In this embodiment, the inside diameter of the pilot tube flare 3 is larger than the outside diameter of the cartridge chamber inlet pilot ramp 5. Making it easier for the cartridges 2 in the magazine 1 to be introduced into the chamber 6.
In this embodiment, the outer barrel 9 and the cartridge chamber 6 are fixedly connected together by a combination of the connecting pin 10 and the interference fit, and other fastening means such as threads may be used.
In this embodiment, the guide tube 4 is axially limited by a limiting mechanism on the outer barrel 9, and the limiting mechanism adopts a form of a connecting screw 7 or a limiting pin, etc.
As shown in fig. 7a, 7b and 7c, the present invention further provides a telescopic tube type bullet feeding guiding method, which guides a bullet by using a telescopic tube type bullet feeding guiding mechanism as described above, comprising the following steps:
step 1, the gun camera is reworked, and a bullet in the bullet pushing box firstly enters a guide tube;
step 2, the bullet is guided by the horn mouth of the guide tube and then continuously moves forwards, and at the moment, the head of the bullet is contacted with the guide inclined plane of the bullet inlet of the bullet chamber;
step 3, under the combined action of the guide tube and the guide inclined plane of the bullet inlet of the bullet chamber, the bullet is regulated;
and 4, continuing to advance the gun stock and simultaneously pressing the guide tube to compress the guide tube spring, and completely entering the cartridge chamber after the guide tube spring is completely compressed to finish the bullet guiding.
The design principle of the invention is as follows:
as shown in FIG. 8, the shotgun shell is guided by conventional feed, and the force applied (neglecting friction) during normal loading of the shell is related to O 1 The moment equation for a point is:
M O1 ＝F 1 a 1 +F spring a 2
Wherein: f (F) 1 a 1 -represent F 1 For O 1 The moment of the point, anticlockwise in direction, has a value of "+",
F spring a 2 -represent F Spring For O 1 The moment of the point, the direction anticlockwise, has a value of "+".
So MO1 > 0, the direction is counter-clockwise, this moment forces the tail end of the bullet downwards, the center of the bullet will deviate from the center line of the barrel, contrary to the relation that requires that the center line of the bullet should be gradually close to and coincide with the center line of the barrel during the feeding process, the ejection failure must occur during the feeding process.
As shown in FIG. 9, the force applied (neglecting friction) during the normal loading of the bullet, with respect to O, is applied to the shotgun shell by the inventive bullet-feeding guidance method 2 The moment equation for a point is:
M O2 ＝F 1 b 1 +F spring b 2
Wherein: f (F) 1 b 1 -represent F 1 For O 2 The moment of the point, clockwise in direction, has a value of "-",
F spring b 2 -represent F Spring For O 2 The moment of the point, the direction anticlockwise, has a value of "+".
F can be made by parameter design 1 b 1 Absolute value is greater than F Spring b 2 Absolute value of M at this time O2 The direction is clockwise less than 0, the moment forces the tail end of the gun to lift closer to the center line of the gun barrel, and the gun is gradually regulated, so that the feeding of the gun can be smooth.
The invention can realize reliable guidance to the supply of shotgun shell or other bullet with small difference between the diameter of bullet and the size of bullet chamber, and can obviously reduce the probability of ejection failure. The guide tube is telescopic under the spring force of the guide tube spring, and is used for guiding the bullet feeding of the bullet during bullet feeding, and the guide tube can be pressed down by a gun camera after the bullet enters the bore, so that locking is not influenced, and the reliable action of the mechanism can be ensured.
