Description

A kind of small-bore rim-fire cartridge magazine

Technical field

The utility model belongs to magazine field, particularly relates to a kind of small-bore rim-fire cartridge magazine.

Background technology

The function of magazine the bullet in magazine is pushed into successively to embrace bullet mouth position under the effect of magazine spring, and the bullet that gunlock promotes to embrace bullet mouth position again enters thorax.Small-bore rim-fire cartridge is plumbous bullet processed, pulls out elastic force little, and play root edge greatly, housing is thinner, and its main feature is ignition structure, does not have the independent fire in a stove before fuel is added, and primer mixture is in shell case around root edge.First press follower from embracing bullet mouth front end when conventional magazine shoots, then contact magazine rear wall at the bottom of toward pusher bullet to bullet, be easy to bullet is loosened, thus affect ammunition feed and fire accuracy.During conventional magazine ammunition feed, when bullet mouth is embraced in bullet disengaging, bullet loses constraint, and the bullet of below easily touches the bullet departing from and embrace bullet mouth, produces and pushes up bullet, large to the impact of the bullet edge fire in a stove before fuel is added, there is potential safety hazard.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, provides one to shoot convenient with ammunition feed, reliable small-bore rim-fire cartridge magazine.

The purpose of this utility model is achieved in that

A kind of small-bore rim-fire cartridge magazine, comprise magazine body, the upper end of described magazine body is provided with embraces bullet mouth, the lower end of magazine body is provided with magazine bottom, follower is provided with in the magazine of magazine body, magazine spring is provided with between described follower and described magazine bottom, under normality, follower is positioned at immediately below described armful bullet mouth, a laterally inserted axis of guide on described follower, follower can rotate along the axis of this axis of guide, magazine body left side wall is inserted at the two ends of the described axis of guide respectively, in the guide chute that right side wall is arranged with, the axis of guide can slide along two guide chutes, form the guiding to follower motion, described magazine body left side wall, longitudinal direction on right side wall is corresponding with the longitudinal direction of magazine.

Do not damage in order to ensure bullet during filling, simultaneously in ammunition feed process, when bullet mouth is embraced in bullet disengaging, auxiliary constraint is had to bullet, improve ammunition feed reliability, preferably, the upper end of described magazine body is also provided with an auxiliary guide frame for leading to bullet, described auxiliary guide frame is positioned at described dead ahead of embracing bullet mouth, leaves the space for loading bullet between auxiliary guide frame and armful bullet mouth.

In order to make bullet when embracing in bullet mouth, warhead section suffers restraints, make bullet marshalling, be easy to out bullet, when bullet mouth is embraced in bullet disengaging, the bullet and other bullets that depart from armful bullet mouth are kept apart, prevent from pushing up bullet, preferably, described auxiliary guide frame comprises left guide wall, right guide wall, described left guide wall, distance between the upper end of right guide wall is less than the external diameter of corresponding gun cartridge case, and be greater than the external diameter of corresponding gun bullet, left guide wall, distance between the lower end of right guide wall is more than or equal to the external diameter of corresponding gun cartridge case, left guide wall, the guide channel of bullet is formed between right guide wall.

In order to better lead to bullet, both bullet can be retrained, be easy to out bullet again, preferably, the forward surface of described left guide wall, right guide wall comprises facade, lower facade, and the inclined-plane be connected between facade, lower facade, left guide wall, right guide wall form angle β between inclined-plane in opposite directions, the angular range of β is 12 ° ~ 13 °.

For the ease of being loaded in magazine from front to back by shell case root edge, and make bullet warhead section in the process departing from armful bullet mouth be easy to rise, ensure that bullet enters cartridge chamber stably, preferably, the rear end face of described left guide wall, right guide wall is convex.

In order to axis of guide axial location, and be convenient to the slip of manually brought action-oriented axle, preferably, the guide chute cross section of described magazine body left and right sidewall is T-shaped, wherein, the narrower part of described guide chute and axis of guide matched in clearance, the two ends of the described axis of guide are respectively equipped with slider, described two sliders are fixed on the axis of guide respectively by screw, the wider portion of described guide chute and slider matched in clearance.

Owing to have employed technique scheme, the utility model has following beneficial effect:

1. the axis of guide coordinates with guide chute and to follower positioning and guiding, can reduce the friction between follower and magazine body, follower can be slided more glibly in the magazine of arc; Follower rotates the angle that can change with magazine magazine curved cut line direction around the axis of guide, no matter magazine magazine is interior by how many bullets, follower can ensure that each bullet is fitted all closely, the bullet angle change that energy auto-compensation brings due to the gap between magazine and bullet, ensures that bullet can be positioned at correct position by follower.

2. hand can by controlling slider sliding up and down in chute when shooting for the utility model, thus arrive the object controlling follower and slide up and down, the position of follower can be controlled when shooting, bullet is loaded bullet from auxiliary guiding position and the position of embracing in the middle of bullet mouth position, avoid bullet to extrude by external force, bullet can not be made to loosen, guarantee to shoot reliably.

3., during ammunition feed, when bullet mouth position is embraced in bullet disengaging, anterior auxiliary guide frame still play the guiding role, and bullet is tied, guarantees that bullet is not beated, and ensures that bullet enters cartridge chamber stably.

4. the upper end of auxiliary guide frame is formed and closes up, to the restricted effect of bullet, its degree of depth narrows gradually from down to up and reduces bullet rising resistance, rise favourable to bullet, when bullet mouth position is embraced in bullet disengaging, the bullet and other bullets that depart from armful bullet mouth are kept apart by auxiliary guide frame, prevent from pushing up bullet, eliminate safe hidden trouble.
