Description

Theftproof lock
Technical field
The utility model relates to door lock, particularly relates to theftproof lock.
Background technology
Safe-guard door lock is in the market all lock cylinder and blade lock core, the antitheft of them mainly changes the inner structure of lock, its internal construction is become increasingly complex, the difficulty that the anti-theft lock more present with common non-anti-theft lock core is unblanked adds much, but can't fundamentally solve antitheft problem, still there are some experts that unblank and insert lockhole unlatching door by foreign matter; Occur that some security doors block lockhole in lockhole front end with one piece of shelter now, and on theftproof lock, shell and interior axle dig a groove, engage with foreign matter again, the former is because shelter is in lockhole front position, the expert that unblanks still has way to be removed by shelter, carry out unlocking anti-theft lock by the skill of unblanking of self again, the latter's processing technology is more difficult, is therefore all difficult to effectively be promoted.
Summary of the invention
The utility model, for the shortcoming of theft-prevention structure processing technology complexity in prior art, provides theftproof lock.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
Theftproof lock, comprises lock core sleeve, is arranged on axle in the lock core in lock core sleeve, also comprises push rod, and push rod upper end is provided with pushing block, and in lock core, axle is provided with the first spacing hole, and push rod engages with the first spacing hole.Lock core sleeve, axle in lock core, push rod and relevant antitheft accessory are hidden in anti-theft door frame, push rod does not communicate with keyhole, people cannot visually see them, foreign matter inserts keyhole can not touch push rod, there is very strong disguise, engage with the first spacing hole by controlling push rod simultaneously, realize axle in lock core can not relatively rotate, only have after push rod is separated with the first spacing hole and unblank with key again, effectively prevent foreign matter to insert lockhole and carry out technology unlocking, ensure that the anti-theft effect of security door, first spacing hole processing technology is simple, facilitate production and processing.
As preferably, lock core sleeve is provided with the second spacing hole, and the aperture of the second spacing hole is more than or equal to the aperture of the first spacing hole, after the first spacing hole extends in the second spacing hole.In order to push rod can be made to pass through the second spacing hole, and engage with the first spacing hole.
As preferably, the second spacing hole is through hole, and the first spacing hole is provided with bottom.First spacing hole is not communicated with keyhole, prevents foreign matter to insert keyhole and unlatching burglar-proof door.
As preferably, also comprise the first fixed case, push rod is arranged in the first fixed case, is provided with limiting section in the middle of push rod, is provided with return spring between bottom limiting section and the first fixed case.Limiting section and the first fixed case bottom surface limit the displacement of return spring, and when removing anti-theft feature, return spring can effectively make push rod and the first spacing hole depart from.
As preferably, is provided with limiting section in the middle of push rod, be provided with return spring between bottom limiting section and the first fixed case, push rod lower end is holding section, and the hole depth of the second spacing hole adds that the hole depth of the first spacing hole is less than the length of holding section.The degree of depth that holding section length is greater than the second spacing hole adds the degree of depth of the first spacing hole, and push rod can be engaged with lock core sleeve.
As preferably, the first fixed case top is spacing cover plate, and spacing cover plate is provided with the 3rd spacing hole, and the diameter of the 3rd spacing hole is greater than the diameter on push rod top, and the 3rd spacing hole is less than the diameter of limiting section.The activity space of spacing cover plate restriction push rod, makes push rod can not eject the first fixed case, and affects the engaging effect of next push rod and the first spacing hole.
As preferably, also comprise drive unit, drive unit connects pushing block, and a width of pushing block and ejector pin contact is greater than push rod top end face diameter.Drive unit drives pushing block to rotate, and make pushing block promote push rod and engage with the first spacing hole, pushing block is larger than push rod top end face diameter with the face of ejector pin contact, makes pushing block promote the effect of push rod more obviously, can not because of inconsistent phenomenon.
The utility model is owing to have employed above technical scheme, there is significant technique effect: the first spacing hole and the second spacing hole are cylindrical hole, processing technology is simple, common drilling machine just can complete, and engaged with the first spacing hole by push rod, fit structure is simple, but anti-theft effect is obvious, only have after being separated with the first spacing hole by push rod by electronic telecontrol unlocking device and use corresponding key ability unlatching burglar-proof door again, theft-prevention structure disguise is high, is difficult to by technology unlocking.
