The invention relates to a lock core for preventing the lock from being prized by strong collision using anticollision key, belonging to the field of locks, which comprises an inner core of the lock core, a lock core body, a plurality of pin holes arranged in row on the inner core of the lock core and the lock core body and communicated with the each other, a lower pin in the pin hole of the inner core of the lock core, an enclosed pin arranged in the top part of the pin hole of the lock core, a spring, an upper pin, and a key hole. The lock core is characterized in that: at least one column of each row of the pin holes of the inner core of the lock core with an anticollision key pin which is suspended in the pin hole of the inner core of the lock core, the upper edge of the anticollision key pin is lower than the surface of the inner core of the lock core, while the lower edge is higher than the bottom of the pin hole of the inner core of the lock core; a cylindrical thin form pin is arranged under the spring. When the collision key is under strong collision, the teeth of the collision key can only collide the common lower pin without colliding the pin of the anticollision key; under the action of the cylindrical thin form pin, the upper pin corresponded with the pin of the anticollision key can not be ejected from the pin hole of the inner core of the lock core and be blocked between the upper pin hole and the lower pin hole in the collision process of the collision key, thus the lock core for preventing the lock from being prized by strong collision using anticollision key has the advantages of ensuring safety by enabling the lock core to be unlocked.

A short-process preparation method of TA5 titanium alloy medium-thick plate for ships, which adopts the whole-process process design concept, and comprehensively controls the edge of TA5 medium-thick plate from the aspects of slab selection, widening and reversing rolling, heat treatment process design, etc. Cracks, plate shape, structure and performance, the slab used in the production of medium and thick plates by this method is small, the production is convenient and flexible, and the requirements for equipment capacity are low.

The invention discloses a safety cabinet which cannot be carried away or prized up but can send an alarm. The safety cabinet consists of a cabinet body (1) and a cabinet door (2), wherein the cabinet door (2) is provided with a latch structure for realizing opening and closing with the cabinet body (1) and a coded lock for controlling opening of the latch; a bottom plate (9) of the cabinet body (1) is provided with a ground screw hole (10); a rear box plate (7) of the cabinet body (1) is provided with a wall screw hole (8); and the cabinet body (1) is fixed with the ground and the wall through the ground screw hole (10) and the wall screw hole (8) by using a ground screw (11) and a wall screw (12). The safety cabinet is a real safety cabinet which cannot be carried away, prized up or opened without password.
