[0006] Preferably, the front hoop is fixedly connected to the barrel via radially arranged barrel pins.
[0007] Preferably, a connecting body is provided on the rear end face of the threaded assembly cylinder, in which a locking pin is slidably fitted, a trigger is radially fixed to the rear end of the locking pin, a plurality of positioning grooves are evenly arranged circumferentially on the edge of the front hoop, the locking pin passes through the threaded assembly cylinder, and the front end of the locking pin is used to be inserted into a positioning groove on the edge of the front hoop for positioning.
[0008] Preferably, the locking pin is a stepped shaft, and a locking pin spring is sleeved on the small diameter section of the locking pin. The two ends of the locking pin spring act on the threaded assembly cylinder and the step surface of the locking pin respectively. An L-shaped guide groove is provided on the connecting body, and the trigger slides in the guide groove. When the trigger is in the front limit position, the front end of the locking pin is inserted into a positioning groove on the edge of the front hoop. When the trigger is in the rear limit position, the front end of the locking pin withdraws from the positioning groove on the edge of the front hoop.
[0009] Due to the adoption of the above technical solution, the utility model is used for quickly replacing and connecting the muzzle device of a rotary barrel weapon. The utility model has a simple structure, is easy to disassemble and assemble, and has low cost. The muzzle device can be quickly replaced by simply connecting and locking the muzzle device through threads. It has good processability, high production efficiency, and good economy. It has the following beneficial effects:
[0010] 1. The utility model has a simple structure, and the muzzle device can be quickly replaced by rotating the thread, and the operability is strong.
[0011] 2. The locking device is reliable to install and can realize the locking function without the help of tools. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] Figure 1 It is a schematic diagram of the structure of the utility model;
[0013] Figure 2 This is a schematic diagram of adding a muzzle device to the utility model;
[0014] Figure 3 It is a three-dimensional exploded schematic diagram of the utility model and the front hoop. DETAILED DESCRIPTION
[0015] The utility model is further described below in conjunction with the accompanying drawings, in which 1-threaded assembly cylinder, 2-locking pin spring, 3-locking pin, 4-trigger pin, 5-trigger, 6-muzzle device, 7-barrel, 8-barrel pin, 9-front hoop, 10-connector.
[0016] See also Figure 1-Figure 3 A quick connection mechanism for a muzzle device of a rotary barrel weapon, a front hoop is sleeved on the barrel of the rotary barrel weapon, and also includes a threaded assembly cylinder, the threaded assembly cylinder is sleeved on the front hoop, the inner hole of the threaded assembly cylinder is a step hole, the step surface of the inner hole of the threaded assembly cylinder is axially positioned on the front hoop, the large diameter section of the inner hole of the threaded assembly cylinder includes a smooth hole section and a threaded hole section, the smooth hole section is clearance-matched with the outer circumferential surface of the front hoop, and the threaded hole section is threadedly connected and fixed to the muzzle device.
[0017] A connecting body is provided on the rear end face of the threaded assembly cylinder, and a locking pin is slidably fitted in the connecting body. The rear end of the locking pin is radially fixed with a trigger through a trigger pin. A plurality of positioning grooves are evenly arranged along the circumference on the edge of the front hoop. The locking pin passes through the threaded assembly cylinder, and the front end of the locking pin is used to be inserted into a positioning groove on the edge of the front hoop for positioning.
[0018] The locking pin is a stepped shaft, and a locking pin spring is sleeved on the small diameter section of the locking pin. The two ends of the locking pin spring act on the threaded assembly tube and the locking pin step surface respectively. An L-shaped guide groove is provided on the connector, and the trigger slides in the guide groove. When the trigger is at the front limit position, the front end of the locking pin is inserted into a positioning groove on the edge of the front hoop. When the trigger is at the rear limit position, the front end of the locking pin withdraws from the positioning groove on the edge of the front hoop. Both limit positions (i.e., the longitudinal section and the transverse section of the guide groove) are provided with arc grooves, which cooperate with the locking pin for positioning.
