Technical Field

[0001] This utility model relates to the field of visual communication technology, and in particular to a foldable, multi-scene adaptable bracket. Background Technology

[0002] Visual communication is an important means of information dissemination. The effectiveness of visual communication largely depends on the display method and the presentation medium. A high-quality display stand can significantly improve the efficiency and attractiveness of visual information transmission, enabling the audience to receive and understand the content more clearly and comfortably.

[0003] To improve the display effect, the visual communication stands currently used are usually designed to be rotatable. For example, the patent application number 201720022272.0 discloses a display stand for visual communication design. However, the above-mentioned stand is an integral structure that cannot be folded when not in use, takes up a lot of space when stored, and has a limited number of items that can be displayed, making it difficult to adapt to different usage scenarios. Summary of the Invention

[0004] This utility model provides a foldable, multi-scenario adaptable bracket, which can increase the number of items that can be displayed, making it easy to adapt to different usage scenarios. When not in use, the support column can be folded up on the top of the main support plate, and the drive shaft can also be disassembled, reducing the space occupied during storage.

[0005] In a first aspect, this utility model provides a foldable, multi-scenario adaptable bracket, specifically comprising: a main support plate; two display trays rotatably mounted on the inner side of the main support plate; four support columns rotatably mounted on the top of the main support plate; four connecting sleeves fixed at the bottom of the main support plate; a drive block rotatably mounted in the middle of the main support plate; a drive shaft mounted on the top of the drive block; and a stepper motor fixed in the middle of the top of the base.

[0006] The bottom of each connecting sleeve is provided with a rectangular opening groove, and the cross-sectional dimensions of the rectangular opening groove are the same as the cross-sectional dimensions of the support column and the vertical rods on both sides of the top of the base.

[0007] The main support plate has two circular opening slots on its top, and the display tray is located directly below the two circular opening slots on the top of the main support plate.

[0008] Each of the drive blocks has a hexagonal block at its bottom, and the top of the drive shaft and the top of the stepper motor spindle each have a corresponding hexagonal slot.

[0009] Each of the drive blocks has a gear on its outer side, and the display tray also has a corresponding tooth groove on its outer side. The gear on the outer side of the drive block meshes with the tooth groove on the outer side of the display tray.

[0010] The drive shaft has two vertical protrusions on its bottom outer wall, and each drive block has a groove on its top that corresponds to the size of the bottom of the drive shaft.

[0011] The support column can rotate on the top of the main support plate. When the support column is rotated to a vertical position, it can also slide up and down. When the support column slides down to the bottom, its bottom end can be embedded in the rectangular grooves on both sides of the top of the main support plate and be in close contact with the inner wall of the rectangular groove.

[0012] This utility model provides a foldable, multi-scenario adaptable bracket, which has the following beneficial effects: Each main support plate in this invention is equipped with two rotatable display trays, which allow for the rotation and display of items.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Example 1: Please refer to Figures 1 to 6 : This utility model proposes a foldable, multi-scene adaptable bracket, including: a main support plate 1; two display trays 2 are rotatably mounted on the inner side of the main support plate 1, the main support plate 1 is used to support the rotation of the display trays 2, and the display trays 2 are used to support the items to be displayed; four support columns 3 are rotatably mounted on the top of the main support plate 1, and four connecting sleeves 4 are fixed to the bottom of the main support plate 1. When the support columns 3 are unfolded, they can support the main support plate 1 located above. The support columns 3 and the vertical rods on both sides of the top of the base 7 cooperate with the connecting sleeves 4 to support the main support plate 1. The support plate 1 provides stable support and prevents it from moving in the horizontal direction; a drive block 5 is rotatably installed in the middle of the main support plate 1, and a drive shaft 6 is installed on the top of the drive block 5. When the drive block 5 rotates, it can drive the display tray 2 to rotate synchronously through the gear on its outer side. The drive shaft 6 cooperates with the drive block 5 to connect the upper and lower adjacent drive blocks 5; the main support plate 1 is installed on the top of the base 7, and a stepper motor 8 is fixed in the middle of the top of the base 7. The base 7 is used to fix the stepper motor 8, and the stepper motor 8 is used to drive the drive block 5 to rotate.

[0018] In this embodiment, as Figures 1-3 As shown, each of the connecting sleeves 4 has a rectangular opening slot at its bottom, and the cross-sectional dimensions of the rectangular opening slot are the same as those of the support column 3 and the vertical rods on both sides of the top of the base 7. When the first main support plate 1 is installed, the vertical rods on both sides of the top of the base 7 will be inserted into the rectangular opening slots on the connecting sleeves 4 at the bottom of the main support plate 1, thereby providing stable support for the main support plate 1 and preventing it from moving in the horizontal direction. When the main support plate 1 is installed on the upper part, the top of the support column 3 on the lower main support plate 1 will be inserted into the rectangular opening slots on the connecting sleeves 4 at the bottom of the upper main support plate 1, thereby providing stable support for the upper main support plate 1.

[0019] In this embodiment, as Figure 1 , Figure 2 and Figure 4As shown, the top of the main support plate 1 is provided with two circular opening slots, and the display tray 2 is located directly below the two circular opening slots on the top of the main support plate 1. After assembly, the items to be displayed can be placed on the top of the display tray 2 through the circular opening slots on the top of the main support plate 1. When the stepper motor 8 rotates, it will drive the items on the top of the display tray 2 to rotate and be displayed in the circular opening slots on the top of the main support plate 1, thereby achieving a visual communication effect.

[0020] In this embodiment, as Figure 2 , Figure 3 and Figure 5 As shown, each drive block 5 has a hexagonal block at its bottom end, and the top of the drive shaft 6 and the top of the main shaft of the stepper motor 8 each have a corresponding hexagonal slot. During assembly, the hexagonal block at the bottom of the drive block 5 can be embedded in the hexagonal slots at the top of the drive shaft 6 and the top of the main shaft of the stepper motor 8. Therefore, when the stepper motor 8 rotates, it can drive all drive blocks 5 and their outer gears to rotate synchronously through the cooperation of drive blocks 5 and drive shaft 6.

[0021] In this embodiment, as Figure 4 and Figure 5 As shown, each drive block 5 has a gear on its outer side, and the display tray 2 also has a corresponding tooth groove on its outer side. The gear on the outer side of the drive block 5 meshes with the tooth groove on the outer side of the display tray 2. When the stepper motor 8 rotates, it will drive all drive blocks 5 and their outer gears to rotate synchronously through the drive block 5 and the drive shaft 6. When the gear on the outer side of the drive block 5 rotates, it will mesh with the tooth groove on the outer side of the display tray 2 to drive the display tray 2 to rotate slowly. This allows the items on the top of the display tray 2 to rotate and be displayed in the circular opening slot on the top of the main support plate 1, thereby achieving a visual communication effect.

[0022] In this embodiment, as Figures 1-3 and Figure 6 As shown, the support column 3 can rotate on top of the main support plate 1. When the support column 3 is rotated to a vertical position, it can also slide up and down. When the support column 3 slides down to the bottom, its bottom end can be inserted into the rectangular grooves on both sides of the top of the main support plate 1 and fit tightly against the inner wall of the rectangular groove. During assembly, the support column 3 on top of the first main support plate 1 can be rotated to a vertical position and the support column 3 can be pushed down. At this time, the bottom end of the support column 3 will be inserted into the rectangular grooves on both sides of the top of the main support plate 1, so the support column 3 cannot rotate, thus locking the support column 3 in a vertical position. When the bracket needs to be folded up after use, the main support plates 1 can be lifted up one by one to separate them, and then the support column 3 can be pulled up to the top to rotate to a horizontal position and fold up, saving the space occupied during storage.

[0023] Example 2, based on Example 1, such as Figures 1-6As shown, the bottom outer wall of the drive shaft 6 is provided with two vertical protrusions, and the top of the drive block 5 is provided with a groove corresponding to the size of the bottom of the drive shaft 6. During assembly, the bottom part of the drive shaft 6 can be inserted into the groove on the top of the drive block 5, thereby fixing the drive shaft 6 to the top of the drive block 5. Moreover, the vertical protrusions on the bottom outer wall of the drive shaft 6 cooperate with the drive block 5 to ensure that the two rotate synchronously.

[0024] The working principle of this embodiment is as follows: When using this bracket to display items, first place the base 7 stably on the ground or table, and connect the stepper motor 8 to the external controller and power supply. Then, take a main support plate 1 and install it on top of the base 7. During installation, the vertical rods on both sides of the top of the base 7 will insert into the rectangular opening slots on the bottom connecting sleeve 4 of the main support plate 1, thereby stably supporting the main support plate 1 and preventing it from moving horizontally. At the same time, the hexagonal block at the bottom of the drive block 5 will embed into the hexagonal slot at the top of the main shaft of the stepper motor 8, thus enabling the stepper motor 8 to be connected to the drive block 5. If further installation is needed on top... To display more items on the main support plate 1, the support column 3 at the top of the first main support plate 1 can be rotated to a vertical position and pushed downwards. The bottom end of the support column 3 will then insert into the rectangular slots on both sides of the top of the main support plate 1, preventing it from rotating and locking it in a vertical position. Next, a drive shaft 6 is taken and its bottom end is inserted into the groove at the top of the drive block 5, thus fixing the drive shaft 6 to the top of the drive block 5. The vertical protrusion on the outer wall of the bottom end of the drive shaft 6 cooperates with the drive block 5 to ensure synchronous rotation. Then, a new main support plate 1 is installed on the first main support plate. During installation, the top of the support column 3 on the lower main support plate 1 is inserted into the rectangular slot on the bottom connecting sleeve 4 of the upper main support plate 1, thus providing stable support for the upper main support plate 1. Simultaneously, the hexagonal block at the bottom of the drive block 5 on the inner side of the upper main support plate 1 is embedded into the hexagonal slot at the top of the drive shaft 6 on the lower main support plate 1, allowing the drive block 5 to be fully connected to the stepper motor 8. The main support plate 1 can then be installed in the same manner. After assembly, the items to be displayed can be placed on top of the display tray 2 through the circular slot at the top of the main support plate 1. Then, the stepper motor is activated via an external controller. When stepper motor 8 is turned on, it will drive all drive blocks 5 and their outer gears to rotate synchronously through drive block 5 and drive shaft 6. When the gears on the outer side of drive block 5 rotate, they will cooperate with the tooth grooves on the outer side of display tray 2 to drive display tray 2 to rotate slowly. This allows the items on the top of display tray 2 to rotate and be displayed in the circular opening slot on the top of main support plate 1, thus achieving a visual communication effect. When the bracket needs to be folded up after use, the main support plate 1 can be lifted up one by one to separate them. Then, the support column 3 can be pulled up to the top to rotate to a horizontal position and fold up. Finally, the drive shaft 6 can be removed from the top of drive block 5 and stored separately.

[0025] The following points should be noted in this article: 1. The accompanying drawings of this embodiment only involve the structures involved in this embodiment; other structures can refer to the general design.

[0026] 2. Where there is no conflict, this embodiment and the features in the embodiment can be combined with each other to obtain new embodiments.
