Impact-detonation fuse structure

Abstract

This invention provides a contact-detonation fuse structure, comprising a lower shell, an inner assembly, and an upper shell. The lower shell has a lower shell accommodating space and a safety backup assembly is disposed therein. The inner assembly is disposed within the lower shell accommodating space and contains an initial explosive charge and a detonating explosive charge. A connecting channel and at least one linkage explosive charge are provided between the initial explosive charge and the detonating explosive charge. The upper shell assembles the lower shell, sleeves the inner assembly, and provides a firing pin. An upper cover is provided above the firing pin to contact the firing pin. The inner assembly can control the connecting channel to connect the initial explosive charge and the detonating explosive charge, and control the linkage explosive charge to connect the initial explosive charge and the detonating explosive charge, thereby achieving the effect of switching between an immediate detonation mode and a delayed detonation mode.

Claims

1. A contact-detonation fuse structure, comprising: The system comprises: a lower shell containing a lower shell accommodating space, within which a safety reserve assembly is disposed; an inner assembly disposed within the lower shell accommodating space, containing an initial explosive charge and a detonating explosive charge, and having a connecting channel and at least one linkage explosive charge between the initial explosive charge and the detonating explosive charge; and an upper shell assembled on the lower shell and fitted with the inner assembly, having a top cover on the upper shell, and having a firing pin disposed above the initial explosive charge inside the upper shell, the top of the firing pin contacting the top cover, and the inner assembly controlling the connecting channel to connect the initial explosive charge and the detonating explosive charge, and controlling the linkage explosive charge to connect the initial explosive charge and the detonating explosive charge.

2. The impact fuse structure as described in claim 1, wherein at least one lower shell assembly is formed on the side of the lower shell, and at least one upper shell assembly is formed on the side of the upper shell, the lower shell assembly and the upper shell assembly are assembled together by an assembly, such that the upper shell is disposed above the lower shell.

3. The impact fuse structure as described in claim 1, wherein the top of the lower housing has at least one connector, and the bottom of the upper housing has at least one upper housing bottom groove, the upper housing being assembled with the upper housing bottom groove and the connector to securely mount the upper housing above the lower housing.

4. The impact fuse structure as described in claim 1, wherein an outer assembly is formed on the side of the upper housing, and an inner assembly is formed on the upper cover and is configured to interact with the outer assembly.

5. The impact fuse structure as described in claim 1, wherein the inner body has a control component, the control component is connected to a linkage component via the upper housing, and the linkage channel and the linkage charge are disposed within the linkage component, so that the linkage component is rotated under the control of the control component, thereby controlling the linkage channel to connect the initial charge and the detonating charge, and controlling the linkage charge to connect the initial charge and the detonating charge.

6. The impact fuse structure as described in claim 5, wherein a top rib is formed on the top of the control assembly, and the firing pin is mounted on the top rib.

7. The impact fuse structure as described in claim 1, wherein at least one support pin is provided through the side of the upper housing, the support pin passing through the upper housing and inserted into the firing pin.

8. The impact fuse structure as described in claim 1, wherein an upper shell channel is formed inside the upper shell, and the firing pin is disposed above the initial propellant charge through the upper shell channel.

9. The impact fuse structure as described in claim 8, wherein the firing pin side is formed with at least one side top rib that contacts the inner wall of the upper shell channel.

10. The impact fuse structure as described in claim 9, wherein the top of the firing pin has a top arc portion, and the firing pin contacts the inner wall of the upper cover from the top arc portion, and a side arc portion is formed on the side of the firing pin, the side arc portion being formed between the side top rib and the top arc portion.

11. The impact fuse structure as described in claim 4, wherein the upper cover side has at least one deformable sidewall formed above the inner assembly.

12. The impact fuse structure as described in claim 5, wherein the lower housing has at least one limiting member contacting the control component.

13. The impact fuse structure as described in claim 5, wherein at least one abutment is formed on the side of the linkage component, the abutment contacting the inner wall of the inner component.
