Embodiment 1
[0050] see Figure 1 to Figure 16 , a safety device for mechanical key interlocking, comprising a lock body and a lock bolt, characterized in that: the lock body and the lock bolt are mechanical key interlocking structures;
[0051] ——The lock body includes a master key 1, a lock cylinder 2, a lock case 3, and a lock cylinder 9;
[0052] The master key 1 includes a handle part 1-1, and a disc part 1-2 fixedly connected with the handle part 1-1, and the bottom of the disc part 1-2 is provided with a straight groove 1-4, Two projections 1-3 are arranged symmetrically on the outer wall of the disc portion 1-2, and the connection line between the two projections 1-3 is in the same direction as the inline groove 1-4;
[0053] One end of the inner wall of the lock cylinder 2 is provided with a ring-shaped edge 2-2, and a groove 2-1 for accommodating two protrusions 1-3 is symmetrically provided on the annular edge 2-2; The inner diameter of -2 is smaller than the distance between ...

The invention relates to the technical field of mechanical locks, in particular to a safety device for mechanical key interlocking. The safety device comprises a lock body and a lock plug, and is characterized in that the lock body and the lock plug are of a mechanical key interlocking structure, wherein the lock body comprises a main key, a lock cylinder, a lock case and a lock core, and the lock plug comprises a lock-tongue arrange in the lock case, a lock-tongue pressing head, a lock-tongue pressing device and an auxiliary key; and when an auxiliary cylinder of the lock-tongue rotates to a lock-tongue groove embedded into the lock core, the connection between linear convex blocks of the lock core and two grooves of the lock cylinder is in a cross shape, and therefore the main key cannot rotate, and when the auxiliary cylinder of the lock-tongue rotates to the other arc surface groove and is opposite to the lock-tongue groove of the lock core, the main key can drive the lock core to rotate until the two convex blocks of the main key correspond to the two grooves of the lock cylinder, and the main key can be pulled out at the moment. Compared with the prior art, the safety device for the mechanical key interlocking has the advantages of being small in size, high in safety coefficient, easy in installation and use, reliable in work and low in cost.
Description
technical field [0001] The invention relates to the technical field of mechanical locks, in particular to a safety device for mechanical key interlocking. Background technique [0002] At present, people pay more and more attention to industrial safety, and there are more and more technical means to solve industrial safety problems, but there are still many improvements and deficiencies in industrial safety door locks. [0003] Traditional industrial door locks either do not have an interlock function, or are not suitable for industrial environments such as unsuitable or expensive electrical components, limited space arrangements, and explosion hazards. Therefore, it is necessary to invent a mechanical key interlock safety device with small size, high safety factor, simple installation and use, and reliable operation. Contents of the invention [0004] The object of the present invention is to overcome the shortcomings of the prior art and provide a mechanical key interlo...
