Background
The fuse safety refers to the performance that the fuse cannot be triggered accidentally to cause own loss in various environments such as production, storage, transportation and the like which are not required to be detonated. In order to ensure the safety of personnel and facilities of the own party, the safety design of the fuze is not neglected in the design process of the fuze and is one of the core technologies of the fuze design. The fuse safety device can be mainly divided into two parts, namely a safety mechanism and an explosion-proof mechanism.
The fuse safety mechanism needs to have good reliability and safety, and the fuse safety mechanism is required to firmly and reliably fix the protected parts under the conditions of ordinary storage, transportation and the like, so that the fuse cannot be relieved even in emergencies such as collision, overturn, even falling and the like of the shots, and the safety of the fuse is ensured; meanwhile, the safety mechanism can reliably release the safety in the process of projectile launching or flying under the preset condition, so that the fuze is in a state of waiting for launching. In fact, the above two conditions are all acting on the fuze from the outside, so to speak, they are mutually conflicting, and how to hold the fuze well is a difficult problem in designing the safety mechanism.
SUMMERY OF THE UTILITY MODEL

The fuze explosion-proof mechanism comprises a cylindrical spring, a sliding block, a lower partition plate, a positioning sleeve and a detonator sleeve, wherein a limiting hole and a detonator are arranged on the sliding block, a positioning groove is formed in the lower partition plate and used for positioning the lower partition plate and the positioning sleeve, a positioning groove is formed in the positioning sleeve and used for positioning the positioning sleeve and the shell, and an electric detonator is arranged on the detonator sleeve and staggered with the detonator on the sliding block in a service state to play an explosion-proof role; the sliding block is arranged in a sliding groove at one end of the shell, and the sliding movement direction of the sliding block is vertical to the elastic shaft. The sliding block is in plane contact with the sliding groove of the shell. The clapboard has a certain thickness, and the edge of the detonator and the edge of the detonating tube are staggered by a certain distance under the service condition of the cannonball; when the safety is relieved, the sliding block moves radially under the action of the cylindrical spring. The fuse safety mechanism comprises an inertia cylinder, a guide pin, an inertia cylinder spring and an upper partition plate; the inertia cylinder is provided with a bending groove, when the cannonball is in a service state, the inertia cylinder is inserted into the limiting hole of the sliding block, the detonating tube and the electric detonator are staggered, and the explosion-proof effect is achieved.
The guide pin is arranged on a guide structure of the inertia cylinder, and the guide pin extends into the zigzag groove to be matched with each other to control the moving path of the inertia cylinder. When the safety is relieved, the safety relieving time is prolonged by utilizing the relative movement of the inertia cylinder with the bent groove and the guide pin. The upper baffle plate is arranged at the upper end of the inertia cylinder, and a shaft is arranged on the upper baffle plate and matched with the inertia cylinder, and when the safety is relieved, the shaft guides the inertia cylinder to move axially.

The utility model has the advantages that:
1. when the cannonball is in a service state, the safety mechanism and the explosion-proof mechanism prevent the detonator from accidentally detonating the warhead. At the moment, the inertia cylinder in the safety mechanism is inserted into the sliding block limiting hole, so that the cylindrical spring is compressed, the sliding block cannot move, and the detonating tube on the sliding block is staggered with the electric detonator, so that the explosion-proof effect is achieved. In this case, even if the electric detonator is triggered, the warhead cannot be excited by the detonator. The spring slider explosion-proof mechanism is adopted, so that the structure is simple, the response is sensitive, and the safety and the reliability are realized.
2. Due to the effect of the zigzag groove, the inertia cylinder of the zigzag groove safety mechanism still needs to rotate when moving up and down due to recoil, certain friction is generated between the zigzag groove and the guide pin due to the design, the energy loss is increased, the up-and-down movement speed of the inertia cylinder is slowed down, and the inertia cylinder is required to receive larger acting force or acting time when reaching the safety position. Due to the design, when the ammunition accidentally falls, collides and other sudden conditions occur, the acting force on the inertia cylinder is not enough to remove the safety, and the ammunition can return to the original safety position immediately under the action of the thrust of the spring, so that the safety of the peacetime is guaranteed; in the event of a pre-set situation during the firing of the ammunition, the recoil is sufficiently high and the action time is sufficiently long, which is sufficient for the safety mechanism to be reliably relieved.
