Description

Technical Field

[0001] The invention relates to the technical field of firearm accessories, and in particular to a sighting scope bracket. Background Art

[0002] The Type 95 rifle is a common rifle in the Chinese military and police fields. This model of rifle has a rail on the top that can be used to install a scope. The rail has special specifications and is not compatible with ordinary scopes. Only scopes designed specifically for it can be directly installed.

[0003] As the times change, the users of the Type 95 rifle are becoming more and more extensive, and the use environment and scenes are becoming more and more complex. People need to equip the Type 95 rifle with various types of scopes to adapt to the needs of the mission. Some users of the Type 95 rifle need to frequently and quickly shoot targets at different distances, and the standard mechanical scope of the Type 95 rifle cannot assist users in shooting targets at longer distances, which places high demands on the user's skills. Various types of optical sights can significantly improve the shooting accuracy and aiming speed of the Type 95 rifle.

[0004] Picatinny rails, derived from NATO rail standards, are becoming increasingly popular around the world. This standard of rails and its various matching products have become a widely respected choice in the world's military, police and civilian fields.

[0005] In order to adapt to more types of scopes, technicians in this field have proposed the following four modification schemes for the Type 95 rifle, but each modification scheme has certain defects:

[0006] (1) Replace the upper part of the Type 95 rifle with a Picatinny rail. This modification is a large project and will cause irreversible modifications to the firearm. Many units do not allow individuals to make irreversible custom modifications to firearms, and the modification requires professional tools;

[0007] (2) Replace the handguard of the Type 95 rifle with a Picatinny rail. With this modification, the mounting position of the sight is limited, and only red dot sights or holographic sights without pupil distance restrictions can be installed. And because the accessories are installed on the handguard, the user's gun holding posture will be restricted. In some cases, it will cause inconvenience to the user;

[0008] (3) Install a rail specification converter on the rail of the Type 95 rifle. With this modification solution, usually only one scope can be installed, and the expandability is relatively limited;

[0009] (4) Install a modification frame on the top of the firearm, with an internationally compatible rail attached to the frame. This modification scheme makes the overall weight of the rifle heavier, which will greatly affect the user experience and increase the user's physical exertion. Some products also require irreversible modification of the firearm.

[0010] like Fig.10 As shown, the handle structure of the Type 95 rifle is displayed. The top of the handle is similar to a U-shaped groove structure. The guide rail for installing the scope is located on the inner side of the U-shaped groove, and there are obstructions on both sides, which makes the general base and clamping method impossible to use. The common installation method is to cut off part of the handle to facilitate the installation of the scope, but this will cause irreversible damage to the structure of the handle.

DETAILED DESCRIPTION

[0038] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0039] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 and Fig.12As shown, this embodiment provides a scope bracket, including a base 1, a first mounting surface 11 for mounting a first scope 2 is provided on the top of the base 1, a side-mounted bracket 3 is detachably connected to the base 1, and the side-mounted bracket 3 includes an integrally formed connecting portion 31 and a mounting portion 32, a Picatinny rail 12 connected to the connecting portion 31 is provided on the base 1, the mounting portion 32 is gradually tilted downward in a direction away from the connecting portion 31, and a second mounting surface 321 for mounting a second scope 4 is provided on the top of the mounting portion 32. The above-mentioned first mounting surface 11 is located in a horizontal plane, and the second mounting surface 321 is gradually tilted downward in a direction away from the first mounting surface 11. Users can choose to install one or two scopes according to their own needs, and the expandability is strong.

[0041] refer to Fig.10 , Fig.11 and Fig.12 In this embodiment, the base 1 is directly mounted on the guide rail 51 of the 95-type rifle handle 5, which can meet the requirements of the pupil distance and the ergonomics of the gunner's gun holding posture. In addition, after the first sight 2 and the second sight 4 are installed, the cheek point of the 95-type rifle, the aiming center of the first sight 2 (eyepiece center) and the aiming center of the second sight 4 (eyepiece center) are projected on a vertical plane to form a first point 52, a second point 21 and a third point 41, respectively, wherein the distance between the first point 52 and the second point 21 is equal to the distance between the first point 52 and the third point 41, which is very consistent with the gunner's habit of switching the sight angle. Among them, the first sight 2 and the second sight 4 can be red dot sights or prism sights.

[0042] In this embodiment, the Picatinny rail 12 is an internationally universal rail, and the connection structure between the side-mounted bracket 3 and the Picatinny rail 12 is a universal installation structure of the Picatinny rail 12 accessories, which will not be elaborated here.

[0043] The bottom of the base 1 is provided with a dovetail groove 13, which is adapted to the guide rail 51 of the handle 5. Specifically, there are two dovetail grooves 13, which are respectively located at the two ends of the length direction of the base 1, and a clearance groove 14 connected to the dovetail groove 13 is provided between the two dovetail grooves 13 at the bottom of the base 1. The clearance groove 14 is a rectangular groove, and its width is greater than the maximum width of the dovetail groove 13 so as not to affect the matching between the dovetail groove 13 and the guide rail 51. A locking mechanism is also provided on the base 1, which is used to lock the dovetail groove 13 on the guide rail 51, so as to realize the detachable connection between the base 1 and the handle 5, so that the disassembly and assembly of the base 1 is more convenient.

[0044] Specifically, the locking mechanism includes a rotating shaft 6 passing through the base 1, the rotating shaft 6 includes a limit end 61 and a rod 62, the outer circumference of the limit end 61 is larger than the outer circumference of the rod 62, a connecting hole 15 is provided in the base 1 for rotationally cooperating with the rod 62, and the limit end 61 abuts against one end of the base 1. Four locking wheels 7 are provided on the outer circumferential anti-rotation sleeve of the rod 62, the locking wheels 7 are eccentrically arranged relative to the rod 62, four receiving grooves 16 connected with the connecting hole 15 are provided on the base 1, the four locking wheels 7 are arranged in the four receiving grooves 16 in a one-to-one correspondence, and the bottom opening of the receiving groove 16 is connected with the clearance groove 14, that is, the receiving groove 16, the clearance groove 14 and the dovetail groove 13 are connected with each other. In addition, the width of the receiving groove 16 is adapted to the thickness of the locking wheel 7 to prevent the locking wheel 7 from moving.

[0045] Further, refer to Figure 7 , the maximum distance a between the outer edge of the locking wheel 7 and the center of the rod 62 is greater than the distance between the center of the rod 62 and the top wall of the dovetail groove 13, and the minimum distance b between the outer edge of the locking wheel 7 and the center of the rod 62 is less than or equal to the distance between the center of the rod 62 and the top wall of the dovetail groove 13. It should be noted that, in this embodiment, the top walls of the dovetail groove 13 and the clearance groove 14 are coplanar. If the locking wheel 7 is eccentrically arranged, when the dovetail groove 13 and the guide rail 51 are slidably engaged, the rotation of the rotating shaft 6 can drive the locking wheel 7 to rotate, and during the rotation of the locking wheel 7, the distance between its outer edge and the guide rail 51 changes. Figure 7 In the state shown, the maximum distance a is at the top and the minimum distance b is at the bottom. At this time, the locking wheel 7 is completely located in the receiving groove 16 (refer to Figure 4 ), does not affect the relative sliding of the dovetail groove 13 and the guide rail 51, and is easy to install; Figure 7 After rotating the shaft 6 by about 180°, the maximum distance a is at the bottom and the minimum distance b is at the top. At this time, the outer edge of the locking wheel 7 extends out of the receiving groove 16 and extends into the clearance groove 14 (refer to Fig. 9 ), so that the outer edge of the locking wheel 7 can be pressed against the upper surface of the guide rail 51, thereby achieving locking of the base 1 and the handle 5.

[0046] Specifically, refer to Figure 6 and Figure 7 The rod 62 has two notches along its length direction, the two notches are symmetrically arranged, and a convex tooth 621 is formed between the two notches. An opening adapted to the cross-sectional shape of the rod 62 is provided on the locking wheel 7, and the opening has a tooth groove adapted to the convex tooth 621, thereby realizing a non-rotating connection between the locking wheel 7 and the rod 62.

[0047] Furthermore, the locking mechanism further includes a driving member 8 and a nut 9. The rotating shaft 6 is connected to the driving member 8 after passing through the base 1, and an opening identical to the locking wheel 7 is provided through the driving member 8, and the driving member 8 is slidably sleeved on the outer periphery of the rod 62. The rod 62 is threadedly connected to the nut 9 after passing through the driving member 8, so that the driving member 8 is sandwiched between the nut 9 and the base 1. In this embodiment, the driving member 8 is used to drive the rotating shaft 6 to rotate when locking, so that the locking wheel 7 is pressed against the guide rail 51. For ease of operation, the outer periphery of the driving member 8 is in the shape of a hexagonal prism.

[0048] Specifically, the driving member 8 is provided with a first limiting portion on one side close to the base 1, and the first limiting portion includes a plurality of convex ridges 81 uniformly distributed on the circumference at the end of the driving member 8; the base 1 is provided with a second limiting portion on one side close to the driving member 8, and the second limiting portion includes a plurality of grooves 17 provided on the end of the base 1, and the grooves 17 are adapted and correspond one to one with the convex ridges 81. In this embodiment, the convex ridges 81 and the grooves 17 are interlocked with each other, which can limit the circumferential position of the driving member 7 relative to the base 1, and prevent the driving member 8 from rotating relative to the base 1.

[0049] During installation, you can follow the steps below:

[0050] (1) Install the first sighting scope 2 or the side mounting bracket 3 to be assembled on the base 1 in advance;

[0051] (2) Place the locking wheels 7 with their open teeth facing upward into the four receiving grooves 16, respectively. The locking wheels 7 at the two ends have a smaller outer diameter of 9 mm, while the two middle locking wheels 7 have a larger outer diameter of 10 mm (the middle of the guide rail 51 is recessed downward to form a notch 511, which makes the upper surface of the guide rail 51 uneven. Therefore, the two middle locking wheels 7 need to be designed with larger sizes to abut against the upper surface of the notch 511 of the guide rail 51).

[0052] (3) Insert the rotating shaft 6 with the protruding teeth 621 facing upward into the connecting hole 15 of the base 1 and pass through the openings of the four locking wheels 7;

[0053] (4) Slidingly connecting the dovetail groove 13 of the base 1 to the guide rail 51 on the Type 95 rifle;

[0054] (5) The driving member 8 is sleeved on the outer periphery of the end of the rod 62 extending out of the base 1. At this time, the tooth groove at the opening of the locking wheel 7 faces upward, and the locking wheel 7 is completely accommodated in the accommodating groove 16 without interfering with the guide rail 51.

[0055] (6) Rotate the driving member 8 clockwise until it stops rotating. At this time, the tooth groove at the opening of the locking wheel 7 faces downward, and the outer edge of the locking wheel 7 extends out of the receiving groove 16 and presses against the guide rail 51;

[0056] (7) Tighten the nut 9 onto the end of the rod 62 so that the driving member 8 is clamped between the nut 9 and the base 1, and the ridge 81 of the driving member 8 cooperates with the groove 17 of the base 1 to limit the position.
