Description

The button-type mechanical combination padlock

One, technical field:

The utility model relates to a kind of theft-preventing mechanical lock, particularly relates to being used for security door, safety cabinet the antitheft mechanical code lock on the strongbox.

Two, technical background:

Traditional marble mechanical lock exists a lot of shortcomings, and it is imitated for the people easily, particularly expertly adopts master-key in seconds just lockset can be opened, it prevents opening, antitheft, tamper-resistant function is relatively poor; Common coded lock exists then that confidentiality is strong, the orientation of unblanking is eavesdropped by the people easily and adopted the not difficult deficiency of technical opening lockset; Simultaneously electronic password lock exists and makes use cost height, fragile, the defective that easily cracks.

Three, summary of the invention:

The purpose of this utility model is to provide a kind of anti-master-key unlatching, anti-other technologies unlatching, effective button-type mechanical combination padlock of anti-eavesdrop of collecting.

The technical solution of the utility model is: include mainboard, traditional mechanical dead bolt, lock cylinder and digital controlling organization, button inter-locking panel and digital disk are slidingly installed on an axle sleeve, the center fixed positioning disk, the resetting shaft of being with the driving lever that resets is installed in the axle sleeve, form cipher control mechanism by digital disk, digital double-linked cam, forward and reverse mobile helical teeth cam, button, password interlock cam, form password unlocking mechanism by password unlocking cam, hyoplastron button, bolt plate.

Also include by button inter-locking panel, button inter-locking panel interlock plate, button inter-locking panel driving lever form by key box.

The utility model because cipher control mechanism is arranged, by key box, have the advantage that prevents to utilize feel and eavesdropping that password is untied.

Five, the specific embodiment:

As can be seen from Figure 1, it is the digital disc type of button of the present utility model, include mainboard 6, the mechanical dead bolt of tradition, lock cylinder 19 and digital controlling organization, on mainboard 6, be fixed with two axle sleeves, button inter-locking panel 13 and digital disk 1 are slidingly installed on axle sleeve 9, center fixed positioning disk 3, the resetting shaft 10 of being with the driving lever 11 that resets is installed in the axle sleeve 9, alarm switch 14 is housed on the button inter-locking panel 13, by digital disk 1, digital double-linked cam 2, forward and reverse mobile helical teeth cam 15, button, password interlock cam 16 is formed cipher control mechanism, digital disk evenly is divided into 10 five equilibriums, be 10 button figure cases, each button figure case is divided into 6 and is divided into the digital transposition usefulness of arranging, unblanking on the axle 20 password unlocking cam 22 to be housed, lock cylinder 19 is equipped with on the next door, password unlocking mechanism is by password unlocking cam 22 as can be seen from Figure 2, hyoplastron button 30, bolt plate 24 is formed, press key box as can be seen from Figure 3 by button inter-locking panel 13, button inter-locking panel interlock plate 27, button inter-locking panel driving lever 26 is formed, alarm switch 34 is housed on positioning disk 3 as can be seen from Figure 4, can uses by external alarm with alarm switch 14.

Fig. 5, Fig. 6 are another embodiments of the present utility model, be digital disk to be divided equally expand into digital strips, simultaneously the button inter-locking panel is changed to button interlock plate 37, just the circular motion of digital disk, button inter-locking panel has been become the rectilinear motion of digital bar 38, button interlock plate 37, all the other structures are the same with the digital disc type of button.

Two kinds of embodiment courses of work, principle are roughly the same, now explain as follows:

Password principle: after deciding password, will the forward identical with the password figure place moving the helical teeth cam is separately fixed on the calibration position of the corresponding digital keys of password, the forward of first password move the helical teeth cam on the first calibration position, to move the helical teeth cam be on the second calibration position for the forward of second password, just which calibration position the forward of which password moves the helical teeth cam on, again reverse mobile helical teeth cam is separately fixed at each button first, second, on the 4th, the 6th calibration position, then password setting finishes.

When changing password, pull down cottor pin 17, flat shim 18, digital disk 1, forward on the password figure position that will change respectively again and reverse mobile helical teeth cam fix by the requirement of establishing password just can change careful sign indicating number, installs by the anti-order of dismounting again.

Button interlocking principle: when button was unblanked in rotation, button inter-locking panel interlock plate 27 rotated button inter-locking panel 13, and button is pinned in its opening displacement, unclamped that button inter-locking panel 13 automatically resets when unblanking button; When the spinning reduction button, drive the driving lever 11 that resets and rotate, button inter-locking panel 13 rotates with the driving lever 11 that resets at this moment, and button is pinned in its opening displacement, unclamps reset button then, and button inter-locking panel 13 automatically resets, and can prevent to utilize feel and tapping device that password is untied.

The course of work: when locking behind the door, the then digital controlling organization of spinning reduction button will pin.When unblanking, the spinning reduction button resets digital disk, first forward is moved on the working position that the helical teeth cam places the first password figure button, key lever and forward move the moving sets that the helical teeth cam forms digital disk are moved a digital arcuate distance when pressing the first password figure button, thereby next forward is moved on the working position that the helical teeth cam places next password figure button, up to whole buttons of having pressed set password, at this moment rotate the password unlocking button, password interlock cam 16 is changed in the opening of digital double-linked cam 2 lock is opened; Also can directly lock be opened simultaneously with the key lock.

If the realization interlock function removes axle sleeve 21 and password unlocking axle 20, directly lock cylinder 19 is contained in axle 20 places of unblanking and just can realizes interlock function.
