Description

Technical Field

[0001] The present application belongs to the technical field of gun supports, and specifically relates to a clamping seat for a gun rail. Background Art

[0002] With the continuous pursuit of shooting accuracy and operational convenience in modern weaponry, rail systems (such as Picatinny rails and MIL-STD-1913 rails) have become important standards for the assembly of firearm accessories. These rails provide a universal mounting platform for various accessories (such as lighting equipment, laser pointers, grips, sights, bipods, etc.).

[0003] As an important auxiliary device, tripods are widely used in shooting sports, hunting, and military operations. They can improve shooting accuracy and operational stability. Tripods are generally connected to the rail system through their clamping base. Currently, the commonly used clamping methods mainly include the following categories:

[0004] Bolt-on clamping: This clamping method uses mechanical fasteners such as bolts and nuts to clamp the guide rail in the clamping seat. The overall structure is simple and the manufacturing cost is low, but it requires tools for tightening and is cumbersome to adjust. For example, in the technical solution disclosed in Chinese patent CN202066417U, the guide rail is locked using a guide rail locking bolt.

[0005] Quick-release clamping uses a spring or quick-release mechanism to quickly clamp and release. This is convenient and often used for quick adjustments, but manual activation of the quick-release mechanism is still required to loosen or lock the rail. For example, the technical solution disclosed in Chinese patent CN108871050A uses a lever, a first countersunk screw, and a knob to lock the rail.

[0006] Therefore, the technical problem that needs to be solved in this case is: how to improve the convenience of disassembly and assembly of the gun rail and the clamping seat. Summary of the Invention

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0037] Example 1

[0038] refer to Figures 1 to 10 A clamping seat for a gun rail includes a base 1, a first clamping block 2, a second clamping block 3, and a control member 4; the first clamping block 2 and the second clamping block 3 form a clamping groove E for clamping the rail of an external device;

[0039] The base 1 and the first clamping block 2 are connected by a connecting member 5; the connecting member 5 is used to enable the base 1 and the first clamping block 2 to move relative to each other and to be inseparable; the control member 4 is used to switch the base 1 and the first clamping block 2 between a state in which they can move relative to each other and a state in which they are fixed relative to each other.

[0040] A guide assembly 6 is provided between the second clamping block 3 and the base 1; the guide assembly 6 includes a guide post 61 and a guide slot 62; the two ends of the guide slot 62 are end A 101 and end B 102; when the guide post 61 moves from end A 101 to end B 102 of the guide slot 62, the left-right distance between the second clamping block 3 and the first clamping block 2 increases to a maximum; when the guide post 61 moves from end B 102 to end A 101 of the guide slot 62, the left-right distance between the second clamping block 3 and the first clamping block 2 is minimized;

[0041] An elastic member 7 is provided between the first clamping block 2 and the second clamping block 3 ; the elastic member 7 is used to drive the guide column 61 to move to the B end 102 when the base 1 and the first clamping block 2 are in a state where they can move forward and backward relative to each other.

[0042] It should be noted that the clamping slot E formed by the first clamping block 2 and the second clamping block 3 is a standard clamping slot E. The clamped object is selected from a Picatinny rail (also known as a MIL-STD-1913 rail), but it is not limited to a Picatinny rail. This embodiment is described using a Picatinny rail only. It should also be noted that a Picatinny rail is fixed to a firearm, so when describing a Picatinny rail in this embodiment, it refers to a firearm equipped with a Picatinny rail.

[0043] It should also be noted here that the clamping seat of the gun rail is only a part of the gun support and needs to be installed on the support leg when in use. For other structures of the gun support, please refer to the technical solution disclosed in Chinese patent CN217738021U. Other parts are not within the scope of protection of this application.

[0044] Under this design, the base 1 and the first clamp 2 are initially in a fixed state relative to the front and rear. The operator switches the base 1 and the first clamp 2 to a state where they can move relative to the front and rear through the control member 4, and simultaneously pushes the first clamp 2 and the second clamp 3 forward. During the forward movement of the second clamp 3, the guide column 61 moves along the length direction of the guide groove 62 from the A end 101 of the guide groove 62 to the B end 102. At the same time, during the movement, the elastic member 7 pushes the second clamp 3 to move away from the first clamp 2, so that the left and right distance between the second clamp 3 and the first clamp 2 is increased to the maximum. The Picatinny rail is then installed in the clamping groove E. At this time, the width of the clamping groove E is greater than the width of the Picatinny rail. After installation, the operator can drive the first clamp 2 and the second clamp 3 to clamp the Picatinny rail in the following manner, specifically:

[0045] The first method is that the operator moves the first clamping block 2 and the second clamping block 3 backward to restore the first clamping block 2 and the second clamping block 3 to their initial state, and switches the state in which the base 1 and the first clamping block 2 are fixed relative to each other front and back;

[0046] The second method is that the operator pushes the base 1 forward, that is, pushes the base 1 and the supporting leg portion below the base 1. At this time, the first clamp 2 and the second clamp 3 are in a stationary state relative to the firearm, and the base 1 moves forward to restore the control member 4 to its initial state, and the base 1 and the first clamp 2 switch to a relatively fixed state in the front and rear direction.

[0047] The third method is that the operator pulls the firearm backward. The principle of this method is similar to the first method, except that the driven object is different. However, pulling the firearm backward is equivalent to moving the first clamping block 2 and the second clamping block 3 backward. Therefore, the third method will not be described in detail in this embodiment.

[0048] The above three methods can enable the first clamping block 2 and the second clamping block 3 to clamp the Picatinny rail. In terms of convenience, the second method is the most convenient.

[0049] In this embodiment, the control member 4 is a spring plunger, and a vertically arranged first threaded hole (not shown in the figure) is provided in the base 1. The top of the first threaded hole is provided with a first through hole 11 connected to the outside. The spring plunger is threadedly connected to the first threaded hole, and the column head 41 of the spring plunger extends from the first through hole 11 to the outside of the base 1; the first clamping block 2 is provided with a second through hole 21 corresponding to the first through hole 11 above and below, and the column head 41 can be extended into the second through hole 21 to limit the movement of the first clamping block 2 along the length direction of the base 1.

[0050] The spring plunger is a standard component in this field, and the threads on its outer wall are well known in the art. For details on its structure, please refer to Baidu Encyclopedia. Specifically, the spring plunger's stud 41 cooperates with the second through-hole 21 to restrict the movement of the first clamping block 2 along the length of the base 1. To switch states, the spring plunger's stud 41 is driven downward, clearing the second through-hole 21, switching the first clamping block 2 and base 1 to a state where they can move relative to each other.

[0051] Furthermore, a vertically arranged connecting hole 22 is provided in the first clamping block 2, and the connecting hole 22 is connected to the second through hole 21. The second through hole 21 and the connecting hole 22 are arranged in sequence from bottom to top along the height direction of the first clamping block 2. A pressing piece 8 is movably connected in the connecting hole 22. When the column head 41 is located in the second through hole 21, the column head 41 lifts the pressing piece 8. At this time, pressing the pressing piece 8 can cause the column head 41 to move downward and leave the second through hole 21.

[0052] Specifically, the pressing piece 8 is placed in the connecting hole 22 in a movable connection manner, that is, the pressing piece 8 can move along the height direction of the connecting hole 22 and descend due to its own weight. Therefore, the pressing piece 8 is lifted up by the column head 41. Not only can the first clamping block 2 be limited by the column head 41, but the pressing piece 8 can also be reset. The pressing piece 8 does not need to be provided with other elastic reset parts.

[0053] Furthermore, the pressing member 8 includes a movable column 81 and a pressing column 82. The movable column 81 is arranged vertically and movably connected in the connecting hole 22. The movable column 81 can move up and down along the height direction of the connecting hole 22. A first strip-shaped through hole 23 is provided on the other side of the length direction of the first clamping block 2. The axis of the first strip-shaped through hole 23 extends along the width direction of the first clamping block 2. The first strip-shaped through hole 23 is connected to the connecting hole 22. One end of the pressing column 82 is connected to the side wall of the movable column 81, and the other end passes through the first strip-shaped through hole 23 to the outside of the first clamping block 2.

[0054] In actual use, the movable column 81 is mainly used to press the column head 41 to make the column head 41 move downward, and the pressing column 82 can provide a convenient pressing method. Specifically, by setting a first strip-shaped through hole 23 on the first clamping block 2, a movable stroke is provided for the pressing column 82. When the pressing column 82 is pressed downward, the pressing column 82 drives the movable column 81 downward along the length direction of the first strip-shaped through hole 23, so that the movable column 81 drives the column head 41 downward to leave the second through hole 21.

[0055] In this embodiment, the guide column 61 is arranged at the bottom of the second clamping block 3, the guide groove 62 is arranged on the base 1, the guide column 61 extends into the guide groove 62, the guide groove 62 is an arc-shaped structure, and the guide groove 62 also has an elastic block 63. The side wall of the elastic block 63 forms the side wall of the guide groove 62 away from the first clamping block 2. A second threaded hole 15 is provided on one side in the length direction of the base 1. The axis of the second threaded hole 15 extends along the width direction of the base 1. The second threaded hole 15 is connected to the guide groove 62. The second threaded hole 15 is used to connect the top screw D to tighten the elastic block 63 to the guide column 61.

[0056] Under this design, the function of the guide groove 62 is to guide the direction of the second clamping block 3 and prevent the second clamping block 3 from separating from the first clamping block 2. When the first clamping block 2 is pushed, the first clamping block 2 drives the second clamping block 3 to move forward together through the elastic member 7. At this time, the guide column 61 at the bottom of the second clamping block 3 moves from the A end 101 to the B end 102 under the guidance of the guide groove 62. At the same time, the elastic member 7 pushes the second clamping block 3 to move away from the first clamping block 2, so that the left and right distance between the second clamping block 3 and the first clamping block 2 is increased to the maximum. In addition, since the second clamping block 3 is continuously subjected to the elastic action of the elastic member 7, the guide column 61 is initially pressed against the side wall of the guide groove 62 away from the first clamping block 2. During the entire movement process, the guide column 61 will move along the side wall. In order to avoid hard contact between the guide column 61 and the guide groove 62, an elastic block 63 is added to the guide groove 62. Specifically, the elastic block 63 is a J-shaped structure, and the elastic block 63 has a first J-shaped side wall and a second J-shaped side wall located outside the first J-shaped side wall. A contoured portion matching the first J-shaped side wall is provided in the guide groove 62, and the elastic block 63 is pressed against the guide column 61 by connecting the top screw D through the second threaded hole 15.

[0057] In a preferred embodiment, there are two guide grooves 62 , which are spaced apart along the length direction of the base 1 , and the number of guide columns 61 , second threaded holes 15 , top screws D, and elastic blocks 63 matches the number of guide grooves 62 .

[0058] In other embodiments, more than two guide grooves 62 may be used. The specific number can be determined by the operator based on actual conditions. However, considering the size of the base 1 and while ensuring stability, the number of guide grooves 62 should be as small as possible. Therefore, in this embodiment, two guide grooves 62 are used. Correspondingly, the number of guide posts 61, second threaded holes 15, top screws D, and elastic blocks 63 is also two.

[0059] In this embodiment, the base 1 also has a third through hole 12, the axis of the third through hole 12 extends along the height direction of the base 1, and the top of the third through hole 12 is stepped; a third threaded hole 13 is provided on the other side of the length direction of the base 1, and the axis of the third threaded hole 13 extends along the width direction of the base 1. The third threaded hole 13 is connected to the third through hole 12, and the third through hole 12 is used to connect the step screw F, which is used to connect to the tripod of the peripheral device so that the base 1 can rotate around the axis of the third through hole 12, and the third threaded hole 13 is used to connect the handle screw C, which is used to fix the base 1 at a preset rotation angle.

[0060] In actual application, the base 1 also needs to form a tripod with the support leg of the peripheral device. Specifically, the base 1 is connected to the support leg of the peripheral device through a step screw F. The step part of the step screw F can provide the base 1 with a rotation function, and the step screw F makes the base 1 and the support leg of the peripheral device inseparable. The third threaded hole 13 connected to the third through hole 12 is used to connect the handle screw C. The user can rotate the base 1 to a suitable angle according to his or her own needs, and then rotate the handle screw C so that the end of the handle screw C is pressed against the connecting part between the support leg of the peripheral device and the base 1 to fix the base 1 at the current rotation angle.

[0061] Furthermore, the connecting member 5 includes a connecting block 51, the length of which extends along the length direction of the base 1, the vertical cross-section of the connecting block 51 is trapezoidal, the bottom of the connecting block 51 is provided with a clamping block 511, and the base 1 is provided with a clamping groove 14 matching the shape of the clamping block 511; the first clamping block 2 is provided with a vertically arranged second strip-shaped through hole 26, the length of the second strip-shaped through hole 26 extends along the length direction of the first clamping block 2, the length of the second strip-shaped through hole 26 is greater than the length of the connecting block 51, the vertical cross-section of the second strip-shaped through hole 26 is trapezoidal, the connecting block 51 passes through the second strip-shaped through hole 26 to connect the clamping block 511 and the clamping groove 14, and the connecting block 51 is connected to the base 1 by bolts.

[0062] Specifically, the trapezoidal structure of the connecting block 51 matches the trapezoidal structure of the second strip-shaped through hole 26. The trapezoidal structure of the connecting block 51 fits the trapezoidal structure of the second strip-shaped through hole 26, providing the first clamping block 2 with a forward and backward movement function, and also limiting the separation of the first clamping block 2 from the base 1. At the same time, the length of the second strip-shaped through hole 26 is greater than the length of the connecting block 51, so that the first clamping block 2 can move along the length direction of the base 1. In a preferred embodiment, the length of the second strip-shaped through hole 26 matches the A end 101 and the B end 102 of the guide groove 62. That is, when one end of the connecting block 51 along its length direction contacts one end of the second strip-shaped through hole 26 along its length direction, the guide column 61 is exactly located at the A end 101 of the guide groove 62. Similarly, after pushing the first clamping block 2, when the other end of the connecting block 51 along its length direction contacts the other end of the second strip-shaped through hole 26 along its length direction, the guide column 61 is exactly located at the B end 102 of the guide groove 62.

[0063] Furthermore, the elastic member 7 includes a connecting column 71 and a spring 72. The axis of the connecting column 71 extends along the width direction of the base 1. The first clamping block 2 is provided with a blind hole 24 on one side along its length direction, and the second clamping block 3 is provided with a fourth threaded hole 31 on one side along its length direction. The connecting column 71 has a thread at one end along its length direction and a receiving groove 711 at the other end. One end of the spring 72 is located in the receiving groove 711. One end of the connecting column 71 along its length direction is threadedly connected to the fourth threaded hole 31 through a thread, and the other end is located in the blind hole 24.

[0064] Specifically, one end of the connecting column 71 along its length direction is connected to the fourth threaded hole 31 on the second clamping block 3 through a thread, and the other end of the connecting column 71 along its length direction accommodates one end of the spring 72 through the accommodating groove 711, and the spring 72 and the connecting column 71 are only inserted into the accommodating groove 711, and the end of the connecting column 71 with the accommodating groove 711 is inserted into the blind hole 24. At this time, the other end of the spring 72 is tightly pressed against the blind hole 24 and is in a compressed state. The second clamping block 3 is continuously subjected to the elastic force of the spring 72, and the second clamping block 3 is in a stable state through the cooperation of the guide column 61 and the guide groove 62 and the limiting of the second clamping block 3 by the connecting column 71 in the blind hole 24.

[0065] In practical applications, in order to ensure the stability of the second clamping block 3 , two elastic members 7 may be used.

[0066] In this embodiment, the first clamping block 2 has a first V-shaped groove 32, the length of the first V-shaped groove 32 extends along the length direction of the first clamping block 2 and passes through the first clamping block 2, and the first V-shaped groove 32 faces the second clamping block 3; the second clamping block 3 has a second V-shaped groove 25, the length of the second V-shaped groove 25 extends along the length direction of the second clamping block 3 and passes through the second clamping block 3, and the second V-shaped groove 25 faces the first clamping block 2. The first clamping block 2 also has a protrusion 27, and the protrusion 27 is located between the first V-shaped groove 32 and the second V-shaped groove 25. The first V-shaped groove 32, the second V-shaped groove 25, and the protrusion 27 constitute a clamping groove E.

[0067] The clamping groove E formed by the first V-groove 32, the second V-groove 25 and the protrusion 27 is an existing technology.
