Abstract
The invention provides a centrifugal safety mechanism of a fire extinguishing bomb fuze. The centrifugal safety mechanism comprises a ladder groove, a centrifugal pin, a slide block, a spring, a spring base and a double-wing shrapnel, wherein the centrifugal pin is fixedly connected with the slide block; the double-wing shrapnel is fixed on the slide block; the spring is mounted between the slide block and the spring base; one end of the spring is abutted against the slide block and the other end of the spring is abutted against the spring base; and the double-wing shrapnel, the centrifugal pin, the slide block, the spring and the spring base are located in a fuze safety mechanism chamber formed in a fire extinguishing bomb. With the implementation of the technical scheme disclosed by the invention, the fire extinguishing bomb fuze arming can not occur before emission and also fuze arming can be achieved reliably after the emission. The mechanism disclosed by the invention is simple and novel in design, reasonable, safe and reliable; and the safety and reliability of the fire extinguishing bomb fuze are effectively achieved.
Description
Technical field
The invention belongs to the fire extinguisher bomb technical field, particularly a kind of centrifugal insurance institution of fire extinguisher bomb fuse is applicable to mortar fire extinguisher bomb fuse, howitzer fire extinguisher bomb fuse and relevant fire extinguisher bomb fuse product pickaback.
Background technology
The fire extinguisher bomb fuse plays a part to ignite fire extinguisher bomb as an important component part of fire extinguisher bomb system.Centrifugal insurance institution plays important safety effect as an important component part of fire extinguisher bomb fuze system.Centrifugal insurance institution is the firing device that prevents the fire extinguisher bomb fuse, in duties are handled or the effect that in emission process, meets accident, the mechanism of energy arming under predetermined condition.Therefore, the effect of centrifugal insurance institution in the fire extinguisher bomb fuse is that the firing device that guarantees the fire extinguisher bomb fuse is in safety position, the emission back trajectory certain a bit on, by safety position to the arm-to-arm transition and finally enter arm-to-arm, i.e. arming.So how to make the fire extinguisher bomb fuse before emission, not remove insurance, again can be after emission arming reliably, be the reliable difficult problem of fire extinguisher bomb fuze safety.If fire extinguisher bomb fuse energy safety, reliable arming, fire extinguisher bomb fuse ability will have breakthrough change.
Summary of the invention
The object of the invention has provided a kind of centrifugal insurance institution of fire extinguisher bomb fuse, solves the reliable difficult problem of fire extinguisher bomb fuze safety.Change the insurance institution of fire extinguisher bomb fuse into have the dipteron shell fragment centrifugal lock insurance institution, significantly improved safe, the reliable ability of fire extinguisher bomb fuse.
The technical scheme that adopts is:
A kind of centrifugal insurance institution of fire extinguisher bomb fuse comprises step trough, centrifugal lock, slide block, spring, spring pedestal and dipteron shell fragment.Centrifugal lock is fixedlyed connected with slide block, and the dipteron shell fragment is fixed on the slide block, and spring is installed in the middle of slide block and the spring pedestal.
Spring one end is replaced on slide block, and its other end is replaced on spring pedestal.It is indoor that dipteron shell fragment, centrifugal lock, slide block, spring and spring pedestal are positioned at the fuze safety mechanism offered of fire extinguishing spring.
Fire extinguisher bomb is by mortar or howitzer when emission pickaback, firing pin moment is born very big recoil, centrifugal lock blocks the firing pin slide block, stop firing pin to move backward, rotating speed maximum when fire extinguisher bomb arrives gun muzzle, centrifugal lock breaks away from pivot (firing pin axis), spring compression, the dipteron shell fragment flicks by step trough and blocks behind the dipteron shell fragment top landing step trough, and fire extinguisher bomb reduces insurance at the flight course medium speed can not got involved again.Fire extinguishing is bound to the scene of a fire, and fire extinguisher bomb is ignited by the fire extinguisher bomb fuse.
Fire extinguisher bomb is by mortar or howitzer when emission pickaback, firing pin moment is born very big recoil, centrifugal lock blocks firing pin, stop firing pin to move backward, rotating speed maximum when fire extinguisher bomb arrives gun muzzle, centrifugal lock breaks away from pivot, spring compression, the dipteron shell fragment flicks by step trough and blocks behind the dipteron shell fragment top landing step trough, and fire extinguisher bomb reduces insurance at the flight course medium speed can not got involved again.Fire extinguishing is bound to the scene of a fire, and fire extinguisher bomb is ignited by the fire extinguisher bomb fuse.
Advantage and effect: by the enforcement of technical solution of the present invention, the fire extinguisher bomb fuse can not removed insurance before emission, again can arming reliably after emission.Mechanism design of the present invention is simple novel, reasonable, safe and reliable, efficiently solves the reliable difficult problem of fire extinguisher bomb fuze safety.

Fig. 1 is structural representation of the present invention.
Fig. 2 is the present invention and firing pin connection diagram.
The specific embodiment
A kind of centrifugal insurance institution of fire extinguisher bomb fuse comprises step trough 2, centrifugal lock 1, slide block 3, spring 4, spring pedestal 5 and dipteron shell fragment 8.Centrifugal lock 1 is fixedlyed connected with slide block 3, and dipteron shell fragment 8 is fixed on the slide block 3, and spring 4 is installed in the middle of slide block 3 and the spring pedestal 5.
Spring 4 one ends are replaced on slide block 3, and its other end is replaced on spring pedestal 5.Dipteron shell fragment 8, centrifugal lock 1, slide block 3, spring 4 and spring pedestal 5 are positioned at the fuze safety mechanism chamber 9 that fire extinguisher bomb is offered.
Fire extinguisher bomb is by mortar or howitzer when emission pickaback, 7 moments of firing pin are born very big recoil, centrifugal lock 1 blocks firing pin slide block 6, stop firing pin 7 to move backward, rotating speed maximum when fire extinguisher bomb arrives gun muzzle, centrifugal lock 1 breaks away from pivot (firing pin 7 axis), and spring 4 compresses, dipteron shell fragment 8 flicks by step trough and blocks behind the dipteron shell fragment 8 top landing step troughs, and fire extinguisher bomb reduces insurance at the flight course medium speed can not got involved again.Fire extinguishing is bound to the scene of a fire, and fire extinguisher bomb is ignited by the fire extinguisher bomb fuse.
