Description

The lock that a kind of safety factor is high

[technical field]

The present invention relates to lockset, relate in particular to a kind of lock that has than high safety factor.

[background technology]

The theftproof lock that existing safety factor is higher all has the comparatively internal lock cored structure of elaborate, and its cost and cost are all very high, and the lock core of lockset is destroyed easily.

[summary of the invention]

The present invention is directed to the defects of prior art, provide a kind of safety factor high lock, to strengthen the theftproof performance of lockset.

In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:

The lock that a kind of safety factor is high comprises: a pair of clamping plate, this is provided with several to installing hole to clamping plate; The array knob, every group of knob comprises the first knob and the second knob, this first knob and the second knob can be located in a pair of installing hole on the described a pair of clamping plate with rotating freely, equal inlay card has gear on the first knob and the second knob, and the mutual interlock coupling of two gears, one door-plate, described door-plate are located at a clamping plate side; One panel, the parallel clamping plate surface of being located at of this panel, panel is provided with through hole, and is provided with one group of cipher mark in bore periphery, and described the first knob penetrates the part that through hole on the panel and this knob protrude panel and is provided with the mark that points to cipher mark; Fixing or inlay card has a round platform concentric with gear on described the second knob, and a side is provided with a plane breach on the described round platform, and this plane breach rotation is during extremely with the clamping plate parallel sided, and the plane breach is concordant with the side of described door-plate.

Preferably, be installed in to be arranged with pinion in the gear on the first knob and/or to be installed in the gear on the second knob and be arranged with pinion, described pinion is connected with knob and gear inlay card respectively.

Preferably, also comprise a key, the part that this key and the first knob protrude panel is complementary, and is provided with on the key the mark that points to cipher mark.

As can be seen from the above technical solutions, the knob phase transmission of the present invention by two mutual interlocks namely reach lock purpose, structure is very simple.If panel is provided with M cipher mark, be provided with N group knob, password quantity so of the present invention will reach the Nth power of M.In addition, knob of the present invention can rotate arbitrarily, is difficult for damagedly, and relevant shell fragment buckle is not set in the lock core yet, can't differentiate from sound and obtain unlocking cipher, has very high safety factor.Further, the present invention also can change password by the pinion that is arranged in the gear, has further strengthened security performance and the Practical Performance of lockset of the present invention.

Fig. 1 is decomposition view of the present invention;

Fig. 2 is assembled view of the present invention;

Fig. 3 is that the present invention is set in the drive mechanism figure that knob cogs.

[specific embodiment]

The present invention is further detailed explanation below in conjunction with the specific embodiment.

Shown in Fig. 1 ~ 3, the lock that safety factor of the present invention is high has mainly comprised a pair of clamping plate 1, clamping plate 1 are provided with array installing hole 11, also comprise the array knob, every group of knob comprises the first knob 2 and the second knob 3, the first knob 2 of every group of knob and the second knob 3 are installed in one group of installing hole 11 on the clamping plate 1, and the first knob 2 and the second knob 3 can rotate freely at installing hole 11, inlay card has gear 4 on the first knob 2, inlay card has gear 5 on the second knob, gear 4 and gear 5 mutual interlock couplings, go back inlay card on the second knob or be fixed with the round platform 6 concentric with gear, a side is provided with a plane breach 61 on the round platform 6; Also comprised a door-plate 7, door-plate 7 is located at clamping plate 1 side; One panel 8, these panel 8 parallel clamping plate 1 surfaces of being located at, panel is provided with through hole 81, and is provided with one group of cipher mark, 82, the first knobs 2 in bore periphery and penetrates the part that through hole 81 on the panel 8 and this knob protrude panel and be provided with the mark that points to cipher mark 82.Rotate the second knob 3 and drive round platforms 6 and rotate, when the parallel sided of the plane of round platform 6 breach 61 and clamping plate, the plane breach is concordant with the side of described door-plate 7.

Above-mentioned the first knob and the second knob can lock on clamping plate by screw, also can be folded between the two clamping plates.

Referring to shown in Figure 3, as preferred embodiment of the present invention, be installed in and be arranged with pinion 9 described pinion inner edges in the gear 4 on the first knob and be connected with the knob inlay card, the pinion outer rim is connected with the gear inlay card.The present invention can also be sheathed pinion in the gear on the second knob, more or the first knob namely all be arranged with pinion in the second knob, the structure the present invention by sheathed pinion can change password easily.

As preferred embodiment of the present invention, also comprise a key, the part that this key and the first knob protrude panel is complementary, and is provided with on the key the mark that points to cipher mark.

Of the present invention unblank and shut principle be: rotary sleeve on the first knob key or directly rotate the first knob, 4 rotations of the first knob driven gear, again driven gear 5 rotations of gear 4, gear 5 drives the rotation of the second knob, and the second knob drives round platform 6 rotations, when the first knob rotates to certain position, the plane breach 61 of round platform 6 and the parallel sided of clamping plate, the plane breach is concordant with the side of described door-plate 7, this moment, lock was in opening, door-plate 7 can be opened, in case and round platform 6 rotates through this position, lock namely is in locking states.

When needing to change password, rotate first the first knob to the original password position, open again lock core, keep gear 4 and gear 5 motionless, gear 4 or gear 5 interior sheathed pinions 9 are taken out, then the first knob is revolved the new cipher mark of indicia point that makes on the knob, pinion 9 is inserted in again in gear 4 or the gear 5 again, at last lock is installed the replacing of namely finishing password, operate very simple and convenient.

The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
