Embodiment Construction

[0026] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] In order to solve the problems of the prior art, the present invention provides a segmented barrel connection structure, which includes: a sealing ring 3, a spiral ring 4, and a set screw 5;

[0028] The cross-section of the sealing ring 3 is triangular, and it is sleeved on the connecting end faces of the front body tube 1 and the rear body tube 2. A cone angle of the triangle structure is aligned with the connection part, and the two cone surfaces of the cone angle are close to the front body tube. The pipe 1 and the rear section of the body pipe 2 are connected to the end surface, and the surface corresponding to the opposite direction of the taper angle is facing outward;

[0029] The specific assembly seque...

Abstract

The invention belongs to the technical field of gun design and in particular relates to a segmented type barrel connecting structure for connecting two segmentations of barrels of a gun. In the structure, connection is carried out through whorls and nuts; obturation is carried out by using a sealing ring with the cross section to be triangular; and in addition, set screws are adopted to prevent rotation. According to the structure disclosed by the invention, as being arranged on the inner sides of the barrels, the sealing ring expands outwards under the action of gun pressure during shooting, the conical surfaces are better in cling, and sealing is more reliable; meanwhile, gunpowder gas cannot enter an interval between the end surfaces of the two segmentations of the barrels, so that the connecting part only needs to bear the inertia force of a back seat without bearing the gun pressure, and the axial stress is weak; and as the whorls are connected to form a whole body, the stress state is better, and the connecting structure is compact.

Description

technical field [0001] The invention belongs to the technical field of artillery design, and in particular relates to a segmented barrel connection structure, which is used for the connection between two sections of barrels of artillery. Background technique [0002] Known a segmented barrel connection structure such as figure 1 As shown: a boss is reserved at the joint between the front barrel 1 and the rear barrel 2, and then the connection is made through the flange 4, and a circle of bolts 5 is used to fasten the two sections of the barrel, and at the same time ensure that the two sections of the barrel The sealing ring 3 between them is compressed to hold air. [0003] to combine figure 1 It can be seen that in order to ensure that the sealing ring 3 has sufficient pre-pressure to effectively hold the air, there must be a gap between the end faces of the two barrels. When shooting, the gunpowder gas entering the gap between the end faces will generate a relatively lar...
