[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example 1

[0031] See also Figure 1-Figure 4 , the present invention provides the following technical solutions:

[0032] A device for adjusting the overall optical path in laser shooting comprises a transmitting mechanism and a receiving mechanism. The transmitting mechanism transmits laser which is received by the receiving mechanism. The transmitting mechanism comprises a transmitting end housing and a transmitting end mounting base. The transmitting end housing is provided with laser holes at equal intervals. A protective cover is mounted on the laser hole. The movable plate is connected to a fixed plate through an adjusting mechanism. The adjusting mechanism comprises an adjusting bolt and an adjusting spring. A through hole is provided on the movable plate for threading the adjusting bolt. A threaded hole is provided on the fixed plate at a position corresponding to the through hole. After the adjusting bolt is inserted through the threaded hole, an adjusting spring is mounted so that its end is threadedly connected to the through hole.

[0033] In a specific embodiment of the present invention, the transmitting mechanism is responsible for transmitting lasers, while the receiving mechanism is responsible for receiving the lasers. The transmitting end housing is provided with laser holes at equal intervals, and protective covers are installed on the holes to protect the laser emission from external influences. The movable plate is connected to the fixed plate through an adjusting mechanism to allow the optical path to be adjusted. After the adjusting bolt is inserted through the threaded hole, an adjusting spring is installed so that its end is threadedly connected to the through hole. In this way, the position of the movable plate can be adjusted by rotating the adjusting bolt, thereby adjusting the emission direction of the laser.

[0034] For details, please refer to Figure 1-Figure 4 The adjusting bolt is provided with an annular groove, the fixing plate is L-shaped and a reinforcing plate is fixedly connected at the corner.

[0035] In this embodiment: the annular groove can accommodate one end of the adjustment spring, so that the spring can be compressed when the adjusting bolt is adjusted, so that the force is evenly distributed, ensuring the accuracy of the adjustment. The L-shaped structure of the fixed plate provides better stability and support, which helps to fix and support the movable plate, reduce vibration and deviation, and the reinforcing plate can significantly enhance the strength of the fixed plate at the corners to prevent deformation or damage due to force.

[0036] For details, please refer to Figure 1-Figure 4 The adjusting bolts, adjusting springs, threaded holes and through holes are respectively provided with three groups, and the installation positions of the three adjusting bolts form an equilateral triangle.

[0037] In this embodiment, by arranging the three adjustment bolts into an equilateral triangle, it can be ensured that the device is evenly stressed during the adjustment process, avoiding tilting or shifting of the device due to uneven stress. This symmetrical layout helps to maintain the balance of the device, especially when making fine adjustments, to ensure accurate alignment of the laser beam.

[0038] For details, please refer to Figure 1-Figure 4 The receiving mechanism includes a receiving end shell and a receiving end mounting base. The receiving end shell is equidistantly provided with laser receiving holes. The laser receiving holes are covered with a rubber plate, and a receiving end mirror cover is fixedly installed on the rubber plate. The rubber plate and the receiving end mirror cover are penetrated by hexagon socket head screws and then threaded into the corresponding threaded holes of the receiving end shell. Two groups of focusing lenses are provided on the receiving end mirror cover.

[0039] In this embodiment: laser receiving holes are equidistantly arranged on the receiving end housing for receiving lasers from the transmitting mechanism. The laser receiving holes are covered with a rubber sheet, the elasticity of which can make the installation of the receiving end housing and the receiving end mirror cover more tight and stable, and can also prevent environmental factors such as dust and moisture from affecting laser reception. The receiving end mirror cover is fixed to the rubber sheet by a hexagon socket head screw. This screw design is easy to tighten and disassemble, and provides good sealing performance. Two sets of focusing lenses are arranged on the receiving end mirror cover to focus the received laser beam, improve the accuracy and intensity of the beam, and ensure accurate transmission and processing of the signal.

[0040] For details, please refer to Figure 1-Figure 4 A circular groove is provided on the receiving end mirror cover near the receiving end shell, and the circular groove is used to accommodate the first group of focusing lenses. A circular ring groove is provided on the outer wall of the receiving end mirror cover with its center as the circle point, and the circular ring groove is used to accommodate the second group of focusing lenses.

[0041] In this embodiment: the circular groove opened at the receiving end mirror cover near the receiving end shell is specifically used to accommodate the first group of focusing lenses. This design allows the lens to be tightly installed on the inner side of the mirror cover, ensuring that the laser beam can be effectively focused before entering the receiving hole. The circular groove opened on the outer wall of the receiving end mirror cover with its center as the center of the circle is used to accommodate the second group of focusing lenses. At this time, the second group of lenses is located outside the first group of lenses, which is used to further adjust or optimize the focus of the light beam.

[0042] For details, please refer to the fixing plate, which is provided with an annular groove for accommodating one end of the spring, the fixing plate is provided with an annular groove for accommodating one end of the spring, a transmitting end inner shell is vertically fixed in the receiving end shell, an adjustment flange seat is equidistantly fixed to the transmitting end inner shell, the adjustment flange seat is divided into a crescent-shaped adjustment flange seat and a circular adjustment flange seat, the notch of the crescent-shaped adjustment flange seat is adapted to the visible laser mounting seat to form a circle, the crescent-shaped adjustment flange seat is connected to the transmitting end inner shell by a hexagonal thin head screw, a spring is sleeved on the hexagonal thin head screw, the spring is located between the crescent-shaped adjustment flange seat and the groove wall of the transmitting end inner shell, an aluminum tube head is passed through the center of the circular adjustment flange seat, the hollow part of the aluminum tube head accommodates a compression spring and a laser tube core, a metal lens and a hexagonal nut are respectively connected to the two ends of the aluminum tube head, and a single-pass stud is provided in the transmitting end inner shell, and the single-pass stud is threadedly connected with a cross screw with a washer to fix the transmitting end circuit board.

[0043] In this embodiment: the annular groove accommodates one end of the spring and can provide a stable fixing point for the spring, ensuring that the spring will not shift during the adjustment process, thereby maintaining the stability of the optical path adjustment. The inner shell of the transmitting end is equidistantly fixed with adjustment flange seats, and its crescent-shaped adjustment flange seat and circular adjustment flange seat are used to fine-tune the position of the laser beam to ensure accurate alignment with the receiving end. The notch of the crescent-shaped adjustment flange seat is adapted to the visible laser mounting seat to form a circle. This design allows the non-visible laser on the crescent-shaped adjustment flange seat to better adjust the angle so that it is parallel to the visible laser. The crescent-shaped adjustment flange seat is connected to the inner shell of the transmitting end through a hexagonal thin head screw. This makes the crescent-shaped adjustment flange seat easy to disassemble and maintain.

[0044] For details, please refer to the following: a support plate is installed on the movable plate, and a transmitter mounting base is installed on the support plate.

[0045] In this embodiment, the double-layer structure design of the support plate mounted on the movable plate can provide additional stability and strength, and the transmitter mounting base is mounted on the support plate, and the various components of the transmitter are fixed on this base. The entire transmitter is installed and adjusted as a unit, which simplifies the assembly and maintenance process.

[0046] For details, the transmitter mounting base is provided with mounting holes around it, the transmitter mounting base is provided with fixing holes, and the support plate is provided with position adjustment holes at positions corresponding to the mounting holes. There are two groups of position adjustment holes, and each group of position adjustment holes corresponds to two mounting holes on one side of the transmitter mounting base. The inner wall diameter of the position adjustment hole is larger than the distance between the farthest points of the two mounting holes on one side.

[0047] In this embodiment: the mounting holes are used to fix the base on the support plate, and the transmitter mounting base is also provided with fixing holes, which are used to fix the laser transmitter or other key components to ensure that they are firmly positioned on the base. The position adjustment holes on the support plate corresponding to the mounting hole positions of the transmitter mounting base allow the transmitter mounting base to be fine-tuned on the support plate to achieve more precise alignment. There are two groups of position adjustment holes, each group corresponding to two mounting holes on one side of the transmitter mounting base. This provides flexibility for the installation method, and you can choose between different mounting hole combinations to meet different installation requirements.

[0048] For details, an elliptical hole is provided at the center of the support plate, the elliptical hole corresponds to the mounting circular hole provided on the mounting base of the transmitting end, and the distance between the farthest points of the elliptical hole is greater than the diameter of the mounting circular hole.

[0049] In this embodiment: the elliptical hole corresponds to the mounting circular hole opened in the transmitter mounting base, which allows the transmitter mounting base to have a larger adjustment range on the support plate to ensure that the laser transmitter can be accurately aligned with the target. The distance between the farthest points of the elliptical hole is greater than the diameter of the mounting circular hole, which means that even if the mounting circular hole is offset to a certain extent in the elliptical hole, the transmitter mounting base can still be fixed on the support plate. This design provides a larger fault tolerance space, making the installation process more flexible.

[0050] The working principle and use process of the present invention are as follows: the invisible laser tube is fixedly installed on the invisible crescent-shaped adjustment flange seat, and the cooperation is a threaded cooperation; three compression springs are installed in the corresponding countersunk holes of the crescent-shaped adjustment flange seat, and fixed to the inner tank of the transmitting end with three M3*18 bolts, and other invisible laser tubes and flanges are installed and fixed in the above manner; the visible laser mounting seat is directly fixed to the inner tank of the transmitting end with M3*8 bolts. Since the visible laser mounting seat and the inner tank of the transmitting end are fixedly installed, the laser signal emitted by the visible laser tube on the visible laser mounting seat forms a fixed angle with the inner tank of the transmitting end. When the inner tank of the transmitting end rotates a certain angle, the visible laser will also rotate a corresponding angle; the crescent-shaped adjustment flange seat and the circular adjustment flange seat are movably connected to the inner tank of the transmitting end by springs and bolts. A surface can be determined by three points. By tightening the three hexagonal thin head screws of the adjustment flange seat, the invisible laser on the crescent-shaped adjustment flange seat and the circular adjustment flange seat can be adjusted to any angle within a certain range. Using this principle, all other invisible lasers can be adjusted to be parallel to the visible laser.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
