As an embodiment of the present invention, the following is described in detail:

1. structural composition

Integral composition

The three-purpose landmine fuze mainly comprises a shell 1, a pressing rod 31, a pressing rod spring 314, a firing pin 33, a firing pin spring 35, a loosening plate 32, a safety clamp 24, a loosening plate control pin 23, a pressing rod control pin 22, a safety pin 21, a tripping wire, a binding rope, a detonation circuit (a pressing switch, a switch seat, a battery box, a safety indicator lamp) and the like, as shown in fig. 1 and 2.

(II) component Structure

1. Shell 1

The shell 1 is used for accommodating and fixing other parts. The casing 1 has 5 holes for mounting the hair loosening plate control pin 23, the hair pressing lever control pin 22, the safety pin 21, the binding rope, and the like, respectively.

2. Firing pin 33

The striker 33 is a metal rod with uneven thickness. In the safety state, the firing pin 33 is restricted from being fired by the firing rod 31 and the release plate 32. After the fuze is triggered, the firing pin 33 ejects and impacts the pressing switch to switch on the electric detonating circuit under the action of the extension force of the spring.

3. Hair pressing bar 31

The hair pressing bar 31 is provided with a special-shaped hole. The size of the narrow hole 313 is larger than the thin portion 333 of the firing pin 33 and smaller than the thick portion of the firing pin 33. The wide hole 312 is larger in size than the thick portion of the striker pin 33. The detail 333 of the firing pin 33 is controlled by the narrow hole of the firing rod 31 to be unfired when the fuze is in the safe and fight state; when the pressure rod 31 is subjected to pressure drop, the wide hole is aligned with the firing pin rod, the firing pin 33 is out of control, and the firing pin spring 35 ejects under the action of stretching force. The second pressing rod control hole 311 is also arranged on the pressing rod 31, and is used for enabling the pressing rod control pin 22 to simultaneously pass through the shell 1 and the first pressing rod control hole 141 on the pressing rod 31 when the pressing rod control hole is set into a pulling or loosening mode, so that the firing pin 33 can smoothly pass through the wide hole 312 without being limited by the narrow hole 313 when the fuze is released by pulling force or pressure on the loosening plate 32 against the wide hole 312 of the positive pressing rod 31.

4. Rod spring 314

The hold down spring 314 is mounted between the hold down bar 31 and the annular support table 14. When the fuze is in a combat state, the tension of the plunger spring 314 prevents the plunger from descending, and the thin portion 333 of the striker 33 is caught in the narrow hole 313 of the firing rod 31, thus preventing firing. When the pressure applied to the presser bar 31 overcomes the tensile force of the presser bar spring 314, the presser bar descends, and the striker 33 engages the wide hole 312 of the presser bar 31.

5. Firing pin spring 35

In the combat state, the firing pin spring 35 is in a compressed state, and once the fuze is triggered to lose restriction of the firing pin 33, the firing pin 33 is ejected to strike the pressing switch to switch on the electric detonating circuit under the action of the extension force of the firing pin spring 35.

6. Hair loosening plate 32

The release plate 32 is an L-shaped metal sheet, and is controlled by a release plate safety pin to not turn over in a safety state, so that the tail of the firing pin is controlled to prevent the firing pin 33 from firing.

7. Detonating circuit

The detonating circuit consists of a push switch, a switch seat, a battery box, a safety indicator lamp and the like. The circuit diagram is shown in fig. 6. The safety indicator lamp is connected with the electric detonator in parallel. The indicator light has the function of lighting up the circuit once the circuit is connected accidentally, and prompting that the electric detonator cannot be connected any more. The push switch is struck by the firing pin 33 to switch on the line, causing the electric detonator to explode.

8. Safety clip 24

The safety clip 24 is a metal clip. The safety device is installed between the annular supporting table 14 and the hair pressing bar 31 in a safety state, and the hair pressing bar 31 is supported so as not to descend even if being pressed. It needs to be pumped out when setting.

9. Hair loosening plate control pin 23

The trigger pin 23 is inserted into the trigger hole of the casing 1 in the safety state to restrict the trigger 32 from being turned over, thereby blocking the firing pin 33. Setting in the hair pressing mode requires pulling it off and removing the hair-loosening plate 32; when the hair loosening mode is set, firstly, a weight is placed on the hair loosening plate 32 to press the hair loosening plate 32, and then the hair loosening plate control pin 23 is pulled out; when the trigger is set in the pulling mode, the trigger wire is connected with the trigger plate control pin 23, the trigger wire is pulled by pulling force to pull the trigger wire out of the trigger plate control hole, the trigger plate 32 is turned over under the extending force of the trigger spring 35, and the trigger pin 33 is out of control.

10. Hair pressing lever control pin 22

The hold down lever control pin 22 is only used when Cheng Lafa and the release mode are set. The pressing rod 31 is pressed down to align the pressing rod 31 with the pressing rod control hole in the case 1, the pressing rod control pin 22 is inserted, the pressing rod 31 is restricted, and the thick portion of the striker 33 is aligned with the wide hole 312 of the pressing rod 31.

11. Safety pin 21

The function of the safety pin 21 is to ensure the safety of the operator during the lightning stroke, and to be pulled out in the final link of the lightning stroke. Regardless of whether the setting is in the squeeze, pull or loose mode, the striker 33 may accidentally fire during the setting without being perceived by the operator. Accidental firing of the firing pin 33 will push against the safety pin 21 and not be able to strike the push switch and the circuit will not be closed. Although the operator cannot see the inside, the operator can feel a significant resistance when pulling out the safety pin 21, and cannot pull out it.

2. Principle of ignition

Safety state (one)

In the safety state, the loosening plate 32 is controlled by the loosening plate control pin 23 and cannot be turned over, the firing pin 33 is clamped by the loosening plate 32 and cannot be fired, and the fuse is in the safety state. The firing bar 31 is also controlled by the safety clip 24 and cannot descend, the thin part 333 of the firing pin 33 is blocked by the clamping groove 334 of the firing bar 31 and cannot fire, and the fuse is also in a safe state. The safety pin 21 is inserted into the safety pin hole, and can block the striker 33 from striking the push switch even if it is accidentally fired. The electric detonating circuit is in a broken state in the safety state, and the electric detonator and the fuze are connected in the safety state. If the circuit is accidentally turned on in the carrying process, the safety indicator lamp can be lightened, and the electric detonator cannot be accessed when the prompting circuit is turned on.

(II) combat State

The trip wire is connected with the trigger plate control pin 23, the safety pin 21 is pulled out, and the fuze enters a fight state. At this time, the striker 33 is against the thick portion of the positive pressure-transmitting lever 31, but is not fired due to the control of the release plate 32. When the trip wire is pulled out by more than 2kg of tension, the trigger releasing plate 32 is out of control, the trip wire is turned over under the action of the extension force of the firing pin spring 35, and the firing pin 33 is out of control.

3. Set to a hair loosening mode

When the hair loosening mode is set, the safety clip 24 is removed, the hair pressing rod 31 is pushed to the bottom, the hair pressing rod 31 is aligned with the hair pressing rod control hole in the shell 1, and the hair pressing rod control pin 22 is inserted. At this time, the striker 33 is against the thick portion of the positive pressure-transmitting lever 31, but is not fired due to the control of the release plate 32. Pressing a weight for camouflage against the hair loosening plate 32 presses the hair loosening plate 32, pulling out the hair loosening plate control pin 23, pulling out the safety pin 21, and putting the fuze into a combat state. When the weight is taken off by an enemy, the trigger plate 32 loses control of the weight, turns over under the tensile force of the firing pin spring 35, and the firing pin 33 loses control of firing.
