Embodiment Construction

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

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

[0028] The sealing ring 3 has a triangular cross-section, and is sleeved on the connecting end surface of the front body tube 1 and the rear body tube 2. A cone angle of the triangular structure is aligned with the connection part, and the two cone surfaces of the cone angle are close to the front body 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 cone angle faces the outside;

[0029] The specific assembly sequence of the connection struc...

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 particularly relates to a segmented barrel connection structure, which is used for the connection between two sections of the artillery barrel. Background technique [0002] A segmented body tube connection structure is known as figure 1 Shown: a boss is reserved at the connection of the front section of the body tube 1 and the rear section of the body tube 2, and then the flange 4 is used to connect the two sections of body tube with a circle of bolts 5, while ensuring that the two sections of body tube are connected The sealing ring 3 between is pressed tightly to close the air. [0003] Combine figure 1 It can be seen that in order to ensure that the sealing ring 3 can have sufficient pre-pressure for effective air closure, there must be a gap between the end faces of the two sections of the body tube. When the gunpowder gas enters the gap between the end faces, a greater axial pressure ...
