Abstract

The utility model discloses a pick-proof safe box which comprises a box body and a box door. The periphery of the box door is of a sawtooth-shaped or arc-shaped structure; and a sawtooth-shaped or arc-shaped structure matched with the box door is arranged on the box body. The pick-proof safe box has the beneficial effect that a sawtooth-shaped or arc-shaped structure is adopted at a door crack where the box door is matched with the box body, so that a burglar can be effectively prevented from picking the safe box for stealing by using a flat shovel, a screwdriver or other tools, and the safety of valuables inside the safe box is protected. The pick-proof safe box has the advantages of simple structure and low manufacturing cost.

Description

A kind of anti-prying case

Technical field

The utility model relates to the anti-thefting facility technical field, especially relates to a kind of anti-prying case.

Background technology

Present existing strongbox; Except the fastness of enforced safe; The pick-proof technology mainly concentrates on the function of lock, for example increases the complexity of lock & key structure, adopts electronic password lock, fingerprint recognition lock to wait to reach and prevent that other people from opening the purpose of strongbox.Though but these strongboxs have increased the difficulty that other people unpack, steal the person for carrying out the destructiveness sled, still have an opportunity to take advantage of.

Chinese patent document (the day for announcing: June 21 nineteen ninety-five; Notification number: CN2201471Y) disclose the safe that a kind of anti-destructive is stolen; Comprise casing with the chamber door of the equipped mutually door lock assembly that lock core and combination disk are arranged of casing; The fitting face of chamber door and casing all becomes the α angle lapping oblique with the chamber door face, and 0 ° < < 90 °, the gap between the fitting face is less than 0.02 millimeter for α.The lock core front end has protective jacket and anti-protection pad, and the password card flushes with chamber door, and keyhole is arranged on the card.Though technique scheme also can solve the effect of safe pick-proof, this complex structure, cost of manufacture is high.

The utility model content

The purpose of the utility model is to provide a kind of simple in structure, the anti-prying case that cost is low for the problem that solves the strongbox pick-proof.

The utility model realizes that the technical scheme that its technical purpose adopted is: a kind of anti-prying case; Comprise casing and chamber door; The periphery of described chamber door is zigzag or arc structure, and described casing is provided with zigzag or the arc structure adaptive with chamber door.Chamber door cooperates the crack between a door and its frame place to adopt zigzag or arc structure with casing; Like this when the thief uses means of destruction to destroy; Even if using instrument safebreakers such as flat chisel or screwdriver steals; Because periphery adopts zigzag or arc structure fully; It is very difficult thing that stealing tool such as flat chisel or screwdriver inserts inside through sawtooth cooperation place or arc structure cooperation place, has so just prevented that strongbox from suffering destructive theft, protected the safety of inner valuables effectively.

As preferably, it is bar linkage structure that described casing and chamber door are opened parts.Adopt connecting rod to open parts, can guarantee like this that chamber door is parallel to open, and do not receive the restriction of zigzag or arc structure, the user opens conveniently.

As preferably, the zigzag on the chamber door periphery or the tooth depth of arc structure be 5.6 to 6.4 millimeters or arc radius protruding be 1.6 to 2 millimeters, sunk be 4 to 4.4 millimeters.Adopt the sawtooth or the arc structure of this structure, promptly satisfied the structural requirement of pick-proof, make easy to make again.

As preferably, the zigzag on the casing or the tooth depth of arc structure are that 5.6 to 6.4 millimeters or arc radius are 2.8 to 3.2 millimeters.Said structure can cooperate with chamber door well, and can guarantee the pick-proof effect.

As preferably, zigzag on zigzag on the chamber door periphery or arc structure and the casing or the fit clearance between the arc structure are 1.0 to 1.4 millimeters.The excessive purpose that does not have pick-proof of fit clearance, the too small making of fit clearance is complicated, and user's use meeting appearance unlatching friction, brings inconvenience to the user.

The utility model beneficial effect is: chamber door cooperates the crack between a door and its frame place to adopt zigzag or arc structure with casing, the person that can not avoid theft effectively uses instrument safebreakers such as flat chisel or screwdriver to steal, and has protected the safety of inner valuables.This scenario-frame is simple, and cost of manufacture is low.

The specific embodiment

Below through specific embodiment and combine accompanying drawing that the technical scheme of the utility model is further specified.

Embodiment 1:

In the embodiment shown in fig. 1; A kind of anti-prying case comprises casing 1 and a rectangular chamber door 2, certainly; Chamber door 2 also can be circular or other shapes; Around the described chamber door 2 is arc structure 3, and the arc radius of arc structure 3 bossings is 1.8 millimeters, and the arc radius of dented part is 4.2 millimeters.

In the position that chamber door 2 is set, be provided with the arc structure 4 adaptive with chamber door 2 on the described casing 1, the two-part arc radius up and down of arc structure 4 is 3.0 millimeters.

Arc structure 3 and the fit clearance between the arc structure 4 on the casing 1 on chamber door 2 peripheries are 1.2 millimeters (see figure 2)s.

It is bar linkage structure that described casing 1 is opened parts with chamber door 2, and like this when opening chamber door 2, chamber door 2 can along continuous straight runs is parallel be opened, and can not receive the restriction of arc structure.

Embodiment 2:

In the embodiment shown in fig. 3, a kind of anti-prying case comprises the chamber door 2 of a casing 1 and a circle, and certainly, chamber door 2 also can be square or other shapes, and the circumference of described chamber door 2 is a laciniation 3, and the tooth depth of laciniation 3 is 4.8 millimeters.

In the position that chamber door 2 is set, be provided with the laciniation 4 adaptive with chamber door 2 on the described casing 1, the tooth depth of laciniation 4 is 4.8 millimeters.

Laciniation 3 and the fit clearance between the laciniation 4 on the casing 1 on chamber door 2 circumferential edge are 1.2 millimeters (see figure 4)s.
