[0002] When using firearms with corner firing systems, the corner positioning cannot be accurately performed. It is necessary to repeatedly perform corner positioning or manually operate the positioning mechanism, which is complicated and inaccurate. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a stepping corner positioning device for a corner shooting system. The device adopts a stepping method, and each cornering operation only moves to the nearest positioning slot to achieve accurate corner positioning.

[0004] The objective of this invention is achieved as follows:

[0005] A stepping corner positioning device for a corner firing system includes a limiting group (1), a releasing group (2), and a fixed base (3). The limiting group (1) is located on one side of the fixed base (3), and the releasing group (2) is located at the lower end of the fixed base (3).

[0006] The limiting group (1) includes a limiting block (11). The limiting block (11) is mounted on the fixed seat (3) via a connecting shaft (7) and can rotate. The limiting block (11) is provided with a fan-shaped plate. The edge of the fan-shaped plate is uniformly provided with multiple limiting grooves along the circumferential direction. A conical release cap (12) is fixed between adjacent limiting grooves.

[0007] The release assembly (2) includes a seat (21) and a U-shaped top rod block (28). The upper end of the seat (21) is fixed to the fixed base (3). A latch (22) is slidably fitted on the seat (21) in the horizontal direction. A latch spring (23) is provided between the tail end of the latch (22) and the seat (21). The latch spring (23) is used to extend the latch (22) and engage it in a limiting groove of the fan-shaped plate. The latch (21) slides horizontally... The device is equipped with a pair of parallel push rods (212), which are symmetrically arranged on both sides of the latch (22). The push rods (212) are stepped shafts, and the small-diameter section of the push rods (212) is fitted with push rod springs (213). The push rod springs abut against the seat (21). The end of the small-diameter section of the push rods (212) passes through the seat (21) and is fixedly connected to the two parallel arms of the push rod block (28). The seat (21) is provided with a stepped hole, and the large-diameter end of the stepped hole accommodates... The push rod spring is positioned by the stepped surface of the stepped hole cooperating with the push rod spring. The small diameter end of the stepped hole is for the small diameter section of the push rod (212) to pass through. The push rod block (28) cooperates with the end face of the seat (21) to limit the front limit position of the push rod (212). The push rod shaft (29) is connected between the two parallel arms of the push rod block (28). A swing rod (25) is hinged on the push rod shaft (29). The free end of the swing rod (25) is provided with a boss. The latch (22) is provided with In the closed state of the sway bar (25), the boss is inserted into the sway bar positioning groove.

The lower end of the seat (21) is provided with an L-shaped lever (210). The driving end of the lever (210) is used to move the lever (210). The execution end of the lever (210) abuts against the large diameter end of the top rod (212).

[0008] When corner positioning, the lever (210) rotates, and the actuator of the lever (210) pushes the top rod (212) and the top rod block (28) to move backward. The top rod block (28) drives the swing rod (25) to move backward, and the swing rod (25) drives the latch (22) to move backward as well. When the latch (22) completely exits one of the limiting slots of the sector plate, the sector plate is unlocked. The limiting block (11) and the sector plate are rotated. The rotation method is the side tilting fixed seat (3). Under the action of gravity, the limiting block (11) rotates. During the rotation of the sector plate, the release cap (12) pushes the swing rod (25) upward. The boss of the swing rod (25) exits the latch positioning slot. The latch (22) moves forward under the push of the latch spring (23) to enter the other limiting slot of the limiting block (11) to complete the positioning. When the lever (210) is lowered, the push rod (212) returns to its original position under the action of the push rod spring (213), and the swing rod (25) returns to its original position under the action of the swing rod torsion spring (26).

[0011] Preferably, the limiting block (11) is provided with a strip-shaped positioning groove, which is a blind groove, and the release cap (12) is provided with a positioning boss that cooperates with the positioning groove to form a circumferential limiting of the release cap (12).

[0012] Preferably, the fitting parts of the limiting groove and the tenon (22) on the limiting block (11) are wedge-shaped.

[0013] Preferably, the tenon (22) is provided with a waist-shaped groove along the longitudinal direction, and a stop pin (24) is inserted into the waist-shaped groove. The stop pin (24) limits the longitudinal position of the tenon (22), and the two ends of the stop pin (24) are connected to the base (21).

[0014] Preferably, a limiting screw (13) is fixed on the sector plate, and an arc-shaped groove is provided on the fixing seat (3). The limiting screw (13) is embedded in the arc-shaped groove, and the two walls of the arc-shaped groove limit the extreme position of the sector plate rotation.

Employing a fully mechanical structure, the system achieves step-by-step cornering positioning of the corner firing system through a release, turning, and positioning mechanism. Each cornering operation rotates to the nearest positioning slot, ensuring accurate cornering. It allows for blind operation, is simple to operate, runs stably, and provides reliable positioning.

[0042] The limiting group 1 includes a limiting block 11, on which a release cap 12 and a limiting screw 13 are provided. The release cap 12 is riveted and fixed by passing through the limiting block 11 via a shaft, and the limiting screw 13 is threadedly connected to the limiting block 11.

[0043] The limiting assembly 1 can be connected to a device to expand its scope of use;

[0044] The mounting base 3 can be connected to a device to expand its scope of use;

[0045] The front end of the limiting block 11 can be connected to the firing device to meet the angle requirements of the firing device; the rear end of the fixing seat 3 can be connected and fixed to the base device for easy use; of course, it can also be installed in reverse.

[0046] The release assembly 2 and the fixed base 3 are connected by two base pins 4;

[0047] The latch 22 and latch spring 23 of the release assembly 2 are inserted into the seat 21 and the stop pin 24 is installed.

[0048] The seat 21 and lever 210 of the release assembly 2 are connected by lever pin 211, and lever 210 can rotate flexibly.

[0049] The swing rod 25 of the release assembly 2 is riveted to the torsion spring stop pin 27, and the push rod shaft 29 passes through the push rod block 28, the swing rod torsion spring 26, and the swing rod 25. The push rod shaft 29 is riveted to the push rod block 28 and cannot be removed.

[0050] The push rod 212 of the release assembly 2 passes through the push rod spring 213 and the seat 21, and is then connected to the push rod block 28 by a thread;

[0051] The handguard 5 is connected to the lever 210 of the release assembly 2 by two handguard screws 6. When in use, the handguard is held and the lever is pulled down to turn the lever, which is convenient to operate and easy to release.

[0052] The limiting assembly 1 and the fixing seat 3 are connected by a connecting shaft 7, and a cotter pin 8 is installed to prevent the connecting shaft 7 from retracting.

[0053] The limiting block 11 and the release cap 12 are positioned by bosses and grooves, and their orientation is fixed.

[0054] The limiting block 11 and the tenon 22 are wedge-shaped positioned so that no gap will be generated even if wear occurs, and there is no shaking after positioning.

[0055] The hand guard 5 is connected to the lever 210 of the release assembly 2 by two hand guard screws 6. When in use, the hand guard is held and the lever is pulled down to turn the lever, which is convenient to operate.

[0056] The limiting block 11 is provided with positioning wedge grooves, the number of which is determined as needed;

During the rotation, the release cap 12 of the limiting block 11 pushes the swing rod 25 upward, and the protrusion of the swing rod 25 exits the positioning groove of the latch 22. Under the push of the latch spring 23, the latch 22 moves to the left and enters the limiting groove of the limiting block 11, completing one unlocking, rotation and positioning.
