DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] like Figure 1-7 As shown, a transient drawing board includes:

[0027] The upper box body 1 is provided with openings at the top and one side. The upper box body 1 is sealed with an upper cover 6 which is slidably sealed on the upper side of the upper box body 1.

[0028] The lower box body 2 is provided with a protrusion on one side of the lower box body 2 close to the upper box body 1, and the protrusion is connected with a rotating shaft 7 and connected to the upper box body 1 through the rotating shaft 7, so that the lower box body 2 can rotate relative to the upper box body 1, so that two different surfaces on the lower box body 2 can be presented, and a fixing block 8 cooperating with the rotating shaft 7 is provided in the upper box body 1, and a mounting hole 12 is provided in the lower box body 1, and a magnet is provided in the mounting hole 12 for fixing display items such as photos and paintings. The upper box body 1 is fixedly connected with a block 15 on the outer wall close to the lower box body 1, and an arc groove 16 is respectively provided on both sides of the lower box body 2 to meet the rotation of the block 15 along the rotating shaft 7, which can limit the rotation angle of the upper box body 1 relative to the lower box body 2.

[0029] The sliding locking device 3 is connected in the upper box body 1 and connected to the lower box body 2, so that the upper box body 1 and the lower box body 2 are limited to each other so that the two cannot be rotated relative to each other through the rotating shaft 7, so that there are two mutually limited points between the lower box body 2 and the upper box body 1.

[0030] The switch 4, the pressing opening abuts against the sliding locking device 3, so that the sliding locking device 3 moves when the switch 4 is pushed, and the connection between the sliding locking device 3 and the lower box body 2 is released. The switch 4 is rotated and connected to the limit shaft 9, and the limit shaft 9 is fixedly connected to the inner bottom of the upper box body 1. The sliding locking device 3 and the switch 4 are respectively provided with a trapezoidal structure block 17 and the two blocks 17 abut against each other, so that when the switch 4 rotates to push the sliding locking device 3 to move, the sliding locking device can produce tangential displacement.

[0031] A fixing hole 10 is provided in the upper cover 6 to satisfy the rotation of the limit shaft 9, and a track 11 is provided at the bottom of the upper cover 6 to satisfy the sliding of the sliding locking device 3. A top block 36 is provided on the top of the slider 31 in the sliding locking device 3 to cooperate with the track 11 for limited sliding, so as to limit the moving direction of the sliding locking device 3. The sliding locking device 3 includes a slider 31, and a receiving hole 32 is provided on the side of the slider 31 away from the lower box body 2. A spring is provided in the receiving hole 32 and the other end of the spring is connected to the inner wall of the upper box body 1, and the spring plays a resetting role. A plug plate 33 is connected to the side of the slider 31 close to the lower box body 2, and the lower box body 2 and the upper box body 1 are jointly provided with two symmetrically arranged slots 34, and the plug plate 33 is inserted into one slot 34, so as to achieve a limiting effect.

[0032] Mounting blocks 13 are respectively provided on both sides of the upper box body 1, and the two mounting blocks 13 are fixedly connected with a rubber band. A through hole 14 is opened through the rotating shaft 7 to allow the rubber band to pass through. When the rotating shaft 7 rotates, the rubber band passing through the through hole 14 will stretch, causing it to generate a tensile elastic force, so that the rotating shaft 7 always has a tendency to reset. A buckle 5 is sleeved on the outer side of the rotating shaft 7. The buckle 5 is installed in the groove opened on the rotating shaft 7 and enables the rotating shaft 7 to be limited and rotatably connected with the fixed block 8, so as to prevent the rotating shaft 7 from detaching from the upper box body 1.

[0033] When the utility model is used: a photo is placed on the reverse side of the lower box body 2, and a magnet is placed on the photo for adsorption, the switch 4 is pressed, and the sliding locking device 3 is pushed to slide, wherein the plug plate 33 in the sliding locking device 3 is withdrawn from the slot 34 of the lower box body 2, thereby unlocking the entire device, and then the lower box body 2 is pushed to rotate, wherein the block 15 rotates 180° just when it reaches the end of the arc groove 16, and the switch 4 is released, and the sliding locking device 3 moves in the opposite direction under the push of the spring elastic force, and enters the slot 34 on the other side of the lower box body 2, thereby locking the lower box body 2, and the rubber band generates tension due to the rotation, and enters the ready state at this time;

[0034] During the performance, a pattern is drawn on the front and placed in front of the audience. The switch 4 is pressed to push the sliding locking device 3 to slide and withdraw from the slot 34 of the lower box body 2. The lower box body 2 rotates around the rotation axis 7 under the action of the rubber band tension to a certain angle. Under the mutual attraction between the magnetic forces of the two magnets installed on the upper box body 1 and the lower box body 2, the rotation is accelerated to 180° and reaches the end of the arc groove 16. After the collision, the rotation stops, and then the switch 4 is released. The sliding locking device 3 is pushed by the spring elastic force to make the plug plate 33 enter the other slot 34 of the lower box body 2, thereby locking the upper box body 1 and the lower box body 2, and presenting the photo on the reverse side of the lower box body 2 to complete the magic show.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
