Abstract

Provided is a genuineness-forgery split type code lock which is mainly composed of a split typed code lock (1), split typed forge lock bodies (2) and a lock point linkage (3). Therein, one split typed code lock (1) and a plurality of split typed forge lock bodies (2) are arranged on the case body (4). A lock dial and a key are integrated into one dial key (11) which is separated from the lock body. In unlocking the door, the dial key (11) is inserted into the key hole (121) to unlock the door. The utility model which enhances the safety of the safe has a simple structure and is simple to use, maintain and repair.

Description

True and false split-type puzzle lock

Technical field

The utility model relates to a kind of mechanical code lock, and especially true and false lock is structured the formation on casing, and one of them is a split-type puzzle lock.

Background technology

Along with expanding economy, the social demand amount of strongbox increases day by day, the structure of commonly using strongbox mostly is to adopt metal cabinet, and a coded lock and one a lock point linkage handle usually is installed on casing, concerning stealer, be easy to just where know coded lock, with clearly defined objective, experienced stealer is usually adopted simple tool, adjust combination disk, the way of listening just can be opened strongbox rapidly.The problem that traditional strongbox exists in fact is: one has indicated the position of locking to stealer; Its two because combination disk and lock be for one, having indicated it to stealer is coded lock; Its three because the instrument of debugging password has been prepared in the existence of combination disk to stealer.At above-mentioned 3 points, traditional strongbox structure must be improved, and eliminates described 3 hidden danger, is the task of top priority.

Summary of the invention

According to background technology, the purpose of this utility model is to provide a kind of and on casing lock body and dial is made for chorista, dial is made the scale key that to adjust password of band scale, on casing, increase on the other hand and put a plurality of false lock bodies, true and false lock body outward appearance unanimity, the arbitrarily conversion of the position of true lock body can be inserted in the scale key on the true lock pin when unpacking, can unblank by traditional approach.

To achieve these goals, the utility model is realized according to following technical scheme:

A kind of true and false split-type puzzle lock, mainly by split-type puzzle lock (1), split type false lock body (2), lock point linkage (3) is formed, it is characterized in that: go up at casing (4) split-type puzzle lock (1) is installed, a plurality of split type false lock bodies (2) are installed, the lock core (12) of split-type puzzle lock (2) is inserted in the lock core cover (13), lock core cover (13) is fixed on the casing (4), spring (14) and two password locking plate B (16), be separated with packing ring (15) therebetween, be enclosed within according to the order of sequence on the lock core cover (13), password locking plate A (17) and lock core shaft (122) interconnect with pin (18), and lock core (12) is shaped on the keyhole (121) of trapezoidal shape, and scale key (11) can insert in the keyhole (121).

Owing to adopted technique scheme, the utlity model has following advantage and effect:

1, arranged true and false split-type puzzle lock on the utility model casing, made the robber be difficult for finding the real password lock, be provided with huge obstacle to theft;

2, the lock-bit on the utility model casing does not have dial, and dial has become key, is provided with huge obstacle to theft equally;

3, the utility model is simple in structure, reliable operation, and maintenance and repair are simple and easy.

Fig. 3 is the perspective exploded view of the utility model split-type puzzle lock

Among the figure: 1-split-type puzzle lock, 11-scale key, 12-lock core, 13-lock core cover, 131-draw-in groove, 14-spring, 15-packing ring, 16-password locking plate B, the 161-groove of unblanking, the 162-reversed column, 17-password locking plate A, 18-pin, 121-keyhole, 122-lock core shaft, the split type false lock body of 2-, 21-lock core body, 22-lock core cover, the 23-back-up ring, 24-pin, 3-pin point linkage, 31-rotating shaft, the 32-axle sleeve, 33-link rod, 34-nut, 4-casing

The specific embodiment

By Fig. 1, shown in Figure 2, the utility model is mainly by split-type puzzle lock 1, split type false lock body 2, lock point linkage 3 is formed, wherein: a split-type puzzle lock 1 is installed on casing 4, a plurality of split type false lock bodies 2 are installed, and the lock core 12 of split-type puzzle lock 2 is inserted in the lock core cover 13, and lock core cover 13 is fixed on the casing 4, spring 14 and two password locking plate B16, be separated with packing ring 15 therebetween, be enclosed within according to the order of sequence on the lock core cover 13, password locking plate A17 and lock core shaft's 122 usefulness pins 18 interconnect, lock core 12 is shaped on the keyhole 121 of trapezoidal shape, and scale key 11 can insert in the keyhole 121.

Shown in figure, the lock core cover 22 of split type false lock body 2 is fixed on the casing 4, lock core body 21 inserts and overlaps 22 shaft types by back-up ring 23 and pin 24 with lock core in the lock cores cover 22 and fix, and can overlap rotation 22 at lock core, and lock core body 21 heads are shaped on the keyhole 121 of the trapezoidal shape the same with lock core 12.

As seen from the figure, a lock point linkage 3 also is split type, ten can drive the purpose that link rods 33 come operable lock point interlock connecting rod to reach to open lock by scale key 11 rotating shafts 31 when unblanking.

By shown in Figure 3, be shaped on draw-in groove 131 on the lock core cover 13, be used for preventing the rotation of packing ring.It is identical with physical dimension to be shaped on physical dimension the unblank groove 161 identical with the position on two password locking plate B16 and the password locking plate A17, but the reversed column 162 that the position is different, in order to stir password locking plate B16 in certain position, reach three times to word, groove 161 alignment of unblanking of two password locking plate B16 and password locking plate A17 are unblanked.
