Description

Multi-threshold mechanical padlock method based on elasticity

Technical Field

The invention belongs to the technical field of security protection, and particularly relates to a multiparty threshold mechanical padlock method based on elasticity.

Background

In the warehouse management field, there is often a need that two persons participate in the warehouse to open the warehouse gate, and a single person cannot open the warehouse. The current multiparty padlock schemes are mostly (N, N) unlocking schemes, wherein N is the number of warehouse padlocks and the number of warehouse responsible persons. The warehouse is hung with N locks, N warehouse responsible persons carry a key respectively, and all the N warehouse responsible persons are required to arrive at the scene for opening the warehouse. However, if any one or more warehouse responsible persons cannot arrive in time in case of emergency, the warehouse gate cannot be opened. Such designs present a number of inconveniences in practical applications.

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 often need to be assigned to a plurality of warehouse responsible persons. Furthermore, for the management of some hazardous chemicals, a padlock or device with any electronic equipment or components is often not employed for safety reasons. Most of the current multi-party padlock schemes do not take this into consideration, and are difficult to be universal.

Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Referring to fig. 1-3, the present invention provides the following technical solutions: the utility model provides a multiparty threshold value machinery padlock based on elasticity, includes mounting box 9, and mounting box 9's inside bottom mounting has trapezoidal support 5, and trapezoidal support 5's internal connection has lever 4, and one side surface of lever 4 is provided with weight 7, and weight 7's bottom is provided with base 8, and base 8's one side is connected with bayonet socket 6, and lever 4 keeps away from weight 7's one side upper end and is provided with tray 3, and tray 3's upper end is provided with compression spring 2, and compression spring 2's upper end is connected with progressive knob 1.

Specifically, the installation box 9 adopts 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 setting cost.

Specifically, the bayonet 6 adopts 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, ensure that bayonet socket 6 can block between lever 4 and weight 7 when not unblock of device, guarantee the stability that the device used.

Specifically, N sets of locks in this device are fixed respectively in the installation box 9 positions that N compression spring 2 top corresponds, and N is corresponding the key with the tool to lock, has N responsible person to hold respectively. Assuming that the maximum elastic force that the compression spring 2 can provide plus its own weight is x n, the weight of the weight 7 is y n, and the weight of the tray 3 is z n, the following conditions exist for this solution: x is K+z > y, x is (K-1) +z.ltoreq.y. Namely, only if at least K compression springs 2 are compressed to the bottom, the end of the weight 7 can be tilted, and if less than or equal to K-1 compression springs 2 are compressed to the bottom, the end of the weight 7 cannot be tilted;

the method can change the number N of key holders by changing the number of the compression springs, and can change the threshold number K required by the unlocking device by adjusting the difference value between the elasticity of the compression springs 2 and the gravity of the weights 7. Further, in the above assumption, the K compression springs 2 have the same maximum elastic force and gravity. In practical design, the invention can set different compression maximum depths for different compression springs 2, so that K compression springs 2 have different maximum elasticity, and key holders corresponding to N compression springs 2 have different unlocking weights, and further different unlocking combinations are obtained, thereby realizing the design and adjustment of an access structure.

By adopting the technical scheme, the applicability of the equipment is improved, and the unlocking convenience is ensured.

Specifically, specific embodiments are as follows: when the device is responsible for the number of people n=3, assuming that the sum of the maximum elastic force and the gravity of the compression spring 2 is x N, the sum of the gravity of the weights 7 is y N, the gravity of the tray 3 is z N, and the device comprises: x+z > y, x+z < y. Namely, at the moment, 3 responsible persons have the same access weight, and the unlocking scheme is a (2, 3) threshold scheme. For convenience of description, the end of the compression spring 2 is left of the lever 4, and the end of the weight 7 is right 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 pulled 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 is required to be unlocked, any 2 or 3 positions of 3 responsible persons use keys to open corresponding locks, the progressive knob 1 is twisted to enable the compression spring 2 to be the minimum length, the end of the weight 7 is tilted, the bayonet 6 can be pulled out, and the device is successfully unlocked;

3. when the unlocking device is needed, if only 1 responsible person uses a key to unlock the corresponding lockset, the progressive knob 1 is twisted to enable the compression spring 2 to be at the minimum length, the end where the weight 7 is located cannot be tilted, at the moment, the bayonet 6 still cannot be pulled out, and the unlocking authority is insufficient, so that the device cannot be unlocked.

The working principle and the using flow of the invention are as follows: when the invention is used, N sets of locks are respectively fixed on the corresponding positions of the mounting boxes 9 above the 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 the compression spring 2 can provide plus its own weight is x n, the weight of the weight 7 is y n, and the weight of the tray 3 is z n, the following conditions exist for this solution: x is K+z > y, x is (K-1) +z.ltoreq.y. Namely, only if at least K compression springs 2 are compressed to the bottom, the end of the weight 7 can be tilted, meanwhile, the bayonet 6 is separated from the lever 4, the base 8 can be pulled out to unlock, the end of the weight 7 cannot be tilted if less than or equal to K-1 compression springs 2 are compressed to the bottom, the bayonet 6 cannot be separated from between the lever 4 and the weight 7, the base 8 cannot be pulled out, and the device cannot be unlocked.

Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
