Detailed implementation manner

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0038] Refer to Figures 1 - 3 , an embodiment provided by the present invention: a novel mechanical rotating display device, including a placing table 1, a rotating assembly 3 is arranged at the bottom end of the inner wall of the placing table 1, a support assembly 2 is arranged on the surface of the placing table 1, and a 4 is arranged at the bottom end of the placing table 1, and 4 includes a support base 41.

[0039] Refer to Figures 2 - 3 , a sliding column 42 penetrates and is slidably connected to the inner wall of the top end of the support base 41, and the top end of the outer wall of the sliding column 42 is fixedly connected to the bottom end of the outer wall of the placing table 1. By moving the sliding column 42 up and down in the inner wall of the support base 41, the entire placing table 1 can be pushed up and down, so that the height of the display device can be adjusted according to people of different heights. The limiting wheel 47 is rotatably connected to the outer wall of the support base 41. Multiple tooth blocks are arranged on the outer arc surface of the limiting wheel 47 and are the same as the arc surface of the top end of the limiting block 46. A telescopic pedal 43 is rotatably connected to the inner wall of the support base 41. A foot pedal is arranged at the front end of the telescopic pedal 43 and is composed of two rod bodies sleeved with each other. By stepping on it, it can be telescoped, so that the sliding column 42 can be pushed up in the inner wall of the support base 41.

[0040] Refer to Figures 2 - 3, the rotation center axis of the telescopic pedal 43 is fixedly connected with a limit wheel 47. When the telescopic pedal 43 rotates up and down under stepping pressure, it will drive the limit wheel 47 to rotate synchronously with it. A support rod 44 is fixedly connected to the bottom surface of the support base 41. The inner wall of the top end of the support rod 44 is elastically connected with a limit block 46 through a return spring 45. The surface of the limit block 46 is provided with an anti-slip pedal, through which it is convenient to move the limit block 46. One end of the return spring 45 is fixedly connected to the bottom end of the outer wall of the limit block 46, and the other end of the return spring 45 is fixedly connected to the inner wall of the top end of the support rod 44. The function of the return spring 45 is to automatically reset the position of the arc surface at the top of the limit block 46 after being squeezed and moved. The limit wheel 47 is rotatably connected to the outer wall of the support base 41. Two groups of support blocks are provided on the outer wall of the support base 41 to support the rotation positions of the telescopic pedal 43 and the limit wheel 47. The limit block 46 penetrates and is slidably connected to the inner wall of the top end of the support rod 44. Multiple groups of tooth blocks are provided on the outer arc surface of the limit wheel 47. The outer wall of the top end of the limit block 46 is in contact with the outer wall of the tooth blocks of the limit wheel 47. The contact between the two makes the arc surface of the limit wheel 47 connected to the center axis of the telescopic pedal 43 rotate counterclockwise when the telescopic pedal 43 is stepped down, and squeeze the arc surface of the limit block 46 to make the limit block 46 move downward in the inner wall of the support rod 44. When reaching the next group of tooth blocks of the limit wheel 47, the limit block 46 will be elastically acted upon by the return spring 45 and restored to its initial position, so as to contact the back surface of the current tooth block of the limit wheel 47, thereby preventing the limit wheel 47 from rotating in the reverse direction.

[0041] Refer to Figure 1 and Figure 4 , the support assembly 2 includes a fixed disk 21. The fixed disk 21 is rotatably connected to the inner wall of the top end of the placement table 1. Two straight grooves are opened at the top end of the fixed disk 21. The bottom end of the positioning block 26 penetrates and is slidably connected to the inner wall of the straight groove of the fixed disk 21. When the guide disk 22 rotates, the inner wall of the inclined groove on its surface will drive the bottom ends of the two positioning blocks 26 to move towards each other in the inclined groove. At the same time, the positioning block 26 moves in the inner wall of the straight groove of the fixed disk 21, so that the two positioning blocks 26 can only move horizontally, thereby fixing the equipment to be displayed on its surface and preventing it from falling off during the display process. The guide disk 22 is rotatably connected to the inner wall of the fixed disk 21. Two inclined grooves are opened on the surface of the guide disk 22. The inner wall of the inclined groove of the guide disk 22 is slidably connected with the positioning block 26. By rotating the guide disk 22, the two positioning blocks 26 can be moved in the inclined groove and guided.

[0042] Refer to Figure 4, a connecting block 23 is fixedly connected to the outer arc surface of the guiding disk 22. When the connecting block 23 rotates, it will drive the guiding disk 22 to rotate synchronously with it. The top end of the inner wall of the connecting block 23 is elastically connected to an inserting block 25 through a limiting spring 24. One end of the limiting spring 24 is fixedly connected to the surface of the inserting block 25, and the other end of the limiting spring 24 is fixedly connected to the top end inside the connecting block 23. The function of the limiting spring 24 is to automatically reset the position of the inserting block 25 after it is pulled upward. The inserting block 25 penetrates and is slidably connected to the inner wall of the connecting block 23. Multiple through holes are formed in the outer arc surface of the top end of the fixed disk 21. The bottom end of the outer wall of the inserting block 25 is inserted into the inner wall of the through hole. The insertion between the two fixes multiple positions where the inclined slot of the guiding disk 22 drives the positioning block 26 to move in the straight slot of the fixed disk 21, so that clamping and fixing can be carried out according to objects of different sizes.

[0043] Refer to Figure 1 and Figure 5 , the rotating assembly 3 includes a worm gear 33. The worm gear 33 is rotatably connected to the inner wall of the placing table 1. The worm gear 33 is fixedly connected to the rotation central axis of the fixed disk 21. When the worm gear 33 rotates, it will drive the fixed disk 21 to rotate synchronously with it, so that the object on display can be displayed from multiple angles. A worm 32 is rotatably connected to the inner wall of the placing table 1. A handle 31 penetrates and is rotatably connected to the inner wall of the placing table 1. The outer wall of the worm gear 33 meshes with the worm 32. The rotation central axis of the worm 32 is fixedly connected to the handle 31. When the handle 31 rotates, it will drive the worm 32 to rotate synchronously with it, so that the worm 32 can mesh with the worm gear 33 to drive the fixed disk 21 and the object fixed on its surface to rotate synchronously.

[0044] Working principle: When using this display device and it is necessary to adjust the height of the displayed object, step on the foot pedal at the front end of the telescopic pedal 43. The telescopic pedal 43 is pressed up and down to rotate. The limiting wheel 47 fixedly connected to its rotation central axis will rotate synchronously. When the telescopic pedal 43 is pressed down, the limiting wheel 47 rotates counterclockwise, and the tooth block on its outer arc surface will squeeze the arc surface of the limiting block 46, causing the limiting block 46 to move downward in the inner wall of the support rod 44. When the limiting wheel 47 rotates past a tooth block position, the limiting block 46 will return to its initial position under the elastic action of the return spring 45 and contact the back surface of the current tooth block of the limiting wheel 47 to prevent the limiting wheel 47 from rotating in the reverse direction. As the telescopic pedal 43 is continuously pressed, the sliding column 42 moves upward in the inner wall of the support base 41, thereby pushing the entire placing table 1 upward to achieve adjusting the height of the display device according to people of different heights.

[0045] When it is necessary to display objects of different sizes, place the object to be displayed on the surface of the fixed plate 21. First, pull out the insertion block 25 outward to elastically compress the limit spring 24. At the same time, rotate the connecting block 23, and the connecting block 23 drives the guiding disk 22 to rotate on the inner wall of the fixed plate 21. The inner wall of the inclined groove on the surface of the guiding disk 22 drives the bottom ends of the two groups of positioning blocks 26 to move towards each other in the inclined groove. At the same time, the positioning blocks 26 move horizontally on the inner wall of the straight groove of the fixed plate 21, so as to clamp and fix the displayed object. According to the size of the object, after adjusting the position, under the action of the limit spring 24, the bottom end of the outer wall of the insertion block 25 is inserted into the through hole on the outer arc surface of the top end of the fixed plate 21 to fix the position of the guiding disk 22, so as to meet the clamping and fixing requirements of objects of different sizes.

[0046] At the same time, when making multi-angle adjustments to the displayed object, rotate the handle 31. The handle 31 drives the worm 32 to rotate on the inner wall of the placement table 1. The worm 32 meshes with the worm wheel 33, so that the worm wheel 33 drives the fixed plate 21 and the object fixed on its surface to rotate synchronously, realizing multi-angle display of the displayed object.

[0047] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
