Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0016] The novel strong locking and weak unlocking mechanism of the present invention is composed of actuator 5, connector 2, upper airfoil 1, lower airfoil 3 and fixing pin 4; upper airfoil 1 and lower airfoil 3 are provided with lock Slots, in the initial working state, the two lock slots are aligned; the connector 2 is slidably set in the lock slot; the pin hole on the upper airfoil corresponds to the position on the connector; the fixing pin passes through the pin of the connector and the upper airfoil The holes are used to lock the positions of the upper airfoil, the lower airfoil and the connectors.

[0017] The length of the connector located in the upper and lower wing lock grooves is 5mm, which can ensure the strength of locking and the shearing force when unlocking.

[0018] The locking force on the airfoil mainly depends on the stru...

Abstract

The invention provides a novel strong locking and weak unlocking mechanism. The mechanism is composed of an actuator, connecting pieces, an upper wing surface, a lower wing surface and fixing pins. Locking grooves are formed in the upper wing surface and the lower wing surface, and the two locking grooves are aligned in an initial working state. The connecting pieces are slidably arranged in the locking grooves. Pin holes with corresponding positions are formed in the upper wing surface and the connecting pieces. The fixing pins penetrate through the pin holes of the connecting pieces and the upper wing surface to lock the positions of the upper wing surface, the lower wing surface and the connecting pieces. The novel strong locking and weak unlocking mechanism has the advantages that the locking force is large, and reliable locking of a missile airfoil folding and unfolding mechanism under the condition of large external load in the initial state is guaranteed; and when the mechanism moves, the mechanism can be reliably unlocked only by a very small unlocking force.

Description

technical field [0001] The invention belongs to the field of weapons and equipment, and is a locking mechanism of a missile wingspan mechanism, in particular to a novel strong locking and weak unlocking mechanism. Background technique [0002] According to the more and more stringent use requirements of current missiles, under heavy load conditions, before the missile wing folding and unfolding mechanism is deployed, it must be reliably locked and kept in a folded state. After the actuator works, the mechanism must be reliably unlocked, so that the mechanism Expand into place. [0003] According to the survey, the locking mechanism of the missile wingspan mechanism commonly used at home and abroad at present all adopts the shear pin method, relying on the shear strength of the shear pin material itself, the initial locking force required for the folding and unfolding mechanism is calculated, Then process it into a cylindrical shear pin, install it in the pin hole, and keep ...
