The laser is processed by an optical system through a reflector to project an image onto a screen or other surface. It features high brightness, high color saturation, and long lifespan, and is an upgraded replacement for traditional lamp projectors.
[0003] Traditional laser projectors rely on manual adjustment of the projector body for angle adjustment, which is cumbersome and the angle adjustment is limited and singular, requiring repeated adjustments. Furthermore, they cannot flexibly adapt to creative scenarios such as ceiling projection and projection on irregular surfaces, thus limiting their application scope.
[0004] In view of this, this utility model is proposed. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0030] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0031] Reference Figures 1-8 An integrally adjustable laser projector includes a connector 1 and a support rod 301 connected to the connector 1; a housing 4 is disposed at the end of the support rod 301 away from the connector 1, and the housing 4 is rotatably connected to the support rod 301; a reflector 5 is fixedly disposed on the housing 4; and a bracket 101 is also provided on the bottom outer wall of the connector 1.
[0032] In this utility model, the projector can be directly fixed and installed using the bracket 101. Before use, the angle of the support rod 301 within the connecting body 1 can be adjusted so that the support rod 301 can move the housing 4 and the reflector 5 as a whole. At this time, the reflector 5 can be adjusted in a larger direction. Then, the angle between the housing 4 and the support rod 301 can be adjusted, and the rotation of the housing 4 can drive the rotation of the reflector 5. This is a fine adjustment of the reflector 5, allowing for a smaller angle adjustment. Therefore, if needed in this application... If the adjustment angle is large, the position between the support rod 301 and the connecting body 1 can be adjusted first. After the large angle adjustment is completed, a small angle fine adjustment can also be made. Therefore, the reflector 5 can be precisely adjusted. The operation is convenient. After the large angle adjustment, fine adjustment can also be made. It can flexibly adapt to occasions such as ceiling projection and irregular surface projection. The application range is wide. At this time, the laser can be reflected by the reflector 5 on the projector of this application, thereby projecting the dynamic image onto any target surface, such as the wall, stage scenery, irregular object surface, etc.
[0033] Reference Figure 5 and Figure 6 The connecting body 1 is rotatably connected to the main shaft 3, the top of the support rod 301 is rotatably connected to the main shaft 3, and the bottom of the connecting body 1 is fixedly connected to the baffle 2, which has a long groove 201 for the support rod 301 to move.
[0034] Reference Figures 1-5 Two sector plates 202 are fixedly connected to the outer wall of the baffle 2. The sector plates 202 are provided with multiple first through holes 203, and the support rod 301 is provided with a second through hole 302. Insert rods 204 are inserted into the first through holes 203 and the second through holes 302.
[0035] In this application, when making large-angle adjustments, the support rod 301 can be moved manually so that the second through hole 302 on the support rod 301 corresponds to the position of the first through hole 203 on the sector plate 202. Then, the insertion rod 204 is inserted into the first through hole 203 and the second through hole 302 to fix the support rod 301. The main shaft 3 allows the support rod 301 to rotate easily. The bottom baffle 2 protects the internal components of the connecting body 1. The long groove 201 allows the support rod 301 to rotate easily for adjustment.
[0036] Reference Figure 6 and Figure 7The box body 4 has a rotating shaft 401 inside, and the bottom of the support rod 301 is fixedly connected to the rotating shaft 401. The box body 4 has a fixed motor 402 inside, and the output end of the motor 402 is connected to an output shaft 403. The output shaft 403 is equipped with a worm gear 404, and the rotating shaft 401 is equipped with a worm wheel 405 that meshes with the worm gear 404.
[0037] In this invention, the motor 402 can be connected to an external control device via a wire. The connection can be made using existing technology. The control device can drive the motor 402 to rotate a different number of revolutions, causing the motor 402 to rotate its output shaft 403, which in turn rotates the worm gear 404. The worm gear 404 then meshes with the worm wheel 405, causing the worm wheel 405 to rotate and drive the rotating shaft 401 to rotate. This, in turn, causes the entire housing 4 and the reflector 5 to rotate, adjusting the angle of the reflector 5. It should be noted that using the worm wheel 405 and worm 404 as the driving method reduces the rotational speed of the worm wheel 405. The speed is such that the worm gear 405 slowly drives the housing 4 and the reflector 5 to rotate, making the movement of the reflector 5 smoother. This is because the transmission ratio between the worm gear 405 and the worm 404 is calculated by dividing the number of teeth of the worm gear 405 by the number of threads of the worm 404. Since the worm gear 405 has more teeth and the worm 404 has fewer threads, a larger transmission ratio can be formed, thereby achieving a significant deceleration effect. This allows the reflector 5 to rotate at a slow speed. Reducing the rotation speed also has another advantage: after the motor 402 drives the output shaft 403 to rotate many times, it will only drive the rotating shaft 401 to rotate a small angle, which is convenient for fine adjustment.
[0038] Reference Figures 5-7 The top of the box 4 is provided with an elastic baffle 406, which is connected to the outer wall of the support rod 301. The elastic baffle 406 can move with the rotation of the support rod 301, thereby sealing the surface of the box 4 and preventing dust from falling in.
[0039] Reference Figure 8 A disc 407 is fixedly connected to one end of the rotating shaft 401 outside the box 4. A threaded rod 408 is threadedly connected to the disc 407. An annular groove 409 is provided on the outer wall of the box 4. The threaded rod 408 and the annular groove 409 are positioned corresponding to each other.
[0040] This utility model also includes an auxiliary locking structure. After the angle of the reflector 5 is adjusted and no further adjustment is needed for a long time, the threaded rod 408 on the disc 407 is rotated, thereby connecting the threaded rod 408 to the disc 407. This allows the threaded rod 408 to move until it is tightly abutting against the inner wall of the annular groove 409. It should be noted that the inner wall of the annular groove 409 is provided with an anti-slip groove, which can enhance the friction between the threaded rod 408 and the annular groove 409, thus preventing the threaded rod 408 from rotating again. At this time, the rotating shaft 401 and the box 4 no longer rotate, forming a limit and thus completing the limiting of the reflector 5.
[0041] Reference Figures 1-4 There are two brackets 101, and a fixing rod 102 is fixedly connected between the two brackets 101. A side mounting plate 103 is provided at the end of the bracket 101 away from the connecting body 1. The side mounting plate 103 is provided with a side mounting hole 104. A bottom mounting plate 105 is connected to both the bracket 101 and the side mounting plate 103. The bottom mounting plate 105 is provided with a bottom mounting hole 106.
[0042] In this embodiment, the installation can be varied. The side mounting plate 103 can be abutted against a wall or other connection location, and screws can be connected in the side mounting holes 104 for fixation. Alternatively, the bottom mounting plate 105 can be abutted against a wall or ground, and screws can be connected in the bottom mounting holes 106 for fixation, thereby completing the fixation.
[0043] Reference Figure 4 In this application, the bottom mounting plate 105 can also be abutted against objects such as the ceiling and fixed by connecting screws in the bottom mounting holes 106. In this case, the projector can be flipped over for use, unlocking another usage state.
[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
