Unless otherwise specified, all technical terms adopted by the present invention have the same meaning as commonly understood by those of ordinary skill in the art to which the present invention belongs. The terms used in the present invention are only for describing specific implementation modes and are not intended to limit the exemplary implementation modes according to the present invention.

[0044] Embodiment 1

[0045] A foldable simulated sand table, as Figures 1 to 4 shown, includes a first box body 1, a second box body 6, a cover plate 8, a sand table box 7 and a lifting structure.

[0046] The lifting structure includes: a first lifting plate 2-1, a second lifting plate 2-2, a third lifting plate 2-3, a fourth lifting plate 2-4, a first connecting plate 3-1, a second connecting plate 3-2, a bidirectional threaded rod 4 and a rocker 5

[0047] The first box body 1 is a cuboid, and a first groove 1-1 is opened downward on the upper end surface of the first box body 1;

[0048] The second box body 6 is a cuboid, a sand box groove 6-2 is opened downward on the upper end surface of the second box body 6, and a second groove 6-1 is opened upward on the lower end surface of the second box body 6.

[0049] In the middle of the inner bottom surface of the first groove 1-1, a first lifting plate 2-1 and a second lifting plate 2-2 are provided, and both the first lifting plate 2-1 and the second lifting plate 2-2 are hinged to the inner bottom surface of the first groove 1-1;

[0050] In the middle of the inner bottom surface of the second groove 6-1, there are a third lifting plate 2-3 and a fourth lifting plate 2-4, and both the third lifting plate 23 and the fourth lifting plate 2-4 are hinged to the inner bottom surface of the second groove 6-1.

[0051] Between the first lifting plate 2-1 and the third lifting plate 2-3, there is a first connecting plate 3-1, and both the first lifting plate 2-1 and the third lifting plate 2-3 are hinged to the first connecting plate 3-1;

[0052] Between the second lifting plate 2-2 and the fourth lifting plate 2-4, there is a second connecting plate 3-2, and both the second lifting plate 2-2 and the fourth lifting plate 2-4 are hinged to the second connecting plate 3-2.

[0053] The first connecting plate 3-1 and the second connecting plate 3-2 are equal in size and the same in shape, and both are provided with threaded through holes at the centers. The bidirectional threaded rod 4 passes through the threaded through holes at the centers of the first connecting plate 3-1 and the second connecting plate 3-2, and both the first connecting plate 3-1 and the second connecting plate 3-2 are threadedly connected to the bidirectional threaded rod 4. One end of the bidirectional threaded rod 4 is provided with a rocker 5;

[0054] The rocker 5 includes a first rod 5-1 and a second rod 5-2. The first rod 5-1 is perpendicularly connected to the bidirectional threaded rod 4. On the side of the first rod 5-1 away from the bidirectional threaded rod 4, there is a second rod 5-2. The second rod 5-2 is hingedly connected to the first rod 5-1. When it is necessary to rotate the bidirectional threaded rod 4, the second rod 5-2 is turned to a position perpendicular to the first rod 5-1, and then the second rod 5-2 is rotated to drive the bidirectional threaded rod 4 to move. After the rotation is completed, the second rod 5-2 is turned to a position close to the first rod, which is convenient for storage and not easily damaged.

[0055] On the side walls of the first box body 1 and the second box body 6 close to the rocker 5, there are openings 21. The inner diameter of the openings 21 is greater than the length of the first rod 5-1. When it is necessary to use the sand table, the second rod 5-2 is turned from the opening 21 to a position perpendicular to the first rod 5-1, and then the second rod 5-2 is rotated to drive the bidirectional threaded rod 4 to move. After the rotation is completed, the second rod 5-2 is turned to a position close to the first rod, so as to protect the rocker 5 when it is not working.

[0056] On the adjacent end faces of the side walls of the first box body 1 and the second box body 6, buffer pads 20 are evenly provided. Through the buffer pads 20, it is avoided that the first box body 1 and the second box body 6 collide when the lifting arm 2 is folded.

[0057] On the end face of the second box body 6 where the sand box groove 6-2 is provided, on one side, a first slot 9 is vertically opened from the outside to the inside, and on the other side, there is a second convex block 17. A groove is provided at the center of the cover plate 8, and the end of the cover plate 8 where the groove is provided is set downward. The groove of the cover plate 8 cooperates with the sand box groove 6-2.

[0058] On one end of the cover plate 8 provided with a groove, a third slot 22 is provided on one side, and a first convex block 14 is provided on the other side. The first convex block 14 is inserted into the first slot 9, and the second convex block 17 is inserted into the third slot 22.

[0059] A second slot 10 is formed on the side wall of the first convex block 14. A first notch 11 is formed at the adjacent position of the first slot 9 and the second slot 10. A second notch 19 is vertically formed at the top of the second groove 6-1. A through hole is formed between the second notch 19 and the first notch 11.

[0060] A disc 15 is provided in the middle of the second notch 19, and the disc 15 is fixedly connected to the second notch 19.

[0061] It further includes a first fixing rod 12 and a second fixing rod 16.

[0062] The first fixing rod includes a chuck 12-1, a first connecting section 12-2 and a first contact end 12-3. The chuck 12-1 is a cone or a frustum of a cone, and the chuck 12-1 is arranged in the second slot 10;

[0063] The first contact end 12-3 is provided with an inclined surface facing downward. The first contact end 12-3 is arranged in the second notch 19. A first connecting section 12-2 is arranged between the first contact end 12-3 and the chuck 12-1. The first connecting section 12-2 is a cylinder, and the first connecting section 12-2 is arranged in the first notch 11 and the through hole. A first spring 13 is sleeved on the outer side of the part of the first connecting section 12-2 in the first notch 11.

[0064] The second fixing rod 16 includes an extrusion block 16-1, a second connecting section 16-2 and a second contact end 16-3. The second contact end 16-3 is provided with an inclined surface facing upward. The second contact end 16-3 is arranged in the second notch 19, above the disc 15. The inclined surface on the second contact end 16-3 is complementary to the inclined surface on the first contact end 12-3.

[0065] The second contact end 16-3 is connected to the extrusion block 16-1 through the second connecting section 16-2. The second connecting section 16-2 passes through the disc 15. A second spring 18 is sleeved on the outer side of the part of the second connecting section 16-2 between the disc 15 and the extrusion block 16-1.

[0066] When the sand table is not needed, the cover plate 8 is buckled above the second box body 6. The first convex block 14 is inserted into the first slot 9, and the second convex block 17 is inserted into the third slot 22;

[0067] The bidirectional threaded rod 4 can be adjusted through the rocker 5, so that the first lifting plate 2-1, the second lifting plate 2-2, the third lifting plate 2-3 and the fourth lifting plate 2-4 descend and move along the bidirectional threaded rod 4 to both sides until the third lifting plate 2-3 abuts against the extrusion block 16-1.

[0068] The extrusion block 16-1 moves upward, and the second spring 18 is compressed under the cooperation of the disc 15.

[0069] The second contact end 16-3 moves upward and abuts against the first contact end 12-3. Since the contacting surfaces of the first contact end 12-3 and the second contact end 16-3 are inclined planes, the first contact end 12-3 moves away from the second notch 19, and the first spring 13 is compressed, thereby driving the chuck 12-1 to insert into the second slot 10, so that the cover plate 8 is fixed above the second box body 6, and at the same time, the second box body 6 contacts the first box body 1;

[0070] Twist the second rod 5-2 to a position close to the first rod 5-1 to complete the folding.

[0071] When a demonstration is needed, adjust the height of the sand table. Adjust the second rod 5-2 to a position perpendicular to the first rod 5-1, and then rotate the second rod 5-2 to adjust the height between the first box body 1 and the second box body 6. During the process, the third lifting plate 2-3 no longer abuts against the extrusion block 16-1, the second spring 18 returns from the compressed state, the second contact end 16-3 moves downward away from the first contact end 12-3, and the first spring 13 returns from the compressed state, thereby driving the chuck 12-1 away from the second slot 10. Then pull out the first convex block 14 from the first slot 9, pull out the second convex block 17 from the third slot 22, and remove the cover plate 8 from above the second box body 6, and the sand table box 7 is exposed, so as to conduct a demonstration.

[0072] Embodiment 2

[0073] A method for using a foldable simulation sand table specifically includes the following steps:

[0074] Before a simulation demonstration is needed, it is necessary to lift the height of the sand table. Rotate out the second rod 5-2 from the inside of the rocker 5, and rotate the second rod 5-2 to drive the bidirectional threaded rod 4 to rotate. The first connecting plate 3-1 and the second connecting plate 3-2 threadedly connected to its outer surface will move towards each other. When the first connecting plate 3-1 and the second connecting plate 3-2 move, they will drive the hinged first lifting plate 2-1, second lifting plate 2-2, third lifting plate 2-3 and fourth lifting plate 2-4 to move towards the center of the bidirectional threaded rod 4. The position of the first box body 1 remains unchanged, and the height of the second box body 6 is increased until it stops rotating the rocker 5 when it reaches the required position;

[0075] After the third lifting plate 2-3 rotates, it no longer squeezes the extrusion block 16-1. At the same time, the second spring 18 generates a thrust on the disc 15 and the second fixed rod 16. Since the disc 15 is fixedly connected inside the second notch 19, when the second spring 18 pushes the second fixed rod 16 out of the second notch 19, the second contact end 16-3 moves downward accordingly and no longer contacts the first contact end 12-3, and the fixing effect on the first fixed rod 12 is also released. Thus, the first fixed rod 12 can move. Pulling up the cover plate 8, the second slot 10 moves upward, and the inclined surface in the second slot 10 pushes the first fixed rod 12 inward to squeeze the first spring 13, and the cover plate 8 can be opened, so as to carry out simulated marketing display teaching.

[0076] As is known by technical common sense, the present invention can be implemented by other embodiments without departing from its spiritual essence or essential features. Therefore, the above-disclosed embodiments are illustrative in all aspects and not exclusive. All changes within the scope of the present invention or equivalent to the present invention are encompassed by the present invention.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the above embodiments, those of ordinary skill in the art should understand that: the specific implementation manners of the present invention can still be modified or equivalently replaced, and any modification or equivalent replacement without departing from the spirit and scope of the present invention should be covered by the protection scope of the claims of the present invention.
