Description

Out-of-place safety assembly of firing structure of pocket pistol

Technical Field

The invention belongs to the technical field of firearm manufacturing, and particularly relates to an out-of-place safety component of a firing structure of a pocket pistol.

Background

The earliest Pocket pistol inventor was bronning, who developed a first Pocket Model automatic pistol based on M1903 in 1904-M1906, launched a 6.35 x 15.5mm semi-bottom edge automatic pistol (0.25 inch ACP), and officially put into production in 1906, which was successfully designed to become the "Model" and "template" for most Pocket automatic pistols later. The most widely used of the existing handgun is the GLOCK handgun, the traditional GLOCK handgun is also provided with parts with insufficient safety, but the insufficient safety design is to realize the insufficient safety function of the gunshot body by adding a tension spring, namely by the reset action of the spring force of the tension spring, the spring force of the tension spring is reduced after the tension spring is used for many times, so that the gunshot body cannot be reset, and the tension spring has the problem of poor reset stability during reset.

Disclosure of Invention

The invention aims to solve the problem that a firing structure of a firing body in a GLOCK pistol cannot be normally reset due to damage of a tension spring, and provides an out-of-place safety component with reasonable design.

In order to achieve the above purpose, the present invention adopts the following technical scheme: the invention discloses a short-in-place safety component of a firing structure of a pocket pistol, which is arranged on a pistol body and is characterized in that: the automatic trigger device comprises a locating chute which is arranged on the bottom surface of a locating side on a reciprocating passage of a firing pin for reciprocating the firing pin on a gun body, is inclined to the rear end of the gun body and is upwards, an in-place upper inclined surface at the bottom of the locating chute is matched with an in-place lower inclined surface which is arranged downwards in an inclined manner and is arranged at the top of a single firing rod when the gun body is in place in a returning manner, is matched with an in-place lower inclined surface which is arranged downwards in an inclined manner and is arranged at the top of the single firing rod when the gun body is in a returning manner, and an in-place upper pressing surface at the bottom of the single firing rod is matched with an in-place lower pressing surface at the upper part of a firing connecting rod when the gun body is in a returning manner, so that the firing connecting rod is not matched with an iron block after a trigger is triggered when the gun body is in a returning manner. When the gun is in place, the top of the single firing rod enters the positioning chute, the in-place upper inclined plane is matched with the in-place lower inclined plane, if the gun is not in place, the in-place lower inclined plane of the top of the single firing rod acts on the bottom surface of the positioning side of the reciprocating channel of the firing needle for the reciprocating operation of the firing needle on the gun body, and at the moment, the in-place upper pressing surface of the bottom of the single firing rod is matched with the in-place lower pressing surface of the upper part of the firing connecting rod to press the firing connecting rod, so that the firing connecting rod is kept in a state of not acting with a sear.

Preferably, the in-place upper inclined plane at the bottom of the positioning chute is parallel to the in-place lower inclined plane on the single-shot rod. The contact area of mutual cooperation is increased, and the safety is improved.

Preferably, the length of the in-place upper inclined plane at the bottom of the positioning chute is matched with the length of the in-place lower inclined plane. By increasing the contact area when in place, stability in use is enhanced.

Preferably, the in-place lower inclined surface and the out-of-place lower inclined surface are each disposed obliquely downward from adjacent sides of the two.

Preferably, a transition plane is provided at the intersection of the in-place lower inclined plane and the out-of-place lower inclined plane. The transition plane is arranged to increase the contact area with the gun body, and the acting force of the single-shot rod and the gun body can be enhanced due to the fact that the transition plane is arranged at a relatively high position, so that the reliability of use is further improved.

Compared with the prior art, the firing structure of the pocket pistol has the advantages that: when the gun strike body is not in place, the lower inclined surface of the top of the single-shot rod acts on the bottom surface of the positioning side of the reciprocating channel of the firing needle for the reciprocating operation of the firing needle on the gun body, and the lower pressing surface of the bottom of the single-shot rod is matched with the lower pressing surface of the upper part of the firing connecting rod to press down the firing connecting rod, so that the firing connecting rod is kept in a state of not acting with the sear.
