Abstract

The utility model relates to a prying-proof safe. The utility model is characterized in that the inner part of the door body of a safe door is provided with an installing bottom board on which driving gears and four movable racks engaged with the gears are arranged, wherein, each rack is respectively and fixedly connected with movable bolts arranged around the door body through connecting rods to positively and reversely rotate the gears, the multi-direction bolts can be driven to do synchronous telescoping motion through the racks and the connecting rods so that a locking and an unlocking actions are accomplished, and in addition, the prying-proof safe can also be provided with a bolt sloping structure, and the periphery of the grooving disk of a puzzle lock is sheathed with a protective shell. The utility model has the advantages of reasonable structure, high manufacturing and installing precision, convenient operation and good prying-proof performance, and the bolt can be deeply inserted in the inner side wall of a door frame.

Description

The anti-prying cabinet

The utility model relates to a kind of burglary insurance apparatus, particularly a kind of improved anti-prying cabinet.

Existing safety cabinet, the formations such as runners that mainly comprise cabinet, cabinet door, band steamboat, wherein the safe door of the main parts of safety cabinet generally is single bolt (simple gate door bolt) anti-theft device (but the anti-device of stealing of the warning of also being furnished with private code that has) that is made of digital cipher lock and common commercially available cylinder lock combination, above-mentioned safety cabinet is preventing that the thief is with master key unblank aspect the pilferage comparatively effectively (password security device that has is also very effective at last aspect anti-the unblanking), regrettably its pick-proof poor performance.In order to improve the safety of safe door, what have is installing the synchronous multidirectional keeper that the employing lever actuated also is installed that loose-leaf bearing pin one side (being hingen one side) adds dark bolt, has in the cabinet door, but still there are more following defectives in above-mentioned safety cabinet, causes the pick-proof performance still not ideal enough:

1, adopts dark bolt, weld extremely on the door limit because of dark bolt is normally fixing during fabrication, make dark bolt length can not do long enough, can't insert in the inside wall of cabinet doorframe more deeply at closing time, if do dark bolt longer, then can be against on the doorframe at closing time, thereby adopt dark bolt, the pick-proof performance of frame door is not ideal enough.

2, adopt the synchronous multidirectional keeper of lever actuated, also be restricted (keeper and keyhole eye must big slits wide cooperate favourable the shutting of) because of reasons in structure own makes the actuating precision, cause the pick-proof effect to be under some influence.

3, the slotted panel of the inner superimposed installation of coded lock is because of unprotect cap device; when the accent sign indicating number knob (axle) that exposes and face are prized by the thief (accent sign indicating number knob＜axle that notes expose〉and face is very easy fallen) by sled; often cause slotted panel to drop one after another or be scattered; make coded lock lose function of use; at this moment the thief need only use the unlocked by universal key cylinder lock, can open safe door.

The purpose of this utility model provides a kind of improved safety cabinet with splendid pick-proof performance, make it to have simple in structure, installation accuracy height, the firm advantage of safety.

The utility model mainly is to adopt multidirectional technical schemes that tie the anti-body device of forcing open the door of lock of gear drive to realize more: it comprises cabinet, formations such as cabinet door and runners, wherein be fitted with (machinery) digital cipher lock and cylinder lock on safety cabinet every body, (peripheral direction difference) is provided with movable keeper on the door body, it is characterized in that being provided with a base plate in door body inside, on this base plate, be equipped with driven wheel and with four movable tooth bars of gears engaged, wherein every toothed rack is fixedly connected with the movable keeper that is contained in around the body respectively by connecting rod again, the rotating transmitting gear, can do the synchronization telescope motion by the keeper of tooth bar and connecting rod driving peripheral direction, lock and unlocking action to finish.

Below in conjunction with accompanying drawing embodiment concrete structure principle of the present utility model is described in further detail.

Fig. 1 is the surface structure schematic diagram of this novel safety cabinet.

Fig. 2 is the assembly structure schematic diagram (for a kind of keeper of positive stud structure) that four-way that gear drive is equipped with in the safe door inboard ties the anti-body of forcing open the door of lock more.

Fig. 3 is the structural representation that four-way that another kind is equipped with gear drive tiltedly ties lock pick-proof cabinet door.

Wherein: 1-cabinet, 2-cabinet door, 3-coded lock (password knob); the 4-handle (or claim handgrip, and small-sized safe door can not adorned handle), 5-pellet shot from a slingshot lockhole; 6-runners (being provided with steamboat); the 7-face, 8-keeper bolt seat (being the keeper of positive stud structure), 9-bolt; 10-connecting rod (push rod); the 11-connecting rod locating glooves, the 12-locating pin, 13-installs base plate (assembly plate); the 14-driven wheel; the movable tooth bar of 15-, 16-tooth bar installing rack, 17-block (can insert in the otch of coded lock slotted panel); the slotted panel of 18-coded lock; 19-slotted panel containment vessel (lid), the 20-pull bar (but driven gear rotating) of shaking hands, 21-pellet shot from a slingshot dead bolt (being provided with otch cooperates with block); 22-block (being provided with protruding button cooperates with the otch of pellet shot from a slingshot dead bolt); the 23-cylinder lock, the oblique bolt bolt of 24-seat, 25-tiltedly fastens with a bolt or latch.

With reference to accompanying drawing as can be known, the utility model also has following technical characterictic when specific design is made:

One, can make on the described four-way activity keeper bolt seat and be a bolt two door bolt structures, also can make and be a bolt three door bolt structure (see figure 2)s, can make like this lock after, make more firm that the cabinet door closes, especially for relatively large safety cabinet.

Two, described four-way activity keeper, its bolt seat and bolt can be installed on cabinet every body and arrange the keeper (see figure 2) that is positive stud structure, also can install to arrange to be along the keeper (see figure 3) of the oblique stud structure of diagonal.

Three, when manufacturing and designing the safety cabinet of big specifications and models, also can make and be employing the lock pick-proof cabinet door structure that ties of positive bolt and the oblique superimposed combination of bolt (is made existing positive bolt on the cabinet door, also oblique bolt arranged more, at this moment the tooth bar of An Zhuaning can be above four, figure is slightly), pick-proof effect that can the large-scale safe door of more effective raising.

Four, prize the coded lock knob (axle) and face in cabinet door front for fear of the thief after, prevent from effectively that coded lock is scattered because of slotted panel or drops to lose the insurance function, also be set with containment vessel in the periphery of coded lock slotted panel.

Compared with prior art, the utility model adopts multidirectional lock anti-picking devices that tie of gear drive because of its cabinet door more, Bolt around the door body is evenly distributed rationally, and manufacturing and assembly precision can reach desirable effect, have greatly improved The pick-proof performance. The coded lock slotted panel is provided with the Anti-scattering containment vessel, and rotation axis is prized, and still plays insurance function. In sum, this practicality newly has rational in infrastructure, and the installation accuracy height operates lightly, and its pick-proof performance more can reach The unapproachable excellent effect of general insurance cabinet.
