Based on the above explanation, the tray 31 can move up and down in the containing chamber 101.
As shown in fig. 4, when the exhibit is displayed, the tray 31 needs to move upwards in the accommodating cavity 101, and the tray 31 will give way to the tongue depressor 35, so that the tongue depressor 35 has the freedom to move upwards.
After the tray 31 moves in the way, under the elastic force of the compression spring 34, the pressing tongue 35 moves upwards, the pressing tongue 35 drives the friction strip 36 to move upwards, the friction strip 36 moves upwards to drive the fourth friction wheel 37 to rotate, the fourth friction wheel 37 rotates to drive the partition plate 38 to slide in the sliding groove 102, and the two partition plates 38 move away from each other to allow the tray 31 to pass through the accommodating cavity 101.

The rotation of the first internal spline tube 7 can synchronously drive the external spline tube 11 to rotate, and the rotation of the external spline tube 11 drives the reciprocating threaded tube 12 and the first friction wheel 13 to rotate.
Before exhibition of the exhibit is carried out, the following operations are required:
the driving baffle 47 compresses the return spring 48, at this time, the sliding rod 45 will slide in the sliding sleeve 46, and the sliding rod 45 drives the second braking member 44 to move synchronously during the sliding process again until the second braking member 44 abuts against the first friction wheel 13.
The second brake piece 44 is abutted against the first friction wheel 13 to enable the first friction wheel 13 to perform deceleration movement, the reciprocating threaded pipe 12 is decelerated along with the first friction wheel 13 due to the fact that the reciprocating threaded pipe 12 is fixedly connected with the first friction wheel 13, the speed of the reciprocating threaded pipe 12 is reduced while the speed of the external spline pipe 11 is kept unchanged, the reciprocating threaded pipe 12 and the external spline pipe 11 perform relative movement, the reciprocating threaded pipe 12 is in threaded connection with the external spline pipe 11, at the moment, the external spline pipe 11 performs reciprocating movement in the axial direction, and the reciprocating movement enables the external spline pipe 11 to move in the vertical direction.
When the external spline tube 11 vertically moves to the highest point, the second braking element 44 is separated from the first friction wheel 13, and the bearing plate 33 and the tray 31 are also exposed from the accommodating cavity 101, so as to display the exhibit.
When the external spline tube 11 moves vertically to the lowest point, the second brake piece 44 is separated from the first friction wheel 13, so that the bearing plate 33 and the tray 31 can be positioned in the accommodating cavity 101 again to accommodate the exhibits.
When the exhibit is displayed, the tray 31 needs to move upwards in the accommodating cavity 101, and the tray 31 will give way to the tongue depressor 35, so that the tongue depressor 35 has the freedom degree of moving upwards.
After the tray 31 is moved away, under the elastic force of the compression spring 34, the pressing tongue 35 moves upwards, the pressing tongue 35 drives the friction strip 36 to move upwards, the friction strip 36 moves upwards to drive the fourth friction wheel 37 to rotate, the fourth friction wheel 37 rotates to drive the partition plate 38 to slide in the sliding groove 102, and the two partition plates 38 are separated from each other, so that the tray 31 can pass through the accommodating cavity 101.
When the exhibit is stored, the tray 31 only needs to move downwards in the containing cavity 101, downward pressure is applied to the pressing tongue 35 in the downward moving process of the tray 31, the pressing tongue 35 moves downwards after being stressed to drive the friction strip 36 to move downwards, the friction strip 36 drives the fourth friction wheel 37 to rotate reversely, the two partition plates 38 are connected in an abutting mode, and the two connected partition plates 38 seal the containing cavity 101 to prevent the exhibit from being polluted by external impurity and dust.

Rotation of the planetary gear 10: the planetary gear 10 rotates to drive the second internal spline tube 9 to rotate, the second internal spline tube 9 rotates to drive the spline shaft 21 to rotate, the spline shaft 21 rotates to drive the third bevel gear 23 to rotate, the third bevel gear 23 rotates to drive the fourth bevel gear 25 to rotate, the fourth bevel gear 25 rotates to drive the third internal spline tube 24 to rotate, the third internal spline tube 24 rotates to drive the reciprocating screw 19 to rotate, the reciprocating screw 19 rotates to drive the fifth bevel gear 27 to rotate, the fifth bevel gear 27 rotates to drive the sixth bevel gear 28 to rotate, the sixth bevel gear 28 rotates to drive the short shaft 29 to rotate, the short shaft 29 rotates to drive the second friction wheel 30 to rotate, the second friction wheel 30 rotates to drive the third friction wheel 32 to rotate, and the third friction wheel 32 rotates to drive the bearing plate 33 to rotate.
When the bearing plate 33 rotates, the exhibits placed on the bearing plate 33 also rotate along with the bearing plate, so that the audience presents each position of the exhibits to the audience under the condition that the position of the audience is not changed, and the watching experience of the audience is improved.
The air bag 43 is extruded, the air bag 43 is communicated with the cylinder 14 through the connecting pipe 39, the pressure of the cylinder 14 is increased after the air bag 43 is extruded, the plunger 15 moves upwards in the cylinder 14 under the action of the pressure, and the plunger 15 drives the first braking piece 16 to move upwards synchronously until the first braking piece 16 abuts against the internal threaded pipe 18.
Based on the above embodiment 1, it can be seen that the reciprocating screw 19 can rotate, and during the rotation, the reciprocating screw can drive the internally threaded tube 18 to rotate synchronously.
When the first braking member 16 abuts against the internally threaded tube 18, the internally threaded tube 18 is decelerated, and after the internally threaded tube 18 is decelerated, the speed is different from the reciprocating screw 19, that is, relative rotation is generated between the reciprocating screw 19 and the internally threaded tube 18.
The reciprocating screw rod 19 and the internal threaded pipe 18 rotate relatively, the reciprocating screw rod 19 will reciprocate in the horizontal direction, and the reciprocating screw rod 19 will drive the tray 31 and the bearing plate 33 to synchronously move horizontally.
Based on the above embodiment 1, it is known that the bearing plate 33 can perform revolution, and the horizontal movement of the bearing plate 33 changes the radius of the revolution.
When the exhibition is carried out, a plurality of students can sit around the table plate 1, the exhibits are placed on the bearing plate 33, and the revolution radius of the bearing plate 33 is changed to move the exhibits from the middle of the table plate 1 to the front of each student, so that the students can watch the exhibits at a close distance.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
