Abstract

The utility model discloses an anti-decoding structure on a mechanical coded lock. The anti-decoding structure is characterized in that the anti-decoding structure on the mechanical coded lock comprises an anti-decoding sheet; a notch is arranged at each position, corresponding to each code button, on the anti-decoding sheet; a bulge is arranged at the lower of each code button; the notches on the anti-decoding sheet are used for clamping the bulges at the lower parts of the code buttons and preventing the code buttons from moving up and down. The invention also discloses the special anti-decoding sheet of the anti-decoding structure. The anti-decoding structure on the mechanical coded lock and the special anti-decoding sheet of the anti-decoding structure have the advantages of enhancing the anti-decoding function and improving the safety of the coded lock.

Description

Anti-structure and the anti-sheet that cracks of special purpose system thereof of cracking of password that mechanical cipher is locked

Technical field

The utility model relates to mechanical code lock technical field, is the anti-technology that cracks structure of password that mechanical cipher is locked specifically.

Background technology

Mechanical lock is a small-sized machine with machine components combination, and lockset is all comprised of a lot of password keys, and when pressing after password key, the gearing in lockset produces power transmission, realizes the cipher control of lockset.Only, after Password Input is correct, lockset could be opened.But on market, to be easy to utilize the fit-up gap of machine components be diastema to this conventional mechanical code lock, with feel, can find the set password of lockset, greatly affected the security performance of lockset.

Utility model content

The purpose of this utility model is to provide a kind of anti-function that cracks of password that strengthens, the anti-structure that cracks of password that the mechanical cipher of the safety of raising lockset is locked.

The utility model is achieved through the following technical solutions.

The anti-structure that cracks of password that a kind of mechanical cipher is locked, it is characterized in that: the anti-structure that cracks of password that described mechanical cipher is locked comprises the anti-sheet that cracks of password, anti-the cracking on sheet and corresponding to the place of each password key of password, be provided with breach, the bottom of each password key is equipped with projection, and the anti-breach cracking on sheet of password prevents moving up and down of password key for blocking the projection of password key bottom.

Described password prevents that cracking sheet is a surface plate, is provided with for the rectangle perforation through password key at the middle part of surface plate, on two long limits of rectangle perforation, is interval with described breach.

A kind of anti-anti-sheet that cracks of password that cracks structure of described password that is exclusively used in, it is characterized in that: described password prevents that cracking sheet is a surface plate, at the middle part of surface plate, be provided with for the rectangle perforation through each password key, on two long limits of rectangle perforation, be interval with for blocking password key and play the each password key of locking and control the position breach the same with dynamics that each password key is pressed.

The utility model compared with prior art has the following advantages.

By technical scheme described in the utility model, when Turning lockset turn-knob, the anti-sheet that cracks of password is passed forward under the transmission of lockset knob cam, the anti-breach cracking on sheet of password blocks the projection of password key bottom, password key can not be pressed, prevent moving up and down of password key, lock each password key in certain position, thereby it is the same with dynamics to control the position that each password key presses, effectively like this prevented from utilizing diastema gap to crack the defect of lockset password, strengthen password and prevented cracking function, improved the safety of lockset.

Accompanying drawing explanation

Fig. 1 is the anti-structural representation that cracks structure of password that the utility model mechanical cipher is locked;

Fig. 2 is the enlarged diagram of Fig. 1 at A place.

The specific embodiment

The password of the utility model mechanical cipher being locked below in conjunction with accompanying drawing prevents that cracking structure is described in further detail.

As shown in Figure 1, Figure 2, the anti-structure that cracks of password that the utility model mechanical cipher is locked, comprise the anti-sheet 1 that cracks of password, anti-the cracking on sheet 1 and corresponding to the place of each password key 2 of password, be provided with breach 11, the bottom of each password key 2 is equipped with projection 21, and the anti-breach 11 cracking on sheet of password prevents moving up and down of password key 2 for the projection 21 of blocking password key bottom.Wherein password prevents that cracking sheet 1 is a surface plate, is provided with for the rectangle perforation through password key at the middle part of surface plate, on two long limits of rectangle perforation, is interval with described breach 11.When Turning lockset turn-knob 3, the anti-sheet 1 that cracks of password is passed forward under the transmission of lockset knob cam, the anti-breach 11 cracking on sheet 1 of password blocks the projection 21 of password key bottom, password key 2 can not be pressed, password key 2 can not move up and down like this, thereby lock each password key 2 in certain position, and it is the same with dynamics to control the position that each password key 2 presses, effectively like this prevented from utilizing diastema gap to crack the defect of lockset password, strengthen password and prevented cracking function, improved the safety of lockset.Password key comprises button cap and button piece 22 in the drawings, and the anti-sheet 1 that cracks of password is positioned on lock frame 4.The special anti-sheet 1 that cracks of password of the utility model is surface plate, at the middle part of surface plate, be provided with for the rectangle perforation through each password key, on two long limits of rectangle perforation, be interval with for blocking password key and play the each password key of locking and control the position breach 11 the same with dynamics that each password key is pressed.

Claims

1. the anti-structure that cracks of password that mechanical cipher is locked, it is characterized in that: the anti-structure that cracks of password that described mechanical cipher is locked comprises the anti-sheet that cracks of password, anti-the cracking on sheet and corresponding to the place of each password key of password, be provided with breach, the bottom of each password key is equipped with projection, and the anti-breach cracking on sheet of password prevents moving up and down of password key for blocking the projection of password key bottom.

2. the anti-structure that cracks of password that mechanical cipher according to claim 1 is locked, it is characterized in that: described password prevents that cracking sheet is a surface plate, at the middle part of surface plate, be provided with for the rectangle perforation through password key, on two long limits of rectangle perforation, be interval with described breach.

3. the anti-anti-sheet that cracks of password that cracks structure of password being exclusively used in described in claim 1 or 2, it is characterized in that: described password prevents that cracking sheet is a surface plate, at the middle part of surface plate, be provided with for the rectangle perforation through each password key, on two long limits of rectangle perforation, be interval with for blocking password key and play the each password key of locking and control the position breach the same with dynamics that each password key is pressed.
