Description

Anti-misoperation bullet blocking mechanism of magazine type shotgun and working method of anti-misoperation bullet blocking mechanism

Technical Field

The invention relates to the technical field of magazine type shotgun, in particular to a magazine type shotgun misoperation prevention bullet blocking mechanism and a working method thereof.

Background

Referring to fig. 10-12, in the prior art, after a bullet is released to a bullet supporting plate by a bullet magazine type shotgun bullet blocking mechanism, when a bullet pressing plate button is pressed by misoperation, secondary bullet is blocked between a first bullet and a bullet magazine tube, and if a gun pulling machine is used for supplying bullet, the bullet supporting plate cannot be lifted up, and the bullet supplying action cannot be completed, namely, bullet supplying faults are caused, and the fault elimination is very inconvenient and has potential safety hazards.

Fig. 11 shows a situation (top view) after the button of the bullet-blocking plate is pressed by mistake in the prior art, and the bullet-blocking plate rotates by a larger angle, so that the bullet-blocking teeth 106 release the secondary bullet. Fig. 12 is another cross-section (front view) of the secondary bullet ejecting being trapped between the primary bullet and the magazine tube, the carrier plate being unable to lift.

Detailed Description

The working principle and structure of the present invention are described in further detail with reference to the following examples and the accompanying drawings.

Referring to fig. 1 and 2, a bin type shotgun anti-misoperation bullet blocking mechanism is installed on a box body and comprises a bullet blocking plate 1, a bullet blocking plate shaft 2, a bullet blocking plate spring 3, a bin hanging lever 4 and a bin hanging lever spring 5, wherein the bullet blocking plate 1 is connected with the bin hanging lever 4 through the bullet blocking plate shaft 2, the bullet blocking plate spring 3 is installed between the bullet blocking plate 1 and the bin hanging lever 4, and the bin hanging lever spring 5 is installed in the bin hanging lever 4. When the button of the bullet blocking plate is pressed by misoperation, the bullet limiting convex hull 102 of the bullet blocking plate is propped by the outer circle of the first bullet, the bullet blocking plate 1 can only rotate by a small angle, and the bullet blocking teeth can not release the next bullet.

The bullet blocking plate 1 is provided with a bullet limiting convex hull 102, and the convex hull is limited by the bullet excircle on the bullet supporting plate when the bullet blocking plate button 101 is pressed, so that the bullet blocking teeth cannot release the next bullet, and the bullet supporting plate is not influenced to lift the bullet. The geometric parameters of the limit projection 102 and the blocking tooth 106 are critical to achieving the mechanism action. The bullet blocking plate 1 is provided with a positioning convex hull, the position of the outer side 103 of the positioning convex hull can be used for adjusting the buckling amount of bullet blocking teeth and bullets (the length of the bullet blocking teeth extending out of the bullet blocking plate), and the position of the inner side 104 of the positioning convex hull can be used for adjusting the amount of the bullet limiting convex hull 102 protruding out of the empty bin hanging lever, so that interference with the lifted bullet supporting plate yielding surface during bullet supply is avoided.

The gun barrel shooting direction is used as the front, and the opposite direction is used as the back.

Fig. 4 is a sectional view showing the bullet being caught by the bullet blocking teeth after being loaded into the bullet magazine tube 6 from the bullet inlet 109.

Fig. 5 shows the bullet-feeding front-supporting spring plate 9 lowered to a position where it is fitted to the lowest part of the transmitter stand, and fig. 6 shows another cross section (top view) of this position. At this time, the side limiting surface 111 of the spring supporting plate allows the spring clamping surface 107 to rotate anticlockwise, and the spring blocking teeth 106 lift the bullet releasing gun to the spring supporting plate.

Fig. 7 shows a bullet on the bullet supporting plate, and the secondary bullet is buckled by the bullet blocking teeth 106.

Fig. 8 shows a situation after the button of the blocking plate is pressed by mistake, at this time, the limited elastic convex hull 102 contacts with the outer cylindrical surface of the last bullet, the blocking plate can only rotate by a small angle, and the blocking teeth 106 will not release the secondary bullet. Fig. 9 is another cross section (front view) at this time.

Finally, it is noted that the above-mentioned preferred embodiments are only intended to illustrate rather than limit the invention, and that, although the invention has been described in detail by means of the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the invention as defined by the appended claims.
