Description

Launching tube with detachable cartridge chamber

Technical Field

The application relates to the technical field of firearms, in particular to the technical field of a launching tube of a weapon.

Background

The launch tube is an important component of the launcher and is the primary component that withstands the launch of the projectile. If the initial speed of the projectile is improved, the length of a launching tube needs to be properly increased, the loading amount needs to be increased, the combustion efficiency of the propellant needs to be improved, and the like. However, when the length of the launch tube is increased to a certain length, a certain resistance is brought to the projectile launching. Thus a simple way to increase the initial speed of the projectile is to change the amount of medication in the cartridge. However, the ability to change the load of a fixed shape, size cartridge is limited and a larger size cartridge may be replaced to increase the load. This means that the launch tube needs to be replaced with a launch tube having a larger volume of projectiles.

The firing tube chamber and the thread chamber of the existing projectile launcher are integrated and not detachable, the overall parameters of the projectile can be changed only by adjusting different loading quantities of the cartridge, and the adjustment range is limited.

Disclosure of Invention

Aiming at the defects of the launching tube of the projectile launcher in the prior art, the application provides the detachable launching tube.

The technical scheme of the application is as follows:

the utility model provides a can split barrel of cartridge chamber, includes cartridge chamber and line chamber, and the cartridge chamber is the body that holds the bullet of waiting to launch, and the line chamber is the barrel that the system has the rifling, and cartridge chamber external diameter front end is equipped with second cylinder and screw thread, is equipped with on the internal diameter of line chamber rear end and is equipped with first cylinder and the screw thread with the corresponding complex of cartridge chamber, and it is fixed that cartridge chamber and line chamber pass through threaded connection, and the first cylinder of line chamber rear end internal diameter is coaxial with the second cylinder of cartridge chamber.

The internal diameter of the cartridge chamber is divided into three sections which are sequentially reduced from back to front, the first section and the second section are a cone and a second cone with tapers, and the third section is a cylindrical section.

The utility model has the advantages of it is following:

compared with the traditional integral type launching tube, the structure of the launching tube has the advantages that the cartridge chamber part and the line chamber part are separated from the launching tube; the tail end of the chamber is provided with a unthreaded hole for ensuring coaxiality and an internal thread for connecting the chamber; the front end of the detachable cartridge chamber is provided with a cylindrical surface which is matched with the launching tube to ensure the coaxiality requirement and an external thread which is connected with the launching tube. The application can ensure that the requirements of different bullet types, different shapes of cartridges and different loading parameters can be met by selecting different cartridge chambers on the premise of keeping the caliber unchanged, and the compatibility of weapon equipment is improved; the firing tube thread chamber has high manufacturing cost, does not need to manufacture corresponding thread chambers one by one, saves the cost, improves the experimental efficiency and enables the experimental research to be quicker. The device is convenient to process and good in manufacturability; easy to clean and good in maintainability.
