Technical Field

[0001] The present invention relates to the technical field of display devices, and particularly to a multi-directional display device. Background Art

[0002] Art works are works that arouse people's love, including physical works such as sculptures, handicrafts, and art crafts, etc. When exhibiting physical art works, display devices are often needed to display the art works. However, the common display devices in the prior art can only perform fixed display, cannot display all-round to people around, and cannot change the different directions and angles of the art works to display to people, resulting in limited display effects. Moreover, when there is no need for display, the art works are exposed outside and are easily damaged by external forces, affecting subsequent display work. Summary of the Invention

One end of the linkage rod 62 is hinged inside the hemispherical shield 61, and the other end of the linkage rod 62 is hinged to the outer side of the circular drive plate 2;

[0024] When the circular drive plate 2 extends upward, the hemispherical shield 61 opens outward. When the circular drive plate 2 retracts downward, the hemispherical shield 61 closes inward;

[0025] The inclination component 7 includes an arc-shaped sliding seat 71, a second telescopic rod 72, a connecting ball head 73, a ball bowl seat 74 and a reversing component 75. The arc-shaped sliding seat 71 slides along the annular chute 31 at the bottom of the cylindrical box body 3. The outer end face of the arc-shaped sliding seat 71 is provided with a second telescopic rod 72 and a reversing component 75. The reversing component 75 is used to change the position of the arc-shaped sliding seat 71 in the annular chute 31. The telescopic end of the second telescopic rod 72 is fixedly connected with a ball bowl seat 74. The connecting ball head 73 is fixedly connected to the bottom of the sliding sleeve 12, and the connecting ball head 73 is hinged inside the ball bowl seat 74;

[0026] The reversing component 75 has a direction motor 751, a gear 752 and a gear ring 753. The gear ring 753 is arranged on one side of the annular chute 31. The direction motor 751 is fixed to the outer end face of the arc-shaped sliding seat 71. The output end of the direction motor 751 is fixedly connected with a gear 752, and the gear 752 meshes with the gear ring 753. The direction motor 751 can drive the arc-shaped sliding seat 71 to slide in the annular chute 31 through the gear 752 and the gear ring 753;

[0027] The rotation component 8 includes a rotation motor 81 and a friction wheel 82. The rotation motor 81 is fixedly connected to the outer wall of the sliding sleeve 12. The output shaft of the rotation motor 81 is fixedly connected with a friction wheel 82. The outer edge of the friction wheel 82 abuts against the outer edge of the sliding rod 11, and the friction wheel 82 is used to drive the sliding rod 11 to rotate;

[0028] The extension rod 5, the sliding rod 11 and the sliding sleeve 12 are coaxial;

[0029] The diameter of the circular display table 1 is smaller than the diameter of the circular drive plate 2;

[0030] The end face of the display table has a plurality of positioning holes for fixing artworks;

[0031] Through the above settings, in the actual working process, the specific working principle is as follows:

[0032] Before the display, first start the first telescopic rod 4 to extend, so that the first telescopic rod 4 drives the circular drive plate 2 to extend upward. During this process, since a linkage rod 62 is hinged between the hemispherical shield 61 and the circular drive plate 2, the hemispherical shield 61 spreads outwards when the circular drive plate 2 extends upward (as shown in Figure 2 the state shown), and at the same time, the display platform at the top of the positioning ball head 9 extends upward, so as to be unobstructed by the hemispherical shield 61. The sliding rod 11 at the bottom of the positioning ball head 9 extends out of the sliding sleeve 12, and then the art work to be displayed is fixed on the display platform;

[0033] During the display, start the rotation motor 81 to drive the friction wheel 82 to rotate. The rotating friction wheel 82 drives the sliding rod 11 to rotate by abutting against the outer edge of the sliding rod 11. Due to the connection characteristics of the ball head and the ball bowl, the sliding rod 11 drives the circular display platform 1 to rotate during the rotation process through the extension rod 5, so as to synchronously drive the art work fixed on the circular display platform 1 to rotate;

[0034] When tilting the circular display platform 1, control the second telescopic rod 72 to extend to drive the distance that the ball head seat moves to one side, so as to change the tilt angle of the circular display platform 1; during the extension process of the second telescopic rod 72, since the connecting ball head 73 at the bottom of the sliding sleeve 12 is hinged in the ball head seat, the ball head seat drives the circular display platform 1 to tilt through the sliding sleeve 12, the sliding rod 11 and the extension rod 5 during the movement process, so as to drive the art work fixed on the circular display platform 1 to change the tilt angle;

[0035] When changing the tilt direction of the circular display platform 1, start the direction motor 751 fixed on the outer end face of the arc-shaped sliding seat 71. The direction motor 751 drives the gear 752 to rotate. Since the gear 752 meshes with the tooth ring 753 on one side of the annular chute 31, the direction motor 751 can drive the arc-shaped sliding seat 71 to slide along the annular chute 31. Since the second telescopic rod 72 is fixedly connected with the arc-shaped sliding seat 71, the second telescopic rod 72 can drive the ball head seat to rotate around the axis of the cylindrical box body 3. The ball head seat changes the tilt direction of the circular display platform 1 during the rotation process;

[0036] When it is necessary to protect the art work after the display is completed, start the first telescopic rod 4 to contract, so that the first telescopic rod 4 drives the circular drive plate 2 to retract downward into the cylindrical box body 3. During this process, since a linkage rod 62 is hinged between the hemispherical shield 61 and the circular drive plate 2, the two hemispherical shields 61 are driven by the circular drive plate 2 to move closer and close inward (as shown in Figure 1 the state shown), and the sliding rod 11 at the bottom of the positioning ball head 9 retracts into the sliding sleeve 12. At the same time, the display platform at the top of the positioning ball head 9 retracts downward into the cylindrical box body 3, so as to be blocked and protected by the two hemispherical shields 61;

[0037] The above are only embodiments of the present invention, and do not thereby limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall equally be included within the patent protection scope of the present invention.
