Example Embodiment

[0039] Example 1

[0040] Such as Figure 2~8 The mechanical lock of the present invention shown includes a key with a password 1, a lock shell 2, a lock core 3, a movable column 4, a decoding plate 6, a compression spring 7, a retaining ring 8, a compression plate 9, a return spring 10 and a bolt drive Mechanism 11; Construct a key 1 with a code, and a cluster of movable posts 4 that contact the key 1 and transmit the code. The movable posts 4 are installed in the movable post mounting holes 3.2 on the lock cylinder 3, and the lock cylinder 3 is installed in the lock In the shell 2, the movable pillar 4 is provided with a decoding gap 4.1 for transmitting the password, and a decoding board 6 is provided at the upper end. The decoding board 6 is provided with a decoding hole 6.1 that allows the movable pillar 4 to pass through. The shape allows the movable column 4 to vertically pass through and the decoding gap 4.1 to move laterally within it. All the movable columns 4 pass thro...

[0043] Example 2

[0044] Figure 9-13 It is a structural form in which the decoding notch on the movable column is replaced with a blade notch in Embodiment 2 of the present invention. In this structure, a blade is provided on the movable column 4, and the blade has a decoding notch 4.1, such as Picture 11 As shown, it corresponds to the shape of the decoding hole 6.1 on the decoding board 6, and the corresponding movable column mounting hole 3.2 on the lock cylinder 3 also changes with the shape of the movable column 4.

[0045] The description of the features in this embodiment similar to that in Embodiment 1 is omitted here. It can be understood that the places where these features are quoted, and the places that are not clearly identified or described in this exemplary embodiment, the features Similar to the description above.

Example Embodiment

[0046] Example 3

[0047] To correctly decode and unlock the mechanical lock of the present invention, it is necessary to axially move all the movable posts 4 at one time, and make each movable post 4 have the correct position, and each movable post 4 has a compression spring 7 with the same elastic force and has Activity columns 4 of the same quality; theoretically, the only possibility for the technology to be opened is that people or instruments perceive the resistance and sound changes produced when each activity column 4 moves, in order to completely eliminate the theoretical possibility and practical operation of obtaining a password through monitoring Sex, combined Figure 14-18 To explain how the mechanical lock of the present invention is realized in structure: firstly, each movable column 4 can be provided with an interference slot 4.2 with more position than its position value, and another interference spring assembly 5 can be installed on the lock cylinder 3. In the i...

Abstract

The invention relates to a technical opening preventing mechanical lock comprising a lock case, a lock cylinder and a password carried key. The cylindrical lock cylinder capable of rotating and moving in the lock case is constructed. When a right key is inserted into a key hole of the lock cylinder, place values passed by decoding teeth on the key enable all decoding gaps on movable columns to be in the same horizontal plane, and when the decoding gaps are in decoding holes of the decoding plate, the lock cylinder moves relative to the decoding plate. The lock cylinder is engaged with a lock tongue driving mechanism, and then the lock tongue driving mechanism drives the lock tongue to finish lock opening or lock closing. According to the mechanical lock, technology opening preventing is achieved through a novel structure conception. Monitoring to a secret key is further precisely disturbed by using disturbing springs, and difficulty of technical opening of the mechanical lock is increased. The super large secret key amount prevents the attempt to open the lock. A key structure A and a key structure B are used, so that the using range of the mechanical lock is widened. The mechanical lock is less in part, convenient to use and capable of being applied to anti-theft mechanical locks in various using occasions such as outside hanging and inside installation.

Description

Technical field [0001] The invention belongs to the field of mechanical locks, and specifically relates to a mechanical lock that prevents technical opening Background technique [0002] At present, the amount of mechanical locks at home and abroad is large and extensive. Although the existing mechanical locks have a wide variety of different shapes and structures, and the internal structure of the lock cylinder is becoming more and more complex, the technical principles of most mechanical locks are not essentially different. From the perspective of preventing technical opening, the information engineering encryption and decryption principle is used to develop the restrictive relationship between the lock core components to prevent the leakage of information during the operation of the lock core components, so as to avoid the information leakage during the operation of the lock core components, resulting in comparison The result of easy technical opening. [0003] The public safet...
