Description
One, technical field
The utility model relates to a kind of flat block-proofing lock and key.
Two, technical background
At present, the realization of mechanical field keyhole anti-clogging function mainly is to lean on the improvement of the following aspects to reach.1, protect anti-blocking class: be to add protector protection lockhole at common lockset, combination disk protection and simple mechanism protection are arranged, the combination disk protection need remember password and just can open, operation inconvenience and easily destroyed, and simple and mechanical protection can not be accomplished reliable protection.2, anti-plug-hole class: be that the key hole of common lockset lock core is made as through hole,, can not accomplish reliably anti-blocking so that be easy to after stifled remove.Under field extreme environments such as oil, mine, the place that artificial destruction is very serious, general lockset can't be accomplished effectively to resist to destroy at all,
Three, summary of the invention
Purpose of the present invention mainly is exactly to prevent in the open air artificial destructions such as lock core is blocked under the adverse circumstances, and invents several keys of a kind of flat block-proofing lock, is mainly used in the antitheft of the serious place of artificial destructions such as open-air storehouse, guard box, valve.
Technical scheme of the present invention realizes in the following manner:
Lock is made up of lock core, lock body and locking bar for cylindrical, connects together by screw thread and locking bar nut on the locking bar; Lock core is a cylindrical shape, on the thick circumference of barrel, be provided with on several little, big lockpin hole of diameter down of diameter, establish the different reducing lock pin of length in the hole, divide into the same reducing lock pin of length, on the inner periphery of lock core, be provided with the male thread coupling of box thread and locking bar upper end, on the excircle of lock core, be provided with several keyways; Lock body is a cylindrical shape, be provided with on the circumference of lock body wall thickness with lock core on the identical and corresponding locking tappet hole of lockpin hole number, in establish spiral snap.
Key by key cylinder, be located at the key cylinder center reducing knock pin, with the nut of jackscrew coupling, round key plate in the key cylinder and keyboard on lock pin forms, lean on the snap ring of male thread, bottom on reducing knock pin top and the nut on the key cylinder one that is connected; Key cylinder top circumference is provided with keyway number correspondent equal set on several keyboard keys and the keyboard circumference, set several lock core keys on the circumference of its underpart, with the keyway correspondent equal on the lock core, the nut of its upper end can or weld one with its processing one; The circumference of keyboard is provided with several and the key pin of the lock pin correspondent equal locked, and remaining space is provided with several positive stop lug boss after the distribution of key pin.Cooperate with keyway on the lock core by on the key lock core key between key and the lock, jackscrew presses down keyboard, and the key pin on the keyboard presses down the lock pin of different length, presses down snap rotary opening and closing lock by lock pin, on lock core lower plane and the lock body during plane contact for unblanking, do not open for lock when not contacting.
The different long lock pin of among the present invention several upper surface by the setting of dog chart, makes planar horizontal or out-of-level on itself and the lock core.Prevented that effectively booty from entering the snap place, it has been followed the string and compressibilty, the danger of having avoided lock pin not go up or do not open is one of advantage of the present invention.Two of the advantage key of unblanking is special, does not have it not lock or do not open, and is to utilize to rotatablely move directly to drive the function that the closing organ that is attached thereto is realized the switch of valve or Pithead preventing thieves case in the lock of lock or the process opened.Can be widely used under the field extreme environments such as oil field, mine the place that artificial destruction is serious.Can avoid theft effectively and destroy, prevent the loss of people's property and national wealth.

Five, the specific embodiment
With Fig. 1,2,3,4,5 is example, by embodiment technical scheme of the present invention is further set forth:
The present invention is made up of flat block-proofing lock and flat antiblocking lock key two parts, shown in Fig. 1,2,3,4,5.
Flat block-proofing lock comprises lock core 10, lock body 13 and locking bar 14.Lock core 10 is cylindrical, lock core 10 and lock body 13 are axially to be provided with up and down, and locking bar 14 is cylindrical, on have male thread,, box thread set on lock core 10 inner peripherys matches with the locking bar nut 15 that is located at lock body 13 lower ends, and lock core 10 and lock body 13 axially are connected one.
Flat antiblocking lock key, the nut 6 that comprises key cylinder 7, is located at the reducing knock pin 5 at key cylinder 7 centers, joins with jackscrew, be located at the round key plate 3 in the key cylinder 7 and be located at key pin 8 on keyboard 3 circumference, by the snap ring 4 of the male thread on reducing knock pin top, bottom and nut 6 on the key cylinder one that is connected.
The difference of the present invention and standard machinery lock is a rotational lock core 10 and fixing lock body 13 is layout up and down, plane contact, and lock pin 9,11 and snap 12 are axial arranged.Several lock pins and snap along the circumferential direction arrange, keyboard 3 key pins 8 move up and down with elongated lock pin 9 fixed length lock pins 11 same axis directions, lock core 10 and fixedly between the lock body 13 by fixed length lock pin 11 lockings.When unblanking, be enclosed within key cylinder 7 on the lock core 10 and turn an angle, lock core key 1 connects together key cylinder and lock core 10 by rotating lock pin side step groove, nut 6 connects together with key cylinder 7, rotate jackscrew bar 5, pushing keyboard 3 and key pin 8, keyboard 3 and key pin 8 move downward along positioning key 2, depress elongated lock pin 9, fixed length lock pin 11 is pushed into lock core 10 and lock body 13 plane that joins, key tube 7 promptly drove lock core 10 and rotated together this moment, thereby realized unblanking by the locking bar 14 that is fixed together with rotational lock core, drove interlinked mechanism realization folding locked object body.Snap ring 4 connects together clamping stagnation when preventing the keyboard rollback with keyboard 3 and jackscrew 5.
In addition, this lock core adopts the high-quality steel through appropriate heat treatment, destructions such as can fine resistance boring, saw, pound, this lock core rotating rod lock intensity height, functions such as mechanism's realization valve folding that can utilize its rotational motion directly to drive to be attached thereto, casing folding.
