Problems solved by technology

[0004] (1) The technical problem to be solved by the present invention is: most of the supporting surfaces of existing educational propaganda devices are fixed structures, which are inconvenient to expand the space. Changing the angle of publicity and the position of the center of gravity of the entire display device, the stability is poor, and most of them are simple plane structures with very limited viewing angles

Embodiment 1

[0046] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 with Figure 13 As shown, this embodiment proposes a propaganda device that is convenient for expanding space, including a main support base 1, and a side end surface of the main support base 1 is provided with a secondary support base 2, and the secondary support base 2 is away from the main support A side rib clamping assembly 3 is provided on one side of the seat 1, and two bridge-shaped connecting assemblies 5 for expanding space and supporting functions are provided on the rear end surface of the side rib clamping assembly 3, and the two bridge-shaped connecting assemblies 5 A plurality of connecting columns 6 are arranged on the opposite surface of the connecting component 5, and a radian regulating component 7 is arranged between the connecting column 6 and the main support seat 1, and a center of gravity...

Embodiment 2

[0048] The scheme in embodiment 1 is further introduced below in conjunction with specific working methods, see the following description for details:

[0049] Such as figure 1 , figure 2 , image 3 , Figure 5 , Image 6 , Figure 10 with Figure 13 As shown, as a preferred embodiment, on the basis of the above method, further, the main support base 1 and the auxiliary support base 2 are clamped with a limiting component 4 for ensuring the stability of the promotional paper, and the limiting component 4. It includes traveling connecting cylinders 401. Three passing connecting cylinders 401 are clamped on the top of the main support base 1 or the two auxiliary supporting bases 2. The ports on the top of the passing connecting cylinders 401 are connected to the first outer housing through pins 403. The outer arc surface of the sleeve 402 is hinged, and the first outer connecting sleeve 402 is covered with a first inner telescopic frame 404, and one end of the first inner...

Embodiment 3

[0058] The schemes in Embodiment 1 and Embodiment 2 are further introduced below in conjunction with specific working methods, see the following description for details:

[0059] Specifically, when this kind of publicity device that is convenient for expanding space is working / using:

[0060] Step S1: Insert the lever into the plug-in connection port 802, and lift the drive shaft 801 until the second movable magnetic base 134 is attracted to the second fixed magnetic base 135. Engagement occurs between the first inner dense teeth 507, and then the direction and the number of rotations of the toggle lever are controlled according to the extent of the expansion space. The drive shaft 801 will use the first driving dense teeth 803 and the first inner dense teeth during the rotation process. The linkage effect between the inner dense teeth 507 will act on the third adapter barrel 505, so that the third adapter barrel 505 drives the second linkage gear 504 to rotate in the third be...

Abstract

The invention relates to a propaganda device convenient for space expansion. The propaganda device comprises a main supporting seat, wherein an auxiliary supporting seat sleeves the side end surface of the main supporting seat, and a side rib clamping assembly sleeves the side surface, deviating from the main supporting seat, of the auxiliary supporting seat. Through mutual cooperation of a gravity center regulation and control assembly, a linkage assembly, a radian regulation and control assembly, a limiting assembly and other structures, good viewing effect is obtained even if the device is viewed at an angle deviating from the center; the radian of a curved-surface display panel can guarantee that distances between the panel and eyes are equal, and therefore, the curved-surface display panel can bring better sensory experience, the visual field of learners is increased, and watching is prevented from being affected by increase of a display area; the forward movement of a balancing weight is used for regulating and controlling the gravity center position of the whole device, so the stability of the whole display device is effectively ensured; and the single-side display area of education propaganda paper is expanded, so flexibility is high, the use of the device is convenient, and a proper display surface can be provided as required.

Description

technical field [0001] The present invention relates to the field of education and teaching, in particular to a publicity device, and further to a publicity device that facilitates space expansion. Background technique [0002] However, most of the existing educational propaganda devices have a fixed support surface, which is not convenient for expanding the space. Even if the function of expanding the space is realized, it is impossible to quickly change the propaganda angle of view and the center of gravity of the entire display device according to the needs of use. The stability is poor, and most of them are simple planar structures with very limited viewing angles. [0003] Therefore, we improve this and propose a promotional device that is convenient for expanding the space. Contents of the invention [0004] (1) The technical problem to be solved by the present invention is: most of the supporting surfaces of existing educational propaganda devices are fixed structu...
