Abstract

The invention relates to the field of short-term coded locks, in particular to a non-electric binary short-term coded lock which comprises a cross beam, salient points, coded sliding blocks, safety rings and the like, the number of the coded sliding blocks corresponds to that of the salient points fixed on the cross beam, and when the coded sliding blocks slide in the correct direction, the safety rings are fixed on the cross beam. The convex point can smoothly pass through the hole formed in the sliding block body only when the sliding blocks slide towards the correct direction, and the cross beam can be smoothly pulled away from the safety ring to achieve the unlocking purpose only when all the sliding blocks slide towards the correct direction. The coded lock is mainly used for guaranteeing the safety of goods within a short time and in a short distance, such as take-out, and the leakproofness and safety of the goods can be greatly improved due to the increase of the password digits.

Description

Technical Field

[0001] The invention relates to a short-term password lock, in particular to a binary password lock which does not require the use of electronics. Background Art

[0002] There are two main types of password locks on the market. One is an electronic lock that uses batteries to ensure energy supply. It has powerful functions and can be unlocked not only by fixed passwords, but also by fingerprints, face recognition, NFC sensing, etc. The other type of password lock is a simple mechanical lock that needs to be unlocked with a fixed mechanical key.

[0003] Although electronic combination locks are powerful, they require batteries as a continuous supply of energy. Once the battery is exhausted, there is no way to unlock the lock. In addition, mechanical locks require an external mechanical key to be inserted to unlock the lock. The disadvantage of separating the key and the lock body brings some inconvenience, and the key to unlock the lock cannot be transferred or shared. Summary of the invention

[0004] In order to solve the safety problems of goods in a short time and over a short distance, such as food safety and sealing problems of take-out boxes, and safety problems of express delivery, the present invention provides a non-electric short-term password lock with binary characteristics. This password lock can solve the sealing safety problems of goods in a short time and over a short distance because of the long time required for password matching, no need for battery supply, and low cost.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a non-electric binary short-term password lock, including a relatively long cylindrical crossbeam, on which ten spherical convex points are arranged to catch wrong password sliders. A slider that slides up and down is arranged on the left side of each convex point (taking the crossbeam pulling to the left to unlock as an example), such as sliding up for password 0 and sliding down for password 1 (0 and 1 are just considered as settings, and can also be other numbers). There is a hole slightly larger than the convex point at the position of the slider corresponding to the convex point in the sliding direction of the correct password, so that the convex point can pass through the hole smoothly when the password direction is correct. A total of ten convex points correspond to ten corresponding slider holes. Only when all ten sliders move smoothly in the correct direction can the ten convex points pass through the hole at the same time, so that the crossbeam can be smoothly pulled to the left to achieve the purpose of unlocking.

[0006] The beneficial effect of the present invention is that the purpose of protecting goods from external interference and damage can be achieved by setting corresponding passwords. While greatly reducing costs, the relative stability of short-term and short-distance goods is also achieved. At the same time, the corresponding passwords are also shareable and transferable, and can be circulated through text records, social media, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0012] [Example]

[0013] Figure 1 In the process, pull the cylindrical crossbeam 1 to the left to get out of the range of the safety ring 22, which is considered to be unlocked successfully. 2.4.6.8.10.12.14.16.18.20 is a password slider that can move up and down. Suppose the password slider slides up (such as 4.8.12.16.20) for password 0, and slides down (such as 2.6.10.14.18) for password 1. Therefore, when designing and manufacturing the slider, it is necessary to determine whether to set a hole on the upper or lower part of the slider that allows the protrusion to pass smoothly to the left based on the slider's password (sliding direction). For example, if the password of slider 2 is 1 to slide downward, a hole should be set on the upper part of slider 2. So when Figure 1 When the password is designed, the password is 1010101010. When the user pushes the slider in the corresponding direction according to the correct password, the 10 protrusions (3.5.7.9.11.13.15.17.19.21) fixed on the beam 1 can smoothly pass through the hole, allowing the beam 1 to leave the safety ring 22 for sealing, thereby achieving the purpose of unlocking.

[0014] Figure 1There are ten convex dots fixed on the crossbar, which means that the combination lock requires a ten-digit password to unlock. If there are nine convex dots fixed on the crossbar, it corresponds to a nine-digit password to unlock, and so on. When one slider and one convex dot are set, only two password attempts (0 and 1) are required to successfully unlock; when two sliders and two convex dots are set, four password attempts are required to successfully unlock; when three sliders and three convex dots are set, eight password attempts are required to successfully unlock; and so on, when ten sliders and ten convex dots are set, 1024 password attempts are required to successfully unlock. More sliders and convex dots can also be set to increase the difficulty of cracking the password.

[0015] The "short-term" in the non-electric binary short-term password lock means that the limited sliders and protrusions can be used to try out the password by exhaustively enumerating all passwords, so the time is relatively short. The time to crack the password becomes exponentially longer as the number of sliders and protrusions increases. When the password has fewer digits, the operator can successfully unlock it by exhaustively enumerating all passwords in a shorter time, while when the password has more than six digits, the operator often needs more time and patience to exhaustively unlock. The time that goods that are in short-term and short-distance traffic stay in the hands of the operator is relatively limited, especially for takeout, so the safety risk of goods with more than six digits, especially ten-digit password locks, is minimal, thereby achieving the purpose of protecting the sealing, integrity and safety of the goods.

A non-electric binary short-term password lock, consisting of 1.2.3.4.5.6.7.8.9.10.11.12.13.14.15.16.17.18.19.20.21.22 (see Figure 1), characterized in that: The 1 refers to the crossbeam, the 2.4.6.8.10.12.14.16.18.20 refer to password sliders that can move up and down, the 3.5.7.9.11.13.15.17.19.21 refer to spherical protrusions fixed on the crossbeam 1, and the 22 refers to a safety ring that fixes the crossbeam 1.

2. The crossbeam according to claim 1, characterized in that It does not have to be a cylinder, it can be a cuboid or other shapes as long as it meets the function.

3. The password slider 2.4.6.8.10.12.14.16.18.20 as claimed in claim 1, characterized in that: The number of the password sliders is the same as the number of the corresponding protrusions fixed on the beam, ensuring that one protrusion corresponds to one password slider. The distance that each password slider slides up and down can be flexibly designed and determined, so as to ensure that the protrusion passes through the hole smoothly when the password direction is correct. At the same time, the distance between the sliders can be flexibly determined according to the length of the beam. Similarly, the distance between the protrusions and the distance between the protrusions and the corresponding sliders can also be flexibly determined.

4. The password slider and the protrusion according to claim 1, characterized in that: The number is not fixed at ten, and can be flexibly adjusted as needed. When the number of password digits is more, that is, the number of password sliders and raised dots increases, the password difficulty is higher and the time to decipher is longer.

5. The spherical protrusion according to claim 1, characterized in that: It is fixed on the beam and connected to it, and can be changed into other shapes for use.

6. The safety ring 22 according to claim 1, characterized in that: When the password slider does not slide completely in the correct direction, the fixed crossbeam 1 plays a sealing role, so the shape and size can be adjusted.
