More preferably, the rear end external diameter of described breech block is greater than its leading portion external diameter, between the rear end of described breech block and the rear end of described breech, is provided with sealing ring; Described breech block is installed on the rear portion of described breech by bearing pin, described breech block can rotate around described bearing pin around self axis rotation simultaneously.
In order to make the overall structure of this air bubble compacter, described air chamber is connected by the rear portion of arc tracheae and described gun tube; As preferably, two end interfaces of described arc tracheae are 90 ° of angles each other.
For the ease of shell filling, the inwall of described gun tube back segment is provided with the spring catch for shooting location near the anterior position of described arc tracheae.
As preferably, the leading portion of described gun tube is columniform smooth bore section, and the back segment of described gun tube is that front portion is conical forcing cone section.The pipe thickness of forcing cone section is greater than the pipe thickness of smooth bore section, makes it have larger intensity, guarantees secure transmission shell.
The beneficial effects of the utility model are:
Air bubble described in the utility model adopts the structure of bullet on air chamber side, rear end, can realize rapid reloading and the transmitting of shell, and breech rear seal is reliable, and the transmitting pressure loss is minimum, whole air bubble compact conformation, easy to operate.
Accompanying drawing explanation
Fig. 1 is that front view cuts open, the front that in figure, left is gun tube in the office of quick transmitting air bubble described in the utility model;
Fig. 2 analyses and observe part to remove the enlarged drawing after air chamber, tracheae and flange in Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, quick transmitting air bubble described in the utility model comprises gun tube 1, the breech 2 of tubulose, breech block 3, arc tracheae 4 and air chamber 5, the leading portion of gun tube 1 is columniform smooth bore section, the back segment of gun tube 1 is that front portion is conical forcing cone section, between the outer circumferential walls of the forcing cone section rear end of the circumferential inner wall of breech 2 leading portions and gun tube 1, be threaded connection, between the circumferential inner wall of the outer circumferential walls of breech block 3 leading portions and breech 2 back segments, be threaded every type by disconnected, the rear end external diameter of breech block 3 is greater than its leading portion external diameter, between the rear end of the rear end of breech block 3 and breech 2, be provided with sealing ring 7, breech block 3 is installed on the rear portion of breech 2 by bearing pin (not shown in the figures, it is axially mutually vertical with breech 2 axially), breech block 3 can rotate the while around self axis and can rotate around bearing pin, air chamber 5 is connected with one end of arc tracheae 4, the other end of arc tracheae 4 is connected by flange 8 and communicates with gun tube 1 with the forcing cone section rear sidewall of gun tube 1, two end interfaces of arc tracheae 4 are 90 ° of angles each other, and the inwall of the forcing cone section of gun tube 1 is provided with the spring catch 6 for shooting location near the anterior position of arc tracheae 4.In said structure, the position being connected with gun tube 1 due to arc tracheae 4 is covered by breech 2, so mounting flange 8 on breech 2, and on breech 2 on the position of mounting flange 8 and gun tube 1 corresponding position through hole is set, thereby make arc tracheae 4 form with gun tube 1 structure communicating.
