[0027] Reference Figure 1-7 The image shown is a preferred embodiment of the present invention.

[0028] The lens module's bokeh adjustment structure includes a lens body 1, a bokeh module 2, and an adjustment structure 3. The bokeh module 2 is movably mounted on the lens body 1. The adjustment structure 3 includes an upward adjustment module 31 and a downward adjustment module 32, which are arranged vertically opposite to each other along the bokeh module 2. The upward adjustment module 31 includes an upper horizontal adjustment rod 311 and an upper vertical adjustment rod 312. The upper horizontal adjustment rod 311 passes through the bokeh module 2 and extends to the lens body 1. The upper part of the upper vertical adjustment rod 312 is movably connected to the lens body 1. The lower part of the module 32 is connected to the light spot module 2. The lower adjustment module 32 includes a lower horizontal adjustment rod 321 and a lower vertical adjustment rod 322. The lower horizontal adjustment rod 321 passes through the light spot module 2 and extends to the lens body 1. The lower part of the lower vertical adjustment rod 322 is movably connected to the lens body 1, and the lower part of the lower vertical adjustment rod 322 is connected to the light spot module 2. The upper horizontal adjustment rod 311 and the lower horizontal adjustment rod 321 are used to adjust the left and right angles of the light spot projection of the light spot module 2, respectively. The upper vertical adjustment rod 312 and the lower vertical adjustment rod 322 are used to adjust the pitch angle of the light spot projection of the light spot module 2, respectively.

[0029] The aforementioned lens module's beam adjustment structure, during use, requires the beam module 2 to emit a straight beam, which needs to coincide with the center line of the lens body 1 within a certain distance to improve image clarity. Users can adjust the beam module 2 relative to the lens body 1 laterally using the upper horizontal adjustment lever 311 and the lower horizontal adjustment lever 321, thereby adjusting the beam projection direction left and right. The upper vertical adjustment lever 312 and the lower vertical adjustment lever 322 can adjust the beam angle, thus adjusting the beam projection direction up and down until the beam coincides with the center line of the lens body 1 within a certain distance, ensuring the aiming effect of the scope. This adjustment is simple, convenient, and quick, and easy for users to operate.

[0030] By coordinating the upward adjustment module 31 and the downward adjustment module 32, the left and right tilt angles can be adjusted, so that the projected light spot coincides with the center line of the lens body 1.

[0031] The lens body 1 includes a lens housing with a mounting cavity that is recessed inward. The light spot module 2 is movably embedded in the mounting cavity. Under the action of the mounting cavity, the cooperation between the light spot module 2 and the lens body 1 also plays a protective role in the setting of the light spot module 2.

[0032] The mounting cavity includes an upper cavity platform 13, a middle cavity, and a lower cavity platform 14. The spot module 2 is movably embedded in the middle cavity. The upper horizontal adjustment rod 311 passes through the spot module 2 and extends to the upper cavity platform 13, and the upper horizontal adjustment rod 311 is threadedly connected to the upper cavity platform 13. The lower horizontal adjustment rod 321 passes through the spot module 2 and extends to the lower cavity platform 14, and the lower horizontal adjustment rod 321 is threadedly connected to the lower cavity platform 14.

[0033] The middle cavity acts as a limiter and positioner for the light spot module 2, improving the stability of the light spot module 2. The left and right positions of the projected light spot can be adjusted by the cooperation of the upper cavity platform 13 and the upper horizontal adjustment rod 311, and by the cooperation of the lower cavity platform 14 and the lower horizontal adjustment rod 321.

[0034] The light spot module 2 includes a light spot body, an upper fixed plate, and a lower fixed plate. The two ends of the light spot body are respectively connected to the upper fixed plate and the lower fixed plate. The light spot body is embedded in the middle cavity, and the middle cavity is used to position the light spot body. The upper fixed plate is arranged in an overlapping and abutting arrangement with the upper cavity platform 13. The upper horizontal adjustment rod 311 passes through the upper fixed plate and extends to the upper cavity platform 13. The lower fixed plate is arranged in an overlapping and abutting arrangement with the lower cavity platform. The lower horizontal adjustment rod 321 passes through the lower fixed plate and extends to the upper cavity platform 13.

[0035] In this way, the combined action of the upper fixed plate and the upper cavity stage 13 enhances the stability of the light spot module 2 and improves the adjustment stability of the upper horizontal adjustment rod 311. The combined action of the lower fixed plate and the lower cavity stage 14 enhances the stability of the light spot module 2 and improves the adjustment stability of the lower horizontal adjustment rod 321.

[0036] The upper adjustment module 31 includes two upper horizontal adjustment rods 311, which are arranged at intervals and are simultaneously inserted through the upper fixed plate to the upper cavity stage 13; the lower adjustment module 32 includes two lower horizontal adjustment rods 321, which are arranged at intervals and are simultaneously inserted through the lower fixed plate to the lower cavity stage 14.

[0037] In this way, the adjustment stability of the upper horizontal adjustment rod 311 is improved by the cooperation of the two upper horizontal adjustment rods 311, and the adjustment stability of the lower horizontal adjustment rod 321 is improved by the cooperation of the two lower horizontal adjustment rods 321.

[0038] The lens housing has a housing fixing post 12, which is arranged in a protruding manner and is located in the mounting cavity. The housing fixing post 12 is movably embedded in the light spot module 2 and is used to position the light spot module 2. Under the action of the housing fixing post 12, the light spot module 2 is positioned and limited, thereby improving the stability of adjustment.

[0039] The upper horizontal adjustment rod 311 and the lower horizontal adjustment rod 321 adjust the left and right angles of the light spot projection of the light spot module 2 along the axial direction of the shell fixed column 12, respectively. The axial length of the upper horizontal adjustment rod 311 and the axial length of the lower horizontal adjustment rod 321 are less than the axial length of the shell fixed column 12, respectively. In this way, the range of left and right adjustment is less than the positioning distance of the shell fixed column 12, ensuring the stability of the light spot module 2.

[0040] The lens housing includes an upper housing plate 15 and a lower housing plate 16, with a mounting cavity located between the upper housing plate 15 and the lower housing plate 16; an upper longitudinal adjustment rod 312 passes through the upper housing plate 15 and movably passes through the spot module 2, and the upper longitudinal adjustment rod 312 is threadedly connected to the spot module 2; a lower longitudinal adjustment rod 322 passes through the upper housing plate 15 and movably passes through the spot module 2, and the lower longitudinal adjustment rod 322 is threadedly connected to the spot module 2.

[0041] The pitch angle of the projected light spot can be adjusted by the cooperation of the upper shell plate 15 with the upper longitudinal adjustment rod 312 and the lower shell plate 16 with the lower longitudinal adjustment rod 322.

[0042] The upward adjustment module 31 includes two upper vertical adjustment rods 312, which are arranged at intervals and are synchronously inserted through the upper shell plate 15 to the light spot module 2. The downward adjustment module 32 includes two lower vertical adjustment rods 322, which are arranged at intervals and are synchronously inserted through the lower shell plate 16 to the light spot module 2.

[0043] In this way, the adjustment stability of the upper longitudinal adjustment rod 312 is improved by the cooperation of the two upper longitudinal adjustment rods 312, and the adjustment stability of the lower longitudinal adjustment rod 322 is improved by the cooperation of the two lower longitudinal adjustment rods 322.

[0044] The lens body 1 includes multiple lens bodies 11, which are arranged at intervals along a straight line. Each lens body 11 forms a lens-coupling area along a straight line. The light spot module 2 projects a light spot that overlaps with the lens-coupling area. With the cooperation of each lens body 11, functions such as zoom and magnification are achieved.

[0045] 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 and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
