detailed description

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the drawings. However, the constituent elements described in the following embodiments are examples at all, and it is not intended that the technical scope of the present invention be limited to them only.

[the first embodiment]

A muzzle device (muzzle device) 100 as a first embodiment of the present invention will be described with reference to FIGS. 1 to 8 . FIG. 1 is a schematic perspective view showing the outline of the muzzle part 150 and the muzzle mounting part 100 . The muzzle mounting part 100 may be any part as long as it is attached to the muzzle part 150 . For example, including the silencer (Suppressor) with noise reduction function, the flame arrester (Flash Hider) with the function of concealing sparks in real guns, the muzzle brake (Muzzle Brake) with recoil reduction function in real guns, Fully automatic tracer with the function of making light-storing BB bullets emit light, etc.

The tip portion 152 of the muzzle portion 150 has a thin-walled cylindrical shape. At a position away from the end portion 152 of the muzzle 150 by a predetermined distance, a three-leg (three lug or tri lug) specification-based three-lug (three lug or tri lug) can be used to assemble the muzzle mounting part 100 in one touch (push in and rotate 60 degrees). Each convex portion 151 is provided on the outer peripheral surface. But the present invention is not limited to the three-leg specification, as long as it is a push-in installation mechanism, it can also be two-lug or four-lug or other specifications of the transition shape.

FIG. 2 is an external view showing the detailed structure of the muzzle part 150 and the muzzle mounting part 100. As shown in FIG. The muzzle assembly part 100 is constituted, for example, by screwing together a functional part 202 having a sound-absorbing function and an adapter part 201 . In addition, the muzzle portion 150 of the present embodiment is integrally formed with a front sight 251 provided with a piece (not shown) for matching aiming. However, the present invention is not limited thereto. That is, the muzzle portion 150 may be provided separately from the front sight 251, or may be provided integrally with the outer barrel.

In a state 210 in which the muzzle part 150 is inserted into the adapter part 201 and pushed in, the outer peripheral part of the adapter part 201 is separated from the functional part 202 and comes into contact with the muzzle part 150 side. In this state, if the outer peripheral portion of the adapter part 201 is rotated by a predetermined angle (here, 60 degrees) and released, the adapter part 201 returns to the functional part 202 side, and the muzzle assembly part 100 is firmly fixed to the muzzle. State 220 of part 150.

FIG. 3 is a cross-sectional view showing the internal structure of the muzzle part 150 and the muzzle mounting part 100. As shown in FIG. The adapter part 201 of the muzzle mounting part 100 includes a cylindrical part 301, a cylindrical part 302, and a spring 303 as a biasing member.

The cylindrical part 302 is in contact with the muzzle part 150 and contributes to the positioning of the functional part 202 . The cylindrical part 301 is slidable relative to the cylindrical part 302, and can be fitted into the muzzle part 150 via a locking mechanism. The spring 303 urges the cylindrical part 302 toward the cylindrical part 301, so that the protrusion 151 of the locking mechanism and the cylindrical part 301 are fixed in an engaged state.

In front of the cylindrical part 302 (radiation direction), a thread 321 for threaded engagement with the functional part 202 is provided. In addition, here, the structure in which the functional part 202 and the cylindrical part 302 are screwed has been described, but the present invention is not limited thereto, and the functional part 202 and the cylindrical part 302 may be bonded or pin-fixed. In addition, the functional part 202 and the cylindrical part 302 may also be integrally formed.

The cylindrical part 301 constitutes the outer peripheral portion of the adapter part 201, and is provided with an accommodating part 311 for accommodating the cylindrical part 302 and the spring 303, a sealing part 312 for sealing the opening on the front side (radiation direction side) of the accommodating part 311, Fix the sealing part 312 to the threaded part 313 of the receiving part 311 .

The cylindrical part 302 is housed inside the cylindrical part 301 so as to be slidable in the front-rear direction (direction along the axis of the muzzle).

The cylindrical part 302 is in contact with the end of the spring 303 on the shooter side, and is biased backward (in the direction of the shooter) by the spring 303 . Thereby, the end surface 322 of the cylindrical part 302 on the side opposite to the thread 321 abuts against the abutting surface 314 provided inside the housing member 311 .

4 is a view from the muzzle side showing a state in which the muzzle 150 is inserted into the rear side opening 315 of the cylindrical part 301, and further the cylindrical part 301 is separated from the functional part 202 to apply force to the rear (shooter direction). Observed front view 401 and A-A sectional view 402 . By biasing the cylindrical part 301 toward the shooter side (gun body side) against the urging force of the spring 303 , the end surface 322 is separated from the contact surface 314 . Since the cylindrical elastic part 421 is attached to the inner surface of the cylindrical part 302 , it can be inserted into the inside of the cylindrical part 302 without damaging the distal end part 152 of the muzzle part 150 .

Fig. 5 is a front view 501 viewed from the muzzle side, showing a state in which the cylindrical part 301 is further urged toward the muzzle portion 150 side from the state of Fig. 4 and rotated counterclockwise by 60 degrees as viewed from the muzzle side. And A-A sectional view 502. By rotating 60 degrees, the claw 516 provided on the cylindrical part 301 faces a position on the rear side (shooter side) of the convex part 151 .

Fig. 6 is a slave gun showing a state where the cylindrical part 301 moves forward (in the firing direction) due to the elastic force of the spring 303 and abuts against the functional part 202 when the hand is separated from the cylindrical part 301 in the state of Fig. 5 Front view 601 and A-A sectional view 602 viewed from the oral side.

The claw 516 abuts against the convex portion 151 , whereby the muzzle fitting 100 is firmly fixed to the muzzle portion 150 .

In addition, at this time, the outer peripheral surface of the distal end portion 152 of the muzzle portion 150 is firmly held and positioned by the inner peripheral surface 621 of the cylindrical part 302 . On the other hand, the outer peripheral surface of the convex portion 151 of the muzzle portion 150 is also firmly held and positioned by the inner peripheral surface 622 of the cylindrical component 302 .

As a result, with respect to the muzzle part 150, the cylindrical part 302 is very accurately positioned avoiding the accumulation of dimensional tolerances, and as a result, the functional part 202 threadedly engaged with the thread 321 of the cylindrical part 302 is also positioned without regard to the muzzle part 150. I attach it precisely without shaking and can center it.

Fig. 7 is a diagram showing changes in the B-B sectional view of Fig. 2 . It can be seen that the structure facing the protrusion 151 of the muzzle changes from the notch 701 to the claw 516 as the cylindrical part 301 rotates. That is, when the muzzle part 150 is inserted into the muzzle assembly part 100, the three protrusions 151 are inserted into the three cutouts 701, and after that, if the adapter part 201 is pushed into the muzzle part 150 side and rotated, the three claws 516 is locked so as to face the three protrusions 151 .

The cylindrical component 301 includes three stoppers 702 axially extending from the inner peripheral surface. The convex part 151 abuts against the stopper part 702, whereby the rotation of the cylindrical part 301 (counterclockwise rotation during assembly, clockwise rotation during detachment) can be restricted within a certain range. It is possible to prevent unreliable loading and unloading operations from turning over during rotation. The stopper portion 702 is not an essential structure, and as shown in FIG. 8 , a structure without the stopper portion 702 may be used. In this case, it is possible to rotate in any direction when assembling or detaching.

Therefore, the functionality that the muzzle mounting part 100 can be easily attached and detached can be maintained, and the muzzle mounting part 100 can also be mounted on the muzzle part 150 without shaking. The firing accuracy of the BB bullet fired by the unit 150 is maintained at a high level. By further improving the firing accuracy, it is possible to prevent bullets from colliding with internal mechanisms and damage to functional parts and BB bullets.
