Description

Technical Field

[0001] This utility model relates to the field of projector technology, and in particular to a geometric projection device. Background Technology

[0002] Projectors are a prime example of modern geometric projection principles. They project digital images onto a screen as a cone-shaped beam of light through a lens, perfectly achieving central projection in geometry and producing a visually immersive experience. To ensure this stability and accuracy, projectors require a stand. A stand increases the projector's stability, preventing blurring and jitter caused by device movement, and reducing reliance on digital correction functions that sacrifice image quality. In short, a stand is the physical foundation that ensures the projector continuously performs its geometric projection function from the correct position and angle.

[0003] In existing technologies, traditional projector stands are usually designed for fixed-point installation, and their functions are mainly limited to simple height adjustment, which cannot adjust the horizontal position. Once installed, the projection range is strictly limited, making it difficult to flexibly adapt to different usage scenarios. Traditional projector stands have limited functions, and in complex ambient light, stray light can easily interfere with the projected image. In addition, when not in use, the projector lens is directly exposed to the air and is easily scratched by accident. Therefore, we propose a geometric projection device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a geometric projection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A geometric projection device includes a mounting plate. A projector body is fixedly connected to the bottom of the mounting plate. Two T-shaped columns are fixedly connected to the top of the mounting plate. Strip plates are slidably fitted onto the outer walls of the two T-shaped columns. Silicone baffles are fixedly connected to the outer walls of the two strip plates. A vertical rod is fixedly connected to the top of the mounting plate. A vertical sleeve is slidably fitted onto the outer wall of the vertical rod. A threaded hole is formed on the outer wall of the vertical sleeve. A hand-tightening bolt is threaded onto the inner wall of the threaded hole. An arc-shaped extrusion plate is rotatably embedded at one end of the hand-tightening bolt. Multiple annular grooves are evenly formed on the outer wall of the vertical rod. Rubber sheets are fixedly connected to both the arc-shaped extrusion plate and the outer wall of the T-shaped columns. A movable component is provided at the top of the vertical sleeve.

[0007] Preferably, the moving component includes a U-shaped component, the top of the vertical sleeve is fixedly connected to the bottom of the U-shaped component, an I-shaped component is slidably connected to the inner wall of the U-shaped component, and two T-shaped shafts are rotatably embedded in the outer wall of the U-shaped component. A pulley is fixedly sleeved on one end of each of the two T-shaped shafts, and the pulley reduces the resistance when the U-shaped component moves.

[0008] Preferably, the outer walls of both strip plates are provided with strip grooves, and the inner walls of the two strip grooves are slidably connected to the outer walls of the two T-shaped columns respectively. The strip grooves cooperate with the T-shaped columns to assist the strip plates in rotating.

[0009] Preferably, the arc-shaped extrusion plate is located inside one of the annular grooves, and the arc-shaped extrusion plate is embedded in the annular groove of the vertical rod, using a rubber sheet to increase friction and thus fix the vertical rod.

[0010] Preferably, a sliding column is fixedly connected to the top of the vertical rod.

[0011] Preferably, the outer walls of both pulleys are slidably connected to the outer wall of the I-shaped part, and both ends of the I-shaped part are fixedly connected to wall fasteners, so that the I-shaped part is fixed to the wall by the wall fasteners at both ends.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] This solution allows for convenient adjustment of the projector's height and horizontal angle by using a vertical rod that rotates horizontally and moves vertically around a vertical sleeve, along with a fixing structure consisting of hand-tightened bolts, an arc-shaped extrusion plate, and an annular groove. Simultaneously, the T-shaped shaft on the U-shaped component drives the pulley to roll along the I-shaped component, and combined with the stable installation of the I-shaped component through the wall-mounted fasteners, further enables the horizontal movement of the entire device, flexibly adapting to the projection position requirements of different usage scenarios.

[0014] The position of the silicone baffle can be adjusted as needed by sliding the T-shaped column and the strip plate on the top of the mounting plate to reduce light interference with the projected image. At the same time, when not in use, the silicone baffle can be placed over the lens of the projector to provide physical protection for the lens. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Depend on Figures 1-4 As shown, a geometric projection device is disclosed, including a mounting plate 1. A projector body 2 (W1070) is fixedly connected to the bottom of the mounting plate 1, and two T-shaped columns 3 are fixedly connected to the top of the mounting plate 1. Strip plates 4 are slidably fitted on the outer walls of the two T-shaped columns 3. Strip grooves are formed on the outer walls of the two strip plates 4. The inner walls of the two strip grooves are slidably connected to the outer walls of the two T-shaped columns 3 respectively. The T-shaped structure of the T-shaped column 3 and the strip groove of the strip plate 4 are slidably engaged, which can guide the sliding of the strip plate 4 and prevent the strip plate 4 from detaching. At the same time, the rubber sheet on the outer wall of the T-shaped column 3 can increase the friction with the strip plate 4.

[0023] Both strip plates 4 have silicone shields 5 fixedly connected to their outer walls. The silicone shields 5 move with the strip plates 4 to the appropriate position to block stray light and improve the quality of the projected image. When not in use, they can be moved to the lens of the projector body 2 to protect the lens using the softness of the silicone material and prevent the lens from being scratched.

[0024] A vertical rod 6 is fixedly connected to the top of the mounting plate 1. A vertical sleeve 10 is slidably fitted on the outer wall of the vertical rod 6. The vertical rod 6 and the vertical sleeve 10 are slidably engaged, providing a support base for the projector body 2 to move up and down and rotate horizontally.

[0025] The outer wall of the vertical sleeve 10 is provided with a threaded hole, and the inner wall of the threaded hole is threaded with a hand-tightening bolt 7. One end of the hand-tightening bolt 7 is rotatably embedded with an arc-shaped extrusion plate 8. The outer wall of the vertical rod 6 is evenly provided with multiple annular grooves 9. The arc-shaped extrusion plate 8 is located inside one of the annular grooves 9. The multiple annular grooves 9 provide multiple fixing points for the arc-shaped extrusion plate 8, so that the vertical rod 6 can be fixed at different height positions, realizing multi-level adjustment of the height of the projector body 2. The arc-shaped extrusion plate 8 and the outer wall of the T-shaped column 3 are both fixedly connected with rubber sheets. The top of the vertical rod 6 is fixedly connected with a sliding column 11.

[0026] The top of the vertical sleeve 10 is provided with a moving component, which includes a return member 12. The return member 12 provides guidance and support for the horizontal movement of the entire device, and also serves as a structure connecting the vertical sleeve 10 and the pulley 15 to realize the transmission of force.

[0027] The top of the vertical sleeve 10 is fixedly connected to the bottom of the spiral-shaped part 12. The inner wall of the spiral-shaped part 12 is slidably connected to the I-shaped part 13. The outer wall of the spiral-shaped part 12 is rotatably embedded with two T-shaped shafts 14. One end of each of the two T-shaped shafts 14 is fixedly fitted with a pulley 15. The outer walls of the two pulleys 15 are slidably connected to the outer wall of the I-shaped part 13. The T-shaped shafts 14 not only fix the pulleys 15, but also ensure that the pulleys 15 rotate flexibly, reducing the resistance when the pulleys 15 roll.

[0028] Both ends of the I-shaped part 13 are fixedly connected to wall fasteners 16. The wall fasteners 16 can firmly install the I-shaped part 13 on the wall. The wall fasteners 16 are fixed to the existing expansion bolts through multiple strip holes opened on the outer wall.

[0029] Working principle: When in use, the two T-shaped columns 3 on the top of the mounting plate 1 slide in conjunction with the strip plate 4. The strip plate 4 can slide along the T-shaped columns 3 to adjust the position of the silicone baffle 5. When in use, it serves to block stray light, and when not in use, the silicone baffle 5 is placed on the lens of the projector body 2 to provide protection.

[0030] The vertical rod 6 can rotate horizontally and move up and down around the vertical sleeve 10. When the vertical rod 6 is fixed, the hand-tightening bolt 7 is tightened to make the arc-shaped extrusion plate 8 embedded in the annular groove 9 of the vertical rod 6. The rubber sheet is used to increase the friction to fix the vertical rod 6, while the sliding column 11 can prevent the vertical sleeve 10 from detaching from the vertical rod 6.

[0031] The two T-shaped shafts 14 on the U-shaped part 12 drive the two pulleys 15 to roll along the I-shaped part 13, which facilitates the horizontal movement of the whole device. The I-shaped part 13 is fixed to the wall by the wall fixing parts 16 at both ends, thereby realizing the flexible adjustment and stable installation of the projector body 2 in height and horizontal position.
