Description

Technical Field

[0001] This application belongs to the field of firearm bipod technology, specifically a guide rail clamp and a firearm bipod. Background Technology

[0002] A gun bipod is a device that provides additional support for a firearm, and it is mainly divided into bipods and monopods. Bipods are widely used on long-barreled firearms such as machine guns, automatic rifles, assault rifles, and sniper rifles. Their core function is to significantly improve shooting stability and accuracy by increasing the number of points of contact with the ground.

[0003] The mounting method for modern rifle bipods has undergone a significant evolution, largely thanks to the widespread adoption of Picatinny rails. Picatinny rails, nicknamed "fishbone" or simply "Picatinny rails," are a standardized accessory mounting platform. They appear as a metal rail with evenly spaced transverse grooves. These precisely machined protrusions and notches ensure consistent positioning and secure locking of various accessories. Modern firearms use far more than just Picatinny rails; it is merely one of the most representative standards. To adapt to different needs, reduce weight, or simplify production, various distinctive rail systems have emerged. Furthermore, to accommodate these diverse rail systems and meet the shooter's need for rapid weapon configuration changes in different scenarios, bipods have also needed to evolve towards modularity. Utility Model Content

[0004] The purpose of this application is to provide a rail clamp and a gun bipod. The rail clamp adopts a modular design, which not only facilitates assembly but also allows for quick replacement of different rail clamping systems while retaining angular functionality. Furthermore, this application also provides a gun bipod equipped with this rail clamp.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A guide rail clamp includes a base, a movable component, a fixed component, and a clamping assembly. The movable component is rotatably connected to the base, and its rotation axis is horizontally arranged. The movable component has a mounting hole, the axis of which is perpendicular to the rotation axis of the movable component. The clamping assembly is used to clamp an external firearm guide rail. The bottom of the clamping assembly has a mounting shaft that matches the mounting hole. The clamping assembly is inserted into the mounting hole via the mounting shaft, and the mounting shaft can rotate within the mounting hole. The fixed component is connected to the movable component and can simultaneously lock the movable component and the mounting shaft.

[0007] In the aforementioned guide rail clamping seat, the movable component includes a connecting shaft and a movable block. The seat body has a placement part, the top and bottom walls of which are open. The seat body has a first through hole on both sides along its width direction. The first through hole allows the side wall of the placement part to communicate with the outside. The movable block has a second through hole and a third through hole. The second through hole matches the first through hole, and the axis of the third through hole is arranged vertically and communicates with the second through hole. The first and second through holes are used for the connecting shaft to pass through so that the movable block can be installed in the placement part.

[0008] The connecting shaft has a fourth through hole that matches the third through hole. The third through hole and the fourth through hole form a mounting hole. One end of the connecting shaft has an end cap, and the other end has a first threaded hole. The outer diameter of the end cap is larger than the inner diameter of the first through hole. The fastener is screwed into the first threaded hole. The fastener and the end cap can lock the movable block and the mounting shaft at the same time.

The depth of the adjustment groove is less than the depth of the third through hole, and the adjustment groove penetrates the top or bottom end of the third through hole.

[0010] In the aforementioned guide rail clamp, the fixing components include a fixing rod and a handle. The fixing rod has a limiting plate at its body. The axis of the fixing rod is perpendicular to the surface of the limiting plate. The limiting plate divides the fixing rod into a threaded section and a connecting section. The handle is connected to the connecting section. The threaded section is screwed into the first threaded hole. The outer diameter of the limiting plate is larger than the inner diameter of the first through hole. The handle is used to drive the fixing rod to rotate.

[0011] In the aforementioned guide rail clamping seat, the fixing components also include a bolt and a first spring. The connecting section has a first flange with a prism-shaped structure. The first flange is connected to the side of the limiting plate near the connecting section. The end of the connecting section away from the seat body has a second threaded hole. The bolt is screwed into the second threaded hole. The handle is slidably connected to the connecting section. The end of the handle near the limiting plate has a first groove that matches the first flange. The end of the handle away from the limiting plate has a second groove. The first spring is sleeved on the connecting section. One end of the first spring abuts against the bottom wall of the second groove, and the other end abuts against the nut of the bolt. The handle can move along the axial direction of the fixing rod to separate the first groove from the first flange.

[0012] In the aforementioned guide rail clamping seat, the fixing component also includes a washer and a rod. The washer has a fixing hole that matches the rod. The fixing hole is eccentrically set on the washer. The rod is inserted into the side of the seat body near the limiting plate. The washer is installed on the side of the seat body near the limiting plate through the fixing hole and the rod. The outer diameter of the washer is larger than the inner diameter of the first through hole. The threaded section of the fixing rod passes through the washer and is screwed into the first threaded hole. At this time, the limiting plate presses the washer against one side of the seat body.

[0013] In the aforementioned guide rail clamping seat, the movable parts also include an end cap and a torsion spring. The end cap has a fixing post, the axis of which coincides with the axis of the end cap. The end cap also has an eccentrically set lever. The seat body has a limiting rod on the side near the end cap. The limiting post is located above the first through hole. The torsion spring is sleeved on the fixing post. The two ends of the torsion spring extend radially, and the lever and the limiting rod are both located between the two ends of the torsion spring. The end cap is inserted into the fixing post.

[0014] In the aforementioned guide rail clamp, the clamping assembly includes an interface seat, a mounting shaft located at the bottom of the interface seat, and a groove at the bottom end of the mounting shaft for connecting a clamp to restrict the interface seat from disengaging from the movable block along the axial direction of the mounting hole.

[0015] In the aforementioned guide rail clamping seat, the top of the interface seat has a clamping rail, and the interface seat contains a push rod, a second spring, and a locking block. The interface seat also contains a first sliding groove, the length of which extends along the width direction of the clamping rail. The first sliding groove is located below the clamping rail. The interface seat also contains a second sliding groove, which is arranged opposite to the first sliding groove. The side wall of the first sliding groove near the second sliding groove has a fifth through hole, through which the first sliding groove communicates with the second sliding groove. The second sliding groove communicates with the clamping rail, and the locking block is slidably connected in the second sliding groove, with a portion of the locking block extending out from the clamping rail.

[0016] The push rod has a second flange, and the push rod is slidably connected to the first slide groove through the second flange. The end of the push rod passes through the fifth through hole and is threadedly connected to the locking block. The spring is sleeved on the push rod, and the two ends of the spring are respectively pressed against the second flange and the side wall of the first slide groove near the second slide groove.

[0017] Meanwhile, this application also provides a gun bipod, including a foot and a guide rail clamp, with foot mounting portions at both ends of the base along its length, and the foot being connected to the foot mounting portions in an angle-adjustable manner.

[0018] Compared with the prior art, the beneficial effects of this application are:

[0019] 1. This application features a modular design for the rail clamping base. By setting a mounting shaft at the bottom of the clamping assembly, and using a plug-in connection between the mounting shaft and the mounting hole, the rotation and swing adjustment functions of the clamping assembly are retained. At the same time, different clamping assemblies can be quickly replaced to adapt to different gun rails.

[0020] 2. This application provides an adjustment groove on the movable block. When the fixing part cooperates with the connecting shaft, it can not only clamp the movable block, but also simultaneously compress the adjustment groove to reduce the diameter of the third through hole and clamp the mounting shaft.

[0021] 3. In this application, a torsion spring is provided at the end cap of the connecting shaft. When the clamping assembly swings, the torsion spring can be compressed with the cooperation of the fixed post and the lever. After the locking is released, the rebound force of the torsion spring can realize the automatic reset of the clamping assembly.

[0022] 4. This application provides a push rod and a locking block inside the interface seat. The push rod can push the locking block out of the clamping rail, allowing for convenient adjustment of the clamping position of the firearm guide rail. Attached Figure Description

Detailed Implementation

[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 of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0038] Example 1

[0039] refer to Figures 1-6 A guide rail clamping base includes a base body 1, a movable member 2, a fixing member 3, and a clamping assembly 4. The movable member 2 is rotatably connected to the base body 1, and the rotation axis of the movable member 2 is arranged horizontally. The movable member 2 has a mounting hole 21, and the axis of the mounting hole 21 is perpendicular to the rotation axis of the movable member 2. The clamping assembly 4 is used to clamp an external gun guide rail. The bottom of the clamping assembly 4 has a mounting shaft 41 that matches the mounting hole 21. The clamping assembly 4 is inserted into the mounting hole 21 through the mounting shaft 41. The mounting shaft 41 can rotate within the mounting hole 21. The fixing member 3 is connected to the movable member 2 and can lock the movable member 2 and the mounting shaft 41 simultaneously.

[0040] In this design, regarding the angle adjustment function of the guide rail clamping seat, the movable part 2 is rotatably connected inside the seat body 1, and the rotation axis of the movable part 2 is arranged horizontally. That is to say, the clamping assembly 4 can swing in the vertical plane. At the same time, the axis of the mounting hole 21 is perpendicular to the rotation axis of the movable part 2, so the clamping assembly 4 can also rotate in the horizontal plane. Regarding the quick replacement function of the clamping assembly 4 of this guide rail clamping seat, the clamping assembly 4 is inserted into the mounting hole 21 through its own mounting shaft 41. After the locking of the fixing part 3 is loosened, quick replacement can be achieved by plugging and unplugging.

[0041] In this embodiment, the movable component 2 includes a connecting shaft 22 and a movable block 23. The base 1 has a placement part 11, the top and bottom walls of which are open. The base 1 has a first through hole 12 on both sides along its width direction. The first through hole 12 allows the side wall of the placement part 11 to communicate with the outside. The movable block 23 has a second through hole 232 and a third through hole 231. The second through hole 232 matches the first through hole 12. The axis of the third through hole 231 is arranged vertically and communicates with the second through hole 232. The first through hole 12 and the second through hole 232 are used for the connecting shaft 22 to pass through so that the movable block 23 can be installed in the placement part 11.

[0042] The connecting shaft 22 has a fourth through hole 222 that matches the third through hole 231. The third through hole 231 and the fourth through hole 222 form a mounting hole 21. One end of the connecting shaft 22 has an end cap 221 and the other end has a first threaded hole 223. The outer diameter of the end cap 221 is larger than the inner diameter of the first through hole 12. The fixing member 3 is screwed into the first threaded hole 223. The fixing member 3 and the end cap 221 cooperate to lock the movable block 23 and the mounting shaft 41 at the same time.

[0043] Specifically, the connecting shaft 22 passes through both the first through hole 12 and the second through hole 232, confining the movable block 23 within the placement part 11. It also forms a mounting hole 21 through the third through hole 231 and the fourth through hole 222. After the mounting hole 21 is connected to the mounting shaft 41, the connecting shaft 22 and the movable block 23 can rotate together. After installation, one end of the connecting shaft 22 contacts the base 1 via an end cap 221 for positioning, while the other end is threaded to the fixing member 3 via the first threaded hole 223 for positioning. During gradual tightening, the fixing member 3 and the end cap 221 cooperate to generate a clamping force, clamping the movable block 23 and the mounting shaft 41.

[0044] Furthermore, the movable block 23 also has an adjustment groove 233. The width of the adjustment groove 233 extends along the axial direction of the second through hole 232, and the depth of the adjustment groove 233 extends from one end of the third through hole 231 to the other end. The depth of the adjustment groove 233 is less than the depth of the third through hole 231, and the adjustment groove 233 penetrates the top or bottom of the third through hole 231.

[0045] Regarding the adjusting groove 233, its purpose is to reduce the width of the adjusting groove 233 by using the clamping force generated by the fixing member 3 and the end cap 221, thereby further reducing the width of the third through hole 231 and clamping the mounting shaft 41. In this embodiment, the adjusting groove 233 extends through the top end of the third through hole 231; in other embodiments, the adjusting groove 233 extends through the bottom end of the third through hole 231; both methods require ensuring that the depth of the adjusting groove 233 is greater than half the depth of the third through hole.

[0046] In this embodiment, the fixing member 3 includes a fixing rod 31 and a handle 32. The fixing rod 31 has a limiting plate 311 at its body. The axis of the fixing rod 31 is perpendicular to the plate surface of the limiting plate 311. The limiting plate 311 divides the fixing rod 31 into a threaded section 312 and a connecting section 313. The handle 32 is connected to the connecting section 313. The threaded section 312 is screwed into the first threaded hole 223. The outer diameter of the limiting plate 311 is larger than the inner diameter of the first through hole 12. The handle 32 is used to drive the fixing rod 31 to rotate.

[0047] Specifically, the fixed rod 31 is fixedly connected to the handle 32 through the connecting section 313 and threadedly connected to the first threaded hole 223 through the threaded section 312. The handle 32 drives the fixed rod 31 to rotate, and the limiting plate 311 and the end cap 221 cooperate to generate a clamping force to clamp the seat 1.

[0048] Furthermore, the fastener 3 also includes a bolt 36 and a first spring 35. The connecting section 313 has a first flange 314 with a prism-shaped structure. The first flange 314 is connected to the side of the limiting plate 311 near the connecting section 313. The end of the connecting section 313 away from the seat 1 has a second threaded hole 3131. The bolt 36 is screwed into the second threaded hole 3131. The handle 32 is slidably connected to the connecting section 313. The end of the handle 32 near the limiting plate 311 has a first groove 321 that matches the first flange 314. The end of the handle 32 away from the limiting plate 311 has a second groove 322. The first spring 35 is sleeved on the connecting section 313. One end of the first spring 35 abuts against the bottom wall of the second groove 322, and the other end abuts against the nut of the bolt 36. The handle 32 can move along the axial direction of the fixing rod 31 to separate the first groove 321 from the first flange 314.

[0049] In practical use, considering that the position of the handle 32 may affect the installation of the firearm during the tightening process, a first flange 314 is provided on the limiting plate 311. The handle 32 is slidably connected to the connecting section 313. In the initial state, the first spring 35 pushes the first groove 321 of the handle 32 to engage with the first flange 314. At this time, the handle 32 and the fixing rod 31 can rotate together. When it is found that the position of the handle 32 may affect the installation of the firearm, the user can pull the handle 32 away from the base 1 to compress the first spring 35. The first groove 321 and the first flange 314 separate, but the handle 32 and the connecting section 313 still remain slidably connected. Rotating the handle 32 can change the relative position of the handle 32 and the fixing rod 31. After releasing the handle 32, the first spring 35 drives the handle 32 to reset, and the first groove 321 and the first flange 314 return to the engaged state.

[0050] It should also be noted that because the first flange 314 adopts a prism-shaped structure, during the resetting process, the first groove 321 and the first flange 314 need to be aligned in terms of their edges in order for the first groove 321 and the first flange 314 to fit together.

[0051] Preferably, the fixing member 3 further includes a washer 33 and a rod 34. The washer 33 has a fixing hole 331 that matches the rod 34. The fixing hole 331 is eccentrically set on the washer 33. The rod 34 is inserted into the side of the seat 1 near the limiting plate 311. The washer 33 is installed on the side of the seat 1 near the limiting plate 311 through the fixing hole 331 and the rod 34. The outer diameter of the washer 33 is larger than the inner diameter of the first through hole 12. The threaded section 312 of the fixing rod 31 passes through the washer 33 and is screwed into the first threaded hole 223. At this time, the limiting plate 311 presses the washer 33 against one side of the seat 1.

[0052] Specifically, the fit between the rod 34 and the fixing hole 331 facilitates the installation of the washer 33 and ensures that the axis of the washer 33 coincides with the axis of the first through hole 12. The washer 33 also increases the contact area, making the clamping force distribution more uniform and avoiding clamping force concentration.

[0053] In this embodiment, the clamping assembly 4 includes an interface seat 42, with a mounting shaft 41 located at the bottom of the interface seat 42. The bottom end of the mounting shaft 41 has a groove 411, which is used to connect a clamp 412 to prevent the interface seat 42 from disengaging from the movable block 23 along the axial direction of the mounting hole 21. The interface seat 42 is used to clamp the gun rail and can be any interface seat 42 known to those skilled in the art, but its bottom must be fitted with a mounting shaft 41. Specifically, it can be a detachable mounting shaft 41, such as one connected by screws, or a fixed mounting shaft 41, such as one integrally formed with the interface seat 42. The cooperation between the groove 411 and the clamp 412 further prevents the mounting shaft 41 from separating from the mounting hole 21. Regarding the clamp 412, any clamp known to those skilled in the art can be used. Specifically, the outer diameter of a portion of the mounting shaft 41 is increased to be larger than the diameter of the mounting hole 21 to prevent separation during use.

[0054] Specifically, those skilled in the art know that there are various types of interface seats 42, such as interface seats 42 for clamping Picatinny rails, interface seats 42 for clamping Arca rails, and interface seats 42 for clamping wooden rails, etc. However, each type of interface seat 42 has a mounting shaft 41, which facilitates quick replacement of different interface seats 42.

[0055] Furthermore, the top of the interface seat 42 has a clamping rail 421, and the interface seat 42 has a push rod 422, a second spring 423, and a locking block 424. The interface seat 42 has a first sliding groove 425, the length of which extends along the width direction of the clamping rail 421. The first sliding groove 425 is located below the clamping rail 421. The interface seat 42 also has a second sliding groove 427, which is arranged opposite to the first sliding groove 425. The side wall of the first sliding groove 425 near the second sliding groove 427 has a fifth through hole 426, through which the first sliding groove 425 communicates with the second sliding groove 427. The second sliding groove 427 communicates with the clamping rail 421, and the locking block 424 is slidably connected in the second sliding groove 427, with a portion of the locking block 424 extending out from the clamping rail 421.

[0056] The push rod 422 has a second flange 4211. The push rod 422 is slidably connected to the first slide groove 425 through the second flange 4211. The end of the push rod 422 passes through the fifth through hole 426 and is threadedly connected to the locking block 424. The spring is sleeved on the push rod 422, and the two ends of the spring abut against the second flange 4211 and the side wall of the first slide groove 425 near the second slide groove 427, respectively.

[0057] In practical use, to facilitate adjustment of the locking position on the guide rail, a sliding push rod 422 is provided inside the interface seat 42. In the initial state, the locking block 424 limits the push rod 422 to ensure that the end of the push rod 422 away from the locking block 424 extends out of the interface seat 42. At the same time, the locking block 424 is partially located inside the clamping rail 421 to lock the firearm guide rail. The user can press the push rod 422 to compress the second spring 423 and push the locking block 424 out through the push rod 422, so that the locking block 424 is separated from the clamping rail 421. At this time, the firearm guide rail can change its relative position with the clamping rail 421. After releasing the push rod 422, the second spring 423 drives the locking block 424 and the push rod 422 to reset, so that the locking block 424 is locked back into the firearm guide rail.

[0058] Example 2

[0059] refer to Figures 7-10 Compared with embodiment 1, this embodiment 2 also has an automatic reset function. In this embodiment 2, the movable part 2 also includes an end cap 24 and a torsion spring 25. The end cap 221 has a fixing post 223. The axis of the fixing post 223 coincides with the axis of the end cap 221. The end cap 221 also has an eccentrically arranged lever 224. The seat 1 has a limiting rod 14 on the side near the end cap 221. The limiting post is located above the first through hole 12. The torsion spring 25 is sleeved on the fixing post 223. The two ends of the torsion spring 25 extend radially, and the lever 224 and the limiting rod 14 are both located between the two ends of the torsion spring 25. The end cap 24 is inserted into the fixing post 223.

[0060] In practical use, the compression of the torsion spring 25 requires the cooperation of the lever 224 and the fixing post 223. Specifically, when the clamping assembly 4 swings in the vertical plane, it drives the connecting shaft 22 to rotate, which in turn drives the eccentrically positioned lever 224 to swing. During the swinging process, the lever 224 contacts one end of the torsion spring 25 and pushes that end, while the other end contacts the fixing post 223 to prevent the torsion spring 25 and the connecting shaft 22 from rotating synchronously. Under the constraint of the fixing post 223, the distance between the two ends of the torsion spring 25 continuously increases, causing the torsion spring 25 to generate a rebound force, which is locked by the fixing member 3 when positioning is required. After the fixing member 3 is released, the rebound force of the torsion spring 25 can drive the connecting shaft 22 to reset, so as to restore the clamping assembly 4 to its initial state. Regarding the end cap 24 and the fixing post 223, they can be connected by threads or by plug-in connection.
