Description

Safety box for examination paper

The utility model belongs to daily necessities stationery class.

Examination over the years relates in particular to large-scale examination, as national unified exam etc., because paper is finalized a text, printing sets the exam to the examination hall, is arranged, though take multiple secrecy provision a time interval, also idol has the examination question leakage of a state or party secret or malpractices thing to take place, and causes inequality to strive unexpectedly with incident and takes place.

The purpose of this utility model is to provide a kind of being difficult for to divulge a secret, the examination paper secrecy box of time opening.

A kind of examination paper secrecy box of forming by casing ［ 4 ］, case lid ［ 5 ］, it is characterized in that lockhole ［ 3 ］ is arranged at casing antetheca top, indicator lamp hole ［ 6 ］ is arranged above the case lid, the cover wall interlayer keeps timing mechanism ［ 2 ］, front end is the interior dead bolt ［ 1 ］ of stretched in lockhole of this mechanism controls, this timing mechanism is one to connect the closed-loop path of timer ［ 13 ］ and electromagnetic coil ［ 10 ］ and indicator lamp ［ 11 ］ by power supply ［ 12 ］, the electromagnetic coil top have relatively spring ［ 7 ］ around the front end that is fixed in location-plate ［ 8 ］ hole be iron bar ［ 9 ］ formation of dead bolt.

During use, after jewelry, bond, the money that maybe need maintain secrecy paper places inside to reserve the time, behind the case lid that closes, dead bolt is under the effect of spring, automatically case lid is locked, under the situation of non-outside destroy, case lid is difficult for opening, arrive fixed moment, timer is connected circuit, produces magnetic field in the electromagnetic coil dead bolt and iron bar are held, and dead bolt leaves lockhole, indicator lamp is also bright, informs and can take out the inner thing of hiding.

The advantage of this utility model is simple in structure, but preservation needs property, paper secret in the certain hour, gives away secrets or has things stolen in the in transit unlikely or interim storage life.

Accompanying drawing 1 is the examination paper secrecy box structural representation, and Fig. 2 is the timing architecture schematic diagram, wherein the 1--dead bolt; The 2--timing mechanism; The 3--lockhole; The 4--casing; The 5--case lid; The 6--indicator lamp hole; The 7--spring; The 8--location-plate; The 9--iron bar; The 10--electromagnetic coil; The 11--indicator lamp; The 12--power supply; The 13--timer.

Can on the correspondence position of the casing front end dead bolt of required size, hold lockhole successfully during enforcement, install the closed-loop path that timer, power supply, indicator lamp, electromagnetic coil as the binding of figure circuit constitute in case lid inside, and get final product at electromagnetic coil fore device location-plate and the spring that is with iron bar.
