Description

Technical Field

[0001] The utility model relates to the technical field of shooting training auxiliary equipment, in particular to a device capable of realizing continuous shooting of machine gun blank cartridges. Background Art

[0002] In actual tactical training, due to the high cost and certain risks of using live ammunition, and in order to enable trainees to truly experience the vibration, sound and light of shooting, blank bullets are often used instead of live ammunition. Blank bullets refer to bullets with only a shell, a small amount of powder, and a primer. They are usually used for training and exercises, and have the sound, light, smoke and flame effects of simulating live ammunition shooting.

[0003] However, when machine guns currently use blank ammunition for training shooting, since blank ammunition has no live bullet, but only a cartridge case, a small amount of charge and a primer bullet, the resistance cannot quickly form sufficient chamber pressure, resulting in serious cartridge jamming. In addition, the gunpowder gas cannot reach the standard of compressing the return spring, and the bolt frame cannot reach the standby state, resulting in the machine gun being unable to achieve continuous firing of blank ammunition, affecting the firing frequency.

[0004] In the prior art, in order to trigger the laser firing simulator simultaneously with the blank bullet when firing the laser, the sound, vibration or muzzle flame of the blank bullet is generally collected as a signal to trigger the laser firing simulator to fire; however, the sensors for collecting the above signals have the following disadvantages that are not easy to overcome: the signal is not easy to extract, it is difficult to distinguish the sounds of adjacent guns, the sensor is expensive, and the stability is poor.

[0005] Therefore, a device for realizing continuous firing of machine gun blank cartridges is proposed to solve the existing shortcomings. Utility Model Content

[0007] In order to solve the above technical problems, the technical solution provided by the utility model is a device capable of realizing continuous shooting of machine gun blank cartridges: comprising a gas-blocking rod, a sleeve and a barrel locking buckle;

[0008] The air-blocking rod comprises a knob, a threaded seat and a blocking rod which are coaxially arranged from front to back in sequence, an air guide hole is arranged in the blocking rod, and a through hole connected to the air guide hole is arranged in the circumference of the knob;

[0009] The barrel locking buckle is connected to the sleeve, the barrel locking buckle adopts a double semi-circular embracing structure, and the barrel locking buckle is fixed to the barrel of the gun by screws;

[0010] The blocking rod is coaxially arranged in the casing and is threadedly connected with the casing through a threaded seat.

[0011] As an improvement, the knob, the threaded seat and the blocking rod are integrally formed.

[0012] As an improvement, the sleeve is a hollow cylindrical structure, and a side opening is provided in the circumference of the sleeve.

[0013] As an improvement, the barrel locking buckle includes a locking piece and a pressing piece, the pressing piece is fixedly connected to the sleeve, one side of the locking piece is connected to the pressing piece by a hinge, and the other side of the locking piece is connected to the pressing piece by a screw.

[0014] The advantages of the utility model compared with the prior art are:

[0015] 1. Through the coordinated arrangement of the gas-blocking rod and the sleeve, the sealing coordination between the blocking rod and the barrel can be achieved, so as to increase the chamber pressure in the barrel, thereby increasing the recoil energy of the barrel, so that the cartridge case automatically separates from the barrel, assisting the machine gun to complete the automatic action, thereby enabling the machine gun to achieve the purpose of continuous shooting of blank cartridges;

[0016] 2. The device has a simple structure, is easy to manufacture, easy and firm to install, and is safe and reliable to use. It can prevent the machine gun from having a jamming phenomenon of the ammunition belt during the continuous shooting of blank cartridges, greatly improving the safety of machine gun blank cartridge shooting training and further improving the quality and effectiveness of training.

[0028] Combined with Figure 1-5 As shown, a device for realizing continuous shooting of blank cartridges of a machine gun comprises a gas-blocking rod 1, a sleeve 2 and a barrel locking buckle 3;

[0029] The air-blocking rod 1 includes a knob 11, a threaded seat 12 and a blocking rod 13 which are coaxially arranged from front to back. In a specific implementation, the knob 11, the threaded seat 12 and the blocking rod 13 are integrally formed.

[0030] During implementation, the air-blocking rod 1 is coaxially arranged with the sleeve 2, and the air-blocking rod 1 is threadedly connected with the sleeve 2 via a threaded seat 12. Specifically, the threaded connection between the threaded seat 12 and the sleeve 2 can be achieved by rotating the knob 11, and a firm connection between the air-blocking rod 1 and the sleeve 2 is ensured.

[0031] The blocking rod 13 is provided with an air guide hole 14, and the knob 11 is circumferentially provided with a through hole 15 connected to the air guide hole 14. When blank ammunition is fired, part of the smoke and flame of the blank ammunition emerges through the air guide hole 14 of the blocking rod 13 and the through hole 15 of the knob 11, so that the fireworks during live ammunition shooting can be simulated. At the same time, during the blank ammunition shooting process, foreign matter generated during the blank ammunition shooting process can be received through the air guide hole 14 and the through hole 15, thereby reducing damage to the gun barrel.

[0032] The barrel locking buckle 3 is connected to the sleeve 2. Specifically, the sleeve 2 is a hollow cylindrical structure, and a side opening 5 is provided in the circumference of the sleeve 2.

[0033] The barrel locking buckle 3 adopts a double semi-circular embracing structure, and the barrel locking buckle 3 is fixed to the barrel of the gun by means of screws 4;

[0034] Furthermore, the barrel locking buckle 3 includes a locking member 31 and a pressing member 32, and the pressing member 32 is fixedly connected to the sleeve 2. One side of the locking member 31 is connected to the pressing member 32 through a hinge, and the other side is connected to the pressing member 32 through a screw 4.

[0035] In a specific implementation, the fixed connection between the barrel locking buckle 3 and the barrel can be achieved, thereby ensuring the fixed connection between the sleeve 2 and the barrel, and thus ensuring the fixed connection between the device and the barrel;

[0036] At the same time, during the implementation process, in order to prevent the vibration during the shooting of the machine gun from causing the device and the gun barrel to become loose, a copper gasket can be installed between the locking piece 31 and the gun barrel to make the connection between the device and the gun barrel more secure.

[0037] The blocking rod 13 is coaxially arranged in the sleeve 2 and is threadedly connected to the sleeve 2 through the threaded seat 12. Specifically, the diameter of the blocking rod 13 is smaller than the inner diameter of the sleeve 2 and is adapted to the inner diameter of the gun barrel.

[0038] In the specific implementation of the utility model, before shooting, one end of the sleeve 2 is installed at the muzzle fire cap position, and the pressing piece 32 is matched with the barrel, and then the locking piece 31 and the pressing piece 32 are fixedly installed with the screw 4 to realize the fixing of the sleeve 2 and the barrel;

[0039] Secondly, insert the gas-blocking rod 1 into the sleeve 2, and insert the end of the blocking rod 13 into the fire cap to seal the muzzle of the gun barrel, and then rotate the knob 11 to tighten it with the sleeve 2 through the threaded seat 12 to achieve a fixed connection between the device and the gun barrel;

[0040] During shooting, due to the small diameter of the gas hole 14, a small amount of smoke can be emitted through the gas hole 14 and the through hole 15. While simulating the fireworks during live ammunition shooting, it can prevent the gunpowder gas in the barrel from flowing out of the muzzle too much, thereby increasing the chamber pressure in the barrel, and then increasing the recoil energy of the barrel, so that the cartridge case automatically detaches from the barrel, assisting the machine gun to complete the automatic action, so that the machine gun can realize continuous shooting of blank cartridges.

[0041] At the same time, when the device is working, foreign matter generated during the shooting of blank bullets can be received through the air guide hole 14 and the through hole 15, thereby reducing damage to the gun barrel.

[0042] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
