DETAILED DESCRIPTION

[0022] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1-4 As shown, one embodiment of the present invention provides a self-destructible multi-purpose fuze device, comprising a base 1, an elastic device 2 providing reciprocating power, a movable member 4 provided with contacts (not shown in the figure), a battery 5, a waterproof protective shell 6, and a safety assembly 7. The elastic device 2 and one end of the movable member 4 are provided on the outer surface of the base 1 as the front end, the battery 5 is provided in a groove at the rear end of the base 1, the protective shell 6 is provided on the outside of the base 1, and the safety assembly 7 is provided on the outer surface of the protective shell 6;

[0024] A first limiting member 101 is provided at the upper right of the front end surface of the base 1 , and the movable member 4 is slidably provided inside the first limiting member 101 ; a second limiting member 102 is provided at the lower right of the front end surface of the base 1 .

[0025] In this embodiment, the elastic device 2 is used to provide a rebound force to the movable part 4. When the movable part 4 is subjected to pressure from above the first limit part 101 or tension from below the second limit part 102, and the force is greater than the force provided by the elastic device 2, the movable part 4 moves toward the second limit part 102. When the external force is removed, the force provided by the elastic device 2 can reset the movable part 4.

[0026] In one embodiment, the elastic device 2 includes a fixing clamp 201, a spring bar 202, and a steering column 203; the steering column 203 is arranged at the right side of the middle position of the front end surface of the base 1, one end of the fixing clamp 201 is close to the second limit member 102, and the other end is close to the steering column 203, one end of the spring bar 202 is fixedly installed in the middle of the fixing clamp 201, and the other end of the spring bar 202 passes around the steering column 203 and is fixedly connected to the movable part 4.

[0027] In this embodiment, the fixing clamp 201 fixes one end of the spring bar 202 . When the movable member 4 moves due to an external force, the spring bar 202 can provide a force to quickly reset the movable member 4 .

[0028] In one embodiment, a pressure rod 3 is installed at the end of the movable part 4 near the first limiting part 101, and a pulling hole 401 is provided at the end of the movable part 4 near the second limiting part 102; a slot is provided between the pressure rod 3 and the pulling hole 401, and the movable part 4 is electrically connected to the spring bar 202 through a first contact (not shown in the figure) in the slot.

[0029] In this embodiment, the pressure rod 3 is threadedly connected to the top of the movable part 4, and the movable part 4 can be pressed by the pressure rod 3; and a pulling rope is tied to the pulling hole 401, and the movable part 4 can be pulled by the pulling rope passing through the second limiting part 102.

[0030] In one embodiment, a first electrode 501 and a second electrode 502 are disposed between the movable member 4 and the steering column 203 , a resistor 503 is electrically connected between the first electrode 501 and the second electrode 502 , and the spring bar 202 is disposed between the first electrode 501 and the second electrode 502 .

[0031] In this embodiment, the first electrode 501 and the second electrode 502 are electrically connected to the positive and negative poles of the battery 5, respectively. When the movable part 4 is only subjected to the force of the elastic device 2, the movable part 4 is closest to the first limiter 101. At this time, the spring bar 202 is in contact with the first electrode 501 to form an electrical circuit. The resistor 503 is used to prevent the first electrode 501 and the second electrode 502 from short-circuiting.

[0032] In one embodiment, a wiring port 504 and a cover plate 505 are provided on the outer surface of the protective shell 6. The wires of the wiring port 504 are electrically connected to the second electrode 502 and the spring bar 202 respectively; the cover plate 505 is hinged to the side of the protective shell 6; and a conduction button 103 is provided at the lower end of the wiring port 504.

[0033] In this embodiment, the wiring port 504 is used to connect an external explosive device and transmit an electrical signal to trigger the explosion of the explosive device; the cover 505 is used to protect the wiring port 504; when the wiring port 504 is connected to an external load, the conduction button 103 can be used to detect whether the circuit of the load is normal, that is, when the load circuit is normal, the conduction button 103 is turned on, and the conduction indicator light (not shown in the figure) arranged outside the protective shell 6 will light up green, otherwise the conduction indicator light will not light up.

[0034] In one embodiment, a first safety switch 701 and a second safety switch 702 are provided on the front end surface of the protective shell 6 , and the wires of the wiring port 504 are connected in series with the first safety switch 701 and the second safety switch 702 to achieve electrical connection.

[0035] In this embodiment, the first safety switch 701 corresponds to the release trigger mode, and the second safety switch 702 corresponds to the compression trigger mode. By adjusting the switches of the first safety switch 701 and the second safety switch 702 and using them together, the release trigger mode, the compression trigger mode, and the compression and release dual-purpose trigger mode can be realized, and the effects of different trigger modes required in different scenarios can be achieved.

[0036] In one embodiment, the front end surface of the protective shell 6 is provided with a fuse plug slot 703 and an insulating plug 704. The insulating plug 704 is configured as a "U"-shaped plug, with one end being longer than the other end.

[0037] In this embodiment, the fuse plug slot 703 is provided with two slots, the upper slot corresponds to the release trigger mode, and the lower slot corresponds to the compression trigger mode. When the long end of the insulating plug 704 is inserted into the upper slot, the release trigger mode is isolated, that is, the compression trigger mode is adopted; on the contrary, when the long end of the insulating plug 704 is inserted into the lower slot, the release trigger mode is adopted; when the insulating plug 704 is not inserted into the fuse plug slot 703, the compression and release dual-purpose trigger mode is adopted.

[0038] In one embodiment, the movable member 4 is provided with a second contact (not shown in the figure) near the end surface of the first electrode 501 , and the second contact is in non-permanent contact with the first electrode 501 .

[0039] In this embodiment, the second contact and the first contact are connected within the movable member 4. When the movable member 4 is subjected to an external force and is closest to the second stopper 102, the second contact contacts the first electrode 501, thereby electrically connecting the first electrode 501 to the wiring port 504 via the second contact, the movable member 4, the first contact, and the spring bar 202. When the movable member 4 is not subjected to an external force, the movable member 4 is closest to the first stopper 101. At this time, the spring bar 202 contacts the first electrode 501, and the first electrode 501 is electrically connected to the wiring port 504 via the spring bar 202. When the movable member 4 is subjected to an external force but is in a state intermediate between being closest to the first stopper 101 and being closest to the second stopper 102, the first electrode 501 is not electrically connected to the wiring port 504. An output indicator light (not shown) is provided on the outside of the protective housing 6. When the output indicator light is red, it indicates that the device is triggered, and when the output indicator light is off, it indicates that the device is not triggered.
