Description

Technical Field

[0001] This utility model relates to the field of aiming scope devices, and in particular to a holographic aiming scope with single-piece dry plate imaging. Background Technology

[0002] A holographic sight is an auxiliary device that helps shooters obtain a wider field of view for accurate aiming. Through a holographic plate and laser emitter, it avoids parallax effects, achieving low aberration and distortion-free results compared to spherical collimators, thus improving overall shooting accuracy. However, currently available holographic sights are overly complex in structure, inconvenient to maintain, and have poor overall reliability, affecting the overall user experience. Furthermore, their low production efficiency and inconsistent manufacturing quality fail to meet current usage requirements. Utility Model Content

[0003] The purpose of this invention is to provide a holographic sight with single-piece dry plate imaging, which solves the technical problems of complex structure, high production cost and poor stability in the prior art, and achieves the technical effects of simplifying the overall structure, reducing production cost and improving the overall imaging stability and aiming effect.

[0004] To achieve the aforementioned objectives, the technical solution adopted by this utility model is as follows:

[0005] A holographic sight with single-plate imaging includes a scope barrel mounting base and a light-emitting structure. The scope barrel and the mounting base are integrally formed. The scope barrel has openings at both ends, which are coaxially arranged. A narrow-band reflector and an eyepiece are respectively fixed inside the openings. A holographic plate is located on the side of the narrow-band reflector closest to the eyepiece. The holographic plate is arranged perpendicular to the axis of the scope barrel. A battery compartment is located below the narrow-band reflector and inside the mounting base. A battery is detachably connected inside the battery compartment. A power receiving module is located on the side of the battery away from the narrow-band reflector. The light-emitting structure is located below the eyepiece and includes a reflector, a laser emitter, and an adjustment structure. The reflector is tilted at 45° towards the holographic plate. The laser emitter is located inside the adjustment structure and is movably mounted on the mounting base. The laser emitter is located below the reflector. The lower end of the laser emitter has a line connecting to the power receiving module and cooperates with the reflector to image on the holographic plate.

[0006] As an improvement, the inner side of the lens barrel has multiple sets of reinforcing ribs perpendicular to the axial direction, and the inner side of the mounting base has an inclined surface tilted towards the reflector to satisfy stray light elimination. The wavelength of the narrow-band reflective objective lens is 650nm to prevent the laser from penetrating the holographic plate and exposing the light source.

[0007] As an improvement, a button is provided on one side of the mounting base, which is located near the power connection module and is used to control the power supply of the laser emitter. A mounting cylinder is provided on the side of the battery away from the power connection module. The inner side of the mounting cylinder has a limit groove to limit the position of the battery. The outer side of the mounting cylinder has threads for detachable connection with the battery compartment.

[0008] As an improvement, a guide rail clamp is fixed below the mounting base, and a guide rail tenon is rotatably connected to the inner side of the guide rail clamp. A sliding plate is connected to one end of the guide rail tenon, and the sliding plate is slidably connected to the guide rail clamp to cooperate with the guide rail for fixation.

[0009] As an improvement, the adjustment structure includes a base plate, a height adjustment push block, and a lateral adjustment push block. The base plate is fixedly connected to the bottom end of the mounting base. The inner side of the base plate has multiple sets of sliding grooves. The lower end of the height adjustment push block has a protrusion that slides through the sliding groove. One side of the height adjustment push block is threaded with an adjustment knob A, which is rotatably connected to the mounting base. A sliding seat is movably sleeved on the outer side of the laser emitter. The lower end of the sliding seat has a protrusion that slides through the sliding groove of the base plate. The side of the sliding seat away from the height adjustment push block has a spring. The two ends of the spring are respectively fixed against the sliding seat and the mounting base. The side of the height adjustment push block away from the adjustment knob A has an inclined surface. The sliding seat near the height adjustment push block also has an inclined surface. The height adjustment push block is used to adjust the X-axis position of the laser emitter and change the imaging height position on the holographic plate.

[0010] As an improvement, the lateral adjustment push block is located inside the sliding seat. One end of the lateral adjustment push block is threaded with an adjustment knob B. The adjustment knob B is located on the same side as the adjustment knob A and is rotatably connected to the mounting base. A follower light-transmitting block is provided between the laser emitter and the sliding seat. The lower end of the laser emitter has a connecting plate that is fixedly connected to the follower light-transmitting block. The upper end of the follower light-transmitting block has a through hole for the laser emitter to illuminate the reflector. The side of the follower light-transmitting block near the lateral adjustment push block has a sliding groove and is slidably connected to the lateral adjustment push block. The side of the follower light-transmitting block away from the lateral adjustment push block has a spring. The two sides of the spring are respectively abutted and fixed to the sliding seat and the follower light-transmitting block to fit the follower light-transmitting block with the lateral adjustment push block. The lateral adjustment push block is used to adjust the Y-axis position of the laser emitter and change the horizontal position of the image on the holographic plate.

[0011] The beneficial effects of this utility model are as follows: by setting an integrated lens barrel and mounting base structure, the overall volume of the device is reduced, while the imaging optical path is optimized and the complexity of parts is reduced, thereby reducing the overall production cost. The overall imaging effect is improved by setting a narrow-band reflective objective lens and a holographic plate, while avoiding exposure of the light source. The imaging position can be easily adjusted by setting an adjustment structure, thereby improving the aiming effect. Attached Figure Description
