Description

Technical Field

[0001] This application belongs to the technical field of firearm maintenance tools, and specifically relates to a firearm sight adjustment and maintenance tool and method. Background Technology

[0002] Modern military firearms use mechanical sights (such as front sights and rear sights) that require frequent adjustments to ensure shooting accuracy. Currently, the traditional adjustment tools provided with the firearms usually consist of multiple separate parts that must be assembled on-site before use. This is not only cumbersome to operate and prone to loss in emergency situations in the field, but also means that the accessories for each type of firearm are independent and cannot be used interchangeably across different models.

[0003] At the same time, the existing maintenance accessories are too limited in purpose. When soldiers perform routine weapon disassembly and assembly, peep hole cleaning, or rapid magazine loading, they often need to carry a variety of different special tools. This not only significantly increases the burden on individual soldiers, but also greatly reduces the efficiency of logistical support in field operations.

[0004] In addition, dust and grease in harsh outdoor environments can easily accumulate and fill the adjustment slots of the sight. Existing adjustment tools lack effective self-cleaning or dirt-absorbing and draining structures. During repeated adjustments, the precision front sight is easily damaged by impurities, or even jammed by debris, preventing the tool from properly coupling with the sight components and causing adjustment failure. Summary of the Invention

[0005] The purpose of this application is to provide a tool and method for adjusting and maintaining firearm sights. This addresses the technical problems mentioned in the background art, such as the firearm sight adjustment tools having limited functionality, requiring on-site assembly, poor versatility, and lacking a drainage structure.

[0006] To achieve the above objectives, this application adopts the following technical solution: In a first aspect, a firearm sight adjustment and maintenance tool is provided, comprising a first functional part, a second functional part, and a handgrip. The end of the first functional part is provided with a first adjustment structure for engaging a first iron sight of a firearm.

[0007] The end of the second functional unit is equipped with a second adjustment structure for docking with the second iron sight of the firearm. The handgrip serves as a torque transmission rod and connects to both the first and second functional units.

[0008] One end of the handle is provided with a bit mounting hole. The cross-section of the bit mounting hole is non-circular, which is used to limit the fit with the outer circumferential surface of a standard tool bit.

[0009] An axial limiting component is provided in the bit mounting hole to limit the axial movement of the standard tool bit.

[0010] In one possible implementation, the first functional part is a front sight adjustment part, and the first adjustment structure includes a front sight hole disposed on the end face of the front sight adjustment part and at least two front sight slots disposed on the inner wall of the front sight hole. The front sight slots are used to lock the flat part of the gun front sight to transmit torque.

[0011] The second functional part is the scale adjustment part. The second adjustment structure is an arc-shaped plate structure. The arc edge of the arc-shaped plate structure is used to fit into the slot of the firearm scale adjustment screw and adapt to it. The sight adjustment part is also provided with a drain hole, which is a through hole that connects the inner cavity of the sight hole to the outside.

[0012] In one possible implementation, the bit mounting hole is a screwdriver bit through hole, and a recessed stop hole is provided on part of the inner wall of the screwdriver bit through hole. The diameter of the stop hole is smaller than the inscribed circle diameter of the screwdriver bit through hole.

[0013] In one possible implementation, the axial limiting component is a magnetic adsorption element or an elastic clamping ring embedded in the bit mounting hole.

[0014] In one possible implementation, a push rod is provided at the end of the hand grip away from the aiming adjustment part, and the push rod is a protruding rod-like object.

[0015] In one possible implementation, the tool is also provided with a loading hook, which is an outwardly extending hook-shaped part used to hook onto the fixing hole of the pistol magazine follower.

[0016] In one possible implementation, the tool also has a hole through which a rope is attached.

[0017] In one possible implementation, the front sight adjustment section and the scale adjustment section are arranged collinearly, and the handle extends outward perpendicular to the collinear axis, with the three parts connected as a single unit in a T-shaped configuration.

[0018] Secondly, this application also provides a method for adjusting and maintaining a firearm sight, using the aforementioned firearm sight adjustment and maintenance tool, including the following steps: The first adjustment structure of the first functional unit is connected to the first iron sight of the firearm, or the second adjustment structure of the second functional unit is connected to the second iron sight of the firearm, or the first adjustment structure is connected to the first iron sight and the second adjustment structure is connected to the second iron sight at the same time. By applying a torsional torque through the handle, the first or second adjustment mechanism is driven to rotate, thereby adjusting the position of the first or second mechanical sight; Alternatively, a standard tool bit can be inserted into the bit mounting hole, so that the outer circumference of the standard tool bit is matched with the non-circular inner wall of the bit mounting hole, and the standard tool bit is axially limited by the axial limiting component. Force is then applied to the handle to disassemble and assemble the firearm using the standard tool bit.

[0019] In one possible implementation, the above method further includes at least one of the following steps: When it is necessary to disassemble a firearm, align the push rod with the retaining pin of the firearm and apply a pushing force to push the retaining pin out of the firearm. When it is necessary to clean the sight hole, insert the push rod into the sight hole of the firearm and move it back and forth to clean the debris in the sight hole; When it is necessary to load a pistol magazine, hook the loading hook into the fixing hole of the magazine follower, use the tool as a lever to press the follower and press the ammunition into the magazine; When it is necessary to prevent tools from falling, pass the safety rope through the lanyard hole and secure the tool to the firearm or the user; When impurities accumulate inside the front sight, the dust or grease inside the front sight is discharged through the drain hole.

[0020] Compared with the prior art, this application has the following beneficial effects: The provided tool is a gun sight adjustment and maintenance tool. By setting up a first functional part, a second functional part, and a hand handle, the sight adjustment function and the bit installation function are integrated into a single integrated structure. It can be used directly without on-site assembly, which effectively solves the problems of traditional tools that require on-site assembly, are cumbersome to operate, and are easy to lose. At the same time, the bit installation hole is compatible with standard tool bits, which expands the applicability of the tool.

[0021] In one possible implementation, by specifying the first functional part as a front sight adjustment part and providing a front sight hole and at least one front sight slot, the flat part of the firearm's front sight can be reliably locked to transmit torque for front sight adjustment; by specifying the second functional part as a scale adjustment part and providing an arc-shaped plate structure, the scale can be well locked into the slot of the firearm's scale adjustment screw for scale adjustment, thereby enabling a single tool to simultaneously provide adjustment functions for both the front sight and the scale, improving the tool's practicality and versatility.

[0022] In one possible implementation, by providing an inwardly recessed stop hole on the inner wall of a portion of the screwdriver bit's through hole, and the diameter of the stop hole being smaller than the inscribed circle diameter of the screwdriver bit's through hole, the user can press their fingers against the stop hole when holding the handle and applying force, effectively preventing the hand from slipping during force application and improving the safety and reliability of operation.

[0023] In one possible implementation, by setting the axial limiting component as a magnetic adsorption element or elastic clamping ring embedded in the bit mounting hole, the inserted standard tool bit can be reliably axially limited, preventing the bit from accidentally falling off during use and ensuring the safety of disassembly and assembly operations.

[0024] In one possible implementation, by setting a push rod at the end of the handgrip away from the front sight adjustment part, and the push rod being a protruding rod-like object, the tool can simultaneously possess the functions of firearm disassembly (pushing out the fixing pin) and scope peep hole cleaning, further enriching the tool's functional integration and reducing the types and number of tools that soldiers need to carry.

[0025] In one possible implementation, by setting an outwardly extending hook-shaped part as a loading hook, it can hook onto the fixing hole of the pistol magazine follower, and use the tool itself as a handle to press the follower to achieve rapid loading, which effectively solves the problem of laborious and slow pistol magazine loading and improves loading efficiency under field conditions.

[0026] In one possible implementation, by creating a lanyard hole, the user can pass a safety rope or anti-loss rope through the lanyard hole and secure the tool to the firearm or the user, effectively preventing the tool from being dropped or lost during field operations and improving the safety of carrying the tool.

[0027] In one possible implementation, the sight adjustment part and the scale adjustment part are arranged collinearly, and the handle extends outward perpendicular to the collinear axis. The three parts are connected as a whole in a T-shaped configuration, making the overall structure of the tool compact and the force distribution reasonable. When the user holds the handle and applies force, the torque transmission efficiency is high, and the operation is more labor-saving and precise.

[0028] A method for adjusting and maintaining firearm sights is provided. By using the aforementioned tools and following the steps of adjusting the sight by connecting and adjusting the structure, applying torsional torque to adjust the sight, or installing a screwdriver bit for disassembly and assembly, this method enables efficient adjustment of various firearm sights and disassembly and maintenance of firearms. The method is clear, easy to operate, and effectively improves the efficiency of firearm maintenance in the field.

[0029] In one possible implementation, by further defining multiple optional operation steps such as the push rod ejecting the fixing pin, the push rod cleaning the sight hole, the loading hook assisting in loading, the lanyard hole for threading the lanyard to prevent loss, and the drain hole for removing impurities, the tool's usage method covers a variety of scenarios for daily firearm maintenance. Users can flexibly select the corresponding operation steps according to actual needs, further improving the tool's practicality and applicability. Attached Figure Description

[0037] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] like Figure 1 and Figure 2 As shown, this application provides a firearm sight adjustment and maintenance tool. The tool is an integrated structure comprising a first functional part, a second functional part, and a handle 6. The end of the first functional part is equipped with a first adjustment structure for engaging a first iron sight of the firearm, and the end of the second functional part is equipped with a second adjustment structure for engaging a second iron sight of the firearm. The handle 6 serves as a torque transmission rod and connects to the first and second functional parts. One end of the handle 6 has a bit mounting hole with a non-circular cross-section for limiting engagement with the outer circumferential surface of a standard tool bit. An axial limiting component is provided within the bit mounting hole for axially limiting the standard tool bit.

[0039] In this embodiment, the tool is a one-piece structure machined in one piece, made entirely of stainless steel or titanium alloy, which has the advantages of high strength, corrosion resistance, and light weight. Its compact size makes it easy to carry; it can be placed in the existing accessory container of the firearm or secured to a firearm sling or safety rope via a lanyard.

[0040] The first functional part is the front sight adjustment part 1. A front sight hole 2 is provided on the end face of the front sight adjustment part 1. The front sight hole 2 is a concave blind hole used to accommodate the front sight tip of the firearm. At least two front sight slots 3 are provided on the inner wall of the front sight hole 2. The front sight slots 3 are used to hold the flat part of the firearm's front sight to transmit torque. The depth of the front sight hole 2 is greater than the height of the front sight tip of the firearm to be adjusted, to prevent the front sight tip from colliding with the bottom of the front sight hole 2 and being damaged during adjustment. A sludge drain hole 4 is also provided on the front sight adjustment part 1. The sludge drain hole 4 is a through hole connecting the inner cavity of the front sight hole 2 to the outside, used to discharge dust, oil, and other impurities accumulated inside the front sight hole 2.

[0041] The second functional part is the scale adjustment section 5. The scale adjustment section 5 is an arc-shaped plate structure. The arc edge of the arc-shaped plate structure is used to engage and fit into the slot of the firearm scale adjustment screw. In use, the arc edge of the scale adjustment section 5 is engaged into the slot of the scale adjustment screw, and the hand handle 6 is rotated to drive the scale adjustment screw to adjust the scale position.

[0042] The handle 6 is a rod-shaped extension that serves as a torque transmission rod for applying force during operation. One end of the handle 6 is connected to the front sight adjustment part 1 and the scale adjustment part 5. In this embodiment, the front sight adjustment part 1 and the scale adjustment part 5 are arranged collinearly, and the handle 6 extends outward perpendicular to this collinear axis, with the three parts connected as a single unit in a T-shape. This configuration results in high torque transmission efficiency when the user applies force by gripping the handle 6, making operation more effortless and precise.

[0043] The screwdriver bit mounting hole is a through-hole 7 for screwdriver bits. The cross-section of the through-hole 7 is non-circular (e.g., hexagonal) to allow for a limiting fit with the outer circumferential surface of a standard 1 / 4-inch screwdriver bit. A recessed stop hole 8 is provided on a portion of the inner wall of the through-hole 7; the diameter of the stop hole 8 is smaller than the inscribed circle diameter of the through-hole 7. In use, a standard screwdriver bit is inserted into the through-hole 7, and the outer circumferential surface of the bit fits against the non-circular inner wall of the hole, preventing relative rotation of the bit during twisting. When the user grips the handle 6 and applies force, their fingers can press against the stop hole 8, effectively preventing hand slippage.

[0044] In one possible implementation, the axial limiting component is a magnetic adsorption element 9 or an elastic clamping ring embedded in the bit mounting hole. For example... Figure 1 As shown, this embodiment employs a magnetic adsorption component 9, which is embedded inside the screwdriver bit through-hole 7 to magnetically attract the inserted standard tool bit, preventing the bit from accidentally falling off during use. In another embodiment, the axial limiting component can also be an elastic clamping ring, which uses elastic clamping force to axially limit the bit.

[0045] A push rod 10 is provided at the end of the handgrip 6 away from the front sight adjustment part 1. The push rod 10 is a protruding rod-like object with a cross-sectional diameter smaller than that of the handgrip 6. The push rod 10 can be used to eject the fixing pins of the firearm (such as the firing pin pin, trigger pin, etc.), thereby disassembling the firearm. At the same time, the slender structure of the push rod 10 can also extend into the sight hole of the firearm to clean debris inside and around the sight hole.

[0046] The tool is also equipped with a loading hook 11. The loading hook 11 is an outwardly extending hook-shaped part, located at the junction of the front sight adjustment part 1 and the handle 6, or at the junction of the scale adjustment part 5 and the handle 6. The loading hook 11 is used to hook the fixing hole of the pistol magazine follower. When in use, the tool itself acts as a lever to press the follower, quickly pressing the ammunition into the magazine, achieving a labor-saving and fast loading operation.

[0047] The tool also has a lanyard hole 12. The lanyard hole 12 can be located on the handle 6 or the sight adjustment part 1. When in use, a safety rope or anti-loss rope is passed through the lanyard hole 12 and the tool is secured to the firearm or the user, which can effectively prevent the tool from being dropped or lost during field operations.

[0048] This application also provides a method for adjusting and maintaining a firearm sight, using the aforementioned firearm sight adjustment and maintenance tool. The method includes the following steps: When adjusting the iron sights of a firearm, the user holds the handle 6 and aligns the first adjustment mechanism of the first functional unit with the first iron sight of the firearm, or aligns the second adjustment mechanism of the second functional unit with the second iron sight of the firearm, or simultaneously aligns the first adjustment mechanism with the first iron sight and the second adjustment mechanism with the second iron sight. Then, a torsional torque is applied through the handle 6 to drive the first or second adjustment mechanism to rotate, thereby adjusting the position of the first or second iron sight.

[0049] Specifically, when adjusting the front sight, align the front sight adjustment part 1 with the front sight of the firearm, so that the front sight tip is accommodated in the front sight hole 2, and the front sight slot 3 locks the flat part of the front sight. Then, rotate the handle 6, which drives the front sight to rotate through the front sight slot 3, thereby adjusting the front sight position. When adjusting the scale, insert the curved edge of the scale adjustment part 5 into the slot of the scale adjustment screw, and rotate the handle 6, which drives the scale adjustment screw to rotate through the scale adjustment part 5, thereby adjusting the scale position.

[0050] When the screwdriver function is needed, insert the standard tool bit into the bit mounting hole, ensuring that the outer circumference of the standard tool bit engages with the non-circular inner wall of the mounting hole, and axially limit the standard tool bit using the axial limiting component. Then, grip the handle 6 and apply force to perform disassembly and assembly operations on the firearm using the standard tool bit, such as disassembling and reassembling standard parts like bolts and screws on the firearm.

[0051] The method also includes one or more of the following optional steps: When it is necessary to disassemble the firearm, align the push rod 10 with the firearm's retaining pin (such as firing pin pin, trigger pin, etc.) and apply a pushing force to push the retaining pin out of the firearm, thereby disassembling the firearm.

[0052] When it is necessary to clean the sight hole, insert the top rod 10 into the sight hole of the firearm and move it back and forth to clean the debris inside and around the sight hole to ensure that the sight hole is unobstructed.

[0053] When it is necessary to load the pistol magazine, hook the loading hook 11 into the fixing hole of the magazine follower plate, use the tool as a lever to press the follower plate, and press the ammunition into the magazine in sequence to achieve rapid loading.

[0054] When it is necessary to prevent the tool from falling, pass the safety rope through the lanyard hole 12 and secure the tool to the firearm or the user.

[0055] When impurities accumulate inside the front sight hole 2, the dust or grease inside the front sight hole 2 is discharged out through the drain hole 4 to keep the inside of the front sight hole 2 clean and ensure that the front sight tip can be smoothly accommodated in the front sight hole 2.

[0056] In this embodiment, all functional components of the tool—the sight adjustment part 1, the scale adjustment part 5, the handle part 6, the push rod 10, the loading hook 11, and the lanyard hole 12—are fixedly mounted on the tool body and their relative positions are fixed, forming an integrated structure. The entire tool is machined from a single blank (e.g., CNC machining or other precision machining and manufacturing processes), and can be used directly without any assembly or unfolding operations.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them; although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions for some or all of the technical features, do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
