Description

Technical Field

[0001] This utility model belongs to the field of fuse insurance technology for projectile ammunition, specifically a wind energy insurance mechanism for projectile ammunition fuses. Background Technology

[0002] Currently, the safety mechanisms used in expendable ammunition fuses operate on the principle that during the ammunition's scattering, the changing environmental forces release the constraints on the mechanism's actuating components. The physical action of these components then converts into the switching action of electronic components or positions the mechanical structure in a desired state, thus fulfilling the operational requirements. Because the ammunition is located inside the ammunition magazine before scattering, the environmental forces utilized are mostly provided by the magazine itself; there are no safety mechanisms that utilize wind energy.

[0027] Example 1

[0028] Reference Figures 1-5 This embodiment provides a wind-powered safety mechanism for a projectile ammunition fuse, comprising:

[0029] The fuse body 3 has a guide groove 32, a shaft hole 33 at the bottom of the guide groove 32, a guide seat 2 in the guide groove 32, and a safety pin 1 in the shaft hole 33 connected to the guide seat 2.

[0030] The safety pin 1 includes a lower end post 13, a guide thread post 12 is provided at the top of the lower end post 13, and a top post 11 is provided at the top of the lower end post 13;

[0031] The bottom of the guide groove 32 is provided with a bottom groove 37, and the guide thread post 12 is provided in the bottom groove 37.

[0032] The length of the guide thread post 12 is greater than the depth of the bottom groove 37. Therefore, the top of the guide thread post 12 is located in the guide groove 32 and connected to the guide seat 2. The cross-sectional dimension of the guide groove 32 is greater than the cross-sectional dimension of the bottom groove 37 and greater than the cross-sectional dimension of the shaft hole 33.

[0033] The guide seat 2 has an internal thread 21 in the middle, which is connected to the guide thread post 12.

[0034] The guide seat 2 has a through hole in the middle, and the inner wall of the through hole is provided with an internal thread 21.

[0035] A sealing groove 34 is provided at the bottom of the shaft hole 33. A sealing gasket 4 and a sealing gasket fixing screw 5 are provided in the sealing groove 34. The sealing gasket fixing screw 5 is threadedly connected to the inner wall of the sealing groove 34.

[0036] The fuse body 3 has a cavity 38 at the bottom, with an intermediate post 39 inside the cavity 38, and a sealing groove 34 inside the intermediate post 39.

[0037] The intermediate column 39, sealing groove 34, shaft hole 33, and guide groove 32 are all coaxially arranged.

[0038] A turbine 6 is provided in the cavity 38. An opening groove is provided on the top of the turbine 6, and the opening groove is fitted onto the bottom of the intermediate column 39. A connecting hole 63 is provided at the bottom of the turbine 6, which communicates with the opening groove.

[0039] The bottom side of the safety pin 1 is provided with a first pin hole 14, and the side of the turbine 6 is provided with a second pin hole 62. The first pin hole 14 and the second pin hole 62 are connected by the turbine fixing pin 7.

[0040] A turbine limiting body 9 is provided at the bottom of the cavity 38. The turbine limiting body 9 includes a small end post 91 and a large end post 93. A third pin hole 92 is provided on the side of the small end post 91. A fourth pin hole 35 is provided on the side of the fuse body 3, which penetrates the cavity 38. The third pin hole 92 and the fourth pin hole 35 are connected by a process assembly pin 8.

[0041] Specifically, a wind-powered safety mechanism for a slingshot ammunition fuse includes a safety pin 1, a guide seat 2, a fuse body 3, a sealing gasket 4, a sealing gasket fixing screw 5, a turbine 6, a turbine fixing pin 7, a process assembly pin 8, and a turbine limiter 9.

[0042] The outer ring of the guide seat 2 is fixed in the guide groove 32 of the fuse body 3, and the inner ring has an internal thread 21, which cooperates with the guide thread post 12 of the safety pin 1.

[0043] The fuse body 3 is the main component of the fuse. All safety mechanisms and other mechanisms are assembled in its fixed position. The sealing gasket fixing screw 5 is fixed to the sealing gasket 4 in the sealing groove 34 by the outer ring thread.

[0044] The lower end post 13 of the safety pin 1 passes through the shaft hole 33 of the fuse body 3 and the connecting hole 63 of the turbine 6. The turbine 6 is fixed to the safety pin 1 by the turbine fixing pin 7, and they are connected as one unit. The end of the top post 11 of the safety pin 1 protrudes from the upper surface of the guide groove 32 and is connected to the firing device of the fuse, so that the firing device is in a constrained state.

[0045] The top surface of the small end post 91 of the turbine limiter 9 contacts the end face 61 of the turbine 6, and the bottom surface of the large end post 93 of the turbine limiter 9 is flush with the bottom surface 36 of the fuse body 3. The process assembly pin 8 passes through the fourth pin hole 35 of the fuse body 3 and the third pin hole 92 of the turbine limiter 9, constraining the radial and axial movement of the turbine limiter 9.

[0046] When a wind-powered safety mechanism for a projectile ammunition fuse is in the safe state, its structural position is as follows: Figure 1 As shown, the top post 11 of the safety pin 1 protrudes from the upper plane of the guide groove 32 and connects to the fuse firing device, thus constraining the firing device. When the submunition is not loaded into the magazine, the turbine limiting body 9 is constrained by the process assembly pin 8; when the submunition is loaded into the magazine, after the process assembly pin 8 is pulled out, the magazine end face 61 is flush with the bottom surface 36 of the fuse body 3 and the bottom surface of the large end post 93 of the turbine limiting body 9, constraining the turbine limiting body 9; in both cases, the top surface 91 of the small end post 91 of the turbine limiting body 9 contacts the end face 61 of the turbine 6, restricting the axial movement of the turbine 6 and keeping the wind energy safety mechanism in a safe state.

[0047] After the submunition is ejected at high speed from the magazine, it travels at high speed in the air. The turbine restraint 9, in its free state, detaches from the fuse body 3. The turbine 6 rotates under the influence of wind, and the safety pin 1, which is integrated with the turbine 6, moves downward along the axis. After the top surface of the safety pin 11 is flush with the top surface of the guide groove 32 of the fuse body 3, it disconnects from the fuse firing device, thus releasing the firing device from its restraint state. At this time, the wind energy safety mechanism of the submunition fuse is in the released state.

[0048] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
