Description

Technical Field

[0001] This invention belongs to the field of weapon design and manufacturing technology, specifically relating to a pull-out firing structure, which is specially adapted to internal and external dual-barrel weapons to achieve convenient firing of the weapon and effectively optimize the overall size of the weapon. Background Technology

[0002] In the design of existing tube-type weapons, the vast majority adopt a single-tube structure, and their firing mechanism is usually fixedly connected to the tube body. This results in the weapon having a fixed and relatively long overall length when not in use, which brings many inconveniences to carrying, storing, and operating in confined spaces.

[0003] To address the aforementioned problems, there is an urgent need in the relevant technical field for a firing mechanism that can effectively shorten the length of weapons. Based on this, the present invention proposes a pull-out firing mechanism that achieves weapon firing through a pull-out action. While ensuring firing reliability, it can significantly reduce the overall length of the weapon, improving its portability and operational flexibility. Summary of the Invention

[0004] Technical solution

[0005] The pull-out firing structure disclosed in this invention is integrally assembled inside the outer casing (i.e., outer cylinder) of an inner and outer double-barrel weapon. Its core components include a limiting block, a limiting block spring plate, a firing pin slider, a trigger, a trigger spring plate, a slider and a slide rail, a firing pin spring, and a firing pin. The connection relationship and structural layout of each component are as follows:

[0006] Limiting block and limiting block spring: The limiting block is movably set at the front opening of the outer cover, and the limiting block spring is installed below the limiting block with its elastic force direction facing upward, providing a reset support for the limiting block. Under normal conditions, the limiting block is kept partially protruding inside the outer cover under the action of the limiting block spring, thus achieving initial limiting.

[0007] The firing pin slider and the slide rail: The slide rail extends along the axis of the outer cover, the slider slides in conjunction with the slide rail, the firing pin slider is fixedly connected to the slider, and can reciprocate linearly along the slide rail with the slider; at the same time, the firing pin slider contacts the limit block, and can move synchronously with the limit block in the initial stage of the pull action.

[0008] Trigger and trigger spring: The trigger is rotatably connected to a preset fulcrum inside the outer casing. The trigger spring is fitted onto the trigger's rotating shaft to provide a reset torque for the trigger. Under normal conditions, the blocking end of the trigger is in the extended state, which can block the moving firing pin slider. The operating end of the trigger extends to the outside of the outer casing for easy operation by the user.

[0009] Firing pin and firing pin spring: The firing pin is set along the firing axis of the weapon, with one end facing the primer of the ammunition and the other end slidingly engaging with the firing pin slider; the firing pin spring is sleeved on the outside of the firing pin, with one end abutting against the end face of the firing pin slider and the other end abutting against the limiting step of the firing pin. Under normal conditions, the firing pin spring is in a naturally extended state.

[0010] Slide rail limiting rod: An integrally formed limiting rod is provided at the rear end of the slide rail. The limiting rod is perpendicular to the length direction of the slide rail and is used to limit the end of the stroke of the firing pin slider to ensure that the firing mechanism is pulled into place.

[0011] Work process

[0012] The firing process of this pull-out firing mechanism is achieved through the relative movement between the pull-out outer cover and the inner cylinder. The specific steps are as follows:

[0013] 1. Initial pull-out stage: The user pulls the weapon's outer cover (or the inner cylinder component connected to the slide rail) backward. At this time, the limiting block at the front opening of the outer cover is subjected to the squeezing force of the inner wall of the outer cover, which overcomes the elastic force of the limiting block spring and moves downward, compressing the limiting block spring. Since the firing pin slider is in contact with the limiting block, under the action of the limiting block, the firing pin slider moves backward along the slide rail with the slider. During this process, the trigger is in the normal blocking state.

[0014] 2. Firing pin slider limiting stage: When the firing pin slider moves backward and contacts the blocking end of the trigger, the trigger maintains its blocking posture under the action of the trigger spring. The firing pin slider is blocked by the trigger and cannot continue to move backward with the slide rail. At this time, the relative position of the firing pin slider and the firing pin has not changed, and the firing pin spring is still in a naturally extended state and has not been compressed.

[0015] 3. Compression stage of the firing pin spring: As the user continues to pull the slide rail (or outer cover) backward, the firing pin slider is fixed and limited by the trigger and cannot move backward further, while the slide rail continues to move backward under the action of the pulling force. During this process, the slide rail drives the related connecting structure to move through the slider, so that the firing pin slider and the slide rail produce relative displacement. The firing pin slider compresses the firing pin spring, and the firing pin spring is gradually compressed and accumulates elastic potential energy.

[0016] 4. Pull-out and Limiting Stage: The slide rail continues to move backward until the firing pin slider touches the limiting rod on the slide rail. At this time, the firing structure completes the pull-out action and reaches the firing preparation position. At the same time, the squeezing force of the inner wall of the outer casing on the limiting block disappears. Under the elastic force of the limiting block spring plate, it resets upward and protrudes back into the outer casing, forming a double limit on the firing pin slider and the slide rail, ensuring that the firing structure is stably kept in the ready-to-fire state.

[0017] 5. Firing phase: When the user pulls the trigger, the trigger rotates around the pivot point, and its blocking end retracts downward, releasing the obstruction to the firing pin slider; the compressed firing pin spring releases its elastic potential energy instantaneously, pushing the firing pin to move rapidly forward along the axis, and the firing pin strikes the primer of the ammunition, thus firing the weapon.

[0018] Invention Effects

[0019] 1. Significantly shortens weapon length: This invention adopts a pull-out firing structure, which combines the firing action with the weapon length adjustment. When not in use, the firing structure is in a retracted state, which can effectively shorten the overall length of the weapon and improve the convenience of carrying and storing it, especially suitable for operation scenarios in confined spaces.

[0020] 2. High firing reliability: Through the multiple limiting designs of the limit block, trigger, and slide rail limit rod, the movement of each component of the firing structure is ensured to be precise and controllable during the pulling process, avoiding problems such as accidental firing or incomplete firing; at the same time, the reset action of the limit block spring and trigger spring is stable, further improving the working reliability of the structure.

[0021] 3. Simple structure and easy assembly: The firing structure of this invention consists of multiple standardized components with clear connections between them. The assembly process is simple, which facilitates mass production and subsequent maintenance, and can effectively reduce the manufacturing cost of weapons.

[0022] 4. High adaptability: This pull-out firing mechanism is specifically designed for internal and external dual-barrel weapons. Its structural dimensions can be flexibly adjusted according to different models of barrel weapons, and it has wide adaptability and can be applied to a variety of types of barrel weapons.

[0028] The limiting block (2) is made of engineering plastic material, and its upper end face is an arc structure to match the extrusion trajectory of the inner wall of the outer cover (1);

[0029] The slide rail (8) consists of two parallel metal guide rails, the slider (7) is a sliding seat that matches the slide rail (8), and the firing pin slider (4) is welded and fixed to the slider (7).

[0030] The trigger spring (6) is a torsion spring, which is fitted on the rotating shaft of the trigger (5), and its two ends are respectively engaged with the trigger (5) and the inner wall of the outer cover (1);

[0031] The front end of the firing pin (10) is a conical firing head, and the middle part is provided with an annular limiting step. The rear end of the firing pin spring (9) abuts against the limiting step.

[0032] The limiting rod (11) is integrally formed with the slide rail (8), and its axis is perpendicular to the length direction of the slide rail (8).

[0033] In this embodiment, the pull-out firing structure is assembled inside the outer casing (1) of the inner and outer double-barreled weapon. The outer casing (1) is made of aluminum alloy and has a limit block mounting groove at its front opening. The limit block 2 is made of engineering plastic and is movably embedded in the mounting groove. A metal limit block spring plate (3) is fixed on the inner wall of the outer casing 1 below the limit block (2). The upper end of the limit block spring plate (3) abuts against the bottom of the limit block (2). Under normal conditions, the limit block (2) is lifted up, so that the upper end of the limit block (2) protrudes out of the mounting groove. The slide rail (8) consists of two parallel metal guide rails, which are fixed to the outer wall of the inner cylinder by screws and extend along the axis of the inner cylinder. The slider (7) is a sliding seat that matches the slide rail (8). The firing pin slider (4) is made of alloy steel and is fixedly connected to the slider (7) by welding. The front end of the firing pin slider (4) is in contact with the rear end of the limit block (2).

[0034] The trigger (5) is rotatably connected to the bracket on the inner wall of the outer cover (1) via a stainless steel rotating shaft.

The limiting block (2) compresses the limiting block spring (3) downward, and at the same time pushes the firing pin slider (4) to move backward along the slide rail (8) with the slider (7). When the firing pin slider (4) contacts the blocking part of the trigger (5), the trigger (5) prevents the firing pin slider (4) from continuing to move under the action of the trigger spring (6). Continue to pull the outer cover (1). The slide rail (8) moves backward relative to the firing pin slider (4). The firing pin slider (4) squeezes the firing pin spring (9) to compress it. When the firing pin slider (4) contacts the limiting rod (11), it is pulled into place. The limiting block (2) resets under the action of the limiting block spring (3) and locks the firing structure. Pull the trigger (5). The blocking part retracts. The firing pin spring (9) pushes the firing pin (10) forward to fire.
