Technical Field

[0001] This utility model relates to the field of optical frame technology, and in particular to a device for laser guidance. Background Technology

[0002] Laser is a special type of light source. Compared with ordinary light sources (incandescent lamps, LED lamps), lasers have characteristics such as high directionality, high monochromaticity, high brightness, and high coherence. With the development of the times, lasers have been widely used in various fields such as industry, medicine, scientific research, communication, and military. Therefore, in order to adapt to the development of the times, various laser emitters have emerged one after another.

[0003] Among the various types of laser emitters, some laser emitters are equipped with corresponding guiding devices to guide the laser to a designated position, while other laser emitters are not equipped with corresponding guiding devices, so these laser emitters need to be equipped with an additional guiding device.

[0004] However, the existing guiding devices have relatively limited functions and cannot meet the needs of daily use, such as the inability to adjust the height or angle of the laser. Utility Model Content

[0005] This application provides a device for laser guidance to solve the problems in the background art described above.

[0006] This application provides a device for laser guidance, including a column with two sliding blocks mounted on it. A guiding device is mounted on each sliding block. The guiding device includes a mounting block, a lens frame, a movable plate, and an adjustment mechanism. The mounting block is mounted on the sliding block, the adjustment mechanism connects the mounting block and the movable plate, and the lens frame is mounted on the movable plate.

[0007] Furthermore, the column has a groove, and the sliding block has a protrusion that mates with the groove.

[0008] Furthermore, a through groove is provided on the sliding block, a second protrusion is provided on one side of the through groove, a third protrusion is provided on the other side of the through groove, the second protrusion and the third protrusion are fixedly connected to the sliding block, and a fastening bolt is threaded between the second protrusion and the third protrusion.

[0009] Furthermore, the adjustment mechanism includes an adjustment rod, a ball bearing, and a spring. Several adjustment rods are threaded onto the mounting block, and the ball bearing is rotatably connected to the adjustment rod. A movable groove is provided on the movable plate, and the ball bearing is located in the movable groove. The movable plate and the mounting block are connected by a spring.

[0010] Furthermore, the mounting block has a through hole one, the movable plate has a through hole two, a sleeve one is installed in the through hole one, a sleeve two is installed in the through hole two, one end of the spring is fixedly connected to the sleeve one, and the other end of the spring is fixedly connected to the through hole two.

[0011] Furthermore, a handle is fixedly connected to the second sleeve.

[0012] Furthermore, the movable groove is chamfered.

[0013] Furthermore, the frame is divided into a mounting part and a rotating part. The rotating part is rotatably connected to a movable plate. Two fastening bolts are threaded onto the movable plate, and one end of the fastening bolts abuts against the rotating part.

[0014] In summary, the beneficial effects of the laser guidance device in this application are as follows: the device, through the cooperation structure of the groove on the column and the protrusion on the sliding block, enables the sliding block to have precise guidance when moving along the column, avoiding deviation and ensuring the position adjustment accuracy of the laser guidance component.

[0017] The following description is merely a preferred embodiment of this utility model, and the scope of protection is not limited to this embodiment. All technical solutions falling within the scope of this utility model should be considered within the protection scope of this utility model. It should also be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.

[0018] like Figures 1 to 5 As shown, a device for laser guidance includes a column 1, two sliding blocks 2 on the column 1, which can slide on the column 1. A groove 4 is formed on the column 1, which is set along the height direction of the column 1. A protrusion 5 is formed on the sliding block 2, which fits into the groove 4, making the sliding block 2 more stable during sliding and preventing rotation. A through groove 6 is formed on the sliding block 2. A second protrusion 7 is formed on one side of the through groove 6 and is fixedly connected to the sliding block 2. A third protrusion 8 is formed on the other side of the through groove 6 and is fixedly connected to the sliding block 2. A fastening bolt 9 is threadedly connected to the second protrusion 7 and the third protrusion 8. The movement and fixation of the sliding block 2 can be adjusted by rotating the fastening bolt 9.

[0019] Furthermore, a guide device 3 is installed on each sliding block 2. The guide device 3 includes a mounting block 301, a frame 302, a movable plate 303, and an adjustment mechanism 304. The mounting block 301 is fixedly connected to the sliding block 2 and is L-shaped. The adjustment mechanism 304 is mounted on the mounting block 301. The movable plate 303 is connected to the mounting block 301 through the adjustment mechanism 304. The frame 302 is rotatably connected to the movable plate 303, and the frame 302 is located on the upper sliding block 2. The lens frame 302, located on the lower sliding block 2, faces upwards, and the lenses on both lens frames 302 are installed at a 45° angle. The lens frame 302 is divided into a mounting part 201 and a rotating part 3021. The mounting part 201 is used to install the lenses. The movable part is rotatably connected to the movable plate 303. The movable part can rotate on the movable plate 303. The second fastening bolt 3022 is threadedly connected to the movable plate 303. When one end of the second fastening bolt 3022 abuts against the rotating part 3021, the entire lens frame 302 can be fixed.

[0020] Furthermore, the adjusting mechanism 304 includes adjusting rods 3041, balls 3042, and springs 3043. An adjusting rod 3041 is installed at each of the three corners of the mounting block 301. The adjusting rods 3041 are threadedly connected to the mounting block 301. The balls 3042 are rolled onto the tops of the adjusting rods 3041. A receiving groove corresponding to the number of adjusting rods 3041 is formed on the movable plate 303, and the balls 3042 are located within the receiving groove. A chamfer 16 is formed on the receiving groove. A spring 3043 is formed on the mounting block 301. The device has several through holes 11 and several through holes 12 on the movable plate 303. The through holes 11 and 12 are concentric. A sleeve 13 is movably connected in the through hole 11, and a sleeve 14 is movably connected in the through hole 12. One end of a spring 3043 is located inside the sleeve 13 and is fixedly connected to it. The other end of the spring 3043 is located inside the sleeve 14 and is fixedly connected to it. Under the tension of the spring 3043, the ball 3042 fits into the receiving groove. The guide device 3 guides the ball 3042 with an L-shaped force. The mounting block 301 serves as a fixed base. The adjusting rods 3041 at its three corners are rigidly connected to the mounting block 301 via threads. Under the natural tension of the spring 3043, the movable plate 303 is continuously pulled towards the mounting block 301, causing the receiving groove on the movable plate 303 to tightly engage with the ball bearing 3042 at the top of the adjusting rod 3041. At this point, the movable plate 303 is in a stable position, providing a reference for subsequent fine-tuning. The adjusting rods 3041 at the three corners of the mounting block 301 are triangularly distributed. By independently or in combination adjusting the adjusting rods 3041 at different positions... 41. It can achieve precise fine-tuning of the movable plate 303 in different dimensions. After the fine-tuning is completed, the rotation of the adjusting rod 3041 is stopped, and the axial position of the adjusting rod 3041 is fixed. Its pushing force on the ball 3042 and the tension of the spring 3043 form a new force balance: the spring 3043 continues to pull the movable plate 303, so that the receiving groove is always in close contact with the ball 3042, avoiding the separation of the ball 3042 from the groove wall due to vibration or external force interference, thereby ensuring that the movable plate 303 is maintained in the adjusted target position and achieving stable locking of laser guidance accuracy.

[0021] Furthermore, a handle 15 is fixedly connected to the second sleeve 14. If the spring 3043 is not under enough tension, the second sleeve 14 can be pulled out by pulling the handle 15, and then the spring 3043 can be cut. At this time, the first sleeve 13 can slide out from the first through hole 11. After cleaning the spring 3043 in the first sleeve 13, a new spring 3043 is installed in the first sleeve 13. Then, the other end of the spring 3043 is inserted from the first through hole 11 and passes through the first through hole 11 into the second through hole 12. Then, the other end of the spring 3043 is fixed to the second sleeve 14. Under the tension of the spring 3043, the first sleeve 13 is restricted in the first through hole 11, and the second sleeve 14 is restricted in the second through hole 12.

[0022] Working principle of the utility model: When it is necessary to adjust the height of the sliding block 2, loosen the fastening bolt 9, and the sliding block 2 can smoothly slide along the groove 4 to the target position; after the height is determined, tighten the fastening bolt 9, and the axial force of the bolt will cause the second protrusion 7 and the third protrusion 8 to move towards the center of the through groove 6, thereby clamping the column 1 and realizing the rigid fixation of the sliding block 2 and the column 1, providing a stable installation benchmark for the upper guide device 3. When it is necessary to adjust the angle of the frame 302, loosen the fastening bolt 3022 on the movable plate 303, and the rotating part 3021 of the frame 302 can rotate freely around the movable plate 303. After the angle is adapted to the laser guidance direction, tighten the fastening bolt 3022 so that one end of it abuts against the rotating part 3021, realizing the rigid fixation of the angle of the frame 302, avoiding angle deviation during the guidance process. At the same time, the adjustment rods 3041 with the three corners of the mounting block 301 are triangularly distributed, and the movable plate 303 can be accurately displaced by independent or combined rotation to adapt to different laser guidance position requirements.
