Description

Technical Field

[0001] This utility model relates to the field of display board technology, and in particular to a portable display board. Background Technology

[0002] Display boards are visual media used to intuitively convey information, guide behavior, or display content. They are commonly found in various public settings. In traditional technology, display boards often use a fixed structure, such as a metal or plastic bracket to support an advertising panel. However, while using a fixed support frame to support the advertising panel can meet the long-term display needs of some fixed locations, fixed display boards take up a lot of space when it is necessary to adjust the display angle to adapt to different lighting or viewing angles, or when they need to be carried and transported during non-use periods. This reduces the number of display boards that can be carried and transported, resulting in the technical problem of poor carrying and transport efficiency for fixed display boards. Utility Model Content

[0003] Therefore, it is necessary to provide a portable display board to address the technical problem of poor carrying and transportation efficiency of fixed display boards.

[0004] A portable display board includes: a support frame, an advertising board, a rotating rod, an elastic element, and a limiting component. There are two support frames, two advertising boards, two elastic elements, and two limiting components. One end of each support frame is rotatably mounted on the rotating rod, and they move closer to or further away from each other around the rotating rod. One support frame has multiple limiting grooves at its end facing away from the other support frame. Each limiting groove is arranged around the rotation axis of the rotating rod. Each advertising board is mounted on its respective support frame. Each limiting component is located at both ends of the rotating rod, and each limiting component is used to insert into or separate from one of the limiting grooves of an adjacent support frame. Each elastic element provides elastic force for the limiting component to insert into the limiting groove.

[0005] In one embodiment, the support frame includes a rotating part and a mounting part. The rotating part is provided with a rotating hole that is rotatably connected to the rotating rod. One end of the rotating part is provided with the limiting groove, and the other end of the rotating part is provided with a clearance position for accommodating the rotating part of another support frame.

[0006] In one embodiment, the rotating part is further provided with a receiving groove that communicates with the limiting groove, and the receiving groove communicates with the rotating hole.

[0007] In one embodiment, the mounting part is provided with a mounting slot and a display space communicating with the mounting slot, and the advertising board is inserted into the mounting slot.

[0008] In one embodiment, the rotating rod includes a shaft and a guide portion, the shaft being rotatably connected to the support frame, and the guide portion being slidably connected to the limiting component.

[0009] In one embodiment, the guide portion has a D-shaped cross-section.

[0010] In one embodiment, the limiting component includes an adjusting member and a blocking member. The adjusting member is slidably connected to the rotating rod, and the blocking member is mounted on the rotating rod and abuts against the elastic member. The elastic member abuts against the adjusting member to provide elastic force for the adjusting member to insert into the limiting groove.

[0011] In one embodiment, the adjusting member includes a slider, a limiting block, and a lever. The slider has a sliding hole that is slidably connected to the rotating rod. The limiting block is connected to the outer wall of the slider and is inserted into the limiting groove. The lever is connected to the end of the limiting block that is away from the support frame.

[0012] In one embodiment, the slider is further provided with a receiving groove communicating with the sliding hole, and the elastic element is disposed in the receiving groove.

[0013] In one embodiment, the blocking member includes a connecting portion and a blocking portion, the connecting portion being connected to the rotating rod, and the blocking portion abutting against the elastic member.

[0014] The portable display board provided in this application has the following advantages: by rotatably mounting two support frames on a rotating rod, and setting multiple limiting slots around the rotation axis on one of the support frames, and using a limiting component provided with elastic force by an elastic element, the user can selectively insert or disengage the limiting component into the limiting slot, thereby achieving rapid and multi-level adjustment of the angle between the two support frames. After adjustment, the limiting component automatically inserts into the corresponding limiting slot under the action of the elastic element, achieving stable locking and preventing accidental rotation of the support frame during the display process, thus ensuring the stability of the display effect. By rotating and folding the two support frames in the same direction, the overall volume can be significantly reduced, thereby improving the carrying and transportation efficiency of the display board.

[0023] like Figure 1 and Figure 5 As shown, it is the portable display board 100 of this utility model.

[0024] like Figures 1 to 2As shown, the portable display board 100 includes: a support frame 10, an advertising board 20, a rotating rod 30, an elastic element 40, and a limiting component 50. There are two support frames 10, two advertising boards 20, two elastic elements 40, and two limiting components 50. One end of each support frame 10 is rotatably mounted on the rotating rod 30, and they move closer to or further apart from each other around the rotating rod 30. One support frame 10 has multiple limiting grooves 112 at its end facing away from the other support frame 10. Each limiting groove 112 is arranged around the rotation axis of the rotating rod 30. Each advertising board 20 is mounted on its respective support frame 10. Each limiting component 50 is located at both ends of the rotating rod 30, and each limiting component 50 is used to insert into or separate from one of the limiting grooves 112 of an adjacent support frame 10. Each elastic element 40 provides support for the limiting component 50. The elastic force of the insertion limit slot 112 is achieved by rotating two support frames 10 onto the rotating rod 30, and setting multiple limit slots 112 around the rotation axis on one of the support frames 10. With the help of the limit component 50 provided by the elastic element 40, the user can selectively insert into or disengage from the limit slot 112 by operating the limit component 50, thereby realizing the rapid and multi-level adjustment of the angle between the two support frames 10. After the adjustment is in place, the limit component 50 automatically inserts into the corresponding limit slot 112 under the action of the elastic element 40, achieving stable locking and preventing the support frame 10 from rotating accidentally during the display process, thus ensuring the stability of the display effect. By rotating and folding the two support frames 10 in the same direction, the overall volume can be significantly reduced, thereby improving the carrying and transportation efficiency of the display board.

[0025] The following text, combined with Figures 1 to 5 Further explanation is provided regarding the aforementioned portable display board 100.

[0026] To reduce the overall size of the display board, such as Figures 2 to 3 As shown, the support frame 10 includes a rotating part 11 and a mounting part 12. The rotating part 11 is provided with a rotating hole 111 that is rotatably connected to the rotating rod 30. One end of the rotating part 11 is provided with a limiting groove 112, and the other end of the rotating part 11 is provided with a clearance position 113 for accommodating the rotating part 11 of another support frame 10. By providing a clearance position 113 for accommodating the rotating part 11 of another support frame 10 in the rotating part 11, the rotating parts 11 of the two support frames 10 can be nested in each other, thereby further reducing the axial thickness of the two support frames 10 along the rotating rod 30, reducing the space occupied by the display board, and achieving the purpose of reducing the overall volume of the display board.

[0027] To reduce the axial space occupied by the limiting assembly 50 along the rotating rod 30, such as Figure 3As shown, the rotating part 11 is also provided with a receiving groove 114 that connects to the limiting groove 112. The receiving groove 114 is connected to the rotating hole 111. The receiving groove 114 is used to accommodate part of the limiting component 50, thereby effectively reducing the space occupied by the limiting component 50 along the axial direction of the rotating rod 30.

[0028] To reduce the cost of using the portable display board 100, such as Figure 3 As shown, the installation part 12 is provided with an installation slot 121 and a display space 122 that connects to the installation slot 121. The advertising board 20 is plugged into the installation slot 121. The advertising board 20 is installed in the installation slot 121 of the installation part 12 by plugging in, which can effectively increase the convenience of installation and replacement of the advertising board 20 and reduce the cost of using the portable display board 100.

[0029] To ensure the reliability of the angle adjustment and locking of the limit component 50, such as Figure 2 As shown, the rotating rod 30 includes a shaft 31 and a guide 32. The shaft 31 is rotatably connected to the support frame 10, and the guide 32 is slidably connected to the limiting component 50. The guide 32 has a D-shaped cross-section, which can effectively prevent the limiting component 50 from rotating circumferentially relative to the rotating rod 30 during sliding. This ensures that the limiting component 50 can effectively prevent the support frame 10 from rotating circumferentially relative to the rotating rod 30, thereby ensuring the reliability of the angle adjustment and locking of the limiting component 50.

[0030] To achieve the automatic reset and locking function of the limit component 50, such as Figure 2 As shown, the limiting component 50 includes an adjusting member 51 and a blocking member 52. The adjusting member 51 is slidably connected to the rotating rod 30. The blocking member 52 is installed on the rotating rod 30 and abuts against the elastic member 40. The elastic member 40 abuts against the adjusting member 51 to provide elastic force for the adjusting member 51 to insert into the limiting groove 112. The adjusting member 51 is used to perform the action of inserting / disengaging from the limiting groove 112. The blocking member 52 is fixed on the rotating rod 30 and abuts against one end of the elastic member 40. By compressing the elastic member 40 between the adjusting member 51 and the blocking member 52, a continuous elastic force is provided to the adjusting member 51 in the direction of the limiting groove 112, so as to realize the automatic reset and locking function of the limiting component 50.

[0031] Specifically, such as Figure 4As shown, the adjusting component 51 includes a slider 511, a limiting block 512, and a lever 513. The slider 511 has a sliding hole 514 that is slidably connected to the rotating rod 30. The limiting block 512 is connected to the outer wall of the slider 511 and is inserted into the limiting groove 112. The lever 513 is connected to the end of the limiting block 512 away from the support frame 10. The slider 511 slides with the rotating rod 30 through the sliding hole 514 to ensure smooth movement. The limiting block 512 is directly responsible for the insertion and separation of the limiting groove 112 to achieve locking and unlocking. The lever 513 is located at the end of the limiting block 512, providing a convenient operating force point for the user, allowing the user to easily overcome elastic force to pull the adjusting component 51 and achieve angle adjustment.

[0032] To ensure the stability of the elastic element 40 in use, such as Figure 4 As shown, the slider 511 is also provided with a receiving groove 515 that connects to the sliding hole 514. The elastic element 40 is disposed in the receiving groove 515. The elastic element 40 is housed inside the slider 511, which helps to reduce the overall axial dimension of the limiting component 50 and make the structure more compact. At the same time, the receiving groove 515 also plays a role in positioning and protecting the elastic element 40, preventing the elastic element 40 from falling off the rotating rod 30, and achieving the purpose of ensuring the stability of the elastic element 40 in use.

[0033] To effectively prevent the adjusting element 51 from disengaging from the rotating rod 30, such as Figure 2 As shown, the blocking member 52 includes a connecting part 521 and a blocking part 522. The connecting part 521 is connected to the rotating rod 30, and the blocking part 522 abuts against the elastic member 40. The blocking member 52 is a bolt. The connecting part 521 is used to achieve a fixed connection with the rotating rod 30 through threads, and the blocking part 522 is used to provide a stable abutting surface with the end of the elastic member 40, so as to effectively prevent the adjusting member 51 from disengaging from the rotating rod 30.

[0034] like Figure 1 As shown, when the portable display board 100 provided in this application needs to be unfolded and its angle adjusted: the user pulls the levers 513 on both sides outwards by hand. The levers 513 drive the entire adjusting member 51 to slide outwards along the guide part 32 of the rotating rod 30 against the elastic force of the elastic member 40, so that the limiting block 512 exits from the current limiting groove 112. At this time, the two support frames 10 can rotate relative to each other around the rotating rod 30. When the desired display angle is reached, the levers 513 are released. Under the action of the elastic force of the elastic member 40, the adjusting member 51 slides inwards, and the limiting block 512 automatically inserts into the limiting groove 112 of the corresponding angle, thus completing the angle adjustment and locking.

[0035] like Figure 5As shown, when the portable display board 100 provided in this application needs to be folded and stored: operate the lever 513 in the above manner to disengage the limiting block 512 from the limiting groove 112, then rotate the two support frames 10 in the same direction until the mounting parts 12 of the two support frames 10 are approximately parallel and close together, release the lever 513, and under the elastic force of the elastic member 40, the adjusting member 51 slides inward, and the limiting block 512 automatically inserts into the limiting groove 112 at the corresponding angle, thus completing the folding and storage of the portable display board 100.

[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
