[0026] The following will refer to the appendix in the embodiments of this utility model. Figures 1-7The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Example:

[0028] like Figures 1 to 7 As shown, this utility model discloses a novel semiconductor laser, including a laser housing 1. A light-transmitting lens 2 is provided on the front end of the laser housing 1. In addition, a rotating shaft 3 is fixedly connected to the front side of the laser housing 1 above the light-transmitting lens 2. A left blocking half cover 4 and a right blocking half cover 5 are rotatably connected to the rotating shaft 3. When the left blocking half cover 4 and the right blocking half cover 5 are closed, they are used to wrap the light-transmitting lens 2. Furthermore, a driving mechanism is provided on the laser housing 1 for driving the left blocking half cover 4 and the right blocking half cover 5 to rotate apart or rotate together around the rotating shaft 3.

[0029] Furthermore, a rotation track groove 11 is provided on the front side of the laser housing 1. Each rotation track groove 11 is provided on the rear side of the left shielding half cover 4 and the right shielding half cover 5. Each of the left shielding half cover 4 and the right shielding half cover 5 is fixedly connected to a sliding post 6 that passes through the rotation track groove 11. The driving mechanism is used to drive the sliding post 6 to slide on the rotation track groove 11. By providing a rotation track groove 11 on the front side of the laser housing 1 and providing sliding posts 6 on the left shielding half cover 4 and the right shielding half cover 5, the shielding half covers can be precisely opened and closed along a specific trajectory by the driving mechanism, thereby improving the reliability and stability of the protective device.

[0030] Specifically, two drive mechanisms are provided inside the laser housing 1, located behind the left and right blocking half-covers 4 and 5, respectively. Each drive mechanism includes a sliding frame 8 and a lifting mechanism. The sliding frame 8 slides up and down on the laser housing 1, while the lifting mechanism drives the sliding frame 8 to slide up and down. A horizontal long slot 81 is provided on the sliding frame 8, and the sliding column 6 is movably fitted within the horizontal long slot 81. This design of the sliding frame 8 and lifting mechanism allows the sliding frame 8 to slide vertically up and down, thereby driving the sliding column 6 to move within the rotation trajectory slot 11. This achieves precise control of the left and right blocking half-covers 4 and 5, while also reducing space requirements.

[0031] The lifting mechanism specifically includes a motor 91 and a lead screw 92. The motor 91 is fixed inside the laser housing 1, and the lead screw 92 is fixedly connected to the output shaft of the motor 91. The sliding frame 8 is provided with a threaded hole 82 for threaded engagement with the lead screw 92. The lifting mechanism composed of the motor 91 and the lead screw 92 not only simplifies the structural design, but also ensures the stable up and down movement of the sliding frame 8, further enhancing the reliability and response speed of the entire system.

[0032] The specific structure of the sliding frame 8 sliding up and down on the laser housing 1 is as follows: a vertical groove 12 is provided inside the laser housing 1, and a slider 83 is provided on the sliding frame 8 for sliding up and down on the vertical groove 12. The vertical groove 12 is provided inside the laser housing 1, and the slider 83 on the sliding frame 8 slides up and down in this groove, which ensures the smooth movement of the sliding frame 8 and avoids displacement errors caused by vibration or other factors.

[0033] The specific structure of the left blocking half cover 4 and the right blocking half cover 5 rotatably set on the rotating shaft 3 is as follows: the left blocking half cover 4 includes an upper left sleeve 41, and the right blocking half cover 5 includes a lower right sleeve 51. The upper left sleeve 41 and the lower right sleeve 51 are both rotatably fitted on the rotating shaft 3, and the upper left sleeve 41 is located in front of the lower right sleeve 51.

[0034] In this utility model, the left half-cover 4 and the right half-cover 5 are both provided with magnetic strips 7 on their lower side where they are joined together. The magnetic strips 7 can ensure that the two fit more tightly in the closed state, improve the protective effect, and also facilitate opening and closing.

[0035] The working principle of this utility model is as follows: When it is necessary to protect the light-transmitting lens 2, the motor 91 starts and drives the lead screw 92 to rotate.

[0036] The sliding frame 8 slides up and down: the rotation of the lead screw 92 causes the sliding frame 8 to slide up and down along the vertical groove 12. When the motor 91 rotates forward, the sliding frame 8 moves downward; conversely, when the motor 91 rotates in reverse, the sliding frame 8 moves upward.

[0037] The sliding column 6 moves along the track groove: the horizontal long groove 81 on the sliding frame 8 cooperates with the sliding column 6. When the sliding frame 8 moves downward, the sliding column 6 moves downward along the rotation track groove 11, causing the left half-cover 4 and the right half-cover 5 to rotate downward around the rotation axis 3 and close, covering the light-transmitting lens 2. Figure 5 and Figure 7 As shown.

[0038] Reverse operation to open: When the laser is needed, motor 91 reverses, sliding frame 8 moves upward, and sliding column 6 moves upward along rotation track groove 11, causing the left blocking half cover 4 and right blocking half cover 5 to rotate upward and separate, revealing the light-transmitting lens 2. Figure 1 ,Figure 3 as well as Figure 6 As shown.

[0039] Magnetic sheet 7 assists in closing: During the closing process, the magnetic sheet 7 at the bottom of the left half cover 4 and the right half cover 5 attract each other, ensuring that the two fit tightly together and form an effective dust barrier.

[0040] The structural design of this utility model not only significantly reduces the space requirements of the overall device, but also integrates all driving components within the laser housing 1, improving the overall aesthetics and portability of the equipment. Simultaneously, the ingenious mechanical design ensures that the protective device is easy to operate and runs stably.

[0041] It should also be noted that the terms used in this utility model, such as "front", "rear", "vertical", "horizontal", 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 limiting the scope of protection of this utility model.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
