Technical Field
The invention belongs to the technical field of security protection, and particularly relates to a multi-threshold mechanical padlock method based on elasticity.
Background
In the field of warehouse management, the requirement that two or even more persons participate in opening a warehouse door is often met, and a single person cannot open the warehouse. Most of the existing multi-party padlock schemes are (N, N) unlocking schemes, wherein N is the number of warehouse padlocks and the number of persons in charge of the warehouse. Namely, N locks are hung on the warehouse, N warehouse responsible persons carry one key respectively, and the opening of the warehouse requires that all the N warehouse responsible persons arrive on the scene. However, in case of emergency, if one or more warehouse managers cannot arrive at the warehouse in time, the warehouse gate cannot be opened. Such a design has a lot of inconvenience in practical application.
The prior art has the following problems: in the actual operation of multi-party management of warehouses or storage boxes, different opening or management authorities are often required to be allocated to multiple warehouse managers. Furthermore, for the management of some hazardous chemicals, padlocks or devices with any electronics or components are often not available for safety reasons. Most of the existing multi-party padlock schemes do not consider the problem and are difficult to have universality.
Disclosure of Invention
To solve the problems set forth in the background art described above. The invention provides an elastic force-based multi-threshold mechanical padlock which has the characteristics of safety and convenience in use.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides the following technical solutions: the utility model provides a many kinds of threshold value machinery padlock based on elasticity, is including installation box 9, and the inside bottom mounting of installation box 9 has trapezoidal support 5, and the internal connection of trapezoidal support 5 has lever 4, and a side surface of lever 4 is provided with weight 7, and the bottom of weight 7 is provided with base 8, and one side of base 8 is connected with bayonet 6, and one side upper end that weight 7 was kept away from to lever 4 is provided with tray 3, and the upper end of tray 3 is provided with compression spring 2, and the upper end of compression spring 2 is connected with knob 1 gradually.
Specifically, the installation box 9 is of a hollow box structure, and one end thereof is installed on a door of a warehouse or a storage box.
Through adopting above-mentioned technical scheme, guarantee that installation box 9 installs convenient firm, reduce the cost of setting.
Specifically, the bayonet 6 is of a U-shaped frame structure, and the inner diameter of the bayonet 6 is larger than the width of the lever 4 and smaller than the width of the weight 7.
Through adopting above-mentioned technical scheme, guarantee that device bayonet socket 6 can block between lever 4 and weight 7 when not unblock, guarantee the stability that the device used.
Specifically, N sets of locks in the device are respectively fixed on the corresponding mounting box body 9 positions above N compression springs 2, N keys correspond to the locks, and N responsible persons respectively hold the locks. Assuming that the maximum elastic force that can be provided by the compression spring 2 plus its own weight is x newtons, the weight 7 is y newtons, and the tray 3 is z newtons, then the following conditions exist for this solution: x K + z > y, x (K-1) + z ≦ y. That is, only when at least K compression springs 2 are compressed to the bottom, the end where the weight 7 is located can be tilted, and when less than or equal to K-1 compression springs 2 are compressed to the bottom, the end where the weight 7 is located cannot be tilted;
the method also has the functions of adjusting and customizing the access structure: the method comprises the following steps:
the method can change the number N of key holders by changing the number of the compression springs, and can change the number K of threshold values required by the unlocking device by adjusting the difference value between the elastic force of the compression spring 2 and the gravity of the weight 7. Further, in the above assumption, the K compression springs 2 have the same maximum elastic force and gravity. In practical design, the K compression springs 2 have different maximum elastic forces by setting different maximum compression depths for different compression springs 2, so that key holders corresponding to the N compression springs 2 have different unlocking weights, different unlocking combinations are obtained, and design and adjustment of the access structure are realized.
By adopting the technical scheme, the applicability of the equipment is improved, and the convenience of unlocking is ensured.
Specifically, the specific examples are: when the device is responsible for the number of people N and is 3 the position, suppose that the biggest elasticity of compression spring 2 and the sum of gravity are x ox respectively, and the sum of gravity of weight 7 is y ox, and the gravity of tray 3 is z ox, has: x 2+ z > y, x + z < y. That is, the 3-bit responsible person has the same access weight at this time, and the unlocking scheme is the (2,3) threshold scheme. For convenience of description, the end of the compression spring 2 is the left side of the lever 4, and the end of the weight 7 is the right side of the lever 4. The method specifically comprises the following steps:
1. when the device is in a locking state, the right side of the lever 4 falls down and is buckled into the bayonet 6, and the bayonet 6 cannot be drawn out through the base 8 because the inner diameter of the bayonet 6 is larger than the width of the lever 4 and smaller than the width of the weight 7;
2. when the device needs to be unlocked, 2 or 3 of 3 persons in charge can unlock the corresponding lock by using a key, the progressive knob 1 is twisted to compress the spring 2 to the minimum length, the end where the weight 7 is located is tilted, the bayonet 6 can be drawn out at the moment, and the device is successfully unlocked;
3. when needs unlocking device, if only 1 person in charge uses the key to open the tool to lock that corresponds, the gradual knob 1 that twists makes compression spring 2 to minimum length, then can not make the end perk that weight 7 is located, bayonet socket 6 still can not be taken out this moment, and the unblock authority leads to the unable unblock of device inadequately.
The working principle and the using process of the invention are as follows: when the novel lock is used, N sets of locks are respectively fixed on the corresponding positions of the installation box body 9 above the N compression springs 2, N keys correspond to the locks, and N responsible persons hold the locks respectively. Assuming that the maximum elastic force that can be provided by the compression spring 2 plus its own weight is x newtons, the weight 7 is y newtons, and the tray 3 is z newtons, then the following conditions exist for this solution: x K + z > y, x (K-1) + z is less than or equal to y. Only K compression spring 2 at least are compressed to the bottom, just can make weight 7 place end by the perk, bayonet socket 6 breaks away from lever 4 simultaneously to can take base 8 out and carry out the unblock, be less than or equal to K-1 compression spring 2 and compressed the unable perk weight 7 place end then to the bottom, bayonet socket 6 can't break away from between lever 4 and the weight 7, base 8 can't take out and the device can't unblock.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
