Shield locking mechanism

The invention relates to a shield locking mechanism, and belongs to the technical field of weapon fire control systems. According to the locking mechanism for the gunner sighting telescope shield, locking of the gunner sighting telescope shield is achieved through transverse movement of a locking sliding block and longitudinal movement of a locking support. Meanwhile, due to the fact that a locking clamping hand makes contact with a locking stop lever through a plane, the locking force is increased through a locking elastic piece on the plane, and therefore protection on the gunner sighting telescope shield can be enhanced. On one hand, the locking mechanism can protect the gunner sighting telescope shield against damage in the running state of an armored vehicle, and no interference is caused to work of the armored vehicle; and on the other hand, when the armored vehicle does not work, the locking mechanism is unlocked, and gunner sighting telescope shield can protect an upper telescope body of the gunner si
