Description

Technical Field

[0001] This utility model relates to the field of gun light accessories technology, and in particular to a laser sight adjustment mechanism for gun lights, which is suitable for auxiliary aiming devices for firearms such as toy guns, and can achieve precise angle adjustment of the laser beam in outdoor shooting, tactical training and other scenarios. Background Technology

[0002] In existing technologies, the adjustment mechanism of a gun light laser sight mainly suffers from the following problems: Low adjustment accuracy: Most mechanisms use a single spring + single screw adjustment method. After the screw is loosened, the spring reset deviation is large, which causes the laser beam to fail to return to the initial position accurately. Complex structure: Some adjustment mechanisms require gears, connecting rods and other transmission components to achieve angle adjustment, resulting in a large number of parts and a tendency for adjustment failures due to component wear; Cumbersome to operate: Adjustment requires repeated disassembly of the outer casing or the use of special tools, making it impossible to quickly calibrate during firing and affecting efficiency; Poor stability: After prolonged use, the adjusting screws are prone to loosening, causing the laser beam to deviate and requiring frequent recalibration, increasing maintenance costs. To address this issue, a new adjusting mechanism for the laser sight in a gun lamp is proposed. Summary of the Invention

[0003] To achieve the above objectives, the present invention adopts the following technical solution: An adjustment mechanism for a laser sight in a gun lamp includes a main body, a bracket, a laser emitter, adjusting springs, and hexagonal head screws. The bracket is fixedly installed inside the main body. The laser emitter is mounted on the bracket, with its front end having an arc-shaped structure. The laser emitter engages with the bracket via the arc-shaped structure and can rotate around the engagement point. Two adjusting springs are provided, located on the left and bottom sides of the bracket respectively. The two ends of the two adjusting springs are fixedly connected to the bracket and the laser emitter, respectively, and are in a pre-compressed state after assembly. Two hexagonal head screws are provided, located on the top and right sides of the bracket respectively. Both hexagonal head screws are threadedly connected to the bracket and abut against the outer wall of the laser emitter. When the hexagonal head screw on the top or right side is turned to move it towards the laser emitter, the hexagonal head screw pushes the laser emitter to compress the adjusting spring on the corresponding side, thereby adjusting the angle of the laser beam in that direction. When the hexagonal head screw is turned in the opposite direction to move it away from the laser emitter, the adjusting spring on the corresponding side returns to its original position and pushes the laser emitter to move in the opposite direction, thereby adjusting the angle of the laser beam in the opposite direction.

[0004] Furthermore, it also includes hexagonal socket head cap screws, which are fixed to the main body and used to install hexagonal socket head cap adjusting screws.

[0005] Furthermore, the adjusting spring is a compression spring, and its pre-compression state ensures that the laser emitter is always subjected to spring force, which is used to provide a reset function and maintain stability during the adjustment process.

[0006] Furthermore, the front end of the main body is also equipped with a lampshade, a lens, and a lens sealing ring; the lampshade is fixed to the front end of the main body, the lens is located inside the lampshade, and the lens sealing ring is sandwiched between the lens and the lampshade to achieve a sealed dustproof effect at the front end of the main body; the lampshade is also equipped with a light cup, a lamp plate, and an O-ring to achieve auxiliary lighting function.

[0007] Furthermore, it also includes an adjustment module, which is installed below the main body and includes a pressure block screw, a pressure block, a fixing nut, a positioning pin, a clamping block, a spring, a male rail adjustment tooth, a female rail adjustment tooth, and a movable screw. By using the movable screw in conjunction with the fixing nut, pressure block, and clamping block, the main body is securely installed on the Picatinny rail or other standard rail of the firearm.

[0008] Furthermore, a tail cover is installed at the rear of the main body. Inside the main body and the tail cover, there are battery cells, a tail cover sealing ring, and a main board. The main board integrates a charging interface and buttons, and a USB rubber plug is provided at the charging interface for waterproofing.

[0009] Furthermore, the buttons are exposed outwards, and the button caps are mounted on the back of the tail cover via a hinge, abutting against the buttons for easy user operation.

[0010] Furthermore, the tail cap is secured to the rear of the main body with screws and a silicone plug, ensuring a tight seal and structural stability.

[0011] Compared with the prior art, the present invention has the following significant advantages: Precise adjustment and good reset performance: The adjustment principle of "push-spring" is adopted, which uses pre-compression springs on both sides and adjustment screws on the opposite side. This eliminates transmission gaps, and there is no rebound after adjustment. The springs always provide reset force, ensuring that the laser beam can be stably maintained after fine adjustment and can return accurately.

[0012] Simple structure and high reliability: The core adjustment mechanism consists of only a bracket, laser, spring and screw. The number of parts is small and the structure is compact, which reduces manufacturing costs and assembly difficulty. At the same time, it reduces the risk of failure caused by complex mechanisms and has a long service life.

[0013] Easy to operate: Users only need an Allen wrench to adjust the angle in both the up and down and left and right dimensions without disassembling any parts, which can achieve quick on-site calibration and greatly improve the efficiency of use.

[0014] High stability: The adjusting screw is directly connected to the bracket via threads. Combined with the continuous resistance of the preload spring, it can effectively resist the vibration generated during firearm firing, prevent the screw from loosening on its own, and ensure long-term stability.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] To make the technical solution and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0021] Please see Figures 1-4 As shown, the adjustment mechanism of the laser sight in the gun light disclosed in this utility model uses the main body 7 as the core mounting frame. The main body 7 is made of high-strength engineering plastic or lightweight alloy, which ensures structural stability while controlling the overall weight, adapting to the auxiliary aiming needs of toy guns and various firearms, and is especially suitable for outdoor shooting, tactical training and other scenarios. Inside the main body 7, a bracket 9 is also fixedly installed. The bracket 9 is tightly connected to the inner wall of the main body 7 by screws 8. Its structural design must be adapted to the shape of the laser emitter 10 to provide a stable mounting base for the laser emitter 10.

[0022] The laser emitter 10 is mounted on the bracket 9, and its front end is specially designed with an arc-shaped structure. This arc-shaped structure precisely engages with the pre-set arc-shaped groove on the bracket 9, allowing the laser emitter 10 to rotate flexibly around the engagement point. This rotational structure is the key foundation for adjusting the laser beam angle. At the same time, the arc-shaped mating surface is polished to reduce frictional resistance during rotation, ensuring a smooth and uninterrupted adjustment process. To achieve the stability of the laser emitter 10's reset and adjustment, an adjusting spring 11 is also provided on the left side and bottom of the bracket 9. This adjusting spring 11 is a compression spring, and its two ends are fixedly connected to the bracket 9 and the laser emitter 10 by welding or snap-fitting. After assembly, it is always in a pre-compressed state. This pre-compressed state ensures that the laser emitter 10 is always subjected to a continuous and uniform spring force, which not only prevents the laser emitter 10 from loosening or shifting in the non-adjusted state, but also provides reliable power for reset after subsequent adjustment.

[0023] The angle adjustment is achieved in conjunction with the adjusting spring 11 by two hexagonal adjusting screws 13 located on the top and right side of the bracket 9. The hexagonal adjusting screws 13 are connected to the pre-set threaded holes on the bracket 9 by precision threads, and their ends directly abut against the outer wall of the laser emitter 10. When adjusting the laser beam angle, if adjustment is needed in a certain direction (such as upward or right), the user only needs to use an Allen wrench to turn the corresponding Allen adjusting screw 13 clockwise, moving the screw towards the laser emitter 10. At this time, the end of the screw will push the laser emitter 10 to rotate around the engagement point, and simultaneously compress the adjusting spring 11 on the corresponding side until the laser beam reaches the target angle. During the adjustment process, the reaction force of the spring can provide real-time feedback on the adjustment force, helping the user to accurately control the adjustment range. If adjustment is needed in the opposite direction (such as downward or left), simply turn the Allen adjusting screw 13 in the opposite direction, gradually moving the screw away from the laser emitter 10. At this time, the compressed adjusting spring 11 will reset under its own elastic force, thereby pushing the laser emitter 10 to rotate in the opposite direction until the laser beam returns to the required angle. The entire adjustment process does not require disassembling any parts, and precise adjustment in both the up / down and left / right dimensions can be completed with only a single tool, greatly improving operating efficiency.

[0024] To further ensure the installation stability of the hexagonal headstock adjusting screw 13, a hexagonal headstock fixing screw 12 is also fixedly installed on the main body 7, which is threadedly connected to the main body 7.

[0025] At the front end of the main body 7, components for auxiliary lighting and protection are also installed. The lampshade 1 is fixed to the front end of the main body 7 by threaded connection or snap-fit. The lampshade 1 is made of transparent or semi-transparent impact-resistant material, which can protect the internal components from external impact and dust intrusion. Inside the lampshade 1, a lens 3 is also provided. The lens 3 is made of high light transmittance optical glass, and a lens sealing ring 2 is sandwiched between its edge and the lampshade 1. The sealing ring 2 is made of aging-resistant rubber material. It achieves a seal between the lens 3 and the lampshade 1 through compression deformation, preventing dust and moisture from entering the interior of the lampshade 1 when used outdoors. Meanwhile, the lamp cover 1 is also equipped with a light cup 4, a lamp plate 5, and an O-ring 6. The light cup 4 adopts a parabolic structure, which can focus the light emitted by the lamp plate 5 into a parallel beam, thereby improving the illumination range and brightness. The lamp plate 5 integrates high-power LED beads to provide sufficient illumination for outdoor shooting and tactical training. The O-ring 6 is set at the connection gap between the lamp plate 5 and the lamp cover 1 to further enhance the sealing effect and prevent moisture from seeping in and damaging the lamp plate 5.

[0026] To ensure a secure connection between the entire adjustment mechanism and the firearm, an adjustment module is installed below the main body 7. This adjustment module consists of a pressure block screw 14, a pressure block 15, a fixing nut 16, a positioning pin 17, a clamping block 27, a spring 28, a male track adjustment tooth 29, a female track adjustment tooth 30, and a movable screw 31. During installation, first, align the male rail adjustment tooth 29 and the female rail adjustment tooth 30 with the grooves of the Picatinny rail or other standard rails of the firearm. Initial positioning is achieved through the meshing of their teeth. The positioning pin 17 is then inserted into the positioning hole of the rail to ensure that there is no relative displacement between the adjustment module and the rail. Then, tighten the movable screw 31, which will drive the fixed nut 16 to move towards the clamping block 27, thereby pushing the clamping block 27 and the pressure block 15 closer together to clamp and fix the rail. The side of the clamping block 27 that contacts the rail is provided with anti-slip texture to enhance the clamping force and prevent the adjustment module from loosening due to shooting vibration. The spring 28 is set between the clamping block 27 and the adjustment module housing to provide cushioning during clamping and prevent excessive clamping from damaging the rail. At the same time, the pressure block screw 14 can adjust the pressure of the pressure block 15 to adapt to rails of different thicknesses and improve installation compatibility.

[0027] At the rear of the main body 7, a tail cover 21 is also installed. The tail cover 21 is fixed to the rear of the main body 7 by screws 22 and silicone plugs 23. The screws 22 adopt a cross-shaped or internal hexagonal structure for easy disassembly and installation. The silicone plugs 23 fill the gap between the screws 22 and the tail cover 21 to achieve a tail seal and prevent dust and moisture from entering the interior of the main body 7. Within the internal space enclosed by the main body 7 and the tail cover 21, a battery cell 18, a tail cover sealing ring 19, and a main board 20 are installed. The battery cell 18 uses a rechargeable lithium battery to provide continuous power to the laser emitter 10 and the lamp board 5. The tail cover sealing ring 19 is located at the connection end face between the main body 7 and the tail cover 21 and is made of elastic rubber. The end face is sealed by the compression of the tail cover 21, further improving the waterproof and dustproof performance. The main board 20 integrates a charging interface and control buttons. The charging interface adopts the Micro-USB or Type-C standard, which allows users to charge the battery cell 18 via a data cable. A USB rubber plug 26 is provided at the charging interface. The USB rubber plug 26 and the main board 20 are interference-fitted, which can tightly seal the interface when not charging to prevent water or dust from entering.

[0028] The control buttons on the mainboard 20 are exposed. To facilitate user operation, a button cap 25 is installed behind the tail cover 21 via a pivot 24. One end of the button cap 25 is rotatably connected to the tail cover 21 via the pivot 24, and the other end directly abuts against the control button on the mainboard. The user can press the button cap 25 to trigger the control button, thereby realizing functions such as turning the laser emitter 10 on / off and switching the lighting mode of the lamp board 5. A damping structure is provided at the pivot 24 to keep the button cap 25 at any pressing angle, avoiding accidental touch or automatic reset.

[0029] In actual use, whether for laser aiming calibration during outdoor shooting or for lighting coordination during tactical training, the entire adjustment mechanism can achieve precise adjustment and stable use through simple operation. Its simple and compact structure with few parts reduces manufacturing costs and assembly difficulty, and also reduces the risk of failure due to component wear. At the same time, the design of the pre-compression spring and precision thread can effectively resist the vibration generated during firearm firing, prevent the adjustment screw from loosening, and ensure aiming accuracy after long-term use. It completely solves the problems of low adjustment accuracy, complex structure, cumbersome operation, and poor stability in existing technologies.
