Abstract
The utility model relates to a technical unlocking-preventing lock, wherein a lock cylinder is sectioned into multiple components along an axis, at least one component is a sliding cylinder and at least one component is a rotating cylinder; multiple pin tumbler holes provided with internal and external pin tumblers and springs are arranged on each sliding cylinder and rotating cylinder; and the sliding cylinder consists of a sliding cylinder front section, a sliding cylinder rear section and a compression spring clamped between the two sections. The rear end of the sliding cylinder can extend into the inner cavity of a lock body; when the compression spring is not under the forward external force, a rotary locking pin on the sliding cylinder rear section is just inserted into a clamp opening inside the lock body; and when the compression spring is under the forward external force, the rotary locking pin on the sliding cylinder rear section is released from the clamp opening inside the lock body. The lock cylinder structurally adopts two-stage unlocking, only after the first-stage unlocking is performed by the key to release the rotary locking pin, can the sliding cylinder rotate, and the second stage is that the rotating cylinder can only rotate when the key is in the right place. The technical unlocking-preventing lock has the characteristics of technical unlocking and violent unlocking prevention.
Description
Technical field
The utility model relates to lockset, particularly the lockset of safe anti-technical opening.
Background technology
Existing lockset is comprised of lock ﹠ key.Lock is comprised of the lock body that is slidingly matched and lock gall again.
Arrange (or in-lines to having on lock body and the lock gall more, or arc shooting) marble hole, spring and upper and lower pellet are contained in the marble hole, when original key does not insert, misplace between the contact surface of the contact surface of upper and lower pellet and lock body and lock gall, therefore, lock gall is in the position that is prevented from turn, and can not unblank this moment.After original key inserted, the contact surface of the contact surface of upper and lower pellet and lock body and lock was in same position, and lock gall is in automatically turn position, turn this moment key drives the lock gall turn, the dead bolt plectrum of fixing on the lock gall, stir dead bolt, make the dead bolt retraction, finish the process of unblanking.
But above-mentioned existing lockset can not prevent technical unlocking, and exist theftproof performance relatively poor problem.As use master key or tinfoil instrument or other powerful unlocking tool all can make its unlatching.
The utility model content
The purpose of this utility model provides the lock of the good anti-technical opening of a kind of theftproof performance.
This novel purpose is achieved in that a kind of lock of anti-technical opening, comprise lock body, the lock gall that its front end stretches out, is rotatably assorted with the lock body inner chamber from the lock body inner chamber, described lock gall dissects along axis and is a plurality of assemblies, having an assembly at least is the slip courage, and to have an assembly at least be the turn courage, and be provided with a plurality of marble holes on each slip courage and the turn courage, and interior pellet, outer pellet and spring are housed in each marble hole successively; Described lock body inner chamber can be stretched in slip courage rear end, and the slip courage is comprised of slip courage leading portion, slip courage back segment and the Compress Spring that is clipped between the two; Be fixed with the rotation lock rationed marketing on the slip courage back segment, oriented open front formula bayonet socket on the flange of lock body inner chamber front portion, when Compress Spring is not subjected to the external force of forward direction, rotation lock rationed marketing on the slip courage back segment just in time is inserted on the interior bayonet socket of lock body, when Compress Spring is subject to the external force of forward direction, deviate from the bayonet socket of rotation lock rationed marketing in lock body on the slip courage back segment.
Above-mentioned all slip courage leading portions and all turn courages are fixed together.
Above-mentioned all slip courage leading portions and all turn gallbladder channel jump rings are fixed together.
It is two assemblies that above-mentioned lock gall dissects along axis, and one of them assembly is the slip courage, and another assembly is the turn courage.
It is 4 assemblies that above-mentioned lock gall dissects along axis, and wherein two assemblies are two slip courages, and two other assembly is two turn courages, and two slip courages are symmetrical arranged along the lock gall axis, and two turn courages are symmetrical arranged along the lock gall axis.
Two slip courage back segments in above-mentioned two slip courages are fixed together through connecting pin, and two another connecting pins of turn gallbladder channel are fixed together.
Two rotation lock rationed marketings on above-mentioned two slip courage back segments are 130 degree at the central angle of slip courage cross section circle.
Marble hole on above-mentioned two slip courages is a row more than 3 or 3, and the marble hole on two turn courages is a row more than 4 or 4.
The process of unblanking:
1, when key inserts lockhole, the pellet of slip lock gall (also claiming the slip courage) put in place (the upper pellet in the lock body, lock gall, the junction that lower pellet is in lock body, lock gall), promoting the slip lock gall moves ahead, make the pin on the slip lock gall break away from stopping of the lock body place of topping bar notch, thereby eliminate the resistance of lock gall rotation.
2, when pin disengaging notch stopped, the pellet of rotation lock gall was inserted into the position with key, and the pellet in rotation lock gall and the lock body also puts in place.
3, screw key, all lock gall rotations, the brace that is inserted lock by the lock gall rear end drives lock, dead bolt is rotated, thereby unblank.
4, when finish unblank after, extract key, the slip lock gall pushes back the original place with the slip lock gall under spring pressure, the pellet of lock body and slip lock gall is in the lock state.The pellet that rotates simultaneously lock gall also is in the lock state.
After key inserts lockhole, first pellet by the slip lock gall puts in place and (unties the locking of slip courage pellet, rotate the lock gall pellet and still be in the lock state this moment), then key continues to insert, and promotes the notch on the rotation lock rationed marketing release lock body on the slip lock gall, removed stopping of lock gall rotation, the pellet that rotates simultaneously on the lock gall puts in place, turn this moment key, lock gall unitary rotation, drive the dead bolt plectrum and stir dead bolt, can unblank.
The utlity model has following advantage:
1, this lock gall (being lock core) has structurally adopted the twin-stage unlatching, must just can untie the rotation lock rationed marketing with behind the key operated first order slip lock gall, and after the rotation lock rationed marketing was untied, the slip lock gall just can rotate; The second level be turn lock gall (also claiming the turn courage) in the situation that key puts in place, open pellet, rotate key, lock is opened.Owing to adopted the rotation lock rationed marketing, and rotation lock rationed marketing design has prevented that effectively present various master key is to the technical opening of this lock in the lock body that master key (prerequisite that master key uses is the lock gall rotation) can not be run into.
2,2 steady pins of (two) slip courage back segment and (two) rotation courage play anti-violence impact lock gall simultaneously.
3, two bayonet sockets (being limited impression) on the lock body are 130 ° of distributions, and purpose is for once contraposition of key rotating 360 degrees, makes things convenient for the user to open.
