The utility model is rational in infrastructure, compact, easily manufactured, the tooth decoding that the tooth be simultaneously provided with by key side and top side thereof are provided with, rotating key can drive unlocking mechanism to realize opening and closing, being positioned at lock core settles the concealment of blind hole front end decoding lockset to form by the second spring, the second pellet etc. the method unlatching cannot opened by conventional lock, practicality is stronger, and security reliability is higher.
Accompanying drawing explanation
Fig. 1 is that master of the present utility model looks sectional structure schematic diagram.
Detailed description of the invention
A kind of anti-technical opening cylinder lock, as shown in Figure 1, comprises lock body 1, lock core 2, opening and closing shifting block 3, first spring 5 and the first pellet 4, the lock core being communicated to its lateral surface is set in lock body 1 and settles blind hole, lock core settles blind hole rear end to extend to lock body 1 lateral surface so that the opening be provided with is exposed at lock body 1 lateral surface, lock core 2 is fitted in lock core and settles in blind hole and settle blind hole to move with rotation mode and lock core and coordinate, lock core annular caulking groove of assigning blind hole internal perisporium to arrange, opening and closing shifting block 3 is arranged in annular caulking groove and the torque drive produced by lock core 2 time rotational and moving with the mode revolved round the sun around lock core 2 and annular caulking groove coordinates, the key hole running through lock core 2 is set in lock core 2, it is corresponding out exposed from lock core 2 rear end face down to its key insert port be provided with from the exposed rear end face out of lock body 1 lateral surface that key hole rear end extends to lock core 2, arrange in lock body 1 and somely settle blind hole sidepiece to be communicated with key hole sidepiece the first spacing blind hole 6 that lock core settles blind hole and key hole from lock core, the first spring 5 is equipped with in each first spacing blind hole 6, the power that the contacts effect that the elastic force effect that the first pellet 4 associated with opening and closing shifting block 3 mechanical kilowatt that each first spacing blind hole 6 internal perisporium is equipped with produces towards the first straight line development length direction, spacing blind hole 6 place by the first spring 5 and key 10 sidepiece that inserts key hole produce towards the first spacing blind hole 6 place straight line bearing of trend and the first spring 5, key 10 sidepiece touches cooperation mutually and then can only pass in and out key hole in the mode of moving along the first spacing blind hole 6 place straight line bearing of trend and coordinate with the corresponding first spacing blind hole 6 is dynamic, also comprise the second spring 8 and the second pellet 9, at lock body 1, at its medial surface and lock core, to assign the position between blind hole to arrange some assigns blind hole front end to be communicated with key hole front end the second spacing blind hole 7 that lock core assigns blind hole and key hole from lock core, the second spring 8 is equipped with in each second spacing blind hole 7, the power that the contacts effect that the elastic force effect that the second pellet 9 also associated with opening and closing shifting block 3 mechanical kilowatt that each second spacing blind hole 7 internal perisporium is equipped with discharges towards the second spacing blind hole 7 length direction by the second spring 8 and key 10 head end that inserts key hole produce towards the second spacing blind hole 7 place straight line bearing of trend and the second spring 8, key 10 head end touches cooperation mutually and then can only pass in and out key hole in the mode of moving along the second spacing blind hole 7 place straight line bearing of trend and coordinate with the corresponding second spacing blind hole 7 is dynamic.
As shown in Figure 1, operating principle of the present utility model is: under the promotion of the tooth be provided with at key 10 side, it is concordant with outer lock core cylindrical that first row first pellet making to be positioned at the first spacing blind hole 6 and lock core 2 comprise internal cylinder, meanwhile, the tooth that key 10 top is provided with pushes away before first row second pellet being positioned at the second spacing blind hole 7, first row second pellet is pushed in the corresponding hole of opening and closing shifting block 3, until second row second pellet departs from opening and closing shifting block 3, and make second row second pellet concordant with internal cylinder top, then key 10 is rotated, second pellet 9 drives opening and closing shifting block 3, realize opening and closing of the present utility model.When extracting key 10 out, second pellet 9 is under the promotion of the second spring 8, pin opening and closing shifting block 3, like this when the utility model is by technology unlocking, even if first row first pellet is levelling, unlocked position is arrived due to the second pellet 9 cannot be made, opening and closing shifting block 3 still can not be rotated then by locked, though outer lock core is rotatable, because first row second pellet does not enter in opening and closing shifting block 3, lock core 2 and opening and closing shifting block 3 cannot be made to link, and opening and closing shifting block 3 also just can not rotate simultaneously.If the tooth height that the second pellet 9 and key 10 top are provided with can not match, first row second pellet runs through again interior outer lock core and opening and closing shifting block 3 simultaneously, and lock core 2 can rotate or dally.
