Technical Field

[0001] The utility model relates to the technical field of projection, in particular to a dustproof and height-adjustable projector. Background Art

[0002] A projector is an optical instrument that uses optical elements to magnify the outline of a workpiece and project it onto a screen. It can use transmitted light for contour measurement and reflected light to measure the surface shape of blind holes and observe the surface of parts. Projectors are particularly suitable for measuring complex contours and small workpieces, such as watch parts, stamping parts, electronic components, templates, molds, threads, gears, and forming tools. They have high inspection efficiency and are easy to use.

The upper end of the top plate 1 is fixedly connected to a self-locking motor 3. The output shaft end of the self-locking motor 3 is fixedly connected to a rotating cylinder 19. The rotating cylinder 19 is rotatably connected to the lower end of the top plate 1. The interior of the rotating cylinder 19 is slidably connected to a rotating rod 20. The rotating rod 20 is fixedly installed on the top of the projector body 6. A first sliding groove 21 is provided inside the rotating cylinder 19. Two first sliding blocks 22 are slidably connected inside the first sliding groove 21. The two first sliding blocks 22 are fixedly connected to the rotating rod 20. A height adjustment member is installed between the top plate 1 and the projector body 6, and the height adjustment member is used to adjust the height of the projector body 6. A plurality of heat dissipation holes 18 are provided on the left and right end surfaces of the projector body 6. Dustproof parts are installed on the left and right ends of the projector body 6, and the dustproof parts are used to protect the heat dissipation holes 18. During operation, the present invention can adjust the angle of the projector body 6 between 0-90 degrees. This method of adjusting the angle of the projector body 6 is simple and convenient, so that customers can adjust the angle of the projector body 6 in a timely manner according to specific usage conditions, making it more convenient to use.

[0027] Furthermore, the upper end of the top plate 1 is fixedly connected with a plurality of fixing plates 2, and the upper end surfaces of the plurality of fixing plates 2 are provided with mounting holes 4. During operation, the presence of the plurality of fixing plates 2 and the mounting holes 4 facilitates the fixing and installation of the top plate 1 in a suitable position indoors.

[0028] Furthermore, the dustproof component includes a support frame 15 and a dustproof screen 16. The support frames 15 are fixedly connected to the left and right ends of the projector body 6. The dustproof screens 16 are slidably connected to the interiors of the two support frames 15. The two dustproof screens 16 are tightly fitted to the projector body 6 and are respectively located at the left and right ends of the heat dissipation holes 18 on the left and right sides of the projector body 6. During operation, the dustproof screens 16 can block both sides of the two sets of heat dissipation holes 18 and protect the heat dissipation holes 18, preventing external dust from entering the projector body 6 through the heat dissipation holes 18 and affecting the normal operation of the projector body 6.

[0029] Furthermore, the upper ends of the two dust screens 16 are fixedly connected with convex plates 17, and the end faces of the convex plates 17 are all in an inverted L-shape. When working, the presence of the convex plates 17 makes it convenient for the operator to hold the convex plates 17 and take and put the dust screens 16.

[0030] Furthermore, the height adjustment member includes an electric telescopic rod 12, a connecting plate 14, a second sliding rod 13, a second annular guide rail 10, and a second sliding hole 11. The upper end of the projector body 6 is fixedly connected to the second annular guide rail 10. The circumferential surface of the second annular guide rail 10 defines two second sliding holes 11. The interiors of the two second sliding holes 11 are slidably connected to the second sliding rods 13. The top ends of the two second sliding rods 13 are fixedly connected to the connecting plate 14. The bottom end of the top plate 1 is fixedly connected to the two electric telescopic rods 12, and the output ends of the two electric telescopic rods 12 are respectively fixedly connected to the two connecting plates 14. During operation, the two electric telescopic rods 12 are externally connected to the same control terminal, which is used to simultaneously control the operation of the two electric telescopic rods 12. When the electric telescopic rods 12 are in operation, they will drive the projector body 6 to move up and down with the cooperation of the connecting plate 14, the second sliding rod, and the second annular guide rail 10, thereby adjusting the height of the projector body 6.

[0031] Furthermore, a first annular guide rail 5 is fixedly connected to the bottom end of the top plate 1. Two first sliding holes 7 are defined in the circumferential surface of the first annular guide rail 5. First sliding rods 8 are slidably connected to the interiors of the two first sliding holes 7.

The two first sliding rods 8 extend downward into the two fixed cylinders 9 and are slidably connected to the two fixed cylinders 9. During operation, when the angle of the projector body 6 is adjusted, the two first sliding rods are driven to rotate along the two first sliding holes 7 in cooperation with the fixed cylinders 9. Therefore, with the mutual cooperation of the first annular guide rail 5, the first sliding holes 7, the first sliding rods 8, and the fixed cylinders 9, the angle of the projector body 6 can be adjusted more smoothly.

[0032] Furthermore, two second sliding grooves 23 are defined within each of the two fixed cylinders 9. Two second sliding blocks 24 are slidably connected within each of the two second sliding grooves 23. The two second sliding blocks 24 are fixedly connected to the first sliding rod 8, and the second sliding blocks 24 and the first sliding rod 8 form an integral structure. During operation, the interaction between the second sliding grooves 23 and the second sliding blocks 24 not only allows the first sliding rod 8 to stably rotate along the first sliding hole 7, but also allows the first sliding rod 8 to stably move within the fixed cylinder 9, and the first sliding rod 8 is not easily separated from the fixed cylinder 9.

[0033] Furthermore, the first annular guide rail 5 is located above the second annular guide rail 10, the extended central axis of the first annular guide rail 5 coincides with the central axis of the second guide rail, and the two second sliding holes 11 are located below the two first sliding holes 7. During operation, the height of the projector body can be adjusted while also adjusting the angle of the projector body, and the height adjustment and angle adjustment do not conflict with each other.

[0034] Working principle:

[0035] During use, the top plate 1 can be stably installed in a suitable position in the room through the cooperation of the mounting hole 4 and the fixing plate 2. Then the customer can control the self-locking motor 3 or the height adjustment part according to his own needs, and adjust the angle and height of the projector body 6 from 0 to 90 degrees respectively until the projector body is at a suitable height and angle. This is more convenient for customers to use and can enable customers to have a better viewing experience.
