Description

Technical Field

[0001] This utility model belongs to the field of fuse safety technology, specifically a contact sealing safety mechanism. Background Technology

[0002] The safety mechanism used in ammunition scattering fuses works by releasing the constraints of the safety mechanism's moving parts during the ammunition scattering process, under the influence of changing environmental forces. The physical action of the moving parts is then converted into the switching action of electronic components or to bring the mechanical structure to a certain required state, thus meeting the usage requirements. Generally, safety mechanisms that release conditions through pull-out or inertia are used, and they require a certain amount of time to act. Utility Model Content

[0024] Example 1

[0025] Reference Figures 1-5 This embodiment provides a contact sealing safety mechanism, including,

[0026] The fuse body 3 has a safety pin cavity 33 and a sealing cavity 34. The safety pin cavity 33 has a safety pin 1, the sealing cavity 34 has a sealing cap 4 at the top, a gasket 5 under the sealing cap 4, and a sealing screw 6 in the sealing cavity 34.

[0027] The safety pin cavity 33 and the sealing cavity 34 are connected. The size of the sealing cavity 34 is larger than that of the safety pin cavity 33. The sealing screw 6 is threadedly connected to the sealing cavity 34 (the thread is not shown in the figure). The sealing screw 6 compresses the gasket 5 and the sealing cap 4 to form a seal.

[0028] The top of the safety pin cavity 33 is provided with a perforation for the safety pin 1 to pass through.

[0029] The safety pin 1 includes a top post 12 and a step plate 13 disposed on the top post 12, and a safety pin cap 11 is disposed on the top of the safety pin 1.

[0030] A safety pin spring 2 is fitted on the top column 12, and the safety pin spring 2 connects the top surface of the step plate 13 and the safety pin cavity 33.

[0031] The fuse body 3 also has a bottom cavity 37, and the fuse body 3 has a first pin hole 35 on its side.

[0032] A bottom limiting body 9 is provided in the bottom cavity 37, an inner cavity 92 is provided in the bottom limiting body 9, an inner post 91 is provided in the inner cavity 92, and a second pin hole 94 is provided through the bottom limiting body 9 from the side.

[0033] It also includes process assembly pin 8, which is set through the first pin hole 35 and the second pin hole 94.

[0034] A conical spring 7 is provided in the inner cavity 92. The small end face of the conical spring 7 contacts the inner cavity end face 93 of the bottom limiting body 9, and the large end face of the conical spring 7 contacts the bottom end face of the sealing screw 6.

[0035] This embodiment discloses a contact sealing safety mechanism, including a safety pin 1, a safety pin spring 2, a fuse body 3, a sealing cap 4, a gasket 5, a sealing screw 6, a conical spring 7, a bottom limit body 9, and a process assembly pin 8.

[0036] The sealing cap 4 and gasket 5 are threadedly locked into the sealing cavity 34 of the fuse body 3 by the sealing screw 6, keeping the fuse body 3 sealed in both the locked and unlocked states. The conical spring 7 is compressed and constrained in the inner cavity 92 of the bottom limiting body 9. The small end face of the conical spring 7 contacts the inner cavity end face 93 of the bottom limiting body 9, and the large end face of the conical spring 7 contacts the bottom end face of the sealing screw 6. The large end face 95 of the bottom limiting body 9 is flush with the bottom surface 36 of the fuse body 3. The process assembly pin 8 passes through the first pin hole 35 of the fuse body 3 and the second pin hole 94 of the bottom limiting body 9, constraining the axial movement of the bottom limiting body 9. The inner post 91 of the bottom limiting body 9 contacts the outer end face of the sealing cap 4, causing the sealing cap 4 to be in a deformed state.

[0037] The safety pin 1 is installed in the safety pin cavity 33 of the fuse body 3. The bottom end face 14 of the fuse body 3 contacts the inner end face of the sealing cap 4 and is constrained by it to prevent vertical downward movement. The stepped plate 13 of the safety pin 1 contacts one end face of the safety pin spring 2 and compresses the safety pin spring 2, so that the other end face of the safety pin spring 2 contacts the top surface 32 of the safety pin cavity of the fuse body 3. The safety pin cap 11 of the safety pin 1 protrudes from the upper surface 31 of the safety pin cavity 33 and is connected to the fuse firing device, so that the firing device is in a constrained state.

[0038] Specifically, when a contact seal safety mechanism is in the safe state, its structural position is as follows: Figure 1As shown, the safety pin cap 11 of the safety pin 1 protrudes from the upper plane 31 of the safety pin cavity 33 and connects to the fuse firing device, thus restraining the firing device. When the ammunition is not loaded into the magazine, the bottom limiting body 9 is restrained by the process assembly pin 8; when the ammunition is loaded into the magazine, after the process assembly pin 8 is pulled out, the magazine end face (not shown in the magazine diagram) is flush with the bottom surface 36 of the fuse body 3 and the large end face 95 of the bottom limiting body 9, restraining the bottom limiting body 9; in both cases, the inner post 91 of the bottom limiting body 9 contacts the outer end face of the sealing cap 4, ultimately restricting the axial downward movement of the safety pin 1, thus putting the contact sealing safety mechanism in a safe state.

[0039] When the ammunition is ejected at high speed from the magazine, the bottom surface 36 of the ammunition fuse body 3 instantly disengages from the magazine. Under the combined elastic force of the safety pin spring 2 and the conical spring 7, the bottom limiting body 9 is ejected, releasing the constraint of the bottom limiting body 9 on the safety pin 1. Under the elastic force of the safety pin spring 2, the safety pin 1 moves freely downwards. After the top plane of the safety pin cap 11 of the safety pin 1 is flush with the upper plane 31 of the safety pin cavity (the sealing cap 4 returns to its original state), it disconnects from the fuse firing device, releasing the firing device from its constrained state. At this time, the ammunition ejection fuse contact sealing safety mechanism is in the released state, and its structural position is as follows: Figure 2 As shown.

[0040] 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.

[0041] 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.
