spring 6, adjusts print platform 1's height to adjust print platform 1's levelness.

The utility model provides a place board 2 and be equipped with two, electro-magnet 3, lower iron plate 4, go up iron plate 5, spring 6 all are equipped with four, go up iron plate 5 and fix in print platform 1's four corners department, fix on placing board 2 with lower iron plate 4 that last iron plate 5 corresponds perpendicularly, electro-magnet 3 is fixed at the both ends of placing board 2, place board 2 and fix in the workbin of 3D printer to establish under print platform 1, with print platform 1 swing joint.

The printing platform 1 is provided with a first screw hole 11 (not shown in the figure), the upper iron block 5 comprises a sixth screw hole 51 and a concave hole 52, the diameter of the sixth screw hole 51 is smaller than the inner diameter of the concave hole 52, and the sixth screw hole 51 is communicated with the concave hole 52; the screw 7 passes through the first screw hole 11 and is screwed with the sixth screw hole 51, so that the upper iron block 5 is fixedly connected with the printing platform 1.

The external diameter of spring 6 is less than the internal diameter of shrinkage pool 52, spring 6 cover is established on screw 7, and establish in the shrinkage pool 52 of last iron plate 5 and between print platform 1, when last iron plate 5 is fixed on print platform 1, screw 7 screws, spring 6 contracts because of the pressure between print platform 1 and the shrinkage pool 52 bottom, make the relative position of going up iron plate 5 and print platform 1 more nearly, loose screw 7, spring 6 stretches, make the relative position of going up iron plate 5 and print platform 1 farther.

Place board 2 and make for metal material, including boss 21, second screw 22 and third screw 23, the one side of placing board 2 is equipped with two outstanding boss 21 in placing board 2 plane, be equipped with second screw 22 on the boss 21, the both ends of placing board 2 are equipped with third screw 23, electro-magnet 3 is fixed on placing board 2 through third screw 23, lower iron plate 4 is fixed on placing board 2 through second screw 22, and lower iron plate 4 corresponds with last iron plate 5 mutually perpendicular, the out of plumb corresponds between print platform 1 and the electro-magnet 3, namely, pass through the electricity with electro-magnet 3 after the magnetism transmission for lower iron plate 4, thereby attract last iron plate 5, stagger each other between print platform 1 and the electro-magnet 3, print platform 1 can not be arranged in on electro-magnet 3.

Specifically, the electromagnet 3 is provided with a fourth screw hole 31, and a screw passes through the third screw hole 23 and is screwed with the fourth screw hole 31, so that the electromagnet 3 is fixed on the placing plate 2. The lower iron block 4 comprises a fifth screw hole 41, a round hole 42 and a concave platform 43, the three are in a stepped structure, specifically, the diameter of the fifth screw hole 41 is smaller than the inner diameter of the round hole 42, the fifth screw hole 41 is communicated with the round hole 42, the inner diameter of the round hole 42 is smaller than the inner diameter of the concave platform 43, the round hole 42 is communicated with the concave platform 43, a screw passes through the fifth screw hole 41 and the second screw hole 22, the lower iron block 4 is fixed on the placing plate 2, and the end head of the screw is placed in the round hole 42.

Go up the external diameter of iron plate 5 and be less than the internal diameter of concave station 43, after 3 circular telegrams of electro-magnet, lead iron plate 4 down through placing board 2 with magnetism, lower iron plate 4 corresponds with last iron plate 5 mutually perpendicular to attract to go up iron plate 5, go up iron plate 5 and fix in concave station 43, spacing last iron plate 5 prevents to go up iron plate 5 and removes. When electro-magnet 3 did not switch on, iron plate 4 did not have magnetism down, can not attract upper iron plate 5, then print platform 1 can with place the board 2 phase separation, realize print platform 1's dismantling.

Place board 2 and fix in the workbin of 3D printer through the lead screw to remove in the workbin under the guide effect of guide bar, it is specific, place board 2 including the lead screw hole 24 that is used for passing the lead screw and two guide holes 25 that are used for passing the guide bar, the lead screw is connected with the motor, drive the lead screw after the motor rotates, make the rotation of placing board 2 accessible lead screw and the direction of guide bar remove in the workbin, thereby drive print platform 1 and remove.

Because electro-magnet 3 highly is too high, the utility model discloses in will be down iron plate 4 and electro-magnet 3 fix stagger in the position of placing board 2 and place, with electro-magnet 3 magnetism through placing board 2 conduction to iron plate 4 down, can avoid print platform 1 like this and place the distance between board 2 too big, shorten the distance of placing between board 2 and the print platform 1, reduce the inner space of 3D printer, be favorable to the miniaturization of 3D printer.

The detailed description of the embodiments of the present invention has been presented above, and it will be apparent to those skilled in the art that the present invention can be modified and improved without departing from the principles of the present invention, and the modifications and improvements also belong to the protection scope of the claims of the present invention.
