Telescopic pipe type bullet supply guide mechanism and method

Abstract

The invention provides a telescopic pipe type bullet supply guide mechanism installed at the tail end of a gun barrel component. The bullet supply guide mechanism comprises a guide pipe and a guide pipe spring. The gun barrel component comprises an outer gun barrel and a chamber, a limiting face is arranged in the middle of the chamber, a chamber bullet inlet guide slope used for lining up the bullet is arranged at the tail of the chamber, the guide pipe and the guide pipe spring are arranged on the peripheral face of the chamber in a sleeving mode, the guide pipe is arranged at the tail of the chamber, the end, away from the chamber, of the guide pipe is in a horn shape and forms a guide pipe horn mouth, the guide pipe spring is arranged between the guide pipe and the limiting face of thechamber, the two ends of the guide pipe spring abut against the the guide pipe and the limiting face of the chamber respectively, and a limiting mechanism is arranged at the tail of the outer gun barrel and used for axially limiting the guide pipe. The invention further provides a telescopic pipe type bullet supply guide method. By means of the telescopic pipe type bullet supply guide mechanism and method, shotgun shells or other bullets with the bullet heads close to the size of the chamber are reliably guided, the probability of bullet ejecting faults can be remarkably reduced, normal unlocking and locking of a gunlock are not influenced, and it is ensured that the bullet supply process is smoother.

Description

technical field [0001] The invention relates to the technical field of firearms, in particular to a telescopic tube-type ammunition feeding and guiding mechanism and a guiding method. Background technique [0002] For general firearms, due to the index requirements of the weight and length of the whole gun, the adjustment range of the distance L1 and L2 between the magazine and the barrel in the structure is limited (such as figure 1 Shown), this type of bomb supply layout is not suitable for ordinary bombs (pointed bullets, such as figure 2 Shown) There is basically no problem with the bomb supply (such as image 3 shown), but for shotgun rounds or other rounds with bullets close to chamber size (such as Figure 4 Shown) may have ejection failure (such as Figure 5 shown). Contents of the invention [0003] Aiming at the defects in the prior art, the present invention provides a telescopic tube-type ammunition feeding guide mechanism and guiding method, which makes t...
