Position.Airfield runway, as the launching platform of various opportunities of combat, is the important leverage that battlefield control of the air is captured by Aviation Unit.So various countries
Anti- runway submunition all is being developed, interdiction capacity when realizing efficient strike to enemy's runway and be long, to contain that enemy is empty
Middle strength.
There is provided to the available trajectory environmental forces of fuse, seldom, and fuse is after anti-runway submunition is shed out in the air
Ensure security during usually duties processing, according to GJB373A《Fuze Safety Design criterion》Requirement, it is necessary to have twice only
Vertical insurance institution.When protecting environmental forces as one of fuse solution by the use of the overload produced during submunition parachute-opening, during due to parachute-opening
The overload values very little of generation, between 40g~80g, but duration of overload has 80ms, according to this feature, devises complications
Groove insurance institution.
The content of the invention
It is an object of the invention to provide a kind of Zigzag Devices that arming is overloaded suitable for parachute-opening.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of Zigzag Devices that arming is overloaded suitable for parachute-opening, including sleeve, steel ball, connecting rod, pedestal are with being used to
Property cylinder；Otch is set the outer wall of the sleeve one end in a ring, and vertical its is axially arranged with banking pin on inwall, the ring of the sleeve
Shape cut ends are inserted in the die cavity of pedestal；The inertia cylinder is in inverted T shaped shape, and the side wall of its upper shell is provided with relative S
Shape groove and steel-ball groove；Annular incision end of the upper shell through sleeve of the inertia cylinder is stretched into sleeve, and the banking pin of sleeve is set
In S-shaped groove, steel ball sets in steel-ball groove and carried out by sleeve lining spacing；Described connecting rod one end is passed through successively straight up
The dividing plate in base cavity and the catch being located on dividing plate are worn, and is threaded io in the groove that inertia cylinder bottom is provided with,
Rear marshall springs is arranged with connecting rod.
Annular incision end external diameter of the sleeve and the die cavity internal diameter of pedestal are adapted；Axle of the S-shaped groove along upper shell
Line direction is set, and the oblique top of steel-ball groove is set and with the axis of upper shell in 45 degree of angles；The base diameter of the inertia cylinder
It is adapted with the die cavity internal diameter of pedestal；The rear marshall springs is located between the groove of catch and inertia cylinder.
Beneficial effects of the present invention：1) there is tortuous groove on the mechanism inertia cylinder, inertia cylinder overcomes bullet under overload power effect
Spring drag, can only be moved along banking pin by serpentine, delay mechanism kinematic arrival time, with sentencing to duration of overload
Other ability；Recognizable overload environment, is to fall overload, or the overload produced during parachute-opening；Fall overload, duration in this way
Short, mechanism will not be moved in place, it is ensured that security when usually duties are handled；
2) mechanism has self-lock ability, and after inertia cylinder motion in place, steel ball comes off, and blocks inertia cylinder, is disappeared in overload
Afterwards, it is caused to return to rigging position.

Embodiment
A kind of Zigzag Devices that arming is overloaded suitable for parachute-opening, as Figure 1-4, including sleeve 1, steel ball 2, company
Extension bar 5, pedestal 7 and inertia cylinder 8；Wherein, otch is set the outer wall of the one end of sleeve 1 in a ring, and its vertical axial direction is set on inwall
There is banking pin 3, annular incision end of the sleeve 1 is inserted in the die cavity of pedestal 7, annular incision end external diameter and the pedestal 7 of sleeve 1
Die cavity internal diameter be adapted；
Above-mentioned inertia cylinder 8 is in inverted T shaped shape, and the side wall of its upper shell is provided with relative S-shaped groove 10 and steel-ball groove 9, S-shaped
Axis direction of the groove 10 along upper shell is set, and the oblique top of steel-ball groove 9 is set and with the axis of upper shell in 45 degree of angles；Inertia
The base diameter of cylinder 8 is adapted with the die cavity internal diameter of pedestal 7；
Annular incision end of the upper shell through sleeve 1 of inertia cylinder 8 is stretched into sleeve, and the banking pin 3 of sleeve 1 is arranged on S-shaped
In groove 10, steel ball 2 sets in steel-ball groove 9 and carried out by the inwall of sleeve 1 spacing；
Above-mentioned one end of connecting rod 5 sequentially passes through the dividing plate in the die cavity of pedestal 7 and the catch being located on dividing plate straight up
6, and be threaded io in the groove that 8 bottoms of inertia cylinder are provided with, rear marshall springs 4 is arranged with connecting rod 5, rear marshall springs 4 is located at gear
Between the groove of piece 6 and inertia cylinder 8；
Working method of the present invention：Referring to Fig. 2, the mechanism inertia cylinder inertia cylinder overcomes spring resistance under overload power effect,
It can only be moved along banking pin by serpentine, delay mechanism kinematic arrival time, with to duration of overload discriminating power；
Recognizable overload environment, is to fall overload, or the overload produced during parachute-opening；Fall overload in this way, the duration is short, mechanism is not
It can move in place, it is ensured that security when usually duties are handled；After inertia cylinder motion in place, steel ball comes off, and inertia cylinder is blocked, in mistake
Carry after disappearing, cause it to return to rigging position.
There is fuse to postpone arming effect for the mechanism, in fuse usually duties processing assembling, transportation, even if
Fuse is fallen, although its overload values is more than 80g, falls duration of overload and there was only Millisecond, under overloading herein, the machine
Structure will not be moved in place, and steel ball will not fall off, and after overload disappearance under spring resistance effect, mechanism returns to original dress again
With position, still in safety position, it is ensured that security when usually duties are handled.But when the overload produced during submunition parachute-opening continues
Between it is long, can allow inertia cylinder overcome spring resistance, along tortuous groove decline in place, discharge steel ball, arming.
Above content is only to structure example of the present invention and explanation, affiliated those skilled in the art couple
Described specific embodiment is made various modifications or supplement or substituted using similar mode, without departing from invention
Structure surmounts scope defined in the claims, all should belong to protection scope of the present invention.
