Problems solved by technology

[0002] For many years, the anti-theft problem of logistics equipment such as railway boxcars and containers has not been solved, and the so-called "lead blockade" that only has a handover function and no anti-theft function is still used; Measures, but have not been able to find a reusable anti-theft lock; the cost of common spring locks that are often used is much higher than the cost of the lock itself, and most of them are discarded after arriving at the destination. Vulnerable to damage and not seen in use; the reason why there are no locks for railway boxcar doors and container doors is that there are currently no door locks suitable for logistics equipment
Luggage combination locks and hanging combination locks are simple in structure and easy to operate and have a wide range of applications but poor confidentiality; although the mechanical combination lock cylinder with traditional roulette structure has better security, it has higher requirements for operators. The scope of application is limited, and it is quite difficult to increase the number of passwords, and the problem of limited number of passwords is difficult to solve; the push-button combination lock cylinder and the telephone dial-type full-mechanical combination lock cylinder also have better confidentiality, and the number of password digits and operability There has also been some progress in this aspect, but the lock cylinder has not been more widely used. The fundamental reason is that the external digital dial and buttons limit the scope of application of the lock cylinder to the indoor environment.
At present, there is no lock cylinder of a mechanical combination lock with a built-in digital disk, good security, easy increase of password digits and suitable for outdoor use.

Embodiment 1

[0048] Embodiment 1 takes the coded lock cylinder of the six-digit hexadecimal dial 24 as an example.

[0049] As shown in Figure 1 and 2, a hexadecimal coded lock cylinder with six digital dials 2 has 16777216 states (i.e. 16 to the 6th power); method for encoding; when decoding, the universal key is inserted into the keyhole, and the digital disc 2 is decoded one by one by using the clear feel produced by inserting the stepping steel ball 11 into the stepping hole 72 of the key. The installation frame 5, the six digital disks 2 and the pressure plate 6 stacked on the rotating core 1 in turn are riveted into one body with four rivets. Before riveting, the two ends of the rotating shaft 61 of the lever plate 4 need to be inserted into the mounting holes at the corner of the mounting frame 5 and the pressure plate 6, and the spring clip 8 and the spring 9 are installed; In the U-shaped notch 41 on the plate 25; the coding pin 7 is inserted in a certain coding hole on the rotat...

Embodiment 2

[0057] Embodiment 2 is an example with an eight-digit hexadecimal combination lock cylinder.

[0058]There are 4,294,967,296 million states in the eight-digit hexadecimal coded lock cylinder; the difference from the six-digit hexadecimal lock cylinder in Embodiment 1 is that a two-digit digital disk is added, but three key components have changed: one is eight The six-digit hexadecimal rotary core has increased two digits on the basis of the six-digit hexadecimal rotary core, and the length of the eight-digit rotary core body has increased the size of the thickness of two digital disks compared with the previous embodiment; There are 8 rollers 27 on the code roller shaft, and the length of the roller shaft has also increased the thickness of two digital dials; the third is that two step holes 71 have been added on the key, and its length has also been lengthened accordingly; in addition, the lever plate The widening of and the dimensional changes of the remaining parts are all...

Embodiment 3

[0059] Embodiment 3 takes a six-digit twelve-digit combination lock cylinder as an example.

[0060] There are 2,985,984 states in the lock core of the six-digit twelve-digit number disc; its external structure is similar to the combination schematic diagram of the steel ball combination lock core shown in Figure 1, and only two parts are different: the one is that the twelve-digit turntable 24 is the same as that in embodiment 1. Image 6 The difference of the shown turntable 24 is that the number of coding holes has changed from 16 to 12, and the coding serial numbers are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B twelve digits, and the turntable The graduation of 20 graduations has become 16 graduations by 20 graduations; The 2nd, the graduation of 12-digit separating plate 25 is the same as in embodiment 1 Figure 7 The difference of the shown separating plate 25 is that its number of divisions has changed from 20 divisions to 16 divisions, and the number of corresponding code ste...

Abstract

The invention relates to a steel ball password lock core of a plug-in inner overlapping digital disk, which is characterized by comprising a rotating core, a mounting frame, at least two digital disks and a connecting press plate, wherein the mounting frame, the digital disks and the connecting press plate are sequentially overlapped and penetrated through the rotating core; a lever plate is installed between the mounting frame and the connecting press plate, and a spring which is fixed on the mounting frame pulls a limiting rod of the lever plate; a code relay roller is clamped between the digital disks and the lever plate which are overlapped, a roller shaft is embedded in a U-shaped notch of isolating plates of the digital disks, and a roller is embedded among the isolating plates and rolled on rotating disks of the digital disks; each rotating disk is provided with a coding hole, and a coding pin is plugged into one of the coding holes. The digital disks are built-in and indestructible; the 10-30 system can be selected, and the digit can be arbitrarily selected between 2 and 12. The invention has sufficient password digit, good confidentiality, simple structure, strong adaptability and high reliability and is widely used for a vault, national defense, public security and a safety box and particularly applied to logistics equipment, such as railway wagons, containers, and the like.

Description

technical field [0001] The invention relates to a lock core of a mechanical coded lock, in particular to a steel ball coded lock core with a plug-in inner digital disc. Background technique [0002] For many years, the anti-theft problem of logistics equipment such as railway boxcars and containers has not been solved, and the so-called "lead blockade" that only has a handover function and no anti-theft function is still used; Measures, but have not been able to find a reusable anti-theft lock; the cost of common spring locks that are often used is much higher than the cost of the lock itself, and most of them are discarded after arriving at the destination. It is easy to be destroyed and not used by people; the reason why the railway box car door and the container door are unavailable without locks is that there is no door lock suitable for logistics equipment at present. Through the application environment analysis and on-site inspection of logistics equipment such as rai...
