Like a patent No. is the Chinese utility model patent " inverted hook type pick-proof bolt apparatus " of ZL96229428.4 (notification number is CN2269454Y); Application number is the Chinese invention patent " being used for the door bolt mechanism on the strongbox " of ZL200510060496.2 (publication number is CN1730886Y); Like a patent No. is the Chinese utility model patent " a kind of pick-proof latch locking structure " of ZL200920118215.8 (notification number is CN201391123Y), and they all disclose the similar pick-proof latch locking structure of pick-proof principle.
Yet aforementioned bolt structure more complicated, and the bolt Drive Structure that needs otherwise designed to make new advances.
Summary of the invention
The utility model technical problem to be solved is the pick-proof mechanism that a kind of simple and reasonable, safety good, cost is low safety cabinet is provided to above-mentioned prior art present situation, and this mechanism can prevent effectively that the door-plate of fastening a lock part with a bolt or latch from being moved and prizing flange by sled.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of pick-proof mechanism of safety cabinet; The interior straight doorframe that comprises a side in the opening that is fixed on cabinet; And the cabinet door that matches with the opening profile of cabinet, the back side of cabinet door have can slippage the door bolt head, have a door bolt hole that supplies said door bolt head to insert on the inner face of interior straight doorframe; It is characterized in that: a corresponding door bolt position, the back side of said cabinet door is provided with the anti-skid plate that extends internally; Have the pick-proof hole that supplies said door bolt head to pass on the anti-skid plate, have the jack that supplies anti-skid plate to insert on the said interior straight doorframe front end face, under the fixed state of cabinet door lock; Said anti-skid plate inserts said jack and gets into interior straight doorframe, and said door bolt head inserts in the said pick-proof hole after then passing the door bolt hole.
Straight doorframe is the substrate that cross section is the U type basically in above-mentioned, and the inner face of the front end face of interior straight doorframe and the opening of cabinet is fixed together.Be somebody's turn to do interior straight doorframe in guaranteed strength, simple in structure, convenient processing and installation.
Be welded with the gripper shoe that two intervals are provided with in above-mentioned in the U type groove of straight doorframe.Support through gripper shoe can strengthen interior straight doorframe intensity.
Compared with prior art, the advantage of the utility model is: a corresponding door bolt position, the back side of cabinet door is provided with the anti-skid plate that extends internally, under the fixed state of cabinet door lock; Anti-skid plate on the cabinet door inserts jack and straight doorframe and straight doorframe in fastening in getting into, qualification effect about jack has anti-skid plate, and cabinet door and interior straight doorframe position are defined in planar range; The door bolt head also can insert in the pick-proof hole of anti-skid plate simultaneously; Can the cabinet door be limited in vertical direction again, make cabinet door and cabinet combine together, lawless person's cabinet door when prizing the cabinet door can not move in planar range yet; And, strengthen the pick-proof performance of cabinet door level and fore-and-aft direction with cabinet door sled flange.
