Description

Technical Field

[0001] The utility model relates to the technical field of light weapon accessories, and in particular to a light weapon sight shading device with a protective function, which reduces external light interference, enhances the durability and reliability of the sight, and makes aiming assistance more stable and accurate. Background Art

[0002] In the field of light weapons shooting, especially light weapons that use a "peephole and front sight" aiming device, such as the Type 95 squad gun family (Type 95 automatic rifle, Type 95-1 automatic rifle, etc.), the shooter needs to face the center of the peephole with his eyes during the shooting process to ensure that the front sight tip is located in the center of the peephole, thereby forming a stable and correct aiming situation (the front sight tip is in the center of the peephole which is the correct aiming situation).

[0003] This aiming method is susceptible to external light interference under strong sunlight, resulting in vignetting around the peephole. Vignetting is caused by two factors: diffuse reflection of light from the chrome plating on the gun itself and glare from the protective oil applied to the gun surface after maintenance. Vignetting prevents the shooter from seeing the entire peephole, making it impossible to confirm that the front sight is centered, significantly impacting aiming accuracy. Vignetting not only interferes with the shooter's vision, making it difficult to quickly and accurately aim at the target, but also accelerates eye fatigue and reduces shooting accuracy.

[0004] Prior art devices address this issue. Chinese Patent Publication No. CN210426261U discloses an auxiliary light-shielding device for the peephole of a Type 95 rifle. This device, through an integrated design of a mounting portion, a connecting portion, and a light-shielding portion, creates a light-shielding space, further reducing stray light and false light that enter the shooter's eyes through gaps around the peephole, thereby improving shooting accuracy. This device also features a circular mounting hole in the mounting portion, which receives a mounting screw that secures the mounting portion to the external Type 95 rifle, ensuring a stable installation. This device, which secures the mounting screw against the rifle, is not only cumbersome to install and disassemble but also causes damage to the rifle itself. It also hinders the installation of other accessories, such as optical sights. Utility Model Content

[0005] The purpose of this utility model is to provide a protective light-shielding device for the sight of a small weapon. The device can be clamped and installed using side visors, enabling quick assembly and disassembly without damaging the gun itself. The device also prevents loosening due to vibration during firing through rubber stoppers. Furthermore, the device not only eliminates the need for additional optical aiming devices, but also protects the sight on the gun body through the light-shielding space created by the visor.

[0006] The utility model provides a light weapon sight shading device with a protective function, which comprises:

[0007] The light shielding portion includes an upper light shielding cover and side light shielding plates provided on both sides of the upper light shielding cover, wherein the side light shielding plates on both sides can be clamped on the upper handguard of the light weapon;

[0008] A limit block is provided at the junction of the upper light shielding cover and the side light shielding plate, and a limit rubber is provided on the lower side of the limit block, and the limit rubber can be pressed against the top wall edge of the upper handguard when the side light shielding plate is clamped at the upper handguard;

[0009] The light blocking plate is arranged at the front end of the upper light shielding cover, and a light-transmitting window is opened on the light blocking plate.

[0010] Optionally, fluorescent rubber is provided on the rear side of each of the limit blocks.

[0011] Optionally, a half-axis rubber is provided at the bottom of the light-blocking plate, and the half-axis rubber can abut against the scope slide rail of the upper handguard.

[0012] Optionally, the side sunshade can expand outward relative to the upper sunshade cover and maintain a tendency to retract inward.

[0013] Optionally, a groove is formed at the lower portion of the side shading plate, and the groove is used to fit with the protrusion on the side wall of the upper handguard when the side shading plate is clamped on the upper handguard.

[0014] Optionally, it also includes:

[0015] The rear shading plate is arranged at the rear end of the upper shading cover.

[0016] Optionally, it also includes:

[0017] The sight adjustment window is opened on the upper part of the rear shading plate and the rear part of the upper shading cover.

[0018] Optionally, the side visors are each provided with a sight correction hole.

[0019] Optionally, the upper shading cover and the side shading plate are both made of engineering plastics.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. This utility model simplifies the installation process of the light shielding device. It can be quickly clamped and installed with a simple press, without the need for special tools. This greatly simplifies the installation process and makes disassembly more convenient, saving time and labor costs. The disassembly and assembly process does not damage the gun itself. Furthermore, the light shielding design does not occupy the standard scope rail on small arms, ensuring the normal use of standard scopes and improving the shooter's flexibility and adaptability in different shooting environments.

[0022] 2. The light-shielding space enclosed by the light-shielding device of this utility model also protects the rear sight, enhancing its protective function. The semi-axial rubber under the light-shielding plate effectively prevents wear between metal components, enhancing the stability of the device, reducing the transmission of force caused by mechanical vibration during shooting, and reducing the risk of the light shield loosening due to prolonged use. The stopper design not only enhances the stability of the device, but also prevents the peephole from being damaged or loosened due to bumps during daily training, ensuring that shooting accuracy is not affected.

[0023] 3. This utility model optimizes the light-blocking effect. The light-transmitting window on the light-blocking plate can limit the shooter's field of view, allowing the shooter to focus more closely on the forward shooting area and aiming position, effectively reducing interference from external light. This significantly reduces the generation of vignetting, especially in strong light conditions, and improves shooting accuracy. Furthermore, the fluorescent rubber on the side of the limit block facing the shooter provides a subtle fill light during nighttime shooting, helping the shooter better aim while preventing excessive brightness from exposing the shooter's position, thereby improving the accuracy and safety of nighttime shooting.

[0024] 4. This new design improves shooting accuracy and reliability. The stopper design not only enhances the stability of the device but also prevents the peephole from loosening after prolonged storage, ensuring that shooting accuracy is not affected. Furthermore, the dual protection design of the half-shaft rubber and the stopper rubber effectively reduces mechanical vibration during shooting, improving shooting stability and accuracy.

[0025] 5. Easy to operate and highly adaptable, the shading device of the utility model can be quickly installed and disassembled, and the user can complete the installation and disassembly in a short time, which is convenient for use in daily training and actual combat; the various components of the device are reasonably designed and easy to replace and maintain, which extends the service life of the device.

Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more. In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0032] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0033] In the prior art known to the inventors, existing shutters require screws to press against the gun body for installation. This not only can cause paint peeling and even rust on the gun body, but can also loosen due to vibration during firing. Once loose, the part of the gun body where the screws press against is prone to repeated wear, causing significant damage to the gun body. Furthermore, existing shutters fail to protect the rear sight, leaving it vulnerable to knocks and other physical damage. Example

[0034] This embodiment provides a light weapon sight shading device with a protective function, combined with Figure 1 The shading device includes a shading portion, which includes an upper shading cover 1 and side shading plates arranged on both sides of the upper shading cover 1. The side shading plates on both sides can be clamped on the upper handguard 13 of the light weapon.

[0035] The upper shading cover 1 is located at the top of the entire shading device and is primarily used to block light from above, reducing the interference of strong light on the shooter's vision. The side shading panels include a left shading panel 2 and a right shading panel 3. The side shading panels can block light from the sides to reduce vignetting. A rear shading panel 5 is also provided at the rear end of the upper shading cover 1 to block light from behind, further reducing the interference of vignetting.

[0036] A stopper 6 is provided at the junction of the upper light shield cover 1 and the side light shield. The stopper 6 is made of metal and can be either solid or hollow. Rubber stoppers 7 are located on the undersides of the stoppers 6 on either side. These stoppers 7 are designed to abut against the top edge of the handguard 13 when the side light shields are clamped onto it.

[0037] The stopper rubber 7 not only prevents the light shield from sliding through friction, but also prevents it from vibrating and loosening during shooting. Furthermore, to assist with nighttime shooting, fluorescent rubber is positioned on the rear side of the stopper block 6. This provides a subtle fill light during nighttime shooting to aid aiming while preventing excessive brightness that could expose the shooter's position. During installation of the light shield, when the upper light shield cover 1 is pressed downward, the stopper rubber 7 contacts the upper edge of the upper handguard 13.

[0038] The front end of the upper light shield 1 is provided with a light baffle 4. A light window 41 is defined within the light baffle 4. This window 41 limits the shooter's field of view, allowing them to focus more closely on the forward shooting area and quickly determine their aiming position. This reduces interference from external light, particularly in strong light conditions, effectively minimizing the generation of vignetting. A semi-axle rubber 42 is positioned at the bottom of the light baffle 4. This semi-axle rubber 42 is capable of contacting the upper handguard 13. In one specific embodiment, this semi-axle rubber 42 contacts the scope rail 14 on the upper handguard 13.

[0039] In addition to being able to block light in all directions to achieve the shading function, each shading component in this embodiment can also be installed without the need for specific tools such as screws, thereby not causing much damage to the gun body itself.

[0040] Specifically, the side visors in this embodiment, namely the left visor 2 and the right visor 3, are capable of expanding outward relative to the upper visor cover 1 while maintaining a tendency to retract inward. In one specific embodiment, the upper visor cover 1, the left visor 2, and the right visor 3 are all made of a material with a certain degree of elasticity, such as engineering plastic. A groove 10 is formed in the middle of each side visor, which is designed to mate with a protrusion on the side wall of the upper handguard 13 when the side visor is clamped on the upper handguard 13.

[0041] During the actual installation process, first keep the shading device horizontal, and then just fit the lower edge of its rear shading surface with the upper tail of the upper handguard 13, and then press the upper shading cover 1 downward in the vertical direction. The left shading plate 2 and the right shading plate 3 on both sides will expand outward during the pressing process until the groove 10 fits with the protrusion on the side wall of the upper handguard 13. At the same time, the limit rubber 7 can just rest against the top edge of the upper handguard 13, and the half-axis rubber 42 on the lower side of the light-blocking plate 4 just contacts the guide rail on the front side of the sight.

[0042] The light shielding device is securely mounted to the upper handguard 13, where the rear sight is located, preventing any loosening or slipping. To remove the light shielding device, simply lift the upper light shielding cover 1 to release the clamp. This embodiment's light shielding device installation method not only allows for quick assembly and disassembly, but also prevents damage to the gun itself, resulting in improved practicality.

[0043] In one specific embodiment, to ensure a smooth pressing process, the side visor is formed with a sloped surface 11 below the groove 10. During the pressing process, the sloped surface 11 contacts the upper handguard 13, gradually expanding the side visor to achieve clamping and fixation. In another specific embodiment, the side visor also has a notch 12 formed on the lower side of the inner wall. The notch 12 is capable of interlocking with the protrusion on the upper handguard 13 to further enhance the positional stability of the side visor. Example

[0044] This embodiment differs from Example 1 in that the shading device's clamping position corresponds to the rear sight position on the upper handguard 13, thereby providing both light blocking and rear sight protection. The side shading panels are each provided with a rear sight adjustment hole 8. Adjusting the rear sight is necessary in varying shooting conditions, such as weather and distance. This embodiment incorporates rear sight adjustment windows 9 in the upper shading cover 1 and rear shading panel 5, facilitating quick adjustment of the sight during combat, enabling rapid lock-on and accurate shooting.

[0045] When using the present light-shielding device, the shooter uses the rear sight and the light-transmitting window 41 on the light-blocking plate 4 to find the position of the front sight and the target, thus forming an aiming line. After the aiming is stabilized, the safety can be released and the shooting can be carried out. In different shooting environments, such as when the target distance or weather conditions change, the shooter can adjust the rear sight through the adjustment window. After selecting the appropriate rear sight, the shooting process remains the same as described above. If there is a deviation in the setting of the rear sight, there is no need to remove the present light-shielding device, but the rear sight can be adjusted through the rear sight correction hole 8 to restore the aiming accuracy.

[0046] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
