Abstract

The utility model discloses a sleeve type mechanical cipher lock, characterized in that a cipher component comprises three steel tubes with different diameters sheathed together. After sheathed together, the three steel tubes are sheathed on a rotation shaft. Each steel tube is provided with a secret code aperture and a shift fork button for checking codes. The rotation shaft is provided with a deflector rod and a secret code rod. An unlocking toggling piece is connected to the rotation shaft. After the secret code is arranged rightly, a handle is pulled to rotate. Thus, the lock can be unlocked. The utility model overcomes the shortcomings of great volume of the cipher lock, poor confidential performance and inconvenient opening.

Description

Sleeve type mechanical cipher lock

The utility model relates to a kind of bushing type mechanical code lock, and the occasion highly confidential for family, work unit and needs extensively is suitable for.

In the prior art, electronic password lock cost height needs power supply, and the scope of application is restricted; Safety cabinet is guaranteeing that with coded lock structure is huge under the condition of its intensity, and the scope of application also is restricted, and rotating shaft is in rotation, and whether password aligns, and staff can feel out that security performance reduces greatly; The patent No. is that 85200207 Chinese patent discloses a kind of coded lock, three locating wheels that have an opening and a rotating shaft that has notch are arranged as cipher component, can form three password numbers, in the sign indicating number process, if rotate with the light outer handle of have gentle hands, the 3rd password number can be felt out, and its password combination number of times is significantly reduced, and security performance also reduces greatly, the required precision height of especially this lock, technological requirement adopts powder metallurgy, thereby manufacture difficulty is big, the cost height.

The purpose of this utility model is that design is a kind of easy to manufacture, and the low and security performance of cost is strong and can extensively practical mechanical code lock.

This lock is by turning handle, dial, cipher component and unblank to pull out sheet and form.Cipher component is made up of sleeve pipe and rotating shaft, sleeve pipe is that the steel pipe socket by three different-diameters forms together, having a password opening and one on each steel pipe pulls out and turns round, its about side respectively has a circle to be used to settle the groove of tensioning steel wire, casing pipe sleeve has a dead man and a password bar in the rotating shaft in rotating shaft.The rotating shaft front end has a flat opening, along the opening vertical direction one aperture is arranged, when pulling out sheet so that unblank and being inserted in wherein and rotating shaft fix, pull out and have row's aperture on the sheet so that adjust its extension elongation, the rotating shaft other end is inserted in the turning handle, and plug with a latch, so that they can rotate synchronously.Dial and lock body are fixed together and with fixedly ailing is on door, turning handle is enclosed in dial annulus central authorities and can rotates and pull out to guarantee turning handle.Also be mounted with the resetting-mechanism that the rotating shaft of pulling out is resetted in the lock body, it is made up of the baffle plate that is fixed on catch, spring, the slide in the rotating shaft and be fixed on the lock tube.

She Ji coded lock directly links to each other with cipher component owing to unblank to pull out sheet, thereby does not need to join in addition handle in the manner described above, and it is convenient to open; Cipher component adopts bushing type, and not only security performance improves greatly, and can reduce volume, makes usage range more extensive, especially is fit to family and uses; The used sleeve pipe of cipher component can just directly process with type, thus easy to manufacture, cost is low.If cipher component adopts two groups of sleeve pipes to be connected in series, security performance can strengthen more.

Below in conjunction with embodiment shown in the drawings the utility model is explained in detail:

Fig. 1 is a kind of overall structure figure of bushing type mechanical code lock.

Fig. 2 is the structure chart of sleeve pipe.

Fig. 3 is a sleeve pipe series splicing mechanical cipher element.

With reference to Fig. 1, the bushing type mechanical code lock is by turning handle 12, dial 14, cipher component (comprising sleeve pipe 17, rotating shaft 13, dead man 10 and password bar 8) and unblank to pull out sheet 1 and form, cipher component and unblank to pull out sheet and be enclosed in the

lock tube

18,2 be adapter sleeve, is tightened in outside the lock tube.4 is catch, is fixed in the rotating shaft, and 5 is spring, and 6 is slide, and 7 is baffle plate, is fixed on the lock tube, and catch 4, spring 5, slide 6 and baffle plate 7 constitute the resetting-mechanism of rotating shaft.Unblanking to pull out sheet 1 is a sheet metal, has row's aperture above, and the rotating shaft front end has a flat opening, along aperture being arranged perpendicular to opening direction, be convenient to unblank to pull out when sheet embeds inject steady pin 3, pull out the aperture on the sheet 1 by unblanking, can adjust its extension elongation to adapt to the door of different-thickness.The sleeve pipe of composition cipher component as shown in Figure 2, it is formed with three steel pipes of different-diameter, having a password opening 19 and one on each steel pipe pulls out and turns round 20, it is to avoid wherein that the rotation of a pipe drives the rotation that another has aligned the steel pipe of password that its about side respectively has a circle to be used to settle the groove 9 of tensioning steel wire, the effect of tensioning steel wire.Three steel pipe sockets make them leave uniform minim gap to each other by the tensioning steel wire together, and then are enclosed within and have promptly constituted cipher component in the rotating shaft, and dead man 10 and password bar 8 are arranged in the rotating shaft.Rotating shaft is inserted in turning handle central authorities and fixing with latch 11, and turning handle is enclosed within dial annulus central authorities and can freely rotates and move forward and backward, and dial 14 usefulness screws 15 nails are on door.

In to the sign indicating number process, with hand turning handle 12 is rotated, rotating shaft 13 is also rotated thereupon, and pulling out of pipe turned round in dead man 10 was just stirred, pulling out of pipe turned round during the pulling out of interior pipe turned round and stirred, in the pulling out to turn round and stir pulling out of outer tube again and turn round of pipe, after the outer tube password aligns, changed course counter-rotating handle, the password of pipe aligns in making, just changing hands handle more again, the pipe password aligns in making, and handle at last reverses again, align the 4th password number, at this moment, the password opening of three pipes point-blank, and the password bar is over against the password opening, as long as pulling handle, rotating shaft just can be pulled out a segment distance (degree of depth of password opening), and the head of unblanking to pull out sheet embeds door lock immediately and stirs in the groove, and the turning handle door lock can be opened.After openhanded, rotating shaft is got back to the origin-location under the effect of its resetting-mechanism.

Fig. 3 has provided the series splicing mechanical cipher element made from sleeve type structure of the present utility model, and it is made up of two sleeve pipes up and down, and wherein a pipe is pipe initiatively, and another pipe is passive pipe.During to sign indicating number, the interior pipe of active pipe is stirred the interior pipe of passive pipe earlier, and the interior pipe of passive pipe is stirred the middle pipe of passive pipe, and the middle pipe of passive pipe is stirred the middle pipe of active pipe again, goes down successively, and the order of password appearance is by outside outer, main, among the master, in the quilt, by in interior, main.Because the password number increases, so security performance strengthens greatly.
