Description

Technical Field

[0001] This utility model relates to the field of firearm sight calibration equipment technology, and in particular to a high coaxiality light weapon connection device. Background Technology

[0002] Firearms are the standard weapons among small arms, primarily used to kill enemy personnel. These weapons are primarily aimed using rifle sights or scopes. The accuracy of the aiming device affects the accuracy of the small arms hitting the target. Because rifle sights or scopes use mechanical structures mounted on small arms, the impact force generated by firing can cause the sights to shift from zero, impairing their accuracy in subsequent uses. Furthermore, modern soldiers are equipped with small arms for different purposes, each with different sights, and due to varying combat environments, they also need to improve their hit rate even at night.

[0003] The existing multi-stage tritium sight calibration scope (publication number: CN204612592U) has at least the following drawbacks: While the device can be adapted to firearms of different calibers through its insert and expansion shaft configuration, small arms range from assault rifles with a minimum caliber of 5.45mm to sniper rifles with a large caliber of 12.7mm. Relying on a fixed-caliber expansion shaft to fix the barrel to different calibers makes it difficult to guarantee reliability and stability when fixing to larger caliber barrels. Furthermore, a large caliber difference leads to excessive gaps between the expansion shaft and the barrel, making it difficult to ensure the coaxial stability of the barrel and the expansion shaft. Therefore, this utility model is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high coaxiality light weapon connection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high coaxiality light weapon connection device includes a zero-position calibration instrument. The top surface of the zero-position calibration instrument is provided with a connection component for connecting the firearm. The connection component includes an adjusting vertical plate installed on the top surface of the zero-position calibration instrument. A guide rod is installed on the adjusting vertical plate. The guide rod includes a fixed seat, an outer guide rod, and an inner guide rod. A mounting hole is opened on one side of the adjusting vertical plate. The fixed seat is movably inserted into the mounting hole. A mounting nut is threaded to the rear end of the outer wall of the fixed seat. The outer guide rod is fixed inside the fixed seat. The inner guide rod is slidably inserted inside the outer guide rod. The outer guide rod has a structure that is thinner at the front end and thicker at the rear end. A conical surface is provided in the middle of the outer wall of the outer guide rod at the junction of the thin and thick sections.

[0007] As a further embodiment of this utility model, the front end of the outer guide rod is provided with several longitudinally divided slits, which cut the tube body into multiple elastic segments. The front end of the inner guide rod is provided with a cone, which extends out of the front end of the outer guide rod. The elastic segments abut against the inclined surface of the outer wall of the cone. The rear end of the inner guide rod is threaded with an adjusting nut, and the front side of the adjusting nut abuts against the rear end of the outer guide rod.

[0008] As a further embodiment of this utility model, the mounting holes are a plurality of holes, which are arranged in a linear array along the length of the adjusting vertical plate, and the fixing seat is inserted into any mounting hole.

[0009] As a further embodiment of this utility model, a limiting port is provided on the front side of the fixing base, and limiting strips are fixed on one side of the mounting hole on the adjusting vertical plate, with the limiting strips and the corresponding limiting ports having an interference fit.

[0010] As a further embodiment of this utility model, the top end of the limiting strip is a triangular prism structure.

[0011] As a further embodiment of this utility model, mounting bolts are movably inserted at the four corners of the top surface of the adjusting vertical plate, and the mounting bolts are threadedly connected to the top surface of the zero-position calibration instrument.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By setting up an adjusting vertical plate, mounting nuts, and a fixing base, the guide rod is installed on the zero-position calibration instrument. The guide rod is inserted into the weapon firing tube, and the target plate is observed through the zero-position calibration instrument. When changing to weapons of different calibers, only the guide rod needs to be replaced, ensuring perfect compatibility between the guide rod and weapons of different calibers. The conical surface set in the middle of the outer wall of the guide rod allows the guide rod and the gun barrel to be connected in a conical shape, ensuring the stability of the coaxiality of the guide rod and the gun barrel and improving calibration accuracy. The front end of the guide rod is equipped with an elastic segment, which can be expanded by the cone head and tightly adhere to the inner wall of the gun barrel to fix the guide rod to the gun barrel, eliminating the gap between the guide rod and the gun barrel and ensuring the stability and reliability of their fixation. The adjusting vertical plate is also installed with mounting bolts for detachable installation with the zero-position calibration instrument, which facilitates the removal of the guide rod and adjusting vertical plate and installation on the corresponding model of zero-position calibration instrument when different light weapons need to be calibrated, increasing the applicability of the device.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figures 1-4As shown, a high coaxiality light weapon connection device includes a zero-position calibration instrument 1. The top surface of the zero-position calibration instrument 1 is provided with a connecting component for connecting a firearm. The zero-position calibration instrument 1 can include various models, such as a firearm zero-position calibration instrument, a high-precision sniper scope zero-position calibration instrument, and a 4.35mm grenade launcher scope zero-position calibration instrument, etc., and can be replaced according to the firearm sight to be calibrated. The universal scope calibration instrument connecting component includes an adjusting vertical plate 2 installed on the top surface of the zero-position calibration instrument 1. A guide rod is installed on the adjusting vertical plate 2, and the guide rod includes a fixed... The fixed seat 202, the outer guide rod 204, and the inner guide rod 205 are provided. An installation hole 201 is provided on one side of the adjusting vertical plate 2. The fixed seat 202 is movably inserted into the installation hole 201. An installation nut 203 is threadedly connected to the rear end of the outer wall of the fixed seat 202. The outer guide rod 204 is fixed inside the fixed seat 202. The inner guide rod 205 is slidably inserted inside the outer guide rod 204. The outer guide rod 204 has a structure that is thin at the front end and thick at the rear end. A conical surface is provided in the middle of the outer wall of the outer guide rod 204 at the junction of the thin and thick parts.

[0023] like Figures 2-4 As shown, in this embodiment, the front end of the outer guide rod 204 is longitudinally provided with several dividing slits 206, which cut the tube body into multiple elastic segments 207. The front end of the inner guide rod 205 is provided with a cone 208, which extends out of the front end of the outer guide rod 204. The elastic segments 207 abut against the inclined surface of the outer wall of the cone 208. The rear end of the inner guide rod 205 is threaded with an adjusting nut 209, the front side of which abuts against the rear end of the outer guide rod 204. By inserting the fixing seat 202 into the mounting hole 201 from the front side of the adjusting vertical plate 2, and then threading the mounting nut 203 from the rear side of the adjusting vertical plate 2 to the fixing seat 202, the fixing seat 202 is fixed to the adjusting vertical plate 2. Next, the guide rod 204 is inserted into the barrel of the firearm to be calibrated, so that the conical surface of the guide rod 204 mates with the muzzle, ensuring the straightness and coaxiality of the barrel and the guide rod. Then, the adjusting nut 209 is rotated, and the front side of the adjusting nut 209 abuts against the guide rod 204 and pulls the guide rod 205 backward, so that the cone 208 of the guide rod 205 abuts against the elastic plate 207, causing the elastic plate 207 to expand and deform and fit tightly against the inner wall of the barrel, thereby fixing the guide rod 204 and the barrel tightly, eliminating the gap between the guide rod 204 and the barrel, and ensuring the stability and reliability of their fixation. Then, the zero-position calibration instrument 1 can be started to perform functional checks and performance tests on the firearm sights, realizing rapid firearm calibration.

[0024] like Figures 2-4As shown, in this embodiment, there are several mounting holes 201, which are arranged in a linear array along the length of the adjusting vertical plate 2. The fixing seat 202 is inserted into any mounting hole 201. By setting several mounting holes 201, the fixing seat 202 can be inserted into the corresponding mounting hole 201 from the front side of the adjusting vertical plate 2 according to the position of the sight, ensuring that the zero-position calibration instrument 1 is at the same height as the sight, and increasing the applicability of the device.

[0025] like Figures 2-4 As shown in this embodiment, a limiting port 3 is provided on the front side of the fixed base 202, and a limiting strip 301 is fixed on one side of the mounting hole 201 on the adjusting vertical plate 2. The limiting strip 301 and the corresponding limiting port 3 are internally interference fit. By setting the limiting port 3 and the limiting strip 301, the fixed base 202 can be prevented from rotating relative to the adjusting vertical plate 2 after the fixed base 202 and the adjusting vertical plate 2 are installed, so as to avoid affecting the calibration of the sight.

[0026] like Figures 2-4 As shown, in this embodiment, the top end of the limiting strip 301 is a triangular prism structure. By setting the top end of the limiting strip 301 to a triangular prism structure, the limiting strip 301 can be more easily inserted into the interior of the limiting port 3.

[0027] like Figures 2-4 As shown, in this embodiment, mounting bolts 4 are movably inserted at the four corners of the top surface of the adjusting vertical plate 2. The mounting bolts 4 are threadedly connected to the top surface of the zero-position calibration instrument 1. By setting the mounting bolts 4, the adjusting vertical plate 2 and the zero-position calibration instrument 1 can be detachably installed, which facilitates the disassembly of the guide rod and the adjusting vertical plate 2 and their installation on the corresponding model of the zero-position calibration instrument 1 when different light weapons need to be calibrated, thereby increasing the applicability of the device.

[0028] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: In use, when the firearm needs to be zeroed, the fixing seat 202 is inserted into the corresponding mounting hole 201 from the front side of the adjusting vertical plate 2 according to the position of the sight, ensuring that the zeroing instrument 1 is at the same height as the sight. Then, the mounting nut 203 is threadedly connected to the fixing seat 202 from the rear side of the adjusting vertical plate 2, so that the fixing seat 202 is fixed on the adjusting vertical plate 2. At this time, the corresponding limiting strip 301 is connected to the internal limit port 3 with an interference fit, which plays a role in limiting and preventing rotation of the fixing seat 202. Then, the adjusting vertical plate 2 is detachably installed with the zeroing instrument 1 using the mounting bolt 4, thereby installing the guide rod together with the zeroing instrument 1. At this point, the outer guide rod 204 is inserted into the barrel of the firearm to be calibrated, so that the conical surface on the outer guide rod 204 mates with the muzzle, ensuring the straightness and coaxiality of the barrel and the guide rod. Then, the adjusting nut 209 is rotated, and the front side of the adjusting nut 209 abuts against the outer guide rod 204 and pulls the inner guide rod 205 backward, so that the cone 208 of the inner guide rod 205 abuts against the elastic plate 207, causing the elastic plate 207 to expand and deform and tightly abut against the inner wall of the barrel, thereby fixing the outer guide rod 204 and the barrel tightly, eliminating the gap between the outer guide rod 204 and the barrel, and ensuring the stability and reliability of their fixation. Then, the zero-position calibration instrument 1 can be started to perform functional checks and performance tests on the firearm sights, realizing rapid firearm calibration.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
