Description

Technical Field

[0001] This utility model relates to the technical field of projector equipment, specifically an interactive design display projector. Background Technology

[0002] With the continuous development of projection technology, projectors have been widely used in various fields such as education, office work, and home entertainment. In actual use, users often need to adjust the projection angle of the projector according to different usage scenarios and projection needs to obtain a clear and suitable projected image.

[0003] Most projectors on the market currently have limitations in their angle adjustment mechanisms. Some projectors use simple stand supports, requiring manual loosening of screws to adjust the angle, followed by tightening, which is cumbersome and makes precise angle positioning difficult. Other projectors have a limited angle adjustment range, failing to meet the needs of large tilt and drop projections, especially in suspended installations or special placement scenarios where the limitations of angle adjustment are more pronounced.

[0004] Therefore, those skilled in the art have provided an interactive design display projector to address the problems raised. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides an interactive design display projector.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] An interactive design display projector, comprising:

[0008] Projector body;

[0009] Multiple limiting blocks are elastically arranged on both sides of the projector body, and the multiple limiting blocks are arranged in a ring at equal intervals. The side of the limiting block away from the projector body is set as an inclined surface, and one side of the inclined surface is flush with the side of the projector body. A limiting area is formed between two adjacent limiting blocks.

[0010] The bracket is rotatably mounted on both sides of the projector body, and the rotation point is located at the center of the plurality of limiting blocks;

[0011] The limiting groove is located symmetrically opened on the U-shaped frame, and the limiting groove is located on the rotation path of the limiting block;

[0012] When the projector body remains stable, the bottom of the inclined surface of the limiting block elastically presses against the limiting groove or the top edge of the U-shaped frame.

[0013] Preferably, the limiting block is configured to have a fan-shaped projection on the side of the projector body, and the two side edges of the limiting block are adapted to the two side edges of the limiting groove.

[0014] Preferably, the rotation point of the projector body is located at the center of the side of the projector body, and the distance from the rotation point to both ends of the projector body is less than the distance from the rotation point to the horizontal part of the bracket.

[0015] Preferably, the projector body has multiple clearance slots on both sides, the limiting block is movably inserted into the clearance slots, and a spring is also provided in the clearance slots.

[0016] Preferably, the horizontal portion of the frame has multiple mounting holes, and the multiple mounting holes are arranged in a rectangular pattern.

[0017] In summary, this utility model has the following beneficial technical effects:

[0018] The bottom of the inclined surface of the limiting block elastically presses against the edges of the limiting groove on both sides or the top edges of the two sides of the U-shaped frame. The pressing force can generate static friction, which counteracts the rotational tendency caused by the weight of the projector itself. Depending on the distance the limiting block extends out of the side of the projector body, a wide range of angle adjustments can be achieved. Attached Figure Description

[0024] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0025] An interactive design display projector, with reference to Figure 1-3 ,include:

[0026] The projector body 1, as the core load-bearing component of the projector, integrates key modules such as optical imaging and circuit control. Its side needs to provide an installation foundation for the support structure to ensure the stability and functionality of the overall device.

[0027] Multiple limiting blocks 11 are elastically arranged on both sides of the projector body 1. Furthermore, multiple clearance slots 12 are formed on both sides of the projector body 1. The limiting blocks 11 are movably inserted into the clearance slots 12, and springs 13 are also installed within the clearance slots 12. The clearance slots 12 provide movement space for the limiting blocks 11, allowing them to retract inwards when compressed, cooperating with the elastic restoring action of the springs 13. The multiple limiting blocks 11 are arranged in an evenly spaced ring. This ring arrangement design ensures that the projector body 1 can form a stable limiting position with the subsequent U-shaped frame 2 at different rotation angles, avoiding the adjustment limitations caused by single-angle limiting. The side of the limiting block 11 away from the projector body 1 is set as an inclined surface with an angle less than 45 degrees. This increases the frictional force generated by contact with the inclined surface and facilitates the adjustment of the limiting block 11 position by compression along the inclined surface. One side of the inclined surface is flush with the side of the projector body 1, and a limiting area is formed between two adjacent limiting blocks 11.

[0028] The U-shaped bracket 2 is rotatably mounted on both sides of the projector body 1, with the rotation point located at the center of multiple limiting blocks 11. All limiting blocks 11 are equidistant from the rotation point to avoid the problem that some limiting blocks 11 cannot cooperate with the limiting groove 21 due to distance differences, thus ensuring the uniformity of the limiting function during adjustment.

[0029] The inclined design of the limiting block 11 allows it to easily contact and press against the U-shaped frame 2 before entering the side of the projector body 1, facilitating the rotation of the projector body 1. The weight of the projector body 1 itself is insufficient to allow the U-shaped frame 2 to enter the side of the projector body 1.

[0030] The limiting groove 21 is symmetrically located on the U-shaped frame 2. This symmetrical arrangement ensures that the force on both sides of the U-shaped frame 2 is balanced, avoiding deformation caused by force on one side. The limiting groove 21 is located on the rotation path of the limiting block 11 and is the key to their cooperation. When the projector body 1 rotates, the limiting block 11 will enter or disengage from the limiting groove 21 along the rotation path. The angle is fixed by the engagement of the groove and the block. Compared with simply relying on edge compression, the limiting groove 21 can provide more precise angle adjustment, allowing users to quickly locate the commonly used angle according to their needs and improve adjustment efficiency.

[0031] When the projector body 1 remains stable, the bottom of the inclined surface of the limiting block 11 elastically presses against one edge of the limiting groove 21 or the top edge of one side of the U-shaped frame 2. Specifically, the pressing force generates static friction, counteracting the rotational tendency caused by the projector's own weight. Even under slight vibration, it can maintain angular stability and prevent the projected image from shifting. Simultaneously, the dual action of "pressing against both edges of the limiting groove 21 or the top edges of both sides of the U-shaped frame 2" further expands the stable angle range. Depending on the distance the limiting block 11 extends beyond the side of the projector body 1, a wide range of angle adjustments can be achieved. Furthermore, the overall structure can be placed or suspended, both allowing for large tilt and slant adjustments, making it suitable for various applications. When the U-shaped frame 2 contacts the limiting block 11 at the top of the inclined surface, it cannot rotate in that direction, allowing for use at specific angles.

[0032] The limiting block 11 is set to be a fan-shaped projection on the side of the projector body 1. The two sides of the limiting block 11 are adapted to the two sides of the limiting groove 21, which can maximize the use of the gap between adjacent limiting blocks 11 and make the adjustment range larger.

[0033] The rotation point of the projector body 1 is located at the center of its side, which allows the center of gravity of the projector body 1 to be located between the two rotation points, thus increasing stability after adjustment. This also improves the balance at both ends of the projector body 1 when it rotates around this point, reducing the center of gravity shift during rotation.

[0034] The distance from the rotation point to both ends of the projector body 1 is less than the distance from the rotation point to the horizontal part of the U-shaped frame 2, which can increase the rotation range of the projector body 1 and allow the projector to achieve a greater range of tilt angle adjustment to meet the needs of different projection scenarios.

[0035] The horizontal part of the frame 2 has multiple mounting holes 22, which are arranged in a rectangular pattern. The rectangular mounting holes 22 provide multiple fixing options for the frame 2: users can choose different mounting holes 22 for fixing according to the usage scenario (such as desktop placement, wall mounting, tripod connection), without the need for additional brackets, thus improving the versatility of the structure.

[0036] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
