[0026] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will provide a detailed description of the specific implementation manners of the present utility model in conjunction with the accompanying drawings of the specification.

[0027] Embodiment 1

[0028] Referring to Figures 1-4 , for the first embodiment of the present utility model, a telescopic table for exhibition is provided, including a bottom plate 1. An electric push rod 11 is rotatably connected to the upper side of the bottom plate 1. The electric push rod 11 is externally powered, and the electric push rod 11 can rotate with the bottom plate 1;

[0029] It further includes a load-bearing structure with a telescopic adjustment function provided on the electric push rod 11;

[0030] The load-bearing structure includes a first limit block 21 provided on the electric push rod 11. The first limit block 21 is rotatably connected through an adjusting plate 31, and the adjusting plate 31 is fixed on the electric push rod 11. A first telescopic rod 22 movably connected in the first limit block 21. The size of the first telescopic rod 22 is larger than that of the second telescopic rod 26. A square hole through which the first telescopic rod 22 can just pass is provided in the middle position of the first limit block 21. Second limit blocks 23 fixed at both ends of the first telescopic rod 22. A gear 24 rotatably connected in the second limit block 23. The gear 24 is rotatably connected to the inner side of the second limit block 23 through a shaft body. An adjusting block 25 rotatably connected to the gear 24. The adjusting block 25 is fixed to the shaft body on the gear 24, so that the gear 24 can be adjusted by rotating the adjusting block 25.

[0031] The inner side of the first limit block 21 is movably connected with a second telescopic rod 26. There are two second telescopic rods 26 in total, symmetrically arranged in the two smaller square holes at the upper and lower sides of the first limit block 21. Third limit blocks 27 are fixedly connected to both ends of the second telescopic rod 26. The difference between the third limit block 27 and the second limit block 23 is that only the second limit block 23 and the lower side of the first limit block 21 are provided with round holes 28. A round hole 28 is provided on the lower side of the second limit block 23.

[0032] A toothed plate 29 is movably connected inside the second limiting block 23. There are two toothed plates 29 in a set of connecting columns. The two toothed plates 29 are located in the same plane and perpendicular to each other. The opening positions and directions of the teeth 210 are the same, and a chute is provided on the back of the opening surface of the teeth 210. The toothed plate 29 is fixedly connected with teeth 210, and the toothed plate 29 meshes with the gear 24.

[0033] One side of the toothed plate 29 is provided with nested plates 211. There are two nested plates 211 in a set of connecting columns. They are also perpendicular to each other and in the same plane. And a slide rail that can cooperate with the chute on the toothed plate 29 is fixedly connected to the inner side of the nested plate 211. A clamping block 212 is fixedly connected to the nested plate 211. When the device is tightened, the clamping block 212 will clamp the information board, thereby fixing the information board. A rotating structure is provided on the lower side of the first limiting block 21.

[0034] During the use process, first push the electric push rod 11 to the required height. Then place the information board on the upper part of the bearing structure, and the four corners of the information board need to contact the inner side of the clamping block 212. Then rotate the gear 24. Since the gear 24 meshes with the toothed plate 29, it will drive the toothed plate 29 to move. Due to the function of the second limiting block 23, the movement path of the nested plate 211 is limited and the nested plate 211 cooperates with the chute of the toothed plate 29 through the slide rail. Thus, the toothed plates 29 in contact with each other enter the contacting nested plates 211 driven by the gear 24, thereby adjusting the distance between two adjacent clamping blocks 212 to achieve the effect of adjusting the size of the bearing structure according to the size of the information board. Generally, the gears 24 on the parallel sides need to be adjusted in the same direction at the same time, which can make the process more labor-saving. After adjusting the gears 24 on the two parallel sides, the gears 24 on the other two parallel sides need to be adjusted. Thus, the four corners of the information board are fixed by the clamping blocks 212. When the distance between the clamping blocks 212 changes, the lengths of the first telescopic rod 22 and the second telescopic rod 26 will also change accordingly, mainly playing a supporting role and a connecting role.

[0035] Embodiment 2

[0036] Refer to Figures 1-5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the rotating structure includes an adjusting plate 31 arranged inside the first limiting block 21. A rotating shaft 36 is fixedly connected to the inner side of the adjusting plate 31. The rotating shaft 36 is located in the circular hole 28 of the first limiting block 21. An installation plate 32 fixed on the electric push rod 11, a first connecting block 33 rotatably connected to the installation plate 32. There is a shaft body inside the installation plate 32, and the first connecting block 33 is rotatably connected to the installation plate 32 through this shaft body. A third telescopic rod 34 fixed on the first connecting block 33. The third telescopic rod 34 is an electric telescopic rod, and its length can be adjusted by an external power supply.

[0037] On one side of the third telescopic rod 34, a second connecting block 35 is fixedly connected. Inside the second connecting block 35, a rotating shaft 36 is fixedly connected. The second connecting block 35 is rotationally connected to the first limiting block 21 through the inner rotating shaft 36.

[0038] During use, the shaft body inside the adjusting plate 31 is the main rotating shaft, and the third telescopic rod 34 is the power rod. The two third telescopic rods 34 cooperate with each other to contract and extend, enabling the bearing structure to rotate through the rotating shaft 36 inside the adjusting plate 31. During this process, the first connecting block 33 is located in the mounting plate 32 to provide support for the bearing structure, and the second connecting block 35 provides the connection between the third telescopic rod 34 and the bearing structure, making the connection and adjustment more stable.

[0039] The remaining structures are the same as those in Embodiment 1.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
