Embodiment 1
[0022] combine figure 1 and figure 2 , a sequence ball partition type low recoil safety mechanism, the external dimensions are length 14 mm × width 9 mm × height 21 mm, including gasket (1), second spring (3), body (4), safety lever (5) , an annular cover plate (6), an isolation block (9), a sleeve (10), a first spring (11), a washer (12) and seven safety balls (8). The body (4) is spliced by two symmetrical half bodies, positioned by the positioning pin (2) and fastened by the connecting screw (7). The body (4) is provided with a first vertical channel, a second channel and a third channel in parallel and spaced in sequence, and a fourth channel along the horizontal direction and vertically communicating with the second channel is also provided in the body (4). Wherein, the first channel extends downward from the top of the body (4), the second channel and the third channel both extend upward from the bottom of the body (4), and the length of the second channel is greate...

The invention discloses a sequential ball partition type low blowback safety mechanism structure. Under the action of low emission overload, a separation block receives smaller inertia force, and thedeformation of a second spring is also smaller, so that safety balls can penetrate through through holes in the separation block under the thrust action of blowback force to further enable a safety lever to arming; and under the large overload action of falling impact, the separation block receives larger inertia force, and the deformation of the second spring is also larger, so that the separation block moves downwards to enable the through hole to move downwards, and the separation block prevents the safety balls from moving to further ensure reliable safety. The sequential ball partition type low blowback safety mechanism structure is simple and occupies smaller space; the maximum outline size is 14mm (length) *9mm (width)*21mm (height); the sequential ball partition type low blowbacksafety mechanism structure has mechanism flexibility and reliability checking function, can identify 4g extremely low emission overload environment and can realize reliable safety when a fuse falls toa hard target and a soft target with any angle.
Description
technical field [0001] The invention relates to the field of fuzes, in particular to a sequence ball partition type low recoil safety mechanism. Background technique [0002] In the process of mining, blasting is often used. The used rocket has a safe and reliable fuze device that is directly related to the life safety of the miners. In the past, fire detonators and starting paper cannons were used as detonation fuzes in mining rockets, which had disadvantages such as difficult installation, easy to be affected by moisture, poor sensitivity, and poor safety performance. Chinese patents 94219958.8 and 02246531.6 all improved the fuze of mining rockets, mainly solving the problem of self-destruction of the fuze. However, there is insufficient research on the safety and disarming devices of rocket fuzes. [0003] Mining rockets fly at low speed and do not rotate. The recoil environment of the fuze is the main environment for the design of its insurance mechanism. The reliabi...
