Description

Technical Field

[0001] This application relates to the field of sight bracket technology, and in particular to a sight mounting bracket and sight device. Background Technology

[0002] Infrared thermal imaging sights play a crucial role in many fields. They can form images by sensing the thermal radiation of target objects, thereby enabling target observation and aiming in low-light or even completely dark environments.

[0003] Currently, most sights on the market are directly connected to the Picatinny rail of firearms, or connected to the Picatinny rail via a shock absorber bracket. However, there is a lack of corresponding adapter brackets between the Picatinny rail and the sight, or between the Picatinny rail and the shock absorber bracket. This results in poor compatibility between the sight and the Picatinny rail, and the connection between the sight and the Picatinny rail is not stable enough. When subjected to impact, vibration, or external force, the sight is prone to loosening or displacement.

[0004] Therefore, improving the compatibility and reliability of sights on Picatinny rails is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this application is to provide a sight mounting bracket and sight device that can improve the compatibility between the sight and the Picatinny rail and ensure the connection stability between the sight and the Picatinny rail.

[0006] To achieve the above objectives, this application provides a sight mounting bracket, including an adapter bracket. The adapter bracket includes a first bracket and a second bracket, which are clamped on both sides of a guide rail. Multiple guide rods are connected to the first bracket, and the guide rods engage with the transverse grooves of the guide rail. The second bracket has through holes that slide with the guide rods, and a pull rod is connected to its center. The pull rod passes through the first bracket and is connected to a locking knob via a thread. The locking knob abuts against the outer wall of the first bracket to achieve clamping and fixation. A connecting portion extends from the upper edge of the first bracket towards the second bracket, abutting against the second bracket and connecting to an external sight.

[0007] Optionally, the distance between the lower edges of the first bracket and the second bracket gradually decreases from top to bottom to form a snap-fit ​​portion that engages with the dovetail grooves on both sides of the guide rail.

[0008] Optionally, the multiple guide rods are distributed in parallel and at equal intervals, and the lower surface of the connecting portion is provided with a limiting groove that fits against a portion of the outer wall of the guide rod.

[0009] Optionally, it also includes a vibration damping bracket fixed to the connecting part, the connecting part being provided with a positioning groove, and the vibration damping bracket being provided with a positioning post that cooperates with the positioning groove; the positioning groove includes a cylindrical groove and an oblong groove located on both sides of the connecting part, the width of the oblong groove being the same as the diameter of the cylindrical groove, and the positioning post being adapted to the cylindrical groove.

[0010] Optionally, the bottom of the vibration damping bracket abuts against the connecting part, and a fixing hole is provided on the connecting part between two adjacent guide rods. The vibration damping bracket is provided with a threaded hole that mates with the fixing hole, and the shank of the bolt passes through the fixing hole from bottom to top and is connected to the threaded hole.

[0011] Optionally, the lower surface of the connecting part is provided with a receiving groove corresponding to the fixing hole, and the head of the bolt is embedded in the receiving groove without exceeding the lower surface of the connecting part.

[0012] Optionally, the end of the pull rod is provided with an anti-loosening screw, and the locking knob is rotatably located between the outer wall of the first bracket and the head of the anti-loosening screw.

[0013] Optionally, a spring is embedded inside the locking knob, with both ends of the spring abutting against the outer wall of the first bracket and the locking knob, respectively, and the spring having an initial compression.

[0014] Optionally, the vibration damping bracket includes a lower bracket, an upper bracket, and a connecting arm connecting the two. The lower bracket is fixedly connected to the connecting part. The number of connecting arms is at least two. One end of each connecting arm is rotatably connected to the lower bracket through a first connecting shaft, and the other end is rotatably connected to the upper bracket through a second connecting shaft. The multiple connecting arms are arranged in parallel at intervals and have the same height in the vertical direction.

[0015] The upper support and / or the lower support are provided with a storage cavity on a relatively close side, and a vibration damping spring is provided in the storage cavity. One end of the vibration damping spring is connected to the lower support and the other end is connected to the upper support.

[0016] The sight is fixedly mounted on the upper bracket.

[0017] A sighting device includes a sight and a sight mounting bracket as described above.

[0018] The beneficial effects of this application are as follows: Through the double-sided clamping structure of the adapter bracket, the first and second brackets tightly clamp both sides of the guide rail. Combined with the snap-fit ​​engagement between the guide rod and the transverse groove of the guide rail, and the sliding constraint of the through hole, the stability of the sight is significantly improved. Simultaneously, the guide rod also provides a certain guiding function, facilitating the corresponding assembly of the first and second brackets. The upper edge of the first bracket extends towards the second bracket to form a connecting part, which abuts against the second bracket, ensuring that both the first and second brackets provide a certain level of support and stable support for the sight. The threaded connection design between the pull rod and the locking knob allows the adapter bracket to adapt to different guide rail sizes, and quick fixing can be achieved by adjusting the clamping force, thereby improving adaptability to various guide rail types.

[0028] 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.

It is used only for the convenience of describing this application and for simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application. Furthermore, "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] like Figure 1 and Figure 2 As shown, in this embodiment, a sight mounting bracket is provided. The mounting bracket includes an adapter bracket 2 and a vibration damping bracket 1. The adapter bracket 2 includes a first bracket 22 and a second bracket 21. The first bracket 22 and the second bracket 21 are respectively clamped on both sides of a guide rail. The guide rail in this article is a Picatinny guide rail. The first bracket 22 and the second bracket 21 are respectively in contact with the two side walls of the guide rail. At the same time, the distance between the first bracket 22 and the second bracket 21 is adjustable, thereby realizing the operation of clamping or releasing the guide rail by the adapter bracket 2. When the first bracket 22 and the second bracket 21 clamp the guide rail, the adapter bracket 2 can be positioned in the X direction.

[0032] Multiple guide rods 23 are fixedly connected to the first bracket 22. These guide rods 23 are parallel and spaced apart. When the adapter bracket 2 is installed onto the guide rail, the guide rods 23 can be locked into the transverse grooves of the guide rail, thus ensuring the positioning of the adapter bracket 2 in the Y direction. It should be noted that Picatinny rails typically have multiple parallel transverse grooves; therefore, the guide rods 23 of this application can be locked into different transverse grooves, thereby improving the stability of the adapter bracket 2 in the Y direction.

[0033] Here, the Y-axis refers to the length direction of the Picatinny rail, which is the optical axis direction of the sight; the X-axis is the width direction of the Picatinny rail, which is perpendicular to the Y-axis.

[0034] The second bracket 21 is provided with a through hole 211 that slides with the guide rod 23. One end of the guide rod 23 is fixed on the first bracket 22, and the other end of the guide rod 23 can extend into the through hole 211. Through the cooperation between the guide rod 23 and the through hole 211, the second bracket 21 can move along the axial direction of the guide rod 23 toward or away from the first bracket 22, thereby clamping or releasing the guide rail.

[0035] A pull rod 24 is fixedly connected to the middle of the second bracket 21. The other end of the pull rod 24 passes through the first bracket 22 and is connected to a locking knob 26 by a thread. The pull rod 24 is arranged parallel to the guide rod 23. During the threaded engagement between the locking knob 26 and the pull rod 24, the locking knob 26 can abut against the outer wall of the first bracket 22, thereby providing a stable support force for the pull rod 24, so that the first bracket 22 and the second bracket 21 can maintain a stable clamping state of the guide rail.

[0036] Since the pull rod 24 is located in the middle of the second bracket 21, when the pull rod 24 pulls the second bracket 21 to move towards the first bracket 22, the force on both ends of the second bracket 21 can be more even, ensuring that the second bracket 21 can slide smoothly along the guide rod 23 and ensuring the reliability of the clamping between the second bracket 21 and the first bracket 22.

[0037] In some embodiments, the first bracket 22 extends along the upper edge toward the second bracket 21 to form a connecting portion 221, which is used to connect with an external sight. The connecting portion 221 is located on the upper side of the guide rail, and the lower surface of the connecting portion 221 can abut against the upper wall of the guide rail, thereby limiting the position of the adapter bracket 2 in the Z direction, where the Z direction is the height direction of the Picatinny guide rail perpendicular to the X and Y directions.

[0038] When the first bracket 22 and the second bracket 21 are clamped on both sides of the guide rail, the connecting part 221 can also abut against the second bracket 21, thereby improving the relative stability of the first bracket 22 and the second bracket 21. In addition, a matching wedge structure or limiting structure can be provided at the end of the connecting part 221 and on the first bracket 22 to improve the degree of cooperation between the first bracket 22 and the second bracket 21 and ensure the clamping reliability of the first bracket 22 and the second bracket 21.

[0039] A positioning groove is provided on the upper surface of the connecting part 221. The vibration damping bracket 1 is provided with a positioning post that cooperates with the positioning groove. When the vibration damping bracket 1 is installed to the adapter bracket 2, the positioning post can be inserted into the positioning groove to achieve precise positioning of the two. After positioning is completed, the vibration damping bracket 1 is fixedly installed on the connecting part 221, and the sight is installed on the vibration damping bracket 1, thereby achieving a stable connection between the sight and the guide rail.

[0040] In summary, the adapter bracket 2 of this application can be adapted to a conventional universal guide rail. The guide rail is clamped by the first bracket 22 and the second bracket 21, and the adapter bracket 2 is stably mounted on the guide rail by the engaging engagement of the guide rod 23 with the transverse groove on the guide rail, providing stable support for the sight. Simultaneously, the guide rod 23 also has a guiding function, facilitating the corresponding assembly of the first bracket 22 and the second bracket 21. The sight is mounted on the adapter bracket 2 via a vibration damping bracket 1. The vibration damping bracket 1 absorbs the kinetic energy generated by impact and vibration, ensuring the accuracy of target identification and aiming. Specifically, a connecting portion 221 extends from the upper edge of the first bracket 22 towards the second bracket 21. The connecting portion 221 abuts against the second bracket 21, ensuring a certain supporting effect for both the first bracket 22 and the second bracket 21. Furthermore, a positioning groove is provided on the upper surface of the connecting portion 221. The vibration damping bracket 1 can engage with the positioning groove via a positioning pin, ensuring the installation accuracy of the vibration damping bracket 1. After positioning, the vibration damping bracket 1 is fixed to the adapter bracket 2, allowing the sight to be stably and reliably mounted on the guide rail.

[0041] In some embodiments, the distance between the lower edges of the first bracket 22 and the second bracket 21 gradually decreases from top to bottom, thereby forming a locking part that engages with the dovetail grooves on both sides of the guide rail. Through the engagement of the locking part with the dovetail groove and the abutment of the connecting part 221 with the upper wall of the guide rail, precise positioning in the Z direction can be achieved, ensuring the reliability of the sight's installation on the guide rail.

[0042] When installing the adapter bracket 2, firstly, place the first bracket 22 carrying the guide rod 23 on one side of the guide rail. The guide rod 23 is located in the transverse groove of the guide rail, and the connecting part 221 contacts the upper wall of the guide rail. The snap-fit ​​part of the lower edge of the first bracket 22 corresponds to the dovetail groove on one side of the guide rail. Place the second bracket 21 on the other side of the guide rail. The guide rod 23 is inserted into the through hole 211 of the second bracket 21, and the pull rod 24 is inserted into the first bracket 22. The snap-fit ​​part of the lower edge of the second bracket 21 corresponds to the dovetail groove on the other side of the guide rail. Turn the locking knob 26 to make the second bracket 21 gradually move towards the first bracket 22 under the action of the pull rod 24. The second bracket 21 and the first bracket 22 cooperate to gradually clamp the guide rail, and the snap-fit ​​part snaps into the dovetail groove.

[0043] In some embodiments, to adapt to the current arrangement of transverse grooves on guide rails, the plurality of guide rods 23 in this application are parallel and equally spaced, and a limiting groove 222 that fits against a portion of the outer wall of the guide rod 23 is provided on the lower surface of the connecting portion 221. Please refer to... Figure 2 The cooperation between the limiting groove 222 and the guide rod 23 can improve the stability of the guide rod 23; of course, the lower part of the outer wall of the guide rod 23 is exposed to ensure that it can be locked into the transverse groove.

[0044] Please refer to Figure 3The positioning groove includes a cylindrical groove 225 and an oblong groove 226 located on both sides of the connecting part 221. The width of the oblong groove 226 is the same as the diameter of the cylindrical groove 225, and the positioning post is adapted to the cylindrical groove 225. The length of the oblong groove 226 is greater than the diameter of the cylindrical groove 225. During the engagement of the positioning post and the positioning groove, the two positioning posts can be inserted into the cylindrical groove 225 and the oblong groove 226 respectively. Since the length of the oblong groove 226 is greater than the diameter of the positioning post, the oblong groove 226 can provide a certain margin for one of the positioning posts, avoiding the situation where the two positioning posts cannot be accurately inserted into the positioning groove due to machining errors, assembly errors, etc.

[0045] To improve the connection reliability between the vibration damping bracket 1 and the adapter bracket 2, when the vibration damping bracket 1 is installed on the adapter bracket 2, the bottom of the vibration damping bracket 1 can abut against the upper surface of the connecting part 221. A fixing hole 223 is provided on the connecting part 221 between two adjacent guide rods 23. The vibration damping bracket 1 is provided with a threaded hole that matches the fixing hole 223. The shank of the bolt 3 passes through the fixing hole 223 from bottom to top and is connected to the threaded hole, thereby realizing the fixed connection between the vibration damping bracket 1 and the adapter bracket 2.

[0046] To prevent the head of bolt 3 from affecting the stable contact between the connecting part 221 and the guide rail, a receiving groove 224 corresponding to the fixing hole 223 can be provided on the lower surface of the connecting part 221. Please refer to... Figure 2 After the bolt 3 is locked in the vibration damping bracket 1 and the adapter bracket 2, the head of the bolt 3 can be embedded in the receiving groove 224, and the head of the bolt 3 does not extend beyond the lower surface of the connecting part 221.

[0047] It should be noted that, in order to facilitate the connection of the vibration damping bracket 1 and the adapter bracket 2 by bolt 3, the vibration damping bracket 1 can be locked onto the adapter bracket 2 by bolt 3 before the adapter bracket 2 is installed on the guide rail, and then the subsequent operations can be carried out.

[0048] Please refer to Figure 2 An anti-loosening screw 27 is provided at the end of the pull rod 24. The locking knob 26 is rotatably located between the outer wall of the first bracket 22 and the anti-loosening screw 27, which can prevent the locking knob 26 from accidentally falling off during the turning process. Of course, the anti-loosening screw 27 is detachably connected to the pull rod 24 and can be removed when necessary to take out the locking knob 26.

[0049] A spring 25 is embedded inside the locking knob 26. The two ends of the spring 25 abut against the outer wall of the first bracket 22 and the locking knob 26 respectively. The spring 25 has an initial compression amount, which can provide a certain initial tension force for the locking knob 26 and the pull rod 24, ensuring the clamping effect of the first bracket 22 and the second bracket 21 when clamping the guide rail.

[0050] Please refer to Figure 4 and Figure 5The vibration damping bracket 1 of this application includes a lower bracket 12, an upper bracket 11, and a connecting arm 15 connecting the two. The lower bracket 12 is fixedly connected to the connecting part 221. There are at least two connecting arms 15. One end of each connecting arm 15 is rotatably connected to the lower bracket 12 through a first connecting shaft 13, and the other end is rotatably connected to the upper bracket 11 through a second connecting shaft 14. Multiple connecting arms 15 are arranged in parallel at intervals and have the same height in the vertical direction, thereby forming a parallelogram movable connection structure. A storage cavity 17 is provided on the relatively close side of the lower bracket 12 and / or the upper bracket 11. A vibration damping spring 16 is provided in the storage cavity 17. One end of the vibration damping spring 16 is connected to the lower bracket 12 and the other end is connected to the upper bracket 11. The sight is fixedly installed on the upper bracket 11.

[0051] When subjected to an impact force, the guide rail drives the adapter bracket 2 to move, and the adapter bracket 2 drives the lower bracket 12 to move. At this time, the lower bracket 12 compresses the damping spring 16 to absorb part of the impact kinetic energy. The connecting arm 15 drives the upper bracket 11 to move through the second connecting shaft 14. The upper bracket 11 moves in the opposite direction and upward relative to the lower bracket 12. After the impact disappears, the damping spring 16 recovers its elastic potential energy, causing the upper bracket 11 to return to its original position.

[0052] If the storage cavity 17 is located on the upper support 11, a stop block can be installed on the lower support 12. The stop block extends into the storage cavity 17. One end of the damping spring 16 abuts against the cavity wall of the storage cavity 17, and the other end abuts against the stop block, thereby achieving the connection of both ends of the damping spring 16 to the upper support 11 and the lower support 12 respectively.

[0053] This application also provides a sight device, which includes a sight and a sight mounting bracket as described above.

[0054] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0055] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
