Description

Technical Field

[0001] The present invention relates to the technical field of conventional weapons, in particular to a quick assembly and disassembly mechanism for a firearm firing device. Background Art

[0002] Large-caliber vehicle-mounted machine guns typically consist of a gun body, a vehicle-mounted gun carriage, a belt clip, and accompanying accessories. The vehicle-mounted gun carriage is typically fixed to the vehicle hull, artillery platform, or other mounting platform and remains in place year-round. The gun body and belt clip are typically stored inside the vehicle for safety during non-combat situations. They are only mounted on the vehicle-mounted gun carriage for combat or training missions, and are typically removed during non-combat situations. To facilitate gun assembly and disassembly, as well as operational use, large-caliber vehicle-mounted machine guns are typically designed with the firing mechanism integrated into the vehicle-mounted gun carriage. The firing mechanism is then installed onto the breech block (the breech block) at the rear of the gun body using a tool. The gun body is then fired by squeezing the firing handle (which is connected to the trigger via a wire cable. When the firing handle is squeezed, the force is transmitted to the trigger via the wire cable, triggering the firing action). Because the firing mechanism is connected to the gun body using a clamp and bolt connection, installation requires first fitting the clamp onto the breech block, then rotating the clamp back and forth around the axis of the breech block while simultaneously pressing the trigger backward and downward to allow the firing levers to sequentially pass in front of the trigger. Finally, tighten the bolts on the clamp with a tool to complete the installation. Disassembly also requires the use of a tool, following the reverse installation sequence. The entire installation and disassembly process is cumbersome and, without tools, impossible to complete, making it extremely inconvenient. Summary of the Invention

[0020] A quick assembly and disassembly mechanism for a firearm firing device, comprising a gun body (not shown), a butt body 1, the butt body 1 having a breech block, a trigger 4, and a clamp 10 for slidingly fitting on the breech block. A mounting strip is axially provided on the clamp 10, and a mounting space is provided between the mounting strip and the breech block. A hook 8 is longitudinally provided in the mounting space. The hook 8 is in the shape of a strip, and the middle portion of the hook 8 is hinged to the clamp 10 via a hook shaft 11. The two ends of the hook 8 are respectively a driving end and a hook end. The hanging end of the hook 8 is provided with a tenon, and the tenon of the hook 8 is provided on the breech block corresponding to the tenon of the hook 8. A hook spring 9 is also provided between the hook 8 and the clamp 10. The hook spring 9 is located between the tenon of the hook 8 and the hook shaft 11. When the clamp 10 is put on the breech block of the gun butt body 1 and is in place, under the action of the hook spring 9, the tenon of the hook 8 is embedded in the waist-shaped positioning groove on the breech block and positioned. The driving end of the hook 8 is provided with a handle, which is used to manually control the hook 8 and make the tenon of the hook 8 disengage from the waist-shaped positioning groove on the breech block.

[0021] A mounting hole is provided on the mounting strip of the clamp 10 in the longitudinal direction, and a wire rope shaft 3 is fixed in the mounting hole. A lever pin 7 is provided on the outer end of the wire rope shaft 3 along the radial direction of the clamp 10. A firing lever left part 2 and a firing lever right part 5 (a functional component of the firing device, which can fully fire the firearm only with a firing lever, and the present invention creatively splits the firing lever into two parts and assembles them together through a stop and a torsion spring) are hinged on the lever pin 7. A firing lever torsion spring 6 is sleeved on the lever pin 7, and the two spring feet of the firing lever torsion spring 6 act on the firing lever left part 2 and the firing lever right part 5 respectively. The hinged end of the right part 5 of the rod is provided with a stop. Under the spring force of the firing lever torsion spring 6, the left part 2 of the firing lever and the right part 5 of the firing lever are in an open state. The hinged ends of the left part 2 of the firing lever and the right part 5 of the firing lever are circumferentially limited by the stop. When the clamp 10 is put into place on the breech block of the butt body 1, the left part 2 of the firing lever and the right part 5 of the firing lever are behind the trigger 4. In the process of putting on the clamp 10, due to the obstruction of the trigger 4, the left part 2 of the firing lever and the right part 5 of the firing lever cannot pass over the trigger 4. The left part 2 of the firing lever and the right part 5 of the firing lever rotate and compress the firing lever torsion spring 6 to make way for the trigger 4.

[0022] When the trigger 4 is pulled backward, the rear end of the trigger 4 forces the left part 2 of the firing lever and the right part 5 of the firing lever to rotate around the lever pin, and the left part 2 of the firing lever and the right part 5 of the firing lever overcome the spring force of the firing lever torsion spring 6 and rotate and contract until the trigger 4 completely passes the left part 2 of the firing lever and the right part 5 of the firing lever. The left part 2 of the firing lever and the right part 5 of the firing lever return to their original positions under the action of the firing lever torsion spring 6. When the trigger 4 is released, the trigger 4 returns to the front under the action of the spring force of the gun body block spring (gun body component, not shown). At this time, the left part 2 of the firing lever and the right part 5 of the firing lever are in front of the trigger 4, and the firing device is installed.

[0023] During disassembly, press the trigger 4 backward, and the trigger 4 will give way to the left part 2 of the firing lever and the right part 5 of the firing lever. At the same time, press the left part 2 of the firing lever and the right part 5 of the firing lever inward (backward) until the trigger 4 can pass through the side of the left part 2 of the firing lever and the right part 5 of the firing lever by itself. The trigger 4 is reset and the firing device is released.

[0024] Press down the handle of the hook 8 and pull the clamp 10 backward to disassemble the firing device.

[0025] A locating pin is provided on the mounting strip of the clamp 10, and the locating pin passes through the wire rope shaft 3 to form a limit for the wire rope shaft 3. A limit head is provided at the end of the locating pin, and the limit head forms an axial positioning for the locating pin. The hook 8 is provided with a spring hole corresponding to the limit head of the locating pin, and the hook spring 9 is located in the spring hole. The outer end of the hook spring 9 acts on the limit head to prevent the locating pin from falling off the mounting strip of the clamp 10.

[0026] The hinged ends of the left part 2 of the firing lever and the right part 5 of the firing lever are respectively provided with hinged ears, and the stop is located on the side of the hinged ear. When in the open state, the hinged ears of the left part 2 of the firing lever and the right part 5 of the firing lever are spliced into a plate shape, and the thickness is the same as the rest of the left part 2 of the firing lever and the right part 5 of the firing lever.

[0027] Specifically:

[0028] To use, simply slide the clamp onto the barrel and push it forward until the hook on the clamp engages the barrel, securing the clamp axially and circumferentially on the barrel. Then, manually pull the trigger backward as normal to complete the installation.

[0029] A waist-shaped groove is machined at the front section of the gun tail tube to limit the axial and circumferential movement of the clamp. The clamp is designed as a cylindrical structure, and the inner hole diameter is clearance-matched with the gun tail tube. A mounting strip for installing parts such as the hook 8 and the hook spring 9 is designed above the clamp. After the clamp is installed into the gun tail tube, the hook on the clamp bounces into the waist-shaped groove on the gun tail tube under the spring force of the hook spring to realize the connection between the clamp and the gun tail tube; when disassembling, just press the handle at the tail of the hook and take it out backwards together with the clamp.

[0030] At the same time, the firing lever on the firing device is designed from one part into a structurally symmetrical left part and a right part of the firing lever. The left part and the right part of the firing lever can rotate around the lever pin 7. The left part and the right part of the firing lever are in an open state under the action of the firing lever torsion spring 6. When the clamp is installed, the left part and the right part of the firing lever are located behind the trigger 4 on the gun body. At this time, you only need to pull the trigger 4 backward normally. The rear end of the trigger 4 forces the left part and the right part of the firing lever to rotate around the lever pin until the trigger passes over the left part and the right part of the firing lever and then unfolds itself under the action of the firing lever torsion spring force, completing the installation.

[0031] The hook 8 acts on the clamp 10 through the hook shaft 11. Under the action of the hook spring 9, the tenon at the front end of the hook 8 is always in a downward state. When the clamp 10 is mounted on the breech block of the butt body 1 through the positioning hole, the tenon at the front end of the hook 8 directly enters the waist-shaped positioning groove on the butt body 1 to achieve positioning. The left part 2 of the firing lever, the right part 5 of the firing lever and the firing lever torsion spring 6 are connected to the wire rope shaft 3 through the lever pin shaft 7. When the clamp 10 is installed on the gun tail tube, the left part 2 of the firing lever and the right part 5 of the firing lever are just behind the trigger 4. When the trigger 4 is pulled backward normally, the left part 2 of the firing lever and the right part 5 of the firing lever will overcome the spring force of the firing lever torsion spring 6 and shrink inward under the action of the trigger 4 until the trigger 4 completely passes the left part 2 of the firing lever and the right part 5 of the firing lever. At this time, the left part 2 of the firing lever and the right part 5 of the firing lever return to their original position under the action of the firing lever torsion spring 6. When the trigger 4 is released, the trigger 4 returns to the front under the action of the spring force of the gun body sear spring, completing the installation of the firing device.

[0032] When disassembling, press the trigger 4 backward, and at the same time press the left part 2 of the firing lever and the right part 5 of the firing lever inward until the trigger 4 can pass through the left part 2 of the firing lever and the right part 5 of the firing lever by itself to achieve release; press down the handle at the tail of the hook 8 and pull the clamp 10 backward to achieve disassembly.

[0033] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
